Fig. 9 is a cross sectional view of a bearing Fig. 10 is a plan View of a supporting arm in general a lamp base or pedestal I6, a shade support I! and a shade H3. The lamp base may be of earthenware or any other suitable material. On its upper end the lamp base is provided with 1y operated from a point above the shade rea central opening [9 and an outer groove as is 22, having openings 23 therein, and with a central opening 24 in its top.

As shown in Figs. 2, 3 and 7, a base member 25 having upwardly extending sides 26 is pro- A bridging member 21 is gnate. like welded to the member 25 at points 25a and has a central threaded opening 28 therein. The member 25 is provided with a central threaded opening 29 in which is positioned a hollow shank 30 which extends through the opening |9 in the lamp base l6. Inwardly extending lugs 3| are provided on the member 21 and these act to limit the upward movement of the shank 30 in the opening 29. A screw 32 passes through the opening 24 in the cap 2| and is screwed into the threaded opening 28 of the member 21 for holding the members 25 and 21 removably in the cap. In such position of the members 25 and 21 the outer arms 26 may bear against the oblique sides of the cap and the members 25 and 21 are thus limited in upward movement and are held against rotation in the cap by such engagement. A nut 33 is positioned on the shank 38 and bears against the under side of the lamp base l6 and holds the cap 2| tightly on the lamp base with its edges in the groove 20. i

As best shown in Figs. 3 and 6, arms 34 extend through the openings 23 of the cap and are fastened to the cap by means of tongues 35 which are provided on the lower ends of the arms and are welded to the cap. Bearing plate members 36 in the form of cups are welded to tongues 31 which are provided on the upper ends of the arms 34. Each of the arms 34 is initially in the form of a narrow strip of metal 38, as shown in Fig. 10, having the spaced tongue portions 31 on its upper end and the centrally located tongue 35 on its lower end. The'arms are formed by bending or rolling the strips of metal 38 into tubular form thereby bringing the tongue portions 31 together. The arms are also bent into curved form as shown in Fig. 3, thereby forming in effect, with the cap 2|, a harp frame.

Caps 39, provided with slot-like openings 40 in their sides as shown in Fig. 9, fit into the members 36 as shown in Figs. 3 and 5. The openings 49 fit around the upper ends of the arms 34 and the caps 39 are removably held in the members 36 by frictional engagement therewith.

A housing member 4| is swingingly mounted between the bearing plate members 36 by means of tubular shafts 42 extending through the bearing plate members and into the housing member. Leaf springs 43 are provided on the shafts 42 bearing against the inside faces of the housing member 4| and against the inside hubs 42a of the shafts. The leaf springs 43 act to pull the shafts 42 inwardly with the outside hubs 42b of the shafts bearing against the members 36 and cause the housing member and bearing plate members to bear against each other under spring pressure. The housing member 4| is thereby held fixed relative to the bearing plate members 36 and the arms 34 by the frictional engagement between the bearing plate members and the housing member.

The bearing plate members 36 are provided with slots 44 as best shown in Fig. 2. The housing member 4| is provided with lugs 45 which extend into .the respective slots. The lugs move in the slots with the swinging movement of the housing member and cooperate with the slots to limit the swinging movement of the housing member.

A complementary housing member 46 is provided and fits into the housing member 4| as shown best in Figs. 3 and 8. The housing member 46 is provided with a central opening 41 and with an outwardly extending rib 48. The housing member 46 is limited in its upward movement by the rib 48 bearing against the lower edge of the housing member 4|. The housing member 46 is provided with outwardly extending lugs 49 which fit into openings 50 in the housing member 4| and the housing member 46 is thereby held against downward movement out of the housing member 4|. The arrangement is such that when the housing member 46 is inserted into the housing member 4|, the lugs 49 are forced inwardly against their spring action by the housing member 4| until the rib 48 comes in contact with the lower edges of the housing member 4| whereupon the lugs 49 spring outwardly into the openings 56. The housing member 46 may be removed from the housing member 4| by forcing the lugs 49 inwardly such that they will pass the lower edge of the member 4| and then drawing the member 46 downwardly.

A switch and socket unit 5| provided in the housing member 4| extends through the opening 41 in the complementary housing member 46 and is held by the member 46 against sideward movement in the housing member 4|. A lamp bulb 52 is positioned in the switch and socket unit 5|, and the lamp arrangement is such that the bulb is located between the arms 34. The switch and socket unit is provided with a threaded shank 53 which extends through an opening 54 in the top of the housing member 4|. As shown in Fig. 4 the shank 53 and the opening 54 have fiat sides and are non-circular in form. The arrangement is such that when the lamp bulb 52 is removed or replaced in the switch and socket unit, the unit cannot have rotative movement relative to the member 4|.

A look nut 55 is positioned on the shank 53 and holds the switch and socket unit 5| from downward movement in the housing member 4|. A shade carrying collar 56 from which shade carrying arms 51 extend is positioned on the lock nut 55 and is held in such position by a lock nut 58 on the shank 53. A shaft 59 extends through the shank 53 as shown in Fig. 2 and is connected with the switch and socket unit 5|.

A circuit through the switch in the unit 5| is completed and broken upon rotation of the shaft 59. A finial or switch knob 69 is positioned on the upper end of the shaft 59 and forms a switch operating means for rotating the shaft 59.

Electrical supply wires 6| extend upwardly from the base through the shank 30, into the arms 34 and through the hollow shaft 42 to the switch and socket unit in the housing member 4|, as is shown in Fig. 3. The lamp arrangement is such that the wiring may be easily installed. With the members 25, 21, and the shank 30 free of the cap 2| and free of the base IS, the caps 39 removed from the members 36 and the switch and socket unit and complementary housing member 46 free of the housing member 4|, wires 6| which have been preliminarily separated may be passed through the shank 30 and out on opposite sides of the member 21 to the arms 34. The wires may then be pushed through the arms, passed through the shafts 42, and connected to the switch and socket unit. The lamp arrangement may then be put into finished condition with the caps 39, the complementary housing member 46 and the switch and socket unit in place and with the lamp support l1 mounted on the base l6, as is apparent.

The finial or switch knob 60 extends above the shade l8 and the shade supporting means, in-

cluding the arms 51, as well as above the housing GI, and the lamp may be switched on or off very conveniently without reaching under the shade and feeling for the switch as is usually done. When it is desired to tilt the lamp shade IS, the lamp bulb 52 and associated parts, it is simply necessary to grasp any of the movable parts and swing the housing member 4| relative to the arms 34. The housing member 4| remains in a fixed position upon being tilted due to the action of the leaf springs 43. The arms 34 which are provided with tongues 35 and 31 for fastening the arms to the cap 2| and the bearing plates 33 are easily and inexpensively constructed. Electrical supply wiring is easily installed in my improved lamp arrangement as hereinbefore described. The members 25 and 21 in the cap 2! form suitable and satisfactory means for removably fastening the shade support H to the lamp base [6. The wiring, the upper ends of the arms 34, and the slot and lug arrangement are all hidden by the removable caps 39, and there is no detraction from the finished appearance of the lamp arrangement by these parts. The slot 44 and lug 45 cooperate to limit the swinging movement of the housing member 4!, and the wires 6| cannot therefore be broken or damaged by too great a swinging movement of the housing member.

I do not intend to limit the invention to the details of construction shown and described except only in so far as certain of the appended claims are specifically so limited, as it will be obvious that modifications may be made Without departing from the principles of the invention.

I claim:

1. In a support for lamps, the combination of a pedestal having a supporting area on its upper end, a base member on said supporting area, an inverted U-shaped bridging member secured at its ends to said base member, a cap member fitting over said bridging member and around said base member, means for securmg the cap to said bridge member, and means for I securing the base member to said pedestal.
