UN! STATES JOHN P. WALTER, OF ALLENTOWN, PENNSYLVANIA.

SHOVEL.

Application filed November 10, 1926. Serial No. 147,482.

This invention relateswhich is mainly designed for handling coal in mines but which, of con 1*, (an be used for handling other material, the general object of the invention being to so form the device that it can be used in restricted areas and in places where the head room is limited.

Another object of the invention is to provide means whereby tht shovel will cut mate rial from a hank or pile and deliver it to a transfer plate which will in turn deliver the material to a ronvevor, with means 011 the app 1, the transfer plate and the conveyor as well as to cause the entire apparatus to travel alon a surface.

A further object of the invcn n is to irovide a cutting device at one side oi, the shovel for cutting a straight wall at th s side of the apparatus.

Another object of the invention is to provide a rail with double flanged wheels on the apparatus for engaging the rail to keep the apparatus traveling in a strai ht line.

This invention also cons uction and in the combination and arrain cent of the se eral parts, to be hereinafter fully des r bed. illus 'itcd in the accompanying drawi. s and specifically pointed out in the appended claims.

In deecribing my invention in det. care will be had i-to the awon'ipanyi rawings wherein like characters denote like or corresponding part: throughout the several views,

which Figure l a plan view of the device.

l igure 2 is in elevation thereof.

Figure 3 a side view of the opposite side from that shown ir Figure 2.

Figure 4C is a front view.

Figure 5 is section on line 5 ure 1.

Figures 6, 7 and 8 are diagrammatic views showing the various positions of the rotary shovel and transfer plate during the operation of the device.

In these drawings 1 indicates the frame of the machine which at one side thereof is pro vided with the double flanged wheels 2 whi h are designed to run on the single rail track 3, the rest of the machine being so formed that it can slide over the surface upon which is traveling. The double flanged wheels, engaging the single rail, will cause the machine to travel in a straight line and prevent it from slewing around. Of course, both sides of the machine may be provided with wheels, if deto a power shovel features c f cons l, referand m sired, and the wheels may be so constructed that the device can travel on a track or they may be so made that the device need not be used with a track.

A rotary shovel 4 is arranged at the front of the machine and the said shovel comprises a hollow shaft 5 journaled in the frame and having a disk 6 at each end thereof and also having secured thereto the end spiders 7, which are arranged adjacent the disk and the central spider 8. A pair of plates 9 is secured to the spiders, the plates being secured to opposite sides of the spiders and extending in opposite directions with their outer portions curved to form the scoops 10, these scoop portions being provided with the teeth 11. Thus it will be seen that as the shovel rotates, the scoops wi ll engage material in front of the apparatus and separate some of it from the pile or bank and carry it upwardly and then toss it to the rear of the shovel where it will fall upon a tilting or transfer plate 12 which has its rear end fastened to a shaft 13 which is journaled in the frame. This plate, it is tilted upwardly, will discharge the material thereon upon a transversely extending conveyor 14 which will deliver the material to a point at one side of the apparatus. This COHVQyOF includes the endless belt 15 and the rollers 16 and 16 over which the belt passes, the ournals for the pintles of the shaft 16 being adjustable to take up slack in the belt, as shown at 17.

A shaft 18 is rotatably mounted in the hollow shaft 5 of the shovel and a cutter wheel 19 is connected to the right hand end of the said shaft 18, this wheel having the bits 20 on its periphery. A plow or mold board 21 is arranged at the opposite end of the rotary shovel for throwing material in front of the rotary shovel, this mold board being carried by a forwardly extending part 1 of the frame 1, which also carries the front wheel 2.

A. motor 22 is supported on the frame, this motor being shown as an electric one but it will, of course. be understood that it can be of any desired type. The shaft 23 of the motor is connected by the worm gearing 24 with a shaft journaled in the frame 1 and this shaft 25 is connected by the beveled gears 26 with a shaft 27 which has fastened thereto the sprockets 28 and 29. A chain 30 passes over the sprocket 28 and over a sprocket 31 which is connected with the hollow shaft 5 of the rotary shovel so that the shovel is rotated when the shaft 27 is rotated from the motor and a chain 32 passes over the sprocket 29 and over a sprocket 33 which is connected with the shaft 18 of the cutting wheel 19.

A shaft 34 is connected with the shaft 27 by the gears 35 and the said shaft 34 has a crank 36 at one end thereof which is connected by the connecting rod 3? with a crank 38 on the shaft 13 of the transfer plate so that said plate is tilted by the rocking movement of the shaft 13 through the rotary movement of the shaft 34 which is transmitted to the shaft 13 through the cranks and connecting rod. A shaft 39 is journalod in the apparatus and has a gear 46 thereon which meshes with the gear 35 on the shaft 34 and the said shaft 39 is connected to a pintle of the roller 16 of the conveying means by means of the beveled gears 41.

A clutch 42 is placed on the shaft 27 for connecting its gear 26 with the said shaft and the said clutch is operated from the rear of the machine through the shaft 4?; and the handle 44. Thus the rotary shovel, cat ter wheel, the transfer plate and the conveyor can be disconnecteo from the motor by moving the clutch to inoperative potion, but when the clutch is in operative position, tire rotary shovel and the cutter disk will be rotated, the transfer plate tilted and the cor.- veyor operated from the motor.

It will be seen that the cutter disk is entirely independent of the rotary shovel so that it can be driven at a different speed than that of'the shovel, the speed of the shovel and of the cutter disk being regulated by the sizes of the sprockets used for driving these parts. It will also be understood that where two scoops are used on the shovel, the material will be delivered to the transfer plate twice during each revolution of ti e shovel, so that it l be necessary to operate the plate twice for each revolution of thrshovel so that it will discharge the material received from one scoop upon the conveyor and then return to normal position to recel e the material from the second scoop and then discharge this and return to normal position to receive the material from the first scoop.

Any desired means may be used for propelling the apparatus. The drawings show a large sprocket. 45 and a small sprocket 4'8 on a shaft 47 which is driven from the shaft 25 through the we m gearing 48, clutch means 49 being provided for connecting the spro kets with the shaft. A chain 50 is adapted to be placed in engagement with either sprocket 45 or 46 according to the speed at which the apparatus to be moved, it being seen that the sprocket 46 is smaller than the sprocket 45 so that the apparatus would be moved at a slower speed if the chain is placed in the spr cket 46 instead of the sprocket 45. The chain passes over the idle sprockets 51 or and has its ends connected with anchor posts so that the chain is held stationary and as the 41' rotates, it will rotate the sprocket ha NHZSC the apparatus to move along 111 o c direction or the other accordo tire direction of rotation of the motor. a drum can be substituted for s and a cable substituted for the til in t 1 clutch 54 and this drum can be used for iving a cable for handling and other material and it can also be a power cal; drum.

oin it will be seen that 101' one chain or cab e has been anchored cad and in tl rear of the apparatus and the motor starts up and the clutches 42 and ii) H10". ed to operative position, the machine ill forwardly on the rail and into i to be loaded. As th shovel lupted to be connected with \fill pick up the material and de .011 the tilting plate which operates as the shovel, if the shovel i tvai scops and the said plate the material upon the conveyor which conveys it to one side of the ap ararus where t can be deposited upon cars or other vehicles or it can be deposited upon a second conveyor which will carry it to the rear of the machine. The shovel can be prov.:ded with but one scoop, if desired. Figures (2 and o show the manner in which the er plate operate to carry it the conveyor without the interfering with the movement of the cutter disk will operate to dress one renal side of the device. The plow I hand side acts to throw the ma- 1 L'oiit of the st ihis apparatus is mainly designed for use in coal mines where head room is limited. As is well known, the usual practice in such mines to make an undercut in the wall of Lhe coal. vein, after which holes are drilled near the roof of the vein to receive the powder so that the coal above the undercut is shot down. This usually leaves an arch which starts at the inner end of the undercut and extends to the roof of the vein, leaving a mass of material overhanging the undercut. This must be dressed straight before another out can be made. At this point the machine is brought into operation, the rotary shovel acting to tear down the overhanging mass of material, with the rotary disk cutter leaving a straight wall or face at the right hand side of the vein.
