To all 'whom t may concern.'

Be it known that I, RUDOLPH HOFFMAN, a Citizen of the United States, residing at Kankakee, in the county of Kankakee and State of Illinois, haveinventedf certain new and useful Improvements in Oil-Stoves, of which the following is a specification.

The invention relates to2 `oil stoves and more particularly to improved means fory mounting the oil reservoir thereof, the aim being to mount the reservoir in such a manner that it will be securely held in place and at the same time may be quickly and easily removed for filling or other purpose.

In the accompanying drawings, wherein I have illustrated a preferred embodiment of the invention, Figures 1, 2 and 3 are fragmentary top, side and end views, respectively, of a stove having a reservoir mounted thereon in accordance with my invention. Fig. 1 is a fragmentary side elevation show- 1 ing the parts swung into position to permit of the removal of the reservoir. Fig.V 5 is a fragmentary vertical section taken on line 5-5 of Fig. 3. Fig. 6 is a horizontal section taken on line 6-6 of Fig. 5. Fig. 7 is an enlarged fragmentary sectional view taken in the plane of lines 7 7 ofV Fig. 6.

Fig. 8 is an end view of the stove top showy ing a detail of construction.

In the drawings 1 indicates a stove frame having a top 2. 3 is a reservoir in the form of a glass bottle, and 4 is an oil well with which the reservoir normally communicates and from which leads an, oil feed pipe 5. The reservoir yis detachably secured toa pivoted frame. 6, and an extension top '7 is mounted so as to swing into position to permit of the easy removal of the reservoir from said frame when the latter is swung with the reservoir into the position shown in dotted linesin Fig. .4."

To support the reservoir 3, the oil well 4, and associated parts upon the stove, I provide at one en d a bracket which may be formed by a pair of side platesy 8 spaced apart and connected by a top plate 9 (Fig.

5). Said top plate has an aperture 10 therereservoir a valve `member 12 in the neck 11 is held in its open positiony againstthe actionk of a' spring 13 by a stem 14 engauing with the toaon` of thewen 4 (Fig. i). said spring bears between a cage 15 entered with-l in the neck and having a portion fixed` to the outer periphery thereof, and a seat for the valve member `12 is formedfby ashallow cup or plate 16 rigid with the vcage'15 andhaving an Opening 17 therein through which the valve stem depends. It will b e seen that when the reservoir is ysupported in its normal Osition, the Oil will flowinto Vthe well 4,

to a eight determined by the pressure of the atmosphere upon the surface of the oil in the Well. From the well the oil is conducted to the stove burners (not shown) by means of the feed pipe 5. n

The frame 6, to which the reservoir is detachably secured, is in the form of a flat plate havlng downturned flanges 18 at each slde edge. Said flanges are pivoted at 18 to the outer ends of a pair of links 19 the inner ends of which are slidably connected to the bracket plates 8 as by means of a cross pin 20 (Fig. 6)-I operating kin slots 21 in said plates. Whenin normal position, the frame is arranged torest upon the top plate 9 o'f the bracket with the side anges 18 depending along the sideplates 8 (Fig.

3 and ldotted lines Fig. 6). For receivingv the neck of the reservoir,y the' frame has a central rearwardly opening slot 22 (FigQG) ofa width less than the diameter of the plate i from the slot.

Normally, the extension top is arranged to lprevent the upward swinging movement of the reservoir, and to permit of such movement and hence the free removal ofthe reservoir, the extension top 7 is swingably mounted as for example upon the' reservoir supporting bracket; and in order thatcthe flow'of oil from the reservoir into the oil and well i shall be pr'omptly cut off by the valve member 12, in the removing operation, said connected by links 25 to the links 19 slidably.

connected to the bracket. The links 25 are provided with stop lugs 25a 6).on their rear side edges adapted to limit the swinging movement thereof relative to the arms 23 in one direction. r

The parts are so arranged that as theeX- tensionY top is swung downwardly from the position shown inFig. 2te that shown in Fig. 4i, the links 19 and thereby the frame 6 are first swung upwardly and then moved forwardly until stopped-by. the pin 2O engaging` with the forward ends of the slots 21. The frame Gand reservoir 3 Vmay then be swung forwardly and downwardly into inverted position.4V To limit such swinging movement of the frame, l provide at each side edge thereof at its forward end a pair of stop lugs 26 formed by bending the` forward edge of the top plate of the frame, slightly widened at thisl point, upon itself as shown at 27 (Figs. 5 and 6). These lugs,

. as the frame is swung downwardly, engage with the lower edges of the links 19, (as shown in dotted lines Fig. 4) and thus limit such swinging movement of the frame, the arrangement preferably being such that the reservoir may finally rest upon the inner end of the extension top 7 as shown in Fig. 4. F rom such position, it will be` apparent, the reservoir is free to be withdrawn vfrom the frame as above set forth.

To replace the reservoir in position'upon the stove, it will of course be understood that the reverse operation to that just described takes place, the reservoir being first slid into position with reference to its frame which is then swung into position between the links 19. Thereupon by swinging the extension top 7 upwardly into its horizontal position the frame and reservoir are lowered into their normal position. For holding the extension top in this position, it may be provided with a pair of latch members T adapted to operatively engage with the stove top (Fig. 5); and for preventing the reservoir from swinging out of its proper or normalposition, a stop member 28 isA provided projecting forwardly from the stove frame, being herein made integral with they top plate 9 of the supporting bracket. The latch members may be rigidly secured to the inner sides of the side flanges of the extension top and engage in slots 7h inthe end flange ofthe stove topl 2 (F ig. 8);V The 'extension top while fixed with reference to the arms 23, is adapted to spring sufare not to be limited except as may be neces-v sitated by the state of prior art.
