MAGAZINE FOR LOO-SE LEAVES.

Specification of Letters Patent.

Patented Jan. 21, 1919.

Application filed December 26, 1914. Serial No. 879,015.

To all whom it may concern:

Be it known that I, WELLINGTON H. KID- DER, a citizen of the United States, residing in Roosevelt, Long Island, in the county of Nassau and State ofNew York, have invented certain new and useful Improvements in Magazines for Loose Leaves, of which the following is a specification.

This invention relates to means to facilitate the handling of a quantity of loose leaves, which may be supported in a pile on a stand or work-table, when it is desired, for example, to make entries on different sheets or leaves without permitting them to become disarranged, or to get out of a certain order.

The invention is particularly adapted for use in connection with a work-supporting table or leaf used as an adjunct to a stand or support for a typewriting machine, particularly one which is combined with a computing mechanism. A pile of loose sheets may be placed on the work-table when it is desired .to make typewritten entrieson certain selected sheets or on all the sheets seriatz'm, which are removed one at a time from the pile to receive the entries, each sheet after the entries have been made thereonbeing restored to the work-table prior to the removal of the succeeding sheet.

The present invention provides means for holding the sheets in their proper order and position on the work-table, preventing them from being misplaced when returned to the work-table and facilitating the selection and removal of individual sheets.

In carrying out the invention, there may be mounted on the work-table, impaling pins projecting upwardly above the surface of the table, to engage marginal perforations in the work-sheets. These impaling pins may be curved and arranged with their upper ends adapted to be brought together, so that each pair forms a ring or loop.

Suitable mechanism is provided beneath the top surface of the work-table, for opening and closing the rings. The work-table may be formed with a longitudinal recess or trough, to accommodate said mechanism. The latter may comprise a pivot rod extending longitudinally of the trough, on which rod the impaling pins are mounted, said pins having arms within said .trough and operatively connected as by means of cam slots and pins, with a rock shaft also extending longitudinally within said trough. B y rocking the shaft in one direction, the rings are opened, permitting the work-sheets to be placed thereon or removed.

The pile of work-sheets may be placed on the pins, so as to extend at one side of the pins. The sheets may then be individually removed to have typewritten entries made thereon, each sheet being placed on the opposite pins after the entries have been made. Said rock shaft may be actuated to close the said rings, so that the sheets may be turned over as the leaves of a book from one side to the other-without becoming disengaged from the pins, thereby enabling any selected sheet to be brought to the top of the pile for removal.

An operating handle may be positioned adjacent the typewriter stand and operatively connected to the said rock shaft, the handle thus being in convenient position for manipulation by an operator seated at the stand.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a front elevation view of a supporting stand for a typewriting machine or a computing machine, with the invention applied to a work-table or leaf of the stand.

Fig. 2 is a plan view of the work-table with the loose-leaf holder mounted thereon.

Fig. 3 is a part sectional front elevation view on a larger scale, showing the looseleaf holder in closed position.

Fig. 4 is a similar view, showing the said holder in open position.

Fig. 5 is a sectional elevation View taken longitudinally of the leaf-holding mechanism.

Fig. 6 is a detail perspective view, showing a holding ring in closed position.

A stand on which a writing machine, adding machine, or combined writing and computing machine 1 may be mounted, comprises tip-rights or legs 2, a top. 3 and cross braces 4. Work-tables 5 and 6 at opposite sides of the stand are shown as hinged leaves removably attached to the stand by means of brackets 7 formed with open ends or hooks to engage rods 8, said leaves being supported at their outer edges by diagonal brace rods 9, the lower ends of which enter sockets 10 on the frame of the stand.

The means for holding the loose leaves or workpieces in position on the work-table comprises pairs of holding pins 11 forming rings or loops which may be arranged in a row extending forwardly and rearwardly across the work-table 5. These holding pins are supported and actuated by mechanism located beneath the surface of the table, allowing the work-sheets or leaves 12 to lie fiat 011 the table. 7

The table 5 has a portion cut away to form a longitudinal trough or compartment 13 to receive a pivot rod 141 on which the pins 11 are mounted, and a rock shaft 15, also beneath the table, has suitable means for swinging the pairs of pins 11 to opened and closed positions. The connections between the shaft 15 and the holding pins 11 comprise pins or rods 16, which in eeffct are cams, fixed to the shaft 15 and extending through cam slots 17 in arms 18, which arms may form integral extensions of the pins 11.

When the shaft 15 is in the Fig. 3 position the rods 16 hold the impaling pins 11 in closed position with their outer ends abutting to form a closed loop or ring on which the leaves 12 may be guided and turned over like the leaves of a book, to project in either direction from the ring. The leaves 12 may be provided with perforations to receive the pins 11. These may be the usual perforaions commonly provided in ledger leaves and the like for use with loose leaf binders. By rotating the shaft 15 from the Fig. 3 position to the Fig. 4: position, the pins 16 are carried along the cam slots 17 and thereby swing the arms 18 apart, separating the impaling pins 11 as shown in Fig. 4.

The rock shaft 15 has portions cut away opposite each pair of impaling pins to accommodate the arms 18. In other words, the shaft 15 comprises cylindrical sections united by integral webs 19 opposite the arms 18. As shown in Fig. 4, these webs 19 may form positive means to hold the impaling pins in open position, the surfaces of the webs playing the part of cams. The shaft 15 may be rocked by means of an operating handle 20 on a lever fulcrumed at 21 and connected through a link 22 to an arm 23 fixed to the forward end of the rock shaft 15. The movement of the handle 20 is limited by stops 2%. The handle 20 is located within convenient reach of the operator.

The compartment 13 may be provided with lateral recesses or slots 25 to accommodate the portions of the pins 11 beneath the surface of the table 5. The opening 13 in the table is covered by a plate 26, which may be set into the table so that its upper face is flush. with the surface of the table, and said plate is formed with slots 27 through which the pins 11 project.

In use, a pile of work-sheets 12, such as loose leaf ledger sheets, bills, or other workpieces, may be placed on the open pins as in Fig. 4; the handle 20 may then be swung to the Fig. 3 position closing the pins 11, so that any number of the leaves 12 may be turned over on the pins from one side to the other to bring to the top of the pile a selected leaf.

For example, a series of leaves 12 may be placed in a pileon the right-hand pins 11, the sheets facing upward. The top sheet may then be removed and placed *on the machine 1, and typewritten entries made 7 thereon. After such entries have been made, the sheet may be placed on the left-hand pins, face downward. Each succeeding sheet in the right-hand pile may in turn be removed to receive entries and then return to the left-hand pins, so that'the order of the sheets is retained. If it is desired to select individual leaves from different parts of the pile, or series, the operator closes the holding rings by swinging the handle 20 to the right, allowing any number of leaves to be thrown over on the rings to bring to the top of the pile the selected sheet. The handle 20 may then be thrown to the left, opening the rings and permitting the removal of the selected sheet. In all these operations, the order of the sheets retained without any special thought or Jeffort on the part of the operator. The leaves are also supported and kept in a perfectlyflat condition. I

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
