REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 525,021, dated August 28, 1894. Application filed December 14, 1893. serial No. 493,661- (No model.) I

To all whom it may concern:

Be it known that I, FERDINAND KOEHLER, Jr., a citizen of the United States, residing at Cairo, in the county of Alexander and State of Illinois, have invented a new and useful Refrigerator, of which the following is a specification.

My invention relates to improvements in refrigerators, the obj ects in view being to provide a refrigerator that is accessible to all parts for cleaning and other purposes, and which is designed for use by butchers, families, and others. Various other objects and advantages of the invention will appear in the following descrlption and the novel features thereof will be particularly pointed in the claims.

Referring to the drawings,-Figure 1 is a perspective view of a refrigerator embodying my invention. Fig. 2 is avertical longitudinal sectional view. Fig. 3 is a'detail in perspective of the meat-rack. Fig. at is a transverse sectional view thereof. Fig.5 is a bottom plan view of one of the lower racks. Fig.

3 the present instance adjacent to the upper end thereof a circular metal head 16, the same having a central flanged hub 17 through which 6 is a sectional view thereof.

Like numerals of reference indicate like parts in all the figures of the drawings.

In the practice of my invention I preferably construct the refrigerator cylindrical, though if desired the same may be rectangular in cross-section, and is constructed upon dimen- 810115 in accordance with the use for which the refrigerator is designed.

The refrigerator preferably comprises two sections, a lower refrigerating section 1 and an upper ice section 2, the line'of division being walls, the same being lined with mineral-wool or other non-nd noting packing, the interiors of the sections being metal-lined, as is usual. The upper section is provided with a top 4, and at its front side with a pair of doors suitably hinged and provided with proper fastenings. An ice-rack 6,.is in the bottom of the upper section, and to this icechamber above the rack the doors 5 give access.

The center of the ice-rack is provided with a drip-opening 7, and the same communicates with the upper end of a hollow pipe 8 whose lower end is journaled in the bottom of the lower section and projects below the same. At its lower end the pipe is preferably provided with a sprocket-wheel 9, and a chain 10 connects said wheel with alarger sprocket-' rotate the shaft Stogether with the shelves it carries by hand.

It is my intention to provide the drip-pipe 8 with shelves in accordance with the use to which the refrigerator is to be put, as for instance if it is designed to be used by a saloon and intended merely for bottles, a solid or a cast-metal open shelf 14 would be employed; if it be intended for use by a retail butcher I would provide a shelf similar to that indicated by the numeral 15." These, however, as before stated, will depend entirely upon the use for which the refrigerator is designed.

Upon the outer shaft or pipe 8 I secure in a binding-screw 18 is passed, the inner end of the latter impinging upon the hollow shaft or drip-pipe 8. At intervals upon the upper side of the head 16 I locate pairs of perforated bearing-lugs 19, and extend through the entire series of lugs a circular pintle-wire 20. Between each pair of lugs upon thepintlewire I pivot a spike 21, whose outer free end is pointed so as to receive steaks, chops, and other out meats. The inner end of each spike is flattened as at 22, while the heel thereof is rounded as at 23, so that the spike may be swung to a vertical position beyond which it cannot pass or may be lowered to a horizontal position, it being regulated in the latter by means of the adjustable screw 24; which is located under each of the spikes 21 in threaded perforations 25 formed in the metal head. r

The shelves 14 below the meat-shelf herein described are preferably cast-metal and formed in halves or sections 26, each'section or half having a half round opening at its center for embracing the shaft 8 and being provided with lugs as at 27 to receive U-- shaped binding-clamps 28 through which and the lugs screws 29 are passed. These shelves have a central flanged hub 30, and bindingscrews 31 or pins pass therethrough and impinge against the hollow shaft or drip-pipe 8. These shelves are preferably supported at their peripheries by means of. a series of balls 32 which are located in an annular groove 33 formed in annular rest-rings 34 supported by the internal Wall of the refrigerator.

Opposite the several shelves the casing 1 is provided with a vertical series of hinged doors 35 by means of which access may be had to any one shelf Without exposing the contents of the others. The lower shelves are intended to support bottles, butter, lard, and other heavier articles, while the upper shelf containing the spikes is intended to support cut meats, game, 850., as will be obvious.

It will be seen that through themedium of the crank-shaft 12, the shelves maybe revolved so as to expose any portions .of the same .opposite the door-openingsg and, furthermore, that the entire refrigerator may be cleansed. thoroughly by opening all the doors to. give access to the cleaner. The manner. of mounting the shelves insures an. easy operation of the same regardless of the weight of the articles contained thereon.

ter from the ice will pass through the opening 7 inrthe ice-chamber, and into the upper. end of thehollow shaft or drip-pipe 8, coursing down the latter and finally being emptied into any receptacle'that may be placed under the lower end. of the pipe.

Variousmeans may be devised'for.securingv the pipe- 8 rotatably to the lower end of the lee-tank or. shelf, but I prefer to interpose betweenthe upper. end of the pipe and the shelf, a flaring ventilator and drip device 35.. This.

drip device consists ofa series of concentrically arranged flaring rings 36, which are decreasedln thelr respective diameters toward the'lower endof the series, and are nested together and spaced apart by means of intermediate metal straps,37.

It will be seen that there occurs between each two rings an annular air-space to-allow the cold air to freely distribute itself into the it and the wall of the casing. This space I' have indicated as 40 and its bottom has per-' forations 41.

It will be observed that the drip from the ice will course down the receptacle35, and finally into the pipe 8, from which it is discharged in a manner before stated. The tendency of the cold air being to fall or seek the lower endof the casing, will cause said air to In. practice it will be observed that the wapass through the annular openingsintermediate the rings and beeomediffused. The Warm air, on the contrary, has a tendency to rise and will pass through the openings 41 into the annular space 40 and will be prevented from actual contact with the ice contained'in the chamber, by the interposition of the wall-39, heretofore mentioned. The

water of condensation caused by the meeting of the hot and cold currents will flow from the wall 39 into the drip receptacle in the same manner as the drippings from the ice.

I do not limit myinvention to the precise details of construction herein shown and described, but hold that I may vary the same to any degree and extent within the-knowledge of the skilled mechanic.

Having. described my invention, what I claim is- 1. In a refrigerator, the combination of an the combination with thevertical rotary shaft of a sectional perforated shelf mounted on saidshaft and comprising separate duplicate sections or halves: provided at their meeting edges with abutting perforated lugs, U- shaped binding clamps 28 embracing said lugs, and' screws orubolts arranged to-pass through said clamps and abutting lugs,.said sectional. shelf being furtherv provided at the center with a flanged hub to embracethe shaft, bindingv screws. arranged. to pass through said hub and impinge against the shaft, and aball bearing support for the edge of said shaft substantially as set forth.

3. In a refrigerator, the combination with a shaft 3. metal head located thereonand provided upon its upper side with a series of pairs of perforatedlugs, a pintlewirearranged in the lugs, spikes arrangedbon the wire and having their inner ends squared and their lower corners rounded, and a seriesof setscrews threaded in perforations in the heads under-the spikes, substantially as specified.

4.. In a refrigerator of theclass described, the combination with. a cylindrical casing, of the ice shelf arranged within the top part of said casing and provided with a centraldrip opening, and with a series of ventilatingopenings near its edge, an inner annular wall surmountin-g the ice shelf torinclose an annular chamber communicating at thebottom with the openings near the edge of theiceshelfia funnel shaped drip receptacle arranged beneath-the ice shelf, anda verticalhollow shaft arranged to communicate at its upper end with the bottom of said drip receptacle, substantially as set forth.

5. In a refrigerator, the combination with the superimposed ice-chamber, and the lower drip-pipe arranged in line with the opening in the chamber, of the intermediate drip-receptacle, the same consisting of a series of annular flaring rings connected to each other and producing intermediate spaces, the lower ring terminating in a hollow bearing-stud, for

receiving in a rotatable manner the upper end of the aforesaid pipe, substantially as specified.
