ANTHONY PAGLIUGHI, OF FORT LEE, NEW JERSEY, ASSIGNOR TO GEORGE MGKIBBIN, OF NEW YORK, N. Y.
. PERPETUAL LEDGER.
SPECIFICATION forming part of Letters Patent No. 681,001, dated August 20, 1901.
Application filed May 18, 1901. Serial No. 60,808. (No model.)
. lowing is a specification.
This invention relates to that class of bindgj ers known as temporary ledgers, and in IO y replaced by first unlocking the binding mechwhich any of the-leaves may be removed or anism.
The invention conslsts 1n improved means by which a ready locking and unlocking of i 15 said binding mechanism may be effected.
In the accompanying drawings, Figure lis a longitudinal section through the binding y. mechanism of' the perpetual ledger on line with the racks.
1l, Fig. 3, showing the hooks in engagement F1g. 2 1s a similar section showing the hooks dlsengaged. Fig. 3 is a `horizontal section on line 3 3, Fig. 4; Fig. 4,
a cross-section on line 4 4, Fig. 2; Fig. 5, a detail of the hook and rack, and Fig. 6 a detail of part of the slide g.
\ The letter a represents the cover of the book, and a' is its flexible back. This back is provided along one side with two rails b b', separated by means of stays b2, and along the other side Witha single rail c. From the inner rail b project three tubes CZ d CZ, that telescope corresponding tubes e e e, projecting from rail c. The tubes e e are provided on their inner face with teeth to constitute racks e2, Fig. 5, which are adapted to be engaged by hooks or pawls f, pivoted within tubes d at f. The pawls are connected at their upper ends to a sldp g, movable between the rails b bl and guided by means of slots g, which are engaged by some of the stays b2. The
slide may bemoved in one direction by means of a key h, inserted through keyhole h' of rail d b, so as to swing the hooks f out of engagement with the racks e2, Fig. 2. When the key is withdrawn, a spring j will return the slide to its normal position and throw the hooks into reengagement with the racks, Fig.. 1.
rlhe connection between the slide g and the hooks f I prefer to make iiexible, so as to produce a yielding engagement between hook and rack. To this effect the upper ends of the 4hooks pass through elongated slots g2 of slide are to be removed or replaced or new leavesr are to be added, the slide g is moved, by means of the k'ey, so as to disengage the hooks and permit the telescopingtubes d e and ol c t0 be separated.
What I claim is-- l. A binder provided with telescoping tubes, racks formed within one set of said tubes, hooks passing through the other set of said tubes, and a slide to which the hooks are connected, substantially as specified.
2. A binder composed of a pair of rails, telescoping tubes connected thereto, a slide,hooks yieldingly connected to the slide and projecting through one set of tubes, and racks formed on the other set of tubes, substantially as specified.
Signed by me at New York city, county and State of New York, this 17th day of May,
A. PAGLIUGHI. Witnesses:
WILLIAM SCHULZ, F. v. BRIESEN.
