Specification of Letters Patent.

Application filed August 18, 1919. Serial No. 318,121.

To all whom-it may concern:

Be it"known that I, JOHN S. BRENNAN, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Wicks; and I do hereby declare that the following 1s a full, clear, and exact'description thereof.

My invention pertains to new and useful 5 improvements in. annular wicks for use in the burners of heating and cooking stoves which burn gaseous or liquid hydro-carbons as a fuel.

It is well recognized that cotton and other vantages of both of these types of wicks may be overcome by the use of a woven wick formed of threads or cords-of asbestos. It

is therefore the primary object of the invention to construct an annular wick of such material. 7

It is also an object of the invention to provide a wick, the'usefulness of which will be more than twice as great as that of the average wick of this character, this being carried out by the provision of a burning edge on each peripheral edge of the annular wick.

A still further object is to provide a combi ned supporting strip for the wick material together with means for preventing the unraveling of the non-selvaged edges of the same. v

- With these 'and other objects and advantages in view the invention resides in the novel features of construction and combination of parts which will be hereinafter particularly described. and claimed.

Referring to the drawing forming part of this application,

Figure 1 represents a planview of an annular wick constructed in accordance with my invention. 1

Fig. 2 is a plan view of the metallic supporting strip used in connection with the strip of wick material.

Fig. 3 is a similar view of the wick before the same has been bent in circular shape.

In one vaged edges ofthe strip .strip 1 so as Fig. 4 is an enlarged fragmentary view of a portion of the strip of wick material showing the manner in which thesame is woven to form a strip of predetermined width'and havlng 1ts opposite longitudinal edges sel-.

vaged. 1

Fig. 5 is a transverse sectional view taken substantially on the plane of the line 55 of Fig. 1.

In the-illustratedembodiment of the invention as depicted in the drawing the numeral 1 denotes a strip of wick material of predetermined length, said strip being a portion of a strip of indeterminate length. In other words the wick material can be woven in strips of any length and then cut into sections of the required length. As Fig. 4 the wick material consists. of warp and woof threads or cords of asbestos woven together in an ordinary manner so that the opposite or longitudinal edges are selvaged.

The wick in addition to the strip of wick Patented Jan. 13, 1920.

shown 1n STATES PATE OFFICE; A

material includesa metallic supporting strip 2 of a length greater than the length of the strip 1. The supporting strips 2 are preferably formed by stamping the same from blanks of very light gage sheet metal. Each consists of a pair of parallel bars 3 and a plurality of transverse bars 4 together with end plates 5 which extend transversely of the bars 3 and are substantially of '-a length 7 equal to the width of the strip 1. The intermediate portion of the metallic strip 2 between the end plate portions 5 thereof, or in other words the is less than the width of the strip 1. The ends of the transverse bars 4 beyond the outer edges of the bars 3 terminate in V prongs 6.

In making up a wick from one of the strips 1 of wick material and one of-the metallic strips 2, the latter is plac'ed on the former and extended longitudinallythereof with the longitudinal edges of the bars 3 equally spaced from the longitudinal sel- 1. When the prongs 6 are bent laterally and forced into the wick strip 1 and then clenched as shown in Fig. 5, the two strips are efiectively held together. The end plates are thereafter bent longitudinally of themselves or transversely of the to embrace the transverse unselvaged edges thereof. This will prevent such edges from becoming unraveled as .is obvious. The operation of straight strips 1 and 2 into circular form as distance betweenthe bars 3,

shaping the shown in Fig. 1 completes the operation of forming a wick of the character described.

In view of the fact that theimmediate portions of the strip 2- are spaced inwardly of the longitudinal peripheral edges of the strip 1, and since these last mentioned edges are selvaged, the wick can be disposed to present either of said selvaged edges as a burning edge. Thus one edge may be used until it becomes frayed or otherwise mutilated or clogged, whereupon by reversing the wick a new and clean burning edge is had. Furthermoreif so desired'one of the metallic strips 2 may be used an indefinite number of times merely by placing a strip of wick material such as the original strip when the latter' becomes worn or otherwise rendered ineffective. Various changes may be made in the form and proportion and in the manner of assembling the several parts of the invention Without departing from or sacrificing any of the features thereofQ I claim:

. 1. An improved wick comprising a woven asbestos strip having its longitudinal edges selvaged, said strip being shaped to form a rin with its non-selva ed ed es ad'acent V b O 21 tos strip to prevent the same from unravand parallel, and means for preventing said non-selvaged edges from unraveling.

2. An improved Wlck comprising a woven asbestos strip having its longitudinal edges 'selvaged, said strip being shaped to form a ring with its non-selvaged edges adjacent and parallel, and a supporting metallic ring having the asbestos ring secured thereto, a portion of the metalhc ring being ben'taround the non-selvaged edges of the asbeseling. v. 3

3. An lmproved w1ck comprlsing a rectangular strip of wick material and a metallic strip secured to the strip of wick ma-- terial and having its intermediate portion of less Width than the width of the latter, the

opposite end portions of the metallic strip termediate portion of less width than the width'of the woven strip, the opposite end portions of the metallic strip being substantially the same width as the woven strip and bent around the non-selvaged edges of the latter to prevent the same from unraveling, said strip being shaped to form a ring.

5. 'An improved wick comprising a rectangular st-rlp of woven material, a metallicstrip of rectangular shape disposed in contact with the other strip and having its intermediate portion of less width than the width of the filst mentioned strip, the opposite end portions of the. metallic strip being of substantialy the same width as the width or the first mentioned strip and bent around the transverse edges of the latter,

and prongs extending from the longitudinal edges of the intermediate portion of the metallic strip and bent into the other strip to secure the two strips together, said strips be ing shaped to form a ring.

In testimony that I claim the foregoing I,

have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of WIS- consin. I
