TUYERE-IRON FOR BLACKSMITHS FORGES.

sPEcIF'IcA'rIoN forming part of Letters Patent No. 264,414, dated September 12, 1882,

Application filed January 28, 1882.

- to reference being bad to the annexed drawings,

- making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a longitudinal section of my invention. Fig. 2 is a cross-section, and'Figs. 3 and 4 are detail views of the tuyere -iron.

This invention has relation to tuyere-irons and blast-connections for blacksmiths forges; and it consists in the construction and novel arrangement of the sliding wind-box inclosed under the grate, and of the under-recessed tuyere-plate having beveled grate-bars separating converging wind-passages, all as hereinafter set forth.

In the accompanying drawings, the letter A designates the hearth of the forge, having a seat, B, for the tuyere-iron (J, said seat being provided with a wind-aperture, D, over which the tuyere-iron is located.

E represents an incasement or slideway under the tuyere-iron, having the lateral blastpipe F and theend openings, G, in the base, as indicated in the drawings.

Within the incasement E is located the sliding wind-box H, which is provided with an operating-handle, K. In the side of thiswindbox is a wind-aperture, L, and in its top is a blast-opening, N. The slide-box is usually made without a bottom, the base I? of the in- 0 casement serving to close the box on the under side.

The tuyere-iron Gis designed to rise by inclined side walls, S, to a center, in which the blast-opening T is made. Under this blastopening, and communicating therewith, is formed in the under side of the tuyere-iron a (No model.)

circular concavity or wind-recess, W, of larger diameter than said blast opening. Transversely'arrangedin this recess Ware the gratebars V V, having inclined outer walls or sides, 2, running to curved upper edges, a, and separatingthe wind-recess VVinto converging windpassages 11, asindicated in the drawings, which are designed to concentrate the wind divided equally by the grate-bars, forminga powerful blast at the top of the grate.

When the blast-box H is moved to one end of its slideway its wind-aperture L will register with the inner opening of the blast-pipe F and the blast-opening N in its top with the wind-aperture D in the seat of the tuyere-iron,

so that the wind will be put on when the bellows is actuated. When the wind-box is moved to the other end of its incasement or slideway the wind is cut off at the side of the box and under the grate at the same time. The slide-box also moves over the opening G in the base of the slideway, allowing the ashes which have accumulated in the box to fall through.

Having described this invention, what I claim, and desire to seoureby Letters Patent, 1s

1. The combination,withthe inclosing slideway under the hearth, and having blast-pipe and wind-aperture, of the sliding Wind-box,

having in its side a wind-aperture and in its top a blast-openin g, substantially'as specified.

2. The combination, with a tuyere-iron having grate-bars, and a slideway having windopenings and ash-discharge, of the sliding 8o wind and ash box, substantially as specified.

3. A tuyere-iron having a raised central opening, T, under recess W, and transverse grate-bars V, having inclined sides 2, substantially as specified. 8 5

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
