LOCOMOTIVE CYLINDER SADDLE.

Application filed July 18,

The object of our invention is to make a cylinder saddle casting in two parts, one part being a duplicate of the other part, and each part having a cylinder, a valve chest, and an exhaust port therein, the casting having a supporting frame open for inspection of the inner walls of the structure.

In the accompanying drawings:

Fig. 1 is a front elevation of a cylinder saddle illustrating our invention;

Fig. 2 is a plan view;

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

Fig. 4 is a sectionalplan View on the line 4 Fig. 3.

This application is a companion to one filed by us on the 16th day of July, 1927, under Serial N 0. 206,180, in which the cylinder structure is made as a single casting;

The saddle 1, in the present instance, is made in two parts 22, each part having a flange 3, the parts being bolted or otherwise secured together as shown in Fig. 1.

In each ofthe parts 22 of the saddle is a cylinder 4-, a cylindrical valve chest 5, and an exhaust passage 6 tubular in form.

The steam supply passage 7 is in a portion of the structure projecting above the valve chest and is arranged to be coupled to an outside steam supply pipe and .communicate through passages 8-8 with the end of the cylinder 4.

The exhaust passage 6 is in the form of a Y, extending from each end of the valve chest to the nozzle 9.

The central portion of each section of the cylinder saddle is hollow, v the supporting frame 10 having openings 11 therein, so that the outer walls of the exhaust passage 6 can be inspected as well as other portions enclosed by the frame, and the'upper portion 16 has openings 17 back of the valve chest. By this construction, any defects in. the casting can be 1927. Serial No. 209,692.

readily detected and repaired by welding. The structure is preferably made of cast steel but it may be made of cast iron if desired.

At the upper portion of each part of the cylinder structure is a curved saddle 12, on which the boiler rests and to which it is secured.

W hen the parts of the cylinder structure are secured together, the ends of the two exhaust passages are close together, being separated by a narrow partition formed on the two parts of the structure.

The structure, when assembled, rests on the main frame 13 of the locomotive and the flanges let and 15 are secured to the frames by bolts or other fastenings.

When the parts are made of cast steel particularly, it is necessary that all parts of the casting be carefully inspected before leaving the shop.

By the above construction, every part of the structure can be examined and any defects can be readily repaired by welding.

We claim:

A cylinder saddle for locomotives made in two parts, each part being an integral structure, and one part beinga duplicate of the other part, each part having a steam chest and a cylinder, an exhaust port in the form of a Y leading from each end of the steam chest to the nozzle opening, a steam inlet passage, passages leading from both ends of the steam chests to the cylinders, a supporting frame extending on each side of the exhaust passage, the supporting frame having openings in both ends opposite the exhaust ports, the upper portion of the structure having openings located back of thevalve chests, so that access may be had to the outer walls of the Valve chests and the walls of the exhaust passages at the Y.
