IMPROVED TUYERE. l

.lO ALLVIIOM ITMAY CONCERN:
Bc it known that I, JIIN- W. CRANNELL, of Yorkville, in the county of Kalamazoo, and State of Michigan, have invented a new and useful improvement in Tuyeres for blacksmiths forges; and I do hereby declare the following to be a full, clear, andexa'ct description of the same, reference being had to the annexed drawing, making a part of this specification, in which- Figures 1 and 2 are brokens'eetional views, at a right angle with each other.
Similar letters ofrefcrcnce indicate corresponding parts in both-figures.
My invention has special reference to a peculiar arrangement for adjustment, by which some definite number of changes may be made in the arca of the openings, through whichthe windfissues to the fire, besides operating in a manner to collect and clear away small clinkers and ashes, which collect and obstruct said wind-passages; and the better to enable others skilled in this branch of mechanism to construct my inventiomI will now proceed to describe it.
A represents two sides of a wind-chest, open en top, into which the wind is forced by the bellowsor fan,
through a nozzle inserted usually ator about the point a. This chest is commonly made of a square form,`
tapering downward, and is flanged, as atB, to rest upon the masonry M of the forge, in, which an open space, D, for an ash-pit, is formed immediately underneath. Two sides of the cap are exhibited at C. It is placed, over the windchest in the form of a hollow truncated pyramid, withta square opening on top, beaded, as atb, a to resist the actionof the fire. The four inner sides of this cap form the outer boundaries ofthe narrow windpassages, of which `two are seen at e. To form the inner walls of the wind-sheets, in Aa manner susceptible of e'asy change of area space, to s nit the nature of the work to be done, I employ what I term an irregular recessed cylinder," E, which is keyed on a shaft, S; said shaft being hung in bearings formed in'ears or lianges f on the wind-chest, and extending, at one end, through the masonry in front ofthe forge, where it is generally furnished with a crank-arm, i', and gauge-platc,.n, having a series of holes arranged concentrica-lly, bythe means of 'which the irregular cylinder may be turned partially around and secured `at some other desired position.
Tapering recesses, indicated at R, of a size and form to correspond with the opening in the cap C, are sunken within the periphery of the-cylinder, the outer corners of two sides of said recesses being determined by circular l arcs, of different radius, struck from the centre et' rotation, as may be` clearly seen by the dotted lines at 1, 2,
3, and 4. To facilitate the removal of the cap, and help te steady it in place, I usually slot two sides of the cap to permit it to pass over the shaft. v
The cap is sunk in the usual material et' which the forge-hearth is constructed, and anything having a tendency to choke up the wind-passages will, on stirring the fire, naturally fall into enc of the cups or recesses R, and will be emptied (on drawing back the slide j) into the ash-pit below, when the irregular cylinder is turned for that purpose, or for the purpose ot'changing the size of the windpassagcs, by moving another recess under the opening inthe cap.V If desired, the wind-chest cap may be a hollow truncated cone, in which case, as theV opening would be circular, thc centre of the cylinder would be spherical, to conform, subject, however, to the same irregular formation of surface, in connection, perhaps,- with some shaping of the interior of the cap, so that to whatever station the eccentric spherical cylinder may be set, the intervening wind-space between it and the cap, whether straight or curved, may bc equal and parallel all round.
I disclaim the arrangement. of the wind-chest and its cap; but what I do claim, and desire to secure by Letters Patent, is this: l
I claim the arrangement and combination ofthe irregular recessed cylinder E and shaft S with the windchest A and cap C, substantially in the manner and for the uses herein described.
