LOCOMOTIVE STRUCTURE Application filed March 16, 1928. Serial No. 262,127.

My invention relates to railway rolling stock and particularly to locomotive structure, and consists in a novel arrangement of the use of the parts referred to without the labor and material required for separately forming and assemblin them and also to eliminate the necessity OI constant inspection of the parts and frequent tightening of their connections in order to maintain their rigid assembly. I

In the accompanying drawings which illustrate a selected embodiment of my invention Figure 1. is a side view of the front portion of the bed or framing of a locomotive illustrating a steam cylinder, steam supply chamber, boiler saddle, brake cylinder and lever, and brackets for the same, pedestal,

dock plate, pilot beam, and coupler pockets Fi ure 2 is a top view of the framing member i lustrated in Figure 1 with some of the other elements sectioned to better illustrate their structure, this section being taken on line 22 of Figure 3.

Figure 3 is a vertical transverse section taken on line 33 of Figure 1.

Figure 4 is a front elevation of one-half of the pilot beam and coupler pocket.

Preferably I combine most of the parts illustrated in a one-piece casting including a locomotive bed with side frame elements 1, connected by transverse walls 8 and 9 which carry the boiler saddle 2. The casting also includes the steam cylinder 3, steam supply chamber 4, steam exhaust passages 5, pilot beam 6, and coupler pocket forming elements 7 The rear transverse Wall 8 has formed integrally therewith angular brackets 10 for mounting the brake cylinder 11 which is separately formed and is of the usual construction. Ordinarily such cylinders are mounted on the top of the transverse members of the framing and therefore are spaced farther from the boiler saddle and closer to the driver axles.

Projecting downwardly from the framing member 1 and transverse walls 8 and 9 is an integral bracket 12 on which the brake cylinder lever 13 may be fulcrumed as indicated at 14. The lever 13 will be operated by a suitable connection 15 to the piston in cylinder 11.

This construction enables the brake cylinon, or GRANITE CITY, ILL NoIs, A conroder to be located closer to the boiler saddle than is possible with the usual mounting previously used,.and the brake lever may be operated without interfering with the front pedestal structure 16.

While I show the saddle and the transverse member of the bed which supports the saddle as being formed inte rally with each other and with the remaimier of the bed, the saddle portion could be made detachable without affecting the advantages derived from mounting the brake cylinder on the transverse member.

The integral formation of the pilot beam 6 with the bed or framing eliminates a large amount of machining and bolting or riveting operations, and the provision of webs or ribs at the center portion of the pilot beam to form the coupler pocket also saves considerable weight and eliminates much drilling and other machining and assembling labor. With this structure, the coupler pocket can be located partly to the rear of the front walls of the pilot beam without weakening the structure and this will result in less projection of the coupler beyond the front of the pilot beam.

It is not essential to the use of other features of my invention that the coupler pocket be formed integrally with the pilot but the pocket member could be formed separately and attached to the front face of the said saddle.

3. A locomotive boiler saddle and a brake cylinder supporting element formed integrally with each other.

4. A locomotive boiler saddle, brake cylinder supporting element, and a brake lever fulcrum bracket formed integrally with each other.

5. A one-piece casting comprising a locomotive boiler saddle With an integral element for mounting a brake cylinder.

6. A one-piece casting comprising a locomotive boiler saddle with integral elements for mounting 'a' brake cylinder and a brake lever.

7 A locomotive boiler saddle, steam cylinder, and air brake cylinder support element all formed integrally.

8. In a one-piece casting for a locomotive, a steam cylinder, a web extending transversely of said cylinder. and an element for mounting a brake cylinder formed on said web.

9. A one-piece casting comprising a locomotive frame member, a steam cylinder, a boiler supporting member extending transversely of said frame member, and a brake cylinder supporting element on said boiler supporting member.

10. In a one-piece casting for a locomotive, a steam cylinder, a member extending transversely of said cylinder for supporting a boiler, and a brake cylinder supporting element on said member.

11. In a one-piece locomotive bed, a steam cylinder, a web extending transversely of said cylinder, and a brake cylinder mounting element on said web.

12. Ina locomotive, framing members, a boiler support located above said members, a transverse wall connecting said support with said members, and means associated with said wall for the attachment of a brake cylinder.

13. A one-piece casting comprising a locomotive driver pedestal, a member extending transversely of the plane of said pedestal, for carrying a boiler, and abrake cylinder supporting element formed integrally with said member.

14. A one-piece casting comprising a locomotive driver pedestal, a member extending including an integral cylinder :lltillt and bumper beam.

17. In a locomotive, a cylinder saddle having an integral forward projection forming a bumper beam.

18. A one piere locomotive bed casting having a pair of steam cylinders and a pilot beam formed integrally therewith, said pilot beam extending laterally from said bed.

19. A one-piece locomotive bed casting having a boiler saddle, a pair of steam cylinders and a pilot beam formed integrally therewith, said pilot beam extending later ally from said bed.

20. A one-piece locomotive bed casting having a boiler saddle, a pair of steam cylinders, steam passages and a pilot beam formed integrally therewith, said pilotbeam extending laterally from said bed.

21. A one-piece locomotive bed casting having a pair of steam cylinders, steam passages and a pilot beam' formed integrally therewith, said pilot beam extending laterally from said bed.

22. A one-piece locomotive bed casting having a pair of steam cylinders and a pilot beam formed integrally therewith, said pilot beam extending laterally from said bed in front of said cylinders.

23. A locomotive bed having an integral horizontally disposed steam cylinder and having an integral pilot beam projecting laterally of the bed in front of said steam cylinder.

24. A locomotive bed including horizontally disposed steam cylinders, pedestals, and a pilot beam projecting laterally from the bed and in front of said cylinders, all integral with each other.

25. A locomotive bed including horizontally disposed steam cylinders at its sides, pedestals, and a pilot beam with its ends extending in front of said cylinders and provided with a coupler pocket intermediate its ends, all integral with each other.

In testimony whereof I hereunto aflix my signature this 29th day of February, 1928.
