11 Claims.
This invention relates to centering devices for railway car couplers and more particularly to a centering device of the releasable type.
In the past couplers provided with centering devices have been subject to damage during attempted coupling of cars on curves. Since a centering device maintains a free coupler in central position, if the curve on which two cars to be coupled are located is of sufilciently small radius, the mating couplers may not be within their gathering range and may be damaged by jack-knifing or otherwise, as the cars come together. Accordingly, it is an object of my invention to provide a centering device which is quickly releasable from its functioning relationship with respect to the coupler to permit angling thereof to any desired position and thereby enable proper coupling on curved tracks. Another object is to provide a novel releasable centering device for car couplers which is simple in construction and which is automatically locked into normal operative position upon return of the coupler to centered position from a released angled position.
Other objects and advantages of my invention will be apparent from the following description taken in conjunction with the drawings, in which:
Figure 1 is a front view partly in section of a centering device embodying my invention.
Figure 2 is a plan view partly in section, taken along line 22 of Fig. 3.
Figure 3 is an end View of the construction shown in Fig. l, the carrier iron being shown in section.
Figure 4 is a bottom plan view of'the device.
Figure 5 is a view similar to Fig. 3, with the lock member removed.
Figure 6 is a plan view of the centering spring yoke member.
Figure '7 is a fragmentary plan view of the lock member; and
Figure 8 is an end view of the lock member.
Referring to the drawings, there is shown the carrier iron It upon which the resilient supporting mechanism H is slidably mounted. The coupler I2 is carried by this mechanism the various features of which are described and claimed inmy copending application Serial No. 347,342, filed July 24, 1940. The carrier iron I0 is provided with support flanges I3 which are received in recesses i l in the vertical support columns l5. Bolts It secure the carrier iron to the columns and are relieved of vertical load by flanges I 3. Although the carrier iron is shown as a separate member it is to be understood that it may be formed integral with columns l5 without departing from the spirit of the invention. The carrier iron is formed with horizontal top and bottom walls l7 and I3 respectively and a vertical connecting side wall l9. Within the recess formed by these walls is positioned the centering spring 2i each end thereof engaging the space abutments or stop flanges 2i and, 22. Embracing spring 20 is the yoke member 23, the end portions 2% thereof fitting between the ends of flanges 2! and 22 and thus permitting longitudinal sliding of the yoke relative to the carrier iron against the compression of the spring. The yoke is formed with side straps 25 and 26, strap 25 being received within a recess 27 in side Wall l9. The top and bottom walls of the carrier iron are recessed as at 28 and St? to receive side strap 26 of the yoke. It will be observed that strap 26 serves to complete the enclosure of spring 253, precluding entry of any foreign matter into the spring chamber as would interfere with the operation of the device.
The saddle member which is adapted to slide along top wall I! of the carrier iron has depending flanges 3E and 3'! embracing the latter and serving to maintain the saddle in position thereon as the coupler angles in service. Flange 31 being adjacent strap 26 of the yoke serves to hold the latter in place within the carrier iron. At each end of flange 311 there is provided an integral bracket 33 for pivotal mounting of the lock member 39. Lugs fill which project from the horizontally extending body portion 4| of the lock member are adapted to be received by brackets 38, the pivotal connection being made by means of bolts 52 carried in the brackets and extending through apertures in the lugs. Each of lugs is formed with a stop 34 adapted to engage bracket 38 as at to limit upward movement of the lock member when the latter is operated to release the saddle from the influence of spring 20. At each end of the lock member is an operating handle N for manipulation of the device from either side of the coupler.
In order to lock the yoke and saddle from relative movement therebetween so that centering spring 26 will be in operative relation therewith, stop lugs 46 on the yoke and projections 4'! on the lock member are provided. In locked position of member 39 projections it are positioned adjacent the ends of lugs 455, and as the saddle member slides along the carrier iron in response to horizontal angling of the coupler the freely moved along the carrier ironto any angled position of the coupler desired within the range of movement of the saddle member. In this released position of the device the yoke remains stationary as the saddle member is moved along the carrier iron. Handles 43 may be used to move the saddle member in addition to being used to operate the lock member during releasing of the centering device. Furthermore, once the saddle member has been disengaged from the yoke and displaced from central positionhandles 43 which previously had been raised may be dropped to reposed position, after which no further atten- I tion need be given to the lock member, and. the
parts will become locked automatically when the coupler reaches its central position. This action is made possible by sloping the sides of lugs 46 on the yokefrom near the outer ends thereof to the side of strap 26, as at ,38. .Thus with the device disengaged and the saddle moved along the carrier iron so that one of" projections Al is located intermediate lugs 46 and in engagement with the side of strap 26, upon movement of the saddle toward central position, portion 49 of handle 33 or projection 41 will slide along surface 48, causing the lock member to pivot upwards. This raising of the lockmember continues until the saddle reaches central position at which point the lock member will drop into normal locked position with projections 41 in engageable relation with lugs 15, as shown particularly in Fig. 4. It will be observed that in all operative positions of the lock member the preponderance of the weight thereof is located outwardly of pivots 42 and therefore acts to return the member to locked position and to maintain it therein.
' The terms and expressions which I have mployed are used asterms of description and not of limitation, and I have no intention, in the use of such terms and expressions, of excluding any equivalents of the features shown and described or portions thereof, but recognize that Various modifications are possible within the scope of the invention claimed.
