CAR-COUPLING.

SPECIFICATION formingvpart'of Letters Patent No. 351,754, dated November 2, 1886. i Application'led August 21, 18H6. Serial No. 2ll.543. (hic model.)

To MZ whom, it may concern:

Be it known that I, JOHN H. EARLEs, a citi` zen of the United States, residing at Denver, in the county of Arapahoe and State ot' Colorado, have invented a new and useful Improve ment in Oar-Couplings, of' which the following is a specification. v

My invention relates to improvements in car-couplings; and the object of my improvements is to provide a railway car-coupling which shall be simple, durable, practicable, and automatic. I attain this object' by means of the mechanism illustrated in the accompanying drawings, in whichv Figure 1 is a side elevation of my improved device as thesame would appear attached to the end of a ear, the pin being down and the link in the draw-head. Fig. 2 is a side elevation of my improved coupling, showing the pin uprased. Fig. 3 is .a top viewof my coupling. Fig. 4 is a top view showing a longitudinal section of the draw-head. Fig. 5 is an elevated section of the draw-head, showing also the pin, trigger, and link, the link being about to enter the draw-head. Fig. 6 is an edge view of the pin and trigger, the trigger being raised. Fig. 7 is a side view of the pin.V

Fig. 8 is a view ol' spring, by means of which the pin is kept raised, thus preventing the coupling from acting when the link enters the draw-head.

In the drawings, a a are two levers, attached to the end of the car by bolts a and clasps a2.

. Said bolts form the fulcrums ot' the levers.

The clasps are riveted or securely bolted to the car. Levers c c are of sufcient length to permit of their being operated without going between the cars. The inner extremities of levers a a contain the slots a?.

b is the pin, shaped as shown in the drawings. The upper extremity of pin b is provided with a lug, b', containing a hole. The pin is attached to levers a by means of a bolt, c, which passes through the hole .in lug b', also through the slots c3 in levers c. Levers@ also contain slots a4, as shown in Fig. 3. Slots a4 are cut at right angles to slot-s as. The manner of uniting the inner extremities of the levers when the pin is attached is shown in Fig. 3. Slots c3 are large enough, so that they move easily longitudinally upon bolt c. To the lower portion of pin b is attached the trigger d by means of the rivet d'. Trigger d moves easily upon the rivet.

e is the ordinary draw-head with some modiieations. The hole c is made larger, as the pin b is wider than the old-fashioned couplingpins. The bottom of the insideportion of t-he draw-head is cut out so as to form a slight depression, e2. (Shown in Figs. 4 and 5.) The object ot' depression e2 is to allow the inner extremityof the link to fall, so as to raise the outer extremity suitciently for all practical purposes. AThis adjustment of the link is made by the use of levers a. The portion ofthe pin marked b`l rests upon the link when the pin is down. By raising the outer extremity ot' either lever a the inner extremity ofthe link is forced downward into depression e2. Pin b may also be adjusted from the top of car by use of a suitable rod or lever. The lower extremity of the trigger when set Vrests in the rear portion ot' depression ci. ciently large to allow the trigger to revolve freely upon rivet el.

j' is a metal bar the extremities of which are bolted to the end of the car, the central portion being bowed up so as to leave a small space underneath, as shown'in Fig. S.

g is aspring, with the lower extremity turned outward so as to form a hook,as shown. The upper extremity of spring g is riveted to bar f.

lL is a movable slide or ring surrounding spring g and barf, and may occupy any position on spring g below its fastening-rivet. Vhen slide h is near the lower extremity of the spring, as shown in the drawings, the spring is held close to the bar f throughout its length. It is held in this position when not in use. Its use is ,to hold the levers a in such aposition as to keep the pin b elevated when the link enters the draw-head, when it is not desired that the coupling should oper-v ate. The position of spring g when in use, and also of clasp h when the spring is in-.use, is shown by dotted lines in Fig. 8. The levers a, each contain a hole, g', to receive the hooked extremity of spring g. The spring g is so placed that levers a must be forced down slightly in order that hook gt may enter the hole g'. This slight downward pressure elevates the pin sufficiently to allow the link to The opening is sufli- ICO enter the draw-head and pass out without resistance, the trigger simply swinging back and forth but not catching the link.

In the operation ot' my improved coupling the pin b is raised by the use of levers a until the lower extremity ofthe trigger will rest in the rear portion ofthe depression ci in bottom of the draw-head, standing with a slight inclination, as shown in Fig. 5. The pin b is raised in a vertical position by virtue of the slots a. The coupling is then ready for use. As the link enters the draw-head it causes the trigger d to turn upon its rivet d', as shown in Fig. 6. The pin then drops through the link, as shown in Fig. 1, and the cars are coupled.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, l

sips

l. In a car-coupling, the combination of levers a, attached to car by bolts d, which form their fulcrums, said levers being provided .with slots a, bolt c, pin b, trigger (l, and a suitable draw-head, substantially as described, and for the purpose set forth.

2. In a car-coupling, the combination of levers a, provided wit-h slots a and a and holes a, suitable fulcrums, a', bolt c, piu 71, and a suitable draw-head, substantially as described.

3. In a car-coupling, levers a, provided with slots a and holes a, suitable i'ulcrunis, a', bolt 3o c, pin b, a suitable draw-head, spring g, clasp h, and bar f, substantially as described.
