-:Be i t known-that I, J OHN B. WI'LIQYER a citizen of ztheUmted-States, and resident of St; Louis,.--Mis souri,' have invented certain 7 new and "useful Improvements in a Corn: bined Portable PhotographicApparatus and fication containing a full, clear, and exact description, reference being had tothe accom anying drawings, forming apart hereof.

. invention re latesto a portable photogra hic: apparatus, (particularly adapted for ma ing negatives, e same, and'then printing ictures from said negatives upon sensitize sheets or'cards, which latter-are subjected to the developing and fixing baths, and are then readyfor delivery. J cipal' object of myinv'ention is to The prln provide a simple, inexpensive apparatus,

which iscollapsi-ble in order that it may be aratively small area while folded into a'icom or stored, and byrneans bein transporte' of w ich apparatus finished rapiidly an cheaplyproduc'e v othe above pu oses, my invention con sists in certain nove I and arrangement of parts, which will, be hereinaftermore fully set forth, pointed out'in 30 the claims, andillustrated in the accompanying drawings, in which Figure 1 is a perspeotiveview ofmyimproved a paratus, showing ,the rear and right han sides thereof; Fig. 2 is a perspece tive view of the apparatus, showing "the left and front sides thereof; Fig. 3is a perspective view'ofthe a paratus, as it appears when collapsed and fdlded for transportation or storage; Fig. 4 is a view looking at the under side ofthe apparatus; Fig. 5 is a horizontal section taken G'nthe line 55 of Fi 1; Fig, 6 is a vertical section taken on the line 6-6. of Fig. 1.; Fig. 7 is a vertical section taken on the line 7-7 of Fig. 1.

Referring by numerals to the accompanying diawingsa-l designates the bottom board or table'of the apparatus, to which is fixed in any suitable manner the lower edge-- flexible material, which is impervious to light; and the upper edge of this wall is fixed to a rectang rails of which is hinged a top board, or cover,

the frame 3, thus providing meansfor holding theapparatus in anunfolded, or open, condition while in use;.and,' when the appa ratusis folded'for storage or trans ortation, these rods 6 swing downward and ie' against one another along the side edges of the bottom board 1, as shown in Fig.

ate 11 is one end of which is secured to the board 1, front of the opening 9. A cord 13 is secured to the rear end of the late 11, 'and,passes through a screw eye 14 ed in the board ladj'acent the right hand edge thereof.

Fixed on top'of the bottom board 1 and inclosing the openin 9is a rectangular frame 15, to one sideof w ich is fixed in any suitable manner the edge of a rectangular sheet 16, of celluloid, or analogous transparent, flexible material,

Located on the board 1, immediately to the right of the-opening 9, is a pair of guides 17, and arranged to slide between said guides is a rack bar 18, with which'rneshes a pinion 19 mounted on the end of a shaft 20 rotating in bearings2 1 and fixed on the end of. said shaft 20, op osite the inion 19, is a disk 22, which. isa apted to shift the rack bar18. Hinged to the forward end'of the rack bar '18 is a U-s'haped frame 23, the upright membersof which are grooved on their inner edges so as to receive and hold a photographic plateff p Arranged in any suitable manner in the flexible wall 2, and at such a point as to be directly in front of the platepositioned in the l frame-23, is a combined photographic lens 1 laitegnted. ie, 1909. v

Fixed to the underside of the. boamf board 1' is a socket 8,which rovides means rectangular. opening 9, at the sides ofv which,

to side a rectangular ,plateylfl,,which nor 9;" and secured to a retractile coil spring 12, the opposite end of e manually engaged when it is desired to rotate the pinion 19'an'd V Pivot'ally connected; to the corners of'the bottom board 1 arerods v6, the upper ends of which are engaged by .screws 7,;carried by and shutter 24, which shutter is operated in any suitable -manner, preferably by means interior of the apparatus. A correspondingopening 30 is formed in the right hand orof a bulb 25 arranged on theend of a flexible tube 26 leading to the end of the shutter operating mechanism.

Arranged in the wall 2 is a circular section 27, of flexible, elastic material,which is gathered, or arranged in folds; and formed in the center of this section is an opening 28, around the edge of which is arranged an elastic binding '29, which is adapted to fit snugly around the wrist of the operator of the apparatus while said a aratus is in use, and which bindin norma y draws the inner edge of the matei'ia 27 together so as'to exclude light from the tion of the wall 2, and secured to the insi e of this right hand portion of' the wall is the upper edge ofa rectangular flap 31, which normally closes said opening 30; and which flap will readily move to one side when the hand of the operator is insertedthrough the opening 30. r

Openings 32 and 33 are formed in the top 4, and in these openings are arran ed sec- ,tions 34, of-red glass; and locate immediately in front of the openin 33 is a hood,

or shield 35, which is arrange to fold down-j ward onto the top of the cover 4, as shown in Fig. 3, when-the apparatus is folded'and not in use. These 0 enings, provided with the sections of red g ass, permit the operator to readily observe the developing and printing operations, which take-pla ce on the interior 0 the apparatus; 1

An apparatus of my improved construction is prepared for use by arranging the body in anopen position, as seen in F igs. 1 and 2, and by arranging a supply of sensitized plates andsensitized sheets or cards within the ap aratus; and providing a pair 'of trays, wlnc are located on-the rear portion of the bottom board, or table 1; and one of which trays contains a photographic deerly developed, it is placed in the tray con-' veloper, and the other tray a fixing solution.

In the use of the a paratus, the operator passes the right hanrlthrough the opening 30, forces the flap 31 to one side, and laces one of the sensitized plates in the U-s aped holder 23. to move the rack 18 backward'or forward to obtain the proper focus, and the shutter of the combined lens and shutter is now opened to make the ex osure. After this action has been accomp 'shed, the-exposed plate is removed from .theframe 23 and placed in the tray containing the liquid developer; and when said plate has been proptaining the fixing solution.

The operations incident to the developing and fixing of the, plate can readily be observed by the operator through the openings left hand portion of the The disk 22 is now manipulated.

32 and 33, provided the section 34 of red glass, and after the plate has been re- 'moved from the fixing bath and is dry, said plate is positioned immediately over the opening 9 inside the'frame 15. The celluloid sheet 16 is now folded down onto the negative, and the sensitized card or sheet of pa er is now placed directly on top of said cel uloid sheet; and with the left hand pressing firmly on the sensitized sheet or card, the cord 13 is pulled outwardwith the right hand to move the plate 11 laterally beneath the bottom 1, thus permitting light to pass throug'h'the opening 9, thus makinga posla 4 tive print upon the sensitized sheet or card. After this operation is completed, the sheet or card is first subjected to the developing bath, then the fixing bath, after which said sheet or card is dried and the same is ready for delivery.

'An apparatus of myimproved construction is simple, inexpensive, can be readily folded for transportationor storage, is easily and quickly set up for use, and by'its use photo raphic prints are easily, quickly, and
