IMPROVED mom son rtmrtnmc SKIRT-WIRE.

TO ALL WHOM .IT MAY CONCERN:

Be it known that I, JOHN H. MONK, of BrooklymE. D., in the county of Kings, and State of New York, have invented,'madc,. and applied to use a certain new and useful improvement in Means for Tempering Skirt- Wire, tire. and I do herebydeclare the following to be a full, clear, and exact description of the said invention, reference being had to'the annexed drawing, making part of this specification, wherein- Figure 1 is a section longitudinallyof the tempering-trough, and

lijigure 2 is a transverse section of the same.

Similar marks of reference denote the same parts. I l

In tempering skirt-wire, it is usual to employ a bath of melted lead, across which two metal bars are placed, and the wire led beneath these bars. The constant rubbing of the wire as it is drawn along wears notches speedily in these bars, and when a join or inequality in the wire'comes to such'notch itis very liable to catch and be broken. Besides this, where a. wider wire is'drawn along in a place where a notch has been worn bya narrower wire, oize. edge enters such notch and. the other does not, and a twist is given to'the skirt-wirein tempering which renders a separate straightening operation indispensable. It also is important thatthc means for keeping the wire down into the-melted metal be adjustable, in order that any variation in the depth of melted metal may be accommodated, and that the warping or twisting of the pot underttheheat'may be easily compensated,- in order that the wire, in being drawn along, may be exposed to exactly the heat required.

The nature of my said invention consists in a pair of adjustable grooved rollers applied in such a manner to the bath of melted metal as to overcome all the difiiculties aforesaid, and insure the perfect tempering of the skirt or other wire, as hereafter specified, the said rollers revolving by the contact of-the wire.

In the drawing, a is the pot forming the tempering-bath, the same being properly set, andhca'ted so as to fuse the tempering-metal. b and c are grooved rollers, each of which is set in bearings 01 d, that are within stationary slides e e, and are adjustable by screws ff. Each groove in the rollers band 0 is widerthan the p ,widest skirt-wire that is to be tempered on the machine, and the rollers are placed near'the ends of the bath,

their lower sides being below the surface of the melted metal. The skirt-wire is drawn. through the melted metal to temper the same, and the rollers 25 and a keep it down below the surface of the metal, and in-a straight position between one roller and the other.' The ends of therollers being set in adjustable bearings, allow of their being raised or lowered, so as to immerse the wire to be tempered more or less below the surface, according to the amount of heating required in the tempering, and one end of the rollers may be immersed more than the others where two sizes or qualities of wire are being run through at the some time, the journals fitting loosely in the hearings to allow of this slight diagonal position of the rollers, so that they will revolve freely by the contact of the wire being tempered.

Several wires can be run through at thesame time, and there is no liability for the wire to become caught or broken, and there is no stationary surface for the wire to run over, which would be worn into notches or grooves.

In order to keep the rollers free from dirt or any accumulation of dress, I make use of scrapers g, hung on the cross-shafts 7t, and by having a separate scraper to each groove-they act much better in removing any obstructions, and if the obstruction is not removed by coming into contact with the scraper the'iirst time, that scraper will rise and not lift the other scrapers.

What I claim, and-desire to=seeure by Letters Patent, is-' A pair of grooved rollers, adjusted substantially as specified, in combination with the pot or bath for-melted metal for tempering wire for skirts, 860., in the manner set forth.

' In witness whereof I have hereunto set my signature this twentieth day of July, 1866.
