Specification forming part of Letters Patent No. 138,248, dated April 29, 1873; application filed lOctober 11, 1872.
To all lwhom it 'may concern:
Be it known that I, GEORGE Hanson, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in TuyereIron or Blow-Valves for Blacksmith-Forges; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon and being a part of this speciiication, in which- Figure l is a perspective view of my improved implement.` Fig. 2 is a vertical section of the same through the center of Fig. l.
Like letters refer to like parts in each figure.
This invention relates to an improved construction of tuyere-irons, so arranged that the operator can govern the blast, as occasion may demand; and the invention consists in the peculiar devices, and their arrangement for the purpose, as more fully hereinafter described.
In the accompanying drawing, A represents a metallic chamber, cast in two pieces, al b, and secured together by bolts c through the lian ges d. The upper or top part of this chamber is provided with an opening, c, for the escape of Mthe blast from the chamber, while B is a pipe communicating with the interior of the chamber, and with which the nozzle of a bellows eugages to furnish the blast. C is a valve, which has a reciprocating motion by means of frame composed of the parts h, h1, h2, and h3, and lcver D, fnlcrumed to the outbearing E, asA
shown in Figs. l and 2.
This device is set underneath the hearth of A the forge, so that the opening c is presented to a corresponding holein said hearth.
Elevatin g or depressin gthe lever D increases or diminishes the amount of blast delivered through the opening c, as desired.
F is a valve, secured in place by the latch 7s, covering an opening in the bottom or lower part of the chamber A, by means of which entrance is had to the interior of the same for the purpose of removing ashes, cinders, dac.,
