' BULB SOCKET LOCK AND THE LIKE Filed. Feb." 28, 1933 Patented May 15, 1934 UNITED STATES PATENT) OFFICE 2 Claims.

My invention relates to electric incandescent lamp socket locks, and more particularly to devices which are especially adaptable for locking the electric lamp base in place, within the socket, and thus preventing said lamp from becoming loose, or taken out therefrom, accidentally or otherwise.

It accordingly is an object of my invention to provide the electric lamp socket with means, preferably of resilient structure, such as spring or the like, which may be attached to the said socket in any manner most preferable in practice so as to provide a permanent means for locking the lamp base in place.

Another object of my invention is to provide the said electric lamp base with the lock'locating means, which may be indented thereon or attached thereto, and positioned in such a manner whereby said base may be placed or screwed into the socket and held therein by means of the said locking device positioned upon or connected to the said socket and made a .part thereof.

A further object of my invention is to provide said socket with the locking means made substantially a part or out of the same material the lamp socket is made out of, having the base provided with indentation and thereby providing the locking as well as the contact means for said base within said socket, thus preventing the removal of said lamp from said socket, unless the said lamp is rendered entirely useless.

Further objects and advantages of my invention as will hereinafter more fully appear, I attain by the construction herein described and illustrated on the drawing forming a part of my application.

Reference is had to the accompanying drawing in which the similar reference characters denote the similar parts. 4

In the drawing;

Fig. 1 is the elevational view of the electric glass bulb, positioned within the socket.

Fig. 2 is the transverse cross-sectional view of the socket. taken on the line 22, of the Fig. 1. I

V Fig. 3 shows the enlarged fragmentary crosssectional view of the locking device, taken on the line 3-3, of the Fig. 2.

Fig. 4 shows the perspective view of the locking device upon the socket and the indentation upon the lamp base.

Fig. 5 shows the enlarged cross-sectional view of the locking device, in modified form.

Fig. 6 shows the locking spring, in modified form.

Describing my invention more in detail, said invention comprises an electric lamp socket holder, generally designated by numeral 2, having a lamp base 4, attached to the glass bulb 6.

The said lamp socket holder 2, comprises a shell 8 which is spirally corrugated as at 10, having a sub-base 12 and the outside rim section 14, which is adapted to receive the said lamp base 4, as shown.

The shell 8, is provided with an opening 16, which may be of any desired shape, preferably rectangular as at 18, having the locking member 20 such as for an instance a spring, which may be attached to the said sub-base 12 by means of a screw 22, or a plurality of rivets 24, (see Figs. 3 and 6) or, said locking member 20 may be made a part of the said shell 8, as shown in Fig. 4 which is adapted to hold the said lamp base 4 in place by means of the tension of the said locking member 20, against the said lamp base 4.

For the purpose of locking the said lamp base 4 within the shell 8 I have provided an indentation 26, which may be at any point upon the surso face thereof, preferably however, in form as shown in Fig. 2 which is tapered as at 28, having a wall provided as at 30 so as to allow the said lamp base 4, to be turned Within said shell 8 in a direction accomplishing a contact of the said lamp base with the said socket, as previously described.

In the Fig. 5 I have shown the rotary locking finger 32 in modified form, comprising a socket member 34 having said locking finger 32 pivoted as at 36 and having an extension 38 attached thereto, so that when in operation, the said locking finger is forced into said indentation 26 of the said lamp base 4, by means of the said extension 38 which bears against the glass bulb 6.

In the Fig. 6 I have shown the locking member 40 in another modified form, having the base strip 42 wider in proportion than the'strip itself, thus allowing said base strip to be held substantially in place by means of a plurality of rivets or screws, as previously described, so as to prevent the side thrust of the locking member within said socket.

It is obvious to note that the said locking memher will be held in place regardless of the amount of rivets or screws are being used to hold the same in place, because of the fact that the opening 16 will not permit said locking member from being twisted sidewise, and in the event it is desirous of extracting said glass bulb 6 from the said socket holder 2, the user or the operator may pry the said locking member upwardly and away from the indentation by means of a blade or other instrument, thus'permitting the glass bulb lamp base to be unscrewed from the said socket.

While I have thus described my invention with great particularity it will be clear that the same may be modified throughout a wide range. I accordingly do not propose to be limited to the exact details of construction herein shown and described, but reserve the right in practice to make any and all modifications and changes which may come within the scope of the appended claims.

I claim as my invention;

1. In the devices of the class described the combination of a socket member, a spirally corrugated shell member and a glass bulb lamp having a spirally corrugated lamp base engaging said shell member, an opening positioned upon the rim section of said shell member, an indentation positioned upon the surface of said corrugated lamp base, a locking finger having an extension pivotally connected to said socket member, protruding through said rim section of said shell member to engage the indentation of the said lamp base and the extension engaging the glass bulb of said lamp, so that the said lamp base may be held and locked in place and prevented from being removed from the said socket member.

2. In the locking devices of the class described the combination of an electric glass bulb socket holder having, a spirally corrugated shell positioned within said holder, and a lamp base a permanent part of the said electric glass bulb, engaging said shell within said holder, an indentation positioned upon the surface of the said lamp base and a rotary locking finger pivotally connected to said socket holder engaging the said indentation of said lamp base, so that the said glass bulb may be locked in place within the said socket holder.
