Specification of Letters Patent.

Patented Feb. 13, 1.917.

Application filed May 12. 1916. Serial No. 97,141.

To all whom it may concern:

Be it known that I, HARRY J. RIMBAGH, a citizen of the United States, residing at Hammond, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Explosive-Engines; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in engines (sf the internal combustion type, and more particularly to the construction of the valves. The invention has for its object to provide a novel type of rotary valve for explosive engines embodying a novel feature of construction, whereby the leakage of fuel or the exhaust products of combustion past the valve is efiectively prevented.

With this and other objects in view, the

invention consists in the novel construction, combination and arrangement of parts as will be hereinafter specifically described,

claimed and illustrated in the accompanying drawing, in which:

Figure 1 represents a plan view of the engine, the top part of the valve casing being removed and showing the valve partly in section,

Fig. 2 represents an end elevation of the engine,

Fig. 3 represents a vertical sectional view therethrough,

Fig. 4; represents ancnlarged detail sectional view showing the packing ring in position against the valve,

Fig. 5 represents a detail perspective view engine, illustrating one of the packing members in detail,

Fig. 6 represents a perspective view of the packing ring detached. T

Referring to the drawings in detail, wherein similar reference numerals designate corresponding parts throughoutthe 'several views, the numeral 5 indicates the cylinders of the engine, which are prefer-= ably of the waterjacketed type and receive the reciprocable pistons 6. The head of each cylinder is formed with exhaust and inlet ports 8 and 9, respectively, and the portions of the heads 7 overlying the ports 8 and 9 are cut away to present substanof the head of one of the cylinders of the tially semicircular recesses 10 and 11 in which are partially received the hollow cylindrical valves 12 and 13. The upper portions of the valves 12 and 13 are inclosed in a housing l-fl, having apertures therein receiving bolts 15, whereby the housing is rigidly secured to the cylinder heads 7.

The inlet and exhaust valves 13 and 12 are formed with inlet and exhaust ports 17 and 16,,which are adapted to be intermittently moved into registration with the inlet and exhaust ports 9 and 8 in the cylinder heads during rotation of the valves. One end of the valves is reduced, as indicated at 18, and are rigidly connected with gear wheels 19, one of which is connected by a train of gears 20 with a pinion 21 on the crank shaft22 of the engine, whereby the valves are mechanically operated during the operation of the engine.

Each of the inlet and exhaust ports of the cylinder heads 7 is surrounded by a groove 23, which is preferably rectangular in shape and receives a correspondingly shaped pack ing rin 24, which is suitably curved to snugly t against the convex surface of the valve and is resiliently retained in engagement therewith by a plurality of springs 25 fitted in recesses in the bottom wall of the groove 23 and arranged underneath the corner of the ring.

WVhat I claim is:

1. An explosive engine includinga cylinder having a head anda substantially semicircular depression formed in said head said head having a substantially rectangular port ltornied 111 the wall of said depression. and a" groove surrounding said port, a valve roitatably mounted 1n sald depression havmg 'a port therein adapted to be moved into registration with the first port, a substantially rectangular integral packing strip snugly received in said groove and engaging said valve, coil' springs engaging the corners of said packing strip to retain said packing strip in engagement with the 'valve, and means to prevent the displacement of said springs.

2. An explosive engine including a cylinder having a head and a substantially semicircular depression formed in said head, said head having a substantially rectangular port formed in the wall, of said depression, and a groove surrounding said port, a valve rotatably mounted in said depression having a port therein adapted to be moved into regwhereby said springs are prevented from he- 10 istration With the first port, a substantially ing displaced. v rectangular integral packing ring snugly In testimony whereof I aflix my signature IeCgiVQdl insaid grpove and engaged With in presence of two Witnesses.

sai va ve, and coi springs engaging the corners of said packing ring to retain said HARRY RIMBACH' packing ring in engagement with the'valve, -Witnesses:

the bottom Wall of the groove having a se A. T. STIGER,

ries of recesses to snugly receive said springs, F RED G. RIMBACH.
