Full Text | DEVICE FOR AUTOMATICALLY STOP AND START THE VIBRATION AND WATER SPRINKLING ACTION IN A COMPACTOR FIELD OF INVENTION This invention relates to an auto vibration cutoff device for use in a compactor, which is also responsible for automatic stopping and starting the water sprinkle action in an operational compactor. The auto vibration cut off device switches off the vibration and sprinkling mechanism when the speed of the compactor reduces. BACKGROUND OF INVENTION When the compactor is used for compaction of road edges or corners, and if the vibration device provided in the compactor is in an operative position, then the corners or end of the road is damaged. In compaction, the speed of the compactor is approximately 6 kmph, and when the compactor reaches the end of the road, the speed reduces and the driver makes a reverse pass. Often the passes are run on asphalt. Water is sprayed continuously on the drum to cool the drum. However, if water is continuously sprayed on hot asphalt, and the compactor is stationary, it suddenly brings the temperature of asphalt down, which is not desired. OBJECTS OF THE INVENTION An object of this invention is to propose an auto vibration cut off device for use in a compactor. Another object of this invention is to propose an auto vibration cut off device for use in a compactor which automatically stops and starts the sprinkling of water on the rotatable drums. Still another object of this invention is to propose an auto vibration cut off device for use in a compactor which is efficient. Further objects and advantages of this invention, including the method of realizing auto switch-off/switch-on of vibration as well auto stop/start of water sprinkle action, will be more apparent from the ensuing description. STATEMENT OF INVENTION According to this invention there is provided a device for automatically stop and start the vibration and water sprinkling action in a compactor in action, wherein it primarily comprising: a) a common shaft for mounting of the actuating levers, b) a cam mounted on said shaft, c) said cam having a cam follower forming a part of a microswitch to transmit a signal to a hydraulic vibration control and sprinkler controller. BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWINGS Further objects and advantages of this invention will be more apparent from the ensuing description when read in conjunction with the accompanying drawings and wherein: Fig. 1 shows schematic view of the arrangement of shaft, control levers, cam and other such devices towards realizing auto switch-off/switch-on of vibration as well auto stop/start of water sprinkle action. Fig. 2 shows: 2 Way Sliding Driver Seat DETAIL DESCRIPTION OF THE INVENTION WITH REFERENCE TO THE ACCOMPANYING DRAWINGS: Reference may be made to the Fig. 1. In accordance with this invention, the device comprises a shaft (1) having a control lever (2) at either end for controlling the speed and direction of drum. The shaft (1) has a cam (3) with a cam follower (4). The cam follower (4) forms a part of a micros witch (5) which sends a signal to a hydraulic vibration control valve for stopping the vibration of drum and water sprinkling. Actually, when a compactor makes forward and backward moves on a road under construction, it performs vibration as well as water-sprinkling actions. The driver operates the control levers (2) to control the speed and direction of the compactor's drums. At the time of changing the direction of movement of the compactor vehicle from forward to backward and vice- versa, the drive acts to reduce compactor's speed and he operates lever(s) mechanically. When control lever (2) rests in one particular position, as may be provisioned, the cam (3) of the shaft (1), say in forward position, remains in contact with the cam follower (4) of the microswith (5), and thus said microswith becomes capable of sends a signal to a hydraulic vibration control valve for starting the vibration of drum and water sprinkling. Further, when the driver operates any one of the control levers (2), the shaft (1) moves to reverse position, and therefore cam (3) of shaft (1) changes its position and loses its contact with the cam follower (4) of the microswitch (5). Therefore, due to loss of contact between cam (3) and cam follower (4) the microswitch (5) becomes unable in sending a signal to a hydraulic vibration control valve for starting the vibration of drum and water sprinkling. In this way, by operating the control levers (2) the driver of the compactor vehicle not only controls the speed and direction of the drums, but he also acts to automatic realization of switching off/on of the vibration as well as stopping/starting of water sprinkle action. Reference may be made to the Fig. 2. Further, the compactor has a seat assembly (6). The seat is mounted on a platform (7) having a pair of rails (8) extending in a first direction, namely the transverse direction. The seat has engaging means (9) to slidably engage the transverse rails so as to allow a movement of the seat in the transverse direction. Such a movement in the transverse direction allows an operator to work on the side of the compactor. (5). Therefore, due to loss of contact between cam (3) and cam follower (4) the microswitch (5) becomes unable in sending a signal to a hydraulic vibration control valve for starting the vibration of drum and -water sprinkling. In this way, by operating the control levers (2) the driver of the compactor vehicle not only controls the speed and direction of the drums, but he also acts to automatic realization of switching off/on of the vibration as well as stopping/starting of water sprinkle action. The device for automatically stop and start the vibration and water sprinkling action in a compactor, wherein the said device of the compactor which comprises a common shaft (1) for mounting of the actuating or control levers (2) and a cam (3) mounted on said shaft (10) and the said cam (3) having a cam follower (4), forming a part of a microswitch (5), to transmit a signal to a hydraulic vibration control and sprinkler controller characterized in that the contact between the said cam (3) and the cam follower (4) of the microswith (5) allows the said device to stop and start the vibration automatically and water sprinkling action in a compactor. Reference may be made to the Fig. 2. Further, the compactor has a seat assembly (6). The seat is mounted on a platform (7) having a pair of rails (8) extending in a first direction, namely the transverse direction. The seat has engaging means (9) to slidably engage the transverse rails so as to allow a movement of the seat in the transverse direction. Such a movement in the transverse direction allows an operator to work on the side of the compactor. The platform is mounted on a lower pair of rails (10). The platform has cngageable means (11) to allow a slidable engagement of the platform with said lower pair of rails and allow a movement of the seat in the second or longitudinal direction. It is to be noted that the present invention IS susceptible to modifications, adaptations and changes by those skilled in the art. Such variant embodiments employing the concepts and features of this invention are intended to be within the scope of the present invention, which is further set forth under the following claims:- WE CLAIM: 1. A device for automatically stop and start the vibration and water sprinkling action in the compactor, wherein the said device of the compactor which comprises: a) A common shaft (1) for mounting of the actuating or control levers (2); b) A cam (3) mounted on said shaft (10); c) Said cam (3) having a cam following (4), forming a part of a micro switch (5), to transmit a signal to a hydraulic vibration control and sprinkler controller, Characterized in that the contact between the said cam (3) and the cam follower (4) of the microswith (5) allows the said device to stop and start the vibration automatically and water sprinkling action in a compactor. 2. A device for automatically stop and start the vibration and water sprinkling action in a compactor as claimed in claim 1 wherein the contact between the said cam (3) and the cam follower (4) of the microswith (5) occurs due to the change of the position of the said shaft (1) and its said cam (3) and wherein the said shaft (1) having a control lever (2) at either end for controlling the speed and direction of drum mechanically. 3.
