Burr, of -Rochester,*in' the county of Monroe and State of'New York, have invented certain new and useful Im rovements in Photographic-Printi -Me a; and-1.; "do

My relates to photoggarticularly to photographic printing, and it as. for its object to provide 5 I a simplefand-filfiexpensive mask adapted to.
" icture an be superposed' upon the sensitized'surfaee to produce a rint' having aclearly defined rder.
A further object'of the invention' is to so constitute the mask that indicating marks will be produced uponfthe print 'for the guidance. of the photographer in trimming down the print to a border of predetermine width, particularly when a'so called; itrim mingboard is used for this purpose. To these and other ends "the invention consists of certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features lie-h ing pointed out in the claims at the end of the specification g v In thedrawings: Figure I is a plan view of a printing-mask constructed in accord-- ance with and illustrating one embodiment of my invention, the relation between it and the sensitizedsurface-towhich it is applied being also indicated; Fig.2 is'a top Ian view of a print produced with the aid 0 my printing mask and-illustrating its appear-- ance be ore being trimmed; Fig. 3 is a persfiective view of a'trimming board in which t e print of-Fig; 2 is being trimmed, and Fig. 4 shows the print of Fig. 2 with one ed e trimmed.
imilar reference numerals throughout the several figures indicate the same parts.
In the preferred construction of my maskf a transparent and preferably rectangular sheet 1 is provided that is adapted to be superposed upon the sheet of printing paper or other sensitized surface and which may be conveniently constructed of a cellulose- Specification of Letters 7 muse-me a Gotcha-21,1811.

fitted to resist the'passage of actinic. rays and preferably'to totally resist them'so that jority of instances down this une'x of the reasons -b"eing that it' is so diflic'ultito to a uniform widthiand properly square'iip dis-further provided at'each corner of the picture area 2, or at least at diagonally opposite corners, with intersecting elongated tively with the adjacent si es of the openin 2 but removed therefrom and adapted to a from immediately adjacent portions of the sheet so that correspondingmarks a and b. are produced on the print. Preferablythese elongated portions are slots punchedfrom the sheet to admit all raysand fully exposetherfiortion of the print beneath.
between t ese slots and the opening 2, is of,
trimmed and finished print and leaves a corresponding and well defined angular 1mportion 5 on the mask, of course, completely as 1-18 iised' inlin ordinaryoentertof' tlie'-sheet..has"a portion 2 zwith straight sides admits off i the passage ofra'ys of lightfand; which "deg fines" the picture area on-theprint: This; portion-Ipreferto form 5 cutting 'an' openthe finished printr- To this end, the sheet 1 surrounds the opening 2, in the present em-- bodiment, but at other points than the cor ners its line of demarcation from the rest".
the sheets-hue trahSparent in the prefenedconstruction, is,'how"-, ever, colored red or jorange .or otherwise '65 the print fi'swithfan unex osedi area surrounding-the picture 'area a'ss dwn at A '2 #the picture area bein catedat Bw-lht ie is desired in t eras-- portions 3 and 4: runnin parallel'respec-b feet the passage of actinic rays differently e angular or L-shapedportion 5 of the sheet comgrised within theangles 3- 4, and f 1 the width of the border intended for theexposed portion a on the latter. This border of sheet isnot defined because hot neo es-l sary"where atrimming board. is used, as hereinafter described.
In="the printing-operation,"the sheet of, print ap'er is preferably of the size indi cated y dotted lines in Fig.1.} relatively to the size of the maskfso that its edges lie coincident with the ends of theslots Thus after the exposure is made, the marks ab on the print' extend to the edges of the print mper at their outer ends, and as .-.one s de each-mark which 1s m almem'ent with the tr'immingor outer-5 line ofthe in;-
, itcnded border width 0 of one side of the nrin't, extends beyond the line-.of the outer edge of the border widthi: on;the-adjacent side of the print, the latter-may be placed on the trimming bow-(has. shown in Fig.3,
and-the cut accurately started by bringing the 'knife down first along the margin or edgcline Z/ of the ma l-lo band .then at the mai'gin or edge line a of the mark-a, (Fig. 4) ,;as a. guide. The hnesofthe' four trimmingcfits and the size (ifjhcti'immed print ,are indicated by dotted lines in Fig. 2. It
I will-be noted that on whichever side the cut 1 is'made first, theguiding marks for cutting the'adjacent sidw'not removed with the severed piece though port-ions thereof are so severed, as shown in Fig. 4. Of course, the light openings 2,3 and 4 may be produced by -,rendering such portions of. the sheet .colorless to admit actinic rays instead of "cutting themput. F nrthermore, 1 the por-- tions 3-4 may be rendered opaque 'or entntcly resistive to-actlmc rays, While the border portion 5 is onlypart-ially resistive sheeti'ton the other, be proportioned to affect the passage-of the actimc rays-todifierent to\prod uc e a tinted instead of a wholly unexposed border; or the reverse, the-only essential' beingthat theseportions 3'=4 on the-one hand, arid adjacent portions of the degrees so that the rcsiiltin marks ab on "the print will be contrasting and distinguishable. p It 'is not absolutely essential to all purposes of my inventionthat the mask he of transparent material, butthis is preferable as it makes it much easier to properly position the mask with respect to the sheet of printing paper beneath it which would otherwise be concealed. 5-"
I claim as my inyention: I
1. As an article oftmanufact'ura'a photographic printing .mask embodying a sheet adapted to be inserted between the negative and sensitized surface and comprisinga rectangular center portion 0' n to the passage of actinic rays and; de ning the picture area, and a' surrounding portion ada ted to resist the assa e o'fiactinic rays to orm an unexpos'e bor er entire-print, the'sheet being provided with intersecting elongated slots beyond the border parallelwith adjacent sides of the picture area for producing guiding marks on the print. for trimming the latter down to a border of a predeter' face and composed of a material ada ted to resist the passage of actinic rays 0 light, said sheet being providedwith a central rectangular opening defining the picture area and with intersecting elongated slotted portions at the corners of the opening parallel with but removed from the edges of adjagenthsides of the latter for the purposes set ort NORMAN W.
