ABSTRACT:
Discloses a conveyor-type, hydraulic-powered, material-spreading apparatus comprising a material-storage hopper, a conveyor for conveying material from the hopper for spreading same and a hydraulic, power-transfer system comprising two double-acting, hydraulic cylinders in communication with and operatively connected to valves which control and direct hydraulic fluid under pressure to the hydraulic cylinders to drive the conveyor. Each hydraulic cylinder has two drive strokes per cycle, with each drive stroke approximating 160.degree., each hydraulic cylinder is 90.degree. out of phase with the other, with positive drive resulting throughout the cycle.
Also discloses the hydraulic, power-transfer system described above for use in driving a conveyor for use with a material-spreading apparatus having a source of material to be spread, with such conveyor being disposed beneath the material for conveying same for spreading.
Also discloses a shock-absorbing device and limit stop for use with a member having a reciprocable element therein. Resilient bumper rings function as shock absorbers and limit stops upon abutment therewith of an end plate carried by the reciprocable element.
Also discloses a snap-action device for operative use with a reciprocable element in a member and with a reciprocating rod to reciprocate and slam the reciprocable element in the direction opposite to that being traveled by the reciprocating rod.
