ABSTRACT:
BACKGROUND OF THE INVENTION 1. FIELD OF THE INVENTION
The present invention relates to a new and improved wood cutting apparatus. More particularly, this invention relates to an apparatus on which relatively thin wafers or strips of wood may be fed in guided manner under a cutting blade and thereby cut in various contoured pieces, which in turn are inlaid together to form various desired patterns in an art known as marquetry. 2. Description of the Prior Art
Heretofore the practioner of marquetry, that is the art of inlaying with wood, has used a fine saw to cut out veneers for inlaying. The saw is mounted in a bow or arched handle, and worked in short quick movements, sometimes to cut three or four veneers simultaneously. Inlaying is practiced sometimes by the use of woods of different colors, grain structure, and the like; sometimes by the use of wood cut to different contours or shapes, but having complementary edges so as to allow for interfitting; and sometimes by the use of woods to both different contours and from woods of contrasting colors and/or grain structure to provide both interesting and attractive products. For example, to obtain a finished product with contrasting colors, a dark wood may be used in combination with a tulip-wood or to obtain a product with contrasting color and grain structure, use of holly and walniat provides an attractive product. Subsequent to conceiving the present invention, applicant caused a prior art search for relevant prior art to be conducted in the United States Patent Office. In the course of the search the patents listed below, which constitute the most relevant art noted, are brought to the attention of the Examiner to be assigned to examine this application:

Considering the art cited above, it is appears that paper cutting type or Guillotine apparatuses, which on first blush, might seem to be suitable for use to achieve the objectives attained by the present invention, include those disclosed in U.S. Pat. Nos. 291,509; 2,889,877; and 5,249,495. To produce the desired contoured pieces on such apparatuses, as disclosed in the cited patents, requires considerable skill, dexterity, attention, and determination on the part of the operator in manipulating, holding, and feeding the wafer or strip of wood to the respective cutting members of the prior art. The apparatuses of the cited patents, while possessing some structural features enabling cutting action, which merely remotely resemble that of the present invention, but owing to deficiencies in their structural details and arrangements, they fall far short of the mark of enabling one to turn out the desired contoured pieces as efficiently and neatly as the present invention does.
The patents listed above, which constitute the most relevant art known by applicant with respect to the disclosed invention, relate to cutting apparatuses having structural details generally similar to several components of the subject matter for which a patent is sought. Such details of the prior art, however, neither anticipate nor render obvious the apparatus disclosed herein.
SUMARY OF THE INVENTION
The present invention provides an apparatus whereby an artisan of average skill and knowledge may, consistent with the intended objectives of the disclosed invention, readily put it to use in cutting relatively thin wafers or strips of wood into various contoured pieces for forming decorative patterns, for example, in an inlaying procedure to provide a decorative work of art. As noted above, in the practice of inlaying with wood, the artisan has, heretofore had to cut the pieces of inlay members by hand with a saw, which needless to say can turn out to be quite tedious. This application relates to a new and improved apparatus for cutting a plurality of contoured pieces of wood for forming an inlay of a desired pattern in a groove of a decorative wooden member from thin strips or wafers of end grain portions of hard wood. While commercially developed versions of such prior art devices are unknown to applicant for whatever reason, whether it be due to inherent deficiencies or other shortcomings thereof, the present invention has been developed to avoid the shortcomings of the prior art devices and meet the longfelt need therefor.
A principal object of the present invention is to provide a new and improved apparatus for cutting contoured pieces of wood for forming an inlay of a desired pattern in a groove of a decorative wooden member from thin strips or wafers of end grain portions of hard wood.
It is another object of the invention to provide a new and improved apparatus for cutting a plurality of contoured pieces of wood for forming an inlay of a desired pattern in a groove of a decorative wooden member from thin strips or wafers of end grain portions of hard wood.
It is also an object of this invention to provide a new and improved apparatus which requires less handling and manipulation of the stock material to be fed to the cutting element to produce contoured pieces of wood for forming an inlay of a desired pattern in a groove of a decorative wooden member from thin strips or wafers.
It is further an object of the present invention to provide an improved apparatus which effects greater operator safety in requiring less handling and manipulation of the stock material to be fed to the cutting element in producing contoured pieces of wood for forming an inlay of a desired pattern in a groove of a decorative wooden member from thin strips or wafers.
Other objects and advantages of the present invention will be readily discernible to the reader upon closer examination of the following description taken in conjunction with the accompanying drawings.
