TO ALL PERSONS TO WHOLNI THESE PRESENTS-MAY COME Be it known that I,l J. AUGUSTUS LYNCH, ofolston, inthe county of Suffolk, and State of Massachusetts, haveinven-ted an Improved Paper-Dampener; and do hereby declare the same to be fully described in the followingspcciicatiou, .and represented in the accompanying drawings, ot which- Figure 1 isa side elevation, l i I Figure 2 an end view,

Figure 3 a longitudinal section, and

Figure 4a. transverse section of it'.

Figure 5 isla view of its roller, representing the cloth covering thereof as partially removed.A

These figures also represent the dampener as supported in the crotches of a stand, marked A.`

The dampener is to meisten a sheet of paper, or the leat` ot`^a copy-book, preparatory to an impression of a written page being taken thereon .by means of. a press. i A I In the drawings, B denotes a hollow metallic cylinder, provided with journals, L a,'fat its' two ends, to enter corresponding holes in two arms, b b, which project down from the extremes oi' lan arched cover, C. The said cover extends abouty the cylinder, iny manner as represented, and at or near its twoends the cover is bent or curved outward, as shown at "ZJ. A knob or handle, c, lextends up from the-middleof the top of the coifer. Furthermore, there-is connected with the cover, at one end of it, and by means of a link or arm, d, hinged to the cover, asmall tunnel, D, the link also being hinged to the tunnel. This tunnel is constructed so as to straddle and rest on the top surface 'of the cover, and enter two long staples or clasps, e e, projecting therefrom,

as represented in thedrawngs, the whole being sol-as not only to support the tunnel on the cover, but enable the.

tunnel to be turned over away from its seat, and moved so as to carry its noso or tube,f, into a filling-hole, g, in the next adjacent head oi the cylinder. A screw-cap,'7z, screws into vthev said hole, an-d stops it when the cylinder is supplied with water. 'The said cylinder is formed with numerous :tine holes, t', leading through its sides, and also with a series of grooves, 7c,- extending transversely about' its `curved surface, and at-or about at equal distances -asunderg there being one or more of the discharging-holes leading into each of such grooves, Around the-cylinder so made is a covering, Z,of cloth, or some other proper absorbent material. I

The` cover, on each side of the cylinder, extends, nearly down to a level with the lower part of the cylinder. This cover answers to protect the cylinder ifromdust, and'to support it within the stand, and out of contact therewith.

The grooves around the surface ofthe cylinder are channels to hold air, and enable it to pass into the cylindr, in order to facilitate the escape of watertherefrom.' With these' grooves, and their passages leading from them into the cylinder, it has been 'found that the absorbentcovering of the cylinder will be kept evenly saturated, but without them, yor with the holes alone, it will not be Vso,'as, by pressure of it on the holes, it becomes so' jammed into them, in time-as to eifectually stop more orxloss of them, ormaterially impede the escape of water from them.

`The stand A is formed with two crotches to receive the edues ofthe cover, which rest in the crotches, and

support the roller out of contact with them, or with anything below them.

' To use the dampener, the roller, after having b'ecn supplied with water, is to be borne down upon and rolled upon the paper to be wet. V j

The dampener Ahereinbei'ore described 'difers from that which was patented by me, April 27, 1858, and is described-in the United States Patent, No. 20,077, as it has no roller for removing the surplus moisture, nor'A any connection of such roller with the wetting-cylinder by means of a handle or frame. Besides, my patented dampener had no cover, nor any transverse grooves in its cylinder. Neither did it have any means of so supporting the cylinder, when not in use, that the-outer periphery of itsabsor'bent covering should be out of contact with anything. i

I claim, in the above-described new or improved dampener, as my invention, the following; that is to say Ilclaim the combination ofthe lling-tunuel with the cylinder and its cover by means ofthe link or arm hinged to them, and so as to operate therewith, substantially as described.

I also claim the arrangement of the stand with the cover and the cylinder, in manner as dscribed and rpresented.

'I also claim the cmbnuton of the lling-tunnel with the cyl'inder audits cover. 4

J. AUGUSTUS LYNCH.
