,3 rear wall 13, sidewalls 14 and 15, horizontal partition 17, and base 18, defining a compressor compartment 20.

i Mounted within the refrigerating compartment 19 is a T-partition 21 extending forwardly from the rear wall 13 stopping short of the front wall 12, and dividing the refrigerating compartment 19 into a refrigerating section 22 adapted to. receive mechanical refrigeration a paratus, a refrigerated section 23 ar- 0' range to receive material to be refrigerated, and 'a humidor section 24 arranged to receive a rece tacle, for the storage of tobacco products," a 1 three sections 22 and 23 and 24 being l all open at the front, thehumidorsection 24 5 being otherwise.completely segregated from the refrigerating and refrigerated sections,

A22 and 23, and the refrigerating and refrigerated sections 22 and 23 being inter-connected by means of circulation apertures25 and 26 T -partition -21.

'43 affording access to the interior Mounted lwithin the refrigerating section 22 is mechanical refrigerating apparatus 27 comprising a brinetank 28 containing a suitable expansion coil, not shown, and provided with a plurality of apertures 29 for the reception of trays 30 for the formation of articial ice under the action of the refrigerating 'apparatus 27, an expansion valve 31 supported on the brine tank 28 and-connected ,to the inlet end of the expansion coil, end turns 32 supported on the brine tank 28 and connected to the outlet end lof the expansion coil and themselves supporting a thermostat 33, a drip pan 34 disposed beneath the brine tank 28 to receive the condensation from the refrigerating apparatus 27 and a drain duct 35 extending from the drip pan 34 throughA the humidor section 24 into the compressor com-l partment 20, and thence to any desired point.-

Closing the front of the refrigerating section 22 is a shield 36 provided with an aperture 37 affording access to the trays 30.-'v

Mounted within the refrigerated section 23 are a plurality of shelves 38 -adapted to support the material to be refrigerated, and themselves supported on brackets 39 and 40 mounti ed respectivelyl upon the T-partition 21 and f the side wall 15.

Mounted within the humidor section 24 is a receptacle 41 supported from the horizontal partition 17 b y means of suitable blocks 42, provided at its forward end with an o ening closing the opening in the forward end ofthe humidor section 24 to thus completely segregate the space 44 within the humidor section 24 exteriorly of the humidor receptacle 41, and provided with av door 45 tightly closing the opening 43. ,Y Mounted within the compressor compartment 20 is a compressor 46 having its inlet.l connected by means of a duct 47 to the end turns of the expansion coil within the refrig` erating apparatus 27 a condenser 48 havin its inlet connected by means of 'a duct 49 to the outlet of the compressor 46-and its outlet con-- nected by means of a duct 50 to the expansion v valve 31,.and an electric motor 51- operatingY the compressor '46 by means of a suitable belt g 52 and energized from'line wires 53 and'54 diate conductor 55.

In the embodiment of my invention herein shown I provide access to the compressor l compartment by means of an opening in the front wall 12 arranged to be. closed by 'means of a suitable door 56, and to the rerigerating compartment 19 by means of' a single openlng 57 affording access at all times to the ice trays and the refrigerated seci tion 23 and the humidor door 45, affording access to the interior. of the humidor receptacle 4 3 byopening the humidor door 45,

and affording access to the entire refrigerating apparatus 27 upon removal of the shield 36, and in the embodiment of my invention herein shown I close thisopening 57 by means of a single door 58` consisting of an inner lwall 59, and anl outer wall 60 spaced from the inner Wall 59, and carrying between the' inner wall 59 and the outer wall 60 a combination lock 61 operable by means of a knob 62 disposed on the exterior face of the door 58 and including abolt. 63 arranged to prevent rotation of-adisc'64 carried by a s aft 65 operable by means of a handle 66 and operating bolts 67 and 68 arranged to extend from the top and bottom, edges of the door 58 into suitable alining apertures 69 and 7 0 in the adjacent edges of the front wall 12 of the refrigerator cabinet 11 to secure the door firmly locked in closed position.

From the above description it will be ob.

Y vious to those skilled in the art that I have those skilled in the art that the particular embodiment of my invention provided mechanical refrigeration means having the expansion means and the control means andthe ice means and the refrigerating section and the refrigerated section andthe humidor section and the material within the refrigerated section and the material within the humidor'section all accessible throughl a single opening, having a single door'for closing this opening, lock. disposed within the walls ofthe door out of communication with the refrigeration compartment and arranged to lock the door closed to thus prevent access to the expansion means and the control means and thev re-l frigerating section and the refrigerated section and the humidor section and the material within the refrigerated section and the material within the humidor section.

At the same time it will also be obvious to herein 'shown and described may be variously changed and modified without departing from the spirit of my invention or sacrificing the advantages thereof,-and it will therefore be understood that the disclosure herein is illustrative only, and that my invention is not limited thereto.
