20 denotes an inner toothed clutch member slidable on the inner end of the tubular shaft 18 and held, as at 2l, for rotation therewith, said inner clutch member having a cylindrical easing Q2 inelosing a pin head 23 fixed on the inner end of the tubular arm f1. The easing 22 has a series of circumferentially disposed apertures adapted to receive pins 24 carried by the head 23 and the pinhead 23 and easing 22 are normally in terlorked by' the pressure or expansive torce ot' :t spring 2.3 disposed within the casing 22 and hearing against the pin head 23.

It is therefore possible to oscillate or wigwag the lamp or lock it in an adjusted position through the medium of the pin head 23 and the casing 22 constitute ing locking means for holding the yoke in adjusted position relative to the head 6 of the arm 4. By oscillating the handle 27 the lamp housing 13 may be wigwagged or turned in a desired direction relative to its supporting yoke, and the various movements may be accomplished by simpl)r shitting the handle 27 longitudinally of the shaft 2U and turning it in the desired direetion.
35 denotes a detachable closure plate l'or the outer end of the cylindrical yoke head H and the inner fare ot said plate is provided with a block of insulation 3G having pins 37 adapted to extend into a series of eireumi'erentiall)r disposed openings or apertures 3H in the side oiE the wheel 30. A spring 3) n'iaintains the wheel 3i) normally in engagement with the pins 37, said pins and the block of insulation 3G serving as a pin head somewhat similar to the pin head 33, and constituting means for locking thel'iandle shaft 2G against accidental rotation. liesides placing the handle 27 in interlorked engagement with the shaft 2G to rotate the same, it is netessary to shift the shaft 20 longitudinally oi' the Yoke shaft in order to l more the wheel lit) out of engagement with the pins 37.
Considering now the elet't'rieal rennertions and the eontrol tor the inenndest-ent lamp 15, said connections` and controlling mechanism are disposed so as to prt-rent short circuits and not interfere with the universal movement of the lamp.
40 denotes an insulator in the sleeve portion 17 of the easing 12 and extending through said insulator are leading-in wires 41 to the incandescent lamp 15` said Wires extending between the Wall of the housing 13 and the wall of the retieetor 11. The outer ends of the lead-in wires -1'1 are connected to insulated disks 4 2 and nornialli' engaging said disks are brushes ,4:3 supl'iortetl by an insulator L11. The easings 11 and 12 have detachable side plates so that the parte Within said casings can be readilyY assembled.
1G and 47 denote conductors connected to the brushes 43 and extending through one of the, yoke arms 10, the conductor 4G being connected to a binding post 48 supported by and insulated from the reduced end 7 of the Htl tui
itin
`Yoke head 8. The conductor 47 extends to the block of insulation 36 and is connected to a resilient switch member 49 movable to and from a stationarv switch member 50, carried by the block ot insulation. The stau tionary switch member 5() is connected by a eonduetor 51 to a binding post 52 on the end of the head 8.
53 denotes an insulator in the head G of the arm 4, and on that faee of the insulator confronting the reduced end 7 of the yoke head 8 are concentric rings 54 and 55. These rings are engaged by brushes 56 carried by the binding posts 48 and 52, and the rings 54- and 55 have binding posts 57 for leadin Wires 58. The Wires 58 extend through a suitable insulator 59 in the head 6 and are adapted to be oonnected to a suitable source of electrical energy not shown).
(to denotes a reciprocable switch rod con centricall y of the handle shaft Q6, the Wheel and the inner clutch member 34, said switch rod having the outer end thereof normally engaging the resilient member 49. The inner end of the switch rod has a cylindrical enlargement Gl in the clutch member 3l and there is a pin and bayonet slot connection (32 between the clutch member 31 and enlargement tl so that the switch rod G0 can be locked in adjusted position. The enlargement (31 has a knurled knob or handle (23 so that it may be easily rotated and reeiprocated, and a pin G4 in the switch rod G0 prevents :u'eidental withdrawal of the switch rod from the handle shaft 2G.
lt is non' apparent that through the medium of theI disks, rings, brushes, switch and conductors thaty the incandescent lamp may he continuously illuminated or flashed, iircspcctiw of the position of the lamp and darin;l any adjustment thereof. A hand gripping the handle 2T can easily and quickly make desired adjustments, and at the same time control the illumination of thc lamp.
llet'crencc will nonv be had to Figs. 8 to 1l) inclusive, illustrating a modified form of signal lamp. and more particularly the lockingl mechanism for controlling the oscillation of the lamp in its yoke.
(ttl and (3T denote casings similar to the casings 11 and 1Q of the preferred form of construction and in this modified form we place a portion of the lamp actuating mechanism and a portion of the electrical connections in the casing G7. In other Words, We combine thil elements 33, 40, Lt2 and elfi of the preferred Form of construction Within the casing` GT, use one of the arms 10 for the poner transmission member, and the other of said arms 10 for the conductors 46 and 1T. This leaves the casing 68 and the set of arms 9 so that We may install the modified form of locking device.
(1S denotes a trunnion or a gudgeon of the lamp 13 and said trunnion extends into the casing G6 and is provided With a toothed wheel (i9. Engaging the toothed Wheel 69 is a spring pressed latch or detent 70 pivoted within the casing G6 and connected to the end of a able or flexible rod 71 that extends through one of the tubular yoke arms 9 into the yoke head 8. In the yoke head 8 the cable or rod 71 is connected to an angular crank T2 on the outer end of the switch rod and said crank is adapted to be sprung over a lug 73 on, a retaining Washer 74 mounted in the yoke head 8. The retaining Washer 74 is notched, as at. 75, so as to facilitate assembling the elements within the yoke head S, and with the crank 72 sprung over the lug 73. the latch or detent is held in a retracted position, thus permitting of the lamp housing 13 being freely adjusted. By
partially turning or rocking the switch rod (it), the latch or detent 70 may be released to engage the toothed Wheel (59 and hold the lamp in an adjusted position.
thile in the drawings there are illustrated the preferred embodiments of our invention it is to be understood that the structural elements are susceptible to such variations and modifications as fall Within the scope of the appended claims.
What we claim is:-
