LAMP FOR CYCLES.

SPECIFICATION forming part of Letters Patent No. 586,348, dated July 1.3, 1897.

Application filed December 7, 1896- Serial No. 614,743. (No model.)

To @ZZ whom it may concern:

Be it known that I, LEwIs J. ArWooD, a citizen of the Uni ted States,residing at Vaterbury, in the county of New Haven and State of Connecticut, have invented an Improvenient in Lamps for Cycles, of which the following is a specication.

This invention is made for lessening the risk of the llame being extinguished by currents of air that are intensified in their action upon the flame by the rapid movement given to the lamp as carried on the cycle, and at the same time for allowing the parts to be detached sufficiently for removing accumulations of smoke or oil and for holding the parts lirmly together when in use.

Wfith the aforesaid object in view the lower portion of the lamp-body is perforated for the free admission of atmospheric air to the flame, and an annular wind-guard is applied around within the body of the lamp over the perforations and around the lamp-burner, so that the currents of air are supplied within the lamp-body closely adjacent to the inner surface and cannot pass with force toward the llame, and there is a draft-cap around the Wick supported by the body of the lamp-burner and having numerous small perforations through which air is allowed to pass near the llame, and a deiiector is held by this draft-cap so as to shield the lower edges of the name where the same rises from the wick. The reflector sets at its bottom edge within the body of the lamp, and it is held by a spring connected with the bach of the reflector and passing up into the top opening through which the products of combustion pass, and as the reliector is pressed back to position the spring not only holds the reflector itself but also is held into the body of the lamp by the metal at the back of the opening in the body, and the removable upper portion of the lamp-body is made for allowing the free escape of the products of combustion and for preventing currents of air passing into the lamp.

In the drawings, Figure 1 is a verticaly section of the lamp. Fig. 2 is a sectional plan through the body of the lamp with the front glass and frame swung open. Fig. 3 is a sectional plan representing the locking device for the burner. Fig. 4 is a detached sectional view of the removable lamp-top, and Fig. 5 is a side view of the reflector detached.

The lamp-body A is cylindrical, and has a back A', that is closed except at the perforations 3, and there may be side glasses B in this lamp-body. The front glass Cis received into a conical rim D, that is hinged at el to the front of the lamp-body, and theA spring 5 catches over the front edge of the rim of the glass to hold the same when shut.

The reservoir or fount E is to be of any desred size and shape, and upon the top thereof is screwed the burner F, that is provided with a wick-tube 6 and with a wick-raiser 7, and in the opposite sides of the burner in the sheet metal thereof are projections or lugs 8, and projecting downward from the lampbody A, at an opening therein, is the air-distributer G, which is conical in form and lirmly connected at its upper edge to the lamp-body at the opening therein, and this air-distributer is made with numerous small holes, and there is a hollow bead 9 at the lower end of the air-distributer and notched at opposite sides, as seen at 2 2 in Fig. 3, for the passage of the lugs 8 upon the lampburner E, and there are stops l0 within the hollow bead 9 at opposite sides thereof, so that after the burner has been entered through the opening in the bottom of the lamp-body with the lugs 8 in the hollow bead 9 the reservoir E and burner are given a quarter-turn to bring the lugs S against the stops l0 to arrest the further movement of the parts, and it will be apparent that the lamp-burner can be inserted in place, with the wick-raiser shaft 7 projecting either at one side or the other side, because there are two lugs and two notches in the hollow bead, and the lamp can be introduced and turned with the wick-raiser shaft either to the one side, as shown by the full lines, or to the other side, as shown by the dotted lines, thus giving easy access for regulating the llame according to the manner in which the lamp may be supported upon the cycle. v

Rising 'from the ratchetcap or upper plate of the burner F is a draft-cap H of a size to set closely into the opening in the bottom of the burner at the top of the air-distributer G, and this draft-cap has legs 11, by which itv IOO is connected with the burner and supported at the proper height around the wick-tube 6, and the holes in this draft-cap are numerous and small, so that the air passing up from below the ratchet-cap to the flame will be subdivided and will not cause the flame to iiiclrer or smoke.

Rising from the top of the draft-cap H is a deiiector l, having straight plates, one at each side of the wick-tube and protecting the base of the flame, and the end connections of these plates are depressed or notched, so as to give space for the flame to spread.

Through the lower part of the body A and around the aiikdistributer are holes 12, in one or more rows, for the free admission of air into the lamp-body, and the annular1 deflector K is connected at its inner edge at the junction of the air-distributer and the lamp-body, and it projects out over the holes 12 and at a sufficient distance from the interior of the lamp-body for the air to pass freely between such deflector and the lamp-body and rise into the body for supplying fresh-air to the flame, and at the same time the annular deilector prevents currents of air passing direct to the iame, so as to cause the iiame to flicker or to smoke.

The upper end of the air-distributer is preferably turned over to connect the annular deflector K, lamp-body, and air-distributer together.

At the top of the lamp a cylindrical windguard 13 is connected at its base to the lampbody, and around the same and flaring outward is a perforated base 14 for the cap L, which is composed of the conical portion 15, having tongues 16, extending upward to the top plate 17, the tongues being riveted to the top plate, and this top plate has a cylindrical hanging ange 1S surrounding the openings between the tongues 1G, and the top plate 17 is perforated and provided with a conical deflector at the under side, connected at the middle portion to the top plate, so that there is an air-space between the conical defiector and the perforated top plate for allowing the products of combustion to pass around the conical deiiector and escape through the perforations, and this deflector 19 prevents currents of air blowing down into the lamp either through the openings in the top plate 17 or through the openings between the tongues 16. The cap L is connected to the perforated base 14: by lugs or projections 20 near the top edge of the perforated base 14, passing into the hollow bead 21 around the bottoni edge of the conical portion 15 of the cap, such hollow bead being notched at one side to allow one of the lugs 2O to pass into the same after the hollow bead has been placed overy the other lug, and by giving the cap a partial revolution the parts are locked together.

The reflector M is adapted to set within the body A at the back portion, there being a space around the reflector for air to pass in through the perforated back A of the lampbody and escape into the interior of the lamp- Athe annular deflector K, and there is a spring 22, fastened at its lower end to the back of the reflector, and its upper end comes above the top edge of the reflector and is bent up as a latch. The shape of this spring 22 when not under pressure is indicated in the detached view, Fig. 5, and when the reflector is put in place at its bottom edge the upper end of the spring 22 comes into the central opening of the wind-guard 13, and by pressing the top part of the reflector back it comes beneath the latch end of the spring 22, and

hence this spring holds the reflector back inposition and is itself held in place by engaging the metal of the body A adjacent to the wind-guard 13. In this manner the reflector is held rigidly in position, and it can be easily removed by the thumb or finger applied to the-upper end of`the spring 22.

I claim as my inventionl. In a lamp for cycles, abody of sheet metal extending across above the reservoir and having an opening through it for the wick-tube and surrounding parts on the removable reservoir, and perforations through the sheet metal around the opening, in combination with the annular deflector above the said perforations, and an air-distributer adapted to extend down around the burner upon the reservoir and passing at its upper end through the opening in the lamp-body and turned over to secure the annular deliector to the lampbody, substantially as set forth.
