l To all whom 'it may concern:

Be it known that I, HORACE lV. BEEBE, a citizen of the United States,l residing at New Haven, in the county of New Haven and State of Connecticut, have invented aim as in the retired position. Fig. 3 a brokenv top or plan view showing the disks in their retired position. Fig. 4 an enlarged sectional view of the lower portion of the tube showing means for operating the rod. Fig. 5 a sectional view on the line (r-b of Fig. 1. 1 This invention relates to an improvement in vehicle lamps, and particularly tol lamps in which a f dimmer is arranged between the burner and reflector, and adapte-tl to be spread so as to temporarily suppress lthe ae- 9 tion of the reflector, and is an improvement on the invention shown and described in Letters Patent No. 925,676. In the construct-ion shown and described in the above patent, a spring was required to hold the 5 parts of the disk in an open position.

The objeetof this invention is to provide the tube in which the dimmer slides with a cam groove, and the dimmer with lingers to engage with the edges of the groove so that 3 the dimr'irwwill be positively opened, and he invention consists in special neans for operating the dinnner as willbe more fully hereinafter described and particularly recited in the claims.

In carrying out my invention IA employ a lamp body 2 of usual construction including a fixed reflector 3 and a burner 4. In rear of the burner 4 is a tube 5 which projects down through the bottom of the lamp. The rear of the tube 5 is cut away forming cam surfaces 6 and 7, while in the front of the tube is a slot 8 forming curved cam surfaces 9 and 10. Within the tube is a verti- 4 cally movable rod 11, and hinged to this "1 `rod are tw'o semi-circular leaves 12 and 13 like the leaves in 'the patent before mentioned. Secured to the forward face of each leaf is a linger 14 and 14, which fingers enter the slot S and ride over the cam surfaces 9 and 10 and so that as the rod is raised, the leaves will be spread, as shown in Fig. 1 of the drawings; and when the rod is depressed these fingers riding in the grooves will cause the leaves to be folded as shown in lfig 3 of the drawings. The rod 11 is maddarger at its lower end than at the upper er1/d to which the leaves are at-l tached, the main portion of the rod closely fitting the tube and giving sufeient weight to cause the rod to normally remain in its lower position and so that the leaves will be normally held in a folded position. As a matter of convenience the portion 16 of the tube which projects below 'the lamp casing Will be made separate from the upper portion 15, and the parts will be threaded together so that they will be separated. The .upper part will be provided with a flange 17 which rests upon the bottom of the inside of the casing, and the lower part of the tube will therefore hold and clamp the upper part in place.

Formed as a part of, or secured to the upper part of the lower portion 1G of the tube is a housing'lS carrying a roller 19 over which a cord or wire 2() will pass into engagement with the lower end of the rod 11 and so .that a pull upon this cord or wire 20 will lift the rod 6 and cause the disks to open. lYhen this cord or wire is released the rod will fall by'gravity and thus fold the leaves. This cord or wire 20 may lead through a pipe 21 or otherwise to any point in the vehicle convenient to the. operator. If a pipe is employed the pipe 21 will lead to a cylinder 22 in-which a slide 23'is arranged, this Slide' being connected to the end of cord 2O and in the cylinder I arran a the Wire or spiral spring 24, the tendency of whic, is

lo draw the slide downward. This cylinder is preferably arranged adjacent to the steering post and a convenient handle connected with the slide so it maybe pulled upwardf this pull upward lifting the rod 11 so as to spread the dimmer. l/Vhen it is released the spring 24 will act to draw backv -theslide 23 so that the rod 11 may byfits own weight drop in the tube and fold the dimmer.

As in the patent before referred to, the disks are spread between the burner and reflector whenever it is desirable to temporarily suppress the act-ion of the reflector as when two vehicles are approaching each other. To spread the reflector 41t is only necessary to pull upon the wire or cord 20,.

and then when the necessity of suppressing` the action of the reflector is passed, releasing.;- the wire or cordwill allow the rod to drop and draw the disks into their retired posit-ion, a position in a line, directly behind the burner so that no shadow is caused by them.

I claim i l. In a lamp, the combination with the burner and retlector,`of a tube located between the burner and retlector, said tube being` formed with a slot in its ,front face eX- tending downward on opposite sides, a vertically movable rod in Asaid tube, and two semicircular vdisks hinged so said rod, said disks being provided `with.v lingers projecting into said slot. l

2. In a lamp, the combination with a burner and reflector, of a tube located be,

tween-the burner and reflector,V said tube formed on itsrear face'with cam-surfaces and with a groove at the Yfront extending down on opposite sides also forming cam surfaces, a vertically movable rod v in said tube, two semi-circulzu disks hinged to said rod and provided with lingers ext-ending into saidV groove, a roller mounted adjacent. to the tube below the. lamp, and a wire or cord passing over said roller and secured to the lower end of said tube whereby said tube -inay be raised.

. 3. Inl a lamp, the combination with a burner and reflector, of a tube vlocated be tween the burner and reflector, a rod mounted in said tube, se1ni-circular disks hinged to said rod and adapted to be spread above the burner, a cord secured to the lower end of said rod, a pipe through which said cord lH.
