GAS-LAMP.

Specification of Letters Patent.

Application led February 28, 1911.

' Patented Nov. *7, 1911.

Serial No. 611,430. Y

To all whom it may concern:

Be it known that I, EDGAR A. GILLiNDER, a citizen of the United States, residing at Philadelphia, Pennsylvania, have invented certain new and useful Improvements in Gas-Lamps, of which the following is a specification.

This invention relates to improvements in gas lamps.

In gas lamps, particularly of the inverted burner type, Where a plurality of burners are present, the globe beco-mes heated, and where the lamps are exposed, as in out-ofdoor lighting, rain, or frequently wind or drafts of air striking the heated globe will cause it to break. Shades are objectionable as they interfere with the desired distribution of light and change the appearance of the lamp, and, further, do not furnish the full protection desired.

The main object of this invention is to provide an improved gas lamp in which the globe is protected from rain or from drafts of air without detracting from its appearance as a globe, or interfering with the distribution of light.

Further objects, and objects relating to structural details, will denitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention, is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a side elevation of a structure embodying the features of my invention. Fig. II is a detail view, partially in vel'- tical central section on a line corresponding to line 2-2 of Fig. I.

In the drawing, similar reference numerals refer to similar parts in both views.

Referring to the drawing, the burners, which are of the mantle or incandescent type, are arranged within the lower end of the chimney 1. The chimney is mounted on the gas supply pipe 2. The burners are inclosed by the globe 3, which is removably secured in the globe support-ing ring 4c by means of the screws 5, as is clearly shown in the drawing. This globe supporting ring is hinged at 6.

As the details of the hinge and of the chimney and burner structure form no part of this invention, I do not illustrate or describe the same herein.

The upper part of the globe, the part particularly within the heat zone of the burners, is inclosed by a protector 7, which is su ported in a spaced relation to the globe to provide an annular air chamber or space 8 about the globe. The protector 7 is supported from the flange 9, which projects outwardly and downwardly to embrace the upper end of the protector. The protector' is secured to the flange by means of the screws l0. The supporting flange 9 for the protector preferably closes, or substantially closes, the upper end of the chamber 8, so that there is substantially no circulation through this air chamber, except such as results from the loose it of the parts.

The lower end of the chamber is open. The globe is removable through the protector. The protector is spherically curved to correspond to the spherical globe, which it incloses, so that the annular air space 8 is uniform. The lower end of the protector is flared slightly outwardly, so as to more effectively deliver' the water falling thereon away from the globe. The globe is provided with a small opening 11 in its bottom for the escape of condensation.

The protector is preferably transparent," that is, clear, so as not to be conspicuous, and, indeed, at a short distance away, its presence is not ordinarily observed. It does not interfere with the globe appearance of the lamp, which is very desirable, particularly in street lighting, and, further, it does not interfere with the distribution of light. If desired, this protector may be frost-ed, or otherwise rendered translucent, as the upper portions of the globes and sometimes the entire globe is so treated. My improvements are, however, particularly designed by me for use on lamps intended for street lighting, where clear or transparent globe effects are sought, and while the protector accomplishes the result of protecting the globe so that it is not broken by exposure to rain or wind, it, as stated, does not interfere with the appearance of the globe or with the distribution of light.

I have illustrated and described my improvements in the form in which I have embodied them in practice. I am aware, how

ever, that considerable modification in structural details are possible without departing from my invention, but as such modifications will no doubt be readily understood by those skilled in the art to which this invention relates, I have not attempted to illustrate or describe them in detail herein.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

l. In a gas lamp, the combination of an inverted burner; a chimney; a globe inclosing said burner; a globe protector surrounding the upper portion of said globe; and a globe supporting ring pivotally mounted on said chimney, said ring being provided with an outwardly-projecting supporting flange for said protector whereby the chimney and protector swing together to afford access to the burner, said protector being supported in a spaced relation to said globe to provide an annular air chamber or space between it and said globe, the upper end of the chamber being closed by said supporting flange, its lower end being open, the said globe being adapted to be inserted or removed from said supporting ring through said protector.

2. In a gas lamp, the combination of an inverted burner; a chimney; a globe inclosing said burner; a globe protector; a globe supporting ring pivotally mounted on said chimney, said ring being provided with an outwardly-projecting supporting flange for said protector whereby the chimney and protector swing together to alord access to the burner, said globe supporting ring being provided with globe engaging means arranged above said protector supporting liange, said protector being supported in a spaced relation to said globe to provide an air chamber or space between it and said globe.

3. In a gas lamp, the combination of an inverted burner; a chimney; a globe inclosing said burner; a globe protector surrounding said globe; and a globe supporting ring pivotally mounted on said chimney, said ring being provided with an outwardly-projecting supporting flange for said protector whereby the chimney and protector swing together to afford access to said burner.

In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
