ROBERT J. COPELAND, OF TORONTO, ONTARIO, CANADA BINDER.

To all ilmm it. may concern a citizen of the United States, .and a resident of Toronto, andwhose post-ollice address' is 75 Queen street west,..loronto,-Do minion of Canada, and now temporarily residing at London, England, have invented certain new and useful linprovements iii Binders, of which the following is a specification.

This invention relates to lbinders of the class adapted to confine a plurality of loose sheets by means of, two or more separable members. Two of these members serve to clamp the sheets to be bound and it is ageneral obj ect of this invention to provide means whereby one of said clamping members may be quickly and conveniently pressed by hand from open to closed position relatively to the second and then positively clamped against the bound sheets by mechanical means such as a mechanical power.

A further object is to vprovide a releasing means in combination with this mechanical power whereby azquick release of the clamping member or'ineinbers may be effected.

`More specifically, arr'object of the invention is to combine a suitable grip or clutch mechanism preferably a friction grip cooperating with an untoothed tongue with a mechanical power which is employed to move two members of the binder relatively to each other.

1n a preferred form of the invention, this grip mechanism and mechanical power are employed positively to actuate a pair of separable binding strips. 1t is preferred that these binding strips be confined to move with a parallel motion and always equally separated from a third strip or back inem- 'ber. Any suitable .means may be employed to give the binder strips this parallel movement although connecting links may be preferably employed and operate as toggles iii 'combination with a reciprocating plate.

A preferred embodiment of the invention is shown in the accompanying drawings forming part of this specification and in Figure 1 is an inside elevation of the assembled binder frame with p art-s broken away and thecovers removed. Fig.` 2 is a detail section, 'eiilarged' and showing 'the mechanical power and gripping mechanism, but '\vitli"plate 3:9 renioved. Fig. 3 is a devtail section through line 3 3 lof Fig. 1 'show- Specification of Letters Patent.

A "ing the key seal case. Fig. 4 is atleta-il view Be it known that 1, ROBERT J. COPELAND,

taken lthrcnigh line lill of Figfl, with parts omitted. F ig. 5 is a perspective view of the tail section'through line (3i-6 of Fig.v 2 but showing the reciprocating slide in position. F 7 is an enlarged detail section showing the constrictor 22.

referring now more in det-ail to the drawings,-1 and 2 indicate respectively' upper and lowerseparable members or separable binder strips mounted to slide, in opening and closing, upon a back plate or member 3. The clamps 4 land 5 are secured lto the back plate and serve to, hold the strips land 2 against the same, while guiding the strips in their opening and closing movement. addition to this guiding means, there are provided a series of telescopic lposts 6, 7 of any desired number. These posts have one member 6 or 7 secured to a strip 1 or 2 and also serve to steady the opening and closing of the binder strips andarev provided for filing perforated paper sheets. Some spring means is preferably provided normally tending to separate the binder strips. As illusin certain of the post-s 6, 7, preferably in the outside pests. More springs 8 may be provided in a similar manner, if desired, or spring means for opening the binder may be provided in other localities than in the posts.

10 designates a longitudinally reciprocating member or slide constrained against transverse movement relatively to vthe back 3. Pivoted to this reciprocating member at their inner ends' are a series of links 11, 12, 13 and 14. The other endsv of these links are pivoted, 11 and 13 to the upper binder strip 1, and 12 and 14. to the lower binder strip 2.

A trough 13 is formed medially along'the inner face of the back member 3 for the reception of the mechanical power and gripping means. Fixed against `longitudinal movement in a bearing 16 is a mechanical power in the form of a screw 17. The threaded sleeve 18 operatively engages tl'ie screw 17 and has secured thereto a tubular shell 19 by means of a pin 20. This pin 20v extends through both the shell 19 and sleeve 18 and projects into agroove 21 formed longitudinally in the bottom of the trough 13,- thus permitting a longitudinal movement of tation thereof. The inner face of the outer end of thes'hell 19 isl restricted and .prefer- :gripk aw member..` Fig. Gis anfenlarged de-v the shell 19 and sleeve 18 but preventing rotrated, this spring means 8 may be located gether by en agement with t ably formed conically, as shown at 22, so as to rovide a constrictor or closing means against which the gripping yjaws 23 are normally pressed by the spring 24. As best seen in Fig. the jaws 23 are formed of segments, preferabl conical, and having spring Shanks 25, whic ferentially continuous portion 26 of the shank. The jaws 23 have a normal tendency to Vremain slightly spread apart, as illustrated in Fig. 5, but ma be forced tofie conical face 22 of the Shel 19 so as to rip a cooperating tongue 27, which is pre -erably'rearwardly tapered, as shown, so as to increase the gripping action of the jawsy 23. The tongue 27 extends longitudinally from the block 28 which is secured directly to the 'reciprocating member or slide by means of a screw 29.

30 is an abutment fixed fast to the walls of the trough 13 to coperate with the gripping aws 23, as will hereinafter be described, and also lcenterin the tongue 27 which passes therethroug The exposed end of the screw 17 is provided with an extension 31 specially formed for the reception and engagement of the key 32.V This extension 31 Ina besquared or otherwise formed for loc ing engagement with said key. A suitable hole 33 is formed at the end 34 of the binder backthrough plat'e39 to permit the insertion of the key 32.

As shown in detail inFigs. 2 and 3, the end-34 of the back 3 instead of being solid like the` opposite end 35, may be cut away at 36 for the reception. of a-case 37 which is hinged at 38 to an outer plate 39 secured to .the end 34 by screws 40 and it is through this plate 39 that the hole 33 extends. The case 37 is pierced to form a hole 41 which will aline with the hole 33 when the case 37 is forced d own into the position shown in Fig. 4. A paper seal ma be inserted within the case 37 to cover the oles 33 and 41 and prevent tampering withy the binder actuating mechanism. A. spring 42 normally tends to elevate the case 37. When the binder is Closed, as shown in Figs. 1 and 4, the case 37 Y may be pressed down, as shown in Fig. 4,

when the catch 43 engages in the slot 44 to hold the case closed as shown in Fig. 4. Although the spring 45 normally tends to force the case 37 away from the plate 39 to disengage the groove 44 from the catch 43,

Athe inturned end 46 of' the binder strip 1 are extensions from the circumwhile thelinks 11, 12, 1 3 and 14, 'pivoted to the reciprocating member 10, always maintain the binder strips 1 and l2 at equal distances from the back member 3 and likewise maintain said strips always parallel to one another and to said back member,

lf a slight left handed movement is given to the screw 17'with the binder'mechanism as shown inFig. 1, the j aws-23 will vbe forced against the'abutment 30. The jaws 23 will be forced away from the closing means 22 against the action of the spring 24 and will spread apart due to the spring action of the Shanks 25 so aste release the tongue 27, which may then freely therebetween. Then the binder stripsji and 2 will ily apart quickly inresponse to the'action of the separating springs 8; When the jaws 23 are abutted against the abutment 30, the binder strips 1 and 2 may be manipulated manually, freely into open and closed positions. The abutment 30 is .therefore means independent of the tongue 27 for releasing or isengagmg the grip. Thus, when the ybinder is open, the

desired number of sheets to be bound may be inserted within the binder about the posts 6, 7 and the slack between the binder strips 1 and 2 and the sheets may be uickly taken up manualhr by pressing the inder strips together. t has been found, however, that theA mere manual pressing together of the strips will not alwaysfirfnly clam the bound sheets. Firm clamping of the s eets may be accomplished -with satisfaction by imparting' a righthanded movement to the screw 17, so that the jaws 23 leave the abutment 30. Then the spring 24 forces the jaws 23 against the constrictor or closing means 22 which wedges them together so as to grip the tongue 27.

24 is means for rendering the constrictor operative to cause the grip to grip the tongue. A continued movement of Ithe screw 17 to the right will cause the grip 23. to drag along the tongue and the resistance of the tongue to this dragging along will cause the grip 23 to grip it the tighter by increasing the wedging action of the closing means 22 on the grip 23. This gripping is increased by the wedging action o the tongue 27 when it is tapered as shown. As the tongue 27 is dragged to the right, it lcarries with it the block 28 and the reciprocating member 10 secured thereto'by a screw 29. ber 10 exerts a positive mechanical clamping action u on the binder strips 1 and 2 bv means o the links 11, 12, 13 and 14, which action is, of course, in addition to and separate from any clamping action which may be manually exerted directly upon the strips 1 and 2. lt is'also obvious that, even when the gripping jaws 2? are clear of the abutment 30 and are pressed into engagement with the tongue 27, that the tongue 27 has a This memerases right, independent ot the mechanical movement or screw 1T, and the untoothed tonguey tend to torce them back to thel right against the action ol spring 2-1. Any slight movement o'il the jaws 23S to the right relative to the constrictor or closing means 22 will relieve the closing action oi 22 and the jaws will open sulliciently to allow the tongue 2T to slip therebetween 'freely to the right but they would ellectively check any return movement ot' the tongue 27 to the lei't. Thus, even when the position ot the grip is such that the binder strips l and 2 are not permitted to be moved freely into bothopen and closed positions independently ol' the mechanici'il clamping means l?, 1,3, ctc., they do have a Ylrce movement into closed position which may be accomplished manually because ol the Al'ree movement ol tongue 27 in a right liand diiection, as just described. Ot course, il desired, the strips may be closed together entirely by the action oi `the screw means l? ete. without being manually closed but this takes more time. f
