BINDER.

SPECIFICATION forming part of Letters Patent No.434,160, dated August 12, 1890.

Application filed May 21, 1890. Serial No. 352,587. (No model.)

Fig. 2 is a plan view of the binding mechan ism removed from the covers; Fig. 3, a crosssection on line 3 of Fig. 2, looking in the direction of the arrows; and Fig. 4 a similar section illustrating a modification.

A A are the covers of the binder; B, the back; C, the fixed portion of the binder; D, the binding-arm, and E a lock or catch.

The covers and back of a binder embodying my improvements are made of canvas or other suitable material, the covers being preferably stifiened in any suitable manner, as by means of card-board. To the back is secured the fixed part C of the binding mechanism. As shown in Figs. 1, 2, and 3, this con sists of a piece of sheet metal of any proper dimensions bent over upon itself longitudinally and having its edges 0 c then bent inward toward the back and inclining toward each other, as shown in Fig. 3, thus forming a substantially triangular opening along one side. I next make the binding-arm D. This consists, preferably, of a solid strip of wood, metal, or other material, of any suitable length, of a substantially triangular cross-section, and having its sides preferably slightly hollowed out, as shown in Fig. 3. This arm is pivoted between the edges of the part C, at a point near one end thereof, and with its thinner edge turned toward the opening between the edges 0 0, so that as the arm is swung inward toward the part C these edges may engage with the beveled sides of the arm and bind or press against the same. To hold the arm in place, I prefer to provide a spring-catch E, adapted to lock over the end of the arm, as shown. means for accomplishing this purpose may be used instead of this catch, as desired.

I have so far described the device as comprising a hollow resilient metallic fixed piece and a solid arm pivoted therein and adapted to engage with and be bound between the elastic springing edges thereof. In Fig. 4this arrangement is reversed, the fixed piece being made solid of wood or other suitable ma-- terial, provided with a longitudinal opening 0, and the binding-arm of sheet metal or other resilient material adapted to enter the opening 0 and be bound and held therein by its resiliency. If desired, both parts may be made of sheet metal or other resilient material, or both solid, this being but a change of material and form and wholly within the spirit of my invention.

In using the binder the catch E is drawn back and the arm D turned out of the way. The sheets to be bound are then inserted into the opening 0 between the edges of the piece C, and the arm being swung around into the opening and caught by the catchE binds the sheets between its outer edge and the edge of the piece C and holds them firmly in place.

I claim 1. A binder comprising the covers A A,a piece C, attached thereto, having a substantially triangular opening 0 along one edge, a binding-arm D, of a substantially triangular cross-section, pivotally attached to the piece C and adapted to engage with the opening 0, and means for holding such arm in place, substantially as described.

2. A binder comprising the covers A A, a piece C, of resilient material, attached thereto, having its edges bent so as to form a substantially triangular opening 0, a solid bindingarm D, pivot-ed in the piece C and adapted to enter the opening a therein and be bound between the elastic edges 0 0 thereof, and a spring-catch E to hold the arm in place, substantially as described.
