Abstract

The bell ringing mechanism with casing (1) is made of stainless steel and antimagnetic material and it is consisted of a brass impact ball (9) and a shock intensity adjusting screw (2) held by a safety nut (3). It has the advantage of being able to adjust the bell impact intensity thus achieving maximum sound performance combined with minimal wear for bells 10 of any weight and morphology.

Description

  • The invention relates to a bell mechanism, the main components of which constitute the mechanism being A the antimagnetic casing, the electromagnet (coil), C the shock piston and D the impact intensity adjusting screw.
  • Bell impact mechanisms with coil and piston are known. In those mechanisms, the piston hit the bell with certain force. If the power impact is small relative to the particular bell, there is low sound performance and if the impact force is greater than the bell, in the long term the bell is worn or cracked.
  • To solve the above problem, 8 or more different sizes of impact mechanisms are used (depending on the manufacturer) trying to reduce the problem without being able to solve it. The weight of a bell that often starts from 25kg and reaches the BO ChB and its morphology (wall thickness, diameter, style) varies to such an extent that it becomes impossible to achieve maximum sound performances combined with minimal wear in all bells from mechanisms without adjustable impact intensity.
  • The second major drawback of the above mechanisms focuses on their construction. The cover which encloses the electromagnet is made of magnetic materials (cast iron or iron). This results in part that the magnetic force generated by the electromagnet being absorbed by the cover thereby reducing the impact force of the piston (which is also made of magnetic metal, iron) and resulting in increasing construction costs of the coil since a larger coil is used to achieve the required impact force. Additionally, it is necessary to paint the casing of the mechanisms and their maintenance, especially in coastal areas, is necessary to protect them from oxidation and extreme weather in the bell tower.
  • The advantages of this invention are that the impact force of the piston is adjustable and thus maximizing the sonic performance in conjunction with minimal wear for bells of any weight and morphology.
  • Due to the adjustable impact intensity, a single impact mechanism size can cover a wider range of bells compared to mechanisms which do not have adjustable impact strength. As a result, the set of different sizes impact mechanisms required to cover the different bell weights (often from 25 kg to 800 kg) is reduced by half.
  • Due to the anti-magnetic stainless steel casing that does not absorb magnetic force when the coil is set in operation, the impact mechanisms have lower coil construction costs and do not require protection and maintenance from oxidation and outside conditions.
  • The mechanism consists of the stainless steel and antimagnetic casing (1), the impact tension screw (2) held by the safety nut (3) attached to the casing and the safety adjustment bolt (4) which prevents the impact tension screw (2) to be screwed when it reaches its end.
    It is also comprised of the coil (5) which is held by the secured coil (6) by a circular plate pressing the casing, the axis (7), which is protected by a collapsible protective rubber shaft, (8) where it is screwed the brass impact ball (9) and the magnetic mass (10), i.e. the mass drawn to the magnetic traction 15 of the coil when it is activated, as well as the internal rubber which absorbs the vibrations (11) located in a recess in the rear of the magnetic mass (10).
  • Figure 1 shows the device in section.

Claims (6)

  1. The device is characterized in that the casing (1) is made of stainless steel and anti-magnetic material and has a brass impact ball (9) and a shock intensity adjusting screw (2) held by a safety nut(3) a shock absorber (11) disposed in a recess on the back of the magnetic mass (10).
  2. According to claim 1, the mechanism is characterized in that the impact tension screw (2), when screwed onto the safety nut (3), pushes the magnetic mass (10) further forward of its original position. As a result, the magnetic mass (10) when it is magnetized by the coil(5) travels shorter distance until it reaches the center of the magnetic pull of the coil (5) and this results in less bell impact force.
  3. In accordance with claim 1, the mechanism is characterized in that the impact tension screw (2), when unscrewed in the safety nut (3), leaves the magnetic mass (10) pushed out of gravity beyond its original position. As a result, the magnetic mass (10) when magnetized by the coil (5) travels longer until it reaches the center of the magnetic pull of the coil (5) and this has as a result less impact force of the bell.
  4. In accordance with claim 1, the mechanism is characterized in that the stainless steel & antimagnetic casing (1) of the device is not magnetized when the coil is switched on.
  5. According to claim 1, the device is characterized by the internal rubber, which absorbs the vibrations, (11) which is affixed to a recess in the back of the Magnetic mass which prevents the wear of the magnetic mass (10) and the impact tension adjusting screw during reset.
  6. According to claim 1, the device is characterized in that the brass impact ball (9) is made, entirely or partially, of brass on the contact with the bell during impact, thus, reducing wear on the metal of the bell during impact.
