TRANSFER-BINDER.

Specification of Letters Patent.

Patented June 16, 1914.

Application filed December 30, 1912. Serial No. 739,186.

To all whom it may concern Be it known that I, SAMUEL M. Dows'r, a

' citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Transfer-Binders, of which the following is a full, clear, and exact description.

My invention relates to temporary binders and particularly those adapted to bind together one or more copies of a newspaper, periodical, magazine, or similar publication, in a compact and convenient manner so that the same may be readily handled by the reader.

The principal objects of my invention are to provide a binder the expansibility of which for binding purposes is practically limitless and which owing to its novel construction and arrangement of parts will not mutilate the publications bound therein; also to provide a back for the covers of such a binder that can expand correspondingly; to make it possible to withdraw any one or more of the bound publications without disturbing the other; and to accomplish these and other objects by simple and economical means, substantially as hereinafter fully described and as more particularly pointed out in the claims, reference being had to the accompanying drawings forming a part hereof, in which,

Figure 1 is a view of one of my improved binders showing the parts in perspective and separated one from another. Fig. 2 is a top plan view of my improved binder. Fig. 3 is an edge view thereof. Fig. 4 is an enlarged sectional view taken through one of the extension posts showing the samefin detail and provided With an extension member.

Referring to the drawings, A, A, represents the rectangular-shaped covers of my binder that are hinged along their rear or back edges by flexible portions B to clamping-plates C and C. The above named parts of my invention may be of any well-known or approved construction, and said clamping-plates C and C", usually consist of a comparatively narrow strip or bar of metal 0 that is covered or surrounded with leather or other suitable material. Clamping-plate C is provided at or near each end with a vertically disposed sectional post that projects at right angles therefrom and is tapped securely into a screw-threaded hole cut in said plate and is adapted to extend through opening 3 bored through the upper clamping-plate G in alinement with the same. These sectional posts are a well-known feature of loose-leaf binders, and consist of one or more cylindrical sections 4 that have screw-threaded tenons m extending centrally from one end, and a screw-threaded hole y in the other end. One of the sections of each of these posts is tapped into and rigidly secured to each end of clamping-plate C,.and the other sections. areadded thereto by simply screwing the tenon on the end of the one into the hole in the adjacent end of the other, until the posts are of suitable length to bind the publications between thecovers, and permit their unsecured ends to extend up through the openings 3, 3, of the upper clamping-plate O. The unsecured ends of these sectional posts, preferably, extend a slight distance above the upper surface of the clamping-plate G, where they are provided with suitable screw-heads-5 the shanks 4. of which are tapped into the screwthreaded holes in the upper ends of said posts.

Said heads are each provided with a skirted portion 5 that extends concentrically around the shank 4 and provides a channel or recess into which the upper end of the post extends and is seated when said head is screwed down securely thereon. The edges of skirts 5 are adapted to engage the margins of the openings in the clamping-plate 5 through which the sectional posts pass, when heads 5 are screwed into said sectional posts, and

permit a compression of the back of the binder corresponding to the length of said skirt so as to render the said binder more compact.

The magazines or periodicals are preferably held in place between the clampingplates by means of a flexible metallic tiestrip 6 which is of a length corresponding to the distance between the centers of the posts and is of comparatively narrow width throughout except that its ends 7 are enlarged and bifurcated, substantially as shown. One of these ties 6 is inserted between the leaves near the back of each magazine and they are then placed on the stiifened longitudinal edge of a back cover so that the bifurcations of the ends of the ties will embrace the sides of the posts 2. The clamping-plate of the top cover is then clamped down into osition, and thereupon the publications in the binder will be firmly held be tween the covers.

In order to confine and protect the back edges of the publications in my improved binder, I have provided a novel back for the binder which consists of a strip of flexible binding fabric 8, that-is, preferably, slightly less in length from its top to its bottom than the distance between the binding post 2, andone longitudinal edge 9 of this backmember is, preferably, stiifenedby inserting andsecuring a flat metallic stiffening-plate 10in. thehemmed edge thereof. The ends 11 of this stiffening-plate 10 extend beyond .the top and. bottom edges of the back-member andare adapted to engage the posts 2, in the vsame manner as the retaining tie-strip 6, above mentioned One of the surfaces of the back-member 8 is, preferably, provided with a plurality of scores 12 that extend parallel'to the reinforced edge and when said back is placed above the uppercover of the magazine it is folded or 1 creased along one of said scores, so as to conform to the thickness of the publications to be bound, while the remaining portion is inserted under or below the lowermost sheet of the material being bound. After this is done the clamping p late C of the top cover is placed in position on the posts and the whole binder'clam'ped together by means of the screw-heads.

It has often been found desirable to insert an index or fly-leaf inibinders of this type for one purpose or another, and this I prefer to do by securing a stiffeningcplate 14 to one edge of a ruled sheet of paper 15,

the ends of said plate having bifurcations 16 in its ends that are adapted to beengaged with the posts 2 before the binder is clamped together. .7 I lVhile I have shown and described my invention in connection with a two-post binder, and with certain arrangements and combinations of elements, it, of course, is obvious that numerous equivalent parts may be employed without materially departing from the spirit of my invention, and all such changes and modifications, I. desire it understood are to be included within the scope of my invention as embodied in the appended claims.

What I claim as new is: e.

1. A temporary binder comprising removable front and back covers the rear edges of which areadapted to clamp printed 'matterbetween them, bindlng posts there- 'for, a removable expansible flexible backadjacent printed matter,

with substantially concave recesses in its ends that engage said posts.

2. A temporary binder comprising removable front and back covers the rear edges of which are adapted to clamp printed matter between them, binding posts therefor, a removable expansible flexible backmember one edge of which is adapted to be clamped between the front clamping-plate and the adjacent printed matter, and the opposite .end of which is adapted to be clamped. between the back clamping-plate and the adjacent printed matter, and a removable tie-bar inserted in contact with the sheets of printed matter and extending be yond the upper and lower edges of said back-member and provided with substantially concave recesses in its ends that e11- gage said posts.

A temporary binder comprising. removable front and back covers the rear edges of which are adapted to clainp printed matter between them, binding posts therefor, a removable expansible flexible backmember one edge of which is adapted to, be clamped between the front clamping-plate and the adjacent printed matter, and the opposite end of which is adapted to be clamped between the back clamping-plate and the and a removable tie-bar inserted in contact with the sheets of printed matter and extending beyond the upper and lower edges of said back-member and mediate said posts and provided with substantially concave recesses in its ends that engage said posts.

5. A temporary binder for publications comprising covers, an upper and a lower clamping-plate, posts connecting said clamping plates, means that assist in securing said publications between said plates, and a removable flexible back one end of which is reinforced by a metallic strip having bifurcated endsthat interlock with said posts and is inserted between one of said clamping-plates and said publications and the free end of which is inserted between the opposite clamping plate and said publications.
