COMBINED GAS-SAVER AND PRIMER FOR AUTOMOBILES.

Application filed May s, 1918.

To all whom it may concern: Be it known that we, ORA E. Bnnnonons and Emma D. BURROUGHS, citizens of the United States, residing at Argos, in the 5 county of Marshall and State of Indiana, have invented certain new and useful Improvements in Combined Gas- Savers and Primers for Automobiles, of which the following is a specification.

saver and primer for automobiles.

The object of the invention is to provide adevice operable by a single lever from the dash of a car to supply a priming mixture air from the exhaust manifold to the intake manifold of the engine, where by the motor may be easily started and a saving in gas effected.

Another ob ect is to provide improved means for automatically controlling the priming charge operable the engine.

With the foregoing and other objects in View, which will appear as the description by the vacuum of proceeds, the invention residesin the. combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the in vention herein disclosed may be made within the scope of what is claimed without departing from the sp1r1t of the invention.

In the accompanying drawings Figure 1 represents a side elevation of the 3 device constituting this invention with parts broken out,

Fig. 2 is a longitudinal section through the valve, and 1 Fig. 3 is a vertical section through the primlng charge controlling device.

The preferred form of the invention illustrated herein comprises a valve casing 1- havin a tapered valve plug 2 therein which exten s through the casing and has a coiled bearing against one end of the casing and a pin 4 extended through the projecting end of the valve so as to hold the valve normally in connection with its casing as is shown clearly in Figs'l and 2.

Leading from the valve casing l is a pipe 5 connected at its other end with a shell-like member 6 which is designed to fit over the exhaust manifold of ail-internal combustion engine and to be clamped or secured thereto This casing 6 colexhaust manifold Specification of Letters Patent.

This invention relates to a combined gas the valve casing 1 at the side Patented Dec. 9, 19115). Serial no. 233,383.

'and passes it through casing l for a scribed.

Another pipe 7 opens through one side of the valve casing 1, being here shown with longitudinal alinement in the opening in which pipe 5 is mounted. This pipe 7 is detachably mounted in the valve casing l and carries at its upper end a priming charge controlling device 8 here shown in the form of a cylindrical container 9- having a plug 10 detachably connected on its lower end a11d carried by pipe 2", said plug having a valve seat 11 therein. Another plug 12 closes the other end of the cylinder- 9 and has a valve seat 13. with a pipe 1a leading therefrom and adapted to be connected with a fuel supply opening, not shown.

A pair of ball valves 15 and 16 are mount ed in the losures 10 and 1a and open in opposite Cllft. ons, being connected by a stem 17. A coiled spring 18 is mounted in pipe 7 and operates to hold the valve 16 normally in closed position and the valve 15 open so that the fuel, preferably gasolene of a high grade, may flow thereinto through pipe-14 from the supply tank. When the valve 16 is opened by suction from the engine against the tension of spring 18, the valve 15 is purpose presently to be de closed thereby cutting off communication between the cylinder 9 and the tank and pen nntting the contents of sald contamer to pass out through pipe 7 and through valve 2 to the intake manifold, not shown, when the valve 2 is properly turned to bring the pipe 7' into communication with the passage 19 formed therein and which is here shown L- shaped (see Fig. 2).

The valve 2 has another L-shaped passage 20 arranged at right angles to the passage 19 and which is designed to be brought into.

communication with the pipe 5 on the turn ing of the valve 2 in the proper direction, the two passages 19 and 20 being so disposed that when one of these pipes is opened the other is closed. These passages 19 and 20 are designed to alternately communicate with an lL-shaped pipe 21 which leads from diametrically opposite and intermediate the space between the points where the pipes 5 and 7 enter. This pipe 21 is designed to be screwed into the intake manifold of an internal combustion engine, threads 22 being here shown for such connection. pipe 21 has an apertured extension 23 ar- The free end of-this pipe 5 to the valve ranged beyond the threads '22 which is designed to eXtend into the intake manifold for the passage of the combined air and gas and operates to spray or break up the fuel particles to facilitate their volatilizationt lhe larger end of valve 2 is connected with a lever 2%, being here shown pivoted thereto'to hold against turning in relation to the lever. suitable point convenient for operation by the driver of a car and is designed to be turned for turning the valve 2 in the casing 1,-to bring either the passage 19 or 20 into operative relation to connect its cooperating pipe with thepipe 21, when desired.

From the above description it will be obvious that when the lever 24: turned to bring the passage 1.9 into the position shown in Fig. 2, communication will be afforded between pipe 7 leading from the priming device to the pipe 21 leading to the manifold. When this valve 2 is so positioned, the turning over of the motor will produce a vacuum in the engine causing suction through the intake manifold, pipe 21., passage 19 and pipe 7. This suction will operate to open valve 16 against the tension of its spring 18 and close valve 15. When this occurs. the charge contained in the cylinder 9 will flow out through pipe 7, passage 19, and pipe 21 into the manifold, being broken up and sprayed as itpasses through the perforated extensions 23 of the said pipe .21. After the engine has been started, the valve 2 is turned through the lever 24 to cut off the communication between passage 19 and pipe 7, and if desired, the valve 2 may be turned to position passage 20 so that it will be brought into communication with pipe 5 and pipe 21. iVhcn the parts are so disposed the'hot air collected in the casing 6 will be drawn through pipe into the 'inanifold and operate to combine with the fuel to rarefy it and operate as a gas saver in a well known manner.

From the above it will be seen that the priming and gas saving devices constituting this invention are both operated and con trolled by the same lever from a point convenient to the driver and that the amount of the priming charge is automatically regulated after the priming valve is opened from the dash. Furthermore, the charge is drawn into the intake manifold by the This lever 2% extends to any vacuum of the engine and not forced into as is the manner in devices of this character ordinarily employed. h

It is of course to be understood that this device may be constructed to fit the different manifolds of various cars and that it is not limited for use in connection with any particular car.

The foregoing description and the drawings have reference to what may be considered the preferred or approved form of our invention. It is to be understood that we may make such changes in construction and arrangement and combination of parts, materials, dimensions, at (LL, as may prove expedient and fall within the scope of the claimed invention.

Having thus fully described our invention, what We claim as new and desire to secure by Letters Patent, is

lin a device of the class described, the combination of a valve casing having a bore tapering toward one end With two longitudinally spaced openings in one side wall, and another in the opposed wall at a point opposite the middle of the space between said first-mentioned openings, a tapered plug valve extending through said bore and provided with a reduced. extension at its smaller end projecting beyond said on ling, ,a-coiled spring on said extension to cold the valve in close contact with the casing, a pipe leading from one of said first-mentioned openings and equipped with a hot air collector, another pipe opening into the other of said first-mentioned openings and provided with an automatically controlled priming device, a pipe leading from said intermediately disposed opposed
