SPECIFICATION forming part of Letters Patent No. 670,060, dated March 19, 1901.

Application filed August 27, 1900. Serial No. 28,103. (No model.)

To @ZZ whom, it may concern,.-

Be it known that I, HIRAM M. QUICK, a citizen of the United States, residing at 214 Van Houten street, in the city of Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Gasolene-Motors, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to explosive-engines, and pertains more especially to gasolene-engines, though some of the mechanism and devices are adapted for use in other forms of explosive-engines. A

One object of my invention is to provide in an explosive-engine a rotary disk valve adapted to communicate with an inlet-port and an exhaust-port at certain intervals and -to engage an igniting device when required, so that in one revolution of the valve the charge will be admitted, exploded, and discharged, and the product of combustion passed off, making way for a new charge explosion and exhaust during thesucceeding revolution.

A further object is to diminish, if not obviate, the strain and vibration in an explosive-engine of two or more cylinders.

A further object is to provide a simple and effective means of controlling the admission of a charge, the exploding of the same, and the discharging of the products of combustion in an explosive-engine.

A further object is to so construct a gasolene-engine that it shall be comparatively simple in construction, easy to manipulate, comparatively noiseless, and which shall be eectual in all respects in the performance of its functions.

My improved disk valve and igniter constitute Vthe essential points in my gasolene-engine and may be utilized whether the engine has one or more cylinders.

With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure l is a longitudinal vertical section of an engine embodying my invention. Fig. 2

is a horizontal longitudinal sectional view of same. Fig. 3 isa side View. Fig. 4 is an end View. Fig. 5 is a cross-sectional view through the cylinder. Fig. 6 shows the relative position of the valve in revolving with the inletport and exhaust-port of the cylinder-head. In this ligure the inlet-port and the exhaustport are the same distance from the center, and one opening in the disk valve serves as a communicating means for both the exhaust and inlet ports of the cylinder-head. Fig. 7 is a view showing the cylinder-head having an inlet-port above the center and an exhaustport below, but nearer to, the center than the inlet-port and the position of the disk valve in revolving. ln this case the valve has two openings-one to communicate with the inlet-port and one to communicate with the exhaust-port. lf the engine be a two-cylinder engine, the second piston is set to work one-third of the turn of the cran k-shaft either earlier 0r later than the piston of the iirst cylinder. If there are three cylinders, they are worked crie-third of a turn of the crank-shaft apart.

The cylinder portion A and the crankchamber-B of the engine are secured together through the flanges a and b, and between the cylinder-wall and the outside casing are the spaces a.' or water-jackets for the circulation of water, a2 and 0,3 being the inlet and outlet for water. The engine stands onrthe legs 0.4 and b3, and the crank-shaft E is mounted in the bearings b'. The crank-chamber B is provided with a door b2 to permit the oiling of the crank-shaft and the adjustment of the connecting-rods F. Inside of the cylinderheads C are the water-spaces c, adapted to be connected with the water-jackets o by connections c o2. The connecting or piston rods F are mounted in the cranks c', e2, and e3 of the crank-shaft E. The connecting-rods F are provided with the caps j', having the hinge f. Said caps are not mounted at right angles to the rod. G is the piston; g, the center partthereof; g', the end of same; g2, the securing-bolts which hold the parts together, and g3 cylinder-rings. In Figs. l and 2 the cylinders and pistons are constructed as is usual.

The igniter H is held in position by the IOO i .Tt

2 evdoe spring h on the igniter-shaft. On the inner end of the igniter-shaft is a crank h, which is provided with any suitable sparking material. A wire h2 connects with battery and with igniter and valve.

I is my colnbination feed and exhaust valve and igniting contact, the disk valve having on its face a pin fi, which in the revolution of the valve comes in wiping contact with the sparker on the crank end ofthe igniter-shaft to explode the charge admitted through the inlet-ports in the cylinder-head and valve into the explosion-chamber. The val ve is held in its seatby a spring e" on the valve-shaft or by other suitable means. The inlet and exhaust ports in the cylinder-heads are indicated by the letters 2 and is. A pipe e connects outlet and the mufiler D. Shafts K connect the Valve-shafts andthe crank E. Bevelgears on the valve-shafts, shaft-s K and crank E meshing tofoperate the valves from the' crank. L is the ily-wheel on thecrank E.

As has been already intimated in the de` scription of Figs. 6 and 7, I use one or more openings in my rotary disk valve which are adapted to be the means of communication with the inlet and exhaust ports in cylinderhead. This I claim not to be a departure from the spirit of myinvention. When only one communicating opening is employed in the valve, then, as shown in Fig. 6, the inlet-port and the exhaust-port of the cylinder are located ninety degrees apart upon the periphery of a circle which is concentric with the periphery of the valve-shaft, or ninety degrees apart, but equidistant, from a common center. Thus the one opening in the rotary disk valve would register consecutively with the exhaust-port and the inletportin cylinder-head. When registering with the inlet-port, the cylinder would be charged at one stroke of the piston, at the next stroke the charge would be compressed and ignited, the explosion driving the piston back, another stroke discharging the products of the'explosion as the combined inlet and outlet opening of the valve (in Fig. 6 indicated by 725) registers with the exhaust-port 3 of the cylinder, as shown in part 2 of Fig. 6, and the next stroke of the piston would bring the valve-opening 115 in communication again with the inlet-port i2 for another charge, as shown in part 3 of Fig. 6.

The approximate position of the contactpin 1l on the disk valve is shown in Figs. 6 and 7. The dotted lines crossing each other at right angles divide the circle representing a revolution of the rotary disk valve into quarters, each quarter-revolution representing one stroke of the piston in Figs. 6 and '7. Throughout said figures, 722 and 3 represent the inlet-port and exhaust-port, respectively, of the cylinder-head. In Fig. 6 part l shows the cylinder-head with the inlet and exhaust ports equidistant from the center and the igniter.V Part 2 shows the Valve I and cylinder-head, the igniter device overlapping the valve, so as to come in contact with the pin t during the revolution of the valve, lthe valve-opening-t'5 registering with the exhaust-port is in cylinder-head. Part 3 shows the valve-opening@l5 registering with the inlet-port 112 of the cylinder-head. Part 4 shows both ports closed. The cylinder is compressing until, as part 5 shows, that the charge has been exploded, the pin '1l having passed the ignitiug device,and the next stroke of the piston will bring the valve to the position shown in part 2 of Fig. 6, with the valveopening 715 regis-tering. with the exhaust-port 3 of the cylinder-head. In-Fig. 7 part I shows the cylinder-head I and differs from part l iu Fig. 6 only in this, that the inlet and exhaust ports" i2 and' 3 are differently located, the' inlet-port 2 being above'the'c'enter and the exhaust-port i3 below and nearer to the center than the inlet-port. In this figure theV valve I is shown to have two openings to communicate with the inlet and exhaust ports, respectively. (See parts' 2, 3, 4, and 5 of Fig. 7.) In this modification the communicating openings are indicated, respectively, by 116 and i7. In part 2, Fig. 7, the exhaust is open, the opening 6 of the rotary disk valve registering with the' exhaustport i3 in the cylinder-head. In part 3 theiulet-port is open and the exhaustis closed, the valve-opening i7 registering with the inletport 912 in cylinder-head. In part 4 both the inlet and exhaust ports are closed, and at the next stroke of the piston the chargeis compressed andv red, both ports being closed, as shown in part 5, the contact-pin having engaged and passed the igniter h, when the explosion will drive the piston back and the valve will turn another quarter of a revolution, when the valve will be in theY position shown in part l, Fig. 7, the opening in the valve 6 registering with the exhaust-port 3 in the cylinder-head, the product of the explosion being discharged through the exhaust.

In the drawings one revolution ofthe crankshaft causes the valve to make half a turn', so that there will be four strokes of the pistontwo backward and two forward-each revolution of the rotary disk valve. Other arrangements may be made, however, without departingfr'om the scope of my invention.

By setting the several valves the time of the explosion in the several cylinders may be regulated, so that the vibration caused by one may be counteracted by the successive explosions or vibrations caused thereby. Hence I claim that in my invention I reduce the vibration, avoid the sound or clack of valves, muftl'e th'e sound of the exhaust, reduce the friction of the piston in the cylinder, and obtain high piston speed, and in my noiseless rotary disk valve I accomplish three important objects--tirst, control the admission of the charge; second ignite and explode it after its compression, and, lastly, provide for the discharge of the products of combustion through the exhaust. By the adjustment of the tem- IOO IIO

evope 3 perature of jacket of water I obtain an economical output of actual power.

With this description of myinvention, what I claim is- 1. In an explosiveengine, an explosivechamber having au inlet-port and an exhaustport, in combination with an oscillating igniter-shaft havinga crank extending into said explosion-chamber, a rotary disk valve controlling both said ports, a contact-pin suitably located on the disk valve and adapted to come in contact during the revolution of the valve with the crank end of the ignitershaft, and electrical connections between the ignitershaft and the valve shaft substantially'as set forth.

2. In an explosive-engine, an explosionchamber in combination with an oscillating igniter-shaft having a crank extending into the explosion chamber and a rotary disk valve provided with a contact-pin which is integral therewith adapted to engage the crank end or terminal of the igniter-shaft and electrical connections between valve and igniter.

3. In an explosive-engine, an explosivechamber having an inlet-port and an exhaustport, in combination with a rotary disk valve having two openings or ports adapted to communicate at certain intervals with said inlet and exhaust ports respectively, said openings or ports in the rotary disk valve being located, the one on an inner and the other on an outer one of two concentric circles, of which the center of the disk valve forms the common center, a contact-pin forming an integral part of said rotary disk valve and an oscillating electrode with which said contact-pin is adapted to come into frictional engagement during the revolution of the rotary disk valve with which it is electrically connected substantially as set forth.

4. In an explosive engine, the explosivechamber, in combination with an oscillating igniter-shaft extending into said explosion-,

chamber, the valve-shaft also extending into said chamber, and a rotary disk valve secured on said valve-shaft, and provided with a pin designed to engage, during the revolution of the disk, with the contact portion on the lower end of said oscillating igniter-shaft, substantially as set forth.

5. In an explosive engine, the explosivechamber in combination with an oscillating igniter-shaft extending into said explosionchamber, the valve-shaft also extending into said chamber, and a rotary disk Valve secured on said'valve-shaft, and provided with a pin designed to engage during the revolution of the disk with the contact portion on the lower end of said oscillating igniter-shaft,the crankshaft and connections between said crankshaft and said valve-shaft, substantially as set forth.
