GAS-STARTER FOR INTERNAL-COMBUSTION EN GINES:
Specification of Letters Patent.
Patented Dec. 10, 1912.,
Application filed July 17, 1912. Serial No. 709,851.
To all whom it may concern:
Be it known that I, THOMAS J. McCARTHY, citizen of the United States, residing at Detroit, county of Wayne, State of 'Michi gan, have invented a certain new and useful Improvement in Gas-Starters for Internal- (lombustion Engines, and declare the following to be a full clear, and exact descrip tion of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to an improvement in gas starters for internal combustion engines, shown in the accompanying drawings .and more particularly set forth in the following specification and claims.
The object of my invention is to provide a device which may be secured to the dash board of an automobile or other location convenient to the engine,the construction being such that two chambers are provided adjacent to each other; one to receive gasolene and the other a'oharge of compressed air, the chambers communicating with each other and directly with the respective cylinders of the engine or with the manifold, or both.
A further object of the invention is to provide for the compression ofair in the gaso'- lene chamber of the device and in the air chamber adjacent thereto, and for the regulation of the volume of gasolene and air discharged from the respective chambers into a suitable mixing chamber from whichthe gas passes under compression to the several cylinders of the engine or its fuel feed manifold connected thereto.
Other advantages and improvements will hereafter appear.
In the drawings accompanying this'specificat1on:-F1gure 1 1s a central'vert cal section through the gasolene chamber of the device showing the pipe connectionbetween it and the respective cylinders of an internal combustion engine. Fig. 2 is a central vertical section through the gasolene and air chambers of the device, the section being at right angles. to that shownin Fig. 1 and on line 2-2 of Fig, 6. 'Fig. 3 is a side elevation of the device. Fig. at a plan view of the same. Fig. 5 is a sectional view of a detail showing the check valve to con trol back firing. Fig. 6 is an inverted.
is a central vertical section of a fragmentary portion of the gasolene chamber on line 8-8 of Fig. 6. Fig. 9 is a front elevation of a modification of the device. Fig. 10 is a vertical cross-sectional view of the same. Fig. 11 is a plan view of the modification shown in Fig; 9. Fig..12 is a cross-sectional g iew 9through the pump cylinder shown in ].g. Referring now to the letters of reference placed upon the drawings :'-A represents an internalcombustion engine; B its carbureter; C the fuel manifold connected with the carburetor and the respective cylinders of the engine; D the water circulating pipes leading to the radiator E. These several elements are of" the usual type are shown in order to disclose more clearly'the operation of my invention. 7
F is my'improved starting device and conslsts of a gasolene chamber H preferably formed of glass tubing in order that the volume of gasolene contained therein may be more readily determined. The tube is supported between an upper and lower plate I and I, the plates being joined together by suitable connecting-bolts J.
H is a filler cap, in the plate I by removing which the with gasolene or other suitable fuel.
- K is a compressed air chamber also preferably formed of tubing and supported between the upper and lower plates as in the case of the gasolene chamber,-a tight joint being secured in each case by employing suitable gaskets at the ends of the tubes. z and z" are flanges projecting from the respective plates I and. I, pierced'for the passage of bolts, by means of which the device is secured to the dashboard G of an automobile or other convenient support.
L is a reciprocating plunger pump mounted uponthe plate 1, its cylinder projecting into the gasolene chamber H.
1 L is the pump plunger from which rises a projecting stem Z, provided atv its outer end with a suitable knob or handle Z by which it may be manuall operated.
M is a check valve a aptedto close the port through the lower end of the pump chamber may be charged control of the valve 'gasolene chamber,
against the escape of air delivered into the by the operation of the plunger.
are springs which serve to force the check valve to its'seat.
N is a port in the plate I for'the passage of air from the gasolene chamber H into the compressed air chamber K.
' O is a port leading from gasolene'chamber H,-'the volume of gasolene that may be discharged being under the P is a port in the lower plate I to deliver air from the compressed air chamber K.
P" denotes a valve to regulate the volume of air delivered from the" compressed air chamber.
Q is a valve for controlling the delivery of air fromesaid chamber after passing'the valve 1 V Q denotes a valve for controlling the further delivery of gasolene after passing the valve 0.
Q indicates a handle controlling the operation of the valve Q, its valve stem being provided with a gear g meshlng with a similar gear g mounted on the stem of the valve Q ;-.-it willbe obvious that upon operatin the handle Q the valves Q and Q will die simultaneously actuated.
P is a port connecting the port P with the port 0 from the gasolene chamber, under the respective control of the valves Qand Q.
- P is a depending nipple leading into the mixing chamber P in turn connected with the port P P denotes a pipe leading from the nipple to the manifold P.
I are pipes leading from the manifold 1 to the fittings I? in turn connected with the respective cylinders of the engine. The fittingsP are provided with suitable ball or check valves P to insure against back firing. While I have not showna connec the valve' Q.
tion between the manifold P and the engine manifold C, the same may be provided if desired.
S is a. pressure gage connected with theair chamber K.
Having indicated the several parts by reference letters, the construction and operation of mydevice will be readily understood. The chamber H having been charged with gasolene through the opening closed by the filler cap 11, the valve 0' is adjusted to admit of a suflicient flow of'gasolene from the chamber through the port O,the too rapid flow of gasolene being controlled by The plunger pump L is then actuated to suitably compress the air inthe gasolene and air chambers, as indicated by the pressure age S, the check valve M closing upon eac operation of the plunger to maintain the ressurein the chamber. The valves Q and are then adjusted by operatgasolene released 5 the bottom of the tion circuit is now closed in the usual way :to fire the charge in the cylinder, thereby I 11, and 12, thepump 1 being provided with into the gasolene chamber; chamber being connected with the com pressed air chamber K by means of the port N, as in the construction previously de- I claim is [for compressing means for controlling the discharge of liquid from the fuel ing the handle Q whereupon the air from the chamber K passes out through the ports P and I under pressure, mingling with the the mixing chamber P, where an explosive mixture is formed which then passes through the nipple P by way of the pipe P to the manifold P and. thence by pipes P to the respective cylinders of the engine. The ignithrough the port 0 into causing the engine to turn over ;-'where- I upon it will, operate under its own power; It will be obvious that the check valves'I in the several fittings .Psserve to prevent back firing in'the several pipes Fleadingto the engine,' as previously explained ;'.-in' place of the ball checkshown any suitable form of check valve may be employed.
In the modification shown in Figs. 9, 10,
L is located at one side, of the gasolene chamber, its cylinder L an airport L connecting with the port L in the plate I leading scribed. A checlrvalve M controlled by a spring m, is provided in the port L to pre'-,-
the" gasolene vent'the return. of the air when forced into the gasolene and air-chambers.
