IMPROVED PAPER-MAKING MACHINE.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, EDWIN WILMONT, of Laona, State of `New York, have invented certain new and useful Improvements in Paper Machines; and I declare the following to be a full, true, and exact description of the same, reference being had to the accompanyingdrawiugs, and .to the letters of reference marked thereon.

Figure 1 represents a side elevation f my machine.

Figure 2 represents an end view of the same.

Letter A, (lig. 1,) represents a vat, in which the paper-pulp is placed, preparatory to being passed through the rollers. In the side of this vat there is an opening, B, (as shown in red lines,) out of which the pulp is drawn upon the endless belt C. Upon each side of this endless belt, upon the top of the frame, there is placed a. pair of rollers; having a belt passing around them, for tho purpose of acting as a guide to the pulp. Letter Grepre. sents an endless belt or apron, which is made of wire gauze, and which act-s as a carrier to the pulp, conveying it to the rollers. This belt passes over the rollers E and E', and around the rubber roller F. To each side of the fram-e thereis a screw-shaft attached, which is provided with a. nut for the purpose of tightening and loosem ing the belt C. The bearings of the roller E are so formed as to play loosely up and down upon these shafts, so that by moving the nuts,`the belt is tightened or loosened at pleasure. Letters F F represent two rubberrollers, one of which is placed immediately over the other, between which the pulp is passed, for the purpose of having theA water pressed out. Attached to the front et' the frame, at which point the pulp passes from the two rubber rollers, there is placed a small wooden or iron roller, H, over which the pulp passes upwards, in Athe direction of the arrows, over the second roller H', and then between the two top rollers. As the pressure between the two lower rollers is not suilieient to press all of the water from the pulp, it is again passed through a second set of rollers, the top one of which being made of Wood or iron. This wooden roller I and the top rubber roller F have both movable bearings, which work in amslotin the frame, and are governed in regard to their pressure on1the pulp by the screws K K. Attached to each one of these rollers there is a cog-wheel, M, which work in one another, so that when one is set in motion it ,communicates the motion to each ot' the others. Letter L represents a small roller, which presses tightly against the upper roller F, so as to catch the water'that is pressed from the pulp, while p assingbetween the rollers I and F, and"` passes it olf to one sidb.

The advantage of using rubber rollers is, the use of felts is entirely done away with, wihile the elastic nature of the rubber does all that is claimed vfor felt;A while by using the third roller, (iron,) three times the amount of pressure is obtained.

The mode of operation is as-follows: The flow ot" pulp is started from the vat A upon the endless belt C, which conveys it in the direction of the arrows, through theiriibber rollers F. It is then passed upwards so as to pass between the rollers I and F, after which the paper is ready to pass upon the drying cylinder.

Having thus described my invention, what I claim, and-desire to secure by Letters' Patent, is

1. The employment of .two or more rubber rollers, incombination with the endless apron C; substantially as and for the purpose set forth.

2. The rubber rollers F F i'n combination with the metallic or wooden roller I, for the purpose of giving additional pressure to the paper, substantially as and for the purpose set forth.

3. The employment of the rollers H H and L, substantially as and for the purpose described.

4. In combination therewith, I claim the rubber rollers F F and metallic or wooden roller I, substantially as and for the purpose set forth. I

In testimony that I claim the above, I set my signature in presence of two Witnesses.
