Description

The invention relates to a device for basting loops and buttons when sewing clothes, which is provided with an electromagnet for actuating punching needles.

In the proposed tool, the magnet of the electromagnet serves simultaneously for raising the frame with needles and for lowering the pressure plate.

In FIG. G depicts the device in a vertical longitudinal section; FIG. 2 is the same in a vertical cross section; FIG. 3-side view of the bracket; FIG. 4 is the same in longitudinal section and FIG. 5-7 parts and accessories.

The fixture consists of a hollow column / on which electromagnet 2 is placed, inside which there are core (measles) 3 and spring 4, Anchor 3 is connected with gear rack 5, its lower end passing into a cylindrical cup in which the spring 7 is placed. 5 is coupled with gears 5 and P, with gear 8 sitting on the JO shaft passing through the cast arm (sleeve) 7 / in which there are sleeves 72. On the same shaft / O there are two eccentrics fixed / 5 above which there is frame J4 with rollers 75 (Fig. 4). The frame M of the channel section has in the upper shelf

a longitudinal section in which the needles (7) are reinforced, passing through the holes J8 in the strip / P, placed in the guide grooves 20.

Under the upper rail 7P there is an adjusting nut 27 on the screw 22, the other end of which is bent for an abutment (FIG. 3).

Above the bracket 77 there is a bracket 23 with tides 24, in which there are sockets (parallels) 25 for the frame 26, to the lower part of which a bar 27 is screwed with openings coinciding with the holes 75 in the bar 19, In the middle of the frame 26 there is a rack bar 28 and a gear 2P gear, sitting on the shaft 30. At the bottom of the column 7 there is a pedal device consisting of a pedal 57 with a lever, a rod 32, springs 33 and contacts 34. On the same column 7 there is a movable chair 55 on the arm 36 and a retractable stereo gin 57 with a slit 38. The rod is secured with a screw ZR; the chair has a lifting screw 40.

The clothes are placed on the bracket 77, brought up to the stop screw 22 and rolled onto the extreme needle 77, which is higher than the others. With the other hand, the clothes are pulled and leveled; then the pedal 57 is pressed to move the rod 52 and the contacts 34 are turned on,

smopb 5 is drawn into electromagnet 2; gear rack 5, lifting up, rotates the gears and P and the shafts JO and 30, which causes the eccentrics / 5 to raise the frame M with the needles / 7, which pierce the material pressed by the bar 27 that is lowered from the shaft 30. strap / r.

After releasing the pedal 5 / the spring 33 takes away the rod 52, the contacts 34 are disconnected and the electromagnet 2 ceases to act on the bark 3, which causes the latter to fall down under the action of the spring 4.

The subject matter of the invention

Claims (2)

1. Device for basting buttonholes and buttons when sewing clothes with using an electromagnet to actuate the hole-piercing needles, characterized in that the armature 5 of the electromagnet serves simultaneously to lift the frame with the needles 77, and to lower it and to lower the pressure plate 27 | 2. The form of the device according to claim 1, characterized by the use of a toothed rack connected to the core of 3 electromagnets and with shafts 7 (9 t30, of which the JO shaft rotates eccentrics 75, lift, periodically, the lower frame J4 sec needles 77, and the shaft 30 — to bring the upper clamping bar 27.3 in motion. In the device according to points 1 and 2, use pedal 57, which serves to turn on the electromagnet using switches 52-55 and contacts 34.
