MEANS FOR REMOVING FLUFF OR DUST FROM SPINNING-BRANT GUIDES.

Specification of Letters Patent.

Patented July 15, 1919.

Application filed November 18, 1918. Serial No. 262,960.

. T 0 all whom it may concern:

the spindles to guide the rovings passing from the drawing rolls to the spindles. These rovings being-of light, delicate character, deposit fluff or dust on the guides which accumulates and is liable to catch on the rovings and form enlargements thereon,

, of one good form which either will not pass through the guides and therefore cause the rovings to be broken, or will produce lumps on the yarn, impairing its quality.

A continuous current of airdirected to the guides will clear the fluff or dust therefrom, but a continuous current is liable to break the light, delicate rovings, and if broken from this or other causes, the continuous current of air will blow the loose ends of the rovings about, thereby rendering it difficult to pick up and reconnect the ends of the rovlngs, and frequently the loose ends are.

blown over to and unite with rovings passing to adjacent spindles.

The present invention utilizes an air current for removing the fluff and dust from the guides, but the current is applied intermittently in the form of gentle pufi's of air with a frequency suflicient to prevent objectionable accumulation of flufi or dust on the guides, but with intervals of substantial duration between the pufi's when there is no air current 011 the rovings, and therefore, no liability of breakingthe same, and if the rovings should be broken from other cause, the intervals afford the operator suiiicient opportunity to pick up and reconnect the loose ends of the rovings.

The character of the invention will be best understood from the following description of means for carrying the invention into practical effect, shown in the accompanying drawing, wherein Figure 1 isa conventional showing of an assembly of members typifying parts of a spinning machine and equipped with one form of means which may be employed to produce the intermittent puffs of air on the guides; and

Fig. 2 is a plan of the parts shownv in Fig. 1.

eferring to the drawing, 1 designates a spindle typifying one of the spindles of a spinning machine which may be operated by means well known in the art, and therefore, unnecessary to illustrate herein. 2 and 3 typify the usual drawing rolls of a spinning machine mounted on shafts 5 and 7 driven in the usual manner. The rovings 9 pass between the drawin rolls to the spindles 1, and are guided in t eir passage therebetween by guides, in the resent instance, in the form of slots nected by hinges 15 with an inclined plate 11 (Fig. 2) ma board 13 con- 17 mounted on and secured to the frame member 19.

The character of the rovings is such that Next will be described one good form of means for producing the intermittent pufis of air on the guides to remove the flufi' or dust therefrom. This means, in the present instance, comprises a bellows 23 having a plate 25 secured to the frame member 19 and a movable or may be of a length sufficient to produce the intermittent puffs of air on the guides for hinged plate 27 This bellows a'series of spindles of any number as desired,

i and the bellows may be provided with an air discharge mouth 29 desirably in the form of a slit extending along and adjacent to the upper surface of the frame member 19.

Any suitable means may be provided for operating the bellows. In the present instance, this means comprises an arm 31 secured to the hinged plate 27 adjacent the free edge thereof and adapted to be engaged at intervals by a roller 33 on an arm 35 fast on a shaft 37 journaled in hearings in the frame. This shaft may be provided with any appropriate driving means to continuously rotate the same. In the present instance, the shaft has a pulley 39 fast thereon connected by a belt 41 with a similarpulley 43 on a countershaft.

In operation, the roller 33 once in each r0- tation of the shaft 37 will engage 'the arm 31 and thereby rock the hinged plate 27 of the bellows upward to expand the latter and fill the same with air. After the roller has lifted the bellows arm as described, it will pass beyond said arm and thereupon the bellows will be gradually collapsed by the weight of the hinged plate 27. This will produce a gentle puff of air in the form of a stream passing from the mouth of the bellows and directed thence along the top of the guide member 19 and the inclined plate 17 to the board-13. In passing over the latter, it will blow the flufi or dust on the guide board adjacent the slots 11 and remove the same therefrom. While the bellows is collapsing, the roller 33 will slowlycumulate in substantial amount on the guides, merely a gentle current of air will suflice to remove the same therefrom, and

i the force of the current will not be sufficient to break rovings of normal character. If,

however, the rovings should be locally at tenuated or weakened to such an extent that the air current will break the same, or if the rovings become broken from other cause, the intervals between the puffs of air are suflicient to enable the operative to readily pick up and connect the ends of the rovings. The broken ends of the rovings will not be blown about and render it diflicult for the operator to pick up the same, and there will be no danger of blowing the loose ends of the rovings over to unite with adjacent rovings.

By the invention simple and effective means is provided for removing the flufl' or dust from the guides, and while this means,

in the present instance, is in the form of a bellows, it will be understood that other means may beemployed for producing the intermittent puffs of air as described.

Having described one good form of the invention without limiting the same thereto, what I claim as new and desire to secure by Letters Patent is 1. In a spinning machine, the combination of drawing rolls, a spindle, a guide for a roving between said rolls and spindle, and means to produce intermittent puffs of air to remove fluff or dust from said guide.

2. Ina spinning machine, the combination of drawing rolls, a spindle, means to guide a roving in its transit from the rolls to the spindle, a bellows to produce intermittent puffs of air to remove fluff or dust from said guide, and means automatically to operate said bellows.

3. Ina spinning machine, the combination of drawing rolls, a spindle, a guide for a roving between the drawing rolls and spindle, means to produce intermittent puffs of air, andmeans to direct the air to said guide to prevent accumulation of fluff or dust thereon such as might break the roving or impair the spun yarn.

4. In a spinning machine, the combination of drawing rolls, a spindle, a guide for a roving between said rolls and spindle, and means to produce intermittent pufl's of air on the guide to remove flufl or dust therefrom and comprising a bellows, a rotary member, and means actuated by said rotary member for operating said bellows.

5. In a spinning machine, the combination of a series of drawing rolls, a series of spindles, a series of guides for rovings between said rolls and spindles, and a bellows common to said guides for producing occasional pufis of air to remove flufi' or dust from said guides. K 6. In a machine of the character described, the combination of a guide for a roving, air receiving means having a mouth directed toward said guide, and means for automatically causing intermittent pufls of air to pass from said mouth to said guide to remove fluff or dust therefrom.

7. In a machine of the character described, the combination of a member having guide openings for rovings therein, air receiving means having a discharge mouth of suflicient length to deliver a current of air to said guide openings, and means for causing the air to pass from said mouth in the form of intermittent pufi's to remove fluff or dust from portions of said member adjacent said guide openings.

In testimony whereof I have signed my name to this specification.

WILLIAM E. WALSH.
