Specification of Letters Patent.

Application filed Novtmber E11, 1907. Serial No. &0l,651.

hold, both in their open and in their closed position; second, to provide an improved temporary binder vor loose sheet holder, in which the sheets or leaves are held so that they are likely to get out of alinement in handling the binder, or in turning the leaves; and, at the same time, one in which the sheets or leaves may be very quickly insert'ed, or removed, or changed, as desired.

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

I accon'inlish the ob ects of m invention by the devices and means described in the following specification.

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

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which,

Figure 1 is a detail view of a structure embodying the features of my iuventit-m, the

covers being shown extended, and portions of the inner walls thereof being broken away to show the arrangement of the parts; sheets orlcaves being illustrated therein in conventional form; Fig. 2 is a longitudinal section, taken on a line corresponding to line 2 2 of Fig. 1, thc'sheets being shown in a vertical position, and the movement. of the covers being illustrated by dotted lines; Fig. 3 is an enlarged detail section, taken on a line corresponding to line 33 of Fig. 1; Fig. 4 isa plan of one of the sheets or leaves, which I preferably use in my improved binder; Fig. 5 is an enlarged detail taken on a line corresponding to line 5-5 of Fi 4, the figure being somewhat exaggerated to better illustrate the form ofthe leaf;

In the drawing, the sectional views are taken looking in the direction of the little arrows at the ends of the section lines, and

arranged pivot 5).

similar numerals of reference refer to similar parts throughout the several views.

Referring to the drawing, the covers 1 are p-ret'eably chambered to receive the binding cords and *e adjusting mechanism therefor. The cla. n ng bars 2 are pivotally connected to the inner ends of the covers, preferably by means of the inwardlyno jet-ting rigid hinge members at the inner ends of the covers and the pivot pins "l, by which the clamping bars are connected to the hinge member. The clamping bars are preferably slotted at 5 to receive the hinge members, and the pivots are inserted into the clamping bars, as clearly appears in 3. The covers are connected by the binding cords 6, which are arranged through the inner ends of the covers, and through the clamping bars, suitable holes 7 being provided therefor in the clam jiing bars. The binding cords are connected to one of the cover, preferably by means of the equalizing bar or cross piece 8, which is secured t the cover by means 01 a suitable centrallylhe cross bar 10 is adjustably connected to the other cover by means of the screw ll, which is wanted in suitable bearings, as 12, on the cover, the screw being adapted to be adjusted. by means of a key. This general arrangement of the covers, the clamping bars, binding cords, and adjusting means therefor is substantially that shown in Letters Patent- 851,276, issued to me on April 23, 1907, for temporary binders or loose sheet holders. The present structure is a modification, and, in some 1'' spects, an improvement upon the structure there illustrated.

The clan'iping bars are provided with bearings 13 in their inneror clamping faces for the binding cords. These bearings are so located relative to the pivots t for the hinge members to the clamping bars, that, when the covers are opened or closed, the binding cords are swung across the axes of the pivots, so that the tension on the binding cords is varied somewhat, it being the greatest, when the cover is partially opened. By thus araugingthe bimling cords in the clamping bars and the pivots for the clampingbars, the binding cords tend to hold the covers in either their closed or in their open position, and will either open or clo e the same when partially opened. This variation in tension is not sntl'leient to in any wise in jure the binding cords, or interfere with the manipulation of the book, but is found to be of advantage, especially where the books are to be used on racks, or the like; also, in holdin the 'covers in their closed position when t e books'are placed on a shelf in an upright position. By providing the equalizing bar 8 for securing the binding cords to one of the covers, great care is not required in adjusting the cords, and any uneven stretching of the two binding cords is compensated for.

I preferably employ, in my improved bindenleaves or sheets 14 having notches 15 in their rear edges, adapted to-receive the binding cords and having a thinned portion 16 lying in front of the notches, so that the clamping bars. engage both the thin portion and the thicker portion 17 of the leaf at the rear of the thin portion, thus engaging the leaves in a wedge-like manner, so that they areheld very securely, and it is quite imossible for them to get out of alinement in andling or using the book. This thinned portion preferably extends inwardly beyond the edge of the clamping bars, so that itforms a hinge or flexing point for the sheets, thus ermitting them to lie fiat when the book is opened. As the clamping bars and the covers are free to move independently of 4 each other in the opening or closing of the book, or in the manipulation of the leaves, and also in adjusting the clamping bars to the sheets or leaves, the leaves are very securely held, and the book mayibe very easily manipulated.

I have illustrated and'described my imrovements embodied in a binder such as is lllustrated in my patent hereinbeforc referred to, and I have particularly adapted the same to use in that relation. 1 am aware, however, that is applicable to and may be adapted for use in various other forms of binders.

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

1. The combination with the tovers, ot

--inwardly-projecting rigid hinge members at the inner ends of said covers; clamping bars pivoted, on said hinge members; and binding cords connected to said covers and arranged through the inner ends thereof and through said clamping bars, said clamping bars being provided on their clamping faces with bearings for said binding cords, the said bearings being below the plane of the axes of the clamping bar pivots, whereby the binding cords are moved across the axes of the said pivots in opening or closing the covers.

2. The combination with the covers, of inwardly-projecting, rigid hinge members at the inner ends of said covers; clamping bars pivoted on said hinge members; and binding cords connected to said covers and arranged through said clamping bars, said clamping bars being provided 'on their clamping faces with bearings for said binding cords, the said with bearings for said binding cords the said bearings being below the plane of the axes of the pivots for said clamping bars, Whereby the binding cords are moved across the axes of the said the covers.

4. The combination with'the covers, of clamping bars; pivotal connections for said clamping bars to said covers; and binding cords connected to said covers, said clamping bars being provided with bearings for said binding cords, arranged so that the binding cords are moved across the axes of the said pivots in opening or closing the covers.

5. The combination with the covers, of clamping bars; connections for said bars to said covers; binding cords uniting said covers, connected thereto independently of said clamping bars and bearings on said clamping bars for said binding cords, arranged so that the stress on said binding cords is increased and diminished again on the opening or closing of the covers.
