My invention relates to lamps.

In particular my invention is concerned with that type of lamp which has a shade overlying the electric bulb and which shade has a depending skirt so as to cause the light to be directed downwardly and not directly into the eye of the'observer.

One of the objects of my invention is to shiftably mount the shade upon the lamp so that the shade may be tilted upwardly at one side of the'lamp to permit the light rays to be reflected laterally and in a substantially horizontal plane, and in such a manner that when the shade is returned to its original position it will not be permitted to swing in the opposite direction but will return to a true vertical position symmetrically overlying the lamp bulb.

A further object of my invention resides in means for holding the shade in any adjusted position;

Still another object of my invention resides in a very simple and economical construction which is at the same time highly eflicientand pleasing in appearance.

In another aspect my invention resides in providing a lamp with a supporting upright which upright is adapted to carry an ornamental panel useful for various purposes,

such for instance as carrying the name of the hotel in which the lamp is installed or carry-V ing a fraternity crest where the lamp is used by students in colleges or by carrying a club insignia.

Another object of my invention resides in arranging this panel preferably as a transparent or translucent ornamental indicia carrying member adapted to be insetted in the upright of the lamp and arranged so as not to interfere with the electrical cables which are mounted in this upright.

An ancillary object of this feature of my invention resides in the arrangement of means for replacing these panels as for repair or interchangeability and particularly in the means for hiding or masking the replacing means so that to all intents and purposes the panel is permanently mounted within the lamp and so that to all intents and purposes the panel containing upright is not provided improved lamp showing the shade construca tion in detail; v v

Referring nowtothe lamp in detail, it comprises a base 2 of any suitable construction which rigidly carries an upright 4. This upright may be of anydesired ornamental configuration but in the present instance, it comprises a substantially oval shaped portion 6 having an opening 8 so as to provide two looping arms or branches 6 and 10, which come together above the opening 8 at the point 12 and continue upwardly as at 14 to provide a socket portion 16 for the lamp proper. In addition the base 18 of the socket portion is formed as, a: sleeve and carries integral rodlike portions 20, there being preferably 3 in number, which at their upper ends rigidly support a metal cap 22 having an upper dome shaped portion 24 of substantially truly spherical contour. Substantially halfway down on this spherical dome, it is provided with a peripheral bead or shoulder 26 providing a'raised portion. If desired, this bead 26 may be replaced by a peripheral ring of punched out portions. In addition, the dome portion 24 is provided with a radially extending slot 28 which extends from the central axis of the dome downwardly to a point 30. The shade 32 has an upper dome shaped por tion 34 of circular contour to correspond to the contour of the dome 24 and the shade in addition has a skirt 36 which depends substantially to the socket 18 so as to directthe light rays downwardly; The usual elect-riclamp 38 is detachably mounted within the. usual standard socket 16 and the light 34 of the shade and thence into an ornamental fitting 44 having an aperture of two dimensions, the first to receive a coil spring 46 and the second to receive a threaded nut 48. This nut engages threads on the pin 42 so as to press the head of the bolt 44 upwardly whereby to cause the peripheral rib 26 in the dome frictionally to engage the under side of the dome shaped portion 34 of the lamp shade.

Thus, when the shade is swung upwardly to the left, as shown in Figure 2, the ornamental fitting 44 will be shifted to the right as shown in dotted lines and the shade will be tilted upwardly as shown in dotted lines in Figure 2. By reason of the raised portion such as the peripheral ring 26, the friction and wear is reduced to a minimum while atthe same time the shade isfrictionally held in any adjusted position. I

The foregoing construction is very simple and one of its particular features resides'in the fact that when it is desired to return the lamp shade to normal vertically depending position, shown in Figure 1, it is but nece sary to press upon the raised portion of the shade to force it downwardly and by means of my improved construction the shade will stop at its symmetrically depending position and will not overswing to another raised position. This is of great convenience in hotels,

clubs, fraternity houses and the like, where an attendant is desirous of returning lamp shades to their vertical positionso that the various shades will not be at difierent angles, which presents an unsightly appearance.

In another aspect of my invention,.it is highly desirable to provide lamps with an ornamental panel which may be used to indicate the ownership of the lamp or whereby the panels may be provided with appropriate indicia as for instance a club, society,

fraternity, or name of hotel or appropriate .the particular construction illustrated, I have shown mypanel as being a piece of transparentglass carrying-an appropriate symbol. This pieceof glass 50 is in general the shape of the opening 8 in theupright, In the particular construction illustrated, the

arms or branches 6 and 10 of the upright are suitably constructed so astoprovide a gut,- ter 52 in each branch and this is accomplished by forming the metal or materialof-the upright substantially as shown in Figures 4 and 5 above the opening'S in the upright. I alsoyprovide a keeper 54 which is likewise provided with a central opening 56 and two branch arms 58 of corresponding. shape to fit snugly within the open side of the upright substantially as shown in Figure 4. This keeper is provided with. two lugs or cars 60 and 62 which are perforated as at 64 to receive screws 66 for holding the keeper in position with the panel 50- assembled therein. It will be noted that by reason of my construction I am enabled to provide a keeper'which balances the ornamentation on the other side of the upright and will substantially hide the lines of the keeper so that without a very careful inspection, the presence of the keeper or the presence of the opening in the upright cannotbe detected.

In addition, it will be noticed that by my construction I am enabled to pass the electric wires or conduits 66, which pass upwardly through the base 4, in. a mannersuch that a single wire or cable will lie in' a separate gutter 52 on each side'of' the opening 8 and so that these cables above the opening will. then come together and pass upwardly through the hollow portion 14. It will also be seen from an inspection-of Figure 5 that the panel 50 willoverlie these cables 66 as they rest in the gutters so as to hold them in position and that the keeper 54 will hold the panel in' position.

In the construction shown in Figures 8, 9, 10 and 11, instead of inserting the panel from the front or-fiat face of theupright, I desire to insertthe same througha relatively narrow or small slot in the side of one of the branch members. To this end, the plug or keeper 68 will fill up or closea slot 70 formed I in the side '72 of the hollow, upright 74 and is retained in such position by means ofa set screw or screw 76. In this connection,the branch. wall 72 has a slotpassing entirely 1 therethrough while the opposite branch wall 80 of the upright has a slot passing only part way therethrough so as to form a gutter for the two cables or electric wires, the panel 82 holding them in position.

From the foregoing it will be seen that this panel construction provides a very efiective way in which lamps may not only be ornamented but may be proyided with a very useful adjimctive device to determine the ownership or association of the lamp.

In addition the construction is such that these panels may be very quickly and easily interchanged while at the same time the appearance of the lamp is not only enhanced. by the panel but due to the manner of mounting the same it is not apparent, without very close inspection, how the panel is detachably mounted within the lamp. Moreover, due to the presence of the panel opening in the standard for the lamp, it is not apparent how the electric cables pass upwardly through the upright to the electric lamp therebyproducing a verypleasing and somewhat mystlfying eifect.

Having thus described my invention, What I claim as new and desire to secure by Letters. Patent is:
