rAPEn-FAs'rEnna.

To all whom it may concern:

Be it known that I, CLARENCE G. FISHER, a citizen of the United States, and resident of Rochester, Monroe county, State of New York, have invented certain-new and useful Improvements in Paper-Fasteners, of which the constructions disclosed in my prior ap- 15.

plication, No. 735,782, filed December 9,1912.

The objects of the invention are to pro- .vide an improvedflfastener of this type which is extremely simple in construction, inexpensive to manufacture and which will so hold the papers, when in use, that in lifting them the ends of the front and back members cannot pass through the. perforations in the papers.

A further object is to provide a front member having the above advantage and also being adaptedto support the points so that the latter may be bent in either direc- A further object of the invention is to provide a fastenerwhich may be readily attached to the top of a file of papers in order to form an extension thereof.

Other objects and the features of novelty will be apparent from the followingdescription taken in connection with the accompanying drawings, in which,

Application filed January 27, 1916. Serial No. 74,642.

showing the manner in which the fasteners are secured together in extending a file.

Referring to the drawings and more particularly to Figs. 1 and 2, 20 indicates a stack of papers secured together by a fastener which comprises a backing member or base, the main portion 21 of which is arranged on the bottom of the pile between the perforations 22 and 23 in the papers.

The portion 21 of the backing member has.

its edges struck up as shown in Figs. 3 and 4 and at its ends is provided with the flexible points 24 and 25, these points extending substantially at right angles to the portion 21.. The backing member may also include a wire structure, consisting of a body portion 26 arranged between the struck-up edges of. the portion 21, which at its ends has a plurality of loops 27, 28 through which the points2t and 25 project, as most clearly shown in Fig. 1. In order to secure the wire structure to the portion 21 of the backing member, the edges of the latter are pressed together at one or more points, as indicatedat 28' in Fig. 3. In some instances it may be necessary to cut or turn the edges at the points 28 in order to prevent buckling in the operation of pressing the edges together. In assembling theparts of the backing .member, the points 24 and 25 are projected through the loops at the ends of the wire structure and thebody portion 26 of the wire structure is forced between the edges of the main portion 21 at the points 28, the material having sufiicient elasticity to secure the portion 26 of the wire structure at the points 28. a y

The backing or base member as thus constructed consists of a comparativelystiif part extending along the bottom of the stack of paper, which is secured together by the fastener, and the flexible points projecting from the comparatively stiif portion. It will be understood that the ends of the wire structure may be formed in other shapes than that illustrated in Fig. 1, but the structure illustrated in Fig. 1 has especial advantages when used as a front member, as

hereinafter described, and, it being desirable to have'the front member and the wire structure of the backing member alike, it is considered preferable to use a structure embodying a plurality of loops as each end. One advantage of the structure illustrated in Fig. 3 is that it may be formed in dies by single operation and thus produced in large quantities at a very low cost and, furthermore, the fasteners may be sold with the two wire members, which go with each, detached therefrom, so that there will be no expense, in connection with the manufacture of the fasteners, in assembling the,

parts;

The front member illustrated in Fig. lis:

ing the points in either direction by constituting supports for the opposite sides of the points over which the points may be bent. It is desirable that the edges of the loops through which the points exten'dshall closely fit the points in order to avoid undue shifting of the front member and since the openings 22 and 23, which are made by the perforators commonly in use, are relatively large, theouter loops28 are provided to prevent the ends of the fastener working through the openings when the papers are lifted or turned back over the top of a stack; Theouter loop at each end is preferably of rectangular form so that the papers may bebent oversubstantially straight portions 29, thus avoiding, to a large extent, mutilationof the papers by the fastener.

In Figs. 5 and 6 another form ofthe invention isillustratedaud in this form the body portionof the backing member is channelshaped, as'indicated at 30, and has laterally projecting flanges 31 on its opposite sides with inwardly turned ears32 adapted to retain the wire structure 33 in position.

The form shown in'Fig. 7 is thesame as that shown in Fig. 3, with the exception that the edges are not pressed together as at the points 28 in Fig. 3.

In Figs. 8 to 12, inclusive, various forms of the wire structures are illustratedand it will be noted that each of these structures 1 has its end portions prcvided with a plurality of l0ops,'one within. the other,-so that the various forms are equivalent to the form illustrated in Fig.

' In Fig. 13- thereis illustrated the method of building up or "extending a file'when the i capacity of the original fastener has been 'e xtenjfsjion fastener and papers may then be (arranged on the 'points37' and 38 ofth'e latter "in-the usual way, a front member39' being,

; of. course, "employed" t'ojretain the papers in reached. extending the file thefront member is removedand the points 34: and 35 are'projectedthrough the endloops ofthe backing member of the extension fastener,

the points then being turned outwardly against the top sheet of the original file. This, Secures the backing member 36 of the position.

It will be evident to those skilled in the art that the parts may be arranged in various combinations and accomplish the results sought and while I have illustrated several modifications and arrangements, 1 do not limit myself to these forms of the invention but claim all equivalent constructions and arrangements which are within the scope of the appended claims.

Having thus described the invention, what is claimed and desired to be secured by Letters Patent is: f

1. A paper fastener comprising a backing member provided with flexible points adapted to be arranged at substantially right angles to thebody thereof, and a front member made-of'wire and havingat each of its ends a plurality of loops one within the other through which'said points are adapted to pass, the front member being secured by bending the points into a plane substantially parallel with the front member.
