OIL-STOVE.

SPECIFICATION forming part of Letters Patent No. 653,894, dated July 17, 1900.

Application filed April 18, 1899.

T0 at whom it may concern:

Be it known that I, WILLIAM H. WILDER, a citizen of the United States,residing at Gardner, Massachusetts, have invented certain new and useful Improvements in Oil-Stoves, of which the following is a specification.

My invention relates to that class of stoves now known to the trade as the F automatic, adapted for the use of oil to burn a blue flame, the burner and reservoir having movement in relation to each other whereby upon the movement of one or the other of said parts the burner is partially or wholly filled or partially or wholly drained, the oil in the reservoir being maintained at a constant level, and in the movement of the parts the burner is moved across this level to fill or empty the same wholly or partially, or the level is raised or lowered bodily by the adjustment of the oil-tank to vary this level in relation to the burner, all as fully set forth in various patents of the United States heretofore granted me.

The present invention includes many details of construction by which the cost of production has been decreased by the reduction of the number of parts and the manner of arranging these parts, all as hereinafter fully described.

In the accompanying drawings, Figure 1 is a front elevation of the stove shown in cabinet form with the front door open. Fig. 2 is a vertical section through the cabinet, showing the parts of one burner in side elevation. Fig. 3 is an end elevation of the stove, showing the reservoir. Figs. 4 and 5 show details. Fig. 6 is a detail of an indicating-plate attached to the front door of the cabinet.

In the drawings I have shown the stove with a cabinet-frame instead of the skeleton frame commonly used, and this is advantageous, as it enables me to use a simpler construction of combustion-tubes and renders unnecessary the external shields made necessary by the use of a skeleton frame. This cabinet-frame consists of a base A, composed of sheet metal, the front and end walls forming a rectangular frame with a door a at the front. The top and bottom of this base are composed of sheet metal exactly alike, but

Serial No. 713,494. (No model.)

reversed in position, as shown in Fig. 2, and these plates 17 0 have their edges dished, as at cl, to fit over the upper and lower edges of the walls of the rectangular base A, while the parts are held together by wire rods 6, passing through the interior of the space of the base A and provided on their lower ends with nuts f. Thus it will be seen that the parts can be readily put together and as readily detached. Seatedupon the base is the body B, this being slightly smaller than the base and having rounded corners. The lower edge fits within the depression of the plate I), this depression being formed by the upwardly-curved edges of the said plate, as shown at (Z. base and the shape of the upper body part B, with its rounded corners, presents a very attractive appearance and adds to the gen eral beauty of the stove. The body portion is perforated at the back to allow the admission of sufficient air, as shown at g. 1

The burners C have a sliding connection with vertical extensions h of a horizontal pipe line i, and thispipe at one end extends out side the end of the body portion and is held in place by astrap k. The end of the pipe is closed by a removable plug Z,- which may be taken out for cleaning the pipe should this be found necessary. At its opposite end a strap m clamps it to the top of the plate I). The ends of this strap are continued up wardly, as shown at n, and serve to support the oil-chamber o, to the bottom of which the pipe 71 connects. Centrally of the pipe 4; two parts of a casting are clamped, having extensions p, and the body part B of the cabinet is held in place bya bail q, having its ends secured to the top plate D, and its loop engages one or the other of the projections 19. By moving the loop of the bail laterally it is disengaged from the projection 19, and this allows the part B to be lifted clear of the base and to expose the burners for cleaning or other purposes. The top plate is provided with the usual openings provided with gratesections r.

The reservoir I have improved by securing to it a handle of bail form, as shown at S, the ends of the bail having pivoted connection The rectangular shape of the with the side walls and secured thereto at a greater distance from the top of the reservoir than from the bottom. When the reservoir is in position within the oil-chamber o, the handle swings under the oil chamber, as shown in Fig. 1, not only out of the way, but serves also to prevent the accidental displacement of the reservoir. Then it is desired to remove the reservoir for filling purposes, the handle is lifted and with it the reservoir, which immediately turns upon the handle to an inverted position, with the filling orifice uppermost, this action being caused by the position of the pivoted ends of the bail in relation to the bottom and top of the reservoir. This makes a very convenient form of reservoir. The oil -chamber 0 is strengthened by two brace-pieces 15, extending from side to side of its inner walls.

The burners comprise an oil-holder in the shape of a cup 2 of a greater depth than width and of angular shape, and surmounting the cup is a combustion-chamber composed of perforated tubes for feeding air to the flame. The oil-holder is provided with an igniting medium, of asbestos or the like, though this is not essential. The burner is supplied with oil through a T-pipe, as shown in my former patent, the vertical part of the T having a sliding connection with the pipe h. The cup or oil-holder has its lowest point where it connects with the cross-bar of the T-pipe, so as to be readily drained. The burner is moved upland down across a maintained oil-line to lower or raise the flame, as may be found necessary or desirable. The up-and-down movement is imparted to the burner by a very simple mechanism. The pipe 71. is provided with two grooves 33, and a bracket 4:, made of two parts clamped together, fits around this pipe, with projections entering the grooves, and thus the bracket is not only properly seated, but accurately, and there is no danger of slipping. A rack 5 of the shape shown fits around the horizontal part of the T-pipe by means of a hook at its upper end, while the toothed part extends vertically. A lever 6 has a toothed inner end 7 of segmental shape engaging the rack, this lever being pivoted on the bracket, as shown. On the side of the bracket I secure a casting of the peculiar shape shown in Fig. 4. It is secured to the bracket adj ustably and serves to limit the upward movement of the cup, to indicate the height of the oil therein, and to tilt the combustion-chamber for igniting purposes, while at the same time this enables an unskilled person to readily adjust the cup as to its extent of movement, so as to cause it to more readily flood in case the first adjustment was not perfect. This casting (shown at 7 is made symmetrical at each end, so as to be interchangeable and reversible, and thus capable of use on the right-hand side of one "casting and the left-hand side of the other. This casting 7 has a central slot which permits it to be secured to the bracket and to be adjusted thereon. It has a vertically-extending pointer 8, which in the raising and lowering of the oil-holder indicates the depth of oil in the bowl. A projection 9 extends rearwardly .to immediately in rear of the rack 5, having a turned-in end, and this is in the path of a stop 9 on the rack, thus limiting the upward movement of the burner. When the burner is lowered, the lower edge of the cup rests in the fork 10 of the casting 7, its movement being thus limited downward, and at the same time the end of the projection 9 strikes the bottom 9 of the combustion chamber (shown in dotted lines in Figs. 1 and 2) and tilts the combustion-chamber on its seat on the oil-cup, thus exposing the front edge for igniting purposes.

The door of the part B preferably swings downward, being hinged at the bottom, and it has two vertical slots to allow the handles 6 of the operating-levers to project, so that they can be operated from the outside without opening the door. An indicator on the door shows where the pointer 11 on the han- (ile should be in the various positions,whether for lighting, high flame, low flame, or put out. The handles 6 of the operatinglevers are pivoted to the bracket 4, which has swiveled connection with the pipe 71, and hence when it is desired to lift off the cabinet the door is swung on its hinges and the levers turned inwardly, as shown in Fig. 1, the bracket swiveling on the pipe h.
