Abstract
Abstract A spacing tool provides for the positive holding and spacing of structural members, such as 2×4s, that is simple and easy to use and positively holds the structural members in place for nailing or fastening, while straightening any bows or twists therein. First and second jaw assemblies each include a pair of jaws extending from a first end thereof, the jaws of each pair being spaced from each other a fixed distance. A locking lever is disposed between the jaw assemblies second ends, and is pivotally mounted to the jaw assemblies to move them from a second, unlocked position wherein they are not in-line and the jaws are not spaced from each other a fixed, predetermined distance, to a first, locked position where they are substantially in-line and overlap and the jaws are spaced from each other a fixed predetermined distance to space structural members.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
265 words
A tool for holding and spacing structural members, comprising: a first jaw assembly including a linear body portion elongated in a predetermined dimension and a pair of stationary first jaws spaced from each other a fixed predetermined distance and extending parallel to each other in the same direction from a first end of said body portion, said direction substantially perpendicular to said dimension of elongation; a second jaw assembly including a linear body portion elongated in a predetermined dimension and a pair of stationary second jaws spaced from each other a fixed predetermined distance and extending parallel to each other in the same direction from a first end of said body portion, said direction substantially perpendicular to said dimension of elongation; a locking lever comprising a handle and a body; cooperating surface means formed on second ends of said jaw assemblies, opposite said first ends, for providing overlap between said first and second jaw assembly body portions in the dimension of elongation thereof; and means for pivotally mounting said locking lever body to said first and second jaw assemblies body portions at spaced points adjacent the second ends thereof, so that the jaw assemblies are movable from a first, locked, substantially in-line position, with said locking lever body therebetween and said handle extending outwardly with said first and second jaws spaced from each other a fixed predetermined distance; to a second, unlocked, position wherein said jaw assemblies do not overlap and said jaw assembly body portions are not in-line, and said first and second jaws are not spaced a fixed, predetermined position from each other.
Claim 2
Dependent Claim
265 words
A tool for holding and spacing structural members, comprising: a first jaw assembly including a linear body portion elongated in a predetermined dimension and a pair of stationary first jaws spaced from each other a fixed predetermined distance and extending parallel to each other in the same direction from a first end of said body portion, said direction substantially perpendicular to said dimension of elongation; a second jaw assembly including a linear body portion elongated in a predetermined dimension and a pair of stationary second jaws spaced from each other a fixed predetermined distance and extending parallel to each other in the same direction from a first end of said body portion, said direction substantially perpendicular to said dimension of elongation; a locking lever comprising a handle and a body; cooperating surface means formed on second ends of said jaw assemblies, opposite said first ends, for providing overlap between said first and second jaw assembly body portions in the dimension of elongation thereof; and means for pivotally mounting said locking lever body to said first and second jaw assemblies body portions at spaced points adjacent the second ends thereof, so that the jaw assemblies are movable from a first, locked, substantially in-line position, with said locking lever body therebetween and said handle extending outwardly with said first and second jaws spaced from each other a fixed predetermined distance; to a second, unlocked, position wherein said jaw assemblies do not overlap and said jaw assembly body portions are not in-line, and said first and second jaws are not spaced a fixed, predetermined position from each other.
Claim 3
Dependent Claim
56 words
A tool as recited in claim 1 wherein when said jaw assemblies are in said first, locked, position thereof, the pivotal connection of said locking lever body to said first jaw assembly body portion is closer to said second jaws than the pivotal connection of said locking lever body to said second jaw assembly body portion.
Claim 4
Dependent Claim
58 words
A tool as recited in claim 2 wherein said pivotal connections of said locking lever body to said first and second jaw assembly body portions are offset from each other in a dimension perpendicular to the dimension of elongation of said jaw assembly body portions when in said first, locked, position, so that an overcenter action is provided.
Claim 5
Dependent Claim
27 words
A tool as recited in claim 2 wherein said first and second jaws are parallel to each other and extend in the same direction as each other.
Claim 6
Dependent Claim
149 words
A tool as recited in claims 1 or 4 wherein said cooperating surface means comprise: a bifrucated second end of said first jaw assembly, having a pair of arms spaced from each other a predetermined distance; a bifrucated locking lower body portion, having a pair of arms the exteriors of which are spaced from each other a distance approximately the same as the interiors of the arms of said first jaw assembly; and a central portion of said second jaw assembly body portion, having exterior surfaces spaced from each other a distance approximately the same as the spacing of the interiors of said locking lever arms from each other; and wherein in the first, locked, position of said assemblies, said arms of said locking lever are received between said arms of said first jaw assembly, and said second jaw assembly central portion is received between said locking lever arms.
Claim 7
Dependent Claim
60 words
A tool as recited in claim 5 wherein said means for pivotally mounting said locking lever body to said first jaw assembly comprises an in-line pair of posts, one extending outwardly from each of said locking lever arms perpendicular to said arms; and a pair of in-line openings formed in said first jaw assembly arms for receipt of said posts.
Claim 8
Dependent Claim
55 words
A tool as recited in claim 6 wherein said means for pivotally mounting said locking lever body to said second jaw assembly comprises an in-line pair of through-extending openings formed in said locking lever arms, and a cooperating opening formed in said second jaw assembly central portion; and a pivot pin extending through said openings.
Claim 9
Dependent Claim
41 words
A tool as recited in claim 5 further comprising a pair of stop members fixed to said first jaw assembly and blocking off the opening between the arms thereof on a side of the arms from which said first jaws extend.
Claim 10
Dependent Claim
270 words
A tool for holding and spacing structural members, comprising: a first jaw assembly including a linear body portion elongated in a predetermined dimension and having first and second ends; a pair of stationary first jaws spaced from each other a fixed predetermined distance and extending parallel to each other in the same direction from the first end of the body portion; the second end of the body portion being bifrucated, having a pair of arms spaced from each other a predetermined distance; a locking lever comprising a handle and a body, said body being bifrucated, having a pair of arms the exteriors of which are spaced from each other a distance approximately the same as the predetermined spacing of the interiors of the arms of said first jaw assembly; a second jaw assembly including a linear body portion elongated in a predetermined dimension, and having first and second ends; a pair of stationary second jaws spaced from each other a fixed predetermined distance and extending parallel to each other in the same direction from the first end of said body portion; and said second end of said body portion having a thinned central portion having exterior surfaces spaced from each other a distance approximately the same as the spacing of the interiors of said locking lever arms; stop means closing off the space between said first jaw assembly arms on a side of said first assembly body portion from which said first jaws extend; and means for pivotally mounting said locking lever body to said first and second jaw assemblies body portions at spaced points adjacent the second ends thereof.
Claim 11
Dependent Claim
