MASK FOR MAKING PHOTOGRAIHIC PRINTS.

Specification of Letters Patent.

Patented Nov. 20, 1917.

Application filed March 21, 1917. Serial No. 156,435.

To all whom, it may concern:

Be it known that I, CHARLES W. WILSON, a citizen of the United States, and resident of York, Pennsylvania, have invented certain new and useful Improvements in Masks for Making Photographic Prints,- of which the following is a specification.

My invention consists of a mask for defining the field which will be printed upon a sensitized hotographic paper and for definin a bor er portion surrounding the said fie d having thereon border marks or lines which will not only act as guides in trimming the sheets but will enable the customer to choose any one of a number of borders which may be preserved inthe trimming, thus rendering it possible to cater to the various tastes of customers.

In carrying out my invention I provide the mask with means whereby guiding marks may be made on the prints beyond the. margins surrounding the field, which marks Wlll enable the photographer to trim the print in any one of a number of ways to suit the taste of the customer, the marks being disposed in a novel relation so that although they act as guidesfor trimming they are so located as to render possible the choice by the customers of different borders.

I am aware that masks have been disclosed prior to my invention for exposing a i as in Letters Patent of the United definite size of field to be printed on the sensitized paper and to print or provide in the printing process guiding marks adjacent the corners ofthe field for trimming States, Nos. 1,060,618, and 1,061,727.

In the drawings;

Figure 1 is a view of the mask.

Fig. 2 is a view of a print made from the mask, this print not being trimmed.

Fig. 3 represents the print trimmed according to one of the designs from which a choice may be made.

Figs. 4 to 7 represent the print but with different styles of borders, all of which may be made by following either one of the several guides or indicating lines or marks made on the print through the mask when the print is being made from the negative in the ordinary way.

Fig. 8 shows the corner of a print provided with ornamental border lines.

In carrying out the invention I may use as the material of the mask celluloid or glass. It is provided with a portion 1 transparent or open for the passage of the light and having surrounding this open or transparent field portion a light resisting portion, indicated at 2. Surrounding the portion 1 and spaced apart-therefrom by an intervening light resisting section 3 of the light resisting body 2 I provide a border marking 4, which may consist of a continuous line, as shown, or this marking may be of any suitable design, character, such as fine scrollwork or the like. This border marking will permit the passage of the light and produce a border on'the print when this is developed.

I also provide a second border markin 5 separated from the first by an intervening portion 6 of the light resisting body and this second border marking may -be a continuous line like that first described, or it also may be of any desired design, such as scrool-work or a curved line or lines.

Any desired number of these border markings may be employed but I have found that two such markings will answer 'all requirements.

In the light resisting body or portion 2 I also provide guide markings shown at 7. These being out beyond the border markings and separated therefrom by intervening opaque or light resisting parts of the light resisting portion 2, these intervening parts being indicated at 8. These' guide markings will be printed on the paper when the \mask is applied thereto between the negative and the sensitized surface of the paper and they will serve for guidance in the trimming of the print. I

It will be noted that these markings are in line with the border markings, though separated or spaced therefrom and out beyond them, each marking being in line with one of the border lines or markings and there are twice as many guide markings at each corner as there are border markings surroundin the transparent. fields 1. The border mar iings may be continuous to en tend entirely around the open field 1 or they may extend only part way around, as the taste of the photographer or customers may dictate.

The print resulting from the use of this mask may be trimmed to present any one of a plurality or series of border efiects.

Fig. 2 illustrates the print resulting from the use of the mask before any trimming is done.

Fig. 3 illustrates one form of trim in which the print is cut away in line with the inner ends ofthe guide markings. This will leave a narrow margin 9 beyond the second or outer border line and between it and the ed e of the print or sheet.

if. a shows another style of print resulting rom trimmin alon line but leaving sa1d bor er line on the paper at the extreme margin of the print.

Fig. 5 illustrates another method of trimming b which awhite margin is left between t e inner border line and the edge of the paper, the outer border line having been trimmed away along its inner edge.

Fig. 6 illustrates another form of trimmin in which the inner border line is left on t e print while the margin outside of this border line is trimmed away.

Fig. 7 illustrates a further style of print resulting from trimming alongl the inner edge of the inner border hne so t at this will be trimmed away entirely leaving a white margin between the picture field and edgeof the paper. I

By these several forms of trims the photographer can suit the tastes of, various customers. The border lines together with the ide markings will enable the trimming to e done with ordinary shears or the usual form of cutter may be employed, such as shown in the patents above referred to.

I may employ as the mask a plate of glass sheet material aS celluloid having the border and guide markings together with the opaque fieldv provided thereon in any suitable way.

Instead of having the center 1 of transparent material an opening may be formed here and instead of making the border of transparent markings parts may be cut out from the material of the mask to provide this border marking.

It will. be understood that instead of celluloid or glass the mask may be made of any suitable material as paper.

What I claim is:

1. A photogra hic mask havin a central portion or fie d or the passage 0 light surrounded by a light resisting portion and the outer border 7 producing marks at the corners of an transparent border marks in said light resisting ortion with transparent guide marks a jacent the corners and out be and the border markings and separated t erefrom by an intervening part of the light resistin portion of the mask, substantially as descri ed. 1

2. A photographic mask havin a central portion or fie d for the passage 0 light surrounded by a light resisting portion and transparent border markings in said resisting portion substantially continuous and surrounding the field with transparent uide out beyond said border and separated therefrom by an intervening part of the light resisting portion of the mask, substantially as described.

3. A photo raphic mask havin a central portion or fie d for the passage 0 light surrounded by a light resisting portion and transparent border marks in said light resisting portion with transparent uide marks adjacent the corners and out eyond the border markings and separated therefrom by an intervening part of the light resistin portion of the mask, said guiding marks being at right angles to each other at the corners and in line respectivel with the adjacent border marks, substantlally as described.

4. A photo aphio mask havin a central portion or fie d for the passage 0% light and a light resisting portion surrounding said field with a plurality of markings or borders for the passage of the light arran ed in said light resisting portion and at dierent distances from t e field with guide marks separated from and out beyond the border markings and adjacent the corners thereof, there being twice the number of such guide markings at the corners as border mark- I ings and said guide markings being in line with the border markings respectively, substantially as described.

In testimony whereof, I afiix m si nature.
