:VPAPE'R-FASTENER. i

Specification of Letters Patent. Application filed F brua y 24, 1906. Serial no. 302.698.

Patented Oct. 30, 1906.

To all whom itmay concern: Be it known that I, JOSEPHICLAYTON Lo- I GAN, :a citizen of the United States, residing at Atlanta, in the county of Fulton and State ofGeorgia, have invented a new and useful Paper-Fastener, of which the following is a specification. C.

This invention relates to paper-fasteners, and has for-its object to provide a comparatively simple, and inexpensive fastener for holding together a file of papers which must be added to from time to time and for receiving such additional papers as are necessary to complete the file.

A further object of the invention is to provide a fastener the shank of which is provided. with a terminal point adapted to pierce the papersto be filed, said shank being locked in-engagement with the papers by a removable'cap or disk.

. A further object is to form the cap with oppositely-disposed spring locking members adaptedto engage the pointed terminal of the shank, and thereby prevent accidental displacementof the same.

A- still further object of the invention is to generally improve this class of devices so as to increase their utility, durability, and efficiency, as well as to reduce the cost ofmanufacture. I i

With these and other objects in view the invention consists in the'construction and novel-combinationand arrangement of parts hereinafter fully described, and illustrated in the accompanyingdrawings, it being understood that various changes in form, proportions, and minor details of construction may be resorted to within the scope of the appended-claims.

In'the accompanying drawings, forming a part of. this specification, Figure 1 is a perspective 'view 'of the piercing member or shank of the fastener. Fig. 2 is a similar view showing the base in. position on the shank. Fig. 3 is a top plan view ofthe locking-cap detached. Fig. 4 is a perspective view showing the cap in position on the shank or iercing member.

imilar characters of reference indicate corresponding parts in all of the figures of the drawings.

The improved fastener comprises a shank or body portion 1), preferably formed of a single strip of metal or other suitable material,

one end of which is provided with a piercing point, while the opposite end thereof isbent upon itself and extended laterally in opposite directions to .form a base a.

Associated with the shank b is a cap or looking member, c, preferably circular in form, :asshown, and provided with an elongated slot or opening e .for the receptionof theshank b and having its sidewalls extended inwardly to form central projections h, adapted to engage the shank b when the rlatter is bent downwardly ontop of the cap, as best shown in Fig. 4 of the drawings.

The cap 0 is provided with oppositely-disposed concentric circumferential slits 'L,

spaced inwardly from the peripheryof the cap, the severed portion of the capbeing upstruck and spaced from-the top of the latter, thereby to form spring locking members d, adapted to. receive the pointed terminal ofthe shank b, as shown.

The locking-members d are each provided with ofiset portions or shoulders 1', adapted to engage the adjacent longitudinal edge of the shank b when the cap is rotated thereby to limit the rotary movement of said cap. In some casesthe shank (1 may be provided with a plate or disk f, the marginal edge of which is bent upwardly to form an annular flange 7c, adapted to bear against the basea, and thereby lock the parts together.

In operation the ointed end of the shank b is threaded throug the prescriptions, bills,

or other papers to be filed and thence passed through 1 the opening e and bent substantially at right angles, as shown. The cap a is then artially rotated, which causes the adj acent ocking member or lip d to engage the pointed terminal of the shank, and thus hold the several papers securely bound together.

In order to release the papers or to add additional papers to the file, it is merely necessary to rotate the cap 0 in the opposite direction, when the pointed end of the shank b will be released from the locking member d, thus permitting the same to be bent laterally to a perpendicular position and the cap 0 removed, so as to permit the filing of the additional papers.

Attentlon is called to the fact that the projections it have a tendency to bite into the walls of the shank b, and thus assist in holding the shank in bent or locked position, while the size of the opening e permits the cap to be partially rotated, so as to release or look the From the foregoing description it will be seen that there is provided an extremely simple, inexpensive, and efficient device admirably adapted for the attainment of the ends in view.

What I claim is 1. A paper-fastener comprising a shank having a pointed terminal, and a ca provided with an opening adapted to receive the shank and having circumferential concentric slits formed therein, the metal at said slits being upstruck and spaced from the cap for engagement with the pointed terminal of the shank.

2. A paper-fastener comprising a shank, and a cap having an elongated slot formed therein for the reception of the shank and rovided with oppositelydisposed spring ocking members adapted to engage said shank, there being rojections extending inwardly from the wails of the slot and adapted to bear against the shank.

3. A paper-fastener comprising a shank having a pointed terminal, a cap having a central opening formed therein for the reception of the shank and provided with concentric slits disposed inwardly from the periphery of the cap, the metal at said slitsbeing upstruck and provided with offset portions defining spring locking members adapted to engage the pointed terminal of the shank.

4. A paper-fastener comprising a shank having one endthereofbent upon itself and extending laterally in opposite directions to form a base and its opposite end provided with a pointed terminal, a cap having a central opening formed therein for the reception of the pointed end of the shank and provided with oppositely-disposed spring locking members disposed concentric with the opening in the plate and adapted to engage said shank.

5. A paper-fastener comprising a shank having one end thereof bent upon itself and extended laterally in opposite directions to form a base and its opposite end provided with a pointed terminal, a cap comprising a fiat metal disk having an elongated opening formed in the center thereof for the reception of the shank and provided with concentric circumferential slits spaced inwardly from the periphery of the cap and struck up to form spring locking members adapted to engage the shank.

6. A paper-fastener comprising a shank having one end thereof bent upon itself and extended laterally in opposite directions to form a base and its op osite end provided with a pointed termina a plate secured to the base, and a cap com rising a circular metal disk having an elhngated opening formed in the center thereof for the reception of the shank and provided with concentric circumferential slits spaced inwardly from the periphery of the disk and upstruck to form spring locking members adapted to engage the pointed terminal of the shank, the walls of the slot being provided with inwardly-extending projections adapted to bear against the shank when the latter is in engagement with the adjacent locking member.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
