My invention relates to improvements in oil stove wicks, and it consists in the combinations, constructions and arrangements herein described and claimed.
One objection to the use of oil stoves is the fact that the ordinary fabric wicks burn or char, and this makes an uneven flame. It necessitates the trimming of the wick frequently. In order I to obviate the burning of the wick various forms of refractory wicks have been used such as those made of asbestos. An asbestos wick, however, does not have the capillary attraction for oil that a wick such as a cotton wick would have,
I and the feeding of the oil is therefore retarded,
some times to such an extent as to decrease the flame to a point beyond normal.
Another difficulty experienced with asbestos wicks is that if food which is being cooked boils over and spills on the wick the attempt to remove the food causes the disintegration of the wick, since the asbestos wick cannot stand the same handling that the ordinary fabric wick can stand.
A further objection to the use of asbestos wicks is that the handling or adjustment of the wick will often cause the fibers to loosen up to such an extent that the wick soon becomes Worthless for use.
An object of my invention is to provide a refractory wick which is strengthened by reinforcing layer partly made of metal, thus preventing the disintegration of the wick due to handling or adjustment and greatly prolonging the life of the wick.
A further object of the invention is to provide a wick which will not be consumed but which has a layer of fabric whereby the oil is more readily conducted to the upper portion, thus obviating the objection found with the ordinary asbestos wick which does not have this fabric layer extending substantially to the flame.
A further object of the invention is to provide a wick of the asbestos type in which the upper portion of the wick will not disintegrate as readily since it is supported by the reinforcing layer.
Other objects and advantages will appear in the following specification and the novel features of the invention will be particularly pointed out in the appended claims.
My invention is illustrated in the accompanying drawings forming part of this application, in which:
Figure 1 is a sectional view through a burner sleeve with my improved wick applied thereto.
Figure 2 is a side elevation of the sleeve and wick shown in Figure 1.
Figure 3 is a plan view of the part shown in Figure 1. I
Figure 4 is an enlarged cross sectional view of 61? the wick showing the various layers and the holding member for the burner.
Figure 5 is a plan view of a modified form of the wick.
Figure 6 is an edge view of Figure 5, and,
Figure. 7 is an enlarged cross sectional view of a portion of the wick.
Referring now to Figure 1, I have shown therein a wick sleeve 1 and retaining members 5 which are spaced apart from the sleeve 1 and which are to be found in any ordinary burner. The wick is held between these members. It consists of layers 2 of asbestos fabric. Between these layers 2 is an oil conducting layer 3 made of cotton or similar fabric. A fourth layer con-v sists of a wire screen impregnated with asbestos fiber and flour. The impregnation may be made in any suitable manner as by 'applying a paste to the screen and then pressing and. drying it. The screen itself is preferably made of copper, although it may be made of other metal. The layers are held together by copper staples 6. which are disposed at intervals, as shown in Figure 1.
It will be noted that the oil conducting layer 3 and the reinforcing layer 4 terminates short of the top of the wick, leaving a short length 21: of the layers 'of the asbestos projecting beyond.
A wick constructed according to the invention will readily conduct the oil to the portion 2.1: so that there is a steady flow of oil. This insures a steady flame and when the wick is adjusted to a certain position the flame will remain steady as long as there is any oil in the stove. Should the food boil over and flow down on the wick, the removal of the food will not disintegrate the wick due to the reinforcement given by the layer 4. The latter layer also tends to strengthen the wick so that when it is handled or adjusted the asbestos layers will be protected from bending or distortion, thereby increasing the life of the wick. The use of copper staples prevents the separation of the layers, and since the copper is not easily oxidized as would staples made of iron, there is no danger of their giving away.
In Figures 5, 6, and '7 I have shown a modified form of the invention. In this form the layers I are all flat strips. As will be seen from Figure no 7, there are two asbestos layers 2. These layers are held between reinforcing layers consisting of copper wire impregnated with asbestos fiber and flour. In making the wick the reinforcing layer is bent around the bottom of the asbestos strips and brought up closely on the sides thereof to form layers 7. The layers are held together by means of staples 8 along the edges of the wick. v i
In this form, as in the form'shown in Figures 1 to 4 inclusive, the asbestos layers are reinforced by the wire screen layer, but in this form the fabric wick such as cotton, is dispensed with.
The outer layers with the wire screen form a protecting cover and also aid in conveying the oil, since the fibers with which thescreen vis impregnated carry the oil by capillary attraction.
I claim:-- I
tos fibers and flour, said cotton layer and said reinforcing layer terminating short of the upper end of the wick.
3 In a wick construction, spaced apart asbestos layers, a cotton wick disposed between'said asbestos layers and a reinforcing layer, said reinforcing layer and said cotton wick terminating short of the upper end of the wick. FRANK A. JEFFERSON.
