6 'Claims.

The invention relates to tops for stoves and more particularly to a pressed steel top for a sheet metal heating stove.

An object of the invention is to produce a one- 5 piece pressed steel stove top having integral drawn collars therein for attachment of the firing door and the stovepipe.

Another object is to provide a simple, inexpensive and easily attached hinge for the firing 1O door. 7' A further object is the provision of a lining to the outside and/ or inside of the stovepipe collar.

The above objects, together with others which will be apparent from the drawings and follow- 15 ing description of which may be later pointed out may be attained by constructing the improved stove top in the manner illustrated in the accompanying drawings, in which Figure 1 is a plan view of the blank from whic 20 the improved stove top is made;

. Fig. 6, a fragmentary sectional view showing the manner in which the firing door is hinged to the fuel collar;

Fig. 7, a detached perspective view of the improved hinge before the same is inserted into the door and collar; and

Fig. 8, a perspective view of a stove provided with the improved top.

Similar numerals refer to similar parts throughout the drawings.

The improved stove top to which the invention pertains is adapted for use upon a sheet metal wood-burning heater, as indicated generally at I!) in Fig. 8. Stoves of this character are provided with a draft regulator as indicated at H, which may be located upon the body of the stove or upon a door l2 upon an ash pouch I3 as illustrated.

The top M is ordinarily flat and formed of sheet metal having a fuel opening surrounded by a collar l5 and covered by a firing door l6 and a stovepipe collar "which in general practice are formed of separate pieces of metal attached to the top of the stove.

The present invention contemplates the provision of a drawn steel top, of heavier gauge than the remainder of the stove and having integral collars surrounding the fuel opening and stovepipe opening.

In producing the improved stove top, the steel sheet from which the same is to be made is first 5 normalized, after which the blank shown in Figs. 1 and 2 is stamped therefrom having the opening lfia of considerably smaller diameter than the fuel opening collar to be formed at. this point and the opening I'm of considerably 10 less diameter than the stovepipe collar to be formed at this point, the opening Ha being surrounded by the spaced concentric rib iii of a diameter substantially the same as the finished g stovepipe collar to be formed.

The blank thus formed is then placed in suitable dies having means for engaging the rib 18 to prevent displacement of this portion of the blank during the drawing operation and the stovepipe collar I! is drawn upward in cylindric 20 form, as best shown in Fig. 3 and may be provided at its upper edge with the rim bead [9. The fuel opening collar is drawn upward and inclined as shownat 15 and then downturned and substantially straight as shown at 211. Slots 2| are formed in the inclined portion l5 and sub stantially straight portion 20 of the fuel opening collar for attachment of the hinge for the firing door it, as will be later described.

It has been found by experience that in this deep drawing of the stovepipe collar H, the upper open end thereof is occasionally torn or split and in order to cover up this damaged upper end of the stovepipe collar so as to improve the looks as well as to reinforce the same, a lining may be provided for the inside of the collar as shown in Fig. 4, this lining being formed of a strip 22 of light gauge sheet metal of suitable length and width which may be located within the collar I! as shown in Fig. 4, the lower edge of said strip being bent outward forming an angular flange 23 against the lower end of the collar I? and the upper edge of the strip 22 being beaded over the open upper edge of the collar l1, covering and reinforcing the damaged portion thereof.

If desired, a lining may be provided upon the outside of the collar I! as shown in Fig. 5, in the form of a light gauge strip 25 which surrounds the collar, the bead 24 being formed over the upper edge thereof. This outer collar covers any imperfections which may extend downward some distance from the upper edge of the collar IT.

The hinge provided for attaching the firing door l E to the collar surrounding the fuel opening may be formed of a single piece of sheet metal as shown in Fig. 7, the metal being bent substantially half-round at a point spaced from one end, as indicated at 26, one end portion 27 of the hinge being preferably of considerably less length than the other end portion 28.

In order to attach the hinge, the

ends

27 and 28 may be bent toward. each other with the fingers, the shorter end 2'! being inserted through the slot .29 located directly above the rim bead 29a of the door IS, the curved portion 26 of the hinge being located around said rim bead. The two ends 2'! and 28 may then be squeezed tightly together and inserted through the slots 2| in the the body of the stove. and reinforces the upper portion of the stove and fuel opening collar and bent downward as shown at 3'3 in Fig. 6, the terminal portion of the long end 28 then being bent backward below the edge of the straight portion 2e of the collar as indicated at 3 i. This forms a very simple, inexpensive and easily attached hinge for hinging the firing door to the fuel opening collar.

Another feature of the improved stove top is the formation of the downwardly curved edge 32 having the recess 33 formed at its lower end and terminating in the flange 34 adapted to be seamed to the upper edge of the side wall it forming This greatly strengthens slightly less depth than the collar and terminating just above the level of the stove top, a firing door arranged to seat around said tapered collar, and a hinge for the firing door whereby the door is arranged to be swung upon a horizontal pivot.

2. A sheet metal stove top having an integral, cylindric collar formed therein for the attach- P ment of a Stovepipe, there being a fuel opening in said stove top and an integral collar surrounding said opening, said collar being upwardly and slightly inwardly tapered and terminating in a downturned substantially cylindric flange of slightly less depth than the collar and terminating just above the level of the stove top, a firing door arranged to seat around said tapered collar, and a hinge for'the firing door whereby the door is arranged to be swung upon a horizontal pivot.

3. A stove top having a fuel opening therein and a collar surrounding said opening and being upwardly and slightly inwardly tapered and terminating in a downturned flange, there being registering slots through the upturned portion and downturned flange of said collar, a firing door for said opening having a flared lower edge portion arranged to seat over said tapered collar and having a slot near its edge, and a hinge formed of a single strip of sheet metal bent upon itself intermediate its ends and having one end portion located through the slot in the door and both ends located through the slots in the collar and bent angularly downward against said flange whereby the firing door is arranged to: be

swung upon a horizontal pivot.

4. A sheet metal stove having a fuel opening therein and an integral collar surrounding said opening and being upwardly and slightly inwardly tapered and terminating in a downturned flange of slightly less depth than the collar and terminating just above the level of the stove top, a firing door for said opening having a flared lower edge portion arranged to seat over said tapered collar, and a hinge for the firing door whereby the door is arranged to be swung upon a horizontal pivot.

5. A sheet metal stove having a fuel opening therein and an integral collar surrounding said opening and being upwardly and slightly inwardly tapered and terminating in a downturned and slightly inwardly tapered flange of slightly less depth than the collar and terminating just above the level of the stove top, a firing door arranged to seat around said tapered collar, and a hinge for the firing door whereby the door is arranged to be swung upon a horizontal pivot. 6. A sheet metal stove top having its peripheral portion curved downward and outward and then formed outward and upward forming a peripheral channel around the edge portion of said stove top, and terminating in an angular attaching flange adapted to be downturned for connection to the body portion of a stove.
