REFRIG ERATO R.

SPECIFICATION forming part of Letters Patent N 0. 728,017, dated May 12, 1903.

Application filed January 12, 1903. Serial No. 138,696- (No model.)

To all whom it may concern:

Be it known that I, JOHN ROSSI, a citizen of the United States, residing at Joliet, in the county of' Will and State of Illinois, have invented a new and useful Improvement in Refrigerators, of which the following is a specification.

My invention relates particularly to lighting means for refrigerators and other chambers; and my primary object is to provide means whereby the operation of unlatching the door of the chamberserves to close an electric circuit and light a lamp Within the chambers.

The invention is illustrated in the accompanying drawings, in which- Figure 1 represents a vertical sectional view of a refrigerator equipped with'my improvement, the door of the refrigerator being closed and the light-circuit broken; Fig. 2, a broken sectional view of the same character, but showing the door open and the light-circuit closed; Fig. 3, an enlarged broken View showing a portion of the outside of the refrigerator, and Fig. 4 a horizontal sectional view taken as indicated at line 4: of Fig. 3.

In the preferred construction, A represents a cooling-chamber provided with a door A; B, a door-securing lever fixed upon the outer end of a bolt a, passing through a portion of the wall of the chamber A adjacent to the free edge of the door; B, aswitch havinginsulated connection with the inner end of the bolt 0, and operated through the medium of said bolt; B a keeper for the free end of the hand-lever B, and 0 an electric light having a circuit 0', including the switch B, and supplied from an electric source 0 From the description given it will be understood that in the operation of lifting the hand-lever B to unfasten thedoor the switch B is operated to close the lamp-circuit, thereby lighting the lamp, and that the operation of lowering the member B to secure the door breaks the lamp-circuit. It will be understood that any suitable electric source may be employed for energizing-the lamp.

Minor changes in details ofconstruction within the spirit of my invention may be made. Hence no undue limitations should be understood from the foregoing detailed description.

What I regard as new, and desire to secure by Letters Patent, isn The combination of a chamber equipped at its inner side with an electric light and provided with a suitable door, a door-securing lover, a. keeper therefor afiixed to the outer side of the door, a pivot journaled in the door-frame and having said lever fixedly secured to its outer end, an arm fixed to the inner end of said pivot and bearing a contactpoint insulated from said pivot, an electric circuit having a conductor connected with said contact-point, and a fixed contact adjacent to the door-opening in the path of said first-named contact and connected with a conductor of said circuit, substantially as and for the purpose set forth.
