UNTTE STTES PATENT YARN CLEANING DEVICE.

SPECIFICATION forming part of Letters Patent No. 390,326, dated October 2, 1888.

Serial No. ?,906. (No model.)

To all whom, it may concern.-

Be it known that I, HENRY F. \VEST, a eitizen of the United States, residing at Gloucester Jity, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in a Yarn'Gleaning Device, of which the following is a specification.

My invention has relation to certain novel features of improvement in the construction of a device for cleaning yarn or other fibrous material of the type forming the subject-mat ter of an application for Letters Patent filed by me on the 13th day of September, 1887, and serially numbered 249,543.

Theprincipal object of my present invention is to provide a device consisting of two longitudinal bars each provided with a series of knives disposed at an angle,and with supporting-seats and L-shaped depending arms at right angles to said bars, the device being constructed so that it may be quickly set by hand for the performance of its functions of cleaning or removing mote, fuzz, or small particles from fibrous material in its passage between the knives of the device.

The nature of my invention will be more particularly understood taken in connection with the accompanying drawings, wherein I have shown the same in a form found practically efficient, and in which Figure 1 is a perspective view of my improved cleaning device, and Fig. 2 is a side elevation, partly in section, of so much of a spoolingmachine as will serve to illustrate the application of my improved cleaning device thereto.

Referring to the drawings for a further description of the invention, A and A are two rectangular shaped longitudinal bars each having depending L-shaped arms a and a. In the upper portions of these arms are formed oblong slots a and a, for a purpose to be presently more particularly described. (last with or otherwise secured centrally to the longitudinal bars A and A are right-angular supporting-seats B and B, having two or more slots, 2) and 1), formed in the bottom thereof,through which broad-headed screws 0 and c are inserted for holding the bars with their knives (to be presently more particularly described) in proper position for the cleaning of the fibrous material in its passage between them,

as fully shown in Fig. l. The longitudinal bars A and A have formed integral therewith knives a and a, which are arranged in series at any angle to the horizontal and vertical planes of the bars, and the sides of which knives are beveled off or taper slightly from the longitudinal bars to the outer free extremities thereof, while the edges are either beveled off or square.

D and D are horizontal rods threaded for a portion of their length from both extremities, on which nuts d (l and d d" are secured for retaining said rods in position vertically in the respective slots a and a" of the depending arms a and a at each extremity of the longitudinal bars A and A. This arrangement of the rods D and D, forming guides for the yarn or other fibrous material in its passage between the two series of knives of the device, affords simple and effective means whereby it is rendered possible to utilize the entire cleaning-surfaces of the two series of knives before there will be any occasion to remove the same for sharpening and grinding.

Vhen, however, it is found necessary to remove the knives for sharpening and grinding, the operation may be readily conducted and the lower end extremities of the L-shaped depending arms a and a will be ground off uni formly with the knives, in order that when they are replaced the lower extremities ofthe L-shaped depending arms will serve to insure absolute certainty of position for the knives, which may be quickly set by hand by simply placing the device on the supportingbracket, (shown,for instanee,in Fig. 2,) and then bringing the respective L-shaped depending arms of the bars A and A snugly up against each other, which position, for certainty of action in the cleaning of the material ll] its passage between the knives of the device, will be found clearly illustrated in Fig. 1 of the drawings.

E is a slightly-curved bracket Lil-shaped at one extremity, having formed integral there with two rectangular-shaped seats, e,on which the right-angular supportingseats Band B, formed with the longitudinal bars A and A, are mounted and held to place thereon by means of screws 0, fitted through the slots b and b in the bottom of said seats 13 and B. The opposite extremity of the bracket E has formed therewith a hub, c, which is mounted on a horizontal bar, 6", and the bracket held to place thereon by means of atighteningscrew,

I desire it to'be distinctly understood that the L-shaped depending arms not only insure certainty of position of the knives for the cleaning operation, but also obviate tensional friction. Forexample,whilethesericsofknives are formed preferably integral with each of the rectangular-shaped longitudinal bars from an economical standpoint and for operation, so that a series of knives of one bar willoccupy aposition between a series of knives of the opposite bar, yet, nevertheless, they are not so arranged and supported on the bracket as to produce a friction between them and the material undergoing the cleaning operation, because if a tensional friction were produced, the material, from its very nature, would be instantly severed or cut and the device rendered incapable of performing the function and ends to be accomplished-that is to say, removing mote, fuzz, or small particles from yarn or fibrous materialin its passage between them. This I have fully demonstrated in the actual practice of the invention and have found that excellent results are produced by forming the L-shaped arms at each extremity of the longitudinal bars A and A, which insures a proper situation of the respective series of knives from each other.

WVith special reference now to Fig. 2,which" shows a sectional side elevation of so much of v a spoofing-machine as will serve to illustrate the manner of applying my improved cleaning device thereto, and in which I is a portion of one of the standards of the machines, J is the bobbinholder. J is a curved arm having hinged thereto a light depending wire guide, j, of any suitable construction and which supports the bobbin 7' and guides the yarn or other material from the bobbin and thereby regulating as well the tension of the same therefrom. The bobbinholder J and the wire guidej are suitably hinged to a rightangular bracket, J attached to a frame, j running along the front of the machine. it is a hook-bearing secured to the lower crossframe, i, of the machine, in which is mounted a shaft, 70, carrying a rocker-arm, k, which is actuated by a heart cam movement (not shown, but which is so well understood as to not require any further mention or illustration thereof.) One extremity of the rockerarm in" is pivoted to a vertical connecting-rod, l, having a slight oscillating movement, and this rod is pivoted at its upper extremity to a a collar, Z, secured to a vertical rod, m, moving freely up and down through the horizon tal arms of a bracket, a, suitably attached to the machine when motion has been communicated to the rocker arm it, in any well-understood manner.

The brackets n at the respective ends of the machine have formed therewith a horizcntal frame, 12 extending the width of the machine, and a frame, a, is preferably secured to each end of the standards. At suitable distances apart in these framesn and n are formed 0 bearings a, for the reception of the spindles O, and to each of these spindles is secured a grooved wheel, a actuated through abelt, a, passing around a frictional drum, P, suitably journaled in the standards of the machine. Motion is imparted to this drum P through a belt, P, passing around apulley secured to a main driving-shaft. p is a spool mounted on the upper extremity of the spindle 0. To the upper extremities of the vertical rods m is suitably secured a horizontal rod, 6, on which one or more of the hubs e" of the brackets E are fitted and held in position thereon by means of tightening-screws c. To the seats e of each bracket are mounted the right-angular supporting-seats B and B of the longitudinal bars A and A, each provided with a series of knives, a and a, and held to place thereon by means of the screws c.

To the horizontal rod 0 or to the bracket E, is attached ashort vertical rod, R, having a slotted upper extremity, through which the yarn or other material is guided in its passage from the bobbinj to the cleaning device and therefrom to the spool 12.

The vertical connecting-rod Z, actuated by the rocker-arm k imparts an up-and-down movement to the horizontal rod 0, and moving therewith the cleaning device and vertical guide R, thereby automatically laying up the thread or yarn evenly onto the spoolwhen revolved by means of the belt n,passing around the grooved pulley a of the spindle 0, when the frictional drum P has had motion imparted to it from any suitable source.

The manner of applying my improved cleaning device to a spoofing-machine of the type illustrated in the drawings having been hereinbefore described, I will now explain briefly the operation thereof. I :0

The yarn or other fibrous material to be cleaned is passed in an upward direction from the bobbin j, held in the holder J, around the lower portion of the wire guidej, thence over the adjustable guide D in one end of the depending arms aand a of the longitudinal bars A and A, and between the two series of knives of the cleaning device, thence over the guide D, and thence upward through the slotted guide R and onto the spool p, whereon it is evenly wound when the mechanism of the machine hereinbefore described has been actuated, and all fuzz or other fine particles readily and effectually removed during the operation.

Having thus described the nature and objects of my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a device consisting of two longitudinal bars each provided with a series of knives arranged at an angle thereto, and with supporting-seats and L-shaped depending arms at right angles to said bars, of a bracket, and means, as described, for scour ing each seat to said bracket, all arranged substantially as shown and described, and for the purposes set forth.
