Original application filed May 26, 1924, Serial No. 715 798. Divided and this application filed March 52.6,

1926. Serial No. 97,829. Y

This invention relates to paper fasteners and particularly to three piece fiat file -papcr fasteners for holding letters, documents, and other papers, and of the class disclosed in my copending application, Ser. No. 715,198., filed May 26, 1924, and of which the present application is a divisional application of certain subject matter claimed and otherwise disclosed therein.

The main object of the invention is the production in a fastener of this type, of improved means for securing the members together, and also to provide a three piece fastener which is adapted for more efiicient and convenient operation than that of certain fasteners now used. Still another object is to provide for a fastener of the above types which is adapted for economical manufacture and arrangement for sale.

The means I prefer to employ for accomplishing the foregoing objects together with other advantageous and novel features of my improved paper fastener which will appear as the description progresses, are illustrated in the drawing accompanying and forming part of this specification, and in which- Figure 1 is a plan of a paper fastener embodying my improvements and shown attached to a portion. of a file of papers.

Fig. 2 is a longitudinal vertical section of the same taken on the line 22 of Fig. 1.

Fig. 3 is a transverse section of the same taken on the line 33 of Fig. 1.

Fig. i is a longitudinal vertical section of a modified form of my invention.

Fig. 5 is a transverse section through the retaining member 6.

6 is a plan of the tongue covering member of the form shown in Figs. 1, 2 and 3.

Fig. 7 is a side elevation of the same, and

,Fig. 8 is a side elevation of the form shown in Fig. 4.

Like characters of reference refer to like parts in all the figures of .the drawing.

Referring to the drawing and particularly to Figs-1, and 3 thereof, the numeral 1 refers to a member having tongues 52, preferably two in number and spaced apart, and, when ready for use, bent at right angles to a main portion 3 ordinarily wider and more rigid than the tongues, whiclrare then adap ed to be pushed through a file of papers 4', such as letters, documents, manuscripts and the like.

There is also a .Washer or retaining merit her 6, provided with slots or perforations 5, through which the tongues 2 can ,be pushed after they are put through the papers "and after being put through saidslots they can finally be bent down flat on the member ,6

shown in Fig. 2. iPreffiably the member 5 has longitudinal ridges such as 7 near each of its side edges 10, and also has holding 1.6- ments in the form of projections, or abutments 8 ,in this instance in the form of hooks which arestamped or struck up from the-material of the retaining member 6, sa d ;firbi;i tments, projections or hooks being preferably in a plurality of sets, in this case two "in number, and under or by means of which a tongue covering member such as 9 and as. shown in detail in Figs. 6,7 and 8 can be secured. As shown in detail in Figs. 1 and 3, the abutments or hooks 8 are connected toand forn'ied integral with the ridges 7 and point inwardly from the same. They may be arranged and spaced in any suitable manner, and in this instance are arranged oppositely in two pairs, each of which is spaced ashort distance from the end of the fastener nearest it.

The covering member 9 as shown in plan in Figs. 1 and 6 has a main portion .31 Wider than the end portions 30, which extend b yond the abutments or hooks 8, and preferably out as fares or even with the ends of the perforations or slots 5.

The file 1 is shown of suchthickness and the members 3 as having such thickness and dimensions that the portions of the tongues which are bent down on the members 6 are very short, thus showing a situation in which the fastener is of great usefulness, especially with tongues as shown at 20. I

After the projecting portions of the tongues 2 are bent down 011 the retaining member 6, the covering member 9 is placed in position under the abutments or hooks 8 or portions of the same, by passing one end portion 30 between a pair of them from a point over the middle part of the member .6 until the wider part or end of the main portion 31 of the member 9 comes under and secured by the projections abutmcnts or hooks 8 at that part. The member 9 is then pushed on beyond this position until the other end of the portion 31 can he slipped the opposite direction under the other tWo abutments or hooks 8 on .the other end of the member 6 or in other words into the position shown in Fig. 1.

From the foregoing it will be apparent that longitudinal movements in opposite directions are employed together with a slight amount of vertical movement sufiicient to move the member 9 under the abutments or books 8. To remove the covering member 9, the latter is pushed longitudinally in opposite directions with a slight vertical movement to clear the portion 31 from the hooks 8 but said movements being in the opposite order from the movements required to put the same member 9 in place.

I also provide means for looking or firmly securing the covering member 9 in proper position after it is put through the movements above mentioned to bring it to its covering position over the ends of the bent down tonguesQ. Any suitable means may be employed for effecting this but I preferably lock or secure said member 9 by bending one end of one of the portions 30 down into one of the slots 5. This bend can also be first formed in said member 9 before it is placed over the tongue ends and the end portion of the member 30 would then require to be slightly sprung when bringing it to the desired position as shown in Fig. 1. It will be understood that the application of the above locking means is not confined to a covering member and a retaining member having the above described features but is applicable to other types which have the proper elements and dimensions.

What I claim is 1. In combination, in a paper fastener, a member having tongues to bepushed through papers, a retaining member having slots through which said tongues can also be pushed and then be bent down on said member and also having holding elements in two sets on its upper part spaced from said slots, and a covering member having an interme diate portion wider than its end portions and adapted to engage one set of said holding elements by moving it toward and under the same from a point between said sets and to engage the other set by moving the covering member oppositely.

2. In combination, in a paper fastener, a member having tongues to be pushed through papers, a retaining member having slots through which said tongues can also be pushed and then be bent down on said 1nember and having holding elements in two sets on its upper part spaced from said slots, and a covering member having a comparatively wide middle portion engageable with said holding elements and narrower end portions adapted to pass between said holding elements and to cover the portions of the tongues adjacent to said slots.

3. A paper fastener embodying a member having spaced apart tongues to be pushed through papers, a retaining member having slots through which the projecting tongue portions can then be pushed and bent down on said member, a tongue covering member adapted to be placed over said bent down tongue portions, and means to hold it in p0- sition thereon which include a portion on said member adapted to be bent into and en gage with one of said slots.

with a downwardly extending portion adapted to engage in one of said slots to se cure said tongue covering member in place.

5. A paper fastener embodying a member having two spaced apart tongues to be pushed through papers, a retaining memher having slots through which the projecting tongue portions can also be pushed and then bent down on said member, and a tongue covering member having a downwardly extending end portion adapted to engage with an end portion of the retaining member for securing it over the bent down tongue portions.

6. A paper fastener embodying a member having two spaced apart tongues to be pushed through papers, a retaining member having two slots through which the projecting tongue portions can then be pushed and bent down on said member and a plurality of holding elements on each side, and a tongue covering member having an inter mediate portion wider than the end portions and adapted to be held by means of said holding elements and into contact with which it is moved by longitudinal movements less than the length of the covering member.

7. A paper fastener embodying a member having two spaced apart tongues to be pushed through papers, a retaining member having two slots through which the projecting tongue portions can then be pushed and bent down on said member and two sets of holding hooks on its upper part, and a tongue covering member having an intermediate portion wider than the end portions and adapted to be held by means of said hooks. said tongue covering member being adapied to be moved under said hooks by alternate oppositely directed longitudinal movements of less length than the length of said covering member.
