Specification of Letters Patent. Pate t d pl 34 19115 application filer! July 31; 1914. Serial No. 854,252.

To all whom z'tmay concern:

Be it known that l, GUY B. COLLIER, a citizen of the United States, residing at Kinderhook, in the county of Columbia and State of New York, have invented certain new and useful Improvements in Gas- Lamps; and it do hereby declare the followgas lamps which are employed in connection with street lighting.

In street lighting work mechanism is conveniently employed for automatically lighting and extinguishing the light Without necessitating the manual. intervention of the operator.

One object of the present invention is to provide a street lamp of an improved design which incorporates in a compact space automatic mechanism for lighting and ex-.

tinguishing the lamp.

With this object in view, the various features of the invention consist in certain novel features of construction, combinations, and arrangements of parts hereinafter described and claimed the advantages in the art from the following description.

in the accompanying drawings illustrating the preferred form of the invention, Figure 1 represents an elevation of a street lamp embodying the several features of the invention; Fig. 2 is a detail showing upon an enlarged scale r elevation of the top of the lamp; Fig. 3 is a detail illustrating a longitudinal section of the construction shown in Fig. 2; Fig. l is a cross-section "upon the line 44 of Fig. 1; and Fig. 5 is into place and the head indicated generally at 5 is then secured to the sleeve by a plurality of cap screws 7. The sleeves 6 are all 'made with a common outer diameter and This portion of the lamp is varying internal bores to enable one size head to fit varying sizes. of posts. 1n order to improve the general appearance of the lamp and to cause the post to conform to the lines of the head, a separable ornamental sleeve 8 is made in two parts and clamped to the post in any suitable manner as shown clearly in Figs. 1 and 4.

The head 5 of the lamp comprises a substantially cylindrical housing 10 mounted directly upon the post and supporting a globe 11. The upper end of the globe is open and is surmounted by a ventilator having a perforated ventilator collar 13 and a ventilator base 14 supported upon the upper end of the globe. directly upon a globe base 15 and the globe, ventilator base and lobe base are secured together by a plura ity of clamping rods 16. These clamping rods extend through The globe is supported the globe base and lugs 17 formed uponthe ventilator base and are provided with lock nuts 18 upon their opposite ends to' draw the several parts together and lock thGIILSEH curely in place. The ventilator collar 13 is provided with an ornamental cap 20, as shown clearly in Figs. :2 and 3, which has a knob 21 supported upon its upper end and threadedly connected with a. clamping rod 23 which connects the knob with a cross piece 24 firmly clamping the ventilator collar, ventilator base and cap together. It will be observed from an inspection of Fig. 3 that the cap 20 flares outwardly and extends down below the perforations in the ventilator collar 13 thus permitting the exit of the burned gases therefrom, but preventmg the entrance of rain or moisture to the interior of the lamp. In order'to further render the interior of the lamp water-tight,

the ventilator base 14 is provided with an annular apron 25 which extends over the upper portion of the globe 11, as shown clearly 1n Fig. 3. In addltion, the globe base 15 is provided with an annular weather ring 23 which extends completely. around the globe base insi of the globe and prevents any moisture hich may seep in between the bottom of the globe and the base from working further into the lamp. The globe is clamped to the base at its lower end by a plurality of lugs 28 formed upon the base and a clamping screw 27 threaded in one of the lugs and bearing against the outwardly flanged lower edge of the globe.

In order to permit of convenient access with an inturned upper end extending I and is secured thereto by a locking pin'32.

through a flange 31 formed upon the base The vertical portion of the trimming rod passes loosely through a guiding lug 33 formed upon the interior of the housing and the lower portion of the trimming rod car ries a pivoted locking latch 35 normally pressed out by a spring 36 and engaging the upper face of the lug 33 to hold the globe and sustained parts in an elevated position until released by the operator. The outward movement of the locking latch is conveniently limited by a pin 37 secured to the trimming rod and engaging in a recess formed inthe latch, 'as shown clearly in Fig. 3. In'ordcr to permit the draining of whatever moisture collects in the lamp either by condensation or otherwise, a plurahty of passages 4.0 are formed in the housing and lead out from the lowest portion of the interior of the housing. Air is conducted to the interior of the lamp by tapered air passages 50 formed in the upper portion of the housing, as shown clearly in Fig. 3. Both the passages 40 and 50 may operate to supply air to the interior of the lamp or act as drain passages to carry away the moisture. It will be noted from an inspection of the drawings that the passages ii are inwardly and that th walls of the ins sages converge to a small opening upon the outside thus permitting the intake of air without causing a draft in the interior of the lamp.

As stated previously, mechanism is conveniently embodied in this type of lamp for lighting and extinguishing the lamp automatically, and in the preferred form of the invention, this mechanism is that shown and described in my co-pending application, Serial No. S36,88;+,'filed May 7, 1914:. The supply of gas is conveyed to the lights by a main riser -l-il extending upwardly through the post and supporting the control mechanism 42 in the central portion of the housing 10. The gas'is led fromthe control mechanism by a main supply pipe 43 and a pilot supply 44 extending upwardly from the mechanism into the globe 11 to feed the main and pilot burners in the usual manner. It will be observed in this construct-ion that the gas lighting'mechanism is compact in form and occupies a relatively small space in the interior of the housing without detracting from the external appearance of the lamp as a Whole. In order to have convenient access to the lighting lnecl'lttlilslll, the casing inclosing the mechanism is provided with a hinged cover l5 and the lions ing 10 is provided with a similar hinged cover or door 4L6 which may be locked in any suitable manner to prevent tampering with the mechanism.

While it is preferred to employ the specific construction and arrangement of parts shown and described, it will be understood that this construction and arrangeu'icnt is not essential except so far as'specified in the claims, and may be changed or modified without departing from the broader features of the invention.

The invention having been described, what is claimed is 1. A gas lamp having, in combination, a post, a substantially cylindrical housing supported upon the upper end of the post, a gas control mechanism located inside of the housing, a main riser extending upwardly through the post and connected to the mechanism, a globe supported upon the housing, and means for elevating the globe relative to the housing.

2. A gas lamp comprising a lamp post, a sleeve fitting tightly to the top of the post, a housing supported upon the top of the post and clamped to the sleeve, a gas control mechanism supported in the housing, a sectional ornamental sleeve surrounding the post below the housing, and a globe supported upon the housing.

3. A gas lamp comprising a post, a housing supported upon the post and having inwardly flaring air and drain passages formed therein at the top and bottom of the housing, respectively, to permit the entrance of air without draft and draining of moisture, a globe supported. on the housing having an opening in the bottom communicating with the housing, and a ventilator surmounting the globe.
