BRAKE-BEAM.

EEEUIFICATIQN forming part of Letters PatentNo. 743,498, dated NovemberlO, 1903.

Application filed May 28, 1902. Serial No. 109,278. (No model.)

To all whom it may concern:

Be it known that I, JOHN M. HANSEN, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Brake- Beams; and I do hereby declare the following to be a full, clear, and exact description thereof.

simple in construction, and so formed as to permit the ready attachment of the brakeheads and fulcrum thereto.

In the accompanying drawings, Figure 1 is a plan view of my improved brake-beam. Fig. 3 is an end view of the same, on an enlarged scale, with the fulcrum-casting and brake-shoe heads omitted; and Fig. 4 is a plan view showing a modification.

The brake-beam is composed of a steel plate which is pressed into trough shape, having a back 1 and top and bottomsides 2. I The ends preferably are open, as shown. The 1 top and bottom sides are preferably formed of varying width, being widest at their centers and narrowest at their ends, thus making a trough having a varying depth. This varying depth .of trough may be secured either by having the back 1 straight and the front edges of the sides tapering, as shown in Fig. 1, or by having the front edges straight and the back curved or double-tapered, as shown in Fig. 4, or by having both the back and the front edges curved or tapered. Preferably the edges of the top and bottom sides will be bent outwardly to form flanges 4., and these flanges will preferably be of varying width, as shown, being greatest at the center of the bolster and decreasing toward the ends.

The trough-shaped beam formed of. metal plate, as described, is very light and strong,

; riveted to the beam. The fulcrum-casting 9 likewise is provided with a parallel-faced projection or lug 10, which fits in the troughshaped beam and is riveted therein. It is therefore a very simple matter to securely fasten the brake-shoe heads and fulcrumcastings to the beam.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A brake beam comprising a troughshaped metal beam having integral sides and back and having its front side open, said sides and back being plain surfaces from end to end and said sides having outwardly-projecting flanges of varying width extending along their edges.

2. A brake beam comprising a troughshaped metal beam having integral sides and back and open front side and ends, said sides being plain surfaces of varying width, widest at their centers and tapering toward their ends.

3, A brakebeam comprising a troughshaped metal beam having integral sides and back and having its front side open, said sides being plain surfaces of varying width, widest at their centers and tapering toward their ends and having flanges formed on the edges thereof.

4. A brake beam comprising a troughshaped metal beam having integral sides and back and having the front side open, the sides being plain surfaces parallel to each other, a fulcrum-casting and brake-heads provided with projections or lugs fitting into the open side of the trough, and securing means passing through the sides of the trough and said lugs.

5. In a brake-beam, the combination with achanneled member having a vertical web portion, integral flanges projecting therefrom, said flanges being formed widest at their middle portion, and a brake-lever post projecting into said channel between the said flanges at approximately their widest portion, substantially as described.

6. In a brake-beam, the combination with a pressed channeled memberhaving a vertical web portion, integral flanges projecting therefrom, said flanges being formed widest at their middle portion, and a brake-lever post projecting into said channel between the said flanges at approximately their widest portion, substantially as described.

7. In a brake-beam, the combination With a channeled member having a vertical web portion in substantially a straight line from end to end, integral flanges projecting therefrom, said flanges being formed widest at their middle portion, and a brake-lever post projecting into said channel between the said flanges at approximately their Widest portion, substantially as described.

8. In a brake-beam, the combination with a channeled member having a vertical web portion, integral flanges projecting therefrom at one side only, said flanges being formed widest at their middleportion, and a brakelever post projecting into said channel between the said flanges at approximately their widest portion, substantially as described.

9. In a brake-beam, the combination with a channeled member having a vertical Web portion, integral flanges projecting forwardly therefrom, said flanges being formed widest at their middle portion, and a brake-lever post projecting in to said channel between the said flanges at approximately their widest portion, substantially as described.

10. In a brake-beam, the combination with a pressed channeled member having a vertical Web portion in substantially a straight line from end to end, integral flanges projecting therefrom, said flanges being formed widest at their middle portion, and a brake-lever post projecting into said channel between the said flanges at approximately their widest portion, substantially as described.

11. In a brake-beam, the combination with a pressed channeled member having a vertical Web portion, integral flanges projecting forwardly therefrom, said flanges being formed widest at their middle portion,.and a brakelever post projecting into said channel between the said flanges at approximately their widest portion, substantially as described.

12. In a brake-beam, the combination with a pressed channeled member having a vertical Web portion in substantially a straight line from end to end, integral flanges projecting forwardly therefrom, said flanges being formed widest at their middle portion, and a brake-lever post projecting into said channel between the said flanges at approximately their widest portion substantially as described.

13. In a brake-beam, the combination with a pressed channeled member havin gavertical web portion, integral flanges projecting forwardly therefrom at one side only, said flanges being formed widest at their middle portion, and a brake-lever post projecting into said channel between the said flanges at approximately their widest portion, substantially as described.

14. In a brake-beam, the combination with a pressed channeled member having avertical web portion in substantially a straight line from end to end, integral flanges projecting forwardly therefrom at one side only, said flanges being formed Widest at their middle portion, and a brake-lever post projecting into said channel between the said flanges at approximately their widest portion, substantially as described.

.In testimony whereof I, the said JOHN M. HANSEN, have hereunto set my hand.

JOHN M. HANSEN.
