Specification of Letters Patent.
Patented May 7, 1907.
Application filed July 2 6, 1906. Serial No. 327.868.
To all whom it ntay concern:
Be it known that 1, J AMES W. ASIIBAUGH, a citizen of the United States, residing at Bremen, in the county of Fairfield and State of Ohio, have invented certain new and useful Improvements in Valves; and I do declare the following to be a full, clear, and we act description of the invention, such as will enable others skilied in the art to which it appertains to make and use the same.
My invention relates to improvements in gas valves, and more particularly to one adapted tor use in controlling and regulating the supply of gas and air to a burner of any description.
The object of the invention is to provide a combined air and gas mixing valve 01 simple, practical and e'liicient construction, which is espe iially adapted to use upon gas stoves or heaters which burn natural gas.
With the above and other objects in view, the invention consists in the construction, combination, and arrangement of parts hereinaiter described and claimed.
In the accompanying drawings,Figure 1 is a side elevation of my improved valve; Fig. 2 is a vertical longitudinal sectional view through the same; Fig. 3 is a vertical transverse sectional view, taken on the plane indicated by the line 33 in Fig. 2 Fig. 4 is a side elevation of the valve proper and its stem; Fig. 5 is a perspective view of the adjustable cam, which actuates the valve; Fig. 6 is a top plan view of a modified form of valve; Fig. 7 is a vertical longitudinal sectional view through the same; Fig. 8 is a vertical transverse sectional view, t-aken on the plane indicated by the line 88 in Fig. 7; and Figs. 9 and 10 are detail views of the valve proper and its actuating stem.
Referring more particularly to Figs. 1 to 5, inclusive, of the drawings, the numeral 1 denotes the body or casing of my improved valve, which, as shown, is tubular in form and has one of its ends screw-threaded to re ceive a gas supply pipe. Carried by the opposite end of the body or casing 1 is a mixer casing 2, which is in the form of a double cone made of two half sections secured together at their large ends by a lap joint, as clearly shown in Fig. 2. "he casing has at one end an annularfiange 3, adapted to be securely clamped by a set-screw t upon a burner or the like. The outer cone portion of this mixer body or easing 2 is cut away upon its lower half, as
shown at 5, and this opening is adapted to be covered and uncovered by the semi-cone shaped portion 6 of a rotary air valve or shutter 7, the latter having at its small end an annular collar or ring 8 to engage and rotate upon the body 1, and upon its large end a notched annular flange or ring 9, which is bent over the central portion of the mixer 2 and is adapted to turn thereon. Upon the shutter 11 is provided a finger-piece or knob 10 to facilitate turning it to open and close the opening 5 in the mixer Upon the outer face of the portion 6 of the rotary shutter 7 is an adjustable cam 11, by means of which the motion of said shutter is imparted to the gas valve 12 within the body or casing. This cam 11 is in the form of a semi-circularshaped, spirally-arranged plate, which has its inner edge engaged with a notch or seat 1.3 in the outer end of the stem 14 of the valve 12. This cam plate 11 has one of its ends fixed upon one end of a semicircular attaching plate 15, which latter is adjustably secured by screws 16 upon the shutter 7; and its opposite end is adjustablyconnected to the opposite end of the attaching plate 15 by means of a screw-stud 17. The latter projects from the plate 15 and through an aperture in the free end of the cam plate 11, and upon said screw-stud on opposite sides of the cam plate, are adjustable nuts 19. By adjusting the latter upon the screw-studs, the angular or spiral disposition of the cam plate 11 may be regulated to control the opening and closing of the valve, as will be presently explained.
The gas valve 12 is in the form of a cylindrical body mounted for longitudinal sliding movement in the bore of the body or casing 1, and having in its sides longitudinal grooves or passages 20, and upon its outer end a cone shaped portion 21, which moves toward and from a similar-shaped valve seat 22, formed in the inner endiof a screw-plug 23, which closes one end of the casing 1.. T he valve 12 is forced upon its seat by a coil-spring 24, arranged in the casing 1. between the inner end of said valve and a shoulder 25, provided in the bore of said casing. The stem 14 of the valve 12 is of substantially U-shape and has its concentrically-disposed portion 26 arranged to slide in an aperture or opening 27, formed in the valve-seat or plug 23, said portion 26 having a longitudinal groove in one side thereof and being of suitable shape to permit of the escape of gas when the valve 12 is moved inwardly" against the tension of its spring 24.
The operation of this valve will be readily understood. Gas is admitted into the valve body or casing 24 through its threaded outer end or through any other suitable connection provided upon the same, and escapes through the grooves in the valve 12 and between said valve and its seat 23 when said valve is forced inwardly by its stem 14:. The latter, it will be seen, will be moved longitudinally whenever the shutter 7 upon the mixer 2 is rotated in the proper direction. When said shutter is turned or rotated to close the opening 5 in the mixer 2, the cam 11 will move vide for perfect combustion in the burner.
By changing the angular or spiral disposition of the cam plate 11, it will be seen that the opening of the valvewith respect to the opening of the shutter 7 may be regulated, as desired.
lhe modified form of the invention shown in Figs. 6 to 10, inclusive, of the drawings, is very similar to that of the one just described, the only difference being in the manner of operating the gas valve. The latter in this form of the invention has a straight stem 41, which corresponds to the portion 26 of the stem 14, and said valve is formed in its top with a longitudinallyextending \i-shaped groove or recess 28. The latter is adapted to receive the lower end of a bell-crank lever 29, which has at its angle a spherical enlarge ment 30, adapted to seat in a semi-spherical or concave depression 31 formed in the valve casing. Said spherical ei'llargement 30 is en gaged by the forked end of a spring 32, which retains it in its seat or socket 31, and is adjustably secured upon the casing by a screw 33. The outwardly-projecting end or arm 34 of the bell-crank 29 swings vertically in a slotted guide lug 35 upon the valve casing,
and projects into a cam-shaped or eccentricscre'wsonthenike 39 upon slotted brackets 40, carried by the shutter 7. This slotted cam plate corresponds to the cam plate of the valve first described, and serves to swing the bell-crank 29 as the shutter 7 is rotated. When said bell-crank is oscillated, it will be seen that its end in the recess 28 of the valve will move the latter to open or close the valve.
From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.
Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention, as defined by the appended claims.
Having thus described my invention, what I claim as new, and desire to secure by Letters-Patent, is,-
1. A device of the character described comprising a valve casing or body, and an endwise movable non-rotatable valve therein, a mixer, a rotary air shutter on said mixer, a cam on said air shutter presenting a surface inclined laterally to the plane of revolution of said shutter, and a connection between said cam and the valve to move the latter longitudinally when the air shutter is turned.
2. A device of the character described comprising a valve casing or body, an endwise movable non-rotatable valve therein, a
mixer, a rotary air shutter on said mixer, a cam on said air shutter presenting a surface inclined laterally to the plane of revolution of said shutter, means to adjust said cam, and a connection between said cam and the valve to move the latter longitudinally when the air shutter is turned.
3. A device of the character described cam and the valve to open the latter against the tension of its spring when the shutter is turned in one direction.
In testimony whereof I have hereunto set my hand in presence of two subscribing wit-
