FREDERICK FISCHL, OF NEW YORK, N.. Y.

CUT-OFF DOOR FOR REFRIGERATORS.

SPECIFICATION forming part of Letters Patent No. 549,713, dated November 12, 1895.

Application filed December 19, 1894. Serial No. 532,281. (No model.)

To all whom it may concern Be it known that I, FREDERICK FISCHL, a citizen of the United States of America, and a resident of New York, in the county and State of New York, have invented certain new and useful Improvements in Ice-Boxes, of which the following is a specification.

My invention has reference to improve ments in refrigerators, such as are usually found in stores for the preservation of milk, butter, &c. In such refrigerators considerable cold air is lost in the frequent opening of the doors, which remain in an open state while the customer is being served, and therefore an increased and unnecessary consumption of ice is involved.

The object of my present invention is to so to each other and having a common platform adapted to support the receptacle and an auxiliary closing-piece adapted to close that part of the door-opening not closed by the inner or follower wing.

The nature of my said invention will best be understood when described in connection with the accompanying drawings, in which Figure 1 represents a horizontal section of a corner of a refrigerator provided with my improved compound door, the door being closed. Fig. 2 is a similar view showing the door open. Fig. 3 is a'sectional elevation looking in the direction of arrow 3, Fig. 1. Fig. 4 is a similar view looking in the direction of arrow 4, Fig. 2. Fig. 5 is a horizontal section on the line 5 5, Figs-l, on an enlarged scale, and illustrating a detail of construction. Fig. 6 is a perspective of a refrigerator with my improvement drawn to a smaller scale.

Similar'letters of reference designate corresponding parts.

Referring now to the drawings, the letter A designates the walls of a refrigerator of a usual construction.

D is the compound door hinged to swing in a horizontal plane by the usual hinges a a. This door, which constitutes the main feature of my invention; consists, first, of a main wing (1 corresponding to the ordinary door and fitting the door-opening from the outside; secondly, of a follower-wing cl arranged at an angle to the main wing and adapted to approximately close the door-opening from the inside, and, thirdly, a platform d secured to the bottom of the two wings and adapted for the reception of the receptacle to be removed from the refrigerator. I have shown the door hinged in the usual manner of hinging such doors to ice-boxes. In this case the follower wing cannot be constructed to completely close the door-opening without interference, and, therefore, I provide an auxiliary part for this purpose. Said part consists of a closing-piece b, hinged at or near the corner of the refrigerator by hinges c and adapted to overlap the adjacent door-opening when closed, as shown in Fig. 2. This closing-piece is connected to and operated by the wing 61- by any suitable known means-such, for instance, as the slotted rail 6 and pin f, shown in Figs. 4 and 5, connected, respectively, to said piece and the wing d. In this example I have shown the wing (1 adapted to enter the door-opening when closed and provided with a cleat g to insure a tight closure.

The door is provided preferably, with a caster h on the main wing (1, adapted to travel on the floor or on a rail especially provided therefor, and with a caster i on the follower wing (1, adapted to travel on a rail or segmentj on the bottom of the refrigerator, all for the purpose of preventing undue strain on the hinges.

The receptacle 0, Fig. 6, is placed on the platform (1 and can then be removed from and returned to the refrigerator with the greatest facility, while-the escape of cold air when the dooris opened is prevented by the closure effected by the wing d and the closing piece 1) assuming the position shown in Fig. 4.

What I claim as new is- 1. In a refrigerator, a compound hinged door composed of two wings forming an angle with each other and a platform connecting the same at the bottom; combined with a closing piece co-operating with the inner wing to complete the closure of the door opening, and an operative connection between the door and said closing piece, substantially as described.

52. In a refrigerator, a compound hinged door composed of two wings forming an angle with each other and a platform connecting the same; combined with a hinged closing-piece co-operating with the inner wing to complete the closure of the door opening, and a sliding connection between said piece and the door, substantially as described.

3. In a refrigerator, a compound hinged door composed of two wings forming an angle with each other and a platform connecting the
