In. a pending); .U.'S. application Serial No." 17,070, filed March 20, 1925, I have shown and described a machine embodying in its construction the essential and distinguishing features of the machine shown m'the present'case; this application being in large part a division of the aforesaid pending application and showing as the preferred construction a later development of the invention, improving and simplifying correspond ing features or elements of the machine shown in the pending application,

In said drawings, in which the same reference letters are used to denote corresponding parts in ditferent views the letter A denotes the main supporting frame having mounted thereon a reciprocating plunger B, which is provided with a suitable handle and carries suitable printing devices or a printing wheel frame C, which movable vertically therewith and carries type or printingwheelsof ordinary construction with the usual means for operating the same; all of said parts being. of well known construction so that they need not be specifically described herein. r

On tlaeinner sides of the upri ht members or legs of the. frame A are formed vertical grooves a which as shown in Figsu l and 5,

are located at one side of the lon -itudinal oscillatory movement will be imparted to the oscillating frame, throwing the latterframo into itsuppermost position when the plunger descends =and lowe'rmg it to the position shown in Fig. 4, on the upward movement of the plunger.

The oscillating frame E carries a fluid inking reservoirF and an inking or ink-deli ering roller I adapted "to contact with the printing means carried by the plunger on its upward movement for applying ink thereto; said reservoir being adapted to distribute ink upon the inkingroller which'in turn applies t'he'ink to the' type or printing devices.

The fluid inking reservoirhas its bearings (as shown more -clearly in Fig. 6) in the side plates of the oscillating frame to which are pivoted, on the inner sides thereof, between the endsof the inking reservoir and salt side plates, swinging levers or rocker-plates G in which the shaft of the inking-rollerl has its bearings. The larger ends of the rocker-plates fit 'loosely on i or around the trunnions or ends of the inking reservoir while opposite ends of the shaft of the ink ing roller Iprotrude through oblong slots 2' in said ide plates, so that the rocker-plates may be caused to rock or swing slightly on their pivots to throw the inking roller into or out of position to contact with the printing devices on the oscillatory movement of the oscillating frame. The fluid inking reservoir has secured thereon a body of absorbent'materialF? withwhiclr the inking roller contacts, and the inking roller,-which is preferably made of rubber,is held normally in position. to contact with the printing devices by spring-actuated means hereinafter *described.

Each rocker-plate has formed therein at the end thereof adjacent the inking roller an opening in whichis'revolubly fitted a cam shaft K which is revolubly mounted in the sideplates o'fthe oscillatingframe and-carries a cam or cams 7c fitting in said openings, so that by rotating the shaft said cams will engage the rocker-plates and move the latter to'throw the inking roller out ofposition to contact with the printing devices, or vice versa, according to the direction of rotation. A spring or springs H connected atone end with pins projecting inwardly from the ends of the rocker-plates opposite the inking roller and at the other end thereof with a transverse rod or bar It passing through oblong slots in said rocker-plates and secured at oppositc ends to said side plates, may be employed to hold the inking roller normally in ated means hereinbefore described.

The cam shaft K has its ends fitted in alined openings in the side plates of the oscillating frame and has fixed thereon or secured thereto at one end a resilient bow-shaped locking device L, one end of which bears against the a-djacentside plate of the oscilating frame while the other end, of tooth-like form, engages one of a plurality of depressions or recesses in .the adjacent side-plate and holds therocker-plates relatively stationary wit-h the inking roller normally in position to contact with the printing devices when the oscillating frame is moved by the phinger. By turning the cam shaft, the toothed end of the locking device will be caused to engage another depression in the adjacent side-plate and hold the rocker plates with the inking roller out of contacting'position, thus enabling the operator to throw the inking roller into position to conact with the face of the type or printing wheels or'to prevent contact therewith when the oscillating frame is lowered, he cam shaft is preferablyprovided with a milled wheel K on one end thereof by which it may be rotated when desired to shift the position of the inking roller.

'As will be seen, when the plunger depressed it will move the oscillating frame upon its shifting fulcrum, the studs 0 being guided along the vertical grooves a in the supporting frame and willthrow the lower ends of the swinging links D outwardly, and as thismovement is continued, the oscillating frame will be raised and with it the fluid inking reservoir and the inking roller, and thrown into the position shown in Fig. 5 out of contact with the face of-the type or printing wheels, and on the reverse movement the inking-roller will contact with and apply ink to the face of the type.

he fluid inking reservoir F preferably consists of telescopically connected inner and outer

tubular members

7 and 7 each open at one end and closed at the other end thereof, and one or both provided with a filling aperture at its closed end; said filling aperture being closed by a removable stopper 7; but instead of concentric tubes the connected membersof the inking reservoir may be of polygonal form in cross-section. Each member has minute orifices or pin holes therein which are arranged normally in separated relation but may be brought into registering position by adjusting or moving one member longitudinally upon or within Cir the other in the. direction of its axis. Preferably, each member is form'edor provided at the closed end thereof with a radially projecting flange or other suitable means for confining therebetween a cylindrical body F of absorbent material surrounding the outer 'member and adapted to revolve therewith.

Said absorbent body may consist of a cylinder of felt or other absorbent material of suflicient thickness and width to span the space between the end flanges of the two members of the reservoir, but preferably it consists of a series of rings or sections of absorbent material surrounding the outer member of the reservoir and secured together, as shown in Fig. 15, so'as inieffect to provide a solid body of cylindrical form within which theyouter member of the reservoir is inserted.

The inner member of the inking reservoir is provided at its closed end with an exterlorly threaded axial extension P which protrudes through an opening in the adja cent side plate of the oscillating frame E r and has screwed thereon a nut f having a groove in its periphery to provide radially pro ecting flanges f and f between which 1s pivot-ed intermediate its length a substantially semi-circular locking device F (IF 6 and 7) which carries at one end a stud or pin 7 adapted to enter a hole in the nut f and engage a registering hole or socket in the axial extension f so as to cause the nut and extension to rotate together while permitting independent rotary movement of the nut when said stud or pin is withdrawn from the socket or hole in said axial extension; such withdrawal being effected by pressure on the other end of said locking device which carries a spring f adapted to hold the stud or pin on the opposite end thereof normally in engagement with the hole or socket in said axial. extensionand to yield under pressure to permit the pin to be withdrawn. The peripheral flange f on the inner end of the nut f is recessed to proing the pin. and turningthe nut until. the pin snaps into another registering hole shown in the axial extension of the attached member of the inking reservoir.

To impart rotary movement to the inking reservoir, a pawl or dog M having a tooth m at one end is pivotally supported on one of the swinging links '1) and adapted to en gage a tooth of a ratchet wheel N when the oscillating frame is raised and impart a slight rotary movement to the ratchet wheet and through it to the inking reservoir and the inking roller when the oscillating frame is lowered; said ratchet wheel being secured to a gear wheel 0 on one end of the shaft ofthe fluid inking reservoir in mesh with a smaller gear wheel 0 on the adjacent end of the shaft of the ink distributing or ink ing roller, so that when the inking reservoir is rotated, rotary motion will also be imparted to the inking roller; the inking reservoir and the inking roller being thus caused to rotate in opposite directions.

In order to render the machine noiseless in operation and" to prevent jarring or injurious contact of the top of the printing wheel frame when raised by the plunger with the underside of the crossbar, at the top ofthe supporting frame, said crossbar has formed therein on the underside thereof sockets or recesses in which may be secured rubber pads l 'adapted'to serve as buffers and eliminate noise and rattle.

The supporting frame is preferably provided with a baseplate A of rectangular form, and'of greater width than the legs of the frame and provided withja rectangular opening therein to permit the face of the type or printing wheels to contact squarely with the surface of the material on which an impression is to be made; said base-plate having upturned .end-portions al which are secured to the legs of the frame resting thereon by bolts or other fastening means, and the working parts of the device are suitably covered to protect them from dust and dirt, by means such as are usually employed in machines of this type. I

In operation, the reciprocating plunger, which is heldnormally in raisedposition by spring-actuated means of ordinary construction, and automatically raised when free to rise, is forced downwardly by the band of the operator, causing the oscillating frame to swing upwardly along. curved lines eccentricto the center ofthe ratchet wheel, and the pawl M, being held in position to engage a tooth of the ratchel wheel N, will cause the latter to'rotate when the oscillating frame is lowered and impart a slight rotary movement to the inking roller, and the inking roller will be slightly rotated by the gears O and O to bring a fresh portion thereof into contact with the surface of the absorbent body covered by the inking rt-sen voir. On the reverse movement the pawl will slide freely over the inclined teeth of the ratchet wheel for engagement with another tooth'on the next return movement of the oscillating frame.

The modification shown in Figs. 9, l0 and 1.1., is substantially identical with the eenstruction shown in my pending application, above mentioned; the side plates of the oscillating frame, which carries the fluid inking reservoir, being eccentrically fulcrumed upon the legs of the supporting frame by means of pins or screws 9" inserted in interiorly threaded openings therefor in said legs and protruding into or through oblong slots Rin said side plates; said slots being inclined at an acute angle to longitudinally centrally disposed vertical grooves on the inner sides of the legs of the supporting frame, so that when the plunger lowered the oscillating frame ill be caused to swing upwardl upon its shifting fulcrum, causing relative movement of the pivot pins 0 along the vertical grooves and moving the oscillating frame into the position shown in Fig. 1.0 of the drawings, with the inking roller out of contact with the face of the type or printing wheels; the o )eration being substantially as hereinbefore described with reference to the operation of the machine shown in Figs. 1

to 5, and rotation of the inking reservoirand inking roller being effected by similar pawl and ratchet mechanism, as shown in Fig. 10.

But in this modified. construction, a roller I is interposed between the inking reservoir roller h and the inking roller I for spreauing the ink evenly on the periphery of the reser- Voir roller and delivering the ink to the inl? ing roller; said spreading roller being or ranged in peripheral contact with the inking roller and with the distributing or feeding surface of the fluid inking reservoir. This spreading roller 1 is preferably composed of felt or other soft and absorbent material, "while the inking roller is preferably composed of rubber.

In this modification, the spreading and inking rollers are carried by oscillatory levers or rocker-plates Glwhich are pivotally secured to the side plates of the oscillating frame on the inner sides thereof and carry at one end studs or pins 9 (see Fig. 11) which are connected by spiral springs H} with a transverse rod or bar 7: connecting said side plates so that the spring or springs will hold the inking roller normally in position to contact with the type or printing wheels on the oscillatory movement of the oscillating frame. The rocker-plates or levers G are forked at one end, as shown, to receive cams or eccentrics on. a cam shaft K whereby the position of the rockerplates or levers may be changed to throw the inking roller intoposition to prevent contact thereof with the surface of the absorbent body carried by the fluid inking reservoir, and vice versa, as desired.

The cam shaft K is revolubly fitted in alined openings in the side plates of the 0scillating frame and provided. at one project ing end with any operati lever or handle if having its free end turned inwardly to form a tooth adapted to engage depressions e and e in the outer side of the adjacent side plate of the oscillating frame E, so as to secure and hold the inking roller in either contacting or non-contacting position with the type, as desired. It will be yieldingly maintained in contacting position by the spring or springs acting on the rocker-plates to force the roller into contact with the type, until the cam-carrying shaft is rotated in opo'ositionto the force of the spring so as to throw the inking roller into position to prevent such contact. As shown, the cam-carrying shaft is in position to permit the spring to hold the inking roller normally in contacting position.

The telescopically connected members of the fluid inking reservoir may be adjusted to bring the orifices therein in registering position, or vice versa, and hold them in the desired position, by means such as here inbefore described for that purpose with reference to Fig. 6 of the drawings, or a springpressed lever T pivoted to one ofthe side plates of the scillating frame and hava forked end engaging an 'annulargroove f in an axial extension of one member of the inking reservoir may be employed for this purpose, as shown in Fig. 9; a spring (not shown) being arranged between the side plate and the free end of the lever, so as to normally hold the lever in position'to yieldingly hold the adjustable member of the inking reservoir with its orifices out of registering position with the orifices in the other member.

In the further modification shown in Fig. 12, the inking roller is dispensed with and the inking reservoir has its bearings in rocker-plates G fulcrumed at on the inner sides of the side plates of the oscillating frame E and serves the double purpose of supplying inkand applying it to the face of the type or printing wheels; said inking reservoir being held normally in position to contact with the face of the type orprinting wheels by means of a spring or springs H connecting studs or pins on the inner sides of the rocker-plates with a transverse rod or bar carried by and connecting the side plates of the oscillating frame; said rod passing through oblong slots in the rockerplates to permit a limited rocking movement of the latter. The rocker-plates G are provided with openings therein through which the axes or axial extensions of the fluid inking reservoir project and pass through sli 'htly enlar ed registering openings in the side plates so as to permit a slight roclszing or oscillatory movement of the rocker-plates when desired to throw the inking reservoir out of position to contact with the type or printing devices on the oscillatory movement of the oscillating Said-rocker-plates also have aimed openings therein to receive cams or eccentrics fixed on a cam shaft K by which the com bined ink reservoir and inking roller may be adjusted and held normally in position to either contact with the face of the type or printing wheels on the oscillatory movemei'i't of the oscillating frame, or out of contacting position, in a manner substantially as here inbefore described.

' In this further modification, in order to prevent the ink felt or absorbent body on the inking roller from gathering dirt or dust, I provide a cover for the inking roller comprising parti-cylindrical members U and U (Fig. 15) one of which encircles the roller, except at a point co-incident with the point of contact with the type, while the other is adapted to overlie said point, so that the roller will be completely housed within the two members; the. smaller member being slidable upon the larger member in the direction of rotation to expose the roller at said point; said slidablemember being provided with a handle o and having its ends fitted in grooves formed in circular plates V having central openings therein fitting over the axial extensions of the fluid inking reser voir or roller, as shown in Fig. 15, and forming with said parti-cylindrical members a drum-like structure in which the inking roller is enclosed.

In order to lock the plunger in lowered position with the oscillating frame raised, and to prevent accidental disconnection by jarring when not in. ,use, i I may pro-' vide a safety lock comprising an eccentric or cam W (see Fig. 18) secured on the underside of the top cross-bar of the supporting frame and adapted by partial rotation thereof to engage a shoulder at the base of a notch in the plunger rod B underneath said crossbar, so as'to prevent the plunger from being raised until released by rotation of said eccentric disk; the latter being provided with a millededge and secured in position by a set screw to as shown in Figs. 13 and let. i

The inking reservoir, in the form shown in Fig.6 of the drawings, comprisesinner and outer tubular members with orifices therein as hereinbefore described, which are fitted within a similarly perforated "tube having end flanges between which the cylindrical bodyof absorbent material is confined. In the course of manufacture one end of a perforated tube is first spun so as The housing shown in Fig. 15 is designed especially to protect the inking reservoir from dust and dirt when the machine is not in use, and the several parts are assembled by first placing the fluid inking reservoir inside of .the larger member ofthe housing, which is then, secured to one of the circular end platesV through a central opening in which an axial extension of the inkin reservoirhas been previously inserted, and therepon the other circular end plate is fitted over the other axial extension of the reservoir andsecured to said larger member by soldering or otherwise, whereupon the smaller slidable member is fitted in the groovesprovided therefor insaid circular end plates, as hereinbefore described.

lVhen using aninkingreservoir having a cylindrical body of felt or other absorbent material in molded form surrounding the peripheral enlargement of about four or five thousandths deep, in order that the ink passing through the orifices in the tubular members of the reservoir may fiowfreely and quickly around the outer tube; such construction also serving to prevent the ink from working out under the ends of the spun metal cylinder and on and out along the aforesaid end flanges. i i i To admit light at thelower end of the supporting frame, the upturned end portions a of the baseplate A may be cut away in substantially U-shaped form, so as to provide openings therein co-incident with openings formed inthe lower ends of up right members or legs-of the frame, as shown in the detail view Fig. 3
