on the glove.

Patented in the German Empire on April 22, 1911.

For attaching the snap fastener tops, which are composed of the cap and eyelet, to the Glove machines are known in which the prepunching of the fabric and the introduction the eyelet sitting on a lower punch into the stuffing hole through an above the Lower punch up and down takes place needle. Here the fabric is placed between two grippers placed and held, which are adjustable for themselves

ίο are and when moving downwards together pull the fabric over the eyelet. A special pressing unit is used to press the cap on, to which the fabric provided with the eyelet must be fed by the worker operating the machine.

Machines have also become known for fastening clothes buttons which an upper punch surrounding the perforating needle works together with the latter; here, however, the lower punch takes on the button to be attached to the fabric, while push the fastening eyelet from the upper punch over the needle through the fabric and at the same time on the correspondingly designed

stamp is folded behind the edge of an opening of the button.

The subject of the invention differs from these known devices forming machine in that the upper punch pierced by the needle fabric over the seated on the needle, from Lower punch worn and centered by its central spine presses, after which needle and Upper punch are raised so that the eyelet for putting on the cap is free, the then of that again for himself, d. H. upper stamp descending without a needle on the eyelet is pressed and firmly connected to this.

With this set-up and mode of operation of the machine, the laying of the with the eyelet provided material under a special press is not necessary, rather this is spared and a handout is unnecessary for the worker. The work can be faster and cheaper than before and the machine becomes a lot simpler.

The placing of the cap on the eyelet can still be done by a known per se Gripper equipped bolt are effected in one of the machine between a Cap feeder and the lower punch accordingly moved arm is resiliently mounted.

In the drawing, FIG. 1 shows a front view, FIG. 2 a plan view, FIG. 3 shows a side view against the section according to AB of FIG. 2. In FIGS illustrated. ■

The needle α, which is used to perforate the material, is located in a longitudinal bore in the ram b, which is guided in the frame d ' standing on the machine table c.

Claims (1)

A table f , which can be moved in the frame and is provided with a forwardly open slot f _x , through which the needle passes when piercing the fabric and which enables the table to move back from the needle to behind the ram, is attached under the punch. An increase f _% provided on the surface of the table serves as a stop for the fabric. The movement of the ίο needle a, independent of the ram b, is effected by an angle lever g connected to α by a handlebar g _± and a thumb i sitting on the drive shaft h , while the ram b receives its movement through two levers k, k , which are jointly operated by one attached to the drive shaft h or, according to the execution of the drawing, by two identical thumbs /, I are set in a partial rotation, in that these thumbs act on the lever arms k _v A ₁ , which are fastened with the arms k on a shaft m, which is also the axis of rotation of the angle lever g. Another thumb η (Figs. 2 and 3) fastened to the drive shaft h mediates the back and forth movement of the table f through its action on a lever n _x mounted in the frame d . In the lower punch 0 (Fig 1 and 3) a mandrel O _{1 is} arranged axially movable, which is constantly pressed downwards by a spring O ₂ and which is under the influence of a lever j> _x moved by a thumb f (FIG. 3). On the lower punch 0, an eyelet q is brought in equal time intervals by a slide r , which grips behind the eyelet supplied by a suitable device ν and presses it over a path ^ ₁ to the lower punch 0. The position of the eyelet is then _{secured by lifting the mandrel O x} , in that the head of the same enters the eyelet. The fabric pre-punched by the needle is moved down by the upper punch on the needle and brought over the eyelet. The cap can then be placed on the eyelet by hand or also by machine. In the latter case, the device described below and not belonging to the invention can be used. At a suitable distance from the frame d , a frame s (Fig. 1 and 2) is attached to the machine table, which carries a stamp t , which is moved up and down by an angle lever u. A thumb M _{2 of} the shaft k, which actuates the short lever arm U _1, is used for this movement. The feed device w for the cap y is located under the punch t ; this is at the end of its path just under a with two resilient fingers ι and 2 (Fig. 1) equipped gripper 3, which is carried by an arm 5 swingable about the axis 4 by a bolt 6 and held by a spring 7 steadily in the upper position will. During the downward movement of the punch t , the fingers 1, 2 grasp the cap y and, under the action of the spring 7, lift it out of the 6g feed device w as soon as the punch t goes up. With the arm 5 swung towards the frame d at a suitable point in time, the cap is worn over the lower punch 0. The movements of the needle a, the ram b and the table f, as well as the reception and transfer of the cap y are carried out within one revolution of the drive shaft h for fastening a push-button upper part from the machine. The design of the thumb and the translation of the rotation of the thumb f and the oscillation of the arm 5 are set up accordingly, and the operation of the machine is as follows: If the parts of the machine are in the positions of FIGS. 1 to 3, the glove is placed on the table f over the slot f _x with the point at which the upper part of the push button is to be attached. The needle a goes down and pierces the fabric ζ (position Fig. 4); the table goes back (Fig. 5); the punch and needle are moved downwards together to such an extent that the needle enters the eyelet _{in place of the mandrel O 1.} This is followed by a downward movement of the punch b, the fabric ζ being slipped over the eyelet q ; then the punch and needle go upwards after the mandrel O _{1 has} entered the eyelet shortly beforehand (position FIG. 7). An oscillation of the arm 5 now takes place, the gripper of which has previously received a cap y ; this reaches over the eyelet and fabric (position Fig. 8) and is pressed by another short downward movement of the punch δ onto the bolt 6 over the eyelet, so that the edge of the latter folds into the inwardly widened cavity of the cap. With the decline of the punch b , the spring 7 also lifts the bolt 6, the resilient fingers ι and 2 being pulled off the fixed cap. The person operating the machine therefore only has to put the glove on the table at the appropriate point in time, after which the fastening of the upper parts of the push-button takes place automatically in the manner described. Godfather ν τ claim: Machine for fastening the snap fastener tops consisting of cap and eyelet on the glove, in which the pre-perforation of the fabric placed on a table and the introduction of the eyelet on a lower punch into the fabric hole one above the lower stamp up and down moved needle working together with the upper punch, characterized in that the upper punch (b) passes the material (z) perforated by the needle (a ) over the material (z) sitting on the needle, carried by the lower punch (o) and its central mandrel (O ₁ ) presses centered eyelet (q) , after which the needle and upper punch are raised, the cap (y) is placed on the eyelet without changing the position of the fabric and then pressed on by the upper punch to connect with the eyelet.
