SPECIFICATION forming part of Letters Patent No. 390,515, dated October 2, 1888.
Application filed August 2. H88. Serial No.28l,794. (No model.)
To aZZ whom it may concern.-
Be it known that I, ALVA OWEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have inventedanew and useful Improvement in VVire- Cutting Machines, of which the following is a specification.
My object is to provide a rapidly-operative machine for cutting wire to desired lengths, and which shall be readily adjustable to increase or diminish the lengths of wire to be produced. 1
My invention consists in the general construction of my improved device, and in details ofeonstruction and combinations of parts.
In the drawings, Figure l is a top plan view of my improved machine; Fig. 2, a bottom plan view of the same; and Fig. 3, a section taken on the line 3 3 of Fig. l, viewed in the direction of the arrows, and showinga detail as broken away.
A is a bed-plate provided with a block portion, A, preferably integral therewith on its underside toward one end. Screw-holes t extend through the bed-plate A and block A,to afford means for securing the device upon a support.
On the bed-plate A toward its forward end, or end provided with the block portion, is a guide-plate, 9, provided with a longitudinal groove (indicated by dotted linesin Fig. 1) on its under side. The forward edge of the bedplate and block portion is recessed to receive a metal plate or die, 0, which projects above the surface of the bed-plate A, and is provided toward its upper edge with a perforation, 0, in line with the groove on the under side of the guide-plate g. D is a lever fulcrumed at p (by means of a screw passing through it and the die 0 into the bedplate) and provided with a slot and cuttingedge, 0.
E is an adjustable gage comprising a stop or plate, F, supported vertically on the ends of, preferably, two sliding rods, m m, which pass through close-fitting holes in the block A, and are thus supported near and parallel, with the undersurface of the bed-plate. While one rod m would answer the purpose of two in most respects, I prefer to employ two, as shown, on account of the increased strength and steadiness thereby secured. In either case a sliding frame for the stop is afforded. A cross-head, Z, connects the rods m m at their ends opposite the stop F. G is a bar rigidly attached at one end to the erosshead land supported in a guide, a, secured to the under side of the bed-plate.
The bar G is provided on its under surface with teeth forming a rack, 7t, and on its upper surface with a graduated scale, A pinion, h, on one end ofa shaft, h, supported in bearings h underneath the bed-plate, is in mesh with the rack k, and is rotated to move the latter longitudinally by means of a thumb nut, h, on the opposite end of the shaft h. The bar G is secured in any adjusted position, preferably by means of a cam, g, which may be thrown in or out of contact with. the edge of the bar by turning the handle 9. Any other suitable means for the purpose may be employed. A perforated guide, f, for the wire to be cut, is secured to the projecting end of the bar G, as shown.
The operation is as follows: The gage is adjusted to insure the cutting of the sections of wire to a desired length by turning the th umb nut h, which causes the stop F of the gage E to approach or reeede from the die G,depending upon the direction of turning of the thu mbnut. The graduated scale iserves to indicate as it passes a given point the exact distance between the inner face of the plate F and the die 0. An end of the wire to be cut is then passed through the perforation in the guidef, thence through the groove on the under side of the plate q and through the hole 0 in the die 0 against the plate F, which is the limit of its forward movement. The lever I) is then operated to cause the cutting-edge ate pass the opening 0 and sever the wire. The operation of cutting the wire into sections of the proper length may be repeated by simply advancing the wire until its forward end strikes the plate F, and severing it, as described. The wire as it approaches the plate F is liable to turn from its course and strike the plate at a point away from the direct line. A deviation of this kind, however slight, causes a corre sponding lengthening of the section to be severed, which would destroy the exactness required in the lengths of the sections. To ob viate this, I provide a flaring guide, H, upon the plate F, with its flaring end toward the opening 0 and its converging end surround ing the point upon the plate F nearest the opening 0. The flaring guide H is provided with a longitudinal slot, 6, on its under side. As the wire is pushed forward from the opening 0 toward the plate F, it enters the flaring guide H and is directed to the proper point in line with opening 0 on the plate F. The sections as they are cut drop out of the flaring guide through the slot 6.
What I claim as new, and desire to secure by Letters Patent, is-
l. A wirecutting machine comprising, in combination, a bed-plate, A, a cutter on one end of the bed-plate, and an adjustable gage, E, connected with the bed-plate and comprising a stop, F, supported on a sliding frame, and a bar, G, and means, substantially as described, for securing the gage E in its adjusted position.
2. A wire-cutting machine comprising, in
combination, a bed-plate, A, a cutter on oneend of the bed-plate, and an adjustable gage, E, connected with the bed-plate and comprising a stop, F, supported on one end of a sliding frame, and a bar, G, at the opposite end of the sliding frame provided with agraduated scale, and a rack, is, a shaft, h, carrying a pinion, h, engaging with the rack, and means, substantially as described, for securing the gage E in its adj nsted position.
3. In a Wire-cutting machine, the combina-' tion, with the bed-plate A, a cutter upon the bed-plate, and asliding gage, E, havinga stop, F, of a flaring guide, H, upon the stop F, in the line of the feed of the wire, and provided with a slot, a, substantially as described.
