" JOHN FRITZ, or NEW EEDFonn, MASSACHUSETTS.

PAPER-CLIP.

Specification of Letters Patent.

Patented Aug. 6, 1918.

Application led Decembero, 1916. Serial No. 137,992.

To all whom 'it may concern:

Be it known that I, J oHN FRITZ, a citizen of the United States, and a resident of New Bedford, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Paper-Clips, of which the vfollowing is a specification.

`My invention relates to paper clips of unit form, one of the main objects thereof being to provide a relatively large and strong prong which, after being forced through the paper to be bound together, is deected and permanently seated in a pocket, and .another object is to provide relatively small supplemental prongs adapted, after having passed through the paper,

to be seated in indentations to prevent lateral movement of the plate members of the clip with respect to the paper and to each other.

My invention is fully described in the following specification, of which the accom- Vpanying drawingsform a part, in which like characters refer toy like parts in each of the views, and in which Figure 1 is a view ofone side of my clip applied to one or more sheets of paper;

Fig. 2 is a similar view of the opposite side thereof; I

Fig. 3 is an enlarged central longitudinal section taken through my clip and through a sheet of paper, previous to clamping the clip in locking position;

Fig. 4 is a similar section, with the clip clamped in locking position Fig. 5 is an enlarged section taken on the line 5-5 of Fig. .2; I

Fig. 6 is a view of the clip, as marketed, viewed toward its open end, with a sheet of paper in position; and

Fig. 7 is a section taken on the line 7 of Fig. 6.

Referrin to the drawings, 8 represents Y a punctura le sheet, or sheets, to which it is desired to secure my clip, the latter being formed of a strip 9 of thin sheet metal bent centrally 0n a transverse line to form two

plate members

10 and 11, the former of which has a relatively large prong 12 and two relatively small prongs -13 Stamped therefrom and bent toward the plate memi 14 stamped therein with an inclined bottom i adapted to bend the point of the prong 12 and thus the prong itself to rest within said l pocket, lsaid plate member also having a tongue 15 stamped therefrom and bent to partially cover said pocket and thus prevent the escape of the bent prong 12 from the pocket when the clip is clamped in place, Fig. 4, the end of said tongue being bent downwardly into said pocket to prevent its interference with any sheets of paper introduced between the two

plate members

10 and 11.

The plate member 11 is also provided with two slight depressions 16 adapted to receive the small prongs 13, Fig. 5, when the clip 'is clamped into locking position to prevent lateral movement between the plate members and, thus between the clip and the sheets bound thereby, the prongs 13 being slightly'upset at their points when the clip is clamped, Fig, 5 showing only a partially clamped position. l

Because of the large prong 12 kmy clip is locked in place in a positive manner ren- 'Itl dering the separation of the plate members The clip is very slmple in. constructlon and in use, as well as very inexpensive, and, while I have shown a preferred embodiment I reserve the right to make such changes as come iwithin the scope of the appended claim. v f

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

As a new article of manufacture, a paper clip formed of a strip of sheet metal bentupon itself to form two members, ore member being provided with a long and two short prongs struck up therefrom, the long prong being at the center and the short prongs adjacent the sides of the member,

the other member, opposite the long prong, downwardly and extending partially over being bent downwardly to form a recess the recess and forming therewith a pocket having an inclined bottom, and provided to receive the said long prong.

with side openings to receive the short JOHN FRITZ prongs and with a tongue struck up there- Witnesses: from between the recess and the junction of JOSEPH T. KENNEY the two members, the said tongue being bent ALICE M. HIBBARD.
