CHRISTIAN G. PFAI-ILER, or mi rsro, orrro, assieivoit or ONE-HALF TO CONDI'I o. PARSONS, OF LEIPsIo, OHIO.
OIL-BURNER FOR STOVES.
Application filed 0ctober 16, 1-919.
To all whom it may concern:
Be it known that I, CHRISTIAN G. PFAH- min, a citizen of the United States, and a resident of Leipsic, in the county ofPutnam and State of Ohio, have invented certain new and useful Oil-Burners for Stoves; and I do hereby declare the following to be a full clear, and exact description of the invention, such as will enable others .skilled in the art to which it apperta-ins to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.
My invention has for its object to provide in oil burners having a wick for supplying fuel to the flame, a means for controlling the wick and thereby controlling the amount of fuel. It'particularly has for its object to provide a means for manipulating the wick which will not bind or stick and thus permit control of the fuel. It also has for its object to provide a means whereby practically all of the wick, which is grad ually consumedin the continuous use of the burner, may be utilized.
Constructions containing the invention may be modified in their details without departing from the spirit of the invention. For purposes of illustration and description I have selected a burner containing my invention and shall describe it hereinafter. The burner selected is illustrated in the accompanying drawings.
Figure 1 of the drawings illustrates a side view of the burner and its chimney. Fig. 2 is a transverse sectional view taken 'on the line 22 indicated in Fig. 1. Fig. 3
is a broken view showing the manner of support of the bearing illustrated also in Fig. 2.
In the drawings, 1 is a shell which contains or forms a part of the oil burner and 2 is the chimney which is located above the burner to give the proper draft and opportunity for complete combustion of the fuel in a manner well known in the art. 3 is the nipple for connecting the burner with the suitable source of liquid fuel supply. The fuel passes through the nipple or connector 3 to the interior of the shell 1.
The wick 4, preferably in the form of a sleeve, is located within the shell 1. The shell 1 is provided with an interiorcoaxial shell 5 which is connected with the lower end of the shell 1. This leaves an annular Specification of Letters Patent.
Patented Feb. 17, 1920.
Serial No. 330,975.
chamber between the shells in which the wick 4 is located. The wick 4 is secured by any suitable means between the rings 6 and 7. The ring 6 fits on the inner shell 5. It may be made thick and broad in order to present a broad bearing surface to the shell 5. It'may be provided with an outwardly extending lip 8 against which the lower edge of the wick 4 may be placed, and the ring 7, which tightly fits the wick 4 when placed around the ring 6, may be forced over the lower end of the wick 4 and the ring 6. The ring 7 is provided with a pin 9 which extends through a vertical slot 10 which is formed in one side of the shell 1. It also extends through the side of a block 11 which has the central bore 12. The pin 9 extends into the bore 12 and in between adjoining turns of the screw 13. Rotation of the screw 13 causes the thread to press against the pin 9 and raise and lower the rings 7 and 8 and the wick 4 attached thereto. The block 11 prevents lateral displacement of thepin 9 relative to the screw 13 and thus causes the thread to move the pin 9 up or down according to the direction of rotation of the screw 13 and consequently to raise or lower the wick 4. The slot 10 is covered by an oblong rectangular box 14 forming a chamber 15 for the screw 13 and at the same time prevents the escape of the fuel from between the shells 1 and 5. The block 11 fits the chamber 15 and consequently the box 14 forms a guide to the substantially cubical block 11 and prevents rotation of the block 11 with the screw 13 when the screw 13 is turned. The upper end of the chamber 15 is closed by means of the cap 16 which has a bearing 17 for the upper end of the screw member 13. The bearing block 17 is secured to the under side of the cap 16. The cap 16 fits over the top of the box and has a flange 18 that fits up against the upper edge of the shell 1. The cap is held closed and in position to support or guide the upper end of the screw 13 by means of the spring clip 19 which yieldingly presses on the top of the cap 16. The cap 16 and the bearing 17 may be removed by bending the spring clip 19 back and lifting the cap from the upper end of the box 14, when the wick is to be connected to the block 11 by means of the pin 9 and the rings 6 and 7, and the pin may be inserted through the slot 10 and into the opening in the block 11 formed in the side of the block to receive the pin. This may be done at the top of the box 14 and then the threaded member may be rotated to place the wick wherever it may be desired.
The lower end of the box 14 is closed by a block or plug 20 having a recess 21 in which is located a packing nut 22 through which the end of the screw member 13 extends. Escape of the oil is thus prevented around the screw member 13. The screw member 13 is rotated to raise and lower the wick by the handle 23 which is connected to the lower end of the screw member.
The wick 4 may be maintained close to the outer wall of the shell 1 by means of the shell 24 which fits around the shell 5. This also closes the space between the wick 4 and the shell 5 and prevents the striking back of the flame from the surface of the oil or from the gas rising from the oil that is lo cated in the annular chamber formed between the shells 1 and 5.
. A depending tube 25 may be connected to the shell 24 in which the rod 26 may be located. The rod 26 is connected to a spider 27 which is connected to or supports the chimney 2. The lower end of the rod 26 may be connected to a suitable means for raising or lowering the rod and consequently the chimney 2 to permit lighting of the wick 4. In the construction shown the lower end of the rod 26 is connected to an angular arm 28 which moves in a stirrup 29 when raised to lift the chimney so that the user may light the wick by the use of a match extending to the wick below the lower edge of the chimney.
I claim 1. In a fuel burner, a Wick, a ring connected to the lower end of the wick, a threaded member, a block surrounding the threaded member, means for guiding the block for longitudinal movement along the threaded member and for preventing rotation of the block, and a pin connected to the said ring and extending through the said block and in between two consecutive turns of the thread of the threaded member for raising and lowering the wick by rotation of the threaded member.
2. In a fuel burner, a wick, a ring connected to the lower end of the wick, a threaded member, a block surrounding the threaded member, means for guiding the block for longitudinal movement along the threaded member and for preventing rotation of the block, a pin connected to the said ring and extending through the said block and in between two consecutive turns of the thread of the threaded member for raising and lowering the wick by rotation of the threaded member, a bearing located at the upper end of the threaded member, a cap connected to the said bearing, and a spring for holding the said cap in its closed position. 7
In testimony whereof I have hereunto signed my name to this specification.
