GEORGE C. VIDETTO, 01E PITTSBURGH, PENNSYLVANIA,

convnrrne arrnnarus.

To all whom it may concern:

Be it known that I, GEORGE C. VrDn'r To, a

citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invent-ed oer-- ,tainnew and useful Improvement in Con a portable truck having a receiving conveyor, adapted to be set at various angles or degrees of incline and to discharge the load from its outer end, and a loading drum so connected, with the-conveyorv truck and with relation to the conveyor as to remove the material from its position in the pile or bank to theconveyor, together with suitable driving mechanism and various other features'of construction and operation, as

shall be more fully hereinafter described.

Referring to the drawings, illustrating one preferredembodiment of the invention,

Fig. 1 is a view in side elevation of the entire apparatus in position for operation;

Fig. 2 is a plan view of Fig. 1;

Fig. 3 is a view in elevation from the innor end; and

'Fig. 4 is a transverse sectional View on the line TV--TV of Fig. 1.

The main framework of the apparatus, comprising the supporting truck for the conveyor, is built of suitable structural material having the main side beam members 22 of channel or other suitable shape, with end framing 3. The main truck is supported upon a pair of driven wheels 4= land front dirigible wheels5-5. The rear portion of the machine, comprising the removing wheel portion, is carried by a supplemental supporting frame 6 composed of two side bars similar to bars 2, and each is pivoted by cross shaft 7 in the brackets 8 and}? respectively of the two main frames. The purpose of such mounting is that the rear framework carrying the removing drum may be adjusted vertically with rela- Specification of Letters Patent.

tion to the main conveyor frame, to adapt it to inequalities in the ground surface, the pile of material being acted upon, or other conditions.

Extending upwardly and rearwardly from the main frame 2 are the posts 10-10 connected by stay rods 11 to the main side bars 2 and provided with a transverse shaft 12 and sheaves 13 thereon for the lifting Said cables are connected at each side of the supplemental frame 6, as at 15, pass upwardly over sheaves 13, and then downwardly and around the winding drum 16 of shaft 17 having the ratchet controlled windin gearing 18 of well known construction, w ereby the drum frame maybe raised and held at any desired position or elevation, or may be lowered below the normal horizontal level, as required.

The digging or removin drum .or wheel, which is the initial active e ement of the a paratus, is mounted upon a transverse shaft 19 in the rear end portion of frame 6, and is pockets similar to the usual pockets of an ordinary bucket conveyor.

The edges 21 may be merely continuous terminals of the metal of the buckets, as in operation. on ordinary loose material, as sand, etc, but where it is desirable to opcrate upon coarser material, as heavy gravel, lump coal, or similar material, I prefer to provide at one or more locations around the periphery of the drum, as for instance, along each alternate edge of the bucket series, a series of projecting teeth or points 23 secured by their inner terminals 24 to the edge of the sheet metal, as will be readily understood. lln such case, the teeth will operate to cut through coarser material, segregating and loosening it, rendering it possible for the plain edge buckets to scoop and elevate it and carry it around for deposit upon the receiving end of the conveyor A.

Said conveyor may be of any suitable construction, as a belt 25 passing around an inner driving drum 26 and an outer drum 27 mounted in adjustable journal boxes 28, carried in framework 29 of the conveyor, the inner end of which is pivotally mounted on transverse shaft 7, and capable of vertical adjustment. Conveyor belt 25 is supported in any suitable way, as by a series of upper and lower transverse rollers 30-3l of well known construction.

Lifting post 32, bearing upon the under side of the conveyor frame by one or more rollers, is mounted upon the end framing portion of the main truck 2 having the guiding housing 34 and a lifting'cable engaging a terminal sheave 36, and provided with. a winding drum 37 and suitable ratchet controlled gearing 38, whereby the elevator A may be located at any desired inclination for delivery from its outer end.

Ordinarily, the conveyor A and the removing drum, generally designated by the letter B, are operated together, by means of sprocket gearing 39 and ll), utilizing the usual sprocket chains and wheels, whereby to transmit movement from the shaft etl thereto. Said shaft 41 is driven by sprocket gearing a2 utilizing the usual chains and wheels, from shaft l3, which is driven through gearing l-l from a motor or other prime mover Clutch mechanism 46, operated by lovers 4? and i8, is adapted to transmit driving motion in the desired direction to traction wheels 4 through gearing L9 and 50 of each traction wheel. whereby to propel the apparatus forwardly or bz'iclnvardly. A clutch 51 between the oppositely driven bevel gears 5252 of shaft 43 and operated by lever 53, provides for reversing the direction of shaft i1, it being understood that clutch 46 may be thrown out of gear at any time. as for instance, when the digging and scoop loading-drum B would otherwise be operated in an undesired reverse direction.

By the gearing above described, it will be understood that traction may be imparted to the main truck wheels a for transportation of the apparatus, in which case the removing drum may be elevated away from contact by its lifting .mechanism 14. etc., and that when located in position for operation with the removing orloading drum lowered, the traction gearing is inactive. the power of the motor being then utilized to drive the conveyor and removing drum together.

It will, of course, be understood that a gas engine or other prime mover may be substituted for the electric motor -15 shown in the drawings and that the invention is in no Way restricted to the particular kind of motor utilized. Guiding mechanism for wheels 5 of any suitable kind may be used, as knuckles 5e connected with a cross rod actuated by lever 56 and gearing 57 provided with a hand wheel 58 generally similar to that utilized in clutch mechanism.

The construction and operation of the invention will be readily understood and appreciated from the foregoing description. Mounted upon the main supporting frame as it is, the machine may be transported under its own power over any suitable surface, and located in position to operate upon a pile of loose material C, as for instance, sand, coal, or the like. Drum B having been adjusted and conveyor A raised to the desired inclination, as for instance, sufficiently high to deliver into a receiving wagon. mine car, or the like, gearing 39, 4.0 and i2 will transmit driving movement simultaneously to the drum and conveyor, so that the drum, in its rotation, will scoop up segregated quantities of the loose material of the pile and will deliver them o to the receiving end of the conveyor, which will then carry the material outwardly in the usual way, and deliver it over the terminal drum 2? by gravity.

The apparatus is very compact, comparatively simple in construction and operation. light and portable, and inexpensive to build and maintain. It is capable of being used in many lo aitions where it can be substituted for manual handling of the loose material, as in quarries, mines, or elsewhere, and is well adapted to perform its intended functions in a highly satisfactory manner.

The invention may be variously changed or modified by the skilled mechanic in various details or otherwise, but all such changes are to be considered as within the scope of the following claims.
