MACHINE lFOR PORMING HOLLOW WARE FROM WOOD'PULIE. No. 287.61m Patented oct. so, 1883K JOsEPH e. Bonenor WATERVILLE, finiture.
MACl-HNE FOR FORMING HOLLOW WARE FROM woon PULP.'`
SPEGFIATION formnervartuof .Letteralatent .No.,;28?;614,. dated lOctober. 30,1883. y Application inea Aprilalsea; No man.)
Be it known that I,y .Iosnrrr G. Bones, a citizen of the United States, residing at Vaterville, in the county of Kennebee and State of Maine, have invented certainmew and useful Improvements in Machines for Forming 4 Hollow Ware from Wood Pulp, of which' the following is a specification, reference being had therein to the accompanying drawings.
My invention relates to machines for formi ing pails yand other` hollow ware from wood f pulp-or other paper-stock.
Heretofore devices and processes have been `employed in making paper pails, buckets,and
the like articles, wherein the means or parts have been so arranged that the pressure could be applied on the articles from. the inside outwardly; but the result has not proved a suceess lhis .hasl arisen chie-ilyY from, the Afact that thelpeculiar manner of applying the press ure served to separate the ber or material f .f which the articles were made, and. thus seriously damaged their unity, and they were often cracked. There has alsobeen used for this general" purpose a niold in two parts working toward each other and thus pressing the material between them; but such a device is somewhat complex in structure, and not well adapted tothe uses had in View in the present invention.
The object 'of my invention is to form apail` or similar article of paper-pulp, so that the fiber shall be laid in a strong and uniform manner, and a heavy pressure may at once be applied in a direction at right angles to all parts of the surface without disturbing the arrangement of the fiber or the form of the pail.
I accomplish this result by means of mechanism shown in the accompanying drawings, of
and a, opens` into the cylinder A. Within.
the ring Il, and extending entirelyaround it, is the circular chamber b, i'iom,`which lead small holes or perforati-Ons, b', (see Fig. 2,)
which open within the cylinder A. The pipe B', with its valve B2, connects with the chamber b.
C, which I iind to work, but when molded in the exact formof the Outside of the pail after the latter has been compressed.
D shows a pail after being formed.
F is a perforated forni covered with a felt or other porous drainer, E, the outside of which will be the exact shape and size of the inside ofthe pail to be formed. The bag C,
before lthe pail is formed, fits more or less closely over the ldrainer E, The lower edge of the former F contains a iiange, on which confines the drainer E to the' former F. This packingring G` also forms a tight joint between. the ,former F and. the ring. .Bl The former F is bolted, by means of the ring H, to
in the frame J, by* means o f the sweep K or other devices. A
Having described the construction yof my machine,`I now proceed to show its manner of operation. i
The valves a and a3 being closed,the pulp is admitted under considerable pressure, through the pipe B, the chamber b, and the perforations b', tothe space between the bag C and gins at once to pass through the drainer E and the perforated former F on all sides., leaving the pulp deposited on the ysurface of the felt. The pulp,`being forced in' much faster E, fills they space between the bag C and the drainer, and expandsthe bagC until itlls 4the insidey of the cylinder A, as shown by dotted lines. A When enough pulp has been passed into the' cylinder to' form the pail of sufficient thickness, the valve b2 isclosed, shutting oif the supply.` llhe'tensio'n of the rubber bag C, which has been distended until now, causes it to contract toits molded form, which should always be somewhat smaller than the outside of the formed article. As thebag C contracts it forces the water of the pulp which it incloses through the drainer and closes Vitself tightly around the outside of the formed l Clamped between the ring B andthe cy1in Jder A is the flexible rubber bag or diaphragm`A 'rests the rubber packing-ring G,fand which the' frame I, which is rmovable vup and down ,y
the drainer E. The water of the pulpv bethan it is able to escape through the-drainer IOOl ail as shown in Fi 1. The valve a is now P 7 p opened and water is admitted through the. pipe a, and the space between the rubber bag C and the inside of the cylinder being lled, a heavy pressure is applied. This hydraulic pressure', .acting at right angles to the surface of the bag C at all points, compresses and consolidates the pulp, ,andjdoes not impair its strength by changing its iib'rous structure. The pail being formed, the frame I,bearing the former and the formed pail, islowered, as shown by dotted lines', Fig. 1, and the pail removed. The pail, having received a pressure of one hundred pounds to the inch, for instance, which I have found suii'cient, has nearly all the water extracted, and may be caleudered or-oth erwise nished withI ease.
The water used for pressure is drawn off by as; or a special waste-pipe means of the valve may be used. v
lIt will be observed that by my process the pail is formed and compressed to any desired f extent automatically and without, handling the y ware or taking the machine apart.
I amaware that hollow ware has been formed inside of Va mold and hydrauli c` pressure applied by means'of a removable rubberl bag; but when a heavy pressure is thus applied it. has' been found .that the sides tend to break away' from the bottom, and thus materially weaken the corners. By my process the corners. are' strongas any porsharp and compact and as tion-,0f the pail.
Thexact size and shape of the bag C is a v matter-t0 b'e determined by experiment in each case.,` y u v l y v l I donot'wish to coniine myself to the de,-l vvicehere .shown for. raising and lowering former F, for this ,may be done in" variety of v ways and is no part'. of my invention.
. The pulp maybe admitted between the' bag C and the felt E by 4other means than here shown; but-I consider this the preferable way.' The former F, with its felt jacket E, may be replaced by a ,strong woven-wire former covcombined with the removable former F, with its draincr E, substantially pose set forth.
2; In a machine for forming articles of paper-pulp, the cylinder containing rubber diaphragm C, combined with the porous former F, the pipe B,for admitting the stock between the diaphragm and the former, and pipe a, for applying hydraulic pressure, all substantially as described and shown. p
3. A machine for forming hollow ware. of
as and for the purpulp, consistingof a porous former, thel outside of which is covered with a closely-fitting rubber bag, between which and the former the pulp is admitted, combined with a pump or other means of applying hydraulic pressure,
substantiallyas shown and described.
4. The' process of forming vhollowware of pulp on the outside of a porous former by forcing the pulp between said former and a rubber bag litting over it, and afterward applying hydraulic pressure on the rubbelgall in one operation'and without removing the formed article from the machine, substantially as shown and described.
5.'y The process of forming hollow articles of pulp', consisting of forming the articles on the Aoutside of a porousformen'and then apply-ing hydraulic pressure by means of a rubber'bag fitting over `the article, substantially v,as described and set forth. f .l
In testimony whereof I aiix'my signature in presence of two witnesses.
