STOP MECHANISM FOR SPOOL-CARRIERS.

SPECIFICATION forming part of Letters Patent No. 504,796, dated September 12, 1893.

Application filed April 1J 1893. Serial No. 468,629- (No model.)

.To all whom it may concern.-

Beit known that I, ADOLPH BAYLEE, a resident of the cit-y, county, and State of New York, have invented an Improvement in Stop Mechanism for Spool-Carriers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part hereof, wherein- Figure l is a side view of a spool carrier embodying my invention. Fig. 2 is a back view of the same, that is, looking in the direction of the arrow, Fig. l. Fig. 3 is a side view, with parts broken away, and in section, to better show other parts ot' my improved stop mechanism. Fig. lis a sectional detail of the tension drum and parts connected thereto.

This invention relates to an improved stop mechanism for spool-carriers of braiding and other machines, and consists in the arrangement and combination ot' parts hereinafter described and claimed.

The object of my invention is to provide a spool-carrier with mechanism which Will automatically stop the machine when the thread of a carrier is broken, thereby preventing much delay and imperfections in the finished material.

In the drawings the letter A represents a spool, mounted on a suitable support A and carrying the thread to be formed into a braid. This thread is conveyed around a suitable guide a (as shown in Fig. 1.), and through an eye b, or otherwise to an eye in the slide c, whence it may be carried through an eye d to the point of braiding in the machine. The slide c is connected, as by string e, to a drum B, and is held under tension by a coiled spring in said drum, which spring may be regulated by a tension device, as shown at Qc. Connected to the drum B is a cam f against which bears the arm l of a lever, O; the arm 2 thereof being adapted to contact with a pin g carried within the hollow shank D of the spool-carrier. This pin g is adapted to protrude from the bottom of the shank D when the pin is in its lowest position as shown by dotted lines in Fig. 3.

E designates a latch which controls the output of the spool A, and is operated by the slide c.

The operation of my improved stop mechanism is as follows: After the thread is conveyed from the carrier to point of braiding sition with the lower end thereof drawn into the shank D, as shown in full lines in Fig. 3, but the instant the thread is broken the slide c is released and the spring in the drum unwinds, causing said drum to turn, bringing the lowest part of the cam fin contact with the arm l, of the lever C lowering the pin g, so that the end thereof will protrude from the bottom of the shank of the carrier, as sho-Wn in dotted lines in Fig. 3. This pin when lowered arrives in the plane of a suit.- able lever (not shown), which operates to stop the machine in Well known ways, it being understood that the shank D is held on a revolving or reciprocating carrier frame.

It is obvious that I might employ any suitable tension mechanism in connection with the stop device, but I have found the one shown reliable and eective.

Having described my invention, what I claim isl. In a stop mechanism for spool-carriers, the combination of the drum B for applying tension to the thread, cam f operated by said drum, pin c, and means for connecting said cam and pin, substantially as and for the purposes specified.

2. The combination of the tension drum B, camfcarried by said drum, pin g, and lever C for operating said pin, all arranged so that when tension is relieved from the drum B, the pin g will be released, substantially as described and for the purposes specified.

3. A vertically sliding pin, a tension slide c for the thread, a support for a spool, a tension drum connected with said tension slide, and mechanism connecting said drum with said pin, all combined and arranged to hold the pin raised whenever the drum is under tension, and to allow said pin to drop when the drum is not under tension, as specified.
