TEMPORARY BINDER OB LOOSE-SHEET HOLDER.

Specification of Letters Patent.

Application filed September 5, 1911.

Patented Feb. 13, 1912.

Serial No. 647,746.

To all whom it may concern Be it known that I, REINHOLD KRUMMING, a citizen of the United States, residing at the city of Milwaukee, county of Milwaukee, State of lVisconsin, have invented certain new and useful Improvements in Temporary Binders or Loose-Sheet Holders, of which the following is a specification.

This invention relates to improvements in temporary binders or loose sheet holders.

The main objects of this invention are: First, to provide in a temporary binder or loose sheet holder, an improved adjusting mechanism. Second, to provide an improved temporary binder or loose sheet holder of the post type which may be very easily and quickly adjusted to secure the leaves or to permit the removal thereof. Third, to provide an improved temporary hinder or loose sheet holder which is very simple and economical in structure and, at the same time, Very durable.

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

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawin forming a part of this specification, in which:

Figure I is a side view of a structure embodying the features of my invention, a quantity of sheets or leaves being shown therein. Fig. II is a. detail inside View with the sheets or leaves shown in Fig. I omitted. Fig. III is a detail transverse section showing details of the adjusting mechanism taken on a line corresponding to line 33 of Fig. I. the sheets being omitted. Fig. IV is a detail horizontal section through the adjusting mechanism, taken on a line corresponding to line 14 of Fig. III. Fig. V is a detail horizontal section through the adjusting mechanism taken on a line corresponding to the broken line 55 of Fig. III. Fig. VI is a vertical longitudinal section through one of the binding posts, taken on a line corresponding to line 66 of Fig. III. Fig. VII is a detail View corresponding to that of Fig. II, of a modified construction, the covers of the binder being omitted. Fig.

VIII is an'end view of the structure shown in Fig. VII.

In the drawing, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the structure illustrated is provided with a pair of covers 1 and 2. The binding members 3 and 4 are secured to the covers 1 and 2 respectively, by means of flexible hinge connections 5. The binding members 3 and 1 are provided with inwardly projecting overlapping back members or portions 6 and 7 respectively, which form the back of the binder. The binding members 3 and 4 are adjustably connected, the adjusting means in the structure illustrated in Figs. I to VI being adapted to serve as binding posts for the sheets or leaves 8 as'well as the adjusting means.

The adjusting mechanism of the structure shown in Figs. I to VI inclusive, consists of the tubular outer back members 9 which are mounted on one of the binding members at the ends thereof, and the tubular inner pawl members 10 which are mounted at the ends of the other binding member to telescope with the members 9. These members 9 are provided with longitudinal slots 11 extending from their outer ends. These slots are disposed on the outer sides of the members 9. Transverse kerfs 12 extending across the slots 11, provide a double series of teeth 13. The members 10 are provided with parallel longitudinal slits 14 which extend from the outer ends of the members forming spring pawls 15, the ends of the pawls being turned into tooth engaging portions or pallets 16. These pawls and their engaging portions or pallets 16 are of such width that the pawls engage the teeth at each side of the slot. The lower ends of the engaging or pallet portions of the pawls are beveled upwardly so that the pawls slipover the teeth on the inward movement. The finger pieces 17 are mounted on the pawls 15 so that they project through the slots 11 in the members 9 when the members 10 are telescoped therewith. The members 10 preferably have a close sliding fit in the members 9 so that the members are effectively guided and supported. The pawls when the parts are assembled, are protected and supported so that they are not likely to be injured by careless handling or manipulation. The adjusting members 9 and 10 are mounted on the binding members by means of the plates 18 having flanges 19 at their outer ends which are folded over the ends of the clamping member pieces 20 and 21, the clamping member pieces 20 being provided with tongues 22 which are arranged through slits 23 provided therefor in plates 18. (See Fig. III.) This provides a very secure attaching means for the members 9 and 10, and enables the very rapid assembling of the parts. Further, the posts can be readily detached should occasion require for purposes of renewal, repair or the like.

I preferably provide binding posts disposed interi'nediate of the adjusting members as shown in the drawing, although the adjusting members in the structure illustrated in Figs. I to VI are also adapted as leaf engaging or binding posts, the sheets or leaves being provided with notches 2 1 adapted to receive the same. (See Fig. IV).

The intermediate binding posts are of the well known type consisting of the outer members 25 mounted on one of the binding members, and inner members 26 mounted on the other binding member to telescope therewith. In practice, I preferably also use, the sleeves '27 adapted to telescope over the post 25. These are, however, not an essential and form no part of my present invention.

In the modification shown in Figs. VII and VIII, the adjusting member 28 is provided with a slot 29 and has a series of teeth 30 at each side of the slot. The pawl member 31 is in the form of a spring having an engaging portion or pallet 32 which coacts with both sets of teeth 30, and a finger piece 33 arranged in the slot 27. The pawl member is supported against lateral movement by this arrangement as in the preferred construction, but the preferred construction has certain features of advantage not possessed by this modified construction.

With the parts thus arranged the binder is adjusted to clamp the leaves merely by introducing the member 1.0 into the member 9 and pushing the same down to its clamping position. To release the binder, the finger pieces are pressed inwardly to disengage the pawls and the upper cover with its binding member lifted off. This can be conveniently done by grasping the ends of the binding member 3 between the first or index fingers and pressing upon the finger pieces 17 with the middle fingers. It is found that this is a very convenient way of releasing the binder and separating the binding members. Of course, different operators might prefer different methods.

I have illustrated and described my improved binder in detail in a simple and desirable embodiment. Other tmodifications other than shown, are possible, but I have not attempted to illustrate or describe the same herein as the structure disclosed will, it is believed, enable those skilled in the art to apply my invention as may be desired. I desire, however, to be understood as claiming my invention specifically in the form illustrated as well as broadly within the scope of the appended claims.
