Corrugation 11 engages the threads of terminal 17 and maintains bulb 12 in position. The latter may be moved longitudinally by screwing it in the ordinary manner or by pushing it. As the bulb is pushed longitudinally, when a corrugation 11 passes a thread upon terminal 17, terminal lead 8 is depressed. When the adjacent groove upon terminal 17 is reached corrugation 1l moves into such groove with a snap. 'Io maintain the hand lamp in the inoperative posi-y tion terminal 16 of bulb 12 is maintained in spaced relation to terminal lead 9. To energize bulb 12,

terminals

16 and 9 are brought into contact with each other. To accomplish this, terminal lead 9 may be moved into contact with terminal 16 or bulb 12 may be moved into contact with terminal lead 9 by either the pushing be permitted to return to its normal position.

The movement of terminal lead 9 toward and away from bulb l2 may be used for flashing contact while movement of bulb 12 toward and away from terminal'lead 9 may be used for permanent or continuous contact. Y

Fig. 4 illustratesa different type of closure for the battery and support for arch 10. It is a preformed disc lof phenolic condensation compound or other plastic which is formed with the lugs 173 of arch 10 imbedded therein. With such construction the arch is alsol preferably constructed of hardened resinous or similar composition. The battery closure may be formed by pouring fusible sealing compound into the top portion of casing 1. Insuch case the bulb holder "may be held in positionduring the operationrof Y forming the closure and when the latter hardens the legs of the holder will be imbedded iirmly in the closure.

In the modication ofthe arch illustrated in Fig. 6 the ends of corrugation 11 are turned inwardly to form lugs 18. The length of lugs 18 may be varied to suit the conditionsand mate` rial used in making the arch. This type of arch is capable-of holding the incandescent bulb in positionabove the closure of the battery withoutthe aid of spring terminal 8. Lugs 18 maybe madev so that they do not lit bulb 12 tightly enough to prevent operation of the hand lampk by pushing bulb 12 back and forth.

A preferred form of the hand lamp is shown in Fig. 7. -In-this case the legs of Vthe bulb holder 20 are attached to a collar 21 instead of having lugs -at their ends engaging the closure disc of the battery. This collar is adapted to lit frictionally over the upper portion of the bat- -tery.- The entire holder preferably is stamped and shaped from a single piece of sheet metal.

The frictional engagement between the battery and collar 21 is sufficient to prevent theholder from becoming detached from the battery during normal use. When a metal carton is used as the battery container with this type of bulb holder, `care shouldy be taken that cell 3 is insulated from the container if only one cell is insulated therefrom as is statedto be possible in the mentioned application Serial No. 382,181. It is preferable to insulate both cells from the container to avoid all possibility of the bulb holder causing a short circuit. In the device shown in Fig. 7 the bulb holder, with or without the bulb mounted therein, may be sold separately.v
