In Figs. I to XIV inclusive the-movable parts of the ink fountain are shown adjusted and arranged for use in connection with alarger design cylinder denoted by I; while in Figs. XV, XVI and XVII the parts are shown as adjusted and arranged for use in connection with a smallery design cylinder denoted by I*. The impression cylinder, shown in dot and dash outline, is denoted by 2. The design cylinder shaft 3 is rotatably mounted in bearings 4 carried by end frames 5 uprising from a hollow base 6, the inner walls of which end frames form the side walls for the ink fountain bowl. The design cylinder is arranged to be laterally removed through the front of the ink fountain by any well known or approved means, not shown-herein.

The interior of the base 6 forms the lower portion of the fountain bowl. The opening 'I in the top of the base 6 is shown as provided with a suitable screen 8. Ink outlet passages 9 lead upwardly and outwardly from sumps I0 in the bottom of the fountain bowl to the interior of a manifold II secured to the front wall of the base 6. An outlet pipe I2 leads fromthe manifold II to any desired point.

The mechanism for supplying ink to the de.

sign cylinder comprises the following elements:

The hollow inker head includes an outer member I3, an inner member I4, and a nozzle member I5. This .inker head slidably contacts the inner walls of the end frames 5 to form an ink seal at these points for the fountain bowl.

The outer member I3 of the inker head is provided with inwardly directed top and bottom flanges I6 andII. The bottom flange I1 prof jects under and contacts with the vbottom of the inner member I4 of the inker head, said flange having a port I8 therethrough which4 opens to the space between the outer and inner` inker head members and also 4to the ink .supply line, to be hereinafter described. y

The nozzle member I5 is secured to the inner downwardly inclined portion of the top wall of..

the inner member.

The bottom wall of the nozzle member I5 is n provided with a depending lip 22 which overlaps and is spaced from an uprising lip 23 von the top wall of the inner member I4 of the inker head, to serve as a baille for the ink passing through the discharge slot 2| of the nozzle.

Spaced lugs 24 project from the outer wall of the inner member into contact with the -inner wall of the outer member, to provide a manifold comprising upper and lower horizontal passages 25 and 26 and their connecting vertical passages 21. The upperpassage of the manifold opens to the ink discharge slot 2| and the lower passage 26 opens to the ink supply line through the port I8 in the bottom flange I1 of the outer member I3 of the ink head. Screws 28 serve to secure the inner and outer members of the inker headr together.

Ihe inker head is shown as hinged to the base 6 of the fountain to be swung between substantially vertical and horizontal positions, by providing the outer member I3 with lugs 29 pivoted to ears 30 uprising from the top of the base.

The inker head may be provided with a guard member. I3 by the screws 35. The beveled uppery portion of this plate snugly overlaps lthe inner end of the lower ange I1 of the outer member and also the inner wall of the inner member I4l of theinker head. The lower portion of this.

sealing plate 34 is curved at the hinge connections between the inker head and base. A sealing plate spring 36 carried by a sealing plate 31 is secured by screws 38 to a rib 39 uprising from r the top of the base 6. Thisspring 36 contacts the concave outer wall of the sealing plate 34 when the head is in its'closedposition.

The ink supply line includes a supply pipe 40 having a vertical extension 4I which carries the I fixed outermember 42 of a swing pipe joint, the rotatable inner member43 of which pipe joint is provided with an extension 44 secured to the bottom flange I1 of the outer member I3 of the inker head with the bore of the extension 44 in alinement with the port I8 through said bottom flange. j

The axis of this swing pipe joint is in alinement with the axes of the hinge connections between the lugs 29 ofthe inker head and the ears 30 of the base. so that the inker headwhen unlocked, maybe-freely swung to its open and closed positions without disturbing the connectionbetween the ink supply pipe 40 and the interior of the inker head.

`It will be, understood that means, not shown herein, may be provided for receiving the ink from the bottom of the fountain bowl and forcing it into the inker head, Also, suitable means,v

the ink supply before the inker head is swung to its open position.

Means are provided for locking the inker head in its closed or inking position, which means is shown herein as comprising two similar manually operated locking devices, one at each end of the head.

The inner wall of each of the end frames 5 has a properly positioned recess 45. A stud shaft 46 is rotatably mounted to turn in a sleeve 41 threaded into the outer member I3 of the inker .head. The outer end of this stud shaft 46 is provided with a handle 48 for turning it. The inner end of this stud shaft is provided with an eccentric cam disc 49 arranged 4to be brought into threaded engagement of the sleeve 41 with the' outer member I3 of the inker head. A lock nut 5I on the sleeve 41 serves to lock the shaft 46' in its endwise adjusted position. l I

Devices, as swinging stops 52, are provided for limiting the inward movement of the inker head. Upper and lower pins 52* are provided for limiting the upward and downward movements of the stops 52; and upper and lower devices, as spring locks 52* are provided for yieldingly holding the stops 52 in their raised or' lowered position.

The outer member I3 of the inker head may be provided vwith handles 53 for swinging the head to its open and closed positions. A cover plate 54 extends from one end frame to the other and this cover plate is hinged at 55 to the top of the inker head. An inwardly directed sealing strip 56 of suitable material is secured to the free end of the cover plate 54 in position to contact the surface of the design cylinder when the cover plate is swung to its closed position. An outwardly directed guard strip 51 is also'secured to the free end of the cover plate 54.

'I'his cover plate is provided with locking lugs 58 for engagement with sliding latches 59 on the \end.sealing devices to be immediately'described,`

for locking the cover plate in its closed or inking position.

It will be seen that the inner walls of the sealing plate 34, the inner member I4, the nozzle member'l, and the cover plate 54 serve, when the inker head is closed, to form the front wall of the ink fountain bowl.

Means are employed for sealing the top of the fountain bowl beyond the ends of the design cylinder between the inking mechanism and the wiping mechanism, said means comprising two removable end sealing devices.

Each end sealing device is shown as comprising fixed and removable complementary plate members 6I) and 6I the removable plate member lil serving to fill in a cut-away portion in the fixed plate member 6D. ber 6Fl is shown as provided with a ldepending ange 62 having open ended slots 63 through which bolts 64 pass to removably secured the fixed plate member to its end frame 5.

These plate members and 6I are curved and overlap the top side of the design cylinder at its end to the end of the impression cylinder 2. A exible curved contact plate 65 is positioned to Contact the top side of the design cylinder at' its end and this contact plate is secured, as by This xed plate memrivets 66, to the under side of the removable curved plate member 6I. This flexible contact plate 65 with its imposed plate member 5| is shown as removably secured to the under side of the xed plate member B by providing the contact plate with portions which underlap the fixed plate member and are there provided with open ended slots 6l which embrace pins 68 projecting from the under side of the fixed plate member.

The latches 59 heretofore referred to for engaging the lugs 58 to lock the cover plate 54 to each of the end sealing devices, are slidably mounted on the outer wall of the lixed plate member BEI of the end sealing device, by providing the plate member with screws 69 which pass through elongated slots 'l0 in the said sliding latches.

It will be understood that to remove the design cylinder through the side of the fountain the inker head is swung down to its horizontal position resting on the base 6 and the plate members and their cylinder contact members of the end sealing devices may also be removed, if necessary.

A back .trame is Xedly mounted on the top of the hollow base 6, and the inner wall of the back frame forms the back wall of the enclosed fountain bowl. The ends of this back frame snugly contact the inner walls of the end frames 5 to seal the fountain bowl at these points. inner wall of the iiXedly mounted back frame 1| extends upwardly and inwardly to a point adjacent the top of the design cylinder and from thence extends diagonally upward and downward to the top of the frame.` y part of this upwardly and inwardly extended portion of the inner wall of the fixed frame is substantially concentric with and spaced a short distance from the design cylinder.

The wiping mechanism for the design cylinder includes the following elements:

A doctor blade 'l2 is clamped between the members i3, i4 of its holder, which holder is removably secured 'to the free upper end of a doctor frame T5, the lower end 0f which doctor ..1

frame is hinged to a carriage reciprocable on the back frame. This arrangement permits the doctor blade to be swung into and out of its wiping contact with the design cylinder.

The carriage is mounted to reciprocate on the back frame by the following elements:

A plurality of alined brackets 'l5 have base iianges ll secured. as by bolts 1'8, to an upwardly and inwardly inclined portion 19 of the 'outer wall vof the fixed back frame 1|, which upwardly and inwardly inclined yportieri 1.9 is located between a vertical lower portion and an upwardly and outwardly inclined upper portion of the back frame. These brackets 'l5 are provided with downwardly projecting arms having alined bearings `lill for slidably receiving the lower horizontally disposed reciprocating rock shaft 8|. These brackets are also provided with upwardly projecting arms having alined bearings 82 for slidably receiving an upper shaft or rod 83, which is, in the present instance, shown as divided into two alined members.

The doctor reciprocating carriage ,84 is mounted on and reciprocates with the lower and upper shafts 8-| .and 83. by providing the lcarriage with downwardly projecting arms having alined heads E5 embracingT the lower reciprocating rock shaft 8| and also with upwardly projecting arms having alined heads 86 which embrace the two This The upper members of the upper reciprocating shaft 83 and are secured thereto by set screws 8l.

The doctor frame 1.5 is hinged to the carriage 84 by providing the frame at its lower end with alined lugs 88 which are xedly secured by bolts 89 to the free ends of arms 99 fixed to the lower reciprocating rock shaft 8| by set screws 9|.

The means for reciprocating the carriage 84, the shafts 8| and 83 and the doctor frame 15 includes the following elements:

A horizontally disposed drive shaft 92 is operatively connected by gears 53, 94 to the lower end of a vertically disposed shaft 95 rotatably mounted in upper and lower housings 96, 91 secured to one of the end frames 5. The upper end of this vertical shaft 95 is provided with an eccentric 98 on which is mounted in a suitable housing 99 one end of a horizontally disposed connecting rod |00, the other end of which rod ispivoted to a lug |0| on the end of the 'carriage 8 The means for removably locking the swinging doctor frame 15 in its adjusted position to the reciprocating carriage 84 includes the following elements: i

A'pair of hooks m2 are mounted to swing into and out of engagement with their respective members of the reciprocating shaft 83, each hook having a screw threaded shank VS93 which projects upwardly through a pivoted mounting |04 on the doctor frame '|5 into position to be engaged by a. manually operated hand wheel |05 threaded on said shank. These hand wheels W5 may be turned in one direction to tighten the hooks on the shafts, to lock the doctor frame in its wiping position. If it be desired to release the free portion of the doctor frame from the carriage 84 the hand wheels |05 are turned in the opposite direction sufliciently to permit the hooks |02 to be swung out of engagement with the shaft 83, and allow the doctor frame to be swung back to an inoperative position. The shanks |03 Vof the hook-s |512 have flattened portions engaged by a slotted plate |94* of the Vmounting H14 to prevent the hooks from turning when being longitudinally adjusted and swung intov and out of their locking positions.

Means are provided for manually swinging the doctor frame 'l5 when its free portion is released from the reciprocating carriage 84, to serve the double function of adjusting the wiping contact pressure of the doctor blade l2 and also for swinging the doctor frame into and out of its operative position. This means comprises a manually operated hand wheel |06 xed to a shaft rotatably mounted inV suitable bearings |08 in a bracket |99 depending from the reciprocating carriage 84. This shaft |57 is provided with a worm gear connection H0, with the reciprocating `rock shaft 8|', the gear being fixed to the said shaft;

IAdjustable screws I2 are mounted in the doctor frame l5 in position to bear against the heads 86 on the arms of the reciprocating carriage 84 to serve as stops for limiting the inward movement of the doctor frame and thus maintain the adjustment of the doctor blade with respect to the Idesign cylinder. The fixed back frame 1| of the fountain is provided along its top with an upwardly and outwardly inclined seat i3 on which a sealing blade l I4 and its holder |.|5 are movable toward and away from the design cylinder, to adjust the point where the sealing blade |14 presses against the under side A.of the doctor blade 12. Bolts I6 serve to lock the sealing blade holder its adjusted position.

A channel Ill is formed along the top of the sealing blade holder H5 to receive any ink which may possibly pass between the under side of the doctor blade 12 and the edge of its sealing blade H4, and to prevent the ink from passing over the top of the xed back frame 'H and downwardly along its outer wall.

The doctor blade holder may be provided with suitable handles H8 for handling the holder and its doctor blade when the holder is released from the doctor frame 15.

In Figs. XV, XVI, and XVII the parts of the fountain are shown adjusted for use in connection with a smaller design cylinder I In this arrangement the end sealing devices for the larger design cylinder l are replaced by end sealing devices adapted for use with the smaller design cylinder. These devices comprise the xed curved plate member B*, the removable curved plate member 6I and the flexible contact plate 65*. This fixed curved plate member 60* is provided with an outwardly projecting iiange 62* having open slots 63* for receiving the bolts 64. Also, the eccentric cam discs 49 of the locking devices are caused to engage the curved recesses 45* in the end frames 5 when the inker head is swung inwardly to a new position to bring its discharge slot 2| close to the periphery of the smaller design cylinder. Also, the stops 52 may be swung downwardly against the lower pins 52* and there yieldingly held by the lower spring locks 52**. The locking lugs 58 in this instance H in are engaged by the latches 59* on the end sealing 2 member 60*.

When this smaller design cylinder is used the doctor frame is swung inwardly to its adjusted position with its doctor blade T2 in wiping contact with the cylinder, the sealing blade holder H5 being rst adjusted downwardly and inwardly, to move it out of the way of the doctor frame and to properly position its sealing blade H4 for coaction with the doctor blade l2.

While I have shown only two sizes of design' cylinders, it is obvious that the several parts hereinbefore mentioned may be adjusted or replaced for use with design cylinders of varying sizes.

From the above description it will be seen that by hinging the inker head directly to the fountain base it may be swung outwardly to its open position for permitting the lateral removal and insertion of design cylinders of different sizes and also inwardly to different closed positions for coaction with design cylinders of different sizes, and locked in such positions.

It will also be seen that the ink supply line is provided with a hinge joint whose aXis is in alinement with the axes of the hinged connections of the inker head with the base, so that the inker head may be swung to its open or'closed positions without disturbing the connection between the supply line and the inker head.

It will also be seen that by providing the replaceable end sealing devices with removable cylinder contact members these members may be readily removed to permit the insertion and removal of design cylinders of diierent sizes.

It will also be seen that the inker head is provided with a swinging cover plate adapted to be locked to the end sealing devices, said cover plate being provided with a sealing strip in contact with the peripheral surface of the design cylinder between the end sealing devices. It will be noted that this cover plate may be swung outwardly when released from the end sealing devices, without disturbing the inker head.

. It Will'also be seen thatl the inker head is constructed to permit its lower horizontal passage to be open at all `times to the ink supply line and its upper horizontal passage, to be open at al1 times to the discharge slot.

It wil1 also be seen thatl the nozzle member of the inker head may be adjusted to vary the width of the discharge slot to meet different requirements.

The wiping mechanism shown and described but not claimed herein forms the subject matter of my copending application iiled of even date herewith, its Serial Number being 421,433.
