LOOSE-LEAF BINDER AND THE LIKE;
Specification of Letters Patent.
Patentedo'ct. 12, 1909,
Application filed April 12, 1909. Serial No. 489,318.
To all whom it may concern.
Be it known that I, Jorm Hnnnen'r llnu'rrr, of 7 Priory road, EdgbastomBin mingham, in the county of Warwick, England, en ineer, have invented certain new and useful Improvements in and Relating to Loose-Leaf Binders and the Like, of which the following is a specification. i
This invention relates to loose leaf binders and the like and has for its object to provide an improved form of binding devicein which the telescopic filing members are locked 'in any position or released by one motion of a single key.
In a filing device made in accordance with filing members are adapted to be locked by the rotary movement of spindles provided mner telescopic members to be pressed against the"outer members.
Referring to theudrawings:-Figure 1 i-a a sectional elevation of a loose leaf binding device made in accordance with this invention, the upper and lower parts being separated; Fig. 2 is a plan showing the locking mechanism; Fig. is a section on line A Fig. 1. ,Fig. 4 is a detail.
a and b are channel shaped member which are. adapted to be inclosed and to be attached to the covers of a book or file.
(l c and f are pillars or telescopic tiling: members attached to the channel member (I and g [L j Z are pillars or telescopic filing membersattached to the channel member I;-
, (l a and 7.: are internal telescopic members sliding within 1: j c and f respectively.
as at m .m and the width of the metal between the slots is rediiced as at n to permit of the parts 0 forming the extremity of the telescopic mcn'lbers. (l and c being more easily flexed,
p p are spindles provided with cam shaped projections 1 which are adapted to lie normallywithin the slots m m.
'lbe pillars (Z and care reduced in diameter at their extremities and are provided with external corrugations, threads or locking ribs r r adapted to engage with corresponding corrugations or threads (shown in Fig. 1) inside the pillars [land j whenthe parts 0 are expanded. but ermits the pillars (l and e passing within tlepillars h and j s s are cranks disposed in the, channel 1 members a and attached to the spindles p p, v t -t are bolts adapted to be shot by a key inserted at w. 1
2) o are links connecting s s and .t i
Any number of tumblers such as H to may. be provided for the purpose of rendering the lock secure. i
In operation assuming that the papers or loose leaves-are placeclon the pillars, the, channel shaped plates a and I) are pressed toward each other and the bolts 1 t shot by inserting and turning a key, this movement rotates the spindles y) p and causes the cams q to press against the-inner Walls'of the pillars (I e and express the parts 0 0, so that the threads r engage with the corresponding threads within the pillars]: and j. where= by the filing'device securely locked in any position: to open the filing device the key is turned in reverse dire'ction which returns the points of the cams to a position within the slots and releases the corrugations from engagement and permits of the tiling device being opened.
\Vhat I claim and desire ters Patent is y 1, The improved loose leaf book binder cmnprising the combination of attachment plates. a plurality of pillars on each of said plates; at plnrality of pillars on one plate provided with slots and external lockin; ribs. spindles disposed within said pillars and cams on said spindles adapted to lie normally in said slots. a plurality of pillars on the other plate provided with internal locking ribs. means for partially rotating the spindles so as to press the external locking ribs on pillars so provided into engagement with the internal locking ribs on pillars to secure by Letcoacting therewith.
'2. The improved loose leaf book or hinder comprising the combination of attachment plates, a plurality of illars on each of said plates, a plurality o pillars on one plate provided with slots and external locking ribs, spindles disposed within said pillars and cams on said spindles adapted to lie normally in said slots, a plurality of pillars on the other plate provided with internal lock- 19? ing ribs, 0 'anks on saidspindles, bolts adapted to be shot by a key and links disposed between the cranks and bolts respectively whereby the cams and ,the spindle may be partia ly rotated for' the purpose of so provided with the internal locking ribs on pillars coacting therewith.
3. The improved loose leaf book or binder comprising the combination of attachment plates, a plurality of illars on each of said plates, a plurality o pillars on one plate provided with slots and external locking ribs, spindles disposed within said illars and cams on said spindles adapted to he normally in said slots, a pluralityof pillars on the other plate provided with internal locking ribs, cranks on said spindles, bolts adapted to be shot by a key and links disposed between the cranks and bolts respectively whereby the cams and the spindle may be partially rotated for the purpose oi pressing the external locking ribs on pillars so provided with the internal locking ribs on pillars coacting therewith, and tumblers adapted to be operated by a key and to coact with the bolts respectively.
4. The improved loose leaf book-binder comprising the combination of two plates, telescoping members on said plates, one of said telescoping members having a spring end, a cam having a part of its working face extending radially a greater distance than another part, whereby to form a Working rise adapted to engage such end, and means for producing a relative rotation of said cam and the spring end of said member to spread said end against the other;of said telescoping members.
5. The improved loose leaf book-binder comprising the combination of two plates. telescoping members on said plates, one of said telescoping members being hollow and JOHN HERBERT HEWITT.
