Title of Invention

EFFECTIVE LOAD MOVER LEVER

Abstract Effective load mover lever" moves vehicles by balancing major pan of weight of vehicle on the point of virtually increased friction of road resistance and human effort. In a tricycle, instead of crank-sprocket and chain, front lever, hinged at centre of front side structure, rests on a rolling point which is fixed on one end of main lever. The main lever is hinged at the backside structure. Resultant force available at one end of main lever lift effects the backside structure about a shaft fixed on the circumference of the input sprocket of speed increasing device whose output is connected to shaft of back wheels to drive. Hence the vehicle is set to motion.
Full Text A. Background for the invention of Effective load mover lever
'Effective load mover lever' is related to field of Mechanical / & Automobile Engineering. It is possible to increase the speed of bicycle or tricycle with only 1C engines, battery operated motors, etc. Gear systems are available for bicycles only; even then speed is limited.
When compared to cycles and motor car, 'effective load mover lever1 moves vehicle by human effort through levers, requires no fuel and IC engine, has gear box with incremental gear ratio, no clutch is required to change gear stage, speed achieved is as that of a motor car while cheaper than it, economical even for single seated, uphill requires effort as on plains, gives out no pollution. The object is to bring forth cost effective, smokeless, fuel independent and safe travel vehicle. The aim is to move and increase speed of a light vehicle under application of possible human efforts only.
B. Brief description of drawing:
In fig (i), in a tricycle instead of crankshaft and chain, front lever (1) is hinged (9) at front side. This lever rests on a bearing (3) fixed on an axle and the main lever (2) holds this axle. The main lever (2) rests freely on a shaft (4) fixed on the circumference of a sprocket (7). This sprocket is free to rotate on its axis (6) and drives the speed increasing device (8) whose output is connected to back wheels (10). The other end of main lever is hinged at two points (5) at backside of vehicle.
In fig (ii), part of smaller gear forming part of front lever and part of bigger gear forming part of main lever (3') are coupled directly, instead of front lever resting on bearing as in fig(i).
C. Summary of the invention:
With reference to fig(i), when effort is applied at free end of the front lever(l), part of front load is lift effected, the resultant gets applied on the rolling point(3) of one end of main lever(2). In the case of fig (ii), the resultant gets applied to main lever through coupled gear teeth. Th* main lever is arranged to get pivoted on the shaft(4), on the point of virtually increased friction of road resistance, i.e. the input point of speed increasing device, the output of which is connected to back wheels. The other end of main lever is hinged at the backside structure and hence part of backside load is lift effected.
Hence part of total weight of the entire structure and human weight overcomes the virtually increased friction of the road resistance. The vehicle is then set to motion. More levers can be arranged in tandem for heavy vehicles and is applicable to compact, all vehicles.

D. Description of the invention:
The force required to be applied for a bicycle or tricycle to move is through human effort and weight which is just sufficient to overcome the static friction of road resistance. The speed attained is about 15 km./hr. For increasing this speed twice or thrice, speed increasing device can be provided but that will increase the requirement of more effort. This effort will be very much higher than that of humanly possible.
A tricycle is constructed to get good balance and to cope up with speed. To overcome the problem of increased requirement of effort, levers are so arranged, to lift effect the front and backside of the tricycle, in tandem linked on rolling point as in fig (i) and coupled directly through gear teeth as in fig (ii).
Thus part of weight taken from front side is utilized along with effort applied. The resultant gets applied on the rolling point of one end of main lever as in fig (i) and on gear teeth as in fig(ii).
The main lever is arranged to get pivoted on the point of virtually increased friction of road resistance i.e. at the input point of speed increasing device. The other end of main lever is connected at two hinged points of the backside structure.
This arrangement shifts part of total weight of the entire structure and human weight to overcome the virtually increased friction of the road resistance; and the road resistance is that of the remaining part of weight of entire structure + human weight.
The main lever is free to rotate on the shaft fixed at an extreme point of sprocket no. 1. This point of balance is to lift effect the backside structure and to apply effort to move and increase speed. On application of effort at this effort end of main lever the backside structure is lift effected because of virtually increased road resistance is available at the point of balance.
Thus the effort-weight is increasing at the point of balance while the virtually increased friction starts reducing. When these two, force & friction, matches the vehicle starts to move. The speed depends on turns ratio of speed increasing device and weight of the system. Effort needed gets reduced when the vehicle moves and it never exceeds its initial value when the vehicle starts to move and can be fixed to any value of our choice by adjusting length of lever.
Two more similar arrangements can be made at right or less than that at front and back side and effort levers of these sets can be moved down through cam arrangement for moving the vehicle up and down the hills. Reverse gearing is possible by providing one more free wheel on the shaft of back wheels and by engaging opposite phase of forward gear train. The gears can be arranged in steps and levers can be arranged in tandem for heavier vehicles.
