FEEDING APPARATUS FOR MACHINERY FOR PREPARING FIBROUS MATERIALS.

SPECIFICATION forming part of Letters Patent No. 608,981, dated August 9, 1898; Application filed J'anuarylQ, 1897. Renewed June 3, 1898. Serial No; 682,505. (No model.)

To all whom it may concern:

Be it known that I,JOHN GO0D,of New York, (Far Rockaway,) in the county of Queens and State of New York, have invented a new and useful Improvement in Feeding Apparatus for Machinery for Preparing Fibrous Materials for Spinning, of which the following is a specification.

The improvement which is the subject of this invention is more especially applicable for the feeding sisal and other kinds of hemp the fibers of which are of considerable length, audit is applicable to any,machines"'such, for example, as spreading and drawing machines in which such fibers are subjected to the operation of devicescomprising pinsby which the said fibers are subjected to a combing or hackling operation.

An apparatus embodying the said improvement consists of a table comprising bars armed with pins, means of 'moving the said table in one direction, a fiber-feedin g carriage, and means for moving the said carriage back and forth over the said table for the purpose of depositing the fibers thereon in layers one upon another, with the'ends of the fibers of each layer lapping thoseof the layers above and below them; and the said improvement consists in certain combinations hereinafter described and claimed, of which such table and carriage constitute elements;

In the accompanying drawings, Figure 1 is a side View of a feeding apparatus embody ing my invention. f-Figrfl represents a central longitudinal vertical section, andFig. 3 a plan View of the same, Fig. 4," a side view showing some of the details on a larger scale than Fig. 1.

Similar letters and numerals of reference designate corresponding parts in all the figures.

A is the framing on or in which arethe bearings for the shafts a b, which carry the wheels 0 d, on which run the endless chains 13, which carry the transverse bars 6, which are armed with gill-pins "f; These shafts, chains, wheels, bars, and pins may be of any known or suitable construction such as is common to spreading and drawing machines,

and they are represented of well-known con of fibrousmaterials'such as struction, the bars in the upper run of the chains forming a platform or table from which the pins f project upward. The said chains and the train of bars and pins are to receive motion from any suitable source of power.

on the sidesof the framing A are ways G, which extend from points forward of the chain-wheels d backward some distance beyond the rear of the said chains, the said ways being parallel both vertically and laterally with the table or platform constituted by the straight upper run of the said chains and their bars 6 and pins f. On these ways G run a carriage D, in which is mounted the axle E of a reel or lantern-wheel E, which extends across thechains B. The height of this reel above the ways and the spacing of its rungs 25 are such that the rungs will enter between the rows of pins in the bars of the upper run of the chains B'and press upon a bed of fiber imposed'on the said bars, and that as the earriage D is'moved back and forth on the ways the reel maybe caused to rotate by the contact of its rungs with the said pins. The axle 8o E of the reel is so mounted in its hearings in the carriage that the reel may be capable of a suffioient rise and fall to accommodate itself to the thickness of the bed of fibers on the bars 6. The mechanism for producing the backward-and-forward movement of the carriage to roll the reel over the pins f may be of any suitable kind. Of the mechanism which I have represented for that purpose,

left hand threaded endless His a right and screw the shaft or core of which is fitted to turn freely, but confined. lengthwise, in fixed bearings u on the frame A. This screw, which is parallel with the waysG, isj fitted with a switch-nut I, which, by the continuous rota tion of the screw inone direction, is caused to run back and forth upon the right :and left hand threads. The said nut I is connected with the carriage D by a rod J. The screw II is represented as'furnished with a pulley mo 4), through which it is to be driven by a rap idlyrunning belt 10. The speed at which the The carriage D is represented as having a' counterbalance-weight K connected with it by a cord K running over guide-pulleys K This counterbalance is only rendered necessary when the chains and the carriage D are arranged to run at an inclination, as shown in the drawings, the counterbalance counteracting the tendency of the carriage to run downward; but this inclination of the chains and bed is not essential tomy invention, which would be just as well applicable in connection with chains the upper runs of which were horizontal, in which case the carriage would run horizontally.

Just behind the reel E there is arranged upon the carriage D a rising and falling or tilting feed-board F, which constitutes the principal feature of the present improvement. This feed-board is pivoted at its lower and forward end by a shaft F, which works in bearin gs 10 on the sides of the carriage. The said shaft F serves no other purpose than as a pivot for the upward movement of the feedboard to the nearly upright position shown in full outline in Figs. 1 and 2 and its downward movement to the nearly horizontal position shown in dotted outline in the same figures, in which latter position it is supported upon a rest F affixed to the carriage. In either of these positions the lower or front end of the feed-board is high enough to pass over the pins f. A little way behind the said shaft F a rock-shaft R is arranged in bearings 11 on the sides of the carriage D. This rock-shaft carries an arm R, on the end of which is an antifriction-roller 12, upon which the feedboard F bears, the purpose of the said rockshaft and arm being to tilt the feed-board from the rest F to the nearly upright position, and thereby to deposit upon the pin-bars the bunches of fibers which are placed upon the feed-board while it is in the nearly horizontal position. The said rock-shaft R is furnished outside the frame with a spur-gear 13, (see Figs. 1, 3, and 4,) which gears with a spurgear 14, turning loosely on a fixed stud 15, secured on the top of the carriage. On the same stud 15 there is loosely arranged a tappet 16, which when turned in the direction of the arrow shownin Fig. 4, by running against a fixed stop-pin 18 on the side of the framing A, is brought into action on a tappet-piece l7, affixed to the spur-gear 14, and turns the gear 14 in the same direction and so causes the latter to turn the gear 13 and the rock-shaft R in the opposite direction, and thereby to raise the arm R against the feed-board and so tilt the said board to the nearly upright position.

The tappet-piece 17 is extended backward in the form of a guard 17 to overlap the tappet 16 and protect it from lateral displacement. The rock-shaft R is furnished outside of the framing A with an arm, on which is a counterbalance R to the weight of the arm R and the feed-board. The rest F is furnished at the top with an india-rubber cushion 22 to prevent any violent concussion of the feed-board when it drops thereon.

This feeding apparatus is placed behind any suitable device for combing, spreading, or drawing fibers-as, for example, an endless train of pin-armed bars-and so placed its operation is as follows: An attendant takes in his hands a bunch of raw fiberssuch, for example, as the bunches in which the raw hemp comes in bales to the market-and while the feed-carriage D, with the feed-board F and reel E, is moving forward in the direction of the arrow 19, (shown in Figs. 1 and 2,) the feed-board being'in its nearly horizontal position on the rest F he places the fibers lengthwise along the board and spreads them to some extent across the same and leaves them there. As long as the carriage continues moving forward or in the same direction with the upper run of the bars 6 and pins f the feed-board remains in this position, the tappet 16 swinging back and passing freely over the stop 18 on the framing without producing any action on the gear 14; but after the carriage has moved backward in the direction of the arrow 20 a very short distance the tappet 16, coming in contact with the pin 18, is turned toward and against the tappet-piece 17 on the said gear 14, and so, as the carriage continues moving backward, turns the said gear 14 in the direction of the arrow shown upon it in Fig. 4, thereby turning the gear 13 and the rock-shaftR in the opposite direction and raising or tilting the feed-board. While the feed-board is thus'being tilted the fibers are shot or run freely by their own weight down the feed-board and so bring their forward ends under the reel E, which, being turned in the direction of the arrow shown upon it in Figs. 1 and 2, by its rungs coming in contact with the pins f as the backward movement of the feed-carriage continues, is caused to draw the fibers from the board and to deposit them upon the pins f. When the carriage has run some distance backward, the tappet 16 escapes from the pin 18, and the feedboard drops again to the rest F but this does not interfere with the drawing of the fibers therefrom and depositing them as hereinabove described. This operation is repeated during every movement of the carriage backward, and the successive bunches of fiber are thus superposed in several layers upon and between the pins f and upon the bars 6; but

as the chains B, with the said bars and pins, are continuously moving forward at a speed much slower than that of the carriage the several layers are superposed each some distance behind the next layer below, and so the ends of the fibers of the several layers overlap or break joint With each other, as indicated at 6 7 8 9 in Fig. 2. Thus in the very act of feeding the raw material it is so placed as to effect in a very considerable degree the essential object aimed at in all machinery for preparing fibrous materials-viz., the distribution of the ends of the fibers at numerous points in the length of the lap or sliver to be produced.

What I claim as my invention is- 1. The combinationof a table comprising bars armed With pins, means for moving said table in one direction, a carriage and means for moving the same back and forth over said table, a tilting feed-board on said carriage, and means for tilting said feed-board, sub stantially as herein described.

3. The combination substantially as herein set forth of a table comprising bars armed table comprising at. The combination of a table comprising bars armed with pins and means for moving the said table in one direction, a carriage and means for moving the same back and forth over said table, a tilting feed-board pivoted at its front end to said carriage, a rock-shaft on said carriage for tilting the rear end of said feed-board, a gear on said rock-shaft, a stud on said carriage, a loose gear on said stud gearing with said gear on the rock-shaft, a

loose swinging tappet on said stud for turning .a

said loose gear in one direction, and ,a fixed stop for actuating said tappet to produce the tilting of the feed-board during the backward movement only of the carriage, all substantially as herein described.
