REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 461,006, dated October 13, 1891.

Anplication iiled January 16, 1891. Serial No. 377,940. (No model.)

To a/ZZ whom, t may concern,.-

Be it known that I, ORRIN M. WHITMAN, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Refrigerators or Butter-Coolers, of which the following` is a specieation.

The nature of the invention is fully described below, and illustrated in. the accompanying drawings, in which- Figure l is a front elevation of a buttercooler embodying my improvement. Fig. 2 is a vertical section on line Fig. l. Fig. 3 is a horizontal section on line y, Fig. 2.

Similar letters of reference indicate like parts.

A represents the chest containing the lower or store-room chamber B, provided with the doors B, and ice-chamber C, provided with the doors C', all constructed as usual. Bctween the ice-chamber C and the lower chamber B is the chamber D, whose floor D has its front edge provided with a hinged shelf D. The door D is slightly below the platform E, which forms a portion of the top of the lower chamber B.

II II are two glass panes, each semicircular 1n horizontal section and each provided with a frame consisting of the upright pieces Il andthe curved lower and upper pieces H H. The side pieces II are centrally pivoted at 71y to the sides A of the chest and the dividing-post A.

I I are semicircular hoods or caps secured to the front of the chest over t-he windows above described.

When the swinging windows are closed, they fit upon the platform E and against the inner sides of the hoods I, so that no warm air reaches the inside of the refrigerator. \Vhen they are swung up into the position illustrated by broken lines in Fig. 2, they tit against the semicircular under edges of the hoods I, and their upper ends lie against the front wall of the ice-chamber C. A keg of butter may lie at an angle on the floor D and platform E, as shown by broken lines V in Figs. l and 3, or it may stand on A cord K extends from the swinging shelf D to the part II of the sash above its pivoted point. Then the sashes or panes are closed, the shelf D is raised, allowing circulation of air from the ice'chamber C to the store-room B. Then the sash is opened, the shelf D drops by gravity and no air from the outside can enter the chamber B. Thus it will be seen that when a sash or window is raised into the position shown in broken lines in Fig. 2 the top H of the frame rests against the icc-chamber walls, the pane rests against the hood I, and the shelf D drops,

so that no warm air can communicate with the ice-chamber C or chamber B. lVhen the sashes are closed, the tops II rest against p the inner side of the hoods I and the bottoni pieces Il rest on the platform E, completely closing the cooler.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

In a refrigerator or butter-cooler, the combination of the hoods or caps I, secured to the front of the chest above the windows, said hoods or caps beingselnicircular in horizontal section and provided with concave under edges, as shown, adapted to lit over said windows when they are swung up, the windows consisting of the panes II and frames II II II, said frames being pivoted to the wall of the chest A A', and said windows being semicircular in horizontal section and swinging on a horizontal axis from a vertical closed position to a horizontal openA or raised position, and the ice-chamber C, constructed and located as described, whereby when the windows are closed the bottom pieces Il of the frames rest on the platform E, and the top pieces II of the frames rest againstthe concave inner sides of the hoods, and when the windows are open the semicircular panes II rest against the concave under edges of the hoods and the top pieces Il Iest against the wall of the ice-chamber C, so as to su bstantially cut oft' the entrance of Warm air to the ice-chamber, substantially as set forth.
