BUTLER AMES, OF LOWELL, AND ARTHUR HARRISON, OF DRACUT, MASSACHUSETTS.
STOP-MOTION FOR COTTON ROWING AND SPINNING FRAMES.
Application filed January 15, 1913.
T 0 all whom it may concern Be it known that we, BUTLER Aims and ARTHUR HARRISON, citizens of the United States, residing, respectively, at Lowell and Dracut, in the county of Middlesex and State of Massachusetts, have invented cer tain new and useful Improvements in Stop- Motions for Cotton Roving and Spinning Frames, of which the following is a specification, reference being had therein to the accompanying drawings.
As is well known, a roving strand is made up by running two slubbing ends into one strand.
The general object of our invention is to stop the operation of the frame, upon the breakage of one of the slubbing ends, so that the broken end may be repaired. Stop motions have been employed heretofore for this purpose, but they have been of complicated construction, and, in many cases, inoperative, in the sense that they required constant attention from skilled mechanics; but the particular object is to simplify the construction and operation of prior devices, by reducing the number of parts. We attain this particular object by means of the principle of our invention, the best embodiment of which is shown in the accompanying drawings, of which Figure 1 is a plan of the structure; Fig. 2 is an elevation thereof; Fig. 3 is a sectional view showing the normal relations of the rocker-bar, drop-bar supported on slubbing end; Fig. 4 represents the position the parts assume upon the breaking of a slubbing end; and Fig. 5 shows how the drop-bar drops into the path of the vibrating rocker-bar, and stops and holds it.
In a suitable frame 1, is mounted a rocker-shaft 2, normally held in outward position by a rocker-shaft spring, not shown. To this shaft is fixed rocker-lever 3, the outer end portion of which has a screw 4 passing through a slot 5 in the outer end portion of the connecting link 6, the other end portion of which is pivoted to a crank on the delivery roll 7. This screw 4 also serves as a pivot for a slide-block 8 which has a pin 9 also free to move in this slot and which has an upwardly and out wardly inclined cam surface 10, Fig. 4. A trip lever 11 is pivoted to the connecting link 6, and has a correspondingly formed cam surface 12, Fig. 4, at its extreme outer end portion, to engage the cam surface 10 Specification of Letters Patent.

of the slide-block 8. Extending lengthwise of the machine is a shipper rod 13 having a limited longitudinal movement brought about by a spring 14, Fig. 1, engaging the frame 1 and a collar 15 on the shipper rod. In the top portion of this rod is a properly positioned lock-slot 16 to receive the bottom portion of a lock-bolt 17 properly mounted in the frame. The upper part of this bolt has a shoulder 18 overlying the trip lever 11. Parallel with the rocker-shaft 2 and above it, are fixed supporting plates 19 over which move the various slubbing ends 20, while between these plates, suspended from the slubbing ends, are drop-bars 21, held above but out of the path of a rockerbar 22, parallel with the rocker-shaft 2 and fixed thereto by rocker-arms 28.
When the machine is operated normally, the rotation of the front roll 7 causes the connecting link 6 to reciprocate and move the rocker-lever 3, the rocker-shaft 2, and hence the rocker-bar 22 inwardly against the action of the rocker-shaft spring, not shown, while the spring, during the opposite movement of the connecting link 6, holds the screw 4 in the rocker-lever 3 against the outer end of the slot 5 in the connecting link; the stop-block 8 and the trip lever 11 lying idle. The slubber ends being intact, the drop-bars as 21, Figs. 2 and 8, are held up, out of the path of the vibrating rocker-bar 22; but should one of the slubber ends break, one end of the drop bar 21, Fig. 5 would drop down into the path of the vibrating rocker-bar 22, and stop it, the slot 5, Figs. 2 and 4, in the connecting link permitting the arm to continue its reciprocation; but during this reciprocation, the trip lever 11, Fig. 4, moves with the connecting link 6, while the slide block 8 stays still with the rockershaft 2; hence the cam surface 12 of the trip lever moves up the surface 10 of the slide block 8, and in so moving, it engages the shoulder 18 of the lock-bolt 17, lifting it up out of engagement with the lock-slot 16 in the shipper rod 13, which is thus released, and forced by the spring 14 lengthwise, to cause the shipper rod to operate suitable shipping mechanism to stop the operation of the frame.
By repairing the broken slubber end, and remounting upon it the drop bar 21, the latter lies out of the path of the vibrating bar 22, Figs. 2 and 3; the screw 4 of the rocker-lever at once finding its seat at the outer end of the slot 5 in the connecting link 6 by reason of the rocker-shaft spring, not shown, always tending to move the rocker shaft 2 outwardly. But this always leaves the slide block 8 and trip lever 11 in normal position, Fig. 2, which permits the lock-bolt 17 to drop and engage the lock-slot 16 in the shipper rod 13, when it is moved longitudinally against the action of the spring 14, to start the frame into operation.
Having described the construction and operation of our invention, and desiring to protect it in the broadest manner legally possible, what we claim is 1. In a stop motion for roving and spinning frames, having a rocker lever, front roll with a crank, and a lock-bolt; a connecting link provided with a slot in one end portion to receive a pin in the rocker lever, the opposite end portion being connected with a crank in the front roll; a slide member, pivotally secured to the rocker lever and in movable engagement with the slot in the connecting link; a lifting member, pivoted to the said link; the slide member and the lifting member having engaging surfaces so that a movement of said members toward each other, will cause the lifting member to engage the lock bolt, and cause it to release suitable mechanism to stop the machine.
2. In a stop motion for roving and spinning frames, having a rocker lever, front roll with a crank, and a lock-bolt; a connecting link provided with a slot in one end portion to receive a pin in the rocker lever, the 0pposite end port-ion being connected with a crank in the front roll; a slide member pivotally secured to the rocker lever and in movable engagement with the slot in the connecting link; a lifting member, pivoted to the said link; said slide member being provided with a cam surface to engage the lifting member, and designed so that a movement of said members toward each other, will cause the cam to raise the lifting member into engagement with the lock-bolt, and cause it to release suitable meehanism' to stop the machine.

In testimony whereof We aflix our signatures in presence of two witnesses.
