CAB-UNLOADING APPARATUS.

. Specification of Letters Patent.

Patented May 15, 1917.

Appli-cation filed February 23, 1916. Serial No. 80,023.

To all whom t 'majz/ concern Beit known that I, EDWIN DUVALL, a citizen of the United States of America, residing at Sharonville, inthe county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Car-Unloading Apparatus, of which the following is a specification, reference. being had therein to the accompanying drawing.

This invention relates to a car unloading apparatus and has for its object the producy parts, as will be hereinafter fully described and claimed. 1

In the accompanying drawings Figure 1 is a' top plan view of the apparatus.

Fig. 2 is a side elevation of the drum used in connection with the present invention.

Fig. 3 is a central vertical section through the drum. l

Fig. 4 is a section taken on lineflof Fig.

Fig. 5 is a central transverse section through the drum, showing the same in an inverted position.

Fig. 6 is 'a diagrammatic view, showing the manner of rotating the drum upon the supporting tracks. l n y Fig. 7 is a vertical section through one of the car engaging beams carried by the inner frame of the drum.

Fig. 8 is a section taken on line 8 8 of Fig. 7.

Fig. 9 is an enlarged longitudinal section through' the base platform of the inner frameof the drum.

Fig. 1() is an enlarged section showing the manner of attaching the anchoring or operating cable which is adapted to cause the drum to travel upon the supporting tracks.

Referring to the accompanying drawings by numerals it will beseen that 1 designates the main or-supporting trestle-work which comprises a plurality of transversely extending ties 2 upon which ties 2 are mounted the side rails 3 and the central rail 4. By carefully considering Fig. l, it will be seen that the side rails 3 are arranged in pairs and are adapted to receive the circumferentially extending channel irons 5 carried by the drum 6. This drum 6 extends entirely across the trestle-worlrland has one end thereof working upon the opposite pairs of supporting rails 8 as clearly illustrated in Fig. 1 of the drawings. Upon a careful consideration of Fig. 1 of the drawings, it-

will he seen that the channel plates 5 are arranged in close proximity to each other adjacent the terminal ends of the drum 6. A secondary arrangedchannel plate 7 is carried intermediate the ends of the drum as illustrated in Fig. 1 and this plate 7 is adapted to travel upon the centrally located rail 4.

By carefully considering Figs. 3 and 5 of the drawings, it will be seen that these channel irons 5 and 7 extend around the outer ners for traveling uponl the respective rails 3 and 4.

An inner frame-work 8 is` mounted within the drum 6 and comprises a plurality of beams which are so arranged as toconstitute a square housing in cross section as illustrated in Fig. 3. bracing beams 9 are carried by the inner frame 8 and a covering or lining plate 10 is fitted. upon the inner face oi` vhe car bracing beams 9. The inner drum 8 is also provided with a lining 11,0f suitable construction, such for instance as sheet metal, or any other convenient material which may he found advisable. The frame Sxfis provided with a chute portion 12, which chute portion 12 communicates with a plurality of elongated slots lformed in the upper portion of the drum 6. i

The base portion 14 of the frame 8 is provided with a plurality of spaced rails 15 for the purpose of permitting the car 16 to travel into the drum 6 and upon the rails 15 from the trackways 17 communicating with the rails'l.

A plurality of eyes 18 are secured to the bottom platform 14 and a plurality of chains 19 are secured to the eyes 18 and are pro- A plurality of car.

vided with hooks 20 for the purpose of fitting over the upper or outer edges of the car 16, as clearly illustrated in Fig. 3 of the plates 5 upon the respective ends of thel drawi gs.

A bracing plate 21 is carried by thelining 10v and is provided with a substantially V-shaped channel groove 22 upon the outer edge thereof for the purpose of receiving the lower corner of the car frame or body 16, as clearly illustrated in Fig. 3 of the drawings. An abutment block 2 3 is slidably mounted upon the bracing beam 9 and is adapted to engage the side of the car 16 and constitute a brace or support therefor, while the drum 6 is being rotated, in one direction. A plurality of supporting bolts 24 are carried by the beam 23 and these bolts 24 pass throughthe elongated slots 25 formed in the beams 9, as illustrated' clearly in Figs. 7 and 8 of the drawings. It of course should be understood that the beam.

2321s well as the plate 21 is provided with notched portions 26 for the purpose of permitting 'the chains 19 to pass therethrough and remain in ataut position.

' By carefully considering Fig. 1 of the drawings, it will be seen that the channel drum 6 are placed at a suiiicient distance apart to ermit the operating cables 27 to pass there etween for-the purpose of operating t-he rotating drum 6. The cables 27 are anchored by means of an anchor member 28 -as illustrated in Fig. 10 in any desired position as for instance upon one ,side of the discharge pit 29. It should be understood that the discharge pit 29 is. placed below4 the track or trestle-work 1 and so arranged as to have the rails 3 and 4 extend over the pit 29, thereby permitting the material carried Vby the car -16 to be emptied into a car 16,

adapted to -be placed within the pit 29.

A suitable windlass 30 is mounted in any desired position adjacent the track or trestle-work 1 and the cable 27 is wound upon the Windlass 30 as illustrated in diagram in Fig. 6, the cable first passing around the drum 6 for one complete revolution between the channel plates 5 carried upon the ends in Fig. 1 and a car loaded with coal, broken stone, or other material, is run into the hol- ',.low drum 6 upon the rails 15 and is then anchored in a set position by means of the chains 19. After the car has been placed in a set position, the windlass 30 is operated s o as to wind the cable 2 7V thereon and cause the `drurn 6 to move in the direction of the arrow indicated in Fig. 6 of the drawings. After the drum 6 has made one halfv a revolution and been drawn to the position shown in Fig. 5, the materialwithin the car 16 will be discharged out through the discharge chute 12 and cause thematerial from the car 16 to be deposited into the car 16 positionedwithin the vpit 29, upon the rails 31.

After the windlass 30 has been released, however, the drum 6 will return to its normal position through the force of gravity in view of the fact that the rails 3 and 4 are inclined downwardly away from the windlass 30. v

What 'I claim is In a car dumping machine, the combina- 'tion with a maincylinder, a frame posia car body for bracingjhe samewhile dumping and assisting in holding said car body against displacement.

In testimony whereof I hereunto aiix my signature.
