Letters Patent No. 110,617, dined January s, 1811.

Y The Schedule referred to in these Letters Patent and making past of' Vthe same.

To whom it may concern:V Be it known that we, THEoDoun T.' Auer and JOHN A. V. SMITH, of Manchester, in the county of Hillshorbugh'in'the Stpte of New Hampshire, have invented certain Improvementsin Fliers for Spinning- Machines, of which the followingis a specification.

The object of this intention" is to supply a want that has for some time existed, by constructing the dier so that it shall be light, of the proper form to ad- Vmit the present-shaped bohbjns', strong and durable,

and at the same time not fail .to give to the thread the amonntof twist desired or` necessaryfind It consists in the eonstr'uctionof the ilierasa whole,

' as hereinafter described, so that therobject of the inveution 'shallb'e obtained, and :the iiier made more durable, without essentially increasing its co'st'. In the drawings- Figure lis aside view of the Hier, showing the slit :ind the thread; 'i

Figure 2 is a sectional -vieivf'of the sam'; and Figure 3 is a transverse seetional view through one of the arms at'ab. v i

A is the `upper shoulder-piste or nose, having the sectiv aholioiv tube with;A the section B' above it, which is extension of theI tube B, butsmalier in outsidediameter, and has slots or mortises D on the two opposite sides. Iheaprture c, at the top .of the flier, is of the' `sanief- "taeter"l for a little distance -into section B of the nose-piece, when it beg'iue to enlarge to the under and inside of the shoulder-piece or nose A, where the diameter is considerably increased, and where it is made to intersect a groove in the shoulder-piece, and conduct thoroving or thread into the slit c' of arm O. This nose'pieee is formed j'of metal, preferably of cast-steel, and having angniar and projecting sockets g g to receive the arm G.

. A' is the bottom piece of inthe saine inetai as the nose or shoulder-piece A, and has similar projecting angular sockets g g, for the same purpose.

Arms O 0 are made from teel tubes, and bent in the form shown in figs. 1 and 2, and secured in the bottom and nose-pieces in sockets g g by means of brazing or soldering, the holes in the sockets being bored upon an angle, as seen in iig. 2, where the steel v tubes O are inserted and brazedfast.

In one arm is shown the slit o", in whieh is placed the thread or rpvigf, 'andis a continuation of groove e in shoulder or nose-piee A. The slit e" continues to, or nearly to, the middle of .the length of 'arm O, wheteit terminates in an angular eye, d, and where the tlnjead is delivered to the bobbin in the usual way.

. The steel arm at eye d cause of the constant action ai' the passing thread bearing upon it in beingdelivered to the hobbn and, to protect the arnrfronr being )vorn out and becoming useless by such wl so soopa second or auxiliary .piece of steel tubing, En'hrger in diameter, is placed around arm G, and brazed fast thereto, extending froml oto o on said ann Q, as seen in figs. 1 and 2.

At points o o thisaufriliary piece of tubing is reduced to the size of arm G, making a cleanand smooth finish.

In order to give the necessary twist to the thread when the thread is nnevehly drawn, sect-ion B' of the nose-piece A is made with the-opposite openings or mortise D, and the threadf is passed into the opening c at the end of section* B', and out through one opening, D, around thegoutside of B', and into the oppositeV opening-"D, then down through the aperture c in the nose-piece A and groove c' into the slit of arni C to the delivery-eye d, as seen in gs. 1and2, where it makes its exit and goes to the bobbiu.

This construction insures an even twist iu the thread, whether equally drawn or not, as the bite made by passing the thread through the opening D, and around B', into the opposite opening D insures a twist in all parts of the thread evenly and alike, thus making 'a very perfect twist in the` thread.

Having thus described iour invention,

What we'claim, and wish to secure by Letters Patent, is

As au article of manufacture, the abovedeecribed dier, composed of the pieees A.aud A', having angular 4sockets g g, tubular and nent arms (l C, auxiliary, piece E, and section B', provided with openings D DT all constructed in the muuu er and for the purpose described. 55p
