Abstract
A tapered reamer is disclosed. The reamer is used to make a tapered opening in a cylinder used in a crossing gate repair kit. A straight reamer is also disclosed.
Claims3
A reamer for making a tapered hole comprising:
- a) a conical body having a longitudinal axis, and a threaded opening along the longitudinal axis,
- b) a plurality of cutter slots spaced from each other about the longitudinal axis,
- c) cutter bits positioned in the cutter slots,
- d) a pilot end attached to the conical body,
- e) recesses in the pilot end which receive ends of the cutter bits and maintain the cutter bits in position,
- f) an arbor end having a centered opening for the insertion of an arbor,
- g) an arbor having a threaded end for insertion of the arbor.
- h) a flange on the arbor, the flange having an outer diameter larger than the centered opening to hold the arbor in place when the threaded end of the arbor is screwed into the threaded opening of the conical body,
- i) recesses in the arbor end to receive ends of the cutter bits and maintain the cutter bits in position.

A method of making a tool for repairing a crossing gate comprising:
- a) cutting a cylindrical hole in a cylinder, the hole having a diameter slightly larger than the diameter of a pilot end of a reamer,
- b) reaming a conical opening in the cylinder with a reamer comprising:
- c) a conical body having a longitudinal axis, and a threaded opening along the longitudinal axis,
- d) a plurality of cutter slots spaced from each other about the longitudinal axis,
- e) cutter bits positioned in the cutter slots,
- f) a pilot end attached to the conical body,
- g) recesses in the pilot end which receive ends of the cutter bits and maintain the cutter bits in position,
- h) an arbor end having a centered opening for the insertion of an arbor,
- i) an arbor having a threaded end for insertion of the arbor.
- j) a flange on the arbor, the flange having an outer diameter larger than the centered opening to hold the arbor in place when the threaded end of the arbor is screwed into the threaded opening of the conical body,
- k) recesses in the arbor end to receive ends of the cutter bits and maintain the cutter bits in position, and
- l) drilling a hole through the diameter of the cylinder for the insertion of a lever arm.

A reamer for making a straight cylindrical hole comprising:
- a) a body having a uniform diameter along a majority of its longitudinal axis, and a threaded opening along the longitudinal axis,
- b) a plurality of cutter slots spaced from each other about the longitudinal axis,
- c) cutter bits positioned in the cutter slots,
- d) an arbor end having a centered opening for the insertion of an arbor,
- e) an arbor having a threaded end for insertion of the arbor.
- f) a flange on the arbor, the flange having an outer diameter larger than the centered opening to hold the arbor in place when the threaded end of the arbor is screwed into the threaded opening of the conical body,
- g) recesses in the arbor end to receive ends of the cutter bits and maintain the cutter bits in position, and
- h) an end opposed to the arbor end having recesses of receive ends of the cutter bits and maintain the cutter bits in position.
