Application filed August 12,1916. stun mimosa and claimed.

My invention relates to printing devices for reproducing a multiplicity of prints arranged in symmetrical relation from a single negative.

A further object of my invention is to provide a device by means of which a sensitized plate may be moved with respect to the negative which is held in fixed position so that the design on the negative may be transferred to the plate a number of difierent times; means being provided whereby the plate may be moved slightly from the negative in order to permit its movement rela tively thereto into another position.

i A further object of my invention is to provide a device of the type described, by means of which a sensitized printing plate may be quickly brought'into position and may be stretched so as to prevent buckling of the plate. I

3 A further object of my invention is. to provide means whereby the negative maybe centered before being "placed in its final position in the printing apparatus thereby facilitating the ease of operation of the latter.

A further object of my invention is to provide means which will raise the sensitized plate slightly to permit shifting of the same-with respect to thenegative, while also permitting the plate to be swung back so as to permit access to the inside of the plate if desired.

" Other ob ects and advantages will appearin the following specification, and the novel feat res of the invention will be particularl pointedout in the appended claims.

In carryin out my invention, I provide a base or tabfiz 1 having suitable supports 2. This table is provided with a central circular-opening 3. As will be seen from Fig. 1, the table has extensions 1* and 2 on opposite sides thereof. Run ways 4 which form a track are provided, this track extending over the table, and the extension as clearly shown-in Fig. i.

Referring now more particularly to Figs.

3 and 4; of the drawings, it will be observed that l have provided a pair of negative holders. These negative holders which consist of rectangular plates as shown n Fig. 1,

w on a bevel as shown at 6 in Fig. 4. The cir-' "nular plate 6 is adapted to rotate upon the plate v6 to be easily-turned. Referrin Fig. 4, it'will be seen that a plate of c ear edgesthereof, these V-sha 35.

body portion of the plate 5in the same man-' ner as a circular yalve onits valve seat lubricating compounds being glass 7 is carried by the circular (plate 6 this plate of clear glass being is above a rectangular o ning 8, and projecting above the top of e plate 6. Arranged uponthe plate of clear glass is a negative 9. Thelatter is held in position by means of a slidable clamping member 10, which may be adjusted so as to properl center the negative. From Fig. 4,.1 t will seen that the adjustable dev ce 10 has an n turned flange which engagles the-negative ut tershort 0 "t e upper surface of the negative, thereby rmitting the sensitized plate to be broug t into intimate contact with the negative. 7 v

In Fig. 1, I have shown stop pins 11 disposed on thetable 1, in such position that when one of the negative holders, 5. e., that on the left side of the machine is ushed in toward the center,'it will engage t e stop pins 11, thus bringing the negative exactly to the center of the machine; The table is provided with guide rails 12 at opposite and armembers ranged-to receive V-shaped' frame 13 13 ofa movable frame 13.

has V-shap'ed guide members 13 (see Fig.

10) on its upper edges, these guide members bei disposed at rightangles to the guide mem rs 13. Above the frame 13 is a frame 14, which has..V-sha ped grooves 14 arranged to fit over the guide members 13 so as .to permit movement ofthe frame 14 transversely with respect'to the frame 13.

Theframe 13 isprovided with pinions 13 at the end of av common shaft 13' (see Fig. 9), these pinions being arranged to engage racks 15 at the o posite edges of the table 1. The shaft 13' bearingthe pinions 13 is rovided at its end with a worm ear 16 which is driven by a worm 17, (see ig. 2). This worm 17, it will be observed is feathered to a shaft 18, so as to slide longitudinally with res ct to the shaft 18, but to turn with it. 17", which extends downwardly from the frame 13. The handle 19 is secured to the end of the shaft 18 and is arranged to play over a dial 20 which is perforated so as to permit a ortion of a sprin I in 19 carried by the iiandle, to enter. This forms .a micrometer device for movin the frame 13 with respect to the table 1. oreover it will be observed that as the handle 19 is turned,

used to permit the t is carriedin a' bracket in Fig. 2, the frame 13 will bemoved in a direction parallel to the plane of the sheet.

Referring now to Fig. 10, it will be seen that the frame 14 is provided with a shaft 14', having at its ends inions 14, which engage racks 21, carried y the movable frame 13. The shaft 14' bears a worm wheel 22, whichis feathered to it, in a similar manner as the worm wheel 17 and which is carried between the brackets 22 rejecting from the frame 14. This worm w eel is enga ed by a worm 23 on a shaft 24. This sha 24 1s provided with a handle 25 which plays .over

the dial 26, the arrangement constituting a micrometer device for moving the frame 14 transversely to the frame 13, and in a direction at right'angles to the movement of the'latter.

Secured to the frame 14 are upwardly extending brackets 27 through w ich extend shafts 28. These shafts are rotatable and are provided with cam portions 28 (see Fig. 6) disposed in boxes 29', carried by the frame 29, which as will be observed from Fig. 6, is U-shaped so as to let it extend downwardly through the frames 13 and 14. From .Fig. 6, it will be observed that the boxes 29* on one side of the frame 29 are U-shaped so asto rest on the cams 28. The

--eppos1te boxes 29 are rectan ular for the "will be turned to raise the lower frame 29 bodily and the positions of the frame will always be parallel with one another. The frame 29 is provided with L-sha ed sides (see Fig. 7), the bottom portion 0 one side havin a series of upwardly extending pins 33. hese pins are arranged to enter corresponding openings in the clampin device. See Fig. 7, which consists of a -shaped strip 34 and astraight strip 35, the sensitized plate 36 being disposed between the two and being held in position by means of the screws 37. The'opposite edge of the sensitized plate 36 is held by the clamping device, which consists of an upper portion 38 and a lower portion 39, the upper portion being provided with brackets 40, holding screws 41, which extend through lugs 42 on the frame 29, Winged nuts 43 being provided for moving the clamping device so as to tighten or stretch the sensitized plate and cross head 45 has a hinged connection 46 to one of-the uprights, and has a removable pin 47 which extends through the other upright for holding the cross head in position. The cross head bears a rock shaft 48 having arms 49, which are connected by links 50 to rock arms 51 on the shaft 52 bearing the cam 53. (See Fig. 4). The cam 53 is disposed in a recessed opening 54 of the frame 55 at the upper end ofthe plunger 56 so that when the rock arm 49 is moved by the handle 57 the cam 53 will be turned so as to raise or lower the plunger 56. The latter has an adjustable stem 58 which is secured to a pressure head ,59, guides 60 being provided for this head, as'shown in Fig. '4. The lower portion of the head is provided with a resilient covering 61.

hen it is desiredto raise theframe 29 which bears the sensitized plate 36 in order to inspect the plate, it may: be done by turning a hand wheel 62, see Figs. 2 and 3. This hand Wheel, it will beobserved, is at the end of the shaft 63 which bears drums 64, flexible cables, 65, extend from the drums over the pulleys 66 carried on brackets 67, and are secured to eyes 68 carried by the frame 29. When the hand wheel is turned,

the frame may therefore be raised on its hinges. (See Fig. 6). It will be observed that the bracket 67 is inclined so as to permit the swinging of the frame 29 on its hinges.

Disposed below the table 1 is ailamp 68 which is carried by a post 69 preferably secured to the table by posts 70. In Fig. 1, it will be seen that I have provided a screw 71 at the side of the table 1. This screw is used in connection with the pointer 72 carried by the frame 13, this pointer being capable of being moved relatively to the frame to any desired position by a rotatable adjusting member 73. The frame 13 in turn carries a screw 74 which is used in connection with the pointer 75 of the frame'14. (See Fig. 12).

From the foregoing description of the various parts of the device, the operation of the apparatus will be readily understood. The sensitized plate may be clamped between the clamping members 34 and 38, see Figs/o and 8,prior to its positioning in the device. The cross head 45 may be raised by withdrawing the pin 47 and lifted outwardly on the handle 76 in any suitable manner thereby lifting the pressure head out of the Way. The sensitized plate may now be placed in position by slipping the member 34 over the pins 33, see Fig. 5, and tightening up on the nuts 43 so as to stretch the plate and draw it into perfectly flat condition. The negative is placed in the circular portion 6 of the holder and is secured with registering indicating markers on the negative, and on the top of the body portion of the holder, the circular portion of the holder and the recessed portion may then be brought into proper position by 7 cross head may be adjusted by turning the threaded stem 58. The process is generally begun by making a print in one corner of the plate and when the negative is in proper position, the handle 57 is then thrown down- Wardly thereby forcing the pressure head down upon the sensitized plate and bringing the latter into close contact with the negative. The electric light may be thrown on, and the exposure made after which the light is turned out.

The handle 57 is now raised, thus relieving the pressure from the sensitized plate. The handle 30 is turned in he direction shown by the arrow in Fig. 2 and thus lifts the frame 29 bearing the sensitized plate so thatthe latter is free from the negative.

The handle 19 may now be used to move the frame 13 and also with it the frames 14 and 29 so as to bring the sensitized plate to another position with respect to the negative.

The greatest accuracy can be secured by the use of the screws and the micrometer disks so that the accurate spacing of the dc signs which are to be duplicated on sensitized plates is assured.

Instead of printing on the sensitized metal plate, I may, if I desire, print on to another negative, and to this end, I provide a negative holder 80. 'This is used in connection with the pins 33 carried by the frame 29. To this end, the holder has a flange 80 provided with holes 80* arranged to slip over the pins. The holder is provided with an opening which is covered by the negative 81. At 82 are recesses in the holder, in which are disposed wedges 83, the wedges having resilient material disposed next to the negative. By manipulating these wedges. the negative may be firmly clamped in position. Theoperation of the printing is similar to that already described in connection with the metal plate.

In Figs. 18 and 19 I have shown modified forms with means for holding the sensitized plate in position on the frame 29. (See Fig. 18). The hand clamp 85 is held by means of a screw 86 against the sensitized plate 36. In Fig. 19, the frame 29 has a Z shaped member 29 between which and the support 87, the plate 36 is clamped, the set screw 88 holding the two clamping members firmly together. a

In printing on the negative, it is advisable to use a cloth, such as that shown at 90 in Fig. 4 to prevent light getting to the parts of the plate not intended to be exposed.

The apparatus described provides means for quickly and economically printing large number of similar designs in a very short space of time, and absolutely spacing the designs symmetrically.
