SAD-IRON HEATER.

SPECIFICATION forming' part of Letters Patent No. 235,092, dated December 7, 1880.

Application filed October 20, 1880.

To all whom it may concern Be it known that I, ALMA G.MAcALL1sTEn, of Brookline, county of Norfolk, and State of Massachusetts, have invented an Improvement in Sad-Iron Heaters, of which the following description, with the accompanying drawings, is a specification.

This invention relates to improvements in sad-iron heaters, and has for its object such construction of mechanism for that purpose as will enable the oil in the heater to burn steadily in any ordinary draft either in a dwelling` or out of doors.

In this my invention I employ an oil-lamp supplied with atmospheric air to support the combustion of the oil at the wick only at the bottom of the lamp, the said air rising to the burner or point of combustion through an airspace between the oil-tank and inclosing-j acket ofthe lamp.

Surrounding the burner, and adapted to receive the usual sad-iron, is placed the ordinary holder for receiving the heel of the sad-iron. This sad-iron is provided with a longitudinal space,which constitutesaflue above the burner. I have added to this sad-iron a chimney shaped to remain in position upon the nose of the sadiron, and provided at its tip with a draft-protecting cap having outlets below its top or cover for the heat, smoke, Sac., in the chimney.

Figure l represents, in vertical section, a large sad-iron and chimney and draft-shield, to illustrate my invention as it will appear when a sad-iron is being heated. Fig. 2 is a side elevation of the holder for the heel of the sad-iron with the sad-iron removed, the chimney being set upon or fitted thereto.

The sad-iron a, having a ilue, a2, and the holder a3, for the heel of the sad-iron, are all of usual construction.

The oil-tank bis suspended by studs b2 within the j acket b3, having aninlet, b4, for atmospheric air, the said air rising through the chamber c c2, thence through holes or openings in a reticnlated distributing-plate, c4, thence into the chamber d of the burner d?, the latter having within it the usual wick-tube d3.

The holder a3 is circular at its base to iit within the prongs eas the base of an ordinary glass chimney, and its upper end is made oblong to receive within it the heel ofthe sad-iron,

(No model.)

the opening at the said heel receiving within it the cone of the burner.

The chimney f has a mouth-piece,f2, to lit over and receive within it the nose of the sadiron, the opening at the base ofthe said mouthpiece being of such size and so shaped as to fit the open top of the holder a3 whenever it is desired to mount the chimney directly upon the holder rather than upon the iron'.

The mouth of the chimney is ofy such size and shape as to fit over and cover the top of theholder. The chimney has asuitablehandle, 8, by which to handle it. At its upper end the chimney has iitted to it a draft-protecting cap, h, composed, as herein shown, of a cap-shell or piece of metal, 10, having screws or studs 5, to support within it an inverted cup, l, having extended upward from it arod, Z2, the purpose of which is, by means of the nut Z3, to hold in place on the cap the cover m and perforated ring or annulus n, through which the heated products of combustion pass oft' into the atmosphere. omitted and the annulus and cover be joined together and with the shell l0 of the cap by other usual means--as, for instance, Hanging or brazing.

The inverted cup l, extended alittlebelow the top ofthe chimney, prevents any air blown into the holes of the perforated rin gnfrom entering the chimney. All the air received in the chimney comes through the chamber c c2 and tlue a2. All the air to the burner comes entirely from the chamber c c2, and the supply of air to the burner is steady and uniform, no matter what may be the direction of the current of air outside the jacket b3.

The jacket stands on feet p, so that the air may circulate under its bottom p2 to enter the inlet b4.

Indoors, under ordinary drafts, the addition of the chimney without its cap affords an eX- tended due-space, which enables greater combustion and more rapid heating of the iron.

I claiml. In a sad-iron heater, the chimney provided with a mouth to fit over and receive the nose and extend the flue-space of the sad-iron, substantially as described.

2. The combination, with the chimney f, of a cap, h, composed oi' an outer shell, 10, eX-

It is obvious that this rod may be IOC tended down over the chimney, an inverted cup, l, suspended within said shell, with an airspace between the two, and extended below the mouth of the chimney, with an air-space be= tween it and the chimney, a cover, m, placed above the shell, and a foraminons ring, n, interposed between the cover and shell to afford outlets for the products of combustion, substantially as described.

3. In a sad-iron heater, the lamp composed of the burner, its wick-tube, the jacket and tank, and an air-chamber,c, between the jacket and tank, supplied with air only at the bottom ofthe jacket to support combustion of the oil in the burner, in combination with the sad-iron holder adapted to receive the heel of Va fluecontaining; sad-iron, and a chimney having a mouth to fit over or receive within it the nose of the sad-iron to prolong or extend its fine and increase the draft and combustion, substantially as described.

In testimony whereof I have signed my name to this speeication in the presence of two subscribing witnesses.
