DEVICE FOR HOLDING LOOSE OR REMOVABLE SHEETS OF PAPER BOOKWISE.

SPECIFICATION forming part of Letters Patent No. 760,359, dated May 17, 1904.

Application filed November 3, 1902. Serial No. 129,944. (No model.)

Be it known that I, RALPH G. WHITLOGK, a citizen of the United States, residing at No. 1130 West Eighth street, in the city of Los Angeles, in the county of Los Angeles and State of California, have invented a certain new and useful Improvement in Devices for Holding Loose or Removable Sheets of Paper Book- Wise, of which the following is a full, clear, and exact description or specification, reference being had to the annexed sheet of drawings and to the letters marked thereon.

This invention, which relates to certain improvements in devices for holding together or retaining loose or removable leaves or sheets of paper bookwise, is a further development of a certain part of the devices for the same purpose described and shown in the specification and drawings of my former applications for Letters Patent filed on the following dates: July 5, 1902, September 24, 1902, and October 14, 1902, and having the following serial numbers, respectively: 114,346, 124,652, 127,296.

tongue for each retainer, each tongue thereof passing through a hole in the opening end of each retainer and through one or more corresponding holes in the back of the device.

Upon the annexed drawings, Figure 1 is a plan of the central part of a device for holding loose or removable sheets of paper bookwise. Fig. 2 is an end elevation corresponding to Fig. 1. Fig. 3 is another plan of the central part of a device for holding loose or removable sheets of paper bookwise. Fig. 4 is an end elevation of the same. Fig. 5 is a plan of the central part of a device for holding loose or removable sheets of paper bookwise, having a curved back. Fig. 6 is an end tion.

and rod for operating said tongues into and out of the holes in the opening end of the retainers. (Shown at Figs. 5, 6, and 7.)

In the whole 'of the drawings that which constitutes my present improvement is identical; but for the purpose of clearly conveying to the intelligence of others the essential feature of invention in the whole of the figures of drawings it is here explained that the drawings illustrate how the improved retainers are applied to and rendered operative in the other parts of loose-paper-holding devices of more than one construction.

As shown by Figs. 1 to 4 of the drawings,

each retainer is marked A, and these are attached pivotally or hingewise at one end thereof by pivots or pins a to one side or edge of the back members B. In the opposite ends of each retainer A a hole 0 is formed, which when the retainer A is closed down becomes coincident with the holes 7) in the metal of the opposite side or edge of the back 'part B. In Figs. 1 to 4 the sliding bolt G, having tongues d at one side thereof, operates to hold the retainers Ain either the open or closed position by the said bolts (1, with their tongues d, being slid into the holes 7) and c or by being withdrawn from the said holes I) and c. The sliding tongues d in Figs. 5, 6, 7, 8, and 9 operate in a direction at right angles to that of the tongues (Z in Figs. 1 to, 4, this being necessary by reason of the retainers A in Figs. and 6 being attached to a curved back 13 in said Figs. 5 and 6 instead of to a flat back B, as in Figs. 1 to 4. In Figs. 5 and 6 the tongues d are operated by the crank-rod f, and each tongue (2 is connected to each crank e, as shown at Figs. 5 to 9. Therefore from this construction it follows that by moving the rod feircularly through a sufficient angle the several tongues (Z are either moved into or out of the holes Z) and c, and the retainers A are thereby either loosened or fastened at will for the purpose of removing papers from the retainers or for placing papers thereon, as may be required, it being explained that each sheet of papersuch as those marked E in Figs. 1, 2, 3, 4, 5, 6, and 7 is perforated or punched with holes at one edge thereof to enable the said sheets of paper E to be passed over or upon or removed from the several retainers A A. The holes Z) and b are provided by forming eyes along the edge of the back.

Having now described the nature of my said invention and thebest system, mode, or man ner' I am at present acquainted with for carrying the same into practical effect, I desire to observe in conclusion that what I consider to be novel and original, and therefore claim as the invention to be secured to me by Letters Patent, is as follows:

1. In a device for holding loose sheets, in combination, the cover, a curved retainer pivoted at one edge of the back and having its opposite end directed downwardly to the opposite edge of the back, a sliding tongue and means for operating the said tongue, said means extending longitudinally of the back, said retainer at its free end and the edge of the back adjacent the said free end being provided with openings to receive thesliding" tongue, substantially as described.

2. In a device for holding or containing loose or removable sheets of paper bookwise, the combination of the curved retainer, the hinged or pivoted connection of the curved retainer to the cover, the sliding bolt with tongues the latter passing into holes in the opening ends of the retainer and the corresponding side or edge of the device, and the covers of the said device, the retainers and corresponding side or edge having holes for receiving the tongues, substantially as hereinbefore described.-

In testimony whereof I have hereunto set my hand and seal, this 15th day of October, A. D. 1902, in the presence of two subscribing witnesses.
