firram -16 Figure 3 is a top view-of my ring assembly Patented June 17, 1930 4 UNITED srerss DON D, MYERS, OF TOLEDO, OHIO LOOSE-LEAF BINDER AND METHOD C 15 MANUFACTURING THE SAME I Application filed iyrarch 14, 1928. Serial No. 261,549.

This invention relates'to a new and improved loose leaf binder and the method of manufacturing the same with particular reference to the type of loose leaf binder in 5 which split rings are used as the leaf-retaining members.

In binders of this character hithertoknown to the art the final assembly of difierent parts of the binder and particularly the final aslu sembly of the ring-carrying plates has been difficult to accomplish and the choice of stop nembers for controlling the movement of the ring-carrying plates has been limited.

The main object of my invention is to pro- 15 vide a book of'this character having ringcarrying plates of such a' design that they may be assembled into the book after all of the other mechanism of the book has been fixed in position. Another object is to pro- 2 0 vide a book in whichthe stop members for limiting the upward movement of the ringcarrying plates may be rigidly aflixed to the back plate of the book. i

Another object is'to provide a book in 2; which the ringrcarrying platesmay be assembled and from which they may be dis assembled without the necessity of assembling or disassembling any other part of the mechanism.- e

Other objects and advantagesrelate' to the size, shape and arrangement of parts as will more fully appear from the following de scription taken in connectionwith the accompanying drawings in which J Figure 1 is a perspective view partially.

My device consists. of covers -1 and -2 joined together by a concave back sec- I also provide a male ring-carrying plate -1l which carries on its inner edge a plurality of downwardly inclined'tongues -12.- and, a plurality of intermediate upwardly inclined, tongues 13--. I also provide on the inner edge of plate --11 an outwardly extending locking tongue 14. @ne end of the inner edge of plate 11-- is cut away to form a shoulder 15.' and the opposite end of plate -11. -i,is cut away to form a slot 16'with a shoulder -17- in. one

edge thereof. -Plate :11 alsocarrieswa: plurality of/apertures; ,-18 adjacent 'the inner edge thereof into which are placed male half-rings .-19-.- secured in position by riveting, as perhaps may best, beseen at -2 on Figure 6.

' Female ring carrying plate 2l' isprovided on its inner edgewith akeeper slot 22 adapted to co-act with locking tongue .14-. Plate '21-. is .cut away atIoneend of the inner edge to form ashoulder .23-e i and is provided at theother end of the inner edge with a slot 2 l and a shoulder .25

adjacent one side of slot 24l. Plate -21 is also provided with a plurality of apertures 26 for the reception of female half-rings 27 secured in place by riveting, as perhaps may best be seen at 28 in Figure 6. Male half-wings 19 and female half-rings 27e are so positioned respectively in plates 11 and 21 that when plates 11 and 21 are in the locked position the opposed halfrings -19 and 27 will register with each other. 7

V The method of assembling back plates 11 and -21 onto back plate l, as perhaps may best be seen from Figures 2 and 3, is as follows; I place member 11 w,ith its rear longitudinal edge in slot -6 of the back plate 4 and with slot 16- registered with cross-head 10-' of stop member 8, as perhaps may bestbe seen in Figure 3. In this position shoulder l 5- will be against the inner side of cross-head 10 of stop member 7 so that stop members 7' and 8 will not be in the path of vertical movement of the inner edge of plate 11 I then place the rear longitudinal edge of plate 2l in slot 5 of back a keeper slot 22.

plate -l with slot 2% of plate 21 registered with cross-head 10- of stop member 7- and with shoulder 28 ad jacent the inner side of stop member 8. I then insert the forward edge of plate 2'1 between the tongues 1212 and -1 313 of plate 11 with locking tongue l on the under surface of plate- 21 adjacent I vthen depress plates '11 and -21 against the spring action of back plate t and lockingtongue 1 t until the upper surfaces of plates -'11' and .21' are beneath the under surfaces of crossheads -10 of stop members 7 and -8 Ithen'move plat-es '11- and 21 longitudinally in relation to each other so that shoulder -1T of plate 11 will be positioned underneath cross-head -10- of i stop member 8 and shoulder 15- of plate -11' will be positioned under crosshead -10 of stop member +7 and shoulder 23,of plate 21+ will be positioned under crosshead 10 of stop member- 8; and shoulder of plate 21,'w-ill be positioned under cross-head -1(-)' of stop member 7. This movementwill bring locking-tongue 14E- intoregistration with keeper slot '22- so that it is allowed to spring upward into keeper slot 22+ to prevent any longitudinal movement of plates llan d 2l' in relation to each other.

The combined widths of plates 11 and 21 is such, with relation to back plate 4t,'that a vertical movei'nent either up- Or downward'of 3lates -11- and 21'fmay *be accomplished only by over- 7 coming the yielding resistance. offered by back member so that in either the raised or lowered position plates '-11 and 2l' will be yieldingly held in that position by back member l. The downward move ment of plates -11 and 21 is limited by back plate 4 and the upward movement of plates 11 and -21 is limited by cross-heads 1010 of stop members -7 and -8.

Male split rings 19 and female split rings 27 are so positioned in relation to plates -11 and 21 and to each other that when plates 11- and -21 are in the down position the prong 29.of male half ring 19,' shown in dotted lines on Figure 5, will enter the V-slot, not shown, on theendofhalf ring 27 to form a complete ring as may best be seen in Figure 6. l/Vhen plates 11 and 21- are in the raised position, as perhaps may best be seen from dotted lines in Figure 5, half rings 19 and 27 will be separatedfrom each otherto permit the insertion thereon of 7 leaves, not shown, as desired.

It will be understood that in the upward and downward movement of plates 11 7 1010 of stop members 7'and +8 into the position shown in Figure 3 and when in this position they may be removed from back plate 4 and from registrationwith each other.
