SU12405A1 - Device for counting pegs when measuring with measuring tape - Google Patents

Description

Putting the first ribbon on the peg with the fastened fastener attached to the box, it is intended to achieve on the bushon tape an automatic mark of the number of pegs passed and, moreover, to obtain the corresponding indication on the dial of the counting wheels.

In the schematic drawing of FIG. 1 depicts a view adapted from below with a longitudinal section of its box; Fig. 2 is a side view of the device with the box lid removed.

A device for counting pegs with intent measuring tape consists of a box 3 with double side walls (Fig. 1, 2) fixed at the end of tape 11 (FIGS. 1, 2) forming a slot into which a paper tape 15 is inserted. Inside the box 3 is placed a plate 6 ending A prong 12, which, like a dog, can be coupled with a countable standard wheel 1, transmitting, using pin 16, tens to the counting wheel 2. At the other end of the plate 6, which is under the action of the spring 7, there is a tip 13, which serves puncture tape 15 and so

Thus, marking the punctures on the stretched tape 15, the number of pegs passed.

The belt 15 is pulled between the side walls of the box 3 by means of two wheels 4 and 5, frictionally engaging with each other and having knurling on cylindrical surfaces. The wheel 4 sits on the same axis with the counting wheel 1 and together with it receives a rotation, which is not edited further by the wheel 5, immediately adjacent to the belt 15 and moving it during rotation.

In the lower part of the side walls of the box there is a slot corresponding to slot 8 on the tip of the tape 11 and serving to put a device on the pegs, which also also enters the slot on the plate 6, which closes the slot 8 in off-line (Fig. 2).

On the counting wheels 1 and 2 there are dials with units and tens allowing to read the readings in the corresponding cut-outs of the side flap. On the box 3 with the tape 11 on the peg, the latter, when the tape 11 is tensioned, being in the slot 8, moves the plate 6,

Eotor at this compresses the spring 7 and the tip 13 on the tape 15 produces a puncture. Simultaneously with the movement of the plate 6, its prong 12 rotates the counting wheel 1 by a step of the pitch of the teeth, and a corresponding indication is established in the cut-outs of the side cover; In addition, when the counting wheel 1 is rotated, the wheel 4 also rotates, transmitting the rotation 5 to the wheel 5, which informs Lept 15 that the movement is not necessary.

The counting wheel 2 with tens receives a turn on one tooth only after wheel 1 makes one turn, which corresponds to ten relocations and plate 6, or the same number of pegs passed; the transfer from the counting wheel 1 to the wheel 2, as mentioned, is carried out by means of a pin 16. After stopping the tension of the tape 11 and removing the device from the spring-7 peg, press the plate 6 to its original position, while the tooth 12 of the plate falls behind the next tooth wheels 1, for keeping which from reverse rotation serves the pawl 14 with set screw 9.

The head 17 is intended to bring the wheels 1 and 2 to the zero position, as well as to pull the tape 15 in the side walls of the box 3.

Thus, when measuring with a measuring tape, at any moment it is possible, according to the indications of the fixture, to see the number of tapes passed, and through punctures, the film 15 may check this number; For reading out the lobes of the ribbon, blanks 10 inserted into the holes on lepte 11 can be used.

The subject of the patent.

A device for counting pegs when measuring with a measuring tape, characterized by the use of a box 3 with a reinforced pa end of the tape 11, having double side walls, forming a slot for passing the paper tape and provided with a slot corresponding to the cut on the tape for putting it on the pegs in which the box is movable, a plate 6, which is partially closed in the non-working position, is under the action of a spring 7 and is provided at one end with a tooth 12, which engages with a ratchet counting wheel 1 transmitting tens to the counting Olesen 2 and the other end having a tip 13 which serves, when introduced into the slots and kolyshka tensioned or drawn tape ribbon to puncture, to which are movable wheels 4 and 5 are knurled.
