5 Patent No. 258,071, dated May 16, 1882.

Application filed January 12, 1882. (No model.)

.To all whom it may concern:

Be it known that I, HERBERT A. JOHNSON, of Medina, Orleans county, New York, have inventeda certain new and useful Improvement in Apparatus for Making Paper Vessels; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had to the accompanying drawings, in which Figure l is a plan of the apparatus. Fig. 2 is a vertical section in line a: 00. Fig. 3 is a diagram showing a side elevation of one of the swin gin gframes that carry the pressin g-rollers. Fig. 4 is an elevation of the forming-rollers.

My improvement relates to apparatus for making tapering or conical bodies of paper vessels-such as pails, Sac-directly from the pulp; and the invention consists in the combination of parts hereinafter described and claimed.

In thedrawin gs, A indicates a frame, which may be of any desired form and construction.

B is a circular felt of suitable size-say eight feet diameter, more or less. This felt is stretched tightly on an iron hoop, a, by which it is kept in position, and in the center it has an eye, b, whichfits on a fixed projecting pin or journal, 0, secured on top of the frame, the felt being thus allowed free movement on its axis.

0 is, a take-up roller or 'cylinderon one side, located in a trough or box, D, and resting under the felt, said roller being covered with wirecloth and serving to take up the pulp from the trough and transfer it to the under side of the felt, when itis then carried around to the forming-roller.

E E are two forming rollers or cylinders on the opposite side of the machine, attached to a turning frame, G, having a pivot,f, resting in the main frame, by which either roller may be turned up to rest under and in contact with the felt. Each of these forming-ro1lers is covered with a removable jacket, g, upon which the pulp is formed as it is taken off from the felt. The several rollers O E E are frustums of cones whose sides are in line with the center of the felt, and they are so set, as shown in Fig. 2, that the roller 0 is horizontal,while the rollers E E are set at an angle, and the felt stands in an inclined position to fit the top surface of the rollers and preserve the necessary stead of two, if desired.

H H are two pressing-rollers, also of conical form, resting on top of the felt and directly above and over the rollers O E. They serve to press down by their weight (or by spring, if desired) upon the felt and hold the latter in contact with the rollers below, and to impart motion to the felt by the frictional contact as the pressing-rollers are revolved.

I I are two swinging frames which hold the pressing-rollers H H, said frames being pivmain frame, which extends over the felt. These frames can be turned up, carrying the rollers with them, as shown by the dotted lines, Fig. 3, thereby removing the pressure from the felt when desired.

K is a shaft resting in the bearings h h and on the same center with the swinging frames. The shaft receives motion by a pulley, k, and band I, which extends to some outside power.

an m are pulleys on the shaft. n nare pulleys on the ends of the pressing-rollers, and p p are bands connecting the pulleys of the shaft and rollers, by which motion is communicated to the latter. One of these bands is crossed to produce proper motion in driving the felt. By this means it will be seen that constant motion may be imparted to the felt in one direction, and the pressing-rollers can be raised at any time without slackening the bands.

In operation the take-up roller 0 transfers the pulp to the under side of the felt, which carries it around and transfers it to the forming-cylinder E or upon the jacket which covers the cylinder. pulp is attained the frame G is turned, bringing the upper cylinder down and carrying the lower cylinder up to its work, and the loaded jacket on the cylinder is then removed and another applied in its place. The pressing-cylinders H H simply impart sufficientpressure to cause the proper adhesion of the pulp and to move the felt.

It will be seen that the deposit of pulp on the cylinder E will be in the form of a pail or other conical vessel, and can be easily removed, and when removed can be finished in any of the known ways. The strip of pulp deposited on the under side of the felt by the take-up contact. A single roller, E, may be usedinoted to bearings I h on a cross-piece, i, of the When the proper thickness of y cylinder is ot'just the right width to cover the forming-cylinder.

By the means above described the bodies of pails and other conical vessels can be formed in a simpler and more effective manner than heretofore, as the felt is a circular disk which simply revolves,and therollers are simplycones which point to the center of the felt.

I do not claim a wire-screen take-up roller, a forming-roller, and an endless felt, such asis shown in the patent of I. B. Taylor, October 24, 1876. e

What I claim as new, and desire to secure by Letters Patent, is I 1. In an apparatus for forming paper vessels from pulp, a circular felt in the form of a disk mounted centrally upon a journal or pin, so as to have a free rotation on its own axis, and serving byits rotation to transfer the pulp deposited upon it by the take-up roller to the formingrolleron another side of the felt, as specified. m

2. In an apparatus for forming paper vessels from pulp, the combination of a circular felt mounted centrally upon a journal or pin, so as to have a free rotation on its own axis, a conical take-up roller on one side and under the felt, which deposits the pulp on the under side of the felt, a conical forming-roller on another side and under the felt, which removes the pulp from the felt and deposits it upon itself, and two pressing-rollers above the felt, resting over the conical take-up and forming rollers, as specified.

3. The combination, with the circular felt resting and turning on a central journal or pin, of the two conical forming-rollers mounted on a frame pivoted to the main frame centrally between the rollers, whereby either roller may be turned up beneath and in contact with the felt when the other roller is turned down,

as specified.

4. The combination, with the circular rotating felt B, mounted on a central journal or pin, 0, of the swinging frame I, carrying the pressin g-roller H, and the band 19, resting upon pulleys attached respectively to the roller H and shaft K, as shown and described and for the purpose specified.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
