EXPLOSWE-ENGINE.

To all whom it may concern:

Be it known that I, FRANK J. GREMEL, a citizen of the United States of America, residin at Detroit, in the county of Wayne and gtate of Michigan, have invented certain new and useful Improvements in plosive-Engines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to explosive engines, and more particularly to an arrangement of the parts thereof which greatly simplifies the construction and reduces the weight per horsepower.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a view partly in front elevation and partly in section, of an engine that embodies the invention; Fig. 2 is a view, partly in elevation and partly in section, of the crank case side of a cylinder; and Fig. 3 is a view in elevation of the valve side of the engine.

Referring to the drawings a pair of cylinders 1 are each closed at the lower end, and are each formed in one piece with laterally extending base and crank case walls 2, which when united along their margins 3 by bolts 4 or the like, hold the cylinders in parallel relation and form a complete housing. A cap or head 5 is removably secured on the open end of each cylinder. A cylindrical piston 6 with packing rings 7 or the like near each extremity, is provided for each cylinder. Wrist pins 8 extend radially from the center of each piston, through guide slots in the cylinder wall into the housing, and their outer ends are pivoted or other wise secured to guide blocks 9 which travel in guide ways 10 formed in webs 11 spanning the outer, upper part of each half casing or housing. Each wrist pin is coupled by a connecting rod 12 to an adjacent crank pin 13 of a main shaft 14. The latter is journaled in a bushing 15 inserted in the cylinder extensions.

A valve cam-shaft 16 is journaled on the cylinders, the casing walls being interrupted and extending outwardly to receive a cover plate 17. At each end of the cylinders properly disposed valve seats, one of which is indicated at 18, have closures 19 on tappet stems 20 with closing springs 21 thereon, a single cam 22 for each cylinder reciprocat- Specification of Letters Patent.

ing the adjacent tappets alternately at each end thereof.

A single cover plate 23 is secured against the outer 'margins of the casing walls 2. An intake opening 24: in the outer face of this plate in which a carburetor or other source of fuel supply may be secured, is connected by ducts 25 in the plate with the intake of the several cylinders. A manifold pipe 26 likewise integrally formed on the cover plate has intakes 27 severally registering with the exhaust ports of the cylinders. If the cylinders are water-jacketed, as herein indicated, a water supply pipe 28 is formed integrally on.or secured to the cover plate with openings indicated at 29 into the cylinder jackets.

All the moving parts, including the cam shaft, cams, and tappets, are thoroughly lubricated by oil splashed up by the cranks, the base forming a reservoir which may be drained by removal of a suitable screw-plug 30 or the like. As the cover plate is close to the cylinders, a carburetor mounted thereon and connected to the intakes, is kept warm by the cylinders, thereby increasing its efiiciency. As the cranks turn between the lower ends of the cylinders, it reduces the height of the motor and makes it very compact.

A very simple, easily assembled motor is thus obtained which completely houses the cranks without a separate or attached crankcase.

Obviously, the details of construction may be varied without departing from the spirit of the invention and I do not care to limit myself to any particular form or arrangement of parts.

What I claim is:

1. In a mot-or, cylinders closed at each end and provided at each end with intake and exhaust ports, a wall on one cylinder detachably-secured at its margin to a mating wall on the companion cylinder, forming therewith a base and crank shaft housing, a piston in each cylinder, a wrist pin extending from each piston through alongitudinal slot in the cylinder and sliding in guide-ways on the wall, and a crank shaft journaled in the walls and coupled operatively to each wrist pin.

2. In a motor, cylinders closed at each end and provided at each end with intake and exhaust ports, a wall on one cylinder a crank shaft journaled in the walls, and a connecting rod coupling each wrist pin with the crank shaft, the walls forming a housing and crank shaft base.

3. In a motor, cylinders closed at each end and provided at each end with intake and exhaust port-s, a wall on one cylinder detachably-secured at its margin to a mating wall on the companion cylinder, forming therewith a base and crank shaft housing, a piston in each cylinder, a wrist pin extending from each piston through a longi tudinal slot in the cylinder and sliding in guide-ways on the wall, a crank shaft journaled in the walls and coupled operatively to each wrist pin, and a cover plate detachably secured over an opening formed in the mating walls and provided with an inlet manifold opening into the several intake ports, and an exhaust manifold connecting the several exhaust ports.

4. In a motor, cylinders closed at each end and provided at each end with intake and exhaust ports, and with water jacketed walls, a wall on one cylinder detachablysecured at its margin to a mating wall on the companion cylinder, forming therewith a base and crank shaft housing a piston in each cylinder, a wrist pin extending from each piston through a longitudinal slot in the cylinder and sliding in guide-ways on the wall, a crank-shaft journaled in the walls and coupled operatively to each wrist pin, and a cover plate detachably-secured over an opening formed in the mating walls and provided with an inlet manifold opening into the several intake ports, and an exhaust manifold connecting the several eX- haust ports and with a water pipe discharging into the water jacket.

5. In a motor, cylinders closed at each end and provided at each end with intakeand exhaust ports, a wall on one cylinder detachably-secured at its margin to a mating wall on a companion cylinder, extending below the cylinder ends and forming with the mating wall a base and crank shaft housing, a'piston in each cylinder, a wrist pin extending-from each piston through a longitudinal slot in the cylinder and sliding in guide-ways on the wall, a crank shaft j ournaled in the housing adjacent the lower end of the cylinder with its cranks playing between the lower ends of the cylinder, and connecting rods each coupling a wrist pin with an adjacent crank.

In testimony whereof I affix my signa-' ture in presence of two witnesses.
