Specification of Letters Patent.

Patented Feb. 17, 1914.

To all lwhom it may concern Be it known that We, JOHN J. MORSE and vWALTER S. GEMMER, citizens of the.United States, residing at St. Louis, State of Missouri, have invented and discovered certain new and useful lmprovements in Brake- Shoes, of which the following is a specilication.

Our said invention consists in certain improvementsin the details vof construction and arrangement of parts of brake shoes for railway locomotives and cars, relating particularly to the type of shoe provided with reinforcement of steel or other appropriate metal in its back, whereby certain economies and advantages are secured in the construction and use of such a shoe, all as will be hereinafter more fully` described and claimed.

Referring to the accompanying drawings which are made a art hereof and on Which similar reference c arac-ters indicate similar parts, Figure 1 is a longitudinal sectional y view of a shoe of our improved construction in which attaching hooks are shown in whole lines and an attaching lug indicated by dotted lines, Fig. 2 a pla-n View of the back side thereof, but showing the attaching'lug as Well as the hooks in Whole lines for illustrative purposes only, Fig. 3 a detail cross section on the dotted line 3-3 in Fig. 2, the bo-lt being shown therein, Fig. 4 a detail plan View to more clearly illustrate the preferred form of slot for attaching the lug to the steel back, Figs. 5 and 6 an edge and plan view respectively of the end hook for connection with the brake head, Figs. 7 and 8 a side elevation and end view, respectively, of the center lug for key connection with the brake head, Figs. 9 and 10 similar views of a modified form of said lug, Fig. 11 a detail plan View showing a modified form o-f the slots in the steel back, Fig. 12 a similar View of another modified form, Fig. 13 a detail side elevation of ano-ther modification in the form of h1 g for key connection,snch as Will he used with the form of slot shown in Fig. 11, Figs. 14 and 15 a side elevation and end view respectively of another modified form of the center lug, Fig. 16 a side elevation of another fcrm of lug, Fi s. 17 and 18 detail views showing moditicatlons in the arrangement for attaching the hooks, Fig. 19 a sectional' view showing the brake shoe attached to the brake head by the center lug, Fig. 2()

a plan View of the reinforce plate separately, Figs. S21 and 22 detail views showing the use of a multiple of the attaching lugs, and Figs. 23, 24 and E25 details showing another modification in the form of attachment between the lug and the steel back.

In said drawings the portions marked A represent the body of the shoe, B the reinforcing plate or steel back, C end attaching hooks, and D the center attaching lug.

In a general way the construction of the shoe shown is similar to other shoes in common use, the invention residing' .chiefly in the details .of construction. Said shoe is formed to extend across the ange as well as the tread .of the Wheels, although we do not desire to be understood as confining our said invention to this'form.

In referring to the reinforcing plate B as a steel back it will be understood that the term is used in the conventional trade sense and that while the metal of which the plate is composed may be, and probably will commonly lbe steel, yet any duc-tile. malleable, or other suitable metal may 4be used.

One of the leading features of our improved shoe is that it is adapted to be attached to the brake head by any .of .the standard methods and also to be used on either end of said head. In Fig. 1 we shovs7 hooks as the att-aching means, in Fig. 19 a center lug with hooks broken otf and arranged for key in line with shoe, in Fi 22 multiple lugsA and arranged for cross eys, while in Fig. 2, to better illustrate in various for-ms, We show both hooks and a .center lug in position for use. It Will be understood, however, that only one forni need be employed when the shoe is in use. The hooks may be bent out of t-he way, or broken off, when the lugs are in use, and the lugs removed Wvhen a hook is to be used, and, generally, that only the parts needed for the particular use need be left on the shoe, the several means being providedl to adapt a single shoe for use in any of the various positions and by any of they standard methods. By means of this construction a shoe is provided which is reversible and can be used either as a right-hand or a left-hand shoe, and with a lug for attachment (either single or multiple) oneshoe is adapted for use in any position and with any form of attachment common in standard equipment, thus avoiding the necessity of carrying difficult styles in stock to meet different requirements and adding materially to the value of the shoe in luse from an economical standpoint.

Said reinforcing plate, or steel back, B is preferably formed with a portion cut out between the points 10 and 11 on the side which for-afs the flange of the shoe and this portion of the steel back is utilized to form the center lug D. Elliptical holes 25 are formed near each end for the bolts 12, and other holes 13 are formed near thetcenter, being preferably punched downwardly to form inturned project-ions 14, which furnish additional anchoring points for tying the reinforcing plate to the cast metal body of the shoe. Other openings 15 and notches 16 and 17 are formed in the flange side of said plate to afford better anchoring means to ulrliite the steel back and the cast body of the s oe.

The attaching hooks C are of the form best shown in Figs. 1, 5, and 6, and are formed with Openings 18 adapted to embrace the inturned projections 14 of the openings 13 in the steel back, and thus form ka secure connection between said hooks and said back and when cast into the shoe'afford a very solid and safely interlocked connection between the several parts. 'They are also formed with elongated holes 51 to register with bolt holes 50. The hook ends c extend up over the ends .of the steel back or reinforcing plate in position tol engage with the brake head in the usual manner. In

Fig. 17 is illustrated another form wherein the inner end of the shank of hook C is upturned through perforation in steel back B, and in Fig. 18 a space is shown between the upturned part4 and the end of the slot to receive a portion 52 of the cast metal and thus more securely fasten said parts together.

The preferred form'of the lug D is illustrated 1n Figs. 7 and 8, consisting of a steel or other appropriate metal strap, or plate, preferably of the same metal as the reinforcing plate, bent U-shaped and formed with notches 19 in its opposite edges which are adapted to engage or interlock with the edges of the slot in the steelback and are preferably formed extended beyond said notches 19 and with other notches 2O in their edges in the extended portions, which serve l, to interlock with the metal of the body when said body is cast around them. In the preferred form said lugs are interlocked with* the steel back by means of an opening therein as best illustrated in Figs. 2 and'4, of a substantially rectangular form slightly longer in one directionv than the other and extending with the long sides at an angle with the ,edges of the steel back. The legs of the lug are -inserted between the ends of said slot until the notches 19 register with the plate when said lug is turned `to stand square across said steel back with its notches engaged with the edges of the plate surrounding the slot therein and, with its edges abutting shoulders s (Fig. 4) which lstop said lug and afford a bearing therefor in perfect central alinement with the shoe, thereby insuring perfectl connection with the brake head. A secure inter-lockingconnection is thus formed and whenthe metal is cast around the inwardly projecting ends filling the openings in the' steel back flush with its outer face, and further interlocks with the notches 20 therein, a connection is formed which not only supports said lug firmly to the body f the shoe, but also serves to lock the steel back, or reinforcing member, and its center to said body, affording a very secure and at the same time comparatively simple construction.

In Figs. 9 and 10 we have illustrated another forni of centerlug in which vthe lower ends of the lug are bent horizontally, forming horizontatflanges 2l which' extend under the edges of the reinforcing member and 'form a secure inter-locking connection. It will be noted that the flanges 21` are`somewhat below the notches 19 having room for cast metal between the bottom of said reinforcing member and said flanges, which thus have their bearing on cast metal and not on the reinforcing member.

.In Fig. 11 we have illustrated a modified form of slot in the steel back in which a lug such as shown in Fig. 13 may be inserted, the ends of the lugs being inserted through the long sides of thev slot and then the lug y as a whole moved to one side, the slots 53 in the ends of the lugs engaging over the tongues 54. l 4

In Fig. 12 we have illustrated a slightly different form of slot in the steel back with which aform of lug such as shown in Figs. 14 and 15 will interlock.l

-In Fig. 16 we have showna 'center lug formed with a narrower top than base, otherwise substantially the same as the lugs shown in Fig. 14, except that it is tapered to conform to the contour of the recessin the Master Car Builders standard brake head.

In Fig. Q3 we have illustrated another modification wherein the steel back, or yreinforcing member, is formedy with central recesses in its edges and the lug is formed as shown in Figs. 24 and 25 adapted to he spread out to permit the notches 19 to en# gage the ends of said recesses and be then sprung, or bent, inward so as to interlock therewith, the lower ends of the legs projecting into, the cast metal of the body as in the other forms.

`While we have illustrated a single lug it `will be understood, ofcourse, that we may use a multiple of lugs if found desirable and while we have illustrated the lug as positioned so that its opening will extend longitudinally of the shoe, yet it may be placed so that its opening will extend transversely of the shoe.` By such a construction the connection with the brake head can be made by means of a cross pin as well as with a key, both types of shoes and connections being in common use on various railroads. In Figs. 21 and 22 we have illustrated such modifications.

By these various improvements in the construction of shoe it will be readily seen that we have provided a single construction embodying the advantages and capable of the for different specifications.

uses of several different forms in common use, thereby effecting material and practical economies not only in the use, but in the manufacture of the shoe, inasmuch as a single set of dies is sufficient to manufacture a shoe which takes the place of several styles of shoes heretofore used re uiring several sets of dies in their manufacture, all of which are required to be kept in stock to supply the different purposes of such shoes.

The long elliptical holes, or slots, 25 and -51 are for the purpose of covering the variation in the location of the centers of the bolts 12 to accommodate various railway speelications in this particular, which vary as to the distance between the two bolt centers,y

usually requiring different styles of heads By this invention we, therefore, eliminate this objection and adapt the single reinforcing member in this particular for any character of specification. It will also be seen that said reinforcing member, or steel back, has a recess 26 at each end to receive the hooks C and .hold themin proper alinement during moldi ing and also form a rigid connection with the reinforcing member, and prevent said hoo-ks from moving to one side or the other.

Uther modifications in form and detail, apparent to those skilled in the art, are obviously within the scope of our said invention.

Having thus fully described our said invention what we claim as new and desire to secure by Letters Patent is: 1
