' CARBURETER OR THE LIKE.

Specification of Letters Patent.

Application filed J um: 12, 1911.

To all whom it may concern Be it known that l, WALTER C. WEsT- AWAY, a citizen of the United States, residing at Belvidere, in the county of Boone and State of Illinois, have invented certain new and useful Improvements in Carbureters or the like, of which the following is a de scription.

, My invention belongs to that general class of devices known as carbureters, designed to suitably and efliciently co-mingle fluids, as for example air and a suitable hydro-carbon, and has amon its objects the production of a simple, efli cient, durable and satisfactory device of the kind described foruse wherever found applicable.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described,

and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts, Figure 1 is a sectional view of my device taken substantially on line 1, 1 of Fig. 2. Fig. 2 is a sectional view taken sub stantially on line 2, 2 of Fi 1. Fig. 3 is a perspective view of the va ve member 49. Fig. 4 is a sectional view taken substantially on line 4, 4 of Fig. 1. Fig. 5 is a sectional view taken substantially on line 55 of Fig. 1. Fig. 6 is a sectional view taken substantially on line 6, 6 of Fig. 1. Fig. 7 is a side elevation of the upper portion of my device, looking substantially from the line 7, 7 of Fig. 2. Fig. 8 is a sectional view of the valve member, and Fig. 9 is a sectional view of the same, taken substantially on line 9, 9 of Fig. 8. I

Referrin to the drawings, in which my preferred term of device is shown, the casing comprises a shell 12 provided with a suitable base 5 and top 12, the same being secured thereto in any suitable manner. Any suitable arrangement for securing the parts together may be employed. As shown, the base is secured to the top by a coupling 4, which enga es the base, and a suitable extension on t e casing part1. The base may be of any suitable form, as shown it is provided with a plurality of outlets for connection with an engine having a plurality of cylinders. Referring particularly to Fig. 1. the base is extended in the form of a pipe 6 provided with outlets 8, the interior of the pipe being connected or open to the interior of the casing by an opening 7, so that the mixture may pass through the opening to the outlets 8 through suitable pipes to the engine. Where the device is used on a single cylinder engine, one of the outlets 8 may be closed, or the base may be made with only one outlet. This, however, is a matter of detail, as the base may be formed with any desired number of outlets. The top 12 is provided with one or more openings 13 for the admission of air or the like, and with a suitable hydro-carbon or fluid inlet, as will be more fully explained in the operation of the device.

Arranged within the casing is a member which preferably comprises shells 15 and 16 separated by a partition 20. The partition 20 is arranged to serve as a valve within the casing, the same being provided with a face 17 arranged to cooperate with a suitable valve seat 11 within the casing. The shells l5 and 16 are preferably flanged on the exterior as at 18 and 19, so as to contact with the inner walls of the casin at those points, chambers 27 and 33 bein ormed between the shells 15 and 16 anf the casing. The shell 15 is provided with a plurality of openings 22 therein, the same being preferably in the form of narrow slots, and the part 16 on the opposite side of the partition is also provided with a plurality of similar openings 23, it being understood that the arrangement of the openings ma be such as desired. It will be seen that t e preferred construction comprises a valve member provided with a tubular extension on each side thereof, each extension bein provided with openings therethrough. T e partition or valve 20 is preferably extended as at 24 and 21 (see Fig. 8) and provided with an opening 25 therethrough, through which is arranged a valve stem 28 that controls the admission of oil or hydro-carbon to the casing, as hereafter described, The valve is normally maintained upon its seat 11 by a resilient member 26, or its equivalent, which bears against the base 5 and a ainst the lower side of the partition or V vs 20, the

1 1, and

resilient member being maintained against displacement by the extended rim or ring 24 upon the under side of the valve, and a suitable recess in the base (see Fig. 1)

As is most clearly shown in Fig. 1, 28 is a valve stem provided with a needle valve end 32, which controls the admission of oil to the interior of the device through a duct 35. The stem 28 is resiliently maintained against its seat 34 (see Fig. 5) by a resilient member 31, or its equivalent, 30 being a baille arranged on the valve stem, and 23 a nut or its equivalent for maintaining the valve in position and limiting its movement. The duct 35 extends to the face of the top the oil or hydro-carbon may be admitted thereto and the supply controlled in any desired or preferred manner. shown, 1 extend the top 1 1, as shown at 38, the top being provided with a duct 36 and 37 from the fgce 4A of the top to the ex-' terior. At the end of the part 38 1 show a cap 41 and part 39, 422 being suitable paclring material. The fuel or oil supply pipe is connected to the extension 38, so the oil passes through the duct 42 and ducts 37 and 36 to the face 14. The admission of oil, however, is controlled by'a suitable valve 49, or its equivalent, preferably arranged to seat upon the face 44:, The valve 19 is provided with a slot or groove 50 therein, which is preferably at an angle, or has one face or side angling, so that as the same is moved upon the face 4-4, it gradually opens or closes the duct 35 and controls the flow of fluid therethrough. The valve 49 may be controlled and maintained upon its seat in any suitable manner. As shown, it is arranged within a casing 15, secured upon the face 14: of the top 12 by screws 16, or their e uivalents, the casing 45 being provided with a chamber 47 therein, in which the valve is arranged, the casing being arranged to guide the valve in its movement. The valve is maintained tightly upon its seat or the face 1 1 by a part 51, which is maintained in close contact therewith by a resilient member 52, or its equivalent, arranged in the extended part- 53 of the valve casing 45. A simple construction for operating the valve comprises a lever 56 above the mounted or the extended part 58 of the casing, and provided with teeth 57, arranged to mesh withteeth 55 on the valve, so that as the lever 56 is turned about its pivot, the valve member 49 is moved longitudinally in the desired direction.

Any suitable means may be employed for controlling the admission of air to the interior of the casing; As shown, a very simple construction is a plate 61 arranged upon the end or top of the part 2, and provided with openings 62 therethrough (see Fig. 1). Any suitable means may be employed for maintaining the plate against ro-- tation, as for example, a pin 60 (see Fig. 1) 1s provided for the purpose. The top 12 is preferably extended as at 63 to the lower side of the plate 61. Arranged above the plate 61 is a plate 64, provided with openings 65 therethrough (see Fig. 4) the openings shown being of such size as to register with the openings 62 when the top plate 6 is moved to its extreme position. The plate 64 is arranged to be moved so that when rotated about the extended part 63, the openings 62 and 65 will not register exactly, so that the openings for the air may be diminished as desired. Any suitable means may bev employed for operating the plate 64, or maintaining the same in the desired position. As shown, the plate 64: is extended through one of the air inlets 13, as at 66, and provided with a pin 63 and a resilient member 69, the pin 68 being adapted to engage suitable notches 71 in the top part, normally maintaining the plate 6 1 against the movement. As shown, the pin 68 is provided with a knob for convenience in operating, and the part 66 is extended as at 67, and may be in the form of a pointer arranged to co'clperate with suitable graduations 72, to indicate the position of the plate.

Any suitable means may be employed for opening the valve 15-16, if it is desired to prime the carbureter. As shown, a pin 7 1 is provided, which extends through the top 12 to the flange 19, and is resiliently maintained up by a spring 76, a collar 75 being provided for limiting its movement. At the end of the pin 74 is a top 77 for convenience in operating.

The operation of the device may be briefly described as follows: Assuming that the carbureter is suitably connected to the fuel supply pipe and to the engine, the valves being substantially in the position shown. At each impulse of the engine in drawing in a fresh charge, the valve 20 and extensions 15, 16 are drawn downward, thereby drawing down the valve 32 and permitting the oil to enter the interior of the casing, the air being drawn in through the openings 13, 65 and 62. The oil or hydro-carbon is conducted to the duct 35, controlled by the valve 32, through the ducts 40, 37 and 36 and chamber 50 in the valve 19. The oil drops upon the baflle or deflector 30, where it is met by the air and the oil and air passing through the openings 23 into the chamber 33, and as the valve is open, by the valve seat 11 between the valve face 17 and the seat and into the chamber 27, thence through the openings 22 to the interior of the shell or tubular extension 15 through the outlet 7 and outlets 8 to the engine cylinders. As soon as the charge is admitted the resilient member 26 shuts the valve 20, thereby shutting the valve 32, preventing the oil from entering the casing through the duct 35. The amount of oil admitted may be increased or decreased by operating the lever or throttle 56, thereby exposing more or less of the duct 35 for the admission of oil. The air may be controlled by shifting the position of the end 64. As the oil and air strike the baffle and pass through the openings 23, they are co-mingled and are further coniingled as they pass between the valve face 17 and its seat 11, and are further co-mingled in passing through the openings 22, so

- that when they reach the outlet 7 they are ltd properly co mingled to give a perfectsmixture.

As is obvious, when the engine is not running the valve 20 is positioned upon its seat 11 and the duct is closed by the valve 32, so that the carburetor is not flooded. If it is necessary to prime the carburetor, the button 77 may e depressed, thereby operating the pin 74, which pin resting upon the flange or top 19 of the shell 16, depresses the valve 20 and thereby opens the valve 32, so that the hydro carbon or oil is admitted to the carbureter. 1

Having thus described my invent-ion, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention,

hence I do not wish to be understood as limiting myself to the exact form, gonstruction or combination of parts herein shown and described, or uses mentioned.
