## CPC

- B27B 27/02: arranged laterally and parallel with respect to the plane of the saw blade
- B27B: SAWS FOR WOOD OR SIMILAR MATERIAL; COMPONENTS OR ACCESSORIES THEREFOR (saws specially adapted for pruning or debranching A01G3/08; sawing apparatus specially adapted for felling trees A01G23/091; features not restricted to a particular type of wood saw B23D, e.g. attaching saw blades B23D51/00; machine tool frames, beds, pillars or like members, in general B23Q1/01)

## Abstract

A reversible jig assembly for removing and replacing a portion of a trim board affixed to a substrate, comprising a first guide coupled to a first jig member; a second guide coupled to a second jig member, wherein the first guide and the second guide define a cutting channel for receiving a cutting blade, and wherein the first jig member and the second jig member are configured to define a first contact surface opposite a second contact surface; a first alignment rail extending a predetermined distance above and perpendicular to the first contact surface; and a second alignment rail extending a predetermined distance above and perpendicular to the second contact surface.

## Claims

### Claim 1

A jig assembly, comprising:
(a) a first guide coupled to a first jig member;
(b) a second guide coupled to a second jig member, wherein the first guide and the second guide are configured to define a channel, wherein the first jig member and the second jig member are configured to define a first contact surface opposite a second contact surface, and wherein the first contact surface and the second contact surface each engage a portion of a trim board affixed to a substrate;
(c) a first alignment rail extending a predetermined distance above and perpendicular to the first contact surface; and
(d) a second alignment rail extending a predetermined distance above and perpendicular to the second contact surface.

### Claim 2 (depends on 1)

The jig assembly of claim 1, wherein the channel is a through-cut channel adapted to receive the blade of a cutting device.

### Claim 3 (depends on 1)

The jig assembly of claim 1, wherein the first and second guides define a channel having a predetermined cutting angle.

### Claim 4 (depends on 3)

The jig assembly of claim 3, wherein the predetermined cutting angle is oriented upward at 30 degrees.

### Claim 5 (depends on 3)

The jig assembly of claim 3, wherein the jig assembly is reversible such that the first contact surface and the second contact surface can each engage a portion of a trim board affixed to a substrate; and the predetermined cutting angle of the channel is maintained upward at 30 degrees.

### Claim 6 (depends on 5)

The jig assembly of claim 5, wherein the jig assembly is operative to remove and replace the portion of a trim board while the trim board remains affixed to the substrate.

### Claim 7 (depends on 1)

The jig assembly of claim 1, wherein the first alignment rail and the second alignment rail each include a plurality of recessed attachment devices that couple the first alignment rail and the second alignment rail to the first jig member and the second jig member respectively.

### Claim 8 (depends on 1)

The jig assembly of claim 1, further comprising a plurality of mounting holes formed in the first and second contact surfaces, wherein each mounting hole in the plurality of mounting holes is adapted to receive a mounting screw for attaching the jig assembly to a surface.

### Claim 9

A reversible jig assembly for removing and replacing a portion of a trim board affixed to a substrate, comprising:
(a) a first guide coupled to a first jig member;
(b) a second guide coupled to a second jig member, wherein the first guide and the second guide are configured to define a through-cut channel that receives a blade, wherein the first jig member and the second jig member are configured to define a first contact surface opposite a second contact surface, and wherein the first contact surface and the second contact surface each engage a portion of a trim board affixed to a substrate;
(c) a first alignment rail extending a predetermined distance above and perpendicular to the first contact surface; and
(d) a second alignment rail extending a predetermined distance above and perpendicular the second contact surface.

### Claim 10 (depends on 9)

The jig assembly of claim 9, wherein the first and second guides define a through-cut channel having a predetermined cutting angle.

### Claim 11 (depends on 10)

The jig assembly of claim 10, wherein the predetermined cutting angle is oriented upward at 30 degrees relative to the trim board, and wherein the predetermined cutting angle of the through-cut channel is maintained upward at 30 degrees when the jig assembly is reversed.

### Claim 12 (depends on 9)

The jig assembly of claim 9, wherein the first alignment rail and the second alignment rail each include a plurality of recessed attachment devices that couple the first alignment rail and the second alignment rail to the first jig member and the second jig member respectively.
