FIG Q NEI ES= m lmrm UNITED STATES PATENT OFFICE.
GRENVILLE M. STEVENS, OF DEERING, MAINE.
PULP-MAICHINEQ SPECIFICATION forming part of Letters Patent No. 333,428, dated December 29, 1885.
Application filed March 17, 1885. Serial No. 159,148. (No model.)
To on whom it may concern:
Be it known that I, GRENVILLE M. STE- watts, of Deering, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Pulp-Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.
Figure 1 is a side sectional elevation. Fig. 2 is an edge view of the vessel h when opened.
Same letters show like parts.
My invention relates to machines for forming pulp into different forms, shapes, and vessels, such as pails, bowls, pans, pulpboard, 850.
My machine is rotary, and revolves on the vertical shaft a, with a step or socket, b, to receive the lower end of the shaft.
0 is a pulley on which to receive power.
The forming-machine I have shown in the drawings exhibits a conicallyshaped vessel, in which the pulp is placed; The pulp is in-. troduced through the aperture d in the concave circular cover 6. The shaft (1 is rigidly connected with the base f, so that the revolution of the shaft rotates the base. The base has a circular flange, g. This receives the lower end of the vessel, makes a close joint, prevents leakage, and holds the vessel in place. The vessel h is provided with numerous small perforations, to admit of the water which is mixed with the wood pulp flowing away and out of the machine. These perforations are throughout its entire extent and as closely placed as practice may require. The concave circular cover has a double flange, z'j-i to rest on the top edge of the vessel h, the other to lap down over the top edge a little, as illustrated. The flat part t of the double flange has ahole in it, through which passes the rod k, with a nut, Z, which bears against the upper side of the flat part 2'. Tnis rod passes down through the base f, and is there held by another nut, m. This rod has a joint at n. Inside of the vessel h,I place first a cylinder or netting of fine wire or any similar perforated article that will answer the purpose, which is to hold or aid to hold the pulp in the machine and let the water strain off. Inside of this I place a cheese-cloth, so as to cover the whole interior, or any like substance. o is the netting; p, the cheese-cloth.
I then introduce the pulp, properly mixed with water. The rods are screwed down, so as to properly hold the cover, the vessel h, and all the parts together. Rapid rotation is then given to the shaft a, as described. The pulp is thrown by centrifugal force evenly against the sides of the vessel h on the inside, forming the sides of a vessel of the same shape as the vessel h, and of a uniform thickness. It is also, when dry, found firmly compacted and strong. It makes excellent light and durable domestic vessels of various kinds. Vessels of artistic shape can also be formed in the properly-shaped molds.
The vessel h is composed of three curv parts hinged together to form, when united, a complete vessel. (See Fig. 2.) When an operation is complete, remove the outer vessel, then the wire gauze or netting, then the cheese-cloth, and the formed article is relieved of the machine and ready for drying; or it may be allowed to dry in the machine. The office of thejoint a is to allow the rod to turn down when. the machine is being taken apart. (See Fig. 1.)
It will be understood from the drawings that although spoken of in the singular number there may be as many rods as necessarytwo or more.
By having, instead of the cheese-cloth p, an inner lining pervious to water and pro vided on the inner side with figures and designs, the sheet of pulp or the vessel formed in the machine may have ornamental designs formed thereon.
What I claim as my invention, and desire to secure by Letters Patent of the United States,
The machine for forming vessels from moistened pulp, consisting of the rotary base f, the perforated vessel h, composed of three parts, and having netting 0 and cheesecloth p, the cover 0, with its flanges iandj, and the jointed rods 7c, the whole .to rotate as herein set forth.
In testimony'that I claim the foregoing as my own I affix my signature in presence of two witnesses.
GRENVILLE M. STEVENS.
