T E S teams EDWARD F. DUDLEY, OF OAK PARK, ILLINOIS, .ASSIGNOR TO MIEHLE PRINTING PRESS AND MANUFACTURING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION or mmnors.
INK-DISTRIBUTING-DRUM-VIBRATING MEANS.
Application filed match s, 1921. semi no. 449,512.
To all whom it may concern:
Be it known that I, EDWARD F. DUDLEY,
a citizen of the United States, residing at Uak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ink-Distributing- Drum-Vibrating Means, of which the following is a specification.
In printing-press inking mechanisms, it is customary to use one or more reciprocating, rotating drums in contact with companion inking rollers, the back and forth sliding or vibrating movements of the drum being employed to assure the. even spread and distribution of the ink by working it alternately in opposite directions on the surfaces of the contacting rollers.
It is of advantageand useful to provide simple means for permitting adjustment of the mechanism whicheifeets the reciprocatory movements of such a vibratory drum, whereby the amount or degree of ink spreading or distribution may be readily con trolled, in fact, in some cases, it may be necessary or convenient to eliminate such vibratory travel entirely.
Qne purpose of this invention is, there fore, to supply a simple, eficient, readily-adjustable means, for producing such sliding movements of the drum or roller specified.
In its preferred incorporation in physical form, the invention comprises the employment of two cam mechanisms in series or tandem arrangement adjustable relatively to one another to vary or eliminate the stroke or lengthwise travel of the vibratory drum or roller.
In the associated drawing, throughout the plurality of figures of which the same reference characters refer to like parts, such drawing forming a part of the present specification, a desirable embodiment of the in vention has been presented.
In the drawing:
Figure 1 is a partial elevation and par- ;tial section showing the several cooperating elements entering into the improved construction;
Figure 2 is an enlarged section through the cam-shaft and its cam structure illustrating the means provided'for the angular. adjustment of the cam; and
Figure 3 is a section on line 3.-3 of Figure 2. I
As is fulIyiIIustrated in such drawing, the construction includes a frame with spaced or separated portions 11 and 12 havmg aligned bearings for a rotary shaft 12 revolved from an upright drive-shaft 13 through coacting or intermeshing bevelgears 14 andl.
To this shaft 12 an ink-distributing drum or roller 16 is splined so as to be revolved by the shaft, at the same time being capable of longitudinal or lengthwise movement thereon to assist in its ink spreading and distributing function.
Fixed to the drum or roller is a cam 17 having 'a cam-groove 18, and on shaft 12 is a imilar, angularly-adjustable cam19 with a cam-groove 21 and having in a side face a number of cylindrical holes or recesses 22, 22 arranged in the arc of a circle concentric with the axis of the cam, any one of which cavities is adapted and intended to receive a retaining pin or lug 23 projecting sidewise from a collar "24 splined to and hence, when freed, lengthwise movable on the shaft and normally held against a shoulder of the latter by a washer 25 and a companion 'nut 26screwed on the reduced, threaded, terminal part 27 of the shaft.
By removing or unscrewing the nut Sllfficiently, the collar may be shifted lengthwise of the shaft enough to temporarily withdraw the retaining or holding in 23 from the recess of the cam, thus enab ing the latter to be adjusted or turned on the shaft to a new angular position, whereupon the collar is replaced, the pin-entering a new recess, and the parts are tightened in position by screwing u the nut.
The devlce includes also a bearing 28 1n the stationary frame-work accommodating a sliding, rotary shaft 29 equipped at one end with a roller 30 fixed thereto and enga ing the groove 18 of the drum cam 17.
%n similar manner the opposite end of the shaft has a roller 31 projecting into the groove 21 of the shaft cam 19.
The extent or degree of such reciprocation or to and fro movement of the drum may be varied or controlled by changing or modifying the angular position of the shaft cam on the shaft, and, inasmuch as the two cams thus arranged and operable in series are alike so far as the pitch of their cam grooves is concerned, they can be adjusted to wholly neutralize or counteract their action on the drum, and under such circumstances, which are occasionally desirable, the drum does not vibrate or slide back and forth during its rotation.
I desire to make it plain that I have clearly intended by the specification and drawing accompanying this application to illustrate the invention in the best and most practicable form of which I am now aware, but it is to be understood that the invention includes many variations and modifications of this preferred structure, all of which are included within the scope of appended claims.
I claim:
1. In a mechanism of the character described, the combination of a vibrator-drum, means to revolve said drum, means to reciprocate said drum longitudinallycomprising two cooperating cam devices arranged in series, connecting means coacting with the cam surfaces of both cam devices, and means to adjust said cam devices angularly relatively to one another to vary the le 11 of the stroke of the drum, substantia ly as described.
2. In a mechanism-of the'character described, the combination of a shaft, means to rotate said shaft, a vibrator-drum splined to and slidable on said shaft, a cam rotatable withsaid shaft, a cam rotatable with said drum, and cooperating connecting means between said cams, substantially as described.
3. In a mechanism of the character described, the combination of a shaft, means to rotate said shaft, a vibrator-drum splined to and slidable on said shaft, a cam rotatable with said shaft, a cam rotatable with said drum, operating connecting means between said cams, and means to. adjust'said cams angularly relatively to one another to vary the stroke of said drum, substantially as described.
4. In a mechanism of the character de-. scribed, the combination of a frame, a shaft, means to rotate said shaft, a vibrator-drum splined to and slidable on said shaft, a cam rotatable with said shaft, a 'cam rotatable with said drum, a rod slidingly mounted in said frame, and means on said rod coacting with both cams, substantially as described.
5. In a mechanism of the character described, the combination of a frame, a shaft, means to rotate said shaft, a cam rotatable with said shaft, a cam rotatable with said drum, a rod slidin ly mounted in said frame, means on said ro coacting with both cams, and means to adjust said cams angularly relatively to one another to va the stroke of said drum, substantially as di ascribed.
