Application filed January 14, 1910. Serial Ilo. 538,138.

i To all whom it may concern:

Be it known that I, HARRY A. DOUGLAS,

: a citizen of the United States, and resident tate its "manufacture, the assembling of its.

adapted for pse on automobiles; and-its object is to improve theconstruption of the frame or body of the lamp in order to faciliparts, and repairing. These objects are attained in the structure hereinafter-described and illustrated in the accompanying drawings, in which l Figure 1 is a side elevation of the lamp,

some portions being shown in section; Fig.

2 is a horizontal section through the body of the lamp, some parts being omitted; Fig. 3 is a detail in perspective of a part of one of the outer clampin retaining the side panels; Fig. 4: is a detail in perspective of an inner frame bar cooperating with the outer member; and Fig.

5 is adetail in perspective of one corner of the lamp, its open-able panel partly raised.

The lamp comprises'an upper or top sec-- tion, generally. designated by the numeral ,10, a bottom section generally designated by the numeral 11, a series of "posts or bars uniting the top and bottom sections and forming a part of the frame of the lamp,

side panels, shown as four in number, inte-r-' posed between the top and bottom members andseat'ed againstthese members and the frame postsand held thereto by means of clamping bars, which also serve to reinforce the frame posts or bars to more rigidly unite the top and bottom sections.

The top section 10 is of sheet metal and comprises a dome 12, carried by an outstanding tlange 13. The bottom 11 is also.

of sheet metal and comprises a cup is. for holding the oilfontla), this cup being carried by an outstanding flange 16 and having a downwardly-projecting extension 1.7 which mayrest upon and be secured to a supporting bracket (not shown).

The lamp is shown as being square, and its top and bottom sectionsare united by a series of posts gr bars 22,'1ocated at the cormembers for securing the top and bottom of the lamp together and k to the sliding panel ners These bars maybe stamped out of sheet metal and have their ends turned inwardly'forming flanges 23, 24 which are seated against the inner surfaces, respectively, of the top flange 13 and the bottom flange 16. The body portion of eachof these bars extends across one corner of the lamp, the center portion being flat audits side portions being bent inwardly to form shoulders 22 perpendicular to the planes of the panels and then laterally to form out;-

standing flanges 22" parallel to the planes of 1 these panels and forming seats therefor.

As shown, two of the panels 26, 27, are of glass, each being seated within a metal frame L-shaped in cross-section, theouter flange ofthis frame 26 bearing against the outer face of the glass and its instanding flange 26 being perpendicular to the plane I of the panels and fitting and sliding upon the shoulders 22 and upon the outer faces of the flanges 13 and 16, forming a snug fit with the body of the lamp for the exclusion of air currents and dust. The third panel 30 is of metal and has its edges flanged, as shown at 30 to fit againstthe shoulders 22' of thebar 22 and upon theouter faces of the flanges 13 and 1.6. This panel may be provided with a socket lug 31 for engaging a supporting bracket (not shown).- The fourth panel comprises a metal frame 32 and a sliding plate 33 having its edges folded inwardly, as shown at 34, for engaging and running upon out turned flanges of the frame portion. A lug 36 is attached for convenience in raising it, and spring lingers 37 are attached to the upper portion of the frame member 82 for engaging ribs 38 formed on the inner face of the pane adjacent its bottom, and affording means for holding this panel in its raised position to permit access to the interior of the lamp. The inner portion 32 of the frame 32 has a sliding engagement with the shoulders 22 of the frame bars 22,

The several panels are secured'in place by means of clamping bars 18 which have their endsfianged inwardly, as shown at 19, 20 to over-lap the outer faces of the flanges 13 and-l6,-such flanges being slotted, Y as shown at- 21, for the reception of retaining screws 19? and 20, set throug suitable apertures in the top and'bot-tom embers,

and engaging threaded apertures, as 25, int?- of the members 30 and 32.

the instanding flanges 24 of thejrame bars 22. The marginal portions 18 pf the bars 18 are bentt'o fit upon the outer faces of the panel frames 26* and the-marginal portions Screws 28 are set through suitable apertures in the bars 18 screws 28 have been firmly set up.

The font 15 andthe burner carried thereby are of any approved form. The wickraising spindle 39 of the lamp may project outwardly and be lodged in a recess 40 formed in the' frame 32, thus permitting the free movement of the sliding panel 33 and being held thereby against dislodgement from its recess.

The various parts of the lamp are held securely and rigidly togetherby means of the screws set through the clamping bars. Should it become necessary to replace a panel, the screws are emoved from one pair of clamping bars, pe init-ting the ready removal of the damaged panel and the insertion of a new one.

The invention is shown in connection with a top draft lamp, but maybe used ina lamp employing any type of burner or mode of ventilation.

I claim as my invention:

1. In a lamp, in combination, a top section, a bottom section, a set of upright bars uniting the top and bottom sections and having their ends int-urned and bearing, against the adjacent faces of such sections, panels seated against such bars, clamping bars cooperating with the first-mentioned bars for securing the panels, and having their ends inturncd and engaging the top and bottom sections and means for securing the two sets of bars to the top and bottom sections.

2. In a lamp, in combination, a top section, a bottom section, a set, of upright bars uniting the top' and bottom sections and having their ends inturned and bearing against the adjacent faces of such sections, panels seated against such bars, clamping bars for binding the panels to the tirst-mcntioned bars and having their ends inturncd and engaging the outer t'aces ot' the top and bottom sections, and means for securing the various bars to such sections.

3. In a lamp, in combination, a top section, a bottom section, a set of framing bars uniting the top and bottom sections and having their ends inturned and bearing against the adjacent faces of such sections, panels seated against such bars, clamping bars for binding the panels to the framing bars and havin their ends intnrned and slotted and engaging the outer faces of the top and bottom sections, and screws setting through the slots of the clamping bars and in threaded engagement with the framing bars.

4. In a lamp, in combination, a top section, a bottom section, a set of frame bars uniting the top and bottom sections and hav ing their side portions angular in cross-section forming shoulders perpendicular to the planes of the side faces of the lamp, and panel-receiving seats parallel with such side faces, panel-frames angular in cross section for inclosing the panels and engaging the shoulders of t-hcbars, panels seated Within the frames and clamping bars binding the panel-frames to'the frame bars.

5.'In a lamp, in combination, a top section, a bottom section, a set of frame bars uniting such sections and having their marginal portions bent to form panel seats and panel-engaging shoulders, a set of panels ='e11gaging such seats and having instanding 'flanges shdably engaging the upper shoulders and the margins of the top and bottom sections and clamping bars binding the panel sections to their seats.

6. In a lamp, in combination, a top section, a bottom section, bars arranged in pairs detachably uniting the two sections, a frame clamped between the members of two pairs of such bars, and a panel slidably carried by such frame.

7. In a lamp, in combination, a top section, a bottom-section, bars arranged in pairs detachably uniting the two sections, a frameclamped between the members of two )airs of such bars, a panel slidably carried y such frame, and springs for restricting the movement of the panel. v

S. In a lamp, in combination, a body frame, panels fitting the body frame, one thereof being removable, a font seated within the body and having a wick-raising spindle projecting beyond the walls of the body, the. opposite members of that part of the body frame receiving the removable panel having grooved margins forming a slidcway for such panel and one of such frame members having a recess for receiving the wick-raising spindle extending through its said grooved margin.
