In some eases; the inner reflecting' covering 7 may {be i made of a ,sui t v :sble composition or materiel which becomes i nable celluloid known as eele'stoid,"such name being a registered trade inerk. or The 53pm rn' ziche "or othergfplastic material G formingthe outer layeror portion of the covering is ma defin et'grnould to fit thegexteriorp of the inner lat-yer or portion of the coverin'g an'd 'w hilein such' mould and when art1a11ynr =the 3 inner layer or portion is placed position.

In cases where the reflecting layer A next the glass is formed'of non-inflammable celluloidor similar material, an intermediate layer A (Figure 6) ofpaper or other suitable material is arranged between the celastoid or similar material and the outer layer C of papier mach. If areinforcement, e. g.
of textile material E a (Figure 7) is employed, it may be advantageously arranged between the layer of paperand the outer covering of papier mach.
One advantage of applying the papier mach covering as above mentioned is that the papier mach does not shrink into the spaces between the prisms, ribbings or the like on the outer surface of the glass reflector, but rests only on their outer edges,
thus avoiding optical contact with the sur-' ,faces of the prisms. Y covered may The glass reflectors gpractical work. v I
By using a composite reflector consisting of a glass reflector having a prismatic: or
ribbed outer surface, and a paper miich coveringor shape lined with a white or other colour reflecting substance the efficiency of the shade as a light refiectoris'increased;
and the outside of the glass reflector having prlsmsi ribbings or the like is kept perfectly clean, so that the prisms are-maintained at their highest efficiency, which would not be the case if they were to become dirty.
7 Moreover the composite reflector weighs less than would be the case if the outer covering were of metal thusputting less strain upon the fittings holding it.
' y In order to prevent cracking of the outer papier mach layer during the. contractionor other resilient materialmay be arranged.
of thesame :which -takes place during .the drying, a' layer ofasbestos A" (Figure 8) betweenthe inner (A) and outer (C) layers or parts of the covering. Such asbestos layer A may also be' continued inwards,
' asshown, so as to form the uppermost part I ;.of the inner layer, i. e. at the place where I theshade fits closely round the holder of the a glow lamp and the temperature "is consequently a maximum.
be of all the shapes used in By treating the exterior surface of the outer covering with a suitable waterproof enamel, paint or varnish, the coyering may be adapted for use in the open air.
The covering may be reinforced preferably by one or more layers of open mesh textile fabric, as at E, Figure 7; or by means of metal rings or frames spun to fit the exterior surface of the inner or outer layer. Such metal rings or frames may have fingers or lugs formed thereon to engage the flange D so as to retain them in position.
The papier mache may be decorated externally in any colour, or coated to imitate bronze or other metal.
