' ELECTRIC SOCKET AND SHADE FIXTURE Filed Feb. 18, 1955 A? INVENTOR Isaac Lilner ATTORNEY Patented Nov. 12, 1935 UNITED STATES PATENT OFFICE Isaac Litner, Brooklyn, N. Y., assignor to Bright Light Reflector Co. Inc.,. Brooklyn, N. Y.

Application February 18, 1935, Serial No. 7,011

4 Claims.

This invention relates to a combination electric socket and shade fixture, particularly of the type adapted for rotatably supporting a lamp shade,- one of the objects of my invention being to permit a quick asembly of the socket and shade, and another to enable a rotary manipulation of the shade without impairment to the socket.

After a lamp socket is secured in place to a fixture support, upon the completion of the wiring thereof, it is frequently a problem to conveniently position thereover a shade without the necessity of detaching the socket or performing some time-consuming or relatively complicated assembling operation; and it is hence to solve this problem that I have conceived thisinvention, whereby just such an easy assembling operation can be efiected, at the same time permitting the shade, acting as-an angle reflector, to be rotatably manipulated through an angle It is still another object of my invention to protect a socket, particularly of the porcelain variety having thereon oppositely positioned perforated ears, from breaking especially during the rotary manipulation of the shade.

Other objects, features and advantages will appear from the drawing and the description hereinafter given.

Referring to the drawing,

Figure 1 is a side view of the device containing my invention, the socket being concealed within the shade.

Figure 2 is an enlarged vertical fragmentary section of the assembly of Figure 1, part of the flange of the socket being shown broken away.

Figure 3 is a vertical transverse section of Figure 2 taken along line 3-3.

Figure 4 is a bottom sectional view of Figure 3 taken along line 4-4.

Figure 5 is a fragmentary perspective view of the lamp shade showing the opening in the base thereof with two stops thereon adapted for coaction with the guard around the socket, and

Figure 6 is a fragmentary perspective view of 4.5 the socket, showing the protecting guard embracing the flanged portion thereof.

In the drawing the socket [0, which may be a porcelain unit, contains thereon the annular flanged portion H having the oppositely posi- 50 tioned, outwardly extending perforated ears I2 and I3, the holes in the-said ears being adapted to receive the screws I4 and I5 which are in threaded engagement with the bottom flanged portion 31 of the circular guard or band l6 em- 55 bracing the lateral surface and undersides of the flange II and its said ears. The upper outer peripheral edge I! of the flange H is preferably bevelled off to substantially the upper peripheral edge of the guard, although only that portion of said edge at the ears l2 and I3 need be so bevelled 5 for the purposes of this invention.

The socket i3 is attached to the fixture I8, generally made of metal, by means of the two screws [9 and 23 which extend through suitable openings in the body of the socket into the 10 tapped holes 2| and 22, respectively, of the said fixture. The upper threaded terminal portions of said screws are of enlarged diameters, and the

washers

23 and 24 are mounted over the shanks of the screws below said enlarged termi- 15 nal portions thereof to prevent the screws from dropping out when they are not in threaded engagement with the fixture. Interposed between the heads of the screws and the corresponding seats therefor within the

recesses

25 and 26 of 20 the body portion of the socket are the

helical springs

21 and 28, preferably of conical shape to permit a greater movement of the screws during compression.

The shade 29 has a flanged base 30 thereon 25 containing a central opening communicating with the recesses 3| and 32 which are sufficiently wide to clear the said ears l2 and 13 when the shade. is being assembled in its operative position. The said flanged base 30 also contains, 30 preferably integral therewith, the downwardly extending prongs or stops 33 and 34, which, as will hereinafter be explained, serve to limit the rotary movement, and hence the ultimate position of the shade. 35

After suitable lead wires are extended through the opening 35 in the support l8 and operatively attached to the terminals of the socket I0 in the usual way, said socket is afl'ixed to the support It by manipulating the

screws

13 and 20. The 40 shade 29 is then placed in its operative position by inserting it over the socket so that the recesses 3| and 32 clear the ears [2 and i3 and the flanged base 30 is superimposed and rests upon the top surface of the socket. The shade is then rotated until the stops 33 and 34 come into engagement with the armoured sides of the said cars,at which point the, shade is. at one of its extreme positions, such as is shown in Figure 4. Where an angle reflector is employed, such as is shown in Figure 1, and it is desired to have it positioned at an angle of 180 from that shown in Figure 4, the reflector (or shade) is simply inserted at 180 from the other position and rotated in the opposite directi0n,thereby permit- Inasmuch as the said stops 33 and 34 extend downwardly, and not inwardly in a radial direction into the central opening in the base of the shade, they do not constitute obstructing elements,-thereby permitting the ready insertion of the shade in place. 7

It will be noted that the abutments for said stops are the oppositely positioned ears I21 and I3 which, inasmuch as they are generally constructed of porcelain, might readily be subject to breakage due to the impact of said stops during the rotary manipulation of the shade. In order to prevent such an occurrence the annular band or guard I 6 is employed, this'consisting preferably of a laterally enclosed open-ended band of metal shaped to conform with the flanged portion of the socket and the ears thereof, the bottom of the guard containing a flanged portion 31 adapted to underlie the flange and ears and receive the said screws I4 and I5 for securing it in place. This guard not only protects the flange II, and particularly the ears l2 and I3, thereof from the impact of the stops 33 and 34, but also serves as a retaining member to hold together any broken portions of said cars which may become cracked due to the manipulation of the screws l4 and I? or other reasons.

In other words, even if one of said ears should break, no broken portion thereof can become detached due to the fact that it will be retained in place by the walls of said guard. As previously stated, it

is desirable to bevel off the upper edges of the flange Ii, particularly above at the ears thereof, up to or near the upper edge of the guard, so as to prevent any exposed portion of the flange from breaking off.

The attaching means employed for securing the socket E0 to the fixture l8 enables a ready and firm attachment to be effected, and yet provides a yieldable method, by the use of the

springs

21 and 28, of compensating for irregularities in. the thickness of the top flanged base 30 of the shade. Inasmuch as the pressure of these springs is directed against the body of the socket, it will be yieldably yet firmly held clamped against the fixture It. It should further be noted that the socket is directly attached to the fixture 8 without the use of any intermediary plates or other elements,the only units being the assembly of socket and screws, the shade 29 and thefixture l8.

It will also be seen that the shade can readily be detached, without manipulating any screws or other attaching elements, and without affecting the assembly of socket and fixture.

It is of course understood that the structure above described and shown in the drawing is illustrative of my invention and not employed by way of limitation, inasmuch as numerous changes and modifications may be made within the scope of the appended claims without departing from the spirit of this invention.
