Mortenseu, Goshen, Nil-L, assignor to Don Woolen Company, Guild, N.H., a corporation of Delaware Filed Sept. 12, 1%2, Ser. No. 223,201 9 Claims. (Cl. 57--78) a broken end. If the hand brake is not released at the moment the piecing is about to be made, that portion of the yarn from the traveler to the pie cing zone will receive excessive twist and cause a defect or imperfection in the woven fabric at the place when the yarn has been over-twisted.

The present invention however provides for a device which may be actuated at a remote point as by the operators foot providing means for leaving both hands of the operator free to perform the piecing operation while controlling the rotation of the spindle, by the operators foot, whereby the rotation of the spindle can begin at the proper time and thereby eliminating such abnormal twist in the piecing of a broken end; and also the invention resides in the provision of such a foot-operated device which is easily applied to already existing spinning frames.

The invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly set forth in the appended claims.

Reference is to be had to the accompanying drawings, in which FIG. 1 is a plan view of part of one form of spindle rail of a spinning frame equipped with hand operated spindle brakes showing the application of the device thereto;

FIG. 2 is an elevational view looking in the direction of arrow 2 in FIG. 1, and

FIG. 3 shows certain details of the device looking in the direction of arrow 3 in FIG. 2.

Referring to the drawings, a plurality of spindles generally indicated at S, S are mounted on the spindle rail 10 and each spindle is provided with a brake actuated by a hand lever L. These parts are of a commercial type and in themselves form no part of the present invention and may be as disclosed in the aforesaid patent. The spindle rail may be stationary or movable.

Secured to one end of the spindle rail by screws 11 is a bracket 12 having an arm 1 3 extending therefrom and to which is secured by a nut 14 an air cylinder 15. The cylinder has a piston rod 16 which is connected as by a coupling 17 to a rod 18 that is supported by bracket 19 also secured to the spindle rail. Extending upwardly from the rod 18, adjacent each brake hand lever L are a series of posts 2%.

An air valve is attached by screws 31. to the back 32 of a support member 33 that is either secured to the frame work of the spinning frame or secured by bolts 34 to the floor on which the spinning frame rests. The air valve, provided with an inlet tube or conduit 35, is connected by

flexible tubes

36 and 37 to the air cylinder 15 at the opposite sides of the piston in the cylinder.

A stud 4t} projecting from the support 3'3 provides a pivot for a two arm lever which has one arm 41 in contact with the movable core 42 of the air valve. The other arm 43 has an elongated opening 44 therein to receive one end of a rod 45 that is supported in a bearing 46 in the 3,lil8,428 Patented Oct. 29, 1963 support 33. Spaced pins 47 projecting from the rod 45 straddle the arm 43 and a washer 48 and compression spring 49 are on the rod between the inner pin 47 and the bearing 46. The rod 45 is connected by a shackle 50 to one end of a wire cable 51 whose other end (not shown) is anchored as at the opposite end of the spinning frame.

When the spinning frame is in operation, air from the inlet conduit 55 passes through the valve 30 and into the tube 36 to force the piston rod 16 and the brake release rod 18 to the left as in FIGS. 1 and 3. Normally, the brake levers L are in the off position like the one associated with the spindle S in FIG. 1. However, when the yarn to a spindle breaks, the operator first manually swings the brake lever of that spindle into its braking position, like the one associated with the spindle S (FIG. l)- then the operator unwinds a suflicient length of yarn from the bobbin in order to connect the yarn on the bobbin with the yarn being delivered by the front rolls. Now, when the operator is ready to piece up, the operator steps on the cable 51 to pull the rod 45 to the left (FIG. 1) and svwng the lever arm 41 clockwise to push the valve core 42 inwardly. The air now passes into the tube 37 to push the piston rod and brake release rod to the right (FIG. 1) whereupon the post 2% strikes against the brake lever to swing it to its off position thereby allowing the spindle to rotate and the operator to make the piecing. As soon as the operator removes her foot from the cable 51, the spring 4% returns the lever arm 41 to its normal position. A spring inside the valve 3th automatically returns the valve core 42. to its normal position which allows the air to once more pass through the tube 36 to return the piston rod and the brake release rod to their original position as shown in FIGS. 1 and 3.

There is thus provided a simple and reliable device to release a spindle hand brake at any position along a spinning frame and whether the spindle rail is stationary or made to reciprocate.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. In a textile machine having spindles and a handoperated brake for each spindle, wherein said brakes are normally released and are thus in a certain predetermined position but are capable of being manually applied to the respective spindles for braking the same, that improvement which comprises an actuator and means to move the actuator in a direction to engage each brake and move it from a spindle braked position to a spindle release position, and remote control means for operating the actuator.

2. In a textile machine as recited in claim 1 wherein the remote control means includes a foot-operated device associated with the machine for the operation of the brake to its released position by the foot of the operator of the machine.

3. A textile machine as recited in claim 1 wherein each brake includes a manually operated lever andsaid brake releasing actuator comprises a member normally positioned in spaced relation relative to a respective brake lever, and the remote control means including means for operating the member to engage the brake lever and move it from said braked position to said normal spindle released position, said normal position being uninfluenced in any way by the operation of said actuator.

4. A textile machine as recited in claim 1 wherein each brake includes a manually operated lever and said actuator comprises an elongated rod, a series of spaced projections on the rod, said projections being placed so as to each engage a brake lever in braking position and move it to brake released position while failing to ina,..ea,sas

terfere in any Way with any brake lever Which is located in brake release position.

5. A textile machine as recited in claim 1 wherein each brake includes a manually operated lever and said actuator comprises an elongated rod, a series of spaced projections on the rod, said projections being placed so as to each engage a brake lever in braking position and move it to brake released position while failing to interfere in any way with any brake lever which is located in brake release position, and the remote control means includes a foot-operated mechanism for operating said rod to move it so as to cause said projections to engage brake levers in braking position.

6. A textile machine as recited in claim 1 wherein each brake includes a manually operated lever and said actuator comprises an elongated rod, a series of spaced projections on the rod, said projections being placed so as to each engage a brake lever in braking position and move it to brake released position while failing to interfere in any way with any brake lever which is located in brake release position, and the remote control means includes a foot-operated mechanism for operating salid rod to move it so as to cause said projections to engage brake levers in braking position, said footoperated mechanism comprising an elongated member extending substantially the length of the machine frame so that the operator can stand adjacent any braked spindle and operate the brake releasing actuator.
