HACKLlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 404,215, dated May 28, 1889. Application filed April 13,1888. Serial No. 270,604. (No model.)

making part of this'specification, and to the letj ters and figures of reference marked thereon.

Similar letters of reference indicate corresponding parts in all the figures of the drawings.

The object of my present improvements is to devise an efficient structure for combing and preparing manila, sisal, and American, Russian, and other hemp-or analogous fibers;

and my invention consists of certain novel parts and combinations of parts designed for this purpose.

The following is a description of the accompanying drawings, wherein is illustrated a machine embodying all the several features of my present inventionin combination. My invention is not confined, however, to the specific devices and combinations of devices illustrated and described herein.

The points of novelty which I desire to secure by this patent will be specifically pointed out in the claims concluding this specification.

Referring to said drawings, Figure 1 illus trates a side elevation of my improved hackling-machine with one of the side plates of the frame carrying the combing-chain removed, and certain parts of the structure broken away to illustrate more clearly the details thereof. Fig. 2 illustrates a part of the combing-frame and a part of the delivering and detaining cylinder, and Fig. 4. a part of the combingpins. Fig. 3 illustrates a carrying-wheel and part of the combing-chain and the guide at the delivering end of the combing-chain, by means of Which the individual teeth are given an inclination which causes them to withdraw from the hemp and permit it to pass out through the delivering-rollcrs. Fig. 5 shows the detaining-cylinder and the guides in detail near the same, by means of ing a cross-section of the device shown in v Fig. 6.

Referring to Figs. 1 and 5, A A are a pair of feed-rollers, through which the hemp is fed into the machine.

B is a wheel or cylinder, the periphery of which is provided with radial slots or tracks 0 C. In each of these slots a bar, D, furnished with pins D, is set, which is caused to travel radially out and in as the wheel revol ves, by means of any suitable device, such as stationary side plates of the wheel B provided with grooves U. These bars are caused to slide in said radial slots as the wheel revolves, so that the pins as they pass the feedrollers will be projected to penetrate and firmly engage the hemp entering the machine and carry it around to the hackling-frame.

This device is illustrated in detail in Figs. 5 and 6, in which X is a stationary plate keyed to the stationary axle V by the key W, and having cutupon its face the groove U.

E is an apron set below the Wheel Band extending from the feed-rollers to the combingchain to prevent the fiber dropping away from engagement with the detaining-pins D.

F is a frame in which the carrier-whee1s G G are set.

H is a linked chain carrying bars I, furnished with pins 0 0. (See Fig. 4.)

I are guide-dogs set on each end of the bars I, and J J are pegs set in the guide-dogs I.

K, L, M, and N are guides to direct, by means of the dogs in the ends of the bars I, the inclination of the pins 0.

P P P P are delivery-rollers, by means of which the fiber is discharged from the machine.

Power is applied to the machine through the shaft U", carrying the pulley U. On the same shaft and keyed to it isa gear-wheel, T, meshing with the teeth of the gear-wheel Q, which gears into the wheel R, and which latter in turn drives the delivery-rollers P P. By means of a belt, Z, power is transmitted from the pulley U to a pulley, V, which actuates a shaft, W, to which the gear-wheel \V is attached, the teeth of which last-mention ed wheel mesh in a gear-wheel, X, keyed to which is a pinion, X, which meshes with gears on the detaining-cylinder 13.

The operation of the machine is as follows: Hemp is fed in between the rollers A A, where it is caught by the pins 1), which are caused to project and pierce the mass of the fiber as it leaves the rollers and penetrate through its entire depth down to the apron E. As I have said, any suitable device may be employed to cause the pins D to advance and retreat such, for instance, as the stationary groove 'l, with which the laterally-projecting pegs at the ends of the bars I) engage, and by means of which their degree of projection at any position is definitely determined. For reasons hereinafter more fully pointed out, I prefer to have the wheel. 13 and the hackling-chain F placed near together as possible. For the purpose of avoiding interference with the guide-dogs I on the hackling-chain, l have illustrated these pins 1) being withdrawn or as retreating as they approach the hackling-teeth. Now as the fiber is carried forward by the revolution of the wheel I it is caught by the haekling-teeth O, which are moving at a higher velocity than the pins 1), the effect of which is to comb the fibers, the function of the pins 1') in this operation being to hold the fibers while they are being operatcd upon by the teeth 0.

Referring to the hackling device, it will be observed that as the guide-dogs I, attached to their several pivots on the flexible chain ll, approach the wheel. G (partially broken away in. Fig. 1, but shown in full. in Figs. 2 and 5) the project-ions J strike the guide N, an d as the bars progress the teeth are inclined forward more and more in the direction of their motion, so that they can approach very near to without interfering with the apron E or the detaining-cylinder. hen they meet the hemp which is being carried slowly forward by the wheel 13, their inclination is such that they readily penetrate and comb it throughout its entire mass. \Yhenthe guide dogs I arrive at the end of the guide N, the pins J strike the track K and the pins J pass in front of the end of the guide N, engaging with the track L. From the time these bars leave the carrier G until they reach the carrier l their position is determined by the tracks K L, and as long as they are operating upon fiber which is still held by the detainingcylinder the teeth are inclined forward, thus preventing the fiber riding up over the top of the teeth. At the upper part of the frame is a guide, M, which engages with the pegs J on the longer arm of the dogs, by means of which the teeth are inclined backward, or in a direction opposite to their motion, so that they are automatically drawn out of engagement with and cease to operate upon the fibers, which are then caught and led out of the machine by the delivory-rollers I, while the chain at this point is describing the arc of a smaller circle. The inclination of the pins backward, or in a direction opposite to their motion, serves to prevent the deliveryrolls, which preferably move faster than the combing-chain, from drawin the fiber up and over the combing-teeth. On the contrary, the inclination of these teeth is such that the fiber is held by them and combed by being drawn through them by the delivery-rollers, the combing-teeth acting at this time in a sense as detaining-teeth. The combing-teeth are preferably made to incline forward as long as the fiber which they are acting upon is held by the detaining-tee th 1'), and are made to incline backward as soon as the fiber which they are acting upon is caughtbetween the delivery-rollers. This is an important feature of my present invention.

It will of course be understood that in operation the wheel 13 turns with a left-hand revolution, while the hackling-ehain ll is propelled by a right-hand revolution of the carriers G G, so that where the two approach each other the direction of their movement is the same while their velocities differ, the hackling-chain moving much faster than the detaming-cylinder.

The advantages of my improved hacklingmachine over all others in use are, among other things, that by the peculiar design, relat-ion, and coi'istruction of the detaining and hacklin g devices I am able to bring their teeth close together, and, indeed, if desired, and as illustrated in the drawings, have them intersect, thus avoiding the possibility of any hemp escapin g without being properly combed throughout its entire length by the hackling-teeth, while the shape of the path which the hackling-chain follows, as well as the arrangement and inclination of the teeth, avoids the danger of carrying the stock past the deliveririg-rollers, and thus preventing its discharge from the machine. It also prevents the stock being drawn by the delivery-rollers over the top of the combing-pins.

It will be observed that the hacklingchain describes an irregular curve. At the pulley G the chain describes the arc of a small. circle. As it rises above said pulley its path is a curve ap n'oximating the curve of the periphery of the detaining-cylinder. It then follows the are of a larger circle, rising above the detaining-teeth and approaching the delivery-rolls. At this end the chain again describes the arc of a smaller circle, and by any suitable path returns to the pulley G. This path substantially is what I call an irregular curve. By this irregular-curved course I obtain all the advantages of having the combing-pins travel in a long rising curve from the detainingnns toward the delivery rollers, and also am enabled to have both the detaining-pins and the deliver -rollers set very near to the path of the hackling-chain a matter of considerable importance in this class of machines, since it enables the device to comb the iiber perfectly from end to end and to readily feed and strip the fiber.

ITO

My improved machine is obviously capable of various modifications without departing from the general principle and scope of my invention, and my various improvements may be employed separately, instead of in combination, as illustrated and described.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a hackling-machine, the combination of delivery-rolls, advancing and retreating detaiing pins, means, substantially as described, for carrying said pinsand causing them to advance and retreat, a chain carrying combing-pins, and guides for controlling the movements of said combing-pins, whereby the said pins are inclined to facilitate their entrance into the fiber held by the detaining-pins and moved into position to hold the fiber properly against the action of the delivery-rolls while being withdrawn thereby from the combing-pins, substantially as described.

2. In a hackling-machine, the combination of detaining-pins, means, substantially as described, for carrying said pins and causing them to advance and retreat, deliveryrolls and a hackling-chain following the path of an irregular curve, at one point approaching and approximating the path of the detaining-pins and afterward approaching the delivery-rolls in an arc of reduced radius, and guides for causing the chain to follow said path, substantially as described.

3. In a hackling-machine, the combination of advancing and retreating detainingpins, means, substantially as described, for carrying said pins and causing them to advance and retreat, a chain carrying combingpins following the path of an irregular curve, at one point approaching the detaining-pins in an arc of reduced radius and afterward approaching the delivery-rolls in an arc of reduced radius, delivery-rolls, and guides for controlling the movements of said combingpins, whereby said pins are inclined to facilitate their entrance into the fiber held by the detaining-pins and moved into position to hold the fiber properly against the action of the delivery rolls while being withdrawn thereby from the combing-pins, substantially as described.

4. In a hackling-machine, the combination of a revolving cylinder, detaining-pins carried by said cylinder, and a hacklingchain traveling in a path approximating the curve of the periphery of said cylinder at the points where the detaining-pins and combingpins meet, and guides for causing the chain to follow said path, substantially as described.
