UNITED STATES HARRY S. BURNHAM, OF SCHENILCTADY, NEW YORK.
LOCOMOTIVE.
Application filed September 8, 1927. Serial No. 218,160.
This invention relates to the cylinder structure of three cylinder steam locomotives, and is an improvement upon that for which Letters Patent of the United States No. 1,589,362
were granted to the instant inventor, Harry S. Burnham, under date of June 22, 1926.
The objectof the invention is to provide simple and readily applicable means, whereby water which may be be commingled with the steam incoming to the cylinders of the locomotive, will be diverted from the middle cylinder into one of the side cylinders, from which it may be discharged more readily, and with'less liability to effect an injurious result, than if permitted to enter the middle cylinder.
The improvement claimed is hereinafter fully set forth.
In the accompanying drawing: Figure 1 is a front view, partly in section through the side cylinder steam inlet passages and distribution valve chests, of the cylinder saddles of a three cylinder locomotive, embodying the invention; Fig. 2, a right hand side View, in elevation, of the same, and; Fig. 3, an axial section, on an enlarged scale, through the steam inlet passages of the right hand cylinder, and through the valve chest thereof, on the line III, III of Fig. 1.
It has been found, in practice, that, at times, water is mingled with the incoming steam, and the middle cylinder, being inclined, is more difficult to drain than the horizontal side cylinders. Moreover, damage to the middle cylinder, or to its associated members, resultin from the presence of water in said cylin er, is expensive to repair, by reason of the comparative inaccessibility of the parts. The present invention is designed to provide a straighter and more direct passage for the steam to an outside cylinder than to the middle cylinder, so that water that may be carried with the incoming steam, will be separated from the steam, when passing to the middle cylinder, and tend to enter the passage to one of the side cylinders, from which it can be more readily and safely discharged.
In the practice of the invention, referring descriptively to the specific embodiment there- 50 of which is herein exemplified, the middle cylinder, 1, and the right hand cylinder, 1 are, as heretofore, formed integral with a right hand saddle casting, 2, and the left hand cylinder, 1 is formed integral with an abutting left hand saddle casting, 2". The two saddle castings, when firmly bolted together, form a bed plate, which is suitably shaped at its top to receive and support the smokebox of the-locomotive boiler, and is adapted to be secured, at its bottom, to the frame members of the locomotive. Distribution valve chests, 3 and 3 are formed in the right hand saddle casting, 2, adjacent to the cylinders, 1 and 1, respectively, and a distribution valve chest, 3", is formed in the left hand saddle casting, adjacent to the cylinder, 1
A steam inlet passage, 4, is formed in the right hand saddle casting, 2, adjacent to its outer side, and a steam inlet passage, 4", is formed in the left hand saddle casting, 2", adjacent to its outer side. The inlet passage, 4, is divided by partition walls, 4 and 4 into two branches, 4 and 4, one of which, 4*, leads into the distribution valve chest, 3, of the middle cylinder, 1, and the other, 4, leads into the distribution valve chest, 3, of the right hand side cylinder, 1. The steam inlet passage, 4", of the left hand saddle casting, 2, leads into the distribution valve chest, 3', of the left hand side cylinder, 1", in the usual form.
As clearly shown in Fig. 3, the steam inlet branch, 4, leading to the right hand side cylinder, is directly in line with the flow of steam from the main inlet passage, 4, while the inlet branch, 4", leading to the middle cylinder, is located at one side of the branch, 4, and is partially separated therefrom by an upper deflecting partition wall, 4 extending downwardly, and inclined towards the branch, 49, and a lower deflecting partition wall, 4, extending upwardly and inclined in the opposite direction. The lower partition wall preferably terminates, at its top, in a supplemental deflector, 4, which is inclined or curved in opposite direction to the body of the wall, that is to say, towards the branch, 4.
It will be apparent to those skilled in the art to which the invention relates, that, by the provision and operative result of the members hereinbefore described, the separation of water from steam incoming to the middle cylinder, is materially facilitated by the diversion and reversal of direction of flow of the current of steam by the separation thereof from that going to the right hand cylinder by the provision of separate channels and interposed deflecting partition walls. It will also be seen that the construction disclosed is simple and inexpensive, and is readily ap plicable in connection with standard practice.
The invention claimed and desired to be secured by Letters Patent, is s 1. In a locomotive, having a middle cyl-. ind er and two side cylinders, each provided with a distribution valve chest, the combination, with a side cylinder distribution valve chest, of means for separating the currents of steam incoming thereto and to the middle cylinder chest and reversing the direction of branches.
3. In a locomotive, having a middle cylinder and two side cylinders, each provided with a distribution valve chest, the combination, with a side cylinder valve chest, 01"- a steam inlet, having a branch leading directly thereinto and a branch leading to the middle cylinder chest; a deflecting partition wall, interposed between said branches, and inclined downwardly and towards the direction or the flow of steam; and a deflecting partition wall, interposed between said branches and inclined upwardly and away from the direction of the flow of steam.
4;. In a locomotive, having a middle cylind-er and two side cylinders, each provided with adistribution valve chest, the COIDblI1ttion, with a side cylinder valve'chest, of a steam inlet, having a branch leading directly thereinto and a branch leading to the middle cylinder chest; a deflecting partition wall, interposed between said branches and inclined downwardly and towards the direction of the flow of steam; a deflecting partition wall, interposed between said branches and inclined upwardly and awayfrom the direction of the flow of steam; and a supplemental deflector, formed on the top of said last specified partition wall and inclined in reverse direction thereto.
HARRY S. BURNHAM.
