SEPARATOR FOR SPINNING-FRAMES.

SPECIFICATION forming part of Letters Patent N 0. 542,649, dated July 16, 1895. Application filedMerch 19,1395. S ia1No.54 2,362. (No 11101181.)

To aZZ whom it may concern.-

Be it known that I, ARTHUR MASON, a citizen of the United States, residing at Taunton, in the county of Bristol and Commonwealth of Massachusetts, have invented anew and useful Improvement in Separators for Spinning-Frames, of which the following is a specification, reference being had to the accompanying drawings, which form a part hereof.

The object of my invention is to construct a separator in which a wide blade may be used for long winds as conveniently as a narrow blade, and which shall at all times be within a perpendicular line from the face of the ring-rail also, to cause the separatorblade to be automatically thrown down again when the machine starts after the blades have been lifted for doffing or other purpose, and to provide a counterbalance for the separator-- blades, which shall serve also as a stiffeningro My invention consists in a pivoted trippinglever connected with the wave-rocker and actuated by the wave-rocker to trip the separator and throw it from an upright position into its operative position before the levers carrying the separator-blades are turned on their pivots; also, in, certain adjustable features of the levers and in making a counterbalance,

which serves also as a stiffening-rod and bears against the salnson as a stop, and in other features which will be more particularly described and claimed.

In the drawings, Figure 1 is a cross-section through the roll-beam, showing an end elevation of so much of a spinning-frame as is necessary to illustrate my invention. Fig. 2 is a section through the dog on the wave-rocker rail S, ring-rail S, andlower rail S are common, and power is applied inthe usual manner. The samson M supports the roll-beam and other parts of the spinning-frame.

Secured to theroll-beam A is a bracket D, having an elongated slot d, .in which is clamped a stud J, which forms a pivot for the bent lever O, at the forward end of which is pivoted the separator O. The bent lever E is also pivoted on the same stud J, and has-an extension E, with a slot 6, through which a bolt 6' passes, bolting the two levers E and 0 together, so that they move on the pivot as one lever. The toothed indicator L engages with the toothed segment K, and is set in the proper notch before the bolt 6 is set up. By observing the position of the pointer on the segment all the separator-levers in the line can be set at exactly the same position.

The stiffening-rod H runs the length of the machine, resting on all the levers E in the line, and is clamped to each one by a dog G. This serves to hold them all at a uniform position and serves also as a counterweight. It is so adjusted that the blades will over- -weigh the rod H sufficiently to assure that the separator-blades will fall by their own weight when the wave-rocker shaft W turns in its bearings R and relaxes the strain on the rod Q, the samson on M serving as a stop.

The wave-rocker W is actuated through the rocker-armX and reciprocating-shaft Y.

The tripping-lever B, which throws down the separator in the manner which will be described later on, is pivoted to the lever O at b, and at its rear end is a stud b, which plays up and down in a vertical slot 12 in the arm 0 of lever O, the tripping movement being given by the wire rod Q, actuated by the rocker-shaft W.

The separator O is clamped to the holder I by screw-bolt O, which passes through an elongated slot 0 in the bent shank O of the separator. This holder consists of a sheet of metal having a series of elongated slots t', through which the screw-bolts 0 pass, the separator thereby being capable of delicate adjustment to the proper alignment for its throw between the bobbins.

The pivot P by which the separator is pivoted to the lever O is secured in the bracket P, which is also clamped to the holder-plate I by the screw-bolt O. I prefer to make this holder-plate I of corrugated sheet metal, because it is light and is sufficiently strong for the purpose and is of a form which will be readily engaged by the tripping-lever B. This tripping-leverB has-an upturned end B, which, when the lever B is pulled down by the rod Q,bears up against the holder I on one side of its center and throws it over on its pivot.

The wire rod Q is adjustable in length by means of the turn-buckle QT, and at its lower end it is fastened to a chain V, which is socured to the dog F on the rocker-shaft W.

During the operation of winding the separator is between the bobbins, as shown in fulllines in Fig. l. The holder-plate I strikes on a shoulder C on the lever C to prevent turning too far down on its pivot and the rod Q should preferably be adjusted in length so that the separator shall at all times be. held out of contact with the. ringrail. As the. rocker-shaft R rocks, giving the up-and-down movement to the ring-rail, the. chain V will wind and unwind over the deg F and give a. reciprocating movement to the rod Q, thereby turning the levers E and B. on their pivot and causing the separator O to alsorise and fall at a corresponding rate of speed as the. ring-rail. hen dotting the separator is thrown back on its pivot and maycome u p. against the roll-v beam. Heretofore when a wide separator is used, which is attached to the roll-beam as it projects out over the path of thering-rail, if'the operator forgets to throw the separator dew-n again after dofflng and before starting up the machine the rail will strike the separator and breakage of something will take place. In my device the separator need not be thrown back by hand. As soon as the machine starts the. rocker-shaft R turns, Winding the chain and pulling down the rod Q as soon as. itsis in its lowest position as regulated bythe rod 1-1 when it bears up against the. Samson, and the slack should not be so great but that it will be all taken up, at the. proper time for trippingthe separator when the ring-rail rises again.

What I claim is 1 In a spinning frame, the combination of a separator, a separator lever towhich; the separator is pivoted,,a supportin which the separator lever is fulcrumed, mechanism and. causes the separator to. rise in ad vanoe of the ring rail when the separator is in its op.- erative position between twov bobbins, and a tripping device which, throws the separator down into its operative position between the bobbinsv before the separator lever turns on its fulcrum to lift the separator, substantially as described.

2. The combination of a separator, a sepa rator lever, a fulcrum for said lever intermediately between its ends, a tripping lever and a fulcrum for the tripping lever intermediately between its ends, a rod pivoted at its upper end to the rear arm of the tripping lever and to the rear arm of the separator lever, the pivot for said rod having play in a slot in the separator lever, a wave rocker, said rod having at its lower end a flexible connection with the wave rocker whereby, when the rocker turns, the tripping lever will be turned onfiits fulcrum to throw the raised separator blade into operative position, before the separater leverbegins to move onits fulcrum, suba; fulcrum for the tripping lever intermediately between its. ends, a rod pivoted at its upper end to the rear arm of the separator lever, the pivot for said rod having play in a slot, in the separator lover, a wave rocker, said rod, having at. its lower end a flexible connection with the wave rocker, and a cam dog on, the rocker which guides the flexible portion whereby, when said rocker turns, thetripping lever will be turned on its fulcrum to throw the raised separator blade into operative position, substantially as described.

4. In a spinning frame, the combination of a. Series of separator levers, a series of brackets in which the separator levers are fulcrumed, a. series of separators pivoted to the forward arms of said levers, and a stiffening rod which serves as a. common counterweight for said separators adjustably secured to the rear arms of said levers, substantially as de scribed.

5 A separator lever composed of two bars having overlapping ends. bolted together, a

toothed segment on one bar and av toothed guide on the other engaging in said toothed segmentwhereby the, two bars. maybe set at Various angles to eachv other, substantially as described.

6. In a. spinning frame, the combination of a series of brackets supported from the roll beam, a series, of separatorlevers pivoted in said brackets, a stiffening rod extending transversely of all the separator levers in said seriesand serving as a common counterweight, and a. series of dogs which clamp said rod to the levers, substantially as described.

7. In aspinning frame, a series, of separators each, having a bladeO and a bentshank 0- formed. with flanged sides an dan elongated which turns the separator lever on itsfulcrum slot. 01 in combination. with av corrugated jmetal holder I embraced by the separator shanks, and having, aseries of elongated slots which register with the slots in the separator shank, and bolts which pass through said slots holders, a bracket P also bolted to the sepa rator holder, and a separator lever to which the bracket is pivoted substantially as described.

9. The combination of the bent levers C and E bolted together and forming a lever for the separator blade, a movable pivot on which said levers are fulcrumed, and a tripping lever pivoted to the separator lever, substantially as described.

10. The combination of the bent levers O and E bolted together and forming a lever for the separator blade, an adjustable pivot on which said levers are fulcrumed, a toothed segment and indicator whereby the two levers C and E maybe adjusted to different angles with relation to each other, a tripping lever pivoted to the compound separator lever, a rod H which is adjustably secured to the rear arms of a series of separator levers and which serves as stiffening rod and counterbalance, and which bears against the samson which forms a stop, substantially as described.
