To all whom it may concern:

Be it known that I, EDUARD.BACHMANN,'2\ citizen of the Republic of Switzerland, residing in Seebach, hem Zurich, in the Canton of Zurich, Republic of Switzerland, (whose post-office address is Seebach, near Zurich) have invented a new and useful Apparutus for the Production of Pictures, Patterns, and the Like by Photographical Method; and I do hereby declare the following to be a full, clear, 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, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

1 have uppliedior patent in Switzerland on March 28th 1905, Patent No. 31759; and in Germany on January 9th 1906, application No. 8199.

This invention relates to an apparatus for the production of pictures, patterns and the like by photographical method which pictures show a similar reguable for preparing patterns forembroidery, for the engiaving of checks and the like.

One form of construction of the present invention is shown in the accompanying drawings and two forms of a part of the some with patterns that have been prepared thereby.

Figures 1 and 2 show a ground plan and a middle sectional elevation respectively of one form of such part. Figs. 3, 4 and 5, plan, longitudinal section, and cross section respectively of the other form. Fig. 6 is :1 view of. the whole apparatus in partial section. Figs. 7 8, 9 and 10 are patterns prepared by the apparatus.

The base plate 1 rests on a frame a, which carries a reflecting surface b sloped towards a source of light 0. The ground plate 1 has an opening and receives a frame 2 which carries the ground figure serving as base for the production of various figures. A plate 4, is carried by four columns, 3, fitted to the base plate 1. ..n objective 5, directed downwards is arranged in the middle of the plate, 4, and can be covered over by a flap, 6. A photographic camera, 7, is arranged above the objective and has a back, 9, resting on a plate, 8.

The plates 4 and 8 may be moved relatively to each has a scale provided on a ring, 16, over which a pointer, l

17, fastened on the frame, 2, projects. The central.

l opening, 18, of the plate, 14, is for the most part covered over by a disk or mask, 19, firmly screwed to the plate, 14. The disk or mask, 19, has a recess or opening, 20, with a central angle of 45 while the scale, 16, shows sixteen equal divisions. The opening, 20, is covered over by a photographic negative, 21., which carries the ground figure and is held to its support by clamps, 22. Four pins, 23, serve for fixing the frame, 2, to the base plate, 1.

With the arrangement shown in Figs. 1 and 2, the photographic negative, 21, on which a ground figure of any kind has beeh applied by hand, by means of a relief copying apparatus or a Rose-engine or the like, is laid on the mask, 19, so that that part of the ground figure which has to be utilized for the production of the pattern is situated above the opening, 20, and is then fastened in the manner described. Then the whole arrangement is placed on the base plate, 1, and is sealed from above against the light in the manner shown in Fig. 6, while the light coming from the source of light, 0, can enter through the above-mentioned opening of said plate. The part of the ground figure situated above the slot, 20, is then photographed and afterwards the objective is covered over by the flap or cover, 6, and

present case this is taken corresponding to the'central angle of the slot, 20, viz., 45. The corresponding part of the ground figure is new again photographed so that in addition to the picture already existing on the plate in the back, 9, the same pictureis directly photoformed consecutively on this plate. As thus, how ever, taken together do not in this special case form any figure complete in itself, theyare formed on a second plate in a similar manner. 'Both the plates are mirror picture to those of the other plate and iso forth a photographed together. The pattern shown in part in Fig. 7 is an example prepared in this manner. Instad of two ground figures of the same kind, two ground figures of different kinds preparedin this manner may be combined to form a picture.

flected. image) will be understood at once, if, for :instance, along the lower radius of slit 20 (Fig. 1) a fiat mirror is erected perpe'ndic ularly to the picture surface. In the same manner as the picture appearing in the mirror will join the bounded part of the ground figure of the. negative, the single pictures of the one photographic plate are joined to those of the other photographic plate and then the plates are photographed together as described. An endless number of various patterns may be formed from one and the same ground graphed beside it. In this manner eight pictures are then developed and so placed with their picture aids together, that the part pictures of the one plate fit as I rosette shaped figure and then both the plates are again the disk, 14, turned through a certain angle. In the The meaning of the expression mirror picture (refigure, according as one or other part of the same is placed over the slot, 20, and according as this slot or its central angle is larger or smaller. According to the displacement the partial figures may be more or less interwoven or may be arranged at definite distance from each other. For example, each second part of the scale may be skipped over when exposing. From the first pattern produced from the ground figure, according to the same process, the most numerous variations can be obtained, as is shown by holding any desired part of Fig. 7 between two flat mirrors standing vertical to the plane of the picture and arranged at an angle to each other, for

instance, if two flat mirrors are placed on the dotted lines on Fig. 7 and held perpendicularly to the drawing,

a figure like that shown in Fig. 10 will appear in the murors, which figure is obtained on the photographic plate by photographing in the manner described the part of the ground figure which is-bounded by the ,Either a separate'mask, 19, may be used for each slot,

20, or several slots may be arranged in the same mask. Further the construction may be such that for the purpose of producing a figure as shown in Figs. 7 and 8, after the firstround the mask, together with theplate', can turn and then can be so adjusted by repeating the same proeess that each new part figure is superimposed on the figure already formed on the plate by the first exposure. This was done in the'first process described by combining together the two part figures on the two separate plates. Furthermore, by dispensing with the mask, 19, the slot, 20, can be arranged direct on the disk, 14, or the ground figure maybe arranged in the mask, 19, itself without any special slot, 20. This ground figure-can be transferred in the form of unconnected tracings or holes passing through the whole mask.

I Naturally the means for displacingthe mask as well as the form'of the latter may vary from that described.

According to Figs., 3, -4 and 5 the frame, 2, has a carriage orJsIide, 25, which can be moved forwards or backwards by means of crank, 26, and screw spindles, 27', on which nuts, 28, work or turn. The slide, 25, has two flat rails, 29, situated across the frame, 2, said rails being parallel to each other and are firmly clamped at both endsbetween the small plates, 30, carrying the nuts, 28, and can be moved as desired'towards each other in the direction of movement of the slide, 25. A scale, 31, is arranged on both sides of the frame, 2, in

order to be able to exactly measure the displacement of the slide, 25. On the rails is situated the photographic negative, 32, carrying the ground figure, above which photographic negative two opaque strips, 33, are placed and like the negative, 32, are firmly held to the rails, .29, by the screws, 34. Under each of the rails, 29, is situated one end of each of two opaque covers, 36, the other ends of which are situated on a spindle, 35, arranged in the frame, 2. These covers can as desired be moved with the slide, 25, or moved alone or wound up and down. A glass plate, 37, serves as support for them, which glass plate is held by angles, 38 on angle iron, 39, situated along the side walls of the frame, 2. Pins or studs, 23, serve for fixing the heme, 2, on the base plate 1.

With the arrangement shown in Figs. 3, 4 and 5, the patterns may be produced for example in the following manner, the principle of which will be understood by observing a fgure between two mirrors parallel to each other. The ground figure is successively drawn along under the objective and photographed. When one has thus prepared a strip of desired length on the photographic plate, the plate is developed and then tightened up in place of the plate, 32', so that this negative serves as ground figure. This strip is then photographed in a similar manner, so that finally a complete rectangle results (see Fig. 9). If the ground figure itself is of oblong shape, then the desired pattern can in certain cases be prepared in one course of the slide, 25. With this arrangement also the most varied figures or patterns may be produced, when for example, only a fractional part of the ground figure is photographed; or when moving along the same, even when the whole ground figure is exposed by an amount which is smaller than the extension of the same in the direction of the motion, as was done in producing the pattern shown in Fig 9. It also serves for arranging various pictures or drawings on each other on the same plate, such for example as may be desired for producing a number of smaller negatives on one large plate for the purpose of reproduction in photolithography,

autotypy and the like. There is also the great advantage of being able to expose pictures, which finally have to be arranged on the one and the same plate, for various periods corresponding to their various characters. In this method a fresh picture is inserted as ground figure each time the arrangement is moved.

The patterns produced with the device according to Figs. .1 and 2 may be further extended or vice-versa with the arrangement above described. Here also the individual parts may be modified in their arrangement and construction as desired.

The whole apparatus may be so constructed that it can be used horizontally and in certain cases, as for example when using a constant source of light, the exposure may be effected directly.

Quite irregular figures may be used as ground figures, as also various formations, suchas flowers and parts of plants, according to the object one has in view. The transfer of the ground figure on the sensitive plate can also be made by contact, in which case the objective is not employed.

The pictures produced by this apparatus may be of What I claim is:

1. In an apparatus of the class described, the combinatlon with a camera, of a movable support tor a ground figure to be photographed, and means for moving such support determined successive distances with relation to the camera to permit repeated sharply adjoining, more or less interwoven'or' disconnected photographic impressions to be taken thereof upon a single sensitive surface.
