Application filed November a7; ma, Seria1 No.733,8 67.

To-all whom it may concern Be it known that I, FERDINA I a citizen-of the United States, residing at descent lamps.

Saginaw, in the county of Saginaw and State of Michigan, have" invented certain:

new and useful Improvements in Lam Structures, of which the following is a specification. i l

This invention relatesto improvements in lamps, and more particularly to reflector and shade attachments for inverted incan- The object in view is the pro'ecti'on of a maximum number of light rays ownwa'rd-l from the oint of illumination, and wit this object 'in view the invention comprehends the disposition of a shade and a cooperating reflector disposed for supplementing the reflection afforded by the shade with out interfering with air circulation. The invention further includes the disposition of a reflector sustained upon the burner supporting tube and a shade suspended therefrom in appropriate relative position with, respect to the light disposed at theterminusof the supporting tube.

' The inventlon also comprises certain other novel constructions, combinations and ar-' rangelnents of parts,=as will be hereinafter specified and claimed.

n the accompanying drawing Figure 1 is'a view partly. in elevation and partly in section of a light structure'embodying the.

features of the present. invention. Fig. 2 is a transverse section taken on the plane indicated by line 2'2 of Rig. 1 and looking downwardly,parts being broken away. Fig.

3 is an enlarged detail verticalsection taken approximately on the line indicated by line 3'3 of Fig. 2. Fig. 4 is an enlarged detail vertical section of a fragment of the parts adjacent the point of supporting engagement with "the supporting or supply pipe. Fig. 5- is a. longitudinal, vertical, central section through the mantle support, a fragment of .the mantle being shown and the also constitutes parts being shown .on an lenlargedscale. ig. 6 is a top plan view of. the mantle support.

Referring to the drawing by numerals, .1 indicates a gas su ply pipe or tube which the supporting tube and i which is supplied with gas through a mixer NnPmszmr;

2.- To the lower end of the pipe 1 is connected the incandescent mantle support 3 provided with a mantle 4. Tube 1 is provided with an annular head 5 spaced above fthe'. connection or support 3. 'The bead 5 may; obviously-either be formed integral with the supply pipe I or be formed b a to the pipe in any separate ring attached sultable manner. a v

'The mantle support 3, as clearly indicated in Fi 5 and 6, consists essentially of a tube ormed preferably with integral out standing arms 3 supporting a surrounding ring 3"; whichring is formed with an annular groove 3 into which is secured the upper end of the mantle 4,said mantle being confined in the groove by a retaining ring 3 which may be a cord, tied or otherwise fastened in position, and if a cord it is formed, of course, of the same material as the mantle. The ring 3" is preferably formed integral with the arms 3.

Surrounding the head 5 is a ring (3 having an inwardly turned annular flange 6 dis.- d aboveand adapted to rest upon the end 5- Outstanding radially and preferably inclined slightly downwardly from and preferably formed integral with the ring 6 "are supporting arms .7, 7 each terminating at its ower outer end in a hook 8 disposed to underlie the inclined outer surface of an inverted frusto-conical ring 9. The lower edge of the ring 9 is preferably stiffened by being thickened and provided at suitable intervals with set screws 10 adapted to engage the upwardly flared end of a mantle globe ll inclosing the mantle 4. The globe 11 may be of any ordinary type and is preferably provided with air circulation apertures 12, 12.

Disposed above the ring 6 is a reflector 13.

tor l3 terminates in an upstanding flange it having tabs 1;) struck therefrom at various points about the fla iige. A spider 16 is arranged with an opening having an annular boss 17 disposed to fit about the pipe 1, with the arms of the spider extending radially from the pipe to the flange 14, there being an arm of the spider for each tab 15, the respective arm of the spider extending beneath the respective tab 15 in position for resting upon the inclined outer portion of the reflector 18. Thus the reflector 13 is comparatively rigidly sustained on the pipe 1 in proper relative position with respect to the burner and globe beneath.

Hooks 18 are spaced about the reflector 13 and are preferably provided in a number upper hook portion of each hook 18 engaging the flange 14 adjacent one of the tabs 15, the shank of each hook 18 being pendent from the flange and at its l'ower end being provided with a pair of-spaced hooks 18 adapted to engage suitably disposed-apertures in a ring 19. The ring 19 converges downwardly in a ratio proportionate to the upward flare of the upper end portion 20 of a shade 21, the said flared portion 20 being surrounded and clamped by the ring 19.

The said ring 19 preferably consists of a strip of metal or other suitable material having its end portions bent and detachably secured together as oy bolts or other securing means 19, 19. The shade 21 is formed of suitable mate ial with preferably an ap propriate reflecting inner surface and shaped and dimensioned relative to the size and disposition of the light in the lobe 11 for effectively projecting the light rays downwardly, supplemented by theprojection of light rays reflected from the under surface of the reflector 13.

Having thus described the invention,what is claimed as new is: i

1. In alight structure, the combination with a support and a light pendent therefrom, oi an inverted, substantially conical reflector above the light, a shade spaced be; low the upper portion of the reflector and disposed for facilitating circulation of air past the light through the space between the reflector and shade, and a globe for the light mm, of a reflector sustained by said support above the light, said; reflector being of substantially inverted conical form, anda shade disposed to substantially surround the light and having its upper portion spaced below and of substantially the diameter of the greatest'diameter ot' the reflector, said shade flaring (lmvnwurdly fI OHl its upper portion.

3. In a light structure, the combinatipn,

In a light structure, the combination, with a supporting supply tube and a light pendent therefrom, the said tube being formed with a head, of a substantiall conical reflector dis osed in an inverte position above the bead and having its apex truncated and surrounding the supply pipe in position for being supported by the head, a spider engaging the supply pipe and having arms outstanding therefrom to and engaging the outer portions of the reflector, the reflector being formed with an annular upstanding flange and means engaging the arms of the spider, spaced hooks having hook portions engaging the flange and shanks pendent therefrom, the lower end portion of each shank being formed with a hook, and a shade support engaged by the hooks at the lower ends of said shanks.
