2%,- M, v m- United States Patent Q" 3,065,886 INK DISPENSING APPARATUS Harvey D. Smalley, Jr., Perham, Minn. Filed st. 24, 1960, Ser. No. 64,378 2 Claims. (Cl. 222-4005) This invention relates to ink-dispensing apparatus for use with printing presses and more particularly to pneumatic pressure type ink supply mechanism for use in supplying ink to printing press fountains.
An object of this invention is to provide a novel pneumatic type ink-dispensing apparatus, of simple and inexpensive construction, for use in supplying ink to printing press fountains.
Another object of this invention is to provide a novel pneumatic type ink-dispensing apparatus including a pressurized housing having a readily removable ink receptacle disposed therein connectable with the fountain of a printing press in fluid conducting relation therewith to permit ink within the receptacle to be dispensed therefrom into the printing press fountain without any ink directly contacting the interior of the housing, thus obviating the need for cleaning the latter.
A still further object of this invention is to provide a novel pneumatic type ink-dispensing apparatus for use with printing presses and including a pressurized housing for receiving a conventional open-toppedink container disposed therein, the housing having a readily removable cover including means for facilitating quick connection thereof to the ink fountain of a printing press, thus permitting rapid and efficient change of different kinds of ink for use with the printing press.
These and other objects and advantages of my invention will more fully appear from the following description made in connection with the accompanying drawing wherein like character references refer to the same or similar parts throughout the several views, and in which:
FIG. 1 is a diagrammatic end elevational view of the conventional printing press incorporating my novel inkdispensing apparatus;
FIG. 2 is an enlarged vertical section through the inkdispensing apparatus showing details thereof;
FIG. 3 is an enlarged vertical sectional view similar to FIG. 2 through the ink-dispensing apparatus including a slightly modified form of cover attachment means and illustrating a modified ink container disposed therein; and
FIG. 4 is an enlarged vertical sectional view similar to FIG. 4 through the ink dispensing apparatus and illustrating a still further modified form of the ink container disposed therein.
Referring now to the drawings and more specifically to FIG. 1 it will be seen that one embodiment of my invention is shown incorporated in a printing press which may be of conventional construction and includes side supports or standards 11. An elongate transversely extending pick-up or ink-distributing roll 12 extends between and is journalled for support on the side supports 11 for rotation relative thereto. Printing press 11 is also provided with printing rolls 13 and 14 which are also rotatably supported on the side supports or standards 11 and the pick-up and printing rolls are arranged to be rotated at relatively fast peripheral speed in a manner well known in the art.
The uppermost portions of the side supports 11, as best seen in FIG. 1, are provided with brackets 15 each having a set screw 16. A disposable inking mechanism, designated in its entirety by the reference numeral 17 and more fully described and illustrated in my co-pending application, Serial Number 30,512 extends between and is detachably connected to the brackets 15 by means of the set screw 16. This disposable inking mechanism 17 includes Bfiiiliflbh Patented Nov. 27, 1952 ice an elongated substantially tubular fountain member 18 which is formed of plastic material and which has one end thereof closed as at 19. Although not shown in the drawing, fountain member 18 is also provided with a plurality of longitudinally aligned discharge apertures each of which is in communicating relation with the interior of the fountain member. Inking mechanism 17 also includes means for controlling the flow of ink from the elongate fountain member 18 and this means is comprised of a valve mechanism 20 which is in the form of an elongate sleeve formed of flexible impervious plastic material.
This sleeve 20 although not shown in the drawings of the instant application but clearly described in my copending application is provided with a plurality of longi tudinally aligned apertures each being disposed closely adjacent the apertures of the elongate fountain member 18. A plurality of tensioning means in the form of threaded bolts 21 is carried by a fountain member 18 and engages the sleeve 20 for varying the tension on the sleeve which in turn controls the flow of ink through the apertures in the fountain member and thereafter through the apertures in the sleeve in a manner clearly described in my co-pending application.
As clearly described in my co-pending application, the inking mechanism described therein permitted an operator to change from one can of ink to another without requiring the time consuming washing and cleaning operation of the printing press. I have also provided a uniquely constructed ink-dispensing mechanism which permits quick change of the kind of ink for the printing press while obviating the need of a cleaning or washing operation.
This uniquely constructed ink-dispensing apparatus designed in its entirety by the reference numeral 22 includes a pressurized housing 23 which in the embodiment shown is provided with a bottom 24 having upstanding peripheral walls 25 rigidly formed therewith. Housing 23 may be formed of any suitable rigid material such as steel or the like and it will be seen that this pressurized housing will be supported adjacent one side of the printing press by a bracket 11a secured to one of the standards 11, as best seen in FIG. 1. The upper marginal portion of the peripheral walls 25 of the housing is provided with an out-turned annular flange 25a.
Housing 23 is provided with a removable cover 26 having a plurality of over center locking means 27 carried thereby having suitable hooks 27a for engagement with the outturned annular flange 25a of the peripheral walls 25. A gasket 28 is interposed between the cover and the upper edge portion of the peripheral walls 25 to provide a fluid seal thereat. When the cover 26 is secured to the peripheral walls of the housing 23 a substantially closed pressure chamber 23a is defined within the interior of the housing.
A threaded inlet 29 is carried by the cover 26 and is adapted to be connected to a source of air under pressure for supplying air to the chamber 23a. The pressurized housing 23 is also provided with a threaded discharge outlet 30 which in the embodiment shown extends upwardly from the cover 26 of the housing.
Referring again to FIG. 2, it will be seen that an ink receptacle 31 is positioned within the chamber 23a of housing 23 and this ink receptacle is of a size and shape of those normally used in the printing industry. The ink normally used in the printing industry, as is well known in the art, is produced in one to five pound cans and it is pointed out that the container or receptacle 3 1 may also be formed of metal in the manner of the conventional ink cans or the receptacle may be formed of plastic or other rigid material. In the embodiment shown, the receptacle 31 includes a bottom 32 and upstanding peripheral walls 32a and when the receptacle is positioned within the housing 23 the top thereof is ,the chamber 23a. sealing. relation with the housing 23 will also be connected to the conduit branch 36 by means of the threaded inlet, 29 h The air pressureregulator mechanismdO will a removed so that the ink within the receptacle will be subjected to the pneumatic pressure within the chamber23a.- I v L Arr elongate conduit 33, as best seen in FIG. 2, eir tends through the discharge outlet 3% of the housing 23 in fluid-sealing relation therewith. It will be seen that a sealing or packing nut 34 threadedly engages the threaded outlet 30 and urges arrannularv sealing gasket 34:: into engagement with the external surface of the conduit 33 so that a fluid seal is formed thereat and which precludes the escape of air therefrom. It will be noted that conduit 33 extends into the chamber 23a and is in sortable into the ink receptacle 31 so that the ink may flow through the conduit once pressure is supplied to the chamber 23a. Conduit 34 is preferably formed of substantially rigid material such as plastic or the like and projects upwardly from the packer nut 34 as best seen in IG a.v t o A The other end of conduit 34 has acoupling carried in fluid-sealing relation thereby and this coupling 35 is connected to the end of the disposable fountain 18 in fluid-conducting relation therewith.
v Referring now to FIG. 1, it will be seen that the threaded inlet 29 is connected to a conduit branch 36; a three way valve 37 is disposed in fluid-conducting relation with respect to conduit 36 and this valve 37, as described in my co-pending application, also includes a handle actuator 38 for actuating the flow of air therethrough. Valve 37 is also disposed in fluid-controlling relation with respect to a relief conduit 39 wherebyair may be discharged therethrough and is interconnected to an air pressure regulatorvalve mechanism 40 having an indicator gauge 41 associated therewith and which is interposed in fiuid controlling relation with respect to a conduit 42 whichin turn is connected to a source of air under pressure (not shown). The air pressure to the ink dispensing apparatus 22 is controlled by the air pressure regulator 40 and the actuator handle 38 of valve 37 permits the pressure to be turned on and off by moving the same between operative and inoperative positions. I h V k In operation, an ink receptacle 31 having the top thereofremoved will be disposedwithin the chamber 23a of housing 23 and the conduit 34 will beinserted through the inlet 30 of the cover 26 and into the ink receptacle 31. It has been found that when the conduit 33 is extended or ,inserted into the receptacle 31 a substantial fluid seal is formed around the exterior surface of the conduit by means of the packing nut 34 and sealing gasket 34a so that air will not escape from the interior of The cover 26 when connected in be set to permit a predetermined amount of airto flow to the chamber 23a and the actuator handle 3f for valve v37 is moved from an ofi position to an onposition to thereby permit air to how into the interior of housing 23.
This pneumatic air pressure within the chamber; 23a ,will cause the ink within the open top receptacle 31 to flow outwardly'through the conduit33 and into the elongate fountain member 18. The ink will thereafter pass outwardly through the discharge apertures in the fountain and throughthe apertures in the sleeve 20 andonto the pick-up roll 12. If it is desirable to change the kind .or color on the ink, the valve 38 will be moved to an inoperative position and the cover 2 6 of the housing will .be removed therefrom. The ink receptacle 31 maybe quickly removed and a new ink receptacle connected in different kind 'of ink without necessitating the washing of the pressure chamber 23a.
Referring now to FIG. 3, it will be seen that I have provided a different locking or retaining mechanism for securing the cover 26 in sealing relation upon the angular flange 25a of the housing 23, The locking means shown in FIG. 3 is generally designated by the reference numeral 50 and this locking means includes a plurality of elongate threaded elements 51, each having its respective lower end disposed between a pair of radially extending ears 52, fixedly connected to the outer circumferential surfaceof the peripheral walls 25 of the, housing 23. A pivot pin 53 secures the, lower terminal portion of the threaded element 51 to its associate pair of ears 52 to permit the elongate threaded element to swing into and out of locking position with. the cover 26 and annular flange 25d. Actually each of the threaded elements 51 will be positioned within a slot 25b formed in the a'rrnular flange 25a and a registering slot 26:: formed in the cover 2 6 when the threaded element is in locki'ngpbsition and a wing nut 54 threadedly engages the upper terminal portion of the threaded element 51 to cause the cover 26 to be urged into "sealing relation with the annular flan ge 25a. r r r h A modified ink container 6=1Iis shown disposed within the housing 23 illustrated in FIG. .3 and this container includes a lower or bottomwall 62 and upstanding 'p'eripheral wall 62a. :This container is also provided with a cover 63 which is secured to the upper peripheral edges of the peripheralwall 62a and this cover 63 is provided with a pair of frangible knockout-portions 64 and 65;, eachiof which are formed by slightly scoring the cover 63 in annular fashion to, define the respective knockout portions. These frangible portions may also be constructed of the same materials as the cover but having 'a thickness substantially less than the thickness of the cover. This construction of the portions '64 and 65 also renders ther'n readily frangible. In use, the knockout portions 64 arid 65 will be rea'dily'ope'ned or knocked out and the conduit 34 will be extended through the opening 64 while the opening defined by the removed knockout portion 65 will permit the air pre's'sure't'o be passed 'ifito'the interior of the container 6-1 to thereby force the ink fluid upwardly through the tube or conduit 34 in a'rnanner to preclude any spillage of the ink into the interior of the pressurized housing 23. .Again it will be noted that this arrangement permits the pressurized housing to be used successively with containers having different kinds of inks without necessitating the washing ofthe interior of the housing. I 7 7 Referring new to FIG. 4, it will be seen that I have provided a still further embodiment of the ink container which is readily adaptable for "use with my inking mechanism and this container 71 also includes a bottom wall 72 and an upstanding peripheral wall 72a and is adapted to contain a predeterminedquantity of ink therein. Actuallysorne of the inks used in printing vary in viscosity and some types are of relatively'thick consistency. In order to get effective discharge of such from the container 71 through the conduit 34,1 have proyided the container 71 with a'cover 73 having an'upturned annular'flang'e 74 which engages the inner circumferential surface of the container 71 for sliding movernent relative to the upstanding circumferential walls 72a. This cover is also provided with a knockout portion formed of frangible material which defines 'an opening 75 when removed therefrom. A sealing means 76 in the fornr of a small O-ring may be provided to effectively seal the area around the knockout portion. In u-se the cover 73 will be left in place and conduit 34 will be inserted through the knockout portion 75 somewhat in the manner of the container illustrated in FIG. 3. Upon the introduction of air under pressure through the inlet 29, the cover 73will. be forced, downwardly by the air-pressure thus causing the ink to be thereafter forced upwardly outwardly through the conduit 34 and through the ink dispensing fountain. Thus, it will be seen that through the use of my uniquely constructed ink containers and pressurized ink dispensing apparatus inks which vary in viscosity may be readily dispensed without any spillage causing ink in subsequent requirement of cleaning of the apparatus in the event it is desirable to use a different color or kind of ink at some subsequent time.
It will be seen from the foregoing description that I have provided a novel ink-dispensing apparatus of the pneumatic pressure type which permits rapid and quick changing from one kind of ink to another without requiring washing or cleaning of the ink-dispensing apparatus.
It will also be seen from the preceding paragraphs that my unique ink-dispensing apparatus is arranged and constructed so that the ink reservoir is actually comprised of a container in which the ink is shipped thus obviating the need of troublesome handling and transfer of the ink.
It will also be noted that my unique ink-dispensing apparatus also includes ink receptacles having frangible portions for ready breaking thereof to permit the ink to readily discharge for the container when subjected to pneumatic pressure.
It will, therefore, be seen a great saving of time and labor may be obtained through the use of my novel inkdispensing apparatus thus permitting the printing press to be used in a more efiicient manner than heretofore known.
It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the various parts without departing from the scope of my invention.
