ARTHUR TAIT, OF WINNIPEG, MANITOBA, CANADA, ASSIGNOR TO THE BUSINESS SYSTEMS LIMITED, -OF TORONTO, CANADA, A CORPORATION OF CANADA.
LOOSE-LEAF BINDER.
To all whom it may concern:
Be it known that I, Aarnun A. TArr, of the cit of Winnipeg, in the Province of Manito a, Canada, have invented certain new and useful Ir'nirovements in Loose- Leaf Binders; and I hereby declare that the follo, is a full, clear, and exact description of t e same.
This invention relates to a loose leaf binder comprising a bottom board, two
ts connected thereto, a top board adjustable on said posts relatively to the bottom board, and a spring actuated lock carried by-the'top board and arranged to engagesaid posts and revent the outward movementof the top oard until said lock' is released, as hereinafter described land particularl set forth in the appended claims. For al understanding of the invention reference is to be had to the following del scription and to the accompanying drawings in which,
. Figure 1 is a perspective view of the loose leaf inder showing the general. construction and arrangement of the arts. sectional view showing t c locking bar in engagement with one of the posts. Fi 3 is a similar view to ',Fig. 2 with the loc ing bar released from the post. Fig. 4 is a perspective view of the locking bar. Fig 5 is a perspective view of the lock case. ig. 6 is a rspective view of the actuating spring lfor t e locki bar. Fig. -7 is a perspective view of the f crurn for the locking bar, and Fig. 8 is a cross sectional view of one of the t8. Like characters of reference refer to like parts throughout the specification and drawnrojecting from the inner surface of the bottom board a are .two sts b located adacent to the one edge c ereof. The posts may be angular or multilateral in cross section, but it. is preferable to make them triangular in cross section with the apex of each triangle pointing inwardly.
Op ser. boar 'd having apertures s for and preferably of the same sha e as the posts lg so that the top board can e adjusted relatively to the bottom board a. and guided in its adjusting movements by the posts. Attached to the outer surface of the top hoard fl is a met-al plate s'tifi'ened by a dinally disposed ri- Fig.' 2 is a' to the bottom board u. is a top Patented Dec. 3, 1907.
the metal plate]r are apertures f1 corresponding to the apertures e. Connected to or forming part of the metal plate f is a lock case t uielosiug the apertures h. The lock euse t consists ol' side walls y' and end walls [t and k. At the top of the end walls k ars inwardly extending flanges Z having aperture sections m corresponding to the shape of the a-l'acent parts of the posts b and alined `witli the corrcsj'ionding parts of the apertures h.. Contained within the loc-lc case-s are lockm bars o having down turned flanges p of su istantially triangular shape, and extending through the lian es p and through the su e walls? of the lo( t cases are fulcrum )ins fupon W lich the locking bars o osciliate. he ends of the locking bars o adjacent. to the posts b have aperture sections r corresponding m sha e to the adjacent parts of the posts. r en the locking bars o are in posilion in the lock casesi, t e aperture sections r form with the aperture sections m, apertures corresponding in shape to the shape of the posts b, and the apertures so formed b the aperture sections 1' and 'm are alined wit i the apertures c and h. The ends o of the locking bars o opposite the aperture sections r project beyond' the flanges p and are slightly upturned to constitute thumb, pieces for the actuation of the locking bars. As shown in Figs. 2, 3 and 4, of the drawings, the dimensions of the lockirg bars o are sliphtly less than the inner dimensions of the loc cases t, so that the locking bars o can freely operate therein, as hereinafter described.
Coiled on the fulerurn pins q are springs s having' arms t and t', which engage res ectively the bottom of the lock cases t am the under surfaces of the locking bals o, As shown in Figs. 2, 3 and 4 ol: the drawings, the fulcrum pins q extend through the flanges p adjacent to the thunil: )ieces o', but between the thumb ieccs and tl v In manu acturing the binder, the top and bottom boards are made of the same shape and dimensions, and the metal platefwith the lock euses t' are secured to the outer surface of the top board. The posts b are connected .to the inner 'surface of the bottom board so as to extend through the alined spi ell-uros 'r iu the top board und 7.'. in the metal ongitui plato aud the aperture sections'm and rin the i g and formed through l top of the lock. eases and lof-king bars.
1e aperture. sections r. 100
' In assembling tbe parts, the posts b are in- -sorted through the apertures e and "h, and
' on the when they come into contact with the locking bars they displace the lat ter as the top board moves on the sts towards the bot# tom board the locking bars moving outwardly in the direction indicated b arrow in Fig. 3, to permit the top board sli i freely posts in the direction of the ottom board. When the top board contacts the inner surface of the bottom board or the a"dj'acent surface of the leaves its movement towards the bottom board is arrested and its outward movement is prevented by the engagement of the locking bars einstl the posts. The llocking bars are held in en agement with the posts by the action o the s which press 'the thumb pieces o outand the aperture'd ends of the locking bars inwardly to enable the apertured ends to bind against the'posts during the outward movement or attem ted outward movement of the top board. o releasethe locking bars from their en agement with -the posts, pressure isappliet to the thumb pieces o in the direction indicated by arrow 1n Fig. 2 to de ress the thumb pieces into the. lock cases. e depression ofthe thumb ieces into the lockfcases movesl the locking ars from the osition shown in" F' 2, to that shown in 3, and when the ocking bars are in the position shown in Fig. 3, the top board d can e freely moved outwards on the poets b and removed therefrom if necessary. When the pressure is removed from the thumb pieces o', the actuating springs amove the locking bars from the plosition shown in Fig. 3, to that shown in 'g. 2 to cause the apertured ends of the locking bars to eng e with the posts b. As shown in Fig. 2 the oeking bars o when in engagement with the posts b incline slightly above the top surfaces of the lock cases i and the le h of the locking bars o from their places o contact with the posts b' to the center ofthe' fulcrum ins q is greater than the length of a line parallel with the top surfaces of the Aloclt-cases drawn from the centers of the fulcrum pins to the adjacent surfaces of the posts, so that the outward pressure of the top board will be resisted by a force equal to the strength of the parts.
Ha 'thus fully described my invention what I c aim as new and desire 'to secure by Letters Patent is:
1. A binder for loose leaves comprising, a
nasss bottom lboard, multilateral oats projectinf from the inner surface of the ottom board .j top board having apertures therein to rv' ceive the'iosts, e. plate secured to the ome surface o the top board, having aperture:- therein alined with the a ertures in the top board, lock cases secure to the plate eet-li having upri'ght sides and ends and a post engaginprojection having its inner` edge alined with t e correspondin edge of the apertune lookin bars containe between the sides of the loc cases having their outer ends to h.- depressed within the lock cases and their in ner ends to eng e. the sides of the osts an:l cooperate with t e projections on tie mds o the lock cases to prevent thc outward mowment of the cover, flanges extending down wardly from the lookin bars, fulcrum pir. inserted through the si( es of thelock mms and flanges between the ends thereof, am
springs mounted on the fulcrum pins to en- 'gage the bottom of the lock cases and the on der surfaces of the locking bars adjacent t i the outer ends thereof.
2. A hinder for loose leaves comprising. i: botto1n`board, multilateral osts projcciinz,4 from the inner surface of the bottom bom-d. top board having apertures therein to recel x v the iosts, a )late secured to the outer surfen1 Iof the top alined with the a ertures in the to board., lock eases securet to the plate, eac havin- 1; upright sides and ends and a post en aging projection having its inner edge ,alin u iii. thc corresponding edge of the aperture, l wkllngbars contained between the sides of the bock cases having their outer ends to be depressed within the lock cases and their inner ends to engage the sides of the posts and coerste with the projections on the ends of t e lock cases to prevent the outward movement of the cover, triangular guiding flanges extending downwardly from the locking bars, fulcrumpins inserted through the sides of the lock cases and the flanges between the ends thereof, and springs mounted on ,the fulcrum pins to eng e the bottom of the lock cases and 'the um er surface of the lockin v bars adjacent tothe outer ends thereof.
