STOP-MOTION FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 607,864, dated July 26, 1898.

Application nea August 27, 1897.

To all whom t may concern.:

Be it known that I, FRED LACEY, of Valleyeld, in the Province of Quebec and Dominion of Canada, have invented certain new and useful Improvements in Stop Motions for Spinning, Vinding, and Twisting Machines; and I do hereby declare that the folloWin gis a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to that class of mechanical devices called stop-motions, which are applied to various kinds of machines. In this case it is shown adapted to spinning, winding, and twisting machines.

It is fully explained and illustrated in this specification and the accompanying drawings.

Figure l shows the application of the stopinotion to a machine for doubling or twisting two or more yarns together. Fig. 2 is a top view ofthe stopping mechanism. Fig. 3 shows its application to a winding-machine.

It is not deemed necessary to set forth the necessity for stop-motions on this class of machines to those skilled in the art and for whom this description is intended, as the waste of material and injury to the thread resulting from running single7 or with less strands than required to make a perfect thread in the case of the twister or Winder and the waste of roving and the clogging up of the drawing-rolls in the breaking of the thread in the spinning are Well known. In Fig. l a set of three spools are shown holding yarn to be twisted or doubled into one thread, each set of three spools and spindle being operated independently of the other sets in the machine, so only one is shown.

a a are the rolls that draw the yarn d cl from the spools D D, held on the creel-board H, and deliver it to the twisting-spindle and bobbin, (not shown,) or, in case of a winding-machine, to the spool Y, Fig 5.

Between the spools D and rolls a is placed the stopping mechanism attached to the rail A. This mechanism consists of a standard g, secured by means of screws passing through the foot of the standard into the rail A. On

one side of the standard g a dogfu is held free slain No. 649,789. (No model.)

of the standard opposite to the dog is extended out to receive the drop-wires o', which are held in slots f, cut vertically across the extension h. The inner ends of the wires are bent into eyes that are held in the slots by a pin r, that passes through all of them, leaving the wires free to swing up and down on the pin. The wires o are bent down after leaving the standard and then up7 and an eye o" is made onthe end of each for one of the ends CZ to pass through. A horizontal pin 'L' is put in one side of a projection on the dog v and extends under the drop-wires o'. A horizontal'rod 7L is held in brackets j, attached to the side of the rail A, under which rod the Wires 0 pass, and arms B are secured to the rod n, extending along the frame to hold a wire s, that extends from one arm B under the drop-wires o to the next arm B for the purpose of lifting all the drop-wires at once when desired. The upper end of the dog@ is made heavy enough to overbalance its lower end when the drop-wires are raised by the yarns clear of the pin 7l; but when one of the wires drops on the pin its weight is sufticient to overbalance the upper end of the dog and cause the lower end to fall down in contact with the foot of the standard, it being too long to swing under the pivot clear of the toot. When all the yarns d are intact, the tension of the rolls ct in drawing them from the spools through the eyes o" of the wires and by the guide-pin c under the dog o will hold each wire up and allow the dog to trip back and give free passage t0 the yarns to the rolls; but if one of the spools runs out or a yarn breaks the drop-wire on that yarn will drop and push the dog down by the pin i, which will catch all the yarns between the dog and foot of the standard and hold them from going to the doubled strand with less yarns than are required to make perfect work.

In Fig. 3 the application to a Winder is shown, which is the same as the twister shown in Fig. l, only a wire 12" is inserted in the front ofthe dog o with a hook at its outer end to catch on the pins 0" c'", inserted in the ends of the short friction-roll d', that carry the spools Z', and stop the roll and spool when the dog o drops on the yarn.

IOO

Having thus described my improvements, I claim as my invention and desire to secure by Letters Patent- 1. In a stop-motion, the combination of a standard, a dog pivoted to said standard, the part of the dog below the pivot being longer than the distance between the pivot and the footof the standard, a series of drop-wires, a pin in said dog extending under said series of drop-wires to receive them when they drop, substantially as described.

2. In a stop-motion the combination of a standard, a dog pivoted thereto, the part of the dog below the pivot being longer than the distance between the pivot and the foot of the standard, a series of drop-wires, a pin fast in said dog and extending under said series of drop-wires, a rod held to turn in brackets and having an arm carrying a wire under the drop-wires to raise them when down and allow the threads to be pieced when broken, substantially as described.

3. In a stop-motion the combination of a standard, a dog pivoted to said standard, the part of the dog below the pivot being longer than the distance between the pivot and the foot of the standard, a series of drop-wires, a pin fast in said dog and extending under said drop-wires to receive4 them when they drop, a wire inserted in the front of said dog, and having a hook on its outer end to stop the roll and spool from winding in the end of the thread, substantially as described.

In testimony whereof I have hereunto set my hand this 6th day of July, A. D. 1897.

FRED LACEY.
