GARBURETER.

Specification of Letters Patent. Patented N 30, 1915 Application filed november 3, 1914. Serial No. 870,148.

To all whom it may concern:

Be it known that I, LESTER G. POND, a citizen of the United States, residing=at Seekonk, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement. in Carbureters, of which the following is a specification.

This invention relates to certain new and useful improvements in carbureters, and the primary object thereof is to provide improved means for effecting carburization by the employement of a series of independent gasolene outlets which present the gasolene to the incoming air, combined with improved valve mechanism which gradually lncreases or decreases the number of the outlets exposed to the air.

Further, the invention aims to provide improved valve mechanism which not only gradually controls the number of outlets exposed to the air, but which also, following movement thereof to a predetermined extent cuts ofl' all of the outlets from the air.

Still further, the invention aims to provide'means whereby the valve mechanism may be adjusted so as to vary the closing of the outlet ports by movement of the mechanism, that is to say to enable the mechanism to be adjusted so that either a short or a long movement of the same will efl'ect closing of the outlets.

Further, the invention resides in certain details of construction and combination of parts hereinafter more fully described.

In the drawings Figure 1 is a side elevation of the invention showing same in position in an automobile. the line 2-2 of Fig. 3. Fig. 3 is a front elevation. Fig. 4 is a section on the line 4-4 of Fig. 2. Fig. 5 is a section on the line 5-5 of Fig. 2. Fig. 6 is a detail perspective view of a part of the rotary valve mechanism. Fig. 7 is a similar View of the other part of the rotary valve mechanism. Fig. 8 is a similar view of the gasolene feed plate having the gasolene channels, and Fig.

9 is a similar view of the top plate which is secured to the plate of Fig. 8, so as to close the upper portions of the channels of the latter.

In proceeding in accordance with the present invention a casing is employed which Fig. 2 is a section on said chamber, the opening 7 being common and feeding gasolene to a series of transverse channels 8 which are formed in the upper face of plate 6 and extend through the front edge of said plate. A plate 9 is superimposed on the plate 7 and has a beveled front edge 10, the plate being adjustable transversely of the plate 6 by means of the screw and slot connections 1l12.' The plate 9 acts to close the upper portions of the channels 8 so that the gasolene from chamber 4 will, when vaporized, be drawn through the channels 8.

The casing has an extension 13 bored to receive a rotary valve part 14, the other valve part 15 being received within the part 14. The part 14 has a longitudinal slot 16 the longitudinal walls of which slot are straight. The part 15 of the valve has a longitudinal slot 17, the wall 18of which slot is inclined so that as the valve is rotated within the part 14, the wall 18 will gradually expose or cut-off a number of the channels or outlets 8 to or from contact with the air drawn into the carbureter through the intake 19 by the engine movements, as shown in Fig. 2. As shown in Fig. 5, the inner ends of

parts

14 and 15 are open so that the air and the gasolene will pass through said open ends and be mixed together in their passage through.

part 15 and through the pipe 21 which leads to the manifold 22. The usual throttle valve 23 is located Within pipe 21 and is connected to an arm 25, to which latter a link 24 is pivoted,'the link being pivoted to in working position, the valve parts are adjusted as follows: The valve part 14 is first moved in such position by the arm 20 as to cause the slot 16 to be fully open to the intake 19'; the valve part 15 is then rotated by the rod 26 to bring the inclined wall 18 in proper position for the slow running of the motor without moving the load, as indicated in broken lines 18 m Fig. 2; and the arm 25 is then connected to the rod 26 to properly locate the throttle valve. After the. adjustment and connection ofthe parts, as above described, the rod 26 is connected in such well known manner to .the wheel and foot pedal, that the rotation of the valve 15 may be effected therefrom. The motor is now started and as the valve part 15 has been set to permit-the running of the same at low speed, the motor will continue to do so until the valve part 15 is changed to increase the speed. The valve part is now adjusted for normal high speed. This adjustment is effected by the rotation of the valve part 14 by the arm 20, so as to bring one edge of the slot 16 over the point of the inclinedslot 17, as shown in Fig. 2.

It will be apparent that depending upon the rotation of the valve part 15 more or less gasolene outlets are presented in a straight line to the incoming air and as these outlets are very small a fog-like vapor is produced by the contact of the air with the gasolene. The structure is extremely simple in adjustment and all parts can be. readily re moved for the purpose of cleaning.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a carbureter, a fuel chamber, a pair 1 of adjustable superimposed plates having a series of independent gasolene outlets formed therebetween communicating with the chamber, a pair of telescopic valves having longitudinal slots which communicate with each of the outlets, one of the valves being formed to completely cut-ofl' the outlets, and means to enable independent operation of the valves.

j 2. In a carbureter, a fuel chamber, a member having a series of independent gasolene outlets which latter communicate with the chamber, and a pair of adjustable and independently rotatable valves one of which gradually exposes or cuts off the incoming air to the. outlets and the other of which is adapted to completely cut off all of the outlets from the incoming air or to regulate the amount of air which can come in contact with the entire number of outlets.

3. In a carbureter, a horizontal main fuel chamber having a feed chamber "communieating therewith and arranged at one side thereof and being open at its top, amember on the top of said feed chamber and having a series of independent channels on its top face and an opening which communicates with the feed chamber interior and with the channels, a plate adjustable on said member and closing the tops of the channels, and a rotary cylindrical valve arranged at one side of the feed chamber so that the channels are substantially tangential to the valve.

4. In a carbureter, a fuel chamber, cylindrical air regulating means at one side of and spaced from the chamber, and horizontal adjustable means arranged over the space between the chamber and air regulating means and substantially tangential to the last named means to divide the fuel into a series of separate streams and to cause the latter to communicate with theair.

5. In a carbureter, a fuel chamber having an outlet, and a pair of telescopic rotatable valves arranged substantially tangential to said outlet and each having a longitudinal slot, one of the valves having a straight edge parallel to the axis thereof and the other valve having a straight edge inclined with respect to the axis thereof.

6. In a carbureter, a fuel chamber having an outlet, and means arranged ubstantially tangential to said outlet to control the outlet having two straight edges one of which is inclined and the other parallel with respect to the axis of the means.

7. In a carbureter, a fuel chamber having a straight edged outlet, and means arranged substantially tangential to said outlet to control the outlet having two straight edges one of which is inclined and the other parallel with respect to the axis of the means, the parallel edge being adapted to contact with the straight edged outlet to close the latter.

8. In a carbureter, a fuel chamber having an outlet, and a pair of relatively adjustable superimposed plates having a series of independent fuel outlets formed therebetween, which outlets communicate with the chamber outlet.

' 9. In a carbureter, a fuel chamber having a fuel outlet, and a pair of valves arranged substantially tangential to the outlet and being independently adjustable and movable for, controlling the outlet, one of said valves having a slot providing a wall which when engaged with the fuel outlet completely closes the latter. v

10. In a carbureter, a fuel chamber having an outlet, an adjustable valve arranged at one side of the chamber in spaced relation In testimony whereof I have signed my thereto and having'an upwardlg facing slot name to this specification in the presence of slot.
