HENRY BRANCHLER, OF GREENSBURG, PENNSYLVANIA, ASSIGNOR OF ONE- HALF TO JAMES WIMER, OF SAME PLACE.

BLACKSIVIITHS HEARTH.

SPECEFXCATION forming part of Letters Patent No 337,735, dated March 9, 1886.

Application tiled October 12,1885.

To all whom it may concern:

Be it known that I, HENRY BRANCHLER, a citizen of the United States, and a resident of Greensburg, in the county of lVestmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Blacksmiths Hearths; and I do hereby declare that the followingis a full, clear, and exact description of the invention, which will enable oth- Ic ers skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a vertical sectional View of my improved blacksmiths hearth. Fig. 2 is a similar view of the same, taken at a right angle to Fig. l. Fig. 3 is a side view of the tuyere, showing parts ofthe hearth broken away, and Fig. 4 is a horizontal sectional view on line :r as,

Fig'. 3.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to blacksmiths7 hearths, and more especially to the tuyere part of such hearths, and it consists in the improved construction and combination of parts of the same, as hereinafter morefnlly described and claimed.

In the accompanying drawings,'thc letter A indicates the brick-support for the hearth, and B indicates the bowl, in which the fire is kept, and which has the aperture O in its middle. The bowl has a neck, D, formed around the aperture, which neck lits into a vertical chamber, E,which is provided at its lower end with a slide, F, and which has the blast-pipe G entering its side near its upper end. Two rockshafts, H H, are journaled in the upper end of this chamber immediately below the neck 4o of the bowl, and have two wings, I I, projecting into t-he chamber and nearly closing its upper end when placed horizontal, the rockshafts bearing against the walls of the chamber. rIhe roclcshafts are provided at one end with cogged segments J, meshing with each i other, and one shaft is extended and provided with a suitable handle or lever, K, for rocking it.

It will now be seen that as the rock-shafts 5o are turned to bring the wings to point down- Sera. No. 179,593. (No model.)

ward the aperture between them will beincreased, allowing a greater quantity of blast to pass up-th rough the tire, and when the wings have been turned sufficiently down, so as to occupy a vertical position, or nearly so, the cinders from the re may fall down into the chamber, and be emptied out by drawing the slide out at the bottom of the chamber, so that the fire may be renewed or the cinders emptied out without disturbing the irons which rest 6o in the lire.

The slide in the bottom of the chamber will prevent the blast from escaping through the aperture in the bottom of the chamber, andV the chamber will serve to equalize the blast as it enters the chamber and lls the saine before ascending through the aperture at the top of the chamber, so that if there is any inequality in the blast it will not be felt in the iire, the chamber serving as a store-room for the blast, 7o from which it may pass into the tire.

The blast may be regulated by opening or closing the wings or gates upon the rock-shafts, while still keeping theirinner edges sufficiently close together to prevent the cinders from falling through the aperture between them, and when the tire gets dull from accumulation of cinders they may be dumped down into the chamber by opening the gates under the aperture of the bowl, when the cinders, which will 8o be immediately above and upon the aperture in the bowl, will drop through the aperture, while the live coal and the coal which has not yet been consumed will remain in the bowl,and may be raked toward the middle of the same. In this manner the tire may be kept up continually without any necessity for raking the tire ot'f from the hearth for the purpose of cleaning the aperture in the bowl, and the iire may be relieved from cinders without even removing 9o the irons from the tire.

It follows that this hearth or tuyere may be used in a stationary hearth as is generally found in a blacksmiths shop, or it may be adapted to .iit into the several forms of portable hearths, my improvements beingindependent of the means for creating the blast, as well as of the shape of the bowl and its support, being adaptable to any construction of bowl and support.

IOO

I am aware that it is not new to provide a blaeksmiths tnyere with pivoted gates' 'or doors by vmeans of which the draft can be regulated, and I do not claim such construction, broadly; but

I claim and desire to secure by Letters Patent of the United Statesl'. Inahlaeksmithstuyere,thecombination, with the bowl having t-he aperture in its iniddle, of two downwardly-opening gates having cogged segments upon their pivotal shafts meshing with each other, said gates being so arranged that their edges always approach each other directly underneath the middle of the aperture in the bowl, as and for the purpose shown and set forth.

2. In a blaoksniiths tuyere, the combination of a bowl having an aperture at its iniddle surrounded upon its underside with a neck or ange, a downwardly-extending chamber having vits upper end fitting' upon the neck, and having the blast-pipe entering its side near the upper end, and having an aperture at its lower end, two rock-shafts journaled in the upper end ofthe chamber, bearing against the sides of the chamber, and having `vWings upon their inner portions for closing the chamber, and having eogged rsegments upon their shafts meshing with each other, and means for rocking` them, and a slide covering the aperture in the bottom of the chamber, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto aixed my signature in presence of two Witnesses.

HENRY BRANCHLER.
