Abstract
Abstract An apparatus for compressing a spring in conjunction with a shock absorber or other similar structure wherein the apparatus includes a frame upon which a spring to be compressed is mounted. An upper yoke member is slidably mounted in the frame and is operatively connected to a power sourc whereby a bracket is in position to act with source yoke member to contact a spring being compressed. Downward movement of the yoke causes compression of the spring in a manner that any desired service or operation can be performed on the spring assembly being compressed. The frame further includes a safety mechanism to insure that the spring is safely compressed during service.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
157 words
A spring compresssor apparatus for compressing the spring of a spring assembly comprising a frame means for detachably supporting a spring assembly having a spring to be compressed, said frame means including a base member adapted to contact an end of the spring to be compressed, force applying means slidably mounted on said frame means and adapted to apply a force adjacent the other end of the spring to be compressed; said force applying means including a pusher plate having a cutout portion adapted to receive a spring to be compressed, power actuation means operatively coupled to said force applying means and adapted to apply a compressive force to the spring to be compressed, and said force applying means further including a removable bracket having spaced surfaces on one face to contact spaced portions of the spring to be compressed and another surface on the opposite face to contact the pusher plate during application of a force.
Claim 2
Dependent Claim
157 words
A spring compresssor apparatus for compressing the spring of a spring assembly comprising a frame means for detachably supporting a spring assembly having a spring to be compressed, said frame means including a base member adapted to contact an end of the spring to be compressed, force applying means slidably mounted on said frame means and adapted to apply a force adjacent the other end of the spring to be compressed; said force applying means including a pusher plate having a cutout portion adapted to receive a spring to be compressed, power actuation means operatively coupled to said force applying means and adapted to apply a compressive force to the spring to be compressed, and said force applying means further including a removable bracket having spaced surfaces on one face to contact spaced portions of the spring to be compressed and another surface on the opposite face to contact the pusher plate during application of a force.
Claim 3
Dependent Claim
26 words
The spring compressor apparatus of claim 1 wherein said frame means includes a vertically extending U-shaped frame adapted to vertically support the spring to be compressed.
Claim 4
Dependent Claim
23 words
The spring compressor apparatus of claim 2 wherein said force applying means is slidably mounted in a vertically disposed slot on said frame.
Claim 5
Dependent Claim
29 words
The spring compressor apparatus of claim 1 wherein the force applying means applies a compressive force in a direction along the longitudinal centerliNe of the spring to be compressed.
Claim 6
Dependent Claim
43 words
The spring compressor apparatus of claim 1 wherein the frame means includes a plurality of openings adapted to receive a pin member and a pin member for selective insertion in the openings to prevent movement of the force applying means past the pin.
Claim 7
Dependent Claim
35 words
The spring compressor of claim 1 further including safety means slidably mounted on the frame means beneath the force applying means and adapted to retain the spring being compressed during application of a compressive force.
Claim 8
Dependent Claim
38 words
The spring compressor of claim 1 further including projection means positioned on the pusher plate to contact the removable bracket for retaining the bracket in position in contact with the pusher plate during application of a compressive force.
Claim 9
Dependent Claim
17 words
The spring compressor of claim 1 wherein the spaced surfaces of the bracket lie in spaced planes.
Claim 10
Dependent Claim
139 words
A spring compressor apparatus for compressing the spring of a spring assembly comprising a frame means for detachably supporting a spring assembly having a spring to be compressed, said frame means including a base member adapted to contact an end of the spring to be compressed, force applying means slidably mounted on said frame means and adapted to apply a force adjacent the other end of the spring to be compressed, power actuation means operatively coupled to said force applying means and adapted to apply a compressive force to the spring to be compressed, safety means slidably mounted on the frame means beneath the force applying means and adapted to retain the spring being compressed during the application of a compressive force, and the safety means includes a hook member for hooking a portion of the spring being compressed.
Claim 11
Dependent Claim
139 words
A spring compressor apparatus for compressing the spring of a spring assembly comprising a frame means for detachably supporting a spring assembly having a spring to be compressed, said frame means including a base member adapted to contact an end of the spring to be compressed, force applying means slidably mounted on said frame means and adapted to apply a force adjacent the other end of the spring to be compressed, power actuation means operatively coupled to said force applying means and adapted to apply a compressive force to the spring to be compressed, safety means slidably mounted on the frame means beneath the force applying means and adapted to retain the spring being compressed during the application of a compressive force, and the safety means includes a hook member for hooking a portion of the spring being compressed.
Claim 12
Dependent Claim
21 words
The spring compressor of claim 9 wherein the hook member contacts a portion of the bottom of the spring being compressed.
Claim 13
Dependent Claim
29 words
The spring compressor of claim 10 wherein the frame means includes track means for slidably guiding the safety means in the direction of movement of the force applying means.
Claim 14
Dependent Claim
23 words
The spring compressor of claim 11 wherein the safety means includes a pair of sandwiched plate members for support for the hook member.
