APPARATUS FOR. LOADING COAL.

Specification of Letters Patent.

Patented Nov. 2, 1909.

Application filed April 9, 1907. Serial No. 367,293.

To all whom it may concer/n.:

Be it known that I, VILLIAM LARsnN, a citizen of the United States, residing at Honolulu, county and Island of Oahu, Territory of Hawaii, have invented a new and useful Apparatus for Loading Coal, of which the following is a specification.

My invention relates to that class of apparatus used for receiving loose material and raising the same to a suitable elevation and then dumping the same; and particularly to apparatus adapted to handle coal or the like, receiving a load dumped from a cart or wagon, and elevating and automatically dumping the same, for example, into a bin or onto a vessel or scow.

The object of my invention is to produce an apparatus of this character which shall be portable, easily manipulated, and rapidly and economically operated.

The invention consists in the novel construction and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in which corresponding partsV are indicated by similar characters of reference, in which- Figure 1 is a side elevation of an apparatus in its working posit-ion for loading coal or the like. constructed in accordance with this invention. Fig. 2 is a side elevation of the same in position for being moved. Fig. 3 is a plan view of a portion of the body of the apparatus showing winch and motor operating mechanism. Fig. l is a plan and Fig. 5 an elevation of a portion of said body showing automat-ic guide for wire rope on winding drum.

The body 1 of the apparatus is composed of longitudinal sills 2 and transverse pieces 3 securely fastened together and mounted upon wheels 4 in a well known manner. Iii-- clined beams 5 are secured at their lower ends to the forward corners of the body 1, and their upper ends are rigidly supported by the posts 6 with the braces 7 Each of the beams 5 supports a rail 8 forming the track of the rigid section of the runway. Vertical sleeves 9 are secured near the two rear corners of the body 1, their upper portions being braced by thebraces 10. A bar 11, provided with a wheel 12 on its upper end, and a sheave 13 at its lower end, slides in each of the sleeves 9. Each of the sleeves 9 is provided with a hole 9a through which a lpin 141 is inserted for the bar 11 to rest upon when in the working position, Fig. 1.

The hinged portion of the inclined runway is composed of a frame 15 hinged by the hinges 16 to the upper ends of the posts 6, and is provided with rails 17 forming a track of the same gage as that of the rails 8.

The side beams of the frame 15 rest upon the wheels 12 on the bars 11, and in the working position these wheels 12 also engage the blocks 18 secured to the underside of the depending beams 15a of the frame 15. The

rails 17 are fastened to the upper surface of the side, beams of the frame 15, and at a point nearly above the wheels 12 they are bent downward so as to be approximately level when in the working position. The rear ends of these rails 17 are curved upward and the level portions are supported by the beams 15a as shown. Guides 19 are attached to each side of the frame 15, in

which a short rail 20 slides. The gage of the short track formed by the rails 20 is slightly wider than that of the rails 17. The upper ends of the rails 20 are also curved upward and their lower ends are each connected by a chain 21 to a tension spring 22 secured to the frame 15, Fig. 1. A brace 241 may be added at each side of the frame 15 with its lower end bolted to the top of sleeve 9, to further support said frame as shown in Fig. 1.

A pole 23 is provided 2) for transporting the apparatus by attaching horses to same.

A wire rope 25, with one end attached to the upper portion of the sleeve 9, passes downward around the sheave 13 and then upward and over a sheave 2G at the upper end of each sleeve 9. Each wire rope 25 is then led around a sheave 27 and wound upon a drum 28 to which the other ends of said ropes 25 are fastened. The drum 28 is journaled transversely upon the body 1, and

'is provided with a gear 29 meshing with the by the rails 8, is placed on the ground in front of the forward end of the body 1. A short inclined track 37 connects the ends of the rails 36 with the ends of the rails 8, to complete the runway, Fig. 1.

A carriage 39, for receiving, elevating and then dumping the load, is preferably made of two steel plates with bent up sides 40 and 41 hinged together and supported by the wheels 42 on the axles 43 and 44 attached to the telescoping sides of the longer plate 40. Said wheels 42 are adapted to run on the track formed by the rails 36, 37, 8 and 17 respectively of the runway. The axle 44 is provided with a wheel 45 on each end outside of the wheel 42. One end of a chain 46 is attached at 41a to the side of the plate 41 and the other end of said chain is linked to the block 47. A shorter similar chain 48 connects said block 47 and the side of the plate 40. A hinged brace with hook end 49 is hinged at 41b to the side of the plate 41, its hook end resting upon the piece 50 attached to the side of the plate 40. lVhen the plate 41 is swung upward on its hinges, the hook of the brace 49 slides rearward on said piece 50 and drops into a slot in same when the extreme upward position is reached shown in Figs. 1 and 2. The arrangement of the chains 46 48 block 47 brace 49 and piece 50 is similar on both sides of the carriage 39.

A druin shaft 55 is journaled in the boxes 56 transversely on the body 1, Fig. 3. A spur gear 58 and two flanged drums 57 are keyed to said shaft 55. A gasolene engine or other motor 59 is mounted upon the body 1 and connected by a friction clutch coupling 60, operated by a lever 61, to the shaft 62 journaled in the box 63. The shaft 62 is provided with a pinion 64, meshing with the gear 58, and with a brake-disk 65. A brakeband 66, operated by the lever 67, engages said disk 65. A wire rope is attached to each drum 57 and led around a sheave 71, in each crotch formed by the beams 5 and the body 1, and then upward and over a sheave 72 mounted at the upper end of the frame 15, thence over the block 47 of the carriage 39 and back to the rear of frame 15 to which the end of each rope 70 is secured.

A small sheave 75 and a U strap 76 on the end of a lever` 77, respectively engages and encircles each rope 70 in front of each drum 57, Fig. 3. The other end of each lever 77 is fitted on the upper squared end of a bolt 78 passing through a hole in a sill 2 of the body 1. A lever 79 is fitted on the lower squared end of said bolt 78 below said sill, Figs. 4 and 5. A rope or small chain 80, attached to a weight 81, passes over a sheave 82 and is fastened to the other end of the lever 79. rlhe end of said rope 80 is attached to a transverse piece 3 ofthe body 1,

so as to limit the movement of the leversy ,drums 57.

79 and 77 to the position shown by dotted lines in Fig. 4. The weight 81 shown consists of a piece of pipe with closed ends containing iron or lead balls, and is provided with two eyes 81aL for attaching the rope 80 at one end and a suspension hook 83 at the other end respectively.

A boom 85 is removably hinged to each corner of the rear end of the body 1. Each boom 85 is guyed by a rope 86, Fig. 1. An apron 87 is hinged at its upper end to the depending straps 88 bolted to the frame 15.

This apron 87 is partly supported, and its angle of slope adjusted, by means of the rope 89 over blocks 9() and 91 attached by chains 92 and 93 to the upper ends of the booms 85 and to the lower corneis of said apron 87 respectively.

The apparatus having been drawn by horses attached to the pole 23 and backed to the place of operation, the horses and said pole are removed therefrom. The booms 85 and apron 87 are shipped. The crank 32 is then operated, winding the ropes 25 onto the drum 28, and thereby raising the bars 11 in the sleeves 9, the wheels 12 rolling under and causing the frame 15 to swing upward on the hinges 16, until the wheel 12 engages the blocks 18. The pins 14 are then inserted in the holes 9a of the sleeves 9, supporting the bars 11. rlhe platform 35 is then placed on the ground directly in line with and in front of the body 1, with the inclined track 37 connecting the rails 36 on said platform with the. ends of the rails 8. The carriage 39 is now allowed to run down onto the platform 35, by allowing the ropes 70 to unwind from the drums 57. The braces 49 are then unhooked from the pieces 50 allowing the plate 41 to swing down and rest upon the platform 35. The motor 59 is started, and the slope or inclination of the apron 87 is adjusted by means of the tackle formed by the rope 89 and the blocks and 91. A dump cart or wagon containing the material to be loaded is backed upon the platform 35 and plate 41 and then dumped upon the carriage 39. The lever 61 is now operated, coupling the shaft 62 to the shaft of the motor 59, the pinion 64 and gear 58 causing the shaft to revolve and the ropes 7 O to wind upon the The weights 81, by the arrangement described, put suflicient pressure on the ropes 70 by the sheaves 75 to cause said ropes to coil evenly upon said drums, and not unevenly, or for example entirely 'at one end of a drum, as they otherwise would in leading` onto the drums from the sheaves 71. The ropes 70 being thus wound upon the drums 57, cause the blocks 47 to first pull on the chains 46, thereby swinging up the plate 41 on its hinges from the horizontal to the inclined position, the braces 49 sliding on the pieces 50 until they are hooked into same, whereupon the pull of the blocks a7 is divided between the chains t6 and 118 and the carriage 39 with its load is pulled up the runway, the wheels 4:2 rolling successively upon the rails 36, 37, S and 17. lt will be noted that in its inclined hooked position the plate L1 forms an end board to the carriage 39 and prevents material from dropping off same while going up thc incline of the runway.

Vhen the. carriage 89 arrives near the upper portion of the frame 15, the wheels 42 on the axles -13 run on the approximately level portions of the rails 17, while the wheels 45 on the axles 44e roll upon the short inclined rails 20, to cause the carriage 39 to tip so as to dump the load from same. The carriage continuing to be pulled by the ropes 70, the Wheels #l2 on the axles i3 soon engage the upwardly curved ends of the rails 1T, and the wheels A engage the similarly curved ends of the rails 20, the carriage then being in the position shown by dotted lines in Fig. 1. At the instant that this position is reached the lever 61 is operated to stop winding the ropes 70, and the brake 66 is tightened by means of the lever 67. Should however the operator be slow in the accomplishment of these operations, the ropes 70 will tip the carriage 39 up farther, the wheels 1-5 pulling the rails 20 sliding in the guides 19 against the act-ion of the spring 22. This arrangement provides a safety device and prevents the shock which would otherwise occur if the rails 20 were stationary. The material thus dumped from the carriage 39 falls upon the apron S7, from which it slides into a bin or onto a scow or otherwise as desired. By releasing the brake 66 the carriage is allowed to return by gravity to the position on the platfoi'm 35 for receiving the next load, and the operations as described are then repeated.
