16 Claims.

The present invention relates to marine lamps, and has for an object to provide a lamp of this character in which the principal parts are in the form of metal stampings, and which are adapted to be assembled and disassembled without solder joints, so that in the event of damage to any of the parts they may be replaced, and the lamp will not be subject to separation of its parts from the action of heat and fire. I further propose to provide a lamp structure of strong, rigid and reliable construction, and which will function properly under the severe weather conditions to which such lamps are subjected in use.

1 With the above and other objects in view embodiments of the invention are shown in the accompanying drawin s, and these embodiments will be hereinafter more fully described with reference thereto, and the invention will be finally Z0 pointed out in the claims.

Similar reference characters indicate corre sponding parts throughout the several figures of the drawings.

Referring to the drawings, the marine lamp, according to one exemplary embodiment of the invention, comprises a cylindrical base 10 having an outwardly bent lateral flange 11 at its upper end and having at its lower end an inwardly bent lateral flange 12, provided with upwardly bent substantially semi-circular cam flanges l3 and 14, the ends of which are spaced apart by cutouts 15 and 16 in the lateral flange 12. The cam flanges 13 and 14 are of gradually increasing height from one end to the other, the low end of 50 one flange being adjacent the high end of the other, and are adapted to have a closure and fount supporting member removably secured thereto, as will hereinafter more fully appear.

A rim member 17 of arcuate cross section, 5. adapted to support the lower end of the Fresnal type lens globe 18, is provided at its inner edge with a downwardly extending flange 19 into which the lower end of the globe is snugly fitted. The outer section of the rim member is in th form of a flat marginal flange 26 adapted to seat upon the upper flange 11 of the base 10 and is bent downwardly at its outer edge, as at 21, forming a recess into which said flange 11 fits, the portion 21 extending below the flange 11 to conceal the tie rod ends, hereinafter to be more fully described.

A cylindrical baffle member, carried by the rim member and extending into the base '10, comprises a cylindrical baflie wall 22 provided at its upper end with an inwardly bent lateral flange 23 extending and supported between the arcuate inner surface of the rim member 17 andthe flange 19, the latter being outwardly bent, as at 24, beneath the flange 23 to thereby rigidly secure the bafiie to the rim member. The point of engagement of the baffle with the curved inner surface of the rim member determines the inward spacing of the baffie from the cylindrical base 10, it being understood that this may be readily changed by varying either the angularity or width of the flange 23, or by changing the curve or inclination of the rim member. The lower end of the bafile is preferably given an outwardly offset bend, as at 24, to stiffen it and is disposed 5- in the space between the wall 10 and the flanges 13 and i l in spaced relation to said wall 10 and the lateral flange 12. A series of air inlet openings 25 is provided in the wall 10 near its upper end, and air entering these openings is baiiied by the Wall 22, passing about its lower edge into the interior of the base where it is directed upwardlyby the flanges 13 and 14, being thus subjected to a double baffling action.

The top of the lamp comprises a rim member 26 of arcuate cross-section, disposed in reverse relation to the rim member 17, and having an upwardly bent flange 27 at its inner edge in which the upper end of the lens globe 18 is snugly fitted, the outer section of the rim being in the loo form of a flat marginal flange 28, and which seats against the under side of the lateral marginal flange 29 of an inwardly and upwardly extending annular dome member 30, the flange 29 being provided with a downwardly bent rim flange 31 at its outer edge extending slightly below the portion 28.

A hood portion surmounts the dome member 30, and comprises a cylindrical lower portion 32 and a dome shaped upper portion 33 secured to said lower portion by an interlocking curled joint 34. A centrally apertured dome-shaped bafile 35 is secured to the lower end of the hood, and in order to facilitate assembly the hood member 32 and baffle 35 are secured to the annular member 30 as shown in Figs. 8 and 9. Before assembling an inwardly bent bead 36 is formed near the lower edge of the member 32 against which the outwardly flared lower end of the bafiie member 35 is engaged, the opening in the member 30 being of such diameter as to permit insertion of the downwardly extending end of the member 32 as shown in Fig. 8. A double crimp is thereupon imparted to this lower end portion, as shown in Fig. 9, the upper portion of the crimp being forced outwardly to engage the upper side of the member 30 as at 3'7, and at the same time extending inwardly to clamp the lower edge of the baffle member against the bead 36, and the lower portion of the crimp being forced outwardly as at 38, to clamp against the under surface of said member 30.

A series of air outlet openings 39 is provided in the cylindrical portion 32 of the hood, passage of air to these openings being bafiled by the baffle 35. The upper portion 33 is also provided with a series of air openings 40 which are exteriorly bafiied by an overhanging cap member 41 surmounting the hood and secured thereto by clip 42, which also secures a ring handle 43 to the top of the structure.

The flange portions 11, 20, 28 and 29 are respectively provided with series of spaced holes 44, 45, 46 and 47, the holes 44 and 45 registering with each other and being vertically aligned with the holes 46 and 47, which also register with each other. A series of vertical tie and guard rods 48 are inserted through these holes and are adapted to secure the upper and lower portions of the lamp together and at the same time tightly clamp the lens globe 18 between them. The upper ends of the rods are provided with slotted heads 49 and the lower ends are threaded and engaged by nuts 50, these nuts being seated and concealed in the annular recess formed by the rim flange 21, and being held against rotation by engagement of two opposed sides of their hexagonal peripheries with the wall 10 and the flange 21.

Tie rings 51, preferably two in number, are secured to the lower ends of two of the rods 48, and for this purpose a metal clip 52, bent about the ring to form a bearing and having its end portions perforated, is engaged upon the lower threaded end of the rods 48 and secured by the nuts 50. These particular rods may be slightly longer than the others to facilitate mounting of the clip, and may be readily interchanged with the other rods to position the tie rings at the most rib 55 in inwardly spaced relation to its edge, this rib being of greater height than the cam flanges 13 and 14 and having its outer wall of cylindrical form and adapted to fit snugly within the circular opening provided by said cam flanges. At diametrically opposed points the rib is indented and the metal is pressed outwardly to provide a pair of lugs 56 and 57 adapted to overhang the upper edges of the cam flanges 13 and 14, the height of these lugs being substantially the same as the intermediate portions of the flanges. In placing the closure in the base the lugs are inserted through the cut-outs l5 and 16, and thereupon the closure is turned, causing the lugs to ride upon the upper surfaces of the cam flanges to points where their increasing height causes the closure to be held tightly with a wedging action. An air-tight closure is thus secured, and at the same time the closure may be conveniently removed and replaced.

The oil fount 58 is removably secured to the closure bottom 53, and for this purpose a plate 59 is secured to the bottom, as by flanged over eyelets 60, and is provided with a plurality of spring clips 62, suitably curved to embrace a rib 63 formed on the fount.

In Fig. 11, I have shown a modified form of the invention in which a dome shaped top 64 is provided with a marginal flange 65 having its edge bent downwardly as at 66 to receive the flange 28 of the upper globe lens supporting rim member 26 In this embodiment the rim member 26 is provided with a globe engaging flange 27 similar to the flange 27 of the first embodiment, and is further provided with a series of air outlet openings 67. An annular cylindrical baffle member 68 is disposed within the rim member and is provided with a lateral flange 69 extending between the flanges 65 and 28 and having holes '70 through which the tie rods 48 are engaged, registering holes '71 and 46 being also provided in the flanges 65 and 28 It will be seen that the baffle is disposed in spaced relation about the flange 2'7 so that the air is doubly baflied in passing from the interior of the lamp to the outlet openings.
