To all 'L0 hom t may Concern.'

Be it known that I, ERNEs'r F. SAYLOR, a citizen of the United States, residing'in the city of Ilwaco, county of Pacic, and State of Washington, have invented certain newV and useful Improvements in Carbureters, of which the following is a specification.

My invention relates to carbureters, an more particularly to certain new and novel improvements therein, whereby I am able to make a variety of adjustments of the various parts thereof, and thereby to get a better regulation and greater efficiency therefrom.

Among the salient objects of my invention are,-to provide in a carbureter an air inlet valve, an oil inlet valve, and a throttle valve, with means for effecting a simultaneous and uniform movement thereof, and with means for adjusting said valves relative to each other and relative to the ports which they control, whereby I amable to most eifectively regulate the air and oil inlet passage-ways to the carbureter, and the pas'- sage-way leading from the carbureter to the cylinders, so as to secure the best mixture of air and oil for the engine; to provide in a carbureter of the character referred to, means whereby, with a single controlling or operating member, I am able, not only to control the movement ofY said valves, but with such means I am able by various adjustments of the connections to cause one or two of said valves to move faster or slower than the other, or others, in its, opening or closing operation, and thereby to open or close `either-before or after the other, or others, as desired; to provide a carbureter case or body in two or more parts or sections, adjustable relative to each other, whereby to `conveniently adapt'said carbureter for connection with the engine cylinders at various angles; and, in general, to provide a new and improved carbureter of the character referred to which will be practical, eiicient and convenient to adjust and manipulate.

In order that others may thoroughly understand my invention, I have shown in the accompanying sheets .of .drawing Vone practical embodiment thereof, which I willA now describe:

Fig. 8 is a top plan view similar to Fig. 3, showing a different connection for operating the oil or needle valve, and y Fig. 9 is a fragmentary, vertical sectional view showing a slight modification in the connection for operating the needle valve.

Referring now more in detail to the drawtaken ving, the carbureter here shown for the purpose of illustration, comprises a cylindrical body composedy of the lower section A, an upper section B, and a top, or cover, C. Referring to Figs. l and 2, the lower portion of the section A has an annular water jacket A1, an annular air chamber A?, with a cylinmember A1, having a plurality of inlet ports A1 therein, with a main airinlet A5 at one side, leading through the water jacket A1 to the annular air chamber A2. Rotatably mounted within the cylindrical wall member A3, is a cylindrical airinlet valve A, having a plurality of air-inlet ports A7, adapted to be moved into and out of registery with the ports A4 in said cylindrical wall member A3. lSaid air-inlet valve is provided with a central operating shaft AS, upon` the upper end of which is mounted a laterally projecting operating arm A9. Said air inlet valve A, is open at its upper end so that air passing in through the inlet A1, the ports A1 and A7 will pass upwardly into a mixing chamber A1o in the upper portion of the section A. Formed in the outer part of said upper section is an annular oil chamber A11, having mounted therein a float A12, of cork or other suitable float material, supported at one side by an arm A13, piv-A otally mounted at A14, in an extension chamber A15, on the side of the body, and adapted to automatically move an oil inlet valve A1, which controls the inow of oil to the annular oil chamber A11. The annular oil cev -nism whereby said vided on its top surface with an oil puddle or needle valve cup, A10, having a centralV port A20, opening down into said passageway A18, whereby the oil from the annular oil chamber A11 rises through said passageway A18, and the port A20 dle A10.

The upper section B of said carbureter also comprises an outer annular water jacket B1, an annular chamber B2, with a cylindrical wall member B1, having ports B1 therethrough. The lower end of said cylindrical wall member B3, is provided with supporting arms B1", for supporting a lower bearing plate member B0, above said puddle, A10, substantially in the manner indicated. Rotatably mounted within said cylindrical wall member B3, is a cylindrical throttle valve member B7, having ports B8, therein, adapted to be moved into' and out of register with the `ports B1 in said cylindrical wall member B3, said cylindrical throttle valve member B7 V'being closed at its'upper end and provided with a bearing sleeve B0, and being open at its lower end.

The body section B, fits upon and over the annular oil chamber A11, with an annular holding flange B10, itting down into the chamber A10, to hold said parts together, and whereby to make the part or section B, adjustable circumferentially upon said lower section A, to bring the main outlet B13 to a desired angle for connection to the engine.

Mounted through the sleeve B"J of the cylindrical throttle valve member B7, is an operating sleeve B11, `which eXtends through said throttle valve member and has a bearing at its lower end in the plate B0, just above the oil puddle A10. Said operating sleeve B11 is rigidly connected by means of an arm B12, extending out around said plate B6, and the puddle member A17, to the arm yA0, upon the upper end of the shaftA8. Said operating sleeve B11, turns within the sleeve B2, yof the cylindrical valve member B7 so that when the said sleeve member B11 isoscillated about its own axis it operates to turn the air inlet valve A0 below. A needle valve B14 extends through the sleeve B11, and has its lower end tapered to vfit into the port A20 for controlling the flow of the oil from the annular oil chamber through the passageway A18, and thence through said port A20 to the puddle A10, where it is exposed tothe air passing upwardly through the chamber A10.

I will now describe the operating mechaair inlet valve A0, said throttle valve B7, and said needle valve B14,

are manipulated to control and regulate the passageof air up through the carbureter and around the oil puddle A10. Mounted a passage-way A18, and pro-y into the pud- ,a part of the throttle valve B7, is provided and lower the same by reason of the threaded upon the upper bodysection B, isa plate Y C, through an opening in the center of which the sleeve B9 works, and through this sleeve B0, the operating sleeve B11, and the needle valve B11 project. A iiXed arm C2, is mounted upon plate C', and projects upwardly and inwardly over the center of said plate, and constitutes a bearing support for the upper end of the sleeve B11, and the needle valve B11. To this end. said arm C2 is provided at its upper end with a threaded hublilre portion within which turns an externally threaded smaller hub member C3, having a short arm C1, and secured to the upper end ofthe needle valve B14,lso that as said arm C1 is turned, it is raised or lowered by reason of the threads in the hub of the fixed arm C2, thus also raising and lowering the needle valve B14 out of and `into the oil inlet port A20, to the oil puddle A10, to control the inflow of the oil. The upper end of the sleeve B11 simply has a holding `bearing in the under side of the fixed arm C2,

The upper end of the sleeve B0, formed as with an operating arm C0, having an adjustinent slot C0 in its outer end. The upper end of the sleeve B11 is also provided with a similar 'operatingarm C7, having an adjustment slot C0 in its outer end.

A main operating arm D is extended into the upper casing or cover C, and has a pivotal bearing at D', around the upper portion of the hub of the Xed arm C2. The short arm C1, upon the upper end of the needle valve B11, has a loose pin connection with the arm D, as at D2, whereby as said arm D is moved sidewise, short arm C4 is also moved to turn said needle valve, and to raise connection through the varm C2. A pair of toggle links D-D1, connect the arm D, as

at D5, to the outer end of the arm G7, being adjustablyconnected therewith in theslot j C6. A pair of toggle links D0-D7, also con- 110 nect saidA mainlever D, at D5, with the outer end of the arm Cbeing adjustably connected therewith in the slot C8. A spring memv ber C0, attached tothe upturned portion of the arm D, bears outwardly at its opposite ends against thelinks Dand D3, Vas shown in Fig. Y Y

'Two bearing cam members E1-E2, are pivotally mounted upon the plate C in position to bear against the toggle links at their joints, which may be provided with anti-friction rings D0*D8 in the manner indicated. Said bearing cams have curved bearing surfaces and can be adjusted inwardly or outwardly, by means of thumb screws, EL- 4, so as to be concentric with the pivotal bearing of the operating mechanism, or so as to be eccentric to said pivotal bearing, thus causing said toggle links at their joints to be moved according to the admoved, but if said cam operating mechanism,

bearing members E1 justment of the cam and E2. If the cam bearing members E and E2 are adjusted surfaces stand concentric with the center of the needle valve, which is the center of the operating mechanism, then the parts of the toggle links will maintain their relative angular positions as the operating lever D is bearing members E1 that their lbearing to the center of the but are eccentric thereto, then as said main operating lever D is moved in one direction or the other, said toggle links will tend to straighten, or move together, as the case may be, in addition to their general movement. This is because the joints in said toggle links bearing against the cam bearing members E1E2, will be moved inwardly, or permitted to move outwardly, by reason of the position of the cam bearing members. This operates to move the arms C1 and C5 in opposite directions, either uniformly with the movement of the lever D, as when the cam bearing members are concentrically adjusted, or faster or slower than said operating lever D, depending upon the adjustment of said cam bearing members. Stops Da and De, may be provided to limit the eXtreme movements of the operating lever D, as indicated in Fig. 3.

In Fig. 3 the main operating lever D, has a direct, positive connection with the needle valve through the short arm C4, and the air inlet valve and the throttle valve have a variable connection with said operating lever D by reason of the toggle links, arms C1 and 5, and the cams E1 and E2. In Fig. 8, I have connected the main operating lever D, directly to the throttle valve, and have turned the short arm C4 around a quarter turn, and connected it to the arm C, whereby the air inlet valve, operated by the arm 5, and the needle valve, operated by the short arm C1, which is directly connected to the arm Ce, have the variable connections, while the throttle valve has a direct connection, with said operating arm D.

In Fig. 9, I have shown a slight change in the connection for operating the needle valve. Instead of turning the threaded hub portion C3, and the needle valve B11, upon which it is mounted, by means of the operating lever D, as in Figs. 1 and 3, I have provided the operating lever D, at its connected end, with a threaded hub, adapted to turn on the smaller threaded hub C3, upon the needle valve B11, whereby to lift said needle valve without turning it, together with the short arm C1 and its holding pin D2, which has a holding, adjustable connection with the upper end of the fixed arm C2, which is made as clearly indicated in said Fig. 9.

The water supply, for the water jackets A'-B, is connected thereto, as at 2-2, and

and E2 are adjusted so faces are not concentric so that their bearing Y said water jackets are connected to communicate with each other by means of a bypass pipe at 3-3.

' The extension A15, on the side of the carbureter body is provided with a `removable plug 4c, to afford access to the interior thereof, for adjusting the oil inlet valve A16, which is operated by the float A12.

The operation of Vthe'invention may be briefly described as follows Assuming that the parts are assembled as illustrated in Figs. 1 to 4 inclusive, the air inlet valve A6, the needle valve B11, and the throttle valve B1, will all be approximately half open, as illustrated in Fig. 4, in which the ports A", of the air-inlet valve A6, are shown to be about half'in register with the ports A1, of the cylindrical wall member A3. In this position the vair passes into the can bureter through the main inlet opening A5, through the ports A1 and A7, up through the chamber A1", around the oil puddle A19, and upwardly into the throttle member B1, and thence through the throttle B13 to the engine. The arm C5, which operates the throttle valve B7, and the arm C7, which operates the air-inlet valve A6, through the operating tubularmember B11, can be so adjustably connected to the toggle links, D4 and D7, by reason of the slots C6 and C8, therein, that they can be opened and closed together, or a limited variation can be made through the connections to said links, whereby one or the other will'k open in advance of the other.

If it is desired that one or the other of said arms, C7 and C5, should be moved faster or slower than the other, this may be accomplished by adjusting the thumb screws Eor E1, .so as to move the cam bearing members E1 or E2 inwardly, or outwardly, as hereinbefore referred to. For example, if thumb screw E1, is turned so as to move the cam member E2 inwardly, it will tend to straighten the toggle links D3 and D1 and thereby move the arm C7, which operates to turn the air-'nlet valve A slightly, andas the bearing surface of this cam member E2 would be more or less eccentric to the pivotal axis of the arm C2, and the operating lever D, this would operate to vary the movement of the arm C7, relative to the movement of the operating lever D, the difference being compensated for through the relative movements of the toggle links D3 and D1. rIYhus' I am able, through the connections from the air inlet valve A, and the throttle valve B7,`and the needle valve B11, to the main operating lever D, to operate said airlnlet valve A, and the throttle valve B7, and the needle valve B14, together at the same speed, or at different speeds, or to adjust their Connections so that one will commence to open before the others, if desired, and thus to regulate the amount of air passing through the carbureter, whereby to secure the best mixture of the air with the oil, or gasolene.

If it is desired that the variable movements and adjustments should be made possible in the needle `valve .and the air-inlet valve, yinsteadof the throttle -valve and the air-inlet valve, Ican connect the main operating-lever 4D direct to the throttle valve, as indicated in Fig. 8, and can connect the needle valve armC4, and gthe air-inlet valve '07, yto the vtoggle links, Dit and D7, as indi- Vleave va thin disk-like space there between, past the edges of which the air passes in its upward movement, picking up thethin film of oil as it passes. There 1s also a more effectlve suction action, so to speak, acting to .draw the oil upinto the oil puddle, for the reason that the oil ismoreeii'ectively picked up and carried from around the edgeof the narrow space rbetween the member BG, and the puddle A19, than it would be-'from an open uncovered puddle of oil.

Attention is also called to the fact that the ports controlling the inlet of the air into the carbureter, and the ports which control the outlet therefrom, or the suction action, so called, applied to the carbureter at the outlet B13, by the action of the engine, must be regulated as to theirrelative areas, in order to get the best results. The more of the vacuum effect created in the carbureter will, of course, tend to causev the oil to rise therein, and'to be sucked up, so to speak, by the air which is rushed through the carbureter, under the suction action caused by the movement of the pistons in the engine cylinders.

I am aware that changes can be made in the embodiment in my invention as shown for purpose of illustration without departing from the spirit thereof, and I do not, therefore, limit my invention to the particular showing here made, except as I may be limited by the hereto appended claims.
