The present invention relates generally to a binding mechanism, and more particularly to a novel mechanism for spreading an elastic tubu lar binder for the purpose of inserting a pack of 5 perforated sheets to be secured by the binder, to_ obtain a book of sheets or pages, of the type shown and described in United States Letters Patent No. 1,970,285, dated August 14, 1934, _ granted to R. M. L. Douvry. 10 ' The binder comprises a continuous back por tion having a number of ?ngers extending from one longitudinal edge thereof, and made of a (Cl. 11,-1) into a longitudinal tubular form as shown, and which has su?icient ?exibility to permit spread-' ing' it open, and sufficient elasticity to cause it to recurl when released. It has been found that a certain type of cellulosic material'can be curled U! into this shape when heated, and after cooling retains that shape. ' Referring now to the several views of the spreading apparatus, asupporting base 4‘ sup ports a working plate 5, which, for convenience of 10 manufacture is made in two parts, a front plate 6, and a rear plate ‘I, both of which are secured material, such as celluloid, or pyroxylin, for ex to the base by suitable means, such as screws’ 8 ample, that can be curled longitudinally into a (Fig. 5). tubular form, and which has su?icient elasticity to cause it to reassume its tubular form when ever it is spread open and released. The principal object of this invention relates to ' A plurality of pins 9 are ?xed in a row on the ' rear plate 1, and arranged with suitable spacing to conform with the spacing between the ?ngers 3 on the binder l, as will be explained later.

A number of slots l4 are cut in the rear 'work- _ ferent sizes. 30 The attainment of the above and further ob- ' ing plate 1, these slots being suitably spacedrel jects of the present invention will be apparent from the following speci?cation taken in con junction with the accompanying drawings form ing a part thereof. In the drawings: ‘ Figure l is an isometric view of an elastic binder of the type mentioned above; Figure 2 is an end elevation of a machine em bodying the principles of the present invention, 40 showing the mechanism in normal, or released position; . .

Figure 4 is a sectional elevation taken along the line 4-4 of Figure 3; Figure 5 is a top view or plan of the same ma? chine; and 50 ' In each slot is disposed a ver hook IE, on the upper end of a rectangular shank I'l projecting‘above the'surface of the plate I.

Hence it is evi dent that the hooks l6 are maintained in align ment by the supporting structure [8, and are disposed in a row parallel to the row of pins 9_. By actuating the supportingstructure the hooks i5 can be moved in unison in the slots l4, toward or away from the row of pins 9. - Figure 6 is a detail of the removable spreader pin used in the machine. ative to the pins. tically extending spreader hook I5, which has a ' Like reference numerals ‘refer to like parts ' / The hook supporting structure mats/mounted on a pair of rack members 22, and secured by nuts 40, said members each comprising a rack 50 23 and extension rods 24 and 25. One of the throughout the speci?cation and drawings. Referring to Figure 1',.,the binder. l consi‘sts_ extension rods 24 is carriedin a bearing 26 in of a band or strip forming a back portion 2, and v the supporting frame; and has a threaded end, a plurality of spaced apart ?ngers 3. The binder 55 is made of suitable materialwhich can be curled which is provided with a pair of adjusting lock nuts 21. The other extension rod 25 extends 5 2 2,108,136 into a socket 28 in the supporting frame 4. A compression spring 29 is disposed on the exten sion 25 and operates to maintain the rack nor mally in the‘extreme position toward the left, as 5 shown in Figure 2. The rack member is partly supported by a second bearing 30. Meshing with the rack 23 are pinions 3|, mounted on a' through shaft 32, which is carried in bearings 33, 34 at each end respectively of 10 the supporting base 4. A crank 35 is ?xed to one end of the shaft 32 and is rotated angularly by an operating rod 36 jointed thereto. - Normally, .the apparatus is in the position shown in Figure 2, the row of hooks being near 15 and vin alignment with the row of pins. When the operating rod is actuated, preferably by a foot pedal (not shown), the pinions 3| are ro the binder l and the assembled book lifted off the pins 9. An assembled book can be disassembled in a similar manner. The book is ?rst pressed down on the pins, which must, of course, be inserted between the ?ngers as before, and between the pack of sheets 38 and the back portion‘ 2. The rod 31 is then inserted axially through the binder, under the hooks l6, and then by actuat ing the operating rod 36 as before, the ?ngers 10 are spread open, the ends of the ?ngers being thereby withdrawn from the perforations. After lifting the pack of sheets away from the hinder, the operating rod 35 is released, allowing the empty binder to recurl. The rod 3‘! is then with drawn, and the binder can ~be lifted from the pins. . . tated, (clockwise as seen in Figures 2 and 4) The locknuts 21 should be set for each size thereby ,moving the rack member 22 and thus of binder so that the motion of the mechanism 20 the supporting structure l8 with its row of hooks will be limited to'such an extent that the ?ngers l5, toward the right to the position illustrated will be spread su?iciently to permit insertion of 20 in Figure 4. The extent of this movement can the pack of sheets, but without allowing the ends be adjusted by screwing the lock nuts 27 in or‘ of the ?ngers 3 to escape from under the rod 31. out on the extension rods 24.

It is, however, to be understood that be explained. The ?rst step is illustrated in Fig the invention is not limited to the precise ma ure 2.v , The binder I ‘is laid on the working plate 1 with the back portion 2 held between the back ing plate I 0 and the row of pins 9. The pins are spaced so that they stand in spaces between ?ngers‘ 3 .of the'binder. i. ,The backing plate In 35 is set at such a distance from the pins 9 that it will hold the back portion 2 against the pins 9. With the rack 22 in the extreme left positioi as shown, each of the hooks I6 is in a space between ?ngers 3 of the binder l._ Certain of the 40 spaces between ?ngers 3 now are occupied by pins 9 while other spaces between ?ngers are occupied by hooks IS. The spacing of hooks and pins may be such that every space between ?n-' gers is occupied by either a hook 16 or a pin 9 45 but this is not essential, as the spacing can be made such that there are some unoccupied spaces between ?ngers 3. , Y , A rod or wire 31 is now insertedaxially through chine here shown, the'same being merely illus trative of the principles of the invention. ,What 30 is considered new and desired to be secured by ' Letters Patent is‘: v1.
