INK-SUPPLY CONTRIVANCE.

Specification of Letters Patent.

Patented Apr. 1'7, 19117.

To all whom it may concern:

Be it known that 1, JAMES E. DOYLE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and use ful Improvement in Ink-Supply Contrivances, of which the following is a specifica tion, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

This invention is associated more particularly than the title indicates with mechanism for accomplishing a uniform distribution of ink. As such it serves as an interrelated aid to the function of the vibrator now commonly employed upon the saddles of presses of the Gordon type.

Heretofore, in so far as I am aware, that form roller which is in advance during the upward movement of the saddle has barely just touched the fountain roller and accordingly received only a narrow streak of ink therefrom. I have contrived-to interpose between this form roller and the fountain roller what is similar in function to the duct roller, in use upon presses of a different type, so contriving the movement of the latter by automatically operating mechanism, as to in sure the most efficient results.

One feature consists as already stated of a duct or intermediate composition roller that moves between and alternately rolls against the upper form roller and the fountain roller. The intermediate roller is carried upon two small arms fastened to a pivotally mounted bar. This roller is carried up by the advance form roller, and held for an interval by an automatically operating locking device and presently automatically released against the action of a suitable restraining device. Vhile the intermedian form roller is held against the fountain roller it is automatically rolled upon it through any predetermined are depending upon the adjustment which was made. Such adjustment is made by altering the throw of an actuating rack which swings with the carriage. My invention includes also an eccentric mounting of the carriage pivot which enables the operator to .limit the upward swing of the carriage and hence the upward travel of the saddle,

whereby the impression is thrown 05 the press.

. On the downward travel of the form roller, and during the interval that the intermediate roller stays against the fountain roller, it revolves with the fountain roller and receives a fresh supply of ink by transfer from it. Just before the finish of the downward travel of the form roller, the intermediate roller with its supply of ink automatically releases from the fountain roller, and drops to a point about halfway over the ink plate. A restraining plunger eases up this release action. Here it is held until the top form roller reaches and rolls it back to the fountain. In rolling back the duct roller revolves with such form roller, giving the latter a supply of ink on the upward travel. This offers the advantage of not only supplying but also distributing the ink to the form roller on the upward stroke of the saddle as well as merely on the clownward stroke as heretofore. By the time therefore, that the form rollers reach the form the ink is more thoroughly distributed in corresponding degree. The action of the intermediate roller is to successively revolve with the fountain and form rollers to transfer the necessary supply of ink from the former to the latter.

A particular advantage of my invention is that the supply of ink from the ink fountain can be readily controlled so that the ink may be deposited over a considerable area of the intermediate roller as thin film, The rack at the side of the press can be adjusted so that the intermediate roller will be covered with the desired thin supply to any extent that may be necessary to supply the form. hen the impression is throu n off the press by means of the eccentric, the intermediate composition roller is not car ried up to the fountain, hence it is not needlessly given a fresh supply of ink.

The inventive conception is associated with means which are hereinafter explained and variously combined in the claims. \Vhile the annexed drawings and particular description thereof, set forth the preferred form embodying my invention, it should be understood that the means only exemplifies one of many diversified mechanical forms with which the principle of my invention may be properly applied.

Figure I is a side elevation of the upper portion of a Gordon type of printing press equipped with my ink supply contrivance and showing the saddle approaching the ink fountain.

Fig. II is a view similar to Fig. I with certain parts broken away and showing the saddle in its uppermost position and certain other parts in correspondingly altered positions.

Fig. III is a View like Fig. II with the exception that the saddle has traveled clownwardly some distance away from the fountain, fewer other parts having altered their positions.

Fig. IV is a somewhat more comprehensive view in side elevation to include the relative location of the type-form and showing the saddle in a position just short of the limit of its downward travel. The position of certain intermediary parts is further altered in this view, while one unitary detail is shown in both of its extreme positions one being indicated in dotted lines.

Fig. V is still another such side elevation showing the carriage swung off center such that the extent of'upward travel of the saddle is limited, the extreme upward position under such circumstances being illustrated in this view,

Fig. VI is a rear view of the near side of that portion of the press embodying my invention with the parts in the position seen in Fig. I.

Fig. VII is a section on line VII-VII of Fig. VI looking in the direction of the arrows.

Fig. VIII is a top plan of the entire uppermost portion of the press.

Fig. IX is a section on line IXIX of Fig. I.

Only so much of the supporting frame of a Gordon type of press is shown as either directly supports or actuates the parts in conjunction with which my inventive improvement functionates. Furthermore but one saddle has been included since sufiicient for the purposes of this application.

A portion of the main supporting frame 1 carries rearwardly and on opposite sides a pair of journals 2 in which a bar 3, having within such journals off center portions 1, is mounted. A pair of primary actuating rods 5 one of which is shown in several of the figures as pivotally connected to one end of the bar 3 serves to actuate certain parts in synchronism with certain other parts. A pair of connecting rods 6 are pivotally connected to opposite rear edges of the swinging carriage 7 and are adapted to control distinct relative movements of the carriage. The rods 5 and 6 have been broken away and a further description of their function is unnecessary since long known and now common to the art. A short crank 8 is fixedly secured in any approved manner to the middle of the bar 3 and articulating with the extremity of this crank is a connecting rod 9 leading to the fulcrum of an operating lever not shown. When an upward movement is imparted to the rod 9, the purpose of the off center portion 4 is utilized whereby the impression is thrown ofi the press, as purposely illustrated in Fig. V. Such action serves to move the pivot of the carriage 7 rearwardly and hence tilts the top of such carriage forwardly and in consequence precludes an upward travel of the saddle to the same extent as is possible and only desirable when the press is printing under operation. A pair of spring controlled saddle arms 10 are mounted in any suitable manner at opposite sides of the carriage 7 and pivotally connected to and extending therebetween, is a saddle 11 carrying inking rolls 12, and above a vibrator 13. A conventional design of saddle has been illustrated and no further description of its movement is required since likewise very familiar to those conversant with this particular art.

The frame 1 is moreover fashioned at opposite sides with pads 14: and supported thereon is an inverted U shaped bracket 15 having outwardly projecting extremities 16 which are actually seated upon said pads, as clearly shown in Figs. VI and VII. An upper intermediary portion 17 of the bracket 15 is provided with an opening 18 through whichthe center pin 19 of an inking disk 20 projects. Secured at opposite ends of the upper surface of the portion 17 as by screws seen in Fig. VII are a pair of brackets 21. These brackets project rearwardly and their free extremities are fashioned with alined bearings 22 in which a rod 23 is mounted. This rod projects laterally beyond each of the brackets 21 and has its ends squared, as shown for example in Fig. I. Another pair of brackets 24% having inturned lower extremities 25 adapted to rest upon the extremities 16, extend upwardly to support a track continuation 26 of the upper side edges of the frame which are laterally adjacent opposite sides of the type-form as clearly shown in Fig. IV. roller track 26 at one side is a rack 27 seen in Fig. VIII. A direct operative engagement with this rack insures a positive drive of the vibrator 13 as shown and described in Letters Patent issued to me June 2, 1914, No. 1,098,432. Secured to the brackets 24. somewhat rearwardly of their median transverse planes and below their portions 26 are bumpers 28 having their rearward edges rubber covered. The purpose of these bumpers will be later explained.

The upper extremities of the brackets 24 are provided with elongated longitudinally Extending along the 2 30 extend to adjustably secure a fountain 31 which extends across and rests upon the up per surfaces of the brackets 24. The fountain 31 itself is not new and as such includes in its rear wall a plurality of alined thumbscrews 32 adapted to adjust a partition 33 therein. The fountain 31 is well shown in Figs. VI and VIII. Directing attention to Figs. VIII and IX, the end walls of the fountain will be seen to mount a shaft 34 which has one end 35 projecting outwardly some distance beyond the near end wall as seen in the majority of the views. Between such end walls of the fountain 31, the shaft 34 carries fixedly the usual fountain roller 36. A part of the projecting portion 35 of the shaft-34 carries a hollow gear 37 having a hub 38 and teeth 39. Pivotally mounted and circumferentially arranged in the gear 37 are a number of pawls 40 adapted to gravitationally engage the teeth of a ratchet 41 which is keyed to the extremity of the portion 35. The engagement of the uppermost of the pawls 40 with the teeth of the ratchet 41 can be seen upon inspection of Figs. I to V inclusive. Loosely mounted about the hub 38 as well shown in Fig. IX is a collar 42 having an outwardly projecting extension 43, the extremity of which is fashioned as an undercut guide way 44 having its open side presented in the direction of and in the same plane as the teeth 39. Near the lower end of the guide way 44 and on the front or closed side thereof, is a projecting pin 45 the function of which will be presently disclosed.

Projecting from the carriage 7 rearwardly beyond the bar 3 when the parts are in the position seen in Fig. II is a stud 46 best seen in Fig. VI. Pivotally connected at its lower end to the stud 46 is an upwardly extending bar 47 and this bar is in turn connected at its upper end by means of screws 48 with another guideway 49 which latter has its open side disposed in the reverse direction from that of the guideway 44 as may be seen in Fig. VIII. The forward or free edges of the guideway 49 are fashioned each with a plurality of upwardly alined apertures 50, in any one of which a pin 51 may be inserted. Projecting rearwardly from the upper end of the guideway 49 is a finger 52. A rack 53 corresponding in exterior contour with the interior contour of the guides 49 and 44 is adapted to slide along each of these. As so positioned within the guideways 49 and 44, the teeth 54 of the rack 53 engage with the teeth 39. Near the bottom of its forwardly disposed side the rack 53 carries a pin 55. This pin projects transversely with reference to the pin 51 and intersects the com mon plane of thetwo rows of apertures such that an engagement of one pin with the other and actually of the pin 51 with the pin 55 is possible. At the top of the forwardly disposed side of the rack 53 is another pin 56 and this pin is yieldingly connected with the pin 45 on the upper guideway 44 by means of a tens-ion spring 57. The arrangement of the construction just now described is such that the pin 56 normally engages the upper edge of the guide way 44, the spring 57 assisting gravity to accomplish this result. It is mentioned here that as the carriage 7 swings toward the position shown in Fig. IV, the stud 46 is lifted and hence also the bar 47. As this latter is swung upwardly both the guideways 49 and 44 are swung in alinement with each other about the hub 38 as a pivot, the teeth 54 on the rack 53 in the meantime constantly engaging the teeth 39 on the gear 37 which is mounted on the fountain roller shaft. During the initial movement of the carriage 7 toward the nearly extreme position seen in Fig. IV or in fact in the position shown in Fig. III the rack 53 is merely rolling upwardly around the gear 37. Presently however, the pin 51 engages the pin 55 to thereafter lift the rack and rotate the gear whereby the pawls 40 rotate the ratchet 41 and hence-tho fountain roller through a corresponding arc. The elevation of the pin 51 determines how soon it shall engage the pin 55 and therefore through what arc the gear on the fountain roller shaft is to be moved.

Mounted upon each of the squared ends of the rod 23 is an arm 58 which extends upwardly just outside the rearward exten sions of the bracket 24 and to a point above the plane of the inking disk 20. The extremities of the arms 58 are fashioned each with a bearing slot 59 in which the shaft of a duct roller 60 is mounted. The arrangement is such that the duct roller 60 may describe an arc of movement above the inking disk without however, touching the latter. The edges of the arms 58 are provided with rearward projections 61, the lower projecting corners of which being in turn fashioned with inwardly projecting ears 62 adapted to abut the bumpers 28. One of these ears is well seen in Fig. VI. The rearward upper corners of the projections 61 are formed as a right angled forwardly presented hook 63as is well shown for example in Figs. IV and V. The purpose of these hooks 63 will be presently manifested. Adjustably secured to the outer sides of the uppermost portions of the brackets 24 by means of screws 65 which pass through slots therein, are a pair of pivot brackets 64. These brackets involve outwardly projecting extensions 66 having reduiced extremities upon which bell-crank levers are pivoted. An upwardly extending arm 67 of this lever is yieldingly connected to the bracket 24 by means of a tension spring 68 adapted normally to hold the other arm 69 in a position shown in Figs. I, II, III, and V. The free extremity of the arm 69 is bent outwardly so as to' intersect the path of movement of the finger 52. Intermediately of its extent the under edge of the arm 69 is formed with a catch 70 having a beveled forward edge and a right angled rear edge. The catch 70 is disposed in the same plane as the hook 63 in front of which it is intended to be drawn by the action of the spring 68 after the arm 69 has been lifted against the action of such spring as seen in Fig. IV. In this manner the arm 58 and hence the duct roller 60 are held at the upper limit of their movement at which time the duct roller is to friction-ally engage the fountain roller with a pressure which is determined by the initial positioning of the fountain 31 upon the brackets 24:. Secured inwardly of one of the brackets 24- as appears in Fig. VI is what is in the nature of a dash-pot 71.

v The lower end of the dash-pot 71 which is intended to functionate as a restraining device is secured in any approved manner at 7 2. A crank arm 73 is fixedly mounted to the rod 23 and its free extremity articulates with a plunger rod 7st which carries interiorly of the pot a plunger 7 5. The purpose of this construction is to ease up the gravitational fall of the duct roller when the catch is lifted.

The operation of my ink supply contrivance may be tersely described as follows:

Looking first to Fig. I it will be seen that the rod 5 is pulling in the direction of the arrow which action tends to throw up the carriage 7 and hence the saddle 11 as indicated by the arrow above it. It will be noticed that the advance form roller 12 is engaging the duct roller 60 and is carrying the same up toward the fountain roller. In the meantime also the bar at is being carried downwardly without having any effect upon the rack 53, this latter having assumed its lowermost position. In Fig. II the movement just considered is concluded until the engagement of the duct roller 60 with the fountain roller has resulted at which time the catch 7 0 fell in front of the hook 63. The duct roller 60 is therefore held in this position of frictional engagement with the fountain roller during the initial movement of the carriage 7 in the opposite or down ward direction owing to an impulse along the rod 5 in the direction of the arrow all as seen in Fig. III. With the beginning of such reverse movement the bar 4:7 is swung upwardly until the pin 51 presently engages the pin 55 when the rack 53 is also moved upwardly against the action of the spring 57. Such upward movement of the rack contrives to rotate the gear 37 and therefore the fountain roller is rolled in engagement with the duct roller 60. Thereafter upon the continued upward travel of the bar 4L7 to the position occupied by it in Fig. IV, the finger 52 engages the arm 69, lifts it against the action of the spring 68 and permits the duct roller to fall to the position shown in dotted lines in Fig. IV. Here it again lies in the path of movement of the form roller 12 when the same shall have passed back over the type-form and partly over the inking disk preparatory to a repetition of the operation of the parts beginning as illustrated in Fig. I. It is obvious that when the bar 47 is moved downwardly and therefore the rack permitted to move downwardlywith it, the latter will likewise contrive to rotate the gear in the reversed direction. Such rotation of the gear-does not however, rotate the fountain roller, inasmuch as the pawls 40 will slip over the ratchet l1 and be idle with respect thereto. The mounting of the pivot bracket 64: for the bell-crank lever is made adjustable along the upper extremity of the bracket 9A in order that the catch 70 may occupy exactly the position required to insure of a suflicient frictional engagement of the duct roller 60 with the fountain roller 36. In-

asmuch as the composition duct roller is of I yielding surface the engagement of its hook 63 with the catch 70 is permitted. The view seen in Fig. V has been shown for the sole urpose of indicating the restricted upward limit of travel of the saddle and hence of the duct roller when the impression is thrown off the press by the actuation of the connecting rod 9. It is apparent moreover that the supply of ink which has been taken from the fountain roller by the duct roller will already be transferred from the latter to the form rollers during their upward movement. This offers the decided advantage of permitting the duct roller to partially cut the ink supply before the form rollers lay the same upon the inking disk. In this manner the essential function of the vibrator is measurably assisted and the efficiency which I allege for my invention attained.
