JULIUS A. I-IENKEL, OF GREENVILLE, MICHIGAN.

REFRIGERATOR.

SPECIFICATION forming' part of Letters Patent No. 505,358, dated September 19, 1893.

Application filed April 27, 1893.

To afZZ whom it may con-cern.-

Be it known that I, JULIUs A. HENKEL, a citizen of the United States, and a resident of Greenville, in the county of Montcalm and State of Michigan, have invented certain new and useful Improvements in Refrigerators; and I do declare the following to be a full, clear,

Y and exact description of the invention, `such as will enable others skilled in the art to which 1t appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specication.

Figure l is avertical longitudinal section of the refrigerator. Fig. 2 is a horizontal transverse section of the same on the line Fig. 1. Fig. 3 is a vertical section on the line /y-y, Fig. l. Fig. 4. is a transverse section on the line w-w, Fig. 3, with a portion b roken away, and Fig. 5 is a detail perspectlve view of the valve-operating mechanism. This invention has relation to certain new and useful improvements in refrigerators, the object being to improve the general constructlon and arrangement of the refrigerator box, and to provide means for securing an effective circulation of air therein, and for keeping foul or warm air away from the ice and provision chambers; and the invention consists 1n the novel construction and combination of parts, all as hereinafter described, and pointed out in the claims.

Referring to the accompanying drawings illustrating the invention, the letter Av des- 1gnates the refrigerator box, which is constructed with an outlet wall a, an inner wall l d', and with a central wall or partition a2, be-

tween said outer and inner walls, and formlng therewith air spaces or chambers b, b. This arrangement of walls and air spaces extends entirely around the box, with the exception of the front, where the three walls are placed closely together without the intermediate air chambers, and at the/top, where the arrangement is somewhat modilied,as will presently be described. The central walls or partitions a2 are held in place by corner cleats c, c, having grooves therein to receive the edges of the Walls, said cleats also serving to hold the inner walls in place, as shown.

Serial No. 472,070. (No model.)

The interiorof the box is divided into two chambers B, B', one above the other, by a transverse horizontal partition C, which is so arranged as to leave an opening d between it and each inner end wall of the box. Said .partition also has a central transverse opening d.

The upper apartment B forms the ice cha mber, and in. this chamber is placed an ice chest D, preferably of metal, and open at the top, and which may be removable. This chest, while it fits snugly against the front and back inner walls d', 0.', does not extend to the end walls of the chamber, but fits between vertical transverse liue boards E, which are held a short distance away from the said end walls The arrangement of formed at each end of the ice chest, said liues forming continuations of the openings d, CZ,

at the ends of the transverse partition C.. In the bottom of said chest is a transverse opening f, which registers with the opening d in the partition C, said opening f being protected by an arched guard plate F, having openings f along its lower edges, and open at the ends.

G designates the cover of the chest D, said cover being shown as attached to and removable with the cover A of the refrigerator `Through this cover G is formed a series of Vertical perforations or openings g, which communicate with the interior of the chest G and with an air chamber or flue I-I above said chest in communication with the flues E",E. The upper ends of the vertical air spaces or chambers b, b', at the sides and end of the box are closed by strips I, secured to the upper edges of the walls. Between the upper wall of the flue H and the outer wall of the cover or top A', is an air chamber or space Jin said cover.

Supported in the ice chest upon rods la, lo, and held away from the end walls thereof a short distance by guards 7o', lo', is an ice box K, open atthe top, and having a grating at the bottom. This box is made removable and is inserted and removed from the chest through an opening L cut through the front walls of the box, and through the wall of the ICO chest. This opening is'closed by a hinged door L', having rabbeted edges, which seat in the edges of the opening in the Amanner of a safe door.

Thelower apartment B forms the provision chamber, and is provided with one or more shelves M, of any suitable material and having means for admitting the circulation of air therethrough. Entrance to the chamber is furnished by means of a door N at the front, said door also having rabbeted edges which have corresponding seats in the walls. The cold air from the ice chamber falls through the central opening d in the partition C into the provision cham ber, the warmer air rising through the openings cl, d, and ues E', E', in the chamber or Iiue H, and through the perforations or openings g into the ice chamber, thus maintaining a continuous circulation.

In order that the passage of air up through the flues E', E', may be prevented when the door N of the provision chamber is opened, I provide the openings d, d, with dampers or valves P, P, which are arranged to slide in guides p, p, on the under side of the partition C, mechanism being provided for causing said valves to close when the door N is opened, and to open when said door is closed, as will now be described.

Pivoted to the under side of the partition C by a common pin are two levers R, R, the shorter arms of which project to a point just inside the inner front wall. The longer arms of said levers extend back and to each is connected one end of a link S, the other end of which is connected to the central portion of one ofthe valves P, a spring 1' interposed between the levers R, R, back of the pivot act'- ing to spread the rear arms of said levers, and keep4 the valves closed. When however the door N is closed, a pointed or V- shaped lug or projection T thereon, centers between the forward arms of said levers, forcing them apart, and drawing the rear arms together, thereby opening the valves, which are thereby held open as long as the door remains closed. When the dooris opened, the lug is Withdrawn from engagement with said levers, and the spring immediately acts to close the valves, so that no outside air can get access to the ice chamber.

W is a Waste pipe which runs from the lower rearportion of theice chamber down and along the rear wall of the provision chamber, and out through the wall thereof, where it discharges into a closed tank W having a drawoif cock or faucet fw.

The inner walls of the provision chamber and ice chamber should be of a non-odorous character.

The construction of the box is such, it will be observed,that it is impossible for the outer air to come in contact with the ice, or with the walls of the ice chamber or chest, so that a small piece of ice will last for a considerable period of time, the provision for circulation being such as to insure the proper lowness of temperature in the provision chamber.

Having described this invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a refrigerator, the boxA divided into two chambers B, B by a horizontal partition C, having an opening d between it and each inner end wall of the box, and a central opening d', an ice chest D in the upper chamber, said chest fitting snugly against the front and back inner walls of the box, but held away from the end Walls thereof to form iiues E situated over the openings d, a perforated cover G for said chest, an air chamber above said cover, and a guarded openingfin the bottom of said chest and registering with the opening CZ in the partition, substantially as specified.

2. In a refrigerator, the combination with the chamber B in the upper portion of the box, and separated from the lower chamber thereof by a partition C having end openings d and a central opening d', of an ice-chest D in said chamber B, said chest fitting snugly against the front and back inner walls of said chamber but held away from the end walls thereof, a flue E at each end of said chest and communicating with the openings d, an opening f in the bottom of the chest registering with the opening d, an arched guard for said opening f, the perforated cover G for said chest, the chamber I-I above said cover and communicating with the flues E', E', and the ice box K supported in said chest and open at the top, and having a grating at the bottom of said box, substantially as specified.
