OLOVIS PIEROTIN BLAVIER, OF PARIS, FRANCE.
lM PROVEM ENT IN RATTAN-CUTTERS.
Specification forming part of Letters Patent No. 217,855, dated July 29, 1879 application filed I March 31, 1879.
To all whom it may concern:
Be it known that I, OLovIs PIERoTIN BLA- V'IER, of Paris, in the Republic of France, have invented a new and useful Improvement in Rattan-Gutters, of which the following is a specification.
The invention consists in an improvement in tubular knives used in clusters for cutting a or trimming rattan.
Hitherto, in making a cluster of tubular knives from or in a single block or bar of steel, the holes have been bored through the block or bar as near to each other as was practicable, with their axes in parallel lines, and at the end of the block designed for the cutting end the steel left between the holes, as well as the steel around the cluster, has been filed to a cutting-edge. The difficulty with this construction has been that where the holes were far enough apart to leave sufficient strength in the block or bar their diameters have been larger at the cutting ends than throughout the remainder of the tubes, making it necessary to pull each divided strand through a hole having a diameter smaller than its own. I have remedied this difficulty by boring the holes in the block or bar of steel so that their axes diverge, substantially as shown in the accompanyin g drawings,whereby I am enabled to give to the hole a diameter constantly increasin g1 from the cutting end to the rear end of the too In the drawings, Figure 1 is a front view of a cutter embodying my invention. Fig. 2 is a side elevation. Fig. 3 is a front elevation upon an enlarged scale; and Fig. 4is a sectional elevation upon an enlarged scale, showing the divergence of the axes and the increase in the diameter of the tubes.
In making my cutter, the holes are bored from the rear end of the block of steel to the end which is to become the cutting end, and are then tapered, as shown. If the holes do not run into each other so as to give the required cutting-edges to the steel between them,
They serve also to strengthen the tool 5 but they form no part of my invention, except when used with a cluster of cutters having the characteristics hereinbefore described.
I claim- A cluster of tubular tapering cutters with diverging axes, and whose adjacent sides intersect so as to form common cutting-edges, substantially as described, for the purpose specified.
