Description

UNrrEE STATES PATENT OFFIGE.
WILLIAM H. WOODCOCK, OF WILLIAMSBURG, NEW YORK.
IMPROVEMENT IN DAMPING-ROLLER-S FO R LITHOGRAPHIC PRINTING.
Specification forming part of Letters Patent No. 189,828, dated April 17, 1877; application filed May 9, 1874.
-. To all whom it may concern:
graphic damping-roller. Fig. 2 is a detail view. V This invention has relation to printingpresses wherein the impression-cylindersreceive rotary motion, and the bed on which the form, or the stone, as the case may be,
'is supported, receives a rectilinear reciprocating motion beneath the said beds.
The nature of my invention and improvements consist in a hollow damping-roller or rider, adapted to revolve about its axis, and suitably perforated, in combination with perforated pipes, which are arranged inside of the perforated cylinder, and supplied with water in regulated quantities by means of feed-pipes, as will be hereinafter explained.
It also consists in combining wipers with the internal perforated pipes, for the purpose of evenly distributing the water on the interior surface of the perforated cylinder.
In the annexed drawings, Figs. 1 and 2 show my improved dam ping-roller full y, which isa thickly-perforated cylinder, E, rotated by any suitable contrivance, and containing a number of perforated pipes, P, running from one end to the other 0t 1t, and closed at their ends. Each one of these pipes P is supplied is provided with a cock,j, for regulating the supply of water. The pipes P and J are stationary, and the cylinder E revolves around them. I introduce the water into the pipes P at the middle of their length, so that i't'will flow in two directions. Outside of each pipe P I apply a wiper, g, which may be made of leather or other suitable material, and which is arranged so as to act on the inner side of the cylinder E, as shown in Fig. 3, and thereby distribute the water so that it will flow evenly through the perforations in the cylinder.
By means of this damping-roller I am able to uniformly dampen the surfaces of cloth-covered rollers, which apply the moisture to the form or the stone, as it reciprocates beneath them.
Since the filing of this specification a patent has been granted to me in England, which I bears date April 14., 1875. r
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A revolving perforated damping-cylinder, E, in combination with stationary perforated pipes P and feed-pipes J, substantially as described.
2. Wipers g combined with stationary pipes P and revolving perforated damping-cylinder E, substantially as described.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
WILLIAM HENRY WOODCOCK.
