STARTING MECHANISM;

' Specification of Letters Patent.

Be it known that 1, WILLIAM L. TERRY, Jr., a citizen of the United States, residing at Little Roch-Arkansas, have invented certain new and useful Improvements in Start. ingMechanism, of which thefollowing is a nil, clear, and exact specification,

This inventionrelates to certain new and useful improvements in explosive engines,

and pertains more particularly to improved starting mechanism therefor;

The invention has for its object to provide 7 a simple and efficient mechanism for. starting the explosive engines of automobiles,

motor boats, and the like, without resorting.

to the usual method of cranking by hand.

. A further object is to provide an improved valve controlling the admission of" initial pressure to theengine cylinder, and

means for storing pressure for'imparting' initial movement to the engine, said pressure storage being also controlled by said valve. The invention will be hereinafter fully set forth and the claims.

In the accompanying drawings :'-Figure, 1 is a diagrammatic View illustrating my improvedstarting mechanism; Fig, 2 is a longitudinal sectional view of thecontro'lling valveyFig. 3 is atranSVerSe sectional of the valve. 7

Referring to the drawings similar letters of reference are issued to indicate corresponding parts in each of the views. y In my improvement the motor is preferably provided with four cyl nders a, a, a

and a which in addition to the usual Valvesand other gear controlling the admission of the explosive mixture, are each provided with pipes or conduits a a a, a leading to a valve casing B. Mounted in said casing is a sleeve 6 provided with ports b, 6 72 and b", controlling the outlets from pipes a a a, and a respectively. Leading from the cylinder a is a pipe 6 which communicates with the valve casing through a port 6 below the plane of the above-mentioned ports, and opposite said port I) is another port communicating Wlllh a pipe 12 leading to a storage tank C of any suitable or preferred construction. A check valve 6 is placed in the pipe 12 whereby the pressure in tank Cis maintained. A discharge pipe 6 leads fromthe tank 0 to the valve Applicationfiled July 13, 1909. seri no. 507,430

Said valve D is provided with an annular channel d inline-with port'l). Said valve 1 is also provided witha longitudinal channel d leading from the ohanneld to a point in line with ports'b', b*","b

and b and with 11 The shaft cl is shifted by means of a and a pin d engaging a effects a partial rotation of said shaft I and. said valve.

The operation isas follows: It is assumed] that the motor has been previously started by hand and is operating on the usual 'four cycle principle and that. cylinder (1' has U y of the explosive mixture through the'carbulreter and is compressing 6 b and b are closed, and the ports 7) and 'b" .are open. When the valve D arrives at the proper point to bring the ports I) and 6 into communication through channels (F01 and d which it will during a small part of motor, the minture under compression will be forced from pipe 6 throughpipe b to the tank G.

The valve closes ports I) and b fduring the firing or working stroke of the motor and prevents any chalice of back firing into the tank C, although said tankis preferably made strong enough to withstand anypres sure that. may cbme on. 1t frqm'this cause.

After the motor has run a short while, the sleeve 6 isshifted, either automatically by means of apressure regulator, (or by hand, so that all portal from motor aiid tank are closed. The tank is ready. 4 1' To start the motor, the operation is as follows; The sleeye or valve seat I) is moved so that ports 6 ,116 6 ,6, 6

By virtue of the annular port d on the valve D, port I) is in constant communication with tank through tube 6 when sleeve 6, is in starting the motor stops with one of the cylinders near the firing position, the valve D takesa position to put gas from the stored tank into the cylinder or cylinders about ready for started by throwing on the switch and firing the charge. 7

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States, 15 2- 1 l I l. A starting mechanism for explosive enines, comprising a pressure tank, means or charging said tank with fluid under pressure from one or more of the engine cylinders, means for distributing fluid under pressure from said tank to the engine cylina sleeve located therein and hav ng ports controlling the storage and distribution of said fluid under pressure, and a valve provided with channels cooperating with said ports.
