BINDER.

' Patented Oct. 22, 1907'.

Application tiled August 1l. 1906. Serial No. 330,232.

To all lwhom it may concern:

Be it known that I, FRED B. .I ORDAN, a citizen of the United States, residing at Winchester, in the county of Middlesex and State 'of Massachusetts, have invented new and useful Improvements in Binders, of which the following is a specification.

This invention relates to that class of binders ior holding loose leaves in which the leaves are impaled and held upon posts that are composed of members, separably connected so that they may be parted for the insertion or removal of leaves.

Heretofore such posts have usually been composed of members telescoping together; this is objectionable for the reason that such members have necessarily been made of different diameters, and it has therefore been difficult, if not impossible, to keep the edges of the sheets held thereby in true alinement; difficulty has also been experienced in passing the sheets over the post members of large diameter, while the post members of small diameter have not held the sheets with suiiicient security. i

A principal object of my invention is therefore to construct a binder-post composed of separable, slidably connected members which may be parted for the insertion or removal of loose sheets, and which shall be practically of equal diameter throughout; a further object of the invention being to so construct the posts that the walls of the engaging apertures in the sheets shall be engaged by said posts or post members at diametrically opposite points.

Still further objects of the invention are to simplify and improve the general construction and operation of loose leaf binders.

vVith these and other ends in View which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention; it being however, understood that no limitation is necessarily made to the precise structural details therein exhibited but that changes, alterations and modifications within the scope of the invention may be made when desired.

In the drawings: Figure 1 is a perspective View showing the back and the side members of a binder frame constructed in accordance with the principles of the invention. Fig. 2 is a plan view of the same showing the frame partly expanded. Fig. 3 is a plan view showing the frame contracted. Fig. 4 is a central longitudinal view of the frame. Fig. 5 is a transverse sectional view taken on the piane indicated by the the other side of the frame.

line 5-5 in Fig. 2. Fig. G is a transverse sectional view taken on the plane indicated by the line 6 6 in Fig. 2. Fig. 7 is a longitudinal sectional view taken on the plane indicated by the line 7-7 in Fig. -2. Fig. 8 is a longitudinal sectional view taken on the plane indicated by the line 8 8 in Fig. 2. Fig. 9 is a perspective detail view of one of the posts showing the post members separated. Fig. l0 is a perspective detail view showing the parts comprising one of the binder posts separated from each other.

Corresponding parts in all of the figures are denoted by like characters of reference.

The binder fra-me in its preferred form is composed of a back ,l and

side members

2, 3, said back and side members may be constructed of any suitable material;` castings of aluminium being preferred on account of the strength and lightness possessed by this material. The side members are provided with

side flanges

4, 4 and with

end flanges

5, 5 the end flanges of the two side members being overlapped and in sl idableengagement with each other so as to form a box like structure or frame. The back member 1 is provided with a centrally disposed upstanding boss G', said back memberl is also provided with pairs of lugs 7, 7 which are disposed longitudinally in alinement with each other. The lugs 7 serve to support longitudinally disposed pins or shafts 8 upon which slides 9 are mounted.

The

upstanding flanges

4, 4 of the

side members

2, 3 are longitudially apertured for the passage of rods 1l, 12 which are partly exposed through undercut portions or recesses l0, 10 in the inner side faces of the upstanding ianges, so that the said rods will be supported in unobstructing positions The rod 1l,which is connected with the side member 2 extends through one ofthe end flanges 5 and has a non-circular terminal portion 13 adapted to be engaged by a key whereby it may be rotated; said rod is provided with right and left-hand threaded portions 14 that are exposed through the undercut openings 10, and upon said threaded portions are mounted nuts l5 having laterally extendL ing wings 16; the rod 12 connected with the section 3 is smooth throughout, and the portions of said rod that are exposed through the undercut recesses 10 carry slides 17 having laterally extending wings 18, said slides and wings corresponding with the nuts and wings upon the threaded rod 11. A pair of levers 19 are pivoted upon a pin or fulcrum 20 upon the central boss 6; these levers are disposed across one another, and the ends of the levers are connected by links or toggles 21 with the slides 9 upon the longitudinal shafts 8, the pins or pivots 22 that connect the levers 19 with the toggles 21 are also connected with the wings 1G of the nuts l5 at one side of the wings 18 of the slides 17 at The wings 16 of the nuts l5 and the wings 18 of the slides 17 extend through and beyond the undercut portions or recesses 3--3 in the inner side faces of the iianges 4-4, and the levers 19 and the links or toggles 21 may thus be conveniently connected with the nuts 15 and the slides 17 which move in the said undercut recesses. By this construction the nuts, the slides, and the rods carrying the same are not only supported out of sight, but they are disposed in sucha manner that they will not interfere with oi obstruct the insertion of leaves into the frame. The levers and the toggles combine to form lazy-tongs that connect the

side members

2, 3 with each other and with the back member l.

It will be seen that under the construction described, by simply rotating the right and left-hand threaded rod 11 the nuts 15 will travel upon said rod thus operating the lazy-tongs to expand or to contract the trame according to the direction in which the nuts are moved, by moving the

side members

2, 3 apart from or toward each other as the case may be, the slides 17 moving freely upon the smooth rod 12.

The

upstanding flanges

4, 4 of the

side members

2, 3 have been illustrated as being provided at intervals with thickened or reinforced portions 23 which are provided with recesses or countersinks 24 for the accommodation of the heads 25 of the members of the binder posts. These posts P are composed of two separable slidably connected sections S, S, said sections being preferably of identical construction and dimensions in order that they may be used interchangeably. Primarily each post may be described as comprising a body which is preferably, although not necessarily, of cylindrical shape; the circular cross section being the most readily fitted to correspondingly shaped apertures in the loose sheets that are to be bound; the body oi each post is longitudinally` divided into two members or sections adapted for slidable engagement with each other, and each of these sections is composed of a plurality of longitudinally disposed members 26 connected together at one end, which may be described as the outer end, by the heads 25, while the inner or engaging ends of said members are free and disconnected. Ordinarily each section of the post will be composed oi but two longitudinal members as 26, but no limitation is made to this number; when the post, as is preferable, is of circular cross section, the individual members 26 will obviously be of sector shaped cross section, and where each post section comprises but two longitudinal members, said members will be diametrically opposed to each other so that each post section will be provided with diametrically opposite segmental curved bearing faces.

In the preferred construction of the posts, the heads 25 are provided with suitable sector shaped apertures 27 in which the outer extremities oi the members 26 are seated and secured in any suitable manner; the meeting or engaging edges of the members 26 of each post section are disposed practically in Contact with each other but they will readily separate sufficiently to enable the post sections to be assembled by sliding them together longitudinally as will be readily understood by reference to the drawings. The heads of the post sections may be secured in any suitable manner in the recesses or'countersinks 24 in the upstanding flanges of the side members of the binder frame; and said

upstanding side members

4, 4 are provided with apertures 28 or the reception of fastening members whereby the covers may be connected; said covers being readily detached from the flanges 4, when required, ior the purpose of rebinding or when for any reason it shall be desired to detach said covers.

It will be readily seen that when the post sections are connected with the side members oi the binder trame the posts will expand or contract with said side members, thus enabling the binder frame to be readily adjusted in such a manner as to securely clamp and closely engage the ever varying number oi leaves.

The improved construction of the binder posts is simple, strong, durable and effective, and it enables the binder to be expanded from its closed position to a position where its capacity will be practically twice the capacity of the binder, when closed. By the improved construction of the posts as herein described said posts will be practically of equal diameter throughout their lengths, and a very efhcient support will thus be afforded the loose sheets, the walls of the apertures oi which will be engaged by the post members at diametrically opposite sides.

Having thus described the invention what is claimed is:

1. In a loose leaf binder a frame having side members and a back member, rods supported in the side members, slides movable upon one of the rods, nuts engaging right and left-hand threads upon the other rod, lazy-tongs connected pivotally with the nuts and slides and includingl levers fulcrumed upon the back member' of the frame, and slides supported by said back member and having pivotal connection with the lazy-tongs.

2. In a loose leaf binder a frame including a back and side members, said side members having undercut por'- tions or recesses, rods supported in the side members and exposed through the undercut portions, slides engaging one of said rods, nuts engaging right and left-hand threaded portions upon the other rod, lazy-tongs connected pivotally with the nuts and slides and including levers fulcrumed upon the back member of the frame, slides supported upon and connected pivotally with the lazytongs, and rods supporting said slides.

3. In a loose'leaf binder a frame including a back and side members said back having a central boss and longitudinally disposed pairs of lugs, shafts or rods supported in said pairs of lugs longitudinally with relation to the back member', slides upon said shafts, rods supported longitudinally in the side members of the frame, one of said rods having right and left-hand threaded portions, slides and nuts engaging said rods and having wings extending through undercut portions of the side members, lazy-tongs connected pivotally with the wings of the nuts and slides and including levers fulcrumed upon the bosses of the back member, and pivots connecting the togglcs of the lazytongs with the slides upon the shafts connected with and supported by lugs u pon the back member'.-

In testimony whereof, I aiix my signature in presence of two witnesses.
