2 Claims. (01. ,24-153) v (Granted under, the act of March 3, 1883, as
- 1 The invention described herein may be manufactured and used by or for the Government for governmental purposes, Without payment to me of any royalty thereon. This invention relates to paper file fasteners formed from flexible, non-metallic materials and more particularly to an improvement in the paper fastener disclosed in my pending application Se-' rial No. 560,833, filed October 28, 1944, now'Patent No. 2,468,072, dated April 26, 1949.
' In the above-mentioned application a paper fastener made of light Weight, flexible non-metallic material is disclosed, said fastener including a base member with spaced tongues, acompressor plate having apertures therein adapted to receive the tongues and a separate keeper adapted to grip each of the spaced tongues of the fastener at two points and force the tongues into frictional engagement with each other, thereby preventing the tongues from slipping out of the keeper and binding papers together tightly, with the paper fastener not being easily separated.
It is an object of, this invention to provide an improvement in the above-mentioned paper fastener by providing keeper means comprising pairs of slots formedas-an integrafp'art of the pressure pl'ate, thereby reducing the number ofparts of the paper fastener and producing a flexible non-metallic paper file fastener that is simple and durable in construction, economical to manufacture and efiicient in its operation. v v 7 Another object of the invention is to provide a flexible, non-metallic paper file'fastenerthat is capable of binding papers together as securely as file fasteners made of metal and affording the facilities of ease and speed in using.
With the above and other objects and advantages in view, the invention consists of certain features of construction and operation of parts which will hereinafter be described and shown in the accompanying drawings in which:
Fig. 1 is a perspective View of the file fastener ready for assembly;
Fig. 2 is a perspective view of the file fastener completely assembled; and
Fig. 3 is an elevational view in cross-section of the file fastener completely assembled showing the relation of the parts thereof.
Referring more specifically to the drawings, the parts of the improved paper file fastener are made of heav paper stock such as fiberboard, cardboard or the like and comprise a base I including a bod portion 2 having spaced narrow flat elongated tongues 3 and 3' formed integrally thereon and capable of being readily bent at right angles amended April 30, 1928; 370 O. G. 757) 2 to the body so as to pass through perforations 4 in the paper file 5. The novel feature of the present invention resides in the pressure plate 6 having spaced pairs of slots I, I and 8, 8' providing keeper or locking means 9 and 9' as an integral part thereof, with the pressure plate 6 being perforated at each end to provide apertures I0 and I0" which are adapted to receive the tongues 3 and '3' respectively on the base I. The'flexible, non-metallic paper body portion 2 including the tongues 3 and 3 of the base I and the pressure plate 6 of the file fastener may be reinforced b gluing a fabric material to the faces thereof, with the compressor plate 6 being preferably less flexible than the body 2 and tongues 3 and 3"of the base I. Each pair of slots 1, I and 8, 8 are formed adjacent to the middle of compressor plate 6, whereby keeper means are provided a predetermined distance from each of the apertures I0 and Iiif at the ends of the plate. The portions of the plate 6 between slots I, 'I and 8, 8 provide transversely extending bars I I and II re s'pectively,'which are raised for permitting the tongues 3 and 3 to be threaded thereunder.
The compressor plate '6 is stamped out of,
fiberboard or ther similar material in one operation, which results in the plate having the apertures Ii! and Iiiand the pairs of slots 7, I and t, 8 or a total of two apertures and four slots, with the pairs of slots I, 'I and 8, 8 and the raised keeper bars I I and I I therebetween providing keeper means 9 and '9' for holding the tongues 3 and 3' in a manner to be hereinafter described.
When applying the device comprising the present invention, the base I of the file fastener is laid out flat, with the tongues 3 and 3' bent upwardly at right angles thereto. The file of papers 5 which have previously been punched at proper intervals forming the perforation 4 to receive the tongues 3 and 3' is then placed on the base I, thereupon the compressor plate 6 is placed on top of the file, with the tongues 3 and 3' extending through the apertures I0 and It! in the ends of the compressor plate. The tongue 3 is then bent over to the right by pressing it fiat against the portion of the pressure plate between the aperture IE3 and slot 1 thereof, with the tongue 3 facing away from the center of the compressor plate, and the end is then passed through the slot i of keeper 9, thence under the raised keeper bar II to the slot I, through which it is fed upwardly. The free end of tongue 3 is then bent back upon itself over to the left I2 a 3 and fed downwardly through the aperture Ill, thence under the left end of the plate from where it extends, lying fiat against the upper surface of the paper file 5. The free end of the tongue 3 is then bent over to the right by pressing it flat against the upper surface portion of the pressure plate 6 between the aperture 50 and the slot 8 of keeper 9, thence under the raised keeper bar I I thereof to the slot 8 through which it is fed slightly upwardly. In order to secure the file fastener, the tongues are pulled tight in opposite directions until the file is bound tightly. The free end of tongue 3' is then bent back upon itself over t the right at I2 and fed downwardly through the aperture l, thence under the right end of the plate from where it extends, lying flat against the upper surface of the paper file 5.
As-a result of this operation the tongues 3 and 3' will extend in opposed relation to each other L toward the ends of the compressor plate from keepers 9 and 9' and in loose relation thereto. To secure the file fastener, the loose ends of the tongues 3, 3', are pulled tight before the tongues are bent back upon themselves over the bars II, I I until the paper file is bound tightly.
It is apparent from the foregoing description and Fig. 3 of the drawings that the tongues 3 and 3 are each firmly gripped by certain of the elclges of slots I, I and 8, 8 of the keepers 9 and 9' respectively, together with the gripping action of the raised keeper bars II and H between the slots as they are pressed downwardly by drawing the tongues taut and by bending the tongues back upon themselves, with the ends of the tongues again passing back through the apertures l0 and Ill and extending under the ends of the pressure plate 6. In this manner the file fastener binds the papers together tightly and is not easily separated.
It will thus be seen that there is provided a novel and efficient form of file fastener which is well adapted for the purpose intended. Even though there has herein been shown and described certain features of construction and operation of parts, it is nevertheless to be understood that various changes can be made therein if the changes do not depart from the spirit or scope of the claims.
Having thus described my invention, what I claim as new and wish to secure by Letters Patent 1. A paper file fastener assembly comprising,
in combination, a base member provided with spaced terminal tongues, and a compressor plate cooperating with the base member and provided with apertures adjacent to its ends arranged to receive the tongues, and having a plurality of pairs of longitudinally aligned openings located on either side of the transverse center line of the compressor plate, and keeper bars formed integrally with the compressor plate and raised above the surface thereof, the keeper bars bridging the plate between the pairs of aligned openings, the tongues projecting through the said openings beneath the keeper bars and bent back upon themselves over the keeper bars and projected through the end apertures in the compressor plate.
2. A paper file fastener assembly comprising, in combination, a base member provided with spaced terminal tongues, and a compressor plate cooperating with the said base member and provided with end apertures extending transversely of the plate and in spaced parallel relation with respect to each other, pairs of transversely extending, parallel and adjacently spaced slots located in'the compressor plate on either side of the transverse center line thereof and intermediate the end apertures, and keeper bars formedintegrally with thecompressor plate and raised above the surface thereof, the keeper barS bridging the plate between the adjacently spaced slots of each pair thereof, the said tongues on the fastener bar being threaded through the slots beneath the keeper bars and bent back upon themselves above the keeper bars and projected backwardly through the end apertures in the compressor plate.
