- 1 This invention relates to coating and printing machines, andv has especial reference to the means for supporting, moving and adjusting certain-'rolls of such machines.

An object of the present invention is the provision of improvements in a machine of the indicated character for bringing certain rolls of the machine into normal cooperative relation to each other, or for breaking the contactual relation of saidrolls so that they may be easily cleaned or washed.

A further object of the invention is the provision of improvements of the character set 'forth above whereby the aforesaid relation of the rolls may be effected from either side of the machine by a simple operation.

A still further object of the invention is the provision of practical means for making the de- 'siredr adjustment of the rolls in combination with the means for moving the rolls into and out of their normal cooperative relation.

With the foregoing, other objects of the invention will appear when the following sp'eccation is read in conjunction with the accompanying drawings, in which- Fig 1 is a vertical sectional view of a portion of a coating or printing machine showing certain features of the present invention, the rolls being shown in their normal cooperative relation.

Fig. 2y isa vertical sectional view showing other features of the invention, the rolls being shown disposed so as to break the contactual relation thereof.

Figs. 3 and 4 are sectional views taken on the respective lines 3-3 and 4-4 of Fig. 1, portions in each view being broken away.

Fig. 5 is a fragmentary detail perspective view.

Figs. 6 and 7 are sectional views taken on the respective lines 6--6 and 'I-T of Fig. l, portions in each View being broken away.

It is toY be understood that the present invention isapplicable to a coating or printing machine in which the coating material, such as a size or the printing ink, is applied to sheets or web material fed through the machine. In the draw- 6 Claims. (ECI. 91-50) 2 by suitable bearings I5 carried by arms Iii` connected with the structure I4 for rocking or pivotal movement by bolts I'I and their nuts and washers. The roll I0 picks up the coating material or ink which is contained in a fount I8 secured to the structure I4. n

The transfer roll II is supported for rotation by bearings I9 carried by arms 29 connected with therstructure I4 for rocking or pivotal movement by bolts 2l and their nuts and washers. The arms 27S are longer than the arms II, the pivotal connection of the arms 2- is below ythe pivotal connection of the arms I1, and the roll I I mounted on the arms 20 is disposed higher than the roll I0.

The composition or applying roll I2 is supported for rotation by stationary means on the structure I4 which means enables adjustment of the roll I2. This roll I'2 serves for applying the coating or printing material to the sheets or web fed through the machine between the roll I2 and a companion roll 22.

The roll II is arranged between the rolls I0 and l2. The arms I6 and 20 support the respective rolls I0 and I I for normal cooperation or for breaking the normal contactual relation of the rolls Ill, II and I2. In the normal contactual relation of these rolls, the coating or printing material is picked up by the roll l0 from the fountV I8, and is transferred by the roll II' from the roll I6 to the roll I2, as indicated in Fig. 1. The arms IE and 2t may be moved to dispose the rolls lili and II for cooperation or said arms may be moved for breaking the contactual relation of the rolls so that the roll I0 is spaced from the roll I`I and the roll II is spaced from the roll I2, as shown in Fig. 2. This enables the rolls to be easily cleaned or washed at the end of a run or whenever desired to remove the coating or printing material and thus prevent any unintentional offset of thematerial.

. The roll I3 is supported for rotation by suitable bearings 23 carried by arms 24 connected with the structure Ill for rocking or pivotal movement by bolts 25 and their nuts and washers. The roll I3 cooperates with a scraper 26 mounted on the arms 24, and serves for the purpose of re.- moving surplus size or ink from the roll I2 and for depositing the surplus into a suitable receptacleI 21 supported on the structure I4 below'the roll 3.

In order to break the contactual .relation of the rolls I0, II. and I2, there is provided means which is manually operable from either side 4of the machine, as follows. A rod 28 for each arm 2,0 has one end thereofv in threaded engagement,

horizontally disposed while the rods move axially The and the arms I6 and 26 rock or pivot o n their connections With the structure I4. Hand levers"` 35 are fulcrumed on the rods 28 respectively in contact With the related abutments 33. Each lever 35 has a cam member 36 which coacts with a cam member 31 forming a part of one section of a casing 38 fixed to the rod 28. The levers 35 are connected to each other by a link 39 Whose opposite ends are pivoted to said levers as at tu.

Upon manipulation of either one o'f said levers 35 the arms 20 will be rocked to the right from When either one 0f the levers '35 is moved in one direction, the' cam members 36 act on the cam members 31 causing the rods 28.150 move axially through the intervention of the casings 38. axial movement of the rods V28y causes the arms 2S to rock or pivot to the right. Each arm 26 has a cam portion 4|` which Aacts on a knob 42 on one end or' a rod 43 connected With each arm I6. Consequently, cam action ofthe portions 4I on the knobs 42 Vcauses movement ofV the arms I6 in response to contactual relation of the rolls, theeam members 36 and 37 are disposed as a result f this' operationv to retain 'the roll VI6 separated from the roll Il, and the l'ol'l H Separated IlI- the 1011 I2; By operating alever 35 linthe reverse direction,

springs 44 cause the return movement of the arms I6 and 26' to bring the rolls intorthe normal cooperative relation for conveying the coating or printing material. The springs 44 surround the ro'ds 43 respectively, and the springs 44 are interposed between Washers' on therods 43;, Each rod- 43 is in threaded eiig'ag'emerit,l as aty 45, lvith a pivot 46 carried by its a-rin- It. The rod 43 is sli'dable a threaded bushing 41 screwed interapivot 48 carried by the relatedV abiit'r'mritI 33,J Thus' Vthe rods 43 are always held? horizontally While' the arms le rock or' pivot by reason of the pivots 46 and: 48. The Washers at the ends' of the' springs 44 are di'spsediri recesses in the' arms f8 andv aloutmer'itsy 33,?and respectively bea-r against the arms i6 and thefbnsh-ings 41. The' recesses in the arms I6 afford clearance for the angular movement oith'e arm-s IE.y Y

the` casings 38. The worm Wheels are secured to the rods 28 while the worms are secured to a shaft turned by a crank on each end at either side of the machine. The rods 43 are rotated equally and in unison by means similar to that described above in connection with the rods 28. No claim is made to the specific means for rotating the rods T28 a`r'1d`43nv, Vsince it is obvious 'that said rods may be rotated for the purp'ses stated above and also for maintaining the rolls I0 and I! parallel to each other and to the roll I2,

Levers 49 are usedfor moving the arms 24 on Y their pivotse 25 to separate the roll I3 from the roll I2. Substantially similar means to that employed in o'niunctin with the levers 35 for moving the aris"2`6is used With the levers 49 forY moving' the arms 24. Therefore, such means used with the levers 49 generally is designated 50 in order 'to avoid needless repetition.
