BRAKE-BEAM FOR RAILROAD-CARS.
SPECIFICATION forming part of Letters Patent No. 503,263, dated August 15, 1893.
Application filed April 11, 1 8 9 3 To (ZZZ whom it may concern.-
Be it known that I, FRANCIS J. Gone, a citizen of the United States, and a resident of Baltimore city and State of Maryland, have invented certain new and useful Improvements in Brake-Beams for Railroad-Oars, of which the following is a specification.
My invention relates to an improvement in brake-beams used in applyingthe brake-shoes or rubbers to Wheels of railroad cars and other rolling stock, and provides a strong rigid trussed-beam,wl1ich can be easily and cheaply constructed and through which the brakingforce applied through the brake-lever can be transmitted to the wheels with but little deflection or lost motion. Heretofore brakebeams have been made in many diiferent forms of greater or less complication. The great desideratum in a brake-beam is simplicity, strength and cheapness of construction. These objects I attain by making a beam of rolled angle iron of various shapes, securing a malleable iron head upon both ends and bracing the two ends of the beam by a suitable truss-rod and abifurcated king-strut.
The novel features of my invention consist of the use of straight sections of angle-iron or steel of varying shapes, (I or U shapes being preferred) as the brake-beam cast-heads secured to the extremities thereof, to which the brake-shoe-heads may be directly bolted in the usual manner; a truss-rod secured to the brake beam -head at a point between the brake-shoebolts and the king-strut, so as to leave a clear passage for the brake-shoe-bolts in the extremities of the brake-beam-heads. The truss-rods are secured to the brake-beamheads and the king-post or strut in various ways. The bifurcated king post or strut serves a double purpose, that of separating the compression-member and the extensionmember, and upon which the strain is distributed, and also the purpose of carrying a hearing for the brake-lever which passes through the center of said strut. This strut is constructed in a peculiar manner; it is seated at the end next the truss-rods in a socket in which it will turn, but which is provided with clamping-devices by which it may be rigidly fixed in the socket at any desired angle. The end next the brake-beam is secured to the brake-beam by means of a bolt which, when Serial No. 469,945- (No model.)
parts used in other connections or a broken part replaced or the parts may be readjusted by tightening up the struts.
In the drawings Figure 1 is aplan view of one form of brake-beam and truss-rod. Fig. 2 is a top view of the same. Fig. 3 is a vertical section of the brake-beam and truss-rod, showing a full side-elevation of the king-strut. Fig. a is a plan view of a different form of brakebeam, brake-beamhead, truss-rod-attachment and means for securing the same to the kingstrut. Fig. 5 is a bottom view of the brake beam-head and a portion of the brake-beam and truss-rod. Fig. 6 is still another modified form of the brake-beam-head and means of attaching the truss-rod to the same. Fig. 7 is a bottom View of the same. Fig. 8 is aplan View of another form of brake-bar and head, the brake-bar being composed of a U-shaped channel-iron. Fig. 9 is a section of the channe1-iron used in Fig. 8. Fig. 10 is asectional view of the channel-iron and head or block. Fig. 11 is a vertical section of the end of the brake-beam and head, and side-elevation of the brake-head and shoe, showing the means of attachment of the brake-head to the beam. Fig. 12, is a plan view of another modified form of beam and head and showing a modified method of introducing the truss-rod. Fig. 13 is a rear view of the same. Fig. 14. is a side elevation of the king strut showing the brake-beam and truss-bar in section.
Referring to Fig. 1 A represents the brakebeam made of a piece of I shaped iron; this beam is generally made straight; if desired, however, it may be bent a little in the center; on either end of the brake-beam there is placed a malleable iron head B into which the beam A fits; the headB is perforated as shown in Fig. 2 with two bolt-holes Z), at right angles to its front and rear surfaces, the other If at an angle of about forty-five degrees; it is also provided on its upper side With a boss or lug 12 through which the diagonal hole passes.
O is the king-strnt or post, whichis bifurcated in its center at D, but said bifurcation is closed at both ends. At its upper end it is perforated and through the hole thus formed a bolt E passes and also through ahole in the center portion of the I iron of the brakebeam. By this hole the king-strut may be rigidly secured to the brake-beam at its up per end. The strut is constructed in two parts, the bifurcated portion OO and aing of Whichthe socket may be rigidly clamped upon the lower end of the kin g-post. Through the" centers of thetwo portions of the king- 3 posts 0 and O are holes J -.I which form bearings for the pivot of the brake-lever. It will be observed that, when the bolts E and I are; loosened the king-post may be rotated upon its axis and placed at any desired inclination,
thus giving any desired angle to the brakelever; the bolts E and I may then be screwed up and the post clamped rigidly in the desired position.
holein the bottom of socket F and the ends pass through the inclined holes I) in the ends of the brake-beam and are held in place by bolted to them.
' Referring to Fig. 4, the form of brake-beamhead B shown in that figure differs from that of Fig. 1 and the truss-rods K also differ somewhat in their method of attachment to the brake-beam-head and also to the foot of the king-post. In this case the brake-beam-head is not perforated entirely through by a hole for the truss-rod, but is simply provided with i a socket on its front side into which the head of the truss-rod fits and which is cut away on the upper side so that the brake-beam A mayenterthe head above the head of'the truss-rod, and thus the perforation of the brake-beam for the passage of the truss-rod is avoided. The truss-rod is divided into two parts, and nuts are screwed upon the ends 10 where they pass through holes in a casing F on the lower end of the socket F of the king-post.
Fig. 5 is a bottom view of the structure shown in Fig. 4.
Fig. 6 shows a still further modified form in which the brake-beam-head B is perforated with a socket 16 The truss-rod K passes into the head through a hole 10 and intd the socket k where it is screwed into a nut in which has been placed in said socket. Fig. 7 is another view of the same.
Fig. 8 shows the brake-beam made of a U-shaped channel-iron, shown in section Through I in Fig. 9, preferably pressed or struck up out of plate steel. The brakebeam-head B consists of a block which is fitted into the U or channel-iron, filling the same, and which 7 is bolted to the channehiron by bolts b b The head B4 is shown in section in Fig. 10. In the rear side of said block is a notch b and from it a perforation b passes through the end of the block, through which passes the truss-rod K In this case as in all other forms, the truss-rod is secured to the head B at a point between the center of the brakebeam and the point where the bolt for the brake-head passes through the brake-beamhead.
Figs. 12, 13 and 14 show still another fmodified form of brake-beam, which consists of two parallel bars of metal which constitute the compression-member, and which may be bolted together if desired.
In this specification the caps or fillings on the ends of the brake-beams are called the brake-beam-heads. The truss-rods, sometimes one rod and sometimes two rods, are
1 called truss-rodsyand the portion of the K is the truss-rod which passes through a.
brake-shoe which is secured to the beamheads are called brake-shoe-heads.
An important feature of my brake-beam is the simplicity of the combination of a piece of straight rolled iron, a head and a bolt through the head by which to secure the brake-head in the same way in which it has been heretofore secured to a wooden beam. My beam becomes a complete substitute for the wooden beam from this fact, while the straight piece of rolled iron gives the requisite strength and the head a sufficient body of metal to which to attach the truss- .rod and the brake-head.
What I claim is 1. In a brake-beam the combination of a brake beam, truss rods and king -post, the king-post consisting of two parts, a post and a socket therefor, said socket being provided with means for rigidly clamping the post in the socket in any desired position.
2. In a brake-beam the combination of a brake-beam, truss-rods and king-post, said king-post being constructed in two parts, a post and a socket, s'aidsocket being provided with means for clamping it upon the post in any desired position, the other end of said post being secured to the brake -beam by means of an axial bolt, which may be loosened and tightened to allow a change of position of the king-post and its rigid fixation in any desired position.
3. In a brake-beam the combination of a brake-beam consisting of a U-shaped channel-iron, a king-post secured to the center of the brake-beam, and a truss-rod secured to the two ends of the brake-beam and passing over the extremity of the king-post.

In a brake beam the combination of a brake-beam consisting of a U shaped channel-iron, a head secured to either end thereof, a king-=post secured to the center of the brake-"beam, and a truss-rod secured to the the beam and truss-rods, provided with heads two heads of the brake-beam and passing or nuts on one end which are secured in sockover the extremity of the king-post. ets in the under sides of the beam-heads, the 5. In a brake-beam the combination of a other ends of which pass through the lower brake-beam consisting of aU-sl1apedchanend of the strut and are secured thereto by nel-iron, a head secured to either end therenuts. of, consisting of a block of metal fitting the Signed at Baltimore city and State of Marychannel-iron and filling the space between land this 27th day of March, A.
