This invention relates to writing pads; and the primary object is to provide an improved pad characterized by its novel com- I immediate extinction of impressions.
sheet and a celluloid sheet, these being associated with the translucent sheet intermediate the other two, so that by making any marking or inscription on the celluloid sheet, it will be impressed on the parafiinecoated sheet by adhesion of the translucent sheet thereto. By breaking this impression the marking or inscription is obliterated. Innumerable impression may be made, depending on the presence of the parafiinecoating-between the translucent and bottom sheets. 1
Another object is to provide an improved means for obliterating the impression, consisting of an attached cord disposed between the bottom and translucent sheets and adapted to be .drawn between the same for separating them.
A further object resides in the provision of an assembly of the above-mentioned sheets, one of which is parafline-coated on both sides, permittin reversal of the coated sheet for doubling the life of the pad.
Still another ob ect'is to secure said sheets in a holder in a novel manner permitting removal for the substitution of new sheets or the reversal of the coated sheet.
Referring to the drawings:
Figure 1 is a face view of a writing pad embodying my invention; I
Fig. 2 is a perspective view of said pad showing several of the sheets turned up and the coated sheet broken away to show the holder;
Fig. 3 is a face view of a modified form of the invention;
Fig. 4 is a perspective view of the removabile sheets employed in said modified form; an
Fig. 5 is a perspective view of the holder used with this form.
My invention in its simplest form comprises sheets 7, 8 and 9, suitably secured together at one end, sheet 7 being preferably of Bristol board colored blue and coated on I one or both sides with parafiine or the equivalent, sheet 8 being of translucent paper or bond paper and sheet 9 being relativel thin celluloid. Bly marking on the top s eet 9 with a penci stylus or any other hard obect, an impression of such marking will be made by adhesion of the sheet 8 to the'parafiine-coated sheet 7 on the line of pressure as indicated by reference numeral 11, Fig. 1. This im ression will hold until sheet 8 is separate from the bottom sheet, thus v '1,s3-1,19z ATENT OFFICE breaking the adhesion and impression. The
sheets may be separated by simply pulling the sheet 8 from its unattached end after the fashion shown in Fig. 2.
In the present example I secure this assembly of sheets in a holder comprising a back 12 having atop portion 13 turned over one end. Said sheets are inserted between said back and to portion and secured therebetween bysuita le means, such for example as metal eyelets 14.
My invention also contemplates the provision ofaicord 15 suitably attached or con nected with thespad, and preferably disposed between the sheets 7 and 8 as shown in Fig. 4, In this example the sheets being similar to those,described above, one end of the cord is secured to the pad by a clip 16, which likewise holds the sheets 7, 8 and 9 together. To the opposite end of the cord is attached a stylus 17 for makin the impression. It will be manifest that I y drawing the cord between the sheets 7 and 8, they will be separated, thereby obliterating any impres- SIOIIS.
Another feature of my invention is the embodiment of the assembly shown in Fig. 4 in a holder having a back 18 and top portion 19, and theprovision of suitable means for removabl securing the sheets in the holder. To t is end I employ metal cli s 21 which fit over the turned edge of t e holder and are adapted to be clamped together, so that the spur 22 in one win of the clip pierces the several sheets. T ese clips secure the several parts together in operative relation and permit removal of the sheets 7, 8 and 9 as a unit from the holder, and likewise permit se aration of said parts so that the parafline-s eet 7 may be removed, reversed and replaced again, thereby presenting a fresh parafiine surface for the impression.
From the foregoing it will be ap arent that I have provided a writing pad a apted for showing impressions made by practically any hard ob'ect, and that theseimprcssions may be 0 literated at will and repcatedly made on the same surface. A writing pad of this character is especially desirable for the purpose of making notes, memoranda, etc.
It should be understood that in putting my invention into racticemany changes might be made in t e construction of the pad and in the materials employed without departing from the spirit and scope of the invention as expressed in the appended claims.
I claim:
1. A writing pad comprisin a back member and integral binding fla ormed on-said back member, a Wax-like co ored member, a flexible cord adapted to extend over said wax-like colored member, a tissue sheet superimposed over said wax-like member, a transparent graphite-resisting sheet superimposed over said tissue sheet and means for securing said flap oversaid back memher in a manner to hold all of said members together with said cord free to move over said wax-like member to erase any impressions made by marking upon said transparent superimposed member.
2. A writin pad including a back member, a colore member having a wax-like surface, a tissue sheet over said colored member, a celluloid sheet over said tissue sheet, a pencil-securing cord means for binding all of said members together and adapted to secure one end of said encil cord in a manner to extend 'interpose between said tissue sheet and said colored sheet to rovide a flexible erasing means by operatmg the free end of said pencil cord.
3. A -writing pad including a series of sheets bound together on one end, an erasing cord bound together with said sheets, said cord beingradapted to be operated to separate the sheets to erase any lmpression made by the adhering of said sheets together and adapted to sup ort a marking instrument on the free end thereof.
