To all whom t may concern."-

Be it known that I, AUGUsT J. KonrsnLL, a citizen of the United States, residin at Mayville7 in the county of Dodge and tate of Wisconsin, have invented certain new and useful Improvements in Loose-Leaf Binders, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to binders for loose leaves, and particularly to those binders in which the loose leaves are engaged by rings.

Loose leaf binders are made up in a large variety of styles and the rings are disposed different distances apart and as a consequence the leaves which are punched to suit one binder or one set of rings will not fit notebooks or the like having rings arranged for other punchings. As a consequence, it is necessary to secure paper-'which is punched in a certain manner for any particular binder and this is sometimes dillicult to achieve. Loose leaf notebooks are used in schools to a very'large extent to-day and this difficulty in readily securing paper which has been punched to lit any particular type of binder is a veXation.

The object of this invention is to provide a binding device of this character in which the rings for engaging the paper are adjustable toward or from each other so that any paper may be used with any particular binder, thus doing away with the necessity Vof carrying many different types of cut leaves punched to suit many different styles of binders. y

A further object is to provide a device of this character in which the rings are adjustable toward or from each other and in which the rings may be held in their adjusted positions. Y

A still further object is to provide abinder in which the spaces between the ends of the ,split rings may be close-d by merely turning an operating shaft which will act to close all of the rings or open all of the rings.

Another object is to provide a device of this character which may be adapted to carry any number of rings, which is relatively simple, rnay be cheaply made, and which will be thoroughly effective in actual practice.

Other objects will appear in the course of the following description.

My invention is illustrated in the accornpanying drawings, wherein Figure l is a top plan view of my device applied to the cover of a notebook;

Figure 2 is a longitudinal sectional view through the back of the notebook and my mechanism Figure 3 is a section on the line 3--3 of Figure 2 with thenotebook cover omitted;

Figure 4l is a perspective view of the upper plate;

Figure 5 is a perspective view of the lower plate;

Figure 6 is a section on the line 6 6 of Figure l; Y

Figure 7 is a section on the line 7 7 of Figure 1. r

Referring to these drawings, 10 designates a base plate which is relatively long and relatively narrow and has apertures at its ends whereby rivets 11 may be used to attach the base plate to the cover 12 of the book. This base plate 10 is provided on opposite edges with the upwardly extending flanges 13. This base plate 10 is made of thin sheet metal. Y

Resting upon the base plate 10 is a .longitudinally extending upper plate 14 which for the greater portion of its length is narrower than the plate 13 but at its middle has a width approximately equal to that of the strip or base plate 10 as at 15. which enlarged portion 15 is formed with the downwardly extending flanges 16 which are adapted to lit inside of the flanges 13. This enlarged portion 15 is formed with a centrally disposedn unstanding screw 17, and on each side of this screw with rectangular' apertures 18. The extremities of the plate 14. are also enlarged at 19. This portion at its end is downwardly turned and then lon- `gitudinally extended at 2() to form a foot riveted to the strip 10 by the rivets 11. The portions 19 are closed at their sides by flanges 2l. and the downwardly extending wall 22 is apcrtured at 23 to forni a bearing.

Disposed to rest upon the base plate T10 are a plurality of slides 24. each slide having a width' approximately equal to the distance between the flanges 16 and being guided by these flanges and having a longitudinally extending shank 25 which is offset with relation to the center line of the corresponding slide 24. Certain of these slides Ell v otherwise.

l ing plate 27 which rests upon the upper face of the portion'l of plate 14 and which has downward projectionsA 28 which pass through the apertures 18 and which rest upon the Shanks 25. This plate 27 is apertured at its center to receive the upstanding screw 17 and a nut 29 engages this screwthreaded post or bolt and, of course, bears upon the binding plate 27. Thus as the nut is turned down, the projections 28 will bear against the Shanks 25 and lock these Shanks against longitudinal shifting movementbetween the flanges 13 and with relation to each other. When theset nut 29 is turned off, however, it is obvious that these slides 24 may be shifted by hand to any desired i v position and then again locked.

Each of the tubular rings 26 has a gap in its upper portion and disposed within'each' tubularring is a slidable section 30, arcuate in form, housed within the ring and adapted, when shifted. in one direction, to close the gap between the ends of the ring and form .a continuation thereof and, when shifted in the other direction, to open this gap. This permits the insertion of the paper in the ring, and the` closing of the ring through the perforation in the paper.

For the purpose of operating all of these members 30 simultaneously, I mount in the vapertures 23 the operating shaft 31, this shaft having reduced portions 32 which fit in the bearings23.. Between thesereduced portions the shaft is provided with a longitudinally extended'eylindrical toothed gear 33. The inner faces of the rings 26 are cut away at 34 and this toothed portion 33'ts in this cut-away portion 34 and engages with teeth 35 formed upon each member 30. Therefore, it is obvious that as the shaft 3l Vis rotated in one direction the members 30 will be Drojected to close the gap in all of the rings and upon the rotationV of the shaft 31 in the opposite direction the members'30 will be retracted to open the gap in the rings. This member 31 has a shank 36 provided with a head whereby the shaft may be rotated. Preferably this head 37 is pivoted at 38 to the shaft so that the head maybe turned into a position at right' angles to the Ashaft or into alignment with the shaft.

This head or handle Yis to be thrown back into angular relation to the shaft when not in use. The elongated teeth 33 will obviythere' are three slides on each end of the'device, will come beneath and be bound by the projections 28 of the binding plate 27. By taking hold of any particular ring, however, it is obviousthat that particular slide, provided the nut 29 has been turned olf, may,

be shifted to any desired position. Then when the nut is turned down, it is obvious that the projections 28 will bind on all three of the Shanks, or as many Shanks as there may be on one side of the device, andhold `all of the rings on that side from longitudinal movement. Then after the rings have been adjusted longitudinally so as to bring` these rings to the proper position to engage the holes punched in the note paper, the shaft may be rotatedto project all of the members 30 of the several rings so that these members will be forced through the holes in the `paper and the leaves'will be bound by' the rings. Gf course, when the handle 37 is turnerL into angular relation it bearsV against the @over of the back and t-he shaft 31 cannot be further turned until the handle is drawn out into alignment with the* shaft.

yIt will be seen that the adjustabilityrof the rings on my device does away Vwith the ne- -cessity of a stationer carrying'many different kinds'of paper just for'the purpose of being able to supply the demand for paper suited to many different kinds `of covers.

lThe device may be verysimply and cheaply made and at the same time may' be thoroughly substantial. Obviously many changes might be made in the details of construction and arrangement of parts without de arting from the spirit of the invention as de ned in the appended claims.
