6 Claims.

This invention relates to coupler mechanisms and is more particularly concerned with the provision of an improved arrangement for operating the locks of standard A. R. A. type D couplers. In the patent to Kinne, No. 1,639,300, dated August 16, 1927, there is disclosed an operating means for such locks; which operating means comprises an element rotatably mounted in a pair of transversely spaced supporting lugs integral with therefrom, said rotatable element being releasably engaged by a lifter arm which in turn is connected by a link with the coupler look. In the annealing of couplers provided with the lugs aforesaid said lugs tend either to separate or to approach each other, with the result that the assembly of the parts is thereby rendered difficult. I have provided an improved construction which effectively overcomes this difficulty. Through my arrangement asimplified and efiicient, lock operating means is provided and shifting of the supporting lugs is prevented .so that facility of assembly is insured. Other features of the invention will be hereinafter described and claimed.

In the accompanying drawings:

Fig. 1 is a fragmentary vertical sectional view of a standard A. R. A. type D coupler embodying my invention, the coupler lock being shown in locking position.

Fig. 2 is a bottom plan view of the coupler of Fig. 1.

Fig. 3 is an end view of my improved lock lifting or operating mechanism in position on the coupler supporting lugs.

Fig. 4 is a fragmentary view of the coupler of Fig. 1 showing the lock lifting member in uppermost position.

Fig. 5 is a front elevation of the improved lock lifting or operating member.

Fig. 6 is a side view of said member, and v Fig. 7 is a fragmentary vertical sectional view with parts omitted showing in dotted lines the position of the lock lifter during the assembling thereof to the coupler unit.

Referring to the drawings there is shown a standard A. R. A. type D coupler having a head 5 to which a knuckle B is pivoted by a pin 6'. Cooperating with the knuckle 6 in the usual way is the customary lock 1 having a dependent leg 8 in the lower end of wnich the usual diagonal slot 9 is provided. The lock 1, in locking position (as shown in Fig. 1) rests with its rear shoulder l0 upon the knuckle opener H. The parts above mentioned, being all old in the standard tion l4.

the coupler .head and depending coupler referred to, need not be further described.

For lifting or operating the look I, I have provided a lifter element designated generally by the numeral l2. This element has extending therefrom an arm l3 provided with an eye por- A link l5 (which may be the same as the link 50 in the Kinne patent above referred to) has a pin l6 engageable with said eye portion 14, and also carries a pin II receivable within the above-mentioned slot 9, whereby the lifter element is connected to said lock. Also extending from the body of the lifter element I2 is a hook l8. Integral with and dependent from the coupler head 5 is a pair of transversely spaced lugs l9, l9, which lugs have integral therewith and extending therebetween a bearing element 20. The hook I8 on the lock lifting member I2 is adapted to be engaged with said bearing element 20, said hook being movable into engagement. with said element during assembly of the parts as indicated in Fig. '7. Thru the lifter element l2 and the link 15 it will be evident that the lock may be readily shifted from its locking position shown in Fig. 1 either to its lock set position or to its uppermost position (Fig. 4)

The lock lifting or operating member I! may, as shown, be provided at each side thereof with eye members 2|, 2| each of which is adapted to receive the hook end 22 of an operating rod 23 which may be of standard construction. Said eye members, as shown, include portions 2|, 2| which extend laterally from the lock operating member 12 at points intermediate the length thereof and between the portions l4 and I8 thereof. The provision of the eye portions 2|, 2| enables said lifter element l2 to be operated by either of the two

rods

23, 23, or, in other words, to be operated from either side of the coupler. It will be further seen that in the arrangement above described, the bearing element 20 integral with the lugs l9, l9, prevents warping orrelative I shifting of said lugs with respect to each other, and thereby insures that the lock lifter element I! may be readily assembled between said lugs to complete the unit.

If desired, the lock lifter element l2 may be operable from but one side of the coupler and may for this purpose be provided with but one eye portion 2|.

It will be seen from Figs. 1-4 and 7 that the lugs 19 form downward and rearward extensions of the side walls 23 of the opening 24 into which the lock leg 8 projects. A horizontal wall 25 joins the upper portions of the lugs l9, 1. e., the portions thereof directly rearward of the side walls 23. This horizontal bridging wall 25, as will be apparent from Figs. 1 and 4, cooperates with the hook i8 and bearing element 20 to prevent displacement of the lock operating element I? out of engagement with said bearing element in all operative positions of said element.

The terms and expressions which I have employed are used as terms of description and not of limitation, and I have no intention, in the use of such terms and expressions, of excluding any mechanical equivalents of the features shown and described or portions thereof, but recognize that various structural modifications are possible within the scope of the invention claimed.

I claim:

1. In combination, an element for operating a lock of a car coupler, said element comprising in a unitary structure a lever arm having a hook shaped portion at one end adapted to engage an integral trunnion on a car coupler for pivotally mounting said element, and provided with integral means extending forwardly from said por-- tion for connection to said lock, a member for connecting said element to said lock, means pivotally connecting said member to the forward end of said forwardly extending means, means joined to said lever arm intermediate said hook-shaped portion and said forward end of said forwardly extending means for attachment of an operating mechanism, and a rotatable operating rod having an end adapted to engage said means and cooperating therewith to transmit torsional forces from said rod to said means, said means comprising an eye for receivingsaid rod and centered on the axis of rotation of said element.

2. In a car coupler comprising a head, a knuckle and a lock for said knuckle, said lock having a leg extending into an opening in the bottom of the coupler head, a pair of projections to the rear of said lock and extending downwardly with respect to the side walls of said opening and integral therewith, each of said projections extending in the vertical plane of a respective one of said side walls, a bearing element extending between said projections and integral therewith, a lock operating member having a hook shaped portion engageable with said bearing element, means connecting said member with said lock, said member having means thereon providing a support for a rotatable operating element and a substantially horizontal wall bridging said projections and positioned above said hook shaped portion of said lock operating member for preventing displacement of said member out of engagement from said bearing element in all operative positions of said member.
