EDWIN BUSSE, on CHICAGO, ILLINOIS, nssreivonrooIIfcAeoinAIfwAv minimum coMPAnY, 0s CHICAGO, ILLINOIS, aconronnrron or LLInoIs I j BRAKE BEAM SUPPORT Application filed Februa ry 19, 1931. Serial No."51.7,068.

This invention relates to. railway rolling stock and consists particularly in a novel supporting means for brake beams. i

In clasp trucks, the braking force is transmitted to each brake beam through either one or two brake levers according to maximum load requirements. In the first case, the lever is pivotally secured to a fulcrum centrally located on the brake beam and in the second case, the levers are connected to the outerfportions'of the beam. Beams of I sectionare generally used and a short fulcrum arm is usually provided thereon.

The beams are normally supported at each end by hangers depending from suitable brackets on the truck and hooked through the brake heads,but additional support is desirable to'prevent the beam from falling to the track in case one, or both, of the hangers is broken, as well as'to prevent the tilting of the beam. Fourth point supports are commonly used for the above purpose; that is, two additional supports are provided, one

under each outer end of the beam. The supports are usually secured to the spring plank and each support engages a suitable projection or chair on the brake beam.

The main object of my invention is to provide a novel chair particularly adapted for use in connection with fourth point supports.

I attain this object in the structure illustrated in the accompanying drawing in which Figure 1 is a fragmentary top view of a truck embodying my invention and showing is shown as composed of side frames including pedestals 1 and an intermediate recess 2 for receiving a spring plank 8 and the end of bolster 4 which rests upon springs (not shown) A brake beam 5 of I section mounts 50 a brake head 6 at each end, the brake head brake arrangements for car being supported directly from the truck I; 7

In F g 3 and 4., he h r 14 is formed separate y and has bifurcations 14 in the; pp r part thereof which embrace thebifurg cated end of arm16 and are secured thereto lever 15. andaservesto pivotally connect the same with the fulcrum arm. Any otherv suit by a pin 17. Pin 1'? also extends through J able type of pivotal connection between the,

integrally therewith. The .gchair bears directlyagainst a guard, guide, or [supthe spring chain-f arm andlevermay be utilized ifde sired. I V p I modified .device is the same as that of, the form shown in Eiguresl .and2. y I

It will be seen that my novel supporting chair' is located substantially in line withthe The operation and function of 'the brakelever and somewhat forward from the brake, beam itself, thus preventing'the tilting of the beam under influence of wheel ro tation during braking-and of the pre' 'on g derance of weight of beam and parts in front of pivoting point of brake hanger in brake head, and also providing an efiective and easily assembled chair, strut, and lever struc ture.

My invention is primarily adapted for use in connection with fourth point supports of bar type brake beams, but it will be understood that the principles thereof are equally applicable wherever the brake lever engages the end of a strut or fulcrum arm; Furthermore, the support itself need not necessarily be suspended from the spring plank, but may be secured to any other convenient portion of These and other modificathe truck frame. tions may be made in the details of the structure disclosed without departing from the spirit of the invention and I contemplate the within the scope of my claims.

exclusive use of all such variations as come I claim: 1. A fulcrum arm for a brake beam having an end portion arranged for pivotal connec-v tion with a brake lever and having afsupporting chair depending from said portion.

2. A fulcrum arm for a brake beam having a bifurcated forward portion for pivotally mounting-the end of a brake lever, and having a supporting chair ldependingfrom said por;

tion andintegral therewith. l 3. A fulcrum arm fora brake beam comprising a portion adapted to be secured to c i the brake beam, and a portion disposed at an a angle to said first mentioned portion and forming a supporting chair for the beam, the intersection of said portionsbeing arranged to pivotally mount the end of 'a'brake lever.

L 'A supporting chairfor a brake beam 7 heaving-a support engaging surface, and a rportion adapted to engage intersecting ends of abrake beam fulcrum" and a' brakelevenf 5. 'A sup'portingchair for a brake beam having a lower support engaging-surface and an upper bifurcated portion adapted to receiveabrake lever and a brake beam fulcrum between the bifurcations thereof.

In combination, a brake beam, a guard, guide or support member below said beam, a "brake lever, a fulcrum arin projecting'from said beam and having bifurcations disposed on opposite sides of said lever, a supporting chair having a portion overlapping said bi- -furcationsand said lever, and a p'inextending through said portion,bifurcations, and lever and pivotally securing the same together. l [In testimony whereof I hereuntoaffix my signature this 16 day of February, 1931.
