n Iii thefdrawingsj like letters of reference indicate correspondingyparts in each'igure.

A is the'main casing of my device in which is supported a supplemental casing.v

A2 is a, partitioniwhich divides the'casi'g A into' two compartmentsA and A5. n

Bis the casing cover or table A2. The partition A2 extending crosswise inthe' casing `Ais provided with-a window of `transpa1rent`naterilA3-of aruby or a suitable Yco or.

B isa wi'ndow'lforined in the cover. The

window B islocated over 'the compartment. A5.

' C is across piece secured to the top ofthe cover B by screws C.

C is a printing frame .shutter comprising the portions Csfand Cj. The 'portion- C3 is connected by lthe hinge C5 to the cross-piece C. The portion C is connected by a hinge Ce'to 'the portion C3 of the shutter.

D is a stationary portion of my printing mask. -The stationary portion D comprises the arms D and D1, the inner edges of which are suitably graduated.

DHD, D1, and DG 'are stopproje'ctions extendingl upwardly from the 'stationary `member D. Thev member D is secured-t0 the top of the casing by a rivet D1.

D8 is a rocking shaft (seelFig. 3), journaled in bearingsDs so as to extend beneath the mask member D as indicated iii Fig. 3 of Vthe drawings.

`D1o is an eccentric or cam secured tothe rocking rod D.

D11 is'a lever connected to the opposite end ofthe rocking, rod'Ds. 'By throwing the lever D11 upwardly the rod D8 mayl be rocked to carry lthe'inajor axis of the eccentric D10 toward a vertical position bending the mask member D so as to sli glitlyspring thelinner edges of the `main vmember upwardly clear oi. the'top B of the main casing.

'Eend E are the'niovable adjustable mask members. y

D2 and E3 are links pivoted at one end to end to the casing top B.

'ioA

E* is a pointer member securedvtoV the a lF is agraduated arc scale with which `the pointer member E* coacts.'

E3 is an arc-shapedguide extending over i the pointer member in proximity to the end thereof and provided with notches E7 into which the end `of the pointer member springs. The movable shutter member E is provided with links E8 and Egand a pointer member E11 and a coacting graduated arc scale Emsimilar to the links E2 and E3, pointer member F and graduated scale E hereinbefore described.

, F is a suitable electric bulb forming an exhibiting light by which the operation may work. The bulb F is supported in the compartment A* of the main casing and F are a series of bulbsvform'ing printing lights sup.- ported. in the compartment `A of the main casing.

F2, F3', F, F5; are binding" posts exten ding through', the wall lA. oflthe supplemental cas in' .An

fare Contact fingers connected to thev respective 'binding posts Fi1 and F5.

G2 and Gs are spring fingers connected respectively to the binding posts F2 and F". The Aspring fing-gers G'r and G are provided withI curved outer ends G4, opposing' the similar outer ends G5 of the spring ingers .Gi3 is vertically movable bar held in brackets G7 and; G8. The bar GG is provided bar G extends.

.H is avcatch secured to the casing top B. y "H2 is an arm secured to the portion G4' of the shutter C2.

H3 is a right angular extension 'formed 'the outer end of the arm H2.

Il* is a spring pressed catch designed to engage with the catch H.

H'is an opening (see Fig. in -the' catch H4. n

H is a pin extending from the arm H2 through the opening H whereby the move-I ment of the catch is limited. The catch H4 is provided with a forwardly extending portion H7 for a purpose which will hereinafter appear.

VG24 isanotch formed in the extension G11 j of the' bar G.

' Gwis a coacting-catch pivoted on the bracket G1 so as to engage `with the notch. G2* when broughtfinto `the required posis tion.

Br through which the extension G11 oi the:

I is a. leafspring secured to the shutter member C4 to one side of the arm H2 and extending normally over the upper lend of the bar GG. It will of course be understood that the spring I is a stronger spring than the spring G12.

2 is a wire connecting the binding posts F3 and F5.

3 is a wire extending from the binding i F2 to the lower terminal of the lamp socket 5. The circuit returns from the upper, terminal of the lamp F by the common wire 3.

It will therefore be understoodthat when the vertical movable rod Gis in y theposition shown in Figs. 2 and 6 of the drawing the circuit extending from the binding posts F 4 and F 5 is closed so that all the lamps F are lighted. lVhcn however the rod G is moved upwardly so that the contactpiece G14 is carried between the fingers G2 and G, the circuit is closed from the ybinding posts F2 and F3 so as to light the lamp' F. The previously described circuit `through the lamps F is of course'opened simultaneously.

J is a spiral spring connecting the shutter portions C3 and 4 together.

K is a thin transparent sheet of Celluloid, which is laid over the glass B and over the edges of the movable mask members E and E (see Fig.l 5). L is a photographic lm which is laid upon the Celluloid K, tace downward.

M is a sheet ot photographic printing paper which is laid upon the top of the film. in placing' the lilm L in position the inner edges of the stationaryv mask member D2 are raised by the eccentric D1". The edges of the film are then slipped beneath the edge ot such stationary member into the required position, indicated by the graduation mark on the members D and D. The printing paper is then laid over the film C,the edges therectl abutting the stops D", D4, D5 and D2. The pointer arms It" and E are swung to the ,required position vindicated '.by the graduated scales E and Ef and according to the size oi the picture. By moviny the pointers E* and E as above describe movable mask members are carried inwardly to the required position to cover the edge of the film and superimposed printing paper so that the required width of white margin be printed around all the edgesof the'. hotegraph.- The sheet of transparent 4ce lulcid prevents `rthe edges of the movable mask members catching in the edges 'ofthe photograph when the movable membersarendng being adjustable. `rprinting frame is passed under the opening justed to the required position. The shutter C is then swung downwardly on top of the tilin and p aper.

It will of course be understood that while the paper and tilm are 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 operatorA sufficient light to make the required adjustment with the shutter in the raised position. The rod G is held in its upper position by the catch G15 engaging the notch G2* in this position. The contact piece G1" is held between the spring ingers G2 and G completing the circuit through the lamp F. When the shutter is closed so as to cover the lm and paper, the end Inl3 of the arm II2' engages the catch Gl'so as to release the catch from the notch G24. The spring I which is previously brouglitinto engagement with the upper end of the extension G of the bar G forces the bar GG downwardly, overcoming the upward pressure of the spring G12. fI;`he rod GG is then carried downwardly and the contact piece between the fingers Gr and G, thereby breaking the circuit through the lamp F and completing the circuit thro-ugh the lamp F. The shutter lis locked in its closed position by the spring catch H4 engaging the catch piece Il". T he photograph is then printed by means of the light from the lamps F and when suiiicient time has H4, releasing the catch Il". The shutter member C then instantly springs upward by means of the spring J, thereby simultaneously releasing the bar G from the pressure spring J and allowing the spring Gs tocarry the bar G upwardly. By this means as soon as therefpiired time for printing has elapsed the printing lights are in-1 stantaneously cut off by the opening oi the shutter. Y

I am aware that photo printing trames have been devised in which an outer frame .has been used having an opening for daylight printing, one oflhe sides of the open- In this form the ".a'tgfany predetermined speed and the degree @oi exposure depends on such rate of speed andthe size of the opening.

AIn my invention, which is for printing from an artificial lamp orlight,'ldo not wish to make anyprovisitm whereby the size of 'the opening` may be changed in order to provide a more or less quick exposure.

My invention is particuli-tidy designed to provide a simple and efficient means whereby `a margin of a.det'ermined width, that is to say, what is ordinarily termed a. White margin may be deliinitated clearly on the four sides of a print ofy any size within certain limits depending on the mahine.
