MAX POEGE, $3., OF GLAUCI'IAU, GERMANY.
KNOT'IING APPLIANCE.
To all whom it may concern Be it known that T, MAX Ponce, J r., a citizen of the German Empire, residing at Glauchau, in Saxony, in Germany, have invented certain new and useful Improvements in Knotting Appliances, of which the following is a specification.
This invention relates to appliances for knotting or tying together threads, as for example in warp-tying machines, and its object is to provide an appliance of this kind combining the advantages of simplicity and reliable action.
The invention is illustrated in the accompanying drawing, in which Figure 1 is a front view of the apparatus, Figs. 2 and 3 being views of opposite sides thereof. Fig. 4 is a rear view, and Fig. 5 a plan view. Fig. 6 shows part of the mecha nism, to a larger scale. Figs. 7 to 13 illustrate successive stages of the tying or knotting operation.
I will first describe the tying or kotting operation with reference, more particularly, to Figs. 7 to 13.
The loop is formed with the aid of a mandrel, designated 1, which is axially movable but not rotatable in a sleeve 2, into which it can be wholly retracted. A gripper 8 is rotatable about the position occupied by the forward end of the mandrel, when the latter is advanced, and the mandrel has at its front end a book 4, movable in the direction of the axis of the mandrel and adapted to grip the threads against the front surface of the mandrel. The two threads, which lie side by side, are represented in the drawing by the single line 5, and are fed to a fork 7, lying parallel with a pair of shears 6. The direction of the threads through the fork toward the mandrel is inclined to the axis of the mandrel, as shown in Fig. 5. The inclined direction of the threads before the cutting enables the gripper 3 to clear same during part of its rotation. The gripper 3, rotating in the direction indicated by the arrow in Fig. 7, grips the threads, which are then cut by the shears, the length cut off being carried around the advanced mandrel by the gripper 3, as shown in Fig. 8. The mandrel is then partly retracted, to the position shown in Fi 9, the loop being retained on the mandrel by a lateral projection 8. This partial retraction of the mandrel brings the thread-ends held by the gripper 3 into proximity to the hook 1, which is Specification of Letters Patent.

slightly advanced, whereupon the gripper 3 lays the threads behind the nose 1 of the hook, the latter being then retracted (Fig. 10) to grip the threads against the end of the mandrel. The latter is then wholly re tracted into the sleeve 2, so that the loop slides over its front edge (Fig. 11). In or der to insure that the loop slides over the hook 4- the sleeve 2 has a projecting lip 10, as shown in Fig. 6. The threads have in the meantime been released by the gripper 8, and are held solely by the hook 1. There upon a finger 9 arranged at one side of the sleeve 2 descends and engages the threads, as shown in Fig. 12, pulling the loop over the thread-ends held by the hook l; (Fig. 12) and in the course of its further descent drawing the loop tight to make a knot (Fig. 13), the thread being then drawn out from behind the hook 4.
Figs. 1 to 6 show the mechanism for actuating the several parts described for eifecting the knotting operation.
The mandrel 1 is connected to a spring 12, tending to retract it, and is guided by means of a cross-head 13 working in a slotted arm 14 fixed to the frame. The crosshead abuts against a cam 15 which has three flat-topped steps or ridges 23, 24:, 25, and is rotated by means of a crankdnmdle 16 for the purpose of advancing the mandrel.
The gripper 3 is carried by a sleeve 18 which is eccentric to the mandrel 1 and is rotatable on a bearing 17 through which the mandrel passes. The sleeve 18 is rotated by means of elliptical gear wheels 19 and 20 and spur wheels 21, 22. During each revolution of the crank 16 the gripper 8 makes two revolutions. The eccentricity of the gripper 3 in relation to the mandrel 1 is for the purpose of securing an approach of the gripper toward the mandrel after the formation of the loop, so that at that stage there is only a short length of thread between the gripper and mandrel. The elliptical gear is arranged so that the gripper movement is rapid during the formation of the loop, but then slows down while fresh threads are brought While the thread is being gripped by the gripper 3 the crosshead 18 is on the crest of the largest ridge 23 of the cam 15, the mandrel being then wholly advanced (Fig. '7 In the course of the rotation of the cam the cross-head slides first on to the ridge 24-, allowing the mandrel to be retracted to the position shown in Fig. 9, and then on to the ridge 25.
The shank 26 of the hook 4, working in a groove in the mandrel, is connected to a spring 27, tending to retract the hook. The shank is engaged with a sliding member 23, which works in a slot in the sleeve 2 and has a projection 29 outside the sleeve 2. An arm 30 fixed to the sleeve 18 carries an abut ment 31. When the mandrel is wholly advanced the projection 29 is outside the path of the abutment 31, so that during the first and second revolutions of the sleeve 18 the abutment 31 clears the projection 29, but when the mandrel has been retracted to the position shown in Fig. 9 the abutment 31 acts on the projection 29 and temporarily advances the hook 4, for the purpose already described.
The finger 9 is actuated by the spur-wheel 21; it is pivoted to a plate 33 and has a tail engaged with a link 34, which is guided by means of a stud 35 working in a slot 36 in the plate 33. The link 34 carries a pin 37. During the preliminary stages of the knotting operation a spring 38 holds the finger 9 in the position shown in Fig. 7. Then a pin 32 on the wheel 21 wipes the pin 37 on the link 34, and the finger is depressed.
The shears 9 are actuated by a slotted cam 39 on the shaft of the wheel 21. A roller 41 mounted on one arm of a. bell-crank 40 engages the slot of this cam. The other arm of the bell crank is forked and engaged with the movable shear member 42. W'hen the roller enters the part 44 of the cam slot the movable shear member is moved toward the other member, which is fixed, and the threads are out.
