4GAS-HEATED IRON.

SPECIFICATION forlrling` part of Letters Patent N 0. 699,683, dated May 13, 1902. Application filed December 18, 1901. Serial No. 86,344. (No model.)

To all whom t may concern.-

Be it known that I, BENJAMIN N. I-IAwns, a citizen of the United States, residing in the city of Washington, District of Columbia, have invented certain new and useful Improvements in Gas-Heated Irons; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful4 improvements in gas-heated flat-irons.

The primary object of the invention is to provide an iron of simple construction in which the gas will be ymixed with the air in such a way that perfect combustion will be effected and the maximum amount of heat obtained with economical use of gas.

A further object of the invention is to provide an iron in which the burner canbe readily adjusted vertically within the body of the iron to adapt said iron to the different gaspressures and in which the necessary heating capacity under all conditions likely to oceur will be provided for..

Other objects and advantages looking to the general improvement of irons of this character will become apparent in the course of the following description, and the points of novelty will be set forth in the claims.

In the drawings illustrating my invention, Figure 1 is a perspective view of the iron complete. Fig. 2 is a central longitudinal section thereof. Fig. 3 is a transverse section taken about on the line :c of Fig. 2. Fig. 4 is a detail perspective View of the burner detached. Fig. 5 is a perspective view showing a slightly-modied form of burner. Fig. 6 is a perspective View of the burner adapted for use with the iron illustrated in Fig.

Referring to the drawings, the numeral 1 indicates the body of the iron, which is hollow and preferably formed in the usual and well-known shape and is provided at or near its bottom with a series of air-inlet openings 2.

In carrying out my invention I provide the iron with an opening 3 in its rear wall 4, in which is inserted a burner 5, which I preferably construct in a single piece, approximately rectangular in form, but provided with inclined lower edges 5, having therein gasopenings 6, so arranged with relation to the bottom of the iron and inlet-openings 2 that a complete admixture of the air and gas will be effected as the air is drawn in through said openings 2, and thus a more regular and uniform heating of the pressing-surface of the iron will be obtained.

Preferably integral with the burner is provided an upwardly-extending ear 7, having therein a vertical slot 8, adapted to register with a similar slot 9 in a downwardly-extending ear 10, preferably integral with 'the top plate 11 of the iron.

The numeral l2 indicates a bolt which I prefer to employ and adapted to pass through the ears 7 and 10 and a narrow slot lOin the rear wall of the iron-and is adapted to hold said burner to the body of the iron and to permit a vertical adjustment of said burner when desired and also to hold the rear end of the top plate in place upon the body of the iron, the front end of said plate being held in position by a set-screw. In the forward end of the burner, to the under side thereof, is an adjusting-screw 13, which has its lower end resting, preferably, on the floor 0f the iron, a1- though, if found desirable, it may be made to rest on a lug or other suitable means secured within said iron-body, as is evident.

The numeral 14 indicates an ordinary joint or connection, preferably screwed into the rear end of the burner 5, as shown, and adapted to receive a short vertical pipe 15, provided with perforations 1G for admission of air to mix with the gas as it passes to the burner in the iron, and a stop-cock 17, adapted to receive on one end thereof the usual iiexible tubing, (not shown,) asis common in this class of gas-fittings.

Interposed between the iron-bod y l and the top plate 11 is a plate of asbestos or` other heatnon-conducting material 1S to prevent the heat from the iron reaching the handle. I preferably provide the `top plate 11` with standards 19, provided near their upper ends with open slots 2O to receive the rod 21 of the handle and permit a vertical adjustment of the same. In order that the heat from the iron be prevented reaching the handle 22, I

preferably provide'asbcstos washers 23, in-

terposed between the wooden portion of the handle and the metallic standards 19.

Referring particularly to Fig. 5 and Fig. 6, the numeral 24 indicates a burner formed with a mixing-chamber 25, provided with an internally-screw-threaded aperture 26 for the reception of a pipe 27, similar to the pipe 15 just described. In order that this burner may be vertically adjustable I provide an ear 28, preferably cast integral with the mixing-chamber 25 and adapted to be heldin contact with a depending ear 10 on the top plate of the irony by the bolt 12. As a further means for securing this form of burner rigidly in the body of the iron I preferably provide a short lateral extension 29, having therein an open slot 30 to receive a screw 31, which, in conjunction with the bolt 12, serves tohold the burner in desired adj usted position. It will be observed that the body and top plate of the iron shown in Fig. 5 are'the same as those shown in Fig. 1.

I preferably extend the plate 11 of the iron considerably beyond one side wall of the chamber, and the said wall of said chamber is preferably cut away, as indicated by the numeral 32, to permit the escape ofv heat, which will be deflected by lthis lateral eXtension of the plate 11 for the obvious purpose of preventing the heat from reaching the hand of the user. In order to increase the heatingsurface of the iron, I preferably, though not necessarily, corrugate the iloor of the iron, as shown by the numeral 33.

In irons of this general character it is highly important that a perfect admixture of the air and gas be effected, and with this object in view I preferably provide the burner 5 with the openings 6 opposite the perforations 2, so that the air in coming through said perforations will be brought in contact with the obliquely-projected flame from the burner, thus producing perfect combustion and preventing the smutting of the bottom of the iron adjacent to the burner.

Minor modifications involving mechanical skill may be made Without departing from the spirit of the invention.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. In a gas-heated iiat-iron, the combination with a hollow body provided with airinlet openings near the bottom thereof, and a rectangular opening in its rear wall, of a burner in said body of less size than the opening in the rear wall and provided with a slotted ear, a top plate provided with a slotted ear adapted to register with the ear on the burner, and means for locking the two ears and body together, whereby the top plate is held to the body and the burner locked in any adjusted position with relation to the bottom of the body, substantially as described.

2. In a gas-heated fiat-iron, the combination with a hollow body provided with airinlet openings near the bottom thereof, and a rectangular opening lin its rear wall, of a burner in said body of less size than the opening in the rear walland provided with an ear, a top plate provided with an ear adapted to register with the ear on the burner, and means for locking the two ears and bod.)7 together, whereby the top plate is held to the body and the burner locked in any adjusted position with relation to the bottom of the body, substantially as described.

3. In a gas-heated fiat-iron, the combination with a hollow body provided with airinlet openings near the bottom thereof, and a rectangular opening in its rear wall and a narrow slot also in said wall, a burner in said body of less size than the rectangular opening and provided with a slotted ear, a top plate provided with a slotted ear adapted to register with the ear on the burner and with the slot in the rear wall of the body, a bolt passing through the slots in the ears and the slot in the body, whereby the top plate is held to the body and the burner locked in any adjusted position with relation to the bottom of the body, substantially as described.

4. In a gas-heated flat-iron, the combination with a hollow body provided with airinlet openings near the bottom thereof, and a rectangular opening in its rear wall, of a burner in said body of less size than said opening and provided with a slotted ear 28, and also with a slotted ear or lateral extension 29, a top plate provided with a slotted ear adapted to register with the ear 28 on the burner, means for locking the ears 10 and 2S'I to the body, and means for locking the ear or lateral extension to the body, whereby the top plate is held to the body and the burnerlocked in any adjusted position with relation to the bottom of the iron, substantially as described.

In testimony whereof I affix my signaturex in presence of two witnesses. y
