PAPER FASTENER Filed May 26, 1952 INVENTOR- A/f'on A-Da fon BY RNEL? Patented Oct. 30, 1934 1,978,569 Q I PAPER FASTENER v Alton Atwood Dayton, Alameda, Calif, assignor to Oxford Filing Supply Co.,Brooklyn,N. Y., 'apartnership comprising Richard A. Jonas,

Richard A. Jon as, Jr., Robert P. Jonas, Frank D. Jonas, and :Edward F. Jonas Application May 26, 19s2j,ser a1 nat aeoi 3 Claims. (01. 24-153) This invention relates in general to improvements in paper fasteners and particularly to a keeper which engages with the spaced tongues of a base member for binding papers together.

One of the prior objects of the invention is to provide an improved form of paper fastener of this type which is of simplified construction.

Another object of this invention is to provide a paper fastener construction of a nature which permits of very rapid application of the keeper to the tongued member and the locking of the tongues in place.

These and many other objects as will be described in detail hereinafter are successfully attained by means of this invention.

This invention resides substantially in the combination, construction, arrangement and relative location of parts, all as will be described in greater detail hereinafter.

Referring to the drawing,

Figure 1 shows a side elevational view of the tongue member and the keeper applied to one of the tongues;

Fig. 2 is a top plan view of the tongue member;

Fig. 3 is a plan view of the keeper showing dotted lines as the position which the tongues take when the keeper is applied to the tongue member;

Fig. 4 is an enlarged and elevational view of the keeper. 7

Paper fasteners of the type to which this invention relates comprise a base member with spaced tongues adapted to pass through apertures in the papers and through similarly spaced apertures in a keeper and then bent flat against the keeper.

In some instances the keepers are provided with slidable locks which are brought to overlie and confine the tongues. These locks are subject to misadjustment and require considerable manipulation with consequent danger of injury to the user on the sharp cutedges of the metal.

Due to the many motions involved, these keepers require an appreciable time to operate and it is the purpose of this invention to provide a keeper which simplifies, combines or eliminates many of the motions thereby assuring more rapid application, while yet retaining all the advantages of prior construction.

The invention will now be described in detail in connection with the drawing. The tongued member is shown comprising a plate 1 which is longitudinally grooved or beaded at 2 to give it rigidity. The tongues 3 and 4 are shown formed integral with the plate at eachend thereof. This associated member is old in the art and by itself forms no part of this invention.

The keeper involves the novel features of this invention. One form of its construction as shown in the drawing comprises a substantially rectangular plate 5 which is depressed at the central portion 6 to form a recess in which the tongues may lie and the flanged edges 7. Secured to the 6 5 keeper at one end is sheath 8 which has its edges folded over the flanges 7 as indicated at 11 which are securely clamped thereto so that the sheath does not move on the keeper.

Longitudinally slidable on the flanges of the keeper is the lock member 9 which is constructed similarly to the sheath 8 but its folded ends do not grip the flanges 7 sufiiciently to prevent movement thereof. In accordance with usual practice, the left hand end of the keeper is en- '15 larged or provided with bosses to prevent the sliding lock 9 from slipping off the end of the keeper. The end of the keeper opposite to the sheathed end is provided with an opening 10 of sufiicient size so that one of the tongues may pass therethrough. The lock 9 may of course be fixed on the keeper without departure from this invention.

When applying the device of this invention the papers are first slipped on to the tongued member 1 which, at that time, normally projects upwardly at right angles to plate 1 thereof. The sheath end of the keeper is then applied to the tongue 4 by merely slipping it down thereover so that the tongue is confined within the keeper. 9t The keeper is then rotated downwardly so that the tongue 3 passes through the opening 10 thereof. The keeper is then pressed firmly down a on the papers and the tongue 3 is folded down I to the dotted p osition shgwnjn Figure 3. lock 9 which, at this time is at ther'ightpis' then slid to the left over the tongue 3 locking it in the recess 6. Tongue 4 already lies in this recess as will be apparent and is held therein by the sheath 8. It will be seen that the keeper of this invention may be very rapidly secured in place with a few simple motions. It is merely slipped over tongued member 1, rotated downwardly parallel to the plate 1. The tongue 3 is swung down into the recess and the lock is slipped over.

From the above description it will be apparent that this invention involves certain principles of invention which may be produced by other physi- 110 cal constructions Without departure from the spirit and scope of this invention. The invention involves broadly a keeper having a receptacle for one tongue and a lock for the other tongue. v H

I do not therefore desire to be strictly limited to the form shown in the drawing for purposes of illustration, but rather to the scope of the invention as it is defined in the appended claims.

What I seek to secure by United States Letters Patent is:

1. A paper fastener keeper as described eomprising a metal plate having a depressed central portion forming longitudinal flanges on the sides of the plate, a sheath plate secured to the s ide flanges at one end of the plate to form a passage with the depressed central portion the metal plate having an opening th'e'rethrough adjacent the other end and a locking member longitudinally slidable on the side flanges.

2. A paper fastener keeper as described comprising a metal plate having side flanges and an opening near one end, a sheath plate spaced from and attached to the other end of the metal plate with its edges folded over said flanges and a longitudinally slidable locking member mounted on said flanges.

'3. A paper fastener keeper comprising an elongated member, means forming a longitudinal tongue receiving and retaining passage, opening upon one hd of said member, a perforation adjao'ent the other end, raised longitudinal flanges on said member spaced at opposite sides of said perforation, and a look slidably mounted on said flanges.
