' (Cl. 281-25) Thisinvention relates to binding devices. 51 the arms in closed position. _ In Figure Z'the corresponding parts are iden material, such as sheet metal, and which can be in Figure 1, the major di?erence between the two forms residing in the fact that in the form shown secured in binding relation with facility and eco 1O 15 in Figure 2 the plane ends Ila are of a length - tions of the device. .greater than the. width of the strip I0 and the . edge of the latter to hold the binder in closed 10 position after the sheets to be bound have been strip to which the free ends of the arms are attached after the latter have been passed Any suitable tool or machine may be employed for bending the margin "id of the strip overthe through perforations in the sheets, pamphlets ends Ila. of the arms, as shown in Figure 1, or 15 in folding the ends Ila of the strip ID as shown I Figure 1 is a perspective view of one form of 20 the improved binding device. .

Figure 5 is a perspective view of an additional form of binder. ' of sheets bound by the device shown in Figure 5. Figure 7 is a perspective view of a further > - Figure 8 is a transverse section of sheets and covers bound by the device shown in Figure '7. Figure!) is apartial development of the binder. In Figures 1 to 6 inclusive the device comprises ‘a longitudinal strip‘ III from a lateral edge of which extend a plurality of parallel arms II which preferably are given the ring shape shown in Figure 3, prior to the insertion of the arms through perforations in the sheets or articles to be bound, such as perforations I2 in the sheets I3 and covers I4, illustrated in Figure 6. ‘ The strips III and arms II may be formed of sheet metal, or a plastic such as ,celluloid or other suitable material. After, the arms II have been ‘passed through the perforations in the sheets to be bound, the ends Ila, which are directed out 50 wardly of the circle de?ned by the arms, are pressed into contact with‘ and secured to the strip III to form preferably a permanent binding for the sheets. assembled in the binder. ' “ in Figure 2. ' ' - , .-In the form of the invention illustrated in ‘Figure 3 the ends Ila of the arms 'II are pro vided with perforations I5 and the strip I0 has integral lugs I6 struck upwardly therefrom. The lugs are adapted to pass through the respective perforations I5 when the sheets to be bound have been ~assembled on the arms and the latter pressed into contact with the strip. The lugs I4 ‘are then bent overvinto contact with the upper surface of the ends Ila to retain the latter in close contact with the strip In as illustrated in Figure 4. I Figure 6 is a sectional view through a number modi?cation. 55 outer portions of the former are folded over the Another object of the invention is to provide a binding ~device preferably formed of a single piece of material, having a plurality of arms of ring form which are integral with a longitudinal In the accompanying drawing illustrating ex emplary embodiments of the invention, 4 OY ti?ed bythe same reference characters employed nomically by inter-engagement of integral por or the like, to be‘ bound. 30 latter is then folded over the ends Ila to secure . - ‘One object of this invention is to provide a binder for perforated sheets,‘ pamphlets or the like, which is formed of a single piece of suitable . . In Figures 5 and 6 the strip I0 is provided with‘ 30 perforations or slots I1, and the ends of the arms have short, outward-1y directed portions I Ib which terminate in portions I I0 which are disposed sub stantially at right angles to the portions III) as shown in dotted lines in Figure 5. When the 35 sheets‘have been assembled on the arms, the ends - I Ic arepassed through the slots I1 and bent over into-contact with the lower face of the strip IE] to- retain the binder rings in closed position, as illustrated infull lines in Figure 5 and in Fig 40 ure 6.. The end portions He thus ‘function as lugs, in much. the same manner as the lugs I6 _ of the‘ modification shown in Figures 3 and 4. In all the formsof the invention above de scribed the ends of the arms, are held in close contact with the face of the strip and thus reduce the likelihood of the. perforated edges of the bound sheets,. when open, passing between the contacting surfaces of the arm ends and the strip and ‘being torn when .the sheets are turned to or 50 from closed or book-like form illustrated in- Fig ure 6. 1 . In Figures 7 and 8 the binder is also formed of a single piece of material which in this instance In Figure l the strip I0 is shownas being of a width greater than the length of the plane ends should be resilient, the binder comprising a strip 55 Ila. of the arms. The arms terminate in hooks 20 adapted to en After insertion of the arms through the perforated sheets‘ the plane ends IIa of the arms II are pressed into contact with 60 the strip I0 and the outer margin Illa of the I8 having arms I9 integral with one edge thereof. ‘ gage the inwardly turned- hook-edge 2| of the back Hi to retain the ring-like arms I9 in closed position after the perforated sheets or sheets and 60 2 2,128,625 covers 22 and 23 have been assembled thereon as illustrated in Figure 8. . _In this. form of the invention the arms can be thereof and of ring-like form extending through the perforations of the sheets, one end of each arm being integral with said longitudinal edge compressed into and released from engagement with the retaining edge 2|. This type of bind and the other ends of the arms being directed ing device can thus be used for temporarily bind-. ing sheets or the like if desired. The strip l8 pref and contacting a surface of said strip, said'strip being of a width greater than the length of said outwardly directed ends and having the other erably is convex, as shown at its rear surface and provides space for a?ixing title,‘ volume and li 10 brary or other indicia, if desired: _ In the forms of the invention» above described, the strips l0 and the ends of the arms engaging the same are disposed preferably between one cover of the book and the bound sheets although . 15 these portions of the binding may be disposed in . the middle of the book between the sheets or po sitioned at the rear edge of the bound sheets, if desired. However, a neater binding is provided and the covers can be opened back to back by 20 disposing the strip and arm ends beneath one cover, and the assembly of the sheets upon the , binder arms is also facilitated. For this reason the strips I0 and the engaging ends lld'of the arms II when in contact with a cover'preferably lie in a plane parallel with the covers. The strip and interlocked ends of the arms therefore pref erably lie in a non-r‘adial plane of the circle or cylinder de?ned by the arms. Where the strip and arm ends are to lie ‘midway of the bound 30 sheets or are ‘to extend rearwardly from the bound edges of the sheets they are disposed in a radial plane of the circle de?ned by the arms. The arms and strips of the above described de vices can be formed of relatively thin material such as sheet metal. In order that the ring shaped arms when formed of thin material shall be sumciently rigid to retain their shape and that rough edges shall be avoided, it is preferred outwardly from the respective ring-like portions longitudinal edge portion thereof folded over into close contact with said ends to secure the ends‘ 10 between'said portions of the‘strip to retain the rings in fully closed relation. 2.
