WILLIAM SHARP, OF MILLPORT, NEW YORK.
IMPROVEMENT-IN BLACKSMITHS TUYERES.
Specification forming part of Letters Patent No. 41,940, dated January l2, 1864.
To all whom it may concern.'
Be it known that I, WILLIAM SHARP, of Millport, in the county of Chemung and State of New York, have invented a new and useful Improvement in Blacksmiths7 Tuyeres; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which Figure 1 is a plan View of the fire-bed, showing the blast-openings expanded to their fullest extent; Fig. 2, a vertical section of the blast-chamber. Fig. 3 is a plan view showing the cut-oft' or graduating partition with the revolving disk removed. Figs. 4 and 5 represent the disk and graduating-plate together, showing different degrees of the blast area.
Like letters designate corresponding parts in all of the gures.
As represented on the drawings, A is the nozzle of the blast-pipe, which enters the chamber B, Fig. 2, directly beneath the iirebed, which consists of a stationary plate, C, having openings, as shown in Fig. 3, and a disk, D, provided with apertures corresponding in position, but of different form, which is capable of revolving far enough to open or close the apertures of the plate below it.
The bed-plate C and disk D have a small central aperture, e, in common, which is never closed, but supplies air to the center of the re, and the construction of the openings f f ff in the bed and g g g g in the disk is intended to regulate the fire, not only by shutting off a portion of the wind supplied from the chamber B through these openings, but by diminishing the area of the re by circumscribing its dimensions from all sides to the center, thereby enabling the operator to have a fire of small compass, but of equal intensity with a larger one, a result that is completely under his control, and of much importance in the greater convenience which it affords in heating small irons, and also as effecting an important saving in the fuel used.
The openings f in the bed-plate are of irregular form, as shown, their sides and ends being composed of obtuse angles so disposed that the boundaries of the apertures g of the disk (which have one straight side and one consisting of two obtuse angles) shall in turning on its bed first close those portions of the openings f which are farthest from the center, and the width of the apertures f being least at the part nearest the periphery the area may be considerably reduced without much diminishing the quantity of wind which passes through.
rIhe openings are arranged around the central one, e, at regular intervals and radiating from a common center. Itis obvious that the form of these apertures may be materially modified, and that a greater or` less number may be employed and still produce the same effect. Therefore I do not confine myself to the particular form and number represented.
A pin, t', from the disk works in the slot 7c of the bed-plates and limits the extent of rotation of the former to the amount required to open and close the holes. An air-space is formed between the bed and disk, which prevents the heat from destroying them.
I am aware that numerous methods of regulating the blast of forges have been devised, all of which, so far as I am aware, act by diminishing or weakening the blast without proportionately contracting its area, and therefore fail to accomplish the object of my invention viz., diminishing the area of the fire without (unless desired) diminishing its intensity.
It is important that the heat of the central portion of the fire should be kept at its maximum; hence l do not diminish the supply of air through the central orifice, e, but gradually contract the surrounding orifices toward the center, causing the fire to subside at its outer edges only.
What I claim as my invention, and desire to secure by Letters Patent, is-
The combination and arrangement of the partially-rotating disk D and stationary bedplate O, provided with the unvarying opening cand variable openings g for their equivalents, with the blast-pipe A and blast-chamber B, substantially in the manner and for the purposes shown and described.
In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
IVM. SHARP.
