FRANK P. GLAZIER, OF CHELSEA, MICHIGAN.

WlCK-TUBE.

SPECIFICATION forming part of Letters Patent No. 576,447, dated February 2, 1897.

Application filed February 24:, 1896- Serial No. 580,478. (No model.)

To all whom it may concern.-

Be it known that I, FRANK P. GLAZIER, a citizen of the United States, residing at Chelsea, in the county of \Vashtenaw and State of Michigan, have invented certain new and useful Improvements in VVick-Tubes, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to an improvement in wick-tubes; and it is embodied in the constru ction hereinafter described,and definitely pointed out in the claims.

In the drawings, wherein like figures of reference designate corresponding parts in the several views, Figure 1 is avertical transverse section through the wick-tube. Fig. 2 is the blank from which the wick-tube is formed. Fig. 3 is a perspective view of the wick-tube,

showing one end partly open; and Fig. at is a horizontal section through the wick-tube just above the plane of the wick-raising shaft.

The wick-tube Ipreferably make from a single piece of sheet metal, as shown in Fig. 2, striking out of one side the housing 1 and from the other side the two parallel ribs 2, with an intermediate curved bearing 3, these parts being opposite each other when the plate is bent together on a central transverse line, as shown in Fig. 3. In each end of the housing I secure the bracket 4:, in which the ends of the wick-raising shaft 5 are journaled, this shaft being provided with suitable toothed wheels 6. The effect of this construction of wick-tube is useful in a twofold manner: First, the ribs serve to strengthen the sheet metal, so that it does not bend or buckle outward when the thrust of raising the wick comes against it, and, second, it gives a longer and deeper engagement of the teeth of the raising-wheels, thus acting to more positively raise the wick under all circumstances.

It is evident without further description that the ends of the plate, Fig. 2, are overlapped and soldered or otherwise secured together, or that the tube may be made of two separate plates of sheet metal, as desired.

What I claim as my invention is- 1. A wick-tube consisting of a single piece of metal bent to form a tube one section having the longitudinal housing 1, and the directly opposite side section being bent inward parallel with the housing to form an inwardlyextending longitudinal rib, and a wick-raiser between the housing and rib, substantially as set forth.

2. A wick-tube comprising two flat sides, one of which has a longitudinal depression in its inner face, and the directly opposite side section having longitudinal flanges bent up from the metal of the side and arranged parallel with the depression, and a wick-raiser interposed between the depression and the flanges, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
