TOASTER ATTACHMENT FOR CAMP STOVES Filed May 8, 1961 2 Sheets-Sheet 2 I PATENT AGENT United States Patent Ofifice 3,062,127 Patented Nov. 6, 1962 3,062,127 TOASTER ATTACHMENT FOR CAMP STOVES Robert A. B. Lang, 340 McNab Ave., Renfrew, Ontario, Canada Filed May 8, 1961, Ser. No. 108,678 Claims. (Cl. 99393) This invention relates to a toaster attachment for camp stoves.

Many attempts have been made in the past to provide an attachment for making toast in conjunction with gas burners such as are employed in camp stoves. However, none of such attachments are in widespread use largely because, it is believed, they fail to produce satisfiactory results or because they are unwieldly and awkward in operation.

It is an object of this invention to provide a toaster attachment for camp stoves which is simple and inexpensive in manufacture, which is compact in form for ease of storage and handling, which is subject to easy erection for use, which may be employed to produce toast of high quality, and which is readily adaptable for incidental uses.

The invention will be described with reference to the accompanying drawings, in which FIGURE 1 is a perspective view of a camp stove with the attachment of the present invention associated therewith,

FIGURE 2 is a partial perspective view of the camp stove showing use of a portion of the attachment as a hot plate,

FIGURE 3 is a perspective view of one part of the attachment,

FIGURE 4 is a perspective view of another part of the attachment,

FIGURE 5 is a perspective view of the attachment in disassembled relation for packing or storage,

FIGURE 6 is an elevation of one end of the attachment,

FIGURE 7 is an elevation of the other end of the attachment, and

FIGURE 8 is a perspective view of the attachment in another position thereof for use as an oven.

Referring to the drawing, 1 is a conventional camp stove having a casing 2, a primary gas burner 3, a secondary gas burner 4, a grid 5 overlying the burners and composed of longitudinal rods 6 and transverse rods 7, and a gasoline supply tank 8.

The attachment of the present invention is indicated generally at 9 and comprises two closely similar parts 119 and 11 formed of suitable sheet metal.

Part comprises a substantially flat rectangular main wall 12 and

flat side walls

13 and 14 extending perpendicularly from the side edges of the wall 12 to form a channel-shaped structure substantially U-shaped in crosssection. The wall 12 has a free bottom edge 15 and a free top edge 16. Wall 12 has a relatively short slot 15a extending perpendicularly from the bottom edge 15 thereof adjacent side wall 13. Side wall 13 has an end edge 18 extending angularly from its junction with bottorn edge 15 of the main wall and an end edge 19 extending angularly from its junction with top edge 16 of the main wall. Side wall 13 has a free longitudinal edge 20, a slot 29a extending inwardly from edge 18 and an inwardly offset shoulder 22 adjoining edge 20.

Side wall 14 has an end edge 23 extending angularly from its junction with bottom edge 15 of the main wall and an end edge 24 extending angularly from its junction with top edge 16 of the main wall. Wall 14 also has an inwardly oflset shoulder 25 adjoining its free longitudinal edge 26 and a slot 26a extending inwardly from such shoulder.

The

end edges

19 and 24 are flared inwardly to form

flanges

27 and 28. Preferably, also, the top edge 16 of the main wall is flared slightly outwardly at 29.

Moreover, a reinforcing and protective baffle 30 is desirably mounted on the inner surface of main wall 12 along the bottom edge 15 and in slightly spaced relation to such inner surface. It will be observed that the baffle is slotted at 31 to correspond with slot 1511.

Part 11 is very closely similar to part 10 and has corresponding elements including main walls 32,

side walls

33 and 34, bottom and

top edges

35 and 36 of the main wall, slot 35a, end edges 38 and 39 and longitudinal edge 41 of side wall 33, slot a and shoulder 42 in side wall 33, end edges 43 and 44 and longitudinal edge 45 of side wall 34, and slot 45a and shoulder 47 in side wall 34. Part 11 also has an outwardly flared portion 48 of main wall top edge 36 and a protective bafile 49. However, the

longitudinal edges

40 and 45 of the side walls are not flanged. Moreover, the distance between

side walls

33 and 34 is shorter than the distance between

side walls

13 and 14 by approximately twice the thickness of the metal sheet forming such walls whereby part 11 may nest within part 10 with the outer surfaces of its

side walls

33 and 34 in engagement with the inner surfaces of

side Walls

13 and 14 of part 10.

As clearly shown in the drawings, the

flanged edges

19 and 24 of part 10 and the corresponding edges 39 and 44 of part 11 extend at an acute angle to the plane of the corresponding main wall 12 or 32. Thus, par-

ts

10 and 11 may be associated together, as shown in FIG-

URES

1, 6 and 7 to form a generally pyramidal casing with the

flanges

27 and 28 acting to retain the parts in such association. It will be apparent that the casing forms a chamber with a widely flared bottom opening and a narrow slotlike top opening which is indicated at 50.

Mounted on the outer surface of each main wall 12 and 32 is a bread-receiving grill 51. This grill may be fixed to the wall in slightly spaced relation thereto and is provided with a lower bread supporting shelf 5-2. As shown, the grill may be removably mounted on the wall for ease of manufacture and storage and swingable for convenience in use. To this end, a rod 53 carries the grill and may be mounted on the wall by means of a pair of lugs 54 on the wall. A handle portion 55 on the end of the rod permits swinging of the grill. Parallel heat-dissipating discs 55a may be provided on each rod 52 adjament handle portion 55.

In use, the attachment is erected in the form shown in FIGURE? 1, 6 and 7, and is placed over the primary burner 3 of the stove, as indicated in FIGURE 1. It is firmly positioned on the grid 5 by reception of a longitudinal rod 6 thereof in slots 15a and 35a and transverse rods 7 in

slots

20a, 26a and 40a, 45a. With the burner in operation, toast may now be produced.

It is important, for the purposes of the invention, that a venturi type of chamber be formed over the burner whereby the flame therefrom uniformly heats the main walls 12 and 32 of the device. As a result, the toast produced is of uniform high quality.

When not in use, the parts It) and 11 may be nested, as shown in FIGURE 5, with the main walls 12 and 32 in abutting relation. In this position, the attachment is readily receivable in the main stove casing 2 for storage purposes. This is an important advantage in providing means for transporting the attachment while ensuring that it is always conveniently available for use.

The attachment is useful for other purposes in association with the stove. Thus, as shown in FIGURE 2, one part 11 (or 10) may be fitted over the secondary burner 4 and positioned thereon by reception of a rod 6 in

slots

40a and 45a and main wall 32 overlying the burner. It

spears? may thus be used as a warming plate for reception of a pan or plate which would be supported in spaced relation to wall 32 by the protruding edges of the lugs 54 and the edge 36.

As shown in FIGURE 8, the parts it and 111 may be associated together with the :

side walls

13, 14 and 33, 34 in lapped relation and the main walls 12 and 3 2 in parallel, spaced relation to provide an open-ended warming oven 56. As shown, wall 32 of part 11 rests on edge 20 of wall 13 of part 10, while edge 45 of wall 34 of part 11 rests on wall 12 of part 10. The device in this position is simply laid upon the grid 5 overlying the secondary burner 4.

There has thus been provided a practical accessory for a camp stove which has useful and effective utility and which is highly convenient in operation.

The device may be readily handled when hot by providing hook-receiving holes 57 in the main walls 12 and 32.

It will be understood that by the expression gas burner is intended to mean any burner that employs any form of combustible gas or vapor.
