ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to craftsman's turntables. More specifically, the invention is a turntable for cutting designs out of paper with a metal template. The turntable allows for rotation of the paper while cutting. The provision of an armrest makes it unnecessary for the craftsman to have to hover his or her arm over the art work.
2. Description of Related Art
The related art of interest describes various rotatable tables with or without magnetic holding elements. The art of interest will be described in the order of perceived relevance to the present invention.
U.S. Pat. No. 4,861,364 issued on Aug. 29, 1989, to Ted A. Trujillo et al. describes a method for assembling and soldering pieces of stained glass by placing a template to outline a mosaic fit of glass pieces on a workboard by nailing flat sided nails to the outer perimeter on a rectangular workboard attached to a square support plate by hook and latch material strips. The support plate is rotated on a thrust bearing in a base. The apparatus is distinguishable for the omission of a magnetic means and an armrest.
U.S. Pat. No. 4,476,762 issued on Oct. 16, 1984, to Frank T. Anderson, III et al. describes a hydraulically operated cutting die supporting plate apparatus (for cutting envelopes) which contains recessed pairs of bar magnets arranged in a circle to hold the cutting die. The apparatus is distinguishable for lacking an armrest and a hydraulically operated cutting platform configured as in the present invention.
U.S. Pat. No. 4,739,683 issued on Apr. 26, 1988, to Hiromi Ogawa describes an apparatus for cutting a continuously fed material sheet into trapezoidal pieces on a turning table with movable upper and lower cutters. The machine is distinguishable for its automatic operation.
U.S. Pat. No. 5,495,671 issued on Mar. 5, 1996, to Wang Shun-Yi describes a hand operated apparatus for multi-shape cutting of colored paper to form animal cutouts. A circular cutting table assembly with six design cutting means is held within a U-shaped base member with a punching means on one end and the other end functioning as a handle. The device is distinguishable for its lack of an armrest and magnetic holding means.
U.S. Pat. No. 3,949,629 issued on Apr. 13, 1976, to Betty Johnson describes a method of cutting and storing garment-pattern shaped pieces of textile material, wherein magnets and oval metal plates are used to position and clamp the thin paper sheet pattern pieces to the textile cloth. The device utilized is distinguishable for its lack of a turntable and armrest.
U.S. Pat. No. 2,177,905 issued on Oct. 31, 1939, to Louis W. McKeehan describes a holder for drawing paper on a drawing board with a metal plate facing by thick circular magnets in each corner. This holder device is distinguishable for its omission of a separate armrest and a turntable.
U.S. Pat. No. 4,779,543 issued on Oct. 25, 1988, to Daniel Kelley describes a rotatable drafting table having a rectangular configured drafting surface. The rotatable drafting table is distinguishable for the lack of magnets and a separate armrest.
U.S. Pat. No. 4,892,295 issued on Jan. 9, 1990, to Jeanne N. Keller describes a paper sheet holding device for cutting with a pair of scissors along one edge of the device. The device has two square flat blocks hinged at its rear for inserting a paper sheet between the lid and base blocks which have embedded round magnetic disks in each corner. The device is distinguishable for the omission of an armrest and a turntable.
U.S. Pat. No. 5,102,288 issued on Apr. 7, 1992, to Shozo Kawasaka describes a work table for pattern matching of cloth sheets by utilizing an electromagnetizable surface for maintaining metal pins with seats in position. The work table is distinguishable for the lack of a separate armrest and a turntable.
None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed.
SUMMARY OF THE INVENTION
Accordingly, it is a principal object of the invention to provide a craftsman's turntable.
It is another object of the invention to provide a craftsman's turntable with an armrest.
It is a further object of the invention to provide a craftsman's turntable with an armrest for cutting stencils or designs in paper.
Still another object of the invention is Lo provide a craftsman's turntable with an armrest for cutting stencils or designs in paper under a metal pattern or templet held down by a recessed magnet in the turntable.
It is an object of the invention to provide improved elements and arrangements thereof in an apparatus for the purposes described which is inexpensive, dependable and fully effective in accomplishing its intended purposes.
These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings.
