MACHINE FOR PRESSING THE BODIES OF PAPER PAILS.
SPECIFICATION forming part of Letters Patent No. 316,985, dated May 5,1885.
Application filed July 21, 1884.
To all whom it may concern (No model.)
The lower ends of the legs A are connected by Be it known that we, HENRY WV. LEONARD a three-armed bridge-tree, A, which is proand JOHN STEVENS, residing, respectively, at Syracuse, in the county of Onondaga, in the State of New York, and Port Byron, in the county of Cayuga and State of New York, have invented a new and useful Improvement in Machines for Pressing the Bodies of Paper Pails, of whichthe following is a specification. This invention relates more particularly to an improved machine for pressing the bodies of paper pails made of soft paper-pulp or halfstuff, for the purpose of compacting the material and removing the moisture so far as this can I 5 be accomplished bypressure. These bodies are formed by winding a web of soft paper stuff upon a suitable forming-mandrel, and the bodies so formed contain a large quantity of moisture, and would be weak and unfit to handle and liable to change their form, if handled and dried in this condition.
Our machineis designed to express the moisture and harden the material by a powerful pressure, thereby rendering the bodies comparatively dry and strong and enabling the bodies to withstand the handling in placing them in the drying-kiln, and to be dried therein without undergoing any change of form.
Our invention consists to that end of the 0 improvements in the construction of the machine whereby the machine is rendered effective and convenient in its operation, and which will be hereinafter fully set forth, and pointed out in the claims.
In the accompanying drawings, consisting of three sheets, Figure l is a side elevation of our improved machine. Fig. 2 is a horizontal section in line a: m, Fig. 1. Fig. 3 is a vertical section in liney Fig. 2. Fig. 4 is ahori- 4o zontal section in linez 2, Fig. 3. Fig. 5is' a vertical section, and Fig. 6 a front elevation, of one of the perforated pressing-sections. Fig. 7 is a top plan view of the form and pressingsections on an enlarged scale. Fig. 8 is aside elevation of the form.
Like letters of reference refer to like parts in the several figures.
A represents a circular horizontal plate, upon which the movable pressing-jaws are arranged, and which is supported by legs A.
vided at its middle with a step-bearing, a.
a is an upright shaft resting in the bearing a and journaled with its upper end in a bear- 5 5 ing, (i formed centrally on the lower side of the plate A.
B represents a bevel gear-wheel secured to the shaft a and meshing with a pinion, b, which is secured to the inner end of the horizontal driving-shaft b.
-0 represents three vertical screws arranged equidistant around the central shaft, a, and provided at their lower ends with steps, which turn in bearings 0, formed on the three arms of the bridge-tree A The upper ends of the screws 0 are journaled in bearings 0, formed on the under side of the plate A, and the screws are in this manner held against longitudinal movement while they are free to turn in their bearings,
D is a gear-wheel secured to the central shaft, a, and meshing with gear-wheels D on the several screw-shafts 0, whereby the latter are rotated from the central shaft.
E represents a movable frame through which the screws C extend, and which is provided. with screw-nuts 'e,in which the screws 0 work, so that by turning the screws in one or the other direction the frame E is raised or lowered.
F represents the conical form or core arranged centrally on the plate A.
G represents the pressing-jaws, and H the intermediate jaws or pressing-sections surrounding the form F.
I represents an annular horizontal plate arranged over the plate A, and supported thereon by strong upright posts i. The jaws G are arranged in radial lines with the posts t and slide in radial ways or guides t",formed on the plates A and I.
J represents connecting rods which pass through openings in the plate A, and are pivoted with their lower ends to the frameE and 9 with their upper ends to movable heads J,arranged between the posts 6 and jaws G.
j j represent toggle links or bars connecting the heads J with the posts t and jaws G, so that the jaws are moved toward the form 100 Fupon raising the frame E, rods J, and heads J, and from the form upon lowering said frame.
The jaws G are constructed with straight inner faces, 9, which converge upwardly in accordance with the upward taper of the form F and of the pail-body to be pressed thereon.
The intermediate jaws, H, are constructed with concave inner faces which approximately complete the circle around the form F. These concave faces are constructed of perforated metallic plates h, backed by concave horizontal ribs h, which are grooved vertically, so that the water which is expressed from the pulp can escape freely through the. perforations of the plates h and the open spaces behind the same.
The jaws H fit with their rear sides against the straight faces of the jaws G, and are provided on their backs with shanks h", which project outwardly between the jaws G and slide in radial ways it", formed on the plates A and I.
K represents curved springs secured to the rear sides of the jaws H and bearing against the rear sides of the jaws Gnvhereby the jaws H are held tightly against the faces of the jaws G and compelled to move backwardly with said jaws.
The form or core F is composed of a fixed upright central plate, f, cast on or secured to the plate A, and two movable curved segments, f, which can be raised and lowered on the fixed plate f. The latter extends diametrically through the core, and is provided at each end with two dovetail grooves,Z,converging upwardly, as clearly represented in Figs. 7 and 8.
The segmental portions f of the core F are provided at both ends with dovetail tenons or tongues Z, which slide in the grooves Z, so that by raising the segments f on the plate f the segments approach each other, thereby contracting the form. The outer surfaces of the platefand segmentsf are so formed as to correspond in their normal posit-ion with the interior tapering form of the pail-body to be pressed. The segments f rest upon pins m, which slide vertically in openings formed in the plate A, and which are secured to a crosshead, M. The latter slides on the vertical shaft a, and is raised by a lever, N, pivoted to a bifurcated bearing, a, secured to the under side of the plate A. The outer end of the lever N is depressed by a treadle, 0, thereby raising the cross-head M and segments f and contracting the form. Upon releasing the treadle, the segments f return to their former position by their own weighti The driving-shaft b is rotated alternately in opposite directions by belts p p or other suitable mechanism.
Upon turning the shaft 6 in the proper direction to lower the frame E the jaws G and H are moved outwardly away from the form F to the required distance to permit the wet body of the pail to be placed on the form.
This being done, the movement of the driving-shaft is reversed, so as to raise the frame E and force the jaws G and H, by means of the toggle-barsjj, with great force against the wet pail-body placed on the form F. The pressure of the jaws G and H compacts the material of which the pail-body is composed and forces the water through the perforations and channels of the intermediate jaws, H.
The screws are preferably provided with deflecting-plates 0, above the screw-nuts e, to protect the screws and nuts from the water.
Vhen the pressing operation is completed, the rotation of the shaft is reversed, thereby spreading the jaws Gand H and releasing the pressed pail-body. The segments f of the form F are now raised by depressing the treadle 0, whereby the form is contracted and the compacted pail-body liberated, so that it can be readily removed from the form. "When the pressed body has been removed, the segments f are lowered and the machine is ready for another pressing operation.
Our improved machine exerts a powerful pressure upon the wet pailbodies, whereby the water is quickly pressed out and the pulp so compacted that the bodies can be conveniently and safely handled, and it performs the operation of pressing the bodies in a very simple, expeditious, and convenient manner.
