T 0 all whom it may concern:

Be it known that I, EMIL KOLLMAR, citizen of the German Empire, and resident of Pforzheim, in the Grand Duchy of Baden, with the post-oflice address Schwarzwaldstrasse 22, Germany, have invented new and useful Improvements in Method of and Apparatus for Afiixing Objects on Cards or like Supports, of which the following is a specification.

This invention relates to a method of and apparatus for affixing objects, more particularly trinkets or jewely, to cards or like supports by means of a thread, both ends of which after they have been passed through the support are connected on the other side thereof by knotting them together. Hitherto this affixing and knotting has been performed by hand and has involved much time, labor and cost. By this invention the operation is conducted in a purely mechanical mamier by means of an apparatus similar to a sewing machine'which is constructed in a manner adapted for the work in question.

The method and the mode in which it may be applied by the apparatus are set forth in the following description and are illustrated in the drawings, which show one example of the invention.

Figure 1 is a fragmentary elevation partly in section of some of the knot forming elements.

Fig. 2 is a view similar to that shown in Fig. 1 showing the elements in the second stage of the operation. 7

Fig. 12 shows the top plan view of some of the elements of Fig. 11.

Fi 13 is a view similar to that shown in Fig. 1 showing the elements in the ninth stage of the operation.

Fig. 1 1 is a view similar to that shown in Fig. 1 showing the elements in the tenth stage of the operation.

Fig. 15 is a view similar to that shown in Fig. 1 showing the elements in the eleventh stage of the operation.

Fig. 16 is a view similar to that shown in Fig. 1 showing the elements in the final Fig. 17 shows an elevation of the loop forming elements.

Fig. 18 shows a view similar to Fig. 17 but partly in section.

Fig. 19 is a plan of the assembled working parts.

Fig. 20 is a side elevation of Fig. 19 looking in the direction of arrow A.

Fig. 21 is an end elevation of Fig. 19 lookin in the direction of arrow B.

, Fig. 22 is a diagrammatic elevation of the whole machine.

The machine, by means of which the method is operated, resembles in the example given a sewing machine. Fig. 22 shows that the machine comprises a plate 1 above which there stands a needle arm 2 of the form usual in a sewing machine; the head 3 of this arm has the usual two vertical guides, one of which is for the needle holder 4 and the other for the presser, not here shown. WVith the presser there may be combined, if necessary, a forked or similarly shaped part which serves to move mechanically to and fro the object to be affixed to the support, that is to say to hold the object first to the left and then to the right of the needle. This to and fro movement of the object may obviously be performed by hand and is essential in order that the needle during its two passages through the card may pass by the object once on the left hand side and once on the right hand side.

Below the plate 1 are the tools which cooperate with the needle to carry out the method. The various journals, shafts, couplings and the like for these auxiliary parts are .not shown on the drawing, but in Fig.

- 22the box 5 shown in dotted lines contains having a free end as shown in Fig. 1, passes through the card support 16 as shown in Fig.

'1, the card lyingon the plate 17 of the machine so that the thread 18 can be engaged by the gripper 8.

The needle thereupon rises, as shown in Fig. 2, while the gripper 8, which is caused to pass outwardly around the jaws of the pincers7, presses the thread 18 against the under surface of the plate 1? and so holds it. The object to be afiixed, for instance a small tube 19, is now moved sidewise from the position shown in Fig. 2 to that shown in Fig. 3, so that when the needle next moves 7 downward, which is the position in Fig. 3,

the needle 6 lays the thread 18 around the object '19. In this second descent of the needle, the gripper 9 comes into action, engages the thread and clamps it on the gripper-8 when the needle rises again as shown in Fig. 4. At the point 00, indicated in Fig.

4, the lowermost thread is cut by knife 10 (shownin Fig. .5) cooperating with the stationary cutter 11 with the result that theend 18 of the thread is withdrawn fromthe card 16 but remainsthreaded in the needle'6. As soon'as' the parts have arrived in the position indicated in Fig. 5 the pincers 7 begin to turn about their axis through 360. Figs. 7 l and 8 show the pincers in side elevation and in plan'after rotation through 180, while Figs. 9 and 10 show in side elevation and in plan the pincers after they haveperformed the complete revolution of 360. Before the revolution is finished the pincers open so that after the 360 have been completedthe two threads'are in or between the jaws of the pincers as shown 'in Figs. 9 and 10. Thereupon theepincers close insuch a man ner that the lower jaw moves against the upper and at the'same time the pin 12 presses forward in such a manner that it lies on the upper jaw of the pincers between this and the loop of the thread. The pincers 7 now turn as indicated in Fig. 11 backward through 360 into their original'position and 'of the pincers.

thereby screw themselves out of the knot 20. The pin 12 retains its place and holds the knot in its position after the pincers have been withdrawn. At the same time the grippers 8 and 9 liberate the ends of the thread so that these can be drawn from the closed pincers, through the knot, since, as already stated, the two threads are held in the grip I When the pincers have turned through about 27 0 the withdrawing hook 13 rises as indicated in Figs. 11 and 12, pushes itself between the pincers and the knot into the latter and draws the free ends of the thread wholly from the knot as shown in Fig. 12, so thatthe position becomes that shown in Fig. 13. The pincers now move slightly downward as shown in Fig. l'in order to allow room for the stretching fork 14, which now embraces the ends of the thread between the pincers and the knot 20. The pin 12 is still within the knot 20. The fork 14 is for the purpose of drawing away the knot 20. For this purpose three movements are necessary. In the first place the pincers must move downward, secondly the stretching fork must move upward and finally the pin 12 must be withdrawn from the knot.

In Fig. 15 the parts are shown in the position which they have after the further downward movement of the pincers and the rise of the fork 14, the pin 12 which has been withdrawn from the knot not being visible. While the parts are in this position the knife 15 moves forward and cuts the stretched ends of the thread as indicated in Fig. 16, whereupon the tools return to their normal position and the pincers open so that the cut ends 20 of the thread leave the machine,

for instance they maybe blown away as waste by the device 21 indicated in Fig. 19.

Fig. 19 shows the relative positions of the tools as seen from above. There is the shaft 22 for operating the withdrawing hook 13, the shaft 23 which moves the stretching fork 14,the knives 10, 11 and 15, thetwo grippers 8, 9, the pincers 7, the pin 12 and the axis of the needle 6.

The plate 1, as shown in 19, has an opening 24: forthe sewing machine arm and also a larger opening in which may be fitted besides the sewing plate 17, three cover plates with dove-tail guides.

Fig. 20 shows the relative positions of the tools in side elevation, the shaft 25 is for the knife 10. Fig. 21 shows the device for operating the grippers 8and .9. V

The pincers 7 are shown separately in Figs. 17 and 18. Obviously't-heir form may be varied so long as they fulfilthe desired purpose. -As already stated the lower jaw 26 moves against the upper jaw 27, this movement in'the example shown in Figs. 17

and 18 being produced by a pin 28 which engages the body 7 of the pincers by means of forks, with which body the jaw 26 is connected by the ends of the screw 31 or otherwise. The downward movement of the pin 28 is produced by the pressure of a lever 32.

When this pressure ceases the spring 33 closes the pincers. The upper jaw 27 is connected at 31 with an extension 30 which is guided axially in the body 7 of the pincers and engages at its lower end with the fork 29 of a pin 35. The downward movement of this pin 35 against the spring 33 is produced by the pressure of the lever 37 as in the case of pin 28. If therefore the pincers are to be opened the body 7 moves downward'with the jaw 26 in the guide 34:, as shown in Fig. 18, while the pin 30 with the jaw 27 remains stationary. When the pincers are to descend as a whole both the levers 32, 37 come into operation.

The rotation of the pincers around their longitudinal axis may be produced in several ways, such as by a rack and pinion or toothed segment; the necessary parts are not shown in the drawings.

As shown in Figs. 17-19 the jaws of the pincers are hollowed out in such a manner that the needle 6 can descend and ascend without hindrance.

As the invention can be applied by many forms of apparatus it is not necessary to mention many auxiliary devices which may be used. For instance there may be tools or other devices for facilitating the operation such as stops or the like against which the card supports may be pressed for accurately determining the distance between the objects aflixed. The machine may be driven by a motor and in such a manner that the motor is automatically cut ofi' when the object has been duly aflixed.

Now what I claim and desire to secure by Letters Patent is the following:

1. In an apparatus of the character described, the combination of a needle carrying a thread adapted, in its reciprocations, to lay the thread around an object, grippers to hold said thread, movable pincer jaws to loop said thread, means to pass the loosened ends through the loop thus formed and means to draw the knot taut.

2. In an apparatus of the character described, the combination of a needle carrying a thread, a gripper to hold the thread during the reciprocation of the needle, movable pincer jaws to engage and loop the thread, a second gripper to hold the thread during the reciprocation of the needle, means to sever the thread and a hook to withdraw the severed ends through said loop and means to tighten the knot thus formed.

3. In an apparatus of the character described, the combination of a reciprocating needle carrying a thread, a gripper adapted to engage and hold the end of said thread on the downward reciprocation of the needle, movable pincer jaws to loop said thread, a pin to hold said loop in an open position, a withdrawing hook to pull the released ends through the said loop, and a stretching fork to tighten and press the knot formed tightly against the underside of a card.

That I claim the foregoing as my invention, I have signed my name in presence of two witnesses, this fifth day of November, A. D. 1915.
