BINDER FOR LOOSE-LEAF LEDGERS.

. Specification of Letters Patent.

Patented July 9, 1907.

Application filed April 19, 1907. Serial No- 369,138.

To all whom it may concern:

Be it known that 1, JOHN S. THoMPsoN, a citizen of the United States, residing at Oonyers, in the county of Rockdale and State of Georgia, have invented a new and useful Binder for Loose-Leaf Ledgers, of which the following is a specification.

This invention relates to binders for use in connection with loose leaf ledgers and its object is to provide simple, durable and eificient means whereby the leaves of a ledger can be readily placed and secured in position.

Another object is to provide leaf engaging means de signed to so support the leaves as to prevent them from becomingwedged within the binding means and interfering with the operation'thereof. Binders using telescopic leaf engaging members have heretofore been found objectionable because certain of the leaves often become wedged between the back and one end of one of the tubular members and prevent the binder from being clamped upon the leaves in the effective manner desired.

The object of the present invention is to utilize telescopic leaf engaging portions which are so positioned as to prevent the leaves from interfering with the clamping action of the binder.

Another object of this invention is to provide a binder having means whereby the fastening devices may be supported out of contact with the surface of a desk or table on which the binder is placed and therefore prevent it from scratching said surface.

With these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a plan view of the binder open, the backs being broken. away; Fig. 2 is a section on line x-x, Fig. 1; Fig. 3 is a section on line yy, Fig. l; and Fig. 4 is a section on line z'z, Fig. 2.

Referring to the figures by characters of reference, 1 and 2 designate the back plates of the binder the same being slidably mounted one upon the other and the plate 2 having guide flanges 3 at the ends thereof which lap the ends-of the plate 1 and serve to prevent longitudinal displacement of the plates. Plate 2 also has a plurality of transversely extending slots 4 each of which is disposed to receive a binding screw 5 which is disposed to engage the plate 1 so that when the same is screwed toward said plate its head will bind upon the plate 2 and lock the two plates against independent movement.

Formed along the outer longitudinal edge of each plate 1 and 2 is a cylindrical supporting bead 6 designed to bear upon the surface on which the binder is placed so as to hold the heads of screws 5 out of contact with said surface. Extending from these beads and at right angles to the plates 1 and 2 are the side walls 7 and 8 respectively of the binder. It will be noted that the lower edges of these walls contact throughout their lengths with the plates 1 and 2 as shown at 9 so that when the binder is placed in position shown in Fig. 3 the weight of the ledger will be transferred directly from the side walls 7 and 8 onto the plates 1 and Zand supporting beads 6.

Secured to the plate 7 adjacent its ends are tubular leaf engaging members 10 and extending from said wall 7 between the tubes 10 are fingers 11. Fingers 12 are secured to the plate 8 and are slidably mounted within the tubes 10 and tubular members 13 are secured to the plate 8 and receive the fingers 1.1 of plate 7.

When it is desired to bind leaves in the device herein described the screws 5 are loosened so as to permit the plates 1 and 2 to be drawn in opposite directions until limited by the contact of the screws with the ends of slots 4. The leaves, one of which has been shown at 14 in Fig. 2, are then placed upon the tubes 10 and 13 and fingers 11 and 12 and it is obvious that each leaf will rest upon two of the tubular members as shown in Fig. 2. If the leaf is supported by the tubular members 13 it will be held out of contact with the fingers l2 and therefore when the walls of the binder are drawn together there will be no danger of said leaf becoming clamped between the tubes 10 and the wall 8. Likewise should the leaf be supported by the tubular me1nbers 10 it would be held out of contact with the fingers 11. When the desired number of leaves have been placed upon the tubes and fingers in the manner de scribed the two walls 7 and 8 are drawn together so as to clamp upon the leaves and the plates 1 and 2 are then locked by tightening the screws 5.

In order that the backs of the binder may be securely edge of each of these clamping plates is preferably inclined as shown at 18.

What is claimed is: 1. A binder comprising slidably connected back plates,

means for locking said plates against movement, a side y wall upstanding from and integral with each plate, telescopic leaf engaging means extending from said walls, and a cylindrical supporting bead disposed longitudinally upon 5 each plate, said side walls contacting throughout their lengths with the plates.

2. A binder comprising slidably connected back plates, means for securing said plates in adjusted position, a longitudinally disposed cylindrical supporting bead upon 10 each plate, a side wall extending from each head and contacting throughout its length with the adjoining back plate, and oppositely extending telescopic leaf engaging members upon the side walls.

In testimony that I claim the foregoing as my own, I

' have hereto afiixed my signature in the presence of two wit 15 nesses.

JOHN S. THOMPSON.
