CHARLES l. BTZ, OF ST. LOUIS, MISSOURI.

Application filed January 7, -1929.

My invention relates to improvements in loose leaf` binders, and has for its primary object a loose leaf binder which is readily adjustable for a varying number of pages.

A further object is to construct a loose leaf binder in which the pages are securely held and in which no screws, rings or springs are employed for holding the pages.

A still further object is to vconstruct a loos-e leaf binder in which the pages can be readily removed and new pages inserted without the necessity of employing tools for that ur ose. f l A still further object is to construct a loose leaf binder having a flexible back, which back is formed of one piece and is adjustable for various thicknesses of book.

In the drawings:

Fig. 1 is a top plan view of my device withv parts broken away.

Fig. 2 is a fragmental view of the book inopen position showing the manner of releasing the page holder.

F ig. 3 is a section of Fig. 1.

Fig. 4l is an enlarged fragmental edge view of the binder.

Fig. 5 is an enlarged section taken on the line 5-5 of Fig. 1.

Fig. 6 is a perspective view of one of the back clamps employed. l

Fig. 7 is an enlarged cross sectional view of the page holder.

Fig. 8 is a perspective view of a modified construction of cover showingthe holding taken on the line 3-3 members partially inserted in the pocket and the page holder members in perspective on said cover and partially assembled.

Fig. 9 is a perspective view of the cover with tbe page holding members assembled yand in position thereon and one of the securing members ready to secure the page holding members together; and

Fig. 1() is a perspective view of one of the holding members.

In th-e construction of my device I employ a cover having a front member 8 and a back member 9. These members are preferably made stiff and are connected together by a flexible strip 10 which forms a hinge between the two covers so that the same can be opened without breaking over the cover. Passing partially around the back or hinge 10 are back clamps 11, which a-re in the form of doubleended books and which when placed in posi- LOOSE-LEAF BINDER.

tion on the back form a pocket 12 for the reception of tongues 13 of the holding members 14. These holding members are substantially U-shaped and are provided on one end with wings 15. Located within the cover are page holders 16 and 17. These page holders are substantially L-shaped in crosssection and have their ends 18 and 19 bent back upon themselves so as to form passageways 20 into which the wings 15 pass. Y

Carried by the turned-in portion 18 is a pin 21, which lits within a sleeve 22 carried by the turned-in portion 19.

It will. be noted that the members 16 and 17 overlap so that the pin 21 telescopes into the sleeve 22. The pages 23 are provided with the usual perforations which are of such a size as to readily pass over the sleeve 22.

It will be noted from Figs. 5 and 7 that the passageways 2O are unobstructed. In other words, neither the pin 21 nor sleeve 22 eX- tends into this passageway.

The assembling of the book is as follows:

The back clamps 11 are first placed in position on the back so as to form a pocket of suflicient width to receive the tongues 13'of thc holding members. The holding members are pulled out as indicated at the right side of Fig. 2. Then the page holders 16 and 17 are separated and the pages placed over the sleeve 22 after which the pin 21 is inserted in the sleeve 22 and the members pushed together until they bear against the inserted pages. The holder is then placed within the ycovers and the holding` members 14 pushed inwardly so that the'wings enter the passageways 20 thus preventing the members 16 and 17 from becoming separated.

From the foregoing it will be seen that no tools at all are necessary in order to secure the pages within the covers.

As more pages are added to the binder, that portion of the holding members 141 containing the'wings 15 is made wider and in order to compensate for this increase in width, the tongues 13 are made narrower. Then when a wider holding member is used, the back clamps 11 are moved backward on the back or hinge member 10 thus decreasing the size of the pocket 12 thus permitting the back or hinge to adjust itself in width corresponding as the book increases in thickness.k In other words as that portion of the holding member having the wings is increased in width, the tongue 13 is decreased so as to permit the back are located.

,lfn lligs. 8 and E) I have shown my cover in which a pocket is permanently termed by means of a row ot `titching :24 and in this pocketthe ends l-l Y holding members lll are inserted. lWhen the device is constructed in this n'ianner it will be un dcrstood that the pocket is not acljustable and consequently the tongues or ends 113 oi the members ll must all be of a uniform width regardless ot 'the width ot the end having the wings l5.

llilhilc I have shown my device with only two sleeves and pins, I do not desire to limit myself to this particular construction as I may use more pins depending entirely, of course, on the size ot' the page.

Having fully described my invention, what I 'claim is l. A loose leat ljiindcr comprising a pair ot covers, a `ilegible back tor hingedly connecting said covers and havin a pociicd formed in said back, a. plurality et pages removably located between said covers, and means including a member extending into the ends ot' said pocket for holding said pages within said covers.

2. A loose leart binder comprising a pair of covers, a flexible back for hingedly connecting said covers and having, an adjustable pocket Yl'ormed in said back, a plu ality of pages reinova bly located between said covers, an d means includ ing a member extending into said pocket for holding said pages within said covers. 4

3. A loose lea't binder comprising a pair ot covers, a. flexible back to r hingedly connectin said covers, means for 'termin a longitudinally ext-ending pocket .in said back` a' plurality of pages removably located between said covers, and means having a. portion eX- tcnding into said pocket for holding said pages within said covers.

il. A loose leat binder comprising a. pair ot covers, a flexible back :tor hingedly connecting said covers, means for forming an adjustable pocket in said back, a plurality ot pages removably located between said covers, and means including a member adapted to be inserted into said pocket for holding said pages within said covers.
