UNETED; STATES" JAMES BARKER, or KALAMAZOQ, MICHIGAN LOOSE-LEAF BINDEB Application filed February 16, 1328. Serial No. 254,828.
This invention relates to looseleaf' binders and more particularly to improvements in the construction thereof tending to simplify and render the same more efioient generally.
The invention contemplates an improved locking bar construction which may be economically V manufactured and quickly and easily assembled. This inven-tion also contemplates permanently attaching the lifting or transfer bars to the fly leaves as for instance by binding thelifting bar with the leaf. 7 i
The several objects, advantages and novel details of construction of this invention will be made more apparent as this description nection WVltll the accompanying drawings wherein s Figure 1 is afragmentary perspective view of a loose leaf book constructed in accordance with my invention, one of the covers being unlocked and moved to open position.
Figure 2 .is a plan View partly in section of the locking bar construction.
Figure 3 is an enlarged fragmentary View of a portion of the structure illustrated in Figure 2 with the parts in dii'lerent position. 4 i
Figureil is a; detail sectional view taken substantially on the plane indicated by line 4% in Figure 2, and
Figure 5 is a fragmentary PtZiTSPQCtlVB view of the'locking bar mechanism removed from the guide.
Byreference to Figure 1 it will be noted that there is illustrated a loose leaf book comprising a back 10 connecting cover members 11. T 1e reference characters and 13 indicate lifting or transrer bars. in accordance l with the usual practic'c 'each transfer bar is provided with one orinore impaling posts 1% Which project through openings in the sheets 15, the posts on one bar being out of alignment With the posts on the other bar.
It Will be noted that these transfer bars 12 and 13 are separate from the back 10 and covers 11 and in the present instance these transfer bars are secured to the respective fly leaves 16 by being bound therewith as indi- The reference character 18 inproceeds especially ivhenconsidered in con-j struck-up ears 21' providing a-guide-Way having a locking bar.22.' The one end of this locking bar extends beyond the guide vvay 23 l and is bent at an angle to-provide a thumbpieceor handle bymeans of which locking 22 is movedlongitudinally of itsguide way. i i i V s The reference character 25 indicates locking pins adapted for engagement in the socks ets 18'1" rmedin the ends of locking posts 18 When-moved across openings 26' formed in the guide way 23. In their inoperative position these locking pins are Withdrawn to a point Within the guide Way as indicated inv Figure 9 U- means of securing the looking pins 25 to In order to provide a simple but eiiicicnt locking bar 22 I provide thelatter ,ivith re- Y cesses 27 in o which the angularly bent end 28 of each locking pin is adapted to extend,
Therefore in assembling the structure the ends 28 of the locking pins are lodged in tho recesses 2-7 and these assembled parts are then placed in the guide Way and by reason of the positionjof the locking pins between the locking bar 22 and the'u'all of the guide Waydisengagement of the locking pins with reference to the locking bar is prevented.)
' The referencecharacter 29 indicates a keeper rigidly secu'redin the guide way 23. as for instance by means of a bolt-30. This keeper 29,is provided with latch recesses 31 and 32-e1igageable by means of a latch 33 carried by'locking bar: 22. Latch may be conveniently, and economically formed by reducing, the end of bar 22 as clearly illus DIOVlClG a tratcd in the drawings to thus latch member WlilCll' is relatively resilient andone which may be snappedinto engage ment With either of the two latch recess-es fkeeper 29,. WhenElat'ch 33 is in engagement with latch recess 31 locking pins 25 are in their operative position but when latch 33 has been released from latch recess 31 locking bar 22 may then be moved longitudinally until latch 33 snaps into engagement with latch recess 32. This position of the parts is illustrated in Figure 3 and by reference to this figure it will be noted that the locking pins are in a position where they project slightly: into the openings 26 for engagement in the grooves formed in the locking posts adjacent the sockets therein. Thus the locking pins in this position form stops for positioning the locking posts within the openings in the manner clearly brought out in my co-pending application, Serial No. 163,234. filed January 2st, 1927.
As a simple but efiective means of releasing latch 33 I provide a key member 34 adapted to be inserted in the guide way 23 parallel to one surface of keeper 29. The keeper is preferably formed with one or more slots 35 with which ribs 36 on the key member 34 engage. Upon the insertion of the key member one longitudinal edge there of engages the bevelled end 37 of latch. 33 and springs this latch out of engagement with the latch recess 31. It is then possible to move locking bar 22 longitudinally until the latch has been snapped into engagement with latch recess 32.
With this construction the locking bar is positively secured in its operative position and is prevented from being completely withdrawn. Obviously latch recess 31 could be eliminated and the bar 22 held in its operative position merely by the friction between the parts.
IVhile an embodiment of the invention has been illustrated and described herein somewhat in detail it will be readily apparmit that various changes in many of the details of construction herein illustrated may be resorted to without departing from the spirit and scope of this invention and to this end reservation is made to make such changes as may come within the purview of the accompanying claims.
\Vhat I claim as my invention is 1. In a looseleaf binder, a guide, a locking bar slidable therein, a latch carried by said locking baiyakeeper having a plurality of latch recesses engageable by said latch and means for disengaging said latch from one of said latch recesses.
2. In a loose leaf binder, a locking bar construction comprising, a guide, a bar slidable therein, oneend of said bar being formed into a resilient latch, a keeper fixed to said guide and engageable by said latch and means for springing said latch to disengage the same from said keeper, said means including a member engageable in a slot in said keeper,
3. In a. loose leaf binder, a locking post,
a locking pin engageable therewith and a control means therefor including a slidable bar carrying said locking pin, a keeper having a plurality of latch recesses and a resilient latch carried by said control means ongageable with the latch recesses in said keeper.
4. In a loose lea't binder, a locking bar construction con'iprising a guide, a slidable bar formed with a recess and a locking pin having a portion extending into said recess and held therein by engagement with said guide.
5. In a loose leaf binder, a locking bar construction coi'nprising a guide, a bar slidable therein and formed with a recess and a locking pin provided with an angularly bent end engaging said recess and held in place by engagement with said. guide.
6. In a loose leaf binder, a guide, a bar slidably mounted in said guide, locking pins carried by said bar, a keeper provided with latch recesses, a resilient latch carried by said bar engageable with said latch recesses and a key member insertable in said guide for springing said latch out of engagement withv one of said recesses.
7. In. a loose leaf binder, a locking bar construction including a guide, a slidable bar mounted in said guide, and a locking pin detachably engageable with said sliding bar, said locking pin being held in engagement with said bar by said guide.
8. In a loose leaf binder, a locking bar construction including a slidable bar having a latch, and a keeper having portions selectively engageable by said latch whereby said bar may be locked in one of a plurality of spaced positions.
9. In a loose leaf binder, a locking bar constrmiztion including a slidable bar having a latch, a keeper engageable by said latch. said keeper having a keyway, and a key engage-able in the keyway in said keeper for forcing said latch from engagement with said keeper.
In testimony whereof I affix my signature.
JAMES BARKER.
