  • Patent number: 8669450
    Abstract: A protective coating is applied to a bell body composed of bronze by simply dip-coating the bell with an outer layer of zinc. The process is carried out by immersing the bell body in a hot aqueous solution containing sodium hydroxide and powdered free zinc. After the bell is removed from the coating solution it is rinsed and then polished. The coating protects the bell from environmental contaminants without changing the frequency or musical quality of the bell and therefore may be used equally with newly manufactured or refurbished bells.

  • Patent number: 8371250
    Abstract: A non powered, canine barking suppression device that can rapidly altering a dog's behavior so as to visibly reduce anxiousness and unwanted barking. The device subjects the dog to random vibrations and audible tones generated by an enclosed tuning fork that is worn around the dog's neck. The tuning forks when struck, emit a selected frequency selected for a specific purpose and or specific breed of canine. This frequency lies between 0 and 200,000 Hz, which is the range of sound that has been shown that most canines can hear. Since it is non powered it is not prone to failure in wet or cold environments, is durable and inexpensive. The device has claims of additional therapeutic properties and the general physical structure has applications elsewhere, although the preferred embodiment and best mode are directed to stopping unnecessary barking.

    Abstract: A wind chime constructed according to the invention includes a rotating wind bell apparatus having a downwardly opening bell that is adapted to be suspended from a separate support structure. A bell-striking mechanism in the form of a striker is suspended movably from the bell in a position to strike the bell. A striker-moving mechanism in the form of an impeller connected to the striker causes the striker to move in response to a wind moving past the striker-moving mechanism and to strike the bell so that the bell produces a tone. A bell-rotating mechanism in the form of another impeller connected to the bell causes the bell to rotate in response to the wind moving past the bell-rotating mechanism in order to thereby vary the tone and produce tremolo or Doppler-like effects. In one embodiment, the bell-rotating mechanism includes a Savonius type impeller attached to the upwardly facing surface of a circularly shaped impeller base.

  • Patent number: 5275080
    Abstract: A windchime that generates musical tones in response to very low wind speeds includes chime members that are grouped in pairs. The chime members of each pair of chime members include a massive chime member and a less massive chime member that are closely spaced apart from one another. In very low winds, the less massive chime members begin swinging and impinge against their adjacent more massive chime members. Thus, a musical tone is produced even before the more massive chime members begin swinging. This arrangement of parts reduces the sensitivity threshold of the windchime so that it performs its intended function in breezes moving at less than one-half a mile per hour. In a preferred embodiment, three sets of chimes are suspended from a tripod-like mounting member that includes aesthetically pleasing support legs.

  • Patent number: 4566400
    Abstract: An improved bell is disclosed which features a clapper continuously adjustable for hardness of strike. The clapper comprises a hard inner member and a resilient outer member. The periphery of the clapper is circular but the hard inner member is not circular about the same center as the periphery so that the amount of resilient material between the solid inner core member and the periphery varies circumferentially around the clapper. At the time of manufacture of the bell it is tested to locate the point on the bell body at which "wow and flutter" in the tone emitted by the bell is minimized. A single insulated pin serves to orient the handle of the bell, the bell body and the plane of swing of the clapper. The attachment of the handle, the bell body and the clapper is such as to minimize extraneous noise. An elastomer clapper shaft is employed, and its effective flexing length may be varied.
