I o l v RALEIGH w. GODFREY, OF ELYRIA 01110, ASSIGNOR OF ONE-HALF T0 11. F. THoMrsoN, or LEXING ON,- onro. a r i ens-Enema STARTER. a l

To all whom it may concern;

. .Be it known that I, RALEIGH W Gon'rrmv, a citiv zen of the United States, residing at Elyria, in the cou'nty'of Lorain and'State of. Ohio, have inventedcertain new and useful Improvements in Gas- Engine Starters; and-do declare that the following is a full, clear, and exact description of the invention, which willenable-others skilled in the art to which it appertains to make and use the same. q

My invention relates to gas engine starters, and the invention consists in'a pump which is adapted to be connected witha gas engine cylinder, and to inject or spray a charge of gas orgasolene into the cylinder in a more or less-heated state to charge the same for starting, all=substantially as'shown and described and, particularly pointed out, in the claims.

In-the accompanying drawings Figure 1 is a plan view of a simple form of my new and improved starter or starting device, andFig. 2 is alongitudinal central sectional elevation" thereof. "Fig. 3 is a front end view of the barrel-showing the small channels therein for the discharge of the gasolene into the cylinder.

7 The device as shown in Figs. 1 and 2 comprises a tubular barrel Bhaving a chamber or receptacle 0 supported thereon substantially midway between-its endsand provided-with an opening 0 -in its bottom 'which communicates with the interior of said barrel.

A suitable cap cis: threaded into or upon the top of 'said chamber and may be provided with a gasket or the like to make the connection gas and liquid tight, but-still leaving the'said cap removable for the pur-, pose of filling the said'chambor with liquid,- presum-f ably gasolene or its equivalent.

' P n e D represents a plunger, which has it stem (I extending through the rear end of the said barrel and is pro-- vided with a handle d for manipulating the said A suitable stufiing gland E is provided at this end ofthebarrel about the said plunger stem to avoid leakage, and the said plunger is adapted to opcrate within the barrel back and forth in respect to the hole in the bottom of cylinder \C so asto open the same when a charge of gasolene or other explosive fluid is to be taken into the pump and to cut off the said supply and keep it closed while the plunger is being pushed forward to expel the gasolene from the pump. This requires that the said plunger be of such length that when the forward end of the stroke isreached it will still cover the hole'c and prevent the outflow of gasolene from the said chamber into the barrel behind the plunger.

- The front end of pump barrel B is threaded at b to be engaged inor withthe relief cock connection or directly with the rear of a gas engine cylinder as hereinafter described when charging is to be accomplished,

and the said end of the barrel is provided with aseries of'relatively long and fine or small channels 9 which are preferably shown herein as arranged in concentric circles and of such length as-to produce a rectilinear spraying effect when-the effect of this cqnstructionmay be said to be a direct or linear projection of the streams'of gasolene at c'onsiderable distance individually into the motor cylinder from said-channels instead of having the gasolene run together-at a short distance from the nozzle of theses barrel as occurs when the gasolene is forccd through a series of fine perforations in a disk or the like set into the end -of the barrel. In such case there is no lengthened projection or prolongation of the jets and they soon converge, into a more or less solid volume and defeat the more important object of diffusion and rapid yaporizationwhich it is imporant to obtain in a device of this kind to getthe desired admixture of air and gas and a prompt action in enplosion. Said channels 9 are traversed by a cut off valve G, which is adapted to,

be rotated axially and to be opened whena discharge of gasolene'is to be obtained and closed when the barrelis being charged with the gasolene and an end view of the nozzle of the barrel is shown in Fig. 3.

The channels 9 are continued transversely through u said valve, and the sittid channels are drilled when the valve G is'in open position so that they pass through' said valve and are cutoff when the valve is quarter turned,

H represents a heating pan or saucer, which is adapted to receive a -quantity of some suitable burning fluid or other combustible for heating the device to the requisite condition for starting purposes and this part as well as the others shown may be more or less modified to equivalent forms without departingfrom the spirit of the'invention. r v

Inoperation the device is heated and the plunger is drawn back to its limit, which opens hole 0 and per-v mits the barrel in front'of the plunger to'fill with gasolene or'vapor or both,;the valve G in the meantime 95,

being closed. Then thesaid valve is opened and the plunger is pressed to the front; and the gasolene forced in very fine streams, jets or sprays, liquidor vapor, through the channels 9 into the en 'ne cylinder, it

being presumed of course that the pump has first been screwed in place in the said cylinder ashereinbefore mentioned.- Meantime it is also presumed that the engine piston has been set so as to start the engine upon firing the mixture and that there is a quantity of airpresenter artificially supplied in into which the gasolene is injected.

Plunger .1) is adapted to be withdrawn a-greater or less distance beyond opening'c'to provide a larger or 7-,

plunger forces the liquid Possibly the main and essential 6D or i to the cylinder I05 smaller liquid chamber at the'front oi the plunger. The amount of liquid forced into the engine may be thus regulated to suit varying conditions.

Although the device is classed and described as a. starter for gas engines, it will be understood that it is adapted for use with any type otexplosive engine.

Whati claim is 2"- r 1'. A gas engine starter having a tubular pump barrel,

a liquid receptacle mounted on said barrel and having an orifice opening into said barrel, a plunger in said barrel adapted to traverse said orifice and a heating pan on the bottom of said barrel beneath said receptacle.

. 2. A gas engine starter adapted to be connected with an engine cylinder at its front end and comprising a liquid receptacle and a pump cylinder carrying said receptacle and open thereto, a plunger in said pump and u spraying outlet for said pump in direct line with said p1unger.'

3. A gas engine starter comprising pump and a liquid receptacle mounted thereon between its ends and open to said pump, said pump having a spraying discharge, and a heating pan beneath said barrel and receptacle.

'4. A gas engine starter comprising a liquid receptacle and a tubular barrel open thereto, a plunger in said barrel to force feed the liquid and said barrel having a series of outlets for the liquid at its front end and a valve adapted 2 5 to close said openings.

5. A gas engine starter comprising 0. liquid receptacle and a pump barrel open thereto, a plunger in said barrel adapted to control the flow of liquid from said receptacle to said barrel, a-sprnying nozzle for said barrel in advance 80 pan on the bottom of said In testimony whereof I sign this specification in the 40 presence of two witnesses.
