Abstract
Abstract A flashlight in accordance with the preferred embodiment of the invention includes a housing enclosing an insulating battery retaining member formed with spring arms for retaining a pair of batteries in spaced-apart relationship. Further included is a light bulb having a pair of leads extending therefrom and carried at one end of the housing with the leads each connected to a battery. Adjacent the opposite end of the housing a conductive switch member is frictionally retained on the positive post of one battery and extends between the battery retaining member and a flexible wall of the housing. The other end of the switch member is located adjacent a cutout portion of the battery retaining member which exposes a conductive surface of the other of the batteries so that when the flexible wall of the housing is pressed the other end of the switch wire contacts the other of the batteries completing a circuit between the batteries and the light bulb. Stop members are formed on the battery retaining member and retain the batteries against axial movement.

Claim 1
Independent Claim
300 words
A flashlight comprising a housing having a generally flexible side wall, a first end wall and a second end wall having a central opening therein; an insulating battery retaining member including resilient arm members retaining a pair of batteries having exposed conductive surfaces, one end of one of said batteries projecting beyond the end of said battery retaining member adjacent said second end wall with its positive post extending beyond the end of said battery retaining member adjacent said first end wall, one end of the other of said batteries projecting beyond the end of the battery retaining member adjacent the first end wall with the positive post thereof projecting beyond the end of said battery retaining member adjacent said first end wall whereby, the positive post of said one battery and the end of said other battery bear on said first end wall; a light bulb at the end of said housing adjacent said second end wall with a portion of said light bulb extending through said central opening, said light bulb being electrically connected to said batteries; a pair of stop members formed on said battery retaining member at the end thereof adjacent said second end wall, each stop member bearing on the end of a battery member for preventing movement of said battery members toward said second end wall; and a conductive switch member frictionally retained on said positive post of said one of said batteries, said switch member including a portion extending between said flexible side wall and said battery retaining member and terminating adjacent a cutout portion of said battery retaining member exposing a conductive portion of the other of said batteries whereby said switch member completes a circuit between said batteries and said light bulb when force is applied to the flexible side wall.
Claim 2
Dependent Claim
300 words
A flashlight comprising a housing having a generally flexible side wall, a first end wall and a second end wall having a central opening therein; an insulating battery retaining member including resilient arm members retaining a pair of batteries having exposed conductive surfaces, one end of one of said batteries projecting beyond the end of said battery retaining member adjacent said second end wall with its positive post extending beyond the end of said battery retaining member adjacent said first end wall, one end of the other of said batteries projecting beyond the end of the battery retaining member adjacent the first end wall with the positive post thereof projecting beyond the end of said battery retaining member adjacent said first end wall whereby, the positive post of said one battery and the end of said other battery bear on said first end wall; a light bulb at the end of said housing adjacent said second end wall with a portion of said light bulb extending through said central opening, said light bulb being electrically connected to said batteries; a pair of stop members formed on said battery retaining member at the end thereof adjacent said second end wall, each stop member bearing on the end of a battery member for preventing movement of said battery members toward said second end wall; and a conductive switch member frictionally retained on said positive post of said one of said batteries, said switch member including a portion extending between said flexible side wall and said battery retaining member and terminating adjacent a cutout portion of said battery retaining member exposing a conductive portion of the other of said batteries whereby said switch member completes a circuit between said batteries and said light bulb when force is applied to the flexible side wall.
Claim 3
Dependent Claim
43 words
A flashlight in accordance with claim 1 wherein said switch member comprises a flat elongated member bent adjacent one end to include a short leg portion having an aperture therein, which frictionally fits over said positive post of said one of said batteries.
Claim 4
Dependent Claim
35 words
A flashlight in accordance with claim 2 wherein a cylindrical sleeve member extends from said short leg portion around said aperture toward said one of said batteries, said cylindrical sleeve fitting around said positive post.
Claim 5
Dependent Claim
34 words
A flashlight in accordance with claim 2 wherein said portion of said switch member comprises a long leg portion terminating in a tongue extending toward said conductive portion of the other of said batteries.
Claim 6
Dependent Claim
46 words
A flashlight in accordance with claim 1 wherein one of said stop members includes a first leg portion extending outwardly of said retaining member and a second leg portion extending between said arm members and bearing on the end wall of said one of said batteries.
Claim 7
Dependent Claim
39 words
A flashlight in accordance with claim 5 wherein said other of said stop members includes a single leg portion extending between said arm members and bearing on the end of the side wall of said other of said batteries.
Claim 8
Dependent Claim
56 words
A flashlight in accordance with claim 6 wherein said second leg portion extends from said first leg portion at a point spaced from the end of said battery retaining member a distance approximately equal to the distance between the end of said battery retaining member and the end of the positive post of said one battery.
