March 14, 1939. w. P. WILLIAMS I CARD HOLDER FOR LOOSE LEAF BINDERS Filed March 22, 1937 IN1/EN TOR.
Patented Mar. 14, 1939 UNITED STATES PATENT OFFIQE Application March 22,
This invention relates to a card holder for loose leaf binders.
The principal object of this invention is the provision of a transparent pocket in the cover of a loose leaf binder so that a card may be inserted therein. A further object of this invention is the provisio-n of a transparent pocket built into the cover material of a loose leaf binder, thus forming an inherent part thereof.
A further object of this invention is the provision of a transparent pocket that may be applied to the cover of a loose leaf binder, if and when desired.
With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the comb-ination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.
The invention is illustrated in the accompanying drawing, wherein:
Figure 1 is a perspective view of the top half of a loose leaf binder showing a transparent pocket therein.
Figure 2 is a cross section detail of the construction shown in Figure 1.
Figure 3 is a cross section detail of a modification in the construction and application of the invention.
By referring to Figure 1 of the drawing it will be seen that I have devised a simple, yet practical and efficient means for carrying a card on the front cover of a loose leaf binder. The loose leaf binder comprises a front cover I and a back cover 2. A number of loose leaves areshown by numeral 3. 'Ihe method of holding the leaves is represented by the ring 4 positioned in an eyelet 5 of the binder. The cloth 6, or other binding material, has an opening 'l therein. A recess 8 has been formed in the cardboard 9 or other material used in the binder cover, and a doubled piece of celluloid Ill has been positioned therein. One upper end II of this doubled piece of celluloid is stitched or glued to the cover material 6, and the lower U-shaped section I2 of 1937, Serial No. 132,201
this doubled piece of celluloid is likewise stitched or glued to the cover material 6. The other upper end I3 of this doubled piece of celluloid is provided with a reinforced edge. This doubled piece of celluloid is also stitched or glued at both 5 sides, thus forming a transparent pocket within the cover itself. Any card may be readily inserted in this transparent pocket. The pocket is particularly adapted to hold a class program card, as the card is instantly available for any 10 changes necessary and is visible at all times for reference thereto.
A modication of my invention is shown in Figure 3 of the drawing in which a section of a loose leaf binder is shown formed of the usual l5 cardboard I4 and binding material I5. In this modification the transparent pocket has been applied, by any convenient method, to the surface of the binding material I5 on the cover of the loose leaf binder. In this modification the transparent pocket comprises a doubled piece of celluloid I6 and a frame I1 of any suitable material. This form of pocket is adapted for application to covers already manufactured.
It is obvious that any suitable transparent material may be used in place of celluloid, if desired.
What I claim is:
1. A card holder for loose leaf binders and the like comprising a doubled piece of celluloid positioned in a recess in the cover of said loose leaf binder, a reinforcement on one edge of said doubled piece of celluloidand the other edge firmly secured to the binding material of the cover in such manner that the entire doubled piece of celluloid forms a pocket within the said recess, the said doubled piece of celluloid being stitched or otherwise fastened at each side thereof to the binder. l
2. In combination with a loose leaf binder 40 cover, a transparent pocket comprising a doubled section of transparent material, one edge of which is extended in relation to the other, said transparent material having a frame inclosing the edges thereof, the said relatively short section of transparent material being left open to form a pocket, said frame and pocket attached to said loose leaf binder cover by stitching or other suitable means.
