THREE-CYLINDER COMPOUND LOCOMOTIVE.
Application filed July 14, 1927. Serial No. 205,645.
The object of our invention is to so construct a three-cylinder compound locomotive that poppet valves can be used to control the admission of steam to the cylinders and to control the exhaust therefrom.
In the accompanying drawings:
Fig. 1 is a front view of a three-cylinder saddle illustrating our invention;
Fig. 2 is a plan view;
Fig. 3 is a sectional elevation 011 the line 3-3, Fig. 2; y
Fig. 4 is a sectional elevation on the line 44, Fig. 2, showing the poppet valve in place;
Fig. 5 is a sectional plan view on the line 5-5, Fig. 1;
Fig. 6 is a sectional plan view on the line 6-6, Fig. 1;
Fig. 7 is a view similar to a portion of Fig. 4, with the valve omitted; and
Fig. 8 is a section on the line 8-8, Fig. 1.
The cylinder saddle 1, in the present instance, is made as a single casting, and has a central high pressure cylinder 2 and side low pressure cylinders 33. The latter cylinders overhang the side frames 4 of the locomotive as shown in Fig. 1.
The cylinder saddle is secured by bolts or other means to the main frame of the locomotive.
The boiler rests on the curved saddle section 5, at the centre of which is the exhaust nozzle 6. The high pressure steam inlet passage 7 extends from end to end of the cylinder structure. One end of the passage is coupled to a steam supply pipe leading from the boiler of the locomotive, while the opposite end is closed by a suitable cap@ The passage 7 communicates at each end with a passage 8, through a port 9, in which is a poppet valve 10 of any suitable type.
he passages 8 lead to the ends of the central high pressure cylinder 2, as shown in F ig. 6.
Communicating also with the passages 8 are exhaust passages 11, Fig. 5, through ports 12, in which are poppet valves 13.
The passages 11 extend to the valve chain-J her at one side of the cylinder structure as indicated by ll. and connect through ports 14 with a steam inlet passage 15 for the low pressure cylinder 3. v
In each port 14 is a poppet valve 25, which controls the flow of steam from the high pressure cylinder 2 t0 the low pressure cylinder 3.
In the ports 22 are poppet valves 24. The poppet valves 24 are actuated in proper time by any suitable mechanism (not shown), as the means for operating the valve is no part of our present invention.
It will be seen by the above description that the poppet valves for the high pressure cylinder are all 011 one side of the locomotive, and that the path of steam from the steam inlet passage 7 to the cylinder 2 is very short, so that by using poppet valves the steam admission and exhaust can be rapid and in considerable volume. The high pressure exhaust passa e is quite large and forms an expansion 0 amber for the steam as it passes from the high pressure cylinder2 to the low pressure cylinders 3-3, the valves of which are comparatively close to their respective cylin ders.
We claim:
1. The combination in a three-cylinder compound locomotive, of a cylinder structure having therein a central high pressure cylinder and side low pressure cylinders; a steam supply passage; inlet and exhaust passages at one side of the central cylinder and communicating with said central cylinder and with the steam passage; poppet valves for controlling the flow of steam to and from the said central cylinder; an exhaust passage for the central cylinder extending to each side of the cylinder structure; passages communicating with both ends of the low trolling the flow of steam to and from the low pressure cylinders.
2. The combination in a three-cylinder structure for locomotives, in which the central cylinder is a high pressure cylinder and the low pressure cylinders are located in extensions beyond. the frames of the locomotive; a steam supply passage arranged to be coupled to asteam pipe leading from the boiler; two sets of poppet valves at one side of the central cylinder; passages leading from the steam supply passage to the ends of the said central cylinder; an exhaust passage leading from the central cylinder to the low pressure cylinders, said poppet valves controlling the flow of steam to and from the central cylinder; ports and passages leading to and from the side low pressure cylinders; and valves controlling the steam flowing to and from the cylinders.
3. The combination in a compound cylinder structure for locomotives hating three cylinders therein, the central cylinder being the high pressure cylinder and the side cylinders being the low pressure cylinders; a through steam supply passage in said structure arranged to communicate with the steam pipe leading from the boiler passages communicating with the ends of the central cylinder; an exhaust passage also communicating with the said passages through ports; two sets of poppet valves controlling the flow of steam to and from the said central cylinder, the exhaust passage for the central cylinder extending under the central cylinder and under the Steam supply passage and of such size as to form a mixing chamber; passages communicating with the end cylinders and connected through ports with the high pressure cylinder exhaust; exhaust passages connected to the said cylinder passages and extending to the nozzle of the structure; and two pairs of poppet valves at each side of the cylinder structure controlling the flow of steam to and, from the said side cylinders.
