'a claims.

This invention relates to a paperv clip and more particularly to atype thereofwwhich is adapted to be used as an advertising medium or a means of identification.

sheet of material of any character with a convoluted wire clip so that a plurality of papers may be removably-secured together; the sheet of material having a legend or identication means carried thereby.

A further object of the invention is to provide a paperclip having a sheet of material associated therewith in such a manner that the assembled structure may be continually used without injuring the assembly as a unit.

An additionalobject of the invention is to provide a portion of the sheet of material so that it will be reinforced against longitudinal stresses transmitted thereto during service. 0 The above and numerous other objects will become apparent from the succeeding description considered together with the accompanying drawing which illustrates an exemplii'lcation of the present invention and wherein:

g5 Figure 1 showsa front elevational view of a convoluted wire member or clip.

Figure 2 shows an elevational view of a sheet of material removed from an assembled unit.

Figure 3 shows the relation between the mema0 beroi' Figure 1 and the sheet of material of Figure 2 before they are secured together.

.Figure ishows an assembled clip or member embodying a form of the present invention.

Figure 5 is an enlarged horizontal sectional view taken along the lines 5-5 of Figure 4, looking in the directionof the arrows.

Figure 6 is an enlarged vertical sectional view taken along the lines 6-6 o1' Figure 4, looking in the direction ofthe arrows. l

y,Referring now in detail to the drawing, wherein like reference charactersv designate'like parts,

n the numeral I indicates generally a conventional form vof paper clip employed to be interlocked with the marginal edges of two or a plurality oi'` f' tive oi the type which may be employed and is not A intended as a limitation .of the present invention. 5o Numerous-other. types of clips may be employed withthe same advantages enjoyed as by the use of the illustrated clip. g As is common with clips of the character under immediate consideration, the 'clip is formed .of

' wire and presents an inner convolution land an An object of the invention tol arrange al outer convolution 3, both of which are disposed 1n a common plane and may be moved-transversely or away from one another to present an opening for the insertion of a single or a plurality of sections oi' paper therebetween. 'I'he outer convolu- 5 tion is, by reason of itsextending around the inner convolution, of greater dimensions than the inner convolution, and for this reason its free extremity 4 is in spaced relation to a corresponding or free extremity 6 of the in nerconvolution. 10 The inner and outer convolutions are joined or integrally connected by a loop or arcuate portion 6 forming the extremity of the clip opposed from the convolution extremities 4 and 5.

A sheet of material, generally designated by l5 the numeral l and illustratedin Figure 2- as it appears before assembly with the clip, is elongated or rectangular in form and is of a width slightly greater than the over-all width ofthe clip outer convolution 'for the purpose to be hereinafter 20 explained. The sheet 'l may be of a transparent cellulose compound or, if desired, may be formed of a relatively thin durable paper, no particular character of material being at present preferred.

Consideration has been vgiven to the serviceability of the assembled' unit, and therefore the' sheet has been shaped so that it may only overlie one side of the clip, leaving the other side thereof substantially free in order to eliminate a constant wear to which it mayotherwise be subjected in service. It will, of course, be understood that if the sheet were to extend completely or substantially so about a convolution'of the clip i'rlctional forces would be created on a line contact between the enveloped convolution and the adja- 35 A cent paper of the plurality thereof' being secured together. These frictional forces would result in the severance of the sheet oi.' material along the line contact referred to and the unserviceability of the assembled clip for the purpose for which it was designed and intended. Also, ii the sheet of material were to'envelop a portion of the outer convolution, theenvelope could only extend to the proximity of the free extremity 5 loi! the inner convolution for, if it were extended further longitudinally of the clip so as to envelop the inner convolution, the assembly could not be used since the two convolutions could not be spread apart for the reception of a single or a plurality of sections of paper. 50

For the above-enumerated reasons, therefore,

' the sheet of material is made of a width so that, upon application thereof to a clip, it will extend across a. single side of the outer convolution and the lateral free edges 8 of the sheet will only 1 extension or prong I 'I extend about-and be in intimate contact with a segment, preferably a quarter, of the wire, as most clearly illustrated in Figure 5 of the drawing. The segment of the sheet, which bears, against the portion of the wire forming the outer convolution, is secured thereto by means of a gum compound, which has been found to be desirable when the sheet is formed of a cellulose compound, or any preferred adhesive. Since the sheet is to carry a legend, illustrative of which are the letters appearing thereon in Figure 2, it is desirable to obtain a relatively large area for the accommodation of the legend, and for the -accomplishment of this purpose the sheet extends longitudinally of the outer convolution for substantially the entire length thereof.

It has been found that unless the extremity of wrinkling of the sheet an extremity is, therefore,

cut inwardly toward the center line lthereof to present tapered or inclined edges 9 which, when the sheet is assembled with the clip, reference being had to Figures 3 and 4, extend across the extremity 4 to leave portions thereof disclosed. The inclined edges 9 of the sheet merge into substantially parallel edges I0 of the sheet which are spaced apart a distance less-than that between the lateral free edges 8 to thereby form a tongue, 'I'he prong is wrapped around the free extremity of the outer convolution to present a reentrant member which .is secured by any approved means, such as the previously mentioned adhesive, to the free extremity of the outer convolution and the reverse side of the sheet. This prong construction and its association with the clip afford a means whereby the adhesive securing the side marginal edges of the sheet to the outer convolution is relievedof longitudinal stresses to which it might be subjected during service of the clip. The prong extending to what may be termed the reverse side of the clip is not objecuonabiefsmce, in actual service, it rarely happens thrft/ the free extremity of the outer convolution comes into intimate contact with the papers to be attached or maintained in assembled relation, and hence it would not he subjectedto frictionalforces to which reference has been previously made.

It will,- of course, be clearly understood that various changes and alterations may be made to y the illustrated and described construction without departing from within the spirit and scope of the appended claims.

I claim: v 1. In combination with al wire clip formed by encaisse an inner and an outer convolution positioned in a common plane and having free extremities of the convolutions spaced from one another, a rectangular sheet of material adapted to carry a legend and being of a width slightly greater than the width of the outer convolution and of a length substantially equal to said outer convolution, the sheet having longitudinal edges thereof extending around and secured to only a quarter segment of the wire forming the outer convolution, and a prong extending from one end of said sheet intermediate said longitudinal edges; said prong being adapted to be secured tov said free extremity of said outer convolution and said sheet intermediate the planes of said longitudinal edges.

2. In combination with a wire clip formed by an inner and an outer convolution adapted to be separated for attachment to a marginal edge of a section of paper and having free extremities of the convolutions -spaced from one another longi- 20 tudinally of the clip, a sheet of material adapted to carry a legnd and being of a width slightly greater than the width of said outer convolution and of a length substantially equal to said outer convolution, said sheet adjacent longitudinal' edges thereof extending around and being secured to only a segment less than half the circumference of the wire forming said outer convolution, sloping edges on said sheet extending inwardly from said longitudinal edges and extending across the free extremity of said outer convolution, and substantially parallel edges of said sheet merging with said sloping edges defining a prong therebetween ;'said prong being bent around said` outer convolution free extremity and secured to said sheet.

3. In combination with a wire clip formed by an inner and an outer convolution adapted to be separated for attachment of the clip to a marginal edge of a section of paper and having free extremities of the .convolutions spaced from one another longitudinally of the clip, a sheet of material adapted to carry a legend and having a width slightly greater than the width of said outer convolution and of a length substantially equal 4.5 dto said outer convolution, said sheet extending across said outer convolution and having portions adjacent longitudinal edges thereof extending around and being secured to a segment of the wire less than half the circumference of the wire forming s aid outer convolution, inclined edgesvextending inwardly of said sheet from said longitudinal edges, and substantially parallel edges of said sheet spaced apart a distance less than said longitudinal edges forming continuations of said inclined edges to dene an extension therebetweensaid prong being bent around said outer convolution i'ree extremity and extending ina direction toward the free extremity of said inner convolution-to be attached to said sheet.
