PAPER-CLIP.

Specification of Letters Patent.

Patented Ma.1-.1e,192"o.

Application filed lkpril 18, 1917. Serial No. 162,920.

To all whom it may concern:

Be it known that I, J OHN M. DINWIDDIE, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Paper'Glips; and I do hereby declare the following to be a. full, clear, and exact description of the invemzion, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to clips and more Pttl'tlblllttl" to that class of clips especially adapted for holding or binding together two or more sheets of paper.

r-id'iother object of this invention to pro vide a novel type of clip, which can be readily and expeditiously placed in position on the articles to be held together.

A. further object of this invention is to provide a wire clip so formed as to provide a means whereby the same can be readily grasped to spread the clamping members, so that the paper or articles to be held can be conveniently inserted between tl'ie clamping members.

llhese and other objects will appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had to the accompanying drawing forming a part thereof, in which:

Figure l is a plan view of the clip, and

Fig. 2 is a. section taken on the line 2--2 of Fig. 1.

Referring to the drawing in detail, the improved clip consists of a single piece of wire bent to form an outer spring clamping member 1 and an inner spring clampin niei'nber 2 of ELPIHOXlIYRItGlY U-shaped formation. The inns and outer n'ieinl'iers have opposed legs connected by a bar 3.

The arms member 1 are arcuately bowed in opposite directions to provide an enlarged opening to permit of the insertion of the thumb of the operator between the arms t and 5. The terminals of the arcuate arms 4L and 5 are bent in diverging relation as at 6 and one of the terminals is connected to the bar 3.

The inner approximately U-shapod member 2 is provided with curved portions 7 and 8, which extend from the bight portion 9 and which are then bent arcuately in opposite directions to the arms 4 and 5 to provide 4; and 5 of the out-

er clamping arms

10 and 11. The terminals of the

arms

10 and 11 are diverged as at 12 and one of the terminals is connected to the bar 3.

The

arms

10 and 11 provide a bearing surface for the thumb of the operator so that the inner clamping member 2 can be depressed in relation to the outer member 1.

The outer and inner members 1 and 2 lie in the same plane and the inner member is spaced from the outer member at all points, so as to permit of the convenient insertion of the thumb of the user.

In use, the thumb of the operator is placeil on the

arms

10 and 11 of the inner member and the fingers are placed on the arms a and 5 of the outer member, and by drawing the thumb and fingers toward each other, the inner member is depressed, which allows convenient insertion of the papers and the like between the clamping members.

By virtue of having the inner and outer members spaced, the inner member can be readily depressed. without the thumb and lingers of the operator becoming engaged.

From the foregoing description taken in connection with the accompanying drawing, it will be seen that a novel type of clip provided, which can be readily applied to the articles to be held. and will effectively prevent the same from being displaced.

Having thus fully described my invention, what I claim as new is:

l. A. paper clip comprising an inner clamping member h avi n g a plurality of relatively spaced connected side arms, an. outer clamping member having a plurality of relatively spaced connected errors, and a member connecting one arm of the inner member to one arm of the outer member, iiuiermediate portions of the arms of the outer member be ing deflected outwardly to provide finger engaging portions and permit the passage of the thumb between. the arms for engagement with theinner member anifl to increase the gripping area of the outer member, all of said parts being located in the same plane.

A, paper clip comprising an inner clamping member having a plurality of rel a tively spaced connected side arms, an outer clamping member having a plurality of relatively spaced connected arms and a member connecting one arm of the inner member to one arm of the outer member, inter-median: portions of the arms of the outer n'iember being deflected outwardly to provide finger engaging portions and permit the passage large area of the paper enga d by the clip, 10 of the thumb between the arms, intermediate as and for the purpose specifizd.

portions of the arms of the inner member In testimony whereof I afiix my signature being deflected inwardly to provide thumb in presence of two witnesses engagmg portions and to prevent the passage of the thumb between the arms of the JOHN DINVVIDDIE' inner member, the deflected portions of the Witnesses: arms of the inner and outer members also H.

forming means for engaging a relatively W. J. ELLlo'rr.
