FEED FOR OlL-BURNERS.

SPECIFICATION formingpart of Letters Patent No. 742,648, dated October 27, 1903. Application filed December 24,1il02. Serial No. 136,485. (No model.)

To all whom) it may concern: ed to receive one edge of a quadrant 15, se- Be it known that I, ALEXANDER W. HEss, a cured to the front of the furnace, and which citizen of the United States, residing at San serves as a guide for the arm during the Jose, in the county of Santa Clara and State movement thereof. Aguide-strip 16is loosely 5 5 of California, have invented new and useful mounted upon the stem 17 of valve 12 and is Improvements in Feeds for Oil-Burners, of also grooved at its outer end, as shown at 18, which the following is a specification. and this groove receives the inner edge of My invention relates to new and useful imquadrant 15 and is likewise guided thereby. provements in oil-burners especially adapted Headed studs 19 extend from opposite sides 60 for use in connection with furnaces, &c.,and of the strip 16, and one of these is adapted is more particularly an improvementin valve to engageone of a series of notches formed mechanism whereby steam and oil may be upon a strip 20, pivoted to arm 13 at a point mixed in any proportion and such mixture adjacent to the outer end thereof, while the supplied to the burner in desired quantities. remaining stud 19 engages the end of a rod 65 Another object is to provide means where- 21, pivoted to a bell-crank lever 22, which is by the valves may be operated in unison connected by means of a rod 23 to a suitable from a damper-regulator to increase or didamper-regulator.

This groove is adaptcharacter the proportions of steam and oil in adapted to by the valves may the combustible-mixture supply to the burner can be readily regulated and a practically smokeless flame produced. By means of the notched strip 20 the guide-strip 16 may be locked in any desired position in relation to arm 13, and in this way the movement of said strip and arm, and obviously of the arm 6, may be increased or diminished, thereby regulating the amount of mixture supplied to the burner.

If desired, the connections between the valve-operating mechanism and the damperregulator may be dispensed with and the valves opened or closed simultaneously by hand.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof.

Having thus described the invention, What is claimed as new is 1. In mechanism of the character described, the combination with a mixing-chamber having steam and oil inlets; of a valve in each of said inlets, a stem projecting from each of the valves, an arm secured to each stem and operate the valve thereof, an adjustable connection between said arms wherebe operated in unison, a guide-strip loosely mounted upon one of the stems and adapted to be connected to valve-0perating means, and an adjustable connection between said strip and one of the arms.

2. In mechanism of the character described,

the combination with a mixing-chamber having an outlet, steam and oil inlets, andavalve in each of said inlets; of an arm extending from each of said valves, an adjustable connection between said arms whereby the valves may be operated in unison, a fixed quadrant adapted to engage and guide one end of one of the arms, a swinging guide-strip adapted to be connected to valve-operating means and engaging and slidably mounted upon said quadrant, and an adjustable connection between said guide-strip and one of the arms of the valves.

3. In mechanism of the character described, the combination with a mixingcbamber having an outlet, inlets, a valve in each of said inlets, of an arm extending from one of the valves, a notched strip pivoted thereto, a

quadrant, an arm extending from the remaining valve and engaging and slidably mounted upon said quadrant, a lug upon the last-mentioned arm adapted to be engaged by the notched strip, a guide-strip loosely mounted upon one of the stems and engaging and slidably mounted upon the quadrant and adapted to be connected to valve-operating means, and a notched strip pivoted to one of the valve-arms and adjustably secured to said guide-strip.

In testimony whereof I affix my signature in presence of two witnesses.

ALEXANDER W. HESS.
