MACHINE FOR FORMING TASSEL-BUNCHES.

SPECIFICATION forming part of Letters Patent No. 467,435, dated January 19, 1892.

Application filed April 21, 1891. Serial No. 389,840; (No model.)

To all whom it may concern.-

Be it known that we, GEORGE REHFUSS, JOHN GEORGE REHFUSS, and MARTIN O. REH- FUSS, citizens of the United States, and residents of Philadelphia, Pennsylvania,have invented certain Improvements in Machines for Forming Tassel-Bunches, of which thefollowing is a specification.

The object of our invention is to construct a machine for automatically winding tasselbunches consisting of a longitudinal skein or hank of chenille or other yarn having the end of the yarn suitably secured to prevent the unwinding of the said hank or skein, our ma chine being especially adapted for winding that form of tassel-bunch in which there are cross-windings at or about the center of; the skein or at different points on said skein, in order to hold the longitudinal wrappings in place. This object we attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure 1 is a view of atassel-bunch such as produced upon the machine. Fig. 2 is a side view of the machine, parts being "shown in section. Fig. 3 is a plan view of the same, and Figs. 4, 5, 6, and 7 are detached views of parts of the machine.

A is the bed-plate of the machine, and B is a winding-shaft free to turn in suitable bearings on said bed-plate and adapted to be connected to the drivingshaft B by means of a clutch D, which in the present instance is similar to that forming the subject of Letters Patent No. 362,997, dated May 17, 1887. The driving-shaft B has a worm a, (see dotted lines, Fig. 2,) which engages with a wormwheel a on a cam-shaft F, arranged transversely to the shaft 13' and having a series of cams G, H, I, J, and M. The cam G acts upon an anti-friction roller G, carried by an arm on a rock-shaft G which is free to turn in a suitable bearing G on the bed of the machine, and has another arm G for operating the clutch D, so that while the driving-shaft B rotates continuously intermittent movements of rotation are imparted to the winding-shaft l3. Said shaft'B has at its outer end a winding-head B and in suitable arms or standards 1), near each end of said winding-head, are

mounted shafts B which terminate at their inner ends in winding-hooks B one of which carries an inwardly-projecting plate B ex by a transverse shaft H which is free to turn in bearings in the arms I), this shaft having near each end a toothed segment l-l which meshes with a pinion H on the winding hookshaft The cam I acts upon an anti-friction rolleron an arm I, which projects from a rock-shaft 1 hung between centers at one end of the machine, the outer end of said arm I carrying an eye-pointed needle 1 as shown in Fig. 2. The cam J acts upon an anti-friction roller on an arm J, which is connected by a link J 2 to a lever J on a rock-shaft J free to turn in depending hangers J beneath the bed A, said lever J engaging with another lever J likewise hung to a rock-shaft J beneath the bed, one arm of said lever J and an arm J 8 at the other end of said rock-shaft J carrying a rock-shaft J to which are secured a series of hooked fingers J The rock-shaft J carries an arm J, which acts upon one arm of a lever J the other arm thereof acting upon a lug on an arm J hung to a stud on the winding-head B said arm J acting upon a lever J one arm of which operates, in conjunction with the plate B, to form a retainer for the loose end of the thread, as described hereinafter, said lever J being acted upon by a spri1igJ ,Fig. 2, which tends to move it into engagement with the plate B The cam M acts on an anti-friction roller carried by a swinging lever M, which is connected by a link M to a sliding head M ,car- 5 rying a hook M, and adjacent to and guided on this sliding hook is a knife-blade M as shown in Figs. 2, 5, and 6. The blade M has a pin M, projecting through a slot M in the hook M and head M and when the hook M is projected this pin M comes into contact with a stop M on one of the bearings M" for the hook, and is thereby retracted in relation to the hook, as shown in Fig. 6; but as thehook nears the limit of its backward movement the rear end of the knife comes into contact with the bearing M or other equivalent stop, and the knife is thereby projected again, as shown in Figs. 2 and 5.

In the operation of the machine the loose end of the yarn is in the first instance confined between the plate 13 and lever J and passes thence through the eye of the needle, which is held normally in the elevated position shown in Fig. 2. The clutch D being put in operation, a rotary movement is imparted to the winding-head B and the yarn is wound upon the winding-hooks B for the desired number of turns. The clutch D is then thrown out of action, and the winding hook-shafts B are rotated by the mechanism receiving its movement from the cam H. This has the effect of forming the transverse wrappings around the bunch, such wrappings being at the center of the bunch, owing to the fact that during such transverse winding operation the yarn has a bearing upon the inner end of the internally-projecting plate B Vhen the central wrapping has been completed, the needle descends through the center of the bunch, and thus carries the yarn through the same from one side to the other, so as to retain the end of the central wrapping. The hook M then advances and catches the loop of thread from the needle, and on the retraction of the hook the knife M is projected so as to cut the yarn, the needle then rising through the bunch. Before the central wrapping was formed on the skein, however, the rock-shaft J 4 had a slight movement imparted to it sufficient to carry the lever J beyond the point where said central wrapping -was to be formed, and on the rise of the needle the rock-shaft J 4 is moved in the opposite direction, so as to move the hooked arms J inward over the bunch, the lever J resting against the central wrapping of the bunch under the tension of the spring J After the hooks J have been moved inward so far as to engage with the bunch the movement of the rock-shaft J 4 is reversed and the hooked arms move outward, so as to pull the bunch from the winding-hooks B and permit it to drop from the machine, and at the same time the lever J swinging inward, catches the loose end of yarn hanging from the needle I and confines the same against the plate B so that the parts are in position for a repetition of the operation. WVhere there are to be two or more cross-wrappings on the skein, the numberof needles and co-operatin g parts will be increased accordingly, the yarn from all of the needles forming the skein and the yarn from each needle forming a cross-wrappin g in line with said needle. In cases where a series 7. of turns to form a cross-wrapping is not required the means for rotating the hooks 13' may be dispensed with.

Having thus described our invention, we claim and desire to secure by Letters Patent 1. In a t-assel-bunch-forming machine, the rotating winding-head having winding-hooks rotating on said head in a direction at right angles to its own rotation, and means for rotating said winding head and hooks, substantially as specified.

2.
