run on PENCIL CLIP.

"Application filed August 10, 1926. Serial No. 128,348.

7 carried in the pocket and the principal objects of my invention are to generally improve upon and simplify the construction of the existing forms of pen or pencil clips; to provide a clip having a double spring element that is effective in materially increasing the gripping engagement between the clamp and pen or pencil and between the pen or pencil and the portion of the clothing to which it is temporarily secured; and further, to provide a device of the character referred to that is inexpensive of manufacture and which may be easily produced by reasonof the fact that it may be struck or stamped from a single piece of material. 1

With the foregoing and other objects in view, my invention consists in certainnovel features of construction and arrangement of parts that will hereinafter be more fully described and claimed and illustrated in the accompanying drawing, in which- Fig. 1 is a perspective view-of a portion of a pencil and showing a clip of my improved construction applied'thereto. I

Fig. 2 is a vertical sectiontakenlengthwise through the center of the clip and showing the normal positions of. the spring arms that form a part of said clip.

Fig. 3 is a vertical section taken lengthwise through the center of the clip and showing the positions assumed by thespring arms when the clip is applied to a pen or pencil. I

Fig. 4 is a horizontal section taken on the line 4-4: of Fig. 1.

Fig. 5 is an elevational View of a modified form of the clip.

Fig. 6 is a vertical section taken on the line 6-6 of Fig. 5.

Fig. 7 is a vertical section taken on a central plane through the'upper portion of a further modified form of the'clip. i

As illustrated, my improved clip is formed from a single piece of material, preferably sheet metal that has a certain amount of resilience. The main body 10 of the clip comprises a short vertically disposed member that is substantially semi-circularor horse shoe shaped in horizontal section and of such sizeas to receive 'the'body of a penor pencil.

The lower p'ortions-of-the sides of-this semi-circular body are extended downward as designated by 11 so as to form on the free edges of' the side portions of the body 10 elongated pen or pencil engaging ears 12, and which latter, it will be understood, yieldingly bear on the surface of the pen or pencil and retain the same in the semi-circular or horse shoe shaped body 10.

Depending from the intermediate portion of the body 10 is a narrow strip of resilient sheet metal 13 that functions as a spring and the lower portion of this spring member is curved gradually outward as'designated by 14. From the lower end of this outwardly curved portion 14; the strip of metal extends inwardly, thence upwardly to forma secondary or supplemental spring 15, the width of which is approximately the same as the width of spring member 13, and the upper portion of thesupplemental spring member 15 extends through the body 10 of the clip,

and said upper portion is curved gradually outward toward the'ears 12, as designated This outwardly curved upper portion of I the supplemental spring is designed to yieldingly engage the pen or pencil and to normally press the same against the ears 12.

.The upper end of the supplemental or secondary spring 15 terminates in a plane that is practically coincident with the plane that is occupied by the top of body 10.

Under normal conditions, or before the clip is applied to a pen or pencil, the double spring or the

members

18 and 15 occupy the positions as illustrated in Fig. 2, and when the clip is positioned upon a pen or pencil, the curved upper end 16 of spring member 15' is necessarily forced inwardly toward the intermediate portion of the body 10 and the engagement of the ears 12 with the body of the pen or pencil causes the lower portions of the

spring members

13 and 15 to flex slightly outwardrelative to their normal positions with the result that the face of the inner member 15 bears with a considerable degree of pressure against the pen or pencil body at a point a short distance below the points of engagement between the cars 12 and the pen or pencil.

The pressure of the upper portion 16 of spring member 15 against the pen or pencil cooperates with the yielding pressure exerted by theears 12 in firmly anchoring thejclip front of a pocke t, fis passed betweenthe douill ble

spring members

13 and 15 and the body of the pen or pencil, the portion of the garment will be very securely clamped between the double spring members and thebody of the pen, or pencil, thereby ell'ectually preventing accidental disengagement and loss of the latter.

Formed integral with the upper edge of the clip body 10 and at the center thereof is an car 17 that is bent inward and this ear terms a bearing and stop for the upper end ot the auxiliary spring 15, when the latter is forced inward by the inserted pen or pencil (see Fig. 3).

The bearing of? the end of spring 1? against the ear it tends to increase the pressure of the curved portion 16 against: the pen or pencil when the latter is positioned in the holder.

In the modified construction illustrated in F and 6, the substantially semi-circular body of the clip is provided with a single depending spring member 17 that is adapted to bear against the engaged pencil a. short distance below said body 10 and stamped from the upper portion of the spring 17 and the central portion oi the body 10 is a spring tongue the upper portion of which normally extends upwardly between the cars 12 onthe sides of the body l0. \Vhen this form of clip applied to a pencil. the "free end of tongue is pressed rearwardlv within the body 10 and the pressure thus developed cooperates with the resilient cars 12 in clamping the clip to the engaged pen or pencil.

1n the modified construction illustrated in Fig. 7', a resilient tongue 19 is formed integral with and'extends downwardly from the intern'iediate portion of the clip body it)" and when this term of clip is applied to a pen or pencil, tongue 19 is pressed rearardly and the resulting tension presses the, engaged pen or pencil against the resilient ears on the sides of holder l0 so as to Vtlfy securely grip said pen or pencil and secure the clip thereto.

Thus it will be seen that l have pro vided a pen or pencil clip that is relatively simple in construction. capable of being easily and cheaply produced and which is'rery effective in performing the functions for which it is in tended.

It will be nnde stood that minor changes in the size, form and construction of the various parts of my improved clip may be made and substituted for those herein shown and described without departing from the spirit of the invention, the scope of which is set forth in the appended claims;
