Application filed November 4, 1912. Serial N 0.

To all whom it mag concern:

Be it known that I, JOHN L. PARKES, a citizen of the United States, and a resident of Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Engine-Priming Devices; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawings, and to the numbers of referwhich form a part of this specification. This invention'relates to improvements in starting or priming devices for internal combustion engines, and has particular reference to improvements in priming devices for gas or gasolene engines.

It is an object of this invention to provide an engine priming device of simple construction, consisting of but few parts, and adapted to automatically and posltlvely close the passage connecting the supply of priming fluidv with the engine, when the device is not in use, and to be arranged or mounted in a number of diflerent relative positions.

It is a further object of this invention to provide a priming device for hydrocarbon engines, which can be easily and quickly installed, and which carries within itself the supply of priming fluid.

It i also an object of this invention to provide a manually operable pump, particularly adaptedfor forcing the priming fluid from .the supply reservoir to the engine, which shall be of simple construction, and which shall carry within itself a positive shut off cock automatically closed when not in use, and which is so associated with a supply vessel of priming fluid removably secured thereto, that the whole presents a compact and neat appearance, which can be easily and quickly installed for use.

The invention consists in a priming device for internal combustion engines. embracing a combined pump and shut off cock associated with a supply of startingfluid and connected to deliver hydro-carbon to the engine.

The invention further consists in a pump of simple construction, having inlet and discharge passages connecting with its base, and having its plunger formed to positively close said passages when the pump is not in operation.

fluid to the undue Waste, and I there-.

into the inlet manifold of the conical 0 engine at such a point that the fluid will beinstalled with the least amount of labor, and

furthermore, as the intake manifolds are usually maderof cast metal, it is necessary to drill or make an opening therein through which to insert the supply pipe, and I have deviseda unique pipe connection only facilitates the installation of the device, but further acts to direct the starting fluid within the manifold in the direction which will materially assist in causing the primary fiuid to enter the-cylinders.

In said drawings A represents an automobile engine installed in position and provided with an inlet manifold B.

C represents generally, the combined pump and reservoir, which is connected to the manifold 13 by means of the pipe D.

As shown in Figs. 1 and 2, the pump 2, is arranged in vertical position and the reservoir 3, is mounted upon the lower end of the pump and depends therefrom. The device itself is mounted upon the dashboard 4, of the automobile by means of a suitable clamping bracket 5. The pump 2, comprises a cyl-- inder 2 within which is mounted a hollow plunger 2", which projects from the upper end of the cylinder 2, having upon its upper or outer end an enlarged handpiece 5, by means of which the plunger can be operated Within the cylinder. The upper end of the cylinder is closed by means of a suitable adjustable packing 6, which elfectually prevents the escape of any fluid at this end of the pump. The cylinder of the pump is mounted at its lower end upon a base memher 7 which is provided with a central conical cavity 8, adapted to receive a similarly shaped head 9, provided upon the lower or inner end of the pump plunger 2". This base 7, is provided with two substantially identical nozzles 10 and 11, projecting therefrom and arranged, one in substantial axial alinement with the pump cylinder and the other arranged to project substantially at right angles thereto. The projection 10, is provided with a central passage 12, which opens at its inner end into the base of the ening 8 and the nozzle 11, is provided with a similar central passage 13, opening through the side wall of the conical opening 8. The head 9, of the pump plunger is conformed to the conical opening 8, with a valve fit so that when the pump plunger is forced to the lower limit of its movement and the head 9 is seated in the conical opening 8, in the manner of a coniwhich not cal stop cook, it effectually prevents the flow of liquid from the inlet opening 12, to the outlet opening 13 or vice versa.

The body 3, of the reservoir 3, is made of glass or any other suitable material, and is provided with a metal cover 14. The cover is secured to plug 15, adapted to be mounted in a threaded opening 16, provided in the projecting nozzle 10, and in direct communication with the inlet passage 12. As shown, the plug 15,

reservoir, are provided with engaging screw that the glass reservoir can threads 21, so be readily removed from the pump for cleaning and filling.

A bail 22, is pivotally mounted on the base 7 of the pump in position to surround the reservoir and bear upon its lower end and thereby prevent the unscrewing of the reservoir 3, from the cover 14. The center of the pivotal connection of the bail with the base is arranged at the intersection of the center line of the two nozzles 10 and 11, and these nozzles are equal in length from this intersection. The pump is made in this manner so that the reservoir can be interchangeably mounted upon the nozzle 10, as-shown in Figs. 1 and 2, or upon the nozzle 11, as shown in dotted lines in Fig. 1, and in full lines in Fig. 5, the bail 22, serving with equal efficiency to prevent the removal of the reservoir in either of its positions. prises a flat strip'of spring metal bent into U form and having its ends arranged for proper connection to the base 7. When in its normal position it bears upon the lower end of the glass reservoir and thus prevents it from becoming loosened. The bail is of such shape that it can be readily lengthened to a sufficient extent to permit it to be rotated on its pivots to free it from the glass reservoir for the purpose of permitting the removal of the reservoir, and for this purpose the sides 23, of the bail are bowed, as clearly illustrated in Fig. 3.

It is obvious from the construction described that the bail may be removed from contact with the glass reservoir by pressing the side members 23, of the bail toward each other, thereby permitting the bail to 'be swung free of the reservoir.

The nozzle 11, as shown in Fig. 2, receives the pump by means of a screw The hail com-' a screw threaded connection 24, which carries a check valve, similar to the valve 17, mounted in the connection 15, and serves to prevent the return of the starting fluid which has been forced out of the pump 3, into the pump cylinder and force it through the pipe D, to the engine, and that when the pump is not in use, if the plunger is forced to the inner limit of its movement, it will effectually prevent the return of the starting fluid from the pipe D, into the pump or into the reservoir 3. To prevent the possibility of the plunger not being returned to the inner limit of its movement, a light spiral compression-spring 25, is provided, which is mounted within the cylinder 2" of the pump and is adapted to bear at its inner end upon the upper end of the head 9, consequently the plunger 2 will be aut0- matically returned by the spring 25, to the Y inner limit of its movement regardless of the position in which the operator leaves the plunger. A small relief passage 26, is provided through the plunger head 9, which opens to its end through the inner end of the head 9, and .at its other end opens into the vpump cylinder 2. The relief passage 26,

serves two purposes, it prevents the possible accumulation of fluid above the head 9,

which might prevent the easy operation of the pump and it further serves to permit the outflow of liquid from beneath the plunger into the cylinder when the plunger is forced to the lower limit of its movement. If the liquid was not-released from beneath the head 9, it might serve to prevent the final seating of the head in the conical opening 8.

In order that the device can be easily and conveniently installed in connection with automobile engines, a unique pipe connec- -tion E, is provided by means of which the pipe D, can be connected to the manifold B. As shown the connection E, comprises a screw 'thread pipe nipple 30, adapted for convenient connection at one end with the pipe D, and which has pivotally mounted on its other end a cross bar member 31, which has a cross section of U-form and may be ar ranged within the manifold B, in longitudinal position as indicated in dotted lines in Fig. 1, and as also shown in Fig. 8. The cross bar member in such position serves to break up and direct the flow of priming fluid from the nipple 30 longitudinally of the manifold B, directing it toward the cylinders of the engine. The cross bar 31. is mounted upon the inner end of the nipple by 'means of a Divot pin arranged somewhat nearer one end of the cross bar than the other. In mounting this connection l), in a manifold, a hole 33, is provided in the 1nanifold; in proper position to receive the cpnnectl'on, and as clearly illustrated in Fig; 110, when the connection is entered through the small discharge openings 36, therein, which are arranged to emit the starting fluid longitudinally of the U-shaped cross bar 31, toward both ends thereof. For the purpose of making a tight joint between the connection E, and. the manifold, a curved metallic Washer 37, is provided, and beneath the Washer is provided a soft Washer 38, made of asbestos or other suitable material. As shown, the metallic washer 37, is curved substantially tothe curvature of themanifold so that when pressed against the soft Washer 38, by the nut 34, it will serve to make a tight joint betweenthe nipple and the outer surface of the manifold. Fig. 6 illustrates a modification of the device for holding the reservoir 3, in place. This device is similar to the bail 22, in that it is similarly pivoted to the base of the pump, but instead of being carried completely around the bottom of the reservoir, it is provided with a resilient clasp member 39, which is adapted to clasp the body of the reservoir. Said clasping member 39, is secured to the side bars 23, of the bail, which, as shown in Fig. 7, is U shaped, and is adapted to be sprung over the cylindrical body of the receptacle and clasp it with suflicient pressure to prevent it from becoming loosened from the screw cap 14.

Fig. 5. shows the device C,installed on a dash board 4, with the pump cylinder arranged in horizontal position instead of in vertical position, as illustrated in Figs. 1 and 2, and when arranged for such installa-' tion the reservoir 3, is changed from the lower end of the pump, as shown in Figs. 1 and 2, to the side connection 11, and obviously the two ball check valves which serve to prevent the return of the starting fluid from the pipe I), to the reservoir 3, are also reversed in position. The only change in the construction of the pumpfor the installation shown in Fig. 5, is that clamp 40, is of slightly different form from the holding clamp 5, shown in Figs. 1 and 2.

The operation is as follows: In using my device the reservoir 3, having been "supplied with starting fluid and the device having been installed in position, it is only necessary to actuate the plunger 2 outwardlv and inwardly, each outward stroke drawing liquid from the reservoir and each, inward stroke forcing the liquid from the, pump loo cylinder into the manifold of the engine and distributing it longitudinally therein. It is obvious that instead of providing the pump with a small individual reservoir carried thereby, the intake 19, could be extended to some other source of supply of starting fluid such as thesupply pipe X. There are, however, certain advantages to be gained by the use of the individual reservoir arranged in position to be conveniently inspected. In the first place it is convenient with the use .of such a reservoir to use a more volatile fluid for starting the engine than is provided for its fuel supply. This feature is convenient particularly for starting engines in cold Weather, asthe gasolene which is ordinarily used at the present time is not likely to be of such a quality that it can be volatilized easily enough to start the engine without delay. Another advantage is that the amount of starting fluid which the re ceptacle contains can be easily seen at any time. The pump having been operated to discharge the priming fluid from the reservoir into the manifold of the engine, it is not necessary to manually operate any valves for the purpose of shutting off completely the connection between the reservoir and the manifold as the spring 25 automatically forces the plunger 2 to the lower limitof its movement seating the head 9, in the conical opening 8, and completely shutting off connection as hereinbefore described.

It should be understood that in the use of a device of this character, a positive shut off valve is an essential element for the reason that after the engine has been started the suction of the cylinders upon the inlet inani- .fold of the engine will be transmitted to the auxiliary reservoir through the connecting pipes. Should this action be permitted the liquid fuel would be drawn through the ump into the manifold and :would seriously disturb the action of the engine. The automatic closing of the positive shut off valve in my device relieves the operator of any necessity of manually closing the connection between the auxiliary supply and the engine,-as he is assured that once he has primed the engine and released the pump plunger no further fuel can enter the inlet manifold from the auxiliary supply.

/Vhile my invention is particularly adapted for use upon an automobile, it will be obvious that it is not limited to the production of a priming device for this particular use, and furthermore, while I have shown my device as being provided with a reservoir attached to the pump, it willbe equally obvious that the function of-the device, in so far as it relates to the forcing of a starting fluid into the manifold of an engine, can be performed with equal facility by connecting the pump directly or indirectly to a larger supply of gasolene or other starting fluid,
