useful Improvements in Cleaners for Spinning-Machines, of which the following is a specification.

This invention relates to cleaners forspinning machines of the kind shown in my U. S. Patent No. 1,129,312 of February 23, 1915, and the object of my present invention is to improve certain hereinafter described parts of said cleaner and its actuating mechanism.

The cleaner shown in my said patent comprises endless cords, traveling in one direction only and carrying wipers'which traverse the thread-boards, roller-beams, backboards and creels of the spinning frame and detach lint and other foreign matter therefrom. Each cord is guided by suitable pulleys and is weighted with a uniform tension to keep it straight and to cause it to. move with uniformity in one direction in a fixed path. The wipers or brushes remove the lint, etc.,' from the spinnino frame', which lint adheres not only to t he wipers and brushes but also to the cords and in order to clear the wipers and cords 'fromlint, etc., 1

adhering thereto brushes are provided which engage the cords and wipers anddetach the lint, etc., therefrom.

In my patented cleaner the cords extend over one end of the frame and the weights are applied to vertical portions of the cords and the cords are driven by pulleys mounted on a shaft actuated from the main shaft of the machine whichpulleys are arranged below the plane of the thread-boards, rollerbeams and back boards, and loops are formed in the cords which extend downwardly around the driving pulleys and also across guide pulleys. Y

I have found that where a large number of pulleys are employed to guide and drive the cords considerable -wear is produced which lessens the life of the cords and according to my present invention I provide means whereby the number of guide-pulleys may be reduced and-the driving mechanism much simplified. I have also so organized the cleaner that the cords may beshifted to one side when the thread-boards are raised during dofiing or at other times. In order to prevent the cord-weights ortension devices from swinging or moving out of proper operative position I have provided guides for the weights which, while permitting them to move vertically, hold them against any swinging movement and I have provided meansfor holding the cords and their wipers in close contact with the brushes so that lint, etc., may be effectually removed.

As stated in my patent above mentioned the cleaning cord is preferably made of cotton and preferably the cord consists of two strands of cotton twisted together. The wipers are preferably made of pieces of cloth such as flannel and I' have found that where metallic fastenings are used to attach the wipers to the cord the thread-boards, etc., are considerably worn by such metallic fastenings. In order to overcome this I attach the wipers to the cords by untwisting the strands .sufliciently to permit the wipers to be passed between them and then again twisting the strands to tightly hold the wipers. This I' find to be a secure way of attaching the wipers to the cords and no other fastening device is necessary, although preferably the-leading edge of the wiper is attached to the cord by a single stitch.

Other features of 'my invention will be hereinafter described.

lVhile my improv'eiiients are especially in tended for use in spinning machines, they may of course be applied to other similar cate the thread-boards, B the roller-beams, B theback-boards and O the creel. The

Fig. 3.

Each of the thread-boards is provided G. which extends-around a pulley g atone end of the'frame which spreads the, cord into two parallel members, and at the other end of the frame the cord extends over pul- 'leys g and from thence downwardly across the end. oftheframe where the loop formed thereby supports a weightedpulley H. As

usual, each thread-board l3 is'hinged to a roller beam B as indicated at b, and while the pulley g normally overlaps the thread- .board provision is made, as will-be hereinafter described, for movingthe pulley later- ;ally away from the threadboard so that the latter maybe lifted during dofling and at other times; The cord G carrieswipers or cleaners m which are held. close to the thread-board by the cord and operate to clean this board as well as the roller beam and back board.

Each of the thread-boardsand its associated roller beam andback-board is provided with a cleaner, as indicated in Fig.1, and the creel C' is provided with a similar cleaner. The cord I for the creel passes around a pulley I at one end of the, frame and over pulleys i at thejopposite. end of the frame. These guide pulleys are arranged to properly. spread the cord-and from thepulleys i the loop of the cord extends downwardly over a weighted pulleyJ. I, I

Experience has demonstrated that the often swing laterally to such an extent as .tointerfere with the efficient operation of the cleaner and to overcome this I have prothe axle thereof. Each leg of the bifurcated weight is formed with 'a vertical. slot 71. which receives a bearing blockh? in which the axle 72, of the pulley rests. Each weighted pulley ent r 1g idQ 0 able way. v

In-.orderto hold the. wipers in closecon- -;ta'ct with the brushesI provide the guards M which may be attached to the frame. in any suitableway close tothe brushes M.

which may be boltedto the faetory floor, or

may be supported by a frame H (Fig. 1)

bolted *to the" end frame of the machine.

Each guidebox is provided with a stop H which limits the upward movement of the 'weight. The guide boxes may be, made in various ways but are preferably so constructed that the pulleys extend throu h vertical slots 71. in the opposite sides of tie box. I

.I do-not. limit myselfto the particular formof weight guides shown as the same result may be accomplished-by other means.

Rotary brushes M, M, are. mountedto rotate on one of the end frames andto engage the vertical portions of the cords G and I. These brushes may be driveniin any suitable way,.preferably by means of belt .gearing N driven froma pulleyfn on ashaft 7 O which-shaft may be vdriven in anysu'it- ",AS shown in Fig. 2 the wipers are attached to the cord without the use-of mtallicfastenlngs. The cord employed preferably consists of two strands, and in order to attach a wiper the strands are untwisted sulficiently to allow the wiper to bepassed through between. the strands. then'the strands are again twisted, asshown in Fig. 2, and this serves .to securely attach the wiper to the cord.

For additional security however I mayattachithe'front or leading end of the-wiper to the cord by a single. threadolj' stitch X asshown inorderto prevent theleading end of-the wiper frompilingup or slipping back and. tl1us' forming a lump or knot which would ;.prev.ent: a proper drawing contact iw th' e v s pu ey.- I

I ac.- .COl'IlPllSll this by passing the pivotK oftlie .pulley 9 through a slotin therollenbeam and through the armlc of a bracket K which is connected .by a threaded stud k 'to an adjustable. vertically arrangedbracket- K at tachedto oneofthe end pieces A ofthe ma chine frame.

0, 0 0 0*, 0", 0 to theshaft- P which is the driving shaft of the machine and on which is mounted the band cylinder P" extending along the whole length of the frame by which the spindles F (Fig. 3) on both sides of the frame are driven through the bands 79. The shaft L on the opposite side of the machine is in like manner driven by a sprocket chain Q through the gearing shown which is of usual construction and need not be described in detail further than to Say. that the shaft 9 is the front fluted steel drawing roll which -drives the back and top rolls on that side of the machine. where it is located. The construction is such that the pulleys g are rotated at the properspeed to drive the cleaning cords, when the thread-boards are lowered or when the machine is in operation. When it is desired to raise the thread-boards the brackets K may be turned in the manner indicated in Fig. 5 so that the pulleys and cords are out of the way of the thread: boards. In practice, however, each cord and pulley will automatically swing into or assume the position shown in Fig. 5 as the lower or outer edge of the pulley comes in contact with the thread-board while the latter is being raised. WVhen the thread-board is released. or lowered the cord and pulley will be automatically brought back to working positions by reason of the fact that the cord is held at all times under tension by its weight. In order to support the inner ends of the brackets K at the desired elevation I provide lifting devices R each comprising a stem 1" which is threaded and carries nuts T which may be adjusted to hold the bracket K and consequently the pulley g in the desired plane.

The pulley I which guides and drives the cleaning cord I for the creel is secured to a vertical shaft .9 mounted to turn in a bracket S adjustably secured to the end frame piece A. The lower end of the shaft carries a beveled pinion s meshing with a corresponding pinion s on a horizontal shaft S mounted to turn in bearings in the bracket S and carrying outside the frame piece A a sprocket wheel T connected by a. chain t with a sprocket wheel 25 on a stud U carrying a. spur or intermediate gear V meshing with the wheels Q and 0'. In this way the pulley and the cord I are driven from one of the intermediate gears of the train of gears in the front drawing roll drive.

By my present improvements the devices for cleaning the cords and wipers is made;

more eflicient inasmuch as the cords. and

wipers. are held close to the brushes and the weighted pulleys are prevented from swingng away from the brushes. The threadboards can be very easily raised during;

dotting and at other times, it being only necessary to move the pulleys g sidewise and inward to a small extent so that they with the outer sides of the cords are moved out of the way of the thread-boards. Further-i more, the pulley g and the cord G are so arranged that they may be moved sidewise and inward automatically in the manner before described. These pulleys g constituteguides for the cords and also drivers therefor and;

receive motion from the usual mechanism employed for driving the drawing rolls. By comparing my present improvements with the mechanism shown in mybefore mentioned patent it will'be seen thatthe driving,
