11 Claims.

This invention relates to printing machines and particularly to the provision in web, strip or sheet printing machines, of roller means particularly adapted for supporting a freshly printed paper surface without blurring or smearing.

It is a further object of this invention to provide such supporting roller means particularly adapted for engagement with and relative movement with respect to freshly printed surfaces without blurring or smearing the ink on the supported freshly printed surfaces.

It is a further object of this invention to provide, in such structure, permanent surfaces on the roller supporting means for the achievement of the above advantages.

It is a further object of this invention to provide such structure which is of cheap and simple construction, which is durable and long-Wearing and which requires no servicing or treatment during the life thereof.

These and other objects and advantages will appear from the following description taken in connection with the drawings.

This application is a division of my application Serial No. 98,514, filed August 29, 1936.

In the drawings:

Figure 1 is an elevational view of a web or strip printing machine, with attached stacker, for use in which the supporting roller of this invention is particularly adapted for use;

Figure 2 is an elevational view in section of a section of the machine showing, in end elevation, a supporting roller according to this invention in its operative relation;

Figure 3 is an elevational view of a web supporting shaft with a pair of roller means thereon, which roller means are shown in section;

Figure 4 is a similar view, but showing the Web supporting shaft partly in section;

Figure 5 is an end elevation of the shaft and roller structure shown in Figure 4, as seen from the left of Figure 4, looking toward the right; and

Figure 6 is a similar view, but taken from the right of Figure 4, looking toward the left.

Referring to the drawings in detail and with reference particularly to Figures 1 and 2, the printing machine is supported on the table I which i supported by the legs 2 having a shelf 3 rigidly attached thereto. Rigidly attached to the under side of the table I is the electric motor 4 which provides power for operating the machine through the belt 5. The machine comprises a base frame generally designated 6 and a 5! plurality of printing units generally designated I which are superposed thereon and which have common operative connection with the pulley 8 which is driven through the belt 5 by the motor 4. The base frame contains an aligning chamber for the webs 9 which are led therein from 5 the pack Ill supported on the shelf 3. The aligning chamber, shown in section in Figure 2, includes the guide plate I I over which the webs are led into the chamber and the'slidable aligning frame having its side members designated I2, 0 which supports the exterior guide roller I3 and a plurality of interior guide rollers I4 having switch means associated therewith and operative upon exhaustion of the web passing about any roller I4 to cause the motor 4 to be automatically 15 stopped immediately upon exhaustion or breakage of any of the webs 9.

In Figure 2, a single, lower printing unit I is illustrated in section and, as therein shown, it comprises a frame having side rails I5 pivoted 20 on the brace rod I6 which has its ends secured to the sides of the base frame 6. The printing unit has a trackway II formed on each side rail I5 for supporting the rollers I8 and I9 of the carriage. The rollers I8 are rotatably sup- 26 ported upon the brace rod 20 of the reciprocable carriage, while the rollers I9 are supported upon the rod 2I. Reciprocation is imparted to the carriage through the rod 2| by means of links 22 pivotally attached at one end to a rod 2| 30 and pivotally attached at the other end to a sprocket chain 23 which is supported at one end by a freely rotatable sprocket and at the other .end by a sprocket 24 which is fixed to the axle member 25. The axle member 25 is provided 35 with a gear 26 and is adapted for operative connection through other gearing to the motor 4.

It will thus be seen that, when the motor 4 operates, the shaft 25 is rotated to cause travel of the sprocket chain 23 which, in turn, causes 40 reciprocation of the rod 2| to which the carriage is attached. The carriage has side or end plates 21 which are secured in suitable spaced relation by means including the rod 20. The rod 2| is rotatable with respect to the side or end 45 plates 21. At its rear end, the frame of the printing unit I is provided with a web supporting guide roller 28 which is secured at opposite ends to the upper part of the frame and which has associated therewith brake means 29. 50

At the opposite end of the printing unit are guide rollers 28' non-rotatably secured to the shaft 25 and having associated therewith the roller 30 which is adapted to engage the upper surface of the web 9. Associated with this roll- 5.;

7 9 with carriage 32, the brakes 29 and 3i are set er 39 is brake means 3i. The carriage which is generally designated 32 has thereon a swingably .mounted roller 33, beneath which the web 9' is termined amount of ink to the ink transfer roll-v ers 38 which are mounted in the carriage 32. Associated with ink transfer rollers 38-is the spreader roller 39 disposed therebetween and resting thereupon.

Also secured to the top plate 611 forwardly of the ink fountain 36 is the type or printing plate 40. The upper surface of the printing plate 40' forms the printing surface thereof. During the operation of the machine, the webs 9 are led over the respective guide rollers I4 in the aligning chamber and thence over guide rollers l3, guide rollers 28 and through the carriage 32, under roller 33 and over supporting rollers 34 and thence over rollers 29 and into the stacker, generally designated 4|. The carriage is provided with an upwardly directed plate 42 which is adapted to cooperate with the clamping roller 43 rotatably supported at the outer end of the arms 44 which are pivotally secured to the rod 45 extending between lever arms 46 secured to the transverse rod 41.

During operation of the machine, the carriage 32 is reciprocated from left to right and then in reverse direction, as seen in Figure 2, and during the forward motion, or from left to right, the clamping roller 43 is thrust toward the plate 42 to clamp the web 9 to the carriage 32. The brakes 29 and 3| are released and as the car- 'riage proceeds to the right, it carries the web 9 therewith, a predetermined amount, depending upon the adjustment of the releasing means for the roller 43, and then it is released.

At the end of the forward travel of the web to lock the web 9 to the printing frame; and, as the roller 43'has been previously released from engagement with the paper, rearward travel of the carrier takes place independently of movement of the web 9 which is secured in stationary relation by engagement of the brakes 29 and 3| therewith. Upon the rearward movement of the carriage 32, the roller 33 is moved downwardly in such manner as to progressively press the web 9 against the upper face of the printing plate 40.

The rearward movement continues until the ink transfer rollers 38 travel over the ink supply roller 31 of the ink fountain 36. Upon the next forward movement of the carriage 32, when the web 9 is clamped thereto, and is being moved thereby,

the ink is transferred from the ink transfer rollers 38 to the printing plate 49 to prepare the plate 40 for printing an impression upon the under side tion in which the roller 34 is adapted for use. As will be understood from the above description,

the rollers 34 must support the lower side of the web 9 immediately after it has been removed from engagement with the inked face of the type .of the printing plate 40, during the reverse movement of the carriage 32. Inasmuch as the inked impression on the lower surface of the web 9 must then be engaged by the rollers 34, it is necessary that they be so formed as to provide satisfactory support for the freshly inked surface of the web 9 without, however, causing blurring of the printing thereon.

In order that the above described support of the freshly inked surface of the web 9 be achieved, without blurring, the rollers 34are-provided at each end with flanges 48 which are of triangular section, as shown in Figures 3 and 4, and which are provided with line peripheral serrations or teeth49. These serrations provide an interrupted annular supporting surface for engagement with the freshly printed surface of the web 9, and travel of the rotatable rollers 34 over the freshly inked surface of theweb 9 may, therefore, occur without blurring of the freshly inked surface. The body of the rollers 34 is cylindrical and the flanges 48 at opposite ends thereof are formed integrally therewith. The central cylindricalbore 50' of the rollers is adapted for close but axially adjustable engagement with the exterior surface of the roller supporting shaft 35, and at one end opposite end and the extreme ends of the shaft 35 are reduced at 3517. These reduced ends are adapted to be rotatably supported in the side or end plates 3'! of the carriage 32.

In order to provide for adjustably supporting the rollers 34 on the shaft 35, a flat spring member 52 is provided, which has each end 53 thereof turned upwardly and the central portion 54 thereof bowed. One end portion 53 of each spring member 52 is adapted for disposition in a groove 5! in the roller 34, while the central bowed portion thereof is adapted for engagement with the bottom of the groove 35a in the shaft 35.

The

opposite end 53 is adapted to closely engage the shaft 35 against rotation with respect thereto, I

while resiliently maintaining the roller 34 in adjusted position axially of the shaft 35. The rollers 34 are thus axially adjustable on the shaft 35 and non-rotatable with respect thereto.

As above described, the provision of the serrations 49 on the flanges 48 thereof provide interrupted surfaces engageable with freshlyinked' surfaces to support the freshly inked surfaces without blurring thereof. The triangular annular sections of the flanges 48 with the serrations 49 form spaced radial tooth surfaces which remain permanently operative to achieve theabovedescribed advantages throughout the life of the roller. As the roller is formed of suitable metal such as iron, steel, bronze, brass orthe'like, the life thereof is, therefore, substantial.

Due to the fact that the serrated surfaces. of

the rollers 34 are movable over the paper surfaces of the ,webs 9, or vice versa, there is no appreciable friction created therebetween and, therefore, no appreciable wearing away of the serrated surfaces of the roller. 34.";

It is, of course,.to' beflunderstood'that the above. -described use of the principles of this invention merely illustrative andthat the principles thereof maybe applied to various widely different structures for the achievement of the printing machines, multigraphing machines or the like, or typewriting machines, where it is desired to avoid blurring on surfaces recently printed or provided with legible or visible impressed or otherwise applied characters, designs or the like.

It is furthermore to be understood that, while the roller of this invention has been described as formed of metal, it may be formed of other ink resistant materials such as hard rubber, phenolic condensation products, synthetic resins or the like and, where desired, of other various nonrigid or resilient materials.

It will be understood that the above-described structure is merely illustrative of the manner in which the principles of my invention may be utilized and that I desire to comprehend within my invention such modifications as come within the scope of the claims and the invention.
