' To aZZ whom, it may concern:

Be it known that I, FRANK EUGENE KEYES, of Newport, in'the county of Sullivan, of the State of New Hampshire, have invented a new and useful Improvement in Machinery or Presses for Molding Pail-Bodies or Various other Matters from Paper-Pulp and I do'hereby declare the same to be described in the following specification and represented in the ac- IO companying drawings, of which- Figure 1 is a vertical and transverse section of a machine or press embodying my invention, the nature of which is defined in the claims hereinafter presented. Fig. 2 is ahorizontal section, and Fig. 3 is a side elevation, on an enlarged scale, of parts of the tubes E and N, hereinafter described,with the mechanism for moving the tube N downward and upward within the tube E. Fig. 4 is an under side view of the locking mechanism of the fo- 0 formed,and consequently there is little, if any,

danger of bursting the water-proof fiexile or india-rubber bag or hood that surrounds the frustum. I

In Fig. 1 of the drawings, A represents a hollow hood or vessel, in the form, externally, of a conic frustum, or an approximation thereto, it being fastened to and supported on a flat annular base or ring, B, sustained by two or more uprights or legs, B, fixed to a floor, C.

O Projecting upward from the hood A, and arranged concentrically with the head thereof, are two standards, D, between which, axially, is avertical tube, E, that, arranged in a stuffing-box, :0, supported by the hood A, is fixed to and extends upward and somewhat downward from the head of the water-proof, fiexile, elastic, or india rubber hood F, that surrounds a foramiuous metallic hollow frustum, G, fastened to and projecting upward from a circular base, H, having 1ugs a a to slide on guides b, proj ectinginwardly from the posts B.

From the central part of the base H a tube,

I, extends downward and slides watertightwithin a stationary tube, K. A pipe, 0, provided with a stop-cock, d, opens into the tube K, such tubeK being closed at its lower end and there provided with a stop-cock, and in practice is somewhat longer than the tube I. The pipe cis for the introduction of steam, air, or water under pressure into the tube K, for the purpose of forcing upward the tube I, the base H, and the frustum G after they may have been depressed for removinga pail-body from such frustum.

.Near the upper part of the tube I is a closure or partition, 0, above which is a tubular neck,

d, that opens laterally out of the tube I. A

hose, e, leads from the neck 11 to another tubular neck, f, furnished with a stop-cock, g, and

leading out of a pipe, h, which is to be sup-l posed to communicate'with an air suction pump. Opening out of the neck fis a tube, 2', that also opens out of the bore of the tube E.

At its upper end the tube E is closed and abuts against the lower end of a spiral spring, k, arranged in a case on the upper part of the standards D. Above the spring there is screwed into its case a tubular cap or thimble, Z, to bear against the upper end of the spring and to regulate the pressure of the spring upon the head of the tube E. A rope or chain, m, extends upward from the said head and over and partially around a grooved guide-wheel, n, and thence downward, and -is fastened to a toggle, 0, from which, at its lower end or part, a stud, 12, extends and slides freely within a slot or groove, q, made lengthwise in a lever, M, which is fulcrumed to a bracket, 1', fastene'd'to the base B. When the lever hangs downwardly from thebracket, the head of the hood F will be drawn and held up to that of thefrustum A. On turning upward the lever the tube E will be free to move downwardly, as occasion may require.

\Vithin the tube E, lengthwise thereof, is a pipe, N, which at its lower end is closed, ex-

cept in having one or more holes, 8, leading laterally out of it, just above the closure t. The tube N at its upper part is bent laterally at a right angle,and extends through vertical openings or slots in the tube E and standard D. Leading into the tube N is a hose, a, that communicates with a pipe, 22, for supplying the machine with the stock or paper pulp.

IOO

freely on a screw-bolt, b, that goes through a short vertical slot, 0', in thetube E and screws into the tube N. A handle, d, projects from the slotted collar 10, which bears at its top against the bottom of the collar *0, and also at its bottom against the top of the collar 00. On taking hold of the handle 02 and turning it one way the tube N will be forced downward within the tube E far enough to carry the holes 8 below the head of the hood F. From the collar a: there is an extension, 6', to clasp and slide on astationary straight guide, f projecting from one of the standards D.'

Preparatory to using the machine there is a thin woven cloth bonnet placed upon the frustum G, so as to cover it closely on its top and sides, such bonnet being to prevent the pulp fibers from getting into and choking the holes of the frustum. Surrounding the frustum at its lower part is a flat ring, h, beneath which headed rods z" project downward through the base H, through pockets or chambers k therein, there being within such pockets and to therods spiral springs Z, to draw the rods downward. At a proper distance from and underneath these rods are stops m, against which the heads of the rods bring up on the base H and frustum G being depressed to a proper distance for .removal of a pail-body from the said frustum. In the further descent of the said base and frustum the bonnet and pail-body will be upheld by the ring and loosened from the frustum, so as to enable them (the said bonnet and pail-body and said ring) to be readily lifted off the frustum.

The base H is provided with mechanism for locking it in its highest position. This mechanism (shown in under side view in Fig. 4) consists of two sectoral cams, n, inclined on their lower surfaces and pivoted to the lugs a. From each of them a shank, 0, extends, one of such shanks terminating in a handle, 1). Both shanks are connected by a rod, q, pivoted to them, so that on taking hold of the handle and moving it so as to turn its sectoral cam the other sectoral cam will be simultaneously and in like manner moved. These cams turn on andlofi the upper ends of the guides 12, and when turned on them, serve to effect the locking of the base. By .turning the cams 0E to enable the space within the hood and about the frustum G to be charged with the paperpulp. On a sufficient amount of the pulp having been introduced into the said space the tube N is to beraised, so as to stop the further flow of the pulp into the space. Next, the handle M is to be turned upward, and steam or air or water under pressure is to be let into the space surrounding the hood F, which may be done by means of a pipe, 1", provided with a stop-cock, s, and leading from aforce-pump or steam-boiler, such pipe opening into the stationary hood A, such hood having at its lower part a drainage-cock, a, and in its upper part an air-escape cook, '0 The pressure within the hood A will crowd the hood F upon the mass of pulp, so as to firmly condense it upon the bonnet and drive the surplus water through the frustum G. At the same time suction through the pipes e and i is to be produced, so-

Next, the base H is to be unlocked and is to be depressed sufficiently for withdrawing the foraminous frustum G and the made pail-body from the hood F, and to enable the pail-body to be removed, with the bonnet, from such frustum. After such may have been accomplished and the frustum bonneted, the said frustum and the base H are to be forced upward to their highest positions relatively to the hoodsF and A, and the base is to be locked.

I do not claim, broadly, the foraminous frustum, its supporting-base, the 'flexile or elastic hood, and the surrounding inelastic hood, arranged as described, such being common to various other machines for making pail-bodies or other like articles from paper-pulp.

1. The combination of the inelastic hood A,

'provided with the stuffing-box a, with the contractile hood F, encompassing the foraminous frustum G,-and provided with the upright pipe E, going through the said stuffing-box and furnished with the pulp-inductor N, arranged within the said pipe E, and having mechanism for operating it (the said inductor) for the discharge of pulp through and from it into the upper part or crown of the hood F, all being substantially as set forth.

2. The combination of the inelastic hood A, provided with the standards D and the stuffing-box at, extending upward from it, (the said hood,) as represented, with the contractile hood F, encompassin g the foraminous frustum G, and provided with the upright pipe E, going through the said stufling-box and furnished with the pulp-inductor N, arranged within the said pipe E, and having mechanism for operating it (the said inductor) for the discharge of pulp through and from it into the upper part or crown of the hood F, all being' substantially as set forth.

provided with the standards D and thestuffing-box :20, extending upward from it, (thesaid hood,) as represented, with the contractile hood F, encompassing the foraminous frustum G, and provided with the upright pipe E, going through the said stuffing-box, and having mechanism for raising it (the said pipe) and allowing it to descend, as specified, and with the pulp-inductor 'N, arranged Within the said pipe E, and having mechanism for operating it (the said'inductor) for the discharge of pulp through and from it into the upper part'or crown of the hood F, all being substantially as set forth.
