Abstract
Abstract A tool for holding and positioning an electrical junction box includes a pair of handles pivotally connected in a lever arrangement so that squeezing together the grip portions of the handles urges apart the jaw portions of the handles. A spring biases the jaw portions together. A first jaw portion has a flat surface for contacting an outside of a wall electrical junction box. A second jaw portion has two spaced apart fingers for contacting an inside surface of the wall of the junction box so that the jaw portions grip the wall in a three-point connection. The first jaw portion has a sliding adjustable plate for contacting the face of a wall stud or ceiling joist to set the distance from that face that the front edge of the wall of the junction box will be positioned.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
296 words
A tool for positioning an electrical box for attachment to a building framing member comprising: a first jaw element including a plate for contacting a first of the outside and inside surfaces of a wall of an electrical box; a second jaw element having two spaced-apart fingers for contacting the second of the outside and inside surfaces of the wall of the electrical box; means to bias the first and second jaw elements together to grip the wall of the box between the plate and the two fingers; a stop means mounted on one jaw element for contacting a facing edge of the wall of the electrical box; a spacer plate on one jaw element for contacting a face of a building framing member to determine the relative position of the face of the framing member and the facing edge of the wall of the box when the wall of the box is positioned adjacent a side of the framing member; adjustment means for adjusting the position of the spacer plate relative to the stop means, thereby varying the relative position of the facing edge of the wall of the box and the face of the framing member; wherein the jaw element carrying the spacer plate has a first surface; wherein the spacer plate has a leg with a second surface extending generally parallel to and in sliding contact with the first surface of the jaw element; wherein the adjustment means includes protruberances on one surface and corresponding recesses on the other surface, the protruberances engaging the recesses in a finite number of fixed positions; and the adjustment means further including a threaded bolt mounted through the leg and threadably engaged with the jaw element to tighten the two surfaces in close contact with each other.

A tool for positioning an electrical box for attachment to a building framing member comprising: a first jaw element including a plate for contacting a first of the outside and inside surfaces of a wall of an electrical box; a second jaw element having two spaced-apart fingers for contacting the second of the outside and inside surfaces of the wall of the electrical box; means to bias the first and second jaw elements together to grip the wall of the box between the plate and the two fingers; a stop means mounted on one jaw element for contacting a facing edge of the wall of the electrical box; a spacer plate on one jaw element for contacting a face of a building framing member to determine the relative position of the face of the framing member and the facing edge of the wall of the box when the wall of the box is positioned adjacent a side of the framing member; adjustment means for adjusting the position of the spacer plate relative to the stop means, thereby varying the relative position of the facing edge of the wall of the box and the face of the framing member; wherein the jaw element carrying the spacer plate has a first surface; wherein the spacer plate has a leg with a second surface extending generally parallel to and in sliding contact with the first surface of the jaw element; wherein the adjustment means includes protruberances on one surface and corresponding recesses on the other surface, the protruberances engaging the recesses in a finite number of fixed positions; and the adjustment means further including a threaded bolt mounted through the leg and threadably engaged with the jaw element to tighten the two surfaces in close contact with each other.
Claim 3
Dependent Claim
36 words
The tool of claim 1 wherein: the recesses include a row of holes generally perpendicular to the spacer plate; and the protuberances include a pair of pins positioned to fit in various pairs of the holes.
Claim 4
Dependent Claim
210 words
A tool for positioning an electrical box for attachment to a building wall stud further comprising: a first jaw element including a plate for contacting a first of the outside and inside surfaces of a wall of an electrical box; a second jaw element having two spaced-apart fingers for contacting the second of the outside and inside surfaces of the wall of the electrical box; means to bias the first and second jaw elements together to grip the wall of the box between the plate and the two fingers; a stop means mounted on one jaw element for contacting a facing edge of the wall of the electrical box; a spacer plate on one jaw element for contacting a building wall stud to determine the relative position of the face of the wall stud to determine the relative position of the face of the wall stud and the facing edge of the wall of the box when the wall of the box is positioned adjacent a side of the wall stud; wherein a clip is mounted on one jaw element for receiving and holding a measuring rod for contacting the floor to determine a distance from the floor that the electrical box is to be attached to the wall stud.
Claim 5
Dependent Claim
210 words
A tool for positioning an electrical box for attachment to a building wall stud further comprising: a first jaw element including a plate for contacting a first of the outside and inside surfaces of a wall of an electrical box; a second jaw element having two spaced-apart fingers for contacting the second of the outside and inside surfaces of the wall of the electrical box; means to bias the first and second jaw elements together to grip the wall of the box between the plate and the two fingers; a stop means mounted on one jaw element for contacting a facing edge of the wall of the electrical box; a spacer plate on one jaw element for contacting a building wall stud to determine the relative position of the face of the wall stud to determine the relative position of the face of the wall stud and the facing edge of the wall of the box when the wall of the box is positioned adjacent a side of the wall stud; wherein a clip is mounted on one jaw element for receiving and holding a measuring rod for contacting the floor to determine a distance from the floor that the electrical box is to be attached to the wall stud.
Claim 6
Dependent Claim
38 words
The tool of claim 3 wherein the clip is a resilient generally U-shaped clip attached to the jaw element at the base of the U with a hole in each leg of the U for receiving the rod.
Claim 7
Dependent Claim
215 words
A tool for positioning an electrical box for attachment to a building framing member comprising: a first jaw element including a plate for contacting a first of the outside and inside surfaces of a wall of an electrical box; a second jaw element having two spaced-apart fingers for contacting the second of the outside and inside surfaces of the wall of the electrical box; means to bias the first and second jaw elements together to grip the wall of the box between the plate and the two fingers; a stop means mounted on one jaw element for contacting a facing edge of the wall of the electrical box; a spacer plate on one jaw element for contacting a face of a building framing member to determine the relative position of the face of the framing member and the facing edge of the wall of the box when the wall of the box is positioned adjacent a side of the framing member; wherein each finger comprises a sheet aligned generally perpendicular to the spacer plate so that an edge of that sheet contacts the inside surface of the wall of the electrical box; and wherein the edge of the sheet is rounded in the plane of the sheet to minimize area of contact with the wall.
