To all whom it may concern Be it known that I, BENJAMIN F. CLOUD, a citizen of the United States, residing at Cupertino, in the county of Santa Clara, State of California, have invented certain new and useful Improvements in Gas-Engine Starters; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to means for starting explosive engines without cranking and has for an object to provide a simultaneously actuated gasolene pump and air pump adapted to supply an explosive mixture under compression to the engine cylinders.

A second object of the invention is toprovide a novel distributer for delivering the explosive mixture to the engine cylinders.

With the above objects in view the invention consists of certain novel details of construction and combination of parts liereinafter fully described and claimed, it being understood that various modifications may be made in the minor details of construction within the scope of the appended claims.

In the accompanying drawings forming part of this speoification:Figure 1 .is a

side elevation of a portion of a four cylinder gas engine equipped with .my .invention. Fig.2 is a plan viewof the parts shown in Fig. 1. Fig. 3 is a cross sectional view taken on the line 3-3 Fig. 1. Fig. 4 is a cross sectional view taken on the line 4A: Fig. 1. Fig; 5 is an enlarged vertical sectional view through the gasolene and air pumps. Fig. 6 is a detail perspective view of the mixing device with the passages thereof shown in dotted lines. Fig. 7 is a cross sectional view on the line 77 Fig. 6.

Referring now tothe drawings in which like characters of reference designate simi-' lar parts, 10 designates an ordinary four cylinderautomob'ile engine. Threaded into the head of each cylinder is a pipe llwhich carries a T coupling 12, which is closed at the u per endby a threaded plug 13 and three ed into the lateral branch of this coupling is a four-way C(. nling 14. The upper end of the latter is c ;ed by a thread ed plug 15, the lower end isequipped with an elbow coupling 16, and the free branch is closed bya pet cock 1-7.

A valve seat 18 is formed at the meeting of the bores of the four-way coupling v nels.

leads mixture intake elbow 16, and when lifted by pressureof thestarting mixture establishes communication between the cylinder and intake elbow.

Each cylinder is equipped with the mechanism above described. For supplying the several mechanisms with the starting mixture under pressure adistributer in the natureof a-block 20 is employed, this block having. four interior channels 21 correspond- .ing to the four cylinders of the engine. The channels open through the outer faces of the block and are arranged. at right-angles to each other, and further all meet at the center of the block in a common opening 22. A set screw 23 is threaded into the block and is equipped with a pointed tip 24 which projects into the opening 22. An intake pipe 25 opens through the bottom of the block and discharges its=contents against the pointed tip of the screw, the tip thus forming a conical batlle which deflects the mixture in all directions uniformly into thefour chan- Conductor pipes 26 are connected terminally and respectively to the intake elbows 16 of the engine cylinders and communicate; with channels 21.

IA gasolene pump 27 is' arranged preferably on the. automobile dash 28, and inclose proximity to' this pump is arranged an air pump" 29, the piston rods of both pumps being connected by a yoke 30 which is centrally equippedwith a handle 81',

which forms means for simultaneously actuating both pistons, The gasolene pump piston is in the nature of a rod, this rod pump ing thegasolene by'displacement. The gasolene pump is provided with a cook 32 near the to A gasolene feed, pipe 33 which om any suitable gasolene supply is connected with the gasolcne pump near the bottom of the pump, this feed pipe having a check valve 35 to prevent retrograde move ment' of the gasolene and further having a manually operatable valve 36 to regulate the flow ofgasolene to the pump.

Both pumps discharge into .a common mixing device in the nature of a block 37 arranged below the pumps on the dash. Formed in the block is a vertical passage 38 which communicates with the discharge nipple 39 of the gasolene pump. This passage communicates at the lower end with a v stem and normally holds the valve closed.

'screW 46 disposed in the top horizontal passage 40 which opens out through the block at one end and is there closed by a plug 41, and which communicates at the opposite end with a vertical passage 42 having an enlargement formed With When closed the valve obstructs one end of a horizontally disposed passage 48 which extends longitudinally of the block and communicates with a vertically disposed,

passage 49 into which the discharge nipple 50 of the air pump is inserted. An outlet seen that where it encounters the passage 52 communicatesWit-h the passages 48 and 49 at their meeting and is connected to the intake pipe 25 of the distributer.

By referring now to Fig. 6 it will be upon depression of the "pump pistons the gasolene from the ga solene pump will be discharged against the valve 42 thereby lifting thelatter to permit escape of the gasolene through the passage 48 air discharged from theair pump and is thoroughly mixed there into the cylinders ready to take a The iniX-turemay be fired by advancing the W'ith, the resultant mixture escaping through the passage 52 and pipe. 25 into the distributer and from thence escaping charge.
