Description

The present invention relates to the construction of an automatic rolling machine for a perforated telegraph tape designed for servicing transmitters of primarily American and English type.

The design according to the invention allows the strip to roll out of the transmitter, with a self-gripping tape with constant tension and stopping the transmitter itself when the tape is finished or broken.

In the drawing fng. 1 shows a machine on the side with a partial longitudinal section, and FIG. 2 is a cross-section of it according to the AB of FIG. one.

On a wooden (or any other) box / there is a bracket 2 with a horizontal bearing in its upper part. The axis 5 in the right-hand part ends with a friction disk, against which roller 4, having a rubber rim, is pressed. The roller 4 can move along the axis 5, rotating with it, and fixed in any place by a stop screw. The J axis with one end (left in FIG. 1) lies in the bearing 6u mounted on the box, and the other end, which has a worm to the serrated 7 with inclined teeth, is mounted in the bearing on the transmitter box and. interlocks with the gear located at an angle of 90 ° on the axis of the transmitter, in part between the gearbox and the head of the transmitter (in the case of the American transmitter, while in the English transmitter the gear is mounted on the free end of the engine axis).

In the left part of the axis 3 is fixed, the disk 8, on the end of the same axis there is a thread and a nut 9, which is reinforced in position on the thread with a locking screw in the outer side of the axis. Between the disk 5, on the one hand, and the JO washer, on the other hand, the base of the coil 72 is clamped, which is a disk ground on both sides with the cheek / 5 of the coil attached to it. Thus, the coil J2, with the exception of the outer removable cheek 7, is fixed with some friction on the axis-5, and the amount of friction is regulated by the pressure of the flat spring washer / 5 by means of the nut I and the outer cheek J4 of the pipe / 2 is provided with a cylindrical part, which slides onto the drum of the coil base and is held on to it by friction. The tape is wound on the cylindrical part of the outer cheek and is easily removed along with the cheek by simply pulling it off. Cylindrical part of coil

The shot is covered on the most part of its circumference by a flexible infinite tape lying on a series of rollers 77., 18, partly fixed on the arc 16, and the part being in the box /. When the coil / 2 is rotated, the tape is grabbed by it and freely rolls on the rollers which carry it. The perforated tape, being directed by the operator's hand (or with full automation by the guide channel), between the cylindrical part of the coil and the tape, is caught between them as they move and winds onto the reel. During winding, the diameter of the tape disk winding onto the coil increases all the time and the flexible tape is continuously fed out of the crate, overcoming the resistance of the two rollers 19 that are fixed at the ends of the levers turning on their axles and pulled by the springs to a position in which The tape is in the box.

When moving from the head of the ranmitter to the reel, the tape passes between two rollers 20 and 2 pressed against each other. The roller 2 is fixed on the axis located in the rack 22, and the roller 21 is fixed on the end of the lever 25, which can rotate on the axis fixed in the rack. When the tape is between the rollers, it due to its thickness, and during movement and due to tension, lifts the roller 2 /, and together q them and the upper arm of the lever 25, caused its lower long arm to press on the contact 24 and to close it. Terminal 24 is connected in parallel with the switch of the electric motor of the transmitter,. which in this way can be switched on either by hand-off switch or automatically by tape. The lever 25 is provided with a hook, when pressed, when the roller 21 rises and the contact 24 closes, which is usually necessary to produce when pulling the tape between the rollers. The upper roller 21 has ribs that prevent lateral displacement of the tape.

The machine is operated as follows. The beginning of the tape is inserted into the transmitter head, then the hook of the lever 25 is pressed, the transmitter motor is turned on and the tape started, the tape is passed by hand or by a special groove between the rollers 20 and 21, after which the hook is released and the transmitter continues to work. The tape, continuing to move, falls between the cylindrical part of the coil and the flexible tape and is gripped by them.

The roller 4 is set at a certain constant, for a given transmitter, a position relative to the disk at which the winding speed of the tape on the coil somewhat exceeds the speed at which the tape enters from the transmitter. With further winding, the speed of the tape on the circumference of the coil increases, but the tape coming out of the transmitter at a constant speed brakes the coil, causing it to turn on axis 5.

The BOX / can be positioned under the base of the transmitter, and in the case of the American transmitter, the machine is placed on the base of the transmitter in the front left part, at the switch-transmitter switch that is placed on the side of the transmitter base. With the English transmitter, the width of the box will be somewhat larger than the width of the transmitter and the latter will be located on the box next to the machine gun.

The subject matter of the invention.

A machine for rolling telegraph tapes, characterized by the use of a movable flexible tape for increasing the density of rolling, with automatically varying length, covering almost the entire periphery of a reel of paper. SF.IG-1 |
