Specification of Letters Patent.
Patented Nov. 12, 1907.
Application filed July 3. 1905. Serial No. 268.291.
To all whom it may concern:
Be it known that I, THEODORE A. WsLsrt, a citizen of the United States, of the city of Philadelphia, county of Philadelphia, State of Pennsylvania, post-ofiice address 1221 Market street, have invented a new Printing andDeveloping Dark Cabinet.
My invention relates to improvements in portable printing and developing dark cabinets and the object of my invention is to construct a dark cabinet so that an image may be projected from a negative into the cabinet and-a print thereof made. A further object of my invention is to provide means for developing the print without removing the same from the cabinet; a still further object of my invention is to provide means for focusing the print; and a still further object of my invention is to provide means by which the operator may see the interior of the cabinet and perform the different operations of the work without admitting light which would affect the sensitized print. I
Referring to the drawings Figure 1 isa perspective view of the dark cabinet illustrating my invention;
Fig. '2. is a perspective view of the cabinet looking in the opposite direction from that shown in Fig. 1; Fig. 3. is a vertical longitudinal sectional view as on line 3-3 Fig. 1; Fig. 4. is a vertical sectional view as on line 4-4 Fig. 3; Fig. 5. is a face view of the card holder, drawn on a. larger scale; Fig. 6. is a vertical sectional view as on line 66 Fig.5; Fig. 7. is a rear view of Fig. 5; Fig.8. is a horizontal sectional view as on line 88 Fig. 5; Fig. this a perspective view showing the interior of the cabinet; Fig. 1.0. is a horizontal sectional view as on line 10-10 Fig. 3; Fig.,1l. is a partial vertical sectional view as on line 11'11 Fig. 10, drawn on a larger scale; Fig. 12. is a vertical sectional-view as on line 12-12 Fig. 1'1, and, Fig. 13. is a vertical sectional view as on line 13-13 Fig. 11.
In the drawings 1 represents a rectangular cabinet having upper and lower compartments 2 and 3. The upper compartment is provided with an aperture 4 containing a lens 5. .Upon the outside of the cabinet are securedtelescoping tubes 6, and 7 which aline with the aperture 4 in the. cabinet and direct the .rays of light to the lens. The said tube 6 carries a vertical rod 8 upon which is adjustably mounted'a horizontal rod 9 carrying a plate holder 10 to receiyea negative. The plate holder 10 is adjustably secured upon the horizontal rod 9 by a set-screw 11; set-screws are provided upon the horizontal rod 9,
which stops may be set at different'points upon the horizontal rod so that the negative may be quickly focused adjacent either stop.
An arc lamp 14 is used as a source of light for printing. The rays of light are projected from the lamp through the negative in the holder 10, and the lens 5 Stops 12 and 13 having onto a sensitized surface, preferably a card, mounted in a holder 16 which is adjustable vertically, laterally and longitudinally so that the sensitized card may be properly focused.
The card holder is shown in detail in Figs. 5-45 7 and 8 and consists of a frame 17 having a back 18. An opening 19' is formed at one end of the frame for inserting the card. The saidopening is funnel shaped for the better admission of the card, curved edges 20 and 21 are provided on the frame to form said funnel. The back 18 of the card holder is provided with a slot 22 so that the card may be inserted from the rear in place of the end. -The slot 22 is made with a curved edge 23 on one side, so that the side of the card having the sensitized surface may be slightly concaved to prevent the same from being injured when the card is being inserted or removed.
The frame 17 is provided with grooves 25 and 26 for holding mats in front of the sensitized card. which mats have apertures formed therein which may be of various forms such as ovals, stars, hearts or thelike.
The back of the card holder 16 is provided with a cleat 28 which is held in the slot 29 formed in the depending bracket 30. A nut and screw 31 are provided to secure the card holder at any desired height upon the bracket.
The bracket is mounted on a rack 32 having a slot 33 formed therein through which passes the bolt 34 of the bracket 30. By means of the thumb nut 35 on the bolt 34 the head of the bracket may be clamped at any desired place upon the rack.
Stops36 and 37 are provided upon the rack 32 which may be secured by thumb-screws38 at different points on the rack so that the card holder may be quickly shifted from one focus to another and again brought back to a position adjacent either stop.
The rack 32 is adjustable laterally by being mounted on tracks 39 and 40 at either end of the cabinet upon which the rack slides and on which the rack may be secured by means of the thumb-nuts 41 and 42.
The cabinet is provided with a hood 45 having a nonactinic sliding glass 46 and alsoa sliding cover 47 over said glass. Through the glass 46 may be seen the interior of the cabinet. The end of the cabinet is also provided with an aperture covered by a sliding panel '48 and a non-actinic' glass through which the card holder 16 may be seen for the purpose of focusing.
The cabinet is provided with compartments 50 and 51 having lids 52, said compartments containing drawers .53 and 54 for holding developing chemicals.
The drawers are inserted from the outside of the cabinet as shown in Fig. 2/ By closing the lids 52 the drawers may be withdrawn without admitting light to the cabinet. A door 55, as shown in Fig. 1., is provided to admit quantities of sensitive paper.
- for the entrance of edge ofth'e bag "the bag. The glove is water-proof and light-proof and w o admit a y light' into the bag. 1
down by the weight of ac tinic glass 46 on the to Upon one side of the cabinet is a panel provided with non-actinic glass and a sliding opaque glass 56 over said non-actinic glass, which sliding glass 56 is intended to be removed when it is-desired to allow a greater amount of light into the cabinet.
The top of the cabinet is provided with trays 57 and 1 58 having pipes 59 1eading into the cabinet for supplying chemicals. Aicover 6O fits over the-said trays.
Thelower cor'npartmentof the cabinet forms a tank 61 for receiving waste chemicals which may be poured into the tank through a funnel 62.
The cabinet is provided'with an open panel at one side which is covered bya bag 63 as shown in Fig. 1. The bag is provided with an opening 64 through which the arm maybe inserted to'manipula't'e the parts in the interior of the cabinet.
The opening 64 of the bag 63 is normally held closed by an elastic band 65 and to readily open the same I provide an opening device consisting of two curved members 66 and 67.having connecting pieces 68 pivoted to them and pivoted to each other at the points 69, at which points they are secured to the elastic band 65.' Wires70 also'connect the elastic band and the curyed members 66 and 67. The lower curved member 67 is provided with a footpiece 71 and. the upper curved member is'provided with a handle .72 so that the two members may be separated and thereby open the bag the hand. A hook 73, is also provided on the lower member for securing the same to the under side of a table or the like. i v The bag 63 is provided with a glove 74 formed in one so that both hands may be inserted in A curtain 75 is located adjacent the panel which is covered with-the bag'6f. I The curtain is normally held in the raised position by weights 76 and is pressed the hand which is admitted through the bag. The curtain will, prevent any light entering the cabinet when the hand is being passed through the opening 64 of the bag.
The operation of my invention is as follows: Either a wet or dry negative having an'image thereon is placed -in the plate-holder l0 and the telescoping tube extended to cover the plate holder. .By placing one hand throughthe opening 64 in the bag 63 and the other hand in the glove 74 the curtain is ,forceddown.. Thecard holder is then brought into proper focus, which may be readily done by the operator looking through the nonp of the cabinet or at the end of the cabinet. The sensitized card is their placed in the card holder, the shutter 86 is then opened to allow the, rays of light from the lamp to be projected onto the sensitized card: After the sensitized card has been exposed the proper length of time: the" shutter 86 is again closed and the card withdrawn from the card holderand placed in the developing chemicals and the fixing bath in the drawers 53 and 54. .f By first closing the lids 52 over the compartments 50 and 51 the said drawers may be withdrawn from the outside jofj'the cabinot so that the card mayibelremoved. .The lids 52 will ,prevent the light from entering the interior of the cabinet and injuring the unexposed sensitized cards when the drawers are being removed.
