IMPROVEMENT IN DEVICES FOR FREEZING FISH-9 NIEATS, &c.

The Schedule referred to in these Letters Patent and making part of the sarn.'

To whom it may conce/rm,-

Be it known that I, DANIEL Y. HOWELL, of Toledo, in the county of Lucas and State of Ohio, have invented a new and usef'nliIinprov'ement in a Box for Freezing l1`ish,.IlIeats, ALegend I do declare that ythe following is altrne and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon, and being a part of this specication, in whch- Figure l is a perspective view of my improvement; Y

Figure 2 is a longitudinal vvertical section' of thc- Figure 3 is a cross-section of the bottom and lower Like letters indicate like' partsin each ligure.

The nature of this invention relatesto an apparatus for freezing fish, meats, game, Sec., for preservation and It consists in the arrangement, within a peculiarly-"-r constructed box, of certain blocksaud pairs of metal sheets, in such a manner-=thatcells of various' sizes the freezing being effected by filling thespaces be:` tween the cell-walls with brokenice and salt, or other by the thin plates to the articles in contact with their other sides; also, in the employment of clamps for forming a closed cell, to pi" Ventthe entrance of the re'rig'erating-mixturc in iifling the box` with it, the wholebeingarranged to' operate in the manner more fully hereinafter set forth. h

In the drawing- A represents the front ahd back walls and bottom of a box, connected by a transverse partition, a, which divides it into two compaitln'ents, having their ends hinged to open4 outward, as shown, the whole being covered with a suitable lid, A.

In the bottom of the box', a ser'es of grooves converge at drip-openings b, to carry o" thewater from the melting of the ice;-

-B arerectangular plates, of any suitable non-corrosive-sheet metal, with which thecells areformed in the following manner Y Next to the transverse partition,` I stand on end, at thefront andback of the box, a block of `wood, C, against the edge of which I stand one ofthe plates B. I then lay across the bottom of the box, in contact with the said plate, the botten; block D, grooved on the under side, to permit'the water to ow under it, and whose width is'that ot' the proposed'cell. Then', on the endsof the block D,I stand the pointed or I v pose set forth.

.receive articles of varioussizcs, by having sets of arched blocks ot` the various widths required. In like manner,.the number ot' cells in a box and the distance between them may be varied by employing partingblocks of different widths.

To freeze a quantity ot' sh, for instance, they are .placed in the open cells, head downward, as is inost convenient. When each cell is full, the top edges of the sheets are brought together and held in that posi tion hy the clamps I1", which are slipped over them,

as shown in g. l and the left halfof iig. 2. lIhe spaces ybetween the c' lls are then filled with broken ice and salt, or other. suitable freezing-mixture, and

the coverV shut dowx'.- rIhe intense cold produced strikes through the t iin sheet metal to the'sh in contact with'it, .and sieedily freezes them. The water from the inciting ofthe ice :Hows in the grooves to the drip-outlets and' liasses ont, the bottom pieces of the cells keeping theishdry, which, it' wet, would. freeze 'very slowly, or not at all.

When the box is to be emptied, the cover is raised, and vthe ends of' the compartments opened, when their contents `may be readily removed. A

The principal objectl have in the use of the'` clamps is ,to'close the cells against the entrance of the mixture to their contents. .Ihey are not, therefore, essen tialto the freezing process, as the cells may bel left open, care heilig taken in charging in the freezing mix- -ture -to guard against its introduction therein; or the cells may be closed with slats for covers. v

Where the articles to be frozen are of uniform size, permanent blocks and strips may he secured to the walls ot the box, the plates heilig made to slide down to place between them."

What I claim as my lrinvention, and desire to secure by Letters Patent, is-7 v l. The employment of sheets of'metal, arranged in pairs in a suit-able hox,iin connection with a free-zingmiXt-ure, substantially as described, and for the pur- 2. The arrangement. within the box A, of the sheetmetal plates, B and rblolts (l, D, and E, substantially- \Vitnesses:
