A. M. WALTER GAS ENGINE AUXILIARY i 7 I. m H 1 Z Q JWII' WITNESSES: IN V EN ATTORNEYS.
rates ASHER M. HALTER, OF EASTON, PENNSYLVANIA,
GAS-ENGINE AUXILIARY.
Application filed. September 29, 1822.
To aZZ whom it may concern Be it known that l, Asnnn iii. YVALTER, a citizen of the United States, residing at Easton, county of Northampton, and State of Pennsylvania, have invented certain new and useful improvements in Gas-Engine Auxiliaries, whereof the following is a specification, reference being had to the accompanying drawings.
This invention relates to auxiliaries for internal combustion eng' ics, and the object thereof is to provide a device for permitting the introduction of air into the cylinder during operation in automatically controllable quantities and in such manner as to accomplish certain advantages among which arethe increase of power by the more ellicient consumption of the fuel. reduction in carbon deposits, economy the cons'iurption of oil and fuel, and other advantages of the invention is more fully disclosed.
Another object of the invention is to pro-- vide a device for the purpose set forth which is adapted to be inserted in the opening of an internal combustion engine usually provided for the priming cup, and embodying a priming cup in its assembly so as to secure the advantage. mentioned above while retaining the use of a priming device.
These and other objects are accomplished by what I now regard as the preferred embodiment of my invention from among other forms and arrangements embraced within the spirit of the invention and the scope of the appended claims.
in the accompanying drawings, Fig. I is a view in section of a combined priming and auxiliary air feeding device constructed in accordance with the present invention.
Fig. H is a view in transverse section taken on the line ll-ll of the preceding figure; and
Fig. HT is a view in section taken on the line IH-IH of Fig. I.
The invention embodies in its essentials a priming valve of the type generally employed in engines for motor vehicles, and an air feeding device associated therewith.
The air feeding device comprises a fourway casting or cross-coupling consisting of the longitudinal member 11 having the bore 12 and the transverse member 13 provided with the intersecting bore 14. The ends of the longitudinal member are threaded internally at 15 a threaded nipple 16 ap- Serial No. 591,245.
propriate for introduction into the opening of an engine cylinder being inserted in one of said threaded ends.
The customary priming cup employed in motor vehicle engines may be removed and the present device substituted. To that end the portion 16 should be threaded to a cor-- responding pitch so as to be received in gas-- tight engagement. The priming device of conventional type is indicated generally at 17 and includes a reduced and threaded end 18 which is inserted in the threaded end 15 of the cross coupling. The priming device is formed at. its opposite end with a cup member 19 draining into a longitudinal bore 20 which communicates with the bore 14, a valve 21 being fitted into the device and adapted to control the passage of fluid through the bore 20 and to effect a closure.
The auxili 7 air feeding arrangement comprises a pair of plugs 22 each of which is reduced at one end forming a shoulder threaded as at 23 for introduction into its corresponding end of the cross member 13 of the four-way casting. A copper gasket may be introduced between said shoulder of a n d the plug and the end of the cross-coupling to maize a gas-tight joint. The exposed end of the plug is angularly formed to facilitate the application of a wrench. Each plug is formed with a continuous bore 2% or channel extending throughout and disposed horizontally during use of the device communicating at their inner ends with the interior of the cross coupling and at their opposite ends with the atmosphere by means of slightly reduced aperture 25. The bore and aperture may be conveniently formed by drilling the plug, inserting the drill into the reduced end first and drilling until the point of the drill begins to break through the opposite end of the plug, whereupon the drill is removed. This operation results in the formation of a slight bevel at the juncture of the bore and aperture for cooperation with a spherical valve 26 which is subsequently inserted into the bore. The spherical valve should be of a diameter to loosely fit the bore but to effect a checking closure by contact with the surface of the bevel portion thus closing the aperture under the influence of pressure within the device. For the purpose of limiting movement of the valve in the bore a pin 27 is extended across the bore and is preferably spaced very closely to the valve so that when the valve is closed in tight engagement against its seat its distance irom the pin will be in the neighborhood of 1/64; of an inch.
In the operation of thedevice when properly associated With an internal combustion engine in the manner stated, the-rise in pressure created during each compression stroke being communicated to the interior of 'the cross-coupling will effect a closure or seating of-the ball valves so as to prevent the escape of pressure, but during an intake stroke the ball valves will be unseatcd permitting the entrance of small quantities of air past the valves and ultimately into the engine cylinder. The quantity of fresh air permitted to'enter is very small but suiticient to insure the production 01" the advantages noted, such as the complete combustion of the fuelnnda reduction'in carboi'i deposition.
It 'Wlllb apparent thatrif the degree of vacuum in the engine cylinderduring an intake stroke is .light the valves \villbe unseated only slightly admitting only a-quantity of air sufficient to accomplish the desired results, as when theiengine is operating under an openthrottle. lvhen the engine intake isheavy the valves Will be unseated to a greater extent"permitting the entrance of a-inaximum amount of air. It Will be noted thatthe arrangement in no Way interferes with the introduction of priming fluid into the cylinder when necessary, and witliout :necessitating the removal of'the air feeding device, "The-aise of springs is avoided as the ball valves are controlledsolely by the iinfluence of engine compression and suction.
Having thus described any invention, I claim: r
,1. In auxiliary :air-zfeeding and priming :device for internal combustion engines,
the combination :of a multiple-Way couplingzforconnection into an engine cylinder, a :plurality of zplugs fitted into said coupling :having horizontal channels and orifices for iatlmitting air tO'lillBtOylllIdBI, and
ball valves adapted by limitedmovement to open and close the aforesaid orifices under the influence of engine compression and suction respectively.
' 2. A priming and auxiliary air feed (levicefor internal combustion engines comprising a four-Way coupling one terminal WhGIBOflS adapted to serve as a priming cup, a plug inserted in each of a pair of axially opposed terminals, each said plug having a bore with a reduced inlet orifice, a ball valve in each channel for controlling its respective inlet orifice, and means insuring a limited movement at all times of said ball valve under the influence of varyingengine compression and suction.
3. Ina combined priming and auxiliary air feeding device for internal combustion engines, the combination of a four-way coupler having aligning horizontal bores, a plug removably inserted in eachsaid horizontal bore and havinga reduced inlet orifice, a ball valve in each:ch'anneladapted to seat against the reduced inlet orificeyand means insuring a very limited 'movementnt all times of said ball valves under the influence of engine compression andsu'ction.
4. In a combined priming and auxiliary air feeding device for internal combustion engines, the combination of a four-Way coupler having opposed horizontal channels, a plug removalaly inserted in each said cl1anneland having a reduced inlct orifice, a ball valve in each channel adapted to seat against the reduced inlet, and -a transverse pin ineach plug adapted to limit the movement'at all times of its associated ball valve under the influence of engine compression and suction.
In testimony'whereof, I have hereunto signed-my name at Easton, Pennsylvania, this twenty-fifth day :of September, 1922.
