IMPROVED TUYERE.

' an air-chamber in su'ch a manner that it Will become heated before escaping from'the tuyere to the iire ofthe furnace, whereby a much better consumption ot' the products of combustion is secured, and thereby a greater amount of heat generated, than by the ordinary arrangement of air-blasts for such furnaces. l

In the accompanying plate of drawings my improvement is illustrated, Figure l being a view of the tuyere, showing a Water-reservoir in connection therewith, as well` as my improved vconstruction or arrangement of an air-chamber for heating the blast before escapy ing fromthe tuyere; and Fig. 2 a central vertical section through the tuyere and air-chamber with the connecting-pipe between the two for the air-blast.

Similar letters of reference indicate vlike parts. A in the drawings represents the tuyere, which maybe made of any of the ordinary constructions therefor, but which in the present instance has its rear portion, B, made hollow, to allow a circulation of water or other cooling medium through the same from a reservoir, c, suitably connected therewith through pipes D and E, the one, D, for the passage of the water, and the other, E, for the escape of the steam generated by the heat of' the tuyere from the water.

The tuyere is placed in a horizontal position, with its mouth or orice E just above the tiregrate of the furnace, the rear end of the orifice Gr, through the center of the tuyere, being connected by an elbow pipe or tube, H, with the under side ot' an air chamber or box, I, placed over the tuyere, to the rear side ot' which, at or nearits top, one end of a pipe, J, is connected, that at its other end is secured 'to the apparatus used for producing the air-blast.

From the above description it is plain to be seen that the air-blast, in passing to the tnyere through the air chamber or box I must necessarily become heated thereby, and, from the heat of the furnace-tire itself, independent of the tuyere, wherebythe consumption ofthe products ot' combustion of the furnace is greatly lncreased, and a consequent greater amount of heat generated than by the ordinary mode of' passing the airblast directly through the tuyere, the importance of which result is apparent to all conversant with the use and op7 eration ot' 'blast-furnaces, forges, Sac.

I claim as new and desire to secure by Let ters Patent- The tuyere A, consisting of the water cham ber B, connecting-pipes D E, water-reservoir C, elbow-pi pe H, air-chamberl, and pipe J, and having an opening, Gr, combined and operating substantially'as and for the purpose represented and described.

The above specification of my invention signed by me this 27th day ot' February, 1866.
