DETACHABLE-LEAF LEDGER.

SPECIFICATION forming part of Letters Patent No. 639,420, dated December 19, 1899.

Application filed May 29, 1899. Serial No. 718,681. (No model.)

-To all whom it may concern:

Be it known that I, EMIL MARSKY, a citizen of the United States, residing at San Jos, county of Santa Clara, State of California, have invented an Improvement in Detachable- Leaf Ledgers; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a detachable or loose leaf ledger; and it consists, essentially, of metallic bars having tooth-clamps or other fastenings coincident with slots which are made in the loose leaves through which said clamps are adapted to pass and a slidable locking strip or wire adapted to engage the section so as to secure the leaves in place, said sections being attached to flexible strips of bendable material, which are bound so as to form a book of any desired number of sections. Eachleaf or leaves of the independent sections may be removed either singly or together and others may be replaced, so that the book may be perpetually kept up by adding new leaves as soon as the old leaves are filled.

It comprises also details of construction, which will be more fully explained by reference to the accompanying drawings.

Figure 1 is a view of a ledger'opened out. Fig. 2 is a detail of a back-piece and connections. Fig. 3 shows a sheet prepared for the ledger.

In the construction of my ledger or other book I employ back pieces B, which are stitched or otherwise secured to folded strips O of flexible material, these being in turn secured to the parchment or other back D, and the latter is then fixed between the covers E of the book, forming the binding, as at O F. p

A represents sheets of paper having holes or slots a made through them at intervals along one edge, these slots being punched by machinery, so that they all exactly coincide with each other.

The backing-pieces. B have tongues or pro jections of any description corresponding with the holes made through the leaves and turned so that the leaves may fit over these tongues. In the present case I have shown the stripB having the tongues made as shown at II and projecting up from one side to aheight sufficient to receive the number of leaves designed to be placed in each section. Then the tongues turn inwardly and project slightly overand beyond the slots, through which they pass. Opposed to these tongues, upon the opposite side, the pieces B are turned up and inward, as shown at B. One end of each piece B is preferably turned up or closed, as shown at G is a sliding strip made of such width that it will pass between the ends of the bent tongues and the inward part B of the backin g-piece and being passed into the backingpiece above the edges of the paper which have been fitted thereto, this strip serves to lock these sheets firmly into the section in which they have been placed. All or any of the sections forming the book may thus be filled and arranged, as required by the uses for which the book is desired. If the book is designed to be used as a ledger or for other similar purposes where the leaves will be soon filled with completed transactions, the backing-pieces may be made of sufficient size to each receive the number of leaves devoted to each letter, as A B O, of the alphabet or if the transactions are large then a plurality of the backing-pieces may be employed for each or any of the letters, as desired, and whenever it is necessary to remove one or more leaves the slidable strip or locking device G may be withdrawn and the leaves disengaged from the hooks or clamps and removed. Other leaves may be inserted in their places and again secured. It will thus be seen that any portion of the book may be removed and renewed without disturbing the others, and this may be carried on indefinitely.

It will be understood that the arrangement of these leaf-holding backing-pieces and the like devices may be varied without materially altering the character of the invention, and the strips may have interlocking hinges and rods by which they maybe connected together without materially altering its character.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A detachable leaf -holding device consisting of metal backing-pieces having projecting tongues adapted to enter correspondingly-shaped slots or openings made along the edges of the sheets, inwardly-turned lips upon the tongues and upwardly and inwardlyv turned edges upon the opposite side of the backing-pieces and slidable locking-strips adapted to slip beneath said tongues and over the rear edges of the sheets whereby the latter are locked into the holders.

2. Devices for detachably holding independent or loose leaves consisting of metal bars having rear edges turned upwardly and inwardly, tongues or projections turned upwardly and inwardly upon the opposite edges and adapted to enter and engage with corresponding slots made along the edges of the leaves to be secured, and slidable strips, the edges of which fit beneath. the inWardlyturned back and tongues and exterior to the rear edges of the sheets which are engaged with the tongues whereby they are looked Within the holders.

3. A book comprising covers with flexible strips insertible from one end of the holder 7 so as to pass beneath the inwardly-turned edges and tongues and to press upon and lock the rear edges of the sheets in place.

In witness whereof I have hereunto set my hand.

EMIL MARSKY. Witnesses:
