W. M. vEVER-1T1; 4 TWYER FOR BLAST FURNACES No. 43,764. Patented Aug. 9, 1864.
UNITED STATES PATENT ()FFICE.

IMPROVEMENT lN Tl JYERES FOR BLAST-FURNACES.
Specification forming part of Letters Patent No. 43,764, dated Augu 911564 February 4, 1864.
panying drawings, and to the letters of reference marked thereon, forming part of this specification.
My improvement consists, first, in the removable bottom, by which means the cinders that accumulate in the tuyere can be easily removed, second, in the adjustable slide or damper andset-serew, in combination with the flat top plate and upper portion of the tuyere, by which means the blast is regulated,
as shown in the accompanying drawings.
In the drawings, Figure 1 1s a top view of said tuyere. Fig. 2 isavertical section through 3 3 Fig. 3 is a vertical section through w w. A in Fig. 1 is the flat top plate or cover of the tuyere, upon which the fuel is placed. B is a circular aperture through the said top plate near its center, for the-purpose of admitting the blast to the fuel.
O is the adjustable slide, as shown in Fig.
" 2, and is made to slide against the under side of the top plate, directly under the aperture 13. The said slide serves as a pan to hold the fuel, and also prevents the fuel from falling from the top plate through the aperture into.
the tuyere below. The slide (J also regulates the blast by means of a .setserew,'J,, which" passes through the projecting arm E, near its outer end, the lower end of the set-screw resting'upon the upper side of the arm l), whieh extends out from the slide (3, thus forming a handle withwhich to adjust the slide.
1 is the cylindrical portion of the tuyere, upon which the top plate, A,'rests, The top plate, A, is secured to the upper portion of the tuyere by means of bolts H, which pass through to said top plate, thence through ears I,' which project out from the cylindrical portion of the tuyere and secured by means of nuts screwed onto the bolt below the projecting ears I.
K is a grooved projection, extending out from the upper portion of the tuyere, for the support of the adjustable slide (3. The said groove is deep enough to let the arm D rest upon it and at the'same time allow the upper side of the arm to come a trifle below the top of the cylindrical portion of the tuyere. The said adjustable slide is kept in its proper position by means of this mortised projection and also by means ot' pieces L L on two opposite sides of the aperture on the under side of the top plate, which prevents the slide from moving laterally.
M is a piece projecting down from the end of the arm E. The said projcction'has an aperture'or mortise sutiiciently large to allow the arm D to pass through it and also to have a little pl iy up and down, so that it may not interfere with the regulating of the blast by means of the set-screw J. The adjustabe slide 0 is not-so thickas the arm D, thus allowing the upper side of said arm to fit against the under side of the flat top justback of the slide, and at the same time the slide is a little distance below the said plate, thus allowing suflicient blast for most purposes. When more blast is required,the set-screw is raised,
thus allowing the outer end of the arm to rise, I
by which means the slide or pan. is lowered from the aperture, thus giving the required draft.
0 is the conical portion of the tuye1e,to which the removable bottomB is'eonneeted at the bottom by means of beveled-pieces S S on two opposite sides of the lower portion of the saidtuyere.
'R is the removable-bottom plate, made tapering, also the two opposite edges beveled to fit the two beveled pieces S S. The said removable bottom is forIthepurpose of being removed for the discharge of the cinders which accumulate in the tu'yere.

Having thus fully described my invention, the arm E, and the set-screw J, substantially v what I claim, and desire to secure by Letters as and for the purpose set forth.
