Specification of Letters Patent.

Patented Feb. 13, 1906.

.tached from their holder and have other leaves expeditiousl and conveniently substituted therefor; an it consists of certain new and useful features of construction and combinations of parts especially devised to that end, all as hereinafter fully described, and specifically pointed out in the claims.

Referring to the accompanying drawings, which form a part of this specification, Figure 1 is a top plan view of a holder embodying my invention, its covers and leaves being Wide open outward and broken away near the back thereof, the observer seeing the inside of the same. Fig. 2 is a partial section at the dotted line 2 2 in'Fig. 1 of parts there shown. Fig. 3 is a partial section at the dotted line 3 3 in Fig. 1 ofparts there shown. Fig. 4 is a partial section at the dotted line 4 4 in Fig. 1 of parts there shown, the semirings of the binder being in the positions indicated by the dotted lines X in the last-mentioned figure.

Like letters of reference indicate corresponding parts throughout the several views. A is a trough-like back piece of the holder and is preferably substantially D-shaped in cross-section.

B is the back plate plurality of L-shaped slots B therein and transverse-lugs B thereon,;the latter being provided with concentric circular bearings B extending therethrough. The back plate B is formed, preferably, of 'a lower thin metallic plate I), having the integral lugs B stamped thereout and bent transversel outward therefrom, and a thin upper meta lic plate I), secured thereto by turning the side portions If of the latter closely over the edges b of the former, as clearly shown in Fig. 3. The completed plate B is next placed and secured upon the back piece A by means of screws 6 or in any other suitable manner.

O is a longitudinally-slidable rock-shaft,

of the holder and has amounted in the bearings B in the lugs B of V the back plate B.

'D represents semirings corresponding in back plate B and rigidly secured by one end D of each thereof to the rock-shaftO and projecting transversely therefrom and parallel to eachother through the L-shaped slots B in the back plate B and adapted to slide in the vertical arms D of such iL-shaped slots B and to be rocked over into and detained in the horizontal arms D of such Pin-shaped slots B by contacting the edges D thereof. E represents semirings, counterparts of and pprres onding in number with the semirings an parallel to each other and adjacent to the outer ends of the vertical arms D of the L- shaped slots B. F is'a spring coiled about the shaft D and included between one of the lugs B onthe back plate B, and one of the semirings D secured to such shaft C and normally acting through the latter to maintain the movable semirings D in operative relation to and engagement with their counterpart stationary semirings E, as shown in Figs. 1, 2,

number with the a-shaped slots B in thefast mounted on the back plate B,

and 3, except that in Fig. 2 the free ends of I the semirings D are broken away to show the semirings E back of such semirings D.

G represents covers connected with the back of the holder by means of the binding in the usual manner.

Whenever it is desired to the holder, the shaft C is s the semirings D are opposite the horizontal arms D of the L-shaped slots B, when such semirings D are rocked over thereinto and detained therein by contact with the sides D thereof, Fig. 4 showing one of the semirings D in such position. The free ends of the semirings D E are next inserted through circular perforations H inthe leaves H, and the semirings D are swung out of enga ement with the arms D of the L-shaped s ots B, and the action of the spring F will then restore the semirings D to the positions shown in Fi 1, therebysecuring the leaves H operative y in their holder.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is- 7/ 1. In a binder for loose leaves of books, in combination, a back plate having a plurality of L-shaped slots therein and transverse lugs thereon, the latter provided with concentric place'leaves H in d endwise until v v paral el to can circular bearings extendin therethrough, a longitudinally-slidable roc -shaft mounted in the bearings in the lugs on the back plate, semirings, corresponding in number With the slots in the back plate and ri idly secured, by one-end of each thereof, to t e rock-shaft, and rojecti transversely therefrom and paral el'to eac other through the slots in the ack plate, and adapted to slide in the vertical arms of such slots and to be rocked over into and detained in their horizontal arms, semirings, the counterparts of and corresponding in number with the hereinbefore- -mentioned semiringsand fast mounted, on the-back plate, parallel to'each other and adj acent to the outer ends of the vertical arms of the slots therein, ,and a s rin normally acting, through, the longitu inal y-slidable rock-shaft, to maintain the, movable semi; rings in operative relation to and in-engagement With their counterpart stationary semi rings, substantially as described.

2. In a binder for loose leaves of books, in

combination, a trough-like back piece, preferably D shaped in cross section, a back plate fast thereto and having a pluralit of L-shaped slots thereinand' transverse l ugs thereon, the latter provided with concentric circular bearings extendin therethrough, a lon itudinally-sl-idable roc -shaft mounted in 51c bearings in the lugs on the. back plate, semirings, corresponding in number withthe slots in theback plate and rigidly secured, by one, end .of each I thereof to the rock-shaft, and rojectin I transversely therefrom and l i other through the slots in the ack plate, and adapted to slide in the vertical-.armsof such slots and. to be rocked over into and detained-in their horizontal arms, semiring s, the counterparts of and corresponding in number-with the hereinbeforementioned semirings and fast-mounted, on the back plate,parallel to-each other andadjacent to the outer ends of the vert cal arms ofthe slots therein, and a sprin normally acting, through the longitudjna ly-slidable rock shaf t, to maintainthe movable sen1i rings in operative relation to. and engagementwith their coun art stationary semirings, substantially as escribed.

3. In a binder for loose leaves of books, in

combination, a trough-like back piece A, preferably D shaped in crosssection,- a back plate B fast thereto and having a plurality of L-shaped slots B therein and transverse lugs B? thereon, the latter provided with concentric circular bearings B extending there through, a .longitudinally-slidable rock-shaft C, mounted inthe bearings B in the; lugs B on the; back plate I B, semirings: -D,' corre-' sponding-innumberwiththe slots B in the back plate B and rigidly secured-by one end D of each thereof,=to the rock-shaftC, and projecting-l transvelsely therefrom and aralel to eac other through the. slots B in the back plate B, and ada ted to slide in the vertical arms D of such s ots B" and to be rocked over intoand to be detained in their horizontal arms D semirings E, the counterparts of 1 and corresponding in number with the semi rings D and-fast mounted, on the back plate B, parallel to each other and adjacent to the outer ends ofthe vertical arms D of the slots B therein, a spring encirclingtherock-shaft C and serving therethrough -to., ma intaino the movable semirings D inoperative relation to and engagement ,with their; counterpart stationary semiringsE, and-covers G, connected with the. backof the hold r, substantially as described.
