LOOSE-LEAF BINDER.

SPECIFICATION forming part of Letters Patent No. 785,750, dated March 28, 1905. Application filed December 7, 1904. Serial No. 235,823.

To all whom it may concern:

Be it known that I, PHILIP MONTGOMERY, a citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, have invented a new and Improved Loose-Leaf Binder, of which the following is a specification.

My invention relates to that class of devices employed for securing sheets of paper so that they may be readily removed and replaced at will either separately or collectively; and the object of my invention is to provide a device of this class that shall be simple and inexpensive in its construction; and a further object of the invention is to provide a device that shall be extremely simple and convenient in its method of operation and use.

A device in the use of which the above objects may be attained is illustrated in the accompanying drawings, in which- Figure 1 is a perspective View of a binder embodying my invention. Fig. 2 is a view of the blank for forming the back. Fig. 3 is a view of the blank for forming the case.

In constructing a binder in accordance with my invention I provide a case which is formed to shape from ablank 1, as shown in Fig. 3 of the drawings. This blank is preferably cut from sheet metal of proper length-and width to form when bent into the shape shown in Fig. 1 of the drawings a case having abottom That part of the blank to form the bottom is provided with projections 4:, that are properly formed to constitute part of a hinge. The blank is also formed as to those portions which are to form the ends with stop projections 5. When the case is finally formed, the lugs on the bottom are bent into tubular shape to form the members 4: of a hinge, and the stop projection is bent, preferably, at right angles to the ends 3 to form stops 5. The cover of the case is formed of a sheet of metal 6, as shown in Fig. 2 of the drawings, this part being of proper dimensions to form when bent to shape a back 7 and a top 8, the former preferably being adapted to lie against the edge of the ends and bottom of the case and the latter to overlie the upper ends of the end pieces 3 of the case. Slots 9, extending laterally of the top, are provided for the reception of pins 10, secured in the bottom portion of the case, each of the pins hearing at their outer ends a beveled portion 11. The blank forming the cover is also provided with catch projections 12, which in final form are bent, preferably, at right angles to the back of the cover, forming catches 12. The catches and stops are preferably of hook form, as shown in Fig. 1 of the drawings, and are adapted to engage and -interlock with each other. A lock-plate 13 is hinged on the outer surface of the top 8 of the cover, being secured, as by means of springs 14, which serve the double purpose of a hinge to allow a slight swinging movement of the plate and also as a spring to hold it firmly against the outer surface of the cover 8. This lock-plate is provided with openings 15, adapted to receive the pins 10.

This binder preferably includes in its construction a cover consisting of a back 16 and leaves 17, flexibly united to the back in the usual manner.

In the normal location of the parts the leaves to be bound, having first preferably been perforated with holes in proper position to receive the pins 10, are located upon the pins and the cover is in its closed position with the back 7 and the top 8 resting against the back and end edges of the case, the lockplate 13 being closed down and the pins 10 passing through the slots 9 into the openings 15, which look the parts closed. When it is desired to remove a leaf, the plate 13 is swung upward to disengage it from the ends of the pins 10. It will be noted that in this movement to swing the plate 13 to disengage it from the pins pressure is applied to the cover in a direction to swing it as to its upper end away from the case, and this swinging movement is also aided by a spring 18, secured to the bottom 2 and the back 7, which spring tends to hold the cover as to its upper end swung away from the case. \Vhcn the cover has swung the proper distance to cause the ends of the pins 10 to be disengaged and to be freely accessible, the catches 12 engage with the stops 5, limiting the backward swinging movement of the cover. It will be noted that the cover is thus maintained in a convenient and accessible position to be closed when desired, the back 16 being raised so that the hand may be readily placed behind it to close the parts, the edge of the plate 13 engaging the beveled edges 11 of the pins 10, causing the plate to be raised until the ends of the pins are located opposite the openings 15, when the plate swings down and locks the cover in position.

In prior devices of this class a difficulty has been experienced from the fact that both hands in many instances are required to release the cover from the case and when released the cover swings down flat and chiliculty is experienced in placing the hand underneath the cover to close the device. It will be seen that by my improved construction the back is always retained in a convenient and accessible position, and the device as soon the lock-plate is released is selfacting to open to an extent to allow the pins to be readily accessible for the purpose of removing or inserting papers.

WVhat I claim as my invention, and desire to secure by Letters Patent, is-

1. In a loose-leaf binder, a case, pins projecting upward from the bottom of the case, a cover hinged to the case and consisting of a back and a top rigidly secured thereto to overlie the top of the case, said top having slots for the reception-of the pins, means for locking the cover and case together, and selfacting means for swinging the cover from the case.
