REVERSlBLY-SUPPORTING WRITING-TABLET.

SPECIFICATION forming part of Letters Patent No. 569,169, dated October 13, 1896.

Application filed November 9, 1895. Serial No. 568,420. (No model.)

T0 @ZZ whom it may concern:

Be it known that I, DAVID IvAv BYERS, a citizen of the United States, and a resident of Hartwell, Hamilton county, State of Ohio, have invented a certain new and useful Reversibly-Supporting VVriting-Tablet; and I do declare the following to be a clear, full, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, attention being called to the accompanying drawings, with the reference-numerals marked thereon, which form a part of this specification.

This invention relates to improvements in writing-tablets where the paper used comes in form of rolls, and for which reason such tablets are provided with a suitable support for the paper-roll, which permits the convenient unwinding therefrom of the length of paper required at the time. They are further provided with means to separate the unwound portion of the paper from the strip after filled with writing.

The novel featu res consist in improvements of a construction whereby the unwound part of the paper may be supported and held in position in a manner which permits it to be used on both sides before being torn off from the roll. Great economy in paper is attained thereby, particularly where it is used merely for educational purposes and for practice in writing, as in schools, for instance, where the paper with the writing thereon is of no further importance after its immediate use at the time.

. In the following specification, and particularly pointed out in the claims, is found a full description of my invention, its manipulation, parts, and construction, which latter is also illustrated in the accompanying drawings, in which- Figure 1 shows in a perspective view the apparatus complete. Fig. 2 is a longitudinal section, Fig. 3 a side View, and Fig. 4 an under side view, thereof.

6 is the writing-tablet of suitable material, sheet metal or wood, and supported in an inclined position by a frame 7, connected to it and depending downwardly from the elevated rear end of the tablet and from the two sides immediately adjoining the same. To this frame are connected two rearwardly-extending brackets 8, preferably in line with the' sides of the tablet, which have slots 9, open at their upper ends for reception of the ends of the mandrel 10, which supports the paper-roll 11.

12 and 13 are two clamps reaching across the tablet, one at the upper and the other near the lower end thereof. They are supported at the sides of frame 7 and pivotally connected thereat ina manner which permits each of them to be adjusted in two positions with reference to the tablet. Of these two positions one is such as to cause the clamps to impinge against the top of the tablet, while in the other they are slightly but sufficiently elevated therefrom to permit free passage of the paper between them and the top of the tablet. In such adjustments the clamps are independent of each other.

The paper is manipulated as follows: Sufficient paper is reeled off from the roll to cover the tablet, the end of the strip being passed below the two previouslyelevated clamps. The lower or clamp 13 is now depressed against the tablet for the purpose of holding the end of the unwound part of the paper strips firmly in position for writing, as shown in Fig. 1. After this part of the paper has been filled with writing the lower clamp is elevated out of contact with it and sufficient more of the strip is unwound to permit the end of it, after being passed around and over the lower clamps, to reach up under the upper clamp 12, as shown in Fig. 2. Before the engagement with the upper clamp is accomplished the clamp 13 is lowered, after which the paper is turned around it and smoothened down and stretched toward the upper clamp, which is lowered as soon as the end of the suflicientlyftaut paper has come below it. This position of the parts is shown in Fig. 3. The reverse side of the previously-used paper is now in position for writing.l After being filled, the upper clamp is again raised, as shown in Fig. 1, permitting disengagement of the end of the now-on-both-side's-used part Y of the paper, which part may then be torn oif against the lower edge of clamp 13, which edge for such purpose is sufliciently sharp- IOO ened. This finds at the same time enough unwound paper in ready position for immediate use, as shown in Fig. 1 and as explained at the beginning.

In detail the clamps are preferably constructed as follows: The upper clamp is preferably formed of a piece of wire bent upwardly midway to form a convenient operating-handle 14, while the ends are bent downwardly and connect to the rounded ends 15 of a rocker-bar 16, journaled in the sides of the frame. The lower clamp consists, preferably, of a thin flat blade, which makes it at once suitable for use as a tearing-blade and forms no obstructing elevation to the writers hand while resting on the tablet. The ends of this blade are secured to arms 17, which in turn are connected to the rounded ends 18 of another rocker-bar 19, also journaled in the sides of frame 7. Knobs 2O are secured to and extend out laterally from the free between its ends to the under side of the tablet and bearing against the rocker-bars 1G and 19, which are preferably square between their journaled ends. This springdoes not interfere with the rotation of the rockerbars and at the same time exerts sufficient pressure for all practical purposes in this connection and which are to hold the clamps elevated in one position and cause them to impinge against the top of the tablet in the other position for the purpose of holding the paper. The eifect of this impinging action may be increased by covering the whole or only the contacting-surfaces of the clamps with rubber 22, or by having rubber strips laid on or inserted into the top surface of the tablet and below the clamps.

23 is a supporting bracket or shelf which may receive the Writing implement, pen or pencil, 'while notin use.

The location of the parts may be changed without going beyond the scope of my invention, in this way that the roll-paper supports project out from one of the sides, the paper passing transversely over the tablet, with the clamps at right and left sides thereof, instead of at upper and lower sides.

Having described my invention, I claim as purpose described, the combination of an inclined writing-tablet, a supporting-frame for it, roll-paper supports projecting from its elevated end thereof, swinging clamps pivotally supported, reaching across the tablet at each 1. In an apparatus of the kind and for the j end thereof, said clamps being from their pivotal supports extended inwardly below the writing-tablet and a spring on the under .surface of the latter acting by pressureon said inwardly-extended parts of the clamps, for

the purpose described.

2. In an apparatus of the kind and for the purpose described, the combination of an inclined writing-tablet, a supporting-frame for it, roll-paper supports projecting from its elevated end, clamps reaching across the tablet, one at each end thereof, rocker- bars 16 and 19, journaled in the sides of frame 7 to which the clamps are connected and thereby pivotally supported, and springs bearing against flat surfaces on the rocker-bars to hold them in adjusted positions. f

3. In an apparatus of the kind and forthe purpose described, the combination of an inclined Writing-tablet, a supporting-frame for it, roll-paper supports projectingfrom its ele.- vated end, rocker- bars 16 and 19 journaled in the sides of frame 7, a clamp 12 reaching across the tablet near the upper end thereof having an operating-handle 14 and its ends bent down at the sides of the tablet and con-V nected to the protruding ends 15 of rocker-A bar 16, a combined clamp and tearing-blade 13 reaching across the tablet near the lower end thereof, arms 17 whereby it is secured to the protruding ends 18 of rocker-bar 19, operatf ing-knobs 20 forclamps 13 and a spring 21 secured midway between the rocker-bars to the under side of the tablet and in contact with the former for the purpose described.

In testimony whereof I hereunto set my signature in presence of two witnesses.
