Patented Dee 27, 1927.



Application led April 24, 1923. Serial No. 634,243.

My invention relates to` improvements in paper clips of the type known generally as Gein clips and it has for its) eneral ob ject to provide a clip in which t e portlons a ci the surfaces which are adapted to con- 'tact with the sheets of paper or other lilre` ilu 'lully appreciated reference may be had to.

the accompanying `drawings in which I have illustrated the invention as embodied in a number of clips.

ln the drawing: Q lfig. 1 is a view in side elevation cfa wire provided with oppositely disposed notches therein which notches extendat right angles across the said wire;'

lllll Fig., 2 is a longitudinal sectional View o` au `the wire taken at right angles to the said notches;y

Fig. 3 is a plan view of a paper clip con structedof alsection of the wire shown in Figs. 1 and 2;

Fig. 4 1s a v1ew in side elevation looking toward the left in Fig. 3;

Fig. 5 is a plan view of a paper clip showing the notches in the wire extending at an acute angle thereto;

Fig. 6 is a view in side elevation of a ortion of the wire of the clip shown in ig. 5; v

Fig. 7 is a view in plan of a portion of wire showing the notches crossing each othia er;-and

Fig. 8 is a view showing a still further modification of the structure in which the' notches upon one side of the wire are extended in one direction while thoseuponI thc au opposite side are extended in crosswiserelation thereto. y

Referring to the drawing: 1 desi ates a wire of indefinite or undetermined en'gth provided with notches 2 arranged at inter- 56 vals thereon. These notches are Vprovided upon opposite sides of the wire in opposed fgsaid clips `to rmly hold a plurality' of -sheets lo 4cated at 13` and 14. The extendedfportion '13 is connected with the portion 1 0 by means relation to each other, as shown. The said notches may be produced in any, suitable manner and by any suitable means but I have found that they may be most economically and elciently produced bypassing the wire between a couple of oppositely disposed and co-acting knul-led rollers. After a wire has been notched eitherv as indicated in Figs. 1 and2`or otherwise it is cut into sections as indicated by the dash and dot lines 3 in Fig. 1 which sections are subsequentlyv bent to form clips ofthe character shown in planin Figs. 3 and 5 ot the drawing.

In the formation of the notches in the wire the metal upon opposite sides of the notch is slightly expanded, as indicated" at 5, so as to form slightly elevatedor projecting portions upon the opposite sides of the notches. The presence of ysuch elevations and notches in the sections of wirel frein1 which the clips are constructed causes the paper or the like upon which the B0 said clips may be placed.

In Figs. 3 and L1 of the drawing I have shown a clip constructed of wir-erin whichV the notches are of the character `illustrated inv Figs. 1 and 2; that is to say,'the notches extendatright angles to the length of' the wire. In the vmanufacture of the clips from wire sich asis shown in Figs. 1 and 2 such wire is cut into short lengths o r sections, as above indicated, which sections are-bent to form a U-shaped portion 9 having parallel legs 10 and 12. The end portions of these legs are bent and extended, as indies of a bend, as indicated at 15while the extended portion '14 is' connected with the part 12 by meansof abend, as indicatedy at 16. The bends 15 and 16 are spaced from lm l each other as indicated and may lbe described as being concentric with respect to each other.- The extended portion 13 is located inside of the portion 12 and in parallel relation thereto. It is situated between -thepor tions 10 and 12. The extended portion 14 is situated outside of ,and in Yparallel relation to the ortion 10. The" portions 13 and 14 are lustrated as being in contact respectvelywith the portions 12nd 10,

but such contact relationship is tial to the invention.

are of such character that they ho U-shaped portions which are connected together by the bend which connects the portions 10 and 12 together. The said U-shaped portions formed in the'opposite end portions of the wire constitute the holding portions of the fastener.

Referring nowto Fi s. 5 and '6 it will be observed that the notc es 18 are arranged at an inclination with respect to the length ofthe wire; that is to say, at acute angles with respect to the said Wire. The clip, as shown in Fig. 5, is provided with the ortions 10, 12, 13, 14, 15 and 16 correspon ing to the parts similarly designated in Fig. 3 of the drawing.

In Fig. 7 I have shown a construction in which the notches 20 and `21are arranged in couplesupon opposite sides of the wire and'in which the notches of each couple cross each other, as indicated. I have shown the vnotches only upon one side of the wire but it will be understood that similar notches construction in which the notches 22 and 23` are arranged at intervals singly upon op- .posite sides of the wire and at angles to each other. In the construction as shown the notches 22 upon the top sides of the wire which are shown in .full lines are arranged at an angle of substantially ninety degrees with respect to the` notches 23 shownl in dotted lines upon the opposite side of the It will be seen from the foregoing that the notches may be arran ed in almost any manner as may be desi or preferred. It will also be seen that byreason of the expansion of the material in the formation of the notches immediatel adjacent the opposite sides ofthe same t e gripping surfaces of the portions of the wire constituting the clip l securely and eiciently the sheets which may be placed between the holding parts of the clips.

It will also be seen that the notches are provided continuousl alo o posite surfaces' of thev wire o whic -t e clips are produced so that in the completed clips the notches are provided upon all portions thereof thereby rendering more efficient the action of the clips in holding a number of sheets upon which the said clips ma be laced.

It will be noted further t at tie notches and slight elevations upon op osite sides of the wire of a clip are arran ed in diametf rically opposed relation to eac other. This arrangement is preferred because it has been found that by arranging the notches and the slight elevations of the metal upon opposite sides thereof in opposed relation to each other they co-operate more directly with each other an therefore are more eicient in their action in holding a number of sheets of paper `which may be laced therein.

Although it is preferred that the notches shall be provided upon opposite sides of the wire of which the clip 1s constructed, as

vshown in the drawing, yet if desired the clips may be made of wire having notches only on one side thereof.

Having thus described my invention, what I claim and desire to secure by Ifetters Patent is: y

1. A paper clip comprising a section of wire, the opposite ends of which terminate in U-shaped portions the intermediate portion of the said wire hein bent to U-shape so as to locate the said -shaped o'rtions in nested and operative relation with respect to each other, and the wire of the said clip being provided with notches upon its op posite sides which notches extend at an inclination with respect to the length of the said wire.

2. A paper clip comprisin a'section of wire, the o posite ends of w ich terminate in U-sha e portions, the intermediate portion of t e said wire being bent to U-shape so as to locate the said U-sha d portions in nested and operative relation with respect to each other, and the wire of the said c ip being provided with groups of notches arranged at intervals on opposite sides thereof, the notches of each group extending at angles with respect to each other. l

In testimony that I claim the foregoing as my invention I have hereunto signed my name this 18 day1 of April, A. D., 1923.
