ABSTRACT:
This invention relates to a battery powered lamp device which includes an upright base of metal, a bulb and switch-retaining member of metal and an upright chimney. The member has lower and upper ends and is mounted on the upper end of the base. The chimney is mounted on the upper end of the member. The base is provided with an upright elongated battery-receiving cavity closed at its bottom and open at its top. The aforesaid member is provided with a bore which is in registry with and constitutes an extension of the cavity. A bulb provided with a base having a central contact is mounted on said member and within the bore in such a manner that the illuminating portion of the bulb extends within the chimney. The base of the bulb is fitted into the upper portion of the bore for positioning the contact centrally thereof. A compression spring is disposed within the cavity in electrical contact with the bottom thereof. A battery within the cavity extends into the bore and at one end conductively engages the spring. The battery is further operatively engageable at the other end with the bulb contact. An electrical switch device on the member may be manually manipulated for moving the battery into and out of operative engagement with the bulb thereby to control the energization thereof.
