To cllwhom it may concern;

- Be it known that I, GIANNI Bn'r'rINI, a subject of the King of Italy, and a resident of Paris France, have invented a new and useful Improvement in Plates and Plate- "for projection or for picture taking is dis.

placed with relation to a plate upon which are the images to be projected, or upon which the pictures are to be taken, said plate having a fixed position relative to the picture being taken or the screen upon'which they are projected instead of, as in the usual apparatus displacing the plate with relation to a fixed optical sytsem. More particularly my invention relates to apparatus of the above mentioned type, in which the pictures are projected upon or taken from a plane at right angles to the plane of the relatively fixed plate.

It is the object of the present invention to provide a form of plate and plate holder to be used with 'my apparatus of the above described type as claimed in my earlier ap plication above referred to and as described therein and also below in the present application. The invention can be applied to ordinary photographic plates or small size easily obtained'at relatively small cost.

In order that the invention may be readily understood I have shown in the accompanying drawings an embodiment of the preferred form of machine for utilizing the plate holder of ,said present invention and in the text WlllCQ, follows I have described said machine.

. In the drawings, Figure 1 is a diagram showing the principle upon which the invention is based; Fig. 2 is a general view of the box containing the mechanism, the cover being omitted; Fig.3 is a section on the line 33 of Fig. 2; Figs. 4. and 5 are end views, of the box represented in Figs. 2 and 8 from the right and left hand sides "respectively; Fig. 6 shows a plate maganine intendcdto be fitted to the pro ection apparatus; 7 is a section of the plate magazine on the line 77 in Fig. 6; Fig. 8

is a detail View of a plate with its plate,

holder frame; Figs. 9 and 10 are detailviews of the plate and plate frame; and Figsllto 14 are detail views showing a modified form of-,platc frame. j The principle upon which the apparatus 1s constructed is represented diagrammatically in Fig. l and provides for illuminating the photographs from a fixed source of light B including the usual condenser for proje'cting a pencil of parallel luminous rays, 7

the axis of which would first of all be par allel with the plane of the plate or band ii. carrying the pictures instead o'f'falling perpendicularly upon it as in all other methods of projection. The axis of the luminous pencil is then directed perpendicularly to the plate or band by means of a. prism or other reflecting surface C which would deflect it from the parallel direction By means of. anobjective D combined with another prism or reflectingsurface E and arranged on the other side of the plate or band the image is then projected on to a screen F arranged perpendicularly to the plane of the plate or band or in any other plane by employing suitably arranged sup plementary reflecting surfaces.

In displacing the objective D and the prism E and the reflecting prism C with an intermittent synchronous reciprocating movement parallel with the plate or band .f. the focusing is not altered and the photographs of the same row upon said plate will be successively illuminated and projected upon the screen F. It will thus only be necessary to lower or shift the plate or bani A transversely of the path of movement of the objective at the end of each travel or the optical system for obtaining the projection of the next following row of pictures.

During the displacement of the objective D and prisms E and C, the field of exposure or of projection experiences a sight dimr .nution or increase of size which is imper -cept1ble to the eye, which increase or de- [5 eetive is eonue "L r by :2 band A; .iidebie iengicil-ih the second or bhe seuree 01' over-spring hexee in mder to inhi1 of the prism A circular screen 5 upon 1L laterally ere support (:1? the obevieed Wi'h emernei e mwement ieeontrolied by in the eppe- L e on ,Jurlhwi g1 teeth on the cam SCL'OW o jeetlve as 111 e.

The tapof the cam screw 0 there is pet and boss are so arranged thatthe assein blage is retractedafterthe plate has moved a distance corresponding to that between successive rows of p1'ctures,thus feeding the plate one step, or to the next'row of pictures.

Each plate 8 is mounted by one of its edges inafra'me 7. Each plate is provided with a notch 24 (Fig. 8) corresponding to tooth or other-suitable stop 25 arranged in the frame so that the plates can always be placed in exactly the same position relatively to the frame and thus each picture be brought into exactly the same position in its faces withfa suitable number of springs.

Themagazine is placed onthe. box; a in such a waythat' slot 12 registers-with slot-15 in casing a. The front face of box '9. is; provided with: a one, or; moleslo s and one or more tappets 1e bymeans oflwhich the foremost plate may be, depressed, at the com mencement of the operation; of the machine so that its teeth 6 engage" withj vthe cam screw 3,

As shown gs; .7 and -gplate frame '1 "is provided withprojections 17, and notches16, the projection-ofone plate being adapted for engagement with the notch 16 of the succeeding plate, so that as one plate ,finally leavesthe magazine the succeeding plate will be pressed into operative engage. 'ment therewith by springs 11 and be pulled downward'so.thatieventually each plate will follow the other without interruption in such a manner that pictures may be taken or' projected during a long period of time.

The operation is as follows:

The plate magazine 9 is arranged in place on the projection casing a, care being had that the slot 12 registers with the slot 15, any convenient device being provided for insuring the correct position of the two as sings and keeping them in this position. The tappet 14 is depressed to cause the first plate to descend with its frame so that they occupy the position represented in 3. The prism 25 isthen in front of the first picture of the lower row of this plate.

If. the mechanism be operated by means of the handle m the parts occupying the po sition represented in the drawingand the Durin the dis laceinent MDL g and 2; 118 screen 3 is interposed in v.rout of rod 1' in mesh with the thread of the screw 03; the objective and the two prisms p and as a whole are displaced toward the right hand with an intermittent movement advancing when the rod. 9" is in the inclined part of the cams which then correspond to a change of picture while the whole remains stationary during the time that this rod traverses the straight t of the cams.

I c v 1 This operation continues untll each of the second row of pictures comes in front of the objective when the. operation of shifting the plate is repeiited. During the descent of the pl'ateQthe proj ection 17 of its frame come ing opposite the recess 16 in the following frame engagement takes place 9) be ing produced by the thrust of the springs 11 in such a manner that the plate which is being projected carries with it the following plate Which becomes arranged in the manner M end of member 26 is cut away in such fashion as to, preferably, leave a portion attached to the extreme end'tooth as at 28 The material between the last two teeth, 29 and 30, and between tooth 30 and the next adjacent tooth 31 is also cut away completely on that side of the rack member from which the groove Wall has been removed.

The other end of the same side wall of rack member 26 is extended beyond the end of the teeth sufficiently to enable a hook member 32 to be formed at the extreme end thereof said hook member lying next an adjacent space having the width of a rack tooth and this space being separated from the next inner rack tooth by a space equal to the space between the rack teeth.

Immediately adjacent to an appropriate edge of each plate there is cemented, or

otherwise suitably attached, a plate positioning member 33 of thin metal strip provided with aprojecting locking piece 34. This edge of the plate is inserted into the groove 28 of the rack member so that the locking piece-3t fits between rack teeth 30 and 31, thus preventing any linear shifting of the plate in the groove. To prevent the plate from slipping out of the groove 28, the inner. wall of said groove on theside opposite strip 33, is provided with a' leaf spring pressure member 34: preferably attached to said wall at its central point. This pressure member should be of spring metal and be given a preliminary set so that its end portions press against the'sides of the plateand hold it firmly against the opposite wall of the groove 28. v

The space between teeth 30 and 31 and the locking piece 34 correspond respectively with the notch 16 and projection 17 of the plate and plate frame shown in Figs. 6 to 10.

The modified form of plate and plate frame shown in Figs. 11 to 1-1 may be used with a plate magazine as in the form first shown or without a magazine the successive plates being fed into the slot at suitable times by engaging the locking piece 34 with the space between teeth 30 and 31 of the preceding plate. v
