11 Claims. (o1.15-20)' The invention has relation to lint clearing devices for use in removing lint and fly from spinning frames and other textile machinery.

In spinning frames, roving frames, twisters, and various other textile machines operating upon traveling yarns, the removal of lint and fly which rapidly accumulates on parts of the machine adjacent the running yarns is necessary periodically in order to prevent accumulated masses of fibers becoming caught by the traveling yarns and carried forward thereby to become fixed in the yarns during the process being performed on the latter, and resulting in the formation of slubs and bunches in the finished yarns which seriously impair their-value.

The principal object of the present invention is to provide a novel and improved portable device adapted to blow lint and fly from the ring-rails and creels and parts adjacent to these localities upon spinning frames, roving frames, and similar machines.

Special objects of the invention include the provision of means for cleaning two spinning frames at once by the improved device, and for adapting the device to spinning frames of different proportions. 1

Further objects of the invention will become apparent from the following description.

The invention consists in the novel and imtions of parts shown and described in the accompanying drawings and specification and particularly pointed out in the claims appended hereto.

An illustrative embodiment of a preferred form of the invention is shown in the accompanying drawings, in which,-

Fig. 1 is a side elevation.

Fig. 2 is a front elevation.

Fig. 3 is a plan view.

Figs. 4 and 5 show in front and side elevation, respectively, the means for extending the delivery flues acting in connection with the ringrails.

Figs. 6 and 7 show in side and front elevation, respectively, the means for extending the creelclearing fiues.

Having reference to the drawings:-

The device of the invention consists in the main of a wheeled carriage adapted to pass .down the aisle between two spinning frames located as is usual in spaced opposed relation, bearing a fan, blower, or other means for producing a blast of air, and fiues or conduits for delivering proved features of construction and combinak by e b ow of one or both of such opposed spinning frames, which it is desired to clean and clear of lint or fly. This carriage is or may be of any suitable or desired form, that herein shown comprising a box-like body 1 provided at midlength with a pair of large wheels 2 rotatably mounted upon a shaft 3 fixed in connection with the body so that the wheels may be rotated in opposite directions to facilitate sharp turning of the device when wheeled about. Additional small wheels or casters 4 are provided at the ends of the body 1, preferably arranged so that they will be clear of the floor when the device is balanced upon the large wheels 2. The body is provided with a hand-rail whereby it may be propelled manually past the spinning frame or frames, or other machines which it is desired to clear and clean by means of the blast issuing from the device.

Suitable means for producing a blast of air is mounted upon or within the body 1, and in the present embodiment comprises an electric motor '6 driving a fan '7 of-familiar propeller type, mounted on a bracket 8 within the fan chamber 9 depending from the top surface of the body 1 and enclosed and protected by screening 10 applied to the front and both sides of the body 1, the screen serving to admit a free flow of air to take the place of that expelled Other types of blowers such as the centrifugal type may of course be employed to produce the blast of-air.

An air passage of generous dimensions is provided in the top of the body 1 above the fan Land'a chamber 11 of cylindrical shape is applied to a rim 12 on the body 1 about the said air passage, resting on the top of the body 1 and fitting with sufficient freedom about such flange 12 to permit the chamber 11 to be rotated about its vertical axis as will be described hereinafter.

The; chamber 11, of hollow cylindrical form, has affixed in its sides in diametrically opposed relationthe discharge iiues 13 which receive at their open lower ends 14 a portion of the blast ofair driven upward within the chamber 11 by the fan '7, and which deliver such portion of the blast horizontally from the chamber 11 in opposite directions at the proper height to blow lint and fly from the ringrails, and other parts of a spinning frame in the locality of the ringrails, as the device is wheeled down the aisle between oppositely-located spinning frames. In order to deliver a blast havingconsiderable vertical extent, and of substantial uniformity throughout such vertical extent, the flues 13 are provided with a plurality of vanes 15 properly shaped and located to distribute the blast with equal intensity through the vertically elongated discharge ends 16 of the fiues. This provision makes it possible to clean the traverse rail and the parts above and below the same regardless of their relative elevation at the moment when the cleaning device passes along the front of the spinning frame.

The top of the chamber 11 is provided with a head 17 having a rectangular aperture provided with a collar 18, within which latter fits slidably in the rectangular lower portion 19 in connection with the fiues 20 which direct portions of the blast horizontally in opposite directions to blow the lint and fly from the creels, creelsupports, and other portions of the spinning frames in the locality of the creels which commonly surmount the spinning frames. As in the case of the fiues 13 for clearing the vicinity of the ring-rails and other associated parts, the blast delivered laterally from each fiue is contrived to have considerable vertical extent, and theflues are provided with vanes 21 similar in construction and arrangement to the aforesaid vanes 15 which are designed and installed to distribute the intensity of the blast uniformly throughout the vertical extent of the discharge ends 22 of the flues 20.

Preferably, the vanes 15, 21, will be made of sheet metal extending across the full width of the rectangular flues 13, 20, and preferably, also, the position of their extremities 23 nearest the fan will be adjusted into positions giving the most uniform dispersion of the force of the blast over the entire discharge end of their respective fiues, and then fixedly secured in such adjusted position; though it is within the scope of the present invention to provide means for positioning these extremities with capacity for further adjustment in case need therefor should arise.

Adjustment of the relative height of the dis,- charge ends 22 of the creel-clearing fiues 20 with respect to the ring-rail clearing'flues 16 is .provided for by arranging the portion 19 to telescope freely within the chamber 11 as stated, and means for retaining the parts in adjusted position are provided in the form of rods 24,

having their upper ends fixed in brackets 25 bolted to opposite sides of the member 19, and sliding through guides 26 in connection with the collar 18 on the top of chamber 11. When the proper elevation of the creel-clearing flue unit has been determined, the adjustment ismain- .tained by tightening clamping screws 27 to secure the rods 24 fixedly within their guides 26.

To provide for delivering the clearing blast into proper proximity to the traverse-rails and the creels to be effective in clearing these portions of the machine, while providing for the variations within certain limits in the spacing of spinning frames adopted by various mills, extensions 28 and 29 are provided to be attached respectively to the delivery ends 16 of the traverse-rail clearing fiues and the delivery ends 22 of the creel-clearing flues. The device of the invention is designed to be narrow enough to pass through the narrowest aisles between oppositely-located spinning frames, as installed in a mill, and it is intended and preferred that the device shall be fitted to. the spacing adopted in any one mill by the use of extensions 28 and 29 of an appropriate length such that when applied to the delivery ends 16 and 22, they will discharge their proper portion of the blast in close proximity to the parts intended to be cleared thereby and on each of a pair of oppositely-looated spinning frames as the device is wheeled down the middle of the aisle between two rows of spinning frames. The extensions 28 are applied to the delivery ends 16 of the traverse-rail clearing flues by means of ears 34 passing over studs 35 protruding from the sides of the chamber 11 and are retained thereon by nuts supplied to said studs. They are equipped with vanes 36 constituting continuations of the vanes 15 within the flues 13. The extensions 29 for the creel-clearing flues 20 are without vanes, as they are designed to telescope over the exterior of the flues 20 to enable their lateral extent to be adjusted to a relation giving most effective results.

To provide for reduction of the overall width of the device when necessary to pass the same through narrow openings, as for instance between the belts connecting an oppositely-located pair of spinning frames with the overhead drive shaft, the chamber 11 is mounted on the body 1 with capacity for limited rotation about a vertical axis, as referred to hereinbefore. This permits the operator to swing the whole of the structure above the body 1 through an arc of 90, in order that the delivery ends of the flues with their extensions may be brought into line with the direction of movement of the carriage as permitted by the wheels thereunder. By this means the flues will be brought within the width of the carriage, as indicated in dotted lines in Fig. 3, and being themselves relatively narrow can be passed easily through any passage capable of permitting transit of the body 1. For rotating the chamber and the flues borne thereon in this manner, a handle 30 is provided on the side of the chamber 11, which engages stops 31 fixed on the top of the body 1 to limit its move ment in either direction.

The motor 6'for driving the fan 7 or other blower may be provided with electric current from any suitable source, as by means of a fiexa ible cable. In the event that it is preferred to make the device a whole self-contained unit, and increase its mobility by dispensing with a cable attached to a power line, it is contemplated to drive the motor 6 by means of storagebatteries carried within a compartment 32 of the body 1, such compartment being shown as provided with a hinged cover 33 for the purpose of facilitating access thereto.

In certain instances it may be desirable or necessary to regulate the relative force of the blast directed in the vicinity of the traverse rail, with respect to the force of the-blast delivered on to the creels. Such occasion may arise where fine ends are being spun, and the use of a heavy blast upon the traverse rail tends to deflect and break the yarns. To provide for such adjustment of the force of the blast, dampers 37 are provided in the delivery ends 16 of the fiues 13 controlled by an arm 38 fixed upon the common maintain the dampers in adjusted position. A 3

similar arrangement of dampers 42 is or may be provided within the fiues 20 which deliver a clearing blast to the creel-portions of the spinning frame, so that if desired delivery of air laterally from the device in one direction may be 1 suspended to concentrate the blast on a single spinning frame.
