Specification of Letters Patent. Patented Feb. 21, 1.911.
Application led February 8, 1909. Serial No. 476,619.
zTo all whom tt may concern:
Be it known that I, ALEXANDER WINTON, a citizen of the United States, .residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Carbureters, of which the following is a specification, referencebeing had therein to the accompanying drawing.
This invention relates to improvements in carburetor-s, andpertains to a type of carbu- 'reter in which the gasolene feed or flow is automatically controlled by 'the amount or volunio of explosive mixture (which is now commonly termed gas which is permitto the engine cylinder or cylinders.
This invention is adapted to be used either with t-he butterliy type of throttle here shown, or with that type shown in my prior Patents #626,120, May 30th,1899; #626,121,
-May 30th, 1899, and #635,218, October 17th,
1899, in which the explosive inlet valve or valves act as a throttle to regulate and control the flow ot' gas to the engine. cylinder, and in turn controls the speed and power of the engine.
This present improvement comprises means I for -controlling the How of gasolene according to the volume of gas passing to the engine cylinder,vwhich is not connected with the throttle element, though it is controlled thereby, as will fully appear hereinafter.
In the accompanying drawings, Figure 1, a vert'cal section of a carbureter embodying my invention, taken centrally through the air passage. Fig. 2, is a vertical section of the same, taken at right angles to Fig. 1. In carrying out the present invention, I preferably provide an air passage A which has a vertically-extending portion 1 at its A lower end; and ahorizontally-extending portion 2 at its upper end. The upper end is suitably connected with a passage 3, and this passage is connected in any suitable manner with the engine cylinder, which is not here shown. Placed in the passage 3 is a suitable throttle 4, and closing the lower end of the passage A is an air-actuated valve 5. Projecting dowinvardly from the lower end of the air passage 3 is an arm oi' arms 6, and the lower ends of these arms carry a suitable casting 7, which forms the top of a removable dasli-pot 8. The upper end of this dashpot is internally screw-threaded, and the l jecting `cap or casting 7 is externally screw-threaded to mesh with each other, as shown at 9. The air passes'or flows'V into the passage-way 1 between the arms 6 and through the opening 10 in the lower end of the. passage-Way A, which, as before'stated, is controlled by the air or pressure actuated valve 5.
A vertical web 11 passes across the horizontal portion 2 'of the air passage A, and this web is provided with a vertical gasolene conduit 12, the -lower end of whichis in com munication with a gasolene chamber 13 through the means of a conduit 14. The upper portion of they conduit 12 is 'provided with a gasolene exit-15 through which the gasolene is sucked into the horizontal portion of the air passage. A needle-valve 16 is vertically arranged in this web 11, and is adapted to seat therein at the point 17 for the purpose of controlling the liow of the gasolene through tl'ie'conduit- I2 to the outlet 15. This needle-valve 16 projects through and beyond the passage-way and has its prostem 18 externally screw-threaded and receiving an` arm 19, which arm is carried by the upper-'projecting end 20 of a rod or stein 20. The rod or stem 20 also passes through the web 11, and is attached toa'nd I' moved with and by the valve 5, the att-achment being as here shown by a pin 21. This rod or stem passes through the valve 5, through the dash-pot cap 7, and has its lower end 22 extending centrally into the dash-pot. Connected adjustably to the lower end 22 is a piston 23 which moves freely within the dash-pot, and this piston may be provided with a plurality of openings 2/1 to permit it to move through the liquid 25 placed therein, which liquid is preferably glycerin. A suitable springl26 serves to normally press downward upon the' stem 20, and as here shown, this spring is in the form of a spiral and has its lower end engaging the piston 23 and its upper end abutting against the under side of the dash-pot cap 7. A suitable vadjustable nut 27 is placed upon the projecting stem end 22 and below the piston, whereby the piston may be adjusted and the tension of the spring 28 regulated, which in turn controls the pressure of the valve 5 upon its seat, and thereby determines the amount of air pressure valve, in the manner plained. adapted necessary to lift the slightly open,
.tle controls 'throttle slightl projection 29, is an adjustable screw 30, by means of which the needle-valve 16 and the valve 5 may be lslightly lifted froml their seats 4for the purpose of setting them at a` mitted to flow to the engine, and thereby controls the volume of air which asses to and through theair passage A. 1th the open for minimum speed, suicient air wi l flow by the valve 5 without materially lifting it, and this air flowing past the gasolene exit 15 draws or sucks the gasolene through this passage into 'the horizontnl portion 2, and the air 'having the gasolene mixed with. it, then becomes what is usually termed in automobile parlance, as gas. As the throttle 4 is open wide, the
volume of air passing to and through the air passage A is` correspondingly increased,-
and also its velocity, 'which will cause the valve 5 to-be lifted and the needle-valve. 16 correspondingly lifted, to permit 'the proper proportion of gasolene toflow to properly carburet the volume of air. stood, of .course, that the needle-valve is so shaped that the volume of gasolene permitted to flow through the conduit 12 to the exit 15 is-inthe proper proportion to the amount of air which-passes taper 31 of 'the the valve 5 at its various elevations or dis- ,y
tances from its seat, which will insure the proper carburetion of the air forthe best y the volume of air passing passage, and this in turn is controlled by and most economical results in the engine. In this manner, the volumeof air and the volume of gasolene are automatically controlled in the proper relative proportion by .through the air the throttle 4.
As. previously stated, this invention' is adapted to be used with any form of throttling element, either that of the butterfly form here shown, orA of that form shown in y my prior patents herein'referred to. Themain feature of the present improvement being the proportionate control of the gasolene supply to the volume of air that is passing through to be earbureted, and formed into what is commonly referred to as gas.
The object of the dash-pot 8 is to prevent the fluttering of the air valve 5 and the gasolene valve 16, so that their movements will The gasolene chamber 13, from which the gasolene Hows to the conduits 12 and 14, is provided with any suitable form of device which creates aten ency to- It is under-A let, a gasolene' conduit having passage, the gasolene and azz-54,874
for maintainingv the gasolene therein atla' predetermined level, so that the gasolene in turn is maintained in the conduit 12 at ay level corresponding to the level in the chamber 13. As here shown,this is accomplished through themedium of a float 32 which is connected to valve 34 willv close the gasolene opening 35 to the said chamber 13 when the gasolene in the chamber has reached the predetermined level. This level is laced at the proper point in relation to t e outlet passage 15, and the level here shown is not intended'- to be the exact level to be used inthe practical operation of the carbureter but only `approximately the redetermined level. i
By removing e cup 8 access may be had to the adjusting nut 23 for the purpose of regulating the tension of the spring 26, and
a cup-shaped cap 36 is placed over the upper end of the needle-valve 16 and the stem 20. The screw 30 holding the stem 20 and Vvalve 5 at the adjusted position, the needlevalve may be adjustcd'by turning it in respect to its seat 17, after which the taper 31 will take 4care of the proportionate feed of the gasolene in accordance to the amountl of air that is to be carbureted.
Having thus described this invention, what is claimed and desired to be secured byy Letters Patent, is 4 4 l 1. -A carbureter provided .with an air passage having an air inlet and a'mixture outthe air passage, means maintaining an oil an exit within the stem 33 of a valve 34. This level in the conduit below said exit, and be'` tween its ends, a throttling element located beyond the gasolene exit, a gasolene valve controlling the flow of gasolene through said gasolene exit, and a valve at the air passage inlet and opened, in proportion to the volume of air passing through the air air inlet valves connected and opening and 'closing together and means normally holding said valves slightly open, for the purpose described.
