LIFTER DESIGN MACHINE.

Application filed May 7,

This invention relates to means for producing a design in a web of paper. This design may be produced by preferably wetting the paper and longitudinally corrugat- 5 ing it by means of a pair of annularly grooved rolls. one of which is lifted at intervals in order to produce a design in the paper web.

In the drawings Figure 1' represents a plan view and Fig. 2 a sectional view of the machine taken 011 the line 2-2 of Fig. 1.

10 and 11 show the frame of the machine, suitably tied by braces 12, 12. 13 shows the roll of paper, from which it passes over the 15 guide roll 14, and under rolls 15 and 16. and into thetank 17 where the paper is wetted. The wet web of paper 18 then passes upon the cylinder 19 which is annularly corrugated at 20. The paper then passes around 20 the corrugated cylinder 19 and under the small annularly corrugated roll 24. The cylinder 19 is mounted. on a shaft 25. and driven by gear 26, and operated by means of a pulley 27 or by any other suitable means;

The small roll 24 is mounted upon the shaft 29 and is driven by gear 30 meshing into gear 26. i

In order to produce the desired design which is shown in the Web of paper at 32, 30 the roll 24 must be lifted away from cylindcr 19 at intervals. This is accomplished by means of a cam 33, operating a lever 34 that may be provided with a roller engaging the cam This lever 34 is pivoted at 35 35 and the other end of the lever supports the shaft 29, to which the small corrugated roll is connected. The lever 34 is supported in a bracket 36 which is fastened to frame of the stituted.

machine. This bracket 361's provided with two upwardlyextending parts 37, 38, in which the shaft 35 is pivoted. This bracket is also provided with a projecting portion 40 which supports the cam shaft 41. The camshaft 4.1 is driven by means of a gear 42, which engages the cylinder gear 26. The near end of the cam shaftis provided with a spline 43. and a nut 44. screwed, in order that the cam 33 may be removed from the shaft, and another cam having ditterent projections. may replace it. This cam may be provided with as many projections as is desired for lifting the small This nut may be un:

corrugated roll at intervals desired, which may be regular or irregular. The lever 34 is pressed downwardly by means of a spring 45. r y

Thecorrugated roll 24. may be removed from lever 34 and from the arm 46, by removing caps 17 and a newroll may be sub- The new roll may be provided with cut away portions; if desiredto produce modifications ot' the design.

Various modifications may be introduced in the construction of this machine without departing from the spirit of the invention.

l'claiin as my invention:

In a machine for producing designs in paper webs and in combination, a pair of anuularlv grooved rolls between which the paper web is passed whereby the web is longitudinally corrugated, a cam to separate the rolls at intervals to thereby provide alternate corrugated and plain portions in the web. and means to rotate the rolls and the cam.
