FEEDING MECHANISlVI FOR CARDlNG-MACl-IINES.

SPECIFICATION forming part of Letters Patent No. 534,418, dated February 19, 1895.

Application filed February 11, 1893. Serial No. 461398. (No model.)

To all whom it may concern:

Be it known that I, EDDO V. BATES, a citizen of the United States, residing at Dracut, in the county of Middlesex and Commonwealth of Massachusetts, have invented a certain new and useful Improvement inFeeding Mechanism for Oarding-Machines, of which the following is a specification.

My invention relates to carding machinery and consists of devices and combinations hereinafter described and claimed, and includes an improved feeding apparatus for feeding slivers positively.

In the accompanying drawings on five sheets, Figure 1 is a perspective view of a carding engine provided with my improvements. Fig. 2, is a plan of the feed aprons, feed-rolls, tumbler, feeding-head or distributing carriage and actuating mechanism with parts of the frame; Fig. 3, a front elevation of the distributing carriage, a part of the frame on which it travels, a sprocket-chain which causes said carriage to traverse, and one of the side-belts; Fig. 4, a plan of what is shown in Fig. 3; Fig.5, a front elevation of a part of the frame on which thedistributi-ng carriage travels at the right of the machine, sh owing the gearing which drives the sprocketchain and rotatesthe shaft, by which the dis tributing rolls of the carriage are operated, showing also in front elevation one of the side-belts; Fig. 6, a plan of the parts shown in Fig. 5, omitting the side-belt; Fig. 7, arear view of the spur gears shown in Fig. 5, a part of the frame shown in Fig; 5, and the rotary shaft supported therein; Fig. 8, a left-side elevation of thedistributing carriage, its actuating gear and one of thefeed aprons, showing in section the carriage supporting-rail and the feed-table and the carriage operating shaft and sprocket-chain; Fig. 9, a right-side elevation of the carriage, omitting the stud on which the chain-engaging pin slides and' a cross section of the carriage-actuating shaft; Fig. 10, a horizontal section on the line 10 10 in Fig. 9. Fig. 11 is a central vertical fer-roll and the gears which connect said sideshaftand' the feed-rolls; Fig. 12, a plan of a part of the frame, a part of the main. cylinder audits shaft, the fast pulley and loose pulley on said shaft and a plan of the mechanism which drives the feed-rolls and the lumper-roll from the shaft of the lower doffer; also a part of said last-named shaft; Fig. 13, a side elevation of the link of the sprocketchain which carries a pin to engage the slide on the carriage. and a vertical section of said slide inthe plane of the axis of said pin.

In Figs. 1, 2, Hand 12, A denotes the frame of a breaker-card; B, the main cylinder; 0, the tumbler; D, the workers; D, the strippers; E,-the upper and E the lower doffer;

F, the rubbers or rub-rolls, between which the rovings pass from the doifers to the spools G, the latter being rotated by a frictional contact of said spoolers or of the rovings wound around them, with the drums H, these parts being all of the usual construction and operation as usedin wool-carding engines.

. The sliver-feeding devices hereinafter described are animprovement on the so-called Apperly feed, said Apperly feed being shown and described in United States Letters Patent No. 18;888,granted December 22, 1857, to James Apperly and William Clissold.

The frame a, represented in Fig. 2, supporting apron-rolls 'i 2". (Figs. 2 and 11), on which run, narrow feed-aprons I of card-clothing, the feed-rolls N N and the side-belts K, are of the usual construction and operation as-co'mmonly used in the so-called Apperly feed and are substantially as shown in said patent, except as hereinafter stated. Instead of the floor-delivery shown in said patent, an overhead delivery is now oommonly'usod, as represented in Fig. 1, consisting of a grooved pulley L, journaled in a laterally swinging arm and weight. I drive the carriage M by an endless chain M, running on the sprocket-wheels m m, the wheel in being fast on the same shaft 077. with the bevel-pinion m said pinion m being engaged by another bevel-pinion in, fast on the same shaft m with the spur-gear m said gear m being driven by a pinion m concentric with and turning with the bandpulley m and said pulley m being connected by a belt m with a band-pulley on fast on the shaft of the upper rear feed-roll N hereiuafter described (see Figs. 2 to 6), one link of the chain M having a pin m which enters a hole m in a slide m capable of moving vertically on a stud m fixed in the top of said carriage. (See Fig. 13.) The shaft on is by the means above described rotated at a uniform speed.

The guide-frame O is supported by vertical posts 0 on the frame a and consists of a bottom-rail 0 (Figs. 2 to 8), shaped in crosssection like an inverted T and having at its ends stands 0 0 in which is journaled a shaft 0 which guides and supports said carriage M and also drives distribu ting-rolls m m hereinafter described.

The shelf 0 or rear part of the base of the rail 0 supports standards 0 0 in which the shafts 122 771 of the sprocket-wheels m m are journaled, and which are secured to said rail 0 by bolts 0 which pass through said standards and through slots 0 in the vertical web 0 of said rail, said slots permitting the lateral adjustment of the standards when necessary to tighten the chain M or to adjust the position of the gears on the shaft m to the gears by which they are engaged. The tension of said chain M may also be varied by raising or lowering the idle sprocket-wheel m which turns loosely on a horizontal stud 0 rigidly secured to a plate 0 which, by means of bolts 0 passing through a vertical slot 0 in said plate into a standard 0 (substantially like the standard 0 and supported in like manner therewith), may be held at any desired height.

The carriage M (Figs. 3, 4, 8, 9, 10 and 13) consists of a vertical plate m having three backwardly-extending brackets m m m" rigidly secured thereto,the uppermost bracket 171. surrounding the guide-shaft O and having a sliding fit thereon. In the two lower brackets m m" is journaled a vertical shaft m having fast thereon a spur-gear 972 and in a swinging frame 977. pivoted between the brackets m m", is j ourn aled another vertical shaft m having fast thereon aspur-gear M caused to engage the gear 122 by a spring 001 secured to the plate m and pressing against said swinging frame (Figs. 8, 9 and 10). On the lower ends of the shafts m m are fast the fluted distributing-rolls m M which mesh into each other and pull the drawing L through a trumpet m of the usual construction, and deposit said drawing on the feedaprons I when said shafts m on are rotated as hereinafter described.

The carriage M is prevented from swinging forward by a guide-wheel m which is fast on the shaft on and presses against the front side of the vertical part 0 of the rail 0 The shaft 'm has fast thereon at its upper end, a bevel-gear m which engages a bevel-gear 0 which turns with the shaft 0 and also has a longitudinal movement on said shaft with the carriage M, said shaft having a key-seat 0 extending from end to end thereof, engaged by a spline secured in the hub of said beveled gear 0".

The shaftO'(Figs. 3 and 6) is rotated through a train of gears, as follows: The gear 0, fast on the shaft on of the sprocket-wheel m, and engaging the intermediate gear 0 the latter engaging the gear 0 fast on the shaft 0 and a bevel-gear 0 on said shaft 0 engaging a bevel-gear 0 fast on said guide-shaft O.

The shaft m is rotated through connecting mechanism above described from the shaft of the lower rear feed-roll N An arm 0 (Figs. 5 and 7), capable of swinging on the shaft 0 is held in the desired position by a bolt 0 which passes through a slot 0 curved concentrically with said shaft 0 said arm having also a straight slot 0 radial to said shaft o ,in whichslot the stud 0 ,on which said intermediate gear 0 turns, is adjustable in a well-known manner, so that either of the gears o 0 may be changed for a gear of a greater or less number of teeth to vary the speed of the distributing-rolls,and the amount of drawing deposited thereby on the feedaprons, the speed of the distributing rolls being regulated according to the speed of the delivery of the drawing L. I

In said Patent No. 18,888 are represented two levers, sometimes called latches, around the free end of which alternately is laid the bightof the drawing L, at the end of the traverse, to prevent the last delivered course of the drawing being pulled out of place by the tension of the drawing, each lever or latch being raised out of such engagement just be fore a new bight is formed. The rolls which in said Apperly feed, as heretofore used, most nearly correspond in position to my distributingrolls are not distributing rolls or feedrolls, being placed too far apart to exert any holding pressure upon the drawing and serving merely as guide-rolls or idle-rolls. The unequal contraction of the different courses or parallel lines of the drawing on the feedaprons causes the edges of the lap formed by said lines of drawing to be uneven and the outer slivers formed from said lap to vary so greatly in weight and size in different parts that these outer slivers, one at each side of the machine, are called waste slivers and are commonly returned to the first breaker after passing between the rub-rolls, the rovings formed from the waste slivers being too uneven to be spun. These latches lam enabled to dispense with, partly because I use the positively driven distributing-rolls m m which deliver the drawing uniformly atall times when the carriage M is traversing in either direction, and partly because'I lengthen the side-belts K, causing them to extend forward under the guide-frame O, as near as possible without interference, to the plane in which the rear faces of the distributing-rolls lie, so that the last-laid course of drawing will be caught between said side belts and the feed -aprons before a new course is laid. It will be understood that these side-belts K are parallel endless belts of card-clothing running on idle pulleys 7c and on other pulleys it fast on the shaft 10 the latter being provided with a fast gear 10 which engages a fast gear (not shown) on the shaft of the rear roll 01 of the feed-aprons I, in the usual manner.

Heretofore it has been customary to use a single pair of card-clothed feed-rolls N N to take the lap of drawing from the feed-aprons I and side-belts K (see Figs. 2 and 11), and deliver the same to leaders-in (not shown) or directly to the tumbler G, which in turn delivers the fibers to the main cylinder B. I arrange a second pair of feed-rolls N N, between said first pair and thetumbler, the cen ter of the roll N or lower roll of the second pair being at equal distances from the centers of the roll N N said second pair being precisely like the first pair, {but run at a higher rate of speed in order to draw the fibers and present them to the tumbler at right angles to the axis thereof, instead of parallel therewith, in order that the fibers may be placed straight on the cylinder B and to prevent the outer slivers from a variation in weight and size due to the irregular bending of the drawingL' at the sides of the lap. The upper front feed-roll N has a gear at which engages a precisely similar gear (not shown) on the shaft of the lower front feed-roll N in the usual manner, so that said front feed-rolls are driven at the same surface speed.

The shaft of the lower front feed-roll N is provided with a spur gear 'n'which engages a spur-pinion n secured to a bevel gear n concentrically therewith, said bevel-gear a eugaging a bevel pinion a fast on the front end of the side shaft 91 said side shaft having on its rear end another bevel gear n which engages a bevel-pinion a fast on the shaft 6 of the lower doffer-roll E, said lower dofferroll being driven through a belt and gearing from the shaft 13 of the main cylinder B.

The shaft of the upper rear feed-roll N is provided with a spur-gear n which engages a precisely similar gear atom the shaft of the lower rear feed-roll, so that both rear feedrolls have the same rate of speed (see Figs. 2, 11 and 12) and the shaft of-the lower rear feed-roll is provided with a band-pully n (Fig. 1) connected by a belt at with a pulley b fast on the shaft of the main cylinder. The roll N takes the fiber from the rolls N N and carries it up to the roll N which also cleans the fiber from the roll N.

The fibers are presented by the rear feedrolls to the tumbler O which runs at a greater rate of speed than said rear feed roll which delivers the fibers to the main cylinder B, as above stated, in the usual manner. In the angle below and between said tumbler and main cylinder I arrange a lumper-roll P, the same being covered with a card clothing and rotating in the direction shown by the adjacent arrow in Fig. 11, being driven by a belt 10' which connects the band-pulley 19 fast on the shaft of said'lumper-roll with another band-pulley 19*, fast on the shaft e of the lower dofler-roll E.

The lumperroll does not entirely strip the tumblerG but evens the stock on said tumbler, catching the bunches and surplus stock on said tumbler and pulling the bunches apart, the-adjacent surfaces of said tumbler and. lumper revolving in opposite directions. The lumper-roll is stripped by the cylinder B.
