4M is 4a sheety of' photographie printing paper Whichj'sf"laid ,upon the top i of' the film. In' placing the' Vfilm' L in position the inner edgesyof the niask member D are raised by the eccentricDN. The vedges of the filmv arethen slipped beneath' the edge of such member irft'o the required position, indicatedby the graduation mark on the arms Dand D2 oftheI member D. 'The printing paper isthen laid over vthe filnifl'.

/the edges thereoflabutting. ther-stops D3, 3D1;v

DE? and D0. The pointer arms E* and Ea are swung to the required position indicated yby the graduated scales E5 and Ey and ac'- IUD iis

cordingto thes'ize ofthe picture; 4By mov-` ing the pointers E1and'E1. as' above described the movable mask members are car- .rie'd inwardly vtothe reqnired position -to cover the edge of the film and superimposed printingjpaperso that the required Widthl 'of White margin'may be left around' all theedges of the photograph. The sheet of transparent 'Celluloid' prevents the` edges of 13g edges voi' the photovraph when the movable membersfare adju ed to the required position. The shutter C is then swung downwardly on topbf the film and ipape'r.

' It l'will of course be understood that while thepaper and lm Aare being adjusted the lamp F is lighted so as to throw an orange or ruby light through the transparent window A3, serving to give the operator suiiicient light to make the required adjustment with the shutter in the raised position. The rod Gr6 is heldin its upper position by the catchxGr15 engaging 'the notch G2* in this` position. The contact piece G1* is held between the spring fingers G2 and G3 completing the circuit through the lamp F. Then the shutteris closed so as to cover the ilm and paper. the end H3 of the arm H2 engages the catch G15 so as to release the catch from the notch G24. The spring I which is previously brought vinto engagement with the upper end of the extension G11 of tlie bar G6 forces the bar G6 downwandly, overciming the upward pressure of the spring wardly to position the contact piece between the fingers G and G', thereby breaking the .circuit through the lamp F and completing the circuit through the lamp F. The shutter is locked in its closed position by the spring catch H4 engaging the catch piece H. The photograph is then printed means of the light from the lamps F and when suHicient time has elapsed the shutter is opened by pressing-upon the projecting portion HT of the catch H4. releasing the catch H4. The' shutter member then instantly springs upward by means ofthe spring J thereby simultaneously releasing the bar GrG from the pressure spring'J and allowing the spring GS to carry the bar G6 upwardly. By this means as soon as the required time for printing has elapsed the sides of a print of any size within certain limits depending on the. machine.
