HENRY F. POPE, 0F CLEVELAND, OHIO, ASSIGNOR TO THE NATIONAL MALLEABLE CASTINGS COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.

DRAFT-GEAR AND BUFFING MECHANISM.

To all whom it may concern Be it known that I, HENRY F. Porn, a citizen of the United States, and a resident of Cleveland, Ouyahoga county, Ohio, have invented a new and useful Draft-Gear and Bufling Mechanism, of which the following is a specification, reference being had to the accompanying drawings, in which Figure 1 is a plan view partly in section showing my radial draft-gear; Fig. 2 is a vertical longitudinal section, partly in side elevation; Fig. 3 is an enlarged detail view partly in section, showing the manner of connecting the buffer and coupler shanks; Fig. 4 is a sectional perspective View of the coupler shank extension; Fig. 5 is adetail plan view showing a modified construction; and Fig. 6 is a side elevation of the same.

The purpose of my invention is to provide a draft gear having a radially swinging coupler and a radially swinging buffer related so as to operate together and. to afford efficient means by which both the coupler and buffer can adapt themselves to the motion .of the car truck as it passes around curves, and will operate properly under all such conditions of use. The device is especially adapted for passenger cars- .This socket has opposite lateral recesses in which connecting plates 5 are fixed, preferably by bolts 6 which pass through the plates and through the socket and the contained coupler shank. The plates extend upwardly and serve to give a connection between the coupler shank and the buffer mechanism, as explained below.

The extension 3 at its rear end is curved upwardly and is connected by a yoke or other suitable device 7 with a draft rigging 8 set between the sills of the cars, and the coupler shank is also preferably provided with a sliding sleeve 9, from which guiding connections 9 are extended to the truck in a manner as heretofore known. These guiding connections are preferably made in the form of telescopically fitted Specification of Letters Patent.

parts containing springs 59, and they are pivo-tally connected at 9 and 9 to the socket 9 and to the truck-frame of the car, respectively. The construction of the draft rigging is notof the essence of this invention. The coupler shank is supported by carry-irons 10 which extend between the sills of the car and may be supported by hangers 11. The coupler shank extension 3 has a vertical pivot pin 12 which connects it to the yoke 7 so that when the car is passing around curves the coupler and its shank will swing radially on the axis of the pin 12 and will constantly be kept thereby approximately at the central portion of the railway track.

13 is the face plate of the buffer, having a rearwardly-extending forked shank formed with two parallel arms 14, 14:, as shown in Figs. 2 and 3. Between these arms of the buifer extends a transverse carry-iron 15 which is curved as shown in Fig. 1, and is connected to the center sills 16 and intermediate sills 16 of the car.

The rear end of the forked buffer shank is held by a spring casing 19, preferably made in two longitudinally divided parts, and the said shank has at the outer surfaces of its arms 14, 1 1 sockets shown by dotted lines in Fig.' 3, to which projections c, 0 011 the casing extend so that when the parts of the casing are held by the bolts they will be clamped firmly and rigidly upon the arms of the buffer shank, a filler piece 19 being interposed between the arms. The spring casing extends rearwardly from the buffer shank, and fits telescopically over a rear spring casing 21 which extends within the spring casing 19 and contains interposed butfing spring mechanism which is compressed by backward motion of the buffer shank and the spring casing 19. The spring mechanism comprises preferably two

springs

22 and 22, the spring 22* being an auxiliary spring of less capacity than the main spring 22, and being designed to exert a constant tension sufficient to force the buffer and its shank outwardly and to keep it in contact with the corresponding buifer of another car, even when the coupler shank is under draft and is drawn out to its full extent. This spring also aids the main spring 22 in the work of bufiing under compression.

The construction and arrangement of the buffer spring mechanism may be varied in many ways,-since my invention does not relate thereto, but relates to the manner in which the buffer with its spring mechanism is connected to the extension of the swinging coupler shank and is thus backed by the draft rigging 8. For this purpose, as shown in the drawings, the extension 3 of the coupler shank is provided with an upwardly projecting shoulder or portion 23, preferably formed integral with the extension 3 and constituting a shoulder against which the rear end of the buffer mechanism, preferably an extension of the spring casing 21, has an end bearing. The rear end or extension of the spring casing 21 and the face of the shoulder 23 are preferably flanged, as shown in detail in Figs. 3 and 4:, being provided with interfitting flanges a, b, so that the buffer mechanism will not be displaced laterally from engagement with the extension of the coupler shank. Instead of this device I may use the device shown in detail in Figs. 5 and 6, in which the

parts

21 and 23 are provided with abutting flanges a, b, which are bolted together with bolts (5. The particular part of the buffer shank which bears on the shoulder 23, and the location of the spring mechanism in the buffer shank are not essential to my invention broadly considered. This arrangement, however, may be varied.

In the form of Figs. 5 and 6 the member 21 forms a structural part of the coupler shank extension, being rigidly secured thereto.

The engagement of the buffer with the coupler shank is effected by the plates or projections 5, which, extending upwardly from the coupler shank as above described, fit on opposite sides of the spring casing 19, as shown in Fig. 3 so as to permit independent longitudinal motion of the coupler shank and buffer. The coupler head and buffer also engage at 24. The transverse member of the buffer is thus kept at right angles to its shank and also to the shank of the coupler.

WVith the construction above described the coupler and its extension will swing radially on the axis of the pivot 12 as the car passes around curves, and the buffer mechanism will also swing therewith, being guided and moved by the connection 5 with the coupler shank. The stresses of butting are transmitted through the coupler and the coupler extension 3 to the draft rigging, and through the buffer plate 13 and its arms and spring mechanism through the coupler extension 3 and thence to the draft rigging.

I claim 1. A laterally swinging draft member mounted for longitudinal movement in buffing and draft, a draft-rigging, a laterallyswinging buffer swinging with the draft member and having a centrally located shank which has a relatively stationary rear bearing against the draft member, whereby stresses of butling are transmitted through the draft-member to the draft-rigging.
