CLIP FOR LEAVES OF FILING-BOOKS.

To all whom it may concern.-

Be it known that I, EDWARD CHARLES IVARD, a citizen of the United States, and a resident of Sioux Falls, Minnehaha county, and State of South Dakota, have invented certain new and useful Improvements in Clips for Leaves of Filing-Books; and I do hereby declare that the following description of my said invention, taken in connection with the accompanying sheet of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has reference to clips for leaves of filing books, and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described, and then pointed out in the claims.

It relates generally to clips for leaves of that class of filing books that have for their object the reception of sales slips, invoices, memoranda, or other papers, wherein it is an essential that said papers be removably retained in place against said leaves for instant removal therefrom.

The particular aim of my invention is the provision of a cheap and efficient double clip for the median row of clips employed in a certain filing leaf for which I have filed an application for Letters Patent of the United States in the United States Patent Office on July 5, 1912, Serial No. 707770.

In the drawings hereinbefore referred to, which serve to illustrate my said invention more fully, Figure 1 is a plan of a fragment of a leaf employing my double clip. Figs. 2, 3, and 4 are sect-ions of fragments of the same, on an enlarged scale, in lines 0 0, 1 1, and 2 2, respectively, of Fig. 1. Fig. 5 is an enlarged plan of the flat blank of a sheet metal binder by means of which my clips are retained in contact with the leaf. Fig. 6 is an end view of said binder after the first operation in bending said blank to shape. Fig. 7 is a similar view of the same after the second forming operation, and, Fig. 8 a like elevation after the third and final forming operation. Fig. 9 is a plan of the binder as completed, and Fig. 10 a side View of the same.

Like parts in all figures of the drawing are indicated by corresponding characters or symbols of reference.

Specification of Letters Patent.

Application filed September 30, 1912.

Patented Aug. 5,1913. Serial No. 723,142.

In the production of leaves for filing books, it is a great desideratum to maintain the leaves with their retaining clips as thin as possible, so that a book containing a large number of leaves will not be so bulky as to prevent its insertion into the average merchants safe compartment. The clips employed in connection with these leaves must be tensioned so as to maintain a constant pressure against the face of the leaf, and this is usually accomplished by forming a series of helical coils, normally in torque, near the free ends of the clips to produce the necessary pressure. Since these clips are fastened to both sides of the leaf, the employment of helical coils imparts an objectionable thickness to the leaves and oftentimes defeats the sale of the article.

To avoid the above objections I produce my double clip from a single length of wire bent into proper shape, with a series of runs, constantly in torque, arranged parallel to each other and held together by a light sheet metal binder, which binder has projections extending through slots or punctures in the leaf to the reverse side thereof, where the projections pass through a similar binder for the clips on that side of the leaf and are there clenched over, thereby retaining the clips on both faces of the leaf in proper position in an effective manner which is both cheap and efficient.

For a better understanding of my invention, I now refer to the drawings in which A is a fragment of the filing leaf and B B one of the double clips on the face thereof, while C is the sheet-metallic binder for the clip, and C the binder of the corresponding clip on the reverse side of the leaf.

To form the double clip B B from a single length of wire, I first produce a rightangled bend on one end of the wire to form a stub end 1. From there the wire extends horizontally in arun 2 for a suitable distance to a practically right-angled bend pointing in the same direction as stub end 1, forming leg 3 of the clip. This leg defines one of the lateral sides of the clip, and at its far end, the wire is bent back to form the free edge 40f the same, parallel to theinitial run 2. This free edge is now bent back at practically a right angle to produce the oppositelateral leg 5, the whole outline describing a clip of more or less rectangular contour. The inner end ofleg 5 is bent inwardly to make the secondhorizontal run 6. which extends parallel to and directly adjacentinitial run 2. The free end of thisrun 6. at a point a short distance intrriorly of the leg 3. is bent downwardly in a direction opposed to that of said leg 23 to produce the curviforin outline T of the portion Ii of the clip. Said outline 7 terminates in a return bend S, which bend defines the free edge of that extremity of the clip. A i'ter this the wire extends back in asimilar curvifori'n outline 9 to a point directly adjacent therun 6 at a point intrriorly oflateral leg 5 the same distance that outline 7 is interior of lateral leg 3. tiaid wire is now bent inwardly atv right angles and extends parallel to and directlyadjacent run 6 to form the third.horizontal run 10. Atits free end this run is bent downwardly at right angles, ending in a short stub end 11.

It will now be observed that by bending the wire as described above, two clips are produced in reality; one with its free end pointing upwardly and the other in the opposite direction. It will also be seen that one horizontal run (run 6) of wire medially between the extremities of the clips is common to both, and that in addition to this run there is provided one other horizontal run of wire for each of the clip portions. These runs are initially placed in torque when they are confined in the binder C and assembled on the leaf, so as to induce a downward pressure at. the free ends of the clip portions. l Vhen either of the free ends of the clip are elevated for the retention of nieinoranda or other papers, the torque created will be distributed in two horizontal runs of wire, thereby insuring longer life to the clip due to its ability to better resist loss of elasticity in the wire through fatigue of metal.

The binders C and G are produced from fiat, rectangular, thinsheet metal blanks 15, having along one of their longitudinal edges a. plurality of projecting pron 's 16 and a double row ofoblong perforations 17 and 17 for purposes hereinafter described. Blank 15 is initially placed into a suitable first operation forming die, wherein there is formed in said blank a U-shapedchannel 18 throughout its entire length and cross channels 19 and 19" extending transversely therefrom. At this same operation thepor tion 20 of the blank extending beyond dotted line 21 and theprongs 16 are bent downwardly at right angles as indicated in Fig. 6. The now semi-formed blank is then passed into a second operation forming die and theportion 20 partially closed down to form a bottom for the binder. The runs 2-, 6. and 10 of the clip are then placed in thechannel 18, with the stub end 1 resting in the cross channel 19 and the stub end 11 l in the like channel 19, and the whole placed into a closing die wherein thebottom 20 is closed down solidly upon said wire runs and ends, as clearly indicated in Figs. 2 and 3, thereby securely fastening them in place. In folding over theportion 20 and closing the same down as described, thepunctures 17 become registered with the apertures 17F 9 in an obvious manner.

In the leaf A there are provided a serles Fig. at, coinciding p in the body of the binder as illustrated in of oblongpunctures 22, in size withapertures 17 and in register with the same and withprongs 16. In assembling the clips on said leaf, theprongs 16 are entered into and passed through one row of these openings and also throughopei'iings 17 in the binder C on the reverse side of the leaf. Theprongs 16 on said hinder C are similarly passed through the other openings in the leaf and also through theapertures 17 in the binder C on the face of the leaf. The projecting portions of these prongs are then clenched over as at 25, Fig. 4, thereby firmly securing both of said binders and their clips in place on their "espective sides of the leaf. It will now be seen that this construction permits the employment of eflective spring clips, yet the thickness of the leaf is only very slightly increased, so that a large number of leaves may be bound together and yet be susceptible of being entered into the compartments of the average small merchants safe.

It should now be understood that while I have shown only one of my clips on the face of the leaf, said leaf may contain any number of clips as may be desired.

In the foregoing I have described the preferred shape of my clips, but I wish it understood that I may embody any other outline or contour that may suggest itself without departing from the spirit or scope of my invention.

Having thus fully described my invention, I claim as new and desire to secure to me by Letters Patent of the United States 1; In a filing book, a leaf, a spring clip thereon, formed from a single length of wire, having free edges at opposite extremities, a plurality of parallel runs of said wire intermediate of said free edges, a binder confining said runs, and means for afiixing said binder to said leaf.
