PATRIK ANDERSSON, OF NEW YORK, N. Y.

PHOTOGRAPH-PRINTING MACHINE.

Application filed October 12, 1921. Serial No. 507,244.

To all whom t may concern.'

Be it known that I, PATRIK ANDEnssoN, a citizen of Sweden, and a resident oi: the city oi New York, borough oi' Manhattan, in the county and State oft New York, have invented a new and Improved Photograph-Printing Machine, o'l' which the following as a full, clear, and exact description.

This invention relates to photograph printing machines and has for an object to provide a machine in which the time of cycle of printing operation is decreased to a minimum.

Another object of the invention is to provide a photographers printing machine which is especially designed to decrease the time of cycle of printing operation without diminishing the various adjustments required by' professional photographers.

A still further object of the invention is to provide a photograph printing machine wherein the print when complete is discharged substantially simultaneously with the application of a new sensitized sheet.

In the accompanying drawings- Figure 1 is a side view of a machine disclosing one embodiment of the invention, the same being shown open and ready to receive the print paper. y

Figure 2 is a front view oit' the structure shown in Figure 1.

Figure 3 is a sectional view through Figure 4 approximately on line 3 3.

Figure 4 is a sectional view through Figure 3 on line 4-4, the same illustrating substantially a front view of the frame and associated parts shown in Figure 2.

Referring to the accompanying drawings by numeral, 1 indicates a frame or support which may be of any desired material and which acts to support a box 2 formed of any suitable material. This box is shown as a rectangular box positioned at an angle so that the operator may more readily place the print paper in position. A foot pedal 3 is provided near the bottom of the frame 1 and connected to a rock shaft 4 which when rocked, will swing the arm 5 rigidly secured thereto, said arm in turn being pivotally connected with a link 6 pivotally connected at 7 to a fitting 8 secured to the arm 9. The

' arm 9 is pivotally connected at 10 to the frame 1 and carries fittings 11 and 12 for pivotally connecting the links 13 and 14 to arm 9. Link 13 is pivotally connected at`15 with the fitting 16 secured to the arm 17 car# rying an extension 18 on which a lifter 19 is pivotally mounted and held in a given position by suitable spring 20.

Then the extension 18 is swung upwardly as arm 17 is swung downwardly, lifter 19 strikes against the projection 21 so as to be swung slightly and thereby move out of the path of the lever 22. Before the lifter 19 has been moved out of engagement with the lever 22, said lever is swung on its pivotal supporting rod 23 and has rocked through the arm 24 the shaft 24 sufficiently to move the stop 25 out of the path of movement of the print 26 whereby said print may be slid downwardly into the box or receptacle 27.

It will be noted that the shaft 24 carrying the stop or door 25 is pivotally mounted in suitable journals secured to the frame 28, which frame is slidable along the side angle bars 29 and 30. These angle bars and associated parts are identical so that a description of one will apply to both. The frame 28 carries a lug 31 having an overhanging shoulder 32 as shown in Figure 4 which partially encircles the angle bar 29 so as to hold the parts together. The angle bar 29 extends from the front of the machine to the rear and is journaled on the shaft 23 so that the frame 28 may be readily swung upwardly whenever desired. A short angle piece 33 is secured to the frame 28 above the lug 31 and carries a spring 34 acting against the end 35 of the pivotally mounted brake 36, which brake normally bears against one face of the angle bar 29 and, consequently, frictionally locks the frame 28 in any adjusted position.

By this construction and arrangement, the angle bar 29 may be slid readily toward and from the rear of the machine and may be swung upwardly at any time. The frame 28 is provided with a longitudinal slot 37 through which the clamping bolts 38 and 39 extend, said bolts acting to clamp the centering arms 40 and 41 in any desired adjusted position along the frame 28. These arms are provided with side covering plates 42 and 43 which cover that part of the glass 44 carried by the box 2 which is Inot exposed between the arms 4() and 41. Co-acting with the arms 40 and 41 is a negative holding plate 45 having a central notch 46 and a plurality of side notches 47 arranged in regular stepped order for receiving negatives of diii'erent sizes. The construction is provided to receive glass negatives and after the negative has been properly positioned in one ofthe notches of plate 45, members and4i are moved slightly over the edges of the negative and then the bolts 38 and 39 are tightened. The negative and the paperguiding members 40i and 4l are thenin position for receiving` print paper. A pressure pad 48 is provided which is ormedivitha suitable sott face for pressing against the paper and witha back off anykind, said back being. provided with astrap or Asleeve49,l adapted to slide over the. armv rigidlyseeured vto `shat 5l by ,a set screw or other suitable means. A spring hook 52 ispositioned .as

'i .shown in Figurel to snap.l over the sleeve 49 j,andtherebyloclrthejpad 48 in place. rThese `pads yare,removable that onemay be proyvided oi kproper size to fit between the yarms 40 and 4l when pedal-has been dei pressed. A member 53 is rigidly secured to s'yhaiit 51 and'isy acted upon by -a retractable lspring54for normally'holding the parts as lshown in Figure l. YA n ,armfyis Valsov rigidly secured to shaitt landis ypivotally finountedatlt tothe link l4ivhereby Whenever pedal 3 is depressed, these: members will be moved `for swingingthe ,pads-8 down- Vivardly and againstl 'the print paper placed on the negative supported onthe glass plateV 7 and by the plate 45. As soon as the pedal Bis released,: spring 54 Willmove the parts `back again quickly to theposition shown `in Allligure 4 and said movement ,-ivill cause the `litter 19 toberaised andthereby swing the ,lever Y22 upwardly sufficient distance tto move the stop 25 a.y suflicient. distance to allow the printedpaper to automatically slide down into the receptacle 27 lor in case it should litail to move automatically,lthe operator may givethe same `a slightpush as `he placesfthe fnext vprintpaper in position. .ln this Way tbereis no loss ot time inapplying ander:- posing the print paper andalso by reason. of the adjustment of they arms 4() and.4l,the use of plate and ,associatedparts, there is a minimum loss of time in adjusting the parts to .receive .derent sized negatives;
