Specification of Letters Patent.

Patented Aug. 21, 1906..

Application filed July 7, 1905. Serial No. 268,664.

To all whom it may concern.-

Be it known that I, FREDERICK A. CLEVE- LAND, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Binders, of which the following is a specTfication.

This invention relates to a device which may be applied to binders of the loose-leaf type, the object being to provide a device of simple construction which may be used in connection with covers or binders of this class, which may be easily operated, and which will be positive in its action. The use of binders of this description is well understood, and it is not thought necessary to enter into an explanation oftheir operation further than to state the principal requirement, which is that any number of pages or leaves may be inserted, replaced, or taken out with out disturbing the remaining leaves.

The object of my invention is to provide a device which shall meet this requirement and accomplish the desired result by the use of a simple locking mechanism which does not require separate keys or other devices to operate the same and which shall be self-contained and operated by turning the book on one side to lock the covers in any desired position and to release the same by simply reversing the position of the book. To accomplish this result, I provide an upper and ower clamping-section which may be attached to the covers of the binder. These clamping-sections are normally held apart by the action of springs contained in telescoping members attached to said clamping-sections in the usual manner. Attached to one of these clamping-sections, preferably the upper, I provide a post which carries an oscillatory pawl or dog which is adapted to engage projections on the interior of a cooperating post or casting which is secured to the lower clamping-section. This latter post or casing is adapted to telescope over the post carrying the pawl or dog. The construction of these parts is such that when the clamping-sections and attached covers are in the position shown in the drawings a free inward movement is permitted and the leaves are held between the clamping-sections by pressing the upper cover down. The pawl or dog carried by the inner post will engage the projections on the inner surface of the outer post or casing and so hold the parts in position.

The construction and operation of the de' vice will be more fully explained in connec- In Fig. 1 at l and 2 are shown an upper and i lower clamping-section, respectively, which may be attached by any suitable means to the cover of the binder, or, if preferred, the covers themselves may form the clampingsection and have a locking device attached directly thereto.

At 3 3 are shown telescoping members con taining springs which operate normally to separate the clamping members 1 and 2 when not held in position by means of the locking mechanism carried by the post 4 and the casing 7. The operation of this locking mechanism is on the principle of a pawl-andratchet device.

and mode of operation of the oscillatory pawl,which is so designed that the outer end thereof will engage projections on the interior of the casing 7 when the covers are in one position and will drop out of engagement with the said projections, allowing the clamping members and covers to be separated when the same are reversed in position.

At 4 is shown a post which 1s secured to the upper clamping member 1 by any suitable means and preferably in such a manner that it may be rotated in relation to said clamping member. This may be done by socketing the post 4 in the clampin member 1 and holding the same in position by means of an ordinary flat-headed screw, as shown in the drawings. This screw may be secured in the post 4 by any suitable means, and by The distinguishing features of this device are found in the construction using an ordinary screw-driver in the slot thereof the post may be rotated as desired. At the lower end of this post 4 is provided a recess or slot, in which is carried a pawl 5,

which is pivotally supported therein at 6.

This slot is so shaped as to provide a stop to limit the movement of the pawl, so that in one position the outer end thereof will engage the projections on the interior of the casing 7 and in the other position will be out of engagement with the said projections and allow the parts to be separated.

The pawl 5 is preferably in the form of a segment of a circular disk having two flat sides thereof adapted to engage the walls of the slot to limit the movement thereof, as above described. A portion of this pawl is formed with one or more projections adapted to engage corresponding projections on the interior of the casing 7. The pivot 6 is so locatedthat gravity will operate to oscillate the pawl about this pivot as the covers are turned from one position to a reverse position. In one ofthe aforesaid positions the projections from said pawl will engage the projections on the interior of the casing 7 and prevent the parts from being separated. In the reverse position the pawl will be rotated by gravity about its pivot and the above-described projections will swing out of'engagement and allow the members to be separated for the removal of leaves, replacing leaves, 800. It will be seen that when the covers are in the reversed position just referred to that the telescoping members 4 and 7 are free to move in and out, and when the covers are reversed the pawl will oscillate about its pivot into the position shown, and-the projections from said pawl will engage the projections on the interior of the casing 7, which are preferably in the form ofa screw-thread. The post 4 and the attached pawl may be rotated after pressing the clamping members to gether, and so effect a further tightening of the aforesaid. clamping members and insure the leaves being held securely in place. The casing 7 may be secured to the lower clamping member 2 by threading the same therein as shown or by any othersuitable means. This casing is adapted to telescope-over the post 4 andhas the inner'surface thereof provided with serrations or projections which are preferably in the form ofa screw-thread'or The object of projections of this kind has already been described.

The recess or slot in which the pawl is 10- cat'ed has the upper portion thereof so formed as to provide a stop to limit the movement of the pawl whentlie same drops out of engagement with the outer casing when the members are reversed, as already described. The

rear portion of this slot is adapted to form a stop to limit'the movement of the pawl in the opposite direction and to hold the same in such a position'tha't the projections fromthe pawl will engage the projections on the interior of'the casing 7, as already described. In this position the upper cover may be pressed down and will beheld in the position to which it is somoved by the operation of the several parts, as shown.

'It will be noted that the device herein shown and described as an illustrationof an operative embodiment of my invention is composed of a very small number of parts and that such parts are of a simple construetion and maybe easily and cheaply manufactured. It will be also noted that the device when assembled is very compact inform and that the operating parts are selfcon tained within the same.

I do not confine myself, however, to the exact details of construction shown and described, as it will be evident that various modifications and changes may be made therein to adapt the device to its several uses without departing from the scope of my in-- vention.
