Abstract: A bicycle bell includes a housing mounted on a handlebar and comprising a channel and an upward extending flange partially surrounding a top of the channel; a guide member secured to the housing; a drum secured to and covered the guide member; and a spring biased striking device mounted on the channel and comprising a bell lever and an opposite clapper extending through the flange to contact the guide member. Pivoting the bell lever about the channel will pivotably move the clapper to strike a first position on the drum after passing the guide member. Releasing the bell lever will return the clapper to its inoperative position after passing the guide member and striking an opposite second position on the drum. The bell is easy to manipulate with the same hand squeezing the brake lever.

Abstract: A bell device includes a housing having two housing members secured together, and one or more peripherals rib extended into an opening of the housing, a securing device includes a shank engaged in the opening of the housing, and includes a peripheral flange extended from the shank for engaging with the peripheral rib of the housing and for anchoring the shank to the housing when the two housing members are assembled together, a bell member is supported in the housing with the securing device, a clapper includes a stem pivotally attached to the securing device and a striking member for striking onto the bell member. A push rod may actuate the clapper to strike onto the bell member.

Abstract: A striker mechanism 21 which clangs a bell 21 is made up of a support member 31 which projects radially outward of the bell, a striker 41 pivotably mounted on the support member so as to be rockable in a direction toward and away from the outer peripheral surface of the bell, and a leaf spring member 41 for maintaining the striker at an intermediate position as viewed in the rocking direction which is by a given distance spaced from the bell. The striker is formed at its one end with an impactor 42 which impacts the bell and an operator 43 which operates the striker for rocking motion and is formed at the other end with a spring abutment 46 against which the leaf spring member resiliently abuts, an intermediate portion between the opposite ends being pivotably mounted on the support member so as to be rockable.

Abstract: A bell device includes a securing device attached to a bell member, a seat rotatably secured to the securing device with a shaft and rotatable relative to the securing device about the shaft, and a resilient member having one end secured to the seat and a clapper secured to the other end. An actuator rod may rotate the seat relative to the securing device, to actuate the clapper to strike against the bell member and to make sounds, without moving the bell member. A spring member may bias the seat to disengage the clapper from the bell member. The clapper may be caused to strike against the bell member when shaking or moving the bell member.

Abstract: A bell assembly in which the bell is mounted on a plastic base by means of a plastic collar snap-fitted into aligned holes in the bell and the bell mounting element of the base. The collar is formed with an axial bore for receiving a plastic manually depressible actuator.

Abstract: A display, such as a Christmas display, comprises a plurality of ornaments (14), each including a striker (18), a pair of bells (26, 27) disposed in spaced relation from the striker (18) and a means (46) responsive to an electrical signal from a control unit (12) for moving the striker into contact with one or the other of the bells (26, 27), at least some of the bells on the ornaments having different frequencies such that sequentially striking the bells (26, 27) plays a tune, such as a Christmas carol. The ornaments are preferably distributed about a Christmas tree, though alternatively they may be placed on a flat surface.

Abstract: A signal apparatus comprising a post-mountable arm adapted at one end to be mounted on a vertical stand post and having provided at the other end thereof a bell adapted to be struck by a counter-weight mounted on one end of a balance beam when blood reaches a predetermined level in a blood collection bag hung from the other end of the balance beam which is mounted on the said post below the said arm, and a hook adapted to receive a second bag removably hung thereon.

Abstract: An improved striker mechanism for percussion instruments such as chimes, bells, drums, and the like, is disclosed. A clapper is mounted on an armature for motion between a rest position and an impact position. A solenoid-permanent magnet set is provided to hold the clapper in its rest position. Energization of the solenoid by a short electrical drive pulse produces a magnetic field in the solenoid core which repels the permanent magnet and drives the clapper to impact a percussion instrument sound-producing surface. The drive pulse is sufficiently short that it does not impede rebound of the clapper, so that the rebound force cooperates with the magnetic attraction of the permanent magnet to the solenoid to return the clapper to its rest position, substantially without bounce, thereby producing a highly damped clapper motion.

Abstract: Energy is slowly stored in at least two spring members mounted juxtaposition one another, the stored energy being released substantially instantaneously and individually, a single member engaging a striker first, the striker then engaging an alarm device such as a bell, subsequent members striking prior members to move the striker and again engage the alarm device.

Abstract: A device for striking a bell comprises a hammer head having a head portion composed of hard material and another head portion composed of soft material to obtain both hard and soft sounding bell rings. The hammer head is connected to a rockable striking hammer lever which is driven with a rocking motion by a rotating eccentric cam to cause the hammer head to strike the bell. The center of rocking motion of the striking hammer lever can be shifted both manually and automatically to selectively vary the hardness and softness of the bell ring.
