HENRY ZIEMSS, JR., 0F CHICAGO, ILLINOIS.

BRAKE-BEAM.

To all whom 'it may concern:

Be it known that I, HENRY ZInMss, J r., a citizen ot' the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Brake-Beams, of which the following is a specification.

One of the objects of this invention is to improve the construction of the brake-head supporting means in brake beams.

Another object is to provide improved means for adjustably securing the brakehead to the beam. In the accompanying drawings, Figure 1 1s a fragmental view of one end of a brake beam embodying the features of my inven tion, the brake head being illustrated in operative relation to the beam. Fig. 2 vis a section substantially on dotted line 2 2 of Fig. 1.

The beam which I have selected for the purpose of illustrating the invention is formed from an I-beain and is indicated by the numeral 1 in the drawings. A portion of one transverse web or head 2 of the beam at each end of the beam isbent to lie within a sleeve 3. Said sleeve is slotted at 4 for the admission of the central web 5 of the beam. The slot 4 does not extend entirely through the sleeve, but stops at the point indicated by 6 in Fig. 1. The beam 1 is notched at 7 to receive the closed end of the slot 4. At the imier end o1c the sleeve 3 are two ears 8 adapted to lie at opposite sides of and in Contact with the central web 5 of the beam, a rivet 9 or equivalent means being passed through said ears and web to secure the sleeve to the beam. The brake head 10, in this embodiment, has a hub 11 which is removably fitted uponthe sleeve 3. At the inner end of the brake head, a slot 12 is formed to receive the central web 5 of the beam when the head is being placedupon said beam. On the brake head and at opposite sides of said slot are formed lugs 13 through which a bolt 14 extends. An opening 15 is formed in the central web of the beam of sufcient size to permitl the ears 13 and bolt 14 to pass through it when the head is being adjusted in position. The hub 11 is cut away at one side, as at 16, suitciently to permit of the desired degree of pivotal movement of the brake head. The cutaway portion 16 is in eEect a continuation of the slot 12. f

As shown in Fig. 1, the cut-away portion Specification of Letters Patent.

Application filed October 21, 1908.

Patented Nov. 16, 1909.

Serial No. 458,805.

' 16 does not extend through the outer end of the hub 11 in order not to weaken the brake-head unduly. The brake-head is fun ther strengthened by the bolt 14. The pivotal movements of the brake-head upon the sleeve 3 arer limited by the engagement of the edge walls 17 with the central web 5 of the beam. The sleeve 3 has an annular flange 18 upon its inner end against which the brake-head is arranged to lie.

The means for locking the brake-head in position upon the sleeve comprises, in this instance, a block 19 corrugated upon its inner surface to engage corrugations 2O upon the periphery of the hub 11. The block 19 has a stem 21 which extends through an elongated opening 22 in the hub 11 into a recess 23 in the sleeve 3. It will be seen that when the block 19 is in engagement with the corrugated surface 20 the brakehead 10 is held against rotation upon the sleeve 3. The means herein showrr for thus holding the block in engagement with the brake-head will next be described.

A bolt 24 extends through an opening 25 in the block 19 and the stem 21, the head of said bolt preferably lying outside of the brake-head. A coiled spring 26 presses at one end against av suitable portion of the sleeve 3, such as the web 27, and at its other end against a washer 28 underneath the nut 29 of the bolt 24. The nut is held against rotation by means of lugs 30 on said washer. The washer in turn is held against rotation by means of lugs 31 thereon which extend into slots 32 formed in the portions 33 of the sleeve 3. The bolt 24 may be held against rotation in any suitable way, as, for example, by means of a lock washer 34.

Assuming the bolt 24 and the block 19 to be removed from the beam structure, the brake-head is placed upon the beam by slip ping said head over the sleeve 3. The bolt 14 is then passed through the lugs 13, the block 19 placed in position with its stem in the recess 23, and the bolt 24 passed through said block and engaged with its nut 29.

Then the parts are in the position shown in Fig. 2, the brake head is yieldingly or self-adjustably held against rotation upon the sleeve, the block 19 yielding downwardly to permit the corrugated surface 20 to move past it in either direction. If it be desired to lock the brake-head rigidly against movement upon the sleeve 3the bolt 24 is rotated until the lugs 31 on the washer 30 are drawn against the lower end Walls of the slots 32, thereby preventing movement of the locking block 19. T he stem 21 of said locking block serves to prevent displacement of the brakehead longitudinally of the beam.

It is obvious that the means herein shown for adjustably securing the brake-head to the beam may be employed in beams of various constructions, and that modifications of the construction here illustrated will occur to those skilled in the art7 Wherefore I desire not to be limited to the details of construction shown and described.

I claim as my invention:

1. A brake beam comprising a beam having a web, and a sleeve slotted to receive said web and secured to said web.
