DEVICE FOR HOLDING AND CLA MPING PAPERS, 80c.

SPECIFICATION forming part of Letters r tentlvo ssnei 2, dated December 25,1894. Application filed October 1,1894. Serial No. 524,568. (No model.) I

act description, reference being had to the drawings which accompany and form a part I ofthis specification, in which Figure 1 is a perspective view of one of my paper holding clamps, one side longitudinally and vertically cutaway, to show the working parts beneath, along the dotted line no of Fig. 7, and showing also, in dotted outline other working parts beneath the supporting board, A. Fig. 2 is a longitudinal section showing Fig. 1 with the board depressed upon its spring support, and its clamping jaw raised and tilted up for the reception of papers. Fig. 3 is a perspective view of the working parts, the springs, C O, and the board, A, removed. Fig. 4 is a longitudinal vertical section of my paper holding clamp, in which the position of the clamping jaw is reversed, for holding papers when perforated, and the construction somewhat modified for such purpose. Fig. 5 is a similar view to that shown in Fig. 4 with the board depressed upon its spring'supportand the clamping jaws open for the reception of papers. Figs. 6, 6 and 6" are views in detail of the devices I prefer to use for attachment of my supporting spring or springs to the board, A; and Fig. 7 isatop view, through the board, A, which is shown in dotted outline, of the working parts of my device when modified as described.

The lettering in all the figures is uniform. My invention relates to the construction of devices for clamping and holding papers and the'like of the general class shown in United States Letters Patent of G.Bernard Petsche, No. 405,596, and bearing date June 18, 1889, in which a boardor other support rests at one end upon a desk or table, or is hung on a nail, and rests against the wall, the other end being raised and supported upon a flexible spring, so that when considerable pressure is applied to the top surface. of said board, near its upper or free margin, the spring will yield and thesupported end thereof be depressed,

the middle layer, a

said movement of depression serving to actuate mechanism automatically whereby the clamping jaws are forced open, against spring pressure so as to permit the insertion of loose sheets of paper, and when the pressure is re leased, the action of said spring, as the free end of the board rises, will again force down the said clamping jaws andgrasp and hold said papers.

The construction which forms the subject matter of my present invention embracescertain advantages of cheapness, and efficiency' of operation, and capability of being modified to'suit certain special requirements in use, which differentiates it from said patented invention, and for which I desire to secure Letters Patent.

'A is a board which may be of plain Wood, but for which I prefer to use a special construction of material, as it is essential to the operation of this device that the lower margin of said board and its free edge along the clamping surface should be flat and not warped, or the device will tilt to and fro and interfere with its use in writing upon the pa pers held therein. For this purpose I use a board built up in layers, and glued together, so that the grain of the wood of the two outer layers, a and a shall run across the grain of More than three layers may be used if desired, but three give the best results in my experience. I use this board finished with varnish, or the like, along the edges, but not supported in panels, or doweled to marginal strips, the edges being free, as cut. These boards may-have a width of six, eight, or twelve inches, and a length of twelve, fifteen or more, according to the dimensions of the papers to be clamped. I

usually round the corners somewhat to avoid scoring the table upon which the devicemay be used. At or near its raised upper part I pivot one or two bell-crank clamping arms, 3 B, having a rise, 13', nearest the point of 1mpjingement upon the board of the clamping jaws, B, to clear the board and give room for .the papers, and a downwardly extended portion,B at the bottom of which is the pivot,

B by which the said clamp is secured'to the pivot support, A, of the board, A. The clamping arm is continued beneath this pivot at an angle, either backwardly, as in Figs. 1, 2 and 3, or forwardly, as in Figs. 4, 5, and 7, ex.- tending along beneath the free or raised margin of the board, A, longitudinally, so that, when downward pressure is applied to this raised end of the said board, the free angular ends of the clamping jaw will engage upon a fixed support below, and the said clamping jaw will be rocked upon its pivoted support, A" B which will cause the clamping ends of said jaw or jaws, B, to be raised from said board in the arc of a circle, upon B A as a radius, and form an opening into which papers may be inserted between said clamping jaw and said board. To compress this clamp, and support the raised free end of the supporting board, the spring 0 is employed. This spring may be of any form desired, flat, coiled, or angular, and may be secured in various ways, but I prefer to use the construction shown, in which the spring or springs, O, are of fiat metal, and secured at one end to the under side of the board, A, so as to allow the free end, extending to the front raised end of and beneath the said board, A, to be vibrated under spring tension. These springs may be attached directly to the free under arms of the clamping jaws, forming their bell-crank extensions, B B which will thus rest upon the table and form the support for the free raised end of the board, A; but in such case these arms will grind by their extremities upon the table beneath, even if provided with rollers, as they may be, or else will cause slip of the board when it lies upon the table, since the distance from the unsupported margin of the board, upon the table, to the pivot, A, and thence to the end of the bell crank arm, is greater than a straight line along the table between the said points. To avoid this I prefer to secure the free ends of the springs, C, O, to a preferably wooden cross bar, E, to the upper surface of which they are attached by screws, s s, Fig. 7, and I make this bar, E, cylindrical in form, so that as the springs are compressed it will correspondin gly rotate upon the table and thus avoid the difficulty described. To this bar, E, I secure the hearings or bell'crank attachments which actuate the clamping jaws. In Figs. 1, 2 and 8 I use a small link, D, secured at one end to an eye, F, of the plate, F, which secures the spring, 0, to the bar, E, which gives a very free movement, while in Figs. 4, 5 and 7 I merely run the bell-crank arm through a sleeve between the plate, F, and the cross bar, E, shown at F so that the angular-distance is taken up by play on the bar, E, instead of on the table, T. The plate, F, I prefer to extend along the bar, E, the distance between the springs, C C, when I use two springs, which I do not always do in narrow constructions, as they thus insure accuracy of spacing, and also afford slide bearings for the bellcrank arms, B of the clamping jaw. In the middle portion I form this plate, F, with a loop, F thus producing a handle by which thewhole device may be hung up on a wall, as it operates quite as well in this position as when horizontal. At F I also show a central rise in the plate, F, forming a socket into which engages, when desired, the bolt, G, see Figs. 4, 5 and 7, whereby the device may be held open to remove and tile papers away, when the perforating holder is used instead of a simple compression clamp. This bolt I make to work so free in its keeper, G, that by merely turn ing the device in one way or another, with the spring, 0, compressed, it will drop in or out of the recess, F The forward end of the bolt, G, is bent downward and then forward as shown at G Fig. 4, to permit it to enter thesocket freely, and a small stud, in rear prevents its escape. The small screws, 9 g, secure the keeper to the under side of the board, A. To secure the rear end of the spring, 0, to the board, A, a simple perforation may be used, and a screw, 0 G, as shown in Fig. 6; but to insure a strong strain I use the device illustrated in detail in Figs. 6 and 6". When two springs'are used, as in Fig. 6" I join the spring holders, 0 C by a crossbar, 0 so as to maintain distance, as is done by the corresponding plate, F, at their forward end. This bar, 0 also assists in strengthening the board, A. A small metal casting open through, at C, and having a raised forward edge, a is provided with a pin, C cast on, and projecting upward toward the board, A. Screw holes, C, enable this holder to be secured to the under side of the said board, as shown in Fig. 6. The perforation, c, at the end of the spring, 0, is hooked on to the pin, 0 and its forward end is then drawn down, after the screw, 0 has been applied, and secured to the bar, E, and the clamp, B, secured to the same holds all in place under strong tension, the spring, 0, being strained over the raised edge, 0

In Figs. 1, 2 and 3 the bell-crank pivot, 13, of the clamping arm is at the extreme front of the board, A, and the clamping jaws extend to the rear, which is the margin which rests directly upon the table; but in Figs. 4, 5, and 7 the clamping lever is reversed, and is seated in a slot, or slots, A in the board A. I usually use two of these clamps, as shown in Fig. 7. They are cast flatwise, or

otherwise formed, and have pivot supports,

B B Fig. 7 which rest ,upon the board, A, alongside the slots, A and are covered and held down by the rearward extension, B A, Figs. 4 and 5, grooved transversely for their reception, and thus forming a pivot bearing. The forward free ends of these clamping jaws are separately pointed as shown in Fig. 6,and above these points I prefer to form eyes, B, whereby a cord may be inserted and the perforated papers drawn off, when the bolt, G, is locked, and tied up in bundles, by means of said cord or string.

To insure perforation, I provide a raised seat, A preferably of cast metal, at the forward end of A, in which are openings, 0. for the reception of the points, 13, as shown, which when impaled they are drawn forward around the looped or raised parts, B B of the clamping arm, when they will lie fiat upon the board A, face side uppermost. I also modify my device in various other ways without departing from the principles of my invention.
