Abstract: 22,449. Schneider, W. E. Oct. 18. Moulding pulp.-A machine for moulding boxes, casks, or barrels, and galvanic battery cells from papier mÔchÚ or other pulp is shown in front elevation in Fig. 1, and in sectional plan in Fig. 6. Fig. 7 is an elevation of the mandrel, around which the box is compressed by the action of perforated formers 4, Figs. 1 and 6, faced with wire netting, and of a top plunger 6<x>. This mandrel consists of corner pieces 17<a> ... 17<d> united by wedge-shaped pieces 17<e> . . . 17<h>. Plates 17<x> (only four of which are shown), fixed to the corner pieces, take into grooves in the wedges, so that, when the latter are drawn downwards, the mandrel contracts, while retaining its rectangular section, so as to facilitate the withdrawal of the finished box. The corner pieces 17<a> &c. are supported by angle-pieces 1<c> at the corners of an open-ended box 1<b> depending from the base-plate 1, and carry long pins which pass through horizontal slots i<d> in the box, and the wedges 17<e> &c. are attached by pin-and-slot connections to a movable plate 12. The base-plate 1 is surrounded by a trough 1<a>, and supports vertical angle-pieces 2, to which is attached a frame 9. Pivoted to this frame are arms 8, acted on by springs 8<c>, and having shoulders on which a frame 8<e> rests. Catches 8<x> are pivoted to lugs on the underside of the frame 8<e>, and are normally pressed against it by stirrup-like springs 8<aa>. To arms forming part of these catches are attached rods 8<a>, provided with pins or keys 8<xx> at their lower ends. Depending from each side of the frame 8<e> is a pair of bars 15 united by a crosspiece 15<x> and by pins 16, which project through vertical slots 3 in the angle-pieces 2 and through slots 4<c> in the formers 4, the latter slots being partly vertical and partly inclined. The lowering of the frame 8<e> thus causes the pressing inwards of the formers 4. The operating-link 5 is pivoted between plates 6, attached to a plate 6<a>, and having bevel-ended arms 7, which in their descent push outwards the arms 8. At the same time, the plate 6<a> is forced past the catches 8<x> into the frame 8<e>, with which it then descends. In the return motion, the pins 8<xx> are caught by stop bars 8<b> through which the rods 8<a> pass, and the catches 8<x> are thus withdrawn from the plate 6<a>. To the frame 6<a> are attached four rods 11, the lower ends of which carry a plate 18<a>. Two pairs of L-shaped spring fingers 18<x> attached to the plate 18<a> embrace bars 18 pivoted to the base-plate 1, and having notches adapted to support the plate 12 in its raised position against the action of springs 12<ab>. Springs 18<aa> normally press the bars 18 inwards, but the fingers 18<x> act upon curved plates 18<ab> on the bars at the commencement of the up-stroke, thus releasing the plate 12 and causing the mandrel to contract. At the same time, the plate 18<a> catches projections 13<a> on bars 13 passing through it, raising these bars and with them a perforated plate (not shown) which fits on the top of the mandrel. and is suitably shaped for moulding the bottom of the box. This plate lifts the finished box, and, as the plate 18<a> is ascending, an arm 21 attached to it acts upon a lever 22, which by means of a pin 22<a> presses inwards. an arm 22<b> and a box-carrier of suitable shape to pass under the edges of the box. When the bars 13 have risen sufficiently far, the projections 13<a> strike the edges of the apertures in the plate 12 through which they pass, and are pressed towards each other against the action of a spring 13<x>. The bars 13 and the plate they carry are thus released, and fall into position for the next operation of the machine. The pulp is fed by hand into the space between the formers 4 and mandrel 17, and in the movement of the formers 4 some of it is forced out over the plate which covers the mandrel before the plunger 6<x> has descended upon it. The plunger may be perforated to allow of the escape of water upwards, and, to improve the corners of the box, wedgeshaped bars 4<d>, Fig. 6, may be keyed to the plate 12 so as to slide downwards and outwards when the mandrel is contracted. Cells for storage batteries are made with ridges on the bottom to support the plates.
