MACHINE FOR HACKLING AND ENDING FLAX.

SPECIFICATION forming part of Letters Patent No. 625,036, dated May 16, 1899. Application filed May 27, 1898. Serial No. 681,941. (No model.)

To aZZ whom it may concern:

Be it known that LROBERT WILLIAM Knox, a subject of the Queen of Great Britain and Ireland, residing at Kilbirnie, Ayrshire, Scotland, have invented certain new and useful Improvements in and Relating to Machines for Hackling and Ending Flax and other Like Fibers, of which the following is a specification.

This invention has reference to improvements in and relating'to machines for hackling and ending flax and other like fibers.

Heretofore in this class of machines the ending or detaching 0f the endsof the fibers has been performed in such a manner that said ending takes place at one uniform length in all the sets of fibers.

By these improvements the fibers are ended or out off at Various lengths, according to the length of fibers inserted into the machine, and whereby loss of flax will be obviated and increased efficiency obtained. This is accomplished by having a reciprocating frame car--' Figure 1 represents an end elevation, and i Fig. 2 a side elevation, broken away, of the; ending part of a flax-hackling machine fitted i with my improvements, while Fig. 3 is asection of the slide-guides on the frame, taken on the line 3 3, Fig. 1; and Fig. tis a sectional detail.

Referring to the drawings, the flax Ct is inserted in a holder and channel A and also gripped between movable gripping-plates A, which are carried on a reciprocating frame A and moved downward until the ends of the fibers a pass between a pair of nipping or cutting-off rollers B or equivalent devices, where they are cut ofi, all so far in a usual manner.

By these improvements the ending is ef fected according to the length of fibers in the holderA without stopping the machine. This is accomplished by making the frame B, carrying the nipping-rollers B, toreciprocate or move up and down and cut off the ends of fiber according to the length of the latter. One means of effecting this, as shown in the drawings, would be as follows: A bar b, with an index-face b, rests on a bracket 12 on the frame B andfis mounted to work through a guide B in the frame A carrying the holders A, and opening and closing gripping-plates A. This bar Z) in the upward motionof the frame is carried upward, and as it lies parallel to the hanging fibers a in holder A the figures on the graduated index I) show the attendant at what length the fibers should be ended or cut off. A corresponding index bar or plate 0 is secured parallelly on fixed frame of the machine, and a pointer c" is mounted on the frame 13, carrying the nipping or breaking rollers B, which travel in front of this index. The attendant then turns a handwheel 0, which operates mechanism to raise or lower the frame B, carrying the rollers B, a distance corresponding to the figure at which the pointer o is opposite on index 0. This mechanism may consist of a spindle O, on the end of which the hand-wheel O is mounted, said spindle 0' having a pinion 0 gearing into a spur-wheel C on a short parallel spindle C and a toothed pinion-wheel C on this latter spindle C gearing into the teeth of a bar-rack C secured by lugs to the frame B, carrying the nipping-rollers B. Eccentric, lever, or other equivalent mechanism may be substituted to reciprocate the frame B. The gripping-plate guide-rollers F are mounted in brackets in the reciprocating frame B, one of them being counterweighted, so as to act on the plates A to grip the fibers a when ending these. Rods E are attached to the frame B by lugs e, and a rod 6 is connected from these duplex rods E to a band 6 which passes around a pulley E, and the other ping-rollers may be adjusted to various positions with respect to said gripping devices, substantially as and for the purpose set forth.

2.. In a machine for hackling flax or other like fibers, the combination with gripping devices, of a nipping device, movably mounted on the frame of the machine, mechanism for raising and lowering said nipping device with- 1 out stopping the machine, and means for indicating the position at which said nipping device must be fixed to out off the ends of the fibers held by the gripping devices with the least waste, substantially as described.

3. In a machine for hackling flax or other like fibers, the combination with gripping de- Vices, of a frame movably mounted on the frame of the machine, nipping-rollers carried by said movable frame, mechanism for reciprocating said frame Without stopping the machine, and means for indicating the position at which the nipping-rollers must be fixed for sets of fibers of different lengt-hs,whereby the ends of said fibers may be cut with the least waste, substantially as described 4. In a machine for hackling flax or other like fibers, the combination with gripping devices for holding the fibers, a movable frame,

nipping-rollers mounted in said frame, mechanism for raising and lowering the said frame without stopping the machine, a graduated index movable with the frame parallel to the fibers, a pointer carried by the frame and a graduated index on the fixed frame of the machine parallel to the movable index, on the latter of which the pointer indicates the distance above or below to which the nippingrollers must be moved for cutting each set of fibers, substantially as described.

5. In a machine for hackling flax or other like fibers, the combination with grippingplates for holding the fibers, amovable frame, nipping-rollers and guide-plate rollers car ried thereby, means for raising and lowering said frame to different positions with respect to the gripping-plates without stopping the machine, and counterweights for balancing said frame, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

R. W. KNOX.
