14 Claims. 1

This invention relates to improvements in railway cars and more particularly to improvements in means for supporting the outer end of a railway car coupler adjacent its head.

My present invention is an improvement over Patent No. 1,923,433 granted to me on August 22, 1933, and Patent No. 2,308,032 granted tov James S. Swann on January 12, 1932, both of which patents are assigned to the same assignee to which this invention and application will be assigned.

One or" the objects of the invention is to support a railway car coupler upon a device which permits the coupler to move horizontally and vertically with the coupler of another car when coupled thereto as the couplers adjust themselves to the curves and unevenness of the track, as well as causes the coupler to return to normal coupling range when free to do so; for instance, when a coupler supported by my device is uncoupled while the railway car is upon a curved track.

Another object of the invention is to provide a resilient means in a carrier for supporting the outer end of a coupler at a desired elevation during service movements of the car, but which means permits downward and/or lateral movement of the coupler when an additional live load is applied such as when two coupled cars are pulled over a track elevation, hump, vertical curve in the track, or around a curve, and wherein said carrier, when free to do so, will return the coupler to its normal height and simultaneously to a position at least adjacent the center of the car within coupling range.

Another object of the invention is to reduce the service stresses in the coupler by providing a resilient coupler carrier thereby permitting the outer end 0! the coupler to move vertically so that the center line of coupled couplers will be nearer a straight line, thus reducing the resultant force in the coupler shank. When the force ceases, as when the cars are uncoupled, the resilient carrier returns the coupler to its normal vertical position, which is an essential in accepted railroad operation when coupling railway cars.

A further object o! my improved resilient coupler support and coupler centering device is to prevent jar in the coupler, caused by uneven track and the movement of the coupler on the carrier, from being transmitted by the coupler to adjacent car parts, and furthermore, to reduce the friction and wear between the associated parts.

Another object is to provide a resilient means which cushions'and centers the coupler by maintaining the carrier in adjustment with the coupler, and which may be readily and quickly assembled or taken apart; is very light in weight and economical to manufacture.

Another object of the invention is to resiliently support the coupler by a pair of spaced apart springs and provide means whereby upon lateral movement of the coupler (in either direction) a predetermined distance the springs will not be distorted, but upon lateral movement of the coupler beyond said predetermined distance the springs will be distorted, thereby causing a tend= ency to return the coupler to its normal coupling range. The object of such arrangement is to relieve the springs of any distortion during normal service movements of the car, but to provide means to return the coupler to its normal central position upon an abnormal lateral movement of the coupler, or upon movement of the coupler beyond its coupling range. The distance two couplers are out of alignment and will still couple is called the coupling range.

Throughout the specification, wherever the term coupler is used, it is understood to mean a standard railway car coupler whereinno provision is made for the coupler to rotate around its longitudinal axis.

Also in the modifications of the invention some of the elements roll, some rock and some do both simultaneously, therefore, applicant has used in the specification and-claims the word roc (and derivations thereof) with the understanding that, for the purpose of describing the invention, the term includes rocking and/or rolling action.

In the drawings:

Fig. 1 shows the striking casting of a railway car with my device applied thereto Fig. 2 is a section on line 22 of Fig. 1.

Fig. 3 shows the coupler and my device in normalposition; that is, adjacent the middle of the car.

Fig. 4 shows the coupler and the relative p'osition'of the component elements of my device when the coupler has been moved laterally a predetermined distance.

Fig. 5 is the same as Fig. 4 except that the coupler has been moved laterally more than said predetermined distance.

Fig. 6 shows a modification of the invention with the coupler in normal position.

Fig. 7 shows the modification with the coupler moved laterally a predetermined distance.

Fig. 8 shows the modification with the coupler moved laterally more than said predetermined distance.

The construction shown' in Figs. 1 and 2 is diagrammatically illustrated in Figs. 3, 4 and wherein the coupler 2 is normally positioned at the middle 3 of the'car and is arranged to move laterally and/or vertically of the car in service. The coupler rests upon a coupler carrier 4 which moves vertically with the coupler and the carrier 4 is provided with lugs 5 on opposite sides of the coupler so that the carrier moves laterally in horizontal planes, in either direction, with the coupler. A member 6 having a portion I below, the coupler is fixed to thestriking casting 8 by the bolts 9.

My improved device is positioned between the fixed member 6 and the coupler carrier 4 and supports the coupler 2 and carrier 4 upon the fixed member 8.

Fig. 3 shows the relative position of the coupler 2, carrier 4 and the several parts of my device when the coupler is in normal position; that is, adjacent the middle 3 of the car..

My device comprises a spring seat It) pivotally mounted I 1 upon the fixed member 5 to swing laterally of the car and a spring cap l2 pivotally mounted l3 upon the carrier 4 to swing laterally of the car and springs I 5 interposed between the' spring cap l2 and spring seat It] and spaced equi-distant on opposite sides of the pivots H-l3. These pivots are preferably positioned adjacent the middle 3 of thecar. In this position the springs resiliently support the coupler 2 and the carrier 4 and cushion the coupler against the service movements due to rough and uneven track.

Fig. 4 shows the position of the coupler 2, carrier 4 and associated parts of my device when the coupler has moved laterally toward one side of the car, in which position it may not be necessary to return'the coupler to the middle of the car, because the coupler in this position is within coupling range; that is, close enough to couple with the coupler of an oncoming car. In practice this will be about /8" lateral movement of the coupler. To assume this position the spring cap l2, springs I5 and spring seat I!) have swung as a unit about both pivots I ll 3 without distortin the springs and without affecting their efliciency as to cushioning means for the coupler.

Fig. 5 shows the coupler 2, carrier 4 and associated parts of the device when the coupler has moved beyond' the above mentioned predetermined movement of about to about 1%" which is the permissible movement in freight cars.

When the coupler has been moved laterally tothe position shown in Fig. 4 the spring seat ID has engaged a stop I6 on the member 6 fixed to the car so that further movement of the spring seat is arrested. However, further lateral movement of the coupler will carry the carrierandspring cap with it and cause the springs to be distorted, as shown in Fig. 5, which distortion provides a stored force which causes the springs to urge the carrier and the coupler toward central position; that is, at least to a position within coupling range. The coupler and carrier will thus be returned to coupling range when the coupler is free to so return which will be when the coupler is detached from the other coupler. Any desired means, such as the lugs l4. on'the spring seat and spring cap may be used to hold the springs in place.

The word distorted, as used herein, means compress the springs too muchand any construc-] tion may be used to restrict the movement of the coupler carrier lengthwise of the car though permitting said carrier to freely move laterally of the car. It is common practice to allow a carrier to swing laterally of the car between two walls which are fixed to the car, and arrange such walls to limit the downward movement of the carrier.

Figs. 6, 7 and 8 show a modified construction wherein the carrier 30 performs the functions of the spring cap so that a separate spring cap is not necessary and the spring seat is in the form of a rocker 3| which rocks upon the fixed member 5 when the coupler moves laterally. In the modification the carrier 30 is held in a horizontal position by the coupler as the coupler is moved laterally, When the coupler moves laterally a predetermined distance to the right (as shown in Fig. 7) the rocker 3i rocks upon the fixed member 6 and the left spring 32 is compressed while the right spring 33 isneither compressed nor has moved a predetermined amount (as shown 'in Fig. 7) neither of the springs 32-33is distorted, but upon further lateral movement of the coupler, the' springs pivotally swing upon the

pivots

35 and 38 and engage the inclined surfaces in the carrier and spring seat, respectively, at the opposite diagonal corners thereof, which distorts both of thesprings, as shown in Fig. 8, thus.

providing an additional force to urge the device and coupler toward normal position. As the device moves from the position shown in Fig. 7 to that shown in Fig. 8, neither of the springs is further appreciably distorted. Any desirable meansmay be used to prevent the rocker 3| from slipping upon the fixed member 6.

The accompanying drawings illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof, within the scope of the claims, will occur to persons skilled in the art.
