STOP-MOTION FOR SPINNING-JENNIES.
SPECIFICATION forming part of Letters Patent No. 499,280, dated June 13, 1893.
' Application filed November 8, 1892. Serial No. 451,320. (No modeli) spinning frame and connected by a cord which passes through suitable .devices and is connected with a spring to a belt shipper; when the machine is in operation the lever is'in a vertical position and leaning against thestrand or cord spun or being spun and is held in that vertical position by the cord unless the cord breaksin which case the lever is then pulled down and the belt is shipped from the tight pulley to the loose pulley, thus stopping the machine.
My invention consists in an improved lever composed of three essential parts, namely, a main lever rod, a tubular piece or sleeve which fits snuglyover the main rod and a spring which is inserted in the tubular portion and keeps it at the required height above the cord or strand being spun. The tubular portion is provided with two vertical slots and a pin passing transversely through said slots and through the main rod withinsecurely holds together the main rod,tubular portion and the spring within it and prevents the spring from "pressing the tubular portion of the lever 01f the main rod. The slots in the tubular portion of the lever are of sufficient length to allow the operative to press down the tubular portion of the lever until it passes under the cord or strand being spun and up on the opposite side thereof. The lever will spring up above the strand or cord on the opposite side when the hand is removed. The lever now in use is one solid rod or piece. When the cord or strand being spun breaks the lever is drawn down as above stated, the strand is tied together and it is then necessary for the operative to hold up the cord or strand with one hand while he passes the lever rod under and to the opposite side of it. It requires time and two hands to do this and the cord often cuts or burns the fingers of the operative. It is to obviate these difficulties that I have invented my improvement.
- In the accompanying drawingswhich form a part-of this specification, Figure 1,'represents a section of a spinning frame with a lever secured thereto which embodies my improvement, the lever being in position and held upright by the thread or strand as when the machine is in operation. vation of the lever containing my improvementthe dotted lines showing the position assumed by the lever when the thread breaks and the method of placing the lever back into position after the thread is tied. Fig. 3
is a detail view of the belt shifter; and Fig. t
is a face view of a spinning jenny with my improvement applied. I

The belt shifter Z is pivoted at Z on the bar s and is pulled in one direction by' the'spring n attached to said shifter below the pivot and to the hookscrew 0'-' passed through the nut p-. The cord -h is fastened to the belt shifter and .is passed over the pulley k on the bracket i and the pulley k on the bracket'i and its end is fastened to the eye hf on vthe main rod B.
A represents part of the frame of a spinning jenny. arepresents the cord or transversely through the said slots F and through the main lever rod B within the said tubular portion 0 securely holds the parts together. The part 0 may be pressed down over the main rod B until the tops of the slots F come in contact with the pin E and when the part 0 is released the springD within the tubular portion 0 expands and throws the tubular portion 0 upward until the bottoms of the slots F reach the pin E. When the machine is in operation, spinning the thread or twine a-, the lever projects above the Fig. 2 is an elethread a, the thread a holding it in itsvertical position as shown in the figures.

\Vhen the thread or strand breaks the lever is drawn down by cord has shown in Figs. 3 and 4t and following the are --c takes the position shown by dotted lines cin Fig. 2. Vhen the thread or strand is tied the operative presses the tubular portion 0 of the lever down over the main portion B until the top and bottom of the tubular portion arrive at the positions shown by dotted lines bin Fig. 2 in which position the top of the tubular portion of the lever is lower than the thread or strand a and may be passed under the same and to the opposite side thereof and the operator then withdrawing his hand the spring D presses the tubular portion 0 up above the strand a as shown, in the drawings and the tension on the cord --h holds the lever in contact with the strand a, and keeps the cord h taut and thereby holds the belt shifter in the position shown in Fig. 3, that is, on the fixed pulley. As soon as the thread abreaks the lever swings down into the position shown in dotted lines in Fig. 2, permitting the spring --n to throw the upper end of the belt shifter to the right as shown in Fig. 3 so as to throw the belt off.
I claim- 1. In a stop motion for a spinning jenny, the combination with a belt shipping mechanism, of a cord connected therewith, a swinging lever B to which the other end of the cord is fastened, the tubular portion or sleeve C provided with slots --F-, the pin -E-, and the spring D in the sleeve 0, substantially as and for the purposes specified.
