This-invention relates toprinting apparatuses and particularly to printing mechanisms adapted for use in connection with addressing machines and similar devices. I

The main objects of this invention are to provide a printing apparatus having improved means for supporting the ink applying member abovethe guideway along which the stencils or other forms are fed step-bystep; to provide improved operating mechanism for reciprocating said supporting wherein means so as to move said ink applying member into and out of efiective engagement with the stencils; to provide an operating mechanism of this kind'having improved means for continuously reciprocating said supporting means between predetermined limits so as to move the ink applying member into close proximity with every one of the stenoils and having other meansselectively controlled .for moving-said supporting means beyond one of said limits for pressing the ink applying member into eflective contact with the selectedstencils; and to provide an apparatus of this kind which is simple in construction and quiet in operation.

An illustrativeembodiment of this invention is shown in the accompanying drawings,

' Figure 11 is a top plan of an improved printing apparatus, showing also a portion of an addressing machine 1 Fig. 2 is a vertical transverse section taken on the line 22 of'Fig; 1 and showing the ink applyingmember in its uppermost posit1on.'-@

.Figc 3'is a view similar to Fig. 2, but show- I ingthe ink applying member in close proximity to thestencil guideway.

but showing the ink applying member pressed into effective contact with a stencil.

bodying this invention is'adapt'ed for use in many different types of machines but, in the specific form herein illustrated, the-invention Fig.4 is a view similar to Figs. 2 and 3,

is applied to an addressing machine. Inasmuch as this invention relates particularly to the printing mechanism, certain parts of the machine not relating thereto and believed unnecessary to a complete understanding of the invention have been omitted from the drawings.

In the construction herein shown, the improved printing apparatus includes an ink applying member supported on a carriage,

which is oscillated continuously between predetermined positions for moving the ink applying member continuously toward and from the stencils or other forms. The actustroke of the carriage to press the ink applying memberinto eflective contact with the st'encils'which are selected by the selector mechanism.

, In the embodiment illustrated, the printing mechanism is applied to an addressing machine having a horizontal table or bed 1, on whichiis mounted a pair of spaced rails 2 forminga gu'ideway for supporting and guiding a plurality of stencils 3, which are fed step-by-step through the machine so as to be operated upon by the improved printing mechanism and by various other mechanisms, not shown.

, Located between the bed 1 and guideway 2,

- is a passage 4c for receiving a stack of envelopes 5 upon which the addresses are printed from the stencils. Located directly below the stencil guideway, in vertical alinement with the impression member, is a vertically movable platen or anvil 6.Which is adapted to raise the stack of envelopes into position to permit the top one to receive the impression.

The platen 6 and its operating mechanism are more fully shown and described in the copending application Serial No. 347,004, filed March 14:, 1929.

In the form shown, the printing mechanism includes an ink applying member 7 mounted on a carriage 8 pivotally supported on a frame 9 and adapted to be oscillated by improved operating mechanism 10.

The ink applying member 7 comprises a roller journaled in the carriage 8 and adapted to receive ink from suitable distributing rollers, not shown.

a The carriage 8 is in the form of a yoke having a pair of end 1 members 11 connected" to an integral cross brace 12. Formed on the end members 11, are bosses 13 which are journaled on bushings-.14on a shaft 15-, which is supported in the frame 9 and which forms the pivot on which the carriage 8 oscillates.

The frame 9 is rigidly mounted on the bed 1 and comprises a pair of side brackets 16"and l7 and a connecting base part 18 located substantially in the plane of the guideway 2.,

The improved operating mechanism 10 includes means 19 adapted to COIltlIlllOllSlY osby any suitable means, not shown.

The eccentric 22 is journaled on a bushing 1 24, which embraces a fixed shaft 25'supported 28-and 30 are fixed on 'thesleeve 26 and shaft 21, respectively, and the gear 29 is journaled on a stud 31 fixed on the bracket 16;

The toggle 23 comprises a link'32 andan arm v33 pivotallysecured together by a pin 34. Supported in the outer end ofthe link ria'ge 8. The screw 3? permits adjustment of'the stroke of the carriage 8 forvarying I or strap 38 which loosely embraces the eccentric 22 for imparting a forward and back- 32, is a pivot pin 35 having a block 36 which has threaded engagement with one end of a screw 37supported in the brace 12 of the carthe pressure of the ink applyingroller 7 upon the stencil.

Integrally formed on the arm '33, isja sleeve ward movement' to the toggle 23 during the rotation of the eccentric so as to oscillate the carriage 8 'androller 7 between the positions "illustrated in Figs. 2 and3".

Theselectively controlled means 20," which presses the roller 7 into contactiwith the selected stencils], includes a strap 39 loosely em- 7 bracing an eccentric 4O fixed on a driven shaft the arm 33 of the operatin'g means 19', sothat,

" upon rotation of'the eccentric 40,"the pivot tionc one stencil pin 34 is lifted so as to extend the toggle 23 at the same time that the toggle is moved forwardly under the action of the eccentric 22.

The eccentric 40 is keyed to the shaft 41 and'is securedagainst outward'movement by a split washer 44'seated in an'annulargroove 45 .ofthe shaft 41.

The end of the shaft 41, which supports the eccentric 40, is journaled in the bracket 16.. The other end ofthe shaft 41hasa reduced part 46, which is journaled in a bore 47 of a stud 48' rotatably; supported in an upright post 49. I

S'ecured to the shaft 41,is a collar 50,which engages the bearing 16 for securing the shaft against withdrawal from the stud 48." cillate the. carriage 8 between predetermined Fixed on the shaft 41, is a'gear 51 meshing with a gear 52, which is fixed on a sleeve 53 loosely supported on, the'drive'shaft 21.

.The sleeve 53 is partof a, selector mechanism 'which is controlled in'its operation by certain indicia on the stencils. The selector mechanism is shown and ,described in Patent No. 1,708,268, issued April9, 1929.

Fixed on the sleeve 5-3, is a" second gears 54'which meshes with gear 55 fixed on the stud 48; The stud 48 is geared to a shaft 56,'which actuates' the'anvil 6 by means of the intermediate mechanism shown and described'in said co-pending application.

' The;gears,51', 52, 54'and 55 are mutilated,

as ,illustratedin Figs. 1,5 and 7 so that, during the impression operation, the anvil 6 'remainscat Irest andQduring the downward movement of theanvi'h'the operating means 20 is unaffected by thefrotation of the sleeve 53. p V Inoperatiom'the stencils'3 are fed'stepby-stepalong the guideway 2, so as to posiatla time below the impres sionroller7. I r During the'operation" of the machine, the shaft-21 rotates continuously so" as to drive the roller 7 into close proximity with each ofthestencils through the action of the carriage 8',toggle 23,-and eccentric 22.

When a selected stenciljappro'aches printing position, the sleeve 53'is rotated, so as to rotate the shaft 41 an'd eccentric 40. Upon rotation of the eccentric 40, the strap 39 is lifted, thereby extending the toggle 23 'so as to force the ink applying roller 7' into effective contact with theselected-stencil, as

shown in Fig. 4; A v n Although but one "specific embodiment of i this invention has been herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted withoutdepartin g from the spirit of thisinvention as defined by the following claims.
