WILLIAM '1. JONES, OF OMAR, WEST VIRGINIA.

LOADER.

Application filed November 21, 1922. Serial no. 602,402.

To all whom it may concern:

Be it known that I, WILLIAM T. JoNEs, a citizen of the United States, residing at Omar, in the county of Logan and State of t West Virginia, have invented certain new and useful Improvements in. Loaders, of which the following is aspecification.

This invention has special reference to means for loading coal into box cars, and

the primary object of the invention is to provide an apparatus by the use of which a greater tonna e than has heretofore been possible may be loaded into the car. The lnvention seeks to provide an apparatus which may be readily moved into or out of the car and which may be adjusted within the car so as to deposit the coal at either end of the same and at such height as may be most efficacious. The invention is illustrated in the accompanying drawings and will be hereinafter fully set forth.

In the drawings: Figure 1 is a side elevation, partlybroken away, of a loader embodyng my present improvements, and

, Fig. 2 is an end view of the same.

"In carrying out my present invention, I employ a truck conslsting of parallel side bars or sills 1 equipped at their centers with rollers or wheels 2 and at, their ends with casters 3. These sills are preferably constructed of angle steel, as will be readily understood u on reference to Fig. 2, and the casters 3 are fitted in suitable vertically disposed bearings at the ends of the sills, while the rollers 2 are carried by an axle 4 journaled in boxes 5 secured to the under sides of the sills. At the centers of the sills, I secure thereto standards 6 which preferably are constructed of angle bars and extending between the ends of the sills and the upper end of said standard are braces 7, the whole forming a triangular frame. The lower ends of the standard and the braces are reinforced and connected with the sills by gusset plates 8 so that a very strong and rigid structure is produced, and at the'upper ends of the triangular frame are secured journal boxes 9 receiving the ends of a fulcrum rod 10. ifhe upper ends of the braces and the upper end of the standard are also reinforced and connected by sset plates 11.

Fitted upon or secured to t e fulcrum rod 10 is the main loader frame which is disposed between the side frames of the truck.

and is adapted to rock about the fulcrum rod lO'as a center. The loader frame comprlses longitudinal beams 12 which are preferably steel channel bars, and to the said beams at the centers thereof are secured the bearlng plates 13 which depend below the beams and encircle the fulcrum rod, as will be readily understood. I also secure to the beams at the centers thereof the downwardly diverging hangers 14:, the lower ends of which carry a platform 15, upon which is mounted an electric motor 16 which may be of any reversible type and is illustrated in a conventional manner only. To aid in supportlng the platform 15 and to reinforce and impart rigidity to the loader frame, bracing struts 17 are secured to the ends of the platform and extend upwardly and outwardly therefrom to the sills where they are connected with the sills by gusset plates 18. Gusset plates 19 are-employed to connect the lower ends of the hangers 1 1 with the ends of the platform and the lower ends of the struts 17, as shown and as will be readily understood. Upon the beams 12, I secure a series of pedestals or hearing blocks 20 which extend longitudinally of the beams and support rollers 21. A conveyer belt or apron 22 is supported by the rollers 21 with its lower run extending below the rollers and between the beams, the bights of the said donveyer being, carried by drums or rollers 23 mounted at the ends of the beams, as clearly shown. One of the rollers or drums 23 is equipped at one end with a sprocket wheel 24, around which is trained a chain 25 passing to a sprocket wheel 26 which is carried by a countershaft 27, which countershaft also carries a pulley 28, around which is trained a belt 29 which transmits motion from a pulley 30 on the shaft of the motor 16. The countershaft 27 is journaled in bearings 31 carried by short beams 32 secured at their outer ends to the adjacent strut braces 17 and at their inner ends to posts or standards 33 which extend between the platform 15 and the beams 12, as clearly shown. Gusset plates 34 are employed to connect the several elements at their meet-=- ing points so that a ver strong and rigid structure will result. t intervals along the beams 12, ll secure the posts or upstanding brackets 35, and to the upper ends of said posts or brackets are secured the long; tudinally extending guard. rails 36.

shown most clearly in Fig. 2, these guard rails are disposed in inclined positions with their lower edges projecting over the side edges of the conveyer 22 so that the coal delivered onto the conveyer will be prevented from passing over the sides of the same. That guard rail which is at the far side of the loader is provided with a vertical extension 37 so that it will project up into the path of the coal delivered from the tipple or storage bin and will deflect the coal back onto the conveyor instead of permitting it to pass beyond the conveyer and possibly be lost.

Upon that side of the truck remote from the countershaft 27, I secure the brackets 38 which project outwardly from the truckand support a shaft 39 extending across the loader. Upon the saidshaft adjacent the ends thereof are secured pinions 40 which mesh with racks 41 upon the sides of the loader frame, the said racks being formed on I arcs concentric with the fulcrum rod 10, as

clearly shown in Fig. 1. One end of the shaft 39 is constructed to be engaged by a crank or other turning tool 42 so that the said shaft may be rotated when desired. The loader is well balanced so that, ordinarily, it will remain in the position in which it is set by the operation of the pinion 40 and rack 42. If, however, it should seem advisable, any convenient means (not shown) may be employed to engage the turning handle 42 and thereby hold the parts against movement.

My loader is designed to be used in con nection with a storage bin or tipple erected at the side of a railroad track, the loader being moved from the tipple platform into the car to be loaded and, of course, removed from the car onto the platform after the loading has been accomplished. The loader is of such form and dimensions that it may be easily pushed through the door of the car and assume a position longitudinally of the car with one end under the chute of the tipple or storage bin. The motor is then started so asto effect travel of the upper run of the conveyer 22 from-the end disposed under the tipple chute and the trap door or gate of the tipple is opened so that the coal may pass through the chute onto the con-- veyer. The coal delivered onto the conveyer will be obviously carried by the same to the end of the car and will be deposited therein.

As the loading progresses, the delivery end of the conveyer may be raised by proper manipulation of the handle 42 so that the rotation of the pinion 40 will elfect upward movement of the rack bar 41 and consequently tilt the loader frame about the fulcrum rod 10. When one end of the car has been loaded, the loader is shifted toward the opposite. end of the car and the motor reversed so that the coal will be stored at the second end of the car. lVhen both ends have been loaded to capacity, the loader is withdrawn and the coal from the tipple chute may then be permitted to run directly into the car so as to fill the center of the same. By this operation, I am enabled to more fully load the car than has been heretofore possible without employing manual labor which is slow and costly. My improved loader is very simple in the construction and arrangement of its parts, is strong and durable and may be easily adjusted so as to regulate the height at which the coal will be deposited within the car.

Having thus described the invention, what is claimed as new is:

A loader comprising a truck and a loader frame mounted to oscillate on the truck,

through the axis of oscillation; said truck including a wheeled base, a pair of checks rigidly mounted upon said base, said cheeks being of triangular shape and made of structural material terminating at the apex with bearing elements; said frame being also constructed of structural material in the shape of two pairs of inverted triangles having common bases formed of straight beams, trunnions secured on said beams at the junction of said triangles, and a platform connecting the apexes of said triangles, a motor mounted upon "said platform, rollers revolubly mounted upon said straight beams, an endless belt engaging said rollers, and inclined longitudinal guide members forming a trough with said belt as a bottom, and secured upon said straight beams; suitable gearing between said motor and said rollers,
