UNITED STATES ARTHUR J. DAANE, OF CHICAGO, ILLINOIS.

VIBRATOR FOR ?RINTI1\TG 'PRESSES.

Application fi1ed Gctober 13, 1921. Serial No. 507,487.

Illinois, have invented a certain new and' useful Improvement in Vibrators for Printing Presses, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

The invention relates to improvements in ink distributing rollers or what is generally known in the printing art as a vibrator which cooperates with the inking rollers of the press to distribute the ink upon them, so that all portions of the type will be properly inked. v

The particular structure forming the basis of the application relates to a means where by this distributing roller or vibrator may be readily attached relatively to the press without necessitating any change whatsoever in the construction of the press, the construction also permitting the distributing v roller to be readily detached from the press to allow it to he cleansed when this is found nece sary. a

It is an object to provide a construction capable oi performing the above function which is adapted to permit of its associa tion and disconnection with respect to the press without/the aid of any tools to accomplish its connection and removal; yet will be securely held with respect to the press without fear ot its becoming accidentally disconnected.

In addition it is an object of the invention to provide a construction which will adapt itself to. and cooperate with various surfaces over which the inking rollers pass during their travel relatively tothe type and source of ink supply, and which will at all times maintain a close contact between the inking rolls and distributing roller or vibrator.

In addition it is an object to provide an adjustment whereby the proper tension'will at all times be maintained between the various parts which cooperate with each other to accon'iplish the desired end.

The

structure employed isparticularly adapted to be associated with the inking rollsaddle in which the ends of the inking roll shafts are journaled, and which in some printing press structures are carried by a swinging frame which travels across the plane. of the type and ink platen. The structure whereby theassociation and disconnection of the distributing roller and the inking rollers is. accomplished is such that it is capable of association with the body of the saddle by being passed over the upper face of this portion and into contact with the body thereof, or may be associated therewithby passing said structure over the end of the saddle into a position which allows the distributing, roller to be arranged between a pair of inking rollers. As'befor-e stated, the structure is provided with a means for maintaining the distributing roller against the inking rollers. This structure also provides a means for! holding the means whereby the distributing rollers'are secured to the saddle in contact with the saddle and thereby prevents, their accidental separation. A variable tension device is associated with this structure, so that the inking roller maybe adjusted to suit various contingencies which may be present or may arise.

I wish it understood that the various structures herein described may be combined with each other or not, depending upon various structures or the desires of the user.

To accomplish the prime object of the invention, which is the association and disconnection of the distributing roll with the inking rollers and saddle or similar-part, without the aid of any tools or the necessity of changes being made in the press by add-7 ing parts thereto for this purpose, includes the use of anextensible element arranged at one or both ends of the distributing roll which is extensible to allow certain parts of its construction to be positioned with relation to the saddle for engagement therewith, and which upon its contraction engages the saddle and cooperates to hold the end of the shaft in position relatively to, the saddle.

In one embodiment of the invention the structure is capable of being extended transso I ' traverse; One of the members whereby the distributing roller is held with relation to the inking rollersis designed to cooperate with a pin or projection which is part of the saddle of the press and is provided to afford a handle or finger piece to manually move the swinging frame which carries the inking rollers. The invention will be explained in detail in conjuction with the accompanyingdrawings, which show various embodiments of the invention and combina- 'tions, it being obvious that other arrangements may be resorted to without departing 7 tion, which may be resorted to, and is adapt from the spirit of the appended claims form ing a'partihereof.

Figures 12 and13, are respectively an end elevation and section of stillanother form which maybe resorted'to. v Figure 1 1, is an end elevation of a structure which is adapted for connection wit-h pin employed for holding the saddle with relation to the swinging frame of ing press.

Figure 15 is a section of Figure 1 1.

Figure 16 is a section similar toFigure the printtaken on line 1515 15, showing the modified arrangement which saddle which engages the opposite ends of the inking roller shafts and is carried by the oscillating frame, These saddles are as before stated, arranged at the opposite ends of inking rollers 10 and 11, and are respectively designated 12 and13. The devices for removably attaching the distributing roller 14: to these saddles '12 and 13 arerespectively designated 15 and 16. One of these devices is designed to cooperate or be 1 attached to a pin 17, which is part of the usual saddle structure and provided to permit the inking rollers and frame to be moved manually when this is desired or found necessary.

The structure illustrated in Figure 2 is designed so that one of the members, such as 15, may be arranged in cooperative rela tion to the pin 17 and the other as 16, in

relation to thesaddle 12 and be removed therefrom., These devices 15 and 16 are each secured to the opposite ends of the shaft 18 upon which the distributing roller 7 p q is mounted for reciprocation; These de-' Figures 5, 6, and 7 are respectively secis provided with a slotted aperture 21 and. another aperture 22, the latter being pro- 7 vided to cooperate with the pin 17 and the former to receive one end of the shaft 18 which is movable in the slot 21 to allow the shaft to reciprocatein the slot. vertically arranged spring pressed plunger 23 is secured to this end of the shaft adjacent the 'vertical'portion 19 and extendsupwardly througlran aperture 24: in the horizontal portion 20 and into a housing 25 which is carried by the horizontal portion 20. A spring 26 isprovided and arranged in the housing and reacts between a shoulder on the pin and the end of the housing. This structure'maintainsthe shaft 18' and the roller 14 in' position against the inking rollers, yet permits the distributing roller to move with relation to the bracket. The opposite end of the shaft 18 is also provided with a bracket similar in construction to thebracket 15, differing however in certain essentials because of the functions it has to perform which are somewhat different from those of the bracket 15. This bracket 16 is constructed to provide the vertical portion 27 and the horizontal portion 28, the slotted aperture 29, the aperture 30 and the inwardly projecting lug or ledge 31, the latter being designed to engage the under surface of the saddle 12, to assist in holding the distributing roll with relation to the saddle.

This end of the shaft 18 extends through the slot and has a pin 32 provided to also engage the saddle. A spring pressed plunger 33 is secured to this end of the shaft and extends therefrom through the horizontal portion 28 and into the housing 34, which houses the spring This spring and its associated elements are provided to perform the same function as similar parts in the structure of the device 15, and in addition allows this end of the shaft to be'moved with relation to the bracket to permit the bracket to be attached to the saddle 12. To apply this structure to a. press the bracket 15 by means of the aperture 22 is passed over the end of the pin 17, extending from the saddle 13. The bracket 16 and the adj acent end of the shaft 18 are moved relatively to each other so that this end of the shaft is arranged adjacent the uppermost end of the slot 29, or in otherwords, these portions are compressed. The entire shaft 18 and roller 14 and the bracket 15 are then moved towards the saddle 12, this position the ledge 81 so thatit will clear the outer sin" face of the saddle and allows it to be pressed transversely of the length of the saddle until the lodge is arranged below the under face of this saddle 12. The pin at this time rests upon or is arranged adjacent the upper face of the saddle and by a slight movement of the shaft towards the saddle- 12, \vhicli is permitted by virtue of the connection of the pin and bracket 15, allows the pin 32 to be arranged adjacent the inner side of the saddle 12 and then moved towards the saddle, arranging it at one side thereof. The vertical part of the bracket 16 is at this time arranged at the opposite side of the saddle and the ledge or extension 31 is then caused to engage the under side thereof.

Upon the expansion of the parts the saddle 12 will be bounded on four sides, respectively, by the pin 32, vertical wall 27, ledge- 31 and the end of the shaft '18, which securely hold the parts in proper relation, yet permits the shaft 18 to be moved with relation to the saddle without fear ofdisconnection. because of the length of the pin To disconnect the device from the press the spect to the saddle until the ledge 31 is free of the under side thereof' When the parts" are arranged in this manner this end is lifted. away or free from the saddle and the entire shaft is then moved lengthwise of the pin 17 towards the end thereof. T he movement of the shaft towards the end of the pin causes the bracket 15 to be disconnected from the pin, allowing thedeviceto be moved from the press. i

- The bracket 16'may be provided with a hooked shaped end 36 or an apertured end 37, and the curved face 36 which engages the intermediate portion of the saddle, as shown in Figures 1.4, 15, and 16, and a re movable pin 88 may be employed to permit the hook to engage it or allow the pin to be passed throughthe aperture. These devices heretofore mentioned may, if so desired, be provided with an adjustable tension device whereby the tension may be varied to suit various conditions which may arise. To provide a structure such as this the housings 25 and 34 will be supplied with. the screw threads'39 and the knurled head 40 which when manipulated varies the tension of the spring contained inthese housings. A set nut ll is also provided for locking these portions in their adjusted position.

In another form of the invention both ends of the vibrator shaft will be provided with a construction whereby the brackets and the shaft and roller may be: applied to the press by passing the brackets over the end of the saddles instead of as previously mentioned. This form is illustrated in Figures 5, 6, and 7. In these structures the brackets 12" are provided with ears or lugs 44L which extend from the body of the bracket, or are arranged below the lower face of the saddle l'llld' tl lti'll. passed over: the end of the saddle into juxtaposition to a portion arranged at about the center of length of the saddle. The bracket being moved into ongagenient with this portion of the saddle, v

with the lugs or extension l4 arranged upon opposite sides of this centrally disposed portion 45 of the saddle. These lugs 44? are arranged relatively to the bracket 12 so that they will pass below the ends 46 of the saddle whenthe bracket is depressed, thereby allowing the extension at? and lugs ll of this structure to be passed over the end of the. saddle and into alignment with the portion 45of the saddle which is embraced by the lugs 44' and engaged by the extension 47 upon the release and expansion or upward movement of the bracket. This extension 4? is provided with a curved face 47% no i v The head of a pin which holds the saddle V to one end of the swinging arm of the press in some instances projects beyond the outer faceof the saddle. Therefore provision is 'made in this bracket .12 for permitting it to be passed beyond or across this pin into position, without interference with the head 'or the end of the inking roller shaft. To

accomplish this the bracket is bent or otherwiseformedto provide a recess 48 which will allow the bracket to be passed over the end of the pin and the end of the shafts of thev inkingrollers even though they project beyond the saddle. To remove this last named structure from the saddle, the shaft and bracket will be moved relatively to each other as previously explained, until the lugsv 4A are brought beyond the lowermost face of the portion and ends 46 of the saddle,

it being evident that when these portions are thus arranged the bracket may be removed from the saddle by moving it endwise relatively to the saddle.

In the structure shown inFigure 10, the bracket is provided with a portion which is hingedly or pivotally' secured to the end thereof, and thereforevmay be tilted or arranged so that it will pass over the end of the saddle.

This hinged or pivoted portion is designated by the numeral 49 it being pivoted at 50 to the bracket and may be also provided the saddle.

with the inwardly extending projection 51, the ends of which project upwardly forming' the upward extensions 52 which engage the centrally arranged portion of the saddleat its lowermost and side faces. To apply this structure, one end of the member 49 is tilted downwardly, relatively to the end of the saddle and passed beyond said end, then tilted upwardly allowing the op posite end to pass, this allows the pivoted member to be arranged or positioned so that it may engage the intermediate portion of In the structure shown in l igure 8, the bracket and ink distributor roller shaft are movable with respect to each other and each is provided with a separate spring oneperforming the function of releasably holding the bracket with respect to the saddle, and

the other ,yielda-bly holds the ink distributor roller against the inking roller of the press,

In this structure the spring pressed element 54 has an end arranged in the housing 55 which is carried by the bracket 56,

A coiled s nin 57 is arran ed in the hous- C :3

ing and reacts between one end of the housing and the shoulder 58 of the spring pressed element. The opposite end of the element 54 is assed throu 'h the aaerture 59 provided in the end of the wibriator shaft 60 and is permitted to rest upon the saddle of the press.

The coiled spring 61 saddle of the inking rollers. spring 69 reacts between the horizontal poris arranged upon the element 54: and reacts between the shaft and the horizontal portion 62 of the bracket 56. The end of the vibrator shaft is projected through the slot 63 in the bracket in a manner similar to that described in the previously explained structures, and this allows the shaft to move relatively to the bracket and the saddle.

This structure may be applied to the sad dle bypassing it over the end of the saddle oracross the'upper face of the saddle as herein before described, and when applied performs the additional advantage of pro viding the proper pressure to the ink distributing and inking rollers of the press, the pressure required to perform this function being less than thatneeessary to hold the bracket with relation to the press.

In another exeinplification of the invention shown in Figure. 9, a flat spring 61 is arranged and secured below the vibrator shaft. The object of this structure is similar to that illustrated in Figure 8, the flat The keyhole passed over the saddle in a manner similar to that described in connection with the structure shown in Figure 1, the enlarged portion of the aperture being passed over the head of the pin, the latter being provided to hold the saddle with relation ,tothe press. Upon the expansion of the elements, Y

thereduced portion of the aperture will-he lio brought into contact with the reduced pow tion of the pin, the head or the said pinpreventing separatioirof the bracket and. saddle. V V

In the arrangement shown in. Figure 17, the plunger 65 is secured tothe vibrator-or inking roller 'shaft '66 and extends through the horizontal portion 67 of this bracket, it being provided with a knob 68 whereby the shaft may be lifted away from the Ihe coiled tionsof the bracket and the shaft and 1nain-.

tains the shaft and the bracket in their proper .positionsduring the operatic-n of the device. This structure also employs an auxiliary spring 7 O which relieves the pressure of the ink distributing roller from the 1 inking rollers of the press. In this structure .a pin 71 is employed and is provided izzu may be applied to the saddle of a printing press by either an endwise or crosswise movement of the roller relatively to the saddle and also that this maybe accomplished without changing the structure of the press which eliminates many inconveniences which the user would otherwise be confronted with.

It is also evident that by providing the inwardly pro ecting portions similar to 31 vwith a curved face such as 31 which contacts with the intermediate portion of the saddle, that, the bracket is permittedto rock relatively to the saddle] under certain conditions, as for instance when the inking rollers pass over the track upon which they operate during the operation of the press.

It is manifest that the structure is simple and relatively cheap to manufacture as many or" the parts may be stamped intoform which materially reduces the cost of.

manufacture.
