JÜRGEN BÖTERN in WILSTER (Schleswig-Holstein). Device for ringing larger church bells.

Patented in the German Empire on July 4, 1877.

This device for ringing large church bells aims to save energy when ringing, Avoiding the shocks of the tower, longer durability of the bells by placing the same Jump less easily and produce a rhythmic, harmonious and far-reaching ringing sound.

Since the bells are firmly attached, the hammers are set in motion by a mechanism set; this saves a lot of manpower. There the bells in the tower get stuck, the tower has almost no shock, and because the hammers are open strike the outside of the bell, so there is no risk of cracking; because the Bells endure much stronger blows on the outside than on the inside, and because of that Immediately after striking the hammer, it was thrown back by a strong spring and by the Bells is held, i.e. cannot linger at the bell, is the sound of the same pure, bright and resounding; and because furthermore the hammers are set in motion by a mechanism you get a perfectly rhythmic and harmonious peal. Are in There are several bells on one tower, and it would be desirable to have them on the smaller one The bell should have more strikes than the big bell, so this can be arranged very well, whereby the peal stays in time. With the mechanics the inventor has a device connected, with which one can give signals in the event of a conflagration and the like.

In the accompanying drawing, FIG. 1 shows the mechanism in a perspective view and FIG. 2 shows it from above. The bells are fixed immovably; the strikes of hammers A are regulated as follows: When the hammer is at rest, it is carried by spring B ; this spring throws the hammer back from the bell immediately after it is struck. The action of the hammers is regulated again by the thumbs C, which are fastened to the shaft D in such a way that, as the shaft rotates, they alternately raise the hammer up and down again, and it strikes the bell. The wave D noticeable in the drawing is provided with two thumbs for each hammer. On one end of the shaft on the right is a gear E, which is turned with the aid of the drive F, on whose shaft G a flywheel H is attached. The translation number can be chosen at will. The thumbs take turns pulling the hammers up and dropping them on them. It can be seen that the attack against the bells occurs in rhythm. If only one bell is to be rung, the mechanism can easily be arranged so that the other bells can be turned off.

At the left end of the thumb shaft D there is also a toothed wheel which engages in the roller wheel / on the signaling device. The latter engages on the other side with a gear, the shaft of which carries a heart at the other end, and at the same time this gear engages with the other side in a drive whose shaft carries the vestibule or regulator and the starter at the other end. Above the heart and the starter lies the release arm K. A string with a weight is attached to the weight roller; if the latter is opened with a suitable key, it is held by the release arm K ; if one lifts arm K and lets it fall again immediately, there is only one blow on the bell; if you hold the arm K up longer, the whole ringing is in full swing until you let the trigger arm K fall, or until the weight has run out. The weight raised to the signaling device does not prevent the ringing, because a disc with a locking spring or ratchet wheel is attached to both wheels on the thumb shaft on the left and right; therefore each work can be used on its own.
