DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIG. 1 through FIG. 3, the spring operated record player organ comprises a base apparatus 1, a driving unit 2, a gear set 3, a fixed axle unit 4, a record player 5, and a rotation speed governor 6.
The base apparatus 1 is composed of a comb leaf spring 11 and a ratchet wheel shaft 12. The ratchet wheel shaft 12 is provided with actuating wheels 121 and a player driving gear 122, whit both coaxially fitted to the ratchet wheel shaft 12. The comb leaf spring 11 is equipped at a position where it can be tapped by the actuating wheels 121 to output a rhythmical music when the ratchet wheel shaft 12 rotates.
The driving unit 2 has as spring cover 21 fitted at one side of the base apparatus 1. The spring cover 21 has a rotating shaft 211 piercing through its top surface. A first crown gear 212 is enclosed underneath the spring cover 21. A rotary switch 22 is provided at the other side where the rotating shaft 211 is coupled with the first crown gear 212. A coil spring 23 is wound around the rotating shaft 211. The rotary switch 22 is used to wind up the coil spring 23. When the wound coil spring 23 is released, the restoring force of the coil spring 23 drives the rotating shaft 211 which, in turn, drives the first crown gear 212.
The gear set 3 is equipped between the comb leaf spring 11 and the driving unit 2. The gear set 3 is composed of a second crown gear 31, a first step spur gear 32, a second step spur gear 33, a double helical gear 34, and a speed reducer 35. As the first and second crown gears 212 and 31 are in mesh with each other, the rotation of the first crown gear 212 puts all component parts included in the gear set 3 (second crown gear 31, first step spur gear 32, second step spur gear 33, double helical gear 34, speed reducer 35) in motion. The second step spur gear 33 mated with the second crown gear 31 then, in turn, drives the ratchet wheel shaft 12. Thereby, all of the ratchet wheels 121 are actuated to tap the comb leaf spring 111 with a proper rotating speed under control of the speed reducer 35.
The fixed axle unit 4 is provided with a set pin 41 and a fixed axle 42. The set pin 41 is located in the base apparatus 1 at the position distantly apart from the driving unit 2 and extended towards the direction apart from the base apparatus 1. One end of the set pin 41 is pivoted to the spring cover 21. The other end of the set pin 41 is provided with a hasp 421 to be inlaid into a circular slot 411 formed around the upper portion of the set pin 41 so as to fasten the fixed axle 4 in parallel to the ratchet wheel shaft 12. Additionally, several rotating wheels 422 are fitted with the fixed axle 42 coaxially in series.
A record player 5 is provided with a drilled hole 51 formed at its center to allow piercing the set pin 41 therethrough. A plurality of tapping apertures 52 are distributed at random on the surface of the record player 5. A plurality of driving holes 53 are formed around the record player 5 at the position near its fringe thereof. Thus, when the record player 5 is driven to rotate by the player driving gear 122, the driving holes 53 are able to positively mate with the player driving gear 122, since the record player 5 is pressed by the rotating wheels 422 of the fixed axle 42.
The rotation speed governor 6 is provided beneath the base apparatus 1 and the driving unit 2. As shown in FIG. 3, it is composed of a speed stabilizing cam 61 and a speed stabilizing wheel 62. The cam 61 is mated with the rotating shaft 211 at the end distantly apart from the rotary switch 22 for the coil spring 23. Additionally, the wheel 62 is in mesh with the cam 61. With the aid of the rotation speed governor 6, the operation of the mechanism is defined to take place during the time interval the restoring force of the coil spring 23 is at its most stable condition. Thus, the music can be played pleasantly to the ear with a stabilized rotating speed of the record player 5.
The speed stabilizing wheel 62 of the rotation speed governor 6 has a plurality of equally sized, equally spaced, similarly shaped teeth and one differently shaped tooth. The number of similarly shaped teeth matches with the length of the coil spring 23 and the stable restoring force acting time interval of the coil spring 23.
To operate the mechanism of the present invention, the mechanism is put on a platform or a desk. The hasp 421 is released from the circular slot 411 formed around the set pin 41. The drilled hole 51 of the record player 5 is inserted onto the set pin 41. Then, the hasp 421 is again inlaid into the circular slot 411 so as to mate the player driving gear 122 on the ratchet wheel shaft 12 with the driving holes 53 formed along the fringe of the record player 5. With the aid of the rotating wheels 422 of the fixed axle 42 pressed onto the record player 5, the driving holes 53 keep in mesh with the gear 122 without the worry of disengagement. The rotate the rotary switch 22 is rotated to wind the coil spring 23 around the rotating shaft 211 thereby storing the energy in the twisted coil spring 23.
After releasing the rotary switch 22, the mutually mated speed stabilizing wheel 62 and cam 61 begin to rotate together until reaching the last tooth. The coil spring 23 is able to drive the first and second crown gear 212 and 31 depending on its own restoring force. The gear set 3 is in turn actuated to rotate and drive the player driving gear 122 so that the record player 5 is driven to rotate. As the record player 5 rotates, the combined action of the driving holes 53 and the actuating wheels 121 makes the latter to tap the comb leaf spring 11 to output a pleasant rhythmical music. For stabilizing the operation of the mechanism of the present invention, action of the speed stabilizing wheel 62 and cam 61 cooperate to define the operation of the mechanism to take place during the time interval the restoring force of the coil spring 23 is at its most stable condition so that the music can be played pleasantly to the ear.
In addition, the position of the actuating holes 53 on the player 5 can be varied in accordance with the different melody so that it provides the individual user with a wide selection.
It emerges from the above description that the spring operated record player organ has several noteworthy advantages compared with that made of any conventional technique, namely:
1. The mechanism is operated by a manually twisted coil spring associated with several gear combinations so that any other extra power supply such as utility power or a battery unit is not necessary.
2. The rotary switch for twisting the coil spring is provided on top of the rotating shaft so it is convenient to wind up the coil spring without tampering with the base apparatus before rotating the record player.
3. The operation of the mechanism is defined to take place during the time interval the restoring force of the coil spring is at its most stable condition thereby the music can be played pleasantly to the ear.
Many changes and modifications in the above described embodiment of the invention can, of course, be carried out without departing from the scope thereof.
