IMPROVEMENT IN MACHINES FOR FINISHING PRINTEDPPR.

Specicath n forming part of Letters Patent N0. 146,605, dated January 20, 1874; application filed Fi binary 6, 1873. .i

i To all whom 'it may concern:

Be it known that I, JAMES MORRIS, of Liverpool, in the county of Lancaster, England, have invented certain Improvements in i and connected with Machines for Fnnslnng Printed Sheets, of which the following is a specification The object of this invention is to properly chines or apparatus for which British Letters `12a-tent No. 1,7 46, of the year 1865, were granted to methat isv to say, machines so constructed that to facilitate finishing the printed sheets of paper are passed through, between, and in -direct contact with, rotating smooth rolls called set-off rolls, and consists, first, as means for coating the ink set-off on the rolls uniformly with Whiting or other powdery matter, in giving a vibrating or joggle motion to the container in suoli manner that the whiting or other matter is caused to escape therefrom and reach the rolls in a shower. Tappets, iitted on a rotating shaft arranged to act on jointed levers carrying a perforated container, arewell adapted for this purpose. Second, as means for insuring` that only Whiting or other l powdery matter of sufficient fineness reaches the rolls in the required quantity, I inclose the said whitin g or other powdery matter in a bag made of textile fabric, and place the said bag in a perforated or open-work container, made to vibrate in accordance with the above first part of my invention. Third, as means for of about the same diameter, bound together on a spindle by end clamps. Fourth, to keep the take-off bufng-rolls, constructed as above described, or take-off rolls of any kind, clean,

I employ for each such roll a cleaning-brush, made of bristles or strong fibers, such brush being caused to rotate in contact with, but-in `the opposite direction to, the take-off rolls, or

at a greater or less surface speed;

erably made hollow, and heated by steam-'-` say, through the pipe 3; 4, 'weighted lever for regulating the pressure of the top set-off roll 2 ,.5, whiting or other powdery `matter containers, forlned with perforations. Vibrating `motion is given to the said containers bythe gravity-levers 6, the inner ends of which are acted upon by the teeth of the wheels 7 Tappets can be employed for giving motion to the containers. carried in theeontainers 5 5 9, buing-rolls, made of disks of calico or other fabric, bound closely together by the nut-clamps l0, the said bung-rolls rotating in the direction shown by the arrows. ferently, although I prefer the arrangement shown, the object in all cases being to cause these rolls to move in the opposite direction to the set-off rolls 2 at the surfaces of contact, or to cause them to move at a higher surface speed. In all cases, I prefer that the surface speeds of 9 should be greater than the surface speeds of 2. 11 show intermediate wheels for giving motion to the buing-rolls 9 and cleaning -brushes 12. The `cleaning brushes are Ymade to move with a greater surface speed at their circumference than the speed of the surfaces of 9. They may rotate in either` direction relatively to the bung-rolls-S), although I prefer that they should move in the opposite direction. 13 are take-off rolls. They are specially useful when highly-sized dampqpaper` is being passed between or finished by the rolls 2. 14 are casings, with pipes 15 leading to an exhaust-fan for drawing away the dustymatter, which otherwise would adhere to the surfaces of the rolls 2 or pervade theatmosphere of the printing-ofce; 16,feeding.and examining doors.

I claim as my inventionl. Coating the ink set-off on the rolls by Whiting or other powdery matter supplied in 8, bags, made of woven fabric,l

They-may be made to move difstantialiy in the lnauntr and for the purpose3 set forth.

Iu testimony whereof I, the said JAMES MORRIS, have hereunto set my hand this 30th day of December, in the year of our Lord one thousand eight hundred and seventy-two, in the presence or' two subscribing Witnesses.

JAMES MORRIS.
