SAD-IRON HEATER.

SPECIFICATION forming part of Letters Patent N0. 227,081, dated April 27, 1880.

Application filed September 520, 1879.

To all whom it may concern:

Be it known that I, HARVEY L. WELLS, of Evansville, in the county of Vanderburg and State of Indiana, have invented a new and Improved Sad-Iron Heater, of which the following is a specification.

Figure 1 is a front elevation of the device, partly in section. Fig. 2 is a plan of the same with part broken away. Fig.3 is a transverse sectional elevation on linem a, Fig. 1. Fig. 4 is a sectional elevation, showing the valve and certain other parts enlarged.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish a simple, safe, and efficient device in which light oils may be used as fuel for heating sad-irons for domestic use, or for the use of tailors, dress-makers, &c.

The invention consists, essentially, of an iron box divided longitudinally into two chambers, the lower being the combustion-chamber and the upper the heating-chamber.

The heating-chamber is divided by vertical partitions into several receptacles for the sadirons, each one of which is open in front for the easy entrance and withdrawal of the irons, and has an opening in the top, through which the handle of the iron may protrude to keep cool. Between these receptacles are narrow openings or chimneys for the upward passage of heat and gases. This upper chamber may be detached at any time and the rest of the apparatus be applied to the purposes of cocking, the cooking utensils being set on top of it. These chambers rest on suitable upright supports, from which rise at the ends of the device the supports of the oil-reservoirs, that set higher than the chambers and at a safe distance from them. From these reservoirs descends a main pipe, from which branch at right angles several other tubes to supply oil to the burners in the combustion -chamber. The flow of oil to the burners is regulated by valves, and the burners have novel auxiliary devices, all which will be herein after more fully described.

In the drawings, A represents the combustion-chamber B, the heating-chamber, divided into the receptacles O by the partitions a.

These receptacles O are open in front, and have openings b in their tops for the projection of the handles of the irons. D are the flues or chimneys between and at the sides of the receptacles G,connect1ng with the combustionchamber A. In the closed front of the combustion-chamberA are the openings 0 through which air may be admitted to aid in the com bustion of the generated gases, and which also serve as inspection-holes, through which the flame of the burners may be observed to be regulated, if desirable.

E are the standards supporting the device. F are the supports of the oil-reservoirs G. H are the pipes leading down from the reservoirs G, through which pipes H the oil flows into the tubes I, that extend into the combustionchamber A. Within these tubes I are designed to be the conical valve-seats d, with small orifices for the oil to flow through, and through the free ends of the tubes are entered the pointed valves K. that regulate the flow of oil. Projecting upward from these tubes 1 are the burners L, provided with small bores reaching downward into the tubes I.

M is a perforated cap set over the burner L to spread the flame, and this cap M is sup ported by a rod, j", that conducts heat to the tube I, to convert the oil therein, or a portion of it, into vapor.

N is a cup suspended by a tube, g, below the burner L, on the opposite side of the tube I. IVhen the device is to be put in operation a little oil is permitted to flow into the cup N, where it is set on fire, that it may heat the tube I and generate gas therein that shall escape at the orifice of the burner L, where it will be lighted for the purpose of heating the sad-irons, and as the work continues the heat reflected upon the tube I by the cap M, and conducted by the rod f, is found to be sufficient to vaporize the oil passing through the valve-seat d and convert it (the oil) into a gas, that escapes and is burned at the burner L, thus supplying all the heat that is desired.

On the bottom of the sad-iron receptacles are circular plates 0, whose object is to deflect the flame and thus create an upward draft, so that sufticient air may be drawn in through the opening 0 to cause the complete combustion of the gases and the consequent absence of soot.

P are the handles by which the device may be moved.

These heaters may be made of any size to heat one or more irons, and of such shape that when the upper chamber, B, is removed the top of the combustion-chamber A will accommodate the cooking utensils ordinarily used. These heaters are constructed to be fastened on a platform or board, or on the ironing-table, and are found to be well adapted to the work for which they are designed.

I am aware that burners and valves some what resembling mine have been used before; hence I do not broadly claim them; but,
