ABEL T. ATHERTON, OF LOWELL, MASSACHUSETTS.

IMPROVEMENT IN TUYERES.

Specification forming part of Letters Patent N0. 55,222, dated June 5, 1866.

To all whom'z't may concern:

Be it known that I, ABEL T. ATHERTON, of Lowell, in the county of Middlesex and State of Massachusetts, have invented new and usef ul Improvements in Tuyere-Irons; and I do hereby declare that the followin gis a full and exact description thereof, reference being had to the accompanying'drawings and to the letters of reference marked thereon.

The nature of my invention consists in the arrangement and construction of lthe watercistern, tuyere-iron, and expansive packing, as hereinafter set forth.

To enable others skilled in the art to make and use my invention, l will proceed to describe its construction and operation.

Figure I 'represents a side elevation of a forge with water-cistern and tuyere-iron attached. Fig. 2 represents a vertical section of the water-cistern and tuyere-iron.

a represents the forge, b, the water-cistern c, the blast-pipe; d., the end ofpipe attached to the bellows; c, the expansive packing; j', the tuyere-iron; g,the fire-box, h,thespacefortl1e water around the blast-pipe.

The lire-box g being filled with coal and fire applied, the water-cistern b being lled with water, the blast put on at d, produces combustion of the coal and communicates heat to the tuyere-iron f. The water being constantly changing from the cistern b to the space h in the tuyere-iron f, a warm temperature of water is kept up when the forge a is in operation, which prevents freezing in cold weather. In the ordinary manner, Where the tuyere-iron is connected with the water-cistern by means of pipes, the water becomes frozen in the tuyereiron and pipes. No escape being afforded to the steam which is generated in consequence of re being applied to the coal in the forge, there is frequently an explosion and bursting Y of the tuyere-iron, which is 'attended with great danger to those atwork lat the forge. This danger is entirely remedied by the construction of the tuyere-iron f of my invention, inasmuch as the tuyere-iron f, having a taper Water space or chamber, h, tapering much larger from its smallest point at the forge a to its largest point, where it is connected to the cistern b without the aid of the common intervening straight pipes, which prevent, when the water in them congeals,the return of the Water and steam to the cistern allow the water, when freezing, to expand into the cistern I), and upon the application ot' heat to the tuyere-ironfthe ice is again converted into water, and has free escape from the tuyere-iron finto the cistern l) without any of the danger attending the working of the ordinary water tuyere-iron. In addition to this the expansive packing c allows the blast-pipe c, which passes through the cistern b and connects with the tuyere-iron f, to expand and contract under the action of heat and cold without injury to the cistern b or tuyere-iron f, and also without allowing the water in the cistern b to escape at the tuyereiron f, where it is attached to the Water-cistern b, and also around the blast-pipe c. Therefore the advantage of the water-cistern b, expansive packing e, and tuyere-iron f, with water-space h, over the common supply-pipes is of vast importance to the smith in its utility, convenience, cheapness,l and safety.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination of the cistern b, tuyere-iron f, pipe c, and packing e, constructed and arranged substantially as set forth.

ABEL T. ATHERTON.
