Abstract

A shoe for a band saw, the shoe having a body including a generally C-shaped member defined by a substantially planar portion for engaging a workpiece and a pair of rails extending transversely therefrom and wrapping such that the body includes a generally T-shaped receptacle for slidably receiving a correspondingly-shaped member. The substantially planar portion includes apertures aligned linearly. A biased detent feature has a holding force with a magnitude sufficient to hold the body when the detent feature is seated in one of the apertures. The body is moveable linearly, relative to the detent feature, in the direction of alignment of the apertures between engaged and non-engaged positions. The body is moveable out of the engaged position in the direction by application of a disengaging force in the direction acting to move the body with respect to the detent feature and acting to overcome the holding force in the engaged position.

First claim

What is claimed is:

1. A shoe for a band saw, the shoe comprising:
a body having a substantially planar surface for engaging a workpiece, and a plurality of apertures aligned linearly along the substantially planar surface, the body defining a generally C-shaped member having a generally C-shaped cross-section in a plane substantially perpendicular to the substantially planar surface, the generally C-shaped member defining in the plane a generally T-shaped receptacle for slidably receiving a correspondingly-shaped member; and
a biased detent feature having a holding force with a magnitude sufficient to hold the body when the detent feature is seated in one of the plurality of apertures;
wherein the generally C-shaped member includes a pair of rails extending substantially parallel to a direction of alignment of the plurality of apertures for constraining the movability of the body to a linear path;
wherein the body is moveable linearly in the direction of alignment of the plurality of apertures between an engaged position in which the body is held with the holding force of the detent feature, and a non-engaged position in which the body is movable with respect to the detent feature; and
wherein the body is moveable out of the engaged position in the direction by application of a disengaging force in the direction acting to move the body with respect to the detent feature and acting to overcome the holding force in the engaged position.

2. The shoe of claim 1 , wherein the body is movable out of the engaged position when the biased detent feature is compressed by the application of the disengaging force.

3. The shoe of claim 1 , wherein the body is not movable laterally with respect to the linear path.

4. The shoe of claim 1 , wherein the body includes an open-ended slot through the substantially planar surface for receiving a band saw blade, wherein the open-ended slot is elongated substantially parallel to the direction of alignment of the plurality of apertures.

5. The shoe of claim 1 , wherein the holding force of the detent feature is sufficient to hold the body against linear movement while a workpiece engages the substantially planar surface during a cutting operation of the band saw.

6. The shoe of claim 1 , wherein the biased detent feature includes a ball biased by a biasing member toward the body.

7. A shoe for a band saw, the shoe comprising:
a body including a generally C-shaped member defined by a substantially planar portion for engaging a workpiece and a pair of rails extending transverse to the substantially planar portion and wrapping such that the body includes a generally T-shaped receptacle defined by the substantially planar portion and the pair of rails for slidably receiving a correspondingly-shaped member, wherein the substantially planar portion includes a plurality of apertures aligned linearly; and
a biased detent feature having a holding force with a magnitude sufficient to hold the body when the detent feature is seated in one of the plurality of apertures;
wherein the body is moveable linearly, relative to the detent feature, in the direction of alignment of the plurality of apertures between an engaged position in which the body is held with the holding force of the detent feature, and a non-engaged position in which the body is movable with respect to the detent feature; and
wherein the body is moveable out of the engaged position in the direction by application of a disengaging force in the direction acting to move the body with respect to the detent feature and acting to overcome the holding force in the engaged position.

8. The shoe of claim 7 , wherein the holding force of the detent feature is sufficient to hold the body relative to the detent feature while a workpiece engages the substantially planar portion during a cutting operation of the band saw.

9. The shoe of claim 7 , wherein the body is movable out of the engaged position when the biased detent feature is compressed by the application of the disengaging force.

10. The shoe of claim 7 , wherein the body is not movable laterally with respect to the direction.

11. The shoe of claim 7 , wherein the body includes an open-ended slot through the substantially planar portion for receiving a band saw blade, wherein the open-ended slot is elongated substantially parallel to the direction of alignment of the plurality of apertures.

12. The shoe of claim 7 , wherein the biased detent feature includes a ball biased by a biasing member toward the body.

13. A shoe kit for a band saw, the shoe kit comprising:
a body including a generally C-shaped member defined by a substantially planar portion for engaging a workpiece and a pair of rails extending transverse to the substantially planar portion and wrapping such that the body includes a generally T-shaped receptacle defined by the substantially planar portion and the pair of rails of the generally C-shaped member, wherein the substantially planar portion includes at least one aperture;
a block configured to be coupled to the band saw, the block defining a generally T-shaped member correspondingly shaped with the generally T-shaped receptacle, wherein the body is configured to slide relative to the generally T-shaped member in a linear direction; and
a biased detent feature having a holding force with a magnitude sufficient to hold the body relative to the block when the detent feature is seated in the at least one aperture;
wherein the body is slideable in the linear direction with respect to the generally T-shaped member between an engaged position in which the body is held relative to the block with the holding force of the detent feature, and a non-engaged position in which the body is movable with respect to the block.

14. The shoe kit of claim 13 , wherein the holding force of the detent feature is sufficient to hold the body relative to the block while a workpiece engages the substantially planar portion during a cutting operation of the band saw.

15. The shoe kit of claim 13 , wherein the at least one aperture includes a plurality of apertures aligned linearly in the linear direction.

16. The shoe kit of claim 13 , wherein the body is moveable out of the engaged position in the direction by application of a disengaging force in the direction acting to move the body with respect to the detent feature and acting to overcome the holding force in the engaged position.

17. The shoe kit of claim 13 , wherein the block includes first and second flanges extending outwardly from a main body portion to define the generally T-shaped member.

18. The shoe kit of claim 17 , wherein the substantially planar portion and the pair of rails wrap around from a first side of the first and second flanges to a second side of the first and second flanges for constraining the body to be slideable in the linear direction with respect to the block.

19. The shoe kit of claim 13 , further comprising fasteners for coupling the block to the band saw.

20. The shoe kit of claim 13 , wherein the biased detent feature includes a ball biased by a biasing member toward the body.
