Specification of Letters Patent.
Patented Feb. 23, 1915..
Application filed February 27, 1911. Serial Ito. 611,064.
To all whom it may concern:
Be it known that we, WILLIAM SHAKES- PEARE, Jr, and WILLIAM SoHMID, citizens of the United States, residing at Kalamazoo, Michigan, have invented certain new and useful Improvements in Carburetors, of which the following is a specification.
This invention relates to improvements in carburetors.
The main objects of this invention are: First, to provide an improved carburetor, in which the proper relative proportions. of the fuel and air are maintained. Second, to
provide an improved carburetor, in which the quantity of the fuel. delivered may be accurately controlled. Third, to provide an improved carburetor, in which the air or throttle valve and the fuel valve are simultaneously operated. Fourth, to provide in the carbureter an improved structure which is not likely to get out of adjustment or repair in use. Fifth, to provide in an improved carburetor a valve mechanism which can be adjusted for convenient attachment to the operating connections. I
Further objects, and objects relating to structural details, 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 invention, in which:
Figure I is a side view of a structure embodying the features our invention. Fig. T1 is a central longitudinal section through the structure shown in Fig. I. Fig. III is a horizontal section taken on a line correspending to line of Fig. ll. Fig. TV is a detail horizontal section taken on a line corresponding to line i-A- of Fig. II. Fig.
V is an inverted perspective view of the body member 16, the fuel valve and air valve being shown in operative relation thereto. Fig. V1 is a detail perspective view of the throttle or air valve. Fig. VIT is an inverted perspective view of the valve memher 19. Fig. VIII is a detail section corresponding to Fig. IV of a slightly modified structure.
In the drawing, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking ii". the direction of the little arrows at the ends of the section lines.
Referring to the drawing, the carburetor body 1 is providedwith an air passage 2, adapted for connection to the engine cylinder, the connections not being here illustrated as they will be readily understood. In the bottom of the air passage 2- is a cavity 3. This cavity is partially closed by a blocklike member t, having groove-like passages 5 therein. This is for convenience in manufacture as the passages, 5 might be otherwise formed. These passages form a. by pass passage around the throttle valve as will appear as the description proceeds. This by pass passage is connected to the fuel reser voir 6, by means of the passage 7.
The fuel feed reservoir is connected to a suitable source of supply by the pipe'8, the delivery passage 9 of which is controlled by valve 10, the valve being controlled by the float 11. The details of this valve and its connection to the float, form no part of the present invention and are therefore not described with further detail herein. The fuel reservoir is formed of a cylindrical body portion 6, preferably of glass, as shown, the base portion 12 and disk-like top 13, the body 1 being shouldered to reeelve the top,
' all the parts being clamped together by the coupling member 14, as shown in detail in Fig. 11. This construction greatly facilitates manufacture and makes it possible to finish the parts as may be desired.
The body for convenience in manufacturing and assembling of partsis provided with an opening 15 opposite the fuel passage. This opening is closed by the body member 16, the member being detachably secured as by means of the screws 17. The fuel valve 18 is of the needle type and seats into the upper end of the part 7 of the fuel feed passage, it being shown in Fig. II, in its completely closed or seated position. The valve 18 is threaded into the valve member 19, which in turn threaded for adjustment into the body member 16. A spring washer 20 is disposed between the valve member 19 and the body member 16 to take up any slack or lost motion in the threads. The valve member 19 is adapted to receive the valve lever 21, which is ad justably secured upon the upper end there.
of by meansof the screw the head of the "lever lie ing split and provided with ears 23 through which the screw is ,arran ed.
Mounted on the valve above t, e valve lever is an index disk 24 as shown in Fig. III, to facilitate the accurate adjustment of the valve, the disk being rotatably secured to the valve which is flattened at its upper end as shown in Fig. II. v p I A clamping nut 25 is provided for locking the valve in its adjusted position in the valve member 19'; The valve member 19 is provided with steps 26 and 27 which coact with the stop 28 on the body member 16,
The stop 26 is adapted to locate the valve in its open position and the stop locates it in its; closed position. The stop 27 is made adjustable so as to determine the closed position of the control valve as shown in. Fifg.' VI. .The valve29 is rovided with a hub portion 30 through whic the valve 18 is arranged. The valve 29 is operatively connected with the valve member 19, by means of the lugs 30 on the valve which engage notches 31 in the lower end of the valve member. This loose connection for the fuel and throttle valves permits the adjustment of the throttle valve and its longitudinal movement, while the throttle valve has a rotary or oscillating movement.
It will be observed that the passage 5 forms a by-pass or auxiliary ail; passage around the air valve. This, when the an passage is closed, or partially closed, causes a direct stream of air to pass through passage 5, breaking up or atomizing the fuel very effectively. This fuel can be very accurately controlled by the adjustment of the valves. By providing this by-pass or auxiliary air passage around the air or throttle valve in communication with the fuel supply, the increased suction caused by closing or artially closing the throttle acts direct y on the fuel to effectively break up or atomiz e the same.
For convenience in manufacturing parts, the body member 16 is provided with o posed side members 32 which are located in recesses 33 in the body.
The valve 29 is located between these parts 32. By forming the body with the opening 15 and mounting the valves on the closure 16, the parts may be readily assembled or disassembled and are simple in structure.
In order to maintain the relative proportion of the air and fuel throughout the move ment of the control valve 29, we form vertical curved grooves or channels 32 in the faces of the side members 32 of-the body member 16. For some engines, these are not needed, and the said members 32 are then formed with flat faces, as shown in the modified structure of Fig. VIII. These grooves 32 can be readily milled into the body member 16, or it can be left with flat faces, as shown in Fig. VIII.
The fuel reservoir is provided with a drain valve which consists of a nipple-like valve casing 34, having a valve seat 35 at its inner end, its outer end.being threaded to receive the Valve stem 36 of the valve 37. Thevalve stem is'provided with a passage 38 having lateral inlets 39 to the rear of the valve. To open the valve it is only necessary to screw it out sufliciently to draw the valve slightly from its seat and the liquid will as around the valve into the passage'of t e stem.
We have illustrated and described our improvements in a simple embodiment thereof.
We are aware that various changes or modifications in structural details are possible, but as such modifications or'changes will no doubt be readily understood by those skilled in the art to which this invention relates, we have not attempted to illustrate or describe the same herein.
Having thus described our invention what we claim as new and desire to secure by Letters Patent is:
1. In a carbureter, the combination of a valve actuating member having threaded en gagement with itssupport; a fuel valve threaded through said valve actuating member; an index disk for said fuel valve mounted to be adjusted therewith; a fixed stop; coacting stops on said valve member, one of which is adjustable; and a throttle valve loosely mounted on said fuel valve for longitudinal movement thereon and operatively connected with said valve actuating member.
