Description

The main author's certificate No. 8234 describes a signal device for indicating the temperature rise of materials stored in barns, heaps, etc., based on an increase in air volume as its temperature rises. The expanding air presses against the diaphragm of the device, which thereby closes the electrical circuit.

The present invention is a modification of the described device and consists in the fact that the membrane of such a signal device, when the temperature rises, actuates through the lever system a helical spring emitting a signal flag.

In the schematic drawing of FIG. 1 shows a longitudinal section of the signal device; FIG. 2 is a top view of the part of the device with the flag folded.

In the proposed signal device, an adjusting screw, located against the middle of the membrane /, is screwed on an adjusting clutch G, which is connected to the short to the shoulder of the rotary axis 7

(365) /./, ..-.;., -

a lever 9 fixed on a stand “Y”, the long arm of which enters the slot of the rod Yu passing through the lid of the housing 2. The rod 0 carries a hairpin // designed to hold it in one of the extreme positions and a stud / 5 fastened to the spring f4, put on the rod fO and tending to push the latter into the tube M. Rod 0 is designed to hold the IS body carrying the rod / P with the flag 22 and pressed with the spring / 7 in the lower (n) position. The tube f6 with a protrusion 20 for placing the body S in it has a cover 2 / attached to the CTepwuie / P, which closes said tube / and with a single flag. When charging the device, the flag 22 is pre-folded, as shown in FIG. 2, and then, pressing on the cover 2 /, lower the body JS, while the rod fO, go into the tube / 6, will not hold the body with the rod. / 5 and the flag 22 in the lower position. At a certain temperature increase, which is adjusted.
