Claims.

This invention relates to an improved stand for an electrical lamp, and particularly to means producing a wide beam and for supporting the harp upon which the lamp shade is mounted, so that the lamp shade may be readily withdrawn from its vertical support, when it is required to make changes in the lamp bulb or to clean the lamp shade.

One of the objects of the invention is to provide a lamp fixture with a decorative case or body of ceramic ware or of other material, and means for mounting a lamp bulb so that its socket will be concealed by the case or body, and its light emitting section will be supported at least partly above the case or body, all so arranged that the assembly may be made Without the use of any fasteners attached to the case or body, and the illuminated lamp bulb will project light rays against the wall of the case or body.

Another object of the invention is to provide a lamp fixture with a ring frame which may be seated on the upper end of a decorative case or body, and which will support a tubular transparent or translucent guard with its lower end nested within the decorative case or body, and the lower ends of the upstanding harp frame will also be supported for vertical withdrawal.

A still further object of the invention is to provide a lamp fixture with a ring frame having offset keeper lugs and a socket supporting frame having U-shaped hook terminals which detachably engage the keeper lugs to suspend the lamp socket, lamp and conduit fittings entirely from the ring frame, so that by liftingthe ring frame from its enclosing support the entire assembly may be removed.

Still another object of the present invention proposes forming the supporting frame for the lamp fixture of a single strip of material bent into proper shape for engagement with the ring frame in a manner to properly support the lamp fixture.

Another object of the present invention proposes forming the top of the decorative case or body of a separate piece of transparent or translucent material in a manner so that some of the light from the bottom of the bulb in the lamp fixture may pass through the top of the decorative case or body.

A further object of the present invention proposes forming the supporting frame for the lamp fixture of separate sections adjustably connected together in a manner so that the position of the lamp fixture may be adjusted within the case or body to accommodate the same to lamp bulbs of different overall sizes.

It is a further object of the present invention to construct a stand for an electric lamp which is simple and durable and which can be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 15 is an enlarged partial vertical sectional view taken on the line I5-l 5 of Fig. 14.

Fig. 16 is a view of the fitting, per so, looking in the direction of the line Iii-46 on Fig. 13.

The lamp stand, according to the first form of the invention shown in Figs. 1 to 10, includes a decorative body or housing II), which may be constructed of ceramic ware or of other material, and

3 which includes the annular base wall I l, the vertical pillar or cylindrical wall l2, and the conical head l3, which is formed with an annular top ring wall I4. The lower end of the housing body or case is seated on the base plate 15, which is provided with a plurality of feet l5, and formed with a circular row of air holes I1, and a central wire hole l8.

On the upper annular wall it a ring frame it is positioned, by means of its outer circular or cylindrical wall 29, which is spaced concentrically from its inner and longer cylindrical wall 2 I, by the integral end wall 22. The lower end of the inner cylindrical wall 2| is formed with an internal horizontal flange 23, and this flange is formed with opposed downwardly

offset strap lugs

24 and 25, and with slots 2 3 and 25 located adjacent to said

lugs

24 and 25.

The end wall 22 is formed with opposed Vertical rod holes 22* and 22 and the inner cylindrical wall 2| is provided with

vertical sockets

26 and 21, permanently attached to said wall, and disposed in vertical-registration with the rod holes 2? and 22 The upper end wall I4 of the housing body Ill,

is formedwith opposed recesses 54 and M which'receive the

sockets

26 and 21, and thereby lock the ring frame l9 against relative rotation on and in the housing body. The outer cylindrical wall 29 of thering frame is wholly supported on the end wall l4 of the housing body, while the lower end flange 23 of this ring frame is supported well below the end wall 14, within the conical head I3.

Alamp socket 2B is mounted on the crossbar 29, bymeansof the conduit or pipe 34}, Which is threadedthrough the cross bar 29 and into the coupling 28 of the socket 28. A lock nut'3l is threaded on the conduit or pipe flfl-to lock the lamp socket in place on the cross bar 29.

The" cross bar 29 is connected at its ends to the vertical hanger bars "32 and 33, by means of the terminal lugs 32 'and' 33 thereof, and the connecting rivets 33'. The upper end of the hanger bar 32 is formed with a U-shaped hook 34; which projects outwardly thereof, and the upper end of the hanger bar 33 is formed with a similar hook 35.

The upper end portions of the'hanger

bars

32 and 33 are thus spaced apart so'that they may be manually pressed toward each other, and when released will resume their normal vertical positions. The two

terminal hooks

34 and 35 arereceived by the slots wand- 25 of the internal flange or seat '23 of the ring frame, and are supported by the lugs. 24 and 25, so that the upper faces of the

hooks

34 and 35 will be no higher than the top face of the flange or seat 23. A cylindrical guard G of translucent or transparent material, glass or otherwise, may then be positioned on the flange or seat 23, so that'its lower end willbe nested in the ring frame I9, a sufficient distance below the top of the same to pre vent accidental displacement of this guard.

The

vertical rods

36 and 37 of the inverted U- shaped harp frame 38 are inserted through the

rod holes

22 and 22 and pushed into the

sockets

26 and 27, which thereby support the harp frame 38 in a steady vertical plane. The upper cross bar 39 of this'harp frame is equipped with a coupling member 40, having a vertical screw 40 to which a lamp shade, not shown, may be connected.

When the

terminal hooks

34 and 35 are engaged with the slots and lugs of the internal flange 23, the lamp socket will be supported centrally of the housing body Ill. The lamp bulb B, indicated in dotted lines in Fig. 7,-will be Supported with its larger diameter above the ring fram I9, so that it can project light rays through the guard G, while the neck of the bulb will be supported so that light rays may be projected between the

hanger bars

32 and 33, against the conical head l3, thereby subjecting the housing body It to a degree of illumination less than that projected through the guard G, and producing a decorative contrast.

Due to the fact that the terminal hooks 34 and '35 will engage the inner cylindrical wall 2| of the ring frame IS, the hanger bars and the lamp socket will be held against accidental vertical movement, and the spring pressure exerted by the hanger bars on these terminal hooks will serve to hold them securely interlocked to the ring frame. The weight of the guard G will also serve to retain these hooks in their coupled positions.

The lower end of the conduit or pipe 30 is provided'with a fitting 4!, through which the current feed wires may be connected in place and extended through the conduit or pipe to the lamp socket. The fitting 4| is provided with an internal screw thread 4| adapted to receive a bushing 42, threaded through the base ring plate l5, and when this is done the ring frame I9 may be clamped against the upper end of the decorative housing body-or case [0.

The harp frame may be removed without disturbing the mounting of the socket fixture, and by liftingthe harp frame and the guard G a used lampbulb may be replaced by a fresh one. By removing the bottom bushing 42, the entire socket fixture may be removed from the housing body. The assembly of the fixture parts is completed without any screw joints, excepting that of th bushing connection.

In the modification of the invention shown in Figs. 11 and'12, the top portion or conical head 13' of the body or housing [0 is formed of a separate material which is preferably transparent or translucent. With this construction, some of the light rays from the base of lamp bulb in the socket will pass through the conical head l3 and add materially to the general appearance.

The bottom of the conical head 13' is formed with a reduced portion which is fitted into the top ofthe'body or housing ID. The weight of the conical head l3 will retain it in position; however, if desired, a mucilage of any desired type having an affinity for the two materials from which the body or housing [0' and the conical head l3 are formed may be used to fixedly secure the conical'head' l3 to the body or housing [0.

Also, in this form of the invention, the supporting frame for the lamp fixture 28 is formed of a single strip'of metal bent to provide a cross bar 29' upon which the lamp fixture 28 is mounted by means of the conduit or pipe 30, as in the previous form of the invention. Upstanding from the ends of the crossbar 29', there are the vertical hanger bars 32 and 33' formed at their top ends with the U-shaped hooks 34 and 35' engaged with the

lugs

24 and 25 of the ring frame l9.

In other respects this form of the invention is the same as the previous-formand like reference numerals are used to identifylike parts in each of the several views. r

portions 53.

the vertical position of the lamp fixture within the body or housing l" may be adjusted to adapt the lamp fixture to bulbs of different overall sizes.

The adjustable support frame 50 is compnsed of a bottom section having a cross bar portion formed with a centrally located tapped hole 52 through which the top end of the conduit or pipe 30 is threaded to threadedly receive the lamp fixture 28. Upstanding from the ends of the cross bar portion 5| there are a pair of vertical arm Extended vertically along the sides of the arm portions 53 of the bottom section, there are a pair of vertical hanger bar sections 54 formed at their top ends with the U-shaped hooks 55 engaged with the

lugs

24 and 25 of the ring frame I9. Spaced rivets 56 are engaged through the material of the bottom portions of the vertical hanger bar sections 54 and slidably pass through complementary vertical elongated slots 51 formed in the vertical arm portions 53 of the bottom section of the support frame 50.

A small projection 58, see Fig. 15, is formed on the inner face of each of the vertical hanger bar sections 54. The projections 58 are selectively engageable with complementary recesses 59 formed in the adjacent faces of the vertical arm portions 53 of the bottom section for holding the bottom section in various vertically adjusted positions on the vertical hanger bar sections 54.

is reserved to all changes and modifications coming within the scope of th invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

1. A lamp support for a hollow housing having an open top surrounded by an inwardly extended ring wall, comprising a ring frame fitted snugly into the ring wall, an outer circular wall continuing from the top of said ring frame and resting on the ring wall supporting the ring frame, a horizontal flange extended inward from the bottom of said ring frame, hanger bars depended vertically from opposite sides of said flange into the hollow housing, a cross bar mounted on the bottom ends of said hanger bars, and a lamp socket mounted on top of said cross bar concentric with. said ring frame, said hanger bars being of a length so that the top portion of a lamp screwed into said socket will be projected above the top of said ring frame.

2. A lamp support for a hollow housing having an open top surrounded by an inwardly extended ring wall, comprising a ring frame fitted snugly into the ring wall, an outer circular wall continuing from the top of said ring frame and resting on the ring wall supporting the ring frame, a horizontal flange extended inward from the bottom of said ring frame, hanger bars depended vertically from opposite sides of said flange into the hollow housing, a cross bar mounted on the K bottom ends of said hanger bars, and a lamp The bottom section and the vertical hanger bar sections 54 are formed of resilient material so that the projections 58 will snap into and out of the recesses 59 as the bottom section is moved vertically relative to the vertical hanger bar sections 54.

As the bottom section is moved vertically, the pipe will also be moved vertically, therefore, the bottom end of the pipe 30 is connected with a fitting 4| composed of a top section 4| attached to the bottom end of the conduit or pipe 30 and a bottom section 4 attachedto the bushing 42 through which the electric wire 60 enters the bottom of the body or housing It". From the bushing 42, the electric wire 60 extends upwards through the pipe 30 to the fixture 28.

The sections 4| and 4| of the fitting 4| have overlapped vertically extended portions and the vertically extended portion of the bottom section 4| is formed with a vertically extended elongated slot 6|. The vertically extended portion of the top section 4| is formed with a pair of vertically spaced rivets 62 which freely slidably pass through the vertically extended slot 6|. Thus, when the pipe 3|] is moved vertically, under the influence of vertical movement of the bottom section of the lamp fixture support 50, the top section 4| of the fitting 4| will merely slide vertically relative to the bottom section ll and guide vertical movements of th bottom portion of the conduit or pipe 30.

In other respects this last form of the invention is similar to the first two forms and like reference numerals are used to identify like parts throughout.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right socket mounted on top of said cross bar concentric with said ring frame, said hanger bars being of a length so that the top portion of a lamp screwed into said socket will be projected above the top of said ring frame, said flange having on diametrically opposite sides thereof downwardly offset strap lugs, said flange having slots adjacent the outer sides of said strap lugs, and hooks formed on the top ends of said hanger bars and extended across the top faces of said strap lugs and depended through said slots.
