To all whom it may concern:
Be it known that I, James H. Reno, J r., a citizen of the United States, and resident of North Tonawanda, in the county of Niagara. and State of New York, have invented new and useful Improvements in Leaf Structures for Index Devices, of which the following is a specification.
This invention relates to a novel leaf structure for index or display devices of the kind known as visible indexes, wherein a series of stiif leaves for carrying indexed data or other matter are hinged to a support. Such devices are used mainly for d18- playing a set of index cards or strips, and although capable of use for other purposes, such as displa g samples, advertising matter, etc., a eaf structure adapted for index cards or strips will be shown for the se of illustration.
drawings in which In the accompanying the invention are certain embodiments of exemplified,-
Figure 1 is an elevation of a leaf structure containing the invention;
Fig. 2 is an enlarged section on line 2-2 of Fig. 1;
Fig. 2 is a similar sectional view showing a modification;
Fig. 3 is an enlarged section on line 3-3 of Fig. 1;
Fig. 4 is a similar; sectional view showing Fig. 5 is an enlarged section on line 55 of Fig. 1.
The leaf structure comprises an outer frame A, consisting of a single. continuous rod of metal, bent into the form of a U to embrace three sides, namely, the top. bottom and outer margins of a rectangular leaf. Said single piece outer frame also has at its free ends a pair of hinge members 0., a, preferably in the form of books or pivot pins, made integral with the frame. to engage sockets in the support or standard (not shown) to which the leaf is hinged.
One or more panels B. are supported by the outer frame and extend between the legs of the U. Each panel B may be of sheet metal. and may be permanently or detachablv mounted in the outer frame. Each panel is also preferably double faced so as to receive indexed matter on both sides. For this purpose two marginal guide channels are provided at each vertical edge of the panel, one on each side, for holding index cards or strips. In the preferred form said channels areformed by a single piece C of sheet metal, bent U-sha ed in cross section, and extending-aroun the edge of the panel badly, each flange of the air of flanges c t us formed being folded mto the channel as shown at c, furnishing a smooth and finished edge. In the form shown in Fig. 2 the channel strip C is made in a separate piece from the panel, and is secured thereto by means of one bent margin 0' which engages and embraces the inwardly bent flange b on the edge of the panel. In the form shown in Fig. 2 the double channel C is integral with the panel, and is bent into substantially the same 'U-shaped form as in Fig. 2, with the margins of the flanges c foldedinto the channels. One of the folds o, however, is a continuous and integral part of the material of the panel, instead of being separate and secured to a flange of the panel as in Fig. 2.
The flanges o of each opposed pair are extended beyond the edge of the panel body, and form pairs of fingers (l, which project beyond the top and bottom edges of the panel. These fingers embrace the outer frame A. at top and bottom, and support the panel in the frame. To have the panel removable from the frame, the fingers d may be left to engage the legs of the frame loosely without other securement. The top edge 71' of the panel body (Figs. 1 and 3) will then preferably be spaced from the top leg of frame A sufliciently to allow the panel to be raised in the frame until the fingers d at the bottom are clear o the bottom leg of the frame. whereupon the fingers d at the top may be withdrawn. Or, without the clearance afforded by reducing the length of the panel to the line b, the panels could be detached by springing the top and bottom legs of the frame A apart until the fingers d are released.
When the panels are to be permanently mounted in the frame, the fingers d will preferably be shown at d, F'g. 4. and will also be welded or soldered to the frame.
In leaf structures heretofore used, so far as I am aware, there has been no marginal frame at the vertical free edge of the leaf other than the guide flanges themselves; and index tabs secured directly to the guide flanges of the panels. when used as handles to manipulate the leaves, tend to distort the clinched over the frame, as
panels and their flanges. With my improved leaf structure an index tab E may be secured directly to the outer frame A, by
which it is supported wholly independently of the panel and its flanges, whereby the frame and not the panel or its flanges W111 receive the strains due to handling the tab. The tab E is formed of a single piece of sheet metal folded over ugaon itsl If to form a two 1y body portion or displaying the index ettcr or other character, while the free ends of the folded iece are bent first outward and then inward, as best shown in Fig. 5, to form it pair of bowed arms e, e, which embrace the outer frame A and en port the tab on the frame A independent y of the anel. Said arms e may be soldered or wel ed to the frame, or they may be merel sprung around the frame member and amped thereon by reason of the resilience of the material of the tab, thus supportin the tab frictionally on the frame, and a mitting of vertical adjustment of the tab on the leaf.
I claim:-
1- .A leaf structure for hinged-leaf index devices comprising a sheet panel provided along the outer free edge of the leaf with a flange forming a channel for retaining index members on the panel, and a bar extending along said outer edge and opposite ends of the panel and forming a strengthening frame which the one isthseclllired, said avmg' parts a jacent e i edge of the leaf ada ti the frame to 13m:- alliylr supported or inging the leaf, and an in 'cator tab which is attached directly to said frame bar at the outer edge of the leaf and is free from said panel, whereby said frame receives the strain incident to the manipulation of the leaf by .thetab and the manilpulation of the tab W111 not distort the pane or said channel H 2. A leaf structure of the character de- 45 scribed comprising an outer frame, and a.
panel having a pair of inwardly .fac' guide flanges at each side of the anehs id guide flanges extending beyond t e edge of the panel body and forming'fingers to en-. gage the outer frame.
3. A leaf structure of the character described comprising an outer frame, and a panel having a pair of inwardly faci nude flanges at each side of the anel, sai guide flan is extending beyond the edge of the panel ody and forming rs to engage the outer frame, said pane being removable from the frame by withdrawing saldtfingers and said frame from engagemen 4. A leaf structure of the character described com ri an outer frame, and a panel locate within said frame and hit pro ecting garte s/t opposite edges which straddlesai outer frame for retaining the panel in place therein, said panel terminating short of said outer frame at one edge and said rojecti arts at one o of he panel Hg P dge ing longer than those at the opposite e of the panel to enable the removal of t panel.
5 A leaf structure of the character described, comprising an outer frame consistmg of a piece of metal bent into U-shape to embrace three sides of the leaf, and a filanel locgtllald between of said outer me an avlng pro ectlng arts at site edgeswhich embrace said enter 3%: for retaining the panel in place therein, said panel termina short of said outer frame at one e an said projecting parts at one edge of t 0 panel be longer than those at the opposite edge 0 the panel to enable the removal of the anal.
