YORK,1ASSIGNOR To AMERICAN CARD FEEDING MECHANISM FOR CARDlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 686,071, dated November 5, 1901'.

Application filed September 13, 1900. Serial No. 29,868. (No model.)

To all whom it may concern:

Be it known that I, JAMES HOGG, of Amsterdam, in the county of Montgomery, in the State of New York, have invented. new and useful Improvements in Feeding Mechanism for Cardin g-Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description. 1

My invention relates to a feed mechanism for carding-machines of a new construction and mode of operation in which the stock-- such as wool, cotton, or other fiber-is drawn out of the receptacle by two combs arranged one on each side, by which the fiber is main tained in the best possible condition without being rolled up or sorted and delivered in light uniform locks continuously in the center between the combs, where it may be received by any suitable 1nechanism-such as toothed rolls, a toothed apron, or scalefor transfer to the cards, pickers, washers, driers, or other mechanism.

The essential featuresare a gravity feed chute or receptacle having openings in its bottom, in which openings move toothedextractors to draft or draw out the stock. The bottom of the receptacle maybe of any suitable construction. Preferably there are two series of parallel grooves or slots, one each side, communicating with a common central open ing at right angles to the slots. In such a construction there would be two series of extractors arranged on each side of the central opening and at equal distances therefrom. Each series of extractorsoperates in its corresponding series of slots, which may be formed by toothed cross-bars or bars of other suitable construction. One series of extractors would operate, (in one series of slots;) but two, as here arranged, are much better.

In the drawings herewith and in this specification the same reference charactersindicate the same parts in all the figures.

Figure I is a vertical cross-section of a feed mechanism, showing a desirable form of my invention. Fig. II is a top plan view with portions shown in section and portions broken away. Fig. III is an end elevation showing 50 the operating shafts, gears, &c. Fig. IV is a vertical section showing diagrammatically a eoinbinationof my invention with another form offdelivering mechanism. Fig. V is an enlarged plan of a toothed finger. Fig. VI shows in plan one end of a modified form of comb. Fig. VII shows in plan a portion of a modified form of grating. Fig. VIII shows a modified form of the comb, in which toothed disks are used as extractors instead of reciprocating fingers.

In the figures, lindicates the feed-box or gravity-chute towhich the mixed wool or other fibrous stock is delivered by any suitable means.

2 2 are the end plates supporting the box and other parts of the mechanism. The bottom of the box is composed of a grating of any desirable form. In the grooves between its 'cross-bars reciprocate the toothed fingers 3 3 of the feed-combs 4 e to draw out from the chute and deliver the wool uniformly in very light fine open locks to the receiving mechanism (without separating the different kinds ofstock) through the central opening A. The teeth of the fingers are hooked or inclined more or less toward the center to engage with the fiber. The bottom of the box may be made of curved bars 5 5, having teeth 6 6, pointing inwardly and downwardly to prevent'the pushing back of the wool by the combs. These bars are sustained on shafts 7 7 by set-screws 8 S,'permitting vertical adjustment of the bars, so that the teeth of the combs, extending above them more or less, bring down a greater or less amount of wool. Notc'hes 9 9 are formed in the end ofthe bars to engage with any wool that may remain in the fingers as they are returning and clear them.

The toothed fingers or extractors 3 3 are arranged in two opposite series on the rockshafts 10 and 11, by which they are reciprocated between the racks to engage with the Wool and deliver it substantially in the center. The comb and finger may be of any desirable form and provided with a greater or less number of teeth arranged in one or more series on each fin ger. The fingers are cheaply and easily cut from a sheet of metal and then secured to the shaft. The combs may be arranged to operate together, bringing down the wool from both sides simultaneously or ing of the resisting-roll.

alternately, as shown in Fig. I, which is better, delivering continuously by alternate combfuls instead of intermittingly, bot-h combfuls coming down together.

The combs or extractors may be of different forms and operated in different ways, the essential feature being the teeth extending up through the slots in the box-bottom and moved .to draft the stock. The elements which make up the comb may be of any suitable form, such as toothed fingers secured to a rock-shaft or otherwise reciprocated or rotating toothed disks performing the same function.

To describe the other parts of the mechanism shown in Fig. 1, arms 14 14 of the combs or fingers are pivotally connected by links 15 15 to the rocking guide-bars 16 16, whose supporting-arms 17 17 fit around the ends of the resisting-roll shafts 18 18, as shown in Fig. I. These rocking guide-bars form a second receptacle for the wool'and are rocked by their connection to the combs to press the W001 constantly but lightly toward the center, so that it is kept in a more compact and uniform condition, and a continuous supply is more uniformly delivered by the spiked feeding and resisting rolls 20-20 to the first spiked drafting-roll 22 on shaft 23, from which the wool is picked ofi by the faster-moving second spiked drafting-roll 24 on the shaft 25.

26 is a wiping-roll or stripper-roll operating at a speed between that of the feeding-rolls and of the faster drafting-roll to insure clean- A bur-guard 27 on shaft 28 may be arranged under the second drafting-roll for cleaning the wool and preventing the passage of foreign bodies.

Fig. IV is a diagrammatic representation of an adaptation of my invention, in whichthe combs and gravity feed-chute are arranged to deliver the stock without the feed ing or other spiked rolls directly to a scale,

- whence it is delivered by a continuous-apron to the card mechanism. The fingers of the combs are here indicated bya and b, respectively, so arranged and operated as to move alternately and. when reaching the lower position rest there momentarily till the other comb has come down, by which the stock is cleaned or stripped from the fingers of the first. In Fig. IV the comb a has moved down first and is timed to rest there momentarily till comb b has come down. Comb a is now about to return to dotted position for another supply of wool, during which time comb b will rest in the position as shown. In this figure, 30 indicates a receiving-platform arranged on scales connected by a tripper to stop the operation of the combs when the scales have received a sufficient weight of stock. This is then automatically delivered by the delivering-plate 31 to the apron 32, on which it is uniformly compressed by the presser-bar 33 and then carried to the carding mechanism. This arrangement is adapted to any situation where greater certainty is necessary in feeding to deliver a uniform quantity of stock in a given time.

The extractors and rolls are operated by any suitable mechanism, such as best shown in Figs. II and III.

38 is main shaft journaled in bottom of frame carrying beveled gear 39.

40 is vertical shaft journaled at 41 41 and carrying beveled gears 42, 43, and 44, the last meshing with gear 39. With gear 42 meshes gear 45, engaging with gears 46 46 to operate the combs through cranks 48 48, pitmen 49 49, and cranks 50 50 on shafts 1O 11. With gear 43 meshes gear 51 on shaft 52, carryin g pinion 53,meshingwith feeding-roll gear 54 at one end. At opposite end both feedingroll gears 54 54 on shafts 18 18 engage, thus operating feedingrolls. Gears 58 and 59 may be drawn'by chain 60 from pulley 61- and main shaft 38 from pinion on. the pulley through

gears

62 and 63. I

While my invention relates, broadly, to the combs with their'spring-fingers operating in the slots in the bottom of the chute, yet the forms of these parts may be varied, the fingers and rack-bars may each be cut or stamped from a single piece of metal, or, as shown in Fig. V, the finger may be made of the arm 0, with the toothed plated riveted to its end, or, as shown in Fig. VI, an arm e may be secured to shafts 10 and 11 at each end carrying a solid continuous bar f, to which is secured the toothed plates 01 d.

In Fig. VII is shown a variation in the form of the grating and bars, the bars being a part of the solid piece It, fitted to the shaft 7, in which slots jj are cut for the passage of the toothed fingers.

The guide-bars 16 16 are preferably operated as I have described, but maybe disconnected from the combs and maintained stationary about in the position of the left-hand rocking bar 16 in Fig. l.

In Fig. VIII is shown a construction in which the combs are made up of series of toothed rollers extending up between the bars. The roller-teeth are inclined in the same direction as on the toothed fingers and the rollers are rotated, as shown by the arrows, to draft the wool through the central opening.

The cotton, wool, &c. to be carded are generally blended of different qualities or of different lengths of fiber, the separating or sorting out of these various qualities in the feed is very objectionable, the blended stock must also be freed from foreign matter, and the knotty looks or other portions be opened before feeding in order not to injure the delicate card-clothing. Heretofore a spiked apron or roll has been used, which imparts a rolling motion to the stock and tends to sort it out, so that where the stock is composed of long and short fibers mixed the long resists the action of the comb or beater stripping off the surplus, while the short drops off and back into the supply, and the long stock is carried more readily to the card and the supply gets poorer and poorer the longer the intervals between the renewal of the supply. It is a well-known fact among carders and mill men that'the evils attending the common practice .of feeding from one side of the supply and combing and beating the surplus back has always made it impossible to preserve the blend which has been so carefully manipulated in the picker-room,

ment of receptacle and extractors the stock is brought down from the chute in small portions and in a very light open condition, so that it is supplied to the carding mechanism in the best possible condition and with great uniformity.
