MEANS FOR STOPPING THE DELIVERY OF BOVING IN SZINITING MACHINES.
Application filed March 5, 192%.
To all whom it may concern Be it known that 1, PETER SHARP, a subject of the King of Great Britain and Treland, residing at Perth, Scotland, have invented certain new and useful Improvements in Means for Stopping the Delivery of Roving in Spinning Machines, of which the following is a specification.
This invention relates to rove stop mech anism for spinning machines and the object is to provide a simple form of mechanism for manual operation for stopping the delivery of the roving when a thread or threads break. and one which will prevent double spinning, since it enables the operative to expeditiously throw out of action all rove guides pertaining to broken threads and will permit said operative to again quickly and easily piece said threads.
The invention involves the use of a pair of feed rollers and a swinging rove-shifting member adapted to move the roving from normal feeding position to a non-feeding position with respect to said rollers, and comprises in combination with said elements, a manually operated device adjacent the roving, or each of same, and adapted, when manipulated on the breakage of the thread. to control mechanism for releasing said rove shifting member whereby the rove is shifted to non-feeding position.
In the accompanying drawings Fig. 1 is an elevation of part of a spinning frame showing two rovings and associated stop devices. Fig. 2 is a sectional side elevation thereof. Fig. 3 is a sectional elevation showing the rove shifting member and its release mechanism. Fig. 4 is a plan view thereof with part of the enclosing casing broken away, and Fig. 5 is a section on line 55 of Fig. 3.
The mechanism shown in the drawings embodies features heretofore devised by me in connection with automatically operating rove stops and especially as disclosed in the specification of my prior British Letters Patent No. 125682. in that it includes a rove shifting member in the form of a pivoted arm or lever a located above or adjacent the feed rolls b, b and adapted, when operated as hereinafter explained, to move about its pivot a and swing the rove 00, which passes through a guide a at the outer end of the lever, out of the nip of the corrugated part b of one of said feed rolls into a circumferentially grooved part b in the other roll Serial No. 695.9597}.
where no traction is exerted on said rove. The rove is at the same time lifted just clear of the drawing rolls 0, 0 (between which and the bobbin, not shown, the thread y has broken) so that no feed of the rove takes place until the operative again swings the rove shifting member a into feeding position.
According to the present invention T pro vide adjacent each roving 00, preferably at the part thereof between the feed rolls 6, b and the drawing rolls 0, c and between each of said rovings as it passes over the breast plate (Z usually arranged at this point a knob, button, finger piece or equivalent 6 within easy reach of the operative, this but ton or the like being connected by a rod, bar or other member 6 to mechanism adapted to release the rove shifting member a so that the latter, which is under the action of a spring or weight, as hereinafter described, will immediately move about its pivot a to swing the roving out of the nip of the feed rolls I), b as previously mentioned. There being one of these knobs and connections for each of the usual spindles and shifting member (a pertaining thereto. the operative can rapidly manipulate from the front of the frame those knobs which correspond to broken threads and thus immediately throw the respective rove feed out of action.
The rove shifting member a is as customary mounted in a casing f or in a frame which carries the release or trigger mechanism, and this mechanism in the example shown embodies a lever g to which the connecting rod 6 from the knob e is pivoted, this lever having a finger which acts on a catch it under the action of a spring 7L and which normally restrains from movement a link i into which slidably engages the inner end of the rove shifting member a, the said link being mounted on a spindle j having a notch -j normally engaged by the catch h and provided with an arm 7' under the action of a weight 7' Thus when the knob e is pushed in or otherwise manipulated the finger g is caused to lift the catch h so as to disengage it from the notch y' in the spindle 7', whereby the latter, and consequently the link 2', will be released, the weight 3' then pulling over said link and with it the rove shifting arm a to non-feeding position. When the operative throws the arm back again, the mechanism described will automatically retain it in feeding position to permit the rove as to be fed forward again to enable the thread to be pieced in the ordinary manner.
What I claim as my invention and desire to secure by Letters Patent of the United States is 1. In a spinning machine, the combination of a pair of coacting feed rollers; a swinging member adapted to engage the roving; a swinging link loosely engaged with said member; means connected with said link tending to positively swing it and with it the swinging member in a direction to shift the roving from feeding to non feeding position and to lift it as it reaches the latter position; a springpressed catch normally holding the link against movement; a releasing lever for said catch; and a manually-operated device connected to rock said lever.
2. Mechanism according to claim 1, in which the releasing lever has a finger which is disposed in position to contact with the catch and move it in a direction to release the link Mechanism according to claim 1, in which the link is attached to a rotary spindle having a notch wherein the catch is normally engaged, and in which said catch is lifted out of such engagement when the releasing lever is rocked by the manual device.
4:. Mechanism according to claim 1, in which the link is attached to a rotary spindle having a notch wherein the catch is normally engaged and in which the releasing lever has a finger underlying the catch, so that the latter is engaged and lifted out of the notch by said finger when the releasing lever is actuated.
In witness whereof I have signed this specification.
