MEMORANDUM PAD Application led November 23, 1929. Serial Ko. 409,309.
This invention relates to improvements in memorandum pads of the type on which memorandums or notes may be made by the pressure of a stylus or the like passing over the writing surface and which surface may be readily cleared for vplacing the same in readiness to receive another written memorandum, whereby the pad may be termed a perpetual one.
I appreciate that various types of memorandum pads similar in principle `to that above mentioned have been constructed in which a varied assortment of means have been devised for clearing or erasing the written memorandum from the pad, .such as sliding bands and the like for separating the tissue sheets from the waxed or paraiiin member, which requires two hands to operate, one for holding the pad stationary and the other for sliding the erasing band lengthwise of the ad. In my invention the waxed or para member may be instantly moved to a position away from the tissue to clear the writing surface by'the'use of but one finger of one hand of an operator, thus allowing free use of the other hand for supporting a telephone `receiver when making memorandums over the telephone, or for any other use desired.
` Another object of the invention is to provide a perpetual memorandum pad in which the paraliin or waxed member is normally urged against the tissue sheets by spring -means, and manipulative means associated with said paraffin or waxed member for effecting the depressions on the said member' againstthe actionv of the spring means to clear the impression left on the tissue by the movement of a stylus thereover.
With these and other objects in view the invention resides in the certain novel construction, combination and arrangement of parts, the features of which are hereinafter fully described, are particularly pointed out in the appended claim, and are illustrated in the accompanying drawings, in which:
Figure 1 is a perspective view of my improved memorandum pad.
F'gure 2 is a vertical longitudinal sectional view therethrough.
Figure 3 is a top plan view of the pad with parts broken away in section.
Figure 4 is a detail vertical sectional view on the line 4-4 of Figure 2 Figure 5 is a vertical longitudinal sectional 55 yiew through a modified form of my invenion.
Figure 6 is a fragmentary top plan view of the same.
Referring to the drawings by reference characters, the numeral 10 designates my improved memorandum pad in its entirety and which includes a rectangular shaped casing 11 embodying an inclined top wall 12 and a removable back or bottom wall 13. The top inclined wall 12 is provided with a rectangular shaped window opening 14, while mounted within the casing 11 is a rame member 15 also havin a rectangular shaped opening 16 therein w ich registers with the win- 70 dow 14 in the top wall. This frame member 15 carries a transparent glossy sheet 17 which may be Celluloid or the like and which serves to close the window opening 14 in the casing, while disposed beneath the transparent sheet 17 is a soft pliable tissue sheet 18. The frame lmember 15 is held in position against the inclined top wall 12 by a movable back plate 19, the upper side of which is provided with a raised portion 20 of a size to freely tit into 80 the frame opening 16 of the frame 15, the said raised portion 20 being provided with a waxed or parafn coating 21 which is of a contrasting color than the color of the tissue sheet 18 and is preferably black.
The plate 19 is loosely mounted within the casi-ng but is held in a normal position against the tissue sheet 18 by expansion springs 22 which are interposed betweenthe plate 19 and the bottom wall 13 of the casing. 90 The springs -22 are disposed on equal sides of the longitudinal center of the plate so as to impart an even pressure to the plates. The springs as before mentioned act against the plate 19, which in turn maintains the frame 9" member 15 in position against the inclined top wall 12 of the casing.
Integral with the upper end of the plate 19 and extending through a slot 23 in the upper end wall of the same is an arm or the plate 19 ing away from the tissue 18 for a purpose to tively mounted `notes upon the pad by moving only be presently described. During the down- Ward movement of the plate, the bottom end of the plate fulcrums against the under side of the frame 15 to prevent any downward movement of said frame, the upper end of the frame being supported in a bridge piece or bracket 25. 'c
il In practice, assume that the pad 1s clear of any writing and it is desired to record a memorandum thereon, at which time the operator grasps the stylus 26 which 1s capto the casing by a flexible cord 27 and proceeds to guide the pointed end of the stylus over the smooth glossy sheet 17 and in so doing, the impression of the stylus causes the soft pliable tissue 18 to adhere or stick to the wax or paraiin coating 21, thus visibly displaying through the transparent sheet 17, the matter constituting'the notes or memorandums. To erase the memorandum or note, it is only necessary for the operator to place his iinger upon the manipulating handle 24 and depress the plate 19 against the action of thespring 22, and as the wax coating 21 disengages the soft pliable tissue sheet 18, the matter will become obliterated and disappears, whereupon release of the manipulating handle 24 the spring will return the plate 19 to its former position for rendering the pad operative to o receive the next memorandum. From the description it will .be noted that an operator may conveniently record memorandums or the stylus v26 thereover and to erase the memorandums he may depress the manipulating arm or handle 24 by the forefnger of the same hand, thus'permitting use of the other hand for any purpose desired, such as for the holding of a telephone receiver in recording memorandums over the phone.
In Figures 5 and 6, the structure is identical to that shown inthe preferred form with exception that instead of providing the manipulating handle 24, I provide a headed push butt-on 24 which rises from the back plate 19 and extends through an opening 23 in the t-op wall 12 of the casing. The remaining part of the form shown in Figures 5 and A memorandum pad' comprising a. rectangular shaped casing provided with an inclined top wall having a window opening therein, a glossy transparent sheet fitting against the inside of the top of said casing and closing the opening therein, a soft tissue sheet behind said glossy transparent sheet, a plate provided with a waxed coating on one' side thereof, of a color contrasting with that of said tissue sheet, springs interposed between said plate and the bottom wall of said casing for urging said plate with its waxed coating against said tissue sheet, the top end of said casing having a slot therein and a manipulating member extending from said plate and outwardly through a slot in said casing.
In testimony whereof I aiiix my signature.

6 being identical to those shown in the pre- I.
clear the pad in this particular orm it 1s necessary for the operator to place his finger upon the head of the stud 24 and proceed to depress the same, thus causing the back plate 19 and its Wax coating to move out of engagement with the tissue'sheet 18.
Having thus described the invention,what
