KALIAZOO, MICHIGAN', KALAKAZOG, MICHIGAN.
Canam-seran..
To 'all whom it may concern.'
Vlle it known that We, WILLIAM SHAKE- slimme, Jr., and WILLIAM Scrum), citizens of the UnitedStates, residing at Kalamazoo,
Michigan, have invented certain new and useful Improvements in Carbureters, of which the followingr is a speeicat-ion.
rlhis invention relates to improvements in carbureters.
The main objects of this invention are: First, to provide an improved carbureter in which the proper relative proportions of the fuel and air are automatically maintained throughout varying running conditions of the engine.
Second, to provide an improved 'throttle vcontrolled carbureter in which the relative proportions of fuel and air are automatically maintained throughout the scope of the throttle adjustment.
rl`hird, to provide in a carburetor anim-- proved valve mechanism which is not likely to get out of repair or adjustment in use nd one which is very simple in its operation.
Further objects, structural details,
andobjects relating to will definitely appear from the detailed description to follow.
We accomplish the objects of our invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.
A structure which is a preferred embodiment of our invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

parts throughout the ing chamber 3 and delivery passage which end by the is controlled at its delivery s. own being of throttle valve 4, the valve the well known butterfly type having an arm 5 to which the operating connections are made. The passage in the body member 2 constitutes the supply orair inlet passageands provided with a hot air inlet 6 and the cold air inlet 7 both' controlledl As the details of` our present invendescribed herein. provided with a by ,the rotaryv al've 8. this valve form no part of tion they are not further The body member 2 is fuel reservoir 9 having an inlet connection 10 controlled by the valve 11. This'valve is controlled by the float l2 carried by the `lloat lever' 13 which is pivoted at 14 and adapted to engage the stem of the valve 11. The reservoir is provided with a removable cover plate and with a draw off cock 16 through which any sediment collected inthe reservoir may reservoir. I
The body sections able screws 17. The body section is provided with perforated ears 18 by means ofv which the carbureter may be attached to the manifold as is common ininternal combustion engine practice her 21s provided with an The body memannular shoulderseat constituting the mixing chamber 3. lVithin the body is an automatically actuated member 20, the member being supported so that it is actuated by thesuction withinthe carbureter. This member 2() is yadapted to seat on the valve seat 19 and constitutes an air valve for the mixing chamber 3.` The member 2() is chambered to provide acarbureting chamber 21 which has a plurality of delivery openings 22 delivering into thefmixing chamber 3.
The tubular nozzle member into the ca rbureting chamber andl is connected to the reservoir b v the passage 24. rlhe fuel nozzle 25 is threaded into the member 23 for be drawn oli by flushingl the-n are1connected by suit- 23 projects adjustment therein, the nozzle being pron0 g A l 1,234,227
` ing its longitudinal passage with the nozzle member 83.
. At its upper end the fuel nozzle 26 has a fuel valve seat Q9. The carbureting chamber valve zEllis annular to embrace the upper end of' the fuel nozzle and has a conical por- 1b tion 31 courting with the upper end of the fired nozale member 23 and a sleeve-like portion 32 slidably embracing the nozzle member. This sleeve-like portion has air inlet Openings 3U opening into the air inlet passage oi the carbureter below the mixing chamber valve. The fuel valve 34 is of the needle type, its point coacting with the fuel nozzle as shown in Fig. III.
` The valve member is provided with a 20 Astem-like plunger 35 coacting with the dash pt'dwhich is disposed in the mixing chamber or on the inner side of the valve membersofthat it is subject to the variations in the air pressure or degree of vacuum in the '25 mixing chamber. It is found quite satisfactory in practice to permit thev air to escape from the dash-pot around the plunger. 7The plunger 35 serves as a guide stemv for the valve member 20. The plunger 35 is Ahollow 3o to receive the stem of the fuel valve,.and is' provided with an adjusting screw 37 for the fuel valve, the fuel valve being held against its adjusting screw by means of the coiled spring, 38.
35 'It is intended that the fuel valve shall be adjusted to its `proper place when the car bureter is assembled and it is not intended. for adjustment by the user as that is not necessary. Such operating adjustment as is `4o required is effected by the adjustment of the fuel nozzle.
The dash-pot for the valve member 20 prevents chattering and fluttering of the f valves.
By locating the daslrpot of the suction actuated member in the mixing chamber it is subject to all variations of air pressure therein due to throttle or engine control and the running conditions of the engine, which renders the suction actuated member very sensitive and quick acting and quickly responsive to the throttle control and the running conditions of the engine.
Were the dash-pot subject at all times to atmospheric air pressure or to any air press'ure other than that of the mixing chamber, there would be, under ordinary running conditions, a constant variation between such air pressure and that acting upon the suction actuated member thereby preventing evenness in the movement or action of the suction actuated member under the varying suctions or degrees of vacuum in the mixing chamber. and where a liquid dash-pot is provided the same variations occur. When,
however, the dash-pot is in the mixing chamber and subject to the variations of air pres' sure therein these conditions are overcome and the actuated member is very sensitive and quick in its action;
A; further advantage o arranging the dash-pot in the mixing chamber is that it is easy to locate it so that it constitutes an effective guide for the suction actuated member, Further, it is entirely inclosed and cannot be distorted by carelessness when the carbureter is assembled in an automobile or from" accidental blows or the like while in use.
A still further advantage is that where the dash-pot is open to atmospheric air it is likely to draw in dust ,and dirt and become clogged thereby. When located in the mixing chamber, any dust that enters the mixing chamber with the incoming air is not likely to passto the dash-pot, but is, owing to the velocity of the air, drawn past the dash-pot into the manifold.
A, still further advantage is that when positioned Within the mixing chamber it is Asubject to the vapors therein so that in practice it is effectively lubricated. This accomplishes a double purpose,-that of preventing wear and frictioztand, further, the moisture forms a suitable packing so that a free sliding ,5t may be had between the parts without objectionable leakage past the plunger, In fact, practical use of the structure has demonstrated that the action is very superior to that in structures in which the dash-pot is subject to atmospheric air or to structures in which the dash-pot is of thev oil or liquid type.
With the parts thus arranged we provide a structure in which the relative proportions of air and fuel are automatically maintained throughout varying running conditions `of vas the engine and throughout the throttle ad: y
justment, the carbureter being controlled for normal operation entirely by the engine throttle.
Our present improvements are an adaptation and in some respects an 4improvement upon the structure illustrated and described in Letters Patent No. 1107713, issued to us August 18, 1914, and that shown in our Letters Patent, No. 1,183,125, issued to usMay 1G, 1916.
.-f. lVe have illustrated and described our present improvements in the form in which we have embodied the same in practice. We have not illustrated or described various modifications which we contemplate as ive believe the disclosure made will enable those' skilled in the art to embody our improvements as conditions may dictate. We de sire, howevento be understimd as claiming our improvements specilically in the form, illustrated as well as broadly within the scope of the appended claims.
