CoILER-FRoNT For. CARDS.

Specification of Letters Patent.

Patented July 4, 1916.

To all whom it may concern:

Be it known that I, EDWIN A. ROONEY, a citizen of the United States, residing at Fairhaven, in the county of Bristol and State of Massachusetts, have invented the following described Improvements in Coiler-Fronts for Cards.

The invention is an improvement in coiler front apparatus for divided cards, whereby each of the many subdivisions of the card fleece can be uniformly and practicably condensed and coiled in individual sliver cans from which cans they can be run directly into a Slubber or coarse roving frame without intermediate doubling or drawing.

WVhile the invention and particularly certain features thereof can be used with divided cards producing only four divisions of its fleece, it is more particularly adapted for use with cards producing eight or more divisions or fleece sections.

In certain respects the invention is an improvement on the structure disclosed in application Serial N0.'740,971, filed January 9th, 1913, by Elwin H. Rooney, the object being to simplify and enhance the convenience of use of said structure through a certain method of groupingor arranging the sliver cans and the distributing and coiler mechanism, as hereinafter set forth, so that the operator may more conveniently reach the said cans as well as the doffer and delivery mechanism of the card without disturbing the uniformity of treatment which each sliver must receive.

In the accompanying drawings, Figure 1 is a top plan view of a portion of a divided card with one form of the invention applied thereto. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is a top plan of a modified arrangement. Fig. 4 a side elevation of Fig. 3. Fig. 5 is a top plan, with parts in section, of the can stands for the form of Figs. 1 and 2. Fig. 6 is a similar view of the can stands of the form shown in Figs. 3 and 4. Fig. 7 is a section through the table surface and calender rolls of either form.

The doffer cylinder marked 1, may be regarded as the dofi'er of any suitable card adapted to produce a fleece in the form of numerous narrow strips or' ribbons,herein termed fleece sections. For this purpose the cylinder in the present case is divided by a series of tapes 2, which divide the fleece formed thereon into a plurality of fleece sections, eight in number in the machine illustrated. These fleece Sections are removedv from the cylinder by an oscillating dofl'er comb 3, which, as observed in the drawings, operates at the front side of the cylinder so that any dirt it liberates may fall to the floor and not on the cylinder. As the present lnvention is largely concerned with the economical working of cotton Waste containng more or less dirt, the advantage of locating the doffer comb at this point is obvious. From the doffer comb each fleece section passes immediately into one of the trumpets 4, which are mounted in a cross-plate 5, eX- tending across the card directly in front of the comb. The cross-plate and its trumpets are set substantially at the same level as the doffer comb, so that the fleece sections are sub ect to the least possible attenuation in moving to the trumpets. A set of rolls operates directly in front of the trumpet nozzles drawing the condensed fleece sections therethrough and delivering them from the card. In the present case these rolls are made up of a single bottom roll 7 (dotted lines Fig. 2) which is driven by a gear train 8 from the dofler wheel 9 of the card, and a set of top rolls 10 resting by gravity upon the bottom roll and held in place thereon by means of the crotch supports 11. All the top rolls 10 are of the same weight and each serves two adjacent fleece sections, pressing equally upon each of them. A Weighted clearer 6, (Figs. 1 and 2) of any suitable form is placed on the top rolls 10. This clearer is omitted from three of the rolls as shown in Figs. 1 and 3. The rolls and their trumpets cooperate to condense the very tenuous and narrow fleece sections discharged by the dofl'er comb so as to enable them to be elevated safely to the level of the entrances to the cans into which they are to be coiled. The gear train 8 on the card also drives a cross shaft 12, suitably supported in brackets 12 on the overhanging ends of the card frame, and whichserves as the driving member for the parts of the coiler front mechanism, driving the section-com veying mechanism of the latter through the two inclined shafts 13 and the coiler apparatus through the two upright shafts 14, both of which are bevel geared to said cross shaft 12 near its center.

The coiler front mechanism according to this invention is divided into two or more sections which maybe symmetrical duplision consists of adistributing mechanism or table structure set on legs resting on the floor or otherwise supported in front of the card so as to accommodate a group of onehalf or one-third, or a portion, of the number of sliver cans, beneath it. Said structure is elevated above the level of the doffer and delivery means of the card so as to accommodate cans of large capacity and standard diameter and each is also equipped witha -seriesof pairs of calender rolls or other means for-elevating the fleece sections,

from the level of the condensing mechanism,

to the level of the cans and conveying and depositing them in the latter, as well as with meansfor coiling the sections in the cans.

The calender rolls are driven by one'of the shafts 13 and the coiler mechanism by one of the shafts 14. WVhen the distributing mechanism is divided into two divisions, as in the case illustrated, they are disposed in front of the sides of the card so as to leave an intermediate central space between them, in which the attendant may approach the card to attend to the piecing of the middle fieecesections or for other purposes' If three or more divisions are formed, similar spaces are left between them, such spaces being either for access to the card or for removal of the cans.

Inthe form of Figs. 1- and 2, the table structure constituting each division of the distributing mechanism is, of greatestdimensio-n fore and aft of the card and of least dimension crosswise of the card and is also somewhat wider near the card than at the opposite end, so as thus to accommodate the convergence of the fleece sections, as indi cated in the drawings, with the least obtrusion into the space left for the operator. The top surface of the table structure is de sirably smooth and at its end nearest the card turns downwardly forming the apron 16 inclined toward the card delivery. The sections are drawn upwardly over this apron and along or over the upper surface of the table, by means of the condensing'rolls 17 and 18, which also draw the sections through the trumpets 20 in the covers 19, thereby imparting a second condensation to each section. The lower rolls 17 are carried in or "below openings in the table structure, on'

shafts 21 driven by bevel gear connections with a shaft 22, which latter gears with one of the inclined shafts 13 above referred to, being thereby driven in unison with the card. The cover 19 bearing the trumpet 20 is hinged to the table structure so that it can be turnedupwardly when desired to uncover the roll opening, and the upper roll 18 is held in place on the lower roll by means of supports 18 which are covered by total which the cans rest orinany other suitable way by which the sections will be boiled in the cans so as to prevent snarling when removed.

vFig. 5 shows a can stand for the form of Figs. 1 and 2, 23 being .an inclosing casing which can be secured to the floor between the legs of the table structure, and 24 being the individual can stands, each secured to a gear 25, the set of these gears being intergeared by idlers 26 and driven by a gear train 27 from the upright shaft 14 above referred to, the lower end of which is stepped within said casing. As thus arranged the can stands 24 are driven by the card at a uniform rate of speed-and each can rotates eccentrically to the calender rolls 17 and 18. The distributing mechanism of this form is shown as accommodating four cans arranged in a single row extending away from, and parallel with the card. Additional cans may be added to the row as desired, the manner of grouping remaining the same.

Referring to Figs. 3'ancl 4, the card structure will be understood to be the same as that of Fig. 1, being designated by the same reference characters. The sections oflthe distributer and coiler mechanism each comprise a table structure 28 mounted on legs as in the preceding case but adapted to accommodate a double, instead of a single row of sliver cans thereunder. The upper surface of this table structure is also provided with an inclined apron 29, like the apron 16, of the form first described and is also slightly wider near the card than at its opposite end to accommodate the convergence of the fleece sections. The calender rolls 17 and 18 with their covers 19 and trumpets 20 are the same as the corresponding parts in the other form, but are arranged two abreast, so that every other fleece section may move to the calender rolls nearest the card and the alternate sections to the rolls farthest from the card. The driven rolls of each pair of rolls aremounted on a common shaft 30 beneath the table'which is driven by the card through an inclined shaft 13. The sliver cans are set on rotary stands 31, the same as thest'ands24, but arranged in a double row, extendingaway from the sides of the card and inclosed in a similar casing can stands permits access to the card in the same manner as in the case of the form first described.

It will be observed that whether the cans are grouped in single or double rows, the space between groups will be sufficient not only to admit the attendant but also wide enough to permit him to remove or inspect any one of the cans without touching or disturbing the others.
