ADJUSTABLE VALVE.

Application filed March 28, 1923. Serial Np. 628,269.

To all whom it may concem:

Be it known that 1, CHARLES H. Simmons, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Adjustable Valves, of which the, following is a specification.

My present invention concerns valves, especially those with adjustable characteristics, designed more particularly, but not restrictedly, for employment in connection with oil or other liquid fuel burners, whereby the fuel supply to the burner may be easily regulated without stopping the movement of the burner when the latter is of the rotary or revolving form.

A further aim of the invention is the provision of an appliance of this kind which assists or aids in preventing the burner and its pipe or conduit connections from becoming clogged or stopped up.

An additional purpose of the invention is to supply a structure having the functions specified which is simple in construction and hence ectnomical to produce and unlikely to become deranged, injured, or out of adj ustment during ordinary service.

To enable those skilled in this art to have a full and complete understanding of the invention and its various advantages in the accompanying drawings forming a part of this specification I have illustrated three embodiments of the invention and throughout the several views 0 thisdrawing like reference characters have been employed for the same parts.

In this drawing, i Figure 1 is a sectional or broken view of y a rotary oil burner equipped with one em 'bodiment of the-improved valve;

Figure 2 is a fragmentary, vertical section of a different embodiment of the invention; and

Figures 3 and 4 are'sections at right angles to one another of another form of valve structure, Figure ibeing a section on line 44 of Figure 3, the parts being viewed in the direction indicated by the arrows.

' The illustration in Figure 2 is on a somewhat larger scale than that shown in Figure 1 and the illustration in Figures 3 and 4 is on a still larger scale. 7

Referring first to the style of valve structure shown in Figure 1, it will be perceived construction actuated by that the burner construction comprises a base-plate 11 having an oil compartment or chamber 12 in which the fuel-oil, which also acts as a lubricant for the gearing, is main tallied at a substantially constant level by a float-controlled valve governing the delivery of the liquid through a supply pipe into the chamber. I

Such supply pipe connection 13 extends through one of the side walls of the chamber and inside of the latter it is fitted with a valve,14= of any suitable or appropriate a float 15 having alever connection 16 Wlth the valve, the lever being fulcrumed on theinside of the lar member has a burner 29 into which the oil or other fuel fed up the shaft is delivered and by means of which, due to its rapid rotation, the oil and air are roperly and thorou hly mixed or atomized.

he exact form and style of the rotary burner is immaterial so'far as the present invention is concerned, and, consequently, no

further description of-its structure or mode of operation is required.

Obviously, it is necessary or desirable to regulate or control the flow of liquid up through the upwardly extending or tapered passageof the shaft, and, accordingly, the

lower open end of the latter, through which it receives its fuel supply from the chamber, is equipped with a conical valve-seat 31 with which a correspondingly-shaped valve 32 coacts to open or close more or less the conv duit through the shaft.

Such valve is mounted on one end portion of an arm or lever 33 fulcrumed or pivoted on a part of the standard at 34:, the other end of the arm or lever having an upright rod 35 pivoted thereto at 36, such rod extending up through a hole in the cover-plate Thu-s the spring yieldingly tends to move the valve to closed position against its valveseat.

In order that the position of the valve 4 may be easily and readily adjusted, the upwardly protruding end of the vertical rod has a'collar 39 fastened to it, and beneath this, and bifurcated so as to straddle the rod, I employ a wedge 41 sliidable on the top of the cover-plate, the position of the wedge being controlled by a screw shaft 42 mounted in a threaded bearing 43 on the cover-plate and equipped with a turning handle 44, the' screw shaft being connected in any convenient manner to the wedge in such a way as to be capable of independent rotation on its own axis.

Hence .we'have an easily manipulated or adjustable valve to regulate the oil flow up the bore of the rapidly-revolving, hollow, vertically-disposed shaft, up which it is drawn by reason of the action of centrifugal force.

In this valve, one of these elements, the one with the port and the conical valve-seat, is adapted to revolve rapidly, while thecompanion member or valve pro er is relative y stationary, but yet adjusta le to govern the extent of valve openino" as may be required.

This is apparently a novel and simple construction permitting regulation or adjustment of the valve without stopping or interrupting therotation and operation of the revolving burner.

In Figure 2, I have shown a somewhat modified or different form of structure, wherein the conical valve 50 constitutes the upper end of a vertically-slidable shaft 51, guided in alined bearings 52 and 53,.both 1n members mounted on the baseplate of the oil chamber, and having rack teeth 54 cut in one side with which mesh the teeth of a gear 55 on a horizontal shaft 56 mounted in bearings 57 and 58 and extending but through a side wall of the oil chamber through a stuffing-box 59, the external end of the shaft having a turning wheel or handle 61 by means of which the position of the valveinay be regulated with facility.

In some cases, it is desirable to have the valve turn somewhat during its lengthwise adjustment and such a style of construction is depicted in Figures 3 and 4. r

In this device, the valve is formed on the upper end of an upright, screw-threaded shaft 71 in a threaded bearing 72 and having a reduced-diameter, lower, cylindrical part 73 received in another bearing 74 on the base-plate of the oil chamber, the complementary bearing 72 constituting part nesonoe of a bracket or support 75 mounted on such of which the gear may rotate the shaft, the

teeth of such gear being, in mesh with those of a gear 78 on a shaft 79 mounted and adjustable as is the shaft 56 of the other modification of the invention.

. Consequently, when shaft 7 9 is turned the valve will be adjusted by both a lon itudinal and rotative movement towar or from its revolving valve-seat.

In all these species the assage in the shaft tends to be kept f i'om' becoming clogged, the reason fOrxWhich action is not fully understood at the present time, but it may in part be due to the fact that it seems to be desirable, although not absolutely essential, to so mount the valve and permit sufficient play in its operating parts, that it may flutter or vibrate slightly during the action of the burner toward and from its revolving valve-seat.

Accordingly in some cases it is of advantage to mount the valve so that it may have the vibratory movement specified.

Those skilled in this art will readily understand that the invention is not limited and restricted to the precise and exact details of construction presented but that these may be modified within radical degree with out departure from the heart and essence of the invention and without the sacrifice of any of its substantial benefits and advanta es.
