PAPER-Fue HOLDER.`

SPEGIFIGATION- forming part of Letters Patent No. 283,596, dated August 2.1, '1883.`

Application led March I6, 1853. (No model.)

and useful Improvements in Paper-File Holders; and I do hereby declare that the follow# ing is a full, clear, and exact description of my said invention, referencebeing'had to the accompanying drawings, which form a part of this specification.

My invention relates to certain novel-construction .of file-holder 'for newspaper and periodicals.l

It consists, essentially, of a bar having points or pins to engage with and pierce the edge or inner margin of the paper, and a movable slot or bar having a recess inthe edge to receive the points i' these pins, and so attached to the iirst bar that inthe movements to open and to close. the two bars the clamping-edge is always parallel with the opposite bindingedge of the stationary bar havingthe points, and an equal pressure along the whole length is thereby obtained.

The following description fully explains the nature of my said inventionand the manner in which I proceed to construct, apply, and use it, the accompanying drawingsbeing referred to by figures and letters.

In the several views employed, Figure l represents the holder in use as a newspaperdile.

Figs. 2 and 3 are views of tworpositions--closed and open. Figs. 4 and 5 are cross-sections through-:t zr, Figs.l 2 and 3, but on a larger scale. Fig. 6 is a modification showing the application oi' a lever and handle to work this' movable bar. parts of Fig. G. f

The stationary bar or back part, A, of the file has a ledge or lateral projecting part, a, the full length of the bar, into which ledge a number of pins or sticking-points, I) b, are set at short distances apart. p Their distance from the portion A of the bar regulates the amount of paper to be given for the clamping-bar to act on.

B is the movable slat or bar that Fig."7 is an edge view ofthe constitutes the clamping-jaw. It is set against the inner face of the bar A, so that it works over the ledge a. The inneredge, a', of this movable yslat has several deep slots or recesses, d d, equal 'in number to and in line with the points b b. These are to Vreceive the points or pins, and to ,permit the two edges to come together upon the paper with a firm pressure.

To connect the'bars A. B and produce the parallel movement, I iX upon the inner side or face of the bar A a number of studs, E, and

Vpass theirfree ends through slots f f, provided 6o for the purpose in the bar B, after which I fix 'on the ends outside of the slotsf a head or nut, g. These slots are parallel with one another, and have an inclination toward the ledge or portion a., so that a horizontal pull or movement of one bar upon the other will produce a lateral movement and separation of the meeting parts o a', while by the application of force inthe opposite direction the two bars will close together. This mode of connecting the twogbars insures a parallel movement, and gives an equal pressure oi' the two surfaces for the entire length of the bars. The inclinationof the slots f f gives a considerable amount of leverage to the clamping-bar, so that a considerable number or thickness of papers -can be rmly clamped and held between the two meeting parts a o. Where a large number of sheets-such as newspapers and periodicals-fare to be held, the inclination of these slots f should be greater than in the construction of holders for. lighter matter.

For a light small character of iile I employ the construction shown in Figs. 6 and 7 ofthe drawings. In this modification the clampingbar has slots that are formed on a less degree of inclination or on a curve, and a lever, H, with a handle, h, is applied tothe back bar to move the bar B up and down.

f AV locking or fastening device to hold the movable bar B down into place is afforded by making' one of the heads or nuts g movable, so that itcan be set down against the bar B. Forthis purpose one of the studs E may be screw-threaded on the end, and the nut y made to work in it. In a long stick or holder more than one of these binding nuts or heads can be used, if required.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

IOO

er, consisting of-the bar A, having the ledge 3. In combination with the bars A B, held a and pins b b, the bar B, having the recesses together by the parallel slots ff and studs or d d on the inner edge, the slots f f through the bolts E E, the locking device consisting ofthe 15' side, and the studs or bolts E, fixed in the bar threaded stud E and binding-nut g', for the 5 A, substantially as described, to operate as purpose set fortln set forth.
