T all whom: il: 'n1/n.1! concern: I

Be. ity known that I, LOUIS SCIILESINGER, a ei tizen ofthe United States, and a resident o f ltlilwaukee, county of Mi Waukee, and State of Wisconsin, have invented certain new and useful Improvements in Printing Apparatus, of which the following is declared to be a full, clear, and exact description.

'lhe invention relates to a printing apparatus and seeks to provide a sim le and effectinay .be rapidly quiring special s tor.

The invention consists in the features lofv construction, arrangements, and combinations of parts hereinafter set forth, illustrated in the accompanying drawings, and more printed by hand without re- {ill on the part of the opera- The improved apparatus comprises a bed, which is preferablystationary, and a carriage, which ispreferably arranged to slide upon said bed. Impression and inking rolls are carried b v the carrlage and so arranged that either one may be thrown into operati-ve rlation with the printing-surface on thebed.

In the drawings, Figure 1 is a sectional elevation of the improved printing apparatus. Fig. 2 is a plan view of the bed and connected parts, with the's des of the carriage shown in section. Fig. 3 is a cross-section through the bed and carriage, showing the inking-roll in operation. Fig.'4 is a similar'view looking in the opposite direction,showingthe im' res- Fig. 5 is .a detai section on line 5 5'of Fig. 4. Fig. 6 is a detail section on line 6 6 of4 Fig. 1.

The bed of the a paratus comprises Side bars l0, connected ffy cross-bars l1, 12, and 13, preferablycast in piece with the side bars, and is sustained upon suitable cushionedfrwt 14. The sliding carriage comprises the 17 and 18, whichare preferably cast in piece with the side pieces. Laterallyprojecting s.-.3 and 4),are secured to the lower ends o the sides v16 of the' carriage and are arranged to' engage V- shape grooves 20, formed in the outer faces and. near theupper end of the'side bars 10 of the bed. By this arrangement -the carriage -inking rolls are so mountediu on the swingis free to slide back and forth upon the bed, but rigidly held against vertical play upon l lation with the printing-surface 11p n"t,he bed. i

The im ression and inkiner rolls are. journaled (firectly'upon the sliifter or shifting sup ort, and the latter 'preferably eomprises L-s aped side ieces 25, pivotall)v connected by bolts 26 to t e sides 16of the carriage and between the cross-bars4 17 and 18 thereof. The side pieces of the shifting .support arc connected by a cross-piece. 27, prefer .ri bly cast in piece therewith, and are also connected at their upper ends above the pivots 26 by a handle 28.

.The impression-roll .23 may be' of any suitable construction, but is preferably provided with a rubber cover. 'Ih'is impression-roll is mounted upon a shaft 29,'journaled between the L-shapedside ieees 25 of the shifting support at one end o' the lower portion thereof. At the other end of the lower portions of the L-shaped side pieces is journaled the supporting-shaft 30 of theinking-roll 24, which is formed of any suitable composition. 'lhe inking-roll is preferably removably mounted, so that it may b e changed or renewed when necessary. For this purpose the ends of its -inking-rollr shaft 3() are set within open slots 31 in the lower projecting ends of the side p1eces25. Locking-hooks 32 arcpivoted to the side pieces 25 of the shift-Ing support and are -provlded with own-ended slots 33, arranged to engage the projecting ends of the shaft 30. The shaft 3() fits snugly within the slots 3l and 33, which are arranged at an angle to eachother, so that 'the inking-roll is removabl I but securely held in position.

t will be observed that the impression and ing support as to. be vertical y Inovable to and from the'bed or. printing-surface thereon and also that these rolls are so arranged relatively. tothe pivots 26 of the port, so that "as-the latter is shifted in one or the ,other direction either of said rolls may be sw inging sup- I IOO lation with the printing-surface on the bed.

o. Stop-lugs 34 areiixed to or formed in piece with the sides 16 of the carriage and engage' the sides 25 of the swinging support to limit .the inove'ment of the support andthe rolls Carried thereby in one direction. The lower ends of the swinging supports are arranged to f engage stop-surfaces 35 on the cross-barlof the carriage to limit the movement of the sup ort and rolls in the opposite direction.

he printing surface or form may bearranged upon the bed in any suitable mannen: blutpreferably the sides and cross-bars'll" and 12' form a receptacle intermediate the ends ofthe bed, in which is mounted a re'- movable chase. A ledge 36 is formed around the lower edges of the side and cross bars 10, v1l', 4and 12 within the chase-holding receptacle, upon which the chase rests.

The. chase comprises side and end bars 37 and 3:8-and a bottom late 39. The end bars 3 8 are provided with aterally-projecting pins 40.,.,arranged to engage slots 41 in cross barslll and.12, and one of the end bars is' v preferably provided with an overhanging lip 42 to. aid in lifting the chase from the bed of the lress. Impression-screws 43 are threaded t rough the chase at each corner thereof. The lower headedl ends of these screws rest uponthe ledge-36 at the bottom of the chaseholding receptacle, and their up er ends are slotted, so that they ma be rea ily adjusted by-.the screw-driver or ike implement. By

means ofthese screws the chase, togetherwith the type-forml thereon, can be accuratelyset in a plane parallel to the travel of.`

the. impression and inking Aroll and can be raised and lowered to compensate for variationsvin the thickness of cards or sheets to be printed. When the screws 43 have been set to.. so adjust the Achase with reference tothe ppthof, travel of the impression-roll as to give. accurate impression, the chase may be securely held in adjusted position by lock nuts 44, threaded upon the upper ends of the screws.

Hspring-actuated sheetdifter is provided v forfnormally holding the card or sheet tobe Pilltcd above the printing-surface or form in the chase, and suchI sheet-lifter is preferably ,mounted .directly upon the chase to be removable to. and from the press therewith. Asshownl, the sheet-lifter comprises side bars or'rails 45 and cross-bars 46 and 47. The side bars 45 are provided with inwardly-projecting ledges .48, upon which the side edges of. the card or sheet to be printed are sus'- tained.. In the preferred construction side bars45 are provided at each end with downwardly-projecting pins 49, arranged to slide through. openings formed in lugs 50, which project laterally from the sides 37 of the chase. The side bars are 'also guided in open- .bar.13 ofthe bed or frame of the press.

' thrown into and the other out of operative re- Y ended slots 45,1, formed in laterally-projecting v portions of the end bars 38 of the chase. As

most clearly shown in Fig. 3, washers 52 are mounted to slide upon the pins 49 and are arrangedto engage the laterally-projecting lugs 50 on the sides of the chase. vSprings 53 are coiled about the pins 49 and are interosed between the washers 52`and the side hars 45, so that the latter are yieldingly supported in position. It. will be observed that the sheet-lifting side bars 45 are readily removable from position, and when so removed the lower headed endsV of the pins 49 hold the washers 52 and springs 53 upon the pins. In this manner a single sheet-lifter may be employed with a number of different chases.

Preferably the cross-bars 46 and 47 j are adjustable, so. as to properly support sheets and cards of different sizes, and for this purpose the side b-ars 45 are provided with a series of openings 54, (see Fig. 1,) into which crossbars 46 and 47 may be adjustably inserted. To permit the ready adjustment of the crossbars when ,the side bars 45 are in position upon the chase, these crossbars are preferably formed of spring metal. As shown, cross-bar 46 is formed of spring-wire, while the cross-bar 47 is preferably flat and formed of resilient sheet metal.` An upwardly and side bars or' Trails 45 to depress the sheetlifter, so that the card or sheet to be printed may be forced by the roll against the type. (Indicated by dotted lines in Fig. 4.) When the impression roll or cylinder has passed the side rails 45, the spring 43 will raise the sheet-lifter and move the card or sheet up from the surfaceof the type-form. The inking-roll is also arranged to depress thesheet- IOC lifter, so that the cross-bars 46 and 47 may not be smeared lwith ink. For this purpose the shaft 30 of the ink-roll 24'is preferably provided with metal wheels 56, spaced apart from the body of the roll and arranged to engage the side rails 45 'of the sheet-lifter, as indicated in Fig. 3.

At one end of'the bed beyond the chasereceptacle is mounted a horizontal rotatable inking-table 57. As shown in Fig. 1, this inking-roll is mounted to rotate upon a spindle 58,. projectingupwardly from the cross- The hub .S9-upon theunder sideof the inking-roll is provided with ratchetteeth 60, (see Fig.

` (iol 6.) and a'swinging lever 61 is pivoted-be- (Tween its ends upon the bed at onel side of the ratchet. l he outer end of the lever 61 proieets through an opening 62 in' the side oli the lever- 61 and are-held agamst lateral twist hy means of pins 66, which engage longitudinal slots 67, formed 1n the ends of the lever. A lug 684 upon' the carriage 1sl arl ranged to engage the pawl-64 upon the outer end ol the lever 6l as the carriage is reciprorated. Lug 68 land pawl v64 are so beveled that as the r-:arriageis moved to the right -pawl 64 vwill be shifted inwardly-without movingtlm lever 61. As the carriage moves toward the left the lng 68 will engage paWl 64 and swing the lever 61 against the tension of its spring 63. The lug 65 and the ratchetdirection.

teeth 66 are, however,l so beveled'that during this movement pawl l1s shifted mwardly against the te'nsion of its spring 'and moves over the ratchet-teeth 60. lAs soon, how.-A

ever, as lthe lug 68 releases the 'pawl 64v the spring 63 will quickly return the lever 6,1, and the pawl 65will positively engage the ratchetteeth 6() and spin the inking-table through a considerable are. By `thus spinning the inking-table through indeterminatedistances the inlrwil-l heinore evenly distributed thereon than if an ordinary ratchet mechanism were employed for feeding the table intermittentlythrrmgh short regular ares.

In operation the handle 28 oflthe shifting support on the carriage is conveniently employed to'slide the carriage upon the bed and f also to hold the inking-roll in position to rel eeive ink from the table and ink the type during the movement of the carriage in one direction and to hold the cylinder or roll 23 in position to make the in'ipression during the movementol the carriage in the opposite 'lhe transverse handle'28 is so arranged that with one hand they operator may conveniently grasp the handle and cross-har 17 of the carriage to securely hold the impression-roll 23 in lowermostposition, (see l'ull lines in Fig. 1,) or the operator may with one hand' grasp the handle and cross-bar 'lhe stops 34 and 35 for lim-- iting the shil't of the swinging support and l'or limiting the movement'of the impression and inkingrolls to and from the bed and printing-surface thereon are so arranged that the inlring-roll 24 is moved slightlyAnearer the hed when in .lowermost position than is the ii'n'pression-roll,23 when the latter is in lmvermost position. By this arrangement 1 8 ol the carriage to hold the inking-roll in lowermost position, as indicated in dotted lines 1n Fig. l.

theroll'24 may 'properly receive inf from the table 57; hut the 1mpression-roll 23 cannot be smeared by thel ink-on thetable. 'lhe stopsf34 are,'however, so arranged as to prevent .excessive depression olv the inking-roll 24. The lowermost positions ol' the. impression and ink'ing rolls are shown' in full and dotted lines in F ig. 1.

The stops 35, prel`er.tbly so located that when the impression-roll 23 is in lowermost position it will be in or almost in vertical alinement below the pivots 26 of the shifting support, so that such roll will be held iirmly in position to make a properimpressionLand the operi-.tor is-not required to 'exert an undue amount of pressure upon the handle in order to hold the impression-cylinder properly in its work. `Moreover, by

holding the shifter against the stops 35 during the impression movement of' the carriage theimpression-rolls will. be brought to bear l' With the even uniform pressure necessary to make the proper imprint.y lt' is thus only necessary that the operator should hold the shifter against the stops 35 during the impression-strokes in order to accomplish uniform printing. The shifting support where- -on the impression and inking rolls are journaled is so balanced that, as indicated in Fig. 1, the'inking-roll 24 is normallyin uppermost' position, so that the hiking-roll is always removed from the hiking-plate when the press is not in operation. 'lhisv is a valuable feature, since if the inking-roll is lett resting upon the ink-plate it will become flattened and unit for use;

It is'obvious that numerous 'changes may be made in the ldetails of structure without departure from the essentials of the invention and that parts ot the improved device may be used without its adoption in entirety.
