Application filed July 19 1965. Serial No. 270,321.
To all whom it may concern:
Be it known that I,JoHN F. OCoNNoR, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Draw-Bar-Centering Devices for Railway Draft-Rigging, of which the following is a specification.
My invention relates to draw-bar-centering devices for railway-cars.
The object of my invention is to provide a draw-bar-centering device of a simple, efficient, and durable construction, which will be out of the way and which will not inter fere with or require any change in the form or construction of the draw-bar, carry-iron, draft-rigging, or other parts, and which, while operating efficiently to center the draw-bar, will not in any Way interfere with the easy and quick application of the draw-bar and draft-rigging to the car and the removal of the same therefrom, and which will operate not only to center or restore to position the front end of the draw-bar, but which will also center and keep in position the middle portion and, in effect, give the draw-bar and its extension not only a sliding but a pivotal connection with the framework of the car.
My invention consists in the means I employ to practically accomplish this object or resultthat is to say, it consists, in connection with the draw-bar and draw-bar strap or extension, of a draw-bar-centering lever or device mounted above the draw bar or its strap or extension and extending longitudinally thereof and having side flanges embracing the draw-bar strap and aifording a sliding connection therewith, and which centering device or lever is pivotally connected at one end to a cross-plate extending between the center sills above the draw-bar, and thus, in effect, affording a pivotal connection between the draw-bar extension and car-frame in cooperation with a centering-spring and followers which engage the centering device or lever at the front end thereof and stops or shoulders on the cross-frame plate for the followers to abut against.
a draw-bar having a sliding connection with said centering lever or device, and through it a pivotal connection with the car-frame\vork.
My invention also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described.
In the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation, partly in central vertical longitudinal section, of a draw-bar and draft-rigging furnished with a centering device embodying my invention. Fig. 2 is a plan view. Fig. 8 is a transverse section on line 3 3 of Fig. 1, and Fig. A is a transverse section on line a I of Fig. 1.
In the drawings, A represents the center sills; A, the draft-timbers; A, the end sill; A the bulfer-block; A*, the carry iron; B, the coupler; B, the draw-bar, and B the draw-bar strap or yoke. C C are the followers, D D the side plates or stop-castings, and E E the springs of the draft-rigging. All these parts may be of any suitable or desired construction.
F is a cross-plate secured to the center sills above the draw-bar and draft-rigging and constituting the part of the framework to which the centering-lever is pivotally connected. This cross-plate is furnished with side flanges f, secured to the center sills by bolts f. The cross-plate F is provided at its rear portion with an upwardly-projecting boss f forming a cup-shaped pivot-recess f on its under side to receive the pivot-boss g of the centering device or lever G, and which is further connected at its rear end to the cross-plate F by a pin g, having head 9 and cotter The centering device or lever G is provided at its front end with a'loop or member g to receive the centering-spring H and followers K, and the cross-plate F is furnished at its front end with upright guides or flanges f which are provided with stops or shoulders f for the followers K to abut against. The guides or flanges f serve as guides for the followers and also as a case for the centering-spring H, which is embraced between the followers at the ends thereof and at the top and bottom by the upper and lower members of the loop g and at the sides by the guides f the spring being thus entirely inclosed on all sides. The centering device or lever G extends longitudinally of the drawbar and above the same and is provided with depending flanges or sides 9 which engage the draw-bar strap B on either side thereof, and thus constitute a sliding connection between the draw-bar and the centering device. The pivotal connection of the centering device G with the cross-plate 1* is at the middle portion of the draft-rigging or of the side plates D or at the point in the draft-rigging about which the draw-bar tends to turn as a pivot in its laterally-swinging movement from side to side. The draw-bar and its strap or extension while being thus entirely free to reciprocate longitudinally owing to its sliding connection with the longitudinally-extending pivotal centering-lever G is also given,through the centering device or lever G, a pivotal connection with the stationary cross-plate F, which is flxed to or forms part of the frame. In other words, my draw-bar-centering device not only keeps the middle or pivotal portion of the draw-bar-strap centrally between the side plates or stop-castings, but also operates to restore the front end of the draw-bar and coupler to its true central position by operation of the springH and its followers. Heretofore the middle portion of the draw-bar strap has not been positively centered between the side plates of the draft-rigging, but has simply been left floating, so to speak, and maintained approximately in position by the adjacent upper guide-flanges (Z of the side plates D. 7
As in my invention the draw-bar-centering device is located above the draw-bar or the extension thereof and as the connection between the draw-bar and the centering device consists simply of open or depending sides or flanges on the centering device and forming an open channel therein to receive and engage the draw-bar or its extension, the draw-bar and draftrigging may be as quickly and readily removed and replaced in the car as though it were furnished with no centering device whatever. My centering device thus does not interfere in the least with the insertion or removal of the draw-bar and draftrigging, and it operates not only to center the front end of the draw-bar, but also, in effect, to pivotall y connect the sliding draw-bar with the car-framework at the point about which the draw-bar turns asacenter in its laterallyswinging movement.
