@ mwwly;



SPECIFICATION forming part of Letters Patent No. 228,542, dated June 8, 1880.

Application filed March J, 1880.

To all whom it may concern:

EDWIN LISTER, (the firm of LISTER BROTH- ERs,) both of the cityof Newark, in the county of Essex and State of New Jersey, have in vented certain new and useful Improvements in Apparatus for Eva jiorating Liquors for the Manufacture of Glue and other Purposes 5 and we do hereby declare the following to-be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to the evaporation of liquid in the manufacture of glue, and has for its object the production of a brighter and 0therwise better quality of glue in less time than has been heretofore accomplished; and it consists in an apparatus comprising acasing,within which is arranged a group or coil of pipes, beneath which is an inclined table, and under that a receiving-vat, so that when the liquid is introduced into the apparatus and spread, by means of a perforated plate or trough at the top of the casin g, it will run or flow around and between the pipes, pursuing, as it were, a rippling course, and thence onto an inclined table, over which it will pass in a thin sheet into a vat below, from whence it may be elevated to the top of the apparatus, and caused to again. pursue the course as at first, and as often as may be found necessary to reduce the liquid to the proper consistency for its formation into sheets of glue.

It differs from other apparatus in causing the liquid to travel downward, as described, in athin rippling stream and at an inclination from a perpendicular line, whereby the liquid is compelled to move more slowly and expose a greater evaporatingsurface than where it passes over a smooth inclined surface, even though several of these inclined surfaces be arranged so that the liquid will flow first in one direction and then in an opposite direction.

The accompanying drawing, which illustrates the nature of the invention, represents a section of the mechanism employed in carrying out the process, in which-- (Model) A is the vat or reservoir containing the liquor to be reduced, which is connected, by the pipe (1, with a steam-pump or other means for drawing the liquor from said vat A and forcing it through a pipe, it, also connected with said pump, into a trough, B, located ten orfifteen feet above the vat A.

Across the top of said vat A are arranged supporting-beams b, which are connected to gether by and support a slightly-inclined table, 0, which is made usually of copper, and upon which the liquid falls, and slowly, in a thin sheet, runs off into the vat A. Upon each su 'iporting-beam b is erected a series or stack of metallic steam-boxes (I, said boxes resting one above the other, and so arranged that they may, when necessary, be easily repaired. These boxes are connected each with the one opposite by a nest or group of pipes, c, in the manner indicated in the drawing, which allows free passage of steam or heated air from one box to the other, the boxes cl being supplied with steam or heated air from any generator by means of the tubing g and g, connected to said boxes, the exhaust-steam finding egress through the tubes h and h on the opposite sides.

Above the horizontal tubes 0, for evaporating the liquor, is placed the trough or troughs B, above referred to, the bottom of which is perforated at i, so that the liquor, asit is emptied into the trough, spreads over the whole bottom thereof, and passes, not too profusely, through said perforations i, and falls directly upon the said horizontal metallic tubes 0 throughout their entire length. This trough B is supplied with liquor from the vat or reservoir A by means of a steam-pump, or by any other appropriate means for forcing or raising liquids, and thence through the pipe is, as already stated.

The evaporating mechanism is all inelosed, or nearly so, by the walls 0, which prevent the access of cold air, and also prevent the steam from passing out through the building in which the apparatus may be placed. Through the roof of said building is a chimney or flue, D, located immediately over the trough B, to allow the steam or vapor arising from the liquor to pass off into the outer air.

In operating our invention the desired quantity of prepared liquor is poured into the vat or reservoir A. The steam-pump is then put in operation, and draws it through the tube a, and forces it up through the tube is into the trough B, from whence it flows through the perforations i in the bottom of said trough B evenly, but, as already stated, not too profusely, over and through the several nests of heated horizontal metallic tubes 0, pursuing an irregular course around and between the pipes, and then down upon the inclined table or dash-board 0, from whenceit flows in a thin sheet at an inclination from a perpendicular line, and, by reason thereof, slowly down into the vat or reservoirA, this process being continued until the liquor is reduced to the requiredconsistency, when it is run otf into coolers, which are allowed to stand, in the usual manner, until the liquor has hardened into a solid jelly prepared to be cut into slices for drying.

The table a is heated by means of the heatradiating tubes 0, and, further, by the heat thrown off from the heated liquid in the vat beneath the table.

Having thus described our invention. what we claim, and desire to have secured by Letters Patent, is-

1. The combination of perforated trough B,

heat-radiating tubes 0, inclined table 0, and vat A, the several parts being relatively arranged to operate as described.

2. An apparatus for evaporating liquor in the manufacture of glue, consisting of a chamber, 0, provided with escape-flue D, a series of groups of heat-radiating pipes arranged within said chamber, each group being provided with separate and separable heads for the admission of steam, and also with separate inlet and exit pipes q q and b I), a de fleeting-table beneath said radiating pipes, and a recei ing-vat beneath said table, substa-ntially as set forth.

3. The chamber 0, provided with escapetlue D, a perforated distributing-trough, B, located in the upper part of said chamber, a vat, A, in the lower part, a deflecting-table, 0, between said vat and trough, and means for heating said table, substantially as and for the purpose set forth.

In testimony that we claim the foregoing we have hereunto set our hands this 24th day of February, 1880.
