CAR-COUPLING.

sPEoIFroAfrroN forming part of Letters Patent No. 502,260. dated-July 25, 1893.

l Application filed February 24, l 893. Serial No. 463,657. (No model.)

To all whom t may concern.-

Be it known that I, HENRY O. MILLER, a citizen of the United States of America, residing at Eaton, in the county of Weld and State of Colorado, have invented certain new and useful Improvements in Car-Couplings; and I do 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, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification. v-

My invention relates to improvements in car couplings and the construction consists of the features, arrangements and combinations hereinafter described and claimed, all

of which will be fully understood by reference to the accompanying drawings in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a horizontal section taken through a drawhead provided with myimproved coupling mechanism. .This section is taken on the line {zj-Jy, Fig. 2. Fig. 2 is a vertical section taken on the line Fig. l. Fig. 3 is a similar section taken through the drawhead, a modified form of couplinghook being shown in elevation. Fig. 4 isa transverse vvertical section taken on line z-z, Fig. 3. Fig. 5 is a perspective view of the linksupporter. Fig. 6 is a similar viewl of the spring used in connection therewith. Fig. 7 is a top or plan view of the drawhead on a reduced scale.

Similar reference characters indicating corresponding parts or elements of the mechanism in the several views let the numeral 5 designate the drawhead, recessed to receive the coupling hook 6 and the locking bar. This hook is pivoted in the drawhead and is substantially of the saine construction as that shown in my Patent, No. 490,811, granted January 31, 1893, application Serial No. 428,588, filed April 11, 1892, as is also the locking bar 7, which engages the upper extremity of the hook when in the locking position. The coupling hook is pivoted on a horizontal pin 8 held in place by keys 9 passing through its extremities which project outside of the drawhead sufliciently for the purpose. The pivot Pin 10 of bar 7 is also provided withv retainjecting extremities.

ing keys 12 passed through its exteriorly pro- Bar 7 is provided with an eye or ring 7a formed on its upper surface,

of any suitable uncoupling or unlocking mechanism. This mechanism is not shown or described in this application as nothing is claimed thereon. A

, Vhen the cars are coupled or'when the lilik is' in the drawhead imposition for coupling, the link extremity is located ina recess 14 formed in the coupling hook and is retained 'in the drawhead by the hook or projection 6 located in front of the recess. The v'link 15 is supported in the horizontal position ready for coupling with the hook of the opposite drawhead, by the supporting plate 16 located in the lower part of the drawhead near the entrance of thev link recess 17 into which it projects upwardly when the coupling device is in the locking position, and supports the links by engaging the same from beneath. This supporting plate is pivoted on a pin 18 passed through apertures formed in the sides of the drawhead and held in place by keysl 19 passed through apertures formed in its extremities. The lower part of plate 16 is centrally cut away as shown at 2O while the parts16c on each side of the recess are bent downwardly over the pivot pin whereby the plate is movably supported thereon. This plate is further provided With lugs 16a projecting from either side of its upper extremity and entering ways 20 formed in the drawhead on each side of the link recess.

A spring 21 is attached to pin 18 between parts 16c of the supporting plates. One part 21a of this spring engages the inner surface of plate 16, while the other part 2lc projects backward into the path of a lug or short pin 22 formed upon or attached to the coupling device whereby as said device is moved to the locking position or that shown in`Figs. 2 and 3 the pin 22 engages part 21e of the spring and raises the plate 16 to engagement with the link. This spring is so constructed that while it maintains the supporting plate in operative relation with the link, it reacts on the pin 22 and maintains the coupling device in engagement with the locking bar 7.

In the modified form of couplingdeviceillustrated in Figs. 3 and 4, the hook 6* is cut the same affording meansfor the connection ICO away and a forked pin 6d slipped over the forward extremity of the device and having a vertical movement in ways 23 formed in the adjacent walls of the drawhead. The body part 6 of the coupling device is provided with pins Gg which enter slots 6h formed in arms Gl of the forked pin 61. Hence as the coupling device is moved to the unlocking position it carries the pin 6d downwardly a sufficient distance to release the link as shown by dotted lines in Fig. 3. p

Having thus described my invention, what I claim is 1. In a car coupling the combination with the drawhead and link, of the coupling device pivoted in the drawhead, the link sup-- porting plate pivoted in the lower part of theA drawhead near the entrance of the link re-y cess into which it is adapted to project, and

the double spring movably supported on theV pivot, one part engaging the supporting plate on the under side and the otherpart project` ing backward into the path of a projection; formed upon the locking device whereby as said device is raised to the coupled position;` said projection engages the spring and raises the plate to engagement with the link, sub stantially as described.

2. In a car coupling the combination withv the drawhead and link, of the pivoted coup` ling device, the movable link supporting plate and means actuated from the coupling device: whereby the supporting plate is maintainedl inoperative relation with the link, substantially as described.

3. The combination with the drawhead, link and pivoted coupling device, of a link supporting plate pivoted in the drawhead at one extremity and carrying projections at the opposite extremity adapted to enter guide ways formed in the adjacent wallsV of the drawhead, and means actuated from the coupling device whereby the said plate is maintained in operative relation with the link, substantially as described.

4:. The combination with the drawhead and link of the coupling device projecting into an opening formed in the upper part of the drawhead, the pivoted locking bar engaging the same, the link supporting plate and means actuated from'the coupling device whereby said plate is maintained in operative relation with the link, said means being adapted to react on the coupling device and hold the same in engagement with the locking bar, substantially as described.

5. The combination with the drawhead of thecoupling device pivoted therein and carrying a locking pin adapted to movein Ways formed in the `adjacent walls of the drawhead as theV coupling device moves from oneposition to the other, substantially as described.

6. The combination `with the drawhead ot'- the coupling device pivoted therein and carrying the vertically movable lockingpin en-` gaging ways formedin the walls of the draw- `1 head and slotted to receive a projection formed upon the coupling device whereby as said device moves the locking pin passes from the one position to the other, substantially as described.
