Specification of Letters Patent.
Patented Oct. 30, 1917.
Application filed. November 23, 1916. Serial No. 133,037.
To all whom 2'25 may concern:
Be it known that l, VVILLIAM C. HART, a citizen of the United States, residing at the city of St. Louis, State of Missouri have invented certain new and useful Improvements in Printing-Frees Ink-Fountains, of which the following is aspec1fication, reference being had to the accompanying drawings, forming a partthereof. I
This invention relates generally to diskplaten job printing-presses and, more particularly, to certain new and useful improvements in ink-fountains especially adapted for use in connection with presses of the klnd stated.
One of the objects of my present nvention is to provide a disk-platen printing-press with an ink-fountain with which the type inking or feeding rolls, of which there are usually a plurality, in their upward travel toward the main inking-disk are each adapted to engage or contact with the fountain roll in advance of reaching the inking-disk, whereby ink from the fountain is evenly and smoothly distributed by the inking-rolls upon and over the inking-disk, the several inking rolls in their upward travel each carrying a 'daub of ink from the fountain and, to a certain extent, spreading the same upon the disk and in their downward travel toward the type further spreading or CllStIlb uting over the disk the ink carried thereupon by the rolls in their upward travel.
Another object-of my present invention is to provide a printing-press of the kind mentioned with an ink-fountain which is adapted to be alternately, in and during the operation of the press, thrown 0r rockedinto and out of operative ink-supplying position relatively to the type-inking or feedingrolls, so that the inking-rolls will engage with the fountain roll only when and as the inkingrolls travel upwardly toward the inking-disk of the press,'the inking-rolls traveling in front of the fountain-roll, but without engaging or contacting therewith, when traveling downwardly to ink the type, whereby the type is uniformly inked throughout and daubs of ink upon the type avoided and heater and cleaner printing-jobs obtained. A further object of my present invent on is to provide aprinting-press of the kind stated with an ink-fountain which is adapted to be thrown or rocked into and out of operative inlrsupplying position relatively to the type-inking or feeding rolls simultaneously with and as the throw-elf lever of vention is to provide an ink-fountain for.
presses of the kind referred to which is comparatively simple and inexpensive in form and construction, and which is adapted to be conveniently attached operatively upon the press.
With the above and other objects in view, my present invention resides in certain novel features of form, construction, arrangement, and combination of parts, all as will hereinafter be described and afterward pointed out in the claims.
In the accompanying drawings,-
Figure l is a fragmentary side elevational view of a disk-platen job-printing-press equipped with an ink-fountain embodying my invention;
Fig. 2 is a fragmentary rear elevational view of the same;
'Fig. 3 is a side elevational view of the fountain in non-ink-supplying position relatively to the type-inking or feeding rolls;
Fig. 4c is a slightly enlarged side elevationa-l view of the fountain in ink-supplying position relatively to the type-inking rolls;
Figs. 5 and 6 are, respectively, plan and front elevational views of the same;
Fig. 7 is also a side elevational view of the fountain and its associate parts, the fountain being again shown in nonink-supplying position relatively to the type-inking rolls;
Fig. 8 is a similar view with the fountain in ink-supplying position relatively to the typeinking rolls;
Fig. 9 is a perspective view of an adjust able cover-plate which I prefer to employ with my new fountain to reduce the ink-delivering surface of the fountainroll;
Fig. 10 is a plan view of the fountain equipped with the adjustable cover shown in Fig. 9;
Fig.,11 is a longitudinal sectional view through the fountain on approximately the line l111, Fig. 10; and
Fig. 12 is a front elevational view of the fountain shown in Fig. 10.
Referring to the said drawings, in which like reference characters refer to like parts throughout the sveral views, my ink-fountain isespecially adapted for use with diskplaten job printing-presses of present standard construction; and 1 have here shown only such parts of a press of the kind mentioned necessary for the purpose of illustrating the operative connection therewith of an ink-fountain embodying my invention. ()f the press shown, 1 indicates a portion of the frame. Pivoted upon the frame 1 is the type-bed portion 2 of the press. Journaled upon the press-portion 2, is the usual back cross-shaft 3, mount-ed upon each end of which is a roller-frame l, the rollenfranms d, which are connected by a rear cross-piece 5, supporting and carrying the type-inking or feeding rolls 6, three in number in the present machine. Suitably journaled upon the press is a disk or gear 7, pivot-ally attached eccentrically at one end to which is a rod 8 also iv'otally attached at its other end to an offset 9 on shaft 3. Pivotally fastened at one end to a fixed part of the press is an arm 10 having its other end pirotally attached to an upwardly projecting portion 11 of the roller fraine Suitably mounted for rotation upon the press portion 2 is the usual inain inking disk 12.
In the operation of the press, as will be understood, on the rotation of gear or disk 7, the roller fraines 1 will be rocked to carry the inking rolls 5 upwardly upon disk 12, then downwardly upon disk 12 and across the type-bed 1 3 ofthe pr ss, and then upwardly again, etc. 11 indicates f the press, the throw-off lever, which is suitably pivoted upon the frame 1. Pivotally fastened at one end to'the lower end of lever 1-1 and at its other end to an arm 1-3 pirotally mounted upon the frame 1 is a link 1G. 1? indicates a bell-crank lever also piroted upon the frame 1, one arm 18 of lever 1'? being longitudinally provided with a slot 18, working in which slot 18 is a roller 19 mounted on the arm 15. Piyot'ally attached at its lower end to the other arm 20 of lever 11, and at its other end to 9 of shaft 3, is a rod 21.
Nornially, as when lever let is in the position thereof shown in Fig; 1, the platen (not shown) of the press and the type-bed will, in the operation of the press, be alternately brought into and out of printing position relati ely to each other; on throw-off lever 11', however, being actuated to the left or in the direction of the arrow shown in Fig. 1, the back shaft 3 will, through the parts described, be rotarily nioyed to a certain extent suflicientiy to throw the type-bed portion 2 of the press out of printing position relatively to the platen, should the press be continued in operation, all as will be fully understood.
fhe ink fountain includes a box-like re'cep ta'cle open at its top and front side and coinprising a bottom wall a rear wall 23, and
side walls 2-l24e. Disposed obliquel'y with in the box and fastened at its rear end to an enlargement of rear wall 23, is a more or less spring-plate 26 yieldingly hearing at its forward end upon the upper face of hottorn wall V Jouriialed in the side walls of the box and extending across the box at its forward end is a shaft 27, fixed upon which, to rotate within the box, is a roller 28. Disposed longitudinally of the box and threaded through its rear wall 23, is one or more adjusting screws adapted to engage at their forward ends with plate 26 to adjust the position of the forward end of plate 26 relati ely to roller 28 to regiilate the flow of ink from the fountain. Bottom wall 22 provided with a depending log 30 which is adapted to adjustably seat in a longitudinal recess or slot 31 provided in an elongated strip or plate 31, the box being adjus' =bly secured to plate 31 as by means of a bolt 32. The strip or plate 31 is provided with a depending eye 53 adapted to be pii'otally fastened to suitable perforated ears as on a second plate or strip 35. This plate 35 is provided longitudinally at its rear end with a slot, as at 36, to adjustably receive a fastening bolt 37 for securing the fountain upon the press. Interposed between the plates 31 and 35 at their forward end, and
suitably held in position, as by means of a stud 35, is a coiled spring 36 adapted to yieldingly inaintaiir plate 31 and the fountain box mounted thereupon in properly spaced relation from lower plate 35-. The plate and the parts just described are adjustably fastened upon the typebed portion 2 of thepre'ss at a suitable point below disk 12 and in operative position relatively to inking rolls '6, so that the inking rollers 6', in their upward travel toward disk 12, will engage with fountain roll 28in adiance of reaching inking disk Further, each roller 6, in its upward travel, will in turn engage with fountain roll 28 and carry a da'ub of ink therefrom to and upon the disk 12, the rollers 6, in their continued upi v .rd travel spreading upon the disk 12 the 1111*. so carried thereupon, and afterward, in their downward travel, further spreading upon the disk the ink so carried thereupon by the rolls 6 in their upward travel, w iereby the ink upon the disk 12 is evenly and smoothly distributed thereupon and daubs of ink avoidedupon the rollers G and consequently also upon the type.
Fastened at one end, as by a clamp to roller frame *1, isa link 39, pii'otally counec'ted at its other end to one end of a second link it), link 10 having its other end loosely fastened to an extension 11 of shaft 27.
Fixed upon extension 410i shaft 27 is a ratchet wheel d2, engaging with which is a pawl 43 pi 'iioted upon the linl 10. As roller fra'ine is rocl'red or recipro'cated in the operation of the press, fountain roll 28 will,
through ratchet wheel 42 and its cooperating pawl 43, be step by step rotated to present a fresh ink supplying surface to the type inking ,or feeding rolls 6 as the same are moved upwardly to carry ink from the fountain to the disk 12.
Loosely sleeved on shaft 3 is a collar or the like it, provided with a camportion The collar ill is provided with a pair of laterally projecting spaced pinselti, with which is adapted to engage a notched spring 4:7 fastened to and upon the press, as seen particularly in Figs. 3, a, 7, and 8, to prevent lateral movement of the collar is upon the shaft 3.
Threaded into collar 44 at approximately right angles to each other is a pair of rockerarms 48 and 49, the arm 48 being provided with a lateral extension 50.
Fountain plate 31 is provided at its rear end with a bored portion 51, adjustably fastened in which, as by set-screw is a short staff or rod carrying av roller 54: at its lower end, the roller 54: being adapted to roll upon and engage with the collar and its cam-portion Reference being now had particularly to Figs. 7 and 8, it will be seen that when the roller 5st is out of engagement with cam-portion 15 of collar 44, the fountain boX and its roller 28 will be in ink supplying position relatively to inking rolls 6, so that said rolls 6', when moving up wardly, engage with the fountain roll to take ink therefrom to'disk 12. I
The inking rolls 6 having reached their uppermost position upon the disk 12 ant roller frames t being now, in the operation of the press, actuated to carry the rollers 6 down from disk 12 andacross thetypebed, the roller frames will, at their crosspiece 5, engage with the rocker arm 49 and throw the same into the position thereof illustrated in Fig. 7. In such movement .of rocker arm t9, collar fr-l: will be rotarily moved on shaft 3 to bring its cam-portion -15 beneath roller 5%, whereupon the fountain will be thrown, against the resiliency or tension of spring 86, into the position thereof illustrated in'Fig. 7 out of the path of rollers 6, so that said rollers 6 in traveling toward the type 2 will escape any contact or engagement with the fountain roller 98. Thus I avoid daubs of ink being carried upon the type from the fountain and obtain cleaner and ncater printing jobs.
On the roller frames being againactuated to carry rollers 6 upwardly, the roller frame 4 shown will engage with extension 50 of arm 48, throwing the same from the position thereof shown in Fig. 7 to the position thereof shown in Fig. 8. In such movement of arm 48, collar it will be reversely moved ,on shaft 3 to carry its cam-portion from beneath roller 54, whereupon the fountain, under the influence of spring 36,
will return to in: supplying position relatively to the inking rolls 6, the fountain roll 2- being then in the path of rolls 6 as the latter are caused to move upwardly.
F ixed upon the shaft 8 is a second collar or ring 55 having acam-portion Rotarily bearing upon this collar 55 is a second roller 5'1, also carried by the rod 53,
as more particularly shown in Fig. 6. llormally, as when throw-ofi" lever 14 is in the position thereof illustrated in Fig. 1 and the platen and type-bed are in operative printing relation, roller 57 is out of engagement with the cam-portion 56 of second collar or ring 55, and the fountain and its roll 28 are free to be rocked relatively to the hiking rolls 6 as heretofore described. TVhen, however, throw-off lever ll is actuated to throw the platen and type-bed out of printing relation, collar with its supporting shaft 3, will be rotarily moved to bring cam-portion 56 thereof beneath roller 57, whereupon the fountain box and its roll 28 will be depressed, against the tension of spring 36, into non-ink supplying position relatively to the inking rollers 6, and held in such position as long as lever 1% is in throw off position, so that, should the press be continued in operation, rollers 6 in their travel will escape any contact with the fountain roll 28.
it may be desirable, as when printing small jobs, to reduce the ink-supplying surface of fountain-roll 28. For this purpose, provide the cover-plate 58 shown particularly in Fig. 9; This plate 58, which is adapted to fit over and upon the fountainbox and its roll 28 as illustrated in Figs. 10, 11.;and 12, is provided with bent end-por tions 59 and 60 slotted transversely, as at 61 and 62, respectively, to accommodate fastening-screws Thus the plate 53 may be adiustably fastened laterally upon the box and more or less of the inksupplyiug periphery of fountain-roll as may be desired. presented for (-nigagement with the inking-rolls 6 as the latter are oscillated or rocked upwardly toward the inking-disk I am aware that changes in the form, construction, arrangement, and combination of the several parts of my new ink-fountain may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.
