Abstract
Abstract The aligning or jack device is used for leveling or squaring a wooden wall section that is formed of floor and ceiling plates interconnected by studs and including a brace member loosely attached to diagonally opposite portions of the section. The device includes a pair of clamp assemblies, one for embracing the floor plate and the second one for embracing the brace member. The second clamp assembly is movably mounted on a handle or lever member that has one end pivoted on the first clamp assembly for pivoted movement about a horizontal axis. On actuation of the lever the studs and plates are relatively moved by the brace member to positions extended normal to each other, and are retained in such positions by rigidly securing the brace member to the wooden section.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
239 words
A jack device for squaring a wooden wall section having floor and ceiling plates interconnected by stud members and a brace member loosely attached to diagonally opposite end portions of said section, said device comprising: a. an elongated lever member, b. a pair of clamp assemblies of an inverted U-shape, with a first one of said assemblies corresponding to said floor plate, and the second one of said assemblies corresponding to said brace member, each of said clamp assemblies including a pair of oppositely arranged clamp arms, c. means pivotally supporting a clamp arm of said first clamp assembly adjacent one end of said lever member for pivotal movement about an axis extended transversely of the lever member, and other means pivotally supporting the opposite arm of said first clamp assembly for pivotal movement about an axis parallel to the axis of said lever member, and d. means mounting the second clamp assembly on one clamp arm thereof for longitudinal movement relative to the lever member and for rotational movement about the axis of the lever member, e. said lever member, when the floor plate is received within the first clamp assembly and the brace member is received within the second clamp assembly, being manually pivoted relative to the first clamp assembly about said transverse axis to a position wherein the stud members and plate members of the wooden wall section are extended in planes normal to each other.
Claim 2
Dependent Claim
239 words
A jack device for squaring a wooden wall section having floor and ceiling plates interconnected by stud members and a brace member loosely attached to diagonally opposite end portions of said section, said device comprising: a. an elongated lever member, b. a pair of clamp assemblies of an inverted U-shape, with a first one of said assemblies corresponding to said floor plate, and the second one of said assemblies corresponding to said brace member, each of said clamp assemblies including a pair of oppositely arranged clamp arms, c. means pivotally supporting a clamp arm of said first clamp assembly adjacent one end of said lever member for pivotal movement about an axis extended transversely of the lever member, and other means pivotally supporting the opposite arm of said first clamp assembly for pivotal movement about an axis parallel to the axis of said lever member, and d. means mounting the second clamp assembly on one clamp arm thereof for longitudinal movement relative to the lever member and for rotational movement about the axis of the lever member, e. said lever member, when the floor plate is received within the first clamp assembly and the brace member is received within the second clamp assembly, being manually pivoted relative to the first clamp assembly about said transverse axis to a position wherein the stud members and plate members of the wooden wall section are extended in planes normal to each other.
Claim 3
Dependent Claim
189 words
A jack device for squaring a wooden wall section having floor and ceiling plates interconnected by stud members and a brace member loosely attached to diagonally opposite end portions of said section, said device comprising: a. a clamp assembly including a base member and a first clamping unit for transversely embracing the floor plate, said clamping unit comprised of a stationary clamp arm and a pivoted clamp arm, b. means pivotally supporting the pivoted clamp arm on the base member for pivotal movement about an axis projected upwardly from said base member, c. an elongated handle member pivoted at one end on said pivoted clamp arm for pivotal movement about an axis normal to the axis of said pivoted clamp arm, and d. a second clamping unit for transversely embracing said brace member mounted on said handle member for relative rotational and sliding movement, e. said handle, when the floor plate and brace member are embraced by the first clamping unit and second clamping unit, respectively, being manually operated to move said brace member to a position wherein the stud members are normal to the floor and ceiling plates.
Claim 4
Dependent Claim
