This invention relates to loose leaf binding devices and its general object is-to provide a device that is primarily designed for, binding perforated loose leaves or sheets, particularly in g I pamphlet or book form, with or without covers, ranged longitudinally adjacent one edge thereof.

and which is separate from and can be quickly and easily applied to the sheets, and to the cover when a cover is used, to bind the same one-to the other, and can be quickly and easily removed therefrom to permit the sheets to be separated. take various forms and may be assembled in A further object of the invention is to provide 1 such a binding device which will permit the sheets to be easily turned and to lie flat in an open position.

A further object of the invention is to provide shaped members, each member having its .ends

such a binding device in which superposed binding members extend through the sheets to be bound and are so arranged that each member will prevent the removal of sheets from the other 1 member.

' -nfurther object is totpr ovide aebinding ldevicesn that is simple in construction, neat in appearance, inexpensive to manufacture, and extremely efficient in operation, use and service.

This invention also consists in certain other features of construction and. in the combina tion and arrangement of the several parts, to be hereinafter fully described, illustrated in the-accompanying, drawing and specifically pointed out in the appended claims.

- In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure l is a fragmentary top plan view illustrating oneform of my device applied to s.

pamphlet with the latter in closed position.

Figure '2 is a similar view with the pamphlet in open position and with only one of the sections applied thereto. Figure 3 is a similar view with the pamphlet in open position, and with both of the sections in applied position.

other member. The two members'of each pair enable the member last inserted to be sprung and when a plurality of pairs of ring shaped is immaterial except that the spacing in the two single piece of material.

tivelynarrow straight longitudinal strip 3 hav- In this drawing 1 have illustrated one embodiment of the invention, together with certain minor modifications thereof,- but it is to be understood that the several parts of the device may various ways without departing from the spirit of the invention.

As here illustrated the device comprises one or more pairs of superposed substantially ring spaced one from the other to provide an opening which enables the member to be inserted through the perforations in the sheets to be bound, each member c'losingthe opening in the may he superposed or g on the other by insert ing them successively and in opposite directions through the perforations in the sheets, and preferably one or both members is ,or are resilientvto over the member first inserted. Each member is attached-at one end to a second member, such as an elongate strip, which prevents that end thereof from passing through the perforations,

members are used the elongate members serve to connect the corresponding ring shaped members of the several pairs one with the other. The spacing between adjacent ring shaped members parts or sections of the device mustbe the same. The sectionsmay be formed of any suitable material, such as sheet metal, Celluloid or the like and preferably each section is formed from a In the particular form illustrated in Figures 1 to 6 inclusive, the companion sections are broadly indicated by the reference numerals I and 2 respectively, and the section I includes a relaing formed on and along one longitudinal edge thereof, in equidistantly spaced relation with each other, a plurality of substantially ring shaped fingers 4 that extend laterally from the strip and have their free ends disposed in close proximity thereto, as best shown in Figure ,4. Formed on the opposite longitudinal edge of the strip throughout the length thereof is a flange 5 that is curved toward the strip for cooperation with a list face thereof to provide a channel 6.

The section 2 likewise includes a relatively narrowstraight longitudinal strip I of a lengthcoextensive with that of the strip 3 and having formed on one longitudinal edge thereof, a plurality of substantially ring like fingers 28 spaced one from the other the same distances that the fingers of section I are spaced and having their free ends spaced from the strip 1. In fact, the two sections are identical, with the exception i that the strip I is not provided with afiange, and when the sections are in use, the strips 3 and-I are disposed in face to face engagement, with the longitudinal edge, of the strip 'I mounted in the channel 6 of the section I, to hold the strips against relative lateral movement, as best shown in Figure 6. When the binding device is to be applied to a group of sheets or a pamphlet the fingers of one section of the device are inserted through the perforationsin the several sheets from one side of the group with the elongate memb'er'or strip I extending along the edges of the sheets. The fingers of the other section are then inserted through the same perforations from the other side of the group of sheets and in so doing are sprungover the corresponding previously inserted fingers and the elongate member moved into face to face contact with the elongate member of the first section. When no cover is provided the elongate members or strips usually extend along the bound edges of the sheets but they may, if desired, be arranged between the sheets. When covers are provided it is usually preferable that the elongate members be arranged between the back eover and the last sheet. To accomplish this the fingers 4 of section I may be inserted through the perforations in the back cover B from the inner side of the latter, as

ing them first through the perforations in the sheets, then through the perforations in the front cover and are, of course, sprung over the fingers 4 in so inserting them. Ordinarily the fingers 8 do not extend through the perforations in the back cover. When the-strip 3 of section I is provided with a flange 5 the outer edge of strip 1 of section 2 is placed in contact with the strip 3 on the inner side of the fiange 5 and as the fingers 8 are sprung over the fingers 4 the strip 1 is moved to a position parallel with the strip 3 with its outer edge beneath the fiange 5. A convenient method of applying the device is to arrange the sheets in apilewith the front cover A on the bottom, to then fold the back cover B under the front cover with its outer face in contact with the outer face of the front cover and to' then insert the fingers of section I upwardly through the alined perforations, and to thereafter insert the fingers of section 2 downwardly through said perforations.

The binding device may comprise any suitable number of pairs of fingers and one or more devices may be used in binding a single group of sheets or pamphlet. In the form shown in Fig. 7 the device includes -a single pair of fingers, 9 and III, which are similar to the fingers 4 and 8 of Figs. 1 to. 6, and while the strips or elongate members II and I2 of this form are similar to the strips of the form shown in Figs. 1 to 6they are of course shorter due to the use of a single pair of fingers. It will be obvious theta single device of the form shown in Fig. '7 can be used alone to bind the sheets,. particularly to bind narrow sheets or cards, or that any. number of such devices may be used for binding a single group of sheets, such as a pamphlet or the like, either with or without covers.

i The flange 5 shown in Figs. 1 to 7 is preferable when it is desired to prevent the relative lateral movement -or separation of the elongate members or strips and to reenforce them, such as in the case of rather large or heavy pamphlets orthe like, but in many cases the fiange may be' omitted as a fiat strip usually has ample strength and the strips have little tendency. to

the strips I5 and I6 are fiat, the fiange being omitted. The two sections are thus connected one to the other only by the superposed fingers and while the strips may at times separate slightly one from the other this will not interfere with the operation of the binder and the flangeless form of the device is entirely satisfactory in use and in many cases is preferable to the flanged-form of the device.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes'fall within the scope of the appended claims.
