HARRY F. BUSHONG, OF PORTLAND, OREGON, ASSIGNOR, BY MESNE ASSIGNMENTS, TO

' KALAMAZOO LOOSELEAF BINDER COMPANY, A CORPORATION.

LOOSE-LEAF LEDGER.

To all wkomt't may concern:

Be it known that I, HARRY F. BUSHONG, a citizen of the United States, and a; resident of Portland, county of Multnomah, and State of Oregon, have invented a new and useful Improvement in Loose-Sheet Binders,

of which the following is a specification.

The main object of this invention is to provide an improved temporary binder, by which the leaves or sheets are securely clamped at their inner or binding edges, and at the same time eitheror both covers or the leaves may be opened with the same facility as an ordinary bound book.

Further objects, and objects relating to structural details, will definitely appear from the detailed del 5 scription to follow.

the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which, I V

Figure 1 is a detail inside plan of a structure embodying the features of my invention, the covers being shown in their extended or open position. 2 is a detail'longitudinal section taken on a line corresponding toline X- X of Fig. l, the binding cords and theiback being omitted- Fig. 3 is a partial perspective of a detail of the construction shown in Fig. 1.

In the drawing, similar letters of reference refer to similar parts throughout the several views.

Referring to thedrawing, the covers .a a are prefers ably provided with side strips b and c, which project inwardly at the inner ends of the covers to form hinge members 11 and c. The clamping jaws d and e are pivotally supported on these hinge inembers by the pivots t. The adjacent faces, or the clamping portions of the clamping jaws are made more or less fiat, as at 40 e and their upper portions, as e are made rounding so as to facilitate the bending of the leaves in either direction in opening the book.

The covers are united by means of the binding cords h and h. The binding cords are secured to the cover sections a, such cover section being provided with cavities i in which are arranged clamp-like plates'j under which the ends of the binding cords project. The binding cords are preferably made of leather with nuts threaded thereon for securing them.

I Specification of Letters Patent.

Application filed July 15, 1904. Serial No. 216,663.

The cover a is provided with a chamber or cavity Patented Sept. 24, 1907.

bar is adjusted by means of the threaded shaft 0, the shaft being provided with a square key end 0 The right end of the threaded shaft or rod 0' is held in place by a guide plate p, and the left end is arranged in the socket bearing q. The outer end of the section a is provided with a suitable cavity, suitable to allow a key to be placed on, the end 0 of the rod by means of which it is manipulated to adjust the binding cords. The cover a is also provided with longitudinal grooves Z Z, extending from the chamber m to the inner edge of the cover, these grooves being adapted to receive the binding cords, as is illustrated. At the inner edge of the covers a are guide plates is for the binding cords.- The binding cords are arranged through clamping bars or jaws, each clamping jaw being provided with holes r. and cavities s therefor. These cavities are of such size as to allow the clamping bars to rock .independently of the binding cords. r

A sufiicient space, as f, is left between the back of the clamping jaws and the inner edge of the main part of the cover so as to allow an independent movement of the clamping jaws and covers. By this arrangement, the sheets are securely clamped and at the same time the book may be readily opened at any place and the sheets lie fiat or comparatively so.

When it is desired to insert or remove any of the leaves, it is only n'ecessaryto release the binding cords by means of the screw 0 when the leaves may befreely removed, or new ones inserted. It is evident that,

after the leaves are adjusted, the binding cords can be V tion may be mentioned: The means provided by me for binding the leaves between the outer covers do not take up any room at the back of the book, norcause there any hub or ridge lifting the outer covers to any considerable incline, instead of allowing the same to lie substantially flat when the book is opened. The clamping jaws e,- d, automatically adjust themselves to every possible position and arrangement of the covers and. the leaves. bodies, the clamping jaws and the binding cords, incidental to the opening and closing of my book, the integral portions u, of the upper wall'portions of the jaws d, e, hold the binding cords in place. My. binding means are further adapted to allow the covers to'be adjusted to any number of theleaves, that is to say, there is no maximum or minimum limitation of the leaves which may be inserted between the covers of my book; but a single sheet may be inserted to begin with, and any desired number of sheets added from time to time,

My binding means are further adapted to allow the' During the motions of the cover leaves of the book to be arranged substantially flat at whatever place the book maybe opened and whatever the number-of sheets bound between thecovers.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In a temporary hinder, the combination of the covers having inwardly projecting hinge members at their inner ends; clamping jaws pivoted to said hinge members in such position that the covers and said clamping jaws may move independently on the pivots while opening and closing the book, the upper portions of the said jaws being made rounding binding cords uniting said cover sections; means for adjusting said binding cords; the body of the covers being made with suitable cavities to contain the binding cords and the mechanism for adjusting the same, the clamping jaws also being provided with suitable cavities to receive said binding cords.

2. In' a temporary binder, the combination of the coveris having inwardly projecting hinge members at their inner ends; clamping jaws pivoted to said hinge members in such position that the covers and said clamping jaws clamping jaws pivoted to said'hinge members in such po sition that the body of the covers and the'clamping jaws may move independently on the pivots while opening and closing the book, the upper inner, portions of said jaws being made rounding; binding cords secured to one of said covers; and means for adjusting-said binding cords carried by the other cover, said jaws being provided with cavities s therein and holes r therethrough opening into said cavities through which said binding cords are arranged.

4. In a temporary binder, the combination with the cov- V ers having inwardly projecting hinge members thereon, of

clamping jaws pivoted to said hinge members in such position that the body of the covers and the clamping jaws may move independently on thepivots while opening and 010s ing the book; binding cords secured to one of said covers;

and means for adjusting said binding cords carried by the other cover, said jaws being provided with cavities s therein and holes 1* therethrough opening into said cavities through which said binding cords are arranged.
