JAMES ROBERTSON, OF WEST FERRY, NEAR DUNDEE, SCOTLAND.

FLIER SPINNING-FRAME.

Specification of Letters Patent.

Patented Dec. 1, 1908.

Application filed February 24, 1908. Serial No. 417,525.

To all whom it may concern:

Be it known that I, JAMES ROBERTSON, a subject of the King of Great Britain and Ireland, residing at Vinebank, West Ferry, near Dundee, in the county of Forfar, Scotland, have invented new and useful Improvements in Flier Spinning-Frames, of which the following is a specification.

This invention relates to flier spinning frames, and embodies improvements'in connection with my invention as set forth in my British Patent Specification No. 21331 of 7th December .1891 and consists of a yarn severing arrangement and a holdfast for the spindle.

In order that my said invention and the manner of'putting the same into practice may be properly understood, I have hereunto, appended explanatory sheets of drawings in which the same reference numerals are used to indicate corresponding parts in the figures shown.

Figure 1 is a front elevation of part of a spinning frame showing my invention applied thereto. Fig. 2 is a side elevation of a part of such frame looking on it in the direction of the arrow A. (Fig. 1.). Fig. 3 is a front elevation of part of a spinning frame showing my invention applied thereto and on an enlarged scale. Fi 4 is a part sectional elevation at B. B. Fig. 3) and Fig. 5 is a view looking on the back of the bobbin friction stop.

The yarn severing arrangement consists of a piece of narrow thin iron or steel plate or knife 1 extending the length of the carriage or in section to suit each bobbin and screwed on to each edge of the square tubular platform 12 in such a position that the yarn 2 passes over it and remains there when such platform is turned round a quarter turn after the bobbins 29 are full. (The arrow in connection with Fig. 4 shows the direction in which the platform turns when the empty bobbins are placed on their spindles from the front of the machine, the filled bobbins dropping off at the back. The machine works equally well nevertheless should the platform be made to turn in the opposite direction.) Into this steel plate or knife 1 small slots 3 may be formed nearly opposite each bobbin and the yarn naturally enters into these slots and will be severed as the, fliers 28 again revolve. This knife may also be made plain without slots so long as it performs the function of severing the thread.

hen performing the operation of changing the bobbins,the machine may be stopped with the fliers in the position shown by Figs. 1 and 3 and the platform 12 at its highest position, the yarn at that time being in correct position with regard to the cutting plate 1. On starting the machine each flier pulls the yarn against the plate and is cut, each bobbin at that time being kept from rotating by a pivoted and weighted friction stop 4;.

The holdfast for the spindle is a hook 5 which is pivoted on the flier rail of the spinning frame and is so arranged that it can be hooked into the leg of the flier 28 by the operator, after it has been stopped by the friction of such operators hand. It can be kept standing in the position shown by the dotted lines Figs. 3 and 4 as longas desired, the driving rope or belt simply slipping on its pulley at that time, the machine otherwise being in motion, thus allowing the operation of splicing a broken thread to be performed by the operator with ease.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is 1. A spinning and doubling machine comprising bobbins and fliers, means for operating them, a rising and falling bobbin support capable of being rotated, knives fastened on said platform and adapted to engage with the threads of a full set of bobbins when the fliers are stopped and the platform turned a quarter turn, so that said threads will be simultaneously cut when the fliers are again
