MOUNTING FOR BRAKE GEARS.

Application filed February 11, 1926. Serial No. 87,594.

My present invention relates to means for mounting a brake operating gear at the end of a railway car, and it has more particular reference to a mounting that may be readily attached to a car end-sill of channel-section. With the principles of the present device the mounting may be readily secured to the end-sill whether the channel has its flanges extendin outwardly or inwardly with respect to t e car, and the mounting structure is firmly braced against the stress incident to the pull of the take-up chain of the brake mechanism so that the mounting and gears are not liable tobecome loosened or accidently detached. I do this by providing an abutment or stop on the casting forming a part of the mounting which stop element contacts the outer surface of the web of the sill and by installing a reinforcement gusset that projects transversely from the rear of the sill to which inwardly extending portions of the casting are secured.

I prefer to carry out my invention and to accomplish the several objects thereof in substantially the following manner, reference being made to the accompanying drawings that form a part of this specification.

In the drawings Figure 1, is a top plan of the mounting structure secured to an end-sill of channel section with the flanges'projectinginwardly.

Figure 2 is a right-hand end view of the structure with the sill in vertical transverse section.

Figure 3 is a vertical front view of '-the structure shown in the preceding figures.

Fi re 4 is a view similar to Figure 3 showing the application of the mounting to an end-sill having channel section and with the flanges projecting outwardly, the sill and gusset being in horizontal section.

Figure 5 is a right-hand end view of the structure with the sill in vertical section and the bottom casting omitted.

f Figure 6 is a vertical front view of the mounting detached from the sill.

Figure" 7 is a side elevation of a modified structure.

The drawings illustrate typical or preferred embodiments of my invention, and' so far as practicable ;I have employed similar reference characters to designate like parts wherever the same appear throughout the several views. y 1

The sill at the end of the car, in Figs. 1,

2, and 3 is a channel beam with its web 10 vertically disposed and with lateral top and bottom flanges 11 and 12 extended inwardly or towards the center of the car. Secured to the inner face of this sill and extending longitudinally of the car is a triangular shaped gusset 13 formed from a metal plate its vertical horizontal and inclined edges providedwith lateral flanges 14, 15 and 16 respectively, for the purpose of strengthening the gusset, said vertical flanges 14 being riveted or otherwise secured to the web of the sill and the horizontal flange 15 resting upon and extending inwardly from the-bottom flange 12 of the sill,

The mounting structure in which the gear members are journaled comprises top and bottom castings that provide bearings for the respective rotative members of the gearing. The top oasting consists of a horizontally disposed rectangular shaped plate 17 that is secured to the under side of the lower flange 12 of the sill and projects out wardly therefrom, and intermediate its edges it is provided with upstanding stops 18, 18, upon its upper surface that are each reinforced by inclined webs 19, 19, so as to brace said stops against the outer front surface of the web of the sill along the lower edge thereof. Extending inwardly from the opposite edge of the plate 17 is a tapered horizontal extension 20 that is approximately the length of the horizontal flange 15 of the gusset and is riveted or otherwise secured to said flange adjacent the inner end"'thereof Thus the top casting is braced against the longitudinal pull of the brake gear winding chain, which exerts a. stress longitudinally of the car, and it is reinforced against tilting by the provision of the gusset plate 13.

The end edges of the plate 17 are provided with lateral depending flanges 21, 21, that over-lap and are secured to lateral upstanding flanges 22. 22, upon the adjacent end edges of the horizontal plate 23 of the bottom casting. Formed integral with the plate 23 of the bottom casting is a bracket arm 24-. that extends inwardly longitudinally of the car and in a plane below the plane of the plate 23, as will be seen in Fig. 2 of the drawings. This bracket arm is parallel with, but slightly shorter than the tapered extension 20 of the plate of the top casting and aflords therewith a dependable structure for supporting and journaling one of the elements of the gearing device.

In Figs. 4, 5, and 6 the web 10 of the sill is vertically disposed but the lateral top and bottom flanges 11 and 12 project outwardly of the car instead of inwardly as heretofore described so that it is necessary to slightly alter the constructure of the bracing members' The plate 17 of the top casting fits against the under surface of the lower flange 12 of the sill and said plate is provided with a stop or abutment in the form of a shoe 25 that extends longitudinally of the plate and is vertically positioned so as to fit against the web. of the channel sill. The shoe has an undercut or recessed portion 26 that is slightly inclined and is spaced a slight distance from the plate so that the lower flange 12 of the sill may be inserted therein as will be seen in Fig. 5. The web of the shoe 25 is riveted or otherwise suitably secured to the web of the sill and there are bracing struts or fins 27 extending from the upper edge portion of the shoe in an outward direction along the undercut or recessed portion and on the upper surface of the plate 17 so as .to strengthen the structure. The. gusset 13 and the remaining portions of the top and bottom castings are substantiall the same as the corresponding parts in t e first de-' scribed form of the structure, and therefore need not be again described.

' In the modification shown in Fig. 7 the top plate 17 of the housing is provided with an upright integral abutment of stop 30' having inclined reinforcement webs 31, which stop 30 fits against and is riveted to the rear or inner face of the end sill 10. The top plate 17 is riveted to the lower flange 26 of the end sill 10, which latter is channel-shaped and positioned with its flanges projected outwardly similar to those of the sill shown in Figs. 4, 5, and 6 last described.

What I claim as new is 1. In combination with a car end-sill of channel section, of a gusset secured to the; end-sill and extending inwardly therefrom longitudinally of the car, a top casting consisting of aplate disposed underneath the lower flange of the sill an extension projecting inwardly from said plate and connected to said gusset, an upstanding member on said plate outside said sill and engaged therewith and a bottom casting connected to said top casting and cooperating therewith to mount a gearing mechanism between the same. I
