OIL-STOVE.

Application filed April12 T all who-m it may concern .3

Be it known that I, RUDoLrH IIOFIPB'AN, a citizen of the United; States, residing at Chicago Heights, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Oil Stoves, of which the following is a specification.

This invention relates particularly to improvements in oil reservoirs for oil-burning cook stoves, ranges and other stoves.

One of the objects of the invention is to provide improved means for relnovablysupporting the reservoir.

Another object is to produce means for preventing undesired relative movement between a reservoir and its carrying bail.

In the accompanying drawings, Figure 1 is a fragmental front elevation of an oilstove embodying the features of my invention. Fig. 2 is a view taken from the righthand side of Fig. 1;. Fig; 3 isa fragmentary vertical sectional view taken in the plane of dotted line 33 of Fig. 1.

In the drawings, 2 designates an end wall of the stove.

3 is a horizontally disposed member which is attached to the wall 2 by suitable means, such, for example, as. a vertical plate l secured to the wall 2. The parts 3 and i may be formed from an integral piece of sheet metal. The member 3 is supported in part by two arms 5 attached at their ends to the outer corners of the member 3 and to the wall 2. Fixed to the member 3 and extending downwardly therefrom is a well 6, the lower end of which communicates with the burner (not shown) through the medium of a feed pipe 7. y

In the embodiment herein shown of the invention, the oil tank 8 is of glass and comprises a cylindrical body 9 having a neck 10. The neck 10 is provided with suitable means for closing it, such as a cap or closure 11 adapted to be screwed onto the neck. The closure 11 has an outlet opening 12 which may be arranged to be closed by any preferred means such as a valve 13 fixed to a stem 14, said stem being guided by a standing loop 15. A spring 16 tends to move the valve 13 into position to close the opening 12. hen the tank is in place, the lower end of the stem 14: rests upon the bottom of the well 6, thereby holding the valve 13 open. When the tank is lifted out of place, the spring 16 seats the valve 13.

Specification of Letters Patent.

Serial No. 20,939.

The tank 8 is arranged to be supported upon the arms 5, the latter being notched to, form sockets as at 17 to receive two diametrically opposite projections on the body 9. These projections may be of any suitable construction; herein I have shown them as each consisting of a flanged sheet metal disk 18 secured by a bolt 19 and nut 20v to a band 21 that encircles the body 9. The band 21 may lie within an annular groove 22 in the body 9, as shown. The body 9 has a recess 9 to receive the head of the bolt 19, said recess being of sufficient size to prevent a blow upon the flanged disk 18 from driving the head of the bolt into contact with the glass. The portion of the band 21 which bridges the recess serves to cushion shocks received by the disk 18. To prevent the band from shifting, circumferentially of the tank, suitable means, may, if desired, be used, such as the interlocking connection herein disclosed consisting of alug 23 on the body 9 projecting into a. cut-out or recess 24: in one edge of the band.

The weight of the tank is carried by the arms 5, swinging movement (to right or left, Fig. 1) being prevented by two lugs projecting from the end wall of the stove into position to touch the body 9 above and below the horizontal plane of the sock ets 17 In the present embodiment the lugs 25 are the angular ends of a bar 26 which is fixed to the plate 1.

27 is a carrying bail having loops 28 that are pivotally mounted on the flanged disks 18.

In the present embodiment of the invention, that end of the tank which is uppermost in Figs. 1 and 2 is the heavier end. To prevent the tank from automatically swinging through a half-revolution when the operator grasps the bail and lifts the tank from its support, I provide the following described means. 29 is a disk having a central aperture for the bolt 19. Near its periphery the disk 29 has a series of openings 30 adapted to receive rounded bosses 31 which are molded on the body 9. The disk 29 is connected to turn with the ball 27 by means of two lugs 32 between which the bail arm lies. To turn the bail and the tank with relation to each other, it is necessary for the disk 29 to spring or flex sutliciently to allow the bosses 31 to pass into and out of the openings 30. The disk 29 and the esj q swung by the operator into position for fill- A disk 29 and bosses 31 may be provided at one or both sides of the tank. Herein I have shown such devices at both sides.

Figs. 1 and 2 illustrate the tank in operative position, the outlet 12 being open, and the well 6 being partly filled with oil. lVhen the user observes that the tank is nearly empty, she grasps the bail Q7 and lifts the tank oil from its supports 5, the valve 13 closing automatically. The operator then turns the tank through 180, unserews the closure 11, pours a quantity of oil into the tank, replaces the closure, inverts the tank and sets it on the arms 5.

I claim as my invention:

1. In an oil stove, a stove frame, a tank having a body and a neck, two diametrically opposite )rojections on said body intermediate the ends oi the body, two supports on the stove fran'ie, said projections resting upon said supports, a well below the supports, the neck of the tank extending into said well, and means above and below the horizontal plane of said projections to prevent the tank from swinging on said supports.

2. In cinnbination, a glass tank having an encircling metal band, two trunnions, bolts securing said trunnions to diametrically opposite parts of the band, a bail having loops surrounding the trunnions, a member pivoted on one of the bolts and lying between the band and the adjacent arm of the bail, the member and the tank being adapted to coact to resist rotation of the handle, and a connection between the member and the bail.

3. In an oil Stove, an oil tank, supporting projections extending from opposite sides of the tank, supports upon which said projections rest, and members above and below the horizontal plane of said projections, said members being arranged to touch the tank to prevent the latter from swinging on said supports.

at. In combination, an oil tank having a trunnion, a handle having a loop encircling the trunnion, a disk mounted on the axis of the handle, said disk and tank having interengaging series of rotation-resisting means, and means to cause the handle and said disk to turn together.

5. In combination, a glass tank having a trunnion on its side, a handle pivoted on said trunnion, a member located near the axis of the handle and arranged to move with the handle, and means on the tank arranged to be engaged by said member to resist pivotal movement of the handle with relation to the tank.

6. In combination, an oil tank, a handle pivoted to the tank, a disk mounted on the axis of the handle, said disk having a circular series of openings, bosses on the tank arranged to lie in said openings, and means to cause the handle and said disk to turn to gether.

' 7. In combination, a glass tank having trunnions attached to opposite sides of the tank intermediate its ends, a bail pivoted on said trunnions, and means resisting pivotal movement of the bail with relation to the tank.

In testimony whereof, I hereunto set my hand in the presence of two witnesses.
