This invention relates to a method of decoration, ornamentation or painting that is carried out without the use of a pen, brush or pencil, and to secure in a simple way effects resembling those secured in oil painting by means of a brush, but without necessarily involving the skill of an artist.
According to theinvention, paint or colour is applied by hand. by means of stamps -of indiarrubber or other similar yielding substance, to give im ressions of leaves, flowers, flower-sprays, ranches, trees, figures or any other details for making up a picture or for the decoration or ornamen tation of an article or surface. For this purpose the printing surfaces of. the stamps used are provided with recesses or pockets within which the paint or colour to be applied is received, and so; that the paint or colour from the recesses or pockets is applied upon the surface upon whichthe impressionis to be made, whereby the paint or colour may be applied more densely at those positions. than at other positions of. contact of the printing surface with the surface upon which the impression is to be made. The paint or colour may be applied in greater or less density or quantity according to the pressure imposed in making (it) the impression and tothe form of the printing face. Thus the recesses or ockets are of such form and disposition tiat on impression the greater amount or density of colour will beapplied atthose positions at which the recesses or pockets are applied. Thus in the use of stampsffor the representa tion of flowers or leaves for example the greater amount or density of colour: may be applied at the positions between the petals or leaves in such manner that the, actual form of the stale or; leaves isindicated by the density of colour and form of the denser deposits in positions between. Similarly the printings'urfaces may be formed with slight or shallow recesses in particular positions according to the light and shade effects desired] and the form and graduations of density of, colour deposited adjacent the po sitions at which high light and deep shadow are required, it being understood that the dis ersion'of the colour or paint effected un er pressure when taking it up and when applying it inimpression may be varied according to the pressure applied, and that varying graduations of lightand shade may be secured by the amount or density of the colour taken up. Thus varyingv effects are secured by variation in the pressure applied in taking up the colour or paint as well as in the pressure applied in impression. The depth and shape of the slight or shallow cavities in the printing surface and of the recesses or pocketsreferred to are sodetermined that the subject. is represented in de tail by the deposit ofpaint or colour from posited and spread, or have been mixed in,
order'to produce particular tints or mixtures of colours that are to be applied, care being taken that by reason of its more or less uniform distribution no more of the palntor colour is taken up than is required in the impression, and that the stamp is applied with such a degree of pressure as is necessary according to the character of the impression to be made. I
The stamp having'the paint or colour thus applied on its printing face, is then impressed upon the surface to be painted,
decorated or ornamented, and by thus impresslng the stamp with a-pressure variable accordlng to the efi'ects to be secured, the
paint or colour is pressed. out of the re-.
cesses; or pockets and'from the very shallow cavities on the printing, face of. the stamp, and thus the paint or colour may be more or less irregularly distributed or in a manner resembling thatin which colour is applied in oil painting by means of a brush.
It-will be-understood thatthe printing surface may be variously formed to secure the effects aimed at; for example, in providing a.
stampfor the representation of a leaf ora number of leaves on a branch, insteadofi the printing surface being. fiat, it is provided with slight or shallow cavities following the conformation of the surface of. the respective leaves to be represented, andlwithrecesses or pockets between, so that on pressurebeing applied to the stamp on its impression upon the surface to be painted, the paint or colour is pressed out of the very slight or shallow cavities on the printing surface and out of the recesses or pockets which yield in the impression distinct lines or masses of paint or colour. These lines or masses of paint or colour are also applied in impression beyond the position of the edges of the leaf or leaves or other details, whereby lines of paint or colour are there applied by reason of its expulsion at the edges referred to. By such means the mint or colour is irregularly applied, and particular effects secured according to the pressure applied.
Or again, the printing face of the stamps map be provided with slight projections, ridges or other parts in relief between the pockets or recesses and such parts in relief in the case of a leaf or other object: represented may follow its formation or its outer edge so that thus at the positions at which these parts in relief are applied on the surface to be impressed, there is a minimum of paint or colour deposited and a maximum in positions beside such parts in relief.
The stamps for the representation of flowers, branches, figures, and other details may be similarly provided, and the printing surfaces formed with slight or shallow cavities therein or as irregular surfaces in such maliner that the colour is unevenly distributed in order to secure the effects aimed at. Thus the paintor colour may be applied in varying amount or density at positions in shade and high light according to the pressures imposed in taking up the colour and in applying it.
Thus the matrices from which the stamps or printing surfaces are produced may be engraved so that particular effects may be secured on impression according to the skill of the engraver or designer, but the effects aimed at according to the invention, may also be realized especially where the objects are small, in any convenient way involving recesses or pockets or other irregular formation of the printing surface, which may more or less conform to the characteristics or features of the detail or group of details represented.
According to the invention moreover the paints or colours used have varnish incorporated with them or a substance or substances having similar characteristics, thus oil colours usually employed in oil painting may be used, with the addition of a propor tion of varnish, or printers colours or inks in which a proportion of varnish is already incorporated may instead be used; and the paints or colours may be put up in collapsible tubes and may be applied on to a palette or other colour distributing surface on which the colours may be spread or be mixed in order to produce the articular mixture or tints desired.
Thus in the decoration of articles such as vases, bowls or other similar goods with a spray of flowers, a stamp is used to give an impression in a suitable colour of a branch or branches; a stamp may then be used to give an impression in suitable positions and colour of a spray or sprays of leaves applied on the b 'anches and a stamp may then be used to give in suitable colours the impression of a flower in determined positions with reference to the branches and leaves. The colours employed and positions at which impressions are made may be determined by the choice or skill of the individual, or may be indicated in properly executed examples of decoration, ornamentation or pictures that may have been reproduced from specimens of the method of the invention.
Thus for carrying out the method of the invention, examples of efi'ccts produced and of pictures, decoration or ornamentation involving a wide variety of details may be putup within the receptacles containing a set of the stamps required according to the subject and colours, together with a palette or colour distributing surface on which the colours may be spread for application upon the stamps.
Such a method of decoration. ornamentation or painting may be used for art teaching, and for decorating or ornamcnting a wide variety of articles of manufacture, it being possible to provide stamps and colours in sets for the representation of particular details of decoration, ornamentation or painting.
The invention comprises the use of stamps made of an elastic substance other than rubber.
The invention is particularly applicable in the decoration or ornamentation of silk or other fabrics and other goods that require washing or cleaning-the colour applied being incorporated with varnish.
The stamps may be conveniently provided in a form resembling pencils of wood and they may be provided of a uniform diameter or their bases may be enlarged and shaped according to the form of the printing surface mounted at their lower ends and provided as a layer of india-rubber or other suitable elastic substance which may be of a thickness of say f th or @th of an inch or more. The india-rubber is provided on its lower face as a printing surface by moulding or by engraving or by other means. The stamps may, however, take any other form, for example, a holder may be employed in the manner of spring pincers which are adapted to engage the rubber stamps by the provision of an extension on the top fat-e adapted to be engaged by the pincers, the form of the pincers being such that they may serve to engage the india-rubber stamp and apply pressure upon it for the purpose of hit) taking up colour and for impression. It will, however, be understood that no limitation is imposed to the form of the stamps used. a
The manner in which the invention 'is carried into effect is illustrated in the accompanying drawings inwhich Figures 1, 2 and 3 are enlarged views showing examples of stamps provided for carryinoout th method of the invention.
Figures 1*, l 1' are representations of the impressions made by the use of the stamps respectively represented in Figures 1, 2 and Figure iis enlarged detail sectional view taken on the line 44 Figure 3, showing the very slight cavities formed in the printing surface of the stamp. a
Figure 5 is an elevation of a stamp holder in the form of a cylindrical stem.
In the drawing a indicates the recesses or pockets and a the lines produced on impression by the paint or colour from the recesses or pockets; 2') indicates the terminal edges of the stamps, and b the lines produced the application upon a surface on which colour 18 distributed of a printing stamp having an elastic printing surface formed with shallow cavities extending across parts of the said elastic printing surface, and with pockets between the parts of the said elastic printing surface across which the shallow cavities extend and thereby applying colour on the said elastic printing surface and within the said shallow cavities and within the said pockets, applying the. said printing stamp in impression upon the surface to be decorated, ornamented or painted without wiping the face of the said printing stamp before impression, and expelling the colour from the said shallow cavities and distributing the said colour in greater amount atthose positions on the impressed surface that correspond with the said pockets, substantially as hereinbefore described.
2. In a method of decoration, ornamentation or painting as specified in claim 1, the step of taking up varying quantities of colour by variation of pressure upon the printing stamp, substantially as hereinbefore described.
3. In a method of decoration, ornamen tation or painting as specified in claim 1, the step of applying variable pressure in impression, substantially as hereinbefore described.
4. A printing stamp for use in deco-ration, ornamentation or painting having an elastic printing surface, the said elastic printing surface having shallow cavities extending completely across parts of the printing surface and pockets in positions between the said parts, whereby the normal impression surface is not fiat, substantially as hereinbefore described.
