TEMPORARY BINDER.

SEGIFICATION forming part of Letters Patent No. 591,638, dated October 12, 1897.

Application filed May13, 1897. Serial NoIA 636,279. (No model.)

To all whom t may concern:

Be 'it known that we, JOHN L. RILE and WVIL- LIAM J. RILE, citizens of the United States, and residents of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Temporary Binders, of which the following is a specification.

The invention relates to that classof binders sometimes known as rod binders, in which a movable rod is employed to hold the pamphlets or sheets in place within the covers.

Ourimprovement consists in extending the rod loosely through lugs at the top and bottom of the back, thus holding the rod always approximately in line with the back, but allowing suiiicient motion to permit the easy insertion or removal of a pamphlet or sheet when desired. The lug at one end, preferably the upper, is formed with a circular hole of a diameter a little greater than the rod to allow the latter the required angular motion without straining the lug or its fastening means. The opening in the lug at the opposite end is peculiarly formed and locks theV rod in strong contact with the leaves or sheets when it is forced into one portion of the opening, and when in another portion allows it to rise and relieve the pressure, but in both conditions the rod is held in engagement with both lugs and against displacement endwise.y

Another important feature consists in building up the inner face of the backimmediately adjacent to the lugs, so that its surface lies at the required short distance from the under face of the rod, or, if preferred, in contact therewith. These elevations serve to definite] y locate the points at which the pressure upon the leaves is greatest, and one of them also performs, with the elasticity or spring of the rod,'the important function of holding the latter in the locked condition.

The accompanying drawings form a part of this specification and represent the manner in which we have carried out the invention.

Figure l is a face View of the binder with the covers open or extended. Fig. 2 is a corresponding section taken on the line 2 2 in Fig. l. The remaining figures are on a larger scale. Fig. 3 is an end view of one of the ln gs, the inclosed rod being in vertical crosssection. Fig. et is a section corresponding to Fig. 3, taken on the line 4 4 in that iigure. Figs. 5 and 6 are sectional views similar to Fig. 4, but showing modified constructions.

Similar letters of reference indicate like parts in all the figures.

A A are the covers, of the usual materials, ornamented and covered in any ordinary or approved manner, flexibly secured to the back B, and adapted to be folded upon each other to form a casing or portfolio for the inclosed leaves or sheets. The back B consists of a strip of wood B,havin g the desired shape. lVe have shown it as semicircular in cross-section, extending nearly the whole length of the covers and securely cemented to the flexible material b, joining them. To the inner iiat face of the strip are fastened the plates D and E, one at the upper andthe other at the lower end. Each is bent sharply upward at a right angle, as shown, forming the lugs D E', through which extends the binding-rod F. The upper lug D is provided with a plain circular .hole d, receiving that end of the rod and allowing the latter suflicient liberty to turn freely therein and to be defiected angularly in all directions to the extent required without tending to loosen the screws c c or otherwise straining the parts. A knob F', secured to the rod beyond the lug D', prevents its withdrawal lengthwise. At the opposite end it passes through the lug E, similar n all respects to the lug D', excepting in regard to the shape of the opening therein. The latter, instead of being, as before described, simply a circular hole, is a peculiarly-formed slot. .The main portion c is approximately semicircular, extending from a point near the upper end of the lug E to the angle at the junction with the plate E and thence laterally at e on a slight` upward inclination, terminating in the circular pocketv e2,- about in line with the hole d in the other lug D. The pocket e2 is separated from the semicircular portion e of the slot by the downwardly-projecting tongue E2,the space between the point of the latter and the bottom of c being just sufficient to allow the passage laterally of the rod. A knob F2 at this end serves with the knob F to prevent the removal'of the rod, and also serves as a convenient means for grasping the end in transferring it from one portion of the slot to the other.

IOD

G G- are pieces of thin wood or book-board fastened upon the upper faces of the plates D E. They are preferably beveled away from the adjacent lug, as shown, and are concealed by the strip of covering material H, neatly applied and cemented. The highest point on the face of the piece G lies a little above the bottom of the slot e and a short distance inward therefrom, slightly obstructing the free movement of the rod past the tongue E2 and requiring it to be sprung downward a little in passing to or from the pocket e2.

The elasticity of the rod allows this deflection and immediately springs back again so soon as the tongue E2 has been passed. Thus constructed the movable end of the rod is held 3 lightly but reliably in eitherA portion of the slot.

The piece G with its companion lG at theIl opposite end also serve as pinching-surj faces upon which the leaves or sheets M are compressed beneath the rod.

To introduce a sheet M, the knob F2 is-:de-

pressed and moved laterally until that'end of the rod is forced past the tongue E2 and springs upward in the portion e of the slot.

In this position one or more sheets oran open pamphlet to beheld between the coversA-I` A may be easily slipped beneath the rod. The movable end of tlie latter is then forced i removal of thc sheets M or the reception of others.

One of the main advantages of our in-venl tion is the constant engagement of the rod and holding it in such position relatively to the back and covers that t-he latter vmay be f opened and closed regardless of the rod and .l without danger of loosening or breaking the in one portion until it is forcibly transferred `to the other, all combined .and arranged to fastenings by careless handling when the ro is in the unlocked condition.

The lockingmeans is simple and effective and the whole is inexpensive tomanufacture 'l D', E carried by the back, a rod F extending and is neat and ornamental in appearance.

Modifications may be made in the .forms i and proportions without departing from `the principle of the invention or sacrificing kits j advantages.

The vertical distance between the upper face of the piece G and the point of the tongue E2 may be varied, and will in some cases require to be more or less than here shown to accommodate thick pamphlets or masses of sheets or to hold a single sheet reliably.

In the form shown in Fig. 5 the pieces G G are in one, extending the whole length of the back'. In Fig. 6 these pieces are omitted,

the lugs and rod will be mounted on a stick erty to rise in the main portion of said slot and be locked in said pocket portion, all combined and arranged to serve substantially as herein specified.

2. In a binder, the back, the lugs secured thereto one -at each end, a rod extending longitudinally of the back, held at one end in one of said lugs, the opposite end extending -l through and held in a closedslot in the other,

the said slot consisting of a main portionand a pocket portion, a tongue separating said portions, the said rod being held in permanent engagement with both lugs with liberty, 'f -to rise .in the main portion of said slot and be lockedinsaid pocket portion, anda raised surface on Vsaid back adjacent to said slot,

adapted to lock the said rod in said pocket portion by thespring of the rod, all combined andarranged to serve substantiallyasherein specified.

3. The covers A, A and back B, the plates D and E fastened to the back and bent to form lugs D', E', a rod F extending longitudinally of said back, held loosely in one of said lugs and permanently engaged in the other inthe closed slot comprising the curved portion e land pocket e2 separated by the tongue E2., the latter serving to retain :the rod serve substantially as herein specified.

4. The covers A, A and back B, the lugs longitudinally of the :said back, held yloosely .in one of said lugs and permanently engaged IIO in the closed slot e, e', c2 in the other, and the knobsF F2 on said rod in combination 4with theraisedsuzrface G on said back in such relation to said slot as to lock said rod therein by the spring of the latter, and the raised surface Gvserving with said surface G and said rod to firmly grip the sheets M at those points, allsubstantially as herein specified.

In testimony that we claim the invention above set forth We affix our signatures Iin presence of two witnesses.
