RIGHT TO VILLIAM KAP- S A D I R O N SPECIFICATION forming part of Letters Patent No. 406,943, dated July 16, 1889.

Application tiled April 20, 1888. Serial No. 271,299. (No model.)

To all whom it may concern:

2e it known that we, SPARRow M. NIC/K- ERsoN and (f -xLvIN J. HOLMAN, citizens of the United States, and residents of Chicago, in the conntyof Cook and State of Illinois, have invented certain new and useful Improvements in Sad-Irons, of which the following' is a specification.

'lhis invention relates to improvements in sad-irons hea-ted internally by means of Hainejets, and has for its objects an iron so constructed as to prevent the escape of the flame from the iron during the use thereof, and also the breaking up and distribution of the anie, so as to promote its heating effect upon the iron, and a more perfect combustion of the gases employed for heating the iron from its interior, and finally to mix the supply of gas to an iron previous to its discharge into the burner of said iron, whereby perfect combustion by the burner is correspondingly promoted. \Ve attain these objects by the devices illustrated in the accompanying drawings, in which-A Figure l represents a central vertical seetion of a sad-iron embodying our invention, Fig. 2,a horizontal section of the iron on line 2 2 of Fig. 3, and Fig. S a central vertical se?.- tion of the iron.

Similar letters of reference indicate the saine parts in the several figures of the drawings.

Referring by letter to the accompanying drawings, A indicates the usual wooden handle, and I5 B the bail or supports thereof, the support 'l extending` downwardly a suitable distance to form a pivotal bearing for the iron body, while the support B is shorter and extends at an oblique angle from the handle, the outer end of which is formed into au eye C, in which is rigidly secured, by screwing or otherwise, one end of a vertical pipe I),to the lower end of which and extending at rightangles thereto is secured another pipe E, proj ecting toward the support l, and perforated, as shown, preferably on the under side there- This perforated pipe is closed at the end thereof and constitutes one bearing of the iron body F, one end of which bears thereon near the vertical pipe D, while the opposite end of said iron has cast thereon or otherwise rigidly secured thereto a trunnion G, which works through an eye in the lower end of the support B and constitutes the other bearing of the body, which is thus loosely journaled within the handle and free to revolve on its bearings.

To the end of the trunnion G, projecting beyond the supports B, is pivotally secured a rod H, provided with a knob I on the end th ereof, an d constitu tin g the handle, by means of which the iron may be revolved upon its pivot, the said rod being adapted and arranged to be forced between opposing spring jaws or catches J, attached to the handle-support B, so as to lock the iron in either of its adjusted positions.

To the upper end of the pipe l), projecting beyond the eye C., is secured a nozzle constitilting an air-chamber K, perforated at L for the admission of air, and with the nozzle is connected, byineans of a swi\'feljoint, a metal lic pipe M ,either straight or curved, as shown, to the opposite end of which is secured a rubber or other flexible supply-pipe N, through which gas is conducted to the iron, the perforations in the nozzle admitting sufficient atmospheric air for the purposes of combustion, which mixes with the gas before its discharge into and ignition in the iron.

The swivel-connection between the supplypipe N and the iron enables a free movement of the iron in any direction without danger of twisting or bending the pipe and thereby cutting off the gas-supply, and the iron may be used equally well at any point within the radiusof thesupply-pipe. ]esides,theconnection between the vfiexible supply-pipe and the iron is thereby effected at such a height above the articles being ironed to greatly facilitate the work of the operator by holding the pipe always out of the way.

The principal feature of our invention, however, is the coi'istruction of the interior of the body of the iron, which walls have heretofore been made plain in hollowing out the interior thereof, so as to provide a heatingspace for the burner; but practice has ,deinem strated that with an iron so constructed the heated air and products of combustion not only pass quickly and directly out of the perforations a, formed in the side Walls thereof, first toward one end and then toward the other as the iron is moved back and forth, but frequently the jetllames Will issue through said perforations and burn both the hand of the operator and the garment being ironed. In order to avoid this objection and at the same time economize the heat, We have provided the body of the iron between each pair of perforations with vertical ribs b and horizontal ribs c, projecting inwardly from the side Walls of the iron toward the center, leaving only sufficient roomV for the insertion of the burner and the passage around it of the heated air and products of combustion. These ribs all tend to deiiect the flame-jets and obstruct the exit of the heated air and products of combustion, thehorizontal ribs eifectually preventing the direct rising of the llames through and out of the upper sets of perforations, While the vertical ribs not only materially aid the horizontal ribs in their function by making tortuous passages for the exit of the products of combustion, but prevent direct and insetting drafts from either side, occasioned by the rapid movements of the iron, from acting on the `flame-jets and forcing them through the perforations in the iron.

Another important result is the saving of fuel effected by this construction, due to the increased heating` capacity of the fuel, owing partly to the detention of the products of combustion within the iron and partly to the increased radiating-surface furnished by the dei-lecting-ribs, and this saving is important foratwofold reason, iirst, because of the saving in fuel, and, second, the saving of the time of the operator, because the iron will not have t0 be so often reversed.

Having described our invention, what We desire to secure by Let-ters Patent is l. A hollow internally-heated sad-iron having vertical ribs b projecting from the side Walls and formed integral with the face of the iron, and perforations between said ribs, substantially as described.

2. A hollow internally-heated sad-iron provided With Vertical ribs Zi and horizontal ribs c, projecting from the side Walls of the iron, the Vertical ribs being integral with the face of the iron, substantially as described.
