This invention relates to flashlights employing a propelrepel carrier assembly of the swivel type. This application is a continuation-in-part of my co-pendin-g application Serial No. 318,679, filed November 4, 1952, now Patent No. 2,797,309, and which latter application was copending with my application Serial No. 50,999, filed September 24, 1948 and now Letters Patent No. 2,695,028, granted November 23, 1954.

United States Patent 9 The general object of the present invention is to prov vide a swivel type flashlightwithsafety means. for safeguarding against accidental lighting or darkening of the light bulb.

Specifically, it is the object of the present invention to provide a swivel type flashlight with safety means, generally employed in the lipstick container field to safeguard against lipstick smudging against the inner surface of a removable cover cap, to safeguard against accidental lighting or darkening of the light, bulb.

Other objects and advantagesof thepresent invention will be readily apparent in the course of the following detailed description taken in connection with the accompanying drawing which illustrates, by way of example, preferred embodiments of the invention and wherein- Fig. 1 is a longitudinal sectional and exploded view of the propel-repel carrier assembly removed from the outer casing, the bulb at one endof the outer casing being shown partly exposed, the internal elements, in the outer casing not being shown. V

Fig. 2 is a longitudinal sectional and exploded view of the flashlight illustrating the internal structure and arrangement of the component elements and, further, showing a plurality of firm elongated ribs spaced about the operating handle frictionally engaging a removable cover cap.

modified construction and showing a plurality of firm elongated ribs spaced about the casing frictionally engaging a removable cover cap which surrounds the operating handle. V

Fig. 3 is a longitudinal sectional and exploded view of a v Referring now to the drawing in detail andparticularly to Fig. 1, numeral 10 represents an inner tubular member having an elongated slot 11 and having an operating handle 12 exposed pastthe lower end of'the metallic spiralsleeve member 13. The broken lines, at the bottom of the handle portion shown, are to indicate that the bottom of the operating handle may be open or closed. The spiral sleeve member is loosely fitted on the inner tubular member and is provided with a helical slot 14. The annular rim 15 of theoperating handle and the annular bead 16 at the upper end of the inner tubular member limit the longitudinal movement of the spiral sleeve member. Metallic carrier cup 17 is positioned in the inner tubular member. The carrier cup is provided with a metallic lateral follower pin 18 which is positioned in slot 11 and in slot '14 so that rotation of the inner tubular member relative to the spiral sleeve member will cause the carrier cup to move longitudinally in the assembly.

A battery 19, indicatedby the separated dash lines, is positioned in the carrier cup, thepositive pole 20 being faced upwardly. In'the metallicouter casing 21 there is ice mounted a light bulb 22 shown, partly exposed in the upper end of the outer casing. The light bulb is electrically connected to the outer casing so that upon contact of the battery with the conductor (not shown) of the light bulb and the outer casing the electric circuit will be closed and the bulb will be lighted. The means for electrically connecting the light bulb to the outer casing has not been described at more length because it is believed that persons skilled in the art to which this invention relates fully understand the construction and will be more concerned with the means for closing the electric circuit by employing a longitudinally movable carrier. The outer casing is of sufficient lengthto snugly telescope over the spiral sleeve member'so that the outer casing and the spiral sleeve member may be rotated as a single unit relative to the inner tubular member to longitudinally move the carrier cup holding the battery, It is, therefore, evident that rotation of the operating handle relative to the outer casing will advance the battery and light the bulb.

Referring now particularly to Fig. 2, an'din accordance with the present invention, there is shown a plurality of firm elongated ribs A spaced about the operating handle 12'. Cover cap B is removably frictionally engaged: on the ribs A and the. interior of cover cap B is in spaced relation to the exterior of outer casing 21 so as to be out of engagement therewith. The positive pole 20', of the battery 19', is in contact with the conductor 24 of the light bulb 22' and the negative part 25, of the battery 19, is in contact with the reducedneck'portion 23., of the metallic outer casing 21', thus the light bulb, which is electrically connected to the outer casing 21', is lighted. In its assembled position on the ribs,-the cover cap-safeguards the flashlight against accidental darkening of the light bulb because it safeguards against accidental relative rotation of the operating handle and the outer casing. The cover cap is provided with an opening C through which the light, from the lighted bulb, passes. It willbe evident that when the positive pole 20, of the battery 19',

is not in contact with the conductor 24, of the light bulb,

i.e. is longitudinally spaced from the light bulb, the light bulb will be darkened and the cover cap, in assembled position, will safeguard against accidental lighting ofthe light bulb by safeguarding against accidental advance ment of the positive pole 20 toward the light bulb.

Referring now particularly to Fig. '3, there is shown a modified form of the invention. A plurality. of firmelonlgated ribs D are spaced about the metallicouter casing 21". Cover cap B is removably frictionally engaged. on the ribs D and the interior of cover cap B'.is in spaced relation to the exterior of the operating handle 12". In its assembled position, the cover cap safeguards against accidental relative rotation of the operating handle and the outer casing and thereby safeguards againstaccidental darkening of the lighted bulb and may be employedas a i handle for the flashlight.
