Specification of Letters Patent.

Application filed June 23, 1908.

Patented Sept. 21, 1909. Serial No. 439,886.

To all whom. it may Concern:

Be it known that I, CLAnENcnD. TRUS- sELL, a citizen of the United States, residin 11 1 the borough of Manhattan, New Yor cit 1n the county of New Yorl: and State of ew- York, have invented certain new and useful Improvements in Temporary Binders, of which the following is a specification.

LI invention relates to temporary binders for lank books, account and memorandum books, and the like, in which the leaves may be inserted or removed at will.

- .The objectof my invention is to rovide a mf'iorary binder of simple, neat, c eap and construction, which ma r be opened or withdrawal of thesheets or leaves of paper.

My method of making the covers of the binder and securing the same to the operating metallic parts obviates the use of paste The covers. of my. binder will lie snugly ofiprating arts and sheets to reof the inder when carried in the pocket. My covers will not buckle or become distorted. as is usual. with covers of several layers pasted to ether. I provide also an. ornamental metallic plate at the exterior of the back of the binder which may be. availed of as a name plate or to indicate the contents of the binder.

' Figure'lof the drawings is a perspective view of the temporary binder in open position, the sheets not being in place. Fig. 2 is 8 sideview of a pair of the sheet-holding tongs, in closed position, the parts below I ing shown in section. Fig. 3 is a similar View showin I the prongs open for the withdrawal of the sheets. Fig. 4 is a similar View showin the sheebholding prongs and covers clos Fig. 5 is a ers ective'side view of two pairs of sheet- 01 ing prongs and the device for operating the same. Fig. 6 is a plan view the spring plate. Fig. 7 is; a rear view of the same showing the bindline 8-8 in Fig. 1 illustrating a modification of the means for securing the back and ferring to the drawings, 1. is a spring andcovms by means. of the binding plat; 3 whose end rejections 4 are bentpwar 1v an inward v h ug the Makes a m m ends of spring plate 1 to clamp together said sprin plate 1 and said binding plate 3 so as to ho d securelv between said plates the back 2 which is made integral with the cov ers (l as best illustrated in Figs. l. 2. 3. 4 and 8. As a fastening device auxiliary to the engagement of end projcctiousl with the notches 5 in spring plate 1. the cars 7 are struck upward, from binding plate 3 and driven through the back 2 to enter a )Ll[lll(- 8 in spring plate 1 where they are llent inwardly as best shown in Figs. (3 and T to hold the parts securely in position.

The spring plate 1 is comptsed of a curved base portion 9 from which are bent inwardly the parallel wings 10 which are provided with oppositely arranged notches 11. The sheet-holding prongs 12 are made in two pieces, one piece having at its lower end a deep groove or slit 13 adapted to receive and hold firmly a long, thin iece of still, spring metal l-l which extends engthwise of the binder, as most clearly shown in Fig. 5. and is so far embedded in said slit 13 that the outer sides of said slit form the female member of a joint to receive the male member 15 which is a long piece of stifi' spring metal corresponding to and parallel to the strip 14. The metal strip. 15 is embedded less deeply in the slits 16 of its prongs than is the strip 14.140 that the edge of the strip 15 forms the male member of the joint. At one outer edge of the hinder the metal strips 14 and 15 turn inwardly, at about a right angle to form the ogeratin fingers 17 best shown in Figs. 1 an 5. T e outer ends 18 of said fingers 17 are twisted to present :1 llut surface to, the operator as hereafter ex plained. Each sheet-holding prong has a notch 19 in its lower outer edge adapted'to be engaged by the inner edge 20 of one of the notches 11 in spring plate]. The upper sides of notches 19 are cut away at an angle so that they will notcontact with the wings 10 when the rungs are in open position, as best illustrate in- Fig. 3. Ad acent to each cover is a fly-leaf 21 composed of a metallic plate 22 around which is pasted a sheet 23 of glazed paper or similar material so s to envelop completely the same and eirtend outwardly beyond said plate, asbestallustrated. Fig. 1. Each 'fiy leaf 21 is apertured along it innere'dge "for the reception 9f the At each of the apertures Re the theta plates 22'are bos d bent 4 opening movement of the prongs is termi- I nated by the joints formed by theengagement of the outer metallic strip 15 are slightly at once. The

28 for the ward and sewed to so as to form the tube or pocket Fig. 2, the metallic strips 14 and 10.

The inward bossing plates 22 raises the edges so that they will not catch in the prongs 12. The bossin'g. or bending at the apertures 241also permits the fly. leaves to nest around prongs 12 when-the binder is closed, as best illustrated in Fig. 4. I show the fly leaves 21 in this application because they serveto guide'and protect the paper sheets 25 when the covers a or closed.

he stop pieces 21 are preferably located inside and adjacent to each' outer pair of prongs 12. They are retained in position by frictional Contact with spring plate 1 as closed position, asillustratedin V or bendingof the notches 13 of the apertures 2-1 by the edge of the below the level of the edges 20 which engage the notches 19 so that the spring. ressure of the plate 1 holds the sheet-holding prongs in closed positiom To open the prongs the operator with his fingers presses together the fingers 17 which cross each other near the point where'they turn up from the strips 14 and 15. This movement will open all the prongs still strips of spring metal 14 and 15 extending lengthwise of the temporarybinder serve to connect all the pair. o sheet-holding prongs 12 so that they \\'ll opening of open and close together. As the prongs open bit-St l' in -lthey rock sli htl on th eflgqg 20 n (ilt will be seen that the back, covers and so that their lower e ds are ai d, carrying pen or pencil holder are all made of one the joints between the edge of the strip 15 piece. preferably leather. I have found pigskin an excellent material for this purpose. By my novel method of manufacturing th hack and covers and securing the same to th opt-rating parts I dispense with the use 0 paste in securing together several layers o the cover. My binding plate is exposed a the hack of the binder where it presents 'a metallic surface which may be suitably in above the level of edges 20 so that the'pressure of the spring late 1 then serves to force the prongs apart and into the position shown iii Fig. The

contact of the upper surface of the metallic strips 1 1 and, 15 with the under surface of the 1 p pieces 31. To close the rongs, one pair is moved together by the scribed. 15 dispensing with a plurality P gers. This movement lowers the joint lielayers in the back and covers l a\'oid o tween the edge of the metallic strip 1. and jwl'lfllittble features such as buckling canst the notches 13 below the level of edges 20 by the drying of the paste or diti'vrenvtso that the spring plate 1, at the moment the shrinkage of the layers under varying court joint passes the level of edges 20, serves to i tions of temperature and moisture. My

At the inner prongs close the position of metallic strips end of said tube 28 is secured by paste i thin l 14 and 15 is shifted from that shown in Fig. collar 29 whose concealed edge 30 (Pig. 1) $3 to that shown in Fig. 2 separating the will serve as a stop to prevent the pen or 1 enter ends of fingers 17 so that they may be pertrci from grip ing tllI'OtatalLgl i again pressed together to re opentlie prongs.
