SPECIFICATION forming part of Lett ers Patent No. 520,695, dated May 29, 1894. Application filed June 26, 1893. Serial No. 478,811. (No modelg) To all whom t may concern,.-

Be it known that I, LoREN B. MCCLANA- THAIT, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Refrigerators, of which the following is a full, clear, and exact descriptlon, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to an improved refrigerator of that class in which cold air is caused to circulate about the material to be cooled, by the action of a fan, and it consists in the novel construction, combination and arrangement of parts hereinafter described and designated in the claims. The object of my invention is to provide an 1m proved refrigerator of this class which shall be portable for use especially in households, meat-markets, and sh stalls, which shall be hlghly eflicient in operation, economical inv the consumption of ice, of low cost, and which shall have improved means for artificially setting up circulatory currents of cold air about the substances and material to be cooled.

In the drawings: Figure 1 is a sectional elevation of my improved refrigerator, taken o n the line 1-1 of Fig. tional plan view of same taken on tlie line 2-2 of F1g. 1. Fig. 3 is asectional transverse elevation taken on the line 3 3 of Fig. 1. Fig. 4 1s a perspective view of oneof a series of detachable sliding-receptacles, detached, and which is made use of. in carrying out the invention.

1 indicates a mainchamber, vided with top, bottom, side and end walls which are preferably double and have sheets Of paper or other non-heat-conducting material 2 located between them. These walls,

however, may be constructed in any known manner. The main-chamber is divided by a horizontal partition 3 having a series of slats 4 upon its upper surface, into an upper refrigerating-chamber 5 anda lower chamber 6. A vertical passage 7 is formed at the end of the partition 3, so that the adjacent ends of the upper and lower chambers are thereby connected, said passage 7 being located between said ends of said partition and the adjacent end of the refrigerator. The sides of the partition 3 extend into contact with the Isides of the refrigerator.

which is pro-A An ice-receptacle 8 having closed sides and bottom and an open top, is provided with a metallic inner lining 9, and is located transversely of the main-chamber in the upper part thereof with one of its sides in contact with the end of the partition 3 which is opposite the vertical passage 7, so that the ice receptacle forms a tight joint at its point of connection with said partition and prevents upward or downward passage of air thereat. This ice-receptacle has a length corresponding to the width of the interior of the main chamber, and its ends are preferably in contact with the sides of said chamber. The plane of the bottom 10 of said ice receptacle is preferably a little below the plane in which said partition 3 is located. The ice-receptacle 8 does not extend upward to the top of said chamber, but an open space 11 is formed above the top of thesaid ice-receptacle.

12 indicates a door, which is provided with hinges 13 and handle 14 and hinged to the top of the main chamber so as to open directly above the open top of the ice receptacle, for the purpose of affording access to said receptacle, in placing ice therein, cleaning, &c.

15 indicates a hinged deiiector or valve,

'which is hinged at its upper edge, by means of suitable hinges 16, to the under surface 0f said door, so that its lower edge depends at an angle to said door, and maybe thrown into contact with the ice in said ice-receptacle, and-so as to more or less close the passage 11 between the upper side of the refrigerator and said ice receptacle, for apurpose hereinafter mentioned. The length of this hinged deliector is alittle less than that of the ice receptacle. (See Fig. 3.) y

A Ysuitable rope, cord, chain or other common iieXible device 17 has its lower end secured to the upper side of the deflector 15 adjacent the lower edge thereof, and passes loosely through a hole or passage 18 formed in the door 12, and is wound around or otherwise secured to a common hook or other fastening 19 fixed upon the outer surface of said door adjacent the handle 14 thereof, for a purpose hereinafter mentioned.

A vertical partition 20 extends transversely across the interior ef the refrigerator with its ends in contact with the vertical sides thereof, with its lower edge in contact with IOO the bottoni thereof, and with its upper edge in close contact with the bottom 10 of the ice receptacle, so that a vertical passage 21 is formed in the end of the refrigerator that is opposite the passage 7 at the opposite end of said refrigerator. This passage extends the full width of the interior of the refrigerator, forapurpose hereinafter mentioned. Formed in this vertical partition 2O at about the center of the width and height thereof, is an opening 22, in which is located a revoluble fan 23 having arms or blades which revolve in a vertical plane and force the air contained in said passage 2l through said opening into the lower refrigerating chamber (i. This fan is preferably mounted upon the horizontal revoluble shaft 24 of a common electric motor 25, which is mounted upon a horizontal platform 26 in and extending across the lower portion of said passage 21, and connected in the usual manner by means of suitable electrical connections 27 to any common battery 28 or other source of electricity, so that said fan will thereby be revolved at a rapid rate of speed. The source of electricity may be common batteries placed within the lower portion of the passage 21 beneath the horizontal platform 2G, or located upon the eX- tcrior of the refrigerator.

29 indicates a deflector that is V-shaped in cross section and fixed vertically beneath the ice-receptacle S centrally of the length thereof in longitudinal alignment with the opening 22 in the vertical partition 20, so that the salient angle of said deiiector is located adjacent said opening in alignment with the center thereof. This V-shaped deflector is located directly in the path of a current of air created and projected by the fan 23, so that said current strikes said detlector and is thereby divided into two separate currents.

30 indicates a vertical drain pipe for the ice receptacle, the upper end of which communicates with the interior of said receptacle, and the lower end of which projects into the space 31 beneath the refrigerator, said pipe passing through an opening 32 formed in the bottom of the refrigerator, and passing upward within the space inclosed by the walls of the V- shaped deiiector 29, so that it is thereby protected from bending and indentations during use.

33 indicates a door, closing an opening in the end 34 of the refrigerator directly opposite the electric motor 25 and the opening 2 in the vertical partition 20. This door is provided with common hinges 35 and a handle 3G, so that it may be opened and closed, to provide access to themotor and other devices contained within the lower portion of the passage 21. i

37 indicates a series of guide bars which are angular' in cross-section and fixed within the lower chamber G so as to extend in a horizontal position across the same and support a series of detachable sliding receptacles 38.

The guide-bars 37 are preferably arranged as shown in horizontal parallel rows, one row above the other, and supporting one series of the receptacles 38 above another series. There are four series of receptacles, or more, two or more series sliding out of openings 39 in one side of the refrigerator, and two or more series sliding out of openings 40 1n the opposite side of said refrigerator.

The series of receptacles on one side o f the refrigerator, in a given plane are in horizontal alignment with the receptacles on the opposiie side of the refrigerator in the same plane, so that when the receptacles on both sides in a given plane are pushed inward to the limit of their inward movement, their inner ends lie closely adjacent. The front 41 of each receptacle is provided with a marginal flange 42 which engages and overlaps the outer surface of the refrigerator when said receptacles are at their limit of inward movement. Each receptacle is provided with a suitable handle 43 upon its front. The side bars 44 of each receptacle are provided with opposite cut away portions 45 in their upper edges, for a purpose hereinafter mentioned, while the upper edge of the inner end 4G of each sliding receptacle projects upward a distance above the upper edges of said side bars so as to form a stop 47 which contacts with the inner surface of the refrigerator wall, and limits the outward movement of said receptacles, except when the same are to be detached. The side bars 44 have their lower inner corners 48 rounded off, and their inner ends project a distance inward beyond the ends 4G ofthe receptacles. The inner surface of the bottoms of these receptacles may be provided with slats 4i), so as to hold the meats, vegetables, dsc., a distance above said bottom. A receptacle 3S is mounted to slide in an opening 50 formed in one side of the'refrigerator, seas to be located in the upper chamber 5 above the partition 3. rlhe construction of this receptacle 38, and its mountings is identical with that of the receptacles located in the lower chamber, with the exception that this receptacle is preferably of larger size, so as to extend about the full length of the horizontal partition 3.

51 indicates a door, for affording access to the upper chamber 5. This door is located in the side of the refrigerator opposite the side in which the receptacle 38 of the upper IIO chamber is located, and is to be provided with the usual fastenings.

52 indicates a vertical partition which is mounted upon the upper side of the horizontal partition 3 and extends in a direction longitudinally of the refrigerator, with one of its ends in contact with the adjacent side of the ice receptacle 8 and with its opposite end flushV with the adjacent end of said horizontal partition.

53 indicates a meat-rack mounted upon brackets 54 projecting from the side of the vertical partition 52 which is adjacent the door 51, so that said meat-rack is mounted `and extends parallel-with said partition and with its upper edge about in the same plane that the upper edge of said partition is in.

55 indicates aseries of common meat-hooks which are secured to the meat rack, so that pieces of meat and other material may be suspended therefrom within the upper chamber of the refrigerator out of contact with the partition 3, and be accessible by way of the door 51.

The Vertical walls of the refrigerator may be made transparent in a common manner, by having plates of glass set in them.

The operation is as follows: A supply of ice is placed i-n the receptacle 8 by way of the door 12 in the top of the refrigerator, and said door is closed and the hinged defiector 15 is swung downward by means of a flexible connection 17 and its lower edge is brought into contact with or separated a distance from the ice in the recptacle, according to whether a more or less rapid circulation of air above said ice is desired. The motor 25 being supplied with a suitable current of electricity in the manner hereinbefore described, rapidly revolves the fan 23 in the proper direction, and a current of air is thereby projected through the opening 22 in the vertical parti-y tion 20, and impinges upon the V-shaped vertical deilector 29 and is thereby divided into two currents, one of which is forced over the receptacles 38 through the spaces formed therein by the cut away portions 45 in said receptacles, and around and under the samein the lower chamber 6, and then said air passes upward by way of the vertical passage 7 at the end of the horizontal partition 3,into the adjacent end of the upper chamber 5, and around and over the receptacle 38 therein, and around and over the articles to be cooled therein, and thence passes toward the ice receptacle, and comes in contact with the inclined deflector 15, and is thereby brought into intimate contact with the ice in said receptacle and very thoroughly cooled, and thence passes between said ice and said deflector into the 'vertical passage 21 and thence is drawn through the opening 22 by the fan 23 and so on,-a continuous and rapid circulation being kept up in this way as long as the fan is in motion. A suitable electric switch 56 is connected to the motor, for controlling the movements of the fan, any coinmon motor being employed as described. The receptacles 38 are detachable, by drawing them out until their stops 47 come in contact with the wall of the refrigerator, and then lifting their outer free ends upward, when the rounded corners 48 will slide past and out of the lower side of the openings in the refrigerator, and then the stops 47 may be disengaged from said wall, and the receptacles be detached. The manner of replacing the receptacles is j ust the reverse of this, that is, the inner ends of the receptacles are placed in the openings inthe walls of the refrigerator7 while their outer ends are elevated as shown by dotted lines and the stops 47 are made to engage the inner surface of the walls, and then the outer ends of the receptacles aie lowered to normal position and the receptacles are to be slid in upon the guides 37.
