FERDINAND PHILIPPE EDOUARD CARRE, OF ST. PIERRE LESl NEMOURS,

ASSIGNOR OF PART INTEREST TO JEAN B. J. MIGNON AND HENRI S.

ROUART, 0F PARIS, FRANCE.

lNlPROVEMENT IN lCE-MACHINES.

Specillcntion for Be it known that FERDINAND PHILIPPE EDOUARD CARRE, of St. Pierre les N emours, (Seine-et-Marne,) France, did invent a certain new and Improved Apparatusfor the Artificial Production of Ice and Gold; and that the following is a full, clear, and exa-ct description of the same, reference being had to the annexed in which- Figure 1 is a vertical cross-section of the apparatus; Fig. 2, a similar view of a freezinghamber, which may be substituted for D of The invention consists of an apparatus for the practical production of ice and cold and is formed of two chambers or recipients, connected by a pipe or pipesone chamber to contain an absorbent capable of holding a volatile gas, the other being a liquefyingchamber into which the gas is driven to be condensed or liquefied. The chamber containing t-he absorbent is heated to drive olf the gas from the absorbent, which gas is conducted through a pipe or pipes to the other chamber, where it is condensed and liqueed by its own pressure, and by having beenproperly cooled, then suddenly'again volatilized, producing great cold and reabsorbed by the absorbent, which has been suitably cooled, in the rst chamber, from which it is to be again driven forth.

To enable others skinea in the art to mko.

and use the invention, its construction and operation` are described as follows:

A, Fig.. 1, is the recipient containing the absorbent. B are disks filling up the interior,

each having an opening with liange, C, in'the middle. D is the recipient into which the gases or vapors l'low to be liquefied. E is a. connecting-pipe. F are disks, each in the shape of the convex surface of the frustum of a cone, each fastened all around the lower edge to the inside of, the recipientD, having openings in the middle, thus forming shelves drawing making part hereof, iciently to drive olf the gas, but not enough vrof Letters Patent No. 30,201, dated October 2, 1860; reissuoNo. 5,287, dated February 18, 1873:

DIVISION A. o on the inside of the recipient D. G, Fig. 2, is,

an inner chamber, surrounded with an annular chamber, H, the latter connecting with Pipe E,fwhen the recipient, Fig. 2, is substitutedfor recipient D, Fig. 1.

The absorbent, for which is in recipient A, on disks B, kept in place by flanges C. This absorbent contains gas-ammonia preferred. Recipient A is heated sufto vaporize the absorbent itself; and this operation is facilitated by the number of shelves or disks B containing the absorbent, thsallowing it to be easily and quickly heated. The gas, after separating from the absorbent, passes through the pipe E into the liquefyingchamber or recipient D, where, 'in consequence of the pressure of the incoming gas, and assisted by the water surrounding the recipient, which extracts from the gas its latent heat, it becomes liquefied and falls on shelves F. The heating of the recipient A is then stopped, th'us relieving the pressure on the liqnetled gas. The Water which has' been used to assist in the liqnefaction of the gas is then removed. This, coupled with the relief of the pressure, induces the volatilization of the liqueled gas. This volatilized gas 'now extracts the heat from whatever liquid surrounds recipient D, or is in chamber G, and freezes it. Fig. 2 may be substituted for D,

. Fig. 1. The gas is liquelied'and volatilized in chamber H, freezing whatever is contained in G. When the heating of recipient A is stopped,

.a partial or relative vacuum is formed in the space between the absorbent and the liquefled gas, assisting in the volatilization of the latter.

The disks F,if desired, may be dispensed with, as the operation can be carried' on without them. v A

It' desired, a stop-cock may be employed in connection with pipe or tube E, to stop the operation at the will of the operator.

Havig thus described the inventioo, what is claimed as'new, and desired tobe secured by Letters Patent, is

1. An apparatus for tho tionof icc and cold, consisting of .two chambers. one for separating the gas from the ab.

sorbent containing iti, :md the otherfor condensing it, connected 'by a tube, E, or its equivalent, substantially as described.

2. l-i-'an apparatus for the practical production of ice and cold, chamber A, having" practical produc` vinternjall disks B and lilnges C, substantially as described.
