IMPROVED Mons or FASTENING rmrnsrsnmc DROP-DOORS n COAL aims.
WILLIAM BURT, OF MAR ETT MIG IGAN, Y Letters Patent No. 60,340, dated December 11, 1866.
narttfttmam. I
TO ALL WHOM IT MAY CONCERN:
Be it known that I, WILLIAM BURT, of Marquette, in the county of Marquette, in the State of Michigan, t, have invented a new and useful Improvement for Fastening and Unfastening the Drop-Doors of Ore and Coal Cars; and I do hereby declare that the following is a full, clear, and exact description of the construction and E operation of the same, reference being had to the annexed drawings making a part of this specification, in 1,
which- Figurel is a vertical section of ore vtor coal car.
Figure 2 is a plan of that part of the car essential to a proper understanding of the working of the drop 1 doors in connection with my improvement.
' In the drawings, the car frame is shown at G, the drop-doors a, eye-pins P, lever or bar- B, hole through bar 0:, cam shafts L, cams c, hinges h, hole through car frame 'n. In general, I makethe lever or bar and eye-f pin of wrought iron.
The drop-doors, a, are shut by lifting them to their places, as in fig. 2, and turning the lever or bar, B, so i 1 v, 3 as to bring the earns, a, in contact with the under side of the drop-doors, and then fastening the lever or bar by, inserting the'eye-pin, P, through the hole, 2:, and the car frame at n, inclining the point downward, which, by its gravity, retains its place and thus secures the drop-doors from falling. The drop-doors are opened by simply withdrawing the eye-pin, P, as in fig. 1.
I do not claim fastening the drop-doors of ore or coal cars by means of ratchet-wheels and catches, neither 1 i do I claim the slotted wheels and pins, both of said methods being old and objectionable on account of the I breaking of the catches and ratchet-wheels and the pressing ofi of these wheels by the oarsides, thusvcausing the doors to fall with their loads, andconsequently the blocking of the drop-doors atthe mines.
' What I claim as my improvement is t The combination of the lever B, shaft L, cams 0, attached to the said shafts L, pins P, with the drop-doors a, when the same are constructed and arranged in the manner and for the purpose set forth.
