Abstract
A rail adapter may include a mount configured to couple to the workpiece. A rail adapter may include a first arm having a first end pivotably coupled to the mount about a first pivot axis and an opposite second end. A rail adapter may include a second arm having a first end pivotably coupled to the first arm about a second pivot axis and an opposite second end. A rail adapter may include a mounting bracket pivotably coupled to the second end of the second arm and mounted to the saw. A rail adapter may include a first pivot lock engageable to inhibit a first degree of freedom of the mounting bracket and the saw. A rail adapter may include a second pivot lock engageable to inhibit a second degree of freedom of the mounting bracket and the saw, the second degree of freedom being different from the first.
Claims20
A rail adapter for supporting a saw on a workpiece, the rail adapter comprising:
- a mount configured to couple to the workpiece;
- a first arm having a first end pivotably coupled to the mount about a first pivot axis and an opposite second end;
- a second arm having a first end pivotably coupled to the first arm about a second pivot axis and an opposite second end;
- a mounting bracket pivotably coupled to the second end of the second arm and mounted to the saw;
- a first pivot lock engageable to inhibit a first degree of freedom of the mounting bracket and the saw;
- and
- a second pivot lock engageable to inhibit a second degree of freedom of the mounting bracket and the saw, the second degree of freedom being different from the first degree of freedom.
A system for cutting through railroad sections, the system comprising:
- a saw including
- a housing,
- a support arm extending from the housing,
- a cutting wheel supported at one end of the support arm, and
- a blade guard covering a portion of the cutting wheel;
- and
- a rail adapter including
- a mount configured to couple to a railroad section,
- a first arm having a first end pivotably coupled to the mount and an opposite second end,
- a second arm having a first end pivotably coupled to the first arm and an opposite second end,
- a mounting bracket pivotably coupled to the second end of the second arm and mounted to the saw, and
- a control device having a first end coupled to the first arm and a second end coupled to the second arm, the control device biasing the first arm away from the second arm to partially support the weight of the saw above the railroad section.

- a cutting wheel supported at one end of the support arm, and
- a blade guard covering a portion of the cutting wheel;
- and
- a rail adapter including
- a mount configured to couple to a railroad section,
- a first arm having a first end pivotably coupled to the mount and an opposite second end,
- a second arm having a first end pivotably coupled to the first arm and an opposite second end,
- a mounting bracket pivotably coupled to the second end of the second arm and mounted to the saw, and
- a spark plate positioned behind the cutting wheel and under the blade guard to prevent sparks from contacting a user.
