HOT-AIR STOVE.

Specification of Letters Patent.

Patented July ill, 1916.

Application filed May 10, 1913. Serial No. 766,775.

To all whom it may concern:

Be it known that I, THOMAS WVARREN MIL- LER, a citizen of the United States, residing at VVaukon, in the county of Allamakee and State of Iowa, have invented certain new and useful Improvements in Hot-Air Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hot air stoves, and more particularly to stoves provided with a safety shield or screen.

One of the objects of the invention is the provision of a stove provided with a safety shield adapted to be supported by the base of the stove and to surround the body of the stove in spaced relation thereto.

Another object of the invention is the provision of a stove provided with a safety shield formed of a section of wire screen having its edges reinforced by a metallic frame provided with fastening devices for securing the shield upon the stove.

A further object of the invention is the provision of a stove provided with a safety shield formed of a section of wire screen 1 having its edges reinforced by a metallic frame, the screen and the frame being provided with recessed portions for surrounding the respective fuel door, draft door, and stove pipe openings of the stove. And a further object of the invention is the provision of a stove having a safety shield so arranged thereon that the liability of injury to a person or to inflammable material coming in contact with the stove is obviated, while at the same time the proper radiation of the heat and the circulation of air around and about the heated surface of the stove, is not interfered with.

WVith these objects in view the invention consists of an improved construction, arrangement and combination of parts of a safety shield or screen and hot air stove, which will be hereinafter fully described and afterward specifically claimed.

In order that the construction and operation thereof may be readily comprehended I have illustrated some approved embodiments of my invention in the accompanying drawings, which I will now proceed to fully describe, and having reference to said drawings, in which 7 Figure 1 represents, in front elevation, a stove provided with a safety shield in accordance with my invention, Fig. 2 represents one form of stiffening rim for my improved shield, Fig. 3 represents in elevation one-half of the shield which is constructed in accordance with a modification of my invcntion, Fig. a represents one of the strips used, said figure being a top plan view of the construction of strips shown in Fig. 3, Fig. 5 represents a front view of a shield for application to a stove having a coaldoor, Fig. 6 represents a rear view of a shield applicable to a stove having a stove pipe opening formed in the rear side thereof, and, Fig. 7 represents one means for securing the edges of the wire screening together.

Like reference characters, mark the same parts whenever they occur in one or more figures of the drawings.

Many persons, both children and adults, have been seriously burned by accidentally pressing against stoves or other heat radiating bodies and many confiagrations have occurred by the clothing of persons, or other inflammable material, accidentally coming in contact with such bodies, and it has long been a desideratum to provide some means for the prevention of these catastrophes. After much experiment and extended thought I have conceived and constructed what I consider to be a perfect preventive for any such accidents and at the same time which will not in any wise interfere with the functions of the heat radiating devices.

Owing to divergence in the size, shapes and forms of such heat radiating devices, including stoves, I have found it necessary to modify the construction of my safety shield to suit the circumstances. Some stoves being of top feed design and cylindrical shape, require a cylindrical safety appliance and may or may not require the provision for a door, such as an ash-door or a coal-feed door, and if a stove has a stove pipe projecting from the side provision must be made to accommodate this projection also. With a view to meeting all these possibilities I have constructed the device illustrated in the drawings, in Fig. 1 of which 1 frontof the stove. The top of the netting, in this instance, i's provided with a circu- V larly bent strip 16 to which the upper end of the wire of'the netting is secured. This be formed in an integral frame structure,"

if so desired. The shield is mounted to surround the stove at a suitable distance there- L from and is supported on theb ase of the 15.

stoveby a circularly bent metal strip 15 secured'inan y suitable manner to the bottom of the nettin'g, the reinforced side edges of the shield overlapping each other at the wire netting may consist of any conventional 1 weavebut'is shown in the drawings as comprising ,transversed strands 14? and longitudinal strands 14 The overlapping side edges of'the netting 14 are reinforced by metal strips, as ind ':cated' at 17 ,"one of the strips, however, overlying the other, and being secured together by ,rivetsor bolts 18. These strips 17 extend downwardly nearly to the ash-door where theyare secured to inverted L-shaped strips 19: which surround a cut-out portion of the netting and are secured to the bottom strip 15. i To provide for the coal-feed door,

a portion of the netting'will be cut away as T at 20, in Fig. 5, and said opening in the "netting will be edged or surrounded with thefsubstantially E-shaped metal strips 211 secured thereto by rivets 22, bolts, or the like and in lieu of the strips 17, the outer of which is shown in Fig. 1, central strips '23 and 24- being provided on the meeting edges of the netting 14:, superposed upon each other in a manner similar to the strips 17, and secured together by rivets 25 or the like, and also to the binding strips 21 of theo'p'ening 20, by means of rivets 26 or like fasteners, the upper ends of strips 23 being secured to the top strip 16, and the lower ends of the strips 2 1 being secured 'F'ig. 1.

.20 is fastened to the edges of the wire "21 of the. opening,

The door 20 has the metallic frame 20 around the edgesthereof to correspond with the metallic strips 21 which border and reinforce said opening. This metallic frame strands which compose the body of the door the same as does the screen, and hinges 20 i connect one side of the metallic frame 20 of the door with 'one of the metallic strips 4 and likewise the latch 20 connects the other side of the frame 20 withthe opposite metallic strip 21. This arrangement provides a reinforced door and door seating within the opening 20 and with the door lying flush with the reinforcing strips 21 of the door opening 20.

lVhen it is desired to accommodate a stove pipe, the rear central portion of the netting 14 is provided with strips 27 and 28, as in Fig. 6, which are secured to the netting 1 1 by rivets 29 or other suitable securing means and at their inner ends are secured by rivets 30 to a ring or circular strip of sheet metal 31 surrounding an opening32 formed in the netting through which the stove pipe may pass, the outer ends of the strips 27 and 28 being secured to the top strip 16 and the bottom strip 15 respectively.

'The netting for an ordinary stove may be made in a single piece and joined at its edges in the manner described in reference to the construction of Figs. 1, 5 and 6, or it may be desirable at times to make the shield of separate and detachable semi-circular sections, as shown in Fig. 3. In this instance a strip 32 binds the top edge of sufficient netting to extend half way around thestove to be shielded, while a front strip 33, and a rear strip 33, either integral with or secured to the top strip 32, are secured in like manner to the respective side edges of the netting 34, said front strip being continued in an inverted L-shaped angular form as at35 and 36 to accommodate one-half of an ash-door and being further continued in the form of a bottom strip 37 to the rear strip 33. In making up these sections the angular portion 35 and 36 and the binding strips 32, 33, 33 and 37 may be made integral with the other strips or may be made separately therefrom, but I prefer, in this instance, to form the strip integral. In any event all of the strips are properly secured to the edge of the netting and the strips 33 and 33 along the meeting edges of the netting are provided with holes 38 so that when two of these semicylindrical structures are brought together and their edges overlapped,suit able rivets orbolts maybe inserted through said holes and the sections thus secured together in cylindrical form, sub- 7 stantially as shown in Fig. 1, the method to the. inverted L-shaped strips 19 as in of securing being illustrated in. Fig. 2, securing bolts or rivets being designated 39 and the strip illustrated being two sections of top strip, as shown in Fig. 3, the strip illustrated in Fig. 4 being the same but being shown detached.

While the sectional shield, above described and shown in part in Fig. 3, is formed 7 in sections of wire netting reinforced with an' integrally formed frame structure, and is designed for a stove of the top feed type having a draft opening, the shield may be provided with a door and door opening. This is accomplished by cutting away a portion of the screen 3 1 of each section, in a manner indicated at 20 in Fig. 5, reinforcing the cut away portion of each section with a substantially lE-shaped reinforcing member, indicated at 21 in I i g. 5, which reinforcing members form an integral part of the overlapping strip mem bers 83 of the respective sections, and supplying the door opening thus formed with a door similar to the door 20 of Fig. 5. In addition to the door opening, the sectional shield may also be provided with a stove pipe opening, similar to that indicated at 32 in Fig. 6, by forming substantially semicircular cut away portions in the rear continguous edges of the screen 34L of the sections, and reinforcing the cut away portions at each side of the stove pipe opening thus formed with substantially semicircular reinforcing members which form an integral part of each of the rear overlapping strip members 33 of the sections, each of the semicircular reinforcing members for the stove pipe opening being substantially equivalent to half of the ring member 31 shown in Fig. 6.

While the constructions described cover the experiments which I have made at this time, I desire it to be understood that the invention is not to be confined to these forms, especially as variations may become advisable or necessary in specific instances. The shields may be built with the stoves or they may be secured to stoves already built. When it is desired, in shipping separately from the stoves, it will be of decided advantage to so construct the shield as to permit it to be placed in a flat crate or bundle. Hence I would vary the construction to meet this requirement. Instead of fastening the two edges which meet perpendicularly in the manner described, the meeting edges could be bound on the edges with a metal strip, of lJ-shape or equivalent form in cross section, and having afliXed to one edge of the strip suitable eyes, as at 40 in Fig. 7, which would be engaged in openings 41, through which eyes a rod might be passed to secure the edges together, such 'astening means being applicable to either two, three or four section shields, as might be desired.

Provision will be made in my shields to accommodate any projections or opening of a stove not hereinbefo-re mentioned, such for instance as draft dampers, sliding doors or the like, within the scope of the invention, which is intended to be applied to any and all various forms of stoves and heating devices now in use or which may hereafter come into use.

Ordinarily the shield would probably be placed about two inches from the heat radiating body, but experiment has determined that it is possible to place it within an inch of the surface of the heating body, without injuring clothing, inflammable material or the person, on account of the nonheat absorbing qualities of the wire shield itself, and the circulation of air between the wire and the heating body.

Among the many advantages which I claimfor my construction may be named the following: It occupies no floor space save that required by the stove. It offers no hindrance when giving the stove attention in the way of charging with fuel or removing ashes. Being attached to the stove or resting on the stove base or foot rests, the use of posts or standards and the consequent fastening to the floor is obviated which fastening with screws on an uncarpeted floor would render same unsightly or whenever it became necessary to make such fastening through a rug or carpet, injury would result. It offers no hindrance when changing position of stove, removing, setting up or taking down. Permits one desiring warmth to take a position equally close to a stove so fitted as would be the case with a stove not fitted with the appliance. It offers nov hindrance whatsoever when sweeping, cleaning, or dusting about the stove. Enhances the appearance of the stove. Being in effect a part of the stove or an appliance therefor, liability of lack of adjustment is overcome as might be the case were posts or standards employed. Owing to non heat absorbing qualities of the woven wire there is obviously no radiation therefrom, which permits the appliance to be placed very near the stove body and still affords protection to the person or clothing. The form or shape of the appliance may be made to conform to the form or shape of the stove or ornaments thereon without rendering the appliance less ethcient.

My device envelops the entire stove body, that is from bottom of firepot to top rim, and therefore, it follows that no injury to a child, invalid or aged person could result from falling against or over the appliance as might be were protection afforded by a contrivance not so constructed or designed.

, Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. The combination with a stove and the base thereof, of a screen having its edges reinforced with a metallic frame, said frame comprising upper and lower horizontal members, and vertical members, the lower horizontal member supporting the shield upon the base of said stove, said vertical members provided with means for surrounding the respective openings of said stove, and fastening means upon said vertical members for securing the same in lapped relation for retaining the shield upon said stove.
