. snrMous, INCORPORATED, OF TION-OE NEW YORK;
SOIlVAY, NEW YORK, A CORPORA- REoEPTAcLE FOR mcANoEs cENr :LE'TRI'Q LAMPS.
Specification of Letters Patent. Application filed March 16,1905. Serial No. 250,164.
patented April 10,1906.
' vcuse, in the county of Onondaga and Stateof NewYork, have invented certain new and useful Improvements in'Receptacles for Incandescent Electric Lamps; and I do hereby declare the followin to be a full, clear, and exact description 0 the invention, such as will enable .others skilled in the art to which .it appertains to make and use the same.
My invention relates to receptacles for incandescent lamps; and it consists in. a new construction of receptacle which is strong, compact, easily and firmly secured in lace,
and when so installed presents a sight y ex- ,terior, all the securing-screws and connections being covered and well protected from short circuit and leakage of current.
It consists, essentially, of two parts made of porcelain or other suitable insulatin material, a base carrying the Wire terminas and first secured firmly in position by one or more securing screws; The base is of s'ufiicient length to permit good se aration between the metallic parts and en 'ciently thick to be strong enough to carry the cover and to have long side walls over which there is little dan- The cover almost completely ger of leakage. covers and protects the base, to which it is "secured by a single screw, and is so proportioned as-to leave an open channel of consid -erable size 'between'its inner surface and the base, forming an insulating air-space. All the metallic connections between the parts are positively insulated by walls of insulating material.
I have shown a desirable embodiment of invention in the drawings herewith, in,
m wl iich the reference-numerals of the specification indicate the corresponding parts in all the figures.
Figure I is an end elevation of my receptacle. Fig. II is a cross'section at right anglcs to the preceding. Figs. III and IV are respectively top plans of the assembled receptacle and of the cover. Figs. V and VI are respectively plan and side elevations of the base. Fig. VII shows a base made for one securing-screw only.
In the figures, 1 indicates the base, practically rectangular in form, having tips 2 3 of:
unequal size; sid projections-4. 4 for supporting in recesses 5 6 the wire terminals 8 9, hav ing-their outer ends slightly bent up the better to retain the wires under the bindingposts and secured to the base b whose heads may be covered, wit insulatin cement. The wire terminals are positive y separated bythe curved wall 12. The base deeplarger portions that the screw-heads may be surik thereinto givegood separation from the nearest metallic part.
at the ends notches 22 23 of unequal size respectively to fit the tips 2 3 and guide the assembling of the parts in proper relations. In the mouth of the cap aresecured the lampterminals 25 and 26, of which the-outer ter- 'minal 25 is securedby screws 27 and nuts 28, one of which carries a resilient contact-piece 29 to make contact with one of the wire terminals when the parts are assembled. The central terminal 26 is held in place bythe sin-' gle screw 31, which also connects that terminal to the opposite wir'e terminal and firmly secures the cap to the base. On the upper surface of the cap the tubular portion 32 is formed to fit within the curved wall 12 positively to insulate this connecting-screw. To the screw is fitted a short coil of wire toretain the screw in the hole and prevent loss thereof when the parts are not assembled. It will be understood that, if desired, the split washer forming the central terminal may be central terminal.
as those may be varied without departing from the spirit of my invention.
. By my invention I produce a receptacle well adapted foruse in many locations, such as cornices, 800. While the base is sufficiently large to obtain strength and good separation closed within the margin of a cap of moderate size, so as to becompact. The base is first firmly secured in position and the cover firml whic has also electrical functions. It 'wil be observed that the side air-spaces give the omitted and the head of the screw act as such I do 'not desire to limit myself to the exact form and arrangement of parts here shown,
is secured in position by one or two securin screws, fitting screw holes 13, made w t 20 indicates the cover, having margin 21 entirely surrounding the base, but having between the parts, it is not too large to be inattached thereto by the single screwi r65 best insulation and insure against the collectmake connection therewith and to secure the cover to the base, said cover having notches su having marginal side walls to cover and protect t air-channels between said we ls and the base,
- an outer terminal arranged in said mouth, 3
- one of said screws on the upper surface of the electric connections therewith and firmly to secure the cover to the base.
' and thin tips at each end of different widths,
ters Patent, is
.said lamp-terminal on the cover, a resilient of saidlamp terminal screws and adapted to 'ing of dust, moisture, &c., andthat the math tallic connections between the parts are positively separated by insulating projections and corresponding depressions. th
