Specification of Letters Patent Patgnted F b 2 1 2 Application filed December 13, 1920. Serial Nuisance.

To allwhom it may concern:

Be it known that I, JENs NIELSEN,-

citizen of the United States, residing at Chicago, Illinois, have invented certain new and useful Improvements in a Pencil Clip;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to clips as used for detachably retaining pens or pencils in pockets, and more particularly to a clip of this kind arranged so that it can readily be released by the pressure of a finger on one end of the spring-pressed tongue which clamps the holder to the wall of the pocket when it is in use. For this purpose, my invention aims to provide a novel construction which will permit the easy and speedy assembling oftheparts in firmly united relation to one another, and which preferably will also permit the use of a spring made of a stifiermaterial than that demanded by the forming operations as required both for the tongue of 'the clip and for the band portion which encircles the pen .orf'pencil A More particularly, my invention aims to provide a construction for this purpose in which the band portion is firmly interlocked with the resilient portion during the forming of the band, and in which the firm in terl'ocking of. these parts can. readily be obtained without notching or, otherwise in-' denting the spring. It also aims to provide a simple method for assembling such parts in firmly united relation to one another without employing rivets or other auxiliary fastening elements. Still further and more detailed objects willappear. from the following specification and from the accomanying drawings, in which i Fig. 1 is a side elevation of a pencil clip embodying my invention, showing'the same as used on a pencil and'indicating in dotted lines the position of a hand releasing the clip from a pocket.

Fig. 2 is a perspective view of the band portion of the clip.

Fig. 3 is a perspective view of the stem portion or pressure arm of the clip before this portion is attached to the spring.

Fig. 4 is an enlarged transverse section through the band portion of the clip taken along the correspondingly numbered line of Fig. 2.

Fig. 6 is an enlarged bottom view of the same blank, also having dotted lines to show tne curvature-into which the wings of the blank are afterwards formed.

, Fig, 7 1s perspective view similar to Fig. 3 but showing another-typeof stem for a pencll clip embodying my invention. Fig.8 is a band member suitable for another embodiment of my'inventiom namely one in which the spring is lntegral with the band and in which the free-portion of the spring is recessed to interlock with the wings on the stem of the proposed clip. L

V In constructing a pencil .clip after the manner of Figs 1 to fi inclusive, I first form a blank outj of resilient sheet metal such as brass or steel, which blank has a-central back 1 and a pair of -lateral wings 2 at opposlte sides'thereof. 1 I also form from the b'aolrl at least one strip- 3 extending transversely'of the back and raisedirom the said back by" asufiicient distance topermit the ready sliding of one end or a spring 4 be} tween the same, thereby producing what is shown ln Fig. 5. The spring 4 desirably consists of a flat piece of strip spring steel,

pl 'shi P- i I also (and desirably by punch press operations) hlank and form the stem or pressurearm-for. the clip, which stem desirably comprises a shank 5 terminating in a ball 6 atits lower end and in finger engaging tip 7 at its upper end, and having afpair oi lateral wings 8v disposed at opposite sides of'it and at a relatively short distance from the'upper end 7. I then secure the spring 4 to thisstem by turning the wings 8 over oneend or the spring so as to clamp this portion of the spring between them after the manner of Fig. 4:, this being readily done by a simple punch press operation. After the stem has thus been rigidly secured to the spring, I slip the other end of the spring between the back 1 and the strap or straps 3 of the band member of the proposed clip, or into the position of Fig. 6, after which subject the band to the forming operation which gives the curves its wings into the shape shown in Fig. 4. Din

perspective view showing a ing this forming operation the portions of the straps 3 which connect therear thereof with the wings 2 will tend to curve into alinement with these wings, and will also tend to curve the interposed portion of the spring, thus causing the ends of the strap of the stemwhere this can readily be reached by a finger of the hand grasping the pencil,

' so that the clip can easily be released from a pocket by: pressure exerted between the thumb and the forefinger after the manner shown in Fig. 1. Moreover, since I can make-the spring portion of a material which could not be formed to shapes such as those required for either the stem orthe band por tion of my clip, I can obtain a permanent and high resiliency in the spring. Likewise, since no notching, perforating or other indenting of the spring is requlred, this part is very cheaply manufactured; and since no rivets or other auxiliaryfastening members are needed, the entire cost of the clip can be kept quite low. I am therefore able to pro.-

"L dime a pen or pencil clip'at a low cost, while providingboth durability and a high degree of permanent resiliency and while permits ting the resulting clip to be manipulated with case when the pen orpencil is to be inserted in a pocket 10 or withdrawn from the latter. 7

However, while I haveheretefore described my invention in a highly desirable embodimentflmd have pictured the same in an ornamental form including a ball tip 6 for the stem, and an ornamental opening the wings of the pocket member, I do not wish to be limited to these or other details of the 7 construction and arrangement thus disclosed.

(after the manner shown in Fig. 7), as a substitute for the ball 6. Likewise, the ornamental openings in the wings 2 of the bandmember might be omitted as shown in Fig. 8 and the spring might be made integral with this band after the manner shown at 9 in the same'figure. So also, the resulting shank 9 ofthis member might be laterally notched as shown in Fig. 8 for interengagement with the wings 8 on'the stem member of the clip, although I have not found such a notching necessary for securing a firm interlocking when assembling my clips after the general manner a'bove'described. 1

I claim as my invention:

. 1. In a pencil clip, a pressure member, a resilient intermediary element fastened at one end to the pressure member, and a band member adapted to grip a pencil andfhaving a pairof strap portions struck up therefrom and spaced longitudinally of the'pen'cil and cooperating in clamping the, other end of the intermediary member rigidly tothe band member. f

2. In a pencil clip, a pressure member, a: U-

shaped spring secured at one end thereto,.

and a pencil-gripping member having a pair of strapsstruck up from the same and prey senting" loops alined longitudinally" of the pencilgripping member and. the 'pencil-. gripping member, the spring having one shank extending through both straps and the said straps being curved substantially. concentric with the back of the pencil grip} ping member to clamp'the' said shank ofthe spring rigidly to the penCiI gr'ipping member. 1

3.71s. the manufacture of a pencil} clip having a U-shaped spring attached at one,

end to its pressure member, thelmethod of securing. theother end. of the spring immovably to the pencil-banding. member which consists in slidably' inserting this: lat ter end of the springbetween suitably spaced portions of the pencil-bandingmember while the latter has. its main parts fiat and amp: I
