SPECIFICATION forming part of Letters Patent No. 782,420, dated February 14, 1905,

Application filed June 16, 1904. Serial No. 212,802.

To all whom it may concern.-

Be it known that we, 'THOMAS GEORGE SEARLES, residing at 867 Old Kent road, and MAURICE SHEARER, residing at 809 Old Kent road, London, England, subjects of the King of Great Britain and Ireland, have invented certain new and useful Improvements Pertaining to the Binding of Loose or Folded Sheets of Paper or other Material, of which the. fol lowing is a specification. V

This invention relates to certain new and useful improvements pertaining to the binding of loose or folded sheets of paper or other material, and has for its object to provide means whereby such sheets of paper or other material may be securely and firmly-held or locked in a binder or file whenever a required or desired number of sheets,whether one or several, may have been collected and placed therein.

The accompanying drawings illustrate the invention.

Figure 1 shows a file or hinder open and fitted with our improvements. Fig. 2 is an end view of the spring-back of the binder, showing serrated pins or prongs and metal clamping, strip, together with spring fastening-plates. Fig. 3 is a front elevational view of spring fastening-plate, and Fig. 4 illustrates in front elevational VIEWS suitably-perforated clamping-strips. Fig. 5 is a perspective view of a portion of binder.

In carrying the invention into effect the file or binder is constructed with a spring or stiff back a, Figs. 1 and 2, of metal or other suitable material, attached to which are one or more pins or prongs Z) of any suitable section. These pins or prongs I) are jointed at a to one side of the spring or stiff back a, so as to form a hinge to enable said pins or prongs Z) to be put into a suitable position to place the loose or folded sheets thereon. After any required number of sheets have been placed on the pins or prongs '6 the sheets are held in position by the clamping-strip c of suitable metal or material with perforations to correspond with the pins or prongs b aforesaid, said strip 0 being ribbed or turned over at its top to hold firmly against the sheets, and'it can be removed and replaced when necessary. In Fig. 4 are illustrated two suitable arrangements of slots or perforations in the strip 0 for the purpose.

As more particularly illustrated in Fig. 2, the pins or prongs 6 are serrated to receive the clamping-stripe, which thus firmly hold the sheets in position. The points of the pins or prongs b are made conical with shoulders,

2 at e, and the inner side, of said channel is perforated correspondingly with the perforations of the spring-fasteners d. In the channel e is inserted a strip of metal or other suitable material f, which closes the holes in the channel, thus preventing the points of the pins or prongs 6 being inserted until it is re.- quired to fasten the file or binder. When it is desired to do this, the strip fis withdrawn from the channel 0 and the points of the pins or prongs b are then enabled to be forced through the holes of the spring-fasteners. The holes in the spring-fasteners 61 being smaller in diameter than the conical heads toward the points of the pins or prongs b, thesaid pins or prongs cannot be withdrawn when .they are forced through beyond the shoulders. Hence the fastening of the file or binder then becomes permanent.

The spring or stiff back a of the binder or file may be provided with fiat or other springpieces arranged 'or placed against or near the hinging-points of the pins orprongs or in other suitable position to strengthen the same and increase the spring force, if necessary.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. In binders or files for loose or folded.

sheets of paper or other material the springback a formed with channeled edge e in combination with the serrated and conioallypointed pins or prongs b and spring fastening-plates cl substantially as shown and described. v

2. In binders or files for loose or folded sheets of paper or other material the springback a formed with channeled edge e in combination with the serrated and conicallypointed pins or prongs Z), the perforated clamping-plate 0, spring fastening-plates d and removable strip f substantially as shown and described.

In testimony whereof we have signed our names to this specification in the presence of 5 two witnesses.

THOMAS G. SEARLES. MAURICE SHEARER.
