Description

Get. 16, 1928.
1,688,174 H. A. F CAMPBELL LOCOMOTIVE CYLINDER STRUCTURE Filed NOV. 18, 1927 Patented Oct. 16, 1928.
UNITED STATES HARRY A. F. CAMPBELL, OF PHILADELPHIA, PENNSYLVANIA.
LOGOMOTIVE CYLINDER STRUCTURE.
Application filed November 18, 192?. Serial No. 234,174;
My invention relates to certain improvements in locomotive cylinder structures, of the type in which the live steam pipes are outside of the main cylinder structure.
5 Heretofore, these pipes have been separate units, the same being secured to necks on the cylinder structure and to the steam pipes in the smoke-box of the locomotive. This necessitated accurate fitting of the gaskets to prevent leakage.
The object of my invention, therefore, is to make these outside steam pipes integral with the cylinder casting, obviating any joints and dispensing with packing and 1 gaskets.
In the accompanying drawing: Fig. 1 is a transverse sectional view through the cylinder structure, boiler and frame of the locomotive on the line 11, 20 Fig. 2; and
Fig. 2 is a side View.
1-1 are the two side frames of the locomotive, and 2 is the boiler. 3 is the cylinder structure made in a single casting, or in two castings bolted together in the usual manner. This structure rests directly on the frames 11 and is bolted thereto inany suitable manner.
Cast integral with the cylinder structure are the cylinders 4 4 and valve-chests 5--5 of the usual type. n'iunicate in the ordinary manner through passages with both ends of the cylinders AH, and the exhaust passages 66 communicate with the valve-chests 55, passing through trunks 7 extending from the valvechests to the centre of the structure. These exhaust passages 66 communicate at their outer ends 6 with any suitable exhaust nozzles.
8 is the saddle of the cylinder structure, cast integral with the cylinders and sup- The valve-chests com' ported not only by the trunlrsof the upper passages 6 but by ribs 9, as clearly shown in Fig. 2. On this saddle rests the boiler 52.
Cast integral with the cylinder structure and extending from the valve-chests 5 to the saddle 8 are the live steam pipes 10. These pipes not only materially strengthen the saddle at its outer ends but also provide a jointless communication between the steam supply pipes 11 in the smoke-box 12 of the boiler and the live steam spaces of the valvechests. This construction also obviates the cutting of additional holes in the shell of the smoke-box.
By this arrangement the saddle can be readily mounted on the frames, and the boiler can be mounted on the saddle, which is complete in itself, including both the inside exhaust passages and the outside steam passages, these passages being open on all sides, thus allowing for inspection, or repairs in case of leakage, and can be readily enclosed within suitable lagging, if found necessary.
I'claim:
l. A locomotive cylinder structure, having valve-chests; a saddle on which a boiler is located; internal exhaust passages; and out
