y ,Application'led August 20, 1901. Serial No. '72,679.- (No model.)l
To all whom/kit may concern:
Be it known that I, GEORGE l?. FENNER,a citizen of theUnited States, residing at New Londoni n the county ofNew London and State of Connecticut, have invented new and useful Improvements in Printing-Presses, of which the following is a specification.
By means of this'inv'ention such operations as inking and feeding can be satisfactorily effected; and the invention'resides in certain novel features of construction set forth in the following specication and claims and illustrated in the annexed drawings, in which- Figure 1 is a side elevation of a press containing the invention. Fig. 2'is a plan View of Fig. l. with parts broken. ai az, Fig. 1. Fig. l.
In the drawings is shown a type-bed f and impression-cylinder g, the operation of which is known in the art. In Fig. 1 is indicated a rack 8, secured to the type-bedje, and the gear 9, alternately engaging the rack on opposite sides, causes this rack and bed to reciprocate. Traveling or reciprocating with this bed is a rack o., into which mesh the gears c, driving the ink-rollers la nearest the cylinder. Said gears c also engage the gear-Wheel b, or, rather, said gears being made in two sections c and c' the sections c engage such wheel b. This is so arranged as it has been found impossible or impractical to havethe gears or gear-sections solid or integral and at the same time mesh into both rack and gear, the rack cutting or forming a sort of chord along a side or face of the gear, so that the distance between the gears measured along the rack varies or is shorter than the distance between said points measured on an arc or on the circumference of the gear. Hence it is necessary to turn or' arrange the section c, which meshes into the gear bfa certain extent or fraction of a toothout of register with gear part c, vwhich meshes into the rack. After these two sections are turned a trifle in relation toeach other they are fastened together, or they could be cast in the desired relationship. On the hub of this wheel b or turning therewith is a smaller gear i, a similar gear being shown at the gear-wheel e, and these Fig. 4 is a section along Fig. 5 is a section along y y,
Fig. 3 is an end elevation of Fig. l,
gears 7S carry or engage rack h. As such rack h reciprocates the gears b and c rotate or oscillate in unison. The gears c are driven by the rackV a, the gears b by the gears c', while the gear t imparts motio'n to the rack 7?., which in turn drives the gear e and'thesecond gear c', which,y operates the fountain ink-rolls. The rackh is free to oscillate independently of the bed. The gear e engages the gears d, driving the inkfrolls, which are over the table orlocated some distance away from cyl inder g. These gears d are short or narrow that is, so arranged as to only mesh into gear e and allow rack h and vibrator-rack a to pass the face or sides of the gears without touching the same. a
In speakingof the gears c as driving the ink-rollers it may be noted that such gears really mesh into the gears which drive or are mounted on the ink-distributing rollers,which latter contact with the ink-rollers proper, and such ink-distributing rollers, in addition to rotary motion, are also normally given a transverse or axial motion.
The gears vl are shown smaller than gears l) e, so that the rack 7L runs at a dierent speed or more slowly than the bed.
Attached to the bed is shown what may betermed a register-rack, m, havinga joint or pivot connection n with the bed and held by spring o up against stop p. A gear-segment is shown at q on cylinder g. When the cylinder comes to the bed or these two parts come together, the yield or elasticity of spring o will allowthe rack to give or move so that the parts come together without so severe a shock as would otherwise occur if the parts were rigid or no provision made for yielding, especially when running at high speed. The spring is made stiff enough to bring the cylinder and bed together in perfect register but flexible enough to reduce the severity of the blow. y
In the drawings is also shown an arrangement by which the tongues Z are moved Without moving the feed-board r. The feedguides s are also movable. These parts are shown moved up and down by cams t, and the feed-guides are constructed in such manner that the register of the sheet is not affected by the operation. This construction is adapted for a two-revolution press, so that the tongues Zwill be up when the cylinder IOS comes around the second time to deliver the sheet. The raising of the tongues also raises the loose end of the feed-guide, and the sheet is allowed to pass out or to the delivery without being touched or disturbed by the feedguide apparatus. On the second time around when the grippers take a sheet the tongues are close down or to the surface of the cylinder, so that the sheet can be taken perfectly smooth by the grippers without wrinkling. The tongues Z can be suitably supported or jointed at u to the board, and a screw or stop arrangement o can be provided or adjusted to limit the drop or swing of the tongues. This tongue Z is shown in Fig. l as part of a complete machine, but no claim thereto is herein made.
In the drawings is shown a ductor-roller l, Fig. l, for taking ink from the fountain 2 or its roller 3 and applying the same to the inkdistributing roller 4,which in turn applies the same to the inking-rollers k away from cylinder g. These rolls 7e apply the ink to the table or ink-slab, which forms, as it were, the rearward extension of the type-bed f, and as this bed runs toward cylinder g, so that the ink-slab portion contacts with ink-rollers 7c near cylinder g, these latter rollers are inked, so as in turn to apply the ink to the type portion of the bed or table f. This ductor-roller 1 is applied above the ink table or bed fand is kept permanently out of contact therewith and is timed to swing to or contact with the Vibrating or ink-distributing roller 4, while the latter is practically at rest or has temporarily stopped rotating or moving. By this arrangement the backlash or rattle at the gears of the ink-distributing roller, caused by a ductor-roller contacting with an ink-distributing roller while in motion, is avoided, thus preventing not onlynoise,which is objectionable, but also preventing the rollers or their bearings from working loose. This ductorroller can be mounted in a suitable way for vibrating or contacting with the ink -font roller and the ink distributing roller. A swinging arm or lever 5 is shown supporting the ductor-roller, which arm 5 is linked to or actuated by lever 6 and cam 7. This ductorroller being brought into contact with the inkdistributing roller 4 when practically at rest or at the beginning of a series of revolutions in one direction of said roller 4, the ink will be thoroughly or uniformly distributed about the entire circumference of the ductor-roller and of the rollers 4 and 7a and also of the inkbed, so that when the latter moves to contact with rollers 7.: the ink.v is uniformly distributed to insure satisfactory inking of all the type. The ductor roller l or its shaft or mounting being applied above the ink table or bed f allows ready mounting and dismounting of and access to the ductor-roller and leaves a clearance or space between the inkfountain, the inking-rollers, and the ink table or slab.
In stating that the ductor-roller is made to contact with the ink-distributing roller when practically at rest it is understood that the vibrator-roll need not be absolutely still, but practically at the point to where it comes to rest. As the vibrating roll reverses almost instantly, it might be a little difficult to bring these two rolls together exactly at this point of absolute rest.
As to the purpose and advantage of this construction and of the function secured by this invention it may be stated that the gearing for driving the table ink-rollers is simple, noiseless in its action, that there are few working joints between bed and table ink-rollers, and that there is no liability to get out of order. The ink-carrying roll, which swings between the fountain and the first vibrating roll, is brought into contact with roller 4 when at rest. This prevents noise which would be caused by starting the carrying-roll quickly at high speed.
What I claim as new, and desire to secure by Letters Patent, is-
