ANTIFRICTION COUPLING-CARRIER.

Application filed February 18, 1915.

This invention relates-in general to rail-l wav dralit rigging and morespecilically to an uanti-friction carrier tol support the shank of the coupler.

ln railway cars, as usually constructed, the coupler shank is slidably supported on a. carrier iron secured to the sills of the car.

The constant movement of the coupler, when the ear is in use, rapidly abrades the shank at its point et contact with the carrier 1ron so that it becomes weakened and unfit for .use and the entire coupler must frequently he replaced, although the parts other than the shank may be stillin good condition.

lt is the object ot our invention to pro vide means for supporting the coupler shankso 'that it is not subjected to abrasion,v whereby the lite of the coupler is materially prolonged. p

Other objects and advantages of our invention will be apparent as it is better understood by reference to the 'following specification taken in connection with the accompanying drawings in which- Figure 1 is a vertical section through a portion ot' a car body on a line transversely thereof showing` our invention; installed; Fig. 2 is a vertical section throughthe device on a line normal to the line of Fig. 1; Fig. 3 is a vertical section similar to Fig. l, showing a slightly different form of our invention, and Fig. 4 is a vertical section similar to Fig. 2 ot the form of our 'invention shown in Fig. 3.

Referringr to Figs; 1 and 2 of the drawings, 1 indicates the sills of a car and 2 a carrier yiron secured in any suitable manner to 'the sills. Slidably mounted upon th'eca'rrier iron. 2 is a plate 3 having side flanges t .extenfling downwardly on either side of the y carrier iron Q, to prevent sidewise movement 'of the plate with respect to the carrier iron, A bolt 5, passingr throughthe 'iangcs ','holdsthe plate 3 in coperative relation with the carrier iron 2. The plate 3 is provided with downwardly extendingl ribs G which act retainers for the antiy Specification of Letters Patent.

friction rollers 7 loosely mounted between the plate 3 and the carrier iron 2. As will be readily understood, the plate 3 is movable longitudinally of the carrier iron 3 and frictional contact between the plate and the/carrier iron is prevented by the rollers 7. A plate 8 is superposed upon the plate 3 and is provided with downwardly extendingy flanges 9 to engage the movement with respect thereto of the plate 8 in -a direction longitudinally of the carrier iron`2 and with upwardly/.extending flanges 10 to engage the sides of the coupler shank' 11 and hold it in proper relation therewith. The flanges 10 are slightly cut away at either end of the plate 8,'as indicated in dotted lines in Fig. 1, to allow for slight angular movements of the couplershank 11 with respectI thereto. The plate S is provided with downwardly extending ribs 12, which act as retainers for the anti-friction rollers 13, loosely mounted between the plates 8 and 3. A bolt 14 is disposed in a suitable opening in the plat-e 8 and passes through a slot l5 in the plate 3, whereby the plate 8 is held in coperative relation with the plate 3, the

8 with respect to plate 3 beingT limited the length of the slot 15. It will be 'understood that the plate 8 is movable with respect to the plate Il in a direction normal to the longitudinal axis of the carrier iron 2 and that frictional con- Ifact between the The operation of the device will, it is `thought, be apparent without further description of the structure thereof. ll/hen the car is in use the coupler shank l1 moves both longitudinally and transversely with respect to the car bodv. When the coupler shank 11 moves longitudinally of the car plate 8 will roll upon the plate 3, the movement being, however, limited by the slotd cooperating with the bolt 14. coupler shank 11 moves transversely with respect to the car body, the plate 3 will roll upon the carrier iron E2, the movement in this case being limited by the sills 1. lt will be understood, therefore, our invention all abrasion due to frictional Contact between the coupler shank and the carrier iron is eliminated and that, therethe wear which has been an inherent defeat in att rigging as heigetofore constructed pviated. y In 2F11;` and 4l we have shown a slightly plate 3 and preventl the v When the that by the use oi plates 8 and 3 is prevented irc dierent 'form of our invention in which the carrier iron 16 is provided with downwardly extending portions 17 and a portion 18 inelineddownwardly from either side towardthe renter.- ln this form of our invention the plate 3 is provided with downwardly extending flanges t and a bolt 5 is disposed therethrough to hold the plate in cooperative relation with the portion 418 of the carrier iron 16, as in the form previously described. The rollers 19 are journaled at 2O in the flanges 4 and therefore remain in their proper relative vpositions regardless of the inclined surface of the carrier iron. The

vplate 8 is provided with downwardly extending anges 21 to prevent movement thereof with respectto the plate 3 in the direction of the longitudinal axis of the carrier iron and is further provided with inwardly extending flanges 22 which engage beneath the plate 3 and hold the plate in proper coperative relation therewith. The rollers 23 are journaled at 9AY in the flanges and are, therefore, always re tained in their proper relative positions.

The. plate 8 is, however, providedwith vdownwardly extending ribs 25 on its two.

Y and the downwardly extending portions 17 ot the carrier iron 'i6 act as stops to limit the movement of the plate 3- longitudinally of the carrier iron. f

it will be apparent that various changes may be made in the form, construction and arrangement oi the parts without departingr from the spirit and scope ot' the invention or sacrificing any of its material advantages, the forms hereinl'iefore disclosed being merely preferred embodiments thereof.
