' 'cYRUs E. THOMPSON, or WINrIErD, KANSAS n rnriin CLIP invention relates to v`clips',l and pari ticularly to an `improved paper chp or lthe like. y y Q y; .It is an important object of the invention to provide a clip which can be applied to papers,b,ook pages, and othersmall objects at either end, and will securely retain the ob- 'ects. f J It is also an important obj ect of my invention to provide a clip' of this type which can be very cheaply manufactured from a. single length of wire with few and inexpensive operations. Y Other objects and advantages vof the 1n-` vention will b-e apparent from a reading of the following description and drawing, wherein for purposes of illustration have shown a preferred embodiment of the invenf v tion.

In the drawing Figure 1 is a general side elevational view of the embodiment.

Figure 2 is a bottom plan view of Figure l. Most paper clips and the like must be engaged with the papers and the like at one end only, and this one end does not always securely hold the papers either because the cost of providing a sufliciently strong clip is f prohibitive or the construction of the clip is such that it is diicult to apply and will not securely hold the objects to which it is applied. Usually, clips which are efficient are expensive and for that reason are not in deg mand where a low priced clip is sought. The device of the invention is so constructed that it may be made of fairly low cost material in a very simple manner, and yet be capable of being readily and quickly engaged with 1 the papers or the like, and will then securely hold the papers or the like. This accomplishment will be better understood upon reference in detail to the drawing, wherein like numerals r-efer to like parts throughout the l same. The numeral 5 generally designates the embodiment described.

A single length of wire of suitable gauge, is bent at its middle completely in a circle whereby the single convolution 6 jis produced 1 1 together with the returnrbends 7, 8 from which continue the straight legr 9 in a con- .application inea April' 1.1,

'Where the end portions of the legs 9, 10 come together or. converge their touche 55 ing vfaces `are provided with nicksrorroughened cooperating surfaces as indicated dat' 11 for increasing the frictional grip 'of these portions of the legs. Fromtli-e point ll'the extremity of the leg 9 is extendedj outwardly in a curved mannerasindicated at 12,` while the, corresponding portion (of the legrlOis similarly oppositely extended andcurved as indicated at 13but'tfhe portion 13 ofthe'leg 10 does not extend outwardly. quiteas far. as does the extension 12 Vof the leg 9.- r n Y Reference to Figure 2 will; disclose that the portion of the legl() extending beyond the point 13 isrcurvednat 14 whereby toform a` U-shape which terminates at'15 abeveothe 70 leg 9'whence the remaining Y'portionlof the. leg' 10 is transversely and angularlyrdirected. in a straightline as indicatedat 16r and .overlapped on the outward. side` offrtlieA leg 1() 'as y., indicated at 17. 4 .i 75 f A similar and oppositeforination is given the"icorrespondinggpart of the leg 9. How-i' ever, the formation takesl a slightly different. shape in ,the caseofthevleg y9, since instead of being curved as isthe leg l() at 13 and 14, the leg`9` is not yquite ,so curved, but has a squared portion 181whichexte`nds beyond the endof the portion ,14 asy already indicated ,in previous description.V VThe straiglitportion of the leg 9 Vis overlapped on the outsidecof the leg 9 at the point 19 just abovethepoifnt indicatedfat 17 onthe'leg 10. l r1 VIt willi'be observed .that the return bends 7, 8 andthe c'onvolution` maybe spreada and; papersv or 1the like inserted therein whereby to be `securely held.

It'will be observed that a busy nians time is considerably saved as well as his patience, since he can readily clip together papers by inserting them at the end of the clip, making it unnecessary lto adapt any special technique in engaging the clip, or using both hands for this operation.
