ATTORNEY Patented Nov. .26, 1935 UNITED STATES PATENT OFFICE Pen Application May 15, ms, Sula! No. mace 10 Claims. (01. 125-29) Theinvention relates generally to stoves, and

it has particular relation to a stove for use in parks, or similar places. 7

One object of the invention is to provide an improved park stove which will be more satisfactory and convenient to campers or others enjoying the facilities'of a park, in the preparation of lunches or the like.

Another object of the invention is to provid an improved park stove of inexpensive construction, which is adaptedto become a permanent fixture and wherein various parts of the stove are normally secured against removal.

Another object of the invention is to provide an improved park stove which is so constructed and arranged that a fire may quickly be built in the stove and controlled and utilized in a highly efiicient and convenient manner.

Another object of the invention is to provide an improved park stove in which the undesirable effects of wind drafts may largely be avoided.

Other objects of the invention will become apparent from the following description relating to the drawing, and from the claims hereinafter set forth.

For a better understanding of the invention, reference may be had to the drawing, wherein: Figure 1 is an end elevational view of a park .stove constructed according to oneform of the invention, with certain parts broken away for the purpose of illustrating details more clearly.

Fig. 2 is a plan view of the construction shown by Fig. 1 and also havirg certain parts broken away to show details of the construction.

Fig. 3 15 a cross-sectional view taken substan-- tially along the line 3-3 of Fig. 2.

Fig. 4 is a cross-sectional view taken substantially along the line 44 of Fig. 3.

Fig. 5 is a cross-sectional view taken substantially along the line 55 of Fig. 3.

Referring to Figs. 1, 3 and 4 particularly, the stove illustrated includes-a sheet metal shell l6, having side walls II and I 2 and an end wall l3. Each of the side walls I l and I2 has an outward ly directed flange M at its lower edge to provide a larger supporting base, and theseflanges may be provided with openings l5 by means of which the stove may be bolted to a concrete or other base if this is found desirable.

For the purpose of providing a draft control in the wall i3, the lower portion of the latter is provided with an opening l6 as shown by Fig. 3, and at the upper and lower sides of the opening, oppositely disposed angle irons l1 and I l are secured to the wall, as for example, by spot welding.

These angle irons. as best shown by Fig. 5, provide a guldeway at the inner side of the wall and for adjustably covering or uncovering the opening l6 to control the draft, plate members I9 and 26 are slidably mounted in the guideways. 6

'For adjusting the plates from theexterior of the stove, adjacent edges of the plates have notches 2| for receiving handle portions 22 projecting to the exterior of the stove and which terminate at their inner endsin angular flanges 33 that 10 may be spot welded to the inner side of the plates, respectively. It is apparent that either plate may be moved separately of the other, and that by manipulation of the plates the amount of draft may be conveniently and closely controlled. 16 At their ends opposite the wall l3, the side walls II and I2 terminate, respectively, in sharp, inwardly directed flanges 25 and 26. The lower portion of each of these flanges, as best shown by Fig. 1, is provided with hinge elements 21 and 20 28 that may be welded or otherwise secured to the flange and such hinge elements are apertured for receiving a pintle 29. Such pintles hingedly support a pair of doors 3| and 32 and each door is provided with hinge elements 32 and 33 welded 25 or otherwise secured thereto and which have and slightly offset portion 35 whichpermits over- 35 lapping of the door 3| when the doors are in their closed position and locating their outer surfaces substantially in the same plane. For holding the doors in their closed position, the door 3! is provided with a pivoted latch element 36 projecting 40 through and havingits vertical movement limited by a U-shaped element 31 welded or otherwise secured to the door, and such latch element is adapted to cooperate with an upwardly open keeper 36 weldedor otherwise secured to door 45 32. The outer end of the latch element-has a handle portion 40 for facilitating its-manipulation. For limiting closing movement of the doors, a strip of angle iron 42 extends between and at the inner side of the flanges 25 and 26 of the 50 shell l6, and when the doors reach their closed position, their upper edge portions slightly overlap and abut the vertically disposed leg of the angle iron. This angle iron provides a strong connecting means between the flanges 25 and 26 55 grate is constructed of cast iron. For permitting insertion and withdrawal of the grate whenever thisshould be necessary, each of the flanges 25 and 26 at points in alignment with the channel irons, is provided with a notch 41, as best shown by Fig. 1. Normally, however, the grate is not to be removed except in the event .it becomes broken, and in view of this, the notches 41 in the flanges 25 and 26 may be covered once the grate.

is in position. For normally preventing removal of the grate and at the same time covering the space between the flanges 25 and 26 above the doors, a. cover plate 48 is provided which, at its lower edge, overlaps angle iron 42 and at its side edges, is bolted to the flanges as indicated at 49. Preferably, the bolts employed have nuts on their inner ends so as to render it more diflicultfor anyone to remove the coverplate and thenremove the grate 46. This cover plate may be provided-with any suitableindiciaonitsouter surface, indicating ownership of the stove and it may be preferred to uses. cast iron plate having this indicia cast on the outer surface-thereof. For further reinforcing the flanges 25 and 26 of the shell and hence providing a more rigid construction, an angle iron 50, similar to-angle iron 42, extends between the flanges and is welded to the inner surfaces thereof, adjacent the upper edge of the cover 48.

From the description so far given, it will be appreciated that the lower part of the stove may be cleaned of ashes by opening the doors 3| and 32 and that these doors also may be used forregulating draft through the stove. It also will be appreciated that the draft control in the walll3 will enable convenient and close control of the draft in conjunction with or separately of the doors 3| and 32. It will be apparent that the grate 46 provides a suitable support for the material to be used in making the flre and that upon combustion thereof, ashes or the like will drop through the grate and into the lower part of the stove where they may be removed through the doors 3| and 32.

At the upper edge of the shell l0, andas best shown by Figs. 1 and 3, a second pair of channel irons 55 and 56 are secured as by spot welding to the side walls H and I2 to provide guideways for a pair of upper grates 51 and 58 shown in Fig. 2. These grates, preferably, are constructed from cast iron and are inwardly and outwardly slidable in the channel guideways. For permitting this sliding movement, of the grates, the flanges 25 and 26 are notched in alignment with the channels as indicated at 59 in Fig. 1, and the upper edge of the wall I3 is flanged over inwardly of the stove and under the channel irons as indicated at 66 in Fig. 3. 7

Once the grates are disposed partly -in the guideways, studs, as indicated at 6| in Fig. 3, may be threaded into the center rib of the grate from the under side thereof and at points near their inner ends respectively. These studs are so positioned that entire removal of the. grates is impossible as the studs will engage either the turned vantageous to anyone building a fire on the latter grate. For facilitating movement of the grates 51 and 58, handle elements 63 may be pivotally connected to the outer ends thereof, as best shown by Fig. 1.

The side walls H and I2 at their upper edges are provided with outwardly directed flanges 64 and 65 and each of these flanges has two pairs of hinge elements 66 and 61 welded or otherwise secured to its upper surface. These hinge elements are apertured for receiving a pintle 68 extending substantially the length of the flange upon which they are mounted. Each pintle hingedly supports a pair of lids 10 and H having rib-shaped hinge elements 12 welded thereto and apertured at their ends for receiving the pintle and each lid is disposed between a pair of the hinge elements 66 and 61. The lids may be opened separately and when opened the full amount, the ribs]! rest on the flanges 64 and 65 as the case may be, and in such position that the then upper surfaces of the lids will be substantially horizontal and will be suitable for supporting pots or pans used in cooking. It will be appreciated that the entire upper surface of the grates 51 and 58'may be exposed for cooking with all of the lids open or thatone or more of the lids may be closed leaving one or more open and a correspondingly smaller amount of the upper surface of the grate exposed for cooking. This is advantageous in that the heat ofthe fire on the grate 46 may be more concentrated for cooking in a given area of the upper grate.

In order to avoid the efiects of wind draft, means are provided to secure any or all of the lids in a semi-open position as shown in broken v lines at 16 in Fig. 1. This is accomplished by prolocated in the path of movement of the hinge elements I2 on the lids, if such lids are shifted slightly in one direction longitudinally of the pintles. For example, with the lids in the position shown by Fig. 3, opening of either or all lids will cause the hinge elements I2 to engage the raised projections 14 and I5 upon opening of the lids approximately two thirds and when so opened the lids will be maintained in this position by their own weight. If the lids are shifted longitudinally of the pintles slightly from the positions shown in Fig. 3, they may be opened without engagement of thehinge elements 12 with the projections 14 and li and hence may be fully opened and into their horizontal positions as shown by Fig. 1. Placing either side pair of the lids in the partly open position provides a wind breaker and anyone familiar with the building of outdoors fires will appreciate the advantage of a wind breaker to prevent interference with the fire.

ably, the stove is manufactured in such size that its weight will be sufilcient to prevent any easy removal.

lids-and separating .the upper grates and opening one or more of the draft control'means, a fire may be quickly started on grate 46 and com trolled by adjusting the draft means. The lids in addition to providing convenient supports when they are in fully opened positions, are useful in providing wind breakers on either or both sides when in partly open position, and additionally for covering a variable area of the upper grates so as to obtain a more concentrated heat at the re maining exposed grate surface. It is apparent that the doors 3| and 32 in addition to providing a draft control, provide a ready means for removing ashes from beneath the firegrate 46; Moreover, it will be appreciated that after use of the stove, the lids and draft controls may be closed, to substantially eliminate any fire hazard after users of the stove depart. While the parts of the stove are fixedly connected, any of the parts may be readily replaced whenever this is necessary although normally sulficient difliculty would 'be encountered it removing any part thatthe ordinary camper would not take the trouble to remove it. The construction provided is extremely rigid and strong and will last indefinitely, and actual experience has demonstrated that campers and others interested in preparing outdoor meals find the stove extremely convenient and emcient not only in building and controlling a fire but in the preparation of cooked food.

Although only one form of the invention has been described and illustrated in detail, it will be apparent to those skilled in the art that various modifications may be made without departing from the scope oi the appended claims.
