Abstract
152,234. Sargent, J. A. Dec. 1, 1919. Shade-holders.-An electric lamp shade-holder comprises a lamp-holder having an upper threaded portion and a lower portion with the grooves for the pins in the lamp head, embossed so as to project. A ring 3 is screwed on to the threaded portion, and the shade is then placed in position. A ring 9 formed with gaps 10 is then passed over the lower portion, the gaps 10 allowing it to pass over the projections 4, after which it is given a part turn until pins 11 enter into recesses 12. The ring 3 is then screwed down to clamp the shade in position.
