RAILWAYBRAKE-BEAII SUPPORT.

Application filed m 28,

This invention relates to improvements in railway brake beam supports, and has particular reference to emergency safety sup porting bars and their connections to the spring plank or other part of a railway car truck, and to a method of forming certain portions thereof. I

An important object of the invention is to provide a safety bar and supporting bracket therefor, of extreme simplicity and lightness in weight without sacrificing the necessary mechanical strength. r v

Another object is to provide sucha bracket from sheet metal, andof such a formation as to be especially adapted for mounting flat bars. V Another object is to provide a novel and simplified blank for the formation of such a bracket from. sheet metal, andto provide an improved methodof producing the same.

Other objects and advantages will be apparent from the following description, refer ence beinghad to the accompanyingdraw: ings, wherein one form of the invention is shown by wayof illustration. i

The invention may be applied to various standard types of railway car trucks such as shown in Figures 1 and 2 wherein a spring plank 10 is provided substantially of'a channel formation and having the usual brakebeam mechanisms disposed longitudinally at its opposite sides. Such a brake beam mechanism includes brake-beam ll,

compression member 12 connectedtogether intermediate their ends by the usual strut 13, as is well understood by those skilled in the art. V I

Mounted below the spring plank 10 and extending outwardly from the sides thereof to be positioned below the brake-beam mechanisms are a pair of emergency safety supporting bars 14; here shown in the form offlat metallic members having a substantially rectangular cross-section and held in place by means of brackets 15. Two brackets are preferably used for each safety bar and said brackets may be secured at opposite sides of the spring plank; as best shown in Figures 1.

to 3. Asall of these brackets are preferably alike a detail description of one will suffice for a complete understanding of the invention.

As best shown in Figures 2, 4, 5 and 6, the bracket 15 includes an attaching portion 16, by which it may be secured to the side flange 17 of thespring plank 1O bynieans of rivets 18 or other suitable fastening members, and a depending body portion 20 integral with said attaching portion. The upper end of the attaching portion 16 may be bent over, as at 21, to more positively hold the device in place and to relieve the. rivet 18 of the weightof the bracket an d the body portion 20 ymay preferably extend inwardly below the spring plank, as best shown in Figures 2 and 4t. Said body portion 20 includes a web member 22 disposed in substantially the same plane as the attaching member 16, and a pair of laterally extending

members

23 and 24 which are adapted to provide flat bearing surfaces for engaging the opposite sides of the safety bar 14. The upper edges 25 of the members 28 and 24: are suitably formed to snugly seat against the bottom of the spring plank 10 in such a manner as to provide a firm mounting of the bracket on the car truck. In order to accommodate the safety bar 14, the

members

23 and 24; are provided with aligned apertures 26 for thereception of a locking member 27, of any suitable form, and the web 22 is provided with an opening 27 of suitable size to permit longitudinal passage of the safety bar therethrouglr The preferreo embodiment of the inven tion contemplates the formation of the bracket 15 from sheet metal and for this purpose the material may be blanked out of the flat stock in the formshown at 28 in Figure 7. new. seen :trmn view that 1y portion 20 is of greater width than the attaching portion 16, the construction being such that the opposite side edges .29 and 30 manner that material from the opening may be inwardly bent, as shown at 83 and 34 in Figure 4;, to engage the. lower and upper edges, respectively, of the safety bar 14. In this manner a substantial, supporting set is formed for the safety bar at 33 and the parts may be so proportioned that the deflected ear at 84 may frictionally engage the upper edge of the safety bar in order to more securely hold the same in the event that the locking member 27 should become lost.

In use a-pair of the bracket members 15 are secured in alignment with the spring plank l0 and thereafter the safety bar ll'may be easily inserted through the aligned openings in the Webs 22 of said'brackets. The safety bar is, of course, suitably apertured for the passage of the locking-members 27, whereby the bar'is held against accidental displacement from its supporting brackets, and the safety bar may easily be removed from the car-truck for purposes of repairs or the like by first removing the locking-members 27 and withdrawing the bar outwardly. It will be evident from the foregoing that an extremely simple supporting bracket has been provided for the safety bars of railway brake beam mechanisms and that the assemblage of such brackets with relatively flat safety bars is particularly advantageous where lightness in weight is desirable. It is also to be not-ed that the safety bar may be supported closeup beneath the spring plank, and since nopart of the bracket extends outwardly any substan tial distance from the spring plank, the combin ati on of parts may be used where space for mounting the same is limited. In view of the improved method of forming the brackets, theymay be economically manufactured, and thesimplicity of construction has been effected without sacrificing any of the necessary mechanical strength of the parts. The blank28 may be. formed in any suitable man ner such asby punching, shearing, or the like,

- and in the event that it is punched out by means of dies, the slitting at 31 and 32 and the deflection of the

portions

33 and 34; may be accomplished in the same operation if desired. Also the bending of the

side portions

23 and 24 may becarried out simultaneously with any or all ofthe other steps of the process, will be obvious to those skilled in the art.

The invention is of course susceptible of modifications in the details of construction and in the steps of the method of producing the bracket, and the rightis herein reserved to 1 make such changes as fall within the scope of the appended claims without departing from the spirit of the invention. c
