Application filed June 15, 1916. Serial No. 103,835.

To all whom t may concern Be it known that I, HUGH C. GILLIAM, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have 1 nvented a new and Improved Auxiliary Air- Supply Device for Internal-Combustion Engines, of which the following is a full, clear, and exact description.

This invention relates to controlling devices for internal combustion engines and particularly to an improved device f or supplying air thereto, and has for an ob]ect the provision of means which will supply air 1n any desired' quantity to the engine, the same being connected to the manifold between the carbureter and engine so as to dilute the mixture before its entrance into the engine..

Another object in view is to provlde a valve structure connected to the intake manifold of an engine, the same being arranged to be quickly and easily adjusted for supplying different quantities of air as the same may be needed.

A still further object in view is to provide a valve which is simple and strong in 1ts construction and which is made of a minimum number of parts so as to reduce to a minimum any chance of getting out of order.

In the accompanying .drawing z-Figure 1 is a fragmentary view of the engine and steering wheel of an automobile, an embodiment of the invention being shown in connection therewith. Fig. 2 is a plan view of the valve embodying the invention. Fig. 3 is a section through Fig. 2 on line 3- 3. Fig. 4 is a section through Fig. 3 on line Referring to the accompanying drawing by numerals, 1 indicates an internal .combustion engine of any desired kind, which is supplied with an explosive mixture by the carbureter 2, the mixture passing through a manifold pipe 3 to the various branches 4. The detail construction of the manifold, the engine and the carbureter form no part of the present invention. Connected to the pipe 3 in any suitable manner 1s an a1r plpe or tube 5 which is preferably of suiiicient length to extend to near the steering wheel 6 of the automobile. A valve 7 is connected with the post 8 of wheel 6 by any means, as for instance, a clamping band 9, so that the valve willbe at a convenient point for operation by the driver. The intention is to supply an auxiliary or extra supply of air to the cylinders of the engine whenever deslred. By experiments it has been found that after an engine has been running for some time and has attained such speed as to heat the cylinders, asupply of fresh air into the manifold between the carburcter and the cylinders will result in producing a better explosion and, consequently, the production of more power. If the extra speed produced by the additional power is not desired the fuel supply may be reduced so that the explosive mixture from the carbureter 2 will not be in such great quantities.

The detail construction of the valve 7 is shown in Figs. 2, 3 and 4, in which it will be observed that the valve is formed of a minimum number of parts and the parts are so arranged as not to readily get out of order. The valve 7 is provided with an upper section 10 and a lower section 11, the lower section being provided with arms 12 to which the band 9 is connected when the valve is applied. The sections 10 and 11 are screwed together, as shown in Fig. 3, so as to provide a chamber 13 into which air is admitted on the turning of the, disk valve 14. The disk valve 14 is provided with an annular valve seat 15 bearing against the upper face of the end 16 of section 10, said upper face being preferably ground to produce a reasonably smooth surface which coacts with the valve seat 15 for producing a substantially airtight joint. The disk valve 14 is provided with an overlapping depending annular flange 17 which slidingly fits against the outer surface of the section 10, said flange being cut away for approximately half a circle, as shown in Fig. 4, whereby shoulders 18 and 19 areY produced, said shoulders being designed to strike against the pointer 20 which has a finger 21 overlapping the disk valve 14, as shown in Fig. 2, for indicating the relative position of said valve. The pointer 20 is secured to the section 10 by any suitable means and acts in the double capacity of a pointer, as shown in Fig. 2, and as a stop, as shown more particularly in Fig. 4. The top of section 10 is provided with an arc-shaped slot 22 which remains fixed or stationary when the section is screwed into place, as shown in Fig. 3.

The dist' valve 14 is provided with a number of' apertures 23 which are of diHerent sizes, gradually increasing from one end of the series of apertures to the other, each aperture being numbered as shown in Fig. 2 so that the operator may see how-much air is being admitted. For instance, when the engine is first started the disk valve 14 is positioned as shown in Fig. 2, namely, closed, and is maintained in this position until the engine has become heated and is moving at an appreciable speed. The disk valve 14 is then moved until, for instance, the first aperture 23 registers with the slot 22. This will allow a certain quantity of air to enter the engine without passing through the carbureter. The disk valve 14 is later moved to expose the next aperture, and so on, until asuicientquantity of air is being admitted. In order that the valve seat 15 of the disk valve 14 may fit more or less tightly against the top 16 of section 10 a resilient washer 24 is provided which is maintained under tension by a nut 25, said nut engaging a threaded extension 26 projecting from the top 16. Also section 11 is provided with a tubular extension 27 roughened on the-exterior or threaded on the -inside for receiving one end of the hose or pipe 5, said connection being protected by a thimble or sleeve 28 held in place on section 11 by friction or any other suitable way.

The particular construction and arrangement shown and described act very much in the nature of an accelerator, though the device does not force into or inject in anynvay any additional gas. The admission of an extra supply of air by the valve 7 causes a better combustion and causes a more complete utilization of the gases already supplied by the carbureter 2, whereby to get the same speed a less quantity of fuel may be supplied by said carbureter. The valve 7 has been described as being connected to the steering post 8 near wheel 6, but it is evident that the same may be arranged adjacent the seat of the driver or at any other desired place without departing from the spirit of the invention.

What I claim is:

1. In a valve structure for admitting air to the manifold of an explosive engine, a pair of sections removably connected together, the lower section being formed with an extension for receiving a connecting hose and the upper section being formed with an arc-shaped slot, a disk valve arranged on said upper section provided with a plurality of' openings and an annular bead forming a valve seat, said openings extending through said valve seat, and means for holding said valve seat against said upper section.

2. In a valve of the character described, an upper section, a lower section threaded to said upper section. means for connecting a hose to said lower section, said upper section being formed with an arc-shaped slot and with a ground upper face, a disk valve member provided with a projecting annular bead formed with a ground seat fitting on said upper section, said seat covering said slot, said disk valve member being provided with an opening extending through said valve seat, said disk valve member being rotatable so that said openings may be brought into registry with said slot and moved out of registry, and means for limiting the rotary movement of said disk valve A member.

3. In a valve of the character described, a hollow body provided with an arc-shaped opening in the top, a disk valve member fitting on said body, said disk valve member being formed with a depending flange having a notch extending for approximately one-half of its circumference whereby two shoulders are produced, a series of openings adapted to be brought into registry with said slot, said openings increasing in size from one end of the series to the other, a seat, a combined pointer and stop connected with'said body to strike against said shoulders for limiting the rotary movement of said disk valve member, and resilient means for-pressing said disk valve member against said bod y HUGH C. GILLIAM.
