Application filed March 18, 1885. Serial No. 159,368.
To 60 whom it may concern:
Be it known that I, Joan E. CUMMINGS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Clamping-Tools; and I do hereby declare the following to be a full, clear. and exact description of the invention, such as will enable others skilled in the art to IC which it appertains to make and use the same.
My invention relates to an edging and clampingtool; anditconsists of atool for bending the edges of a thin sheet of metal over a suitable base or block, and at the same time turning and clamping the edges of the metal so bent into suitable grooves or recesses formed in the base or block. It is especially designed for fastening an clectro-shell plate upon a base grooved or slotted to receive the edges of such a plate, and in this connection the invention will be described and illustrated.
1n the accompanying drawings, Figure l is a front perspective view of my invention; Fig. 2, a side view in elevation; Fig. 3, a central vertical section on line at ot Fig. and Fig. 4,an end View of a base and shell, showing the manner in which the edges of the shell are bent and forced into the grooves of a base or block. Fig. 5 is a view of an electrotype o shell having flanges, to the bending and clamping of which my improvement is particularly adapted, Fig. 6 is a sectional detail view of a portion of the tool, and Fig. 7 a detail.
In the drawings, A is the base of the tool;
5 B, an upright central post; 0, a telescopic handle and plunger sliding on said post, and D a coiled spring placed within the handle O, resting upon the post B, and confined in place by the top 0 of handle 0. Hinged to the han- 40 dle on its opposite sides are arms d d, which carry the bending and clamping plates E E. Connected to these arms by a knee or other joint, f, are plates 9.
E E are the bending or clamping plates, riv- 5 eted to the plates 9.. The base A has a smooth under face, and on its sides is provided with flanges G, slotted to receive the bending-plates E, the flanges having their outer corners and surfacesroundedandinner faceinclinedtoward 5c the base. Each slot is divided by a partition,
(ModeL) h, rounded to correspond to the rounded corners of flanges G,as shown. Through these slots pass the bending-plates E, each plate being provided with a central slot, i, to inclose the partitions 71. The rounded uppersuri'aces of partitions hand of the corners of the flanges Gi'orin bearings upon which the central portion, 9, and the shoulders g of the plates 9 ride when the clamping-plates are pressed down, as hereinafter described. The bending- 6 plates extend below the base, and are provided with bevelled edges Z.
In applying this tool to'an electrotype-shell provided with plain flanges, as shown in Fig. 5, the shell is placed upon a block having 6 grooves in running adjacent to and running parallel with the upper lace ot' the block. The plain even face of base A is placed over the lettered part of the shell, and when force is applied to the plungerO the base is pressed upon the lettered face of the shell, leveling the under surface of the shell with the base-block, and at the same time the lower edges. Z, of the bending-plates E are forced toward the block and into its respective grooves, drawing the flanges ot' the shell tightly against the beads of the block, setting its flanges into the grooves against the lower sides of the beads, and fastening the shell securely thereto. The flanges are thus not only turned smoothly and 8:) securely within the grooves, but the shell is stretched tightly across the base-block, and any buckling or bowing-up ot' the shell is prevented, aud all irregularities of the shell smoothed out. The pressure upon the plunger O being relieved the force of the spring automatically lifts the bending-plates, the tool is moved along the block without lifting it off, and the operation of bending repeated. Thus by a rapid succession of strokes upon the 0 plunger by the hand as the tool is moved along a column of any length of shell is securely clamped upon the base in a few seconds.
\Vhen the matter electrotyped on the shell is in the form for printing arranged in 001- 5 umns, the tool can be placed over the column for clamping on the shell with only a slight separation of the columns of the form, thus obviating the annoyance of taking the furniture out of the form and spreading the columns apart, or of taking the base-block from the form, as would be required were the bending of the flanges done from the side.
This tool will be found useful in connection with a grooved base whenever it is desired for any purpose to turn the edges of a sheet of metal inwardly.
Having thus described my invention, what I claim isv 1. A tool for bending the edges. of a metal plate, consisting in the combination, with the slotted base-plate and central post, of the handle or plunger sliding on said post, a
spring, and the bending-plates and connectingarms hinged to the plunger, substantially as and for the purpose described. I
