Patent Number	Date	Title	Name	City	Description
593,034	Nov. 02, 1897	Gas Engine	Fred W. Spacke	Indianapolis, Marion County, IN	Abstract: The objects of my invention are, first, to produce a double-acting gas-engine; second, to provide means for heating the air before it is mixed with the gas; third, to provide improved means for exploding the gas, and, fourth, to provide improved means for removing the exhaust from both ends of the cylinder. Claim: In a gas-engine, a piston so shaped as to form an air-chamber between a portion of said piston and the walls of the cylinder, the said air-chamber having no direct communication with the combustion-chamber of the cylinder, an air-inlet leading into said chamber from the exterior of the cylinder, an air-outlet leading from said chamber, and intermediate valved connections between said air-outlet and the combustion-chamber of the cylinder.
667,595	Feb. 05, 1901	Automatic Stop for Governors	Fred W. Spacke	Indianapolis, Marion County, IN	Abstract: The object of my invention is to produce a simple but efficient means for automatically closing the valve in case of breakage of the driving-belt. Claim: In an automatic stop for governors, the combination with the valve-controlling spring and gear secured thereto, of a pivotal support for said worm whereby the axis of the worm will lie between said pivot and the axis of the gear, a cam adapted to engage said support, and means supported by the driving-belt for operating said cam so as to swing said pivotal support to withdraw the worm from engagement with the gear.
1,099,520	Jun. 09, 1914	Change-Speed Gearing	Fred W. Spacke	Indianapolis, Marion County, IN	Abstract: It is the object of our invention to provide a combination clutch and variable speed gearing wherein the clutch and the gears are controlled in common. Our improved clutch and, gearing is particularly designed for use between the motor and driving wheel of a motor cycle or light parcel delivery vehicle. Claim: In combination, a shaft, two wheels rotatably mounted on said shaft, a speed-reducing gearing, means for connecting one of said wheels to said shaft, means for connecting the other of said wheels to said shaft either directly or through said speed reducing gearing, and a common operating means for said two connecting means.

1,102,700	Jul. 07, 1914	Internal-Combustion Engine	Fred W. Spacke	Indianapolis, Marion County, IN	Abstract: Our invention relates to internal combustion engines, especially for motorcycles, and has for its object the provision of a multi-cylinder engine which combines a maximum of strength with a minimum of weight and space and operates with a minimum of friction. Claim: In an internal combustion engine, the combination of inlet and exhaust valves, a cam shaft for operating said valves, said cam shaft having a separate cam for each valve, the cams having cam faces on the sides, said lcam faces facing part toward one end of the axis of the cam shaft and part toward the other end thereof.

1,102,675	Jul. 07, 1914	Internal-Combustion Engine	John D. Lowe	Indianapolis, Marion County, IN	Abstract: In the operation of explosion engines, especially motorcycle engines, great difficulty is frequently experienced by reason of the dust and grit which settle on the exposed parts of the valve-operating mechanism, and especially on the valve sterns and associated parts at the top of the engine cylinder, this dust and grit making it impossible to produce proper and lasting lubrication so that sticking of the parts is frequent. Claim: In an internal combustion engine, the combination of a valve chamber, an inlet valve opening thereinto and provided with a stem, a cap-piece provided with a fuel supply passage and with a lubricant chamber into which the valve stein projects, means located in said lubricant chamber for transmitting motion to said valve stem, and a removable cover for said lubricant chamber.
1,108,265	Aug. 25, 1914	Internal Combustion Engine	Fred W. Spacke	Indianapolis, Marion County, IN	This application is a division of our copending application, filed September 8, 1911. The division filed December 11, 1912. Abstract: It is the object of our invention to simplify and cheapen, and at the same time to avoid certain disadvantages common in the construction of internal combustion motors, especially motorcycle motors. Claim: In an internal combustion engine,, the combination with a cylinder, piston, crank shaft, engine valves, and magneto, of a crankcase, a cap for said crankcase having an integral shaft chamber, a shaft mounted in said shaft chamber and driving said magneto and operating said valves, and gearing between said last named shaft and the crank shaft.

1,108,266	Aug. 25, 1914	Inlet-Valve for Internal-Combustion Engines	William Spacke	Indianapolis, Marion County, IN	Abstract: The object of my invention is to produce an effective means for supporting the inlet valve casing of an internal combustion engine in such manner that the inlet valve may be readily accessible. Claim: The cominiiation -with an engine and a valve there for, of a clamping ring for said valve provided with an inwardly projected flange, a casing member arranged to cover th valve, a 11(1a casing clamp comprising a hook-shaped meniber projected through the casing member and engaging the inwardly projected flange of the clamping ring said hook- shaped member having a threaded outer end and a nut threaded thereon and engaging the casing.
1,134,967	Apr. 06, 1915	Compression Space Annex for Internal Combustion Engine	Dalmar T. Brownlee	Indianapolis, Marion County, IN	Abstract: In many types of internal combustion engines, especially those which are used in motorcycles, the compression is very high and difficulty is therefore experienced in starting such motors. Many operators attempt to avoid this difficulty by opening the exhaust valves and spinning the motor very fast until there is momentum enough in the flywheel to carry the motor over its high compression stroke, This operation however, is one which requires considerable skill and strength. The object of our present invention is to avoid the difficulties outlined above by providing an internal combustion engine with an additional compression space which may be connected with or disconnected from the combustion chamber so that, when connected with the combustion chamber, the degree of compression while materially lessened, 3so nevertheless remains sufficient to make possible, without expenditure of great force, the ignition of the preliminary charges. Claim: As an article of manufacture, a compression-space annex for internal, combustion engines comprising a threaded stem having a valve seat formed at its lower end, a valve movably mounted in said stem and normally seated in said valve seat, at compression chamber carried by said stem and communicating with the bore thereof,a spring for normally holding said valve to its seat, and a cam arranged to operate said said valve to open the same.

1,136,376	Apr. 20, 1915	Crank Shaft	Fred W. Spacke	Indianapolis, Marion County, IN	Original application filed January 13, 1913, Serial No. 741,719. Divided and this application filed January 28, 1914. Abstract: Our invention relates to a crankshaft and to flywheel construction, as for engines, and has for its object the provision of a crankshaft and flywheels which shall be at once strong and compact, easily assembled, well lubricated, and balanced in operation. Claim: A crank shaft comprising two alined stub shafts provided with disks at their adjacent ends, the adjacent faces of said disks having aligned eccentric projections substantially parallel to the shaft axis, said projections being bored out taperingly with the large end in each projection toward the other projection, and a double ended doubly tapered bolt fitting in the bores of the projections and provided with nuts whereby the two parts of the shaft may be clamped together.

1,156,863	Oct. 12, 1915	Geared-Up Starter	Dalmar T. Brownlee	Indianapolis, Marion County, IN	Abstract: The object of my invention is to produce a starting gear for internal combustion engine of such character that it will be automatically thrown into and out of operative association with the shaft of the motor. Claim: The combination of a driving gear, a driven gear journaled upon a stud shaft, the said two gears having meshing spiral teeth and the driven gear being axially movable upon the stud shaft, and friction means arranged within the driven gear to lightly resist rotation thereof, the said friction means comprising a spring and friction block mounted in a transverse bore of the stud shaft.
