PATENT @ENCE JOHN MATTIVI, OF MULBERRY, KANSAS.

BNDING STRIP.

Application filed November 8, 1921. Serial No. 513,668.

To all whom it may concern:

Be it known that l, JOHN MA'r'rivI, a citizen of the United States, residing at Mulberry, in the county of Crawford and State of Kansas, have invented certain new and useful improvements in a Binding Strip, of which the following is a specification.

This invention relates to binding strips especially adapted for use in connection with loose leaf sheets.

An important object of this invention is to provide a' binding strip for the sheets of a loose leaf book having novel means to strengthen and reinforce the sheets so that the same will not be likely to be torn when removed from or applied to a book.

A further object of the invention is to provide a binding strip for loose leaf sheets which may be employed at any time without marring the appearance of the same and which may be applied without necessitating cutting the sheets.

A further object is to provide a binding strip of highly simplified construction, neat in appearance and cheap to manufacture.

Other objects kand advantages of the invention will be apparent during the course of the following description.

In t-he accompanying drawing forming a part of this application and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a fragmentary planview of a book having a plurality of loose-leaf sheets equipped with the improved binding strips. Figure 2 is a perspective of the improved binding strip, the loose-leaf sheets being shown in dotted lines.

Figure 3 is a detail sectional view through the binding strip and a portion of the sheet. j ln the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 5 generally designates a book having a back 6 to which the usual impaling pins or rings 7 are connected. j

The invention forming the subject matter of this application resides in providing means for strengthening and reinforcing the loose leaf sheets 10 so that the same may be repeatedly removed and applied -without tearing the portions of the same adjacent the openings therein. The invention consists of a binding strip generally designated by the numeral 11 and said strip is formed from a single piece of suitably stout material folded between its longitudinal edges to provide a pair of sheet contact or sheet reinforcing strips 12, the opposed sides of which are provided with a suitable adhesive.

rihe improved binding member or strip ll is sold as a unit and is adapted to be applied individually to the various sheets l() so as to provide a means for strengthening and reinforcing the same and also causing the sheets to lie fiat when in the book. Prior to being attached to the sheets, the opposed sides of the strip 12 are connected by the adhesive and when it is desired to separate the strips l2 it is merely necessary to grip the extended edge portion 14 of one of the strips and pull the same away from the other strip l2. In this manner the strips 12 may be readily and conveniently separated so that the same maybe applied to opposite sides of the sheet 10. The reinforcing strips l2 are formed with openings 16 aligned with the openings in the sheet 10 so that the rings or inipaling pins 7 as the case may be may be readily inserted through the sheets. Reinforcing eyes 1S of a material similar to the reinforcing strip l2 are pasted or otherwise secured to the reinforcing strips l2 outwardly of the openings 16 therein.

By the use of the improved binding strips they form a reliable means for strengthening and reinforcing the sheet 10 and for causing the same to lie Hat when on the book. The improved strip may be readily and conveniently applied to the sheet l() and may be employed without the necessity of punching additional holes in the sheet.

Having thus described the invention, what is claimed is A binding strip consisting of a single length of material folded intermediate its 'edges to provide a pair of contact strips. the

opposed sides of which are formed with adhesive for irmly holding between said strips a loose leaf sheet, said strips being of a length equal to that ofthe loose leaf sheet,

one of the longitudinal edges of said Contact adapted to align when said binding strip is strips being: extended beyond the longitudifolded with openings in the loose lent' sheet. 10
