UNTED STTS sereni CARL E. DIETZ, OF IVIILVAUKEE, WISCONSIN',

Application filed April 4e,

To all whom t may concern.'

Be it known that l, CARL l). Dmrz, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful lmnrovements in Temporary Binders; and I do hereby declare that the following is a full, clear, and exact description thereof.

The invention binders.

The primary object of the invention is the provision of a temporary binder which may be manipulated with especial convenience for the removal of individual leaves or the insertion thereof.

The retainers may be readily threaded thru apertures in the leaves and thru grommets in the cover, and their resilient character readily facilitates their deformation7 so that the engagement of the retainers with the loops may be accomplished quickly. The pointed ends of the retainers contribute to the facile centering of the retainers in the holes. In securing position, they are reliable and adapted to withstand such force as they might ordinarily encounter without danger of detachment and separation of parts.

A feature is the ease of manufacture of the device which is composed of a minimum number of parts of simple construction,

lilith the above and other objects in view which will appear as the description proceeds, my invention resides in the novel con` struction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawing, I have illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode I have so far devised for the practical ap plication of the principles thereof, and in which:

Figure 1 is a plan of the device in unfolded position.

Figure 2 is a cross section on the line 2 2 thereof.

Figure 3 is a similar plan of the alternative modification, and

Figures e and 5 are cross sections on the relates 'to temporary TEMPORARY BINDER.

line &-- and w of Figure 3, respectively.

Back 10 is provided with a pair of supports 11 directed therethrough, and clamped by their inturned ends 12 on to thefbaclr. Retainers 13 are provided with eyes 14e pivoted on supports 11. rflee retainers are thin and flexible, and substantially semi-circular in shape. rllhey terminate in points 15 adapted to be threaded readily through openings in sheets of paper, and through grommets 16 on cover 17. By the exertion of slight pressure by the fingers, the ends 15 may be engaged under loops 18 directed through cover 10 and secured by a clinching portion 19. The cover 17 is capable of free movement on retainers 137 and the dotted lines in Figure 2 indicate its closed position. The retainers 13 may be readily removed from loops 18 and thus cover 17 may be released and leaves may be withdrawn or added. Thus the binder may be manipulated rapidly.

In the modification shown in Figures 3 to 5 inclusive, back 20 is provided at its edges with beads 21 and 22, enveloping wires 23 and 211, the beads being cut away as shown at 25, as is also back 20 at 26, to permit the free pivotal movement of retainer 27, the eye 28 of which is rotatable on wire 211. Retainer 27 is provided with a point 29 engageable under wire 23, the back 20 being cut away as at 30 to permit the insertion of end 29which may be inserted or withdrawn by the mere deflection of resili ent retainer 27.

The invention is not limited to a resilient retainer 27, but if desired, the retainer may be made rigid. and back 20 may be made resilient. The retainer is adapted to be threaded through openings 31 in leaves 32, and an inner binding strip 33 is secured to back 20 and to covers 34, the strip being cut away to permit free action of eye 26 and retainer 27., Outer binding strip 35 is also secured to back 20 and covers 34, so that they have hinged movement and are capable of moving into the position shown in dotted lines in Figure 4. The upper and lower edges of back 20 are bent inwardly providing reinforcing folds 36, giving the back transverse strength.

It is not essential that the retainer have an eye le. The retainer may be entirely de* tachable, a loop 18 being provided for each end. This construction would facilitate the assembly of the retainer with the back and v the cutout portion and held beneath said Wires, one end of eaoh of saidfretainers adapted to be detaohably held beneath the corresponding Wire.

2.' A, temporary binder for perforated leaves comprising a back portion having rolled Cylindrical edges out out at points along their length, a Wire Carried Within said cylindrical portions, and retainers hat@ ing their ends movably positioned Within 20 the cutout portion and held beneath said Wires, one end of each of said retainers and the adjacent portion of the corresponding Wire being adapted for a slight relative motion, whereby such end is detaohably held.

In testimony that l claim the foregoing I have hereunto set my hand at Milwaukee2 in the county of Milwaukee and State oi Wisconsin.

CARL P. DIETZ.
