Specification of Letters Patent. t t June 21, 1 21 Application filed November 17, 1917. Serial No. 202,476.

To allwhomz'tmay concern:

Be it known that I, SPASOJE Josnrn KRULY, a citizen of the United States, and a resident of Miami, in the county of Gila and State of Arizona, have invented certain new and useful Improvements in Shoveling- Machines, of which the following is a speci fication.

My invention is an improvement in shoveling machines, and has for its object to provide mechanism of the character specified for shoveling ore, dirt and the like, whereina supporting platform is provided, having an inclined track on which the shovel runs, thecar carrying a ram for loading the shovel, and power operated means for raising the shovel, the platform being mounted on a carand adjustable with respect to the car, and the operating means for the shovel being connected to the plat form and to the car to control the movement of the platform and of the car.

In the drawings:

Figure 1 is a. side view of the improved machine; ,7

Fig. 2 is an enlarged longitudinal section;

Fig. 3 is a top plan view;

Fig. 4; is a section on the line Ar-tl: of Fig. 3, lookingin the direction of the arrows adjacent the line;

Fig. 5 is an enlarged detail sectional view of a portion of Fig. 4;

Fig. 6 is a perspective view of a portion of the clutch shown in Figs. 4 and 5;

Fig. 7 is a perspective view of the shovel or dipper.

In the present embodiment of the invention a table or platform 1 is provided, which is provided with pairs of uprights or standards 2 and 3 near its ends, and the table is mounted on the body 4L of a car, which is provided with wheels 5 mounted on axles 6 and adapted to engage a track 7 upon which the car runs.

It. will benoticed that the table extends beyond the front of the car, and rollers 8 are journaled on the table, and the said rollers run upon arch shaped tracks 9 on the car body. The pairs of standards 2 and 3 support rails 10,'the said rails being connected together'in spaced relationby cross bars 11 to, form a track upon whichi the shovel or dipper, to .be described, runs. These rails dip down at the forward end of the car, as shown in Fig. 1, to the level of the rails in order that the dipper may be filled at this point and run to dumping position at the uprights 3. 7

At their rear ends the rails have clownwardly curved dipsor extensions 12, and these extensions are adapted to receive the rear wheels of the bucket to .tilt' the same in order to discharge the load. A chute 13 is supported by standards 14 at the rear of the car, and into this chute the material is dumped by the bucket or dipper.

Referring to Figs. 1 and 2, it will be noticed that each standard 2 and-3 has a verticalgroove 15 on itsinner face, and the grooves of each pair of standards are en.- gaged by the ends of rollers 16, the rollers supporting the track. These rollers are com nected to the pistons of cylinders 17,. ar-

ranged betweenthe standards, audit. will be evident that by means of the cylinders the 1 the rails, and the bucket ordipper has a :cut-

ting shoe 20 at its open front. The rear of the dipper closedby a door 21 which is hinged at 22 to the dipper, andthis door is held closed by latch plates 23 pivoted to the 1 door and engaging catches 24 on the body of the dipper. The front and the top ofthe bucket are closed by a door or gate 25 which has bearings 26 squared in cross section for engaging similarly shaped portionslvof a shaft 27 journaled on the top. This-door or gate 25 extends from its hinge connectionto the cutting shoe 2(), asindicated in Fig. 2 This shaft has a depending arm 28' at each to which the bail 3O of'the bucket is connected. l Vhen the bucket or dipper is drawn by the bail rearwardly, it will be evident that the pull on the bail. will close'the door end, and these arms are pivoted to link 29 at 25 and hold it tightly closed. The links 29 i around a pulley 34 journaled on the crossbar 35 supported by the standards 3 and spaced rearwardly therefrom by holding plates 36. From the pulley 34 the cable passes outwardly around a pulley 37 journaled on one of the plates 36 and then forwardlyover a pulley 38 on the adjacent standard. The cable passes forwardly from this pulley 38 over a pulley 39, and then passes rearwardly over a pulley'40 near the rear standards to a reel 41 upon which it winds, the said reel being supported by the table.

The reel is journaled on a shaft 42, and r of a rope or cable 25 which 1s connected to 90 may be connected to the shaft by means of a clutch 43. The reel is driven by a fluid controlled motor 44, the piston of the motor being connected to the reel, as indicated at 45, and it will be evident that when the motor is in operation the reel will be rotated to wind up the cable. The weight of the dipper will unwind the cable from the reel when the dipper descends. The shaft 42 is connected with the front wheels of the car, and with the car and table in such manner that it may shift the car on the track and the table on the car.

A shaft 46 is journaled vertically in bear-- A disk 54 is mounted to slide vertically on the bearing 47, and this disk has a series of depending pins 55, and bearing 47 as shown, has a web through which the pins extend, and the upper face of the disk has clutch teeth, as shown in Fig. 6, which are adapted to engage similar teeth on the lower face of the bevel gear 49. The disk is raised and lowered by means of a lever 56, and when it is raised to engage the clutch teeth with those of the bevel pinion 49, movement of the shaft 42 will rotate the platform on the shaft 47 as acenter. Thus the table or platform may be'swung from side to side, as in trench work.

i The bucket or dipper is filled by means of a ram indicated at 57, and this ram, the rams 17 and the motor 44 are supplied with fluid under pressure, as, for instance, air or water from reservoirs 58 which are supported on the table.

In operation,with the parts in the position of Fig. 2, the reel is released from the shaft 42 and the bucket is permitted to run down to the position of Fig. 1. At this point the ram 57 comes into operation, pushing the bucket or dipper into the material to be shoveled. When the bucket is filled the reel 41 is clutched to the shaft 42 and the bucket is drawn into the position of-Fig. 2.

The rear wheels of the bucket drop into the depressions of the extensions '7 and. at the same moment trips 12 in the form ofupwardly curved portions at the rear ends of the extensions engage the latches 23, releasing them from the catches 24 and permitan extension 28 from one of the elements 28. This rope is handled by the operator of the machine. After the door is initially opened the entering ore will keep it open until it is closed and clamped shut by the upward movement of the bucket. In order to start the bucket or dipper downwardly after dumpin the operator will raise the rearmost shafi 16 or lower the front shaft 16 or combine the two operations to impart V a suflicient inclination to the track 10 to cause the bucket or dipper to move down the incline. The tilting of the track is under the control of the operator. 1 l
