Application ledscptember 27, 1881.

[o all whom it may concern:

Be it known that I, WALTER SCOTT, of Plainfield, in the countyof Union and State of New Jersey, have invented an Improvement in Dampening and Cutting Paper for Printing- Presvses, of which the following is a specification.

Paper has heretofore been subjected to a spray of water, and it has also passed over a convex table in a dampening-machine, and in some instances the paper has been wound upon a reel pressed by a lrictional device against a revolving drum.

My invention is an improvement upon these previous devices; and it consists in the combination, with the dampening device, of one or more rotary cutters applied in such a manner as to separate the web of paper longitudinally as it passes from the dampening to the winding devices; also, in the frictional device that acts upon the roll to insure greater uniformity in winding the damp paper, and to allow tor the roll of paper being lowered upon the iioor or a table after being wound, and previous to removal to the printing-press.

ln the drawings, Figure l is au elevation of one side of the dampening, cutting, and winding machine, and Fig. 2 is an end elevation of the same.

The frame A of the machine is of any suitable character, the form shown being preferable. At one end of the frame are bearings a for a roller, b, upon which the roll of paper to be dampened is mounted, and there should` be a frictional detaining mechanism applied to the roller to prevent the paper unwinding too fast. The paper passes over the convex table d, and it is dampened by a spray of water from a jet-pipe, c, similar to a gas-burner, and there are to be confining boards or platesf, that prel vent the water scattering laterally upon the belts and other portions of the machinery. I prefer to employ a roller, e, at the edge of the convex table nearest the roll of paper to prevent too much friction on the paper. I also provide a similar roller, h, at the other edge the table d, and over this roller the paper passes as it leaves the dampening-table and is wound up, as hereinafter described. This roller h also serves as a support for the paper while being cut longitudinally.

(No model.)

The cross-shaft 7c is supported 'in brackets on the frame. Itis provided with arms l, having at their ends gudgeons or arbors7 upon which are the rotary knives m. rlhese knives are preferably made of a circular range of lance-points to penetrate and out the paper as the same is drawn along beneath them. The arms l may be placed upon the shaft k in the proper position for cutting the web ot' paper into longitudinal strips ot' the desired width, and the roller h should be provided with narrow peripheral grooves for the knives m to enter in cutting the paper. A crank-arm, a, at one end of the shaf't lc allows the same to be turned and the cutters or knives m moved ont of the way, so as not to act upon the paper when the same does not require to be cut longitudinally.

The shaft z is provided with arms z and a roller, o, upon-which the paper is wound. At one or each end ot the shaft z there is a segmental gear, p, that gears into the pinion q on the cross-shaft r, at the end of which is a crankhandle, s. There is also around the shaft r a. friction-wheel, t, and a friction-ring, u, and adjusting-bolt 3, by which more or less pressure and friction are applied to prevent the sha-itr turning too freely.

The power is applied to the pulley o upon the shaft 4, and there is a drum or cylinder, w, on this shaft 4 between the frames.

The web of paper is passed through themachine and the end wound around the roller o, which roller o and paper are in contact with the surface of the drum to, as shown" by dotted. lines in Fig. l. Upon starting the power and turning on the spray the paper will be drawn along and wound upon the roller oby the action ofthe drum w, and the speed of movement will be uniform, or nearly so, as the drinn fw acts directly upon the paper. In the movement the spray will moisten the paper/ and the knives will out it longitudinally. rlhe friction at t u will cause the required initial pressure of the roll of paper upon the windingdrum fw, and this pressure will be uniform, regardless of the size of the roller, because the segmental gearp has always the same leverage for detaining by the friction of t u the movement of the shaft z, and the swinging of the armsz and roller o upwardly as the roll of paper increases in size will canse more of the Weight to be taken on the shaft z, and only allow a nearly-uniform lamount of Weight to press the paper to the winding-cylinder. When the roll ot' paper has accumulated to the desired eX- tent, the machine is stopped and the ends of the paper properly secured, or a wrapper applied around the roll of dampened paper, if desired; and when the roll is to be taken ont of the machine the crank s is revolved by hand to turn the gears p q and swing the arms z around until the roll'ot' paper is lowered to the door or platform on which the machine rests. After. the roll of paper has been ref moved a roller, 0, is replaced in the arms z" and the parts brought to position bythe crank or handle s for starting another roll.

1 claim as my invention- 1. In a machine for dampeningpap'er, the combination, with the dampeningftable and winding-drum w, of the segmental gear p, shaft z, arms z', pinion q, shaft r, and crank s, substantially as set forth..

2. In a machine for dampening and winding` paper,the combination, with the winding-drum 'w and rolle-r o, ot' the arms a', shat't z, segmental gearp, pinion q, and frictional clamp t u, substantially as specified.

3. The combination, with the damprningtable and Winding mechanism, ot' a roller, h, adjacent to the dampening-table, and the rotary cutting-knife and the arm carrying the same, substantially as set forth.
