Description

Pneumatic chime for church bells. The invention arises the task of creating a control device for the church bell, those at certain times connected with ecclesiastical activity sets the bell in action. Here is z. B. to the change in the mass of the Catholic Church, at which at a certain time the chime, z. B. by the sexton or sacristan, to be set in motion. If But this one, standing in the back of the church under the belfry, through the big one Number of church visitors standing in the church in his unobstructed view of the altar is disabled, the bell cannot be started in time, which is disturbing for some of the churchgoers. According to the invention, a Establishment to be created by, either the organist or the one at the altar Permanent sacristans can determine the point in time with sufficient accuracy, at which the chimes comes into action. For this purpose a device is provided in which the bell is activated by a simple remote control, namely useful: such a chime in which a hammer struck the bell will.

The invention consists essentially in that in the pneumatic, one. Hammer moving chimes for church bells an automatically filling and emptying bellows which can be moved by weak pressure and which can be controlled by a relay that can be activated from any point in the church. Through this relay, which can consist of a pneumatic valve, a compressed air line leading to the bell is filled with compressed air. The bellows moving the bells is brought into connection alternately with the compressed air line and the outside air, and the control of the bellows is effected by a special bellows which is automatically switched on and off at the end of the stroke of the large bellows. This automatic input and. The second bellows is switched off, for. B. by a slide that relieves a third bellows closing the supply line to the second bellows. To transmit the movement from the large bellows to the bells or their hammers or the like, a cam disk can be used, which has a number of cams and is indexed by one cam with each stroke of the large bellows. The bells or the other connection of the hammer or the bells with the chime is attached to a lever, which automatically slides off the preceding cam after the movement. The cam is held in the rest position by a locking lever and further switched from the bellows by a resilient lever with each movement one step each.

It is important that a remote control is connected to the bell that enables the sacristan or organist standing at the altar to pass through a simple one: press a button electrically or pneumatically to set the bell in motion.

In the drawing, the invention is exemplified, namely a means a wind tunnel of an organ which is connected to the valve box through the opening cc shown in dotted lines. In the bottom of the valve box, a double seat valve c is attached, which can be controlled by a bellows / shown in the folded state. Through this valve, the wind container a can either be brought into contact with the outside air or closed off from it. : According to the drawing, when the valve box is closed, the organ wind enters the bellows through a side channel against the outside air. The valve flap g is thereby closed and the valve box b is closed. The bells, which is connected to the valve box b through a channel h, which leads from the organ into the tower, is consequently put out of action. By admitting compressed air into the bellows f, which is effected by some electrical or other remote control from the sacristan or organist, the double seat valve c is lifted and the bellows "d" is brought into contact with the outside air. Under the pressure of the valve box b compressed air contained is compressed d of the bellows and the valve flap g opened so that the organ wind from the valve box b can 7i enter the channel. the Glockenseil i is connected to a lever k in communication moves from one with lantern wheels in-equipped disks This disc can be set in rotation by a lever o, which can be raised and lowered by a bellows p. A spring g presses the lever o again and again towards the headstocks m. A pawl o1 prevents the discs from rotating in the opposite sense: the bellows p is equipped with a pair of scissors r, which ensures that the parts of the bellows are guided in a straight line with a space through openings p2 in connection, which has an inlet valve z and an outlet valve u. These valves hang on the arm of a rocker v, at one end of which a rod w is hinged and a weight v is attached. Below the rod w there is a bellows x. On the side of the hinge p1, a slide j # -in .. is articulated on the bellows p and has an overflow channel j- ` and an outflow opening il. A double-walled tube aa opens into the slide mirror on which slide j slides, whose outer annular space is connected to a wind chamber b1 through channel a1, while the inside of the tube opens into a bellows y through channel a2. A double seat valve t is controlled by the bellows y, which alternately connects the bellows x with the wind chamber b1 or the outside air. Air from the valve box b and the channel lt can enter the valve box b1 through the opening, a3.

The mode of operation of the device is as follows: When the inlet valve g and the inlet valve z are open, the organ wind can enter the space s through the channel 7- and further through the overflow openings p = into the bellows p, whereby it is inflated. The upper part of the bellows will rotate in the direction of the arrow t and, with the help of the lever o and the headstocks m, set the disc, n in rotation and thus exert a pull on the bell rope i so that the bell comes into action. By moving the bellows in the direction of the arrow z, the S.c3ueber j is displaced in the direction of the arrow 2 .nadi below, so that now the outflow opening il of the slide occurs in front of the confluence of the double tube aa in the slide valve and this with it the outside air connects; this allows the bellows. y through the core tube a2. empty to atmospheric pressure, while an overpressure remains in the wind chamber bi, since the channel a1 Geg; over the inflow channel a3 is small. By compressing the bellows-'sy, the double seat valve t is lifted and the bellows x is brought into connection with the wind chamber b1 and lifted. He lifts the rod tv and thereby closes the Eir_laßventil z with simultaneous opening of the outlet valve and the bellows and the room can now to the outside air: (at bb) through the valve it: empty. The bellows p collapses, and the slide i is moved upwards again until the overflow channel j2 occurs in front of the confluence of the double pipe a- @ a in the slider level. As a result, the outer annular space of the double tube is connected to the core tube, and the organ wind can enter the core tube through the channel a1 from the valve box b1 via the flow opening j = and through the channel a = into the bellows y, so that this is inflated. By inflating the bellows y , the double-seat valve t is moved downwards and the bellows x is connected to the outside air, so that @ it can deflate. Now the rocker v lower, -r can move in the direction of the bellows x due to the effect of the weight v1 b °. This raises the egg valve and closes the valve valve. Now the process described begins again.

The slide b-b can be used to release the pressure which emerges from the bellows p Air achieved and thus one. Change of the train intervals on the bell string i achieved will.

The institution can not only be used for the purposes of the Catholic Church Find use, but also for other churches.
