LOOSE-LEAF BINDER.
No. 873,151. I
Specification of Letters Il'atent.
Patented Dec. 10, 1907.
Application filed une 27, 1907- Saris-1N0. 381-001.
To all whom it may concern:
Be it known that I, JOHN E. MiloLAcI-r- LAN, a citizen of the United States, residing in Boston, in the county of Sufiolk and State of Massachusetts, have invented new and useful Improvements in Loose-Leaf Binders, of which the following is a specification.
This invention relates to a certain novel construction and arrangement of parts whereby a loose-leaf-binder is produced in which a plate or bar provided with one-half of a set of leaf-receivin posts is rigidly secured to the cover, and-the other half of said set of leaf-receiving posts is rigidly secured to a plate or bar which is pivotally connected at one end with the stationary plate or bar and is adapted to swing therefrom and open the posts for the purpose of removing the leaves, and to be returned to and locked in position on and parallel with the stationary plate or bar, thus closing the opposite posts in the set for the purpose of retaining the leaves in the binder.
The nature of the invention is fully described in detail below, and illustrated in the accompanying drawings, in which Figure 1 represents a portion "of a looseleaf binder spread or laid open and embodying my inventionthe leaf-receiving posts being closed. Fig. '2 is a view in detail of the central portion of the cover with the posts swung open. Fig. 3 is a section taken on line 33, Fig. 1. Fig. 4 is a section taken on line 4-4, Fig. 1. Fig. 5 is a section taken on line 55 Fig. 2.
Similar letters of reference indicate corresponding parts.
a, a represent the two sides of a cover, and b is the connecting back thereof. Riveted or otherwise rigidly secured lengthwise to the back is the flat bar d. Pivotally secured at e to one end of the band is a swinging bar 9 similar in size and shape to the bar (1.
h, h represent two curved posts of substantially the shape of one half of a circle, notched at their outer ends, said posts bein rigidly secured to the bar d.
7c represent two oppositely curved posts rigidly secured to the bar g, and adapted when the posts are in a closed position, as shown in Figs. 1 and 4, to constitute (with the posts h) two complete closed posts for holding the leaves 8. The posts in themselves considered are not new in this invention.
The bar (I, which with its posts constitutes hand edge of said bar.
the stationary member of the device, is provided with raised lips of reverse L-shape Z, m and a formed up from the bar and with their horizontal portions facin the right A smal protuberance o is also formed up from the bar (1 near the end which is notpivotally connected with the bar g. The bar g, which with its posts constitutes the swinging member of the device, is provided at its inner edge with curved recesses p adapted when the device is closed to accommodate the posts h, and with three more recesses g, 1' and t in the same edge and of e ual depth which register respectively with t e lips Z, m and n. A curved slot u is formed near the hinged end of the bar g, and a pin '0 extends from the bar (Z into said slot.
When the device is closed, the swinging ary bar or member (1, the pin '0 is at the extreme right end of the slot 11., and the lips Z, m and n overlap the bar 9 by extending over and beyond the ends of the recesses q, r and t respectively. When the bars are in this pobar or member 9 is directly over the statlonsition they are locked by friction by means i of the protuberance 0 which presses against the underside of the bar g. When the dea vice is to be opened, the barg is easily swung from such closed position into the open position indicated in Fig. 2 by grasping the lip or handle to at the lower end of the bar g, and swinging said bar outward as far as the slot 41. will allow, resisting the frictional pressure of the protuberance 0. In this open position the leaves 8 are of course easily removed and others easily applied.
When the device is closed, the end of the lowest notch q abuts against the lip Z, allowing the advancin edge of the swinging bar to reach the fart er edge of the stationary bar, so that the bar 9 completely covers the bar (1. The lip m is longer and extends further toward the right edge of the bar (1 than the lip Z, and the highest lip 72. is longer still, whereby when the bar 9 is closing the lips n and m successively pass the advancing edge of said bar, (instead of the edge reaching both lips at the same time), and successively overlap the ends of the notches t and 1', thus reducing the possibility of the bar 9 becoming bent or buckling.
Havin thus fully described my invention, what I c aim, and desire to secure by Letters Patent, is
In a loose-leaf binder adapted to be applied to a cover having ordinary sides and a connecting back, a stationary bar or mem- -ber adapted to be rigidly secured to said nearest the pivotal connection of the bars being longer and extending nearer to the inner edge of the stationary bar than the lip which is at a greater distance from said pivotal connection, whereby said lips will successively overlap the swinging bar at the ends of the notches, for the purpose set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
