1 Claim.

This invention pertains to ranges and more particularly and specifically to the method or manner of constructing a range. A coal or Woodburning range is described and illustrated in the drawings to enable an understanding of the invention, but the inventive concept is not limited to a range of this type and is to be limited only Within the scope of the hereinafter following and appended claim.

The present method of constructing a range has many advantages, some of which will be immediately hereinafter referred to while others will appear on a reading of the specific description of the invention.

Ordinarily stoves of the type illustrated and described have in the past been composed of a great number of parts each separately fabricated and then the plurality of parts bolted together in a final assembly. The handling of separate parts, punching of holes and the assembly with lbolts all make for a relatively costly method of manufacture and results in a range the production cost of which, and therefore the sales price, is relatively high.

The present invention has as its primary object the simplification and therefore the cheapening of the production of a range. This is aecomplished in a large degree by making or forming the range parts in such a manner that the entire framework or structural basis of the range can be spot, line, or seam Welded together, after which the assembly can be painted or otherwise finished such as by spraying with various types of lacquer or paint and then baked, if desired.

The accomplishment of the desired result is further attained by substantially reducing the number of parts making up the range and particularly the number of parts comprising the main stove framework or basic structure. The number of parts comprising this portion of the range has been reduced to nine, as will appear 'more specifically from the following specific description of the improved construction.

Enumerating the more important improvements of the invention, a range made in accordance therewith will have a minimum number of parts and will be susceptible of rapid assembly. These attributes will result in the use of less material, thereby reducing the weight of the range and the production of the range with a much smaller labor time expenditure. The resulting range Will have greater strength and will consequently be rigid and non-warping. Additionally the flues of the range will be air-tight and due to there being no restrictions in the ues and to the rounded conguration of the oven improved baking will result along with a saving in fuel. A still further attribute of the range Will be that it will have an improved appearance and can be easily cleaned and kept clean.

In the drawings, which illustrate one embodiment of the invention:

Fig. 1 is a perspective view of the range, a p0rtion of the View being broken away to render the internal construction of the range visible.

Fig. 2 is a longitudinal vertical sectional of the range.

Fig. 3 is a transverse vertical sectional view of the range.

Fig. 4 is a horizontal sectional View of the range.

Fig. 5 is a strung-out perspective View of the nine parts making up the main range framework or structural basis. f

Inasmuch as the construction generally as well as the operation of a Wood or coal burning range is well understood by those skilled in the art, detailed description of such a range is not considered necessary and the following general description will be suiiicient to an understanding.

The range is rectangular in general conguration and has at one end a housing 50 provided with a grate 5| beneath which is a removable ash receptacle or pan 52. At the opposite end the range is provided with a housing or chamber 53 within which is suspended for easy removal, as will be hereinafter described, a hot water storage reservoir 54 provided with a draw-oil spigot, not shown, for removal of hot water as it is desired for use.

, A cooking top is provided and is illustratedas View being composed of a plurality of plates 55 some of which are provided with openings closed by removable lids 56. The manner in which these plates are supported will appear hereinafter. At its rear the cooking top is provided with a vertically extending splash back 5l.

An oven designated as an entirety by A is positioned intermediate the fuel burner and the water reservoir and is suspended so as to provide between its top and the range cooking top a top flue 58, an end iiue 59 and a bottom flue 60.

The direction of travel of the hot products or flue gases is illustrated by arrows, from which it will be seen that both the cooking top and the oven are subjected to and heated by the escaping hot products of combustion generated by the fuel burner.

Referring now to Fig. 5 in which the parts making up the main range framework or structural basis of the range are illustrated, B is a pair of legs, C the range base, D the main body portion constituting the range front I, bottom 2, and back 3 with integrally formed flue 4. A is the oven and is composed entirely of two pieces and 6. A left side flue sheet E and a right side flue sheet F are provided and their positions within the structure appear in the drawings but will be later specifically referred to as will also the bottom flue divider G.

The legs B will be drawn and formed from a single piece of metal and have open tops surrounded by a horizontally disposed flange l.Y

The base likewise will be drawn and formed from a single piece of metal and is of the size and configuration similar to that of the length and width of the finished range. This member is consequently rectangular in form. It has an opening 8 in its bottom and its top is open and provided with an inturned horizontally disposed circumferential flange 9.

The legs and base are welded together. Spot welds are illustrated and are designated as being through the leg flanges at the numerous points l0 and through the base bottom at points similarly designated as III.

The main range body portion D is made of a single piece of metal and has its bottom Welded to the inturned flange 9 at the top of the base. The welding points on the base and on the bottom of the range body are designated at I l. This member in its front I is provided with an opening I2 through which the ash pan or collector 52 may be removed and with an opening I3 which is of the same size and configuration as the open front end I4 of the oven A. The oven opening is provided with an inwardly extending horizontally disposed circumferential flange I5. Beneath the oven opening an opening I6 having an outwardly slanting bottom 16a is provided for cleaning out the flue 69 beneath the oven. An opening I1 is provided to give access to the spigot of the hot water storage vessel or container 54. The flue 4 in the rear wall of this member is provided with an outlet opening I8.

The member I at its vertical edges is provided with an inset I9 and a rearwardly extending flange 20. The longitudinal top edge of the front I is provided with a rearwardly extending horizontally disposed flange 2|. The vertical edges of the rear wall 3 are provided with inturned flanges 22 while its longitudinal top edge terminates in a rearwardly extending horizontally disposed flange 23. The end edges of the bottom 2 are provided with an inset 24, see Fig. 2 of the drawings, and a vertically extending flange 25.

The oven pieces 5 and 6 are each substantially of a U-shape in vertical cross section and each has a plate 26 extending across one end to form a rear end closure for oven. The edges of the tops and bottoms of these pieces are provided with a vertically extending flange 21 which has an extension 28 along the edge of the plate 26. The flanges of the pair of oven members 5 and 6 are placed into abutment and are secured together by spot welds 26 or by a line weld. Prior to fabrication the side walls of each of the oven members are bent to provide over rack supporting ribs 30.

The left flue plate E is of a pan-like configuration and has a circumferential flange 3|. This flue plate is welded at the points 32 to the front, bottom and rear of the main fram@ member D at the points indicated by the numeral 32 on those members.

rThe oven is supported and suspended in proper position as follows: The open front end I4 of the oven telescopically receives the inturned flange I5 of the oven opening I3 in the front wall I of the frame. The flange 33 surrounding the open front end of the oven abuts the front wall I and is welded at the plurality of points indicated at 34. The left side wall of the oven abuts the left flue plate E and is welded thereto at a plurality of points designated 35. 'Ihe rear plates 26 constituting the rear closure for the oven abut the rear wall 3 of the main frame and are welded thereto at a plurality of points 36.

In a range of this type there is usually a bottom flue divider and such a divider is designated G as previously described. This divider is below the oven and in addition to directing the products of combustion as indicated by arrows in Fig. 4 of the drawings the divider acts as a support for the oven. The divider is vertically disposed in the bottom flue 69 and extends from the rear towards the front thereof at an angle. This divider is provided at its top with a horizontal flange 31 and at its bottom with a horizontal flange 38. The horizontal flange 38 rests upon the bottom 2 of the main frame D while its top flange is welded to the oven bottom at the points 39. At its ends the divider is provided with a rear wing 40 and a front wing 4I. The rear wing 4U abuts the rear wall 3 of the range and could, if desired, be welded thereto. The front wing 4I engages the flange 21 of the oven at the points 43, see Fig. 2 of the drawings, and could be welded thereto if desired. Preferably however the divider is welded only to the oven to simplify construction and fabrication.

The right flue plate F defines one side of the vertical flue 59. This plate at its vertical and bottom edges is provided with a flange 44 which is horizontally disposed and is welded at the plurality of points 45 to the bottom, front and rear respectively of the main range frame D.

At its top edge the plate is provided with a horizontally disposed flange 46 which extends oppositely to the flanges 44. Centrally the plater is provided with a bulge 41 the purpose of which will hereinafter appear. It has been said that there are nine parts constituting the structural basis of the range. This is correct when the oven is considered as being two parts. When these nine parts have been assembled and secured together as described the main framework for the range is provided and the rest of the parts to complete the range can be positioned and assembled to provide the complete range illustrated in Fig. 1 of the drawings.

To facilitate the completion of the range the flue outlet opening I 8 in the range back 3 is provided with a flange 62 to which is suitably attached by being welded or bolted the flue boot K which in conformity with conventional practice has its outlet end 63 disposed behind the splash back 51.

A suitable tubular member L is positioned at and extends throughout the length of the front upper edge of the range and throughout the length of its rear face is provided with a flange 64. The front end of the range top plates 55 rest upon a suitable fitting 65 which is supported by this flange. The fitting 65 has a rear portion 66 for supporting the rear edges of these plates and has intermediate portions 61 extending from front to rear of the range for supporting the side edges of the plates.

As will be apparent from Fig. 1 of the drawings the outer side edges of the two end plates 55 are supported on the inturned horizontal flange 68 at the upper ends of the outer end panels M. These panels at their lower ends have inturned horizontal i'langes 69 which rest upon the inturned flanges 9 of the base C and are positioned intermediate this base flange and the bottom 2. These panels will be poreclain enameled and they will be preferably bolted in place. 'I'he aforementioned insets in the basic body piece D permit these panels to be i'lush with the ends of the base C.

The front of the range between the base C and the tubular member L is completed and finished 01T by a plurality of doors constructed in the con.- ventional manner and being procelain enameled. A door N covers the fire box and ash pit openings, a door O covers the oven opening, and a door P covers the compartment containing the water reservoir. A removable panel Q covers the cleanout opening for the ue 60.

As will be apparent from Fig. 1 of the drawings the front wall I of the basic range piece D is inset from the front face of the base C and the front face of the tubular member L. 'I'he aforementioned doors are of the proper thickness so that the front face of the range is flush from the base up to the tubular member L which member extends outwardly so as to slightly over-hang the front face of the range.

From the foregoing description it will be seen that a range constructed in accord vwith the present invention has the numerous advantages hereinbefore enumerated and that a range of pleasing appearance and high eiiciency as well as sturdy can be quickly, easily and more cheaply produced than has been possible heretofore.

Improved baking can be obtained in the oven by reason of the rounded oven which assures unrestricted and smooth flow of the hot products of combustion through the ilues surrounding the oven.

The invention is to be restricted only within the terms of the hereinafter appended claim.
