MICHAEL HIGGINS, OF BRAIDXVOOD, ILLINOIS.

TEMPORARY BINDER.

SPECIFICATION. forming part of Letters Patent No. 438,289, dated October 14, 1890.

Application filed July 25,1390- Serial No. 359,864- (No model.)

To all whom it may concern:

Be it known that 1, MICHAEL Hrco-nvs, a citizen of the United States, residing at Braidwood, inthe county of Will and State of Illinois, have invented a new and useful Temporary Binder, of which the following is a specification.

This invention relates to book-binding, and

more especially to the temporary binders used therein; and the object of the same is to provide abinder of this class adapted to contain bills and other papers, and which shall be an improvement upon devices of this same general character now in public use.

To this end the invention consists of the specific details of construction hereinafter more fully described, and illustrated in the drawings, in which Figure l is a plan view of this complete binder with several papers secured therein. Fig. 2 is a rear edge elevation thereof. Fig. 3 is a section on the line a: so in Fig. 1. Fig.4 is a section on the line y y in Fig. 1.

Referring to the said drawings, the letter B designates the bottom, and T the top, strip forming the back of my improved temporary binder. IVit-hin the bottom strip at about its center is swiveled an operating-screw O, having a thumb-piece P at its upper end, and the threads upon the body of this screw take into a threaded hole through the top strip T. At each end and near the center fasteningscrews F are swiveled into the bottom strip, and have reduced squared heads H at their upper ends. The top strip is provided with approximately rectangular holes, through which said fastening-screws F pass, the opposite sides of said screws being cutaway, as shown in Fig. 1, whereby they also are approximately rectangular. By this construction when the fastening-screws are properly turned the operating-screw 0 may be operated to raise and lower the top strip; but when one or more of the fastening-screws are turned at an angle to the length of the holes through the top strip the operating-screw cannot move said strip, because the threads which remain upon the two sides of the fastening-screw engage the threads upon the opposite sides of the rectangular holes in the top strip.

My improved temporary binder is prefer- In binding letters, bills, or papers then inserted in its proper place between two of the manila sheets, with its rear edge against the screws, and between the front edges of the two strips. The operating-screw O is then turned to tighten the top strip down upon the manila sheets and upon the edge of the letter, after which the fastening-screws F are turned at right angles to their former positions, so that their threads will engage those in the approximately rectangular holes in the top strip, whereby said strip is locked against movement, and the turning of the operatingscrew will not loosen the strips and permit the removal of the letter. As the fasteningscrews F have reduced and squared heads l-I, they cannot be turned except by a wrench especially adapted for that purpose, and by this means the proprietor may look within the temporary binder whatever he does not care to have removed by the clerks or bookkeepers who are to handle it. The manila sheets M are preferably a trifle wider than I 1. In a temporary binder, the combination, 7
