PROCESS FOR MANUFACTURING METAL CLIPS Filed Jan. 7, 1931 INVENTOR ATTORN 7 Patented Jan. 2, 1934 UNITED STATES 'ATEN'E' FFICE PROCESS FOR MANUFACTURING METAL CLIPS Application January 7,
2 Claims.
My invention relates to the process of making metal clips for use with cardboard boxes etc.
The object of my invention is to provide a process for making metal clips by stamping the same from a strip of metal equal to or slightly greater than the length of the clip, and forming rong fastening means integral with each clip, by means of which the clip may be secured to a cardboard box.
A further object of my invention is to simultaneously score the clip along the lines where the same is to be bent to insure the clip bending easily on said lines.
A further object is to weaken the clip along the middle or median line to insure the clip being bent at this point.
Referring to the drawing which forms a part of this specification:
Figure 1 is a plan view of a portion of the strip 20 of metal showing the form of the clip to be stamped therefrom.
Figure 2 shows a longitudinal sectional View of the clip bent at right angles on the median line and adapted to fit over the corner of a cardboard box.
Figure 3 is a top edge view of the clip after it has been bent to a right angle.
Figure 4 shows a portion of the strip of metal with a clip of modified form relative to that shown in Figure 1.
Figure 5 shows a further change in form of a clip to be stamped from the strip.
indicates a strip of thin sheet metal which may be iron or brass or other suitable metal for the purpose stated.
11 indicates the respective clips stamped from the sheet 10.
The clips are formed by the use of suitable dies comprising male and female portions, between which the sheet is fed, and from which the clips 11 may be consecutively stamped.
The dies are made to provide a score on the dotted lines 12.
V shaped prongs 13 are formed integral with the body portion 11 and are bent inward as illustrated in Figures 2 and 3, the bend taking place on the dotted lines 14.
The prongs 13 are pressed through the cardboard at each side of the corner of the box and clamped on the inner side thereof to hold the body portion 15 of the clip to the box and braces and strengthens the corners thereof as may be readily understood.
The end portions 16 are passed through holes in the cover of the box and bent over to secure 1931. Serial No. 507,109
the cover in position as shown in my application for Metal clips, Serial No. 508,648 filed January 14, 1931, Patent No. 1,908,667, dated May 9, 1933, in which application the use of the clip is clearly set forth. See also my application Ser. No. 507,108 filed January 7, 1931, Patent No. 1,872,734, dated August 23, 1932.
To permit the clip to be easily bent at the middle portion of the body on line 12, the clips are notched on each side as shown at 17. These notches may be of any desired depth to accomplish the function stated.
The dies may be made to bend the clip on line 12 slightly in opposite directions, as shown in dotted lines in Figure 2, so that as the clip leaves the dies the prongs are bent and formed as shown in Figures 2 and 3, and the body portion offset on the lines 12 to facilitate the application of the blank to the box corners, as will be readily understood.
Having thus described my invention I claim as new:
1. The process of making a metal clip consisting in stamping the clip from a strip of metal, simultaneously imparting three transverse and parallel initial bends to the clip to divide it into four sections, the intermediate initial bend being in a reverse direction to said other initial bends, and simultaneously forming and bending fastening prongs from the body of the clip at each of the inner sections thereof intermediate the width of the clip.
2. The process of making a metal clip consist ing in stamping the clip from a strip of metal, simultaneously imparting transverse and parallel initial bends to the clip in opposite directions, and simultaneously forming and bending fastening prongs from the body of the clip at each side of one of said initial bends intermediate the width of the clip.
