MACHINE FOR DRAWING OR SPREADING FIB RGUS MATERIALS.

SPECIFICATION forming part of Letters Patent No. 311,310, dated January 27, 1885.

Application filed February 24, 1882. Renewed March 14, 1884. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN GOOD, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Machines for Drawing or Spreading Fibrous Materials, of which the following is a specification.

My invention relates more particularly to that class of machines known as spreaders, used in the preparation of hemp and flax for spinning, but may be applicable 'to the drawing or spreading of other fibrous materials.

My invention consistsin an improvement on the machine which is the subject of Letters Patent of the United States No. 95,462, granted to me October 5, 1869. In such machine the drawing or spreading of the fibrous materials is performed by means of two or more endless belts or aprons furnished with combing or hackling pins, and arranged one before the other, and running at different velocities, the operating-points of the pins on the two belts being in or nearly in the same plane,and all said pins being presented in an upward direction during the time they are in operation. Such machines have proved very effective in their operation, because the two belts of pins traveling at different velocities thoroughly comb and straighten the hemp, flax, or other material during the travel of the fibers through or overthe frame or machine, and

' while the fibers are free at both ends, but are r the other belt, and consequently a break of such considerable length is left; between the working portions of the two belts that although the machine works well for a long fiber it does not work so well for shorterfiber.

The object of my invention is to bring the working-pins of one belt nearer to those of the other, and thereby cause a closer nip of the fiber to be taken between the pins of the two belts; and to this end the invention consists in inverting and raising one of the belts of pins relatively to the other; or, in other words, it consists in the combination of two belts of pins arranged one before the other and a machine embodying my invention.

one above the other, so that the pins which are at any time in operation are presented in a downward direction on the lower portion of the higher belt, and in an upward direction on the upper portion of the lower belt, and mechanism for moving the two belts in reverse directions, so that their operating or working portions will travel in the same direction, whereby I enable as close a nip of the fiber as is desirable to be taken between the pins of the two belts, and provide for a more nearly continuous operating surface.

The invention also consists in the combina tion, with feed-rolls, of two belts of pins arranged as above described when the belt ad jacent to the feed-rolls is arranged upon a higher plane than the belt in advance of it, and has its pins which are at any time in operation presented in a downward direction,

while the pins of the belt in advance of it are presented in an upward direction.

In the accompanying drawings, Figure 1 represents a vertical longitudinal section of Fig. 2 represents a plan thereof, and Fig. 3 repre-j sents a detail view of the adjacent portions of the two belts of pins on a larger scale.

Similar letters of reference designate corresponding parts in all the figures. A designates the feed-board, on which the hemp or raw material as taken from the bale, and without having recourse to lapping, is placed.

13 B designate the two feed-rolls, which are arranged at the inner edge of the feed-board, and the lower one of which, B, is mounted in stationary bearings, while the upper one, B, may be impelled against the lower one, so as to rotate by frictional contact with the material fed in by springs a, which bear upon its boxes, or by any other suitable means.

0 D designate, respectively, two endless belts which are armed with combing or hackling pins b. Only sufficientlength of the belts is fully represented to enable my invention to be clearly understood, while the remaining portions of the belts are represented in dotted lines. Each belt is composed of two endless chains having rods or bars 0 extending between them, and the rods'or bars have hackling or combing pins I) inserted in them entirely across the belt. The chains employed maybe of any suitable construction-such, for example, as that shown and described in Letters Patent of the United States No. 108,473, granted to me October 18, 1870 -and the lower portion of the belt O and the upper portion of the belt D are guided by tracks or ways (2, into which the ends of the rods or bars 0 enter, and by which they are guided. The belt 0 is carried by chain-wheels O, which engage with the rods or bars a, and are fixed 'upon shafts E E, which are arranged in the same plane. The belt D is carried by chain-wheels D, which engage with the rods or bars 0, and are fixed upon shafts F F, which are in a plane below that in which the shafts E E are situated.

G G designate pressing-rolls, into which the spread or drawn fiber is delivered from the belt D, and H H designate two deliveryrolls. In passing between the pressing-rolls G G the fiber enters a condenser, I, which gradually tapers or contracts toward the drawing-rollers H H, and which forms the fiber into a sliver, in which condition it passes between said delivery-rolls.

I will now describe how the various rolls and shafts of the machine are operated in this example of my invention, promising, however, that any other driving mechanism capable of imparting the necessary motions may be employed, if deemed desirable. The lower pressing-roller, G, forms the driving-shaft of the machine, and may be operated by a belt running over the pulley e, and from this shaft motion is transmitted to the lower drawing-roll by a belt, f. Upon the end of the shaft G is a pinion, g, which engages with a transmitting-wheel, g, and said transmitting-wheel engages with a wheel, on the shaft F and transmits motion thereto. By this means the belt D is moved in the direction of the arrow thereon in Fig. l and transmits motion to the shaft F.

Upon the end of the shaft F is a pinion, h, which engages with a transmitting-wheel, h, and through geared pinions k h (shown in dotted lines in Fig. 1) the motion is transmitted to a wheel, h, on the shaft E of the belt 0, By said belt motion is transmitted to the shaft E, and on said shaft is a wheel, i, which engages with a wheel, 6, on the lower feedroll, B, and drives the same. The several gear-wheels through which motion is transmitted to the operating parts of the machine are so proportioned that the belt D is moved at a much greater velocity than the belt 0, and therefore'the fibers are drawn from the belt 0 by the belt D, and are combed or straightened while they are free at their ends, and before they are taken hold of by the pressing or drawing rolls. The combing or hackling pins b of the belts O and D are so placed that on the lower or operating portion of the belt 0 the pins are inclined rearward, while on the upper or operating surface of the belt D they are inclined forward. This inclination of the pins is important, as it causes the fiber to be held closely against the belts and prevents the pins from throwing it off or dropping it, as they might if inclined in the opposite direction or set straight.

Adjacent to the several chain-wheels O D are cams J, with which the chains of the belts engage, and by which the pins are caused to be inserted and withdrawn from the material being operated on in a vertical direction, or lengthwise, which prevents the pins from lifting on entering the material or dragging on leaving it. The lower operating portion of the belt 0 and the upper operating portion of the belt D are in or nearly in the same plane, and there is so short a gap between the two that the operatingsurface formed by them may almost be considered as continuous, as seen clearly in Fig. 3. The pins of the belt D are inserted into the material almost immediately after the pins of the belt 0 are withdrawn, and hence it will be seen that the two belts of pins have a very close nip on the material. This enables Very short fiber to be worked in the machine, and tow may even be worked to bring it to the condition of a sliver.

The pins of the belt 0 while in operation are presented downward, while the pins of the belt D are presented upward.

WVhat I claim as my invention, and desire to secure by Letters Patent, is-

1. In a machine for drawing or spreading fibrous materials, the combination of two endless belts of combing or hackling pins arranged one before the other and one above the other, so that the pins which are at any time in operation are presented in a downward direction on the lower portion of the higher belt and in an upward direction on the upper portion of the lower belt, and mechanism for operating said belts, substantially as and for the purpose specified.

2. In a machine for drawing or spreading fibrous materials,the combination of feed-rolls, an endless belt of combing or hackling pins, having said pins presented in a downward direction on its lower operating portion for taking material from said feed-rolls, a second endless belt of pins arranged in advance of and below the first-mentioned belt, and having its pins presented in an upward direction on its upper or operating portion, and mechanism for operating said rolls and belts, substantially as and for the purpose specified.
