Tia/22w S Clark,
' BumsM/msfi/ym PATENTED AUG 8 1871 [ill 612307 UNITED STATES THOMAS s. CLARK, or CHICAGO, ILLINOIS.
.- IMPROVEMENT IN TUYERES.
Specification forming part of Letters Patent No. 117,744, dated AugnstB, 1871.
To all whom it may concern:
Be it known that I, TH'OMAS S. CLARK, formerly of Lena, in the county of Stephenson and State of Illinois, but now residing in Chicago, county of Cook and State aforesaid, have invented certain new and usefullmprovements in Blacksmiths Tuyeres, of which the following is a specification:
Figure 1 represents a plan View of so much of my improved tuyere as is necessary to illustrate my invention, with a portion of the outside casing broken away to show the interior; Fig. 2, a vertical longitudinal section through the tuyere and blast-pipe; Fig. 3, a View, in perspective, of the truncated tubular ring and ball detached.
This invention constitutes an improvement on what was formerly termed blacksmiths forge, but which is properly a tuyere, for which Letters Patent were granted to me December 29, 1868, No. 85,283, and the subject-matter is clearly designated in the claim hereinafter made.
In this instance, the blast passes through the pipe A into a blastchamber, B, which is of an annular shape, and is oval in cross-section instead of being rectangular, as in my former patent above mentioned. This construction I find preferable in producing a uniform current of the blast. A partition, I), in the chamber at the mouth of the blasttube divides the current so as to cause it to sweep round all sides of the chamber, a hand-hole, 0, in the bottom of the chamber allowing the escape of any ashes, &c.,which may work into the blast-chamber through the carelessness of the workman or otherwise. This hand-hole is oval in shape, and, ordinarily, is closed by a plug having a button, 0, on its inner side, by which to lock the plug in place, this being done by inserting the plug and turning it round until the edges of the button are locked onto the sides of the opening. Instead of the dome shown in my former patent, which had a cup consisting of a ring united to the dome with a sharp re-entering angle, the dome and ring of this improvement are formed in one continuous curved piece, which forms the cover of the blastchamber. This mode of construction I find to be useful in directing the blast properly upon the fire. The inner side of the blast-chamber is so curved as to form a tubular opening, D, for the escape of ashes, cinders, 85c. Aflanged tubular ring with a flaring top is placed on the top of this tube and extends upward nearly to the level of the bottom ring of the upper part of the blastchamber. This chamber is cast in two horizontal sections, as shown, which are clamped together by bolts passing through said flanges.
The tubular ring E and ball F are fitted to their bearings in the blast-chamber casing before the sections are clamped together, and are then sccurely held by the same bolts which secure the sections in place. The lips c on the ring are de-, signed to hold it down securely in place, as they abut against the casin g and prevent the ring from rising. By this means the tubular ring and ball can readily be removed. The ball F, which forms the cover of the tubular ring, is pivoted to rock in bearings, of which the rod f is an extension. By turning this rod the ball is at once cleaned of ashes, cinders, &c.
I claim as my invention The combination of the blast-pipe, the blast- I chamber, the detachable ring, and the ball, all
these members being constructed and operating in combination, as hereinbefore set forth.
THOMAS S. CLARK.
