Description

The essence of the invention lies in the design of the transmission mechanism of the device for measuring the length of the film.

In FIG. 1 shows a top view of the device with a partially opened lid; FIG. 2-vertical section of the device; FIG. 3-view of the transmission from above; FIG. 4-vertical section of it.

The device is a counter driven by movement of a film drawn through a toothed drum 4 (Fig. 1). On the axis 5 of this drum (phi 2) there is a screw thread that engages inside the oil sump with a screw wheel b on axis 7 (Fig. 4). The rotation of this axis through gears S and fO with the pawl 9 (Fig. 3) is transmitted to the axis // with the disk J2 equipped with a cam / 5. A digital disk J4 is mounted on the upper end of the axis //. It has numbers from A to P.

When the disk f2 is rotated, the cam projection / J breaks the short shoulder of the put-, chaga / 6 and causes it to turn on the axis / 7. At the other end of the lever / b there is a pawl / I which npVj turn the lever / 5 grabs the teeth of the teeth 22 placed under the disk 2 on

.. axis 2J, and rotates it to the turn, as the gear 22 has, ten

teeth Together with the gear 22, the axle 2 will also turn down. and since the digital disk 23 is mounted on the 2G axis, it turns into V, o turn to and the window on the lid 2 is set as follows; numeral. As the disk 72 rotates further, the lever's short arm / (wrists tightly to the cam} 3 primer caps down to its center, spins back and forth) on the axle 7 of the spring 25, and the doggie S grabs the next tooth Zubchatki 22, again turns the axis 2G on Vio. SopOTa and-t. d.

On axis 2, the nazendisk 20 (ft. 3) ,. having one big one and go r-cini,:. x. recesses; when rotated and drive 20 on. Vio turn, the protrusion 26 of the large recess meets the short arm of the lever 27 (similar to the lever b) and instructs it to turn on the axis 29. after that the short arm of the lever .aclst into the small recess on the disk 20, which means that the latter takes a stable position until the disk 12 will not make a full turn. After that described. The interaction of the cam / .V and the lever 16 is repeated, the disk 20 is rotated another Vio turn and the end of the short lever-lever 27 falls into the next small depression. 3 tog torque (when the disk / 2 makes ten, revolutions end, short arm

This 27 again falls into a large recess on the disk 20 and with the help of the spring 2L turns on the axis 29. With this, the dog 30 grabs the teeth of the teeth 31 and forces it together with the pig 32. and the digital disk 33 turns on / 10 turn and so on. d.I

 On the axis 52 a disk - / - with a recess is inserted, by means of which the lever 59, which sits on the axis 5 /, is actuated. Similar to the above, a lever 59 with an axle 62, acting on the gear 60, which sits on the axis 63. —the carrier digital disk 34; Thus, with a full turn of the disk 34, the digital disk 33 will make ten revolutions, the digital disk 25 hundred revolutions and digital Drive 14 thousand revolutions. Gfy full turn of the digital disk 34 reading the reading will be equal to ten you cham-subway.

At the end of the measurement, all the lengths of the film are taken and the instrument is dragged away, which is achieved as follows. Pressing the lever 36 (Fig. 1) from left to right, squeezes the spring 57, while the gear 3 of the rail 3S slides to failure along the groove made in the lid 55 (Fig. 4) of the oil crankcase 3. The gear rail 38 rotates the shaft 41 and sits on disk 42 (Fig. 4). When the disk 42 is rotated, the doggie 43, with its end, falls into the recess made on the axis 11, and rotates it together with the digital one; with a suit J4. When rotating 7, the gear 10 is wrung up. Doggie Slide the teeth, thanks

which the gear wheel S remains fixed. At this moment, all four digital discs are turned and zeros stand against the windows on the flap. The discs, and 44, also rotate and take the same position, and the ends of the short arms of the levers will fall into small recesses following the large recesses.

When the lever 36 is stopped, the spring 57 opens and the rail 38 returns to its original position. When the rail 5 moves from right to left, the pinions 41 and three others, as well as the disks 4, 45, 64 and 65, rotate s in the opposite direction. JlpK this corresponding doggie 43, and so on, slides around its axes in vain.

The rollers 56 and 57 serve to guide the film, and the pressure roller prevents the tape from jumping off the drum 4.-

The subject matter of the invention.

A device for measuring the length of a film, in which, by means of a corresponding beam, the transfer of the translational movement of the tape is transformed along the rotational motion, and a number of digital discs differing in length are used to indicate the length, so that the spring arms of the spring arm are used for turning the said discs operating through the dogs on the teeth, which sit on the axes with digital discs. .-...
