Patented Apr. 7, 1959 METHOD FOR ERASING INKS AND GELA- TINE IMPRESSIONS ON TRACING AND OTHER PAPERS Maurice Jean Baptiste Ladeuze, Rosny-sur-Bois, and Pierre Toni, Champigny-snr-Marne, France Application September 12, 1955, Serial No. 533,808
Z Claims. (Cl. 134-6) The care and attention necessary for the removal of inks on tracing papers, by scraping or rubbing, are known, as also the slowness of this work and the risks of deterioration of the paper which will not stand up to successive scrapings.
The present invention overcomes these inconveniences. It has for an object a method for the erasing of inks and gelatine impressions on tracing papers, prints and films.
A product for use in this method is composed of alcohol and ethylamine mixed in a proportion according to the inks to be erased.
A mixture of l part of ethylamine with 9 parts of alcohol gives excellent results for preparing the surface to be erased upon by the action of the abrasive pad.
The method consists in wetting the surface to be erased with the product mentioned above, in rubbing with a slightly abrasive pad, and thereafter immediately drying with a clean cloth.
The use of the method can be usefully facilitated by an apparatus forming a practical holder for the pad, or permitting at the same time the feeding of this latter with a reserve of the product carried in the apparatus.
It has also been found that the abrasive pad is advantageously constituted by metal wadding, and that this latter should be preferably furnished with liquid near to the external opening of its housing in the apparatus.
The accompanying iigures show in sectional elevation and by way of non-limiting example some forms of construction of apparatus suitable for use in carrying out the method.
Fig. l shows the apparatus forming a holder for the abrasive pad. Fig. 2 shows an apparatus permitting also the feeding of the pad with a reserve of product carried in the apparatus. Fig. 3 illustrates a modification in sectional elevation, and the same is seen in section in Fig. 4 (section on the line 2 2 of Fig. l).
In the construction according to Fig. 1, the abrasive pad 3 (preferably a very ne metallic or plastic sponge), of a generally cylindrical form, is placed in a slightly tapered tube 4, then pushed into this tube by a solid handle 5 entering frictionally into the tube 4, until a sucient part of the pad 3 passes out of the tapered portion of the tube 4.
It is thus possible to dip the pad into a receptacle containing the product mentioned above, for carrying out the erasure desired.
2 When the extremity of the pad 3 extending from the tube 4 wears or gets soiled, the worn or soiled portion can be torn oil and the handle 5 is pushed into the tube 4 in order to` cause a new portion of the pad 3 to emerge from the tube 4.
In the construction according to Fig. 2, the pad 3 and the tube 4 are disposed in the same manner, but the solid plug is replaced by a hollow body 6 capped by a flexible hood 7. The cavity 8 of the body 6 communicates with the ring 11 and, by a capillary hole 9, with the pad 3. The assembly 6--7 forms a sort of dropper which the user ills with the product mentioned above by pressing and releasing the hood 7 whilst 9 is dipped into the product. This assembly is then introduced into the tube 4 to form a pusher on the pad 3, acting in the same manner as the handle 5 of the preceding example. The user can thus at will feed the pad 3 by pressing to a lesser or greater extent on the flexible hood 7. Finally, the apparatus comprises a cap 12 lixing by friction on the hood 7 and covering the tube 4 in such a manner as to protect the pad 3 when it is not in use, and avoids loss of the product by evaporation.
In Figures 3 and 4, the central tube 31 carries the metal wadding 41 which can be pushed by the pusher 51 threadable into the stopper 61 by means of a knurled knob 71. The whole is encircled by a reservoir 81 in which the liquid is introduced by the stopper 91. When the operator desires to utilize the apparatus, he removes the hood 101, inverts the apparatus and presses the body 81 which forms a burette and sends a small portion of the reserve of liquid towards the exterior of the wadding 41 through the conduit 111.
After having rubbed the part to be erased, the operator dries it with a clean cloth.
We claim:
1. A method of erasure of ink and gelatine impressions on tracing paper, electrotype prints and films, including the steps of wetting the surface with a liquid consisting of alcohol and ethylamine, rubbing the wetted portion with a slightly abrasive pad, and thereafter immediately drying with a clean cloth.
2. A method of erasure of ink and gelatine impressions on tracing paper, electrotype prints and films, including the steps of wetting the surface with a liquid consisting of alcohol and ethylamine, rubbing the wetted portion with a pad of metal wadding, and thereafter immediately drying with a clean cloth.
