ROVING STOP MOTION FOR SPINNING FRAMES. APPLICATION FILED L29. 1921-.

GREGORE K. KAPATAS, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR 0F ONE-HALF T0 JOHN EDWARD MULHOLLAND, 0F PRQVIDENGE, RHODE ISLAND.
ROVING STOP MOTION FOR SI INNDTG FRAMES.
Application filed April 29, 1921.
To all whom 2'25 may concern Be it known that I, Gnneonn K; Karnrns, a citizen of Greece, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Roving Stop li-Iotions for Spinning Frames, of which the following is a specification.
In the usual construction of spinning frames the roving, when breaking in front of the top rolls, will usually wind up on the rolls or feed out of the rolls and snarl up on the bobbins or adjacentroving, also the roving may run to waste a considerable length of time before being noticed by the operator, thereby causing a material amount of waste.
The object of my invention is to improve the construction of a spinning frame, whereby when the roving breaks in or in front of the drawing rolls, it will be automatically held or broken, back of the top rolls, thereby preventing the feeding of the broken roving through the rolls.
My invention consists in the peculiar and novel construction of a roving stop-motion for spinning frames, whereby when the roving breaks between or in front of the drawing rolls it will be automatically stopped from feeding through the rolls, said stopmotion having details of construction, as will be more fully set forth hereinafter and claimed.
Figure 1 is a front view of part of spinning frame provided with my improved roving stop-motion and showing the top rolls removed.
Figure 2 is a side view of Figure 1 partly in section and showing the roving stop-motion engaging with the roving in its normal position in full lines, and in the position it would assume in stopping the roving from feeding through the drawing rolls, in dotted lines, after the roving has broken or separated, and
Figure 3 is a top view of my improved roving stop-motion, enlarged relative to Figure 2.
In the drawings 4: indicates a portion of a spinning frame having the usual drawing rolls 5, eye 6, ring-rail 7, ring 8 bobbin 9 and spindle 10 operated in the usual way and 11 my improved roving stop-motion. The standard for the drawing rolls 5 carries the usual round standard 12- roving Specification of Letters Patent.
Patented Jan. 3, 1922.
Serial No. 465,511.
R comes from the usual quills, not shown, over the round bar 12, through the drawing rolls 5, the eye 6 and ring 8, as shown in Figure 2 and is then wound on the bobbin 9, in the usual Way. My improved roving stop-motion 11 consists of a vertical pivot support 13 secured to the frame 4 under the drawing rolls 5. A light normally horizontal rod 14 is pivotally secured intermediate its length, to the upper end of the support 18 and a light normally horizontal rod 15 having a forked forward end 16 is pivotally secured at its inner end to the forward end of the rod 14, a finger 1'7 on the rod 15 extending under the end of the rod 14 holds the rod 15 from dropping downward and allows for raising of the rod 15, for dotting. A weight 18 is adjustably attached to the inner portion of the rod 14 for adjusting the tension of the forked forward end 16 on the roving. A vertical tubular rod 19 is pivotally secured at its lower end to the rear end of the rod 14 and carries a rod 20 which is adjustably secured in the tubular rod 19 by a set screw 21, and on the upper end of the rod 20 is fixed a curved clamping member 22 shaped to fit over the round bar 12, when in operation.
When in use, the roving R passes under and between the curved clamping member 22, and the standard bar 12, through the drawing rolls 5 and then down over the forked end 16 of the rod 15, the tension of the roving holding the rods 14 and 15 down and the clamping member 22 up away from the bar 12. Then the roving breaks in the drawing" rolls or in front of the drawing rolls, the tension of the roving is removed and the rods 19 and 20 dropping by gravity assisted by the weight 18, brings the curved clamping member down into engagement with the round bar 12, thereby clamping the roving between the curved clamping member and the round bar, and breaking the roving, before it can enter the drawing rolls, and preventing waste of the roving, and possible damage to adjacent roving/{and bobbins.
y improved roving stop-motlon is extremely simple and inexpensive, it is adjustable and easily secured in place, one for each spindle.
It is evident that my improved roving stop-motion could be varied in construction, for difi'erent makes of spinning frames or the like, within the scope" of the appended claims. 7
