LOOSE-LEAF BINDER? To all whom it may concern If 11 Be it known that I, ADOL'1 'LWISSLER, a citizen of the United States, residing at St. Louis, Missouri, have invented a "certain new and useful Improvement inLoose-Leaf Binders, of which the following is a full, clear, and exact description, such as will enable othersskilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a perspective view of onelform of a base or back plate to Whichmy' improved binder is applied.

My invention relates to loose leaf binders of the type wherein a pair of curved arms or hooks are utilized to form a ring or loop, and which ring or loop engages through openings suitably formed in the loose leaf sheets or cards.

The principal obj ects of my invention are,

first; to provide simple andinexpensive' devices composed of few parts, which can be readily assembled and adjusted, to receive and bind different sized sheets or cards, or sheets or cards having the binding holes or apertures located at different distances apart; second, to provide back plates upon Specification of Letterslate nt Patented Sept. 29, 1914. Application filed March 27,1911." Serial No. 617,148. I

- which the binding loops or rings can be adjus'tablyseated; and third, to fulcrum or pivot theTarms or hooks forming the rings or loops of the binder upon base plates, so that theinherent resiliency of the metal forming 'saidarms or hooks and base plate is utilized for exerting a spring like move ment to throw the arms or hooks open and closed, and for maintaining said arms orhooks in both closed and open positions, thereby doing away with the springs usually employed in connection with devices of the character-to whichflmy invention pertains.

To the above purposes my invention consists in certain features of novelty hereinafter more fully described and claimed.

Inthe construction of my improved loose leaf binder as illustrated in Figs. 1,3, 4:

and 5,1 designates a center back or base plate which is particularly designed to receive the binders hereinafter described and which metalback or base' 'plate is applied to the holder for the loose leaf sheets or cards, which holder is, usually composed, of a pair of heavy card board or metal covers joined by a flexible. section'such as clothor leather. The platel is provided adjacent each endwith a row of U-shaped slits 2,

and the material within said slits when bent upward forms tongues 3, which are adaptedto be bent over the ends of the binder baseplates applied to the back 1, and by forming a member of these slits 2, aseries of tongues are formed, whereby the binder base plates can be selectively located at different" points on said back 1. The back plate 1 is also provided adjacent each end "with rows of perforations 2* adapted to receive rivets or like fastening devices, utilized for fixing the base plates of the binders to said back. l designates the binder base plate, which is preferably formed of. thin sheetmetal, the centralportion of which is stamped or pressed upward to form an inverted U-shaped rib 5, the central portion of which is cut awayas designated by 6,.and the upper outer corners of said rib being cut away as 'desigriatedby 7. When thebase plates 4: are located onthe plate 1, they are secured thereto by bending up a pair of the lips 3 so as to engage over the ends of the plate 4:, or by means of. rivets which pass through suitable apertures in said base plate and throughthe apertures 2 When it is desired to change the position of either one or both ofthe base plates, this can be readily 'these inwardly bent lower ends are notched as designated by 9 to form bearings which are fulcrnmed or bear upon transversely disposed pins 10, the, ends of which are seated in theside'walls of the inverted U-shaped rib 5. The end of the inwardly bent lower portion of one of the arms or nooks 8 is provided with a transversely disposed shaped or knife edged bearing 12, and the corresponding end of the opposite inwardly bent lower portion is provided with a concave face 13, against 'whlch the knife edged bearing engages, and when the loop formed by the arms or hooks 8 is closed, as shown by solid lines in Fig. 3, the bearing point of the knife edge 12 against thecorresponding concave face 13 occupies a point just below the horizontal plane occupied by the fulcrum or pivot points of the arms on the pins .10. The inherent resiliency of the metal forming the base plate 4: and in the metal forming the lower portions of the walls of-the inverted U-gshaped rib 5 which resiliency is materially increased by reason of the transverse slot6 in said rib 5, resists the outward pressure of the inwardly bent lower portions of said arms or hooks 8 upon the pins 10 as said armsor hooks are swung toward; and away from one another, and thus asthe bearing-point between the edge 12' and face 13 passes above andbelow a center line. the arms or hooks 8 will be thrown open and closed with a spring like motion, and said arms .or hooks will be firmly held in both open and closed positions. "When the arms or hooks are swung apart into open position the inner ends of the inwardly bent lower portions bear against the upper portions of the rib 5, immediately adjacent the transverse slot 6, and thus'the opening movement of said arms or hooks is limited, see dotted lines Fig. 3.

structed of a strip of thin metal, the side edgesof which are bent upward and inward In the form of the device illustrated in Figs. 2, 6 7 and 8, the back plate 1 is .con-

to form continnous'retaining lips 14 and formed in the top faces of this strip and extending the entire length thereof is a series of transversely disposed shallow teeth or corrugations 15. In this form of the device a thin metal plate16 forms the baseplate of the binder loop, said plate being of such size as to fit on top of the base with ,its

'cates with the transverse slot 18.

side edges beneath the lips 14. The central portion of the plate 16 is stamped or pressed upward to form an inverted U-shaped rib 17, the central portion of which is slotted transversely as designated by 18, and the outer upper corners of said rib being cut away as designated by 19. An opening 20 is formed through the plate 16 at the center of the rib l7, and which opening con'nnuni- The binder loop or ring in this form of the device comprises a pair of mating curved arms 21, the lower ends of which are notched as designated by 22 to form bearings which receive pivot pins 23, the ends of which are seated in the side walls of the inverted U- shaped rib 17. The meeting lower ends of the arms 21 are provided with transversely disposed semi-circular bearin gs 2-1, and journaled therein is a pin 25, the ends of which are provided with small disks 26. The

arms 21 just described fulcrum upon the pins 23 during the opening and closing movement, and the pin 2=1 ournaled between the lower ends of said arms 21 moves above and below the plane occupied by the centers open and closed positions. YVhen the arms .21 are closed, as shown in Figs. 7 and S, the' transverse pin 25 is in its lowermost position, and the disks 26 on the edges thereof engage in a pair of the grooves between the teeth or corrugations 15 on the plate 1, and therefore, the base plate 16, which carries the arms 21 is locked or anchored to said back or base plate 1. When the upper parts of the arms are swung apart to open the loop, the pin 25 is. carried upward a short distance, thereby drawing the disks 26 upward away from the corrugations or teeth 15, and the base plate 16 can now be moved lengthwise and adjusted to the desired position on the back or base plate 1.

In Fig. 16 the base plate is shown provided with a row of openings 15 adapted to receive the disks 26 when theloops or arms 21 are closed, and which openin are of any desired shape.

It will be readily understood that two or more loops composedott' the

arms

8 or 21 are used in connection with the backs or base plates 1 and 1*.

In the modified form of the device seen in Fig. 9, the lower ends of the arms 27 forming the binding loop are notched and fulcrumed on a pair of pins 28, which are placed comparatively close to one another, and close to the transverse slot in the center of the base plate, and in this form of the device ears 29 are bentlaterally from the ends of the housing or rib formed on the center of the base plate to form stops to limit the outward swing or opening move ment of said arms 27. i i i In the form of the device shown Fig. 10 the lower ends of'the arms 30 forming the loop are journaled upon pins as herein before described,and positioned between the lower ends of said arms 30 is a small transversely disposed roller 81, which forms a bearing between said lower ends, and said roller moves over and MElO'W the plane occupied by the centers of the pivotpins as the arms 30 are opened or closed. v

The back plate which. is particularly designed to receive the form of'the device shown in Fig. 10 is illustrated in Fig. 15 and said back plate comprises a body portion 80 in which is formed a longitudi nally disposed slot 30", and the edges of said slot are notched as designated by 30% When the binding devices of the type shown in Fig. 10 are applied to the back plate 30 and arms forming said binding devices are closed the lower ends of said arms engage in an opposite pairof the notches 80,thus locking said devices to the plate 30. When the arms are swung open the lower ends thereof are disengaged from the notches 30 and thus the binding devices are .adjustably positioned on the back plate 30.

In the form of device seen in Fig. 11, the

lower ends of the arms 32 forming the loops are notched in their-outer faces, and seated in these notches are the upper ends of ears 33, bent upward from the base plate, thus forming fulcrums for said arms 32. In this construction a pin 3-1 is mounted between the lower ends of the arms 33, and the ends of said pin 34 is provided with disks which where the rib is provided with only one slot.

In Fig. 18 the arms 88 forming the loop are pivotally mounted attheir lower ends on pins 39, and the lower end of one ofthe k arms is provided with a knife edge bearing whlch engages, a concave face formedon the corresponding end of the opposite arm.

In the form of the device shown in Fig.

14 the transverse rib on the base. plate is done away with and the lower ends of the arms forming the loop are pivotally mounted on pins 40, the ends of which are seated in ears l1, projecting upwardly from and; preferably formed integral with the base plate. i 1

.Looseleaf bindersfof my improved construction are comparatively simple, can be cheaply manufactured are easily and quickly adjusted soas to accommodate" different sized sheets of paper or cards, and the base plates carrying the binding loopsf can be readily locked to or released from the back plates with the same motion required for (opening and closing the loops and the hindingloops of thedevicecan be easilyopened or closed by merely exerting a pull or pressure upon thearms themselves and without the manipulation of any auxiliary springs or looking devices. All of the binding loops on the baseplate can be opened simultaneously by merely swinging the covers of the binder back, and exerting suflicient pressure on the leayesor cardsto swing the upper portions of the loops apart. The adjust- ;ability of the'binding loops upon the metal back platesisfa verydesirable feature for :looseleaf binders, inasmuch as the binding loops can be easily and quickly shifted toward and away from one another to suit and accommodate the perforations formed in the sheets or cards tob'e bound. 7

The binding loops are constructed so as to be interchangeable and can be applied to i all forms of back plates,and if desiredthe base ,plates can be fastened to the back jplatespermanentl by riveting'or turningup the tongues formed on the back plate. By this improved construction the loops and back plates can be packed separately in compact form, andsuch construction permits booksto be rnade up with the back plates attached thereto, a11d said' books can. be

packed fiat "so as to occupy comparatively little space.

It will be readily understood that minor changes in the form and size of the various parts of my improved device may be made andsubstituted for those herein shown and described without departing from the spirit of my invention, the scope of which isSel "forth in the appended claims.
