INVENTOR MM E LM H Mu PM 6 E GY B ATTORNEY Patented Nov. 1, 1938 UNITED. STATES PACKAGIN'G DEVICE George M. Ehlcrs, Milwaukee, Wis, assignor to Globe-Union Inc., Milwaukce,.Wis., a corporation of Delaware Application March 19,
compactly mounting and packaging resistors of this type with the resistors releasably though securely held in position in such a way that their end leads are adequately protected and main tained in straight extended position parallel to each other. The resistors are neatly arranged and attractively displayed and this, in such manner that they may be inspected without removal. Moreover the device facilitates and simplifies the counting of the resistors. mounted on each device and counted as a unit. And the device lends itself to automatic loading of resistors.
Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawing, forming a part of this specification, and in which:
Figure 1 is a perspective view of a device embodying the present invention as it appears before being loaded with resistors;
Figure 2 is a similar view of the device loaded with resistors;
Figure 3 is a perspective view of the underside of the device; V
Figure 4 is a fragmentary view in top plan and on an enlarged scale showing how portions of the sheet or blank are cut and folded to engage and Referring to the drawing the numeral l designates a rectangular sheet of light material pose sessed of suitable resiliency to enable it to be Heavy paper or light weight cardboard of appropriate quality may be advantageously employed.
At spaced points along the center of the sheet.
50 it is stamped or cut out to provide rectangular slots 2. The material of the sheet along each side edge of each slot is also formed with a row of V-shaped notches 3. At the inner edge of each,
notch 3, a slit 4 is formed and at the inner end Any number may be stamped and formed up in the manner shown.
of each slit the material is perforated or formed 1937, Serial No, 131,842
with a small circular hole 5. The notches, slits and holes at one side of each slot are transversely alined with those at the other side thereof. All the notches, slits and holes are of substantially the same dimensions. A short distance outwardly of each row of holes 5, the material ofthe sheet is indented or creased or otherwise provided with a line of fold 6 so that the strip-like portion between each line of fold 6 and the adjacent edge of the slot 2 may be bent up to form a" vertical flange I along each side edgerof each slot. The material of the sheet'is sufliciently stifi to insure the flanges I remaining vertical after they are once bent up to such position.
With a device constructed in this manner it may be loaded with resistor R by presenting the portions of the lead wires L adjacent the resistor ends to transversely alined notches 3 and pressing or pushing such portions down through the slits 4 and into the holes 5. It will be seen that while the notches and holes are not essential to the support of the resistors they are of substantial advantage in that they respectively facilitate the assembly and allow the material of the supporting flanges I to frictionally grip the lead wires without excessive distortion of the paper.
When assembled with the holder the resistors are arranged in groups, groups of ten in the structure illustrated, and the resistors of each group are disposed parallel and closely adjacent, with the lead wires in straight extended position and close to the imperforate portions of the sheet to be protected thereby. The holders may be piled or stacked one on top of the other and when so stacked maybe compactly packaged. Since the surface of each sheet, the top edges of the flanges I of one sheet are partially interfitted in the slot 2 of the next overlying sheet when the holders are stacked.
While I have shown and described my invention as capable of advantageous use in packaging fixed resistors it-is obvious that it may be used with equal advantage for the packaging of end lead condensers or'other electrical devices of similar structure. 1
While Ihave shown and described one construction in which the invention may be advantageously embodied, it" is to be understood that the constructions shown have been selected merely for the purpose of illustration or example and that various changes in'the size, shape and arrangement of the parts may be made without departing from. the spirit of the invention or the scope of the subjoined claims.
resistors are supported slightly above the top The invention claimed is:
1. A holder for fixed resistors having end leads and comprising a flat sheet of material provided with longitudinally spaced slots and having ver tical flanges along each longitudinal side edge of each slot, said flanges having transversely alined slits adapted to receive and frictionally grip portions of the end leads and retain the end leads in straight extended position closely adjacent a surface of the sheet to be protected thereby.
2. A holder for fixed resistors having end leads
