T o all whom t 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 London 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.

My invention 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 nioistening the same, also providing a static discharge through a moistened wick contact.

The object of my invention is to provide means for bringing the paper and dissipator into and out of coaction and more particu? If the nioistening wick of the dissipator should be left in its operative position in contact with the paper when the press is still, it would saturate the paper to such a degree as to materially weaken or break it. My invention contemplates means for avoiding this trouble.

A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 represents in side 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 improved static electricity dissipator, the parts being shown in full lines in their operative position" and in dotted lines in their inoperative position, Fig. 2 is a transverse vertical section jii.

taken in the plane of the line A-A of Fig. l,

Fig. 3 is an enlarged detail longitudinal section showing' the moistening wick fountain, and

Fig. 4 is a transverse section taken in the plane of the line B-B of Fig. 3.

The printing press starter is denoted by 1, whichstarter 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, on its way from the press to the formers 6 of the folding machine.

The-moistening wick is denoted by 7 and its fountain by 8, which fountain is provided with end trunnions 9 mounted to rock -in suitable bearings 10 in the main frame Liquid is supplied from a stationary reservoir 12 mounted on a bracket 13, through a feed pipe 14 having an axially arranged branch 15 leading through :one of the trunnions 9 into the fountain 8.

The moistening wick 7 is moved into and out of contact with the web 2 by electrically operated means under the control of the printing press starter, which means is herein shown as an .electro-magnet 16 of the solenoid type connected to the printing press starter 1 through the wires 17, 18. l

The armature 19 of the electro-'magnet is connected by a rod 20 to an arm 21 of a counterbalance lever fast on that one of the trunnions 9 of the fountain 8, the other arm` 22 of which lever being provided with a weight 23 tending to move the moistening wick 7 away from its operative position by rocking the fountain 8. The armature 19 is provided with an arm 24 which is arranged to engage a stop 25 on the main `frame for limiting the movement of the -moved out of its operative position in con- .tact with ythe web 2. When the controlling' lever 27 is moved into'position to start the press, the electro-magnet 16 will be energized thereby moving the moistening wick against the influence of the-counterbalance weight into its operative position in contact with the web 2. The electro-magnet 16 is prei"- erably so`connected to the printing press starter that the magnet will not be energized until after the press has attained a speed sufiiciently high to prevent the saturation of the web by the contact of the moistening Wick therewith until the web has attained the desired speed.

It is obvious that the means shown herein for automatically bringing the web and dissipator into and out of coaction is only one of many different 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 also shown this invention in connection with a running web, it is to be understood that I wish to include sheets as well.

What I claim is:

l. An electric printing press starter, a static electricity dissipator for the web Comprising a moistener, an electromagnet controlled by the starterand means operated by the electromagnet for moving the moistenerinto and out of contact with the web.

2. An electric printing press starter, a static electricity dissipator for the web comprising a moistener, an electromagnet controlled by the starter and means operated by the electromagnet for automatically moving the moistener into contact with the web when the web is running and for moving the moistener out of contact with the web when the web is not running.

3. A static electricity dissipator for webs comprising a moistener, means for normally holding the moistener out of contact With the web and an eiectromagnet having its armature connected to said means7 for moving the moistener into contact with the web when the magnet is energized and means for energizing and denergizing the magnet.

4. An electric `)rinting press starter, a static electricity dissipator for the web comprising a moistener, means for normally holding the moistener out of contact with the web and an electromagnet controlled by the printing press starter and having its armature connected to said means whereby the energization ofthe magnet will move the moistener into contact with the web.

5. A static electricity dissipator for webs comprising a moistener, a weighted lever for normally moving the moistener out of contact with the web and an electromagnet having its armature connected to said lever tor moving the moistener into contact with the web when the magnet is energized and means for energizing and de'e'nergizing the magnet.

6. An electric printing press starter, a static electricity dissipator for the web coinprising a moistener, a Weighted lever for normally moving the moistener out of contact with the web and an electro-magnet controlled by the printing press starter and having its armature connected to said lever whereby the energization of the magnet will move'the moistener into contact with the web.

In testimony, that I claim the foregoing asmy invention, I have signed my name in presence of two witnesses, this thirtyfirst day of March, 1913.
