SPECIFICATION forming part of Letters Patent No. 352,056, dated November 2, 1886.
To all whom,v it may concern.
Be it known that I, OsCAR. E. HILDEBRAND, a citizen of the United States. residing at N orwich, in the county of New London and State of Connecticut, have invented certain new and useful Improvementsin Beading-Tools. which improvements are full y set forth and described in the following specification, reference being had to the accompanying drawings, in Which- Figure 1 is a side view ofsaid improved tool, and Fig. 2 a top view of the same. In Fig. 3 I have shown a transverse sectional view on. line a; a: of Fig. 2.
My improvements are in that class of tools used commonly by Cabinetmakers and other wood -workers for grooving, channeling, or beading work, which cannot easily be done by machinery; and my object is to provide a practical tool, which shall be serviceable and strong, yet cheap.
My device is preferably constructed entirely of metal, the seve. al pieces being of such shape that they may be assembled with but little fittin l eferring to the drawings, the letters a a represent rods, which are semicircnlarin crosssection and of sufficient length to receive at each end a handle, b, which handle I prefer to make of cast-iron. These handles are cored centrally throughout their length to'slip over the two rods c a, as will be understood by referring to Fig. 3, and are shaped at their inner ends with flanges c c, which form gages to guide and control the movement of the knife when in use.
My cutting-tool proper is punched or otherwise formed from steel, and asingle blank may have, if desired, several cutters of different designs .on its opposite edges, as shown at d in Fig. 1. The cutter thus formed is entered between the flat sides of rods a a. and'the handles b are then adjusted to form the bead at the desired distance from the edge of the board, the depth of the out being determined by the Application filed July 15, 1856. Serial No. 208,051. (No model.)
distance which the cutter projects below the rods. In order to clainp the parts thus adjusted firmly together, I have drilled and tapped the handles to receive clamping-screws e e, which, when screwed home, clamp the parts as rigidly as if they were integral with each other.
By forming my entire fool of metal, I find that the weight thus gained gives an impetus to the tool, which is desirable rather than objectlonable, inasmuch as it requires less effort on the part'of the operator. In many cases the thumb-screws e 0 may be dispensed with, the handles being forced onto rods aa, which action squeezes the rods together sufficiently to hold the cutter; but as a rule I prefer to use clamping-screws, as shown.
Having described my invention, I claim- 1.; In a beading-tool, in combination with two companion rods, a' cutter adapted to be clampedbetween said rods, as described, and
handles cored to slip over said rods to clamp the said cutters, all being substantially as herein specified I 2. In combination with two semicircular rods, a cutter adapted to be clamped between said rods, and handles cored to slip over said rods, as described, said handles being provided with clamping-screws, by which the several elements may be clampedtogether, for the purpose specified.
8. In combination with two companion rods, a cutter adapted to be clamped between said rods, as described, handles cored to slip over the ends of said rods and formed with gageflanges at their inner ends, and thumbscrews or similar means f0 rtcla m pi n g the several parts 7 together, substantially asherein set forth, and for the purpose specified.
