Transmission system is provided with said main frame such that to transmit the rotatory motion to the driven roller in order to rotate the same to facilitate the climbing of the machine on the palm tree. Brake means are provided near the lower end of the main frame to stop the machine at the desired height on the palm tree during the operation of the machine. A handle bar having acceleretor means at one end and the clutch lever at the other end is secured towards the top end of the main frame for controlling the operation of the engine and also to provide support to the climber during the operation of the machine. Locking means are provided near one end of the driven roller in order to stop the rotatory movement of the driven roller as and when required by the climber/operator. A wheal is provided on either sides of the engine compartment for facilitating the transportation of the machine to the desired site of operation. A power driven palm climbing machine according to a preferred embodiment is herein described and illustrated in the accompanying drawings wherein: Fig.l shows the perspective view of the power driven machine. Fig.2 shows the machine set with a palm tree in order to c1imb thereon. Fig.3 shows the transmission mechanism of the device. Fig.4 shows the locking mechanism and Fig.5 shows the brake means. Referring to the drawings particularly fig.l, the power driven palm climbing machine has a main frame i secured with an engine compartment 2 at the front end thereof. L shafts 3 are secured at the top end of the main frame 1 on either side thereof. The free ends of L-shafts are supported with the main frame by means of slanting supports 4. A driven roller 5 adapted to be driven by an engine through the transmission means is provided at the top end of the frame 1 rotatably for facilitating the climbing of the machine on the palm tree. The transmission means as shown in fig.3 comprising a drive sprocket 6 connected to a driven sprocket 7 by means of a chain 8 is provided to rotate a second driven sprocket 9 provided on a shaft 1(9 secured with the main frame 1 rotatably. The second driven sprocket 9 is connected to a third driven sprocket 11 by means of a second chain 12. The third driven sprocket 11 is provided at one end of the shaft of the driven roller 5 such that to rotate the same upon starting the engine. A guide roller 13 is provided near the free ends of the L shafts 3 for providing the support to the machine with the palm tree during the operation of the machine. The guide roller 13 is freely rotatable and is supported with the roller brackets 14 adapted to be secured on the L shafts by means of wing nuts 15. Means are provided to keep the guide roller 13 always in contact with the palm tree during the operation of the machine. Such means comprises a load spring 16 provided on either sides of the L shafts. The one end of the load mpring 16 is connected with the free guide roller 13 and the other end of the load spring 16 is connected to a steel ropes 17 wounded on winding drums 18 provided near the lower end of the main frame such that to provide required tension in the load springs 16 by rotating the binding drums by means of a handle 19 so as to provide the grip of the driven roller 5 and guide roller 13 on the palm tree on which the operator wants to climb. Brake means comprising a roller 20 provided with the main frame 1 and a brake rod 21 (as shown in fig.5) provided with the free end of the L shaft 22 are provided to stop the machine at a particular height. The brake rod is supported on the L shaft 22 by means of the bracket 23 having wing nuts 24 provided therewith such that to facilitate the removal to the refixing of the brake rod with the connecting rods 25. Further the brake rod 21 is connected to the brake paddle 28 through connecting rods 25 and connecting arms 26 provided on either side of the frame 1. Return spring 27 are provided to push back the brake rod 21 upon releasing the brake paddle 28 in order to bring down the machine on the palm tree. Lock means as shown in fig.4 are provided so as to lock the driven roller 5 of the machine. The lock means comprises a lock pin 29 provided with a H bracket 30 adapted to be secured with the main frame 1 at one side to lock the movement of the roller 5. The locking pin 29 is adapted to be operated by means of a steel rod 31 secured with the rear end of a lock pin 29 and passing over a pully 32 such that to give to and fro movement to the locking pin 29 by means of the lock control paddle 33 provided on the surface of the engine compartment 2 of the machine. A cylinder 34 is mounted rotatably on the lock pin 29 such that to allow the movement of the lock wheel 35 having locking holes 36 into one direction only. The lock wheel 35 is secured with a pre-wheel 37 adapted to be mounted on the shaft of the driven roller 5. To unlock the machine the lock paddle is pressed slowly. An operating handle 38 having an acceleretor 39 provided at one end and a clutch lever 40 provided at the other end is secured with the main frame 1 towards the upper end thereof for operating the engine. An off-switch 41 is provided with the operating handle 38 such that to stop the engine as and when required. A starter 42 is provided at the upper surface of the engine compartment to start the engine. Wheels are provided on either side of the engine compartment 2 for facilitating the transporation of the machine from one place to the other place. Carrying handle 44 are provided with the engine compartment of the machine. During operation of the machine the wing nuts 15 are unscrewed and spring roller 13 is removed to allow the trunk of the tree between the L shafts 3. The roller 13 is remounted on the L shafts 3 and is presssd towards the trunk of the tree by operating the load springs 16 by means of rotatating winding drums 18. Similarly, the brake rod 21 is removed from the L shaft 22 after unscrewing the wing nuts 24. The lower portion of the trunk of tree is also kept between the lower L shafts 27 and then the brake rod 21 is remounted on the L shafts 22. The engine is now started and the rotational motion is transferred to the driven roller 5 and thus the machine starts climbing up on the palm tree. Upon reaching at a required height the brake paddle 2S is pressed and simultaneously the driven roller 5 is locked in its position to keep the machine fixed on that height. When the purpose of climbing is completed the locking means are opened by operating the lock paddle and the brake paddle 33 is released to bring the machine down due to its weight and gravitational force. The machine is transporated to the other place and the above mentioned operational steps are repeated to climb-up on the other palm tree. 1 CLAIM: 1.
