SPINNING-FRAME FOR FLAX, HEMP, J UTE, AND OTHER FIBERS.

Specification of Letters IPatent.

Patented May16, 191s.

Application filed March 14, 1913. Serial No. 754,342.

To all whom it may concern Be it known that I, Gnoa'on SHAW, a British subject, residing at Leeds, county of York, England, have invented certain new .and 'useful Improvements in Spinning- Frames for Flax, Hemp, Jute, and other Fibers, of which the following is a specification. i

This invention relates to machines for' spinning flax, hemp, jute and similar fibers to which a cop or bobbin building motion is applied. It is customary in these machines to raise the bobbin building rail by a cam acting through a long connecting chain and link to rotate the lifting shaft in one direction, but to allow the rail to fall by its own excess weight.

The object of this invention is to mount the camand a rack in such a way as to operate or rotate the lifting shaft in both directions and thereby completely control the movement of the builder rail in both the up ward and downward direction and by this means to obtain a quick traverse and a cross wind of the yarn on the bobbin. I

The invention consists essentially in arranging the building cam to act directly on a sliding raclvto move it positively in both directions, which rack in turnmeshes directly with'a'pinion on the lifting shaft of the machine to rotate it first in one direction and then in the reverse direction to impart a positive motion both up and down to the spindle rail.

The invention will be fully described with reference to the accompanying drawings.

Figure 1. is a transverse sectional elevation of part of a revolving ring and centrifugal presser spinning frame having the invention applied thereto. Fig. 2. is a part end elevation of same. Fig. 1s a sectional plant at one end of the machine.

The machine illustrated'is of the newest type of construction forjute spinning with crawing rollers A, revolving ring B, centrifugal presser l), spindle C and vertically reciprocating spindle rail D, said rail being raised by vertical racks E meshing with pinions e placed at intervals on the lifting shaft F of the machine. however, applicable to other ordinary types of spinning frames.

On one end of the lifting shaft F a sec ond pinion G is affixed. with which a re ciprocating sliding rack H meshes to give a The invention is,..

reciprocating rotary movement to the lifting shaft F.

The reciprocatingslidingrack H is preferably placed horizontal and is mounted in a guide casing h in the framing at one end of the machine, the said casing completely inclosing the rack, as will be understood from Figs. .2 and 3. The teeth of the reciprocating sliding rack H mesh with the pinion G on the lifting shaft F. "To the reciprocating rack H two rollers k andh? are fitted on studs h secured to the rack and project laterally from the same through slots formed in the innerside of the casing k. The lifting cam K is mounted to rotate between the two rollers 71, and if and is in conrack H first in one direction and then in the reverse direction. By this means a doubleacting movement is imparted to the rack and by it to the sp ndles, which movement is sensitive and positive lnboth directions.

' tact with both to impart movement to "the v The cam K is driven at a suitable speed from thefront delivery roller of the machine, or from any other convenient part by gear It is of heart or other shape togive a similar movement to the rack H, in both directions and shaped to prevent a dwell of the rack at either end. The rollers h and k with which the cam contacts are mounted on studs k which'are readily adjusted to maintain them in close contact with the periphery of the cam.-

I preferably suspend balanced weights WV to the lifter shaft to about counterbalance the weight of the spindle rails.

By thisarrangement I am' able to impart a long lift to the builder rails, and to drive same at a quick up and down speed, so as to produce a cross wound bobbin, and one which may be spun on the bare spindle, or on paper tubes, or on headless wooden bobbins.

WhatI claim as my invention and desire to protect by Letters Patent is 1. In a spinning frame, the combination with a vertical spindle, a rail carried thereby, a reciproeatory I vertical rack' bar to which the rail is directly connected, a horizontal lifting shaft and a lifting pinion pletely housed in said casing and movable in a horizontal plane therein, one end of said I ing a stationary axis and meshing with said rack bars whereby the vertical rack bar is reciprocated, guide means for said horizontally reciprocatory bar comprising a horizontally extending casing having its inner side wall longitudinally slotted, means for actuating said horizontally reciprocatory bar and means extending from said lastmentioned bar and in constant engagement with said actuating means.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. 1 GEORGE SHAW.
