Letters Patent No. 108,879, dated November 1, 1870.
IMPROVEMENT IN STEREOTVPING.
The Schedule referred to iix. these Letters Patent and makingv parl: ci the same.
I, ALONZO CHACE, of Ithaca,Tompkins county-I and State otlrNew York, havel invented an Improved Method of Drying'Stereotype-Matrices,'together with certain devices for effectingl the same, of 'which the following is a specification. r
This invention relates to the drying of stereotype matrices in a vacuum, and tothe combination of a vacuum-chamber, and accompanyiu g chambers,l abovel and-below it, so arranged as to provide a vacuum, heat, and condensation of vapor, for the. purpose ot' drying the said matrices at a minimum expenditure of time, temperature, and power as nearly asmay be. -It is especially adapted .to the rapid-and economical drying of papier-mache stereotype-matrices at a temperature which will notinj ure the type.
The following is a description of the accompanying drawing:
Figure l is a side elevation. oi'a machine or appaatus devised for the purpose of applying my inven- FigureZ is an elevation, showing that endof the apparatus -which is toward the right han'din iig. 1.'
Figure 3 is a Vertical transverse section through the4 vlineJ J in ig.1.
Figure 4 is a plan.- .v l Figure 5 is a horizontal longitudinal section through the line L Lv in iig. 2.
Figure 6-is a'horizontal longitudinal section through the line K K in g. 2.
Figure 7 is a fraction' of "the same section show'n in' :fig-3, enlarged, with a form of type, matrix, &c., in
the position which they occupy while drying.
W W, igs. l, 2,andA 3, .represent a wooden frame, upon which the apparatus rests.
F F,'figs. l, 2, 3, 4, 5, 6, and 7, is an iron screwframe, through the upper part .of which passes the screw-S, gs. 1,2, 3, and 4. y f
The lower part ofthe screw S is fastened to the platen C C, in such a manner as to allow the said screwto turn without becoming detached.
By tui'ningthe lever R, figs. 1,' 2, and 4, the screw `S, and with itv the platen 0 C., .is raised and lowered,
4as shown by the dotted lines, lig. I'.
This frame F, fig..1, has upon its under sideA the projecting pieces vL L, by means. of which it is fastened to the bed D D, v
D D is a hollow. bed or box', figs. 1, 2, 3, 6,`and 7,
containing the air or steam-tight chamber e e c e e e,
divided into as manyapartments as letters by the partitions t' 'i i, figs. 3, 6, and 7.
AFig; 6 shows,i|1 section, a plan Vof this chamber,
which is furnished with an ingress-pipe, I, and an egress-pipe, I', through which steam, hot or cold water may be made to iiow in the :direction of the arrows, thus' heating or cooling the chamber, and, by
ilskmeans, the contents of the vacuums-chamber V, asv
may be desi-red. Anyliquid or gasniay be employed 'to heat o'r cool vthis chamber. 'lhebed D D is of iron-` I C Ois a platen, 4fi gs. 1, 2, 3, 4, 5, and 7, provided witl the strengthening-bracesB B B B B B, iig. 4.
This platen (l O is` of iron, and contains the cham-A ber e' e c eee,.iigs. 3 and 7, which, in all respects of nish the vacuumfchamber V and its conten'ts with heat or cold, as will be found desirable in the process of drying, these chambers C -G-andfl) D being cons nected with reservoirs of hot and cold liquid or gas,
which reservoirs, forming no partv of" my invention,A are'not shown. The best result will be obtained by using one oi' these chambers for heatingthe contents of the vacuum-chamber V, and the other for condensing.
the vapors given4 oii', upon the cold wall which forms a partition between it and thc said. vacuum-cham'berV.
It is immaterial which of these chambers is employed as 'a heatingand which as acooling-chamber, and` Aeither may be used alo1ic,-tl1ough, ot` course, with less eicct. l
u Two objects are attained by applying heat to the contents of the vacuum-'chamber V: `rst, more rapid v evaporation; second, the preventing the matrix from freezing, as would otherwise occur from absorption of heat during `thernpid evolution of yapor.. Gooling the surf-'ace of one'side of the vacuum-chamber V vwould tend to cool the whole chamber, and so retard the'cvaporation but for the counteracting inflence ot' the heat'proceeding from the other surface. As itis, with proper experience, thc cold wall maybe made to condense the' vapors ot' the vacuum, and thus relieve it of their tension, without checking the process of drying, but, on the contrary, greatly 'assisting it.'
The vacuum-chamber V,'iigs. 3, 5, and 7, is formed by screwing the platen C G down upon the bed D D, figs. 3'and7. The platen C -C has arecess formed by the rim d, which, brought down upon` the bed D D, incloscs the space V. Air-tight contact between d and D is secured by placing the packing' f between them, and the space V, v
thus'iuc'losech becomes the vacuum-chamber.

The layer of eloth or paper retains any moisture condensed upon the louter surface ot the platenU C, which is thus prevented fromdromiing back upon the matrix a' :c fr
From the Yaeuuiii-chamber V the air is exhausted (by any of the well-known methods of' obtainillg a vacuum) through the pipe H, figs. 1, 2. and 5.
The screw S, the screw-frame F, and aplain platen, containing no chamber of any kind, but used to keep the mat'rixfin its place while drying, are used now in drying papier-mache stereotype-inatrices. A steam bed or box is also used for the same purpose, upon which the type (with matrix and blankets upon it) is heated by steam to a degree/of temperature not far from its melting-point. This 'expels the moisture from the matrices, but gradually injures the type by causing them to lengthen unequally.
