devices and more particularly to such de-l vices as are adapted to be used in connection with liquid or gaseous fuel, and has for its principal object to provide a simplified form of such devices in which the feed of the fuel is automatically controlled and in which are safety devices for maintaining either a maximum or a minimum combustion.
Other objects will appear as the invention is vmore fully described in the following specication and shown in the accompanying drawings, in which- --Figure 1 is a central longitudinal sectional view of my device, with parts broken away. Fig. 2 is an enlarged fragmentary View, partly in section upon the line of y @bears the spring 27. To the lower end of the hollow castin Fig. 1, looking in the direction of the small arrows. i
Referring now more particularly to the drawings, the reference numerals 1 and 1a designate conducting pipes which are threaded, as shown, and to which are joined the hollow casting 2, by means of the unions 3 ,and 3a, and the fittings 4. Within the union 3 is the wall 5 in which is the bypass 6 which is normally closed by the valve 7 upon the upper end of the stem 8, the said stem being upwardly pressed by the spring 9 which is seated upon the plug 10 within the lower part of the said union. The said plug has the shoulder 11 which fits snugly against the lower edge of the union and which may be suitablypacked. The upper and lower ends of the said plug are threaded, as shown, and to its lower end is secured the cap 12, through which, and the said plug, slidably passes the stem 8 which extends downwardly and has its lower end threaded as shown, and to which`is fitted the correspondingly threaded block 13a. The hollow casting 2 is divided by the'wall 13 into the two chambers 14 and 15. Through the said wall is an opening to admit the lower end of the pipe 16, around which may be the packing 17. The pipe 16 extends upwardly and terminates within the baffle 18 in the cap19, which is secured to the upper end ofthe larger pipe 20, whose lower end is screwed into the hollow casting 2. In the extreme upper end of the cap 19 is screwed the shell 21 which is slotted through its top at 22 to form a jet or burner for the oil or other suchy fuel which, when the valve 7 is open, iiows through thelsupply pipe 1a, thence into the chamber .14 and upwardly through the small pipe 16 and finally emerges through the baffle plate 18 and ,mingles with the steam which comes 1n through the pipe 1 and forces upwardly through the large pipe 2Q. Through the wall 13 is the second opening to admit the valve plug 23. The chamber 15 may be shut o from the supply pipe 1 by means of the valve plug 24, in the same manner in which the oil supply may be cut off from the chambery 14 by its valve plug 7, as will be understood. The valve plug 24 has the stem 26 which is upwardly pressed by the spring 27 and which operates in the same manner as the spring 9 on the opposite side of the device, the plug 28 being screwed into the union 3a to close the same, and against which 2 is screwedl the hollow casting 29 wiich is ground to fit the lower casting 30 and the two castings are screwed together by means of the screw 3.1,
and between' the said castings 1s the diaphragm 31a. The casting- 30 is bored through at 32 to slidingly receive the stem 33 whose upper end 1s secured centrally to the said diaphragm. The casting 30 has the -downwardly extending legs 34 which join the disk 35, thev lower internal portion of which is threaded as shown, and to which is-secured the cylinder 36, in which slides the disk-37 which is upwardly urgedI by the spring 38. at 39 to slidingly receive the: stem 33, the lower end of which bears against the disk 37. The stem 33 is threaded for a purpose presently to be explained but the apertures 39 and 32 are smooth bored. Into the lower end of the cylinder 36 is screwed the closing cap 40,
through Awhich passes the screw 41, the opening through the said cap being scrw threaded to correspond to the threads of the screw, and against the upper end of the said screw bears the disk 42 which also slides within the cylinder 36. Along the lower side of the upper portion ofthe casting 30 are cut the racks 43. The lower end of the stemy 26 is screw threaded to the block 44 and project- The disk 35v is bored through Mesh'ing with the racks 43 are the pinion wheels 49 which are joined together in pairs bythe stems 50 which terminate at one of their ends in the angular stubs 51 so as to t a key and to be turned thereby. The stems 50 contact with the upper sides of the bars 46. -Pass' through thelegs 34 on one side of the device are the stems 52 which ter-v minate in the head blocks 52a, which normally bear against the bars 46 and are yieldingly held there by the springs 53, the upper sides of the said blocks constantly bearing against the lower sidey of the castingA 30, so as to slide freely. thereunder whenthe inner ends of the bars 46 are depressed below the plane of' the said blocks. One end of each of the springs 53 bears against one of the head blocks 52", and the opposite ends of the springs bear against one of the le s 34. The vcollar 47 is screw threaded to t the threaded portion of the stem 33, and may be adjusted up er down thereon by turning the collar, and fitted to the screw threaded portion of the stem 33 are also the jam nuts 55 and 56, the. latterl being upwardly pressed by the relatively light spring 57. The ipe 58 extends from the interior of the ho ow casting 29 to the steam supply pipe 1, Vso that when steam enters the sald supply ipe it descends into the hollow casting 29 alliove the diaphragm 31l and` forces the same downwardly against the acton'of the'spring 38 and thrusts the stem 33 and it attached collar 47 downwardly allowing he inner ends of the' bars 46 to correspondingly deseend.l
In the operation of the device the valve plugs 24 and 7 are first screwed downwardly through the block `44 and 13 respectively untilthe-"desired initial amounts of steam and oil respectively are permittedto pass through the pipes 1 and 1 into the chambersA 15 an 14 respectively,: the springs 9 and 27 tending always to force-the said valve plu upwardly. pinions 49 act as ulcrums for the'bars 46, and the collar'47 acts as an adjustable stop for the hooked ends of. the said bars. In the drawings the pinions 49 are shown equidistant from the stem 33, which allows the valve plugs 7 and 24 to stand away from their respective seats an equal distance, and permits the vsteam to low from the supply pipe 1 into the chamber 15 at the same rate as the oil flows from the pipe 1 into 'the chamber 14, which is not a ways desirable. It is obvious that as the forces-the dia- The stems l50 -which join t e' and 24 will be drawn u vwardly byA t eir respective springs 9 and'2 4'and that this upward movement of the-said plug will -b'e governed entirely by the positions o the pinions 49 and their stems 50 with respectto the stem 33. A If less oil than steam isv de'- sired to be fed all that is necessary is to rtate the right hand `pinion wheel 49 away from the stem 33, and i a greater feed of oil than steam is necessary the same pinion wheel is moved toward the stem 33. The pinion wheel upon the opposite side of the device may be moved in the same manner to a`ect the valve plu 24.- Thehead blocks 52, already describe have the effect of automatically governing the feed so that no less than a predetermined amount of either steam or oilv may be fed to the burner. The
downward movement of the hooked ends of the bars'46 necessary to free the head blocks 52a and allow them to sprin over the said bars, is, ofcourse, governed y the position of the collar 47 with respect to its stem 33. When the steam pressure becomeslsuilicient to cause the stem 33 and its collar-47 to move downwardly to permit the hooked ends of.
the bars 46 to drop' below thepath of thel head blocks 52, and the same spring out said jam nuts approach Ithe limit ofvtheir downward movement the light spring 57 is graduall compressed so as not to, cause" a too. sudden stoppage of' the parts, which might strip thel threads or cause other 'dama e. The tension ofthe large spring38 is a justable by means of thescrew 41', as will be understood.
While I have shown a particular form of 4 embodiment of my invention, 12am aware that many minor changes therein will readily suggest themselves to others skilled in the art, without departing from the spirit and scope of my invention. I do not therefore, desire to be limited to the exact form .shown and described, except. as limited in the appended claims.`
Having described my invention, what I claim as new -and desire toprotect by Letters Patent Y v 1. Thel combination with the steam and oil inlet valves and diaphragm of an oil burner, hf, a springstem centrally `connected *to the and .adapted to vibrate therewith, an Y' adjustable recessed collar upon said stem, levers connected with the" 'd valves 'and adaptedto hook over the iso annular edge formed by the said recess, racks fixed `with'respect to the frame of the burner, and pinions which coperate with the said racks and form movable fulcrums for the said levers, whereby varying movements thereof are permitted as the diaphragm is vibrated, and safety locks adapted to limit the movement of said valves.
