Addendum to patent 205570 of October 27, 1907.

Patented in the German Empire on December 5, 1911. Longest duration: October 26, 1922.

The invention relates to an arrangement of the safety device described in the main patent for signal systems in connection with a special locking device through which not only the signal circuit for the execution signal from the hanging bench to the hoisting machine remains locked until all floors of the suspended bench have given their ready signal have, but also the communication signal from the attacker on the sole has arrived is. For this purpose, according to the invention in the sole signal circuit on the A special relay is switched on by the hanging bank, which is activated by pressing the signal button on the Sole is made to respond while simultaneously sounding the impact alarm. In the drawing, for example, a circuit arrangement for the promotion is schematically shown shown in mining operations with multi-storey hoist cages.

The arrangement is intended in such a way that there is a blocking device on the frame of the suspended bench and on the shaft frame of the floor, which are independently and electrically connected to one another by the lines 10, 11. The attacker on the sole can transmit the finished signal to the attacker on the hanging bench by triggering the alarm clock W by moving the signal button t _i , whereupon the attacker on the hanging bench after all lamps S ₁ , S ₂ , S ₃ , s _{4 have} been lit by pressing the Key A, the so-called execution signal key, forwards the signal to the hoisting machine, which is indicated to the machinist by the sounding of the alarm clock PF ₂ .

The device works as follows:

Suppose there is a cage on the floor and one on the hanging bench. As soon as one of the conveyor cages on the floor is emptied or filled, all keys I ₁ , t ₂ , t _{3 have been} pressed, causing the signal lamps Sj, s ₂ , S _{3 to} light up when the striker is on the floor. By pressing the t _i button, the striker on the floor now gives the ready signal to the striker on the suspended bench so that the conveyor cage can move up the floor.

When the button £ _{4 is moved} , a current flows from the positive pole of the battery Q via line 7, line 11, contact of the blocking relay B, alarm clock W ₁ , button i ₄ , line 10, relay A ₄ , alarm clock W, line 12, back to the negative pole of the battery Q. The alarm clock W ₁ sounds, and the relay A ₄ attracts the armature a _x . This closes the following circuit: Positive pole of battery Q, line 7, blocking relay B, line 8, via the adjacent contact of the signal button A, line 5, breaker button UT, anchor a _v lamp s ₄ , line 13, line 6 back to

negative pole of battery Q. The signal lamp S ₄ thus lights up.

When the relay h _{i picks up} its armature a _x , the left contact of the armature is interrupted and thus the blocking relay B is de-energized. Simultaneously with the lighting up of the lamp S ₄ , the blocking of the signal circuit to the hoisting machine is canceled. Then the attacker on the

ίο Pass the signal to the hoisting machine in the known manner by pressing the signal button A on the suspended bench. Here, however, it is assumed that the conveyor cage on the hanging bench must also be emptied or filled, which is indicated to the attacker by the lighting up of the signal lamps S ₁ , S ₂ , S ₃ .

The purpose of the switch Sch is to switch off the safety device on the floors during normal material transport and only to leave the wake-up signal circuit closed.

In conjunction with the buttons t _v t ₂ , t ₃ , a special circuit for a special alarm clock can also be placed on the hanging bench and on the sole, in order to simultaneously give a temporary warning signal when the buttons t _x to t _{3 are moved.} This can e.g. B. be achieved in that the buttons t _x to t _{3 are used} double-pole to lead a separate circuit for the special alarm clock on these buttons, or by using relays V _x to r ₃ with double winding, the one as Holding winding is used, and the second is placed as a pull-in winding in the circuit of the special alarm clock.

Patent-An saying: Safety circuit on signal systems, in particular for the transmission of the conveying signals in mining operations with multi-storey conveyor baskets according to patent 205570, characterized in that a special relay (hj is switched on in the bottom signal circuit, which receives current when the finished signal is given from the bottom and which is tightened by its armature ( CL ₁ ) de-energizes a blocking relay (B) influencing the forwarding of the signals, for the purpose of not only keeping the signal circuit for the execution signal from the hanging bank to the hoisting machine blocked until all floors of the hanging bank have given their finished signals, but also until the communication signal from the sole has arrived. 1 sheet of drawings.
