LAIYP LOCK,

Application tiled April 2,

T 0 all w hom t may concer/1t:

Be it known that I, RALPH E. S'roorrnn, a citizen Of the 'United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and u se ful Improvements in Lamp Locks, of which the following is a specification.

This invention relates to a lock for electric lamps such as are adapted to be supported within a bracket, and it is particularly suited for use with an electric light'designed to illuminate the face of a taxicab meter, the purpose being to prevent removal of the lamp and the consequent obscuration of the meter readings.

An exemplitication of this invention is illustrated in the accompanying drawing in the manner following: Figure 1 is a side elevation of a meter in operative association with a lamp which is equipped with the present lock; Fig. 2 is an elevation of the front side of the lamp, the view being such as would be gained by looking along the line 2-2 of Fig. l; and Fig. 3 is a side elevation of the bracket with the housing for the lamp shown in longitudinal section.

The lamp is shown as carried by a bracket A preferably secured to the forward side of the bulkhead B which is arranged just rearwardly of the chauifeurs seat in a taXicab, the lamp, designated as C, being adapted to throw its light upon the face of an adjacent meter D. It should be understood that the particular location of the lamp, as well as the manner of its attachment, is of no special importance to this invention.

The lamp is arranged within a generally cylindrical housing 5 having a lateral opening 6 in the form of a. slit which faces the meter, thereby permitting the light to shine thereon. This housing is preferably oii'set with respect to the bracket A on which it is carried so as to permit the lamp to move in and out of the housing by vertical movements without interference from the bracket, the housing being open at the bottom, as shown. In general the lamp socket may follow the usual construction, its component parts including an insulating bushing 7 around which is secured a sleeve 8 having the usual bayonet slot 9 for the reception of a pin l0 which projects laterally from the lamp neck 11. Attached to the lower end of the bushing is a cap 12 having an outwardly extending flange 13 in which are 1921. serial No. 58,07% l formed a plurality of liolesilll, the lower end of the cap being open to permit the circuit wires 15 to ypass therethrough toA connect with a current source. Secured fastl to the sleeve which surrounds the bushing is a collar 15a having a lateral opening 16 into which may project the end of a set screw 17 that is adapted to thread into an opening 18 which extends through the wall of the housing adjacent its base. The lower end of the collar is outturned in the form of a flange 28 which abuts against the base of the housing to limit the entry of the lamp there within to the correct distance.

Formed in the head 19 of the set screw is a transverse opening 2O permitting a wire 21 to be passed therethrough as well as through one of the openings lli in the cap flange,`the ends of the wfire` being then brought together and fastened with a seal 22.

The construction just described suggests,

as a means for locking the lamp in a fixed position within the housing, the use of a set screw together with certain other parts. The wire with its sealed ends in this construction serves to prevent the screw from being loosened preliminary to a withdrawal of the lamp. Only by breaking the seal of the wire may this be accomplished, and this, of course, would be readily apparent to those whose duty it is to inspect the auto mobile from time to time. l

It will be observed that the parts which constitute my invention are not only simple t:

in their construction and assembly, but they are durable and effective for the purposes contemplated. There are other forms in which this invention might be embodied, and in so far as the same are defined in the claims below, I would have such modification included within the scope of this patent.

I claim:

l. A `device o-f the kind described comprising, in combination,v a housing open at one end and formed with a threaded opening in one side, a lamp adapted to lie within the housing, a socket adapted to receive the lamp, a collar surrounding the socket and provided on one side with an aperture and at one end with an outturned flange arranged to abut the proximate end of the housing to limit the entry of the lamp therein, a cap secured` to the socket provided gaged by the Wire, substantially as described.

2. A device of the kind described comprising, in combination, a housing one end of which is open and formed with a threaded aperture in its Wall, a lamp adapted to stop for limiting thexentry of the vlamp Within the housing, a threaded `element ar- 7 be moved through the opening into the housing, a socket to which the lamp is connected, means on the socket providing a ranged Within the aperture in engagement With the socket vand adapted to prevent its removal from the housing, and means connecting the threaded element with the socket havingv a seal associated therewith for preventing disengagement of the threaded element with the socket except when the seal is broken, substantially as described.
