OPEN-FACE SLIP INDEX.

Application filed March 7, 1919.

To all whom it may concern:

Be it known that 1, JOHN PEASE NORTON, a citizen of the United States, residing at e60 Ocean Ave, WVest Haven, Conn, in the town of Orange, in the county of New Haven and State of Connecticut, have invented new and useful Improvements in Open-F ace Slip Indexes, patented by me Dec. 15, 1914, Patent Number 1,120,967, of which the following is a specification, reference being had to the accompanying drawing forming a part hereof.

My invention relates to improvements in my open-face slip index; and the objects of my improvement are, first, to provide a holder for a considerable number of slip index panels of the particular type described below which enables any leaf to be removed or inserted without disturbing adjacent leaves vby'handling; second,- to render accessible for instant reference a considerable number of leaves without touching directly other leaves than the one desired; and, third, to provide protection for the slip index panels both from unnecessary handling when in use and from dirt and dust when not in use if so desired.

Other embodiments of the fundamental elements of the invention will be described subsequently.

In the drawing which accompanies this specification, Figure l is a front view of the cabinet in which the removable tray is mounted and rotated so that the leaves are without the cabinet. Figure 2 is a fragmentary view showing the cabinet with the top cut away and the tray rotated so as to display the leaves within the cabinet. Figure 3 is a cross section view of a cabinet case with trackways forming abbreviated stub recesses and showing a possible embodiment of the invention without the provision of a free space above the stub for the purpose of vertically removing a single leaf without disturbing adjacent leaves. Figure 3 is a cross sectional view of a tray removed from such a cabinet as is illustrated in Figure l with one leaf in position showing the elements of the invention present in the combination of stub, panel, cord hinges and stub recess of tray. Figure 4: discloses a view of asingle leaf comprising a stub and a panel, the two attached by a cord hinge; Figure 4 discloses a view of a single panel with stub Serial No. 281,296.

attached by a cord hinge as subsequently explained.

The invention will be more clearly understood by referring to the accompanying drawings in which the same element is designated by the same letter throughout the drawing. The typical slip index panel is designated by E. Inasmuch as the various slip index panels with trackways carrying the cushion slips may be more conveniently handled when bound together in some loose flexible way which permits the turning of the panels as leaves are turned in a book and at the same time permits insertion and removal of leaves the invention now dis closed is adapted to accomplish these purposes. Obviously, it is impossible to bind up the panels in book form using ordinary book binding methods on account of the thickness and rigid nature of the panels, and, it, therefore, becomes necessary to devise a new type of hinge adaptedto leaves of considerable thickness.

The applicantis aware that this difficulty has been surmounted in various ways in the case of heavy leaves by the use of heavy cloth hinges and by metallic attachments acting either as hinges or as axes of rotation, variously arranged. But both the ordinary heavy cloth hinge and the metallic attachments which provide for a swinging motion in heavy stiff leaves fail to provide the flexible results accomplished by the novel cord hinges, herewith disclosed.

The slip index panels E are, then, pro vided with stubs J, connected together by cord hinges T. The method of joining the stub to the panel preferred by the applicant is illustrated in Figure 8. A series of holes R are punched in the stub J commencing at the upper and lower ends N and Q, of the stub J at an equal distance from the stub ends roughly equivalentto one half the distance between the regularly placed holes. A corresponding series of holes S are placed in the edge of the panel E commencing at a point distant from the upper and lower edges of the panel roughly equivalent to the distance between the regularly placed punch holesv This arrangement makes the holes R of the stub positioned diagonally to the hole S of the panel.

A strong flexible cord or narrow tape is then threaded through the holes, preferably,

description of Figure 3*, since the two independent stub recesses could not be conveniently removed together with the leaves from the cabinet without separating and disarranging the leaves, as it is possible to do in the arrangement shown in. Figure 3: It will be noticed in Figure 3 that the upper projection (i is somewhat longer than the lower projection H. The position of the stub J in the tray B is shown clearly in Figure 3. The lower end Q of the stub J rests on and is'supported by the side P of the tray B. The stub J is prevented from tilting forwards or backwards by the lips H and G which enter the opening M between stub J and panel E, the same being joined by cord T laced through punch holes R and S as previously described. Withdrawal of the lock rod V permits the upper end N of stub J to be lifted sufiiciently for lower end Q of stub to clear lower lip H whereupon the leaf may be withdrawn by a forward downward motion without disturbing other leaves. The space U permits stubs to be removed and inserted in the manner disclosed. The same result can be obtained by omitting the upper side of the tray K and shortening G, supporting G from the sides of the tray frame. But in any such arrangement, G is less desirably supported. l shows the cushionslips mounted in leaf E. A leaf is placed in position by first inser ing end N of stub J in the tray until N comes against K whereupon Q end of stub J is dropped into tray and brought up against tray wall P; In order to open the leaves to a greater extent, dummy stubs carrying no leaves may be inserted between the stubs carrying leaves for the purpose of spacing. This method of holding the stubs permits all leaves to lap somewhat so that it is possible to index the leaves in accordance with the information contained" and immediately to select the leaf desired without turning over other leaves by hand ling directly as would be the case-(if the leaves were bound in book form.

In all arrangements of the trays, whether flat, convex or concave, an additional'leaf can be inserted. between any two leaves up to the capacity of the trays and so growth is provided for both in leaves and in lines which are freely insertable and removable In other systems, known. to the applicant. the insertion of a new leaf involves considerable adjusting. Thus in metal attachments which swing as axes of rotation, the ends resting in holes in a standard. to in sert a new leaf requires all leaves to be lift ed out and moved forward. 7
