ASSIGNOB T WOODJNEWSPAPER MACHIN- EBY CORPORATION, OF NEW YORK, N. Y., A GORIPORATION OF VIRGINIA U SPRAY CONDENSER FOR PRINTING MACHINES Application filed February 3, 1931. Serial No. 513,118.

The principal objects of this invention are to provide a closed spray chamber in'which all ink sprays of an inking mechanism are forced to be created and to provide for drawing the ink spray away from the chamber through a condenser for separating the ink spray from the air and causing the ink to dri into the bottom of the condenser so that it may be returned to the ink fountain and used again.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing, in which Fig 1 is a sectional view of a part of a printing press showing the inking mechanism and ghe features of this invention in a preferred orm; v a Fig. 2 is a sectional view showing the condenser in a different form, and j v Fig. 3 is a plan of another modification.

In the operation of high speed newspaper printing presses, any two contactin ink carrying rollers tend to split up the i film into small particles where they part- These particles float out through the press room and settle on anything with which they come into contact, causing unsightly appearancesand making the air undesirable for breathing. Obviously the ink s ray is set up at various points in the train 0? ink rollers carrying-the 111k from the fountain to the plate cylinder.

In accordance with this invention, a casing 10 is provided surrounding the ink carrying train of rollers and receiving all the ink spray produced, all the way from the ink fountain roll .11 to the plate cylinder 12. In this way the ink sprays produced, do not get an immediate chance to float out into the air but are confined within the chamber formed by this casing. In accordance with this invention, the particles of ink floating in the atmosphere within this casing are disposed ofby providing a pipe 13 connected with an exhaust fan or the like which draws the air out of the easing into the pipe 13 through a condenser 14. This air is disposed of outside.

The condenser is simply a chamber'connected with the casing 10 to receive the air them. The velocity of this ink-laden air Wlll inking system. Then it is drawn out of the therefrom and provided with a series of vanes or deflectors .16 and 17. These vanes are staggered or otherwise arranged to break up the air currents passing through and all the air laden with ink is forced to pass through be increased and therefore the ink will have i a tendency to separate from the air and be re-liquefied. As the particles of ink strike on the vanes or deflectors, they accumulate thereon and drip down into the ink fountain through a. drip pipe 18. The air coming out through the pipe 13 is very largely separated from the ink and is in a better or poorer condition according to the eficiency of the condenser.

It. will be seen that the ink-laden air is first confined in a large chamber which communicates with all the parting surfaces between any two adjacent rolls of the whole chamber by an exhaust current of air which reduces the air pressure within the chamber and either the means shown or any other means can be used for separating the ink particles from the air. This not only clears the atmosphere in a press-room and removes the ink fumesfrom it, but it avoids the covering of all exposed parts in the press-room with a film, or spots of ink. Furthermore whatever ink is normally wasted in .that way is saved by the employment of the present invention.

Although I have illustrated and described only three forms of the invention, I am aware of the fact that other modifications can be made therein by any person skilled in-the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited in this respect, but what I do claim is 1. The combination with an inking device,- of an enclosed chamber surrounding the inking device, and means for withdrawing the ink-laden air therefrom and re-liquefying the ink to prevent the particles of the ink being carried out into the press-room with the air.

2. The combination with an ink transfer ring device, of a chamber enclosing the path of the ink all the way from one end of the ink path to the other and for receiving all the ink sprays treated thereby, and means for exhausting the air from sa1d chamber.

3. The combination with an inking device for a newspaper printing press, of a chamber enclosing the path of ink all the way from they fountain roll to the plate cylinder and for receiving all the ink sprays created there- 1 by, means'for exhausting the airfrom said chamber, and a condenser in the path of the air currents to receive the liquid particles of the ink and separate them from the'air.

4. The combination with a series of ink- 1 carrying rolls, of a chamber surrounding said rolls and receiving the ink sprays thrown off between them, a condenser havin vanes therein providing a tortuous course between them, and means for exhausting the air from the chamber through the condenser, whereby the air currents carrying ink will be caused to give up their ink in the condenser.

'5. The combination with a series of contacting ink-carrying rolls, of a chamber surrounding said rolls to receive the ink sprays thrown ofi between adjacent rolls, a condenserehaving means for providing a tortuous course for the air, means for exhausting the air from the chamber through the condenser, whereby the air currents carrying ink will be caused to give up their ink in the condenser, and means for directing the ink Q thus collected back into position to be used.

In testimony whereof I have hereunto afiixed my signature.

HENRY A. WISE WOOD.
