IMPROVEMENT IN SULKY-HARROW.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom tt may concern Beit known that I, JAMEs E. Cunasnnno, ofMarilla, in the county of Erie, and State of New York, have invented certain new and useful Improvements in Sulky- Plowand Harrow; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, in which- Figure I is a plan ofthe sulky and harrow.

Figure II is a longitudinal section of the sulky and gang-plow. i v

.Figure III is a vertical section ofthe cast-iron sleeve, forming the brace for the guide-stirrup.

Like letters of reference designate corresponding parts in all of the figures.

The present application relates to a certain invention heretofore secured to me by Letters Patent ofthe United States, bearing dateOctober lo, 1866, and ninnbcred 58,773, and is designed as improvements thereon, reference being here made to tbeschcdule and drawings annexed to said patent for a full description of said original invention.

My impiiovements consist- First, in the arrangement of the three parts or lesser drags, which together forni a single harrow.

Second, in the combination and arrangement, with the barrow, oi' a cross-bar and connecting-chains for elevating the former. Y

Third, in the arrangement forming the draught-attachment to the barrow.

Fourth, in the construction and arrangement of the casting by which the tongue is attached to the sulky, and rendered adj ustablc;

As represented in the drawings- The sulky consists ot' an axle, A, two wheels, A1 A, tongue, A1, and two diagonal braces, Ai A3, constructed in any suitable manner.

B is the guidc-stirrup, descending from the under side ol' the tongue.

On this stirrup is a slide, C, which freely moves thereon, and terminates in hooks c c', at the front and rear, for attaching the draught, as will presently be described.

My machine is designed to be used alternately as a gang-plow or as a barrow, as 4may be required.

The gang may consist of any suitable number of plows, (three being sliowln) arranged in any suitable frame H, and attached thereto by the usual standard d.

The front end of the frame H, of the gang, connects with the rear hook c, of the slide G,by a clevis, in any ordinary manner.

'Ilorelieve the friction otf the plows on the bottom and landside, I connect a chain, t, from the central plow to the axle oi' the snlky, so that it will incline from the landside. 'Ihe length ot' this chain being regulated to the required depth of the furrow, the weight of the plows, and pressure thereon, will, in a great measure, be sustained by this chain, while its inclination will tend tocounteract the pressure against-the land, thereby preventing that great amount of friction on theV consequently dispensing with the power that is usually required to 'overcome the same vWhere no such means are employed.

f The entire gang is elevated and suspended above the ground, whererequired, in travelling from place to place, by means of a windlass, or segmental wheel, I, lever, I, and chain, fi, as set forth in my former patent before alluded to.

The gang may be provided with handles g, while a seat, J enables .the driver to ride, and at the same time steady the plow if required.

In Fig. III the guide B is shown provided with a cast-iron sleeve, F, so formed as to present a broad bearing-suriitce, j, to the under side of the beam where it is arranged.

VThe brace is cast with a hole, to permit the passage .of the end,b, of the stirrup, which is reduced in size, so as to have a shoulder, b', for the sleeveto rest upon, as clearly represented.

The sleeve, or brace F, may be further secured to the beam by screws or bolts passing through the flange-portionj, if required. This arrangement eifectually braces the stirrup, while it leaves the latter free for the movement of the slide, and the attachment of the draught and plow or harrow, which the diagonal brace, as heretofore employed, did not.

and similar lesser drags, K K K, of the common A-form. These I arrange side by side, with the apices of the two outer ones in front, while that of the intermediate one is reversed, so that the innersides of the outer drags ,will lie parallel with the proximate sides of the middle one, K.

The three drags I prefer to connect together by eye and staple-couplings L k, although they will maintain their proper relative position without such connections.

L is a draught-bar connecting at the centre with the forward hook c of the slide, and at the ends with the apices of the drags K K, by means. of rods l l, or their equivalent.

The central drag K has draught-bars, or chains. Z l', from each side, connecting with the rear hook c of the slide. By this method of attaching the draught, all of the drags have their proper connection, which causes them to maintain their relative position without any coupling-device between them.

The arrangement of the barrow, as above described, leaves ample space in the angle of the outer drags K -for the wheels of the sulliy, which renders the machine very compact, and brings the sulky nearer the draught.

For elevating and suspending the barrow, in travelling to and from the tield, I employ a` cross-bar, M, with three chains, m m m, radiating from the underside at points centrally over each drag, and attaching to each, as represented.

Immediately above this cross-bar, I arrange pulleys a n, attached to the braces A3 A3, over which pass chains bottomand landside which is usually engendered, and

My improved barrow, I construct of three separate p2 p2, fastened to thebar beneath, and connecting with sertion of pins or bolts u through'holes formed in them.

Transverse notches 'w are formed in the upper surface of the tongue, in which the said' pins rest, thereby rmly holding the tongue in place.

The braces may be fastened by screws from the under side.

The upper surface of the bed, for the tongue and braces, may also, if desired, be east with a transverse bead, designed to lit in corresponding notches in the tongue and braces, which will operate to hold them against Athe longitudinal strain resulting. 'om the draught.

A double series of notches, fw, are formed in the upper surface of the tongue, to permit of its adjustment, so as to'shorten the same, which is required when the plows are employed as shown in Fig. II. This adjustment, the construction. of the casting P readily permits, which is of considerable importance in diminishing the power required to. draw the machine.

My machine is of such size as to require four horses for operating it. These I 'arrange all abreast, two on each side of the tongue.

Each of the foregoing-described features of my invention is essential, and contributes to the general Vresult, the production of a e'omplete machine, 'readily convertible into a plow or harrow, as required, the same sulky being used for both.

' With myimproved machine a single person can, with comparative ease, perform the work which usually requires two and sometimes three hands, and as many different machines.

What I claim as my invention, is-

l. The arrangement ofthe drags K K K with each other, and with a sulky, as set forth.

2. The combination and arrangement of the crossbar M andthree sets o1' supporting-ehains 'm m, lm, with .the harrow K K K and elevating-devicen p I, or its equivalent, as herein set forth.

3. The combination and arrangement ofthe draughtbar L and connecting-bars or chains Z l Z' Z with the slide C and harrow K K K, substantially as specified.

4. rIhe casting I, constructed with ledges, p and pl, the braces A A, tongue A2, and pins u u, adjusted, arranged, and operating as and furthe' purpose set forth.
