Abstract

A band saw includes a first wheel and a second wheel for supporting a continuous band saw blade, a motor operable to drive at least one of the first and second wheels, a housing supporting the first wheel and the second wheel, a shoe for engaging a workpiece, the shoe including a first detent feature. The band saw also includes a second detent feature cooperating with the first detent feature to hold the shoe with respect to the housing. The shoe is moveable with respect to the housing between an engaged position and a non-engaged position. The shoe is moveable out of the engaged position by application of a force acting to move the shoe with respect to the housing sufficient to overcome cooperation between the first and second detent features in the engaged position.

First claim

What is claimed is:

1. A band saw comprising:
a first wheel and a second wheel for supporting a continuous band saw blade;
a motor operable to drive at least one of the first and second wheels;
a housing supporting the first wheel and the second wheel;
a shoe for engaging a workpiece, the shoe including a first detent feature; and
a second detent feature cooperating with the first detent feature to hold the shoe with respect to the housing;
wherein the shoe is moveable in a direction with respect to the housing between an engaged position in which the first and second detent features cooperate to hold the shoe with respect to the housing, and a non-engaged position in which the shoe is movable;
wherein the shoe is moveable out of the engaged position by application of a force acting on the shoe and acting substantially in the direction to move the shoe with respect to the housing, and acting to overcome cooperation between the first and second detent features in the engaged position.

2. The band saw of claim 1 , wherein the shoe is moveable out of the engaged position by application of the force directly on the shoe sufficient to overcome cooperation between the first and second detent features in the engaged position and cause the shoe to move relative to the housing.

3. The band saw of claim 1 , wherein at least one of the detent features includes a biasing member providing a biasing force acting to hold the shoe with respect to the housing in the engaged position, wherein application of the force on the shoe acts to compress the biasing member and cause the shoe to move relative to the housing when the force is sufficient to overcome the biasing force.

4. The band saw of claim 1 , further comprising first and second outwardly extending flanges, wherein the shoe includes a generally C-shaped member wrapped around and slideably engaging the first and second flanges.

5. The band saw of claim 4 , wherein the first and second outwardly extending flanges extend from a main portion such that the first and second outwardly extending flanges and the main portion together form a generally T-shaped cross section received by the generally C-shaped member.

6. The band saw of claim 1 , wherein the second detent feature includes a biasing member and a ball biased in a first direction by the biasing member, and the first detent feature includes a first aperture in the shoe for receiving the ball to hold the shoe with respect to the housing in the engaged position.

7. The band saw of claim 6 , wherein the engaged position is a first engaged position, and wherein the shoe further includes a second aperture for receiving the ball to hold the shoe with respect to the housing in a second engaged position.

8. The band saw of claim 6 , wherein the biasing member includes a leaf spring.

9. The band saw of claim 6 , wherein the biasing member biases the ball toward the shoe.

10. The band saw of claim 1 , wherein the non-engaged position includes a removed position in which the shoe is disengaged from the housing such that the shoe is removable.

11. The band saw of claim 1 , wherein the shoe is moveable between a plurality of engaged positions.

12. The band saw of claim 1 , wherein at least one of the detent features includes a biasing member that compresses as the shoe moves from the engaged position to the non-engaged position.

13. A band saw comprising:
a housing supporting a motor operable to drive a continuous band saw blade to cut a workpiece, the housing having a first portion and a second portion;
a cavity between the first portion and the second portion for receiving the continuous band saw blade and accommodating a workpiece during a cutting operation; and
a shoe assembly coupled adjacent the cavity to the first portion of the housing, the shoe assembly comprising,
a first detent feature,
a body having a surface for engaging a workpiece, and
a second detent feature for cooperating with the first detent feature to hold the body with respect to the housing,
wherein the body is moveable in a direction with respect to the housing between an engaged position in which the first and second detent features cooperate to hold the body with respect to the housing, and a non-engaged position in which the body is movable;

wherein the body is moveable out of the engaged position by application of a force acting on the body and acting substantially in the direction to move the body with respect to the housing, and acting to overcome cooperation between the first and second detent features in the engaged position.

14. The band saw of claim 13 , wherein at least one of the detent features includes a biasing member configured to compress as the shoe moves from the engaged position to the non-engaged position.

15. The band saw of claim 13 , wherein the body is moveable out of the engaged position by application of the force directly on the body of a magnitude_sufficient to overcome cooperation between the first and second detent features in the engaged position and cause the body to move relative to the housing.

16. The band saw of claim 13 , wherein at least one of the detent features includes a biasing member providing a biasing force acting to hold the body with respect to the housing in the engaged position, wherein application of the force on the body acts to move the at least one of the detent features in a direction away from the body and cause the body to move relative to the housing when the force is of a magnitude sufficient to overcome the biasing force.

17. The band saw of claim 13 , wherein first and second outwardly extending flanges extend from the housing, and wherein the body includes a generally C-shaped member wrapped around and slideably engaging the first and second flanges.

18. The band saw of claim 17 , wherein the first and second outwardly extending flanges extend from a main portion such that the first and second outwardly extending flanges and the main portion together form a generally T-shaped cross section received by the generally C-shaped member.
