An object of this invention is to providea means for making prints of the continuous tone type from printing plates, particularly of the swelled gelatin type, and of finishmg these prints so as to give them more of the brilliance, depth and definition of contact photographic prints. a 1

Another object is to provide a method of and apparatus for finishing prints made by any one of a number of well known methods so as to" give them a luster and depth oftone such as is now possessed only by photographic prints. ,7

Another object is toprovide mechanism whereb prints may be made from a plate, prefera ly of the continuous tone .type, and the images transferred as by-means of a rubber blanket to a sheet of paper, this sheet preferably being'in the form of a roll so g0 that'it may be passed continuously through another part of the mechanism for finishing.

These and other objects as will hereinafter appearare accomplished by this invention which is fully described in the follow-' ing'specification, and shown in the accompanying drawings, in which- Figure 1 is a front elevation of the forward end of the printing mechanism showing the carriage in position to start back on the return trip; 7 e

The printing mechanism consists essentially of a'stationary frame A upon'which is movably mounted a carriage B, which is propelled backand forth by means of a motor C, through a gear mechanism shown in Figs. 2 and 7. \Vhenthe carriage is moved from the position shown in Fig. 1 at the front end of the m chine to the rear end of the machine, it is raised by meansof mechanism which will later be described. As it approaches the rear end of the machine, the carriage is lowered and stopped, after which it is propelled forward again tothe position shown in Fig. 1. As it starts forward it passes .over

the printing plate D (Fig. 4) which has previously been inked, the carriage carrying a Frubber blanket which picks up the image from the inked plate D, and, as the carriage moves toward the front end, deposits this image upon the upper face of the paper strip E. i Y i Referring now to Fig paperi E is fed to the left, while the carriage makes its return trip toward the; right in Figs. 3, 4 and 10. On leaving the machine, as shown in Fig. 10', the'paper strip E makes a 100 as it passes into the treating mechanism?" (Fig. 11) and from here the strip of paper E passes through the drying frame G emerging at E ,-and passes up through the moistener H, and from here it passes on to the continuouslydriven enameling drum J, the paper strip leaving thedrum J at E, and then passing on .to acutter, roll, or the like (not shown); If desired,-a strip of cloth K A may be applied to the back of the strip of paper while on the enameling drum.

With special reference to Figs. 1 to 10, the

. 10, this strip 6f main frame A supported upon end frames and 16 and a center frame 17, and has horizontal rack bars 18 and 19 which extend throughout the length of the machine. Side rails 20 and 21 lie outside the rack bars and are guided thereon by means of shoulder screws 22 which operate in vertically disposed slots 23, as is shown in Fig. 2. The purpose of this is-to permit a small amount of vertical movement of the side rails for the purpose of raising and lowering the carriage B, as will later be described. The side rail 21 is flat on top, while the rail 20 is provided with :a central ridge 20, as shown in Fig.

2, to engage the grooved rollers ofthe carriage'and of the blanket roll in order to prevent lateral movement of. the same with respect to the plate and to the sheet of paper thereby providing positive registration.

Propelling mechanism The motor C continuously drives :1 shaft 24 through a worm and worm wheel enclosed 'within'the casing 25. The shaft 24 has a spur gear 26 keyed thereon which drives an idler 27, which in: turn meshes with a gear 28- which is keyed on a shaft 29 which is journalled insuitable bearings in the carriage B.

The shaft 29 has an'idler gear 30 journalled thereon. The gear 30 is provided with adental clutch 31 which is adapted to be engaged by a complementary dental clutchmember big driving gear536 on a shaft 37 which carries the rubber blanket 38, as shown in Fig. 5. A spur gear 39 similar to the gear 36 is carried on the other end of the shaft 37, these gears meshing with the'longitudinal racks 18 I and 19 respectively. The shaft 37 is suitably journalled in bearing blocks 40 and 41,

Figs. 1 and 3. These bearin trolled b one'at each end of the shaft 37, as shown in blocks are movable up and down in suita 1e guides in the carriage B, the hei ht of the shaft 37, and hence the height 0 the blanket roll 38 with respect to the carriage B being conmeans of mechanism under the control 0 ahand wheel 42. s This mechanism is well known in the art of printing 'machines, and hence is not described in detail.-

Thus it will be seen that so long as the Cam 35 permits the clutch member 32 to engage the clutch 31, the motor driving through the shaft 24, the gears 26,27, 28, 30 and 31 will propel the carriage B'and all of the parts carried thereby in a forward direction, that is, toward the right as shown in Fig. 1.

The reverse motion of the carriage is accomplished through the .gear 3 9 on the shaft 37, this gearmeshing with an idler gear 43- running loose on the shaft 29, this gear in turn meshing with a gear 44 loose on a shaft 45, which is suitably journalled in the carriage B and whichhas keyed thereon a. spur gear 46 which meshes with the idler 27. A

clutch member 47, similar to the clutch member 32, is splined upon the shaft 45, and has a spring 48 which urges it into engagement with a dental clutch 49 on the face of the idler gear 44. The clutch member 47 is controlled by a pin 50 which is axially mounted in' the hollow end of the shaft 45 so as to be operated by a cam 51 which is carried upon the side of the carriage B, and which later wilPbe described.

Thus, with the parts in the positionshown in Fig. 7 the clutch member 32 is disengaged from the idler gear 30, while the clutch member 49 is in engagement with the idler gear 44. This causes the carriage B to be propelled in a reverse direction, .that is toward the left as shown in Fig. 1. 4

Raising and lowering mechanism brackets 52 and -53upon which are mounted rollers 54 and 55 respectively. Wedges 56 and 57 are mounted to slide horizontally upon brackets 58 and. 59 which are carried by the ably connected by a turn buckle, 62 which is cylindrical in form. A block 63 is rotatably The movable side rail 20 is provided with main frame A. These wedges are connected bv. means of rods 60 and 61, which are adjust-' mounted on the turn buckle 62, and has a v screw 64 by which it is adjustably secured thereon. A link 65 is connected at one end to the block 63 by means of a cap screw 66, and at the other to an operating lever 67 which is pivotally mounted at 68. The purpose of this lever will later be described.

. A link 69 is connected to the cap screw 66, preferably by means of a threaded eye 70, the

other end of the link 69 being connected with a lever 71 which is pivotally-mounted on a shaft 72, which is suitably journalled in the main frame A. The upper end of the lever 71 carries a dog 73 which is 'pivotally mounted thereon by means of a pin 74. This dog is normallv urged upwardly by means of a spring 75 upon a rod 76 which is pivotally mounted at 77 on the dog 73. The rod 76 is screw threaded and carries adjusting nuts 78 which limit the upward movement of the dog 73. A pawl 79 is pivotally mounted at 80 upon the carriage B and is normally pressed down by means of a suitable spring 81. These parts for raising and lowering the carriage are duplicated on the back of the machine, as will be seen by comparing Figsll and 3. I

Thus it will be seen that, as the carriage ment of the cam lever 35.

moves to the right, the pawl 79 will ride over shown 1 and 2 in which the carriage the shoulder on top of the dog 73 thereby causing the two to engage, as shown in Figs. 1 and 2. As the carriage now starts back, the pawl 79 draws the dog 73' with it. As the pressure between the two increases the dog 73 is turned about the pin 74, compressing the spring 75 until eventually the two disengage by a gradual wiping movement. This accomplishes three things: first, it eliminates all the back lash in the gear train between the motor and the big gears 36, 39 and the racks 18 and 19; second, it draws the lever 71 to the right, as shown in Fig. 2, thereby movin throng the agency of the links65 and 69 thus lifting the rollers 54 and 55, and hence the side rail-20, which in turn'lifts the carriage; and third, it draws the lever 67 to the right, as shown in Fig. 2 thereby setting it ready to be operated for lowering the carriage as it approaches the end of its next rearward movement. a

Reversing mechanism The cam levers 35 and 51 are mounted upon pivots 35 and 51" respectively on the front and back of the carriage, and have downwardly extending arms 35 and 51 adapted to contact reversing stops adjacent to the carriage. Referring now to Fig. ,2, the stops 82 and 83 are adjustably mounted upon a rod 84 which is attached to the side rail 20. Similar stops are" placed upon the back of the frame 'toengage the cam lever arm 51". In order to hold the cam 51 in the engaged and disengaged positions andnalso to cause it to pass quickly from one position to the other, I have rovi'ded the cam lever 35 with a'springtogg e consisting of a rod 85, which is slidable in ahinged mounting 8.6 and pressed outwardly by means of a spring 87. The toggle rod 85 also limits the swing of the cam .lever-35 in both directions. As this toggle swings past dead center, it throws to the opposite side, insuring a full move This same arrangement is provided for the cam lever 51 on the back of the machine.

On the front side of the carriage B is a roller 88' which is mounted upon aba'r 89.

' which is adjustably secured to the side of the carriage by means of ana 'justing nut 90. The roller 88is adapted to engage the lever67, and to force the lever substantially to the position shown in Fig. 2. A. similar roller 91 is located on the back of the machine, as shown in Fig. 3, and is similarly adjustably' mounted on the side'of the carriage, and engages a lever similar to the lever 67. i

The operation of mechanism for stopping and reversing the travel of the, carriage and of raising and lowering it is as follows: Assuming that the parts are in the position the blocks 56 and 57 to thegrigh t' the driving motor C. At the same time the pawls 79, one at each side of the carriage, have somewhat overrun the dogs 73, the springs 81 and 75 yielding to let these elements pass each other. The stop'83 on the back of the machine is set slightly forward ofthe stop 83 soas to insure the clutch member 32' being completely disengaged before the clutch member 47 is permitted to engage. As the carriage travels forward, therefore, the cam lever arm 51 strikes the stop 83, shifting the cam lever 51, and releasing the pin 50 and permitting the spring 48 to force the clutch element 47 into engagement with the gear 44. The motor, acting through the gears 46, the shaft 45 and the gears 44, 43

and 39 begin propelling the carriage in the reverse direction.

As vthe carriage moves back the pawls 79 acting on the dogs 73draw the levers 71 to the left, and causethem to lift the carriage through the side rails 20 and 21, as has been previously described. At the same time the dogs 73 hold back on the carriage so as to take the back lash out of the gear train, so that the rearward motion of the carriage is very smooth and free from vibration and jerkiness, such as would otherwise occur. Also moving the lever 71 to the left moves the upper end of the reversing levers 67 to the right as viewed in 2, thereby setting it ready for the lowering operation as the carriage approaches the rear end of the machine on its next rearward movement.

As the carriage approaches the rear -end of its movement, the cam lever arm 51 engages a stop on the back of the frame. This stop is not shown, but is set a little in advanceof stop 82 ofFig. 3 so that the cam lever arm 51 will strike it causing the cam 51 to force the pin 50 inward, thereby disengaging the clutch member 47. For an instant both About t iissame time the roller 88 strikes the lifting lever 67, while the roller 91 on the back of the carriage strikes a similar lever. As the carriage continues to move backward its inertia is utilized to force these levers back so as to move the wedges 56 and 57, thereby lowering the side rails 20 and 21.

. and nut 95 limit the extent of its'swing in a the operation, as previously described, is repeated.

In order to insure that the backlash is removed from the gear train on the forward movement of the carriage, there is provided a stabilizer 92 whichis pivotally mounted at 93 on the side of the carriage B ='(Fig. 3), this braking member having a spring 94 which forces it downwardly, while a bolt downward direction. The stabilizer 92 is adapted to pass up over a pin 96 on the extreme rear end of the main frame as shown in Fig. 2. The pressure thus exerted is Sam; cient toh old the carriage back until ubstantiallyali the back lash is removed rom the 2 .train of gears, after which the spring 94 yields sufliciently to permit the carriage 'to start forward.

Thus it will be seenthat on its rearward movement the carriage is lifted sufliciently to I ment sowthat the blanket roll 38 can then,

cause the blanket roll 38 to clear the paper E and plate D, the carriage then being lowcred when at the extreme rear end of itsmovemake contact with the face of plate D on its 'next forward movement transferring the image thus received to the paper E at-a later hence the .amount of' themoi'stening liquid fed to the moistening roller 95.

'Ink is supplied to the plate from ,an ink reservoir 110 which is carried on suitable supports from the carriage B, and has a roller 111 which dips into the ink in the reservoir 1-10. A ductor roller 112 is carried upon a lever 113 which is pivotally mounted at 114 and normally lies in contact with a large ink roller 115.

The upper end of the lever 113 actuated by a cam 116 on a shaft 117 which is driven by means of a friction roller 118, which is v in contact with the friction plate 104. The

friction roller 118- is movable in and out along the face of plate 104 by means of an adjusting screw 119. Thus the frequency with which the ductor 112 ,makes contact with the roller The ink on the large ink roller 115 is then fed through a; series of distributing rollers 120 to the plate inking rollers 121 and 122,"

which have gears'onthe front side of the malarge chine-meshing with the rack 18. The inters mediate roller 123 has a gear (not shown) 95 meshing with the rack 19 onthe back of the machine. 122 and 123 are suitably journalled in bearings in an auxiliary; frame carried by the The various rollers 115, 120, .121, v

, mainframe B, and the whole train of ink T00 distributing rollers is driven. by the geared rollers 121, 122 and 123, the diameters of these rollers being coincident with the pitch'. 4 diameters of the gears to which they are attached, This is true also of the roller 95, which has a gear driven by the rack 18. r

Moistening and inking of the printing plate D is accomplished onthe forward mo- 1 tion of the carriage B ju after the rubber blanket roller 38 has passedover the plate 0. D removing the ink image therefrom. It is necessary, however, to protect the paper roll E from themoistening and inking rollers 95 to 121 etc. To do this,(a. relatively thin metal plate 124 is provided at the side of shaft 24 acting through the chain 102 drives each of the racks18 and 19, this plate serving a shaft 103 which carries a friction plate as a track upon which the r ller 121 104." This friction plate has a'friction roller and 123 roll in order to lift them above the 105 splined upon a shaft 106, the roller 105 surface of, the paper E. When. however, the being moved in and outon the friction plate carria c has advanced a little further to the 104 by means of ascrew 107. The shaft 106 right 1t is lifted bodily, as has previously carries cam- 108 which is adapted at each been described,so as to carry these rollers .revolutionto engage theouter end ofthe cam entirely clear. of both the paper E and the 7 follower 109, and to force it outwardly thereplate D, and they remain so elevated while by movi the ductor out Jofcontactwith the the carriage is traveling back and until. it is roller 98 and into contact with the nioistening again lowered. These gears are still in conroller95. b v I h tact'however with the plate 124.

' 1 It )wilI thus be seen that y movin t e I v friction roller 105 toward the center o f the at??? feedmg W plate 104 the speed of the shaft 106 will be The paper upon which the prints are to be 3 stage in this same forward movement.

Mqz'stening and inking Referring now to Figs 1 and 8, the moistening mechanism consists of a moi'stening roller 95 with a series of moisture distributing rollers 96. Moisture is obtained from a tank 97 which has a roller 98 dipping into a suitable moisteningliquid which is used to moisten the plate. The roller 98 is mounted upon a" shaft 99. which is driven by means of a chain 100 from the shaft 24. A ductor roller 101 serves to carry moisture from the roller 98 to the moistening roller 95.

The mechanism for intermittently actuating the ductor roller is as follows: The shaft .madeis in the form of a roll 125 which is carried upon a shaft 126, which is rotatable in a notched sup ort 127 attached to the frame member 17.; his shaft carries a friction wheel 128 over which passes a friction band 129 which is secured at each end to the support 127, the opposite end passing over the.

wheel 128 and carr ing a weight (not shown) The paper strip and-131 and forward over a table 132, thence under the tension roller 133, and over the feed roller 134, from which it emerges as the paper. strip E which then passes into the treatin and enameling apparatus Fig. 11.

The fee ing of the paper strip E is 10- complished by the feed roller 134 which has a gear 135 which. meshes with a. gear (not shown),'associated with the sprocket 136. A ratchet also (not shown) between the gear 135 and the roller 134 drives the latter only when the sprocket 136 is turned in ,a clockwise direction. A chain 137 passes over the sprocket 1,36 and carries a weight 138, the opposite end of the chain being secured to a rod 139 which is slidable in a tube 140. The

. tube is cut away along one side at 141, and' a knob 142 pro'ects out ,through this cut away portion. A nger 143 is carried by the carriage B, and is adapted to engage the knob 142, which is adjustably mounted upon the rod 139. p

Thus as the carriage moves toward the right, as shown in Figs. 3' and 9, the finger 143 engages the knob 142 and moves it to the right, thereby turning the sprocket 136 to the right, While the feed roller 134 is turned to the leftby means of the gear 135, thus propelling the paper strip E to the left. As the carriage" returns to the left the finger 143 moves to the left, permitting the rod 139 to move also to the left as the knob 142 is held in engagement with the finger 143 by the weight 138.

of the rod 139.

the latter remains stationary during this backward movement of the carriage B and Thus it will be seen that a mechanism is provided wherebyan ink image can be transferredfrom a plate to a sheet of paper with a minimum .of injury to the plate, so that thelatter may be of the swelled gelatin type,

- over said plate. x L The paper strip E is thus fed through the printing) machine intermittently emerging and a great many prints may be taken therefrom without material injury-thereto. This is due to certain inherent qualities in the machine, one of the principal features being the rubber blanket whic asfa rolling action therefrom as shown in Fig. 9, to forma long loop E, the other end ofthe loop leading into the treating and drying mechanism, shown "in Fig. 11. From hereon, as will presently be seen, the paper strip is drawn continuously.

passes around rollers 130.

Due to the ratchet action be-; tween the, sprocket 135 and the feed roll 134 b oating and enameling meckanism- 7 Figs. 11 and 12 show the coating and drying mechanism, while Figs. 13 and 14' show the enameling drum. The coating and drying comprises a frame 145 to which is attached a drying frame or housing 146 of sheet metal, or the like, having-as'urface 147 over which the paper strip E passes. The surface 147 is shown as'curved so as the better to prevent the edges of the paper curling up as it dries. Agas burner or other heating element 148 is placed within the sheet metal housing 146. r

' The frame 145.carries a suitable tank 149 rwhich contains a liquid coating which is to be applied to the printed face of the paper which have been made by the machine previously described are preferably of the con-.

-- tinuous tone type, it will be understood that they are not necessarily limited thereto, as half-tone prints may also be made and coated other light sensitive thereby. The machine in the process previously described is intended primarily for use with collotype or swelled gelatin plates, but

by photogra vure, transfer processes or photographing down processes and the like, and

prints made by any of these processes may be surfaced and enameled by the mechanism which is now being described.

'halftone plates can be used, also plates made) The paper strip E which has previously been printed by any of the foregoing processes or in water colors may passed up under the roller 150, over the roller 151, and down under the roller 152, which submerges the entire width of the paper strip in the gelatin bath'149. For this purpose the rollor 152 isconsiderably narrower than the -width of the paper strip E; the gelatin bath due to capillary attraction-will permitthis strip to be submerged some distance beneath its surface without overflowing upon the back thereof. 1 A

As the paper stripE with its surface film of gelatin emerges from the bath 149, it

passes up over the .roller 153 and slides around the back 147 of the drier G emerging at the bottom at a dried strip E which passes over a. series of rollers and eventually reaches the enameling drum J; shown in Figs. 13 and 14. This is mounted upon a frame 154, and is driven very slowly, preferably by means of worms and worm wheels within the housings 155 and 156. Theworm shaft 157 con-f nects with a-mt0r or other suitable source of power (not shown). To reach the drum J, the sheet of coated and dried paper E passes under the roller 158, thence up over the roller 159, and down under the rollers 160 and 161. As the strip passes under the latter rollers it is brought into contact with a surface of alcohol andwater or other suitable moistening medium which would put the coated surface of the paper in condition for enameling. f Asthe paperstrip emerges from the back of the moistening medium H it asses up over the roller 162, and over the rol er '163, which latter forces the treated surface of the paper firmly into contact with the cylindricalsurfaceof the enamgling drum J. A suitable distance is provided between the roller 161 go andthe roller 163 to permit the liquid in the bath H to partially soften the coating on the paper so that when it is brought into contact I with the highly polished surface of the drum J I it will 'make intimate contact therewith the g5 roller 163 actingas a squeegee roller to force the moistened surface of paper firmly into contact with the polished surface of the drum.

For some purposes it is desired to provide the stri of aper with a backing of cloth, or the li e. 1 uch a backing of gummed cloth -K ma be provided by takingit from the roll of cloth 164 and passing 1t up over the roller 165, down under the roller 166 which dips the clothinto a. bath. of liguid 167, thence up 'over the roller 168 which orces it firmly against the back of the paper strip. The. rollers 163 and 168 are provided with adjustable means whereby the pressure applied. thereon may be varied to suit conditions.

The enameling drum J slowly revolving in a clockwise direction, as shown inFig. 13, and the moistelfer in the-bath H, preferably alcohol and water, has had time to evaporate by the time the paper strip passes around with the drum to the stripping roll er 169. This roller serves to pull the paper strip off the face of the drum, after which the enameled and dried paper strip E passes up over the roller 170, and out betweenthe rollers-171 and 172. From here the paper strip passes on to atrimmer, or the like, where the prints are trimmed and separated. By this means any desired surface may be 7 obtained, such as matte, semi-matte, or gloss,

the degree of gloss depending very largely upon the amount of coating material applied to the strip and also upon the paper ,surface. Thus it will be seen that a very simple and 1 eflicient means is provided for enameling the surface of prints of various kinds soas to give them the gloss, depth,.and brilliancy of contact photographic prints.
