CAR-COUPLING.

Specification of Letters Patent.

Application filed July 21, 1915. Serial No. 41,061.

To all whom it may concern:

Be it known that I, HARRY G.'] 3U 'HOU P, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and usei ful Improvements in 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 car couplers and more especially to those couplers in which the coupler head is detachably secured to the coupler stem for the purpose of permitting the ready substitution of' a new coupler head for a worn or broken one.

coupler head having a rearwardly extending disconnected when the device is in service. Generally stated, this object is accomplished by constructing thecar coupler with a coupler stem which is formed with a blfurcated forward end and by mounting thereon a hooked portion that projects into said bifurcation, the coupler stemhaving upon it a lurality of spaced devices which engage the v opposite faces of the rearwardly extending i portion of the coupler head such rearwardly extending portion being insertiblebetween the said spaced devices upon a turning movement of the head with respect to the stem, and suchrearwardly extending por- 'tion of the head having hooked'engagement with oneof the said spaced devices'to thereby prevent forward longitudinal movement of the coupler head with respect to the stem. A bolt or key passing vertically through the coupler head and stem serves as a means for preventing the head from turning with re spect to the stem so as to become disengaged from said stem.

In the drawings illustrating the preferred embodiment of my invention, Figure 1 is a plan view of a car coupler constructed in acv cordance with my invention, portionsof the head and stem being broken away; and Fig."

2 is aside elevationof the construction illus- 'trated in Fig. 1'.

As shownin the drawings, the stem '1 of the coupler is preferably bifurcated at its forward end, being forthis purpose conveniently formed with upper and lower plates or branches 2, 2 which are separated by an interposed spacing member 3 thatiis securedbetween said plates by rivets 4. At then forward ends each of the plates 2 is provided with an appropriate opening to permit the passage of a pin or bolt 5 that also passes through corresponding openings in the upper and lower walls of the coupler head 6. Between the forward end 'of the spacing member 3'and' the outer extremities of the plates 2, the coupler stem is provided 7 with a plurality of locking means which are adapted to respectively engage opposite Patented Mar. 14, 1916. a

sides of a rearward extension 7 with which i the coupler head 6 is provided. These means occupy a spaced relation to each other both longitudinally and transversely of the stem of the coupler, and preferably comprise vertlcally extending rivets 8 that" connect the plates 2 of the stem, each rivet being sur; rounded by a cylindrical thimble 9 which bears at its ends againstthe said plates and thus servesto maintain them in proper spaced relation. 7 V

1 The rearwardly extending portion 7 of the coupler head is preferably equal in height to the distancebetween the opposed faces of the plates or branches2 of the couplerstem. It also preferably extends rear-l,

wardly for a'distance sufiicient "to bring its end 'in'contact with the forward faces of the spacer member 3 when the parts are in as-i sembled relation, being thus availed of to transmit a portion of the buffing strains to the coupler stem through the sp'acer'member thereof The opposite lateral'fac'es of the rearwardly extending portion 7 of the coupler head are formed with recesses 10 and 1 11, respectively, for the'reception of the" corresponding rivets 8 and spacing sleeves 7 9, the rear end of the extension'7 being formed with a hooked portion 12 which is adapted to extend behind and have overs lapping engagement with the parts 8 and 9-which project through therecess 11; 'The 1 forward wall of the recess 10 and therear" wallof'theirecess 11 preferably extend in a transverse direction inorder to most effectively" resist any force tending to cause ,the coupler stem 1 andcoupler head to move longitudinally with respect to eachother; but therear wall of the recess 10 is inclined rearwardly, as at 13, in order to permit the coupler head 6 to be assembled upon and disconnected fromlthe coupler stem 3 by a turning movement of the head with respect to the stem. In assembling "the structure the coupler head 6 is turned with respect to the coupler stem and the rearwardly extending portion of said head is inserted between the rivets and spacing sleeves, 8 and 9, respectively, the coupler head beingthen rotated until the rear end 12 of the coupler extension 7 comes into hooked relation with the adjacent rivet .8 and the spacing sleeves 9 and rivets 8 have entered the corresponding recesses 10, or 11,

as the, case may be, of the member 7. The bolt 5 is then passed throughthe corresponding apertures in the coupler head'6 andthe apertures at the forward ends of the plates I or branches 2 of the coupler stem 1. As thus assembledthe coupler head and coupler stem are rigidly connected. To remove the coupler head it is only necessary to withdraw the pin 5 and then rotate the head 6 untilits rearwardly extending portion 7 may be withdrawn from between the members 8 and stem and having, a rearwardly extending portion, and means carried by the stem for --engaging said rearwardly extending portion of thehead to prevent said head from being detached from the stem by a, rectilinear movement, said means having en eagemert with the opposlte exterior lateral 1 faces of the said rearwardly extending portion of the head 2. In a car coupler, a coupler stem, a coupler head having a rearwardlv extending portion, and means carried by said stem and engaging the exterior lateral faces of said rearwardly extending portion or" the head for preventing longitudinal movement of said head with respect to said stem, said .rearwardly extending portion of the head being adapted to be disengaged from said means by a turnin movement of said head with respect to saic stem about an axis extending at an angle; to the longitudinal axis of said stem.

ried by said stem and head,said interfitting parts being adapted to prevent lateral ro-- tation-of said head with respect to said stem in one dlrectlon and being disengaged from each other by a lateral turning movement of 1 said head with respect to said stem in the opposite direction, said turning movement.

being executed aboutan axis extendingat an angle to the longitudinal axis of said stem.

4. vIn a car coupler, a coupler stem having a bifurcated end, a coupler head ha-vinga rearwardly extending hooked. portion that.

projects into :said bifurcation, and locking means involving a plurality of spaced: de-

vices which engage the opposite faces of said rearwardly extending portion of the coupler head, said i rearwardly extending portion ot the coupler head'being adapted to pass between said spaced devices to thereby permit the head and stem to be assembled a or disassembled by a turning movement. of

said head with respect to said stern,; and
