Spring handling apparatus

Claim 2

Apparatus for effecting compression of a coil spring member comprising, in combination, a pair of jaws adapted for engagement on axially spaced coils of said coil spring member from exteriorly of the latter, pivot means disposed between said jaws adapted to support one of said jaws on the other for pivotal movement relative thereto, converging relative pivotal movement between said jaws effecting compression of the spring coils between said jaws and axial collapse of said coil spring member, a flexible and inextensible connecting member disposed between said jaws in a manner whereby tension in said connecting member effects converging relative pivotal movement between said jaws, and selectively operable control means disposed between said connecting member and one of said jaws for placing said connecting member in tension.

Claim 3

Apparatus for effecting compression of a coil spring member comprising, in combination, a pair of jaws adapted for engagement on axially spaced coils of said coil spring member from exteriorly of the latter, pivot means disposed between said jaws adapted to support one of said jaws on the other for pivotal movement relative thereto, converging relative pivotal movement between said jaws effecting compression of the spring coils between said jaws and axial collapse of said coil spring member, a flexible inextensible connecting member, means connecting one end of said connecting member to one of said jaws, an anchor, means Mounting said anchor on the other of the jaws for bodily shiftable movement, and means connecting the other end of said connecting member to said anchor so that bodily shiftable movement of the latter in one direction effects converging pivotal movement between said jaws through tension in said flexible connecting member.

Claim 4

Apparatus for effecting compression of a coil spring member comprising, in combination, a pair of jaws adapted for engagement on axially spaced coils of said coil spring member from exteriorly of the latter, pivot means disposed between said jaws adapted to support one of said jaws on the other for pivotal movement relative thereto, converging relative pivotal movement between said jaws effecting compression of the spring coils between said jaws and axial collapse of said coil spring member, a flexible inextensible connecting member, means connecting one end of said connecting member to one of said jaws, an anchor, means Mounting said anchor on the other of the jaws for bodily shiftable movement, and means connecting the other end of said connecting member to said anchor so that bodily shiftable movement of the latter in one direction effects converging pivotal movement between said jaws through tension in said flexible connecting member.

Claim 5

Apparatus as recited in claim 2 further including selectively operable control means associated with said anchor for effecting selective bodily shiftable movement of the latter.

Claim 6

Apparatus for effecting compression of a coil spring member comprising, in combination, a pair of jaws adapted to engage axially spaced coils of said coil spring member from exteriorly of the latter, pivot means disposed between said jaws adapted to support one of said jaws on the other for pivotal movement relative thereto, converging relative pivotal movement between said jaws being operative to effect compression of the spring coils between said jaws and axial collapse of said coil spring member, a flexible inextensible connecting member, means connecting one end of said connecting member to said one jaw, a pulley rotatably supported on said other jaw, said connecting member being trained over said pulley so that a tensible force on the other end of said connecting member effects converging relative pivotal movement between said one jaw and said other jaw, an anchor, means mounting said anchor on said other jaw for bodily shiftable movement relative to the latter a screw and nut actuator assembly including a screw portion rotatably disposed on said other jaw and a nut portion rigidly attached to said anchor, relative rotation between said screw said nut portions effecting bodily shiftable movement of said anchor, and manual control means associated with said screw portion adapted to effect selective rotation thereof thereby to shift said anchor in a manner placing said connecting member in tension.

Claim 7

Apparatus for effecting compression of a coil spring member comprising, in combination, a pair of jaws adapted to engage axially spaced coils of said coil spring member from exteriorly of the latter, pivot means disposed between said jaws adapted to support one of said jaws on the other for pivotal movement relative thereto, converging relative pivotal movement between said jaws being operative to effect compression of the spring coils between said jaws and axial collapse of said coil spring member, a flexible inextensible connecting member, means connecting one end of said connecting member to said one jaw, a pulley rotatably supported on said other jaw, said connecting member being trained over said pulley so that a tensible force on the other end of said connecting member effects converging relative pivotal movement between said one jaw and said other jaw, an anchor, means mounting said anchor on said other jaw for bodily shiftable movement relative to the latter a screw and nut actuator assembly including a screw portion rotatably disposed on said other jaw and a nut portion rigidly attached to said anchor, relative rotation between said screw said nut portions effecting bodily shiftable movement of said anchor, and manual control means associated with said screw portion adapted to effect selective rotation thereof thereby to shift said anchor in a manner placing said connecting member in tension.
