ATTACHMENT FOR BURNERS.

Specification of Letters Patent.

Patented Nov. 14, 1916.

Application filed. March 21, 1916. Serial No. 85,659.

To all whom it may concern Be it known that I, ELLSWORTH D. KEL- LnRnAN, a citizen of the United States, residing at Montesano, in the county of Che halis and State ofVVashington, have invented certain new and useful Improvements in Attachments for Burners, of which the following is a specification.

My invention relates to an attachment,

adapted for use in combination with an incubator burner, perferably employing a liquid fuel, such as oil.

An important object of the invention is to provide an attachment of the above mentioned character, adapted to cut down the flame, while not extinguishing it, for reducing the heat given off by the burner, such attachment being preferably automatically operated by the thermostat of the incubator.

A further object of the invention is to provide means whereby the plates, employed to reduce the flame, are adjustably mounted upon their carriers, to act upon flames of different length, in accordance with the adjustment of the wick.

A further object of the invention is to provide an attachment of the above mentioned character, which is extremely simple in construction, inexpensive to manufacture, convenient in use, and reliable in operation.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a plan view of an attachment embodying the invention, Fig. 2 is a side elevation of the same, parts being in section, and Fig. 3 is a similar view taken at a right angle to Fig. 2.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates the body portion of a burner, such as an oil burner, having an adjustable device 6, to raise and lower the wick, which operates within a wick tube 7 Pivoted to the body portion 5 is the usual cover 8, adapted to be moved to a closed position, surrounding the wick tube 7.

The numeral 9 designates a rock-shaft, provided at its outer end with a crank 10. This rock-shaft is journaled through openings formed in the body portion 5 and can ries stop rings 5, as shown. The rock-shaft 9 is provided within the body portion 5 with an upstanding crank-loop or inverted U-shaped member 12. Arranged near the rock-shai't 9 and extending in parallel relation thereto is a co-acting short rock-shaft ing stop rings 13 to prevent its longitudinal displacement. This co-acting rock-shaft is provided with an upstanding loop-crank or inverted U-shaped, member 14, identical with the member 12.

The rock shaft 9 is provided at one end with a loop-crank 15, pivotally receiving the hooked end 16 of the rock-shaft 13. It is thus apparent that when the crank 10 is swung upwardly, the cranks 15 and 16 will co-act, to swing the rock-shaft 13 inwardly, whereby the members 12 and 14 will be swung toward each other. Arranged upon each of the members 12 and 14 is a plate 17, having its corners bent inwardly, as shown at 18, and its central portion of its upper edge outwardly, as shown at 18. Each plate 17 is provided at its vertical edges with tubular sockets 20, receiving the vertical arms of the inverted U-shaped memher and having proper clamping engagement therewith. By virtue of the tubular sockets 20 each plate 17 will remain in adjustment upon the vertical arms of the inverted U-shaped member but the plate may be longitudinally adjusted thereon and held in adjustment at the desired position. The function of adjusting the plate 17 longitudinally of its supporting member, is to provide means whereby the same may properly co-act with flames of different lengths, depending upon the permanent adjustment of the wick.

In the use of the apparatus, the burner having my attachment is employed in an incubator in the usual manner. The crank 10 is suitably connected with a thermostat apparatus, such as illustrated in Letters Patent No. 856,043, granted to Martin Flanders, June 4, 1907, while the invention is of course in no sense restricted to this use. Under normal conditions the plates 17 are open, thus not obstructing the flame. When the heat rises in the incubator above a predetermined point, the thermostat device 0perates to swing the crank 10 upwardly.

This causes the rock shafts 9 and 13 to turn inwardly toward each other, whereby the plates 17 are moved to the inner position upon opposite sides and in proximity to the wick tube 7, thus cutting down the flame.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to Without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described the invention, I claim:

An attachment of the character described, comprising a main r'ocloshaft having an upstanding inverted approximately U-shaped member, a co-acting rock-shaft having an ELLSWORTH D. KELLERMAN.
