SPEIFIGATION form'ing part of Letters Patent No. 224,383, dated February 10, 1880.
' Application filed December 10, 1879.
To all whom 'it may concern:
Be it known that l, HANS BRGGEN, ot' the and State of New York, have invented an Improved Ice-BX, of which the following is a specification.
My invention relates to improvements in iceboxes for the reception and cooling of barreled beer and ale, and for other similar purposes which necessitate frequent opening and closing of the cooling-chamber containing the barrels of beer, &c. y
The object of my invention is to prevent the escape of the cold air from the ice-box and the access of the warmer exterior air to the ice-box when the cooling-chamber containing the barrels ofbeer, &c., is opened, and also to insure a free circulation 4when the said chamber is v for the barrels,
ing-chamber :is for the reception of valso showing volvlng cover closed throughout said parts of the ice-box.
My invention consists of a cooling-chamber suitable bench for the kegs, &c., which coolcommunicates with an ice-chamber and has a sliding bottom and a revolving cover or front, which is yeonnectedgwith the sliding bottom of said chamber, so as to close or open (as the case may be) a chamber below the cooling-chamber. The said lower chamber bottled beer and ale and other articles to be cooled.
rlhe invention also consists in providingr openings for the faucets partly in the revolving cover, and in other details of improvement hereinafter more fully described.
In the accompanying drawings, Figure 1 is a vertical cross-section of my improved icebox with -a beer-keg in position and the cooling-chamber for the kegs closed, so as to permit a free circulation of cold air throughout the ice-box. Fig. 2 is asimilar view of the icebox with the revolving coverof the keg-chamber thrown back to open said chamber and at the same time prevent the escape ,of the cold air and the admission of warm aiA said view the connection between the reand the sliding bottom of the coohng-chamber. Fig. 3 is a partial front vlew of the box. i; f
Referring to the drawings, A is ai box or case having in its upper portion anice-chamber, B, provided with a grated ioor or bottom,
chamber and other kegs, &c., provided' with a.
a, andin the top or front of the case isasuitable door, b, to give access to the ice-chamber B. Below the ice-chamber the case A is made broader, so that the front b of the case below the ice-chamber B projects forward of the front of the ice-chamber.
C is the cooling-chamber or receptacle for the kegs of beer, ale, &c. In the chamber C is a bench or support, D, placed horizontally. The bench D is composed of two iiat portions, d d', extending from the front b ot the case back to a little more than half the depth ot the lower part of case A, where a right-angular back portion, e, is joined to the rear edge ot the part d. Between the parts d and Il is a longitudinal opening, j', and on top of partd is the sliding bottom g of the coolingchamber, which is adapted to slide forward against the part d, so as to cover the opening and to uncover said opening by sliding against the back c. Each side B of the case inclosin g the chamber Gis projected forward to or beyond the front b.
Dis the revolving cover or front of chamber C. `Said cover or front is formed of' the segment of a cylinder of a length as nearly as possible equal to the width of the case between its side walls, or, in other words, of about the same length as the chamber O.
Each end of the cover D is provided with an end piece, E, which abuts against the in side of the side B', and is connected with the side B by a pivot, such as is shown at fi, so that the said end E and the cover D will turn freely on said pivot. The pivots connecting the end pieces, E, with the sides B form the center of the circle, of which the cover D is a segment.
F is a lining-piece placed against the inside of eachside B', and havingits upper edge curved to make a close connection with the curved edge of the end E when the cover is opened4 or closed, as shown in Figs. l and 2.
G is a rope or chain passed through or otherwise attached to the end piece, E, just above the pivot t'. One end of this rope G is carried down between plate F and side B of the case in front of the pivot i, around and under the pin or pulley j, and is attached to the front edge of the sliding bottom g, and the other end of said rope is carried down behind the IOO pivot fi, around and under a similar pin or pulley, j', and likewise attached to the front edge ot the sliding bottom.
By drawing on the front end of cord G the sliding bottom g is moved over the opening f, and by drawing on the back part of said cord the bot-tom gis moved back from over the said opening. Any other suitable mechanism for connecting the sliding bottom g with the ends of the revolving cover may be substituted for that just described.
But one end E of the revolving cover D' is shown; but the other end is arranged in'precsely the same way as the one shown.
The sliding bottom gat the end (not shown).
is connected with the adjacent end E of the revolving cover in the same manner as the one shown, so that the said sliding bottom will be operated at both ends simultaneously.
Below the chamber C is a chamber, H, which may be used for bottled ale, beer, and other articles to be cooled.
Access is had to chamber H through a sul table door on the sides or front ot' the case A, said door being shown in dotted lines.
The operation of the apparatus is as follows: Ice is placed in the chamber B, and the keg I is laid on the bench D, with its rear or inner end resting on the upright backe of the bench, whereby the keg is held in an inclined position, with the spigot lying in a semicircular notch, o, in the top of front b', and projecting ont at the front ot' the case. The revolving cover or door D' being now drawn forward to the position it occupies in Fig. l, it extends from the top of the front b of the case to the bottom edge, h', of the front of the ice-chamber B, thereby closing the chamber C. In the lower edge, u, of the said cover D' are semicircular notches o', coinciding with the notches o, into which notches o' the spigot enters when the cover is Ashut down. By drawing forward the cover D' in this manner the rope G is caused to draw the sliding bottom g back, so as to leave the opening f uncovered, as in Fig. 1. Thus arranged the cold air from the ice in chamber B passes down through the grated loor a and circulates through chamber C, around about the keg I, and passes down through the opening fand space J, between t-he bench D and the back of the case A, into the chamber H, where it serves to cool articles that may beplaced in said chamber.
The direction the cold aircan take when the ice-box is thus arranged is indicated by the arrows, whereby it is plainly shown that a complete circulation of the cold air through the chambers C II is obtained, and at the same time chamber C is closed by the revolving cover D', so that no cold air can pass to the outside from said chamber, nor can any warm air enter it from the exterior.
Now, if it becomes necessary to open chamber C to remove the keg to place another one on the bench, or for any other purpose, the revolving cover D' is thrown back into chamber C behind the keg, so that its edge n will connect with the bottom edge, h', of the front of the ice-chamber B, and its edge-fn' will be in contact with the back of bench D, as shown in Fig. 2, and b'y this movement of cover D the rope Gr, acting on the sliding bottom g, draws the said sliding bottom forward, so as to cover the opening f, as in Fig. 2.
In this way the front of chamber C and the bench D are exposed, so that the keg can be removed, if necessary. however, lthat part ot' chamber C back of cover D' is shut in by the said cover, so that no cold air is permitted to pass outside from the ice-chamber, nor can any pass out of the opening f, which is closed, nor can warm air enter the ice-box. Consequently, when the cover D' is thrown back to open chamber C at the front, the admission of warm air and the escape of cold air are entirelyr prevented; but when the cover is closed down the cold air is permitted to circulate freely throughout chambers C H.
The notches o o in front b' and cover D', respectively, are given the same inclination as the spigot, so that said spigot will lic in the said notches without restraint and without interfering with the close joining of the edge n of cover D and the top ofthe front b', as shown in Figs. 1 and 3.
This arrangement permits a close and approximately air-tight connection to be made between the front b' and cover D' when the spigots project out, and also allows the cover D to be opened and closed when the spigots are in the keg.
l. The combination of the ice-box having ice-chamber B and coolingchamber C with the revolving cover D', for operation substantially in the manner described.
2. In combination with the ice-box having chambers B, C, and H, the pivoted revolving cover D", substantially as described.
3. The bench D in chamber G, provided with the opening f, in combination with the sliding bottom g and the revolving cover D', which is connected with said sliding bottom g, substantially as described.
The above specification of my invention signed by me this 25th day of December, 1879.
