Abstract
A miter box has a housing with support means within the housing for supporting a motor. The motor drives a cutting means. The motor is pivotably disposed with respect to a vertical plane through the housing and is disposed at a desired angular relationship. The motor may be manually moved by the support means. A workpiece is supported on the top of the housing at a selected angular relationship to the cutting means. The workpiece may be miter cut and bevel cut simultaneously.
Claims15
A miter box comprising:
- a housing having a top surface and a plurality of supporting side walls forming an enclosure,
- an elongated opening being formed in the top surface of the housing near a first of the supporting side walls,
- a work-holding member having a first end, the work-holding member being connected to the top surface of the housing such that the work-holding member may be slidably moved with respect to the top surface of the housing to dispose the first end of the work holding member at a selected angle with respect to the elongated opening in the top surface of the housing,
- a plurality of spaced-apart support means disposed in the enclosure under, and approximately parallel to, the elongated opening in the top surface of the housing,
- an electrically-powered motor supported on the support means in the enclosure,
- a cutting means driven by the electrically-powered motor, the cutting means projecting upwardly into the elongated opening in the top surface of the housing, and
- means to move the electrically-powered motor with the cutting means longitudinally within the elongated opening, wherein a workpiece disposed in the work-holding member and extending over the elongated opening is cut at a predetermined angle corresponding to the selected angle of the work-holding member with respect to the elongated opening.
In a power-driven saw machine for making a miter cut, a bevel cut, or a compound miter-bevel cut in a workpiece, wherein the machine includes a housing, a motor within the housing, and a cutting means driven by the motor and projecting above the housing;
- the improvement comprising a support means within the housing for supporting the motor for movement within the housing, the motor being pivotably disposed with respect to a vertical plane through the housing and being arranged at a desired angular relationship relative to the vertical plane whenever a bevel cut of the workpiece is intended, and a rod connected to the motor and having an end portion projecting externally of the housing, such that the end portion of the rod may be manually manipulated for moving the motor along the support means within the housing for making a cut in the workpiece, the workpiece being supported on top of the housing and being arranged at an angular relationship relative to the cutting means whenever a miter cut of the workpiece is intended.
A miter box comprising:
- a housing having a top surface, an elongated opening formed in the top surface,
- at least two spaced-apart curved tracks formed on the top surface of the housing,
- a work-holding member having a bottom surface,
- at least two spaced-apart protrusions formed on the bottom surface of the work- holding means,
- each of the at least two spaced-apart protrusions being received in a respective track on the top surface of the housing,
- wherein the work-holding member may be slidably moved and guided to a selected angle with respect to the elongated opening on the top surface of the housing.
