UNITED. si'ArEs n wenn JACOB E. DAVIS, IRONTON, OHIO.
Application led March 11, 1922. 'Serial No. 542,880.
To LZZ/whomz'tmay/ concern:
Be it known thatl, JACOB E. Drums, a citizen of the United States, and a resident of Ironton, in the vcounty of Lawrence and State of (hio, have invented certain new and useful Improvements in Clay Backs for Gas Heaters, of which the following is a specification.
In gas heaters of the general type about to be described,ithere is provided adjacent the back of the heater a lire resisting clay back formed preferably with a roughened surface so fashioned as to retard the flame and causes it to cling to the :lire back throughout the entire surface thereof. These clay backs function to break up the Haine and retard it thereby causing a secondary miic# ture with the air and produces a hotter Flame.
The roughened surface of the clay back has been usually provided by casting on the clay back lugs or projections in staggered' relation which effectively broke up the flame and distributed it over the clay back. n'moulding these projections on the back they were usually made comparatively thick so as to insure proper strength to the structure and also to insure their being withdrawn with the back as it was taken from the mold.
In practice, these lugs or projections are adapted to become thoroughly heated and radiant, but owing to the necessary size of these projections they do not become radiant and hence the desired visible effect is not produced.
It is therefore, the object of my present invention to provide a clay back with pr'ojections of such dimensions that they may be readily heated and further, to provide 40 means whereby the back together with the projections may be easily and cheaply manufactured. i
In carrying out my present invention construct a clay back with a plurality of apertures adapted to receive the lugs or projections which are formed separately and then inserted in the apertures or recesses formed in the clay back and cemented therein. projections ofers the. possibility `of their breaking easily, l provide openings extending entirely through the clay back and communicating with the recesses wherein repose the projections so that in the eventy a pin becomes broken, the remaining portion may Realizing that the size of these be `ejected from the recess and the same replaced.
Heretofore, it has been the practice toy cast the clay back in one piece, thereby making it necessary to obtain a whole new clay back when one portion ofthe same 'became broken. My present invention contemplates the dividing of the clay back so that one or more sections thereof may bereplaced and eliminating the necessity of replacing the entire back rin case of breakage.
This structure furthermore offers the possibility of forming backs in standardisections whereby the numben of sections may be varied to produce backs of size suitable for different sized heaters.
`With these yobjects in view my'invention consists in the novel arrangement and construction of partswhich will.lOHGmIn'ade` more apparent in the accompanying specification and drawing.
In the drawing: f Fig. lis a vertical section througha gas ieating stove with my invention applied thereto, f' Fig. 2 is a front elevation of the clay back removed,
Fig. 3 is a vertical section taken on line 3-3 of Fig. 2,1V Fig. 4 is a fragmentary sectional view, and, y c y Fig. y5 is a detail persepective' view of. one of the lugs.
In Fig.v l, `I have shown a conventional type ofvgas heating'stove vwhich comprises a body l() formed` with aneopen front 11. The body if) supports a top radiatingplate l2, and a bottom radiating plate 13, both of which converge rtoward the rear thereby providing a supporting means for the clay back. A series of Bunsen burner tubes l5 are supported in a lplate 16 which is suitably secured to the body l0 of the heater land a fuel delivery conduit 17 extends longitudinally of the heater and supplies gas to the Bunsen burner tubes l5. The rear edges of the walls of the heat defining chamber; are prelferably bentas at 18 to support the clay bac rlhe clay back consists in the present instance of three sections 19 which as hereinbefore stated, enables the size of the clay back to be varied by increasingor decreasingthe number of central sections and` furthermore oifers the advantageof enabling one section to be replaced in case of dama-ge there-to as opposed to a replacement of the whole back.
The clay back is formed with a plurality of recesses 2O which are preferably triangular in cross-section to adapt them to receive projections or lugs 21, which are formed separately and inserted within the recesses and held therein by cement 22, or the like. Extending from the bottom of each recess to the back of the clay back 19 is a restricted opening or passageway 23. Therefore, should any of the projections 21 become broken an instrument may be inserted in the restricted .opening 23 and the stub of the broken projection be ejected from the recess 20 thereby enabling a new projection to be inserted therein.
Vhile have shown the recesses 20 as triangular in cross-section and the projections 21 as of a corresponding cross-sectional shape, it is obvious that the shape of `the recesses and projections may be varied as the occasion demands and asthe style of the heater suggests. In any event, the clay back sections 19 would be cast with the recesses of the desired shape and the lugs or projections of a corresponding shape inserted therein and held in place by cement or any other Suitable means.` The restricted apertures 23 would in every instance enable the stub of a bro-ken projection to be ejected whereupon a new lug or projection could be inserted in the said recess.
It is obvious from the foregoing that I have provided a .clay back with studs or projections of such dimensions as to enable them to be thoroughly and quickly` heated so that they will become radiant and the desired optical .effect Y produced. lFuthermore, the life of a clay back is materiallyincreased inasmuch as its usefulness is not destroyed when one or mlore of the projections or studs are broken inasmuch as these may be readily replaced in the manner above referred to. It should also be noted that a clay back in accordance with my in vention may be more cheaply manufactured inasmuch as the back can be more conveniently cast with recesses therein than with projections thereon.
While I have illustrated one physical embodiment of my invention and as applied to one particular type of gas` heater it' should be understood that I do not wish to .be vunnecessarily limited by my disclosure inasmuch as my invention is capable of various modifications and equally applicable to various types of gas heaters employing clay tire backs and to this end I reserve the right to inlalre such changes in arrangement and structure as may come within theV pur view of the acccompanying claims.
Having thus described my invention, what I claim is:
1. in a fire clay back for gas heaters a sectional body formed with a plurality of staggered recesses, separate stud projections adapted to be inserted in said recesses and restricted openings in the back of said body communicating with said recesses, for the purpose described.
2. A nre back for gas heaters formed in sections, each section being provided with a plurality of recesses, separate lugs adapted te be inserted in said recesses and secured therein so as to project from one face of said lire back and restricted openings communicating with said recesses, `for the purpose set forth.
3. The combination with a gas heater of the class described of a fire back formed in sections, said back being provided with a plurality of recesses, a plurality of stud projections adapted to be inserted in said ref cesses and secured therein so as t-o project from the front of said fire back, means for securing said projections in said recesses and restricted openings in the rear of said fire back and communicating with said recessesl whereby lsaid projections may be forced out of said recesses.
