UNCOUPLING DEVICE FOR CAR COUPLERS.

Application filed April 10, 1922.

T 0 all whom it may concern:

Be it known that I, Ci-ninnns W. BOOTH, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented an Improved Uncoupling Device for Car Couplers, of which the following is a specification.

This invention relates to uncoupling devices for car couplers and relates particularly to the link which connects the locking pin of the coupler with the uncoupling lever.

The object of the invention is to provide an improved link for the purpose specified, which conforms to M. C. B. and A. R. A. requirements, is simple and relatively inexpensive in construction, strong, durable and effective for its designed use.

To effect the object of the invention, my improved link comprises the various features and details of construction hereinafter described and claimed.

In the accompanying drawings, in which an uncoupling link of my invention is fully illustrated,

Figure 1 is a side view of an uncoupling device embodying a link of my invention, shown as applied in use to a standard type of vertical plane coupler, the link being shown in position corresponding to locking position of the coupler locking pin.

Figure 2 is a detached side view of the link, on an enlarged scale, showing the link members in extended relation.

Figure 3 is a view from the left hand side of Fig. 2; and

Figure 4 is a top plan view of the link as shown in Fig. 2.

In Fig. 1 of the drawing, I have, for purposes of clear and definite illustration, shown a railroad car, indicated at A, equipped with a usual type of vertical plane coupler B and an uncoupling device C embodying a link of my invention, designated as a whole D, for connecting the uncoupling lever c with the locking pin 6. Exoepting as regards the construction of the link D, said coupler B and uncoupling device C merely exemplify usual or approved forms of couplers and uncoupling devices, respectively, and both thereof will readily be understood by persons skilled in the art from an examination of the drawing without a description thereof in detail.

The link D comprises two members 0i and Serial No. 551,050.

01 flexibly connected in overlapped position by a shackle 0Z through which said link members extend and which is pivotally con nected to the overlapping ends thereof so 4 formed at the end of the uncoupling lever- 0 and in the projecting upper end of the locking pin 6.

As shown in Figs. 1 to 4, also, the shackle d engages eyes 5 and 6 formed in the overlapped ends of the link members (Z, (Z said shackle and the eyes 5 and 6 being proportioned to permit desired endwise movement of said link members relatively to each other, preferably Without spreading the overlapping ends thereof to an appreciable extent. That is, the over-all dimension of said shackle is less than the distance between the remote sides of the eyes 5 and 6 when the link members are in contact and said eyes are in transverse alignment. Also, said shackle is so proportioned with rela-' tion to the overlap of the ends of said link members that it will permit limited angular play or divergence of said link members, but will prevent each thereof from turning around the end of the other.

The proximate and lateral sides of the overlapping end portions of the link members 05, d", are flattenedsaid overlapping end portions being shown as substantially square in cross-section-and the shackle (Z is so proportioned that, when the parts of the link are assembled, said shackle will prevent said link members from turning, either on their own longitudinal axes or about each otheror, in other words,'will maintain said link members in designed operating positions To provide for conveniently attaching the eyes 1 and 2 on the link members to the eyes 3 and 4 on the uncoupling lever 0 and on the locking pin 1), said links will preferably be supplied on order with the eyes 1 and 2 open, as shown in dotted lines at 7 and 8, Figs. 2 and 3, so that, to finish the connection after said eyes 1 and 2 have been conveniently be forged from. metal bars of suitable size and cross-section or may be formed by stamping the same from solid metal plate of suitable thickness.

All connections between the parts of the link D and to the uncoupling lever 0 and locking pin 6 are made with suliicient clearance not only to provide for desired freedom of movement in operation without danger of binding, but to prevent the link from freezing up that is from becoming clogged and inoperative by an accumulation of snow, ice or sleet in its connections, which would impair or entirely prevent its operation.

I claim- 1. A link adapted for connecting the operating lever of a car coupler with the locking member thereof, comprising two link members and a member which connects said link members together in overlapped position, said connecting member being pivoted to said link members, the relation being such that said link members will be movable endwise relative to each other.

2. A link adapted for connecting the op erating lever of a car coupler with the locking member thereof, comprising two ln members and a shackle through which i link members extend and which has PlVOtlil connection therewith, the relation being SL-Jll that said link members will be movable endwise relative to each other.

3. A link as specified in claim 2, in which the link members are provided with eyes in their overlapping ends through which the shackle passes.

4. A link as specified in claim 2, in which the link members are provided with eyes in their overlapping ends through which th shackle passes and to which it is loosely fitted, the major inside dimension of the shackle being sufiiciently greater than the distance between the adjacent inner sides of the eyes in said link members when said link members are in contact with each other to provide for contemplated endwise move ment of said link members.

In testimony that I claim the foregoing as my invention, I have hereunto afifixed my signature.
