Description

The invention relates to instruments for recording and processing working time observations, provided with hand presser keys with counters installed on them, designed, when pressed on the keys, lowered in order to actuate them by frictional engagement with a drive device that crawls from the corresponding mechanism. . In the proposed device, a counter and a recording device in the form of discs, which are integral with the drums and have a knurling, are combined in one piece. The marked knurling, when applied at a certain scale, serves, on the one hand, to provide a stronger contact between the counting drums and the drive roller, and on the other hand, it is intended to apply marks on the dye paper.

In FIG. 1 shows a cross section of the device; FIG. 2 is a longitudinal section of it; FIG. 3 and 4 - details.

The proposed device (Figs. 1 and 2) consists of eight rows / ... VIl of vertically moving special-shaped rods a in the amount of eight brushes in each row.

(35)

In its upper part, each rod has a button 1-8 mounted on it, and in the opposite lower part there are drums b with c attached to axes fixed in the rod. discs n.

When the button is lowered, the drums L and C are in their extreme position - in the working state. The rod a is secured in this position by means of the clamp d and pressed by pressing the button under the bar e; Lastly, when the button is pressed, it is retracted by the latch to the side and again returns to its original position automatically, constantly pressed by the spring / from the opposite side.

When one button is pressed, the buttons, and all the other (one or several) buttons, which were in the working lower position, are automatically brought to the initial upper position (inoperative state). This is achieved by using permanent helical springs located under each button.

The guides for the rod are the edges of special-shaped holes cut in the cover sheets.

If necessary, all the drums

can be brought to a non-working (upper) position by moving aside the bar e with the help of the lever.

In the working state of the rods a, the drums b are inserted with their disc into engagement with the working roller g and the ink roller h. The work roller g bears on itself the paper fixed in its longitudinal slot.

During operation, the paper is wound on a work roll, driven by a special mechanism. The stock of paper is placed under each work roll in the form of a roll mounted on an idle, freely rotating roll k; the roll is braked by a flat spring / to prevent paper unwinding.

When rotating, the work roller g rotates the drum b rolling on it by the knurled disk.

In the disk of drum b there is a finger (Fig. 4), which, after each full turn, engages with the toothed disk of the drum, turning it at a certain angle. The axles of the drums and with serve simultaneously as pressure screws, preventing the springs from spontaneous rotation of the drums using springs.

Drums b v. with graduated circumference. Thus, the length of the line segments plotted by each drum is obtained by automatically summing these counters and thus at any time shows the amount of time fixed by the device, which, according to the meter readings, is recorded by the observer at the end of the observation directly on the graph in the corresponding line.

The driving rollers are set in motion by using the ditch p and from the end roller, which in turn receives movement from the propulsion device.

The establishment of a certain speed of the working rollers, depending on the required speed during timing, is achieved by introducing various gears of the device into engagement with the propulsion device and those of the outermost leading work roller by moving the handle t of the device to different positions. So, for the timing, the working roller speed b can be set: 1 rpm - one extreme position A of the handle, and for a photo - 1 rev / hour - another extreme position B.

The subject matter of the invention.

A device for recording and processing observations of working time, equipped with hand presses, with counters installed on them, designed, when pressed on the keys, lowered, in order to activate them, by frictional coupling them with a drive device receiving rotation from a time or other corresponding mechanism, which is combined in one common component of the counter and recording device, in the form of disks l, integral with the counting drums b and having a knurling, which, and applied on a certain scale, serves on the one hand to ensure a stronger contact between the counting drums and the leading roller, and on the other hand to mark the paper wound on the roller g, for which the disks n are in contact with the paint roller h. to the author's testimony of M.
