SAD-IRON.

SPECIFICATION forming part of Letters Patent No. 308,892, dated December 9, 1884.

l Application filed February 28, 1884. (No model.y

To aZZ whom it may concern:

Be it known that I, GASPAR J. HAAs, a citizen of the UnitedStates, residing at Flint, in the county of Genessee and State of Michigan, have invented a new and useful Self-Heating Sad-Iron, of which the following is a specification.

My invention relates to improvements in sad-irons of that class wherein the body or main part of the iron is made hollow and provided with a hinged cover to receive charcoal or other fuel, the combustion of which keeps the face of the iron raised to 'the proper temperatu're.

The invention is fully illustrated in the accompanying drawings, in which Figure l is a longitudinal vertical section at x m in Fig. 2. Fig. 2 is a transverse vertical section at y y of Fig. 1. Fig. 3 is a perspective view showing* the front end of the iron and the blow- `out valve opened, also with the chimney removed to show the front standard and a part of the handle-bolt. Fig. 4L is a sectional View of the same, but with a different locking device.

Similar letters of referenceindicate like parts in the several figures.

A represents the hollow body, having an elevated stem, a, at the nose, to which hingelu gs Z1 b of the top or cover B are pivoted, as shown.

B is the front standard, which rises from and forms an elevated segment of the pipecollar c, over both of which the pipe-elbow C slips. y

B2 is a rear standard, having a stud on its base passing through a hole in the heel end of cover, to which it is secured by riveting said stud.

D is a wooden handle between the standards B B2, secured in place by abolt, d, passing through them and said handle, with a nut at the front screwed on from the inside of the pipe-elbow, which is also thereby held iirmly in place. rlhe cover is locked to the body by a lever-latch, E, pivoted at e between lugs on the rear face of the standard B2.V A spring,

. f, throws its bent lowerend, g, into a hole, h,

drilled in the` back end of the bpdy. A slight pressure on the upper end of the latch E will withdraw its end g from the hole h and allow the cover to be thrown up and forward.

A is the draft-hole in the heel of the iron,

and A2 is the blow-out hole inthe nose thereof.

G is an inclined and curved grate laid in the bottoni of the iron to support the incandescent fuel, while the ashes may drop to the bottom and be blown out through the hole A2, using a handbellows for this purpose, whose nozzle is inserted in the hole A.

H is a disk-register, pivotcd at i to the heel.` By rotating this register the draft may be regulated or sluit off at will.

I is a valve to close the blow-out. The nose of the iron is milled or bored into, leaving a iat spot across its front end, to which the valve I is pivoted by a center bolt, j. The valve is nearly triangular in cross-section and conforms to the outline of the iron at the nose when closed. A spring-bolt, J, in the upper end of the valve locks it in the closed position by its point entering a concavity inthe milled face. It will be noticed that the upper half' of the rear face of said valve is chamfered off,

as at z', also that its pivot-hole is not drilled to fit the pivot j, except at the inner end, but is reamed on a taper, as seen at i. This permits the valve to rock a little on its pivot, so that it will be loose and turn freely on its axis as soon as the lspring-bolt is moved ou`t of its socket, and thus allow the valve to be easily manipulated, the spring-bolt serving asa handle with which to swing it.

It is found in practice that under repeated reheatings ofthe metaloxidation and other chemical changes induced thereby will cause screws and nuts to stick fast, and therefore box-irons having valves or registers hung on screw-clamping pivots soon become useless by their valves and registers so fitted. This objection cannot be raised against my described construction, which allows the valve to be firmly seated when closing the blow-out, but to swing loosely when turned to open it.

I do not wish to confine myself to the particular spring-bolt shown in Fig. l for locking said valve I, for without departing from the spirit of my invention other devices may be used for the purpose, one of which I show in vertical section in Fig. 4, wherein K is a lever, pivoted at L toV lugs on the valve I above its axis, terminating at its upper end in a crank, K. The foot of said lever enters a socket or depression, m, in the nose of the iron when the valve closes the blow-out. The lower end` ICO of said lever is bent inwardly with a spring, 2. The valve I, ehamfered as at z', and havn, spirally coiled about it, and, interposed belng rea-med or tapering pvot-hole i', combined tween said lever and the lower part of the with the iron A, pivot j, and securing-bolt,

valve, keeps the latter closely seated. as and for the purposes set forth. 5 I claimp l. In a sad-iron, substantially as described, I GASPAR J. HAAS.

the combination, with the body A, having draft-apertures, as shown, of the pvoted valve Witnesses:

I, of form oorresponding to the nose or stem a H. C. VAN DEUsEN, 1o of the body, and the spring-bolt J, as and for JOHN tI. CARTON.

the purposes set forth.
