Abstract
The device includes a base plate, a longitudinally slidable key vise carriage on the base plate, and an overhead support for a manually operable key file. The various components cooperate in such a manner as to permit adjustments in the successive spacing between cuts, angles of the cuts relative to the longitudinal axis of the key as viewed in plan, depth of the cuts and slope of the floor of the cuts, the latter adjustment being effected by securing the key in the key vise in various rotative positions.
Claims5
A manually operable universal key cutting device including, in combination:
- (a) a base plate;
- (b) longitudinally extending means on said base plate;
- (c) a key vise carriage plate mounted on said longitudinally extending means for longitudinal movement along said base plate;
- (d) a supporting means extending upwardly from said base plate;
- and
- (e) a key file guide vertically movable in said supporting means whereby when a file is received in said key file guide and a blank key held in said key vise carriage plate, the spacing of successive cuts on the key blank by said file can be adjusted by adjusting the longitudinal position of the carriage plate on the base plate and the depth of cut can be adjusted by adjusting the vertical position of said file guide in said supporting means.
A manually operable universal key code cutting device, including, in combination:
- (a) a base plate having a central rectilinear longitudinal guide channel and a series of support openings lying on circumferential portions of a circle on diametrically opposite sides of said channel, the center of the circle lying on the longitudinal axis of said channel;
- (b) a key vise carriage longitudinally slidable in said channel;
- (c) a cylindrical key holder for a blank key to be cut rotatably receivable in said key vise carriage;
- (d) an overhead supporting means having legs received in a selected pair of said support openings diametrically opposite to each other;
- and
- (e) a key file guide vertically movable in said supporting means
- whereby when a file is received in said key file guide and a blank key is received in said cylindrical key holder, said file can be manually moved back and forth over the key blank to make a cut, the longitudinal position of the cut being adjusted by sliding said key vise carriage in said base plate, the angle of the cut being adjusted by the selected support openings for said supporting means:
- the depth of said cut being adjusted by the vertical position of said key file guide in said supporting means;
- and the slope of the cut being adjustable by adjusting the rotative position of said cylindrical key holder in said key vise carriage.
