CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 551,249, dated December 10, 1895.

Application filed October 5,1895. Serial No. 564,705. (No model.)

To all whom it may concern:

Be it known that I, ALEXANDER ATKINSON, a citizen of the United States of America', residing at l-Iuntsville, in the countyof Madison and State of Alabama, have invented certain new and useful Improvements in Car- Gonplings; and l do hereby declare the following to be a full, clear, and exact description of the invention, sue-h as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of this invention is to provide an improved car-coupling which is adapted to be used in connection with a coupling-link of the arrow-head type.

The invention consists in providing the coupling-head with two pivoted plates between which the head of the coupling-link passes to engage therewith, the pivoted plates being spring-actuated and held again st swinging movement in one direction by iiat springs having lugs with which the plates engage, means being provided for throwing the flat springs out of engagementwith the plates.

The invention further consists in the particular construction and combination of the parts, as will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure l is a perspective view of the coupling mechanism constructed in accordance with my invention. Fig. 2 is a longitudinal sectional View, and Fig. 3 is a horizontal sectional view, showing the two coupling-heads, one having the coupling mechanism and the other the couplinglinlc. Fig. fi is a detail View of the brace-plate.

A designates the coupling-head which is connected to the car in the usual manner and consists of side pieces A connected to each other by cross-pieces A2, A3 and A4, the crosspieces A3 forming the top of the couplinghead. p

B B designate coupling-plates which are centrally attached to vertical shafts b journaled in the cross-pieces A2 and AB of the i coupling-head, and to the upper end of the shafts are rigidiysecured rearwardly-projecting plates li' having lugs b2 at their rear ends with which springs c and c engage to hold the coupling-plates B normally at right angles with the side pieces A of the couplinghead. The springs c and c' are attached to the top A3 of the coupling-head and are provided with coils, as shown. To the top A3 are secured pins c2 which limit the movement of the springs c in one direction, and a bail or loop c3 which limits the move-nient of the springs o.

D D designate brace-plates which are provided with diverging members d d apertured to iit over the upper end of the vertical shafts 19 to which the coupling-plates are attached,

' one of the brace-plates being located below the top of the coupling-head While the other is a considerable distance above the same, as

shown more clearly in Fig. 2. The rear ends of the brace-plates are rigidlyv secured to the coupling-head by a bolt d which passes through the top A3, cross-piece AL and inter posed block d2.

E E designate flat spring bars which are located within the coupling-head and are connected to the side pieces thereof by means of screws or bolts e. and e, being connected to each other by a cross-piece e2 into which the screws e pass. The rear ends of the bars E are bent upon the cross-piece e2 and also bear against the cross-piece A to further brace the saine against rearward movement.

Near the forward end of each bar E and on the inner side thereof is formed a lug E', and with these lugs the outer ends of the couplingplates B engage to prevent the inner ends from swinging outwardly when the cars are coupled, the coupling-link engaging said inner ends, as hereinafter set forth. The upperpart of the forward end of each dat springbar E is bent outwardly, as shown at E2, and upon the coupling-head is mounted a roel;- shaft F, having projecting arms ff, which engage the curved surfaces E2 and force the spring-bars out of engagement with the coupling-plates. The ends of the rock-shaft F eX- tend a considerable distance on either side of the coupling -head and are provided with crank-handles, so that said shaft can be operated from either side of the car,

In order to operate the flat spring-bars E from the top of the car, I provide two vertical shafts G and G', which are journaled in the top and bottom pieces of the couplinghead, and are provided with projecting portions or lugs G2, which are adapted to bear against the bars E to move them to one side. The shafts G and G are connected to each other by a connecting-rod g, which is connected to arms projecting from the upper ends of said shafts, so that they will be turned in unison. One of the shafts is extended to the top of the car, where it is provided with a crank-handle for operating the same. Upon the coupling-head is attached a spring-catch 71, which engages a projecting portion on one of the shafts to hold the spring-bars E out of engagement with the coupling-plates to permit the coupling-link to be withdrawn.

I designates the coupling-link, which is provided with a head 1', the forward end of which is rounded, and t-his coupling-link is pivoted to its coupling-head so as to have a limited horizontal swinging movement, being provided with springs fz which impinge against the adjacent edges k of the coupling-head, the link being cut away adjoining the springs, as shown.

This invention provides an efficient automatic car-coupling having means for uncoupling the cars from the sides and top thereof and means for holding` the spring-bars so that the coupling-plates will be allowed to swing freely and permit the insertion and withdrawal of the coupling-link when it is not desired to couple the cars when they come together. It will be noted that the couplinglink can enter the coupling-head, so that the heads will abut and the shock incident to the cars coming together will not be thrown on the coupling' mechanism.

Having thus described my invention., what I claim as new, and desire to secure by Letters Patent, is-

1. In a car-coupling, the combination with a coupling-head, of swinging plates B mounted therein upon vertical axes, springs for holding the plates normally on a line with each other, and flat spring bars attached to the coupling-head and provided with lugs with which the coupling-plates engage; together with means for throwing the spring bars out of engagement with the coupling-plates, substantially as shown and :for the purpose set forth.

2. In a car-coupling, the combination, of the swinging coupling plates attached to vertical axes or shafts having at their upper ends rearwardly -projecting portions with lugs, spr-ings carried by the coupling -head and adapted to engage said lugs to hold the coupling-plates normally on aline with each other, flat spring bars attached to the coupling-head and provided with lugs with which the coupling-plates engage, and means for throwing the flat spring bars out of engagement with the coupling-plates, substantially as shown and for the purpose set forth.

3. In a car-coupling, the combination with the pivoted coupling-plates, of flat spring bars having outwardly curved ends and lugs with which the coupling-plates engage, and a rockshaft F having projecting arms which are adaptedto-engage with the curved ends of the flat spring bars to throw them out of engagement with the coupling-plates, substantially as described.
