PAUL J. GRINBERG, OF NEW YORK, Y.

WICK-TUBE.

SPECIFICATION forming part of Letters Patent No. 431,577, dated July 8, 1890.

Application filed March 28, 1890. Serial No. 345,647. (No model.)

To all whom t may concern.-

Be it known that I, PAUL J. GRINBERG, of New York city, New York, have invented an Improved Vick-Tube, of which the following isa specification.

This invention relates to a wick-tube for oil-stoves, so constructed that the, tubular bearings for the wick-raising shaft are formed directly upon the housing. To this effect the housing is struck up together with the bearings, and is then soldered over a slot in the wick-tube proper.

The invention consists in the various features of improvement more fully pointed out in the claims.

In the accompanying drawings, Figure l is a face View of the housing detached; Fig. 2, a side view at right angles to Fig. 1; Fig. 3, a face view of the blank for forming the Wicktube before being bent; Fig. 4, an edge view thereof; Fig. 5, a vertical longitudinal section of the completed wick-tube with the housing and wick-raiserin place; Fig. G, a side view of the completed wick-tube; Fig. 7, an end View of the housing with the wick-raiser in place Fig. S, a side view of a portion of a housing, showing a modification; and Fig. 9, an end view thereof.

The letter a represents arectangular sheet of metal adapted to be bent upon the dotted double lines shown in Fig. A3, so as to constitute the wick-tube. The free ends of the wick -tube are connected by ythe lapjoint shown in Fig. 5, and thus the entire wicktube is formed froin'one continuous piece of sheet metal. Within one section of the wicktube a there is cut a longitudinal slot a', over which the housing is subsequently attached. Through this opening the Wick-raiser, turning within the housing, reaches the wick. The two short sides of opening a. are punched out to form four lugs CL2, and between them the bearings a3. These bearings subsequently receive the wick-raising shaft. The lugs a2 are bent outward at right angles, so as to subsequently enter the housing, Fig. 5.

The housing b is struck up in Va die from a rectangular piece of sheet metal, so as to assume the usual trough shape. At its ends, however, there are struck up simultaneously with the housing the semi-tubular bearings b', as shown.

In putting the device together the wickraising shaft c is slipped into bearings a3, and then the housing is soldered against the Wicktube, so as to close the opening a', and of course to inclose the lugs a2 and bearings as. The two semi-tubular bearings b will embrace the shaft c beyond the bearings a3 to conceal the lugs a2 and form the proper finish.

In Fig. 8 one of tubes Z9 is somewhat lengthened, and is provided at its ends with downwardly-depending lugs b2. These lugs project beyond the edge of the wick-tube a, after the housing has been soldered to such wicktube, and may be coiled around the shaft c, s

as shown in Fig. 9, to form a complete circular bearing.

The advantage of my improved wick-tube is that the bearings b may be formed in one operation with and directly upon the housing b. Moreover, the Worm c on the star-Wheels for raising the Wick may be soldered to the shaft c before the shaft is putin place Within the housing. The entire device, though simple, presents a perfect finish when completed.

Vhat I claim isv 1, The combination of wick-tube d, having` slot a', and outwardly-bent lugs a2, with housing b, secured to the wick-tube over slot a', and with the wick-raiser c, received between lugs a2, substantially as specified.

2. The combination of slotted wick-tube a, having outwardly-bent lugs a2, with the housing b, having tubular bearings b', and secured to tube a, and with Wick-raiser c, substantially as specified.

3. The combination of slotted wick-tube ct with housing b, having semi-tubularbearings i Witnesses:
