Application filed July 6, 1891. Serial No. 398,468- (No model.)

To all whom it may concern.- made in the form of a hollow tapering frame Be it known that we, JOHN C.

The tops of said reservoirs are provided suspended from the roofs of railroad-cars, with knobs I-I, having recesses I, Fig. 4.

In Fig. 5 the reservoirsupport is spread open just below its connection with the main hanger of the lamp and a horizontal bar T is pivoted to the said support at U. The ends of this bar are provided with vertically-arranged heads V, having chambers W, within which movable bolts X operate, backed by springs Y, coiled around the shank of said bolts, with their ends bearing, respectively, against the heads of said bolts and bottom of chambers W, the latter being pierced for the passage of the bolt-shanks, to which are attached knobs Z, which retain the bolts within the chambers and by which their heads can be drawn back into the latter for engagement or disengagement with recesses I of the reservoirs, and when thus drawn back bar T can be swung to one side and the reservoirs re moved from and attached to their support.

While we have illustrated and described a horizontal bar carried by the hanger or frame and provided with spring actuated bolts adapted to engage with recesses in the reservoirs, we make no claim herein to that specific construction, as it forms the subject-matter of claim in an application Serial No. 397,678 filed by John Kirby, Jr., June 27, 1891.

Arms a extend from the reservoir-support, carrying levers b, pivoted in slots 0 at their outer ends, which levers engage with correspondin g slots (1 in the shade-holder arms, and thus serve to lock the reservoir-holder securely in place.

Other means than those shown herein may be employed for accomplishing the same re suits, and we do not limit ourselves to such particular means.

We claim as our invention 1. In a lamp, a main hanger or frame adapted to be rigidly suspended from a car-ceiling or other overhead support, said hanger or frame being provided with outwardly-extending arms rigidly secured thereto and carrying shade-holders at their outer ends, which sustain shades over the burners, in combination with a dependent rotatable reservoir-support centrally pivoted to said hanger or frame and adapted to carry a plurality of reservoirs detachably connected therewith, and a fastening device for preventing undue rotation of said reservoir-support.

2. In a lamp, a main hanger or frame adapted to be rigidly suspended from a car-ceiling or other overhead support, said hanger or frame being provided with outwardly-extending arms rigidly secured thereto and carrying shade-holders at their outer ends, which sustain shades over the burners,in combination with a dependent rotatable reservoir-support centrally pivoted to said hanger or frame and adapted to carry a plurality of reservoirs detachably connected therewith, a fastening de vice for preventing undue rotation of said reservoir-support, and a stop for controlling the latter.

3. In alamp,a main hanger or frame adapted to be rigidly suspended from a car-ceiling or other overhead support, said hanger or frame being provided with outwardly-extending arms rigidly secured thereto and carrying shade-holders at their outer ends, which sustain shades over the burners, in combination with a dependent rotatable reservoir-supportcentrally pivoted to said hanger or frame and adapted to carry a plurality of reservoirs detachably connected therewith, a fastening device for preventing undue rotation of said reservoir-support, a stop for controlling the latter, and means intermediate said hanger or frame and the reservoir-support, whereby a steady movement is imparted to the latter.

4. In a lamp, a main hanger or frame adapted to be rigidly suspended from a car-ceiling 4 or other overhead support, said hanger or frame carrying shade-holder arms, to the ends of which are attached shade-holders sustaining shades over the burners, in combination with a dependent rotatable reservoir-support, a plurality of reservoirs detachably connected therewith, and a fastening device for locking said rotatable reservoir-support to said shadeholder arms.

5. In a lamp, amain hanger or frame adapted to be rigidly suspended from a car-ceiling or other overhead support, said hanger or frame carrying shade-holder arms, to the ends of which are attached shade-holders sustaining shades over the burners, in combination with a dependent rotatable reservoir-support, a plurality of reservoirs detachably connected therewith, a fastening device for locking said rotatable reservoir-support to said shadeholder arms, and a stop for controlling the movement of said reservoir-support.

6. In a lamp, a main hanger or frame adapted to be rigidly suspended from a car-ceiling or other overhead support, said hanger carrying shade-holder arms, to the ends of which are attached shade-holders sustaining shades over the burners, in combination with a dependent rotatable reservoir-support, a plurality of reservoirs detachably connected therewith, a fastening device for locking said rotatable reservoir-support to said shadeholder arms, a stop for controlling themovement of the latter, and means intermediate said hanger or frame and said reservoir-support, whereby a steady movement is imparted to the latter.

7. In a lamp, a main hanger or frame adapted to be rigidly suspended from a car-ceiling or other overhead support, said hanger or frame carrying shade-holder arms, to the ends of which are attached shade-holders sustainmg shades over the burners, in combination with a dependent rotatable reservoir-support, a plurality of reservoirs detachably connected therewith, and means for preventing undue rotation of said reservoir-support and for steadying said reservoirs in place, substantially as described.

8. In a lamp, a main hanger or frame adapted to be rigidly suspended from a car-ceiling or other overhead support, said hanger or frame carrying shade-holder arms, to the ends of which are attached shade-holders sustaining shades over the burners, in combination with a dependent rotatable reservoir-support,

a plurality of reservoirs detachably connected therewith, means for steadying said reservoirs in place, and a stop for controlling the,

movement of said reservoir-support, substan- IO tially as described.
