Specification of Lettersl'atent.

Application filed September 1, 1915; Serial No. 48,442.

To all whom it may concern:

Be it known that I, J OHN'S. PANAsnvrroH, a citizen of the United States, and resident of Northampton, in the county of Hampshire and State of Massachusetts, have invented certain new and useful Improvements in Gas Heaters and Cookers, of which the following is a specification.

My invention relates to new and useful improvements in gas heaters and cookers and particularly to that class of stoves shown and described in my'Patent #900,303 dated October 6, 1908.

The object of the invention is to provide a compact, simple and inexpensive form of portable gas heater which can be made and sold at a reasonable figure, to generally improve upon the construction of the heater shown in the patent before mentioned in a way to produce improved results in the matter of combustion and radiation, further to provide a heater which can be readily moved from room to room and connected to the usual gas outlets by means of a flexible pipe connection and further to provide means for tying the series of lining bricks together so as to form an assemblage that can be handled as a unit, as will be later more fully explained.

Upon the accompanying drawings forming a part of this specification similar characters of reference will be found to designate like or corresponding parts throughout the several figuresand of which Figure 1 shows a side elevation of my improved form of gas heater complete.

Fig. 2 shows a detached side view of the assembled series of lining bricks employed within the heater casing.

Fig. 3 is a central vertical longitudinal section taken through the complete appara tus shown in Fig. 1 with the Wiring omitted.

Fig. 4 is a plan or top end view of the top brick shown in Figs. 2 and 3.

Fig. 5 is an inverted plan view Qf'fOIlG of the intermediate bricks shown in both Figs. 2 and 3. r

Fig. 6 is a plan view of a perforated plate employed between the bricks as shown in Figs. 2 and 3 and Fig. 7 is an inverted plan view of another of the intermediate bricks. I

Referring in detailto the characters of reference marked upon the drawings, 10 represents the casing of the heater, WhlCh wall of the casing also includes a series of perforations 13 around its lower end portion and a like series 14 around its upper edge portion.

A cover 15 is adapted to set on the top end of the cylindrical casing and is preferably perforated as shown. A supporting plate 16 is mounted upon this top through the me"- dium of posts 17 that rest upon the top ano are secured thereto by means of screws 18 as shown. This supporting plate is obviously to serve to receive a vessel or cooking utensil that is to be heated vby the stove when used for cooking purposes. A suitable gas burner 19 is supported within the lower end of the casing and is provided with an elbow and pipe extension 20 through which the supply of gas is fed to the burner. A cook 21 is connected to this pipe for the purpose of regulating the supply of gas to the stove.

The fire bricks of which there may be any desired number are for the most part alike in construction and are duplicates of each other with the exception of the top and bottom bricks. When assembled and wired together they form a cylindrical stack which may be readily slipped into and removed from the stove casing from the top end and bythe removal of the cover. The lower brick 22 is longer than the other bricks and is cylindrical in form and has both ends open. It is provided with side openings 23 through which air is admitted to the combustion chamber 241 within the cylinder. Thischamber is sufiiciently'large to accommodate the burner and flame from the same.

This brick thus serves as one of the membars which surround the flame and is brought more or less incontact therewith. Upon this bottom brick member is piled and arranged a series of intermediate bricks 25 and 26. The bricks 26 are alike in construction and are arranged one upon the other. The

brick 26 is shown in detail in Fig. 5 and as will be .noted is of a general annular formation including a cylindrical side wall Patented Mar. 6, 1917.

. relatively lower angular shaped openings 30 which form bridge portions 31 that extend across the center of the top of the brick and serve to retard and distribute the heat that rises from the burner. Openings are thus formed inside and up through the brick and serve as a passageway for the heat to go up through the stove.

- The perforated sheet metal member 29, as shown in Fig. 6, is laid between the two lower bricks 25 and 26 in the manner indi? cated in Fig. 3 and thus not only serves to stiffen the construction, but also to better deflect the rays of heat outward as they rise from the burner. The shape of this plate 25) is somewhat like the top face of the bricks and thus includes openings and bridge portions. The top brick which is designated as 32 differs from the intermediate series of bricks in that instead of having the openings and bridges, so called, it is provided with a series of small holes 33 which are formed therethrough. When the series of bricks are assembled as shown in the drawings the heat from the burner rises and spreads more or less in a way to thoroughly heat the bricks thus insuring perfect combustion of the gas and besides produces a uniform and prolonged form of radiation which is not possible with a plain form of burner.

In addition to the said formation and arrangement of the bricks. as above described I employ means for holding the bricks together so as to enable one to readily place the same in position in the heater and to remove them as occasion requires. This I accomplish by providing a wire 34 around the top brick 32 and a somewhat similar band 35 around the bottom brick 22. Each of these two Wire metal bands is provided with a series of inturned hook extensions 36 that overlap the edge portion of the brick and also outwardly disposed extensions 37, that'serve to centrally space the assembled bricks within the casing. extended loops 39 to which longitudinal intermediate wires 40 are attached. These wires extend from the loopsof one band to those of the others to bind the series together and retain them in alinement. These I further provide amazes intermediate wires are tied together by girdl ing .wires 41 that are secured to the longltu- (linal wires and extend around the bricks to hold them in position. These Wires are so arranged as not to cross any of the holes in the sides of the bricks.

Havingthus described my invention what I claim and desire to secure by Letters Patent is V 1. A gas heater comprising a casing, a burner mounted therein, a series of annular fire bricks mounted therein one upon the other, the top brick being wholly and the remaining bricks being partially covered, a wire encircling each brick, the wire of the top brickehgaging the upper edge thereof and the wire of the bottom brick engaging the same, and longitudinal wires connecting the aforesaid encircling wires.

' 2. A gas heater comprising a casing, a

burner mounted therein, a series of annular fire bricks mounted therein one above the other, the top brick being Wholly covered and the remaining bricks being partially covered, a wire encircling each of said bricks, longitudinal wires connecting said encircling wires and connections on said longitudinal wires and on the encircling wires of the top and bottom bricks engaged with portions of said latter bricks for holding the series together.

3. A gas heater comprising a casing having perforated sides, top and bottom, a

burner mounted therein, a series of annular fire bricks arranged one above the other within the casing, and having openings in their sides, a band encircling each of said bricks, the bands encircling the top and bottom bricks also securely engaged with the same respectively, and longitudinal bands connecting each of the aforesaid encircling bands to hold the same in place and to retain the series of bricks together.

Signed at Bridgeport in the county of Fairfield and State of Connecticut this 22nd day of AprilA. D., 1915.
