Specification of Letters Patent.
DRAW-BAR ATTACHMENT.
Patented May '7, Mild.
Application filed. October 8, 1914. Serial No. 865,663.
To all whom it may concern:
Be it known that I, HARRY F. WOERNLEY, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Draw-Bar Attachments, of which the following is a specification.
This invention, relates to draw-bar attachments, and more particularly to mechanism for supporting the car coupler.
Draw-bar attachments are usually provided with means for allowing vertical and lateral movement of the car coupler and while these movements of the car coupler will relieve the same of strains due to rounding. curves and variations in heights of cars, there still remains the possibility of strains in the coupler due to the twisting action set up by the swaying of the car, which is undesirable, particularly where the so called tight lock coupling is employed.
The principal object of my invention is 'to provide a draw-bar construction which will permit a limited rotative movement of the coupler.
In the accompanying drawing; Figure l is a side elevation of a draft rigging for a showing my improvement applied thereto; Fig. 2 a plan view thereof, partly sectioned on line b-b of Fig. 1; Fig. 3 a section on the line a-a of Fig. 1; and Fig. 4 a plan view of the guide support for the draw-bar.
The construction shown in the drawing comprises a radius bar 1 pivotally mounted on the pivot pin 2 and having the forward end supported by a curved guide member 3.
The car coupler head 4 is supported on a to fit a bore formed in the enlarged outer end of the radius bar 1 and the shank is secured to the radius bar by means of a flat key 8. The key 8 snugly fits the key slots of the radius bar, but the key slot in the shank 7 is made wider than the key, so as to permit a limited rotative movement of the shank relative to the radius bar.
When the shank 7 is keyed in position on the radius bar, it will be evident that strains tending to twist the coupler are relieved by the turning of the shank 7 within the bore of the radius bar, to the extent permitted by reason of the play between the key 8 and the key slot in the shank.
Having now described my invention, what I claim as new and desire to secure by Letters Patent, is:
The combination with a coupler head, of 'a draw-bar, a casting carrying the coupler head and having a cylindrical shank adapted to extend into a corresponding cylindrical socket in the draw-bar, and a fiat key adapted to extend through horizontally arranged slots in the shank and the draw-bar for securing said casting to the draw-bar, the slot in the shank being of greater width transversely than the key to permit rotative movement of the coupler head. i
In testimony whereof I have hereunto set my hand.
HARRY F. WOERNLEY. Witnesses: ALBERT G. MOORE, JOHN BATTENHOUSE.
