UNITED STATES PATENT UFFTE WILLIAM C. GOSS, 0F MINNEAPOLIS, MINNESOTA.

LOCKING-SLIDE FASTENER.

To all whom it may concern Be it known that 1, WILLIAM C, Goss, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Looking- Slide Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention has for its object to provide an extremely simple, eflicient and low cost so-called loose leaf file fastener, meaning thereby, a device for binding together a plurality of loose leaves, papers, cards, or other matter; and, to suchends, generally stated, the invention consists of the novel devices and combinations of devices hereinafterrdescribed and defined inthe claim.

The invention is illustrated in the accompanyin'g drawings wherein like char-, acters indicate like parts throughout the several views.

Referring to the drawings,

Figure 1 is a perspective view showing a bundle of loose leaves bound together by one of my improved fasteners, and

Fig. 2 is a perspective view with some parts broken away, showing the overlappedends of the fastener and the slide for locking together the overlapped ends thereof.

The loose leaves are indicated by 1 the numeral 5. The numeral 6 indicates the binding element, which is preferably a thin narrow metal strip or ribbon bent into rectangular or looped form when completely applied. This strip 6, primarily,

is a straight strip and is adapted to be bent into U-shaped form having a span corresponding to the distance between the centers of the perforations 5 in the leaves 5,'so that the ends thereof may be passed through the said perforations and then bent over onto the face of the upper leaf with the ends over- Patented Nov. 4, 1919.

lapped. The overlapped ends are then secured by a slide 7, which is preferably in the form of a flat loop, of such size that it may be slipped onto the overlapped ends under sufficient friction to prevent accidental sliding movement thereon. When this slide 7 is forced onto the overlapped ends of the binding strip, it will securely hold the same,

as shown in Fig. 1.

Preferably, the binding strip 6 is made of flpliable sheet metal, which, while having su cient stiffness to maintain any form in which it is bent, nevertheless, may be readily bent into the desired form, so that its overlapped ends may, as occasions may require, be bent upward into parallel relation for the removal of secured leaves, or the insertion of other leaves, and then be bent backto overla ped form, without breaking. Obviously, t e cost of such fasteners, as shown in Figs. 1 and 2, is very low. Moreover, when applied, they have a very neat ap earance and are efficient for the purposes had in view.

What I claim is a A fastener for loose leaves, papers, cards,

or other matter, comprising an integral pli- WILLIAM 'C. GOSS.
