CLEANING DEVICE FOR GILL-BOX FALLERS I Filed June 26, 1934 iatented June 18, 1935 Thisinvention relates to gill-boxes used in the preparation of wool for spinning. In the operation of such machines it isf'ound that dirt'and other waste material accumulates quite rapidly on the fallers andneedles, so that it is necessary 1 proved means by which the lower fallers and needles ina gill-box may be automatically cleaned as the machine continues to operate, so that lost time due to the cleaning of fallers is very largely eliminated.

My invention further relates to arrangements and combinations of parts which will'be hereinafter described and more particularly pointed out i in the appended claim.

A preferred form of the invention is shown in the drawing, in which Fig. 1 is a diagrammatic sectional side elevatioin of a gill-box having my invention embodied therein;

Fig. 2 is a plan view of certain parts, looking in the direction of the arrow 2 in Fig. 1;

Fig. 3 is an enlarged partial plan view of a cleaning brush;

Fig-4 is a sectional side elevation, taken along the line 44 in Fig. 3, and

Fig. 5 is a rear view, looking in the direction of the arrow 5 in Fig. 4.

Referring particularly to Figs. 1 and 2, I have shown portions of a gill-box of the intersecting type, in which upper and lower sets of fallers are used.

The gill-box comprises front or feed rolls III, a stationaryguide H, a series of upper fallers l2, a series of lower fallers [4, back or delivery rolls l5, and a guide or trumpet 16 through which the sliver S is delivered to press rolls l1 and a receiving can I8. An apron or conveyor l9 runs over the lower back or'delivery roll l5.

The fallers l2 and M are progressively advanced toward the delivery rolls l5. bygill- screws 20 and 2| (Fig. 2). After completing their travel toward the delivery rolls IS, the upper fallers are raised and the lower fallers are lowered to secondary gill screws (not shown) which are of steeper pitch and return the fallers toward the feed rolls ID as indicated by the arrow (1 in Fig; 1.

After completing their return travel, the upper fallers are lowered and. the lower fallers are raised :PATE I iCE. I parameter-1 9x Harry Whitaker. Scuth'fBarre'," Mass Application ,itiiiefzs, lN'c. H v

om er i l t eaad nr r hems lv si rm n art Of my Pr ent .i ven o =.w.h h r lates P rtia l- I U forcleaning. tha werler 1. nd. th needl s t re ,d r et n eturn moveme t-. 2 ni ia ina sifi larly to .the: provision of. improved ,means For this p r os el ril vi a br hl pret rably formed of a plurality of tuft s 25 of stiff bristles or wire mounted in a rigid back or cross bar 26 preferably having enlarged end portions 21. The bar 26 may be of wood, aluminum or any other suitable material.

The ends 21 of the bar 26 are secured by screws 28 to angle brackets 30 having elongated slots 3| (Fig. 4). Bolts 32 extend through the slots 3| andsecure the brackets to the side frames 33 of the gill-box. I

I position the brush B so that it will engage the fallers I after they have completed their forward return movement and while they are being lifted to replace them in initial working position as indiplaced the bristles upwardly, at the same time wiping the dirt and other waste material from said faller l4 and its needles N. r As the faller continues its upward movement, the bristles 25 willwipe downward along the side of the faller to its bottom edge and will then'snap back into normal position, forcibly discharging the dirt and waste material downward to the floor or to a suitable receptacle.

' The faller [4 thus cleaned continues its upward movement to initial working position at the feeding end of the machine and resumes its travel toward the delivery end of the machine.

Important advantages arise from locating the brush B at the particular point in the machine shown in the drawing. As above described, the

brush l3 atthis point operates on an upwardly moving faller, and the dirt and waste material is thrown downward away from the path of movemeat of the Iallers or of the sliver S entering or passing through the machine.

Furthermore, ample room is available at this point for mounting the brush without disturbing the normal setting of any other part of the machine. This position of the brush also permits the iallers to continue their travel to points very closely adjacent to the back or delivery rolls I5. I thus avoid the serious disadvantage of increasing the [pace between the fallers and the delivery rolls, and I permltthe machine to operate on material of very short staple.

In actual operation, my invention has been found entirely satisfactory and efiective for the purposes indicated and has been found to keep the lower Iallers and needles entlrelvckar of: dirt and waste material during long continued operation, thus avoiding the'lost time previously occasioned by frequent cleaning of the. loweriall Y ers. I have not applied my invention to the cleaning of the upper fallers, as dirtthus removed would (all "on the sliver and would be seriously objectionable. Furthermore, dirt and waste materlal accumulates very'slowly on the upper fall- -ers and these tellers are substantially less numerous than the lower tellers. They are also readily accessible, so that occasional cleaning of the upper fallers may be accomplished quickly and easily and with's'light loss of time.

While I have shown my invention applied to an intersecting gill-box having upper and lower fallers, it will be understood that the invention is equally applicable to the type of gill-box in which the upper fallers l2 are omitted and a single set of lower fallers only is used.

While I have shown a fixed bristle brush in the drawing, the particular type of brush may be varied and the brush may be eitherfiggedor rotary, provided theworking position of thelbrusli at the feeding end of the machine is inainta'ined.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claim, but what I claim is:-

A gill-box having, in combination, a plurality of fallers having faller pins and successively movable fronran initial working position along a substantially rectangular closed path having an uping successively and directly engaged by said;

fallers closely adjacent'said pins as said fallers are moving upward to initial workingposition at the feeding end of the machine.
