An improved inking mechanism embodyinvention have been omitted from the drawings.

In the form shown, the improved inking mechanism includes an ink applying roller journaled in a, reciprocable carriage and adapted to be rotated and inked by a transfer roller which receives ink from a supply roller.

The transfer roller is carried by an improved form or framewhich is detachably secured to the reciprocable carriage. A distributing roller is arranged in contact with the transfer roller and is continuously reciprocated by improved mechanism on the frame.

'In order that the ink applying roller may cease rotating as it approaches printing'position, improved mechanism is provided for stopping the frame abovethe lowermost position of the reciprocable carriage so as to dis engage the ink applying roller from the rotating transfer roller.

In the embodiment illustrated, the inking mechanism is applied to an addressing machine comprising a pair of supports or brackets 1 mounted on ahorizontal bed 2 having a pair of spaced rails 3 and4 forming a guide wva for-s11 ortin aseries ofsten 'l 5 h' h with the transferring roller as it approaches y pp b 81 S W 10 are fed step-'by-stepthrough the machine by. means of an endless conveyer, not shown, so as to be operated upon by the printing mecha-. nism and by various other mechanisms, notv shown.

J ournaled in the supporting brackets 1, is a hsaft 6, which is adapted to be driven by suitable mechanism, not shown.

Mounted on the rail 3 is a guide 7 for guiding the endless conveyer, not shown, which feeds the stencils through the machine. A; portion of the guide 7 as shown in Figs. 3 'cIIld'4ySQI'V6S as a stop for limiting the downward movement of the transfer roller, as hereinafter described.

In the form shown, the improved printing and inking mechanism includes an ink applying roller 8 journaled in a reciprocable carriage 9, which supports a movable frame 10, on which is mounted a transfer roller 11 and distributing mechanism 12 for transferring a uniform coating of ink to the ink applying roller from asu'pply' roller 13, which is fixed on the rotatable shaft 6.

The mechanism for rotating and inking the supply roller 13 is not a part of this invention and has been omitted from the drawings.

In the Specific form shown, the carriage 9' ccmpris'es apai'r of end members 14 and 15 connected to a cross brace 16 having an openmg 1'? for receivingil'iebolt of the mechanism,

not-shown, which oscillates the carriage for moving the ink applyingr'oller toward and from thestencils. The carriage oscillating meehanism is shown and described in the cope'nd ingi application, Serial No. 348,782, filed March 21, 1929'.

Formed'on the endmembers 14and 15, are bosses 18, which are journaled on bushings 19 on the shaft 6, which forms the pivot on which the carriage 9 oscillates.

The frame 10'is shorterthan the carriage 9, so-as to fit between the en'd'members 14 and of the carriage. In the form shown, the

frame 10 comprises a top plate 20- integrally formed on a pair of end brackets 21','-which are bifurcated at their outer ends, as shown at 22, so as to be adapted to fit over the shaft (1 atrespectivel opposite ends of the supply roller 13. e shaft Gserves as a pivot on whichthe frame 10 oscillates.

Formed onthe end brackets 21, are openings23, in which is supported a fixed shaft 24,011 which thetransfer rollerll is rotatably supported.

The endsof the shaft 24 project outwardly beyond the brackets 21 and are provided with flat bearing surfaces 25 for engagement with levers 26, which are arranged to normally urge the fralne 10 into position for pressing the transfer roller 11 into firm contact with the supply roller 13 and ink-applying roller 8'.

The levers 26 are pivotally connected to the end brackets" 14 and 15 of the carriage b pins 27. Formed on the lower ends of t 10 levers26, are'shoulders' 28", which engage the bearing surfaces 25 of the shaft 24. The" upper ends of the levers 26 are connected to springs 29 anchored to the cross brace 16- of the carriage.

lVith this improved construction and arrangement of parts, the levers 26 yieldingly urge the roller 11 into effective contact with the rollers 8 and 13 and also detachably secure the frame 10 to the carriage 9.

In the embodiment shown, the improved distributing mechanisms 12 includes a roller 30 loosely mounted on a shaft 31, which is.

supported in elongated openings 32 formed in the brackets 21.

The shaft 31 is'urged downwardly by means of springs 38, which yieldingly hold the roller 30 in ell'ective contact with the transfer roller 11. The lower ends of the springs 83 extend through the shaft 31 and the upper ends thereof are secured to screws 34 secured to the top plate20.

The distributing roller 30 is'rotated by con tact with the transfer roller 11 and is re ciprocated axially relative to the roller 11 by means of a sleeve member 35 embracing a 130- tatable shaft 36, whichis journaled in open in'gs 37 formed in the brackets 21.

Formed on one end of the sleeve 35, is a bifurcated arm 38, which slidably engages an annular'grocve 39 formed in the distributing roller 80. Formed in the sleeve 35, is a radially disposed slot 40, in which is seated a pin 41. The outer end of the slot 40 is covered with a removable plate 42 having an aperture 43 through which the pin 41 may be lubricated.

The inner end of the pin 41 rides in a race 44, which is formed in the rotatable shaft 36; In the form shown, the race 44 comprises a pair of oppositely disposed spiral grooves communicating with each otherso that, upon rotation of the shaft 86, the pin 41 travels from one spiral groove-to the other and causes a'reciprocation of the sleeve 35 and distributing roller 80.

The shaft 36 is geared to the transfer roller 11 by gears 45, 46 and 47. The gear'45' is fixed on the shaft 36 and the gear 46 is jour-' naled on a stud 48 mounted on one of the end brackets 21 of the frame 10. The gear 47' is fixed on a hub 49' of the transfer roller 11;

r In order to permit the ink applying roller 8 to cease rotating during. the printing. operation, it is necessary to disengage the rollers 8 and 11 before the ink applying roller engages the stencil.

The mechanism for disengaging the rollers 8 and 11 includes a pair of arms 50 mounted on the frame 10 in position to engage the stop 7 for limiting the downward movement of the frame 10 independently of the carriage 9'.

In order to permit adjustment of the arms 50 relative tothe stop 7, they are pivotally secured to the frame brackets 21 by pins 51.

One end of each of the arms 50 has a shoulder 52 adapted to engage the stop 7. The other ends of the arms 50 are pivotally secured to links 53, which are adjustably secured to the top plate 20- of the frame'by' screws 54,

having knurled nuts 55 arranged to shift the links 53 longitudinally'for securing the desired adjustment of the arms 50.

In operation, the stencils 5 are fed in a stepby-step movement along the guideway so as to position one stencil at a time directly below the ink applying roller 8. During the operation of the machine, the roller 13 is continuously rotated and the carriage 9 is oscillated by mechanisms not herein shown.

The transfer roller 11 is inked and rotated by the supply roller 13. During the rotation of the roller 11, the shaft 36 is rotated, thereby reciprocating the sleeve 35 and roller 30 through the action of the pin 11 and race 45. The reciprocating roller 30 distributes the ink uniformly over the surface of the transfer roller 11.

\Vhen the carriage 9 is in elevated position, as shown in F ig. 8, the ink applying roller 8 is inked and rotated by the transfer roller 11. On the downward stroke of the carriage 9, when the roller 8 approaches printing position, the shoulders 52 of the arms 50 engage the stop 7 for limiting the downward movement of the frame 10. As the carriage 9 continues its downward stroke, the ink applying roller moves out of engagement with the transfer roller 11 and is pressed downwardly upon the stencil. The roller 8 is resilient so that the portion thereof which engages the stencil is flattened by the pressure of the carriage 9 so as to apply ink to a considerable area on the stencil.

When it is desired to remove the transfer roller, the springs 29 are disengaged so as to permit the levers 26 to be moved out of engagement with the shaft 24. The entire framelO, roller 11 and distributing mechanism 12may then be removed as a unit from the carriage.
