IPHOTOGRAPHIG-PRINTING APPARATUS.

Specification of Letters Patent. Patented lay 23, 1922 Application filed June 25, 1920. Serial No. 391,601.

To all to komit may concern:

Be it known that I, ROBERT DEMAS MON- INGER, a citizen of the United States, and a resident of Washington, in the county of Washington and State of Pennsylvania, have invented certain new and useful Improvements in Photographic-Printing Apparatus, of which the following is a specification.

My invention relates to improvements in photographic printing apparatus.

The object of the invention is to provide an improved photographic printing apparatus of simple and durable construction, reliable in operation and adjustable to the convenience of the operator and which may be efficiently operated with the exercise of minimum skill 011 the part of the operator.

Other objects and advantages of the invention reside in certain novel features of construction, combination and arrangement of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming part of this specification, and in which:

Figure 1 is a perspective view of the photo with suitable table;

Figure 2 is a transverse vertical. sectional view of the photographic printing apparatus Figure 3 is a vertical sectional view on line 3-3 of Figure 2; I

Figure 4: is a fragmentary side elevational view, showing the presser in retracted position;

Figure 5 is a similar view, showing the presser in intermediate position;

Figure 6 is a similar view, showing the presser in extended position;

Figure 7 is a detail perspective view-of the presser block, presser rollers and associated structure;

Figure 8 is a detail perspective view of the bracket forconnecting the presser block to the presser rolls;

Figure 9 is a detail perspective view of the spring for the link connection;

Figure 10 is a fragmentary plan view of the means for retaining the tiltable section in adjusted position;

Figure 11 is a vertical sectional view thereof;

Figure 12 is a plan View of the printraphic prlnting apparatus associated Figure 13 is a vertical sectional view thereof.

Referring to the drawings, it will be seen my invention contemplates a table 10 which is supported upon suitable legs 11 braced by cross rails 12. The table is provided with a tiltable section 13, pivoted to the the table at 14 to swing vertically whereby the inclination of the tiltable section with respect to the table may be varied as desired. The tiltable section is provided with depending side and end

walls

15 and 16 respectively, and these walls together with the bottom wall 17 define a light chamber. The upper surface of the tiltable section contiguous with the light chamber is provided with an opening 18. The outer surface of the side walls 15 of the tiltable section are provided with a plurality of vertically spaced slots 19 with which a disk 20 eocentrically pivoted as at 21, to the table 10 is adapted to selectively cooperate to thereby retain the tiltable section in adjusted position with respect to the table. It is to be understood that one of such eccentrically pivoted disks cooperates with each side 'of the tiltable section.

A transparent support for the paper and negatives is provided and consists of a sheet of glass 22 which is seated in the tiltable section and arranged to completely cover the opening 18 of the lightt chamber. The top surface of the glass is coplaner with the tiltable section.

A presser, indicated generally at 23, is adapted to coact with the transparent support to properly spread the paper and the negatives thereon to press them firmly thereagainst and provide an opaque backing during the printing operation. The presser is constrained to partake of reciprocatory motion across the transparent support and cannot partake of any other except this rectilinear motion although urged into proper contact with the support. This presser com prises a pair of spaced rollers 23 between which is arranged a presser block 24 which is maintained in desired relation with respect to said rollers by means of four small presser block and which are provided with suitable bearings 27 for rotatably receiving the pintlcs 52h ol" the rollers 223. Bi llexiblc band 29 oi heavy dark canvas extends around the spaced rollers and the presser block. 'lhe ends oi the flexible band are extended through a transverse slot 2&0 provided therefor in the tiltablc section. (lne end of the flexible band rigidly secured, as at 31, to the under side of the tiltable sect-ion while the other end is resiliently secured, as at by means of the spring 33. The resilient securing means including the spring 33 tends to draw the band tightly around the rollers and contact block at all times and in all positions although the contact blocks and rollers are treely movable relative to the flexible band.

Means are provided for reciprocating the presser across the transparent support in any position to which the tiltable section may be adjusted. This means cons'sts ol a transverse shaft llwhich has itsends journaled in bearings 35 secured to the cross rails 12 of the table. Foot operating means, such as treadles 36, are mounted upon the shaft 34; and through a connecting; rod 37 are adapted to impart a rocking movement to the bell. crank 38 which has its elbow pivoted at The bell crank lever includes two spaced members alt) that the upper end thereof is yoked to provide spaced arms 41. The upper end oil each of ti ese arms at connected by the link to the presser having for this purpose one end pivotally connccted as at 4.3, to the press-er block and the other end pivotally connected, as at lel to the upper end of the arm ll.

A torsional coil spring to has its ends extended as at do, and inturned, as at 457. The inturned ends 1?? are respectively seated one in the arm of the bell crank and the other in the link 42. clearly shown in Figures 4-. 5 and (i. This s n'ing tends to swing the link in a counter-clockwise direction toward the arm oi? the bell crank lever and thereby urges the presser into firm and positive contact with the support or with the tiltable section in all positions of the presser on the section.

A transverse bar (4-8 extends between the uppe' arm ll oi? the bell crank lever and a retractile coil spring 40 has one end secured to this bar and the opposite end secured to the table so that it serves to return the means for reciprocating the prcsser to normal position and thus return the p'resser to normal retracted position.

Si n electric light, such as a bulb 50,.is arranged in the light chamber and suitable means is provided for energizing the light. Tl'is means includes a normally opened circuit closer 51 which in its normal. position prevents the electric light from being onergized. The circuit closer 51 includes a push button 52 which is arranged in the path of the transverse bar -18 so that when to be imprinted upon the photographs.

the l ell crank lover has been swung to move the presser to extended position as shown in Figures 2 and 6, the bar l8 will engage the push button 52 of the circuit closer and close the circuit so that the electric light 50 will be energized to effect the printing.

is shown in i igures and 13, identitication means may be associated with the photographic printing a iparatus. This identification means comprises a tape 53 which is arranged to feed transversely across the transparent support The tape 5?) ears suitable identification indicia, such as numbers, indicated as 5 L which are adapted The t: pe is carried by a supply reel and is led across the transparent support to the take up reel arranged upon the opposite side thereol". The supply and take up 1 are suitably mounted in rotatable liicarings and are each provided with suitable operating means, such as a. knob 58. Paul and ratchet mechanism 59 cooperate with the supply and take-up reels to control the feed of the tape. The tape bears against the top surface of the transparent support and an oparpie plate (50 is superposed on the table and support. The opaque plate 60 is provided with a relatively large aperture 6i to acconnnodate the negatives and the paper and with a relatively small aperture (32 with which the identification indicia of the tape is adapted to register. Spring clips (52 are secured, as at (33, to the tiltable section and have their free ends engaging the opaque 1 latc 60 to releasably secure the plate in position.

In operation the paper and i'iegatives are placed by the operator upon the tl'llllSPfllGllt support and the treadles 36 are then depressed. This moves the presser rectilin early from the position shown in l igurc 4i: through the position shown in Figure 4") to the position shown in Figure (3. in its initial. movement the presser engages the paper and negatives and retains them in their proper position. as is indicated in lligure 5 so that any possibility of their being displaced therefrom on the transparmit sup port is precluded. When the presser has been moved to the extended position shown in l ie'urc (3, the circuit closer has been eug'aged and closed by the in'csscr bar 43 and the electric light 50 is energized to e'llect the printing. The ol'icrator after the desired interval releases his foot 'iroin the treadle or treadles and the rctractile coil spring in at once throws the treadles back to their-normal position and moves the prcsscr back to the retracted position shown in Figure 4t.

An important feature of the present in vention resides in the feature of adjustment of the tilting section which may be inclined to suit the convenience ol the operator or the exigencies of the working conditions and in the automatic adaptation of the presser and its actuating and retracting means to the adjustment of the tiltable section, it being noted in this respect that the link 4-2 while permitting'the movement and accommodating the adjustment of the tiltable section is acted upon by the spring 45 to urge the presser into proper contact with the transparent support oi the tilting section at all times. Again the presser does not partake of any pivotal or swinging motion but is constrained to reciprocate across the transparent support. This movement of the presser serves to prevent displacement of the paper and negatives as they are engaged by the presser in its initial movement and held thereby throughout the operation.

If the identification means shown in Figures 1, 2 and 13 is employed, the tape having been fed to proper position so that the de sired identification indicia is registered with the aperture 62 of the opaque plate, the operation herein-above described may be car ried out so that the negative and the identification indicia are both printed upon the paper.

As clearly shown in Figures 2 and 12, the upper surface of the tiltable section is provided with spaced transverse semi-circular grooves or

depressions

64 and 65, respectively, which are adapted to receive the end rollers oi the presser when the same is in extended position.

Having thus described my invention, I'
