VALVE.

SPECIFICATION forming part of Letters Patent No. 435,630, dated September 2, 1890.

Application tiled April 18, 1890. Serial N0.'348,447. (No model.) r

To all whom it'mcty concern.

Be it known that I, CLEMENT R. lIoorEs, 0f Ogontz, county of Montgomery, and State of Pennsylvania, have invented an Improvement in Valves, of which the following is a specification.

My invention relates to valves; and it consists of certain improvements which are fully set forth in the following specification, and Shown in the accompanying drawings, which form a part thereof.

My invention is more particularly intended as an oil-valve to control and automatically shutoff, when desired, the flow of oil to an oil-burner.

In Letters Patent No. 379,468, issued to me on the 13th day of March, A. D. 1888, is disclosed an oil-burner, to use upon which my improved valve is particularly adapted, and it is shown applied thereto in the accompanying drawings. I do not, however, limit my invention to use upon such a device, as it is apparent that it may be used upon any other apparatus adapted to it. More or less diniculty, attended with commensurate danger, is met with in oil-burners due to ooding by the oil, owing to imperfect controlling of the flow of the oil or a failure to shutoff the supply of oil when for any reason the .burner ceases to operate.

The obj ect of my invention is to provide an oil-burner with suitable valve mechanism to control the flow of oil, and in the case of any sudden stoppage of the apparatus to instantly shut olf all supply.

rlhe details and operation of my improved valve are more fully set forth hereinafter in the description of the drawings, in whichm Figure l is a side elevation of an oil-burner having my improved valve applied thereto. Fig. 2 is a sectional side elevation, on an en larged scale, of the valve mechanism. Fig. 3 is a plan view of the same, and Fig. 4 is a plan view of one of the detached pistons of the valve.

A is the furnace, and B is the floor thereof.

C is the burner which enters the furnace at one end. As heretofore stated, the details of this burner are immaterial to the present invention, though I prefer the construction disclosed in my Letters Patent before rcferred to.

Il is an oil tank or reservoir, from which the oil is fed by a pipe I, provided with a valve J.

D is the valve-chamber into which the oilsupply pipe I opens.

Eis a distributing-pipe leading from the valve-chamber D to the oil-burner to supply the oil thereto.

F is a stem or rod in the valve-chamber, vertically movable therein and having its end extending ont through the cap or cover of the valveehamber D.

G is a lever pivoted to the cap or cover of the chamber D at g, and connected to the ends of the stem F.

K is a weight carried by the lever G and movable thereon. I prefer to provide this weight with an anti-friction roller 7a.

L is an adjustable stop to limit the descent of the weight K when the lever is raised. The end of the lever G is also provided with a stop M to prevent the weight falling off when the lever descends.

Carried by the rod F are two disks or pistons N and O, separated from each other a short distance, the upper one N being solid, and the lower O provided with openings o to allow the oil to flow to the outlet-pipe E. The oil-inlet pipe I opens between these pistons N and O when they are in their normal positions.

P vis an air-pipe opening into the valvechamber above the closed piston or disk N. By this pipe air under pressure is supplied to the valve-chamber.

In the apparatus disclosed in the patent heretofore referred to superheated air under pressure is admitted to the oil before it is introduced into the furnace, and in the drawings I have shown this air-pipe P as leading from the superheating-coil Q. It is apparent, however, that the air may be led from the blower or fan without passing through the superheating-coil Q, as indicated in dotted lines in Fig. 1. Normally, when the apparatus is in operation and the valve is open, it is in the position shown in Fig. 2. The lever Gr extends upwardly, and the tendency of the weight K is obviously to depress the lever and raise the rod F. The pressure of the air through the pipe I upon the upper disk N prevents this and keeps the valve open, allow- IOO ing the inlet ot' the pipe I by the piston O.n

Thus the flow of VYoil will be instantly stopped, so that ooding will be impossible. IVhen it is desired to start the oil-supply again, the lever G must be raised to its normal position. I prefer to fulcrum the lever G at gin a block R, which, by means of an adj usting-screw r, may be raised or lowered.4

While I prefer the details of construction which are here shown, it is apparent that they may be modified in many ways without departing from the principles oi' my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination ot' a chamber having an inlet and an outlet for oil or other liquid, a valve to control said inlet, a lever connected with said valve, a movable weight carried by said lever and tending normally to close the valve, and devices, substantially as described, actuated by the pressure of steam or air, connected with said valve and operating against the action of said weighted lever, whereby when said pressure ceases the valve is automatically and permanently closed by the action of said Weighted lever.

2. The combination of 'a chamberhaving an inlet and an outlet for the oil, &c., a rod mov- .able therein, a piston carried by said rod, an

inlet for air under pressure above said piston, a valve carried by said rod adapted to close the oil-inlet when raised, a pivoted lever having one arm connected to said rod, and a sliding weight tending to depress said lever, whereby when the pressure above said piston ceases the valve will be raised and will automatically close the inlet. l

3. The combination of a chamber having an inlet and an outlet for the oil, 85e., arod movable therein, a piston carried by said rod, an inlet for air under pressure above said piston, a valve carried by said rod adapted to close the oil-inlet when raised, a pivoted lever having one arm connected to said rod, a sliding Weight movable on said rod, and an adjustable stop carried by said rod to adjust the normal position of the weight, whereby when the pressure above the piston ceases the valve Will be automatically raised by the action of the Weight upon the lever and will permanently close the inlet.

In testimony of which invention I have hereunto set my hand.
