Application February 13, 1933I Serial No. 256,153

' 3 Claims. (01. 173-328) This invention relates to improvements in lamp socket caps.

Broadly, it is an object of my invention to produce a lamp socket cap which will cover the 5 lamp socket and fit snugly and securely upon the lamp socket.

More particularly, it is an object of my invention to provide a lamp socket cap that will flt upon a lamp socket by frictional means so that 10 the end of the lamp socket will be covered by an ornamental cap and will aid in keeping the lamp within the socket.

Another object of my invention is to provide a lamp socket cap particularly for fluorescent lamp ll sockets, the cap to be maintained in position upon a lamp socket by frictional means which is invisi-.

ble when the cap is in position upon the socket.

Another object is to provide a lamp socket cap that can be economically manufactured, of neat an appearance and readily removed and replaced when desired.

For a fuller understanding of the nature and objects of my invention, reference is had to the following detailed description in connection with 5 the accompanying drawing, in which:

Fig. 1 is a plan view showing the inside of the lamp socket cap having a single teat projecting at right angles from said cap into a slot of a fluorescent lamp socket.

30 Fig. 2 is a plan view showing the inside of the lamp socket cap having a single teat projecting at an acute angle from said cap into a slot of a fluorescent lamp socket.

Fig. 3 is a plan view showing the inside of the 35 lamp socket cap having double parallel teats projecting at acute angles from said cap into parallel slots of a fluorescent lamp socket.

- Fig. 4 is a vertical section taken on line 44 of Fig. 5, showing the cap, part of-the socket and 40 part of the lamp.

Fig. 5 is an end elevation of the cap and part of the lamp socket showing the design and contour and revealing that various designs and ornamentation may be used.

)5 Fig. 6 is a side elevation of the cap seated upon the lamp socket, showing part of said socket and part of the fluorescent lamp.

Referring to Fig. 1 of the drawing, numeral I represents a fluorescent lamp socket with a single 50 vertical channel or slot H to receive the pin l2 of a fluorescent lamp l3, shown in Fig. 4.

The lamp socket cap 14 has a teat i projecting from flange l6 and base H. The flange l6 has an opening I! wide enough to permit entrance of 55 the lamp socket in within the cap chamber 40 to permit entrance of the socket 38.

formed by the base I! and the flange of the cap M. The teat I5 is placed opposite opening ll so that it will enter the channel ll of the socket ill. The teat I5 is of sufficient width and thickness so that it will enter channel H and be held 5 ing contact blades 22. 10

In placing the fluorescent lamp within socket in, pin l2 (shown in Fig. 4) passes througli socket channel II and central channel 2i so that pin l2 comes to rest against blades 22-. The cap 14 is then placed over socket l0 acting as a cap or 16 crown for the socket Hi and lamp l3.

In Fig. 2, there is a modified lamp socket 23, with a channel 24 placed at an angle. The cap 25 has a flange 26 at right angles to base 21. Flange 26 has an opening 28 to permit entrance of .the socket 23. A teat 29 projects from the flange 26 and base 21 at an acute angle and parallel to channel 24 of socket 23. The teat 23 I is opposite opening 28 and the width of channel 24 so that it will enter channel 24 and be firmly held in frictional engagement within said channel. Within channel 24 there is a moveable contact blade 30 for pin l2 of the fluorescent lamp In Fig. 3 there is another modified lamp socket 30 3| having twochannels 32 and 33 to receive the pins of a fluorescent lamp. Cap 34 is similar to cap 25 except that it has two projecting teats 35 and 36 instead of one. The teats 35 and 36 are parallel and project at acute angles from flange 35- 31 and run parallel to channels 32 and 33. Channels 32 and 33 have moveablecontact blades 38 and 33, respectively. Flange 31 has an opening Teats 35 and 36 are placed opposite opening 40 and are as 0 wide as channels 32 and 33 so that they are held by frictional engagement within said channels.

It is obvious that various changes and modifications may be made in the details of construction without departing from the general spirit of the 46 invention, as set forth in the appended claims.

I claim:

1. A lamp socket cap, comprising a base and a flange projecting from said base, an opening in said flange to receive a lamp socket, a teat de- 50 pending from said flange opposite said opening for'entrance into a slot of a socket and a space between said teat and said base.

2. A lamp socket cap, having. a base, a flange at right angles to said base and substantially surll rounding said base, an opening in said flange for receiving a lamp socket, teats projecting from said base and flange opposite said opening for entrance into lamp socket slots, and a space between said teats and said base.

3. In combination with a lamp socket, a cap having a base, a flange projecting from said base and disposed to one side thereof and at right angles thereto, an opening in said flange for entrance of said lamp socket, teats projecting from said flange opposite said opening, a space between said teats and said base, slots at the end of said lamp socket, said slots slightly larger in width than said teats and cooperating with said teats to 5 maintain said cap upon said lamp socket by trictional engagement.

FREDERICK K. MAERZ.
