Claims
- 1. A jack comprising:
- (a) a first pipe threaded at one end thereof;
- (b) a first jaw member slidable longitudinally along said first pipe for quick positioning and having means to lock the same at any position therealong;
- (c) a mounting bracket having first and second threaded bores extending therethrough parallel to and spaced apart from one another;
- (d) a second pipe threaded at one end thereof, said first and second pipes being threaded into said first threaded bore respectively from opposite ends thereof;
- (e) a second jaw member slidable along said second pipe;
- (f) a threaded rod extending through said second threaded bore in the bracket and rotatably connected to said second jaw member to move the same during rotation of the threaded rod, said threaded rod being axially parallel with said pipes; and
- (g) handle means swingingly connected at one end thereof to one end of said threaded rod for rotating the same, said first and second jaw member each having an article engaging face and wherein said faces are directed away from one another.
- 2. A jack as defined in claim 1 wherein each of said first and second threaded bores are provided by sleeves having internal threaded molded therein and wherein said sleeves are press fit into recesses in said bracket.
- 3. A jack as defined in claim 1 wherein said handle has at least one formation thereof adapted for engagement by a wrench to turn the handle.
- 4. A jack as defined in claim 2 including means on said sleeves engaging said bracket to prevent rotation of the sleeves in their respective recesses in the bracket.
- 5. A jack as defined in claim 4 including means preventing axial displacement of the sleeves in their respective recesses in the bracket.
- 6. A jack as defined in claim 5 wherein one of said sleeves is prevented against axial displacement in one direction and wherein the other of said sleeves is prevented against axial displacement in an opposite direction.
- 7. A jack comprising:
- (a) a first pipe threaded at one end thereof;
- (b) a first jaw member slidable longitudinally along said first pipe for quick positioning and having means to lock the same at any position therealong;
- (c) a mounting bracket having first and second internal threaded portions of standard pipe thread tapped on a common centerline from opposite faces of said bracket and a further threaded bore parallel to said common centerline and spaced from said first and second portions;
- (d) a second pipe threaded at one end thereof, said first and second pipes being threaded into respective ones of said first and second axially aligned threaded portions of said bracket;
- (e) a second jaw member slidable along said second pipe;
- (f) a threaded rod extending through said further threaded bore in said bracket and rotatbly connected to said second jaw member to move the same during rotation of the threaded rod, said threaded rod being axially parallel with said pipes; and
- (g) handle means swingingly connected at one end thereof to one end of said threaded rod for rotating the same, said first and second jaw members each having an article engaging face and wherein said faces are directed away from one another.
