'IMPRDVED WATER-TUYERE.

' The Schedule referred to these :Letters Patent and making part of tli'e `lame' To all whom tt may concern.-

Beit known that I, EDWARD Dnvmsom of Bos' ton, in the county of Suffolk, and State of Massachusetts, have invented a new and improved Water- Tuyere; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to improvements in watertuyeres designed to provide a simple, cheap, and ei- Figure 4 represents a plan of the same, in dotted lines it also shows the pipe-connections; and' Figure 5v representsa plan of the inside of a cap, usedfor closing the end of th'e tuyere when detached from the water-tank.

The tuyere A is made f'ith a large hollowlspace, B, and a screw-threaded opening at the end O, for the rcception'of the air-pipe E, which screws in tightly, making a water-tight joint,'-and consists of a short section, alittle longer ,thanthe tnyere, screw-threaded at the end F, where it is jointedto another section,

G, by a. thimble, H. This. section` G is an'anged the proper length to extend, when connected to E, through the water-tank I, to the opposite side, where it is screw# threaded, and a nut,`K, screws up on it against the side of the water-tank, thereby drawing the open end of the tuyere snugly into an annular groove in the y ters Patent, is-' y 1. The combination and arrangement of the. tuyere A, pipe-section E, section G, tank and tightening-nut opposite side of the tank, to make a water-tight joint, in which any preferred packing may be used.

The pipe from'the blower may be connected to the end of this section behind the nut K.

In order to adapt this tuyere to be detached from the .water-tank and used separately, as is 'sometimesv required in heating articles not adapted to be heated -by a fire close by the tank, I provide ametallic cap,

L, for closing the end of the tuyere, with an an` nular groove, M, for the reception of the end, two holes, N, for the connection of the water-pipes, and a 'central hole, O, for the wind-pipe' E, and this oapvIv place on the pipe E, which is detached from the sec-4 tion G, and vusing the nut K, I screw it up tightly against the end of the tuyere, as shown in dottedA lines, iig. 4, and then, making any suitable connections of water-pipes, connected to the tank or otherwise, and a wind-pipe, the tuyere may be ,used in advance of the tank, as required.

P represents,V in dotted lines, supply and exhaustwater-pipes, and y Q, a wind-pipe. l

When used'in this way, the holes in the water-tank v for the wind-pipe are closed in any preferred way.

Having thus described my invention, What I claim as new, and desire to secure by Let K, substantially as specified.

2. The combination and arrangement of the tnyere A, pipe-section Il, cap M, and nnt'K, when the said cap is arranged for theattaohnient of water-pipes P, substantially as specified.

The above specification of my invention signed by me, this 7th day of August, 1869. V
