Abstract

Abstract A wrist watch has a glass fitted in a snap. An inwardly facing groove in the snap, normally closed by the glass, houses a miniature bulb connected by wires passing through watertightlyclosed openings communicating the snap with the outside of the watch case. The wires are connected to batteries housed in extensions to the watch case, said extensions including a switch to enable illumination of the bulb by a pressure on the wearer''s wrist.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 200 words
A wrist watch with dial-illuminating means, comprising a case, two diametrically opposed hollow lugs pivotally mounted on the case, means on the lugs for fixing a watch bracelet, a housing in each lug for an electrical battery enclosed in a mass of plastic material forming a surface for contacting a wrist on which the watch may be worn, one of said mass including a switch actuatable by pressure against said wrist, two insulated conducting wires each provided with a contact plug for connection with a pole of the corresponding battery, means for connecting the other pole of each battery to ground, a snap in the case, a glass held in the snap, an inwardly facing groove in the snap, said groove normally being closed by the glass, two openings each for the passageway of one of said wires connecting said groove to the outside of the case, means for fluidtightly closing said passageways, a mercury contact breaker housed in one of said masses of plastic material and connected between a pole of the battery in said one mass and the corresponding wire, and a miniature electric bulb housed in the groove, said two wires connecting the bulb to the batteries.
Claim 2
Dependent Claim 200 words
A wrist watch with dial-illuminating means, comprising a case, two diametrically opposed hollow lugs pivotally mounted on the case, means on the lugs for fixing a watch bracelet, a housing in each lug for an electrical battery enclosed in a mass of plastic material forming a surface for contacting a wrist on which the watch may be worn, one of said mass including a switch actuatable by pressure against said wrist, two insulated conducting wires each provided with a contact plug for connection with a pole of the corresponding battery, means for connecting the other pole of each battery to ground, a snap in the case, a glass held in the snap, an inwardly facing groove in the snap, said groove normally being closed by the glass, two openings each for the passageway of one of said wires connecting said groove to the outside of the case, means for fluidtightly closing said passageways, a mercury contact breaker housed in one of said masses of plastic material and connected between a pole of the battery in said one mass and the corresponding wire, and a miniature electric bulb housed in the groove, said two wires connecting the bulb to the batteries.
Claim 3
Dependent Claim 27 words
A wrist watch as claimed in claim 1, in which said first and second springs and contacts are respectively housed in mobile third and fourth insulating blocks.
Claim 4
Dependent Claim 300 words
A wrist watch with dial-illuminating means, comprising a case, two diametrally opposed hollow lugs pivotally mounted on the case, means on the lugs for fixing a watch bracelet, a housing in each lug for an electrical battery enclosed in a mass of plastic material forming a surface for contacting a wrist on which the watch may be worn, one of said masses including a switch actuatable by pressure against said wrist, two insulated conducting wires each provided with a contact plug for connection with a pole of the corresponding battery, means for connecting the other pole of each battery to ground, a snap in the case, a glass held in the snap, an inwardly facing groove in the snap, said groove normally being closed by the glass, two openings each for the passageway of one of said wires connecting said groove to the outside of the case, said openings being diametrally opposed and terminating outside said case in the vicinity of said extensions, means for fluidtightly closing said passageways, and a miniature electric bulb housed in the groove, said bulb having first and second ends, the first end of the bulb being located near one of the openings, said two wires connecting the bulb to the batteries, one of said wires passing through said one opening and being connected to the first end of the bulb, and the other wire passing through the other opening, passing around said groove, and being connected to the second end of the bulb, said wires being supported in said groove on first and second insulating blocks, a contact on the first end of the bulb being connected to one wire by a first spring, and a contact on the second end of the bulb being connected to the other wire by a second spring.
Claim 5
Dependent Claim 300 words
