STARTER INTERNAL-COMBUSTION ENGINES.

To all whom it may concern: I

Be it known that we, Rosnn'r E. lonnnr and ARTHUR D. PooLnY, citizens of the United States, and residents, respectively, of the city of Chicago, county of Cook, and State of Illinois, and of the city oflVaukegan, county of Lake, and State of Illinois, have invented certain new and :useful Improvements in Starters for Internal-Cont bustion Engines, of which the following is a specification.

Our invention relates to improvements in. starters for internal combustion engines, and has for its object a device of this character which is of simple construction and etiicient in operation.

Our invention consists in the combinations and arrangements of parts hereinafter described and claimed.

@ur invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which-Figure 1 is a front elevation of a device embodying our invention, Fig. 2, a rear elevation of the same, Fig. 3, a longitudinal section of the device, Fig. l, a section taken on line :17-w of Fig. 3, and Fig. 5, an elevation of a valve disk employed in the device.

The preferred form of construction, as illustrated in the drawings, comprises a valve casing 1 provided with a standard 2 by means of which said casing may be mounted in any suitable or desired posi tion. Casing l is provided with a valve chamber 3 in which is arranged a rotatable valve disk 4: hav ng a port 5, shown. Casing 1 is closed by a cap 6 which is provided with a plurality of ports 7 there being a port 7 for each of the cylinders of the engine with which the starter is to be used. The form of construction illustrated. is designed for a four cylinder four cycle engine and therefore four ports 7 arranged at angles of ninety degrees are provided. A pipe 8 connects each of the ports 7 with a.

corresponding cylinder of the engine, said.

cylinders being connected in the order in which they are normally fired.

A shaft 9 is rotatably mounted in casing 1, as indicated, and valve disk 4: is keyed to said shaft so as to rotate therewith. Shaft 9 is geared to the engine shaft (not shown) to run in unison with the cylinders and the pistons of the engine.

.normal operative stroke.

operations of the Patented Apr. 21, 1914.

Serial No. 684,473.

Thus in the form illustrated, shaft 9 is geared to the engine shaft to run at one.- half the speed thereof, so. that said shaft will make one rotation for each complete operation of the cylinders and pistons. For a two cycle engine, shaft 9 would be geared to run at the same speed as the engine shaft,

since, in a two cycle engine, the cylinders and pistons operate in ,HDISOH with the engine shaft, that 1s, for each rotation of the engine shaft there is a complete operation of the cylinders and pistons;

The pipe 10 is connected with the valve chamber 3 in valve casing l and is provided with a check valve 11., as shown. Pipe 10 is connected with a source of compressed air or other starting fluid (not shown) so that valve chamber 3 and consequently port 5 will be constantly supplied with said starting fluid.

in use, shaft 9 is so connected or timed as to cause port 5 to register with each of the ports 7 successively and during the beginning and a large portion of the normal ope "utive stroke of the piston in the cylinder connected with the corresponding port 7'. In a four cylinder four cycle engine, unless the engine should happen to stop exactly on the dead center, there is always one piston which stops during this normal operative stroke, and it seldom if ever happens that a four cylinder engine stops on the dead center. This being so, and since port 5 registers with the corresponding port 7 during the operative stroke of the piston in the corresponding cylinder, when the engine stops, it will stop with port 5 registering with the port 7 which is in communication with the piston which stopped during its Thus, if compressed air is supplied through pipe 10, this piston and the other pistons successively will be caused to make their operative strokes by said compressed air and the engine thus started. "When the engine starts operating normally, the supply of compressed air to pipe 10 is cut oil and the engine peri'nitted to run under its own power. /Vhen the explosions begin in the engine cylinders, the compressed air will be excluded therefrom by the high pressure therein and thus not interfere with the normal operation of the engine cylinders. Check valve 11 auton'iatically closes to exclude the i the spark, as soon as an explosive mixture is formed, an explosion will take place and start the engine, after which each cylinder will be successively supplied with the acetylene gas and the operation of the engine continued. In this instance'check valve 11 prevents communication of the explosion or high pressure to the source of the acetylene gas supply.

While we have illustrated and described the preferred form of construction for carrvingour invention into eiiect, this is capable of variation and modification Without departing from the spirit of the invention. We, therefore do not wish to be limited to the exact details of construction set forth, but desire to avail ourselves of. such variations and modifications as come within the scope of the appended claim.

Having described our invention, what we claim as new and desire to secure by Letters Patent, is:

A distributing valve comprising a casing inclosi'ng a cylindrical chamber, one Wall of said casing having an internal annular recess therein located to one side of and concentric with said chamber, the outer periphcry of said recess being of less diameter than the periphery of the chamber, the wall opposite said first mentioned wall having spaced cylindrical ports disposed parallel with the axis of said chamber and registering with said recess, and the wall having said recess being provided with an inlet port substantially parallel with the axis of said chamber and opening into said recess; an operating shaft journaled concentrically in said casing; a disk carried by said shaft and snugly fitting the walls of said chamber said disk having a perforation therethrongh disposed parallel to and adapted to register consecutively with said cylindrical ports, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
