BUFFER. i

`Application led December 18, 1919. Serial No. 345,798.

To alli whom t may concern:

Be it known that I, ARTHUR J. BAZELEY, a citizen of the United States, residing at Cleveland, Cuyahoga County, Ohio, have invented new and useful Improvements in Buffers, of which the following is a speciication, reference being had to the accom* panying drawings, in which- Fig. l is a plan showing `a coupler l equipped with my improved buffer engaging the coupler on a carequipped with an ordi-V nary buffer; Fig. 2 is a plan similar to Fig.

l but with the ordinary buffer driven rearwardly and the coupling operation completed; Fig. 3 is a side elevation of the buffer, partly in section and the upper portion of a coupler to which it is attached;

and Figs 4l and 5 are plans similar to Figs.

l and 2, but with the coupler to which my improved buffer is attached angled in the opposite direction.

My invention relates to buffers, particu larly of the type used on engines and tenders, and comprises the providing of a coupler, and -a buffer so mounted on the coupler that it will swing radially with the coupler, and when it engages an opposing buffer will cause the coupler to which it is attached to be swung into coupling position.

My invention also consists in the construc tion and arrangement of parts which l shall hereinafter describe and claim.

Referring to the drawings, A indicates an engine coupler, B the pocket in which the coupler is mounted, and C the buffer. The coupler A is pivoted for lateral movement in the pocket B by the pin 2.

The buffer C, which is mounted upon the coupler head, has a downwardly extending flange 3, which has a rearwardly extending lip interlocking with the upwardly and forwardly extending projection 5 upon the coupler. The flange 3 of the buffer has rear wardly extending ribs 6 which bear against te the sides of the coupler horn and transmit lateral stresses from buffer to coupler.

The buffer extends rearwardly on either side of the coupler horn and is secured to the horn by the bolts 7, which seat in the ears 8 at the sides thereof, leaving the 4fr/p of the `coupler horn unobstructed so that the locklift and. lconnecting mechanism which operate through the aperture 10 may be free to function.

When the buffer C has been secured to the coupler A, as described, it will be seen that the force of bufling blows against the face of the buffer will be -transmitted to the coupler head through the flange 3 and pro Vjection 5 and that the interloclrbetween the lip 4: and projection 5 will prevent the buffer from tipping upwardly and away from the coupler. 9 bearing against the ears 8 on the coupler, which also serve to take up the buiiing shocks. s

When couplers meet on a curved track as is shown in Figs. 1 and 4t, and one of them is equipped with a buffer C, one corner of the angled face 11 of the buffer C will strike the opposing buffer D, which may be of the ordinary type, and will guide the coupler A into coupling position with the opposing coupler E as the buffer D is driven rearwardly as is shown in Figs. 2 and 5; and the face 1l of the buffer C then The ribs 6 may have extensions will lie parallel to the face of the opposing Y buffer D, in the coupling conditions shown.

When coupling on a straight track, if the coupler A is not in alignment with the coupler E the engagement of the buffer D by the buffer will swing the coupler A into coupling position.

. It has been found that when an engine. is coupled to a passenger car, there is a liability of having the passenger buffer rideup over the engine coupler and thereby injure a switchman standing on the buffer beam. There is also a likelihood of the passenger buffer injuring the lockV lifting mechanism of the engine coupler. By the use of my invention these difficulties are avoided, since my improved buffer will always enga-ge the opposing buffer and thereby serve as aprotection for the 'switchman and as a guard for the locklifting mechanism.

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

Y inluding an interlocking engagement between parts o -the coupler head and buffer.

2. In bufing mechanism for engine coup1ers, a Coupler plvoted for lateral 1novement 1n an engine pocket, a buffer, nn up- Ward projection on the coupler engaging a depending flange on the buffer, said proJoction and fiange comprising means for transmitting buing stresses from buffer to coupler.
