Description

The present invention relates to devices for determining the diameter and number of yarn. This device consists of a box in which an accumulator battery is located, which excites an electromagnet that moves a movable plate, hingedly connected with an arrow, giving directly on the caliper an indication of the diameter and number of the measured yarn, clamped during its testing by spring-loaded sliders of two side columns.

In the schematic drawing of FIG. 1 shows a front view of an instrument for determining the diameter and number of a yarn; FIG. 2-side view.

The said device for determining the diameter and number of the yarn is mounted on a brass plate 2, which serves as the base of the entire device and is placed on the wooden box 1 in which the battery is located. The latter, as required, serves to excite an electromagnet having a horseshoe-shaped shape and fixed on the middle column 24. On the latter there are two plates between which a thread is placed during the test. The upper plate-17 movable moves along the guides of the column 24. The armature of the electromagnet is a metal strip 20 attached to the plate 17 and pivotally connected to the upper end with levers 26,27 (Fig. 1), transmitting the movement of the core 20 when the circuit is closed by a two shoulder. lever 25, the end of which is equipped with an arrow 12, which gives these or other indications on the scale. For clamping the yarn on both sides of the middle column 24, two columns 23 are mounted, each carrying a spring-loaded slider 16 sliding in the slots of the column 23, which slider 16 tends to press against the fixed part 5 of the column 24 and from the latter at a certain height using a spring-loaded latch 21 (Fig. 2).

The measurement process is as follows. A piece of the tested yarn is taken in the hand and, slightly natnudu, is inserted into the slit AB (Fig. 1), while pressing with the fingers on the head of the movably mounted rods 15, which with their ends squeeze the latches 21, releasing the spring-loaded sliders 16 5 columns 24, clamping the thread (Fig. 2). At the same time, the weights put pressure on the thread under test, pulling it on a fixed plate; then press the electric button 4 and see the result of the readings of the arrow 12 on the scale. To release the thread after testing, press the buttons 3, 3 (fkg. 1 and 2)

bifold arms 13,14, raising the sliders 16 to their initial position, and removing the thread, thereby completing the measurement process, which takes several seconds. In addition to measuring the diameter and the number of yarns, the device can give a consistent change in yarn thickness, i.e. its uniformity. To do this, the test thread only needs to be pulled at a low speed between the measuring plates.

Subject invention

1. A device for determining the diameter and yarn number, consisting of two plates between which a yarn is placed, of which one plate is stationary and the other is mobile and pivotally connected to an arrow giving indications on a scale that differs from the movable plate 17 is applied an electromagnet mounted on column 24 to an excitable, as required, by means of a rechargeable battery placed in box 1, serving as the basis for the device, which plate 17 is attached to the metal strip 20, which is Orem electromagnet and acting via the levers 26 and 27 by closing the circuit at the arrow 12.

2. At the device, - indicated in item 1, the use of two columns 23 for clamping the yarn when testing it, located on both sides of the column 24 and carrying each heated slider 16 sliding in the slotted column and held at a certain height from fixed plate 5 column 24 using a spring-loaded latch 21, flip, in order to clamp the yarn, through a movably mounted rod 15.
