YARN-STRiPPER.

SPECIFICATION forming part of Letters Patent N0.334,904, dated January 26, 1886.

Application filed February 15, 1834. Serial No. 120,848. (No model.)

To aZZ whom it may concern:

7 Be it known that I, ALFRED SHAvnmol' the city of Troy, county of Rensselaer, State of New York, have invented new and useful Improvements in Yarn-Stripping Devices, of

which the following is a specification.

My invention relates to that class of devices which are used to free yarn from bunches, knots, and excrescences that are liable to be 13 produced on it while it is being spun. These stripping devices are usually made from a piece of sheet metal that is provided with a slit for the passage of the yarn, the edges of which slit tear off from the yarn,while the lat r 5 ter is being drawn through it, the knots or excrescences upon it.

The object of my improvement on this class of devices is to adapt the stripping-slit to better retain the yarn within it, and to combine with the stripper a means to return the yarn to the slit should it from the motion of the reciprocating yarn-guide be drawn from or run out of the slit.

Accompanying this specification, and forming part of it, there is a sheet of drawings containing three figures illustrating my invention, with the same designation of parts by letter-reference used in all of them.

Of these illustrations, Figure l is a perspective of a part of a bobbin-winder, with my invention applied thereto. Fig. 2 shows a perspective of my improved device, illustrated as removed from the winder and upon a larger scale than it is shown at Fig. 1.

3 5 Fig. 3 illustrates a cross-section taken on the line 00 00 of Fig. 2.

The several parts of the stripping device and those of the winder mechanism with which the former connects are designated by letter- 0 reference, and their function is explained as follows:

The letter F indicates the frame of that part of the winder mechanism that is illustrated; the letter T its upper cop-table, and T" its lower bobbin-table.

The letter R designates the tension-regulating pin-rod, and P the pin.

The letter A designates a preliminary stripping device, which may be used in connection with my improved device for the same purpose, if desired, and it is made of the ordinary construction having the slit a, and it is shown as attached to the cop-bonnet c.

The letter G indicates a yarn-guide, which at its end is connected with crank K, and the latter at its lower end with the rock-shaft D, the said rock-shaft being constructed to be reciprocatingly rotated so as to impart a reciproeating motion to the yarn'guide G.

The letter B designates the bobbin, and b the conical presser. I

The letter S indicates my improved stripper, which is shown as formed with the usual stripping-slit, S made in the plate E.

The letter S designates an offset made on 6 the under side of the device, and this offsetis constructed with a passage-way, S", and a setscrew, S for attachment and detachment.

The upper face of the plate E is flat, and the outer front edge thereof is curved, as ind i- 7 cated at m, and in operative connection the plate is adjusted on the yarn-guide rod with its face in a horizontal plane, the curved outer edge operating to guide the yarn back into the stripping-slit should it by any means dur- 7 ing the reciprocation of the yarn-guide and attached stripper be drawn from the slit.

The operation of my improved stripper and the parts with which it connects is as follows: The yarn having been led from the cop O, around and over the tension-regulating pin P to and through the upper stripper, A, and thence through the slit S of my improved stripper, is wound on to the bobbin B by the rotation of the latter. As the yarn-guide G is reciprocated to lay the yarn evenly on the bobbin-barrel, my attached stripper also moves with it in reciprocation, and by which motion the yarn within the slit is also moved back and forth therein in a line of motion 0 that is opposite to that of the reciprocating yarn-guide and attached stripper. This lat eral movement of the yarn while passing through the slit increases the effiiciency of the latter to remove the knots and bunches on the 5 yarn while passing through the slit. If from any cause the yarn thus moved in its passage is carried from out of the slit, on the return movement the curve m guides it back therein.

If desired, the upper stripper, A, may be IOO omitted and the yarn led directly from the tension-pin to my improved device.

1? make no claim to the form of slit herein shown with beveled edges, for any of the ordinary stripping-slits may be employed. To attach my improved device, the latter is entered on the guide-rod and secured in place by the set-screw S Havingthus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In combination with the rock-shaft D, provided with the crank-arm K,and the yarnguide rod G, connected to the crank-arm, the yarn-stripper S, consisting of the horizontal plate E, having slit S", curved outer edge, m, and sleeve 8, with set-screw S substantially as described, and for the purpose set forth.

2. The combination of acop-bonnet, ayarnstripper secured thereto, a tension-regulating rod provided with means to give tension to the yarn, a yarn-guide rod and a yarn-strip 20 per secured thereto, and a bobbin-spindle, substantially as described, and for the purpose stated.

3. The combination of the bobbin-spindle, guide-rod G, and means for reciprocating the same, and yarnstripper S, secured to said rod, with cop-bonnet c, yarn-stripper A, secured thereto, and the tension-regulating pinrod R, substantially as and for the purpose set forth.

Signed at Troy, New York, this 1st day of February, 1884, and in our presence, whose names were by us hereto written.

ALFRED SHAVER.
