PAIPER-CLIP.

Specification of Letters Patent.

Patented Sept. 6, 1910.

Application filed April 20, 1909. Serial No. 490,991.

To all whom 'it may concern:

Be it known that I, GEORGE HYLKEMA, citizen of the United States, residing at Volga, in the county of Brookings and State of South Dakota, have invented certain new and useful Improvements in Paper-Clips,

of which the following-is a specification.

This invention relates to paper clips and has forits object to provide a comparatively simple and inexpensivedevice ofthis character for, holding two or more detached sheets of pa er together, and. which may also be used or clamping newspapers, magazines and the like and suspending the same from a nail, hook or other suitable support.

A- further object ofthe invention is to provide a paper clip including co-acting spring pressed clamping jaws one of which is provided. with a hump or projection adaptedto ip the paper and thus assist in holding fife several sheets in. amembled position, said jaws being provided with terminal finger p eces by means of which the tion, reference is to be had to the following,

same may be moved to open position thereby to release the paper.-

A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability,

and efliciency, aswell as to reduce the cost of manufacture.

Furtherobjects and advantages will ap-- pear in the following description, it being understood that various changes in form,

the appended claims. V For a flill understanding of the invendescription and accompanying drawings, in which: I

Figure 1 is a perspective view of. apaper clip constructed in accordance with my invention. Fig. 2lis a front elevation of the same. Fig. 3 is a rear elevation. Fig. 4 is a side view showing. the jaws in closed position. Fig. 5 is a similar-view looking at the opposite side of the cli i and showing the jaws in open position. ig. 6 is atop plan view thereof.

Corresponding and like parts are referred to in the following description and indi-' cated in allthe views of the accompan ing drawings by the same reference numera s.

The improved paper clip forming the subject matter of the present invention is formed of a'single strip of spring metal, preferably the paper.

spring wire, an intermediate portion of which is bent to produce a spring clam ing loop or jaw 5, the wire forming one we 1 of the loop of jaw 5 being extended transversely across the opposite wall thereof and thence bent upon itself to produce a lateral projection or in 6, the wire being thence extended longitudmally within the lines of the loop 5 to Produce a second loop or jaw 7. The wire orming one wall of the loop 7 is extended across and beyond. the fulcrum bar 8 and thence bent laterally to produce a fingerpiece 9, the wire forming'one wall of the loop or jaw 5 being extended to form a similar fingerpiece 10. The free ends of'the. fin-.

ger pieces

9 and 10 are spaced apart and-deflected laterally so that when the same are pressed together the free or active ends of the

jaws

5 and 7 will be separated,-thereby permitting the removal of the paper., The wire forming the walls of the loop; 7 is bent to produce co-incident humps or'projections 11 adapted to grip the'paper when the latter is positioned between the

jaws

5 and 7 and thus assist in retaining the several sheets of paper in assembled position. The side walls of the spring pressed clamping jaw or 100 7 are slightly converged, while the reduce end thereof is projected longitudinally be.- yond the end wall of the loop or jaw 5 to form a lip at 12, so as to assist in guiding the sheets of. paper between the clampin jaws and thus facilitate the positionin o the clip on or removing the said clip rom One terminal 13 of the fingerpiece 9 bears against one side of the wire constitutin the fulcrum bar 8 while the other terminal 14 of the fingerpiece 1O bears against the other side of the fulcrum'bar 8. It willbe noted that the terminals 13 and 14of the finger pieces bear against the opposite sides of the fulcrum bar 8 thereby to prevent lateral tilting movement of said fingerpieces and thus maintain the clamping aws in pro er parallel relation to each other. Itwil also be noted that when an inward pressure is exerted on the fin er pieces9 and 10' the finger piece 9 will be tilted on the fulcrum bar- 8 and that as soon as the pressure is released from the finger- By-re ference to Fig. 1 of the drawings,

it will be seen that the projection or lug (5 rests upon the loop or jaw 5 and forms in effect a fulcrum for the jaw 7 while the bar 8 is interposed. between the

fingerpieces

9 and 10 so as to properly space the converging ends of the fingerpieces and thus facilitate opening and closlng of the jaws when an inward pressure is exerted on said fingerpieces.

While the humps or projections 11 are shown on the loop or j aw 5, it will of course be understood that said projections may be formed on the jaw 7 or entirely dispensed with if found desirable or necessary to effect the proper clamping of thesheets of paper. It will also be understood that the clips may be made in different sizes and when made relatively large may be used for clamping newspapers, magazines, and other articles and suspending same from a nail, hook or other suitable support.

Having. thus described my invention, what is claimed is:

1. As a new article of manufacture, a paper clip formed of a single piece of spring wire having an intermediate portion thereof bent to produce a substantiallyrectangular loop, the wire forming one side wall of the loop being extended in a straight line across said loop and in contact with and beyond the other side wall thereof to form a transverse bar, and thence bent upon itself and extending longitudinally to produce a second tapered loop of greater length than the rectangular loop, the wire forming the end of one of the loops being bent to produce a finger piece, the terminal of which bears against one side of the transverse bar, and the wire forming the end of the mating loop being bent to produce a similar finger piece, the terminal of which bears against the other side of said transverse bar, there being depressions formed in the side walls of the tapered loop and defining projecting portions extending laterally from the same side of the loop adapted to bear against and press the paper between the side walls of the rectangular loop.

2. As a new article of manufacture, a paper clip formed of a single piece of spring wire having an intermediate portion bent to produce a loop, the wire forming one side wall of the loop being extended in a straight line across the loop and in contact with and beyond the other sidewall thereof to form a transverse bar, and thence bent upon itself and extended longitudinally to produce a second loop of greater length than the first mentioned loop, the wire forming the end of one of the loops being bent to produce a finger piece, the terminal of which bears against one side of the transverse bar and the wire forming the end of the mating loop be ing bent to produce a similar finger piece, the terminal of which bears against the other side of said transverse bar.

In testimony whereof I aflix my signature in presence of two witnesses.
