3 one of the brackets therefor.

To all whom it may concern:

Be it known that I, THOMAS J. FUTRELL, a citizen of the United States, esiding at Streator, in the county of La Salle and State 5 of Illinois, have invented new and useful Improvements in Automatic Couplings for Railway Cars, of which the following is a specification.

One object of my resent invention is the provision of eflicient and durable suspension and cushioning means for use in automatic couplings with a View to promoting the reliable operation thereof.

Another object is the provision of suspension and cushioning means calculated to readily lend itself to the retraction of a coupling and the retention of the coupling in retracted position, when occasion dei'nands.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, hereby made a part hereof z- 1 Figure 1 is a view in side elevation showiii-g a coupling embodying my invention, and also showing a portion of a complementary coupling associated with the first-named coupling. v

Figure 2 is a transverse section taken in a plane parallel to the swinging hanger of my improvement.

Figure 3 is a detail vertical section show ing' tne association of the said hanger with section taken at right showing the arrangehanger bracket.

Figure 4 is a detail angles to Figure 3 and ment of one arm of the swinging relatively to the side portions of its Similar numerals of reference designate corresponding parts in all of the views of the drawings. I

in furtherance of'my present invention I 1'1; on the frame 1 of a car body two pendent spaced brackets 2. The said brackets 2 are identical in construction and therefore a detailed description of the one shown in F igures 1, 3 and 1 will suflice to impart a definite understanding of both. lhe bracket referred to includes side walls 3 in which are openings 4, and a front wall 5 integral with the side walls 3 and provided with a bore 6. Thesaid front wall 5 is also pr vided as shown with a web 7 on which are flanges 8 to contribute to the strength of the fixture of the bracket 2 to the frame 1.

Pivotally connected at 9 in the upper portions of the bracket 2 are arms 10 of the swinging hanger 11 which constitutes an important element of my improvement. As appears in Figure 2 the said swinging hanger 11 is of general U-configuration, and its arms 10 are connectedthrough the medium of an intermediate cross bar 12. Carried by the said cross bar 12 and also by the lower cross bar 13 of the hanger 11 are alined bearings 14.

Positioned in the swinging hanger 11 and movable therewith is a yoke 15 on which are upper and lower trunnions 16, journaled in the said bearings 14.

Mounted to rock in the yoke 15 and in a longitudinal vertical 18, the sleeve 18 being preferably larger than the Pivotally connected at 19 to each arm 10 of the swinging hanger 11 is a rod 20 that extends outwardly through the bore 6 in the adjacent bracket 2 and is provided at 21 with an abutment adapted to bring up against the inner side of the front wall 5 of the bracket as clearly shown in Figure 3. On the outer portion of each of the two rods 20 is an abutment 22, and surrounding each rod 20 and interposed between its abutment 22 and the outer side of the adjacent bracket 2 is a cushioning spring'28. The relative arrangement of the two springs 23 is clearly shown in Figure 2.

It will be apparent from comparison of Figures 1 and 3 that the outward or forward swinging movement of the hanger 11 is limited by the front walls 5 of the brackets 2, and that the hanger is free to swing inwardly beyond the side walls of the brackets 2 after the manner indicated by dotted lines in Figure 1. In order to retain the hanger 11 in its inner idle posihe position shown by dotted lines in Figure 1, I provide the hook 24c pivotally connected at 25 to the frame 1 and adapted to be engaged with and disengaged from an apertured portion 26 in one of the swinging hanger arms. I would have it understood here that precedent to the said connection of the hanger 11 to the hook 2a the pintles 19 are removed so as to release the hanger arms from the rods 20.

At 27 in Figure 1, I illustrate what it is proper to designate, a cushioning hanger. The said hanger comprises a cylinder 28 loosely connected at 29 with. the car frame and having an apertured lower cap 30 that constitutesan abutment, a piston 31 movable in the cylinder 28, a rod 32 on the piston, freely movable in the cap or abutment 30, and a spring 33 housed in the cylinder 28 and interposed between the abutment 30 and the piston 31 so as to yieldingly resist downward movement of the latter. At its lower end the piston rod 32 is connected as indicated by 34 to a coupling head 35; and it will be noticed by reference to Figure 1 that I show in proper relation to the coupling head 35 a complementary coupling head 36i. e., a coupling head that is carried by an adjoining car (not shown). As shown in Figure 1 the coupling head 35 is provided with a rectilinearly movable latch bar 37, and pivotally connected to the outer portion of the said latch bar 37 is one arm of a lever 38, fulcrumed at 39 on the coupling head35. The said lever 38 has its other and inner arm connected to a link 40, and the said link 40 is pivotally connected at 41 to a rod 42 as is also a link 43 that is pivotally connected at 4:4: to the coupling head 35. The rod 42 is provided at &5 with an abutment. The said rod 432 is also carried loosely through the sleeve 17 in the yoke 15. Mounted on the rod 4:2 and interposed between the said abutment 425 and the outer end of the sleeve 17 is a spring 46 which has for its function to yieldingly retain the latch bar 37 in and return the same to its working position.

The links 40 and 43 constitute a toggle lever, and hence it will be understood that when the rod 42 is moved toward the right in Figure 1 by the engagement of the sleeve 17 with the units L2, be latch bar 37 will be retracted for the uncoupling of the coupling heads. Manifestly when the hanger 11 is secured by the hook 24: in the position shown by dotted lines in Figure 1, the latch bar 37 will be retained in retracted position.

Joined to and movable with the coupling head 35 is a rod 47 that is arranged to work freely through the sleeve 18 in the yoke 15; and it will be readily noted by reference to Figure 1 that a coil spring 48 on the said rod 47 is interposed between the outer end of the sleeve 18 and an abutment 4:9 afforded by the inner portion of the coupling head 35.

It will be apparent from Figure 1 that 35 is equipped with the following conventional appurtenances, viz; a steam pipe 50, a train cable tube 51, and a signal tube 52. These, however, are not of the essence of my invention and need not therefore be further mentioned.

It will be apparent from the foregoing that through the medium of my improvement which I have illustrated and described as the best practical embodiment of which I am cognizant, the coupling is suspended and cushioned in a manner that is entirely adequate for practical purposes, and also in such manner that all of the parts are well adapted to withstand the rough usage to which car appurtenances are ordinarily subjected. In this connection it will be appreciated that all of the parts of my improvement are adapted to freely lend themselves to the movements of the car body so as not to be subjected to strain.

It will also be apparent that my novel mode of suspending and cushioning the coupling head is of such character as to readily lend itself to the retention of the coupling head and its appurtenances in a retracted position as when it is couple train pipes by hand or perform any other function with which the coupling head in its normal working position would interfere.

An important characteristic of my invention resides in the fact that under normal working conditions, the hanger 11 will bear solidly against the outer walls 5 of the brackets 2 and in that way will sustain practically all of the pulling strain to which the coupling is subjected.
