SPECIFICATION forming part of Letters Patent No. 295,243, dated March 18, 1884.

Application led May 3, 1883.

'feeding apparatus for cardiug-machines in which the wool or other brous material is raised from a bin by an endless lifting-apron provided with teeth, which catch hold of the wool or material brought in contact with them, and carry upward what adheres to or is caught by them. Vihen the wool or material reaches the upper part of the bin, the loose hanging locks are struck back or detached by a rotary cylinder or comb, and what is retained by the teeth of the apron is carried over and delivered by suitable mechanism to the carding-machine. Sometimes, in addition to the lifting-apron, an endless apron is arranged. to

travel in a nearly horizont-al direction in the bottom of the bin, so as to carry the wool or material toward and against thelifting-apron, but the horizontal Aapron has no teeth.` The teeth on the lifting-apron are commonly secured from one and ahali' to three inches apart, or thereahout, `in slats which are'themselves fixed across theapron from one to two inches apart, and when k thus arranged the teeth carry up the long locks or stock most readily, while the shorter stock is apt to drop oit'and back into the bin. Therefore when course and ne. or long and short stock are mixed together in the bin for a blend for cards, the coarser or larger stock will be car ried upward and delivered to the cardingmachine in greater quantity than the tner or shorter stock, and effects a selection of stock which prevents theblend desired. If-there be added to the blend more short stock than is wanted for the purpose of causing the apron to take up the desired amount, no dependence can be placed upon the proportions, the blend is useless, and the value of' the self-feeder is destroyed.

tion is to remedythis defect.

The invention consists in the combination, 'with a bin for stock, ot' alifting-apron provided with rows of teeth, and receptacles or An important object of my invert-- (No model.) A.

buckets interposed between the teeth, and

mechanism for operating said apron and for delivering the material raised by said apron to a carding-engine or other machine.

The invention also consists in the combination, with a bin for stock, of an endless lifting-apron provided with buckets or receptacles for raising the stock, a beater or other strippingdevice near the upper end of the apron, for knocking large locks or bunches of material back into the box, mechanism for operating said beater or stripping device, and mechanism whereby the material raised by the lifting-apron may be delivered to a carding-engiue or analogous machine.

The invention also consists in a combination similar to that above recited, but including a lifting-apron comprising rows of teeth arranged in the ordinary way, and buckets or receptacles interposed between the rows of teeth. The buckets maybe composed of teeth closely arranged, or of sheet metal or other rmaterial provided with serrated upper edges,

which form teeth for catching and carrying up the larger stock, while the shorter stock is carried up by or in the buckets or receptacles.

In the accompanying drawings, Figure 1 is a vertical section of a feeder or feeding apparatus embodying my invention. Fig. 2 is a front view of the apparatus with t-he bin broken away, and Fig. 3 is a perspective view of a portion of the lifting-apron.

Similar letters of reference designate corresponding parts in the several gures.

A designates the bin for woolor other stock, and B designates an endless apron, which is employed for elevating the stock from the bin.

The bin may be of any suitable shape; but preferably its front side slants inward toward `the lower end of the. apron B, and 'comprises doors A', which may be opened to afford access to the interior mechanism and for iilling the bin. TvVhcn of the shape shown the stock will be caused to gravitate toward the apron lower part of the bin for moving the stock toward the apron B is therefore unnecessary.

The apron B may be arranged in any suitable position; but, as here shown, it` is arranged in an inclined position, and is supported by lowerand upper rollers, ce. The

IOO

bearings b of thev lower roller, a, are adjustable, and by means of bolts b may be drawn down to applytension "to the apron and cause it to work properly. l As here shown, the belt is provided with rows of teeth c and buckets or receptacles d, placed intermediately between said rows yof teeth. The teeth c may be inserted in slats secured to the apron as the teeth of liftingio aprons for card-feeders are ordinarily secured. The buckets or receptacles d may be made of teeth secured very near together, so as to form such buckets or receptacles; or they 'may be made of sheet metal stamped or pressed into the proper shape by means of dies, and secured to the apron B by rivets or otherwise. A portion of the apron and its buckets or 'receptacles are shown in Fig. 3, 'from which their construction may be more clearly understood. 2o If desired, the edges of the buckets or receptacles may be serrated to y'form teeth d. (Shown in Fig. 3.) C designates a beater arranged near the top of the apron B, and in such close proximity 2 5 thereto as to just clear the teeth 'c and buckets or receptaclesd in rotating. This beater may be of any suitable construction. As here shown, it consists of a wood or metal roll, e, having lags or strips e secured upon its surface, and wings or blades e2, of sole-leather, which are securely pinched orclampe'd between the lags or strips e. the lifting-apron, carry'up the long locks of wool, while the shorter stock is carried up by the buckets or receptacles, and 'the beater C is revolved in the dire'ction'of the arrow 'at whatever lspeed may be necessary to carry back the --overhan'ging locks of wool, but notlfast enough to drag the wool out of the buckets 4o or receptacles. i

I do not limit myself to the alternate 'arrangement of the buckets or receptaclesd and teeth c, as they may be arranged in other relations to each other; nor do I desire to limit myself tothe buckets or receptacles only in e,

combination with the teeth fc, 'as in some cases the buckets or receptacles -may be used alone, especially if they have toothed edges al. vThese buckets or receptacles and interpose'drows of 5o teeth c will `carry upward both long and short stock without any selection, and will produce a uniform mix or blend to be fed to the carding-machine.

The beater C, in lieu of the construction here shown, may consist of a wood roll with from the apron, so as vnot to fall down into vthe bin behind the apron. l 6 5 'In lieu of the rotary beater C, T may employ a reciprocating combor other device forvst'rip- The teeth c, upon or grooved roll,D, and by said roll is delivered onto a grating, f, over which it is spread, and 7o 'carried forward by a revolving beater orcylinder, E, which may be a toothed roll, a brush, a shaft with radial wings or bladesf or any other` suitable rotary device.

Just at the lower end of the gratingf is arranged the unal-feed roll F, and its companion rollers g, y', l1., and i. The roller g is a laproller, and as the wool leaves the grating f it is delivered by theroller g to the lap roller g, around which it is wound in a perfect, even, 8o and uniform lap. The roller t', which is preferably fluted or ribbed, pinches and holds the lap of wool on the lap-roller y, while the teeth of the final feed-roll F pull it off in even quantities,which aresubsequently deposited by the brush j upon the feed-belt or' other receiving device ofthe carding-machine. Y

Motion may beimparted to the several'parts by any suitable mechanism. That here shown well answers the purpose. s,

Upon one end of the shaft ofthe cylinder or beater E is secured a pulley, 7c, over which a driving-belt may be run. To the other end of said shaft is secured a pulley. k', which is connected by a belt, k2, with a large pulley, Z, on the same shaft-with a gear-wheel, l. The wheel Z engages with a gear-wheel, Z2, on the shaft of the iinal-feed.roll F and drives it, and from this cylinder or 'roll motion `is communicated to the rolls g g h z', as follows: At one lend of Ioo this shaft a gear-wheel, l, meshes with a pi'nion, Z, on the roll t, and pinion Z4 meshes with and 'turns pinion Z5 on rolllt. At the other end v'of the machine the shaft of the cylinder or roll F bears a pinion, m, which engages with pinion in on roller g', and m gears with pinion m2 onroller y. y Y Y v For driving 'the beater C, 'a pulley, n, is xed on its shaft, and connectedk by a belt, n', to a pulley, n2, on the shaft of beater E, While IIO for driving the brush j al pulley, n3, is con nected by a belt, n4, to a pulley, ni, on the shaft of the Abeater or cylinder E, which .conv stitutes the driving-shaft of the machine.

The lifting-apron B has its upper carrying- II5 roller, c, extended and provided with a pulley, o, over which a drivingbclt may pass.

What I claim as my invention, and desire to secure by Letters Patent, is i i 1. The combination, with a .bin for'stock,o'f 120 `a lifting-'apron provided with rows of teeth, 'and receptacles or buckets interposed between the teeth,- and mechanism for operating said apron and for delivering the material raised by the lifting-apron to4 aV cardin-g-engine or 125 other machine, 'substantially as specified.
