JOHN P. SCHWARTZ, OF RICHMOND, MINNESOTA. a

GAS-ENGINE PRIMER.

Specification of Letters Patent.

Patented Jan. 6, 1914.

Application filed May 26, 1913. Serial No. 770,009.

To all whom it may concern:

Be it known that 1, JOHN P. SCHWARTZ, a citizen of the United States, residing at Richmond, in the county of Stearns, State of Minnesota, have invented certain new and useful Improvements in Gas-Engine Primers; 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 art to which it appertains to make and use the same.

This invention relates to priming devices for gas engines and has for an object to provide an extremely simple and effective device for conducting the gasolene into the cylinder and directing the same onto the spark plug whereby the latter is cleaned of carbon while the gasolene for priming puro-ses is being passed into the cylinder.

A still further object is to provide a novel valve mechanism which may be operated from the drivers seat to control the passage of the priming gasolene into the engine cylinder.

A still further object is to provide a priming device which will be composed of a few simple and inexpensive parts that will be effective in operation and will not easily get out of order.

Vith the above objects in view the invention consists of certain novel details of construction and combination of parts hereinafter 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 drawing illustrating this invention :Figure 1 is a side elevation of the device. Fig. 2 is a longitudinal sectional view showing the device in operative position. Fig. 3 is a longitudinal sectional view showing the device in released position. Fig. 4 is a cross sectional view on the line 4-4 Fig. 2. Fig. 5 is a cross sectional view on the line 55 Fig. 2. Fig. 6 is a detail perspective view of the combined guide and guard.

Referring now to the drawing in which like characters of reference designate similar parts, 10 designates a cylinder of a gas engine, and 11 the spark plug carried by the cylinder.

Fixed to the cylinder is a bracket 12 having preferably three lateral arms 13, 14 and 15 which terminate in alined eyes that slidably receive a valve stem 16. A stop pin 17 is engaged transversely through the stem and is adapted to engage wit-h the arm 15 and limit movement of the stem toward the engine. A helical spring 18 is confined under tension on the stem between the arm 14 and the collar 19 of the bracket arm 20, and normally urges the stem away from the engine. The stem is formed with a conical tip which constitutes a valve 21, and is further formed longitudinally with surface grooves 22 preferably four in number as shown in Fig. 4 which extend from end to end of the stem.

A tank 23 that contains the gasolene for priming purposes, is secured in any suitable manner above the engine and is equipped in the bottom with an outlet pipe 24 having in the mouth a conical valve seat 25 that is faced with rubber 26 or other similar ma terial upon which the conical valve 21 seats, the rubber facing of the valve seat preventing leakage. The controlling spring 18 that is carried on the valve stem normally holds the valve seated, and upon movement of the valve stem against the pressure of this spring, the valve is opened with a resultant gravitation of the priming gasolene down through the grooves 22 of the valve stem.

A collar 27 is secured to the outlet pipe 24 by means of a set screw 28 and is provided with spring arms 29 arranged in the form of a corolla, these arms entering the grooves 22 of the valve stem and when the valve is opened performing the function of guides to direct the gasolene into the grooves and at the same time performing the function of guards which prevent the gasolene from escaping outwardly from the conical valve.

A stem 30 is slidably fitted in an opening formed in the cylinder adjacent to the spark plug 11, the stem terminating in an enlarged conical valve 31 which is normally held seated with the base against the inner wall of the cylinder by means of a helical spring 32 that is confined on the stem under tension between the cylinder and a stop pin 33 engaged transversely through the stem, whereby loss of compression when the engine is running is positively prevented. The valve stem 30 is in alinement with the above described valve stem 16 and upon depression of the latter the valve stem 30 is depressed against the tension of its controlling spring 32 whereby the valve 31 is moved away from the cylinder wall. A series of grooves 84 are formed longitudiwith the tip of the valve 31 and has the smaller end disposed to discharge the priming gasolene on to the spark points of the spark plug, whereby the points are cleansed of deposits while the priming gasolene is passing into the cylinder. 7

For depressing the valve stem 16, a push rod 37 is engaged through an opening 38 in the floor of the automobile or like vehicle and is equipped with a head 39 by means of which the rod may be depressed by the foot, there being a helical spring 40 confined under tension on the rod between a wear plate 41 on the floor and the head 39 of the rod, which spring normally holds the rod at its outer limit of movement in released position. An angular lever 412 is pivoted at the elbow 43 on any suitable stationary support and has one leg pivotally connected as shown at A to the push rod 37 and has the other leg connected by means of a link 45 to the above mentioned bracket arm 20. Upon depression of the push rod the angular lever will be rocked on its pivot with a resultant clepression of the valve stem 16 whereby the valve 21 and the valve 31 are both opened to facilitate passage of the priming gasolene into the cylinder as above described.

What is claimed, is

1. The combination with a gas engine cyltank, and a connection between said valve and said funnel operating to conduct the contents of said tank into said funnel upon opening of said valve.

2. The combination with a gas engine cylinder, of a priming device including a tank having an outlet pipe, a manually controlled spring'pressed valve normally closing said outlet pipe and having longitudinal grooves,

a plurality of fingers projecting from said pipe into said grooves and directing the contents of said tank into said grooves upon opening of said valve, and means for conducting the contents of said grooves into said cylinder upon opening of said valve.

3. The combination with a gas engine cylinder, of a valve in said cylinder, a tank for priming fluid, an outlct pipe connected to said tank, a manually operatable spring cont-rolled valve normally sealing said outlet pipe, depression of said valve against the pressure of its spring serving to open the valve carried by said cylinder, means for holding said cylinder valve normally closed, both of said valves being formed with longitudinal registering grooves adapted to conduct the contents of said tank longitudinally of said valve and into said cylinder.

In testimony whereof, I aflix my signature, in the presence of two witnesses.

JOHN P. SCHWVARTZ.
