Patented Sept. 24, 19117.

To all whom it may concer-n:

lBe it known that I, LEVI HOLBEEN, a citizen of the United States, residing at the city and county oi Sanv Francisco and State of California, have invented new and useful Improvements in Automatic 'Fue1-l`tegu laters, of which the i'ollowing is a specification.

My invention relates to an apparatus for automatically are supplied ior combustion in furnaces.

It consists in the combination of parts and in details of'construction which will be more fully explained by reference to the accompanying drawings, in which- Figure 1 is a side elevation showing my invention in vposition. Fig. is an enlarged section of a portion of the apparatus. Fig. 3 Yis a' view transversely just below the cylinder. o

A is a bracket or support of any description which may be attachedto the front of the boiler as at B, ory

upon any suitable or desired support in convenient proximity to the b oiler or furnace Where the work is to be done. This bracket is here shown contrived to support a cylinder 2,'in which a plunger'3 is fitted to reciprecate. This plunger is reduced as shown at 4, and continued in the form of a stem 5, which stem is slidable through a screw-threaded sleeve 6, which serves as' a guide to maintain the movements of the plunger in a direct line. A,

7 is a disk or plate having a hole through it, said hole .being divergent at the upper side of the plate so as to t 3 0 against the conical portion 4 between the piston and stem. This disk has a slot or chan nel made transversely across its lower face, and adapted to receive a bar which fits in the slot 4as shown at 8. This bar extends horizontally and has its end forked as shown at 9, and this fork fits,- and is slidable upon a rib or projection l() of the bracket A; thus the disk 7 is prevented from turning. This disk has arms 1l and l1n projecting from it at right angles from the line oi the arm 8, and these arms carry portions oi the regulating mechanism to be hereafter described.

The oflce oi the disk 7 and its interlocking bar 8 is to normally hold the arms 1l and l1'l in their proper position and to allow them to b e reversed so as to project to the opposite side of thestem 5 when desired.

12 is a disk against which the upper end of a spring 13 lits and is seated. The lower end oi this spring contacts with and is supported by a disk .or plate 14 which is carried upon the upper end of the screw-threaded sleeve 6. This sleeve passes through the screw-threaded lower hubpr boss l5 of the bracket A, and by turning the screwthreaded portion the springf may be either compressed to increase its tension or relaxed, and the tension reduced for a purpose to 'be hereafter described.

To the ends oi the arms 11-l1,are connected the upper ends of links 16--16; the lower ends of these links being made hollow and screw-threaded to re i ceive a rod 17, the upper end oi which may have a are two othese rods 17--177 one connecting with each oi the arms 111-11, and the lower ends of these rods are connected with the crank or lever arms 18-18LL which serve to turn cocks l9-19a controlling a passage through each ei the pipes 20-20a. These pipes supply oil and steam to a burner 2l and the proportions of oil and steam thus supplied are regu-A lated by turning the rods 17 which, being right and left screw-threaded at opposite ends will, when turned in one direction, lengthen the distance between the levers 11-11* and the levers 18e-18 and when turned in the opposite direction will correspondingly shorten the distance, so that the cocks will be opened more or less according to the adjustment, and the proper proportion of steam and oil can be delicately regulate In order to move theplunger 3 within the cylinder 2, and thus move the arms 1111'L and connected parts, 1 haveshown a pipe 22 connected with the boiler so as to deliver steam into the upper part of the cylinder 2. If,. for example, it be desired to carry 150 lbs. pressure oi steam in the boiler, the fire is so regulated that steam will be raised to such pressure in the boiler, and the tension of the spring 13 reached, it will prevent the piston or plunger from being forced down, and the adjustment of the rod 17 will so control the steam and oil cocks that the amount admitted will be suilicient to approximately maintain this pressure. If the pressure rises above the desired figure, the upward pressure of the spring l13 will be overcome by the downward pressure upon the plunger 3, the spring 13 will be compressed and the arms ll-l1fL caused te move downward with it, thus partially closing the cocks and reducing the fire so that the steam pressure will shortly be brought to the normal. ll the pressure becomes reduced below the desired figure, the pressure of the spring 13 will overcome that of the plunger 3, and the connected parts will be forced upwardly, thus opening the steam and oilsupply cocks, and increasing the ire until the steam pressure in the boiler has again reached the normal.

I have described vthis apparatus as being adapted to control a re in which oil and steam are intermingled; but it will be obvious that the same device may be used to control an air supply under pressure in place of or in conjunction with the steam pressure; and anyother equivalent means for promoting the ire under the boiler to make steam which can be used in turn. to regulate the supply.

One cock-controlling lever may have a litt-le more throw than the other, so that there will be a proper` tionate difference in the opening or closing of the right and the lower end a left screw-thread. There l will be so regulated that until this pressure has been steam and oil cocks, to maintain a certain desired proportion of these elements delivered to the burner.l

Having thus described my invention what I claim and desire to secure by Letters Patent isplunger, u disk having a transverse slot into which one ofy said arme is fitted, said arm having n -guided `fork at theupper end, n spring, disks surroundingthe Astein below said arm and between which the spring is located so as to press upwardly and retain the arms normally in their higher position, a screw thread cut upon the sleeve passing through a correspondingly threaded iixed nut whereby the lower spring supporting disk will he moved to increase or diminish the tension of the spring, means for admitting stenln from the boiler into the upper end of the cylinder, a structure with viilve controlled steam and oil pipes leading thereto, and means between `the spring and plunger controlled arms whereby the valves are opened-or closed.

2. In an apparatus of the character described, a verti= cally disposed cylinder having a plunger movable therein and n guided stem, means for supplying steam from the boiler to the upper end ot the cylinder to depress ilic plunger, an adjustable spring actingln opposition to the plunger, and means tor regulating its adjustment, u transversely Slotted diskfagaihst which the spring nets in opposition to the plunger pressure, an'arm fitting the transverse slot having a guided fork nt the outer end, arms projecting from the disk, a burner, menns for supplying iiuidsvunder pressureto said burner, controlling` cocks und connections between said cocks and the disk-carried arms, said arms being reversible in the slotteddlsk to transfer the mechanism to one side orthe other of the cyl luder axis.

Invtestlmony whereof 'I have hereunto set my hand in presence of two subscribing Witnesses.

LEVI HOLBEN.
