SPECIFICATION forming part of Letters Patent N o. 512,026, dated January 2, 1894.

Application tiled April 25. 1893. Serial No. 471,769. (No model.)

To all whom it 17mg/ concern..-

Be it known that I, MICHAEL HICKS,'of New York city, New York, have invented certain new and useful Improvements in Gas-Lamps, of which the following is a specification.

This invention relates to a gas lamp of the class which are now generally used in railway cars and secured to the Vceiling and being pendent therefrom. In the general construction ot' this class of gas lamps there is provided in addition to the supporting arms or brackets a ring secured to the lower ends of said arms with a hinged member to sup-V port a glass globe which is held inan inverted position, the stationary member of the ring having a catch to hold the globe ring.

l A chimney is provided above the glass globe and this chimney delivers through a tube to a ventilator formed in the ceiling of the car. A burner is secured centrally within the body of the lamp, and these burners are sometimes of the Argand type and sometimes a cluster of burners is employed.

The object of this invention is to simplify the construction of lamps of this character, to reduce the weight and bulk of the metal parts, to provide a reflector which shall serve as a chimney and which can be removed downwardly when the glass globe is unhinged and without the necessity of taking the lamp down from the supporting ceiling.

In the accompanying drawings, Figure 1 is an elevation showing the lamp in the position of use. Fig. 2 is a similar view, partly in section; and Fig. 3 is a cross sectional view.

In the drawings, 3 represents the supporting arms or brackets, one of which is adapted to serve to, convey the gas to the burner and is provided with a stop or gas cock 4.

5 represents a burner tube which has radial pipes 6 communicating with an annular gas chamber or ring 7 to which the gas 1s supplied from the gas arm having the cock. This burner tube extends above the ring and its upper end is closed. By the provision of the annular ring, the branch arms and the extension of the burner tube above said ring a head of gas is maintained whereby the substituted.

A set screw 15 works through the threads of y said ears and through a threaded lug on the shade ring. By means of the set screw l5 these hinged arms can be drawn so as to clamp the body ofthe tubular part 12. `The lower side of this clamp ring is adapted to receive the reflector 1G which is usually provided with an outwardly Haring flange vat its top and the Ysmall set screws 18 being turned in so that their ends engage the reflector below theA flange and support it in place. Said reflector depends to about the plane of the top of the glass globe 19, and its lower margin is seated in au annular hinged ring 2O and enters loelow the inner margin of a second annular ring 21, this ring being supported at its outer edge by screws engaging the xefl rim or collar 22 which is secured to the lower ends of the arms The ring 2O can be lowered as seen in dotted lines Fig. 2 to permit the reflector to be removed or placed without detaching the supporting arms. The transparent globe 19 has its upper flared margin secured with a hinged ring 23, the latter being provided with a catch 24 by which it maybe secured to the collar 22.

The chief object of this invention being to simplify the construction of gas lamps and to dispense with all parts which would tend to obstruct the light, we call particular attention to the following features of construction and operation whenin use: The metal parts are reduced in bulk and weight as far as consistent with stability of the structure; the pendent arms whereby the lamp is supported are braced at a point intermediate their ends by the annular ring which affords a gas passage to the burner tube; the metal tubes or pipes which serve to carry off the products of combustion from the chimney are Iso reduced in diameter and simplified in construction as to provide a direct passage way delivering immediately7 under the ventilator at the upper end and' communicating directly with the reiiector at the lower end; the hinged clamping ring adapts the reflector to be disconnected and removed bodily downwardly when the globe ring is released, thus avoiding the neceslsityof removing the lamp structure from the ceiling; the reector which is usually of' opaline glass permits the passage of the rays of 1o lightsufficiently to light the ceiling of the carto relieve it from shadow, while the main body of light is reflected thereby downwardly through transparent globe 4and into the apartment.

By reducingthe number and size of the metal t 5 parts the obstruction and consumption of the rays of light are lessened; land I have found that with a lamp of this construction a better light is produced than by gas lamps having added metallic reflectors such as are now zo in common use.

Some of the details of construction maybe varied and those which are novel are pointed out in the claims.

I clair'nl. In alamp of the class described,the combination with supporting or bracket ar1ns,of

av fixed rim secured thereto, an inwardly projecting ring carried by said rim and a 'second ring hinged thereto and adapted to provide a seat or support for the lower edge of a reiiector, said last named ring being movable whereby the retlector may be removed or inserted without disconnecting the bracket arms from their supports, substantially as described.

2. In alamp of the class described, the combination with the supporting arms, of an open rim secured thereto, and two reflector rings supported on said rim and between which the lower edge of the reflector is adapted to enter, thelowxer of said rings having a suitable seat -for the. reiector and being movable whereby the reflector may be withdrawn or inserted, substantially as described.

3. Ina'lamp of the cla-ss described, the combination with the supporting arms having a ixed rim secured to their lower ends, upper and lower reflector rings one of which is securedV with and the other movably attached 5o to said rim, a pipe or tube for carrying away the products of combustion of the flame, and

a clamping ring secured to the lower end of said pipe and adapted to engage the' upper end of a reflector, substantially as described.'

4. Ina lamp of the class described, the combination with supporting arms having afixed rim at their lower ends, a refiector ring secured thereto and 'a movable reflector ring hinged thereto, a pipe or tube arranged centrally of the body of the lamp and delivering 6o to a ventilator at its top, and aclamping ring having pivoted arms adapted to embrace the lower end of said tube and means for clamping said arms thereon, substantially as described. g y6 5 5.v In a lampof the class described, the combination with the bracket arms havingafixed rim provided with a catch, a globe ringhinged thereto, a reflector ring also hinged thereto and a second reflector ring secured therewith, 7o a reflector having its lower margin adaptedvto a seat in the hinged reflector ring and to pass inside of the fixed'ring, a tube arranged centrally over the burner space and communieating with a ventilator at its top, a clamping ring provided with binding screws to hold the reflector and adapted to be removably secured to said tube and pivoted arms having a clamping screw for clamping said ring to the tube, substantially as described. 8c

6. In a lamp ofthe class described, the -combination withsupporting bracket arms one of which is adapted to convey gas tothe burner and provided with a gas cock, an annular gas chamber communicating. with the gas passage of said arm, a burner tube communicating with said gas passage, said tubeextending above said chamber whereby to provide for maintaining a head of gas above the burner, substantially as described. Y 9o 7. In alamp of the class described, thecombination with supporting bracket arms one of which is adapted to convey gas to the burner andprovided with a gas cock, of an a'nnulus secured to said arms between theirends and the hollow of which is in communication with the gas passage of the arm, and a burner tube communicating with the gas chamber of the annulus, the latter being adapted t0 brace the bracket arms, substantially as described.
