LOOSE-LEAF BINDER.

To all whom it may concern.'

Be it known that I, HENRY IInLLwnG, of Milwaukee, Wisconsin, have invented a Loose-Leaf Binder, of which the following is a specification.

This invention relates to loose-leaf binders, and has for its object to provide a siniple, cheap and effective means for clamping one of the back-bars of a binder in any desired position.

The invention has special application to those forms of binders having sectional posts, and when so used, has for a further obj ect to provide a form of back-bar, which avoids the necessity of having the ends of the post project beyond the bar.

According to my invention, I provide upon the face of an ordinary back-bar sliding upon the post of the binder, a clampingmember in the form of al bar, having an aperture at one end passing over one of said posts, and an internally threaded aperture at the other end passing over the other post, together' with a manipulating-member having an aperture fitting over said secondpost and turning thereon, as on a pivot, and an external screw-thread eccentric with the aperture and engaging the screw-thread on said first-named member; the effect of turning said manipulating-member being to force the two posts apart through a distance slight but sufficient to cause them to engage frictionally the edges of the apertures in the back-bar through which they pass.

In a more elaborate form of the device for sectional-posts, I may provide a boxshaped back-bar adapted to hold and contain the projecting ends of the post, whereby the latter are prevented from projecting in an inconvenient and unsightly manner, as is customary according to present constructions.

To enable my invention to be fully understood, I have illustrated the same in the accompanying drawings, wherein- Figure 1 is a side-view of the met-al-port-ions of a binder-back constructed in accordance with my invention, any cloth or paper filling or covering being omitted; Fig. 2 is a fragmentary longitudinal section through the upper portion of the same, taken in the plane of the post-axes, and fragments of the posts being shown in elevation; Fig. 3 is a plan-view of the same; Fig.

4 is a plane-section taken in the plane of the upper surface of the clamping-bar; Figs.

Serial No. 627,155.

5, 6 and 7 show an alternative form of the invention, Fig. 5 being a vertical transverse section taken on the plane 5, Fig. 6 a longitudinal section in the plane G, and Fig. 7 a fragmentary plan-view 'of the right-hand end; and Fig. 8 is a perspective view of the eccentric-member shown in Figs. 1 to 4.

The reference letters refer each to the same part in each figure of the drawings.

In the simpler form shown in Figs. l to 4l, the two back-plates are designated by the letters A. and I3, and the two posts C being mounted upon the lower plate A and sliding through apertures 2) in the plate B. Upon the latter lies the clamping-bar D, which is loose upon the back-plate and may be held in position by the head of a screw E mounted as shown upon the plate, and the aperture d in the bar D through which the screw E passes being made somewhat larger than the shank of said screw as shown, so as to permit a slight movement of the clamping-bar. At one end, the lefthand end in the drawing, the bar D has an aperture (Z2 through which the left-hand post C passes, and at the other end it has a threaded aperture d in which engages the thread f of an eccentric-piece F, said eccentric-piece being perforated with a central aperture f2, through which the other post C passes; the eccentric-piece being thus, in effect, journaled upon said post. A manipulating-handle f is conveniently provided upon t-he piece F for throwing it into clamping and releasing positions.

Now it will be observed that the screwthread f is slightly eccentric with respect to the central aperture f2 as shown clearly, and also somewhat exaggerated in Fig. 8; whereby the angular movement of the eccentric-piece varies the distance between the two holes (Z2 and f2, and thereby throws them into or out of register with the two holes In only one angular position of the eccentric-piece F do the holes (Z2 and f2 register with the holes b', so as torelease the posts; in shifting the eccentric-piece, as indicated by the dotted and full-line positions in Fig. 3, the holes Z2 and f2 are moved closer together or farther apart, thereby jamming the two posts C between the holes o', d and f2 as clearly indicated by the' open spaces in Fig. 2, in which the clamped position of the post is shown. The eccentricpiece F cannot of course be rotated through an entire revolution so long as the' clampingplate remains upon the post, and therefore the eccentric-piece cannot. become accidentally detached; but it is unscrewed by removing the clamping-plate from the post.

The other form of device shown in Figs. 5, 6 and 7 is especially adapted to sectional posts. The two posts C are supposed to be composed of short-sections c united end to end by any of the well-known means or devices common to the art. In place of the sliding back-plate B, I use a backeplate B which is in the form of a closed box of rectangular section as shown; this box is deep enough so that the ends of the sect-ions c at no time project therefrom. As before, the back-plate B is provided with apertures through which the posts pass, said apertures being in this case double, and the lower ones being designated b2 and the upper ones b3. A clampingbar D is used which is in all respects similar to the clamping-bar D, except that the aperture d and the screw E are omitted in this case; said clamping-bar is held in position by a pair of spacing-sleeves G. The eccentric-piece F is in this case in tubular form having a central aperture f4 through which the post passes and an eccentric-thread f5 on its lower end engaging the internal thread on the bar D', and instead of the handle f3 the eccentric-piece has a flange f on the upper face of the bar B, said fiange being perforated with apertures f7, whereby it may be turned by the application of the pin-wrench H; this is merely one of many similar means of rotating the piece F.

It will be apparent that should the top of the end-sections c project beyond the upper face of the plate B, said sections can be unscrewed and removed as is necessary, because in this case the clamping will be performed against the next lower section, so that the objectionable projecting ends of the posts are avoided.

I wish it understood that my invention is not limited to the use of all the above described features and constructions, for some may be omitted and others may be varied or modified in various ways, as will readily occur to those skilled in the art.

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

member mounted upon said sliding-bar and having an aperture at one end through which one of said posts passes andy an internally screw-threaded aperture at the other end through which the other post passes, and a manipulating-member having an aperture through which the second post passes and an external screwsthread engaging said internal thread and cutupon said manipulatingmember eccentric to the aperture therein, whereby the rotational movement of said manipulating-member causes a longitudinal relative movement of the respective apertures in the two members.
