JONAS F. YOUNG, OF NIAGARA FALLS, NEW YORK.

Specification forming part of Letters Patent No. 181,887, dated September 5, 1876; application filed May 11, 1876.

To all whom it may concern:

Be it known that I, JONAS F. YOUNG, of Niagara Falls, in the county of Niagara and. State of New York, have invented a Oompound Ditching and Tile-Laying Machine and I do hereby declare that the following description, taken in connection with the accompanying sheets of drawings, forms a full, clear, and exact specification, wherein are set forth the nature and object of my invention, and ghe best mode by which it is carried into efect.

The object of my present invention is the production of a machine that shall cut a ditch, deposit the necessary tiles, and cover the excavation in one operation. To this end I construct a portable frame of suitable material and dimensions, having a sliding frame operating in uprights, to which sliding frame I attach an anger revolved by suitable machinery, and also'an elevator receiving its motion through properly-arranged gearing and connections, in such manner that the earth or soil cut by the revolving auger shall be raised out of the excavation by said elevator, and deposited either on the sides of or directly into the same again, at some distance from the anger, as the case may be. Directly in the rear of the elevator, I locate a vibrating inclined chute, upon which I deposit the tiles to be laid into the excavation, said vibrating chute being in communication with a fixed spout or tube' passing to the bottom of the ditch, through which said tiles pass in their way to the saidditch, the vibrating of the inclined chute causing the tiles thereon to move toward and into the fixed spout, down which they will slide by their own gravitation, and arrange themselves successively in a continuous line, as the machine moves forward, which is accomplished by a drum upon which a rope is wound by the action of the machinery.

In order to elevate and lower the anger, as necessity requires, I suspend the sliding frame carrying the bearings for the auger by means of nuts engaging with properly arranged screws operated by a bevel-gearing. All the operating parts of my machine are set in motion by animal or other power.

4 The drum by means of which my machine is propelled is provided with means for instantly varying or arresting the speed or forward movement of the machine, as circumstances may demand.

To enable others skilled in the art to which my invention appertains to make and use the san1e, I shall proceed to describe its particulars of construction, and thereby refer to the hereinbefore-mentioned drawings, which form I a part of this specification, and illustrate my invention more fully.

In these drawings, Figure 1 is a longitudinal sectional elevation.v Fig. 2is a plan. Fig. 3 is a front elevation. Fig. 4 is an elevation of the auger detached. Fig. 5 is a perspective'view of a detached cutter. Figs. 6, 7, and 8 are detached views of various operating parts.

'Like letters of reference indicate corresponding parts in all the figures. j

A are two longitudinal beams of wood, of proper dimensions to sustain the superstructure. They are placed parallel a suitable distance apart, and connected on their extremi-' .ties by the transverse beams A.

Centrally attached to .each of the longitudinal beams, by suitable connecting-timbers, are two uprights, B, connected with each other on their upper end by the plate 0, or other suitable means; These uprights are placed a sufficient distance apart to allow the introduction of a rectangular frame, D, sliding in the space between the uprights, said frame D being suspended by means of nuts D engaging with two vertical screws, E, extending from near the upper end of the uprights B down to the longitudinal beams, and revolving thereupon within the stepbearings E, and on their upper end in bearings E secured to the connecting-timbers F. The screws E receive motion from the transverse shaft G through the bevel-gearings H, the shaft itself being rotated by the bevel-wheels I connecting with the main driving-wheel J. In order to elevate or lower the frame D, it is necessary to revolve the screws E in the proper direction, and to accomplish this object I arrange the bevel-wheels I loosely upon the shaft G, and provide each with a friction or other clutch, I, operated simultaneously by the-levers K.

and connecting-bar K in such manner that when one of the clutches I is thrown into gear the other will be disengaged.

The wheels I revolve in opposite directions, so that the proper clutch, engaging with the corresponding wheel, causes the shaft G to revolve in one direction, while the opposite.

p the shaftG, to communicate motion to the auger O by means of the bevel wheel N keyed to one end of said shaft N, and engaging with the main driving-wheel J and a belt-pulley, N, on the opposite and forward end of said shaft. This belt-pulley N is provided with a friction-clutch, as clearly shown in Fig. 1, for'engagement and disengagement, and it connects, by means of a chain or other endless belt, T, with the pulleys P P, revolving with their shafts within hearings in the bracket Q attachedto the frame D.

To-the rear end of the shaft carrying the pulleyP is fastened a bevel-wheel, R, engaging with the double-faced bevel-wheel R, arranged to revolve horizontally, and with the bevelwheel R, constructed to turn in a horizontal plane, the latter one being attached to the auger-shaft S, and the former to a suitablyarranged shaft, S, having its bearing on the side of the sliding frame D to communicate motion to the elevator X, as hereinafter to be described.

The auger-shafts has two bearings attached to the frame D, within which it revolves, and it is provided on its lower ex tremity with the auger O. The endless belt 1 passes from the pulley N to the pulley P,- thence upwardly over the pulley P, and then downwardly over the pulley U secured to the shaft U. This pulley serves to'rotat'e a differential gearing, consisting of a series of gear-wheels of different diameters attached to said shaft U, and engaging with a correspondingv series of similar gear-wheels, U, revolving loosely upon the; shaft U. one of the latter series of gear-wheels, when engaged with the shaft U by means of the (lllltchjU will cause this shaft to partake of its motion, and thereby to revolve the drum V by means of the bevel-gearing V. This drum serves-to propel the machine by thev rope V, fastened with one end to arfixed point in advance of the machine, and winding upon said drumas it revolves. The speed or forward movement of the machine is controlled by the differential gearing heretofore mentioned, and it may be arrested .by throwlug the clutch U out of gear.

elevator bucket driving shaft.

pinion a.

Either- So far as the different elements hereinbefore described are concerned, they relate to the production of the excavation for the deposition of tiles, which is accomplished by the verticallyrevolving auger O, which will cut the soil lon gitudinally as the machine advances. The loose earth is removed by means of the elevator X, which is driven by the shaft X, having on its lower extremity a bevel-pinion engaging with the double-faced bevel-wheel R, and near its upper end a corresponding bevel-pinion engaging the bevel-wheel X attached to the The upper bevel-pinion slides upon the shaft X by a feather and groove, and it revolves within the movable bearing Z.

The elevator X is suspended between four brackets, Z, secured to "the rear side of the sliding frame D, and is raised or lowered by a rack and pinion, a, and a shaft and handle, b, from the forward end of the machine. The brackets Z, as well as the shaft and handle I), are secured to the sliding frame D. By this arrangement the elevator X may be raised or lowered simultaneously with the auger O, or independently of the same by the rack and c is an inclined chute, moving horizontally by means of grooved wheels 0, or similar'con trivance, upon the rails 0, attached to one of the lower brackets Z. This chute is vibrated from the elevator-bucket shaft by means of the cog-wheel d engaging a similar wheel, 01, provided with a crank-pin, 6, operating in a slot-hole of the lever f, said lever being pivoted to the support f attached to one of the upper brackets, Z, and connected withth chute c by the links 0'.

The. crank-wheel d has its bearing in a hand-lever, f, pivoted to the support f, and provided with means for adjustment, such as a set-screw, f, passing through a slot hole in the hand-lever f into the support f.

Other devices, however, may be resorted to to accomplish the object of vibrating the inclined chutec, if desired. This chute 0 inclines toward the center of the machine, and has connection on its lower end with a fixed spout, g, pivoted to a support, 9', fastened to one of the lower brackets Z, opposite the rails c. This spout, g is constructed of two pieces hinged centrally,and it is manipulated by a winch, 71,, and a chain or rope attached with itsend to the cross-bar g of the lower piece of the spout g, and passing over a similar bar, g, on the lower extremity of the upper piece of said spout. The spout g, on account of its being attached to the sliding frame D, through the intervention of the brackets g and'Z, partakes of the motion of said sliding frame; but to adjust it in the ditch, and to raise it entirely above the ground for portability, I have resorted to thehereinbefore-mentioned Winch d.

The whole machine is rendered portable by means of wheels placed on the front and rear near the outer ends of said axle.

grooved wheels placedbehind the -piv ote'd. spout direction.

a After the machine has commenced'to cut to the proper depth l deposit thetiles to be laid it is governed by means of the hand-wheel operatinga chain passing over a chain-pulley,

and attached with its both ends to segments secured to said axle. The rear axle is pivoted centrally to the rear tranverse beam A,

andis adj ustably retained in position by means of the toothed segments 3- and 4 attached One of these segments, 3, is operated by the pinion 5, at-

tached to the shaft '6, which extends longitudinally to the platform, and is actuated by a worm and worm-wheel, 7, operated by the handle 8, fastened to an upright shaft passing through the standard 9. The other segment,

4,communicates motion to a brake, consisting of a drum, 16, and a brake-shoe, l7, operated -by the lever 10, rod 11, bell-crank 12, rod 13, and the foot-lever 14, which latter is provided -witha-toothor serrated stop-bar, 15, to retain said treadle 14 in any desired position.

" The segments 3 and 4 are provided with,

curved plates on their faces, engaging with pinions engaging with saidsegments. v

When the machine is moving forward it tendency is to cause bending of the rear axle, and t0 remedy this I have resorted to said curved plates and grooved pulleys or wheels to keep the rear axle in'close contact with the rear transverse beam A, and thereby the segments and pinions 3'and-4 in gear.

In order to cut a ditch, the machine, being brought upon itsfield of action, is started by hitching the requisite number of animals to the sweeps, and the gear that operates the pinion a.

If desired, the drum V mayibe caused to revolve' with the augerythe rope-V having --b'een' previously fastened to a stake in advance {of-the machine;- By this mode I start the ditch with aslope, and continue until the desired-depth of theexcavation'islattained- In this case the elevator X needs'to'be kept suspended only for ashort distance above'the 1 lower extremity of the auger,'and it can be caused to descend as the machine advances. As'soon as the proper depth is reached the movement of the frame D is arrested, when the inachin'e will proceed to cut longitudinal-- ly an excavation, whose bottom is); parallel; with the surface of the ground over whichit' has traveled. 'Thesoil detached by-the anger is raised" by theelevator; X, and deposited 'eith'er o'n 'oneorthe other side of the e'xcava, ti'on, or back into the same, by'means of the to be cut.=wi th1a uniformiysslopingbase.

, which may be swungiin' any into. the excavation upon the vibrating chute 0, side by side, which chute, being arranged on an incline, will cause these tiles to movetowardthelower end thereof. This lower end is inclined toward the rear of the machine or at an angleto the base of the vibrating chute, said inclination beginning about midway, so that when :the tiles reach this-end they will incline toward-the rear end and drop into the pivoted spout g. This spout contains a sufficient number of. tiles, which, resting one upon the other, exert sufficient pressure upon the lowest one to-cause-it to leave the spout as theLmachine. advances. [u this way the tiles arrange themselves in a continuous line in'the ditch, which is at oncecoveredup with the dirt removed by the auger in front, and the ground restored to its original condition. tilesofa smaller size or of varying sizes must be laid I arrange the sides ofthe depositingspoutg in such manner .as to beadjustable to the size of the tiles. It is necessary that this spout-shouldcorrespond to the tiles to be deposited, in order to form a straight line when laid into the ditch. In order to cut. the bottom of the. ditch ina-straight line withoutregard to-the undulations of the ground over .which: the machine passes, and, also, to cut. a ditch with a perfectly uniform {sl0pe,LI. pro- 'videthe slidingsframe with a leveling device, consisting of the horizontallyrsuspended bar f, pivoted in: a. universal joint, K, from. the sliding frame D (withthe. center of motion in line with: thevcenter, of the;augerv-shaft,) and provided on its forward: extremity with the sighting device composedof. two horizontal bars, i l, pivotedto awconnecting-bar, Z,,= and provided with hair-linesm. Thisqsighting devicez has :a: universal movement, and it oper- :at'es in.- conjunction witha stake placed at. the

:machine inregardto .theqfixed pointnof the stake; and if hefinds that the hair-lines point to a position above the mark,itindicatesthat thetsliding frame D should be lowered, or vice-versa. T If this adjustment is frequently madethecut will be of a nearly perfect slope, ino matter. how irregular the-surface, of the operating field may be. To cuta ditch with to the brake-shaft.

curely held in position. this adjusting arrangement to the rear axle,

side-hill, and make its walls perpendicular, the machine must be tilted accordingly. This I accomplish by the adjusting device on the account of the backlash in the teeth of the adjusting segment and pinion, I provide the opposite end of the rear axle with the segment 4, which actuates the brake-drum 16 in such manner that, when the brake 17- is applied by means of the treadle l4 beingdepressed, it will securely hold the pinion applied If, no\v,-a slight turn will be given to the handle 8, the play in the teeth will be taken up, and the machine thereby se- I have only applied and pivoted the front axle in a universal joint, which will allow said front axle to adjust itself to the various positions of the machine.

To avoid stumps, or other surface obstacles in the field, and also to cut curved ditches, and, furthermore, for portability of the machine, the front axle is pivoted in such manner that the machine can turn a-curve, and thus avoid any obstruction that may be in its path; If the machine should strike a large stone, or other obstructions buried in the ground, the operation of the auger and winding-drum is arrested by disengaging the friction-clutch N and the auger elevated by the elevating-gear. The obstruction can then be removed by suitable hand-tools, and the position of the'auger restored. Should these obstructions be of such a nature as to be insurmountable by the machine, it will benecessary to advancethe same and to begin a new ditch at a place past such obstructions, the unfinished space between having to be excavated by manual labor.

As heretofore stated, the friction-clutch on the pulley N is operated by means of ah'and wheel and screw in such manner that any amount of friction can be caused to exist between the pulley and the clutch. By this arrangement I am enabled to adjust the friction so asto cause the pulley to slide ontheclutch, should the anger strike an obstruction, which would cause increased friction, or arrest its motion entirely, thereby also decreasing or entirely arresting the forward movement'ot' the machine, and avoiding'undue strain on or breakage of the'moving'parts.

It will be observed that the cutter O is constructed ofthe two helical plates 0, jointed on their lower extremity by the dou-ble-lipped late 0 and attached with their'upper end to the head 0", said bands being set into recesses in said head and held in position by the band it shrunk thereon. the advance edges of the plates 0' form the cutting-edges and the interior of the said anger a passage for the soil toward the elevator. If desired, the bands may be provided with connecting-pieces for stability. The leg of the elevator, which may be covered or open, and the buckets therein, are of a width slightly less than the diameter of the auger, so that the dirt is all removed from the ditch, the speed of the buckets being such that the capacity of the elevator is considerably in excess of the work to be performed.

In order to cut ditches of different width, I

change either the auger and elevator or the auger alone. In this case I construct the elevator of a width corresponding to the narrowest excavation, and provide its leg with scrapers or othersuitable means, to collect and con a vey the dirt to the elevator-buckets. As hereinbefore mentioned, the advancing edges of the auger-plates 0 form the cuttingedges, and these are beveled and quite sharp. This construction will answer in most all cases i in ordinary soil; but if a very loamy or gravely soil must be excavated, I may provide the bands with detachable cutters p, as illustrated in Figs. 4 and 5, consisting of narrow curved pieces, q being the cutting-edge, r a shoulder resting against the cutting-edge of the plates 0, t an aperture in the cutters for attachment to said sides by means of said bolts, and s the shank, by means of which the cutters are applied. These cutters are made of cast-steel, properly tempered, and may be removed from the auger when d'ull, or for renewal when the vdriving-wheel d. In this case the elevator-chute will be swung over to'deposit the a separate portable bridge to the rear end of the machine.

' My. machine will cut excavations of any practicable depth, and deposit the tiles therein automatically, on account of the int'roduc- 7 tion of the sliding frame D, to which all the operative parts except those causing the for-- a ward movement of the machine are fastened.

It will also cut ditches for sewer, gas, or water pipes or, it kept stationary, and provided with a suitable earth-auger, for digging postholes, and for many other purposes. 1- Iwill here call attention to thearrangement,

In this manner ing'of the belt. flexible material, as leather, rubber, &c., or

. to correspond with the chain.

I I will here further call attention to the difwith the pulleys P P, of the gear-wheels P P, attached to said pulleys. This I have designed to add the tractive forceof the belt 1 passing over the upper idle-pulley P tothat ,ofxthe driven pulley P, which thereby increases the capacity of said pulley. The idlepulley P is rendered necessary, to allow the operation of the machine in all the various positions of the sliding frame without slack- This belt may be either of it may be a properly-constructed chain, the latter being preferable on account of its greater strength, and thecomparatively slow speed of said belt, which is, perhaps, less than the proper working speed of a leather or other flexible belting. If a chain is employed, the grooves in the pulleys are properly recessed ferential gearing for the rope-drum, which embodies several novel features, the principal one being that of instantly varying or arresting the speed of said drum. This is accomplished by means of a sliding key, 0, attached to the clutch U", and operating in a keyway upon rails, in conjunction with the anti-fric tion rollers e, I may suspend said chute by suspension-rods from above, or support the same by pivoted braces from below, which means I consider mechanical equivalents for the rollers as described.
