MEANS FOR MOUNTING LAMP SHADES ON LAMP HARPS Filed July 20, 1950 INVENTOR. HERBERT LAGI N BY W ATTORNEY Patented Nov. 10, 1953 UNITED STATES PATENT OFFICE MEANS FOR MOUNTING LAMP SHADES LAMP HARPS The present invention relates to a means for mounting a lampshade on the harp frame of a lamp.

In order to mount the shade on the wire frame of a lamp to cover the light thereof, frames re-' ferred to in the art as a harp were secured to the base of the lamp extending upwardly therefrom around the light and on which harp a shade was mounted.

It became desirable to tilt the lamp shade at an angle to a plane passing vertically through the light bulb of the lamp so that light therefrom could be selectivelydirected to different portions of the surface on which the lamp rested.

Swivel connections were designed for securing a lampshade on the harp frame, so that such operation of tilting could be performed.

Swivel connections heretofore proposed for this purpose were comparatively complex in structure and not simple for mounting on the harp of the lamp shade.

The present invention therefore contemplates the provision of a connection by means of which a lamp shade may be mounted on a lamp harp for swinging thereon into a selected position and which connectionor mounting means is relatively simple and inexpensive to manufacture and which may be comparatively easily mounted on a harp frame.

The present invention still further contem- Claims. (Cl. 240-148) plates the provision of such a connection so arranged'and constructed that the lamp shade will not inadvertently be rotated around a vertical axis through the harp frame,a disadvantage inherent with all constructions heretofore pro- I posed.

In lamp shades heretofore provided, the wire frame included a spiderat the top thereof which was permanently secured on the upper wire member of the frame.

The present invention therefore contemplates the provision of a spider, which is detachably mounted on the upper wire of the lamp shade Fig. 3 is a perspective view of the other member or washer of the connection;

Fig. 4' is a partial cross section to an enlarged scale of my connection mounted on the cross wire of a harp frame;

Fig. 4A is a'partial perspective of a harp frame cross wire used with an embodiment of my invention;

Fig. 5 is a perspective view of a modification'of one of the members of my connection;

Fig. 6 is a top plan view of a lamp shade and spider frame member according to my invention;

Fig. '7 is a section on the line of Fig. 6;

Fig. 8 is a partial section of a modification thereof.

Referring now to the drawing, the lamp base H has mounted thereon a conventional harp frame l2, which may be in the shape illustrated and on which the lamp shade I0 is seated by means-of the connection which is the subject matter of this application.

The connection comprises two members, one of which [4 is illustrated in Fig.2 and the other of which, the washer I6, is illustrated in Fig; 3.

Extending up from the body I5 of the member I4 is provided the'screw or threaded stud element I8 and extending outwardly from the sides of the body [4, I provide the fingers 20 and 22.

Extending up fromthe undersurface ofthe bodyil5,'I provide the recess 24- in whichis received the teat 26 on the crosswire 28 (see Fig; 4)

of the harp frame I2, for the purpose of which I shall hereinbelow describe.

I'n' assembling the lamp shade NJ on the harp frame E2, the member I4 is placed on the cross wire 23 with the teat 26 seated in the recess 24 and the fingers 20 and 22 bent around the cross wire 28along the arrows 21 and 29 to hold the member thereon. I

The washer 16, from the sides of which extend the four spider arms 30, which, as will be seen, are mounted on the upper wire '32 of the frame of the lamp shade it, is then seated in place on the member [4.

The washer I6 is provided through the center thereof withthe'opening'34 through which the threaded stud element l8 extends and on which stud element [8, the finial 36 is mounted to lock the lamp shade in place on the harp frame I2. The sides of the washer [6 are cut out to form the side channels 38 and 40 through which the cross wire 28 extends.

Thus, the connection just describedmay be rotated'in selected position on the cross wire 28 i to tilt the lamp shade Ill into any desired posithe teats 42 and 44 may be omitted and only a single teat 26 provided (Fig. and, a ltl ough even the teat 26, if desired, may also be omitted;

It will now be recognized that the connection may be rotated about the cross wire 2-8 thereonto selectively tilt the lamp shade ill to direct li ht from the lamp 48 to desired parts of the surface on which the lamp is supported.

If desired, instead of the member (4 in which the fingers Z and 322 are hentr'af-ter @thezmem'ber is placed on the cross wire 2B,;arpreformedthread: ed :stuidrelement dill itsee Fig.5) having the curved fingers 1:52 -and:;54 may the provided andsnapped in place on the cross wire of a harp frame. With theaexception of the curvedfingers-fii andibd, the studelement .50 is thesame as thatillustratedin Fig. 2 and functions in the same manner with a washer :lifi to providea connection for a lamp shade.

In my-coepeniiing. application Ser. ..No. 174,988, filed. concurrently herein, now abandoned, for ailamp shade .and method oi'making the same, the spider :is to ibexsecured .on the, lamp shade after the shade has been made.

The same type of spider which I shall -now describe-may .be used inithe lampshade of that application.
