RU2298233C1 - Harmonious bell - Google Patents

Abstract

FIELD: church property and musical instruments.

SUBSTANCE: harmonious bell contains body with suspension, striking device with striker and suspension. Bell suspension is provided with sound isolation, in form of, foe example, plastic bushing made of capralone, mounted in an aperture in upper section of body, in which a finger of suspension bracket of suspension yokes is positioned. Internal surface of bell body wall in striking zone along perimeter is formed by straight line, perpendicular to direction of striker impact vector, while impact surface of striker is formed by curved line, such as parabola. Suspension of striking device to body is made of two parts, eye and socket, mounted in upper section of body, interconnected by threaded connection.

EFFECT: prevented appearance of additional harmonics, no need for controlling position of point of contact of striker with bell body, and also quality realization of suspension unit of striking device.

Description

The invention relates to church property and musical instruments, and more particularly to bells used in evangelization in churches and temples, as well as in musical orchestras.

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 the body profiles in the longitudinal section are formed by radii of various sizes, including in the battle area (see N.I. Olovyanishnikov's book “The History of Bells and Bell Art.” M., 1912, p. 389 and others. ) [2].

Bells are also known according to patents US 3941082 A, 02.03.76 [3] and RU 2115959 C1, 08/12/96 [4], which describe bells containing tongues with strikers, and in which the inner surface of the wall is formed by curves of certain radii.

These bells, in their design, require regulation of the position of the contact point of the tongue striker with the bell body after factory manufacturing.

The present invention is aimed at improving the quality of the acoustic sound of the bell by eliminating the conditions for the occurrence of additional harmonics and elastic bouts, eliminating the need to adjust the position of the contact point of the tongue of the tongue with the bell housing during operation and ensuring high-quality performance of the movable suspension connection of the percussion device.

The essence of the present invention is to provide soundproofing of the bell suspension, to perform the inner wall of the bell housing along the perimeter in the battle zone in a straight line perpendicular to the direction of the striker’s strike vector, to make the striking surface of the striker in the form of a curved line, for example, a parabola, and to execute the suspension of the striking device to a two-part housing, a ring and a socket installed in the upper part of the housing, connected by a threaded connection.

Using the totality of the proposed technical solutions, it is possible to exclude additional harmonics from extraneous structures and from the rattling occurring due to a tangent impact of the striker on the bell case when the bell rings, it allows to achieve an elastic impact of the striker on the bell case, to ensure high-quality assembly of the moving assembly of the shock device suspension.

Thus, the quality of the acoustic sound of the bell is improved, which is especially important for the bells of musical orchestras.

The drawing shows a General view of the bell in longitudinal section.

The bell contains a housing 1, an opening 2 for a bell suspension, a soundproofing sleeve 3, a finger 4 for a bracket or clamps (not shown) of the suspension. The inner surface 5 in the combat zone 6 is formed by a straight line perpendicular to the direction of the striker 8 impact vector 7. The surface 9 of the striker 8 is formed by a curved line, for example, a parabola. Suspension of the percussion device 10 is made of two parts, the eye 11 and the socket 12 with a through threaded hole 13 installed in the upper part of the housing 1.

In the production of ringing, the presence of a sound insulating sleeve 3 eliminates the effect of additional harmonics on the resonant circuit of the bell from structures for which the bell is suspended. The presence of a surface 9 in the battle zone 6, which is formed by a straight line perpendicular to the striking vector 7 of the striker 8, eliminates the possibility of a tangential strike of the striker 8 against the body 1. Due to the surface 9 of the striker 8, which has a gentle shape, and the surface 5 of the battle zone 6, which direct in height, a large area of their contact is provided and, therefore, the elasticity of the battle. In addition, the deformation of the surface at the point of battle is reduced in comparison with the point contact of the surfaces formed by the radii. The execution of the suspension of the percussion device in two parts provides the ability to assemble a movable suspension unit outside the bell housing and thereby the assembly quality of the connected parts.
