PRIMING DEVICE.

Specification of Letters Patent.

Patented Uct,

Application filed April 23, 1918. Serial No. 23042251- To (/71 whom it may concern:

Be it known that we, Josnrn War. Ln Mann-1 and Haney L. \Vlccnmrs, citizens of the United States,-and residents of the city of New York, in the county of New York and Queens, respectively, and State of New York, have invented certain new and useful Improvements in Primin Devices, olf which the following is a specihcation.

The present invention relates to improvements in starting devices for internal combustion engines, and moreparticularly to that. type of starting devices which is intended to be used with engines upon motor vehicles, although it Will be understood that it is applicable to engines used in other connections.

The main object of the present invention is to provide an improved device, by the use of which a snllicient amount of gasolenc, to prime the engine, may be introi'luced into the cylinders of the engine, without the necessity of opening the hood of the motor vehicle to turn the pet-cocks of the various priming cups.

A further object of the invention is to provide a device of the character specified which is conveniently accessible to the driver without leaving his seat, the device being of such a character that it may be operated by simply pulling a handl located in lront of the drivers seat.

A still further object of the invention is to provide a device of this type which may be applied easily to existing motor vehicles as well as to new vehicles, and which is relatively inexpensive and adapted for Inanut'ao ture on a commercial scale. v

With these and other objects in view, will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement, and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it

being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention,

One of the many possible en'ibodiments of the invention is illustrated in the accompanying drawings, in which Figure l is a side elevation of a priming device constructed in accordance with the present invention; Fig. 2 is a longitudinal vertical section taken therethrough; liig. 3 is a top plan view of the same with some of the elements in other positions; and Fist". *l a section taken on line lr loi l ig. n.

In the drawings, the numeral lt iiltill a reservoir, adapted to contain a suitable lupiid llyt ll'ficill'llilll, such as Q'LISUiOllt, which is tilled into the said reservoir through a nipple ll, covered by a cap t2, the latte-i.- being provided with a vent hole 12'; This reservoir is attached in anv suitable manner to the dash-board, when the engine is applied to a motor vehicle, and is, preferably, disposed below the hood of the vehicle. I The reservoir is provided with a small :iuel outlet 3, communicating with the cylinder it of a pump, that is shown in the drawings as being made integral with the said reservoir, although it may be secured thereto in any suitable manner. The pump cylinder ex tends through an opening 15 in the dash board l t, and is provided with a rear head 17 and a from head 18. A little distance in rear of the front head 15 there is formed in the cylinder a partition 15), exlemling at right angles to the longitudinal axis of the said cylinder and dividing the same into a piston chamber 20 and a compartmcl-it 21, the latter communicating through the fuel outlet 13 with the reservoir 10. "The partition 19 has an opening 22, through which the piston chamber eonununicali-s with the compartment 21. In th from head 18 is formed a perl'oralion 23, with which cooperates an inwardly opening spring-pressed check valve 2 t, for a purpose hereinafter to be de scribed.

In the piston chamber is mounted a piston 25 of any suitable construction, the said piston being secured to a piston rod 26, that extends through the rear head 17 and terminates in a handle 27, To this handle and to the rear head 17 are attached helical springs 28, which have a tendency to hold the piston in its forward position, that is to say at the beginning of its suction stroke.

The compartment 21 is provided with a discharge opening 29. controlled by a cock 30, the outlet of which is connected by a pipe 31, preferably, with the manifold of the internal combustion engine, with which the priming device is intended to cooperate. To the plug 3'2 oi the cook 30 is pivoted at 33 an actuating bar 34. that extends rearwardly in parallel relation to the piston rod through the dash-board'ltl, and is pro vided with an arm 55, the latter being seated in alongitudinal slot 36 in the piston rod, 1 arrangement being such that, when the :on i in its forward position 9), i arm 35 abuts against the rear ecge 37 ot' the slot and the cock is in its closed iosition. The slot 36, on the other hand, :5 of a length. that its front edge 38 comes nto contact with the arm innnediately erore the piston completes its suction thereby shifting the said arm as the stroke is being completed and thus urning the plug of the cock communication between the 29 and the pipe 31. ion of this device is as fol "shining that the piston is in its L L position (Fig. 2), obvious y the rah eld by its spring in its es the piston is drawn v, the said check valve is unseated,

vvh be drawn into the compartston chamber 20, which air iuei. therein. The cock 3O closed position until the piston coinpleted'its suction stroke and in 35 comes into Contact with edge 38 of the slot 36 in the piston I hen, upon completing the suction "1e said oiston rod causes the actuto more with it, thereby giving turn to the cock plug 32 and opencoininunication between the compart- 21 and the pipe 31. As the piston is it on its suction stroke, the springs 28 y QXPtUEClH It, therefore, upon the completion of the suction stroke of the i on the handle "2? l it free, the springs l cause the said piston to move in the e direction, that is to upon its suc ieu partially tie ' stroke. As soon as the expelling, started, the check valve 2i closes n and the fuel Within the e injected into the pipe 31, n left pen until the rear edge 01TH; into cimtact with the mating bar ii and shifts the continued move- :to its closing pos (ion,

tion engines, including a 31 the fuel flows into the intake in the pipe it is drawn into the manifold, from which cylinders of the engine.

Although a single operation of the primer should be suflicient under ordinary conditions, the operation can bei'epeated as often I as desired according to the requirements. it is to be observed that a measured quantity of fuel is'fed during each operation to the engine cylinders,the quantity depending upon the size of the pump cylinder.

What We claim is-- 1. A priming device for internal combustion engines, including a cylinder having an inlet opening communicating With a supply of liquid hydro-carloon and a valve controlled discharge opening, a piston in said cylinder, a piston rod fixed to said piston having a longitudinal slot, an actuating bar pivoted to the valve controlling said discharge opening having an arm extending into said slot, whereby said valve h ought to its open position near the end of the suction stroke of said piston in said cylinder and to its closed position at the end oi the stroke of said piston in the opposite direction.

2. A priming device for internal combusreservoir for containing a supply of liquid hydro-carbon, a cylinder having a piston chamber and a compartment communicating with said chamber and with said reservoir, said coinpartnient being provided with a valve controlled discharge opening, a piston in said chamber, a piston rod fixed to said piston having a longitudinal slot, an actuating barpivoted to the valve controlling said'discharge opening having an arm extending into said slot, whereby said valve is brought to its open position near the end of the suction stroke of said piston in said cylinder and to its closed position at the end of the stroke of said piston in the opposite direction.

Signed at New York, in the county of New York, and State of New York, this 18th day oi April, A. D. 1918.
