Description

March 12, 1957 G. T. WATSON PAGE CLIP Filed Jan. 18, 1954 INVHVTOR. Goeoou 7. IVATJON PAGE CLIP Gordon T. Watson, Los Angeles, Calif.

Application January 18, 1954, Serial No. 404,694

6 Claims. (Cl. 24--66) This invention relates to clips and more particularly to an improved clip for holding book pages in a relatively flat position.

Various types of paper clips, clip boards, page markers, and so forth are well known in the art. None of these clips however are adapted to accommodate anywhere from one to several hundred pages in a book and adequately secure these pages to one fly leaf of the book. Further, present day clips will not permit removal or insertion of one or more pages without having to expand and, in some instances, remove the clip each time. There is a strong need accordingly for a clip free from the above noted disadvantages, particularly in the case of field manuals or record books employed out of doors Where gusty winds tend to flap open pages in an annoying manner.

The present invention is primarily concerned with the provision of an improved clip for book pages which is economical to manufacture and assemble, easy to operate, and reliable.

More particularly, it is an object of the invention to provide a clip especially suited for use with field manuals or books to be used out of doors and which is capable of accommodating a large or small number of pages.

Still another object is to provide a clip which will not slip out inadvertently from the book and yet is easy to insert into position.

Another object is to provide a clip which will permit pages to be turned and slipped under the clip or removed from under the clip without having to expand the clip appreciably or remove the same.

Yet another object is to provide a clip of the above type which will not protrude to any appreciable extent from the edges of the book when placed in position, whereby the clip may simultaneously serve as a book marker.

These and further objects and advantages of the present invention are attained by providing a clip having as its primary component, an L-shaped member. The

horizontal leg of this member is adapted to slip under the fly leaf of the book or manual or under the bottom few pages thereof, and the vertical leg is adapted to serve as a rest or back surface seated against the edges of the pages to be clipped.

A clamping element is pivotally mounted intermediate its forward and rearward portions to the vertical leg of the L-shaped member. This pivotal mounting is disposed a suflicient distance above the angle in the L-shaped member so that a relatively large number of pages may be accommodated under the clamping element. A resilient means is disposed between the rearward portion of the clamping element and the vertical leg of the L-shaped member whereby the forward portion of the element is urged against the horizontal leg. Rocking motion of the clamping member takes place in the plane including the vertical and horizontal legs of the L-shaped member 2,784,470 Patented Mar. 12, 1957 andthe construction is such that a considerable separation or gap between the clip jaws may be effected.

The horizontal leg of the L-shaped member is provided along its longitudinal edges with barbs, these barbs being directed away from the free end of the horizontal leg. This arrangement permits the horizontal leg portion to be readily slipped under pages in a book but not easily removed unless the pressure of the clamping element is released.

Suitable finger grips for operating the clip are formed from integral portions of the vertical leg of the L-shaped member and the clamping element respectively whereby simplicity and economy are realized in the manufacture of the clip. Preferably the extreme tip end of the forward portion of the clamping element is turned upwardly in a smooth curve permitting pages to be readily inserted thereunder. In this action, the page edges themselves serve to expand the clamping element away from the horizontal leg to accommodate the inserted pages.

A better understanding of preferred embodiments of the present invention will be had by referring to the accompanying drawings, in which:

Fig. 1 is a general perspective view illustrating a preferred manner of using the present invention;

Fig. 2 is a perspective view of the clip shown in Fig. 1;

Fig. 3 is an elevational view partly in section of the clip of Fig. l in closed position;

Fig. 4 is a view similar to Fig. 3 showing the clip in open position;

Fig. 5 is a perspective view of a clip similar to that shown in Figs. 1-4 but embodying a modified type of pivotal mounting;

Fig. 6 is an elevational section of the clip shown in Fig. 5;

Fig. 7 is a cross-section taken in the direction of the arrows 77 of Fig. 6;

' Fig. 8 is a perspective view of another embodiment of the invention; and,

Fig. 9 is a section taken in the direction of the arrows 99 of Fig. 8.

Referring to Fig. 1, there is shown a book or manual 10. Books of this nature are oftentimes employed in the field for keeping records, making out receipts, entering orders, and so forth, and are often exposed to the elements rendering it difficult to adequately secure the pages in an open position.

In accordance with the invention, there is provided an improved type clip member, designated generally by the numeral 11, for holding down the book pages 12. As will become clearer as the description proceeds, the clip member 11 is so designed that it is a simple matter to manually insert further pages, such as the page 13, under the clip 11 without having to remove the same. Similarly, it is easy to slide pages out from under the clip. 1 Fig. 2 illustrates an enlarged perspective view of the clip 11 Essentially this clip comprises an elongated base member 14, which may be tapered in width towards its free end if desired. 7 The other end of the base member is bent upwardly to form a back member 15. Preferably the back member 15 extends upwardly at sub: stantially a right angle to the base member ld whereby a substantially L-shaped member having vertical and horizontal legs results. p

Cooperating with this L-shaped member is' a clamp ing element 16 having a rearward portion 17 of somewhat narrower dimensions to provide stop shoulders 18' and 19. This rearward narrowed'po'rtion 17'is adapted to fit loosely within a horizontal slot 20 in the back member 15, the slot being dimensioned to permit a rocking or a'pivotal motion of the clamping element 16 in the plane of the base and back members 14 and 15. l A resilient means, preferably in the form of a compression rilosedslierein'but is tozbe accorded the full scope of the claims-,so as wto ,embrace any and all equivalent devices. fHaving described ourinvention, what we claim as new and desire to secure by LettersPatent is:
