Abstract
A bottle cutter has a body having two generally arcuate components connected to each other by straight parallel members permitting one component to slide relative to the other component between an open, non-cutting position and a closed, cutting position. Each arcuate component includes a plurality of an inwardly facing rollers that facilitate rotation of a bottle held by the bottle cutter in the closed, cutting position. A cutting wheel disposed on one of the two components cuts, or at least scores, the bottle as the bottle is rotated. If the bottle is only scored, separation of the top and bottom portions of the bottle may be effected using hot and cold water to induce differential thermal stresses in the glass. The edge may be finished or polished using sandpaper or any other suitable abrasive material.
Claims18
A bottle cutter comprising:
- a first arcuate component;
- a first straight parallel member slidably engaged with the first arcuate component;
- a second straight parallel member slidably engaged with the first arcuate component;
- a second arcuate component slidably engaged with the first straight parallel member and with the second straight parallel member, the first arcuate component and the second arcuate component to slide along the first straight parallel member and the second straight parallel member relative to one another between an open non-cutting position and a closed cutting position;
- a first roller rotatably engaged with the first arcuate component to engage with and facilitate rotation of a bottle held by the bottle cutter in the closed cutting position, wherein the first roller is to engage the bottle substantially continuously when the bottle cutter is in the closed cutting position;
- a second roller rotatably engaged with the second arcuate component to engage with and facilitate rotation of the bottle held by the bottle cutter in the closed cutting position;
- a cutting wheel disposed on the first arcuate component for cutting the bottle as the bottle is rotated, wherein the cutting wheel is translatably repositionable relative to the first arcuate component;
- a spring connected to the cutting wheel to urge the cutting wheel toward the bottle to ensure continuous and uninterrupted cutting contact between the cutting wheel and the bottle;
- a first lever pivotably engaged with the first straight parallel member to approach the first arcuate component toward the second arcuate component to tightly secure the bottle between the first arcuate component and the second arcuate component;
- a second lever pivotably engaged with the second straight parallel member to approach the first arcuate component toward the second arcuate component to tightly secure the bottle between the first arcuate component and the second arcuate component;
- and
- a third lever pivotable with respect to the bottle, the third lever to push the cutting wheel against the bottle.

A method of cutting a bottle, the method comprising:
- providing a bottle cutter having parallel members that define spaced-apart slide rails and first and second arcuate components that slide over the slide rails, wherein the first arcuate component comprises a first roller and wherein the second arcuate component comprises a second roller;
- opening the bottle cutter by spreading the first and second arcuate components into an open non-cutting position by sliding the first arcuate component relative to the second arcuate component over the slide rails;
- inserting the bottle between the first arcuate component and the second arcuate component;
- closing the bottle cutter by sliding the first arcuate component relative to the second arcuate component along the slide rails to engage the first roller and the second roller with the bottle to constrain the bottle in a closed cutting position, wherein closing causes a spring connected to a cutting wheel disposed on and translatably repositionable relative to the first arcuate component to urge the cutting wheel against the bottle to ensure continuous and uninterrupted cutting contact between the cutting wheel and the bottle and the first roller is to engage the bottle substantially continuously when the bottle cutter is in the closed cutting position;
- tightening the first and second arcuate components toward one another around the bottle via first and second levers pivotably engaged with the slide rails;
- tightening the cutting wheel against the bottle via a third lever pivotable with respect to the bottle;
- scoring the bottle using the cutting wheel disposed on the first arcuate component by rotating the bottle with the bottle cutter in the closed cutting position;
- separating a top portion of the bottle from a bottom portion of the bottle;
- and
- finishing a cut edge of the bottom portion of the bottle.
