BINDER.

SPECIFICATION forming part of Letters Patent N 0. 574,477, dated January 5, 1897. Application filed July 3, 1896. Serial No. 597,947. (No model.)

To aZZ whom it may COILCB/lb.

Be it known that we, HARRY E. DADE, residing in the city, county, and State of New York, and GEORGE FRANCIS HILL, residing in Brooklyn, Kings county, New York, citi- Zens of the United States, have invent-ed certain new and useful Improvements in Binders, of which the following is a specification.

This invention relates to binders adapted to receive and hold in convenient form sheets of paper or other fabric and to receive additional sheets from time to time, as may be required.

The object of theinvention is to provide simple and convenient means for securely clamping the sheets in place, and adjustable, so as to accommodate such additional sheets as may from time to time be added.-

The invention consists of the construction hereinafter set forth.

In the drawings forming part of this specification, and in which like letters designate corresponding parts in all the figures, Figure 1 is a sectional elevation of a binder embodying one form of the invention. Fig. 2 is a plan view, reduced, of the form shown in Fig. 1, part being broken away. Fig. 3 is a fragmental plan view of the same, the top of the casin g for the clamping means beingremoved. Figs. 4 and 5 are views similar to Fig. 3, showing modified forms of the clam-ping means; and Fig. 6 is a fragmental plan View of the form shown in- Fig. 5 with the casing intact.

Fig. 7 is a transverse view of part of the toggle and casing and showing the actuatinghandpiece of the toggle removable. Fig. 8 is a plan view of the toggle and easing, similar to Fig. 4, and showing the head of screw g removable.

In the best form of the invention two stiff covers A and B are employed, between which the sheets 0 are secured, and having hinged inner pieces co and b, respectively. The piece Z) is preferably made of metal, and has firmly secured to it two posts 0 and 0', adapted to pass through apertures cut in the sheets 0. The piece to also has apertures for the posts, whereby the cover A is enabled to slide on the posts. Supported by the piece a and adapted to engage the posts is a toggle comprising a pair of hinged or pivotally-connected toggle-arms d d. The outer ends of these arms are generally cut out to form small projections d on each side of a post. The inner ends of the arms are, of course, pivotally connected together to form a toggle-joint. In Figs. 8, 4, and 5 the toggle is shown bent and in its disengaging position, and when moved inward, so as to extend the arms, the posts are tightly clutched, so that the cover cannot be moved. provided with blocks a a to afford supports for the posts when engaged by the toggle and to afford a bearing for the top of a casing D, which incloses the toggle and is secured to the plate a, the plate or piece a forming the bottom of the casing.

We may employ various means for actuating the toggle. In Figs. 1, -2, and 3 is shown hand means comprising a wedge e, provided with a handpiece e and adapted to slide back and forth between the togglearms and a bracepiece a on the piece a. The wedge serves to throw the toggle forward into engagement with the posts. In this case we generally The piece a is generally also employ a spring to actuate the toggle in the reverse direction. It will be observed that this spring tends to hold the toggle-arms out of engagement with the posts 0 0, so that these arms when out of engaging position are kept clear of the posts and prevented from catching on the posts when'the piece a is sliding up or down on the posts. Moreover, when the cover A is removed the spring f keeps the toggle bent and retracted, so that in replacing the cover the posts may pass freely without obstruction through the apertures in the cover. The spring is preferably a flat strip of metal f, having its ends engaging shoulders on the toggle-arms, as shown,

and it may be provided with a small pin f,

set in the piece a to hold it in position. Any

convenient form or arrangement of the spring may of course be employed. The handpiece 6 stands outside the top of the casing, its

stem extending through a slot'in the easing into engagement with the wedge e.

In Fig. 4 a thumb-screw g, passing through the outer side of the casing and through a threaded projection g on the piece a, is employed to move the toggle into engagement with the posts. In this case the spring fis generally employed to serve the same purpose as in Figs. 1, 2, and 3.

In Figs. 5 and 6 an extension of the pintle h of the toggle-joint extends through a slot in the top of the casing and is provided with a head h to move the toggle into and out of engagement with the posts. In this case the toggle-arms are so arranged that the pintle it passes the dead-center line when the toggle is in engaging position, as shown in dotted lines in Fig. 5, so that the toggle is firmly held in this position until moved back again by hand. A spring, as f, is not shown in Fig. 5, but it may be there employed to hold the toggle-arms clear of the posts 0 0 when they are out of engaging position, so as to prevent the toggle-arms from accidentally catching on the posts when the piece a is moving on the posts 0 c and from obstructing the apertures for the posts in the cover A when the cover is removed.

Vhile we prefer to employ two stiff covers A and B,it is of course obvious that some of the advantages of the invention would be secured if one or both covers were dispensed with. If desired, the handpieces e and h and the head of the screw 9 may be made removable, so that only the proper person having possession 'of these parts will be able to unlock the binder, as indicated in Figs. 7 and 8.

In Fig. 7 the hand piece h has a barrel-stem fitting removably on an extension of the pintle h, and in Fig. 8 the head of the screw fits removably on the squared end of the screw g.

It will be seen that the casing D, whose bottom is the piece or plate a, loosely incloses the toggle, which has free movement back and forth therein, so that the toggle may work without obstruction or binding. The casing affords or carries the means for limiting the transverse movement of the toggle, so that the toggle is held in the casing in proper .po sition and cannot be disarranged.

In Fig. 3 the toggle works between the piece 6 and pin f. In Fig. 4 it works between the piece g and pin f, and in Fig. 5 it works between the sides of the casing.
