Be it known thatl, FRANK H. QUADE, Jr., a citizen of the United States, residing at Fresno, in the county kof Fresno and State of California, havey invented certain new and useful Improvements in Inking Mechanism, of which the following isa specification.

rlhis invention relates k.to machines for printing letters, 'circulars and the. like, by which the heading of the letter may be printed with ordinary printing ink of any desired color, the body of the letter through an inked ribbon, and the signature from an electrotype or the like so inked as to give the effect of having been Written. A type of such machiney is disclosedy in Letters- Patent, No. 1,041,314, granted to J. F. Mahlstedt, October 15th, y1912, and the present invention relates especially to the inking mechanism or the means employed to trans fer ink from a source of supply to the electrotype and to the type facesfroinwhich the letter head is to be printed.`

rFhis application is a` division of an application filed by me August 2nd, 1913, Serial No. 782,729. 1

The improvementsconstituting the present invention Will be hereinafter first fully" described and thenmore particularly pointed out in the claimsfolloiving the description. ln the accompanying drawings, which fully illustrate my present invention:-y

Figure 1 is a longitudinal vertical section of so much of a printing machine as is necessary to imparta proper understanding of the general arrangement and the particular features forming the subject-matterof my improvements; F ig. 2 is anfenlarged perspective View of the ink trough ivithits supe ports and the parts immediately kco-acting therewith; Fig. 3 is a longitudinalsection 'through the ink trough shoivingthe .parts in operative position; Fig. .-{Lis a similar view showing the parts adjusted to prevent` the feeding of ink; Fig. 5 is a detail` vieiv of ay latch employed in connection With they ductor roll; Fig. 6 is a deta'ilvieiv of a` ack 1 bar which is provided on one side of thetype bed; Fig. 7 is a detail perspective view of ay portion of the ink-trough support; Fig. 8

is a perspective view of theV mechanism for` rotating the ink table; Fig. 9 is a detail bot-y tom plan vieiv of ,a portion of the mechanism shown in Fig. 8.

a link 4. Motion is imparted to the lever3 through a crank shaft .5 and a pitman .6 which may be actuated through 'any convenient mechanism. Upon the upper portion of the main frame is mounted an impression roller 7 working in connectionV With sheet feeding devices, indicated generally at 8, and

With a delivery mechanism, indicated generally at 9, by Which the printed sheets are removed from the machine. A throw-off leverlO is also mounted upon` the upper portion of the frame, and this levercontrols the` devices for feeding the ribbon and means for kstopping the operation of the machine when desired.

The type bed 2 as it reciprocates longitudinally of the main frame carries the type under the transfer rollers 11 by which the ink s transferred to the type faces, and my present improvements.l relate more particu larly to the means Vwhereby ink is supplied to these transfer rollers.V Said transfer rollers are preferably provided -in pairs, as shown in Fig. 1, one pair' being mounted upon the main frame near each end of the saine, and each ypair of the rollers applies ink to the faces of aportion of the type carj i'ied by the type bed.

`To thetype bedand projecting beyond each end thereof l secure brackets 12, eachof which isadapted to support an ink table 13 and means for periodically imparting av rotary movement" to said table. The ink table at each end-of the type bed is a duplicate ofthe table at the other end of the type,y

bed, and a description of one With its operating ymechanism will suffice for both.

upon reference-to Fig.` l that the brackets 12 vary slightly in'form at their inner ends. rlhis variance in form is merely to accommo-l It ivillV be observed the Opera# For f` convenienc-eand clearness in the illustration, konly one inking ltabley and its operatingA mechanism is shown.

end of this stud bears directly against the lower end of the 'stem so as to aid in support-ing said stem, while apm, indicated in dotted lines in Fig. 8is disposed eccentrieally upon the upper end of said stud and enters correspondingly located socket in the lower end of the stem whereby the rotary movement imparted tothe stud will be imparted directly to the stem and the ink table thereby given the Vdesired movement. A setscrew 18 is mounted in the side of the post and enters an annular groove 19 in the stud whereby to swivel said stud within the post, as will be readily understood. The stud will thus be prevented from dropping from the lpost and, at the same time,.willbe free; to rotate therein.

rFlic ink to be fed to the type is placed in ink troughs 38, one of which is provided at each end of the machine, as shown in Fig. l, and each ink trough is so located asv to bey within the vertical plane of the ink table coacting therewith@ The rear inktrough is supported by a cross bar 39 which is securedV rigidly to end brackets 40 secure-d to the main frame of the machine at the corners of the same, as willbe readily understood. The front ink trough is carried by a similar cross bar 39 to which brackets 40 are secured,

but the brackets 40 are shorter than the"` brackets 40, as shown in'Fig. 7, and the bar 39 projects beyond the brackets and is pro` vided with openings, as also 'shown in Fig.

7 through which screws or bolts are assed 3 b to secure the bar to the standards which carry the delivery roller. Y

Y Journaled inv and extending between the upper cornersv of each pair of thebrackets 40 or 40 is a shaft 4l which has the fountain roll 42 preferably integral therewith Vat a point about midway its length.l Immediately adjacent the endsof the fountain roll,

' the diameter of the shaft 4l is reduced,1as

shown` at 43, to permit the side walls 44 of v theink trough to enga-ge the shaft and fit close tothe ends of the said roll soas to pre- 1 vent leakage of Vink around the ends .of the roll. The ends of the said side walls are notched, as indicated mostV clearly inYV Figs. D

shaft, andthe edges of the notches, which are at an angleY tothe bottom of the trough,

should fit fairly snug on thershaft so as t0 make a tightt at point of Contact but a slight movement of the trough will leave an opening' between the trough and the roll.

o and4, so as to more readily` engagethe The action is thus positive when more ink is needed.

rlhe ink trough is preferably constructed of a sheet metal plate having its ends turned up yin triangular form to provide the side walls 44 and having one. side edge turned down, as shown at 45, to present a depending fiange or lip to facilitate the adjustment of the trough. The lower edge of the trough, as shownV in Fig. 4, may bear against the fountain roll 42 and', when the parts are in this position, no ink will be fed from the trough. The trough'rests upon the central portion of the cross bar 39 in an oblique position, as shown, and to the said cross bar I lit the end of a screw 46'which extends outwardly and upwardly through the depencling iiange 45 of the trough. An adjusting nut 47 is mounted 'upon the said screw and bears against the outer side of the said fiange, while a spring 4S is carried by the cross bar 39 and hasone end bearing against the inner face of said fiange 45 so as to act thereon in opposition to the nut-47. It will be readily understood that, by turning the nut in one direction, the trough will be forced inwardly and downwardly against the tension of the said spring and, by turning the nut in the othery direction, the spring will be free to eX- pand and thusmove the trough upwardly and outwardly. In this manner, the flow of the ink may be readily controlled so as to be cut'ofl1 entirely or fed at any desired speed or in any desired quantity to the ink table.

Below the ink trough a shaft 49, angular in cross section, extends between theL brackets 40 and has its ends journaled in said brackets. 'At intermediate points of the said shaft, I secure the arms 50 which project Alaterally.from'the saidV shaft to points below the shaft 4l Vand are adapted to carry the ductor rolll. The length of the ductor roll 5l is preferably the saine as the length ofthe fountain roll 42, but less than the distance between the supporting arms-50 so as to facilitate the 'fitting of the said roll between/said arms. V'The arms are constructed Y with openings near their Vfree ends adapted to receive the elongated pintles or trunnions 52 extending from the ends of the Vductor roll, and it will be readily understood that, by inserting one" efsaid pintles through the opening intended tok receivethe saine and sliding saidpintle beyond the point at Vwhich `it is to-be supportedtlie'pintleat the other endy ofj the roll may be brought into alinement withV its bearing and the roll and bothl pintles then again moved longitudinally so astofengage the last-mentioned pintle in its bearing. i

Oneof the'pintlesis preferably provided Y with an annular groove, and a latch 53 is pivotally mounted upon'the arm 50 which receives said pintle, Ysaid latchA being provided with a notch 54'to engage said groove iso ment with the adjacent pintle 52. Thefree end of the latch is preferably bent laterally to provide a handle or thumb piece 59 for convenience in releasing the samewhen it is necessary to repair or clean the machine. The *fountain roll .4-2 is preferably"-`con structed of some hard material, while the ductor roll 51 is preferably made of compo 7 sition. f

A floating weight 60 is provided in the trough to bear` upon the yink and fforce the same toward the rolls. This floating weight may lconvenientlybe in theV formk of a cylinder extending between the side wallsof the trough, but as it should not roll downwardlyy and thereby feed the ink too rapidly to the rolls, I provide a rod 61 which is rigid with the weight'and extends upwardly therefrom so as to engage over the upper edge of the trough. This rod, by its engagement'with the upper edge ofthe trough, will prevent rotation of the weight and also serves as a handle to ypermit the removal of the weight from the trough or its insertion therein.

At one end of the fountain roll shaft 41,'

I secure a ratchet wheel 62 which is engaged by a pawl 63 carried by a trip lever 611.' The said trip lever 64 is fitted upon the adjacent end of the angular ,shaft 49, and a spring 65 extending between the lever and the pawl 63 serves to hold the said pawl in engagement with the ratchet wheel 62. Ak lock nut 66 is fitted upon the pivot 67 of the said pawl, and the said rkpivotalso carries a roller 68 which is adapted to ride upon a track 69 provided on one side of a rack bar 70 which is formed upon or secured to one side of the type bed. The track 69 has one endfbeveled, as shown at 71, so that it will readilyengage under the roller 68 and thereby cause anupward movement of the lever 64 andpawl 63.

lt willl be readily understood thatl a track 69is provided near each end of the type bed, and that the inclined face ofy the said track extends in opposite directions at the opposite ends of the type bed. This arrangement is indicated at 71 and 72 in Fig. 6 of the drawings.

`VVlien the lever 64 is given'y a vertical movement under the action of the track 69, as justjdescribed, the ratchet wheel 62 will be partially(l rotated and a partial rotation thereby given the fountain roll shaft 41 `,and the fountain roll 412. vAt the same time, the

angular shaft i9 will be partly rotated inasmuch as it must follow the movement of the lever 6d whichis fast thereon, and the arms 50 will be thereby swung upwardly so as to carry the ductor roll against the fountain roll to receive ink therefrom. The parts will remain in this raised position as long as the roller 68 isin engagement with the track 69, and the ductor roll will thereby receive a full supply of ink from theL fountain roll. lVhen the roller 68 reaches the inclined end of the track upon the reverse movement ofthe type bed, the parts will 'be returned tok their lower position and the ductor roll will bear upon .the surface of the yink table which will then take ink from the roll. On' the next'movement of the type bed, the transfer rolls 11 will receive ink V from the ink table and in turn will apply the ink to the type faces."

A spring, yindicated at 7 3, is coiled around the endV of the shaft 49' andhas its ends se#r cured respectively to the lever Gaand the, adjacent bracket Ll() so that, as the inclined end 71 or 72 of the track 69fpasses from under so' l the roller 68, the partswill be positively moved to their lower position so thatthe ductor roll will be in position to hear upon the ink table. At the opposite end ofthe said shaft 49 I secure a stop arm Tlwhich projects outwardly and upwardly from the said shaft and is equipped at its upper end with a stop 75 adapted to bear upon the cross bar 39.y This stop is preferably'in the form of a segmental disk pivoted to the upper end of the arm 7 l and held in frictional engagement therewith by a spring 7 6 coiled around its pivot between the saidy arm and the head of the pivot. The parts are so proportioned and relatively arranged that, when the straight edge of the segmental disk is presented to the crossy bar, the shaft Y v 49 may oscillate and the ductor roll drop tothe ink table, but when the curved or arcuate edge of the disk is presented to the cross bar, the stop arm 7 l will be held away from the cross bar and the shaft 4:9 held in such positionthat the ductor roll will be maintained raised against the fountain roll. This mechanism, it will Vbe readily under! stood, permits the operator to easily control the feed of ink andy retard the flow when the supplyv upon the ink table should tend to becometoo copious or thick for successful printing.

s In Figs. 8 and 9, l have shown lthe mechanism for imparting rotary movement to the y ink table. The post-78 on the'frame 12 receives the stem 79 of the ink table, and the lower portion of the stud 80, and belowl the` said ratchet Wheel aswinging plate 82isv pivotally mounted upon the stud, a washer 83 V'being fitted upon the stud below the said plate 82 to retain the same in place. The operating lever 84 is disposed transversely to the frame Vl2 and is pivotedito one side of the same, as indicated at 85, a link 86, having its opposite endsr pivoted respectively to the said lever and the plate 82, serving to connect the lever andthe plate and transmit the mo-tion of the lever to the plate, aswill be readily understood. The pivot which connects the link to the lever is in the form of a post 87 to which is' secured one end of a' spring 88 having its opposite end secured to the frame l2 at a point Vnear the post 78. A pawl 89 is pivoted upon the swinging plate 82 and is held in Yengagement with the ratchet wheel 8l by a'spring 90 which is coiled around the pivot 91 of the pawl and has its opposite ends engaging the pawl and a pin 92 on the plate, as clearly shown in Fig. V8.v To prevent retrograde movement of the ratchet wheel, a VholdingV pawl or dog 93 is pivoted upon the frame 12 and is held toy the ratchet wheel by a spring 94 coiledaround the pivot 95 of the pawl and having its opposite ends respectively engaging the pawl and the holding pin 96 on` the frame. A post 97 is carried bythe main frame of the machine inthe path of movement of the lever 84;. The post is formed at its lower end with a U-shaped stirrup which is pivoted Within the U-shaped operation of they machine, the transverse le-y ver 84 will ride against the post 97 and cause the same to swing down into the housing or supporting bracket 98 within which 1t Y is pivoted. When the lever 84: has cleared the post 97, said post will return Yto its upright positionY under the influence of the spring 99, and on the return movement of the type bed the outer edge of the'lever 84 will engage the said post. As the post cannot swing outwardly, the lever willbe forced to swing inwardly and towardV one side thereby Vexerting a pull upon the plate 82 through the link 86 and against the tensionV ofthe spring 88 whereby the pawl 89 will be'caused to ridefover the ratchet wheel 81.1 As soon as the vlever 84clea'rs the uprightpost 97 ,V the spring 88 will contract rand thereby swing the lever 84V to lts normal position and the link 86 will then exert a push-` ing force upon the plate 82 sothat the pawl '89 engaging the ratchet wheel 8l will rotate said ratchet wheel and through the intermediate parts will effect a partial rotation of the ink table. IVith the mechanism just described, the ink table may be given a quarter turn at each successive operation.

From the. foregoing description, taken in connection with the accompanying drawings, it will be readily seen that I have provided exceedingly simple and compact mech anism bywhich the ink may be eectually transferred from the ink fountain to the type faces, and that the ink will bedistributed evenly over the ink table and, consequently, applied evenly to all the type faces. The iiow of the ink may be easily regulated and no waste of the Yink will be permitted. The mechanism'for rotating the ink table is all belowrthe table, andzthere are Vno notches in the edge of the table or openings through the table through which the ink might leak and be wasted. TheinkV tablemay be readily removed from its bearing without disturbing the operating mechanism and repairs may be easily made when desired. The'ink willI be taken from the ink trough or fountain onlyras it is needed', and Yshould the ink be supplied too fast, its flow may be retarded or cut olf until all the ink upon the ink table has been used. The stoppage or retardation yofthe yflow from the ink trough, moreover, will not necessiytate any stoppage or reduction in speed of the operation of the printing mechanism.
