IMPROVEMENT IN SAD-IRON HEATERS.

Specification forming part of Letters Patent No. 17,56l, dated June 13, 1876; application lilcd n May 11, 1876.

heated by an admixture of air with gas or' other inliammable vapor, said improvements having' special reference to Letters Patent No. 151,160, dated May 19, 1874, granted to John Robertson ,for improvements in hand and sad irons.

My improvements relate, first, to the airforcing apparatus; second,`to means for carbureting the air priorto its entry into the body of the iron; third, to means for mingling ordinary coal or illuminating gas with the carbureted air, prior to its entry into the body of the iron 5 fourth, to the construction of the iron itself.

The nature of my improvements, andthe manner in which the same are or may be carried into effect, can bestbe explained by ref erence to the accompanying drawings, in which- Figure 1 is a perspective view of the airforeing and carbureting apparatus andthe iron. Fig. 2 is a transverse vertical section of the air-forcing apparatus.v Fig. 3 is atransverse vertical section of the iron. Fig. 4 is a perspective view ofthe movable distributingchamber, removed from the iron and turned bottom upward. l

The supply of Yair is furnished by the bellows A, upon the upper leaf of which the operator stands. The bellows is worked by the operator, who, by shiftin g his weight alternately from one foot to the other, causesthe upper leaf to rock first to one side and then to the other side Aof the central ridge or fulcrum upon which it moves. The `bellows resembles that described in Robertsons patent aforesaid, save that the leaf rocks inthe direction of its length instead of its width. In the inside of the bellows are two iiap valves for the admission of air. Bis the air reservoir and regulator, consisting of a circular bottom, a, of wood or other suitable material,

laid a sheet ofelastic and expansible rubber cloth, b, lixed round the edge, so as to be airtight, by cement, and a metal band, c,.sunk into the groove, which band is tightened by means of a screw, d. O is a pipe attached to the reservoir and fitting into ac orrespondiug aperture, e, in the bellows. When the bellows is operated, the air passes through pipe O, iniiating the regulator, as shown in Fig. 2. D is a safety-valve in bottom of the regulator, operated by a cord attached to center of the rubber cover. The tendency ofthe stretched rubber cover to contract presses the air into the naphtha-tank F, through connecting-pipe G. The air reservoir or regulator may be hinged to the bellows, as shown at f, on a horizontal axis, which will permit the regulator to be turned up and over the bellows, so as to rest dat on the top leaf of the same, as indicated in Fig. 2, in dotted lines. For this purpose the pipe G is not fixed to the bellows, but lits closely against or into a packing with whichl the aperture or socket e should be furnished. The airforcing apparatus thus organized is simple and may be conveniently packed for transportation. When not in use, the one part may be folded over on the other, and the whole moved to any convenient place without separating from it either the iron or the connecting-tubes.

The naphtha-tank or carbureting-vessel F is constructed internally in any suitable manner to effect the impregnation of the air by the hydrocarbon contained therein. For the purpose of effecting more thorough carburation, I arrange the carbureter F so that it shall be agitated by the movement ofthe bel-v lows. For this purpose the tank is hung on journals or rollers, as shown, and is connected at one side to the upper leaf of the bellows, by a crank, G, so that the vessel will oscillate or rock with the movement of the bellows. The carbureterl bellows and regulator are mounted on one platformor base,.so that lthe apparatus, as a whole, is portable and easily moved, as above stated. is conducted through the eXible tube H to the iron It. The supply can be regulated by a cock, I.

be required. For this purpose I provide for mingling ordinary coal-gas with the carbureter-air, using substantially the samearrange` ment as shown in the Robertson patent afore-A saidthat is to say, the cock I is a double cock, one branch, designed to receive the carbureted air, and the other branch y to receive, through another iexibie tube, ordinary coal-gas. The gas and curbureted air, in regulated quantity-determined by the cocks I,

any other suitable material. In this instance I have represented it made with the upper. part la, of iron and the under part i of lire-clay. The distributing-chamber I make removable,

or feet on the lower part of the chamber down against the bottom of the iron. The distributing-chamber is perforated on its under side with numerous tine holes, which, when a light' is applied, a clear blue flame radiates down on the sole of the iron.

The perforations 7c which are around the enrire bottom and top of the sides 'of the iron are for the purpose of promotinga current of air through the ir0n,'thus enabling the gas tov herein described. The inflammable material,

Having described my improvement, what I claim, and desire to secure by Letters Patent, 1s-

'1. The combination of the bellows and the air reservoir or regulator hinged and connected therewith, substantially as and for the purpose set forth.

2'. The air reservoir or regulator, consisting of the base with apertures for 'ingress and egress of air and the elastic and extensible rubber cover, combined and arranged as shown and set forth.

3. The combination of the bellows and the naphtha tank or carbureter, arranged to be agitated or rocked by the movement of the bellows, substantially as set forth.

4. The combination, substantially as shown and described, of the bellows, thefcarbureter, the air reservoir or regulator, and the iron.

5. The combination, substantially as shown Iand described, of' the body oi' the iron, the

removable distributing-chamber, and the'set or pressure' screw, which holds the chamber in place by pressing it against the bottom of the iron, as set forth.

In testimony that I claim the foregoing as my own I ax my signature in presence of two witnesses.
