BROOKLYN, NEW YORK.

.CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. $93,442, dated February 1,?, 1884. Application filed June 12, 1853. (No model.)

To all wiz/om it may concern:

Be it known that I, CORNELIUS FLYNN, a citizen of the United States, residing in the city of Brooklyn, in the county of Kings and State of N ew York, have invented certain new and useful Improvements in Car-Couplings; and I hereby declare the following to `be a full, clear, and exact description thereof, reference being had to the accompanying drawings, which forni a part of this specification.

The object of this invention is to construct a carcoupler adapted to use the Ordinary coupling-link in such a manner that the several devices or mechanisms for coupling and uncoupling cars shall be automatic in their operations, and so that each shall act independently of the others and remain passive when not performing its particular function.

My present invention is more especially designed to be an improvement on a certain carcouplingfor which Letters Patent of the United States numbered 220,069 were granted to me September 30, 1879. In this improved carcoupling I retain and use the swinging frame described and claimed in the said Letters Patent, and my present improvements relate to the catch and other parts, as hereinafter particularly described; and this invention consistsin the improved constructions and combinations of parts, as hereinafter specifically described and claimed.

In` the accompanying drawings, Figure 1 represents a vertical longitudinal section of my improved car'coupler, taken through its center. Fig. 2 is an elevation of one of its sides, and Fig. 3 an elevation of itsopposite side. Fig. 4c is a front elevation of one-half of the coupler, and Fig. 5 a plan View of a device for operating the levers to free the link.

Similarletters of reference indicate the same parts in all the several iigures.

A represents the metal box in which the devices are held, which may be of suitable form and attached to the car in any suitable manner.

Bis the swinging frame, (above mentioned,)

to which is attached the swinging bolt B; and

Gis the loose weight which serves to retain the said frame and the bolt in position when the cars are coupled or uncoupled, as the case may be.

t is a plate secured to one arm of the frame B, against which the end of thelink E strikes when it enters the box, and thus brings the bolt B' into the position shown in Fig. l.

F is the catch which engages with the lowupon a shaft, a, which has bearings in the sides ofwthe box A, and is Operated by the levers b,- c, and d, the lever b beingv secured upon said shaft c. The end e of this catch, when in its normal position,'is held, as shown in Fig. l, to engage with the bolt B', the weight of the lever d tending to keep it in that position, and when said lever (l is raised the catch is lowered and disengaged from the bolt.

levend are inclosed within a box or compartment, f, the outer end ofthe lever d only being exposed.

f (which said plate is detachable) is removed to show the arrangement of the levers. When the lever d -is raised, said levers assume the positions shown by the dotted lines.

In Fig. 5 is shown a plan view of a device for operatingv the lever d. This consists of a shaft, g, which may be supported in any convenient position at the end of the car, (as for instance, underneath the platforn1,) upon which said shaft are fitted a fast pulley, 7L, and a loose pulley, 1i, and two hand-wheels, k la. A cord or chain, l, is attached at one end to the lever d and at its other end to the pulley 71 so that by turning either one of the handwheels k the coupling can be disengaged by a person when standing on the ground. Another cord or chain, Z, is attached to the loose pulley fi, and passed upward to the top of the car, lso that the coupling can be disengaged by a person when on the top of the car. Aclutch, m, is also secured to the shaft g, to engage with the projection on the loose pulley i, so that the movement of the latter is independent of that of the pulley h.

I is a hook or stop for steadying the link while the cars are being coupled. It is secured upon a shaft, n, that has bearings in the side of the box A, and is formed so as to press upon therear end of the link, (when brought into the position shown in Fig. 1,) and thus, in connection with an inclined plate or bar, o,

on the bottom ofthe box A, tends to depress the rear end of the link and correspondingly er end of the bolt B. This catch is secured The levers b and c and the forward end of the In the drawings the outer plate of the 4box IOO 2 :mama

raise the front end Of the saine, so that the latter is brought into'position to enter the Coupling-box of the ear, to be attaehed at about its center. This hook I is Operated by the levers p, q, and r, which are inelosed in a box or compartment7 L, the detachable front plate of Whieh is removed in the drawings in Order tO show the said levers. Apin, s, projecting through a slot in the front plate7 is provided on the upper end of the lever p, which is pushed forward to operate the levers by means of a hand-lever, t', that is pivoted to the box A or other suitable support in any convenient position. The under surface of the lever q, which comes in eontaet with the upper-.end of p, is formed substantially as shown in Fig. 3, so that the 'levers p, q, and o will be free to fall baek into the positions shown by the dotted lines in said figure whenever the pressure of the lever t is removed, and the hook I will then be released from the link and brought into the position shown by the dotted-lines I in Fig. l.

W'hat I elaiin as my invention isl. The levers I), c, and d, inelosed Within the box or compartment f and Operated as described7 in combination with the eateh F and swinging bolt B, as and for the purpose set Yforth fast pulley h, and loose pulley i, and hand- 4o wheels L lig-the whole being constructed as deseribed, to operate in the manner set forth.
