RING-SHADE FOR HYDROCARBON-VAPOR LAMPS.

SPECIFICATION forming part of Letters Patent No. 666.778, dated January 29, 1901.

Application filed August 10,1900. Serial No. 26,518. (No model.)

To all whom, it may concern:

Be it known that I, WIRT STANLEY Quie- LEY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Ring-Shad es for Hydrocarbon-Vapor Lamps; and I do hereby declare that the following is a full, clear, and exact description of the same, such as will enable others skilled in the art to whichit appertains to make and use the same.

Frequently in street-lighting where hydrocarbon-lamps are employed the globe or shell inclosing the burners is shattered or otherwise damaged by reason of its exposure to rain, snow, and sleet. This is due to the intense heat to which the globe has been subjected, which expands the glass,'and then to the instant contraction when the shell is suddenly wetted by such exposure to the elements.

It is the object of the present invention to overcome this annoyance; and,broadly stated, it consists in providing a transparent or translucent diaphragm or skirt which shall inclose the greater portion of the globe, but which will not reduce the light-rays nor cast a shadow.

The nature, characteristic features, and scope of my invention will be more fully understood from the following description taken in connection with the accompanying drawings, forming parthereof, and in which Figure 1 is a side elevational view of a lamp, showing one way of carrying out my invention, the same consisting of a cylindrical shade hinged to swing downwardly. Fig. 2 is a similar view of another form of globe-protector consisting of a two-part cylindrical shade,

the two parts being hinged to swing laterally, as shown; and Fig. 3 is an elevational view of a lamp provided with a cylindrical shade madeto telescope the globe.

Referring to Fig. l, the lamp is the wellknown Kitson system,provided with the usual globe-support (1 and glass globe or shell b. The guard I employ to protect the globe consists of a cylinder 0, preferably of glass, provided at its top with a metal band 61, which is hinged to the globe-support, as at e. The

cylinder or shade c is supported by metal strips f, depending from the band 01 and generally four in number, which are bent under the lower edge of the shade c to constitute lugs g. The shade is held in place in any suitable manner-for instance, by the catch h. Access can readily be had to the globe b by releasing said catch, whereby the shade will swing downwardly, as indicated by the dotted lines.

In the construction Fig. 2 the cylindrical shade or skirt has the general form Fig. 1, but is made up of two semicircular members 0 c hinged'at i, so as to swing laterally, and retained by catch h.

In Fig. 3 I have shown the cylindrical shade or skirt as telescoping the shell I). It is similarly constructed as the shade Fig. 1; but here the strips fare provided in any suitable manner with rings 2', which ride on the harps j, the latter being provided with limit-pins Z for the rings '6 to bear against when the shade is lowered to prevent the latter from being shattered by being brought into forcible contact with the curved portions of the harps j. The shade is retained in its normal raised position in any suitablemanner-as, for instance, by the spring-clip h. The dotted lines indicate the position of the shade When lowered.

It Will be obvious to those skilled in the art to which my invention appertains that modifications may be made in detail without departing from the spirit thereof. Hence I do not limit myself to the precise construction and arrangement hereinabove set forth and illustrated in the accompanying drawings; but,

Having thus described the nature andobjects of my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A globe-protector com prising a transparent cylinder, a metal band attached to the upper periphery of the cylinder, and a series of individual strips depending from said band and bent under the lower periphery of the cylinderto constitute a seat therefor, substantially as described.

2. The combination with the globe and globesupport, of a transparent cylinder surrounding the globe to near the bottom thereof, and a seat or support for said cylinder movable in respect-to the globe, substantially-es described. said-strips,--sli bstantially-a,s described. 10
