TEMPORARY BINDER.-

specifieation of Letters Patent.

Patented Mar. 20, 1917.

Application filed August 30, Serial No. 47,977.

To all whom it may concern:

Be. it known that we, VVILLIs E. GAYLORD and HENRY J. GAYLoRn, citizens of the United States of America, and residents of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Temporary Binders, of which the following, taken in connection with theaccompanying drawings, is a full, elear, and eXact description.

This invention relates to certain improvements in temporary binders for loose leaves, magazines, newspapers and other periodicals and is somewhat similar to that set forth in our Patent No. 1,067 ,019, of July 8, 1913, in that it involves the use of one or more pairs of jaws. and a sliding plate having-cooperativemeansfor opening and closing'theaws as the plate is moved endwise together with suitable means for" operating the plate.

The main object, however, of our present invention is to enable the jaws to be opened and closed with greater rapidity, and at the same time to reduce the Weight and cost of manufacture by reducing the number and size of the parts.

Inother' words, we have sought to produce the same action of the jaws as in our patent referred to by means of a single plate and a relatively short adjusting screw therefor, as

distinguished from double plates and-wedges and long screw spindle of the patent.

Another object is to utilize the bearing for the screw as a brace between the sides ofthe sheet metal frame or support, thus permitting the use of comparatively light sheet metal in the formation of thesupport.

Other objects and uses will appear in the following description.

In the drawings 7 Figure 1 is a perspective view of a binder embodying the features of our invention.

Fig. 2 is an inverted plan of the same binder, omitting the cap plate, a portion of the sliding plate being broken away toshow the underlying parts of'the j aws;

Figs. 3 and l are enlarged longitudinal and transverse sectional views taken,respectively, on lines 3 -3,and 4 Fig. l. t

Fig. 5is'a top plan ofthe binder showing the jaws as partly opened. 7

Figs. 6 and 7 are perspective views of the jaws of one pair;

As illustrated, this binder consists of a tubular case or main supporting frame'oonr.

posed of a base section 1 and a cap section '2- the base section 1 having its opposite edges provided with parallel lengthwise flanges 3- projecting from one side thereof and formed in their outer faces near the free edges thereof with lengthwise grooves 4l.

The cap section -2- is co-incident in length with that of thebase section 1 and is preferably concavo=convex in cross section with its convex face outermost and its opposite longitudinal edges bent'inwa'rdly to form ribs which are slidably'interlocked with the grooves 4. so that the cap section may be removed or replaced from either end by sliding it upon the base section, and when in operative position is firmly locked thereto and forms therewith an intervening chamber for the reception of the jaw-operating means, presently described.

The fianges3 of the base plate are spaced some distance apart and are folded inwardly a slight distance over the main body to'form guide grooves 5 for receiving the opposite edges of and guiding a longitudinally movable jaw-operating plate 6 which is slidable' in said grooves, and are provided with separate pairs of diagonal slots 7 one pair for each pair of jaws, each slot being adapted to receive a stud or pin 8- on one of the jaws, said sliding platebeing also provided at one end with a head or flange -9- having a threaded aperture' 10 for receiving an operating screw 11.

This screw is located within the tubular case or frame and wholly within the ends thereof and. journaled. near its outer end in a crossbar 12.' and is held against endwise movement by pins -13 passing through apertures in the screw spindle and engaging opposite faces of the cross bar -l2, the outer end of said spindle being flattened at .l4 to receive a correspondingly formed key, not shown, but by which [the screw may be operated to shift the plate of, in this instance three, guide flanges -1T disposed in the same flat plane at substantially right angles to the main body of the jaw and spaced uniform distances apart to form intervening slots 18 of substantially the same width as the flanges so that the flanges of one jaw may ride freely in the slots of the'companion jaw, the object of which is to form a comparatively broad bearing for each jaw and to distribute such bearing approximately the entire length of such jaw.

These flanges rest upon the inner face of the main flat body of the base section --1- and the combined width of the flanges and slots between them is substantially equal to the length oil the opening -1l5-- through which the jaw projects, while the main body of the aw is of greater length than. the combined width of: the flanges -17 and intervening spaces 18 so to overhang and engage the portions of the base plate at opposite ends of the opening to hold the jaws against inward displacement through the openings it being understood that the flanges 17 are of sullicient length to eX- tend transversely across the opening nearest its jaw and some distance beyond the portion of the base plate between the openings, as shown more clearly in Fig. l.

The openings 15 of each pair are of the same length, but are offset longitudinally a distance corresponding to the width of one of the flanges -17-, while one end. of each jaw extends beyond the adjacent flange a greater distance than the opposite end be yond its adjacent flange corresponding to the width of one of the flanges so as to enable the jaws to be assembled upon the base plate directly opposite each other with their corresponding ends in the same transverse planes at substantially right angles to the longitudinal center of the base plate.

The outer longitudinal edges of the jaws are bent inwardly a. slight distance toward each other to form gripping ribs 1$)- for effecting a more positive grip upon the article which may be impinged between them.

Each jaw is provided with one of the studs 8- secured to one of its flanges -17 and projecting through the corresponding slot '7 in the sliding plate -6, the inner ends of the studs being provided with heads which are of slightly greater diameter than the width of the slots -7 for engaging the inner face of the plate -6 to more effectively hold the latter against inward diagonal movemeut while being operated to open and close the jaws by means of the screw ---11.

As illustrated, the studs -8 of each pair of jaws are secured to adjacent flanges 17, one stud on the flange of one jaw and the other stud on the adjacent flange of the other jaw, which causes the studs to be arranged in staggered relation and necessitates a corresponding staggered relation of the adjacent slots -7.

The slots of each pair converge in the same direction, in this instance from the screw end of the plate 6 toward the opposite end at relatively steep angles to each other approaching a right angle so as to cause a rapid movement of the jaws from one extreme position to the other by a slight movement of the plate -6- and its operating screw 11, and owing to the staggered relation of the slots of each pair, it is necessary to extend one of the slots across the end of the other slot as illustrated in Fig. 2, it being understood that these slots are of sullicient length diagonally of the plate "6*- to allow the jaws to be moved the :tull .width of the openings -15-, and therefore, the jaws may be opened a distance corresponding to the combined width of the openings 15- of each pair, thus permitting the instrument to be used to bind or grip any article, such as pamphlets or newspapers having a thickness or combined thickness within the range of adjustment of the aws.

In the operation of clamping an article between the jaws, said jaws are opened a sutficient distance to receive the edge of said article between them by turning the screw in one direction, and thereby shifting the plate 6 endwise, whereupon the article is placed between the jaws with its edge against the outer face of the base plate -land the screw 11 is then turned in a reverse direction by means of a key to operate the plate -6 for closing the jaws upon said article with a sutficient degree of firmness to retain the article against accidental displacement, after which the key may be removed and the binder with the article clamped therein placed in position for use without liability of being withdrawn, since it is necessary to use the key to release such article.

lVhat we claim is:

1. In a loose-leaf and pamphlet binder, the combination oi? a tubular support having a base section and a cap section, the base section having separate sets of jaw-openings, separate sets of jaws movable in said openings transversely of the base-section and provided with guide flanges slidable thereon, a plate slidable lengthwise of the baseseetion across and upon said flanges and provided with separate sets of diagonal slots, one for each jaw, those of both sets converg ing in the same direction, studs on the jaws riding in their respective slots, and a single screw for operating the plate.

2. In a loose-leaf and pamphlet binder, the combination of a base plate having jawopenings therethrough, jaws movable in said openings transversely of the plate and having laterally projecting flanges resting thereon, a jaw-operating plate slidable length- In Witness whereof We have hereunto set Wise of the base plate across said flanges, and our hands this 18th day of August, 1915. provided With relatively short slots disposed at an angle of more than forty-five degrees to each other, studs on the jaws riding in saidslots, and means for moving the jaw- Witnesses: operating plate endWise and holding it in its M. VIOLA HOWLAND,
