sPncIFIcArIon ror part r Letters Patent-No. 513,017, dated January 1c, 71894. Application filed February 18, 1889. Serial no. 300.343. (No model.)
To 00% whom it may concern:
Be it known that I, FRANK BENONA How- ARD, a citizen ofthe United States of America, residing at the city of Montreal, in the district of Montreal and. Province of Quebec, Canada, have invented new and useful Improvements in Machines for' Compressing Pulp; and I do hereby declare that the following is a full, clear, and exact description of the same. 7 C
My invention relates to improvements in the apparatus by which pulp is pressed into shape for the purpose of forming it into slabs or masses having regular or irregular embossed surface or surfaces; and the object of my invention is to form a pattern or die plate in such a manner that the highest of the embossments formed by it will be equal to the thickness of the pattern or die plate and thus form openings through it and thus give a better drainage at these points, while for additional drainage at the lesser heights of embossments perforations in the pattern or die plate will be formedand these will be covered with wire cloth or perviousmaterial.
In the accompanying drawings similar letters and figures of reference indicate lik parts. v
Figure 1, is a side elevation of portions of a press with mold or former arranged in connection therewith. Fig. 2, is a central longitudinal vertical section of the mold or former shown in Fig. 1, taken at about theline 41:, Fig. 4, with section of the pattern or die plate 0, shown in connection therewith such section of the pattern or die plate being taken at the line at, Fig. 3. Fig. 3, is a plan view of a modification of the pattern or die plate 0. Fig. 4, is a plan of the upper side of the upper portion f, of the mold or former detached. Fig. 5, is a plan of the lower portion h,of.the mold or former placed upon the perforated bed g, also showing pattern or die plates (two) O in place within it and occupying a portion thereof. In the remaining portion of the mold or former, portions of the various parts underlying the plate a, of the pattern or die plate 0, are shown in plan View. Fig. 6, is a plan of the under side of a portion of the casing 2', showing an inverted plan View of the projections Zr. Fig. 7, is a section of a portion of the drainer-bed n, taken at line 00, Fig. 5. Fig. 8, is a longitudinal section of a portion of a pattern or die plate for forming embossments at various heights; showing also the manner-of forming drainage to the same, also showing the pulp a, as having been compressed therein; this sect-ion is taken at the line m, Fig. 9. Fig. 9, is a plan of the portion of the pattern or die plate shown in section in Fig. 8. Fig. 10, is a section taken at about line 00, Fig. 4., similar to the section shown in Fig. 2,'but in this case arranged with pattern or die plate or plates placed in the upper portion f, of the mold or former as well as in the lower .portion h, so that embossed surfaces will be formed on both sides of the compressed pulp.
d, is the head of a press, in this case stationary, and e,.is the platen of the press which is arranged to move up and down. If desired a vice versa arrangement of the two may be made.
To the head (Z, of the press is attached by bolts and nuts (F, the upper part f, of the mold or former. This as shown consists (see Figs. 1, 2, 4 and 6,) of a casing i, having conical projections Zn, on its under side. Each side'of the casing *Z, is provided with 2. marginal edge or strip M, which may either be made integral with the casing 2', or attached thereto as desired. Theseare provided with bevel edges a 'r, is a chamber formed in the casing Z.
s, is a pipe connected with the chamber '1", and with any suitable air-pump or other ordinary means attached to it, by which a vacuum may be formed in the space 15, about the" projections Z0, and in the chamber 0".
' Z, is a perforated plate placed close up, under the projections k, and may be held in place by being fitted tightly within the marginal edges a or with solder, or in any ordi-' nary manner.
1%, is a wire cloth filter or pervious surface 9 placed under the plate Z, and attached thereto pulp is pressed in i the former or mold or when there i is a vacuum in the space t, or both.
On the platen e, is placed a drainer bed n. (See Figs. 2, 5. and 7.) This is provided with ribs o, and at one or both ends of the ribs, with a channel 19, provided w-ith' oneiorwmore discharge pipes q. v
g, is a perforated plate laid upon the ribs 0, and upon this is laid the lower part h, of the mold or former. This is arranged to fit closely to the upper part f.
u, isa filter wirecloth forming a pervlous surface placed within the lower 1ptlllIh,"-Of the mold or former and upon this are placed the pattern or die plates 0, which may be an ranged with regard to size so that the loweri partlh, of the former or mold will hold oneor more ofthem as desired.
jl'lhe pattern or die plates 0, eachconsists of a'die. plate a, an exact matrix of the pattern? on-embossments to be formed on theinassof pulp pressed; it is in thickness equal'towthe height of tthe highest relief or embossments formed on the pulp, so that in the. places in which these occuropenings areformed com pletely through the plate a; the bottoms of these openings being formed by afine filter wirelcloth b,and perforated. plate 0 which aremade (in plan)the same. size as the plate a',.an'd.attached thereto bysoldering at the edges-or in any ordinarymanner. i
.Ther late a, is provided with beveled edges a These areset out with asuitable calking toolagainst the walls of the lower part h, of the mold or former and against the sides of; eachflother, when more than one pattern or die plate 0, are placed together in the lowen parth,=of the mold or former. This is done to prevent the pulp from escaping-at. these; places.
TShouldit be desired to form em-bossments on both sides of the-compressed pulp, the=ap paratus will beiarranged as showninFig. 10, which is thesameas Fig. 2, onlythat in this casethe marginal edges a aremadeof greater depth-or width, sufficiently so, that a pattern or die plate (or plates) similar to those in the lower part h, may. be placed in theupper part 7, also under the perforated plate Z, and filter wire cloth or pervious surface m.
Whenever the pattern or letters,&c., to be formed on the pulp, are such that a central or detached 9 portion (1, of the plate (1., (see Figs. S and 9)'will be required torbe formed; orias in the letters P, in theword pulp, (in Fig.3) such portion will be attached on the wire cloth .or; pervious surface I), by solder or in any other desired manner, and thus held in the proper relative position with regard to the other parts of the letter or pattern.
-When the pattern or embossments to be formed on i the pulp aresuch that several heightsof relief are requiredyas shown at 1,
2, and 3, in Fig. 8, only the highest asat 1, wiillform openings in the pla'te a.
To prevent water from the pulp lodging in the recesses formed by the various heights of relief as at 2, and 3, the portion 6, of the plate a, is provided with perforations Z. The perforations"atitheheight of relief 2, are not absolutely necessary but I prefer to provide them to give .greater freedom of drainage. The perforations at the heights of 3, are necessary because by the relative position and heights of the relief at 2,. and 3 a recess is formed. "The-various heights of relief uwillbe covered asxshown with wire f, forming pervious surfaces at such places.
From the above it-wilL be seenthat-fwhen or embossments; they plate a, .is made solid throughout except "where the openings are caused'bfor the said embossmentsgiand that the wire, cloth I), must necessarily be present The perforated ;plate .0, it forms. ta clamp to clampthe wire cloth I) between [it and the; plate a and -to-protect it from dis- 1 placement byiany. strain to which :it-mightlbe 9 5 i subjected when: the pattern :or die; plates are i being. placed, adjusted 1 and. secured int the l mold or former. Also that'whereasa thewperifOFEttlOllS in the drainer plate g; are large, land a if. the .wirecloth b, weretlaidt immediately ;upon it the .force with -whiclnthe pulp 'llS ;pressed would cause the -wire 010thwt0$3 into them. To prevent this tthexth-in finely perforated plate c,is.also used. .Again. .tto prevent-any obstruction of the drainage by areasonrof the perforations intthe perforated plate a, not agreeingwwith the perforation in the drainer plate or bed g, the coarse wire cloth this interposed betweenthem.
Whatl claim isas follows:
1 1.. In: a machine for moldingpulp. articles with embossed surfaces, thevcombination *ofia mold or formeryhavinga. perviouswsurface; land a pattern ordie plate fitted to and supported on said mold or formerysaid pattern plate having openspaces oorrespondingwi-th the raised portionsof thetdesignsubstantially as described.
