To all whom, t may concern.'
Be it known that I, CHARLES MOORE, of Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Refrigerators, of which the following is a speciiication.
My invention relates to means of excluding the outer air from the refrigerator, and to Io means of readily removing and inserting the filling.
In the accompanying drawings, Figure 1 isv a perspective view of a refrigerator containing my improvements; Fig. 2, a central vertical cross-section of the same; Fig. 3, a top view ofthe same with the covers removed, Fig. 4, a horizontal cross-section'of the same just above the water-coil.
A. is an outer wooden case, having an outer 2o wooden cover, B, hinged thereto in the usual manner by hinges C.
D is a box of sheet metal,l zinc preferably, soldered where the edges of the sheet metal meet or lap, and open at the top, and divided 2 5 by a horizontal partition, D', also sheet metal, into two compartments-a food-box, D", and an ice-box, D"said partition being joined by solder in an air-tight manner, to prevent the- I passage of air lfrom one compartment to the 3o -other when one of them is opened. The box D has another opening on the front side into the lower compartment, D3, the edges of the zinc or sheet metal of the box around the lower opening being soldered to a rectangular door- 3 5 casingE, of iron, in an air-tight manner. 'Ihe box D thus formed is lowered into the case A from the top upon a suitable-fillingsay of spent tan-bark or pulverized charcoal-and the spaces between the sides of the box and the case 4o are then filled with similar material to that on which the `box rests. Four slats, F, about an inch thick, are then placed around the top Yof the box, between it and the case, on top of the lling.. By removing the slats the filling may be removed, if wet from accidental leaking of the box; or the space below the slats may be lled up in case the filling should settle down. The inner cover, G, is an inverted shallow wooden box, over the bottom of which a sheet, G', of
5o zinc is placed, the space between the zinc G' andthe top of said cover G being an air-space, or preferably filled with spent tan-bark. Below (N o model.)
the inner cover, and secured to the same, is a gasket, G2, of rubber or similar elastic material. The upper edges of the box D project slightly above the case A, so that when the cover G is shut down these upper edges are embeddedv in the rubber GZ and prevent air from entering between the box and cover G. The cover G is hinged to the rear sla-t, F. A bow-shaped 6o spring, B', is secured by its middle to the under side of the upper cover, and its ends press down upon the cover G and close the latter more effectually. The inner door, IVI, is of iron plate, and has around its outer edge, on its inner face, a gasket, H', of rubber of considerable thickness, which, when said door is shut, presses against the casing E and makes an air-tight joint between said door and cas ing, said door being hinged to said casing by 7o hinges E'. This inner door is fastened by a bar or latch, I, and a catch, K, respectively, secured to the door-casing E on opposite sides of said door, the latch being pvoted or hinged at E2, and held near the door, but not close to it, by the strap L, secured to said door above and below said latch. A hole, I', in the middle of the latch or bar I is screw-threaded, and in this hole turns a screw, S, which, after the latch is engaged with the catch, is turned 8o by hand to thrust against the door H and push said door toward the casing and compress the gasket H'. An outer door, N, is hinged to the case A, and is bolted 'or latched in any usual manner, and has a central depression, N', to 85 admit the head of the screw S. The bottom of the box D slants down toward the middle, and has grooves V, which lead from the corners to a central downward depression V', and into a Siphon or trapped pipe, WV, which runs 9o through the filling and the bottom of the case to lead away the waste water. A coil, R, of pipe may be placed on the bottom of the box D, and the icc may be placed thereon, and such coil being connected with the supply- 9 5 pipes of the house, water drawn through the coil will be found to be nearly ice-cold.
The refrigerator above described may be mounted on casters, sol as to be easily moved.
The improvements herein claimed are ap- IOO plicable to a rcfrigerating railway-car.
