REFRIGERATOR.

Specification of Letters Patent.

Patented Sept. 8, 1908.

Application filed May 23, 1907. Serial No. 375,192.

To all whom it may concern:

Be it known that I, JosEPH OVILA LA MADELEINE, a subject of the King of Great Britain, residing at the city and district of Montreal, in the Province of Quebec, Canada, have invented certain new and useful Im provements in Refrigerators and I do hereby declare that the following is 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.

My invention relates to refrigerators, espe eially of that class adapted for domestic uses.

One object of my invention is to provide an alarm, and means for actuating the same when the water from the melted ice should be decanted to prevent overflow, which alarm is entirely within the casing, but which is readily accessible from the outside thereof, without deranging any of the other parts of the construction.

My invention consists of the construction, combination and arrangement of parts, as herein illustrated, described and claimed.

In the accompanying drawings, forming part of this application, I have illustrated one form of embodiment of my invention, in which drawings similar reference characters designate corresponding parts, and in which:

Figure 1 is a vertical section of a refrigerator showing the application of the invention. Fig. 2 is a fragmentary section through the lower part of the battery box only, taken approximately on the line 44.- of Fig. 1, and showing the movable contact in detail.

Referring to the drawings, 1 designates a casing, which may be of any approved form or construction.

Disposed in the upper portion of the casing 1, is an ice receptacle 5, provided with a screen drain tube 6. Disposed beneath the drain tube 6 is a water receptacle 7, which extends entirely across the rear side of the casing 1, and to a point adjacent the bottom thereof. A float 8 is disposed at any desired point in the water receptacle 7, and is connected with a pair of levers 9 through the medium of the links 10, which levers are supported on standards 1 1 secured at convenient points on the receptacle. One of the levers 9 is adapted to bear on a spring contact piece 12, which has one end secured by a binding post 13, and has its free end disposed adj acent to and adapted to contact with a binding post 14, which binding posts are electrically separated, except for the contact piece, and which binding posts are placed in a normally open circuit, including a battery 15 and a bell 16. The battery and bell are preferably placed within a casing 17 at the upper,

end of the casing 1. When the water rises to a predetermined height in the casing 7, the float 8 will be raised, and will cause a consequent movement 01" the upper lever 9 against the spring contact 12, causing it to close the circuit between the binding posts 13 and 14, and in that way the circuit is closed and the alarm given.

The casing 17 keeps the battery and bell dry, and the wall of the casing 1 adjacent the battery is provided with an opening 18, which is normally closed by a screen door 19. By this construction, ready access to the alarm mechanism is permitted without having to open the casing 1, thus preventing the escape of the cold air.

Having thus fully described my invention, 4
