IMPROVEID MACHINE FOR 1".A.RR`.II13"G` 'PAPER FOR ROOI'ING, cc.

The Schedule'refen'ed to in these Letters Patent and making part-'of the same.

To all whom. it 'may concern Be it known that I, JOHIN ROBERTS, of Valthain, in the county 0f Middlesex, and State of Massachusetts, have invented certain Improvements in Machines for larring Paper for Roong Purposes, of which the following is a specification, reference being had to the accompanying drawings.

My invention consists in the novel construction, arrangement, and combination of certain mechanical devices in a rna'chine for satura'tiug paper with coal tar, or any other substance or substances for rooting purposes, in such ainauner that the paper may be thoroughly and conveniently saturated bya single operator, as hereinafter explained. 4

In the drawings- Figure l is a longitudinal vertical section of my machine, complete, and

Figures 2, 3, and 4 are views of parts detached, and Figure 5 is a cross-section ou the line a.' x, ot'iig. 4.`

In constructing my,` machine, I make a suitable frame, A, of any size desired, and in Open bearings.

At the upper ends of uprights C, at one end ot' this frame, mount a roller, I), havinga loose collar, a, 'as shown in dotted lines in vtig. 2, and detached in fig.`3.

In the opposite end of the frame, I mount a drying friction-roller, I,bound with cord b, or other material suitable for the purpose, hereinafter explained.

Above the roller I, which is mounted in the uprights B, I mount the sword or split-roller E, in Open bearings, so that it may be conveniently removed.

In the same'iialne A, I also mount press-rollers F and G, in bearings c and d, arranged so as to be ad- `instable by setscrews e and f, and to be held in position by levers J, pivoted so as to allow these rollers to be removed, all as clearly shown in tig. 1.

The rollers F and Gare provided with gear-wheels, and are connected with a gear-wheel On the roller I, by an intermediate gear-wheel K, as shown in the same ligure.

Between the roller G and the upright C, I place a frame, H, so arranged as to slide vertically, in suitable `slots or guides attached to or in the sides of the frame A, and having connected to the lower end of eachV of its sides curved pieces L, in which are three rollers, y, h, and i, and having 'its sides provided with holes It', for setting it at diiierent heights, as desired.

In operating my machine, thus constructed, I placeit over any receptacle, M, suitable for receiving the coaltar, or other substanceV to be heated, and with which the paper is to `be saturated, in such a manner that the frame H may carry its rollers g, h, and t into the liquid, and also, so that the drippings from the pressure rollers or other parts of the machine may fall into it. lVhen the liquid is sufficiently heated I take out the roller I), remove its collar a, slide onto it a roll of paper, N, return the collar a, and replace the roller D,

with the roll of paper upon it, in its bearings in the upright C. I then pass the loose end' of the paper under the Vrollers in the lower ends of the frame H,

up through between the pressure-rollers I" and G, andconnect it to .he swordrol1er E, bypassing it between the two parts of this roller, and locking it there. 'As this roller isA divided diagonally, as shown in g. 4, they are fastened together by having their thin ends enter a recess, y, under the collars of the roller, as

shown in figs. 4' and 5. f

When this is done, the machine is adjusted by setting the frame H and the rollers F and G as desired, then by means of a 'single crank, 0, att-ached to the end of the roller I, the whole machine is operated.

The roller I, by means of friction, simply causes the rollerE to turn and receive the paper, while, by means of the gearing, the pressure rollers are operated, and these in turn draw the paper through the hot liquid, around the lower end of the frame H.

The advantages of this machine over those now in i use are many. The paper is rst easily mounted upon convenience in introducing'the paper, and are adjust-v able, so as to suit the pressure to the thickness ot' the paper, or to the character ofthe saturatiug'liquid. rlhe cord, or other material, bound about theroller I serves both to increase its friction and to dry the paper.

VBesides these advantages, the machine may be operated by a single person, and by a` single crank.

I am aware that machines have been made for drawing paper from one roll onto another, through saturating liquids, about -a single .vertically-adjustable roller in the liquid, and then on through guide rolls and over Scrapers. Having filed an application for a patent for a machine containing these devices, substantially', on the 8th of June, 1847, as will be seen bya reference to the recordsot' the Patent Olice, and having used and experimented with such machines from that time tothe present, and therefore, I do not claim such a machine, broadly; but what I do claim, 1S

1. A machine for saturating paper for roong pui`` poses, consisting ot' a frame A, having mounted therein the rollers I), verticallyfadjustable frame H, pro- `vided with therollers g, h, and 1", the movable and ad- 4. In combination', the movable roller D, provided with loose collar a, the vertically-adjustable frame H, with the rollers g, h, and i mounted in its end-pieces Q. The movable and adjustable pressure-rollers F L, and the sword or split-roller E, constructed andarand G, with their loose bearings e and d, when conranged to operate as described, and for the purpose structed and arranged substantially as herein described, set fort-h. and for the purpose set forth.

jnstable rollers F and G, and rollers I and E, all constructed and arrangedw to operate as herein described.
