COMBUSTION-MOTOR.

SPECIFICATION forming part of Letters Patent No. 750,336, dated January 26, 1904.

Application filed June 19 1903.

To aZZ whom it may concern:

Be-it known that I, J A0013 F. BENTZ, a citizen of the United States, residing at Schenectady, county of Schenectady, and State of New York, have invented certain new and useful Improve:

ments in Combustion-Motors,of which the fol-' lowing is a specification.

The lnventlon relates to such improvements; and 1t consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings and the reference characters marked thereon, which form a part of this specification.

Similar characters refer to similar parts in the several figures.

Figure 1 of the drawings is a view in end elevation of the improved combustion-motor. Fig. 2 is a vertical section. taken on the broken line 2 2m Fig. 1. Fig. 3 is a similar section showing a movement of the disk and piston. Fig. 4 is a horizontal central section taken on the broken line 4L 4: in Figs. 1' and 2. Fig. 5 is a sectional view similar to that shown in Fig. 3, showing a modified form of construction. Fig. 6 is a similar section showing a movement of the disk and piston. Fig. 7 is central horizontal section of the countersunk wall of the piston-chamber case detached. Fig. 8 is a similar section of the case, wall, and disk, taken on the broken line 8 8 in Fig. 6.

Fig. 9 is a plan view of the disk and pin and' the crank-disk 12 and crank-shaft 13. (Shown detached in Fig. 9 and inserted in the countersunk wall in Fig. 8.)

The piston 15 is composedof a rectangular Serial No. 162,211. (No model.)

frame which is adapted to reciprocate in the piston-chamber 7, forming practically a gastight connection with the end walls 3 and 4 and two opposite sides ofthe frame 2, also with the inner face 16 of the disk, which is flush with the inner surface of the wall 4:, as shown. The inner surface 17 of the sides of the piston form a slideway for the bearingblocks 18 inclosing the crank-pin 20.

The foregoing description does not differ from that of similar parts contained in my improved fluid-motor for which I have filed an application for a patent concurrently here- Wit 1.

In my improved comb ustion-motor that part of the piston-chamber located on one side of the piston into which the ingredients of the explosive mixture are introduced may be termed the mixing-compartment and that upon the opposite side of the piston in which the igniting mechanism acts upon the mixture the combustion-compartment.

The mixing-compartment 21 is provided with an induction-port, which may be through a supply-tube 22, leading from a source of supply. (Not shown.) As shown in the first four figures of the drawings, the supply-tube is screw-threaded and inserted in a similarthreaded aperture in the frame 2. Its portaperture is controlled by the check-valve 23, secured to the frame by screw 24.

The combustion-chamber 25 may be provided with any known means for igniting an explosive mixture, as the electrodes 26, separated a short distance from each other and connected, respectively, with the ends of an induction-coil and the contact 27, adapted to be electrically connected by a metallic plug 28 and form an electric circuit containing a battery and primary coil (not shown) in the usual Well-known manner. The mixing and combustion con1- partments are adapted'to be connected at certain times by the by-pass port 30, contained in the frame 2 and leading around the piston. The combustion compartment is provided with an eduction-port for exhausting the same, which may be tube 31, leading from such compartment to the atmosphere.

When the parts are in the position shown in Fig. 2, the electric circuit is completed by contact of plug 28 with the contact 27, and an electric spark passes from one of the electrodes 26 to the other, and if the combustion' chamber has been charged with an explosive material an explosion occurs, which acts upon the piston and causes it and the crank-pin to move from the position shown in Fig. 2 to that shown in Fig. 3, provided, of course, that the parts had sufiicient momentum or other application of force to carry the crank-pin beyond the dead-center line. The mixingcompartment having been filled with an explosivegas mixture through the inductionport and closed by the check-valve, the mixture will be compressed continually by the movement of the piston until the piston opens the by-pass port to the combustion-compartment, after which the compressed gas will expand and rush into the combustion-compartment, the products of combustion therein exhausting through the eduction-port, which has been opened by the piston before the by-pass port was opened. As the momentum of the parts, which may be assisted by a fly-wheel, (not shown,) carries the piston and pin from the position shown in Fig. 3 to that shown in Fig. 2 the eduction and by-pass ports are closed by the piston and a new supply of explosive material drawn into the mixing-compartment, the check-valve readily yielding for that purpose, and the operation will be re.

peated and continued as long as the supply of explosive material continues.

When desired, a disk-controlled inductionport may be substituted for the port controlled by the check-valve by inserting the supplypipe L0 in the countersunk wall, as seen in Fig. 8, and providing a port-aperture 41, leading therefrom into the countersink, and providing the outer side of the disk with a segmental annular groove 4c2, adapted to register a part of the time during each rotation of the disk with the port-aperture 4:1 and with a segmental annular plane surface 43, extending from one end of the groove to the other end and adapted to close such aperture between the intervals of registering with the groove. The disk is also provided with one or more port-holes 44, leading from such groove into the piston-chamber. The plane surface serves to close the induction-port during the action of the explosive force upon the piston, and by arranging the port-holes near the forward end of the groove as shown in Fig. 5 there can be no communication through the groove from one side of the piston to the opposite side, yet the induction-port will remain open to the mixing-compartment practically all the time such compartment is being increased in size by the movement of the piston toward the combustion-compartment. The

eduction-port may also be controlled by the rotary disk when desired. This may be accomplished by providing the disk and shaft with an exhaust-passage 50, leading to the atmosphere at the time of exhaust through a lateral slot 51 in the shaft and a port-hole 52 in the bearing 53. The relative position of the parts is shown partly by dotted lines in Fig. 5. At the proper time for exhausting the combustion-compartment the two slots 51 and 52 register with each other, and at all other times the slot 51 is closed. The exhaust preferably commences just before the by pass-port is opened to the combustion-compartment.
