Williams, Battle Creek, Mich., assignors to Clark Equipment Company, Buchanan, Mich., a corporation of Michigan Application September 28, 1934, Serial No. 745,845 12 Claims. (Cl. 213-75) The present invention relates generally to car hand coupling members shown, respectively, in coupling devices and has for its principal purpose a provision of new and improved car coupling means particularly adapted for independently 5 supported cars and arranged to connect the cars together so that side sway, rocking, and lurching are materially reduced while accommodating all curvatures and grades in the track. Our invention is particularly concerned with ,10 the provision of coupling means for light weight rail cars for high speed trains having two or more separately supported cars having at least'two trucks for each car, as compared with articulated cars in which three trucks are used to support 15 two cars. According to the principles of our in vention, each coupling device is in the nature of a universal joint which permits the cars to go around curves and up and down grades, but if one car should start to rock or sway, or otherwise 20 shift its position laterally or vertically, such movements are resisted by the inertia of the other car, since the only relative movements per mitted between the cars is that of swinging about 25 the form of a box girder, as best shown in Figures 4 and and 5 gether angles 5, and embodies top and bottom plates 4 suitably spaced apart and connected to by side plates 6 and ‘l and associated 8, all of these plates and angles being se 10 curely riveted together to secure a strong sturdy supporting beam for the car, as is Well known. The car coupling illustrated in Figure l in cludes a ?rst casting or coupling member E0 in cluding a generally rectangular body section II 15 securely riveted, as at 12 and I3, to one end of the car beam I, being thus permanently secured in this manner to the car. The ?rst casting member II] also includes a yoke section I5 which is pro vided with a pair of bearing arms l6 and H carry 20 ing bearing caps l9 and 20 adapted to be secured thereto by bolts 23. In the form of our invention shown in Figures 1 and 4, preferably the sections a horizontal or a vertical axis. I l and I5 are formed as one integral piece or cast Speci?cally, it is an object of the present in vention to provide coupling means for railway mg. cars in the form of a universal joint which per mits the cars so connected to swing about either a horizontal or vertical axis in accommodating 30 curves or grades in the track while imposing upon one car any tendency for the other car to shift vertically or laterally, or rock about a longitudinal axis. A futher object of the present invention is the 35 provision of a car coupler which will force the cars to rock together so that when there arises any tendency for one car to rock, such motion is restrained by the inertia of the other car. These and other objects and advantages of the 40 present invention will be apparent to those skilled in the art after a consideration of the following detailed description, taken in conjunction with the accompanying drawings. 45 Figures 1 and 3. Referring now to Figure 1, the reference nu meral I indicates the central supporting beam of the car. The supporting beam l is preferably in In the drawings: Figure 1 is a side View, certain parts being shown in section, of one form of our invention; Figure 2 is an end view of the left hand cou pling member shown in Figure 1 and the central 50 universal pivot block mounted in position; Figure 3 is a side view of a modi?ed form of our invention in which one of the casting mem bers is made in two sections to facilitate coupling and uncoupling the cars; and Figures 4 and 5 are perspective views of the left 55 25 The second coupling member is indicated in Figure 1 by the reference numeral 25 and simi-n larly includes a body portion 28 disposed between the top, bottom and side plates 4, 5 and 6 of the beam l of the other car and a yoke section 21 30 having its upper and lower ends terminating in upper and lower bearing arms 29 and 30. Like the bearing arms [6 and H, the arms 29 and 30 are also provided with bearings caps BI and 32 35 secured to the associated arms by bolts 34. The third element of the universal joint cou pler in the modification shown in Figures 1, 2 and 4 is in the form of cruciform pivot block 35 having end portions 36, 37, 38, and 39 extending outwardly at substantially right angles to each 40 other. The ends 38 and 39 are arranged to re ceive thrust washers 4! by which the ends 38 and 39 bear against the laterally inner sides of the bearing arms [6 and H. The bearing arms 16 and IT carry circular closure plates 43 to keep 45 dust, dirt and the like from the studs or‘ pins 4!], as best shown in Figure 1. A flange 45 is pro vided on the first casting member l0, and a simi lar flange 46 is carried by the other casting mem ber 25, and these ?anges are riveted to the trans 50 verse channels 48 on which the car floor is sup- ported. As best shown in Figure 2, the pivots 40, as sociated with the ends 33 and 39 of the pivot block 35, provide a horizontal axis about which 55 2 2,128,397 the pivot block 35 can swing. The upper and lower end portions 36 and 31 of the cruciform block 35 are adapted to be received between the bearing arms 29 and 36, as best shown in Figure l, and thrust washers 50 are employed to trans mit the vertical thrust from the cruciform block 35 to the yoke 27. The ends 36 and 31 of the pins or studs 46 described above, carried by the ends 38 and 39 of the cruciform pivot block 35. In this form of our invention coupling and un and 353, being received and journaled for rotation coupling the cars can be easily done by inserting and removing the taper wedges 65 and ‘i5 with out disturbing the pivots of the universal joint itself. While we have shown and described above the 10 in the bearing caps 3| and 32 and the associated portions of the bearing arms. A cap 53 is fas preferred construction in which principles of the present invention have been embodied, it is to be block 35 carry a long pivot pin 52 which is secured in both the upper and lower bearing arms 29 10 described previously, including bearing caps 83 and 84 which receive pivot pins, similar to- the tened, as by a screw, to the upper end of the pivot pin 52 and serves the purpose of keeping the pin 15 52 from dropping out of the bearing arms 29 and 36 and maintaining it against endwise displace ment. It will be noted that the pivot pin 52 and the arms 29 and 30 provide for the swinging movement of the block 35 about a generally verti cal axis as de?ned by the pin 52. Since, in the form of our invention shown in Figures 1, 2 and 4, the yoke sections l5 and 21 are preferably formed as an integral part of the body casting sections l I and 26, respectively, coupling and uncoupling the 25 cars is accomplished by inserting and removing the pin 52. Referring now to Figures 3 and 5, which illus trate another form of my invention, it will be observed that the casting member having the '30 vertical yoke is of the same construction as the corresponding member shown in Figure 1, and for understood that our invention is not to be limited to the speci?c details shown and described above, but that, in fact, widely different means may be 15 employed in the practice of the broader aspects of our invention, as de?ned in the appended claims. What we claim, therefore, and desire to secure by Letters Patent is: 1.

Likewise, the cruciform pivot block the other only about said pivots and to prevent is also of practically the same construction and the same reference numerals have been applied. As far as the pivot block 35 is concerned, in the spect to the other about a generally longitudinal form of the invention shown in Figures 3 and 5, the end portions 38 and 39 are not spaced quite so far apart as in the construction shown in Fig 40 ure 2, as will hereinafter appear. Referring now more particularly to Figure 3, it will be observed that the left hand casting member, indicated in its entirety by the reference numeral 66, comprises two separate sections, a 45 body portion 6| and a yoke section 62. The body section 6! is disposed between the top, bottom and side plates of the car beam in the same manner as has been described above and is securely any relative rotation of one car frame with re axis. 2.
