HEAT-BARRIER PLATE FOR STOVE OR RANGE FIREBACKS.
SPECIFICATION forming part of Letters Patent No. 541,404, dated June 18, 1895.
Application filed March 14, 1895' Serial No. 541,737. (No model.)
To all whom it may concern:
Be it known that 1, WILLIAM WEwERs, a citizen of the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented new and useful Improvements in Heat-Barrier Plates for Stove or Range Firebacks, of which the following is a specification.
This invention relates to that class of cook stoves or ranges wherein a front fire-box is separated from the oven-chamber by asingle metallic plate which constitutes a fire-back.-
In stoves or ranges of this character the intense heat radiated from the fire-back burns or overheats the surface of the bread, or other article in the oven, and obviously this is a serious objection.
The chief object of my present invention is to provide new and improved means for impeding or obstructing the direct radiation of the intense heat from the single plate, metal fire-back upon the bread, or other article being baked or cooked in the oven.
The invention also has for its object to provide a new and improved barrier which will impede or obstruct the direct radiation of the intense heat of the fire-back upon the article in the oven-chamber, but will not unduly confine the heat in close proximity to and thus eventually destroy the fire-back, as is the case with those stoves or ranges having an extended, imperforate, metallic surface located near the fire-back and perforated only at its upper and lower edges to secure a circulation of air against the hot fire-back and through the oven-chamber.
The invention also has for its object to impede or obstruct the direct radiation of the intense heat from the fire-back upon the article in the oven by a metallic barrier-plate possessing such characteristics that it can be conveniently and rapidly removed for repairs, or whenever circumstances render it desirable or necessary to detach the plate, or for the substitution therefor of a new barrierplate whenever occasion demands.
The invention also'has for its object to provide a barrier which will impede or obstruct the direct radiation of the heat of the fireback upon the article in the oven, but will occupy very little space, and thus render it possible to utilize all available oven space while the plate can be entirely removed without in any manner leaving the oven incomplete.
To accomplish all these objects my invention involves the features of construction and the combination or arrangement of parts hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure 1 is a vertical central sectional view through the fire-box of a cook stove or range, showing a portion of the oven-chamber. Fig. 2 is a horizontal sectional view taken on the line 2 2, Fig. 1; and Fig. 3 is a detail front elevation of the improved barrier-plate.
In order to enable those skilled in the art to make and use my invention, Iwill now describe the same in detail, referring to the drawings, wherein- The numerall indicates the single, metallic plate constituting the fire-back of the firebox 2.
The oven, of which a portion only is shown in Fig. 1, is composed partly of a topplate 3, and short, front plate 6. The single, metallic plate 1, constituting the fire-back, is secured. to the edges of the top plate 3 and short, front plate 6 of the oven-chamber through the medium of bolts '7 and 8, located about centrally between the vertical edges or ends of the fireback. The bolts 7 and 8 serve also to detach ably secure in position the improved barrierplate 9, which, as clearly shown in Fig. 3, is composed of a rectangular piece of metal, curved longitudinally, and formed with numerous perforations 10 throughout its entire body portion, which perforations constitute heat passages for the passage of heat transversely through the plate.
The barrier-plate is preferably composed of a single casting, and the numerous perforations are formed during the casting operation. The plate is provided about centrally between its ends with upwardly and downwardly projecting ears or lugs 12 and 13 having boltholes 14 and 15, through which the bolts 7 and 8 are adapted to extend, for the purpose of securing the barrier-plate in position in rear of the fire-back. The lower ear or lug 13 lies nearly in the plane of the body of the plate,
so that its bolt-hole. 15 can. properly. receive the plate 8, but theupper lug 12, is extended at an obtuse angle to the body of the barrierplate, in order to place it in such position that its bolt-hole can properly receive the bolt 7. The longitudinal curvature of the perforated barrier-plate places the end portions 16 there of against, or near to, the. fire-back, while the main body portion of the' plate swells rearwardly, or in a direction away from the fll'B'. back, and thus provides a chamber 17 which diminishes in dimensions from the center of the barrier-plate toward the extremities 16 thereof.
The perforations in the barrier-plate are very numerous, and are disposed throughout the body of the plate. from the upper to, the lower edge portions, and. from one endtothe opposite en ti. Thenumerous perforations are.
very important, in that while the barrier-plate. impedes or obstructs the direct radiation of the intense heat of the fire-back, it does not unduly confine the. heat in proximity to. the fire-back.
It has been heretofore proposed t0- place, a plate in rear of a fire-back, but the main body of the plate in the prior construction. was, imperforate, and consequently an extended im-. perforate surface in rear of the fire-back was.
alluded; to, was designed to securea circulation of air against the hot fire-back and through the oven-chamber. In a largemeastheheat in close proximity to. the, fire-back and eventually destroys the latte y or damages it seriously. Further, in the priorconstruction, the plate is a permanent fixture ofthe stove, and in fact an integral portion either of the fire-back or of the oven wall, andiconsequently the plate could not be removed and replaced, or detached for. the substitution therefor of a new plate if occasion shoulddemand.
In my invention the longitudinal, curved barrier-plate, with its numerous perforations and projecting ears or lugs, is susceptible of being conveniently and rapidly. removed for repairs, or whenever circumstances require the detachment thereof for any purposewhatever, orfor the substitution therefor of a new barrier-plate if occasion should demand.
The improved barrier-plate invented by me occupies very little space, and consequently all available oven-space is utilized. If the improved barrier-plate is detached,it in no way leaves the oven incomplete. It is an independent fixture, and not apermanent part of either the fire-back or the oven wall. It can be cast as a, separate article. and applied to a stove already in existence.
I have illustrated the improved barrierplate as. formed with projecting ears or lugs at its upper and lower edges about midway between its length, for the purpose of receiving. bolts 7 and 8, w,hich aid in securing the fire-back in position. I do not, however,
confine. myself to this particular means of detachably securing: the barrier-plate in position, as many simple ways of supporting the barrier-plate, so that it can be attached and detached, will suggest themselves without further explanation. tratedin the drawings, however, is much preferable to any other which occurs to me, in
that the ears or lugs, constructed and arranged in themauner described and shown, render it possible to detachably secure the barrier-plate in position through the medium of the bolts which serve to secure the detachable fire-back in place.
As thebarrier-plate is composed of a single casting it can be very economically manufactured, and the numerous perforations can i be made during theoasting operation, sot-hat 51,10 expense follows theprovisionof themany perforatiens necessary to secure the desired {result.

The perforations in thev barrier-plate are A serious objection to a single plate fireiback which; constitutes a partofthe front wall of theoven-chamber, residesin the fact f that intense heatis radiated, from the fireback directly upon the. top. surface, or the sides or end-oft-he' article nearestthe fire-back, and therefore the article is burned or overheated at suchpoints. I have discovered that my, improved. barrier-plate, possessing. the
characteristicssetforth, etfectually avoids the objections stated. I also find that unless the barrier-plate is provided with numerous. perforations. throughout its body portion it will not accomplish the desired result, in that it confines the intense heat tooconstantly near the fire-back and eventually destroys,orseriously damages. the. latter.
Having thus described my iuventiomwhat I claim is- 1:. The combination with the single-plate fire-back, and the oven-chamber of a stovelor range, of a removable and. replaceable. cast metal barrier-plate, constructed entirely separate from the wallsof the oven-chamber, ar-

3. The combination with the fire-back of a cook stove or range, of a longitudinally curved 1 cast metal barrier-plate constructed entirely separate from the walls of the stove and ovenchamber, detachably supported in rear of the fire-back and formed with numerous perforations throughout its body portion for impeding or obstructing theradiation of intense heat from the fire-back without unduly confining the heat in proximity thereto, substantially as described.
4. The combination with the fire-back of a cook stove or range, of a longitudinallycurved, profusely-perforated barrier-plate arranged in rear of the fire-back, and formed integral at its upper and lower portions with ears or lugs having bolt-holes to engage bolts which detachably secure the plate in position, substantially as described. a

The combination with a fire-back, oven walls, and bolts securing the fire-back in position, of a longitudinally-curved, profuselyperforated barrier-plate arranged in rear of the fire-back, and having projecting ears or lugs containing bolt-holes to receive the bolts which secure the fire-back in place, substantially as described.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
