JOHN ANDREW KREMER, OE AURORA, ILLINOIS.

INTERNAL-COMBUSTION ENG-INE.

Be it known -that 1,' JOHN ANDREW KREMER, a citizen of the United States, re-

siding at Aurora, in the county of Kane and State of Illinois, have invented a'new and useful Internal-Combustion Engine; and I do hereby declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the arf to which it appertains to make and use'the same.

ternal combustion engine.,

As an object of the invention it is the aim to provide a single piston valve internal combustion motor, which can be .installed and constructed in such wise as' to reduce the time, labor and material to a minimum.

Another object of the invention is to improve and simplify the construction of such motor, and-to provide ball bearing mountings for the crank shaft and crank connection, and the eccentric shaft, `so as to lessen the friction of said parts.

One of the features of the invention is'to so construct and connect the cylinder to the frame of the engine, as to permit the parts to be easily and quickly assembled or disassembled with a. minimum amount of labor and time.

Another object of the invention is to provide improved means of connecting between the piston and the pitman rod of the crank, so as to relieve the crank and the pitma-n rod of the sudden jar or impact incident to .the explosion of the charge.

In practical fields the details of construction may necessitate. alterations, falling within the scope of what is claimed. l

The invention comprises further features and combination of parts, as hereinafter set I forth, shown in the drawings and claimed.

In the`drawings:-Figure 1 is a View 1nside elevation showing the motor constructed on a horizontal plane. Fig. 2 is a longitudis nal sectional View; Fig. 3 is a cross sectional view through the frame, showing how the frame is. connected to the base. Fig. 4 is a horizontal sectional view through the connection between the piston and the pitman rod. Fig. 5 is a sectional view showing the 'engine constructed as a vertical motor.

Referring to the drawings, more particularly to Figs. 1 and 2, the numeral '-1 designates thebase, the forward ortion of which is provided with s. dove-tailed recess2 for Specification of Letters Patent.

This invention relates to an improved inthe reception of a dove-tailed part 3 of the forward supportingv standard 4, which supports the forward end of the cylinder 5.

The rear portion of the base l is provided.y with elongated dove-tailed grooves or recesses 6 for the reception of the lower part 7.of the sides 8 ,of the frame of the motor. The end portion 9 of the cylinder 5 is constructed with arlange 10, through which Patented Feb. 22, 1916. Application led January 2, 1915. Serial No. 140.

ily assembled and disassembled, aswell as easily and quickly permitting the other parts of the motor to be disassembled or assembled.

Mounted in ball bearings 14 of the sides of the frame is a crank shaft 15 provided with a crank' 17 and a sprocket 18 at one end, which is keyed at 19 to said shaft. Also mounted in ball bearings 20 of the sides ofsaid frame is a shaft 21 having an eccentric 22 and a spur gear 23. A sprocket chain- 2 4 passes about the sprocket 23v and the sprocket 1S as shown. The cylinder 5l is provided with a combustion chamber 26, there being inlet and exhaust from the combustion chamber to the piston valve chamlber 27, said inlet and exhaust ports being designated by the numerals 28 and 29. The head' 30 of the cylinder has the usual sparking plug 31. The mixture enters the piston valve chamber from any suitable source (not shown), through the intake port 32, while' the utilized' gases pass from the cylinder 27 to the atmosphere through the exhaust vport piston valve casing 27` Mounted in the is a piston 34, the rod 35 of which passes through the p'acking box 36 and is connected at 37 to the pitman rod 38, which is pro- `vided with an eccentric strap 39,'engaging about the eccentric 22.

The piston 41 in the cylinder 5 is' of the usual hollow construction, and provided with the usual piston rings 42,. Theopposite'sides of the interior of the hollow7 piston 41 'are provided with guides 43 to receive the member 44,- there being upon the opposite sides of each member stout coil springs 45, which engage the end of each guide,- thereby yieldably mounting said members. Journaled in the members is a pivot pin 46, on which sleeves 47 are mountwhieh hold the Pitman rod 48 substantially centered upon the pivot pin. The pitman rod 48 is in turn connected to the crank of the crank shaft, by means of ball bearing connections. as shown at 50, the cap plate 5l acting to hold the parts in their proper places. It will be observed that as the charge is ignited, the yieldable connections between the pitman 4S and the piston of the cylinder 5 will relieve the sudden jar or impact be tween the pitnran and the crank shaft.

Referringr lo Fig. 2 4it is to be understood that a charge has been tired. the piston -tl having been fori-ed to the position shown in full lines,-the piston ZH having been moved as shown also in 'full line 'l`he momentlnn carries .the piston -ll forwardly, thereby fort-iin.l the remaining` utilized gases through the exhaust; 2S), the piston 3J: having been moved to the dotted line position y. Then when the pieton -ll travels back again, the port is uncover-ech and a chairgre is drawn from behind the piston 34 into the combustion chamber, thel piston 3l* having;r been moved to the dotted line position S. rl`he piston l1 then travels forward again and compresses the charge7 and at the saine time Mhb piston Je moves back to the dotted line l position y, elosinr the port Q8. Immediately following;l the compression of the charge the charge is ignited, forcing the pieton 4l backwardly, and in so doing-the port Q9 is uny covered, by the piston 34: niovingto the tall' line position, thereby allowing the utilized gases to escape. 'lfheee cycles; ol operations are consecutively repeated. ae the engine con- 35 tinuousl)Y operates.
