Be it known that l, FREDERICK MsAnows, citizen ol the'United States, residing at Berkeley, in the countyof Alameda and State of California, have invented new and useful Improvements in Electric Flash-Light Attachments, of which the following is a specification.

My invention relates to devices andattachments for electric'fiash lights.

It consists in the combination of arts, and in details of construction which Will-be more fully explained by reference to the accomeru ise conveniently disposed. When a light" is to be'shown, the wearer of the device presses the spring arm '11 against the ring 12.

wire 9, the bolt 10*, the spring arm 11, the ring 12, the metallic shells, the bracket 3", I the insulated. filament 4 within the globe, the s ring 5, the metal plate Sand the wire 9. he light may thus bev produced at will by simply pressing the spring 11' against the ring 1-2 by the compression of the fingers, and the light \i-ill be cut off by releasing the the person of the operator, with connected spring 11. f means for completing an electrical circuit to This device isliespecially useful for those illuminate parts which are to be inspected or working in the dark,and needing to use both hands, since the ring being slipped upon the finger, the spring completing a circuit, may be readily pressed into contact with the ring, by closing the contiguous finger against it. The light will thus be directed ahead and both hands may be used to carry on the work. It is especially Valuable also for policemen who may need to identify persons, or to produce a light, when both hands arc occu pied as in the case of unruly prisonersyand it may be used for any purpose where it is convenient and necessary to thus support the light.

Having thus described my invention, what i l claim and desire'to secure by Letters Pat- Figure 1 is a perspective view illustrating the device'as inuse. Fig. 2 is a central longitudinal sectional View.
