Specification of Letters Patent.

Patented June is, 1907,

To all whom it may concern.-

Be it known that I, FRANCIS ROBERT BA- KER, a subject of the King of Great Britain, residing in Birmingham, county of Warwick, England, have invented certain new and useful Improvements in.Temporary Binders, of which the following is a specification.

This invention relates to temporary binders, and the object of the invention is to provide improved -means whereby the usual mating prongs used in such devices are held togetb er and separated when desired, the device having the advantages of simplicity of construction and great ease ofmanipulation.

With these ends in view the invention consists in the. novel features of construction to be hereinafter described and claimed.

Referring now to the drawings, Figure 1 is a part sectlonal side view of one form' of device made in accordance with this invention showing the mating prongs intheir norma or closed positions; Fig. 2 is a similarview showing the mating prongs in their open positions; Fig. 3 is a cross section on line X X Fig. 1, and Fig. 4 is a cross section on line Y Y a and b are the two members provided with the usual mating prongs c c and d d, the mem' ber a which consists of a rod being adapted to be slidden longitudinally and artially rotated within the'member b which is tubular. The member. I has a continuous longitudinal slot in which the prongs c, c are movable and said slotis suitably cut away at e e to receive the stemsofthe prongs c a when the member a is partially rotated.

'f is a knob or the like at the end of the member a which extends .beyond the member I) and bywhich the former may be conveniently handled. g is a 'sprin disposed helically around the member a an adapted to be com: pressed between the shoulder h on said member a and a shoulder is at the end of the member b when the member a; is slidden longitu- -dinally in the member 1), the prongs c 0 engaging with the shoulders formed at the cut away parts e e when the member a is partially rotated inthe member I; thus holding the member a in the open position against the action of the spring 9.

, In use the prongs c c are first separated longitudinally from the prongs d d by sliding the member a'in the member 1) against the action of the spring g and then laterally separated by partially rotating the member a in the member I), the device being held in the open position by the engagement of the prongs c c in the cut away parts or notches e e. The loose leaves having been placed in position on the prongs the member a is partially rotated and as soon as the'prongs c a have disengaged .from the shoulders of the cut away -parts e e the spring 9 returns the member a and prongs c c to their normal positions. Suitable means may be provided on the tubular member b for binding.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is A temporary binder comprising a tubular -member having a continuous longitudinal slot with. notches therein and a shoulder at one endof said member, said member, a rod slida le in said mem beriand extending beyond the same at one end, prongs-formed on said rod and slidable in said longitudinal slot to coact with the prongs of said tubular member, a-spring embrac' said rod at one end-portion and interpose between a shoulder 'thereonand the shoulder of the tubular member, and a .knob.on the end of said rod'which extends beyond saidtubular member.

In testimonyj 'whereof I have signed my name to this specification in the presence of two subscribiiggqwitnesses.
