SUMMER-FR ON T GAS-G RATE.

SPECIFICATION forming part of Letters Patent No. 650,137, dated May 2 2,- loco. Application filed December 12, 1898: Serial No. 699,044. (No model.)

To on whom it may concerm',

Be it known that I, GEORGE E. SHARPE, a citizen of the United States, residing at Steubenville, in the county of Jefferson and State of Ohio, have invented certain new anduseful Improvements in Summer-Front Gas- Grates, of which the following is a specification.

My present invention relates to improvements in gas grates or stoves, and has particular reference to that class which is prima" rily designed to be placed in open fireplaces.

The principal object of this invention is to provide a gas-grate in the form of a combined burner and summer-front which may be readily adapted to close any ordinary fireplace with frames having square openings or circular tops and which will safeguard against contact of dresses or other movable objects with the flame. j

A summer-front, as is well known, besides its other functions is designed to hide the coal-grate from view at certain seasons of the year. In addition to these my invention presents the advantages of a gas-grate which may be used in place of the hidden coal-grate at times when the temperature of the apartment is low enough to necessitate some heat.

With these and other objects and advantages in View the invention consists of certain novel and useful combinations and arrangements of parts,"whichare clearly described in the following specification, and particularly pointed out in the claims forming a part hereof.

In the drawings annexed hereto and forming a part of the specification, Figure 1 is a front elevation of my improved gas-grate constructed as a burner and summer-front with the front plate removed. Fig. 2 is a removable front plate used to close the front of the gas-grate. Fig. 3 is a rear elevation of Fig. 1 with parts broken away. Fig. e is a transverse sectional view on the line 4 40f Fig. 3. Fig. 5 is a vertical sectional view on the line 5 5 of Fig. 1. Fig. 6 is a perspective view of the gas-grate proper with certain parts broken away to more clearly show the construction. Fig. 7 is a transverse sectional view on the line 7 7 of Fig. 6, the perforated plate of the gas-grate being removed. Fig. 8 is a rear perspective view of the gas-grate, showing a strip or plate which may be secured to the top thereof where the combined gas-grate and summer-front are inserted in a fireplace having an upper projecting hood. Fig. 9 shows a modified form of gas-grate and summerfront designed for use in fireplaces having frames with circular tops. Fig. 10 is a detail view of the strip or plate which may be attached to the top of the gasgrate or summar-front.

Like letters of reference denote like parts throughout the several figures of the drawings.

- A'represents the frame usually surrounding the fireplaces of coal-grates, and, as shown in Figs. 1 and 9, they may be either rectangular or curvilinear. In the practice of my invention I may secure or form on these frames, integral therewith and at suitable intervals, the lugs or keepers a to retain the summer front and gas grate in position.

These lugs occur on the rear edges of the frame-opening. 13 represents a plate or casting having the functions of a summer-front, and formed therein is an opening I), which may be of any preferred shape, but which is here shown as rectangular. At the top and overhanging this opening is a hood I), which extends across from side to side. At the foot of this summer-front plate is a removable door N, which permits access 'to'the valve E and certain other parts of the gas grate or stove, to be described farther on. As is obvious, this summer-front plate B maybe ornamental or plain. At each lower corner of the rectangular opening b is formed a keeper b These keepers are designed to retain in place a removable front plate W. This plate closes the front of the summer-front plate and may be plain or of open-work and maybe 0rnamented in any style to enhance the beauty of the summer-front. c

As the openings of all fireplaces are not of equal size,but may Vary several inches, I have provided means for adapting my summerfront gas-grate to any size or shape offopening. casting'B and on the front face thereof the adjustable wings B B. These wings are slotted at suitable distances from the top and bottom, as at b b, and through these slots extend the pins or studs 11 which are secured Isecure on each side of the plate or 5 justment of the wings B to close the-open ings at either side of-the summer-front plate B, where it is notas wide as that of the tire; place-opening. To close any opening at the top, I provide a plate B secured to the top of the summenfront plate by bolt and nut passing through a vertical slot b to permit vertical adjustment, and secured to this plate by bolts andnuts passing through horiZontaF slots 11 are extension-plates B These extem 15 tension-plates, where they meet centrally, are a a sort of slot conformingto cut away to form slott'fin the plateB A 'Ifotherearffacejof the summer-front plate B. may be secured yb or conn c ed in any eenvenient manner the gas grate or stove proper. Thisigas grate or stove. maybe of any suitable construction, or it may be as .sho in thefdrawings. As, there illustrated it consists of a pan-shaped plate 0, formed,

preferably, of one piece of seamless sheet,

metal, the top and sides of which areproded with. flanges. by Which'the pan maybe.

40 tom thereof and in a central position, and

over'this; opening is secured a hood-shaped plate 1),,wh'1ch forms an air and gas mixer, leading to the reservoir 0?. Secured to the panQ in any suitable manner is a gas-valve 5 E,w hose n pplee projects a certain distance into the ho odof the air and gas mixer, the

lower part o'fwhich is flared somewhat to admitjairi with the gas. I The two commingle be e entering e eservoir.

B 1'3,' '1' S98 Toprevent deterioration of the platep, I cover the same with a sheet of as.- bestos paper 0. This prevents rusting and increases durability. of the fire-surface. Be-

tweenthe perforations in the plate 0 which 6o areleft exposed and are here shown in par-. 1

allel, lines, I coat the surface with asbestos.

C in the fibrous state. This asbestos may alsbjcoat the entire visible front of the, gas

grate or stove, and the object. is too well n known to require explanation.

'Tofinish theappearance of the, gas-stove,

I finay insertastrip between the asbestos? These slots, being V The lower part 50 ofthjsvalve has a tube or pipe connection.

(Not shown); This valve or serve as a kind of false bottom and hide the mixer from View.

Inter-posed between the gas-grate and the summer-front plate B and covering the opening in the latter is a sheet or web of foraminous rnaterial G, preferably woven wire of fine mesh. This foraminous web serves to prevent the escape into the room of gas or noxious odors arising from the burning gas, and aside from this its principal object it serves as a guard to prevent dresses or other moving objects from coming into contact with the flame. B'yconstruct ingthebody of the gas-grate as shown with the reservoir pressed therefrom no gas can possibly escape fromthebaek of the same. web between the gas-grate. andthe opening of the summer-front plate. none canle'scape through that source into, the. room. Oon'se-.

quently a chief objection to gas-stofvesis removed; 7

In Fig. 9 I have shown a modified fo rin of construction whereby a summer-front g asgrate is adaptable to..fireplace s Qhavingfa.

scribed for the. preferred form," so that the wings may be. adj listed laterally to close'eny iopenin g which may occuratthetop andsides *of the summer-front gas-grate.

In-Figs. Sand 10 I have shown apla'te H, which may be used where the fireplace=firanje is formed with an overhanginghood, such as shown. at H, dotted lines, in Fig. 5.; This iplateiscut with a curved edge, as shown,

and has the downturned flange, h, by. which it is secured upon the top of the gas-grate. The vertical. slot h. is formed therein. centrally to fit. over the. bolt, which. secures-the upper adjustable plateonwing Bi, The fiange of this plate H may be. inserted between the plate and the. washer on the. boltandthereliy clamped in place.

L This completes the construction of my invention, and its operation will be readily .understood from the foregoing description without. further explanation.

I do. not desire to limit myself to the pre' cise details of construction herein. shown and described nor to the exact arrangement. or location of parts, but reserve. to myselffthe right'and privilege to alter the. samewithin the. .boundsof mechanical skill without departing from the spirit. of my invention.

( Havingthus fully described .inyrinvention, what I claim as new, and desire to secure. by Letters Patentof the United States, is}

p 1. The. combination with a fireplace-frame havingon its rear face upper and lower opposing lugs or keepers, of a burner and summer-front provided with laterally-adj ustable side extensions or wings which; rest orabut against said lugs or keepers, and a top extension for said burner and summer-front which is both laterally and vertically adjustable and projects upwardly behind the fireplace-frame, substantially as described and set forth.
