SPECIFICATION forming part of Letters Patent No. 611,338, dated September 27, 1898. Application filed September 29, 1897- Serial No. 653,438. (No model.)

To aZZ whom it may concern.

Be it known that 1, WILLIAM E. SHARPLES, of Fall River, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Spinning-Frames; and I do hereby declare that the following is 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 the arrangement of the mechanism for facilitating the doffing of the bobbins in ring-spinning machines.

The object of the invention is to afford simple, efficient, and inexpensive means for holding the ring-rail down while the full bobbins or cops are taken off of the spindles and empty ones put on. It is fully explained and illustrated in this specification and the accompanying drawings.

Figure 1 is a Vertical cross-section of the roller-beam, guideboard, separator-bar, ringrail, spindle-rail, and lower rail of a ringspinning frame with the stopping devices in elevation. Fig. 2 is a back elevation of the parts shown in Fig. 1. Fig. 3 is the same as Fig. 1, excepting that the arm that operates the stop-catch is attached to the thread-guidelifting rod instead of the separator-bar. Fig. 4: shows a back elevation of the parts shown in Fig. 3.

In the drawings, A denotes the roller-beam, and J the thread-guide board, usually made in section and attached to the roller-beam with hinges to allow of its being turned up out of the Way in dotting. ing along the front of the roller-beam, is held in bearings attached to that beam and has slips connecting it with the guide-board J, by which all the sections of the board can be raised at once by turning the bar, as in Fig. 3.

C is the ring-rail, supported on the vertical rods K, that slide up and down in holes in the stationary spindle-rail B and lower rail D. A catch II, consisting of a vertical bar bent in a semicircular shape at the top and having its lower end turned back at an angle to its middle portion, is held at its lower end on a pivot 01 in a step It, bolted to the lower rail D, preferably; but it may be attached to the under side of the spindle-rail A rod a, extend- B, if desired. This catch H is made of the proper length so that when the ring-rail G is clear down its upper end will swing over and rest on the middle of the ring-rail, as seen in Fig. 1. It has an adjustable weight 8 on its back or lower end that throws the catch back free from the rail 0, as shown. by the dotted lines, when not held forward by the arm F.

P is the bar that holds the separator-blades c. It is held on bearings at 0, so as to be capable of making a quarter-turn and hold the separators in a horizontal position when the machine is in operation (see dotted lines in Fig. l) or turned up out of the way when doftlng, as shown in the full lines. This bar P is made of a flat bar having a flange on each edge for strength and to receive the nuts of the bolts that fasten the separatorblade to it between the flanges out of the way and so they will not turn. To this bar P an arm F is attached, having a pin 01 in its free end so that when theseparator-bar is turned up with the separators for doffing the arm F will swing down and push the catch II by the pin t' over from the position shown in dotted lines to that shown over the ring-rail and hold it there until the bar P is turned out to a horizontal position again, when the arm F will be raised and the catch H. free to be thrown back by the weight 8 on its lower end.

The arm F may be put on the red at, that raises the guide-boards J, instead of the bar P, so that when that rod is turned to raise the guide-boards to dofi": the arm F will be turned down and push the catch 1-1 over the ring-rail in the same Way as when the arm is attached to the bar P, as described.

The operation of the mechanism may be described as follows: To doff, the first thing to do after the machine has stopped is to depress the ring-rail, whichis usually done by putting the foot on the weight-lever (not shown) that raises the ring-rail and pushing that rail clear down. Then the separator-bar P is turned up with the blades and the rod a turned to raise the guide-boards out of the Way of the bobbins to be taken off of the spindles. In case the arm F is on the separator-bar P it will be turned down and push the catch 1-1 over the ring-rail and hold it there, or if the arm is on the rod or, it will operate exactly in the same way. When the doffing is done, the foot is again placed on the weight-lever, the rod a and the bar P are turned down, which raises the arm F,whether on the rod or bar, and leaves the catch H free to be thrown back by the weight 8, and the ring-rail is allowed by the foot to rise easily to place again. I

Having thus described my improvements, I claim as my invention and desire to secure by Letters Patent 1. In a spinning frame, the combination with the ring-rail, of a curved catch pivoted to one of the stationary rails below the ringrail, and a movable rod or arm connected to the same moving part of the machine above the catch for pushing the hooked end of the catch over the ring-rail when that rail is depressed for the purpose of doffing, substantially as described.

2. In a spinning-frame, the combination with the ring-rail, of a curved catch pivoted to one of the stationary rails below the ringrail, the separators and the separator-bar to which the separators are secured an arm attached to the separator-bar and arranged to push the hooked end of said catch over the ring-rail when the.separators are turned up out of the way for doffing, substantially as described.

3. In a spinning-frame, the ring-rail, vertical rods upon which the ring-rail is placed, and a pivoted weighted catch having its upper end bent into a circular shape, and its lower end adapted to receive a weight, combined with the separator-bar, separators secured thereto, and an arm which extends downwardly from above the catch, and which by hearing against the catch holds its upper end pressed forward over the top of the ringrail, substantially as set forth.

4. In a spinning-frame, the separator-bar, the pivoted arm upon which the separatorbar is secured, and which arm has its lower end adapted to engage with the catch, and the separators secured to the top of the bar, combined with the ring-rail, the rods upon which it is placed, and a pivoted weighted catch having its upper end adapted to catch over the top of the ring-rail, and which catch is operated by the pivoted arm, substantially as specified.

In testimony whereof I have hereunto set my hand this 25th day of September, A. D. 1897.

WILLIAM E. SHARPLES. In presence of ALFRED H. H001), GEORGE M. H001).
