T0 ALL WHoM IT MAY CONCERN:
Be it known that I', EDWARD J. ARENS; of Boston, in the county of Suffolk, and State of Massachusetts, have invented anew and useful Improvement in Monlding-Cutters; and llido hereby declare the following to be a full, clear, and exact description of the nature thereof, sufficient to enable others skilled in the art towhich it appert'ains to fully understand and use the same, reference being had to the accompanying drawings, making part of this specification, in which` Figure 1 is a perspective view ofthe cutters illustrating my invention as applied to a moulding-cutter head.
Figure 2 is a front view of the cutting edge. l
Figure Slis a view of' the back of the cutter.
Figure 4 is a view of the' face of the cutter.
Figure 5 is a View of the back end thereof.
Similar letters of reference indicate corresponding parts in the several figures.
This invention of' a cutter intended for forming mouldings consists in so constructing its face that it will cut equally well across and against the grain as with the grain, and produce a smooth `cut in each case. The form or pattern of the cutter isrst made in the stock. The face side is'then planed or taken out so as to leave certain angles or ridges relatively to said pattern that when the back side is sharpened the cutting portionfor each member will consistct` two diagonal faces meeting at the ridges, and whose lower ends unite with those of their adjacent cutting portions and form the parts which cut the grooves or channels between the beads or 1nembers. The knives or cutters will be mounted ona revolving arbor and will always cut downward and upward, and the vcutting will first commence at the lower' part of the diagonal faces and end at the meeting point, thereby the cutting will bevdiagonally from these lower parts to the meeting point. There will be no tearing or ripping of the wood, whetherthe member be large or of the most minute pattern, regardless of the grain of the wood, whether across, against, or with it.
In the drawings, A represents the cutter, consisting of a stock, whose face is represented at B and back at C. D represents the cutting edge and E thel back end of the cutter. A suitable pattern is made on the stock, and the face is then cut out or planerl longitudinally, so as to leave certain longitudinal ridges or angles relatively to thel'pattern. The back is now properly ground to an edge, and it will be perceived that the cutting portion for each member will consist of two diagonal faces a b, which meet at a certain point, c, of' the angle on the face of the cutter. 1When the cutter is applied to an ordinary cutter-head, and suitable power applied thereto, the cutter will make a striking diagonal or slanting eut, and consequently the member wili he cut smooth easier and with less power than ordinary. The wood to be employed for moulding can be selected with outI regard to its grain, for `the cutter will perform its work equally well,lwhether across, against, or with the grain. y
-Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
`Amoulding-cutter whose cutting edges for each vmembei.- consist of diagonal faces meeting at the angle or ridge on the face of the cutter relatively to the form or contour of the moulding, substantiallyas described.
