LA GEE TABER, OF MERIDEN, CONNECTICUT.
BURNISHING KNIFE-BLADES.
SPECIFICATION forming part of Letters Patent No. 241,750, dated May 17, 1881.
Application filed March 14, 1881. (No model.)
. To all whom it may concern:
Be it known that I, LA GEE TABER, of Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in Burnishing Knife-Blades; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-
Figure 1, a top or plan view; Fig. 2, a frontproved itself capable of burnishing the blades in the most perfect manner, consists in the construction as hereinafter described, and particularly recited in the claims.
A represents a cross-head with a shank, B, arranged to set into a reciprocating spindle or slide, C, of a burnishing-machiue, or may be attached to any device which will impart to it a reciprocating movement. At each side of the center of the cross-head arms I) and Dare hinged, as at a. The outer end of these arms are fitted with a burnishing-roll, d, such as commonly used, and made from hard finelypolished steel or from other suitable material, and should be in the shape of wheels hung upon an axis substantially parallel with the path of movement of the burnisher-arms, and as shown the two burnishers are in the same transverse line-that is, in the same plane. The blade E of the knife is placed between the burnishers and substantially parallel with their path of movement, the handle F firmly secured in a holder, Gr, and so that one burnisher will lie upon one side of the blade and the other upon the opposite side, as shown, and so that as the burnishers are moved along the sides of the blade from bolster to point they burnish the surface over which they pass, and as they pass back and forth from bolster to point either the blade is moved slowly up or down or the' burnishers are so movedthat is to say, so that, beginning at the back of the blade, the burnishers will gradually work toward the edge until they pass from it, leaving the blade completely and periectlyburnished.
As here represented, the holder for the knife is arranged to move up and down by means of a hand-screw, L, in connection with the holder .G, the said holder being arranged between guides H H, as shown.
Any convenient device may be arranged for clamping the handle in the holder, as by a setscrew, e, or otherwise, arranged, however, with some protection between it and the handle to prevent the clampingfrom injuring the handle.
It will be understood that other means may be employed to cause the burnishers, during their reciprocation on the opposite sides of the blade, to gradually work from one edge of the blade to the other.
To make an elastic pressure of the burnishers upon the blade and equal upon both sides, I hang an arm, P, at each side, as upon a pivot, f, the outer end of the said arms bearing against a cheek-piece, It, and preferably with an interposed anti-friction roll, I, as shown; then, between the burnisher-arms and the arms P, I introduce a spring-pressure, here represented as by a spiral spring, 8.
The cheek-pieces B may be adjustable, so as to correspond to the taper of the blade or to make a greater or less pressure.
Instead of applying the spring pressure through the arms P, pressure may be applied by, say a flat spring extending from the crosshead, as indicated in broken lines on the righthand side, it only being essential that there shall be a corresponding or substantially equal pressure upon both the burnisher-arms.
To prevent the two burnishers from coming into actual contact, a stop, h, is arranged on the cross-head, near the pivot, and a shoulder, 11, on each of the hubs of the levers, which will strike their respective stops and prevent their comin g in contact. These stops are best made in the form of screws, as shown, so as to be adjustable, because in changing the burnish= ers different diameters maybe em ployed. Then such adjustment would be essential, as the burnishers must come so near together that they will burnish the blades down to the sharp edge, and yet should not be so as to come into actual forced contact I claim- .1. The combination oftwo hinged burnisherarms, each provided with its burnisher, means, substantially such as described, to impart a reciprocating movement thereto, with a holder constructed to hold the blade between said burnishers and in the line of movement of said burnishers, mechanism, substantially such as described, to impart to the holder a movement, substantially as described, in relation to the reciprocating burnishers, so that during the reciprocating movement of the burnishers the knife-blade is gradually burnished from one edge to the other, substantially as described.
2. The combination of two hinged burnisherarms, each provided with its burnisher, mechanism, substantially such as described, to impart a reciprocating movement thereto, with a holder constructed to hold the blade between said burnishers and in the line of movement the reciprocating movement of the burnishers the knife-blade is gradually burnished from one edge to the other, and adjustable stops to prevent contact of the burnishers, substantially as described.
3. The combination of two hinged burnisherarms, each provided with its burnisher, mechanism, substantially such as described, to impart a reciprocating movement thereto, with a holder constructed to hold the blade between said burnishers and in the line of movement of said burnishers, and mechanism, substantially such as described, to impart to the holder a movement substantially as described in relation to the reciprocatingburnishers, so that during the reciprocating movement of the burnishers the knife-blade is gradually burnished from one edge to the other, with mechanism, substantially such as described, to impart a forced yielding pressure to the burnishers, substantially as described.
