Application filed September 9, 1924. Serial No. 736,758
To all whom it may concern:
Be it known that I,'GEORGE W.. MERGER, a citizen of the United States, residing at Muskogee, in the county of Muskogee and State, of Oklahoma, have invented certain new and useful Improvements in Auxiliary Air-Admitting, Decarbonizing, and Priming Attachments, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to accessories for or attachments to internal combustion engines and has for its object the provision of a device formed as a unitary structure and adapted for interposition between the carburetor and the intake manifold of the enine whereby to permit the inlet of auxillary or additional air to the manifold, to allow the injection of a suitable liquid for the purpose of loosening and removmg any accumulation of carbon within the motor, and to effect priming whereby to facilitate starting when the motor is cold.-
A vital feature is the provision of a de-. vice of this character which 1s provldedwith a well, basin or storage recess within which gasoline vapor or spray condensing within the manifold subsequent to stopping of the motor may automatically collect or accumulate and remain so as to be in the most advantageous position possible for supplying a rich mixture to the carburetor for effecting starting of the motor under low temperature conditions.
Another object is the provision of a device of the character mentioned having control means wherebythe amount or "flow 0f the auxiliary or additional air may be regu lated, an element being provided which leads through the dash or instrument board of the vehicle so that adjustment may be made from the drivers seat.
A still further object is the provision of an attachment of this nature in which the air passage is so related to the flow of fuelwhich may be installed without involving the making of any changes, which will be positive in action, eflicient and durable in SBIVlCi-l, and a general improvement in the ar With the above and other objects an dad .tor B having an intake manifold C leadin from the carburetor D. The letters E and F represent. the flanges on the intake manifold and carburetor outlet respectively,
which flanges are connected ordinarily by studs G. The'letter H represents the instrument board or dash of the car. 1
In carrying out the invention, I provide a unitary structure which includes a body 10 here represented as of substantially diamond shape to conform to the shape of the flanges E and F and which is provided with a pair of holes 11 for the passage of the studs G whereby the body may be secured between the flanges so that the fuel mixture from the carburetor must pass through the device before reaching the manifold C. At its center the body 10 is formed with a relatively large circular opening 12' within which is mounted a wire screen or gauze 13 held in place, as for instance, by
means of a split expansible spring ring 14 seated within a groove 15.
Formed integrally upon .the upper. edge of the body 10 is an extension or conduit "'16 which is preferably inclined at its lower end with respect to the vertical axis of thedevice but. which has its upper end preferably vertically arranged. At the upperend of this extension is a oup or enlargement 17 from which leads a ,bore or passage 18 extending entirely through the extension 16 and through the upper portion of the-bodyv into the opening 12.. It will be observed that the lower end of this passage angles back at an angle of substantially 7 more or less, for a purpose to be described.
At a point intermediate its length the extension 16 is formed with an enlarged portion 19 constituting a valve body and having a tapered opening 20 intersecting the passage 18 for the accommodation of a rotary tapered plug 21 having a handle 22 and carrying an abutment 23 engaged by a coil spring 24 which bears against the enlargement 19 for the purpose of holding the plug resiliently to its seat or in proper close fitting engagement with the wall of the opening 20 to prevent leakage. The plug 21 is provided with a transverse port 25 adapted to be brought into registration to a greater or less extent with the passage 18 for controlling the inlet of auxiliary air or decarbonizing fluid.
One of the most essential features is the provision of automatic priming means, which feature is accomplished by forming the body 10 with a basin, well or recess 26 located at the lower edge of the opening 12 in such position as to catch and retain condensed gasoline flowing back down the walls of the manifold subsequent to the stopping of the motor.
In order that the valve device may be operated from the drivers seat, I provide a rod or the like indicated at 27 connected with the handle 22, slidable through a suitable opening in the dash and equipped with an operating button or head 28.
. In the use, it will be apparent that the device is of course mounted between the flanges E and F of the intake manifold and carburetor respectively and held by the studs Gr. When the valve plug 21 is in such position that the port 25 is out of registration with the passage 18, the device is entirely inactive in so far as the admission of air or decarboni zing fluid is concerned;
Whenever it is desired to admit auxiliary air for the purpose of thinning the mixture, it is merely necessary that the operator grasp the head or button 28 and'pull upon,
the rod 27 for turning the plug 21 and bringing the port therein more or less into registration with the passage 18. When this is done the suction of the engine pistons drawing in the. fuel mixture will also draw in air through the passage 18, which air is dis charged across the screen 13 at a slightly backward angle and it is evident that this air will spread out over the entire screen and impinge forcibly against the current or stream of mixture, resulting in the breaking up of the globules and a more intimate commingling of the vapor or spray with the .air so that the mixture will be rendered more combustible and eflicient while at the same time economizing in the fuel consumption.
\Vhenever it is desired to introduce a decarbonizing fluid, the valve may be opened and the liquid poured into the cup 17 from which it will flow naturally through the passage 18 into the opening 12 and be carried along by the mixture into the engine cylinders.
The recess or well 26 acts to collect and retain gasoline which condenses on the intake manifold wall subsequent to stopping of the motor and as there is practically no opportunity for evaporation, this condensed liquid will remain in this well or recess immedi-v ately adjacent the bottom edge of the screen in the most advantageous position for effecting priming and insuring easy starting of the motor even in very cold weather.
If for any reason the accumulated supply within the recess 26 should be insufficient, or
in case the motor has been standing idle for S5 a sufliciently long time that this accumulation might have evaporated, the valve may be opened and gasoline poured into the cup 17 so as to refill the well or recess and effect priming. I From the foregoing description and a study of the drawing it will be readily apparent that I have thus provided a very simply constructed device which may be installed without involving any chan es in the 05 motor and which is capable of ful lling all of the specified functions in a highly satisfactory and easy manner. In actual practice I have discovered that the device is of great advantage not only in permitting the introduction of auxiliary air and decarbonizing liquids but also'in making starting an extremely simple matter regardless of how stiff and cold the motor may be, the priming supply accumulating automatically and being always in proper position ready for instant service.
While I have shown and described a preferred embodiment of the invention, it will be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart "from the spirit of the invention or the scope of the subjoined claim.
I claim In a device of the character described, a body adapted for interposition between the outlet of a carburetor and the inlet of a manifold, the body having an opening establishing communication between the carburetor and manifold a wire-screen covering said opening, an extension on the top of the body having a passage leading into said opening at the top thereof, a cup at the upper end of the extension, and a rotary con- 1 trol valve intersecting the passage and operable to regulate communication therethrou h, the lower or outlet end of the passage eing inclined at a backward angle with respect to the direction of flow of fuel mixture through the opening whereby air entering through the passage will spread out and pass over the entire screen, the body being formed with a collecting well at the lower edge of the openingfor the accumuand running lation of gasoline condensm subsequent to back down the manifold wa stopping of the motor, whereby the accumu-' lation within the well will serve as priming means.
In testimony whereof I hereunto affix my signature.
GEORGE W. MERGER.
