ISAACH. MILLIKEN, OF ASPINWALL, PENNSYLVANIA, ASSIGNOR TO THE MoCONWAY & TORLEY COMPANY, OF PITTSBURGH, PENNSYLVANIA, Av CORPORATION OF PENNSYLVANIA.

To all whom it may concern lie it known that I, Isaac H. MILLIKEN, a citizen of the [United States, residing at Aspinwall, in the county ofAllegheny and State of Pennsylvania, have invented certain new and useful Improvements in \Vear- Platesfor Car-Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the construction of wear plates for interposition between a car coupler and its supporting carry-iron to prer vcnt'the coupler from being wornaway by the constant rubbing against the carryiron to which it is subjected in service. The principal object of the invention is to produce a device of the character indicated which readily lends itself to .renewalwhen worn orfif broken, and which may be detachably connected to the car coupler by interrelated structural parts without weakening the coupler 'or interfering with other parts of the car equipn ent with which the coupler is associated. This object, generally stated, is attained by combining with the car coupler a wear, plate provided with means detachably engaging the coupler to prevent lateral movement of the plate with respect thereto, and having also means detachably engaging the coupler to restrain.

longitudinal movement of the plate relatively to the coupler.

In the drawings illustrating my invention, the scope whereof is pointed out in the claims,

Figure 1 is an inverted plan view of a construction embodying the invention.

Fig. 2 is a view, partly in side elevation and partly in section, illustrating the construction shown in Fig l, a supporting carry-iron being shown in section.

4 may be made of either forged or cast material; that illustrated in Figs. 5 and 6 is be sprung into andout of interlocking relation with the coupler.

p In the drawings, 1 indicates the head of a car coupler and 2 is its stem. Except as hereinafter claimed these parts may be of any desired construction.

I In the-form of the invention illustrated in Figs. 1 and 2 the coupler is provided'on its under side substantially at the junction of the coupler head 1 and stem 2 with a downwardly extending lug or projection 3 affording a rearwardly facing transverselvextending shoulder adapted to engage the corresponding transversely extending forward end 4: of a wear plate 5. At its rear end the wear plate is provided with a projection G'which enters a recess or aperture 7 in the under side of the coupler. The projection 6 is preferably of hooked form, as shown, overlappingly engaging the coupler so as to support the rear end of the plate 5. The opening T in the coupler stem is sufficiently elongated to allow the hooked projection 6 to enter; but the lateral walls of the opening preferably closely embrace the sides of the projection 6 so as to restrain lateral movement of the rearend of the Wear plate with respect to the coupler. When the parts are in assembled relation, lateral shifting of the forward end of the plate 5 with respect to the coupler is prevented by the'engagement of its transversely extending end 4 with the rear face of the projection or lug 3 on the coupler. 1 Forward movement of the plate 5 upon the coupler stem is prevented by the engagement of the forward end of the plate with the lug 3, while the engagement of the hooked projection 6 with the rear wall of the orifice 7 in the coupler stemprevents rearward movement of the plate with respect to the coupler. In service the wear plate 6 is disposed between the under side of the couto the stem 2 of the coupler by means of a hooked projection 6 that enters a recess 7 in the coupler, as already described. As will,

and dis designed to be resilient so that, as

shown in dotted lines at 11, it may be sprung into and out'of assembled position. Like the other forms of construction it is preferably provided at its rear end with a hooked projection 6 entering an orifice in the under side of the coupler stem. Its forward end is preferably provided witha tongue or projection 112 extending into a correspondingrearwardly opening recess 13 formed in transversely extending lug 14 that projects downwardly from the under surface of the coupler substantially at the junction of the coupler head 1 with the coupler stem 2. Thecarry-iron 8 on which the plate 11 rests is shown in Fig. 6. i

7 It is preferred that the abutting and con tacting shoulders or faces of the wear plate and coupler shall it closely against each other, because the highest degree of efiieiency in protecting the coupler from wear is attained when all movement o flthe wear plate with respect to the coupler is .eliminated. i Iclaim: i

. ,1. In a device of the character indicated, the combination with a car coupler, of a wear plate arranged on the under side thereof, and a carry-iron for supporting said wear plate and coupler, said coupler and wear plate having transversely extending engaging shoulders atone end of said wear plate and longitudinally extending en- "gaging shoulders at the opposite end of said shouldered engagement with said couplersubstantially at the junction of said head and stem the rear end of said wear plate having interlocking engagement with the coupler to thereby support said end of said plate against vertical movement.

3. Ina device of the character indicated, the combination with a car coupler, of a carry-iron and a wear plate provided with means detachably engaging the coupler for preventing lateral movement of the wear plate with respect to said coupler and provided with. means detachably engaging the coupler for preventing longitudinal movement ofthe wear plate with respect to the coupler.

4. In a device of the character indicated, thecombination with a car coupler, of a resilient wear .plate detachably mounted thereon, said wear plate and coupler having interlocking portions ada-pted to be disen gaged by flexing said plate. I

In testimony whereof I'aflix my signature.
