5 Claims.

This invention relates to a certain new and useful improvement in street-lamps and. the like.

Structures of the type stated. usual1y comprise a glass unit or globe, a standard. for sup- 5 porting the globe at a desired elevation, am]. an

ornamental fixture commonly designated. a canopy fitting an the globe, and very frequently the fragile glass unit becomes broken during the assembling 015 the parts, as we11 as also during disassembling for cleaning and. inspection, the cost of maintenance of the lighting system being increased accorclingly.

Our present invention has hence for its chief object the provision in such a structure of sim- 15 p1e, inexpensive, am]. durable means for cushioning the canopy 011 the globe and the globe both during inspection and cleaning and. when mounted. =on the standard, the operative assembling of the parts being thereby greatly facilitated. and. breakage largely reduced. With C01- responding decrease in maintenance costs and charges.

And With the above and other objects in view, 0m invention resides in the novel features of form, construction, arrangement, and combination of parts presently described and. pointed 01112 in the claims.

In the accompanying drawing- Figure 1 illustrates in elevation a street-lamp equipped. with globe cushioning means of nur invention;

Figure 2 is an enlarged detail sectional view taken approximately on the 1ine 22 Figure 1; Figure 3 is a similar view taken approximately 011 the line 33, Figure l;

Figure 4 is a plan view cf one of the globe aushiom'ng members of the lamp-structure; and

Figure 5 is: a plan view of one of the globe am]. canopy retaimng rings of the lamp-structure.

Referring now more in detail and by reference characters to the drawing, which illustrates a preferred embodiment of our invention, A designates a suitable Standard or post adapted in upsbanding relation, as Will be understood, for embedment a1: its 10Wer end. (not shown) in the gro-und.

Suitably fixed. to am]. upon the upper end of post A, is a fixture B comprising an upwardly presented globe-supporting ledge or flange I and. a surrounding ring 2, the latter being provided with a suitable number of circumferentially spaced threaded openings 3 for accommodating a like nu.mber of globe-fastening or securing screws 4.

Forming part of the lamp-structure, is the glass unit or globe C, which has the usual shape or contour best seen in Figure 1, and which has a base or end-portion c provided with an annular recess or groove 5 am]. suitably diametriwardly presented ring 7 for surrounding the upper end-portion of the globe C and likewise provid.ed with a suitable number of threaded openings 8 for accommodating a like number 0f fastening members 01' screws 9.

E designates cushion constructed of rubber 0r other preferably elastic 01 resilient mate1ial and of fing formation for snugly and tight- 1y fitting 011 am]. embracing the annularly recessed. end-portion c of the globe C, as best seen in Figure 3, the member or ring E being thicker centrally, as at e, than a1; its opposite side portions e and e" to obviate slippage of the ring when fitted as described on the globe, and the ring E having its one side portion e extended. sidewise, as it may be said. for interposition between the globe C and the upper marginal portion of ring 2 and. its other side portion e" similarly extended to overlap the globe endportion c in such manner as 130 prevent and. obv1fate any contact between the globe C and. fixture-ledge l. Furthermore, it may be here stated, when the globe C is detached from the post A and endwise placed. on the ground 0r other support, the so overlapping side-portion e" of the ring E fully cushions the glotze against injury or breakage.

F designates a split spring ring preferably of concave-convex cross-section, which, in practice, is spring-wise encirclingly fitted within the recess 5 and over the thicker central portion e of the cushioning ring E for distributing about the globe C the fastening pull of the several screws 4-, as will be understood; while E and F designate similar cushioning and. retaining members, respectively, which, in 1ike manner, are fitted on the globe C ab its upper end-portion, as best seen in Figure 2 for securing the canopy D upon the g1obe C and cushioning the globe C from contact With, and breakage by, the canopy D, the sideportions of the member E being, as shown, similarly sidewise extended for fully overlappingly cushioning the globe C from any direct contact with the ledge 6 or ring i of the canopy D.

It Will be understood that changes in the form, construction, arrangement, and. combination of the several parts of the lamp-structure may be made and substituted for those herein shown and described. without departing from the nature and principle of our invention.

Having thus described our invention, what we claim and desire 130 secure by Letters Patent 15,--

1. In a 1amp structure, a globe having an annularly recessed end portion, and a rubber cushion of ring formation disposed about and embracing the recessed end portion of the globe, said. ringcushion having an inner arcuately depressed. portion of relatively increased thickness and. latera11y extending relatively thin portions integrally fornied on each side of the inner portion.

2. In a 1amp structure, a globe having an annularly recessed and. portion, a rubber cushion of ring formation disposed about and embracing the recessed erid portion cf the globesaid fing-aushion having an inner arcuatly depressed portion of relatively increased thickness and. laterally extending relatively thin portions integrally formed 010 each side of the inner portion, and means operably mounted in 1:he lamp st1ucture for impinging engage1nent With the inner portion of the ring-cushion whereby cause any accidental shock to be initially exerted upon the said inner portion.

3. In a 1amp structure, a globe having an annularly recessed and portion, a rubber cushion of ring formation disposed. about and embracing the recessed end portion of the globe, said ring-cushion having an inner arcuately depressed portion of relatively increased thickness and laterally extending relatively thin portions integrally formed on each side of the inner portion, a split ring for impingingly engaging the inner portion of the cushion, and screw means operably disposed in the lamp structure for urging the ring into the s-aid inner portion of the cushion in such a manner that shocks exerted upon the lamp structure Will cause temporary deformation of the said inner portion of the cushion and attendant momentary thickening of the outer portions thereof whereby neutralize and dissipate said shock.

4. In a larnp structure, a globe having an annularly recessed end portion a rubber cushion of ring formation disposed about and embracing the recessed and portion of the g1obe, said ringcushion having an inner arcuately depressed portion of relatively increased thickness and laterally extending relatively thin portions integrally formed on each side of the inner portion, said thin portions being adapted to conform to and embracingly engage the respective surfaces of ehe globe adjacent 110 the recessed portion thereof, a split ring for impingingly engaging ehe inner portion of the cushion, and screw means operably disposed in the lamp structure for urging the ring into the said inner portion cf the cushion in such a manner that shocks exerted upon the lamp structure Will cause temporary deformation cf the said inner portion of the cushion and attendant momentary thickening of the outer portions thereof whereby to neutralize and dissipate said shock.

5. In a lamp structure a globe having an annular1y recessed end portion, and a rubber aushion 0f ring formation disposed about and embracing the recessed. end portion of the globe, said ring-cushion having an inner arcuately depressed portion of relatively increased thickness and laterally extending relatively thin portions of substantially equ-al thickness integrally formed on each side of the inner portion.
