OIL-BURNER.
Specification of Letters Patent.
Patented June 15, 1915.
Application filed m 10, 1912. 7 Serial No. 708,599.
To all whom it may concern:
Be it known that we,"Wn.LrAM-R. J nevons and ARNOLD R. Wrrrrmnnn, citizens of the United States, residing at Cleveland, in the county of Cuyahogaand State of Ohio, have invented a certain new and'us'eful Improvement in Oil-Burners, of which the following is a full, clear, and exact description, re erence beinghad to the accompanyingdrawings. I
This invention relates to oil burners of the type wherein there is a pair of Wick tubes and an air distributer havin a spreader extending across and spaced om the top of the wick tubes, the inner Wick tube being provided with a seat for the distributer, formed preferably as a spanner comprising an outer and an inner ring'and connected by arms, the inner ring havin a central guide opening for the spindle which depends from the central portion of the distributer.
As heretofore constructed, the distributor has been supported by means of a spreader of the character hereinbefore described having a vertically extending annular flange at its periphery, which flange has been secured to the inner tube by means of solder. In operation, the parts are liable to be so subjected to heat as to melt the solder, with the result that the support for the distributer'will become dislodged, leaving the distributer with no means for supporting and centering the same. In burners of this type it is exceedingly important that the spread-. ers shall be at a predetermined distance from the tops of the wick tubes. Should the support for the distributor, of which the spreader forms a part, become'loosened or have its position altered in a vertical direction, the distance between the spreader and the, tops of the wick tubes would be correspondingly affected with the result that the burner will not properly function.
It is the purpose of this invention to provide an extremely efiicient, though simple, means whereby the distributer support or spanner may be anchored securely in place 'within the inner wick tube without any liability to become dislodged.
\Vith the foregoing objects in view the invention may be defined further and more generally as consisting of the combinations of elements embodied in the claims hereto annexed and illustrated in the drawings forming a part hereof, wherein- Figure 1 represents a vertical sectional view taken through a portion of the oil stove burner, illustrating the manner, of supporting the spanner within the inner wick tube; Fig. 2 represents a transverse sectional view taken through the inner, wick tube of the aforesaid burner and showing the projections whereby the distributer support is anchored in place, the view being taken on approximately the line 2-2 of Fig. 3; Fig.
3 represents an elevation of the portion of";
theinner wick tube which is provided with 3 the anchoring projections, and Fi 4 an enlarged sectional detail illustrating the.
manner in which the outer edge of the dis- 1 tributer support is held in place.
Describingthe various parts illustrated herein by means of reference characters, 1
re resents the inner and 2 the outer wick.
tu e of a burner, said tubes having in terposed therebetween a wick 3, which may .be raised and lowered by means of a wick raising shaft having an operating handle 4. Within the interior of the inner wick tube there is located an air distributor and spreader, which is, of the type shown in the atent to Jeavons No. 871,593 issuedNovem- 7 er 19, 1907. This combined air distributor and-spreader comprises a ring 5 having perforations at the upper end thereof, the ring being connectedto a neck 6, to the top of which are attached the spreader plates 7 and 8. The spindle 9 is connected to the upper spreader plate and depends centrally therefrom within the neck 6 and ring 5. Depending from the bottom of the distributer and spreader is a locking device having dependinghorizontal shoulders 11 which normally extend beneath the arms 12 of the spider.
The vertical movement of the distributer.
sol
therein by means of an up er and a lower series of inwardly extending projections ressed from the body of the wick tube.
he upper series of projections 16 and the lower series of projections 17 are preferably formed'in the wick tube after the spider is inserted in place, the two series being vertically spaced to receive snugly therebetween the outer edge of the supporting ring or plate 14 7 (see particularly Fig. 4). In forming these projections in the light sheet metal of which the inner wick tube is composed, there is great danger that the metal will be so drawn or stretched as to afford an lns'ecure support for the distributer support, if, in fact, the support is not allowed to drop by reason of the stretching action referred to. To avoid stretchin the metal to this extent and at the same time to provide avery secure anchoring means for the distributer support, the projections in each series are spaced laterally a considerable distance apart,greater than the width of a projection (or the width of the recess caused by forming a projection)and the projections of one series are staggered with respect to those of the other series. This arrangement will be clear from Fi 3. The projections may be conveniently ormed by means of two toothed wheels placed side by side on ,a common arbor, or by a double toothed wheel, the teeth bein of such width and so spaced as to provide t e arrangement of projections shown in the drawings.
The anchoring means described herein is one obtainable in an extremely simple manner and may be produced at very small expense. It has, however, been found to be extremely efiicient in use.
Having thus described our invention, what we claim is 1. In an oil burner, the combination, with a cylindrical metal tube adapted to form the internal support for a circular wick, of a supporting member located within said tube and engaging the walls thereof, said tube being provided with an u per and a lower series of circularly spaced projections extending inwardly rem the inner wall there- -of above and below the outer edge of said supporting member.
. circularly 2. In an oil burner, the combination, with a cylindrical metal tube adapted to form the internal support for a wick, of a supporting member located within said tube and having its outer edge abutting against formed by pressing form the internal support for a wick, of
a supporting member located within said tube and having its outer edge abutting against the interior wall of said tube, said tube having an upper and a lower series of spaced internal projections formed by embossing the metal of the tube andreeeiving between them the outer edge e of said supporting member, the distance between adjacent projections of each series hemg greater than the width of a projection,
and the projections of oneseries being staggored with respect to tliose'of the other semes.
4. In an oil burner, the combination, with a cylindrical metal tube adapted to form an inner wick' tube, of a supporting member or spanner of substantially the same external diameter as the internal diameter of said spanner, the distance between adjacent projections of each series being greater than the width of a projection.
In testimony whereof, we hereunto atiix our s gnatures in the. presence of two wit nesses.
