DENNIS P. EDGAR, OF JACKSON, MICHIGAN.
CAR-COUPLING.
SPECIFICATION forming part of Letters Patent No. 311,651, dated.;Eebruary 3, 1885.
Application filed September 24, 1884.
To all whom it may concern.-
Be it known that I, DENNIS P. EDGAR, residing at Jackson, in the county of Jackson and State of Michigan, have invented an Automatic Car-Coupling, of which the following is aspecification.
The special object of the invention is toimprove that class of car-couplings in which the pin is supported by a spring-slide adapted to drop the pin when two cars come together.
Figure l of the drawings is a perspective view showing a draw-head with lateral studs near the rear end, a front link-support laterally pivoted, and a pin-support extending through both ends, the latter being connected with operative mechanism. Fig. 2 is a longitndinal section with a view of the relative position of the parts when the car is not coupled to another. Fig. 3 is a horizontal view, partly in section, to show the inside of the boxes and the position of the rubbers which take the shock. Fig. 4c is a side elevation partly broken away to show a modified construction. Fig. 5 is a perspective view of the said modification.
I11 the drawings, A represents a draw-head having the side studs, a, which work in holes I) b of the boxes B B and carry rubbers O G, which serve to take the shock in both direc tions, while the draft-strain is taken by the solid metal.
D is the pin-support slide, which is held forward by a spring, E, so as to sustain the pin until moved back by the coming together of two cars.
As thus broadly stated, the device is very old; but I make the slot (1 large enough in front to let the pin-head through it, at the rear so small as to allow the side walls of slot to work in groove f of the pin, so that the latter cannot be jolted out, and intermediately I make the slot large enough to allow the pinshank to pass through, but not the head. This permits cars to be uncoupled in case of derailment or other accident by simply pulling the slide at its rear end, and this may be done from the top or platform without the passage of the brakeman between the cars.
In order to provide for the rear movement of the slide, I connect its rear end by a chain, G, with a pulley, H, made fast upon a shaft or rod, I.
(No model J represents an angular link-support with one pivoted arm arranged to slide in a hole,
a, of the draw-head, a stop, a, being arranged,
011 the link-support to prevent it from being drawn out altogether. The side arm of the link-support rests upon a flat spring, K, as shown in Fig. 4 of the drawings, and is held up when the link is to be sustained, but at other times is allowed to hang down at the side. This link-support is adapted to draw-heads of varying heights. On the upper edge of the link-supporting arm I erect a median vertical stud, it, and preferably,but not necessarily,one at each side, so that the middle one will pass up into the slot of the link, while one of the others will stand on each side of it. This insures the link against lateral displacement. A crooked link may be used, if desired.
It will be perceived that with my invention the uncoupling may be done without stopping the cars and from any direction, while it may be used with the old link-and-pin system.
What I desire to protect by Letters Patent 1s- 1. The combination, with a draw-head having side studs, a, of car-boxes B, provided with two rubbers, O O, in each box, and arranged to take both the back and forward shock, as set forth. V
2. In car-couplings,the pin-supporting slide made with a slot, at, contracted at the rear to have its sides work in groove f of the pin, and thence toward the front sufficiently enlarged to allow the shank but not the head of pin to pass through, the slide thus moving back over the pinshank and catching the pin-head, as described.
3. The combination,with a pin-support pro vided with an opening sufficiently large to let the pin drop entirely through it, of a drawhead having a vertically-apertured trap, L,
arranged to let the shank pass through but to catch the head, substantially as described.
4. A car-coupling draw-head provided with] 7. The combination, with the pivot-arm of asubjacent tI'a-p, L, having a vertical hole, Z, the link-support J, of a spring arranged bea front hole, Z,- and a rear open slot, Zflwhere neath said arm, so as to hold said support in by the pin may be removed, as described. whatever position it may be placed, as set I 5 5. In car-couplers, the angular link-sup forth. 7
port J,v pivoted by one arm to turn downat the side, as and for the purpose set forth.
6. In car-couplings, a link-support pivoted to turn transversely in a vertical plane and VVitnesse's:
10 provided with a median stud onits upper side JAMES CooKBURN,
adapted to enter the link, as set forth. I DELANA COCKBURN.
