LOOK FOR LOOSE-LEAF BINDERS.

To all whom "it may concern:

Be it known that I, LEONARD R. DIOKER- son, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Looks for Loose-Leaf Binders; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

In the numerous loose leaf binders heretofore constructed an objection has been found to their use because of the difficulty in protecting the ledger or binder from un authorized insertion or removal of sheets or leaves whereby the value of the record afforded by the contents might be seriously affected. In numerous instances also, the purchaser does not care for, and therefore does not require a lock in connection with such devices and it therefore necessitates in many instances, the construction of two distinct types or forms of binders, in one of which a lock is installed, and in the other of which (though otherwise perhaps a facsimile) no lock is used. This necessitates carrying double the stock on hand, and is, of course, objectionable to the dealer.

The object of this invention is to afford a construction in which the lock may or may not be employed as the purchaser may elect, and which enables the purchaser, even though the device wnen first purchased should be provided with a lock, to dispense with the same at will, and to use the same with or without the lock indeterminately at any time during the use of the device.

It is also an important object of the inven tion to afford in connection with a device such as described, a removable lock normally secured in place in the binder but which can only be removed from the binder by the use of a key, which thus permits the actuating mechanism for the binder to be operated.

It is also an object of the invention to afford in a device of the class described a shaft operated binder provided with an aperture to permit access to the shaft for operating the same, said aperture adapted to be securely closed by the engagement of a removable lock therein.

Specification of Letters Patent.

Application filed February 1, 1909.

Patented July 19, 1910.

Serial No. 475,328.

The invention consists in the matters hereinafter described and more fully pointed out and defined in the appended claims.

In the drawings: Figure 1 is a fragmeir tary inner face View of abinder embodying my invention showing the lock in place. Fig. 2 is a section on line 2-2 of Fig. 1. Fig. 3 is an end elevation of the binder back showing the binder locked by the plug ging of the aperture by means of the lock. Fig. at is a top plan view of the lock, showing the same removed from the binder and in locked position. Fig. 5 is a similar view but she-wing the lock adjusted for removal from the binder. Fig. 6 is a section of the lock taken on line 66 of F ig. 3.

As shown in the drawings: the binder back is of the three piece type comprising a central back plate A, clamping plates B-B, integrally connected with inwardly turned lateral back flanges Z), and as shown, provided with telescoping impaling posts bb which are rigidly connected on the respective clamping plates.

tigidly connected with the back plate A, at the end thereof, and affording guides for the back flanges 2), between the same and said back plate, is a transverse metallic bar C, which is supported at some distance above the inner face of the central back plate, owing to the convexity of said back plate, as shown in Figs. 2 and 3. Said back plate, as shown, is provided at each end with an end plate a, rigidly secured thereon in any suitable manner, and as shown, provided with an aperture in one end to receive the key or other tool for engaging the angular end (Z, of the right and left threaded actuating shaft D, as is usual for expanding and contracting the binder. As shown, said aperture in the end plate a, is slotted on one side to permit the insertion therethrough of the lock E, which comprises a cyllndric barrel 6, provided in one end with an aperture to receive the key 0', therein whereby said barrel may be rotated, and rigidly secured on one side of the barrel is a casing or seat 0 in which is pro vided spring impelled pins 6 in a familiar manner adapted to register with, and engage against corresponding shorter pins 6*, in the barrel and bearing on the outer ends of which are balls 6 adapted to be engaged by the wards of the key, as shown in Fig. 6,

when the key is fully inserted to adjust the shorter pins 6 in the barrel, and the pins 6 in the ward seat to a position to permit the rotation of the barrel. Secured on the outer end of the barrel is a dog F, which is adjusted on the barrel to extend at a right angle with the ward seat or case when the parts are adjusted, as shown in Fig. 6, and hence the only position at which the key can be inserted or removed.

As shown in Figs. 1, 2 and 3, a stop pin 0, is secured to the under side of the bar C, which is sufiiciently long to lie closely to the ward seat or case 6 and prevents rotation of the lock in the aperture.

The operation is as follows: Should the user desire to lock the binder, it is only necessary to insert the look into the aperture in the end plate a, after the binder is properly adjusted, and turn the key to bring the wards again into register, or to the position shown in Figs. 1, 2, 3, 4, and 6, in which position the insertion of any tool to operate the actuating shaft, is, of course, impossible. Of course, any suitable lock may be employed for this purpose by the use of which the aperture for the actuating tool may be closed. I therefore do not purpose limiting this application for patent otherwise than necessitated by the prior art.

I claim as my invention:

1. The combination with a binder provided with a key aperture and a transverse bar above the key aperture, of a lock adapted for insertion in the key aperture comprising a barrel, a casing, a rotatable member journaled on the end of the barrel and a pin secured to the transverse bar to engage the casing and prevent turning thereof.

2. The combination with a binder provided with a key opening and a bar secured above the key opening of a lock adapted for insertion into the opening comprising a casing, a member adapted to be rotated at a right angle therewith and lock in said position and means secured to the bar for preventing turning of the casing.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.

LEONARD R. DICKERSON.
