PAPER-CL1P.

Specification of Letters Patent.

Patented March 20, 1906.

Application filed March 2,1905. Serial No. 248 605.

To all whom it may concern:

Be it krmvn that l, Hanorn E. HAWKINS, a citizen of the United States, residing at Kansas City, in the count}- of Jackson and State of Missouri, have invented certain new and. useful Improvements in Paper-Clips, oi which the following is a specification.

My invention relates to improvements in paper-ell is; and my object is to irovide n device ol this character which will reliably hold either a small or a large number of papers together without losiligjts resiliency or clamping power.

The invention consists in the peculiar formation of the clip, and in order that it may be fully understood reference will now be made to the accompanying drawings, in which Figure I is'& plan view of the clip, showing the normal position'ol' its clamping members in full lines and the operative position oi said members in dotted line. Fig. 2- is n rear elevation of the clip, showing its clamping members in their normal position. Fig. 3 is a rear elevation of the clip, showing its members in an o erative position. Fig. 4 represen ts a side 0 ovation of the clip with its clamping members occupying their normal position.

the clip applied to a bundle of pa. ers Fig. 6 represents a modified form 0 t 1e clip applied to a bundle of papers.

In carrying diit the im'ention I employ a sin le piece of spring-wire formed into a pair of ongitudinal clmnping members I, having upturned forward terminals 2 and humps or raised portions 3, located between terminals 2 and their downwardly-bent rear ends 4. Sold members 1 are preferably arranged parallel to each other, as shown.

5 desi notes a pair of transverse members, arranger in alinenient in plan view, which communicate at their outer ends with bent portions 4 and at their inner terminals with the two crossed ends 7 of a forwar ll -'-extending clamping member 6, arranged in the form of a diamond-shaped loop, located between clamping members 1 and terminating a slight distance in the rearof terminals 2, as plainly shown in Fig. 1.

In applying the clip to a number of papers the edges of the latter are slipped in between clamping members I and loop 6, so that the letter will press downwardly upon" said papers, while terminals 2 and humps 3 will ongage the under sidefof r .id papers, and thus Fig. l and full lines in Fig. 3.

Fig. 5 represents a side elevation of,

reliably hold them together. The tension of the clip upon the papers is also increased by the spreading apart of the clamping members to receiv. said papers. This spreading ex ponds loop 6, draws clnmpin members 1 toward each other, and causes t e inclination of members 5, as shown by dotted lines in p The contraction of the loop alter the clip is removed from the papers causes the other members of said all i to resume their normal positions.

lhe capacity of the clip may be enlar ed by increasing the length of the downwar ybcnt portions 4, as indicated at 4, Fl 6, as the clamping members i and 6 may t ion be spread a considerable distance apart without affecting their resiliency or ripping action.

The advantages obtained in turnin terminals 2 upwardly are, first, that they will reliahl grip the under surface of the bundles to which the clip is attached, and, second,\vill not project in the we r and on age another package of papers lai beside t ie one upon which the chp is secure Humps 3 odd to thefrigidity of clamping members 1 and also slightly crimp the papers to which the clip is attached, thus preventing said papers from accidentally slippin outwardly from between clamping mom are 1 -and 6, and by crossitlg the rear ends of the latter in the manner shown in Fig. 1 its rigidity is also greatly incijeased, as one end reinforces the other.

From the above description it is ap arent that I have produced a paper-clip w iich is durable, simple in construction, and thoroughly efi'ect-ive for the urpose intended.

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

1. A paper-clip consisting of a pair of longitudinal clamping members hsvin downtnrned rear ends and humps located etween said rear ends and the lorwsrd terminals of said members, transverse members communicating with said rear ends, and another clamping member arranged in the form of a. loop having, crossed terminals communicating with the inner ends of the transverse members.

2. A paper-clip consisting of a pair of iongitudii'ial clamping members havin upturned forward ends and downturnet rear ends, transverse members communicating with said rear ends, and a diamond-shaped loop having two crossed ends communicating with the inner terminals of the tXIlHSVGIsO members.

3. A paper-clip comprising a pair of parallei ciampin members having upturned forward ends, ownturned rem ends, and humps located between said forward and rear ends; transverse members communicating? with the rear ends of said clumping niem )ers, and another clamping member arranged in the form of a loop having crossed terminais oommunicating with the inner ends of the transverse portions.

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