MACHINERY FOR SPREADING AND DRAWING FIBROUS MATERIEALS.

SPECIFICATION forming part of Letters Patent No. 497,237, dated May 9, 1893.

Application filed September 28, 1892.

To aZZ whom. it may concern:

Be it known that I, JOHN GOOD, a resident of Far Rockaway, inthe county of Queens and State of New York, have invented a new and useful Improvement in Machinery for Spreading and Drawing Fibrous Materials, of which the following is aspecification.

The object of this invention is to obtain in one machine by a continuous operation, a sliver of such quality as by the machinery heretofore used has required several machines and several separately performed operations to produce it.

I will first describe in detail a machine embodying my invention and afterward point out its novelty in claims.

Figure 1 represents a central vertical section of the machine and Fig. 2 a plan of the same.

Similar letters of reference designate corresponding parts in both figures.

A A designate the framing of the machine.

B B B B are four trains of gill-pin bars armed with gill-pins b b b b and carried by sprocket wheels on shafts o o* c 0 c 0 c 0 which work in bearings on the framing A A. These trains are arranged one before another. The two trains B B are of the same character commonlyemployed in spreaders as for example, in the spreader which is the subject of my Letters Patent No. 95,462, dated October 5, 1869, the second train 13 running much faster than the first train B. The two trains B and B are of similar character, the fourth train B running much faster than the third one B but they have their pins finer and closer together, and they may be as represented in Fig. 2, narrower than the first and second trains B B The third train B may run somewhat faster than the second 13*, but must not run slower. The third train 13 is set sufficiently in advance of the second B to make room between them for a conductor O which consists simply of a flat board having upwardly projecting sides a a which converge laterally toward the end of the board nearest the third train B Between this conductor and the second train B there is represented a pair of delivery rollers e e to take the fiber from the second train of pins and denial No. 447,187. (No model.)

deliver it tothe conductor, and between the conductor and the third train there is represented a pair of feed rollersff to take the fiber from the conductorand give itto the third train of pins. The delivery rollers 6 should run at a speed about the same as but not slower than the second train B and the feed rollers f at a speed about the same but not slower than the delivery rollers e, and not faster than the third train B In rear of the first train of pins there is a pair of feed rollers g and in front of the fourth train there is a set of delivery rollers h. There is also represented in front of the delivery rollers a condenser D.

The machine is represented as driven by a driving shaft E (Fig.2) which works in bear: ings in stands E. On this shaft is a pulleyz from which runs abelt to a pulley 7e on the shaft h of one of the delivery rollers h. The shaft it carries also a spur gearZ which gears with and drives one of two spur gears m n which are fast together and turn on a stud on the framing, the other of said two gears gearing with a spur gear 0 on. the shaft 0 of the fourth train of gill-pins B and so driving the said train. The shaft 0 of this train 13* carries a spur gear 10 which gears with one of two spur gears q r which are fast together and turn on a stud on the framing, the other of said two gears gearing with a spur gear 3 on the shaft 0 of the third train B and so driving that train, the shaft 0 of which is geared in a suitable manner with thafeed rollers f to drive the latter. The driving shaft E carries also a spur pinion it which gears with a spur gear a on the shaft of one of the delivery rollers e, and so drives the said roller which also carries a spur gear a which gears with and drives a spur gear 21 turning freely on a stud on the framing and gearing with a spur gear 20 on the shaft 0 of the second train B of gill pins and so driving the said train. The shaft 0 of this train carries a gear a: which gears with and drives one of two spur gears 00' 00 fast together and turning on a stud on the framing, the other of said two gears gearing with a gear g on the shaft 0 of the first train B of gill-pins and so driving the said train the other shaft 0 of which carries a gear 2 which is geared in a suitable manner with and drives the feed rollers g.

The several gears and pulleys hereinbefore described are relatively so proportioned that the trains are respectively driven at the speeds hereinbefore mentioned.

G G are two feed-boards upon which are to be placed two separate layers of fiber to be collectively supplied to the feed rollers g to be fed to the first train of gill-pins. The board Gis arranged in the way common to that of the single feed-board commonly employed in machines for spreading and drawing hemp and other fibrous materials, thatis to say, it is behind and has a downward inclination toward the feed rollers g, its lower end being opposite the opening between the said rollers so that the fiber deposited upon it may pass from it directly between said rollers. The-board G faces the board G,being arranged over the first train of gill-pins B with a downward inclination in the opposite direction to that of G, and its lower end terminates close above the feed rollers g. The layer of fiber deposited on this board G hasto pass over the top of and round the back of the-upper feed roller to enter between the feed rollers, its entrance being above that of the layer from G, as the two layers enter collectively between the rollers.

The operation of the machine is-as follows: The two layers of fiber deposited upon the two feed-boards and carried between the feed rollers are deposited collectively one superposed above the other upon the first train of gill-pins B, by which they are carried forward to the second train 13 a spreading operation taking place in a well known manner upon and between these trains, the single lap of fibers thus produced being delivered by the rollers 6 upon the conductor O above which it passes to the feed rollers f. In passing along the feed board thelap is contracted laterally by the tapering sides of the said board and is thereby thickened before being received between the feed rollers f which give it to the third train B by which it is carried forward to the fourth train B A second spreading operation takes place upon and between the third and fourth trains of pins and the lap taken from the fourth train by the delivery rollers h passes on to the condenser D in which it is converted into a sliver.

In the above operation the two layers of fiber superposed upon the first train of pins are more uniformly distributed than would be possible with a single layer of the same volume and hence a more uniformly spread thin lap is obtained from the second train, and this lap being contracted in width in passing through the conductor 0 is delivered to the third train with sufficient body or thickness to be properlysubjected to the operation of the pins of this and the fourth train by which it is again spread so that the resulting sliver delivered from the condenserD is very even and of very uniform thickness and quality.

What I claim as my invention is- 1. The combination of four endless trains of gill-pin bars and gill-pins thereon arranged one train before another the third and fourth trains having their pins set closer together than the pins of the first and second, mechanism for driving said trains all in the same direction the second train faster than the first the fourth faster than the third and the third not slower than the second, a feeding device for feeding fiber to the first train, a conductor with laterally converging sides between the second and third trains and a delivery apparatus for taking the fibers from the fourth train, substantially as herein set forth.

2. lhe combination with an endless train of gill-pin bars and gill-pins thereon and a pair of vfeed rollers for feeding fiber to said gillpins, of two feed-boards arranged facing each other for a double supply of fiber to said pair of feed rollers,substantially as herein set forth.

JOHN GOOD.
