Application filed April 2, 1913. Serial No. 758,370.

To all whom it may concern:

Be it known that I, HOWARD M. BARBER, a citizen of the United States, and resident of Stonington, in the county of New Lon don and State of Connecticut, have invented a new and useful Improvement in Static- Electricity Dissipators for Paper Webs or Sheets, of which the following is a specification.

Myinvention relates to improvements in static electricity dissipators for paper webs or sheets, and is directed to that type of dissipator or neutralizer in which the electricity is removed from the web by slightly moistening the same, also providing 'a static discharge through a moistened wick contact. i

The object of this invention is to provide means for bringing the paper and dissipator into and out of coaction, and more particularly to electrically operated means under the control of the printing press starter whereby the dissipator and paper are brought into coaction when the press is running and out of coaotion when the press is stopped. V

This invention is directed more particularly to means for moving the web into and out of contact with the moistener of the dis sipator while my copending application filed of even date herewith, Serial N 0. 758,369 now Patent No. 1,244,015 is more particularly directed to means for moving the moistener of the dissipator into and out of contact with the web.

If the web is left in contact with the moistener of the dissipator when the web is still, the paper will become saturated to such a degree as to materially weaken or break it. This invention contemplates means for avoiding this trouble. 7

A practical embodiment of the invention is represented in the accompanying drawings, in which,

Figure 1 represents inside elevation so much of a folding machine and printing press as will give a clear understanding of the construction, location and operation of the several parts of my static electricity dissipator, the parts being shown in full lines in their operative position and in dotted lines in their inoperative position, and

Fig. 2 is a transverse section taken in the plane of the line AA of Fig. 1.

The printing press starter is denoted by 1, which starter may be of any well known or approved construction capable of controlling the operation of the press. The web 2 is shown as passing around a series of rolls 3,

4, 5, 6, on its way from the press to the formers 7 of i the folding machine. The rolls 3 and 4 are located upon the same side of the web 2 and are mounted in oppositely arranged pairs of arms 8, 9, of a compensating lever pivoted at 10 in the main frame 11. The compensating leveris so mounted that the rocking of the lever will move the positions of the rolls- 3 and 4 to change the path of the web 2, without changing its tens1on. l

The moistening wick is denoted by 12,

and its fountain by 13, which fountain is a supported by the main frame 11. Liquid is supplied from a stationary reservoir 14 mounted on the bracket 13 secured to the main frame 11, through a feed pipe 15 havingga suitable controlling cook 16.

lectrically operated means under the control of the printing press starter are pro .vided for operating the compensating lever to move the web 2 into and out of contact with the inoisteningwick 12.- This electrically operated means includes an electromagnet 17 connected to the printing press starter through the wires 19, 19. The armature 20 of the electro-magnet is connected by a rod 21 to an arm 22 of the compensating lever, said lever being provided with another arm 23 having a weight 24 tending to swing the compensating lever to move the web 2 away from the moistening wick 12. The armature 20 is shown as provided with an arm 25 which is arranged to engage a stop 26 on the main frame for limiting the movement of the compensating lever. A ground wire 27 leads from the fountain 13. In operation, when the starter controlling lever 28 is swung into position to stop the press, the electro-magnet 17 will be deenergized causing the web 2 to be moved away from its contact with the moistening wick 12, by the compensating lever. This is accomplished Without lessening the tension on the web. When the controlling lever 28 is moved into position to start the press, the electro-magnet 17 will be energized, thereby moving the compensating lever against the influence of the weight 24, in a direction to cause the rolls 3 and 4t to bring the web 2 into contact with the moistening Wick 12. The electr c-magnet is preferably so connected to the printing press starter that the magnet will not be energized until after the press has attained a speed sufficiently high to prevent undue saturation of the web by its contact With the moistening Wick.

It is obvious that the means shown herein for automatically bringing the Web into-and out of co-action with the dissipator is only one of many difierent forms which might be shown for accomplishing this result; hence I do not wish to limit myself to the particular means herein shown and described.

While I have shown this invention in con nection With a running Web, it is to be under'stood that I Wish to include sheets as Well. i
