Application filed lta'rch 9,
- T all whom it may concern:
Be it known that I,
a citizen of the United States're'siding at Vinston-Salem, in the count and State of North Carolina, ave invented a new and useful Photographic-Printin Machine, of which the following is a speck fication.
This invention has reference to photo- 'graphic printing machines whereby photographic prints r ay be produced from negatives with rapidity and without the necessity of handling the photographic paper after exposure to actinic light passing through the negative.
In accordance with the invention, there is provided a box of appropriate size and form, housing a light giving unit or units from which light may be transmitted through a negative to affect a sensitized sheet held against the negative, in the usual manner.
Provision is made for positioning the sensitized paper and for numbering such paper,
and at the same time, manipulating a.
. presser board for the negative and paper, and for causing the paper, after being light printed, to leave the negative andgravitate to a protected position, the operation of the structure being in a manner to facilitate the production of the light prints.
The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of -this specification, with the understand ing,-however, that the invention is not com fined to any strict conformity with the showiiig in the drawings, but may be changed 9 andmodified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.
In the drawings,
Fig. 1 is a perspective view of graphic print' a photo- Cnevnnann Snu'soN,
part of the invention. of Forsyth ing machine embodying the invention and showing the presser board ina portion of 1920. Serial No. 364,566.
Figz li is a perspective view of a tiltable or rockable pr nt carrying shelf forming Fig. 6 ma perspectiveview of a clam for holding the negative and also utilizable as art of a mat.
eferring to the drawings, there is shown a a table 1 which may also 'be taken as typical of a bench or other sup ort, and it is to be understood that-the tub e 1 may be carried upon legs 2 or may be otherwise mounted.
On the top of the table 1, there is secured a box or casing 3 her mg a rising front 4 slanting toward the'rear, and in which there is providedan opening 5 at an appropriate height and this opening is'in part closed by a transparent. plate 6 which-ma ordinarily be of clear glass. The glass p ate 6 stops short of the lower edge of the opening '5 and said openin is' then: provided with a 76 rounded edge 7 see Fig. 4-), with the curvature forwardly and downwardly.
Leading downwardly from a point a short-distance abovc'the rounded edge 7 and located on the outer face ,of the frontof the casing is a chute 8,which may be a, metal chute, extended to the table 1 where the. chute opens through a passage 9 into a. re cepta'clelfl, the latter'beingshown as in the form .of a drawer capable of being moved from the table in order that access may be had to the interior of the drawer.
Extending aClQSS the front of the casing Let a point close to but below the'lower edge of the glass plate 6, is a rock shaft 11 carried by ournal bearings 12 secured to the front of the casing and at one end projecting therebeyond and formed into a crank handle 13, which may be done by simply bending the shaft appropriately. Fast on the shaft 11 is a clamp stri 14 having two wings 15, 16 in acute angu ar relation, and near one-end of the wing 16 there is proated as to normally underride the lower edge of the glass pane or plate 6, with the wing 16 in engagement with the'front face of the glass pane close to its lower edge, being there held by .a spring 18 secured at one end to the handle 13 and at the other end to one side of the box creasing 3.
Extending across the front of the casi end rojecting through the opening 5 is a :0 able shelf 19 mounted on trunnions 20 at the ends, said trunnions having jour- 110 the"shelf'19, at its front edge, underrides the-wing of the clamp device 14, the wing serving as a stop for limiting upward 'move-' ment'of the shelf and holding the latter in pro'pei position, and also serving to e the lower edge of the glass late for liun t: in rocking movement of t e clamp into re eased position.-
: Tlib lever 23 pro ects forwardly through a "slot: 26 in the front of the casing to onesideiof the chute 8, so that its frontend is accessible .from the front of thecasing;
1 Seeuredby images 27 to a shelf 27 across -the front bf the'casing near the lower end 0f-lllle "0pBIllI1g5- is a presser board 28 similar to the resser boards customarily employed in p iotographic rinting machines, and in common with ot ier presser boards thepresser board-28 is provided with a facing- 29. of felt or some other suitably soft-- materiaL- r The presser' boar-(128 carries at one side apivoted finger '30 under the control ofa sprin 31, constraining the finger in one a dire 1011 about its'pivot, but yielding to forces tending to move it in the other direction. The the forward end of the rock lever 23 as the presser board is moved from pressing position to open position, butthe finger 30,115 the lever 23 is presseddownwardly, ultimately escapes from the outer end of the lever 23 so that the latter will automatically return to its first position. By providing a stop 32 or other appropriate means in the path of the finger 30, the presser board 2 may be supported in apositiqn,
when open, to provide a temporary table for negatives or paper at a convenient downward slant.-
Fast to and rising from the shelf 27', at opposite sides of the opening 5, are spring c ips 33 designed to engage and hold a pill)- tographic negative 34, which, in the articular showing of the drawings, is in icated as a film which may include several negatives; It .is customary to make prints from films containing a suitable number of negative's without cuttin the negatives, thus facilitating the hand mg of the films in'the printing processi The film 34 is held across the glass plate 6 by the clips 33. In order to introduce the film- 34 the clamp 14 t is brought to carry the wing 16 away from the clam finger '30 is situated to engagelass plate so that the lower edge of the lm'may be readily introduced between the wing'lfi and a the late, after which the 14 is release and the lower edge of the lm is adjusted and clamped along its lower edge against the glass plate, with the partof the film to be printed above the rounded edge 7 o f the opening 5 where leadiug into the chute 8. If it be desired to provide the print with a blank border, a. met or mask 35 is adjusted with respect to the" negative, arid the wing 16, forming the negative -engaging part of the clamp '14, may constitute the lower portion of the mat, the remainder of the matcompleting the terrier-forming part of the mat. The paper, indicated at 36, is then adjusted to the 'mat side of the negative, both the mat and paper being brought against the pin or sto 17 so that the parts are suitably adjuste The lower edge of the paper rests upon the shelf 19 which, at the time, is in the raised or level position. Following these operations the presser board 28 is raised by hand, or otherwise, to engage and hold the paper 36 against the mat 35 and over the negatlve.
During this time a constantly energized electric lamp 37 within the casing 3 furnishes 1i ht, whereby the negative met, when use and paper, may be properly adjusted. The constantly burning light is,
' of course, of non-actlnic quality and .ma
ordinarily be an orange light, since sensitizcd paper of the type ordinarily em loyed for the purpose may be safely han ed in so-called orange light.
\Vithin the casing 3 there is also located another electric light 38 having-suitably high actinic qualitie The electric light 38 may be in the form of a single bulb or a group of bulbs, depending .upon circumstances, and in the case of a group of bulbs the arrangement is such as to spread the light as evenly as may be. One terminal of an electric circuit for energizing the! lamp 38, is carried to the exterior of the casing, as
indicated at 39, and is there in the path of I an electric contact 40 on the. presser board 28, so that when the board is moved to the closed position, the electric circuit is closed between the terminals 39 and 40 as the presser board engages the pa r 36, thus causing the production of actmic light withthis purpose, a numbering device 41 is shelf below the clamp plate and normally i and the presser board at the same time re- 'close'to its lower edge, a chute leading mounted on the presser board 28, so the engaging the latter, and means connected each time the presser board is closed onto a to the shelf and accessible from the front of 2 A photographic rint-ing machine 1pro- 70 board 28 may be actuated. en the board acute angular relation, with one wing nor- 75 28 is moved away from printing-position, mally underrlding the lower edge of the the electric light 38 is cut out of circuit by glass plate, and the other wing in engagethe separation of the terminals 39 and 40 ment with the front face of the glass plate leases t e paper sheet 36, which thereupon the clamp plate downwardly, a rockable gravitates into the chute 8 and ultimately .shelf below the clamp plate and normall into the drawer 10. At the same time the engaging the latter,-and means connected to nger 30 which, when the board 28 'is in t e shelf and accessible from the front of Q the closed position, is above the rock lever themaclune for rockin the shelf, a presser 23, engages the latter and movesit agains'tfboard-for holding a negative ainst the 35 e action of the spring 25, pulling'do\ vn on glass plate, a spring controlle pivoted p the shelf 19 and permlttmg'the print to finger connected to the presser board, and
r0 i to and through the chute 8. a rock lever in osition to be en aged b The mat or mask 35 may be held by the the finger with tie lever and finger related clamping wing 16 and will be so held so to cause the finger to ultimately escape from long as the handle 13 is not manipulated, the lever. this being due to the action of the spring 18. 3. A photographic printing machine prohe operator, therefore, may make as many vided with an. upwardly and rearwardl prints as desired of the negative-by simpl slanting front. having an exposure openi' placing unexposed sheets of paper in pos thenethrouglna hingedly mounted presser 95 tion and closing the presser board 28 onto board movable toward and from the openthe placed sheet of paper. The exposure of ing. a movable support for sensitized matethe' paper-and disposition of the exposed rial, located at the front of the machine, paper are automatic. Consequently prints and connections between the presser board may be made with great rapidity and racand t e movable support a-nd'operable by 100 tically as rapidly as the necessary time of the. presser board when it is swung away exposure will permit. from the opening to discharge the sensitizedhen it becomes desirable to change the material from the support. negative, the lever 13 is manipulated, thus 4. A photographic printing machine proreleasing the pressure of the clamp 14 upon vided with an upwardly and rearwardly the negative and in the case of a film 'conslanting front having an exposure opening, taining several negatives the film may be a pressez: board movable toward and from adjusted to a new posjtionand reclamped, t e opening, a movable support, other than the mat also being clamped if used] In the presscr boa-rd, forsensitized material, order to facilitate the adjustment of the connections between the resser board and lm it is advantageous to have the clamp movable support for disc arging the sensi- 14 temporarily inactive and so there is protized material when the presser board is vi eda latch member 43 which may be moved away from the opening, and means fast to one side of the casing 3 adjacent to whereby tlie support for the sensitized mat e lever 13 so as to hold t e lever in a terial is released to return to the supportposition where the clamp 14 is in the uning position before the opening movement clamped position. of the presser board is completed.
