Fig. 10 is a pers ective view of the fingers for transferring t e paper from-the cutting device to the developing solution; and Fig. 11 is a detail sectional view of a part of Fig. 10.

My invention is especially adapted for making photographic prints of records, and for developing and fixing the print at a'single operation.

In the present embodiment of .the invention, a casin A is provided, comprising the base a, and the side walls a. A front wall a connec't's the sides, and is provided with a rectangular opening a therethrough, the said opening being adapted to permit the passage of the lens tube 1), the bellows b belng arranged partly within the casing, the front of the bellows and the lens tube being carried by a board b slidable upon a bracket 1) secured within the casing and projecting therefrom.

On the front of the board b are arranged brackets I), each bracket being provided with a longitudinal slot b whose lower edge is notched as .t b, and a mirror or other Irefleeting mediu n is supported by the brackets, the said mirror or reflecting medium bein provided with trunnions b for engaging t 1e notches, whereby the said mir ror may be adjusted toward and from thev board b the angle of inclination of the minror with respect to the lens being varied by rocking it upon its trunnions.

Below the lens tube opening a, the base of the casing is extended forwardly, and the s ess ends thereof.

side walls are inclined, and a door a is hinged to the front wall and rests on the inclined sides for a purpose to be hereinafter described. A record supporting frame a is hinged at a to the casing above the door a, the said supporting frame comprising side arms e between which is hinged a rocking support a having flanged ends as clearly shown in Figs. 1 and 2. The rocking sup port a is journaled on a bar or'rod (1 extending through the side arms of the frame, and having nuts a threaded on the outer By loosening the nuts the support may be placed in suitable'position, and after the nuts are tightened, it will be retained in its adjusted position. Notched arms a are secured to the supporting frame a on each side thereof, and engage pins (1) on the side walls of the casing, to retain the supporting frame in its adjusted position.

The casing A is provided with a top a, and

the back of the casing is formed by a p1u-' lows, the said partition being provided with a slit a at'the back thereof, and within the compartment formed above the partition is j ournaled a roller O for supporting the sensitized paper. The sensitized paper extends from the roller over a guide roller 0 arranged adjacent to the slit before mentioned, and downwardly behind the bellows to a feeding mechanism to be hereafter described.

A curtain c is arranged in front of the paper, within the bellows chamber, the said curtain winding upon a spring roller 0 of ordinary construction, and being guided by guides c secured to the side walls of the.

casing.

The feeding mechanism comprises a roller 0 journaled in the walls of the casing transversely thereof, and rovided on its outer end with a handle 0, t e said roller having a ratchet disk 0 secured thereto outside of the casing, and engaged by a pawl c, for normally fixing the roller. Upon the roller are adjustably mounted feeding disks a the said disks com rising'the disk portion pro mi and hollow huiis 0, through which the roller '0 passes, the said hubs being movable on the r0 1 er and retained in their adjusted position by the set screws 0 Other disks c coop erate with the feeding disks a the said disks 0 being journaled on arms 0", which areadjustable on a rod 0 arranged at the lower edge of the bellows, the arms being retained in their. adjusted position on the red by means of set screws 0. Springs 0 are secured to the door a of the casing, and normally press the said roller towards the disks 0, bosses 0 being secured to the inner face of the door by screws 0, to afford a bearing point for the springs.

The feeding disks 0 are of a'circumference, such that a-singlerotation of the roller 0 will feed a strip of paper corresponding in length to a single print, and that part of the side walls a in which is journaled the roller 0 is cut away from the remaining ortion of the side walls and secured to the oor a so that when the door is removed, the roller 0 is removed therewith.

A shelf at is arranged below the bellows, the said shelf extending rearwardly to about the center of the roller 0 and a slit is ar: ranged in the shelf to )ermit the passage of the sensitized paper tierethrough.

A knife D is arranged bulO\V the shelf, the said knife being triangular in shape as shown in. Fig. 3, and being secured to the front of a bar d slidably mounted in guideways d secured to the side walls, the said knife being retained normally in retracted position by a spring d secured to the bar d and to the front wall of the casing. A shaft (Z is journaled in the side walls of the casing below the knife, and arms d are adj ustably secured to the shaft by set screws d", the upper end of the arms being connected by links d with the sliding bar d, the said sliding bar being slotted as at d for receiving the links and the upper end of the arms. A handle is secured to the shaft d, outside of the casing, for manipulating the said shaft to move the sliding bar to cause the knife to sever the paper.

A tray 6 for containing a developing solution rests on the base within the casing at the front thereof, the said tray being provided with an inclined rear wall e, for a purpose to be hereafter described. A device E for receiving the severed sheet and immersing it in the tray of developing solution, is provided, the said device comprising a shaft or roller 0 journalcd in the side walls of the casing,

and having on,its outer end a ratchet disk 6"- engaged "by a pawl 6 the shaft being rotated by means of a crank e secured thereto.

Parallel spaced arms a are secured to the shaft, the said arms being connected together by a cross rod 0'' ad'acent to the shaft or roller, and by a second cross rod e near the free ends thereof. A plurality of fingers e? are pivotally mounted on the rod e, and the front ends of the said lingers are journaled on a shaft e the fingers being connected on the opposite side of the cross rod e by a rod 6 upon which are arranged a 'spect to each other.

plurality of spiral springs a, one s )ring being arranged between each pair of fingers to maintain them in spaced relation with re- Other fingers e" are journaled on the red a a finger e being provided for cooperating with each finger a, said fingers a being arranged below the fingers e gethe'r by front and rear cross bars a, and are limited in their opening movement with respect to the upper fingers by aU-shaped bar 6 having its arms pivoted to the arms e before mentioned.

It is evident from the description, that when the shaft e is rotated in the direction of the arrow'in Fig. 2, that fin ers e e, will be moved towards the rear of the developing tray, and as they engage the inclined rear wall of the tray, they will be elevated by the same, being retained in a substantially horizontal position. When the arms a attain a horizontal osition, the front ends of the fin ers e Wlll en a e the cross bar 6 and a g b D 7 tween the series of fingers directly below the slit in the shelf a, so that when the ex osed strip of sensitized paper is passed ownwardly by the feed rollers, it will be inserted between the series of fingers, and after being severed, will remain therebetween.

When the rotation of the shaft 6 is reversed, far enough so that the front ends of the fingers a leave the cross rod 0 the free ends of the fingers will have'engaged the inclined rear wall of the tray, and the fingers will move into the developing fluid in a substantially horizontal position.

At the rear of the tray eflfor containing the developin fluid, is a second tray g for containing a fixing solution, and means are provided for receiving the developed print rom the tray 0 and removing it to the tray 9". The said means comprises a shaft or roller G journaled in the side walls of the easing, and provided on its outer end with a handle g for rotating the said shaft, a spring g being secured to a pin on the shaft and to the adjacent sidewall for returning the shaft to its original position. The shaft G is provided with parallel spaced arms g", and the free ends of the arms are connected by links g with a cross bar g sliding on guides g arranged on the side Walls of the casing. The bar is provided on its lower face with brackets g in which is journaled a roller g provided with a-plurality of radial pins g,

which project upwardly through slots g in the sliding bar.

The cross bar g is provided with fingers g and the roller g is provided with spring lingers g" for cooperating with the fingers g Stop rods 9 g are arranged at the limits of the travel of the cross bar, and are adapted to The fingers e are connected to-.

be engaged by the pins g before described, to rock the roller g 'to move the spring fingers 9 towards and from the fingers g.

At about. the center of the cross bar g is provided a slot to the end wall of which is secured a spring 9 having an angular bend g at the end thereof, and the roller g is provided with a projection for engaging on either side of the angular portion of the spring when the roller is rocked, in order to retain it in such position.

The relation of the stop rods and the pins 7 is such that when the sliding bar is moved forwardly, the roller g is rocked to bring the spring fingers g into contact with the fingers g whereby to grip' the strip of paper, and

when the stop rod g? is engaged by the pins, the fingers are open, thus releasing the paper and permitting it to drop into the fixing solution.

In operation, the record to be copied is placed upon the support, which is adjusted to proper position, and the reflecting medium is adjusted to properly reflect the image on to the sensitized paper at the rear of the bellows. After the exposure is made, the shaft e is oscillated to bring the fingers of the receiving device into the position shown in dotted lines in Fig. 2, after which the roller carrying the feed disks is rotated one turn, thus moving the strip of paper downwardly so that the'exp'osed portion passes between the series of fingers; the knife is nowo erated to sever the strip, after which the s iaft e is rotated to lower the strip into the developing solution. A cross bar 6 is arranged transversely of the: casing just below the knife, and in position for engagement by the fingers e when the receiving device is in proper position to receive the strip of paper from the feeding device.

After the image has been developed, the shaft 6 is rotatedsufiicient distance to bring the lower'iin ers of the receiving device to the level of the upper edge of the de-' veloping tray, or slightly thereabove, after which the handle 9 of the shaft G is operated to move the sliding bar forwardly, and the stop rod is arranged in such position as to close the fingers g after they have entered between the fingers ofthe receiving device, so that they are closed upon the stri of paper. A reverse movement of the handle 5;, moves the sliding bar to the opposite end together with the.walls of 66 of its travel, and opens the fingers g to permit the, strip to drop into the fixing solution, where it may he left until removed from the machine.

The curtain c is for the purpose of cover-- ing a portion of the strip when it is not desired to expose the entire length within the carrier chamber.

The partition a and the shelf a, form, the casing, a camerachamber, and this chamber, together I portion of the casing,

with the bellows and lens, forms a complete photographic camera. The complete device comprises in effect, a camera having above a receptacle for the roll of sensitized pa er and below a chamber for developing an fixing the print; means being provided for passing ment of the fingers effectually prevents either of these defects.

The fingers of the means for receiving the paper from the feed rollers and immersing it in the tray, are of a length equal to the length of the paper whereby to properlysupport the said paper.
