REFRIGERATOR.

Application filed January 19, 1911.

Specification of Letters Patent.

atented Aug. 22, 1911. Serial No. 603,554.

To all whom it may concern:

Be it known that I, ITILARY N. Ilonconn, a citizen of the United States, residing at Elkin in the county of Sorry and State of North Carolina, have invented certain new and useful Improvements in Refrigerators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in refrigerators.

One object of the invention is to provide a refrigerator in which food may be preserved without the use of ice.

Another object is to provide a refrigerator of this character having means whereby the same may be readily lowered into and raised from a cellar well or hole in the ground provided to receive the same in which the food will. be kept cool when the refrigerator is lowered therein.

In the accompanying drawings: l ig rure 1- is a perspective View of my improved refrigerator showing the doors closed in full lines and open in dotted lines; Fig. 2 is a front view of the same with the front of the casing removed; Fig. is a vertical cross section on the line 3-3 of Fig. 2 showing the upper section of the food receptacle secured in elevated position; Fig. t is a similar view on the line 4tt of Fig. 2 show ing both sections of the refrigerator in a lowered position.

In the embodiment of the invention I pro vide a cabinet or closet I which may be of any suitable size and shape and which is open at its lower end and adapted to be secured over an opening in the floor of a room beneath which is a cellar or hole 2, dug in the ground. The hole 2 is of suitable depth for keeping cool the food or other articles let down therein by the mecl'ntnism hereinafter described. In the upper portion of the cabinet 1 and spaced a suitable distance from the top 3 thereof is a transverse partition 41 in which are formed slots 5. The front of the cabinet is provided with an upper opening (5 and a lower opening 7. The upper opening 6 is closed by a hinged horizontally swinging door 8 while the lower opening is closed by a vertically opening downwardly swinging door 9. The door 9 is provided on its lower edge with hinge members 10 which are pivotally and slidably engaged with a hinge bar 11 secured to the front side of the cabinet below the opening 7 and extending some distance beyond one side of the same as shown. By thus hinging the door 9 the latter may be swung downwardly to a horizontal position and slipped back along the rod 11 to one side of the opening 7 and when in this position is adapted to be supported by a leg member 12 which is hingedly connected to the outer side of the door and is adapted to be swung downwardly to form a support for the outer end of the latter when in an open position said door thus forming a table or support upon which goods may be placed prior to or after being removed from the refrigerator hereinafter described.

The side pieces of the cabinet are secured together near their upper ends and between the top piece 3 and partition l by transversely disposed tie bolts 13 having turn buckles 12-3, while the front and rear sides of the cabinet are secured to the front and rear edges of the side pieces by screws or other suitable fastening devices whereby the cabinet may be readily knocked down or taken apart when desired. In the cabinet adjacent to its opposite sides and midway between the front and back thereof are ttll'ttl'lgttl vertically disposed guide rods t l the upper ends of which project through the partition 1 and top piece 3 and are rigidly secured in the latter by clamping nuts The lower ends of the rods project down into the cellar or hole in the ground and have on their lower ends stop nuts 16. Arranged between and slidably connected to the guide rods 141; are upper and lower cars or food receptacles l7 and 18, said receptacles being preferably in the form of rectangular boxes open at their front sides and having arranged therein shelves 1!). The cars or receptacles 17 and 18 have on their opposite sides guide plates 20 provided on their upper and lower ends with right angularly projecting apertured guide lugs 91 through which the guide rods 14 project and whereby said cars or receptacles are slidably supported on the rods.

Secured at one end to the top of the lower receptacle or car 18 is a raising and lowering cable 92, said cable passing up through apertures .23 formed in the top, bottom and shelves of the upper receptacle 17 and through apertures in the partition 4 and top piece 3 of the cabinet. The cable after passing up through the top piece 3 is passed over guide pulleys 2 f joui'naled in suitable bearings 011 the top piece 3 and thence downwardly through said top piece and partitionA adjacent to the inner surfaceof one side of the cabinet. The cable after passing down through the partition 4 is passed around a pair of friction pulleys 25 and 26 and then passes downwardly through the lower open end of the cabinet and has secured thereto a counter balancing weight 2? whereby the weight of the cars or receptacles is balanced.

The shaft of the pulley 25 projects through the adjacent side of the cabinet and is provided with a crank handle 28 whereby the pulley 25 may be operated to raise or lower the receptacle by the frictional engagement of the operating cable with the pulleys 25 and '26.

Fixedly mounted on the shaft of the pulley 25 is a ratchet gear 29 with which is adapted to be engaged a reversible locking pawl 30 whereby the pulley 25 and the shaft thereof may be locked at any desired position when raising or when lowering the receptacle thereby supporting the latter on the rods 14 at any desired elevation. The pawl 30 comprises a pivoted plate 31 having 011 its outer end a pair of apertured lugs in which is revolubly mounted the reduced cylindrical inner end 33 of the pawl whereby the outer end thereof may be turned in one direction or the other. The turning movement of the outer end of the pawl in the lugs 32 is limited by a stop stud 3% arranged in the end of the pawl between the lugs 32 as shown. In the upper and lower edges of the outer portion of the pawl are 'formed oppositely projecting ratchet teeth 35 and 36 one or the other of which is adapted to be engaged with the ratchet wheel 29 so that the latter may be locked against revolution in either direction. A keeper member 30 is secured to the wall of the cabinet in position to receive and guide the free end of the pawl 30 during its vertical movement.

It will be noted that the upper receptacle 17 is not directly connected to the raising and lowering cable 22 but when in released position rests on the top of the lower car or receptacle 18 and is raised and lowered by the movement thereof. The upper receptacle 17 is primarily intended for use as a kitchen safe and to this end is provided with means for detachably supporting the same in the upper portion of the cabinet. The supporting means for the upper car or receptacle consists of a pair of upwardly projecting supporting hooks 37 which are preferably formed integral with and bent upwardly at right angles from the opposite .endsof. an attaching plate 38' secured to the upper side of the receptacle 17. W hen the receptacle 17 is in an elevated position the hooks 37 will project through the slots 5 in the partition l and are adapted to engage crank loops 39 formed in a transversely disposed supporting shaft 1-0 which is revolubly mounted in the opposite sides of the cabinet and projects beyond one side thereof. The projecting end of the shaft 10 has formed thereon a handle 4:1 whereby the shaft may be rocked to swing the crank loops 39 to operative and inoperative positions for receiving or disengaging the hooks 37 on the receptacle 17. When the shaft 1-0 is turned to swing the crank loops to vertical position and the receptacle 1? brought up to its highest elevation the pivoted hooks on the upper ends thereof will spring into engagement with said loops thereby holding the receptacle in an elevated position. When it is desired to lower the upper receptacle with the lower receptacle the shaft is turned downwardly to disengage the loops from the hooks thereby permitting the receptacle 1'? to lower on and with the lower receptacle 18 and to be raised thereby when the latter is drawn up by the raising mechanism hereinbefore described.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as defined in the appended claims.
