RUDOLPH HOFFMAN, KANKAKEE, ILLINOIS, ASSIGNOR TO SEARS, IRJOEB UOK AND 00., OF CHICAGO, ILLINOIS, A. CORPORATION OF NEW YORK.

oIL-s'rovn To all whom it may concern:

Be it known that I, RUDOLPH HOFFMAN, a

' citizen of the United States residing at member 11 having an annular flange 12 at its peripheral edge. An opening 13. is pro- Kankakee, in the county of Iiankakee and State of Illinois, have invented certain new and useful Improvements in Oil-Stoves, of which the following is a specification.

The invention relates to oil stoves and more particularly to improved means for mounting the oil reservoir thereof, the aim being to provide means of extremely simple construction and operation for supporting the reservoir of the stove in such a manner that it will be securely held in place but may be quickly and easily removed for the purpose of replenishing the supply of oil or for other purposes.

In the accompanying drawings, wherein I have illustrated a preferred embodiment of my invention, Figure 1 is a fragmentary top plan view of astove embodying the fea? tures of my invention, but with the reser-. voir removed. Fig. 2 is a central sectional view taken on line 22 of Fig. 1. Fig. 3 is a fragmentary vertical section taken on line 3-3 of Fig. 2.

In the drawings 1 indicates a portion of one end of a stove frame having secured thereto a bracket 2, and 3 designates the lower portion of a tank or reservoiradapted to be supported upon the bracket. .4 is an oil well mounted upon the underside of the bracket 2, and 5 is a pipe leading from the reservoir to thestove burners (not shown);

The bracket 2 comprises an upright portion 2 secured to the stove frame 1 as by means of screws 6, and a horizontal portion or ledge 2 projecting outwardly from the frame 1. At the upperend of the upright portion 2 the bracket has an outwardly pro jecting flange 2 against which the reservoir. is adapted to abut and thus be held in its proper position relative to the frame.

T he reservoir 3 may be of any preferred construction. Herein it is shown in the form of a glass bottle having a neck 7 upon the lower end of which is suitably secured an annular metallic member 8 having a bottom 9 with an aperture 10 therein. Secured to said annular member 8 is; acup-shaped vided in the bracket portion 2 -adapted to a d ar-share membe 21 w th. e;

flange 12 resting upon the u per edge of the opens into the bottom of the well near one edge thereofand leads inwardly through the stoveframe l. The pipe thus assists the bracket 2 in supporting the reservoir 3 and associated parts.

When the reservoir 3 is supported in position upon the bracket, oil is permitted to flow therefrom freely into the well. 4, but means are provided so that when the reservoir is removed from its support the flow of oil therefrom is immediately cut off. This means herein comprises a valve member 14 mounted u on a stem 15 and arranged to seatupon 't e edge of the opening 10 in the bottom plate 9 of the annular member 8. A spring 16- bearing between said valve member and a cage 17 entered within the neck and secured to said plate 9 normally tends to seat the valve member 14.. The parts are so arranged, however, that when the reservoir is in its operative position the valve stem engages with the bottom of the well 4 and holds the valve member 14:,against the action ofthe spring 16, in its raised position. The means for securing the reservoir 3 in position upon the bracket 2 preferably comprises a horizontal slide member or sleeve 18. This member is substantially rectangular in form and is adapted to substantially surround the well 1 and horizontal portion 2? ofthe bracket. Thus it comprises a top Said aperture and slot are arranged toper- Init of sliding movement of the member 18 relative to the reservoir 3 and pipe 5; and

the aperture 23 is shaped so that when the member18 is in its innermost or operative position the reservoir 3 is held against removal by the top wall of the member engaging with theflange 12 of the cup-shaped member 11 seated upon the horizontal portion 2 lof thebracket and when the member 18, is moved to its outer or inoperative position, the cup-shaped member 11 may be .nithdtanath eae ithe perture 23', th s end the forward portion of the aperture 23 is made of a size substantially less than the diameter of the cup memberll, and at the rearend of the aperture it is made of a size slightly greater than the diameter of the member 11 (Fig.1). To aflord a convenient hold for the fingers of the operator in oper-.

.atinglthe slide, the forward wall thereof may be extended downwardly below the bottom wall 21, as at 22s.

I As a means for limiting the outward sliding movement of the member 18, I provide 2 a stop member 25 in the form of a strap entered through a slot in the upright portion 2= of the bracket immediately above the hor- 7 portion 25* of the sto member 25, and the parts are relatively arranged so that the 7 forward movement of the member is limited just as the enlarged portion of the aperture '23 comes into register with the aperture 13 (broken lines Fig. 1), upon the edge of which is seated the flange 12 of the cup member 11. In this position of the parts it will be seen that the reservoir may be readily withdrawn upwardly, the cup member 11 passing throughthe enlarged portion of the aperture 23. When the slide is in this position, the portion 25 of the stop member is arranged to engage in a notch 23 formed in the top plate 19 at the rear edge of the aperture 23 '(Fig. 1). To again lock the reservoir in position it will be apparent that it is only necessar i to insert the cup member into place with its flange resting upon the edge of the aperture 13 and then slide the member 18 rearwardly into the position shown in full lines in Fig. 1 when the restricted portion of the aperture 23 overlies the cup 11. In this operation, the stop member 2 5,'-"by reason of the engagement of the flange 12 of the cup member withthe forward edge'of the-hook portion 25 of the stop member. also serves to assist in holding the cup member in position while the member '18 is slid rearwardly. This arrangement is particularly advantageous in the event that the member 11 is so shaped that I it"wil'l'not engage with the edge of the aperture 13 as herein shown.

ee -extremely simple' as is also the construction '-'I'he -operation of removing the reservoir is thereof. An eflicient device is accordingly produced which may be manufactured at a minimum cost.

While I have herein illustrated and described the invention with considerable paropening in said ledge, and a slide member on said ledge comprising a plate having an aperture therein adapted in one position of the member to engage the flange member of: the reservoir to hold it in position and in another position of the member to pass said flange member and to permit the removal of the reservoir.
