ARNOLD STUCKI, OF ALLEGHENY, PENNSYLVANIA, ASSIGNOR TO STAND- ARD STEEL CAR COMPANY, OF PITTSBURG, PENNSYLVANIA, A CORPO- RATION OF PENNSYLVANIA.
METALLIC BRAKE-BEAM.
SPECIFICATION forming part of Letters Patent No. 750,732, dated January 26, 1904:.
Application filed January 5, 1903.
To a, whrmt it may concern:
Be it known that I, ARNOLD STUGKI, a citizen of the United States, and a resident of Allegheny, Pennsylvania, have invented certain Improvements in Metallic Brake-Beams, of
which the following is a specification.
My invention relates to that class of brakebeams which is composed wholly or mainly of pressed plates of steel or other wrought metal, the object of my invention being to so construct a brake-beam of this class that it can be made without waste of material or labor and will have the material so disposed in it that each part of the beam will be best calculated to resist the particular strain to which that part of the beam is subjected when in use.
In the accompanying drawings, Figure 1 is a plan or top View of a metallic brake-beam constructed in accordance with my invention, this view showing also the brake-heads applied .to the ends of the beam. Fig. 2 is a face view of the beam. Fig. 3 is a section on the line a a, Fig. 1. Fig. 4: is a section on the line b b, Fig. 2; and Figs. 5 and 6 are sectional views illustrating modifications of the invention.
The beam consists of two members 1 and 2, disposed so as to form a truss, of which 1 is the compression member and 2 the tension member, the two members of the truss being connected together at their opposite ends, but separated at their central portions, by means of an interposed strut 3, which also serves as a hanger for the brake-lever.
Each of the members of the truss consists of a plate bentor pressed so as to. form a channel with upper and lower flanges, those of the member 1 being represented at l and those of the member 2 at 2. Each member of the truss is deepest in its central portion and gradually tapers toward each end, where it is shallowest, and the flanges are graduated in reverse orderthat is to say, they are widest at the shallow ends of each truss memher and narrowest at the deep central portion of the sameas clearly indicated in Figs. 1
and 2. By reason of this construction the end portions of the beam will efi'ectually resist Serial No. 137,828. (No model.)
bending strains exerted at points adjacent to the brake-heads and to which all brake-beams 5 are subjected, while the depth of the beam at the center will enable it to best resist the strains due to the sagging of the beam. This disposition of the metal in the two members of the beam also enables me to form each mem- 5 5 her from a straight plate with a minimum of labor and without any waste of material or expense of cutting, shearing, or otherwise shaping the blank.
The flanged ends of one member of the beam 6 fit within the flanged ends of the other mem her, as shown, and these engaging ends are rigidly secured together by means of bolts or rivets i, which also serve to secure in place the break-head 5, a filling-piece 6 being inter- 5 posed between the flanges of the two members of the beam in order to prevent distortion or crushing of said flanges when the ends of the rivets are being upset by the riveting-machine. Rigid and lasting connection of the 7 brake-heads with the beam is thus insured, and twisting or other displacement of the brake-heads upon the beam is effectually prevented.
The strut 3 may, if desired, consist of a cast- 7 5 ing of malleable iron or steel; but it is by preference formed of a plate of steel or other wrought metal bent into U form, the bend of the U being bolted or riveted to one member of the truss and the open end of the U being provided with laterally-extending flanges 7, bolted or riveted to the other member of thetruss, as shown in Fig. 1.
Although I prefer in all cases to provide each of the members of the truss with flanges 8 5 at both their upper and lower edges, a single flange on each member of the truss may in some cases be sufficient. For instance, the member 1 may have a flange upon its upper edge and the member 2 may have a flange upon 9 its lower edge, as shown in Fig. 5, and instead of disposing the members of the beam so that their edge flanges overlap each other at the ends of the beam said members may be placed back to back, as shown in Fig. 6, or a compression member of the character specified may be combined with a tension member of a different character. Suflicient strength may also be obtained by making the flanges and the depth of either member uniform throughout its length.
I am aware that it has been proposed to construct brake-beams having compression and tension members each consisting of a plate with a hollow central rib struck up therefrom and also that such plates have been deeper in the center than at the ends and that the ribs have been graduated in size. Hence I do not claim any such construction; but
I claim as my invention and desire to secure by Letters Patent 1. A metallic brake-beam having compression and tension members deep in the center and shallow at the ends and having edge flanges projecting therefrom in a direction parallel with the direction of the thrust upon the beam,
substantially as specified.
2. A metallic brake-beam having compression and tension members with edge flanges,
