Title of Invention

AUTO DRUM BELL UNIT

Abstract

The aim is to provide an electrically operated fully automised beNing system for use in temples. It is an integration of three units, disc shaped bells, conical shaped hanging bells and the drum, synchronized for operational activities, power derived from an electric motor. The drive mechanism is through a gearbox-pulley arrangement, belt driven by the motor. Gearbox assembly carries a set of gears, which in turn activate cams, striking harmony between the instruments. A lever, adjoining the gearbox assembly, carrying nylon chords on either sides, actuates the conical shaped hanging bells. The lateral movement of the lever is converted to linear motion by a nylon roller. The hammers at either ends are actuated by cams, which strike the disk shaped bells, roller cams bolted to the gear body actuates the drum sticks, exerting a striking force on the drum. The conical hanging bells are supported on a tubular frame.

This Invention "AUTO DRUM BELL UNIT" is aimed at r.*oviding an exclusive automised belling system for use in temples, which is electrically operated, which has been manual all these years. Use of bells and drums has been customary in all Hindu temples. In particular, at the time of arathi, it is seen that the use of these bells and drums is maximum and it is believed in the Hindu Mythology that by doing so, one is drawing the attention of the respective God/Godess. This process involves the active participation of atleast two to three people, one to operate the disc shaped bells, one to operate the conical shaped hanging bells and yet another person operating on the drums. However, the divine music emanating from these operations lacked synchronization, most of the times would be of a mis-match, consequent to which it would be a mere corrobation of deafening sound, leading to unpleasantness. Another main objective of this invention is to totally eliminate the man power required by electrically operating the device, which is totally automatic. Further, this Invention "AUTO DRUM BELL UNIT" is compact, even portable models being made available. Moreover, there is "Unity of Place in contrast to the conventional methods, wherein different people would operate from different positions, whereas this system starts operating as a total integral unit by just operating a switch. Another important feature of this "AUTO DRUM BELL UNIT" is that the operational aspects of all the instruments ie., the disc shaped bells, conical hanging bells and the drums have been so synchronized by using suitable cams, which results in harmonial devotional music and is not just deafening sound, which otherwise used to be. "AUTO DRUM BELL UNIT" basically is the integration of three units, ie., the disc shaped bells (7), conical shaped hanging bells (8) and the drum (9), synchronized for the operational activities, with the power being derived from an electrical motor (1). The motor (1) is placed above the gear box assembly unit (11), which carries all the gears and the cams. Torque is transmitted to the gears through a pulley (2), which is belt-driven by the Motor. The Gear Box assembly (11) carries a set of gears and the gear shaft carries a set of cams (5). Roller Cams are screwed and bolted on to the gear body. The Cams and the Roller Cams are designed in such a way that a perfect harmony is struck between the instruments, when the "AUTO DRUM BELL UNIT" is switched on. A Lever (12) adjoining the Gear Box Assembly (11) on either sides carrying nylon chords, actuates the conical shaped hanging bells. The upward and downward movement of the lever, which is by virtue of the cam, is transmitted into linear motion by virtue of a nylon roller. Next, the hammers (6) on either ends are also actuated by the cams, which strike on the disc-shaped bells (7) . Roller Cams (4) are bolted on to the gear body, which actuate the drum sticks (10) exerting a striking force on the drum. The Gear Box assembly unit (11) and the Drum (9) are placed one besides the other on angular frames, which forms the adjustable pedestal (13) , A channel is provided on the pedestal on which the drum (9) is mounted in such a manner that it could be moved linearly and locked at any particular position by means of a knob. The drum is moved linearly, periodically in order to ensure that the drumsticks do not strike on the face of the drum at the same surface constantly, which would otherwise result in a faster wear and tear of the drum surface * Fig (B) & Fig (C) on Sheet No: 2 & Sheet No: 3 of the accompanying drawings, represents the schematic arrangement of the gear, cams and the roller cams and the manner in which they are linked to the three sets of strikers-Cams (5) derive their rotary motion from the Gear Shaft and is assembled in a manner as shown in Fig (B) on Drawing Sheet No: 2, which take care of the harmonious striking of the disc shaped bells and the conical hanging bells, whereas the Roller Cams (4) which are screwed and bolted to the gear body, take care of the drum sticks (10) that beat on the Drum (9). As the working of the cams and the roller cams have been linked with the movement of the gear and the gear shaft, the whole system operates as a single integrated unit, leaving no scope to any mis-match and thereby resulting in harmoniai devotional music. As already enumerated, no manual power is required for working of each of these basic units. I Claim, 1) AM AJTO DRUM BELL UIIT' which is electrically driven by a motor-pulley-gear arrangement, wherein an adjustable Pedestal (13) positions a Gearbox Assembly Unit (11) at one end and a linearly movable Drum (9), which could be moved on a channel, through the remaining part of the pedestal and could be locked at any position therein, to ensure that the striking force from the Drum Sticks (10) does not strike at one place constantly and is distributed throughout the face of the Drum; Disk shaped bells (7) and Conical Shaped Bells (8) fixed to Tubular Frame (14) , Drum Sticks (10) for the Drum, Hammers (6) for the Disk Shaped Bells, Nylon Chords actuated by Levers (12) for Conical Shaped Bells respectively, being used as the striking force, all deriving power from the Electrical Motor, wherein the Gear Shaft with cams attached to it is driven by a Belt-Pulley Drive (2) and the Roller Cams (4) are bolted to the Gear Body.
