RU2380764C1 - Bell for musical bell-tower - Google Patents

Abstract

FIELD: physics.

SUBSTANCE: bell for muffling its own sound has a muffler made in form of a lining in contact the housing in the initial position of the striking head. The lining is mechanically joined to the striking head, providing for movement of the lining away from the housing before the head strikes the housing, thereby not disturbing sounding of the bell. After striking, the head moves away from the housing and the lining of the muffler lies on the housing and kills the sound of the bell. To make a sound, a remote controlled electromechanical actuator is used together with a hand-held striking head.

EFFECT: provision for required time for sounding each separate bell or an accord of bells when sounding bells of a bell-tower in which bells have different sound tones.

Description

The invention relates to musical instruments, and more particularly to bells used in musical orchestras, carillons, in church and temple belfries.

The literature describes bells of various shapes and sizes (see the book by N.N. Rubtsov "History of foundry in the USSR", part 1, section 2. Mashgiz, 1947) (1). Bells are known in which different methods of ringing are used to excite sound: they strike the bell with the tongue or swing the bell and it strikes the tongue.

The way a tongue strikes the bell case when ringing affects the tone of the sound (see N.I. Olovyanishnikov's book “The History of Bells and Bell Art.” Moscow, 1912, p. 392 and others) (2).

Bells are also known according to patents US 3941082 A, 02.03.76 (3), RU 2115959 C1, 08/12/96 (4) and RU 2298233 C1, 08/19/2005 (5), which describe bells containing tongues with strikers.

In well-known bells, with their design, in the production of ringing, sound after a stroke of the tongue against the body sounds for a certain period of time. At the next striking strikingly on another bell, the fading sound of the previous bell is superimposed on its new sound. As a result of such a battle, the phenomenon of distortion of the sound of the belfry as a whole occurs. Such use of bells with different tones creates certain difficulties when used in orchestras, carillons and belfries.

The present invention is directed to obtaining the required playing time of each individual bell or chord of bells in the production of ringing by bells of the belfry, in which the bells have sounds of different tones.

The essence of the present invention lies in the fact that the bell to muffle its sound contains a silencer made in the form of a lining that is in initial position in contact with the bell housing, and the lining is mechanically connected to the shock striker, allowing the lining to be removed from the housing before the striker hits the housing without interfering the sound of the bell. After the strike, the firing pin moves away from the body, and the muffler pad rests on the body and dampens the sound of the bell.

For the production of ringing, along with manual combat, an electromechanical drive with a remote control is also used, for example.

The use, for example, of an electromechanical drive with a remote control allows you to provide the necessary strength and frequency of impact of the striker at a distance.

Figure 1 as an example shows a General view of the bell in longitudinal section with the tongue in its original position and with an electromechanical drive. Figure 2 shows the same view, but with the position of the tongue at the time of impact. The remote control is not shown.

The bell contains a housing 1, an impact device in the form of a tongue 2 with a striker 3, a muffler pad 4, an electromechanical drive 5 and a manual drive 6.

In the initial position of the bell, the firing pin 3 is located at a distance from the battle zone of the body 1, and the muffler pad 4 is in contact with the body 1. During the production of ringing, the firing pin 3 is moved to come into contact with the body 1, causing a sound, and the muffler pad 4 moves away from the surface of the bell body 1. After the end of the impact, the firing pin 3 departs from the housing 1, and the muffler pad 4 rests on the housing 1, damping the sound of the bell.

Using the totality of the proposed technical solutions can improve the sound quality of a group of bells, which is especially important for bells of musical orchestras and carillons.

Claims (1)

The bell of the musical belfry, comprising a body and a percussion device, characterized in that for silencing its sound, the bell contains a silencer made in the form of a lining that is in initial position in contact with the bell housing, and the lining is mechanically connected to the shock striker, allowing the lining to be removed from the body before impact the striker on the case, without interfering with the sound of the bell, after the strike of the strikers moves away from the body, and the muffler pad rests on the body, damping the sound of the bell, and to produce a ringing, along with nym battle, as used, for example, electromechanical drive with remote control, by using the set of technical solutions achieved high-quality sound of musical bands and carillon.
