LOADING APPARATUS.

Application filed August 8, 1917. Serial No. 185,038. I

To all whom it may concern:

Be it known that I, CLARENCE A. VEINo'r, a citizen of Nova Scotia, Dominion of Canada, residing at Waterville, Kennebec county, and State of Maine, have invented and discovered certain new and useful Improvements in Loading Apparatus, of which the following is a specification.

My said invention relates to loading apparatusand consists in the combinations and arrangements of elements hereinafter described and particularly set forth in the accompanying claims.

The invention has for its purpose to provide an apparatus adapted particularly for loading logs and the like, which may be readily transported from place to place and operated for lifting the logs from the ground to different elevations, and having means for adjustment, to the end that the apparatus may work with equal facility for elevating logs to the different higher levels.

The invention has for its further purpose to provide a log elevating apparatus constructed to work from either side of the material from a given position.

Another purpose of the invention is to produce an apparatus of this character, which may be set for operating in a substantially horizontal plane, when the elevators may work after the manner of the ordinary horizontal conveyers.

The invention further contemplates constructing an apparatus of this character and mounting the same on a motor-driven vehicle, to the end that the loader may be readily transported to the place for working, and there positioned with regard to the distribution of the material to be handled; and wherein the construction and arrangement of the whole is simple and may be readily controlled.

The invention is disclosed by way of illustration in the accompanying drawings, wherein- Figure 1 is a side elevational View thereof,

Fig. 2 a top plan view of the same,

Fig. 3 an end elevational view,

Fig. 4 a transverse sectional view, taken on the line 4r4t of Fig. 2.

Fig. 5 is a similar view, taken on the line 55 thereof,

Fig. 6 an enlarged detail view, in section, taken on the line 6 '6 of Fig. 2, and showing the turntable construction,

Specification of Letters Patent. Patented Sept. 10, 1918.

Fig. 7 an enlarged detail view, on the line 77 of Fig. 1, of the transmission gearing for the elevating mechanism and conveyer chains.

Fig. 8 a detail view of the transmission and clutch control thereof, for the turntable, and

Fig. 9 a top plan view of the tractor wheels and driving gear therefor.

Referring to the construction in further detail and wherein like reference characters designate corresponding parts in the diflerent figures, 9 indicates the body of any suitable vehicle or tractor, having steering wheels 10, tractor wheels 11, a driving engine 12, a suitable driving gear chain 13, a seat 14 for the operator, and a suitable control 15, after the manner shown. The loading apparatus is mounted on the body or frame 9 of the vehicle, hereinafter referred to as the supporting structure; and motor 12 is utilized for operating the loading apparatus in the manner herein stated.

The loading apparatus consists of a revoluble platform or body 16 mounted on the king-bolt 17 (see Fig. 6) and carrying a plurality of rollers 18 that travel on the annular track 19 secured to the supporting structure 9. Said turn-table 16 is mounted on the bearing block 20 that receives the king-bolt 17 by means of a number of ordinary fastening bolts 21, or in any other preferred manner.

A frame 22, comprising a plurality of parallel beams (see Figs. 1 and 3), is mounted to swing on the shaft 23 that is journaled in suitable bearing blocks 24 secured to the turntable 16 along one side thereof, as shown. Said frame has journaled therein, on the respective ends of the beams 22,

a pair of shafts, 25 and 26; and a plurality of sprockets 27 are mounted on said shafts on the respective ends of each beam. An endless chain 28 is mounted to travel on each pair of sprockets, and said chains are provice, is provided for cooperating with the main conveyer chains 28, and acts as a feeding conveyer or loader for said main conveyer chains. Said device consists of a pair of arms 30, that are swiveled on the shaft 26; and a sprocket 31, journaled in each of said arms at the end, carries a chain 32 which rides over a similar sprocket 33 secured to the shaft 26 within the sides of'the arm 30, as shown in Fig. .1. Said chains 32 are, in like manner, provided with projecting members 34 for engaging the artlcles carried.

The chain supporting frame 22 is adapted to be elevated in accordance with the height to which the logs or other material are to be delivered; and said elevating device consists of a plurality of screw-threaded shafts 35 that are connected to suitable hangers 36, mounted on the shaft 37 that is journaled on the frame bars 22. Said elevating shafts 35 are severally connected to be driven from the shaft 37 by the miter gears 38, whose pinions are mounted on the

shafts

37 and 35, within said hangers 36. The connection between the several shafts 35 and the platform 16 consists of threaded nuts 39 that are swivelly mounted in the brackets 40, secured to the under side of the turn-table 16, as shown (see Fig.

The shaft 37, which directly drives the elevating shafts 35, is itself driven from the sprocket 43 through chain 41 that rides on sprocket 42 on said shaft 37, and miter gear 44 driven from the counter shaft 45 engages and drives the sprocket 43. The shaft 45 is, in turn, driven from the main driving shaft 46, through either of the trains of gearing shown in Figs. 4 and 5, accordingly as the screw rods 35 are to be rotated in one direction or the other for raising or lowering the frame. For rotating the shaft 45 in one direction, the pinion 47 on shaft 46 drives pinion 48 on shaft 49, and meshing with pinion 50; and said pinion 50 meshes with pinion 51 mounted on the shaft 45. A clutch 52 serves for coupling the pinion 51 to rotate the shaft 45, when in one position. For rotating the shaft 45 in the opposite direction, the clutch 52 is moved to couple with the pinion 53 on shaft 45, and said pinion 53 meshes with pinion 54 on shaft 49 (see Fig. 5). The pinion 54 is driven directly from pinion 55 on the counter shaft 46. The shaft 46 is connected to be driven from the main driving shaft 56 of the en ine, through the miter gear 57 (see Fig. 2.

The transmission gearing for operating the several carrying chains 28 consists of a chain 58, riding on sprocket wheels 59 and 60, on

shafts

25 and 23 respectively. The sprocket 60 is keyed to the shaft 23 (see Fig. 7) and is driven from the counter shaft 61 through the miter gear 62; and shaft 61 is driven through the gear train 47, 48 and 50 (see Fig; 4). A clutch 63, slidable on the shaft 61, serves to connect the pinion 50 to rotate said shaft. The usual hand operating devices 64 and 65 are provided for shifting the clutch elements 52 and 63, respectively. It will therefore be seen that the several chains 28 of the loader are operated simultaneously from the shaft 25, driven through the gearing (58, 59, 60 and 62) and thereby the lower, or supplemental carrying chains 32 are operated.

The turn-table 16 is adapted to be rotated by a screw gear 66 on a shaft 67, and meshing with a worm wheel 68 that is formed in thebearing lock 20 of the turn-table. Said shaft 67 is driven from the engine shaft 56 directly through the

gear wheels

69 and 70, or indirectly thereby to obtain the reverse operation through the

train

71, 72, and 73. A clutch 74 is shiftable to connect the shaft 67 to be driven from either of the pinions or 73,, after the usual manner.

The duplicategears 44 and 62011 the free end of the shaft 23 (as seen in Figs. 2 and 7) are adapted for engaging with the miter gears 75 and 76 respectively, on the free ends of the shafts 45 and 61, in order that the working parts of the loader may be operated from either side of the vehicle.

A suitable detent. device is provided for holding the turntable in either of its positions of operation, and said device consists of a spring pressed lever 77 adapted to engage in-recesses 78 formed in the members 79, and adapted to be operated by a treadle 80 (see Figs. 1 and 3) located in proximity to the operators seat 14, which serves for releasing the lever 77 and when the gearing is thrown in to rotate the turn-table.

The engine 12 is mounted on the forward end of the frame 9 or directly over the steering wheels 10 which thereby carry virtually the entire load of the engine. The seat 14 for the driver is located substantially midway between the loading apparatus and the motor to evenly distribute the weight and have the operator in the most advantageous position for running the car and for controlling and directing the operations of effort while traveling over uneven surfaces.

The several wheels are connected to'be positively driven from the motor by a suitable driving gear comprisinga chain 84 riding on sprockets 85 and connecting the firstand third axles 80; a second chain 86 connecting sprockets 87 on the third and fourth axles; a third chain 88 connecting sprockets 89 on the second and fourth axles; and said third axle is directly driven through the transmission chain 13 from the motor.

It is obvious that those skilled in the art may vary the details of construction and arrangement of parts without departing from the spirit of my invention, and I do not therefore wish to be limited to such features except as may be required by the claims.

Having thus described my said invention, what I claim as new and desire to secure by Letters Patent, is:
