will enable others skilled in the art to which it appertains to make and use the same.

This invention relates toa device which may be properly termed a combined pr mer and humidifier, it being adapted for attachment to the instrument-board of an au: tomobile and being of such construction that it serves to supply air, water,'gas, or any v other fluids to the intake manifold of the I on'the planes of the lines 33, 4-4, and.

engine, either separately or together as may be desired. I

A further object of the invention 1s to provide a device of the above mentioned class which is simple, and novel, one which may be readily and easily, installed on the instrument-board by inexperienced persons, one in which the construction is such that it will greatly add to the efiiciency of the motor, one which will save gas and which will serve the function of a primer and an auxiliary air supply valve, which type of device will be found extremely useful and advantageous in cold weather.

Other objects and'advantages vention will be apparent during the course ofthe following description. 7 r

In the accompanying drawings form ng a part of the specification and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is anend elevationofadevice constructed in accoidancewith my nvention, the same being shown in position on an instrument-board, I Fig. 2 is a front elevation thereof- Figs. 3, 4, and.5 are sectional views taken 5-5 of Figs. 1, 2, and 4 respectively.-

In carrying out my invention, I employ a body member which is designed to be attached to the instrument-board of an automobile. This body member is provided with of the in-i,

adapted to sa W different iii-nab]? fluid to the outlet. .With 'thisconstruction the operator may supply air and water at the same time, or he may supply'e ach of the difierent 'kindsof fuel separately. The out.-

let referred to is in thefornio'fa short, '1 pipe, and it is adapted to be connected with a conduit which in turn is connected to the intake manifold of the engine.

In the drawings, wherein for fthe purpose of illustration is shown a preferred embodiment of my invention, the numeral 1 designates the instrument-boarded; an]

automobile, this board being provided with circular opening into which the *cylindrical portion of my improveddeyice is-dis;

posed. My improved device comprises a cylindricall'body membe '2. which is Pm,-

vided with a circular'fiange 3 by meansof which it is secured upon the instrumentboard 1. Extending from one side of the body member is a plurality of externally screw-threadedextensions .4, 5, and 6. Each extension is provided withv a longitudinal bore.i The bore 7 of the. extension. 5 is ,of' a greater diameter than the bore'sof the other extensions and it. terminates at (the center of the body 2ras shown more clearly in 'Fig. 4. On the other, hand, the 'bores '8 0f the extensions 4 and 6 extend entirely through the body andeach bore is enlarged at a point intermediatefi'ts ends to; provide v ashoulder 9 which inturn forms a valve seat. The enlarged portion of the boresS, is screw-threaded to permit the jscrewthreads of theneedle valveslO to have engagem'ent' therewith. Each 20f the valves 101's provided with aknurled head 11 by mean's'of which the valve is rotated. If desired, the outer face oftheheads 10 may be "labeled to indicate the kind of fuelthat each valve, controls; In-other words, it. is desirable to inscribe the word waterP-on one of theheads, while on the other head the word ga'so'lene will appear. *In, this way the-operator mayknow'whi'ch valvejto' i operate to supply a particular kind ofv fuelmay be stated thatqthe extensions 4aridv 6 are adapted toibe connected to supply lines. For instance, the extension 4 will beconnected with a pipe which leads to the gasolene tank, while the extension 6 will'be "connected with a pipe leading to a .watersup- Ply tankflr ang a suitebleplace in? the machine. As has been already indicated,

the extension 5 connects with a conduit which leads to the intake manifold of the engine. The bores 8 communicate with the bore 7 by'means of radial passages 12.

The body member in addition to being equipped with the already described parts,

is also provided with a third inlet opening 15, which is arranged in parallelism with theother inlet openings and opens through a side of the body opposite to that through which the outlet 7 opens. This inlet-like:

wise communicates with the outlet by means of a radial passage 12 audit is likewise provided with .internal 'screWthrea-ds with which'the screw-threads ofthe valve 18 coact. The valve 13 is novel, and is of a dif ferent construction from the already described valves. QExamination thereof will disclose the fact that this valve is provided with a longitudinal passage 14 which extends therethrough, and this passageserves to permit air to be supplied to the intake. manifold. 'It will be seen that by properly rotating the valve 13, the inner end thereof will abut the-closed inner end of the inlet opening 15, and in sodoingthe passage 7 lwill be closed and the air shut off. Due

-. to .the peculiar construction of this valve,

it will be seen that a small quantity of a.

. proper chemical such as etheror some other gas, serves thefunction of a primer.

explosive fluid, may be injected through the opening 14, and sucked into the intake mani-. fold, thus, an effective priming device for the engine is obtained with this construction. 'While I have. referred to this valve as being a priming valve, I wish it to be understood that as a rule, it only serves thefunction of an additional air supply valve, and the valve 10 which is labeled It being already understood how the different kinds of fuel aresupplied to the body and then to the outlet, it will be seen that in 7 air supplied to the intake may beeffectively regulated. I p "From the foregoing description it will be description taken in connection with the ao- I companying drawings will enable persons skilled in the art to which this invention appeitains, to obtain a thorough understanding of the construction, advantages, and operation thereof, therefore, further description is deemed unnecessary. by v It is to be understood that the form of my invention herein shown and described is to be taken as a preferred form thereof, and that various minor changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope ofthe subjoined claim. v

Iclaim: I i H y 3 A device of the class described comprising a substantially cylindrical body provided with an attaching flange adapted for connection to an automobile dash-board; a plurality of screw-threaded bored extensions projecting from the outer face of the body, a central extension serving as an outlet and having its bore extending into'and terminating at the center of the body, the bores of the remaining extensions extending en tirely through the body and being increased in diameter at points intermedi'ate their ends, forming shoulders which constitute valve seats, the enlarged portions of said last named bores being screw-threaded; screw-valves threaded into said bores andco op'erating with the seats; said body being also provided with another screw-threaded bore extending from its center and opening through its inner face, and with a. plurality V ofradial'passages connecting'all of the bores with said outlet bore; and a tubular screwthreadedstem extendinginto the last named. bore,'having' its inner end reduced in diameter and engaging the closed inner end of this bore. y y V I In testimony whereof I have hereunto set In hand.
