TEMPORARY BINDER;

Specification of Letters Patent.

Patented May 11, 1909.

Application filed July 25, 1906. Serial No. 327,603.

To all whom it may concern: 7

Be it known that I, OHAnLns R. NnLsoN, a citizen of the United States, residinglat Chicago, in the county'of Cook and State of Illinois, have invented certain new and useful Improvements in Temporary Binders, of which the following is a specification. 1

This invention relates to improvements in temporary binders, and refers more specifically to an improved temporary-binder designed as a transfer binder, t. e. a binder in which the disposed of contents ofv currentbooks may be filedza waypermanently.

Among the salient-objects of the invention are to provide a binder which constitutes a complete book-binding as distinguished from those which have heretofore been used for this purpose having open backs and at the same time to produce such a binder well within the limitsof reasonable cost; to provide such a transfer binder'having sectional impaling pins or posts yet so constructed that these pins or posts atno time protrude beyond the sides of the book so as to scratch or deface furniture; to provide a transfer binder which is variable asv to capacity over a Wide range, to provide an improved means of relia ly and conveniently locking'the side members in adjusted. relation upon the posts; to provide a trans-'- fer binder which is approximately uniform in appearance with the more elaborate and expensive books used currently, such as ledgers, day books, etc., and in general to provide an improved binder of the character referred to. e I

To the above endsthe invention consists in the matters hereinafter described and more particularly pointed out in the ap pended claims. p F 4 The invention w'll be understood from the following description, reference being had to the accompanyingdrawing, in whiche- Figure 1 is a perspective view of a preferred embodiment of the invention; Fig. 2

a is a view infront elevation of the binder 'IIGSS 3- 3 of Fig. 2, theleaves, however, being omitted Fig. 4c is a longitudinal sectional VlQW taken approximately on line 4:-4: of

Fig. 2 and lookingin the direction of the arrows; the leaves beingin this instance also omitted.

Referring to the drawing, 1 and 2, respectively, designate as a whole binder frame members which are desirably of cast metal,

such as aluminum, 3 and 3 designate the side covers which are hinged to the frame members 1 and 2, in any suitable manner, and 4 a detachable back which may be used with the binder or not as preferred. 1

The frame members 1 and 2 are desirably made of U-form 1n cross section, as best seen 111 Fig. 3, so as to secure at once rlgidity,

substantial thickness in the direction of the thickness of the binder, and relative light- Atthe points where the binding posts are seated, integral bridge blocks 5 are cast within the U-frames, and so also in the frame member 2 at a point intermediate its length a bridge block 6 is provided which is divided orrecessed, as indicated at 7, for a purpose hereinafter explained. Exteriorly the frame members are provided on their front sides with integral ears or lugs 8 which form hinge knuckles throughwhich the pintles of the side covers are extended. The end ones of these ears are in transverse register with the impaling posts 9 and are transversely apertured to receive the latter. In the member 1 the butt end sections of the posts are perma'nently seated, and to thisend the apertures 1,0are counterbored to receive the correspondingly shaped engaging ends of the posts which are riveted permanently in place. The apertures 9" of the member 2 are of uniform diameter throughout so that the posts may slide freely therethrough. Caps 11 are desirably provided to form finishing terminals for each post, and these caps are made of such diameter that'they also will pass through the apertures 9?.

In order' to lock the frame members in adjusted relation, a threaded actuating rod 12 is seated to extend lon,g 2;itudinally within the frame member'2; the two end bridge pieces 5 being suitably apertured to receive said actuating rod and the bridge member 6 being longitudinally grooved to admit the rod,'as seen clearly'in Fig. 4. A confining collar or annular rib 13upon the rod 12 fits within and engages the sides of the recess 7 hereinbefore referred to and confines the rod against endwise movement. The respective ends of the actuating rod are reversely screw threaded, and upon each threaded portion is mounted a traversing locking block, as 14 and 14. Rectangular ways are formed through the bridge members 5 to accommodate these locking blocks, as indicated at 15,

the front sides of these-ways being arranged to-intersect the proximate sides of the post apertures 9 so that the laterally outer ends of the locking blocks will impinge against and bite into the sides of the posts and thus lock the frame members in adjusted relation. In order to actuate the rod 12 one end thereof is squared to receive akey, as indicated at 16, and theend margin of the frame member provided with a registering keyhole 17.

Describing now the detachable back mem ber 4, this member desirably consists of a rigidcardboard or sheet metal plate or strip of a width. approximately equal to the binder when expanded to the desired capacity, shaped slightly convex as to its exterior, considered transversely, and desirably provided with end flanges 1 which overlap the ends of the leaves. From the body of the back at points'in transverse register with the respective binding posts, tabs 18 are struck out and turned inwardly to extend in a plane parallel with" the leaves and prefer ably about midwidtli of the back member. These tabs are of suitable length to reach to and engage the binding posts, and are provided with perforated and slotted apertures 19 so that they may be engaged with the posts by simply forcing them inwardly between the leaves. As seen clearly in Fig. f these tabs serve the purpose of holding the back in position. It being understood that the slotted portion of the tabs have spring clamping engagement with the posts after they are forced over the latter. In order to conceal the openings 20 formed in the back member by striking out the tabs, said back members are desirably provided with a covering of leather, cloth or other suitable binding material, as indicated at 21. It is to be understood that a variety of widths of these back members will be made or supplied so that when the binder has been filled a back corresponding in width to the thickness of the book may be selected and adjusted toposition, and thus become a permanent part of the file. 7 7

It will be seen from the foregoing description that I accomplish the several objects of the invention hereinbefore stated and produce a binderwhich is not only capable of being manufactured at anextremely moderate cost but forms a complete and perfect book binding for its contents. It is to be particularly noted that the depth of the socket openings 9 through which the impaling posts extend is such that the position of the binding member may be adjusted outwardly or inwardly over a range of adjustment nearly equal to the length of a post section without exposing the ends of the 0st beyond the ends of the sides of the inder frame. Accordingly it is never necessary to have the posts protrude so as to deface furniture or disfigure the binder; it beingunderstood that the capacity of the binder may be enlarged within any reasonable limits by simply adding post sections, in a manner well understood in this art.

I claim as my invention:
