Abstract
This invention provides a tool and a method of using the tool to spread linearly spaced objects apart. The tool is positioned between the spaced objects and then operated by mechanical action to generate compressive forces which act against the spaced objects to cause the linear separation between the objects to increase. The objects to be separated can be horizontally or vertically spaced and each can be movable or one can be stationary and the other can be movable.
Claims12
An apparatus for increasing the linear separation between a first object and a second object:
- said apparatus is an elongated structure comprising a first end member, a second end member, a linear pressure transmission member and a force generating member;
- said first end member is comprised of at least one linear tubular member having a hollow interior, a primary distal end and a primary proximal end, wherein said primary distal end of said first end member is adapted to contact and transmit compressive force to said first object;
- said second end member is comprised of a traveling housing having a hollow interior, a first distal end adapted to contact and transmit compressive force to said second object and a flanged first proximal end adapted to slidably contain said linear pressure transmission member;
- said linear pressure transmission member is positioned intermediate said first end member and said second end member and is comprised of a solid threaded rod having a free end and a fixed end, wherein said fixed end of said linear pressure transmission member is rigidly connected to said primary proximal end of said first end member to prevent motion between said first end member and said linear pressure transmission member and to enable said linear pressure transmission member to transmit compressive force to said first end member, and said free end of said linear pressure transmission member is positioned in linear slidable relation in said hollow interior of said second end member;
- said force generating member has a top surface and a bottom surface and is rotationally connected to said linear pressure transmission member intermediate said first end member and said second end member to enable simultaneous linear and rotational motion of said force generating member relative to said linear pressure transmission member, said top surface of said force generating member is adapted to permit rotational contact against said flanged proximal end of said second end member to enable said force generating member to transmit compressive force to said second end member.

An apparatus for increasing the linear separation between a first object and a second object:
- said apparatus is an elongated structure comprised of a hollow traveling housing having a first distal end and a first flanged proximal end, a tubular member having a second distal end and a second proximal end, a threaded rod having a free end and a fixed end, and a nut having threads compatible with said threaded rod;
- said threaded rod is positioned intermediate said hollow traveling housing and said tubular member wherein said fixed end of said threaded rod is rigidly connected to said second proximal end of said tubular member to thereby enable said threaded member to transmit compressive force to said tubular member, and said free end of said threaded rod is slidably inserted into said first flanged proximal end of said hollow traveling housing;
- said nut is threaded on said threaded rod intermediate said hollow traveling housing and said tubular member and said nut is adapted to contact and rotate against said first flanged proximal end of said hollow traveling housing to thereby permit said nut to transmit compressive force against said hollow traveling housing.
