Application filed September 4,1914. Serial No. 860,131. i
To all whom it may concem:
Be it known that I, SHERIDAN E. LAW, a citizen of the United States of America, re.-' siding at Toledo, Lucas county, Ohio, have invented a new and useful Unloading Device, of which the following is a specification.
This invention relates to mechanism for handling bulk 'material.
This invention has utility. when adapted for handling material from cars having hot.-
tom discharge openings.
Referring to the drawings: Figure 1 is a side 'elevation of an embodiment of the invention in an unloading device in'position as to a hopper bottom or discharge bottom opening railway car; Fig. 2 is a developed view of the driving gearing-for the device;
Fig. 3 is a fragmentary detail of mechanism interlocking with the railroad track rails and connected to deliver material to the elevator portion of the device; Fig. 4 is a plan of the mechanism of Fig. 3; Fig. 5. is a section on an enlarged scale on the line VV, F ig. 4'; and Fig. 6 is a section on'the. line VI-VI, 4, looking in the direction of the arrowi' r The truck or'frame 1 is mounted upon the rollers 2' and carries the prime mover, as internal-.- combustion-motor 3' having. the sprocket wheel 5 connected byvthe sprocket 1 chain 6-toact as a speed reducing drive-for the's'procket wheel 7 on the shaft 8, whichhas thereonthe bevel gear 9 (Fig. 2).

bevel gear 9 is inmesh with the pinion 10 on the shaft 11, which through the bevel gears-12,13, actuates the shaft 1A1 of the elevator, at the upper portion of the boom 15'011 the frame 1. Thisshaft- 14: drives the endless conveyer belt 16 sustained by the The mechanism for removing materialdischarged from'the bottom opening of a carjmay be brought into position to have" Specification of Letters Patent.
the gear 25 mesh with the gear 26 of the mechanism and thereby'actuate the shaft 27 carrying the roller 28 over which passes the conveyer belt 29, When the car30 on the rails 31 of the rallway track is spotted for being unloaded at a bin, say for removing coal, or atsome siding in the country for unloading road metal or other bulk material, the mechanism comprising the side frames 32 may be shoved under the bottom discharge opening of the car.- The wheels 33 allow the mechanism to be rolled into position for the notches 34, 35,- of the side frames 32 to engage with the rails 31. r
The endlessconveyer or belt 29 passes over the roller or belt pulley 36 on the shaft 37. On the shaft 37 are the supporting wheels or rollers 33 by which the device may be carried in thrusting into position across one rail of a track under the hopper bottom of a car. The lower reach of the belt 29 is sustained by the idler 38 to clear the nearer rail" 31. The idler 38 is mounted on the shaft 39. Connecting the shafts 27, 39,
are the links 40 which may be grasped by workmen in directing the mechanism into position beneath a car at any point along a right of way. Elements 41 extend from adjacent the shaft 27 engaging the elements 12 of the frame 1, to bring the gear 26 into mesh with the gear 25 and thereby readily bring the mechanism into disconnectible driving relation with the elevator portion of the device.
the mechanism to adapt itself to the position up or down of the elevator'as to thetrack.
The frames 32 (Fig. 5) are connected by the channel member 43 which may effectively sustain the load carrying reach of the belt in such instances as there might not be suflicient clearance for sustaining idlers 17 as used on the elevator.
When the mechanism is shoved into position under the car, and is connected up with the elevator for being driven therewith, be-
fore tripping the dump for discharging the car, it is well to place the plate sections or shields 44 in position over the belt 29 so that the great weight of material may not come down with such a great load upon the belt 29 as to stop the device or injuriously affect the belt. These sections 44: may accordingly afiord a simple adjusting means The link extension from the shaft of the roller 38 allows swinging of for regulating the supply of car discharged material handled by the mechanism. When the belt 29 has removed the material freely flowing thereon, the grip opening 45 in the section adjacent the elevator may be grasped and the section 44: withdrawn, and additional material will be supplied. The notches or seats provide oppositely directed faces engagingthe rails. The removal of sections may occur until all are taken out and the car is fully emptied. The mechanism by its belt 29 delivers by the chute 46 upon the elevator belt 16, if more than mere removal of material from under the car is desired, and the elevator may then handle as indicated.
The great capacity of dump cars makes them very difieultto unloadby hand over the top, andv availing of bottom discharge with special track elevation or excavated pits requires great yard outlay expense and special spotting or placing of cars in position. With the device herein disclosed a simple machine is produced which may be easily moved into position as to the spill of material to be handled, thereby providing a device having a great range of utility, Which device may permit a great saving of time and expense in car unloading.
What is claimed and it is desired to secure by Letters Patent is: v
1. A conveyer frame having a pair of parallel side members provided with downwardly projecting seats rigid therewith and disposed in opposing relation for resisting shifting of the frame by the conveyer in the line of the parallel side members, and removable load carrying strips extending be: tween the side members for receiving material to be handled by the conveyer, said loading of the strips holding the frame and 7 its seats in anchored posltion against shifting in conveyer operation.
2. A portable conveyer embodying a frame, supporting wheels for the frame, ,opposing downwardly projecting seats independent of the wheels and rigid with the frame, and independently removable strips on the frame for receiving material to be Lace tea handled by the conveyer, said loading of the strips holding the frame and its seats in anchoring position against shifting in conveyer operation.
3. A portable conveyer embodying a horizontally disposed parallel side member frame, a conveyer in the frame, carrying rollers for the frame, rigidly mounted axles in the frame for said rollers,'said axles being fixedly parallel, said frame being provided with opposing seats rigid with the frame and independent of the rollers for resisting shiftingv of the frame by the conveyer.
4. A portable conveyer embodying a horizontally disposed frame, supporting Wheels for the frame, and rail engaging seats rigid With the frame for locking the frame against travel and shifting when the conveyer is in operation in position transversely of a pair of rails and the frame seated to coact with the rails. I
5. A material handling device including an upwardly inclined conveyer, a first frame for the conveyer, a second horizontally disposed frame, a second conveyer, said second conveyer .carried by the second frame and embodying elements rigidly mounted on each of said frames, and adjustable connecting means movable out of the horizontal plane of the second frame for connecting the frames, said connecting means being in addition to the mounting of the second conveyer to the first frame. I
6. A material handling device including a first conveyer, a first frame therefor, a second horizontally disposed frame spaced from. the first frame, an adjustable connecting means movable out of the plane of the horizontal frame for connecting the frames, and a second conveyer carried by the two frames to deliver material to the first conveyer.
In testimony whereof I affix my signature in the presence of two witnesses.
