It should be kept in mind that theprime mover throttle control means need not be manipulated, or changed to maneuver the vehicle. 3. The sprocket wheel 129 thereby contacts the chain 131 and applies a constant force against the chain in a direction substantially transverse thereto, hence subjecting the chain to tensioning forces. An amphibious all terrain vehicle as defined in calim-8, wherein said chain tensioning devices comprise in combination: a tensioning device mounting plate adapted to be secured to a structure; at least one elongated ratchet plate pivotally mounted at one of its ends to one end of said mounting plate; v. a plurality of ratchet teeth formed in an end of said ratchet plate opposite said end pivotally mounted to said mounting plate; a sprocket wheel adapted to operatively engage one of said chains to be tensioned rotatably mounted at said end of said ratchet plate contaning said ratchet teeth, and being disposed such that its sprocket teeth extend beyond the longitudinal edges of said elongated ratchet plate; first resilient means operatively associated with said ratchet plate biased to urge said ratchet plate to pivot about its pivot mounting in a direction generally toward said chain to be tensioned thereby causing said sprocket wheel to contact and apply a ,constant force against said chains to be tensioned thus keeping it in tension; a pawl adapted to engage said ratchet teeth pivotally mounted at one end to an end of said mounting plate opposite said end to which said ratchet plate is pivotally mounted, said pawl being disposed to prevent movement of said ratchet plate in a direction generally away from said chains to be tensioned; and. FIG. FIG. 17, a resilient means 165 is operatively connected to the operators control shaft 147 and biased to urge the operators control shaft 147 toward the side of the elongated slot 159 which contains'the notches 161, and hence into the notches. This resilient means is biased to urge the ratchet plate to pivot about its pivot mounting in a direction generally toward the chain 131 to be tensioned, i.e. This movement is accomplished by applying a bending force to the operators control shaft 167. An added safety feature is the units ability to float. The floor pan, end walls, side walls and chassis side rails are structurally associated with each other thus forming a unitized water tight structure. 1973 change ".logintudinal" to change "adjacne t" to change "Preferrably" to "of" to---or-. As best shown in FIGS. 22. The components of thechain drive system (see FIGS. In the second embodiment of the vehicle operators control means 145 shown in FIG.

The lost motion means includes at least two spring loaded control levers each pivotally mounted at one end to the control actuating means. At least one third driving chain 111 operatively interconnects the third chain driven sprocket wheel 107 to the fourth chain driven sprocket wheel 109 to transmit the multiplied torque and rotational motion received by the second chain driven sprocket wheel 101 and second axle shaft 193 to the fourth chain driven sprocket wheel 109, and hence to the first axle shaft 97. 2. 19 is a vertical sectional view of an alternate embodiment of the vehicle operators control shaft. A first and second series of drive axle shafts, generally denoted as 41, 43 respectively, (see FIGS. These ratchet teeth are adapted to engage the pawl. following "said"- insert following "said" insert" I change "driven" to drive-. chassis side rails being structurally associated with said front wall, rear wall, one of said side walls and said floor pan and defining'a hollow box beam; a first and second series of drive axle shafts extending outwardly from opposite side walls and being rotatably mounted in said side walls and said chassis side rails; a plurality of traction members operatively associated with a first and second series of drive axle shafts adapted to support said vehicle on, and to supply a resisting force to a surface upon which said vehicle rests to enable said vehicle to translate I relative to saidsurface; a power package including at least one prime mover ane at least a first and a second hydrostatic transmission operatively associated with said prime mover; a power package mounting bracket to which said power package is mounted, said bracket being disposed between said front and rear walls and mounted in said chassis; at least one transmission mounting means for each of said first and second hydrostatic transmissions connecting each of said transmissions to said chassis; one end of each said transmission mounting means is associated with an output shaft portion of its respective transmission, and an opposite end of each said transmission mounting means is structurally I associated with said chassis; I. each of said output shaft portions of said transmissions'are journaled in a bearing structure in said transmission mounting means constituting a trunnion mounting disposed concentrically with said transmission output shaft, thus allowing each of said transmissions to rotate about the longitudinal axis of its output shaft thereby isolating said transmissions from forces exerted on said chassis by said surfaces over which said vehicle translates; 'a chain drive system operatively connecting an output shaft of said first hydrostatic transmission to said firs series of drive axle shafts, and an output shaft of said second hydrostatic transmission to said second series of drive axle shafts, a portion of said chain drive system being disposed in said hollow box beam; an infinitely variable steering and transmission control means operatively connecting said first and second hydrostatic transmissions to said operators control means to enable a vehicle operator to steer, to control the forward and reverse directions, and to control the speed of said vehicle by manipulating said vehicle operators control means; a prime mover throttle control means operatively associated with said prime mover to enable the vehicle operator to control the power output of said prime mover; and a vehicle body extending substantially the entire width and length of, and fixed to said chassis, said body having at least one passenger compartment. resilient means associated with said operators control arm adapted to bias said operators control arm toward the longitudinal edge of said slot containing said spaced apart notches in said operators control shaft platform. SxS. 6. 20). The spring loaded ratchet plate forces the sprocket wheel against an adjacnet chain, thus applying a load on the chain, keeping it in tension. This causes the driving ratio of the first transmission to increase resulting in a transmission of more power to the drive system associated with the first transmission which increases the speed of the traction members on that side of the vehicle. 1 and 2, preventing any lost motion in the second control rod lever 185. 1. chassis frame on which a vehicle body may be mounted characterised by the vehicle type and not provided for in groups B62D21/02-B62D21/17, Motor vehicles or trailers, characterised by the arrangement or number of wheels, not otherwise provided for, e.g. 13 is a top-view of the drive chain tensioning device shown in FIG.
