PROP SPRING ASSEMBLY (Cont'd)

In an electrophotogra hic printing machine, a serviceable feature is accessed

the assembly, a damping mechanism is used to control the rate at which the assembly is allowed to pivot. The feature and the damping mechanism, possibly a gas type shock absorber, must be maintained in an open or extended position during the service of the machine. To achieve this, a locking device is employed that will oppose a compressive force acting along the centerline of the damping mechanism and maintain the assembly in an extended position.

Referring to Figure 1, the locking mechanism consists of a brace 1 and a leaf spring 2, connected by shoulder rivet 4. The mechanism is designed to provide a rigid stop, brace 1, between the assembly casting 7 and the shoulder of shock absorber 5. The locking mechanism is engaged, when the shock absorber shaft 6 is fully extended by applying pressure on the top of leaf spring 2 in the direction shown by arrow 3. This action will cause end 10 of brace 1 to engage the shoulder of shock absorber 5 when the assembly is placed in compression. The opposite end 8 of brace 1 contacts casting 7 to prevent further compression of the s...
