BRAKE-HEAD FOR RAILWAY-CAR BRAKE-BE'AMS.

SPECIFICATION forming part of Letters Patent No. 740,092, dated September 29, 1903.

Application Bled July 6, 1903.

To all whom, t may concern,.-

Beit known that I, SETH A. CRONE, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented. certain new and useful Improvements in Brake I-Ieads for Railway-Car Brake-Beams, of whichthe following is a specication.

The invention relates to improvelnents in brake-heads for railway-carbrake-beams and it consists in the novel featuresand combinations of parts hereinafter described,and particularly pointed out in the claims.

Brake-beams of the class towhich my invention pertains comprise a body-beam of suitable length, brake -Vheads on the ends thereof adapted to receive the brake-shoes, and a fulcrum or strut for the brake lever, one division of brake-beams employing a fulcrum and the other or trussed beams comprising a strut; and my invention has for its object to produce a novel brake-head for the ends of the body-beam whether the latter be a structural beam or a flanged beam, the said brake head 4being efficient and capable of being firmly and quickly applied tothe ends of the beam and of receiving and rmly holding the brake-shoes.

The brake-head of my invention is formed from a blank or blanks of forged metal bent to the required shape and adapted to be secured uponthe end of the body-beam and to eectually receive and support the brakeshoe;

The purpose of my invention is to materially improve brake-shoe heads and to produce a brakeshoe head capable of withstanding the severe uses to which brake-shoe heads are put and which shall be efficient and durable and not likely at any time tobecoine fractured or broken.

The invention will be fully understood from.I

Serial No. 164.307. (No model) Fig. 2. Fig. l is aphorizontal section of a `portion of saine on the dotted line et 4 of Fig. 2. Fig. 5 is a detached plan view of a blank employed in the formation of a part of ,one desirable construction of the brake-head. Fig. 6 is a view, partly shaped, of the blank from which the brake-head shown in Figs. l and 2 is formed; and Fig. '7 is an edge view of same.

In the drawings, l0 designates acustomary form of brakeshoe, ll a customary form of body-beam, and l2 the brake-head of my invention, this head being of forged metal and having the shoe lO secured to'it'by means of the pin 13which is of usual form and construction.V p

The brake-head may be described as comprising an inner face portion 14. to receive the shoe l() and an outer face or portion 15 to be applied to the body-beam ll. The inner face or portion of the brake-head is at its ends formed with the bearing-surfaces 16 for contact with the end surfaces of the brakeshoe IO and at its central portion with the bearing-surface 17 for contact with the inner end of the central lug 18 on said brake-shoe, while at the opposite ends of the said bearingsurface 17 the said head is formed with the projecting pockets 19, which lie at the upper and lower ends of the said lug 1S and at their upper and lower ends are open in line with the usual opening in the lug 18, so that the pin I3 may pass through said pockets 19 and lug I8, as shown in Fig. l, for the purpose of detachably fastening the shoe 10 to the brake head. The pockets I9 are formedby slitting the metal blank on the lines 2O 20, Fig. 6, and depressingthe metal of the blank intermediate said lines, rso that said metal thus depressed shall constitute a pocket or loop, this pocket` or loop having a closed outer end where it contacts with the shoe and closed sides, but open at its upper and lower ends, so as to form a passage for the pin 13. respond exactly with each other, and their primary purpose is to afford projections to Contact with the innergface of the shoe IO and to pass into line with the upper and lower ends of the lug 1S of said shoe, so that the pin I3 may be applied for securing the shoe IO in position. In the preferred consame looking in the direction of thearrow in l The pockets or loops 19 I9 cor-I IOO struction of the head I also make use of the loops or pockets 19 and pin 13 as a means for aiding in securing the head and shoe to the body-beam 11, and in carrying out this feature of the construction, which is shown in Fig. 1, I first provide a blank 2l, (shown in Fig. 5,) having projecting' end lips 22 and slits 23, these slits 23 substantially corresponding with the slits formed on the lines 2O preliminar)v to the formation of the loops or pockets 1f?. The blank 21 when prepared as shown in Fig. 5 then has the metal intermediate the slits 23 22S depressed vinto the form of loops 21, corresponding with but smaller than the loops or pockets 19 of the head, and the said loops 2l of the plate or blank 21 are then inserted into the said loops or pockets 19, as shown in Fig. 1, so that they may not only strengthen the said loops or pockets 19, but afford a means for securing the plate 21 against the rear side of the front 1i of the brake-head, said plate when so applied to the head leaving the lips 22 projecting outwardly in position to be turned over upon the flange of the beam 1l, whereby to aid in securing the head to said beam and in rendering the entire structure more rigid and durable. \Vhen the loops 21 of the plate 21 are inserted within the loops or pockets 1f) of the brake-head, a double thickness of metal is provided intermediate the pin 13 and the shoe 10 and also at the opposite edges of said pin, vwhich when in position will lock the plate 21 in its location and enable said plate through its lips 22 to effectually bind against the flange of the beam 11.

The front 14 of the brake-head is about on central lines traversing the pockets or loops 19 formed with shoulders 25, against which the end edges 26 of the plate or blank 21 may Contact, said shoulders 25 formingin effect a recess to receive the body of the plate orblank 21 and aid in securing the latter firmly in position. In instances in which it maybe desired not to employ the plate 2l the recess formed by the shoulders 25 would directly receive the flange of the body-beam 10 and aid in centering the brake-head upon said fiange.

From the lower edge of the lower loop or pocket 1!) of the brake-head the front face thereof curves downwardly and outwardly to the bearing-surface 16, at the lower end of which the plate or blank from which the head is formed is turned upwardly upon itself to form one section ,of the outer face portion 15 of said head, the two portions contacting with each other below the lower loop or pocket 19 and being bound together in the preferred construction by a tongue 27, formed from the metal of the blank and pressed outwardly therefrom and upwardly against the saidouter portion 15 of the said brake-head. The lower section of the outer portion of the brakehead passes upwardly to the web of the beam 11, where it is formed into a flange 28, adapted to be secured to said web and conforming to a flange 29, formed on the upper section of .the outer portion 15 of said head.

From about the upper edge of the upper loop or pocket 19 the inner face 14 of the head is curved inwardly to form the loop 30 and then upwardly and out to the upper bearing-surface 16 for the shoelO, at the upper edge of which surface 1G the metal of' the blank or plate is folded over upon itself and carried downwardly to engage the outer surface of the loop and also to pass into engagement with the web of the beam 10, this portion of the blank being formed integrally with the flange 29, through which and the flange 28 the rivet 3l, for securing the head upon the beam, may pass.

At the upper end of the brake-head is formed the eye 32, to which in the usual manner the suspending-chains may be attached, and this eye 32 is, like the tongue 27, formed from the metal of the blank out of which the entire brake-head is formed. In the formation of the eye 32 and tongue 27 I slit the metal blank on the lines 33 for the eye 32 and on the lines 34 for the tongue 27 and then in forming the blank into a finished head press outwardly those portions of the metal between the slits and between the slits 3J( to form, respectively, the eye 32 and tongue 27.

rlfhe entire brake-head is when the plate 21 is not employed. formed from one strip or blank of forged metal first bent into the preliminary outline shown in Figs. f3 and 7 and then into the finished condition shown in Figs. 1 and lVhen the plate 2l is made use of, the entire brake-head is then formed of but two pieces of forged metal, and in either construction the main body of the head is in one integral piece of forged metal so shaped that it may effectually resist the strains likely to come upon it and to eilieiently and properly receive, support, and maintain the shoe 10.

At the upper end of the head the metal of the blank may be stiffened and strengthened, if desired, by, while cutting the slits 33, pressing the metal at the outer sides thereof outwardly to the position indicated by the dotted lines 35 and then pressing the outer edges of this portion of the metal outwardly to form angle-iron flanges, which will appear in the finished head at the upper end of the latter and at the opposite sides of the eye 32.

The outer portion 1 5 of the head above described is shown as applied to a flanged beam 11; but in the construction of trussed beams the body-beam is in the form of a channel or other structural shape, and when my brakehead is to be applied to this character of body-beams the ends of the blank instead of being brought together to form the fianges 2S 20 to engage the web of a fianged beam will be conformed fo the upper and lower surfaces of the channel or other structural beam without, however, other modifications in the general bodyof the forged-metal head.

I prefer to form tle loops or pockets 19 and 2lin the manner hereinbefore described, so
