GAS-HEATER.

Application led May 3,

To all whom t may concern.'

Be it known that I, BERNHARD COLUMBUS, a citizen of the United' States, residing in New York, county of Bronx, and State of New York, have invented certain new and useful Improvements in Gras-Heaters, of which the following is a specification.

My invention relates to an improved heater; particularly a gas heater designed for attachment to an ordinary gas lighting fixture.

The primary object of my invention is to provide a gas heater of simple construction and made up of parts that can very easily be assembled; the said parts being relatively in xpensive to produce, whereby the heater can be made in large quantities at relatively low cost.

The above and other objects and advantages of my invention will be clearly lset forth in the following description, taken yin connection with the accompanying drawings, and the novel features of my improved heater will be precisely defined in the appended claims, This description, however, is'explanatory only and I may of course make alterations in what is actually shown herein, especially as regards matters relating to the size, shape and arrangement of parts; to the full extent indicated by the general meanings of the terms in which the claims are expressed and by variations in the wording of the same.

On the drawings- Figure 1 is a side view partly in section showing my improved heater mounted upon a gas fixture, and

Fig. 2 is a similar form of heater.

The same numerals identify the same parts throughout.

In the particular description of the drawings I use the numeral 1 in Fig. 1 to indicate a burner, which carries a diffusion member comprising a top 2 and a support 3, and adapted to be attached to the burner when the parts of the heater are assembled. The diffusion member is aiiixed tc one end of the burner 1 and the other end of this burner can be attached to a gas lighting fixture 4; having a threaded nipple 5. The burner 1 includes a stem 6 having inside threads to enable it to be quickly screwed upon the fixture 4 when it is desired to put the heater in position for use, When so mounted the heater will extend from the view showing another Specification of Letters Patent.

fixture +L upward and the top 2, which will be of large diameter relative to the burner, will serve with the support 3 to diffuse the heat iny the usual manner.

The burner 1 is made 'up of a flaring section 7 c attached to a hemispherical or domeshaped section 8. Preferably the section 7 is integral with the stem 6, and it is located at the end of the stem opposite the threaded end for engaging the nipple 5. rlhe section 7 has a bead 9 extending around the rim of same and fitting into the adjacent end of the section 8 and sections 7 and 8 are united preferably by spinning or otherwise working the edge or rim l() of the section 8 over upon the bead 9; thereby making a beaded joint between the sections. In the section 8, just above this beaded joint, I provide plurality of jet openings 11 which extend all `around the burner; and from the top of this section 8, which forms the upper portion of the burner, extends a cylindrical projection, such as a boss 12. This cylindrical boss 12 is received in an opening at the center of the support 3, which thus engages it, and this boss is preferably made to lit the support tightly.

The edge ofthe top or deflector 2 is turned down as indicated at 13, giving this top the form of a dish shaped plate; and when the top 2 and burner 1 are united the down turned edge of the top 2 will be considerably higher than the jet openings 11. The utility of this construction is due to the fact that the jets of burning gas issuing from the openings 11 and extending directly away from the burner naturally tend to curl upward at'their outer ends, and' the currents of heated air created by them flowing outward toward the rim of the imperforate top 2 are turned downward by the rim 13; and thus the heat of the burner is diffused evenly through the apartment.

The nipple 5 normally carries la short piece of tubing which has the gas lightingy tip on its outer end. In order to apply my heater it is only necessary to unscrew this section carrying the burner tip, remove it and apply the heater by screwing the stem 6 upon the nipple 5 as far as it will go. rlhe usual ornamental collar 14 surrounding this nipple need not be removed.

I prefer to give the support 3 the shape 'I of an inverted cone having an opening at its apex to engage the boss 12. This cone may be made of a sheet of metal, perfoy cia outward and upward.

rated or not, as desired, and it has projections 15 passing through openings 16 in the top 2, and then bent over, to lsecure it to the top.

I may also make the section 8 wit-h an outer circumferential shoulder 17, serving as a seat for a coil of `wire 18, extending from the shoulder 17 up to the support 3.

This Wire assists in diffusing the heat fromv `portion 19, with jet openings 11, and on accountof the sloping surface vof .the .portion 19, the Vjets at these openings will be .directed diagonally away from the burner, vor Above the `portion 19 the section 8 has inade fast thereto a kcylindrical projection in the form .of a collar 20. Around `this collar `is placed the lower end of a cylindrical support 21, the support engaging the collar and resting upon .the burner;`r and the support has a cap 22 at its .upper end fastened by rivet 23 to the top This support 2l may be perforated .or not, like the support 3.

It will be seen .that vthe construction of my improved heater is very simple as allrof the parts can be stamped .out and made in one piece. To unite the sections 7 and 8 only -a single operation is required and the burner andthe diffusion member can be secured to each other simply by fitting the support over the boss 12, or the collar 20, as the case may be. This inode of assembling will hold` the burner and the diffusion member to each other and if they come apart anyone can at once reunite them. Of course if desired the support 3 may be soldered to the burner or positively secured thereto in any other convenient manner.

Though shown in vertical position as the The supports 3 and 21 are preferably perforated to let air circulate therethrough and facilitate combustion of the gas at the jet openings 11.

Having described my invention what I believe to be new and desire to secure and protect by Letters Patent of the United States is:

1. In a gas heater, a Haring section having a stem and a hemispheric-al section united .to the iaring section by a beaded joint, the hemispherical section having openings adjacent said joint .to provide jets eX- tending directly away from said sections, a boss on the hemispherical section, a support having the shape of an inverted cone engaging said boss, a deiiector afliXed to the support, and .a wire ,encircling the hemispherical section. Y

2. In a gas heater, aflaring section having a stem, and a hemispherical section united `to the flaring ysection by a beaded joint, the hemispher-ical section' having openings adj acent said joint to provide jets extending directly away from said sections, a boss on the hemispherical section, a support having .the shape of an inverted cone engaging the boss, and an imperforate top having downturned edges, said support having projections to yengage the top, and secure thesupport and the top together. v

3. In a gas heater, a burner including a pair of sections united by a beaded joint, said sections each contracting away from said joint, one of said sections having open-V ings therethrough to provide a plurality of jets, a cylindrical projection .carried by said section, a perforated support receiving said projection, and an imperforate .top having downturned edges afIiXed to said support.

In testimony whereof, I have signed my name to this specification this V30th vday of April, 1918.

BERNHARD COLUMBUS.
