PAPER MANUFACTURE.

SPECIFICATION forming part of Letters Patent No. 734,928, dated July 28, 1903.

Application filed March 17,1903. Serial No. 148,191. (N specimens.)

T0 00% whom, it may concern:

Be it known that LWILLIAM W. McEwAN, a citizen of the United States, and a resident of 'Whippany, in the county of Morris and State of New Jersey, have made a certain new and useful Invention in Paper Manufactures; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being bad to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 is a perspective view illustrating the manufacture of the article. Fig. 2 is a detail plan view illustrating the pattern upon the pulp sheet. Fig. 3 is a detail perspective view of the completed article. Fig. 4 is a similar view of the form a.

The invention relates to paper manufactures, and more particularly to manufactures from the wet or pulp sheet; and it consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the letter a, indicates a form or block which is provided, usually, with a central peg or pin 6 in its upward-presenting end and may be attached to a table 0, in such wise, however, that it can be readily detached.

d represents a pattern which is preferably made of waterproof paper, oil-cloth, or other suitable material. This pattern should have a central aperture e. It is provided with the slots f, which extend from the central portion in radial or approximately radial directions. These slots are formed in pairs and serve to indicate lines of folds'or laps of the wet paper or pulp sheet in the manner hereinafter described.

g indicates a sheet of paper-pulp from which a vessel--such as a vase, a basin, a jardiniere, or other like articleis to be made. Upon this sheet of pulp-paper the pattern is laid, and its position being fixed by means, of a peg or pin passing through the aperture 6 lines are marked through the slots on the pulp sheet with a dull blade, which serves to crease the pulp without cutting it. Then the pattern being removed the sheet of wet pulp is transferred to the block a and is centered thereon by the engagement of the central aperture with the peg or pin I) of said block. The pulp sheet is then manipulated as it hangs down over the form, and with the aid of the pattern-creases lapping folds are made insuch regular manner as to form an ornamental feature. At the same time the inner walls of these laps or folds are brought into intimate contact and the laps or folds pressed down upon the block, so as to make these parts almost solid. The article having been properly shaped on the block is left thereon until it is dried in form, and then the block being removed the article can be coated with paint or other ornamental covering and varnished. It will be found very hard and durable and may be waterproofed for use in holding wet earth or liquids, if desirable.

lVhen the article to be made is a jardiniere or vase of bulging or swelled form, it is necessary to remove it from the block before the material is so dry and rigid that it cannot be readily flexed. lNhen partly dried, the laps at the neck or narrower portion can be made to yield sufficiently to facilitate the withdrawal of the block, after which the neck or narrower portion can be pressed back toposition upon a suitably-shaped ring or disk, which is designed to remain until the article is dry, when the ring or disk is removed and thearticle finished. Pedestals and vases may be made in this way, and these, as well as the vases, jardinieres, and disk-shaped articles designed to'be strong and serviceable. Being very light, they are easily transported, and as they are not liable to fracture it is believed that they will serve very useful purposes.

As square sheets of pulp are most economical, the laps are usually made on the corner diagonals, and the edges of the article after it has been partially dried are shaped in such ornamental fashion as may provide a suitable finish to the general design.

Having described this invention, what I claim, and desire to secure by Letters Patcut, is-

1. The process of making paper articles from a wet pulp sheet,which consists in creasing the pulp sheet in substantially radial lines, lapping and folding the sheet upon the I creases, and having shaped edges,'an'd wet-ercreases to the desired form, shapingrthe edge proofed and coated, substantially as specified. 10 of the sheet so lapped and fitted, drying the In testimony whereof I affix my signature same, and finishing the article by waterproofin presence of two Witnesses.

5 ing and coating, substantially as specified. WILLIAM W. MOEWAN.

2. A paper article consisting of a sheet of Witnesses:

paper-pulp creased in substantially radial 1 WILLIAM A. PoLHEMUs, lines, lapped and folded to form upon the F. S. DRAKE.
