OSCILLATING ENGINE.

SPECIFICATION forming part of Letters Patent No. 479,012, dated July 19, 1892.

Application filed December 11, 1891. Serial No. 414,671. (No model.)

To aZlwhom it may concern:

Be it known that I, JULIAN Moss, of Detroit, in the county of Wayne and State of Michigan,have invented certain-new and useful Improvements in Oscillating Engines, of which the following is a full, clear, and exact description.

This improvement relates to that class of oscillating engines in which there are two pistons with a Valve set between them; and the invention consists in the peculiar construction, arrangement, and combinations of parts hereinafter more particularly described and then definitely claimed.

Figure 1 represents a side View of an engine constructed according to my improvement; Fig. 2, a front View of the same; Fig. 3,21. central vertical transverse section of the cylinder and its immediate connecting parts. Fig.4 is a similar view of parts of the same, taken at right angles to that shown in Fig. 3.' Fig. 5 is a section through the valve and part of the cylinder, showing it giving steam to the top section of the cylinder and exhausting from the bottom. Fig. 6 is a similar section showing the steam passing into the bottom section and exhausting from the top. Fig. 7 is a similar section with the valve arranged to reverse the engine. Fig. 8 is a side 'view with the cylinder in section. v

Referring now to the details of the drawings by letters and figures, A represents the standards of the engine, having bearings B, in which runs the main shaft 0, carrying a face-plate D and wrist-pin or crank d, to which is connected the piston-rod E, carrying pistons e e and passing through the stuffing-boxes g g on the valve-box G and through an aperture h in the valve H.

The valve-box is provided with trunnions I I, mounted in suitable bearings B at the upper part of the standards, and carries the sections jj of the cylinder J, which sections are boltedthereon, but of course may be cast with the valve-box, if preferred.

For convenience in inserting the valve I usually cast one of the trunnions separately from the valve-box and bolt or screw these parts together after the valve is inserted. To

allow of this being done, such trunnion is provided with a flange i, as shown in Fig. 2.

The valve is preferably of conical form and is provided at its center with a division h, in which is formed the aperture h for the pur pose before explained, and in order that the valve may be shifted for the purpose of reversing the engine the aperture is enlarged at top and bottom, as shown in Fig. 8 and in dotted lines in Fig 4. At each end of the valve is a hollow pipe (indicated by K K) forming the steam and exhaust passages and passing through the trunnions I I and into glands L L, which form, with the hollow trunnions I I, stuffing-boxes to keep the ends of the trunnions steam-tight. The tops of these glands are provided with bosses Z Z, into which the steam and exhaust pipes MM are screwed, and below are petcocks NN to discharge the water of condensation. These glands are secured by studs 0 and nuts 0, so as to tighten the packing in the stuffing-boxes should the steam escape at these points. The pipe at the exhaust end of thevalve runs through the gland and through a cap Q (which, with the gland L, also forms a stuffing-box) and has its outer end closed and provided with a square stud R to receive the reversing-lever P, which is held thereon by a screw S or by any other convenient means. The lower end of this leler is broadened and slotted, as shownin Fig. 1, to receive a screw-stud T, by means of which and the nut t the lever may be held in any desired position.

Instead of setting the petcock E into the bottom of the gland I connect it by means of a T U and nipple u, so as to allow of the setting of the stud I into the T, as shown in Fig. 2.

The inlet side of the valve is provided with

ports

1, 2, and 3, and the exhaust has ports 4, 5, and 6, which are so arranged as to register with

ports

7, 8, 9, and 10, as desired.

The operation of an oscillating engine is so well understood that it seems almost unnecessary to describe this, and it will therefore be sufficient to say that in the position shown in Fig. 5 steam is entering the top section of the cylinder and pushing up the piston, while the exhaust is passing out of the lower section of the cylinder. As the crank passes around the position of the cylinder is changed to that shown in Fig. 6, when steam enters the lower section and the top section is exhausting. If it is desired to reverse the rotation of the shaft, the lever is changed to the position shown in Fig. 7, when the valve Will assume the position shown in said Fig. 7, and the shaft of the engine will then run in theopposite direction.

From the above description it will be seen that I have produced a reversing engine that is very simple, is cheaply built, not likely to get out of order, of great power in proportion to its size, and runs with but little friction.

What I claim as new is- 1. An oscillating engine having two pistons,

JULIAN MOSS.
