TWO-CYLINDER STRUCTURE FOR LOCOMOTIVES.

Application filed July 16 The object of our invention is to make a locomotive cylinder structure, having two high pressure cylinders, as a single casting, and to so design the structure that the outer walls of the passages can be inspected from the outer side.

In the accompanying drawings:

Fig. 1 is a front elevation of a locomotive cylinder structure illustrating our invention Fig. 2 is a sectional plan view on the line 22, Fig. 1;

Fig. 3 is a transverse sectional view on the line 3-3, Fig. 2;

Fig. 4 is a sectional view on the line 4-4, Fig. 3; and

Fig. 5 is a-sectional view on the line 5-5, Fig. 3.

11 are the side frames of a locomotive upon which the cylinder structure 2 is mounted. The cylinder structure 2 is made as a single casting, having flanges 3 which are bolted to the frames 11.

The cylinder structure extends beyond the frames at each side, and in the extensions are the cylinders L-A and cylindrical valve chests 55.

The saddle 6 is located at the centre of the structure and is curved to conform to the boiler to which it is attached.

The steam inlet ports 7-7 communicate with the valve chests 5-5, as shown, and with steam supply pipes leading from the boiler.

Passages 88 connect the cylinders 4l4 with their valve chests 5-5, as shown in Fig. 4. In each valve chest are two bushings 9 9, and the cylinders are preferably bushed as shown.

In the present instance the steam chambers of the valve chests are at the centre and the exhaust passages are at the ends of the valve chests (see Fig. 4)

In all the and valve chests have been omitted.

figures the heads for the cylinders I 1927. Serial N0. 206,180.

The exhaust passages 10-40, which lead from the passages at the ends of the valve chests, are gradually tapered from the valve chests and curved upwards at each side of a central partition 11, terntiinating at the exhaust nozzle 12.

The outer walls of the exhaust passages are exposed and can be examined through openings 13 in the end walls 14 of the cylinder structure, so that if leaks are discovered the openings can be readily closed by welding.

In a central web 16 are additional inspection openings 15, that access can be had to the portion. of the casting between the cylinders and the parts of the exhaust passages exposed through the openings 13.

By the above construction, all the walls of the structure within the cylinder structure are exposed for examination and for repairs if necessary, and as all of the outer surfaces of the walls are exposed, every part of the structure can be readily examined, and any defects detected can be readily remedied.

The structure is preferably a unitary steel casting, although it will be understood that in some instances it may be of cast iron or other metals without departing from the main feature of the invention.

We claim:

An integral cylinder saddle having a cen tral web, cylinders and valve chests formed in the saddle, and having exhaust passages leading from the cylinders to an exhaust nozzle, said exhaust passages being in the form of a tubular casting; and a supporting frame enclosing said tubular casting, Laid frame having openings through which access may be had to all parts of the outside walls of said tubular casting and having openings in the central web thereof.
