(01." aia-n n) "This invention relates to improvements 'in dirigiblelightarand more particularly dirigible lights adapted for use on automobiles and other automotive vehicles, Whichlights are commonly` 5 called spotlights. The present invention is in the nature of an improvement on such type of light showninmy '3o-pending application 253,820 filed February 13, 1928,A now Patent 1,906,489, issued May, 1933. Y

,The type of dirigible lightv rei-erred to comprises, in its broadest aspects, `an outer head housing on which is rotatabiy mounted about one axis a lamp casing; a handle housing at the .op-`

posite or inner end, the head and handle housings 5 beingrigidly united to rotate yin unison about cliilerent axis, by a hollow tubular connection; an operating handle rotatably mounted on thev handie housing; an electric control switch on the.'

or backlash between the movable parts and to 30 compensate for Wear to thereby prevent looseness Vor rattling when the light is in service.

An object of the present invention is to provide a dirigible light of the type hereinbeore referred to and vpossessing all of the desirablechar- 35 acteristics thereof, the present improvement being such as to reduce the number of necessary parts to a minimum Without any loss of advantages or functionsto the end that the cost of material and labor of assembly maybe greatly f 40 reduced.

Another object of the present 'invention is to provide in a. dirigible light of the type'indicated, an eflicientrelectric switch comprised of `few parts with low cost of manufacture and suchthat the switch may be readily applied tothe handle housing or removed for repairs or inspectionwithout disturbing or disassembling any, vof the other parts.

Still l another object of the invention is yto providea supporting and attaching bracket for v the light, which, bracket is specially formed to adapt it as a drill guide in boring the usual hole through the automobile superstructure or the H55 Llike forf receiving th'egtubular connection, to

'corresponding to the` .section lines 3 -3 and 4Q-4 On `its upperface, as shown lin Figure'msaidfsechorizontal axial alinement the recess 20,l the thereby minimizethe cost ofapplicationoif the light. L

ln'saiddrawings,` :'10 denotes a corner post .or other` part 'of the super-structure of an auto,- mobile or other automotivevehicle` tofwhich my improved lightY ist adapted to-.lbe attached, al-

- though as will be understood by those skilled in the-.art the light sapplica'ble tooutsidejinstalle ments by suitable modification `of theattaching brackets. TheV improved-light, as shown, Vcomprises a head housing A; 1a `handle' housing :335;- a tubular connector C rigidly assembled with both of the housings A and-B; a lampcasing or shell D; an operating vhandle E; together with suit- 85 y vable attaching brackets'sWitch and` other parts v hereinafter described. i

The. head housing .A is preferably in the form of a casting. havingY two main sectionsall and 12 ,"disposedapproximately at right angles ,to each 90 other, the housing A being hollowed out, as clear from Figure ,1.` `Thesection 1.1, disposed vertical,-

lyas shown inFigure 1;.has-an interior vcircular recess 13 and an inwardly `'extending ange or webigthe latter having ajournal` hearing 1.5. 9

tionll :is formed with acircular'recess iii-.into which extends, radially, a' stopor limiting lug 117 .for the purpose hereinafter described. .In axial `alinement with the recess f1.3 .atthe bottom of 'the secured tothe corresponding `or-fofli-ter endof the tubular connection C, as showninFigure'l In housing A is provided, at its outer end, with an opening 22 of the same or slightly larger diameter than the recess V20, said opening 22 being adapted to be closed or covered by a similar, light sheet metal snap cap or closure 23.

Rotatably journaled. in the bearing 15, is the shank 24 of a bevel gear 25, the gear 25 being of larger diameter than the shank 24 and providingv 18. Bearing against theupper end ofthe gear Y shank 24 is the lower 'flat face of a saddle or block 28, the upper face of which is conformed to t the lamp casing D. Said block or saddle 28 has a hollow upstanding hub 29 preferablyv of non-circular cross section extended' through a correspondingly shaped opening in the shell D. On the interior of the shell D is a specially shaped spring washer 30 having 'a horizontal section 31 against which seats the head 32 of an axially perforated bolt 33 that is extended loosely down Vthrough the saddle block 28 and threaded within the shank 24 of Y the gear 24-25. By screwing the bolt 32-33 tightly into the gear 24 25, it is evident that the casing D will vbe tightly clamped between the washer 30 and block 28and the latter in turn tightly clamped to the gear 24-25. c

On its underside, the block 28 is bored to tightly receive therein a pin 34, the lower end of which works within the recess 16 in the upper face of the section 11 of the head housing A, it being obvious that said pin34 will be limited in its rotation by engaging the radial lug 17, best shown in Figure l5, so that the lamp casing will be limited to rotation slightly less than 360. As shown in Figures 1 and 5 thepin 34 is so located that it is partially received within a shallow groove 35 in the hub of the gear 24-25 so that said pin also functions as a key or spine between said gear and the saddle block 28, to insure their rotation in unison and in both directions without danger kof the bolt 32-33 becoming loose or unscrewed.

With the construction so far described, it will be observed that not only will the lamp casing always be rotated in unison with the bevel gear 24-'25 but that,-because of the Yspring 27, the saddle block will always be maintained taut against the upper bearing face of the section V11 of the housing A, thus eliminating any looseness and automatically compensating for any wear which may occur on the two relatively rotating surfaces.

Where the light is mountedfor so'called inside control, as shown in Figure 1, a supporting Yattaching bracket of the type indicated at 36v will be employed, the same having laterally extended anges 37-37 by which it may be attached by screws to the post or other -support 10. The bracket 36 has a relatively elongated, horizontally disposed, cylindrical section 38within which is preferably cast a thin sleeve 39 of steel or other suitable hard materialY and ofan accurate inside diameter to function as a guide for a drill in boring the hole `40 through which the tubular conneet-ion Cis ultimately passed. Inapplying lights of the typeA disclosed, particularly to the corner posts of automobiles, extreme accuracy is required -in drilling the hole forgthe tubular connection,

' since the corner posts are nowof relatively small Said gear 24-25 with the spring 27 as-A Windshield giassvetc. in drimng the hole, it being truey as to certain makes of automobiles that there is not more than a possible leeway of g or 1/8 of an inch in centeringA the hole to be drilled. Heretofore, it has been customary to rst spotthe drill hole by employing a temporarily applied drill thin flange overhanging a reduced section 4 2 on the inner end of the housing A so as to provide an additional bearing support for the housing A in its'rotation about a horizontal axis.

On the inside of the post or :other support 10, is a second inside bracket 43 having diametrically disposed'arins alsoA adapted to be secured by screws. Said bracket has a split hub bearing section 44, the friction between which and the tubular connection C may be adjusted by means ci the screw bolt 45. To limit the rotation of the tubular connection C about the horizontal axis and also to prevent the same irom working outwardly, a split collar 46 is frictionally. secured thereto,Y as by means of an adjusting screw bolt 47, said collar having a shoulder 48 cooperable with a shoulder 49 on the bracket 43 to limit the rotation, as will be understood.

The handle housing B is preferably in the form ci a casting having a main horizontal section 5D split and secured to the tubular connection C. as by the adjusting screw` bolt 51'. Depending Vfrom the horizontal section 55 is a hollow bearing section or extension 52, the latter having an interior annular recess 5'3 providingV a shoulderf54 near the bottom thereof. The tubular connection C is extended within the housing B and contains within it a hollow shaft 55, the latter carrying a bevel gear 156 at its outer or left hand'end, as

viewed in Figure l, which gear meshes with the gear 25. AThe righthand endof the shaft 55 is extendedinwardly of the tubular connection C and made of square or other non-circular cross section so as to receive thereon a bevel gear 56, the latter rotating with the shaft but being slidable or adjustable lengthwise thereon. Said gear 56 has a journal section 57 rotatable in acorre- To compensate for inaccuracies of manufacture and totake up wear, one or more shims 62 may be interposed between the upper end of the handle proper E and the lower end oithedepending section 52 of the handle housing. To maintainv the parts taut-and to prevent backlash, a'coilspring 63 is slipped over thevshank 59 and interposed between the gear 58 and the'shoulder 54, it being evident that said spring will normally urge the gear 58 upwardly into tight mesh with the gear 55, To permit assembling of the gear 5B and its shank in the housing B, the -latter is Vprovided at the top thereof with an .opening 54 of diameter equal to or slightly larger than that of the gear 58, said opening beingl normallyrclosed by'a sheet 'threaded into the lower end of theV gear shank 59.

width (see Figure 3) to receive end wise'therein,`

two correspondingradially extending lugs 68v and 69 of a lead-in block 70 made ofbakelite or other suitable insulating material. By reason' of the different size slotsand-lugs 66, 67, 63 and69, improper a'ssembly of the lead-inblock within the housing islther'eby prevented. SaidleadLin block is of generally y*circular form and centrally thereof has moulded therein a preferably brass com'- bined'binding post, bearing and contact element 71, the` inner end of which is enlarged, as indicated at 72, and centrallyapertured to receive the stripped end 73 -of an electricalwire or conductor 74, the same being held by a binding screw 75. TheV other or righthand end of the element 71 is of `reduced diameter, as indicated at75,

. and forms a journal bearing for an insulated rotor or knob '76; To one sideof its center,' theV lead-in block 70 has also moulded therein a metal contact 77 to which is soldered the stripped end -78 of theilead-in wire 79 which,.as shown in Figf ure 1, is entered through the -inner end of theY Yhousing B and fixed to the tubular connection C by'a suitable ring clip 80. As will be understood, said conductor 79 leads toa suitable source of electricity," as for instance, the battery of the. car. Therotor 76"is moulded with a specially shaped recess, best shown in' Figures 2 vand 4. Said ,rev

cess comprises two spaced circular portions y81---81 connected Vby atransverse recess 82 to thereby receive a specially formedspring, which comprises twocoils' 83-83 with a connecting section 84 therebetween. The'free end of one -of the coils 83 is so positioned as to .be brought into Vand'out of contact with the contact element 77 from the `latter through the conductor 7B-74, Ywhich in turn is passed through the shaft 55 and thence through the bolt 32-33 into a socket shell 86 in the lamp casing where its other stripped end is secured to a contact 87'mounted in a spring influencedinsulated washer 88. Said contact 87 is adapted to engage the usual contact atthe inner end of a lamp bulb 89. Y

The rotor '76 has an inner annular enlargement 90, thereby forming a` shoulder so that said rotor is held in assembled position by `means of a sheet metal capV or ferrule 91, the latter in turn being secured Yto the housingB by two screws 92-92, which also havetheir inner ends entered in recesses 93-93 in the lead-in block so as to also retain the latter in proper position within the housing B. To limit the rotativerrnovement ofA the. rotor 76, the latter is provided with an arcu' ate recess 94 within which is extended a lug 95 formed integral with the lead-in block 70, the angular throw being limited,.as will be evident from an inspection of Figure 4. With the construction shown and referring particularly toFigure 2, it will be evident that'the spring 83-5-84 normally urges the rotor 76 outwardly or toward the rightV and will thereby create sufficient friction between `has its inner end of reduced sectionfas'shown vat 96, the same being interiorly threaded to re.-

Next, the vgear 24-25 with the 'spring 27v assembled thereover is" entered vertically through the opening 18, the gearl Vbeing pressed to the Vright during this operation sufficient to permit clearance in entering'rthe gear 25. After thelatter is in place, the gear 158 isrreleased and will be forced into mesh by the spring 20. The saddle` blccl; 28, casing D, washer1391andbolt 3.2Vv are then brought to'gether'and secured by the bolt, as will be understood.v The conductor 74 is then vso ybulb withjresp'ect tothe reput inplacearld suitably connected to the contact 87` withinthe'casii-ig D,4th'ese parts constituting the head end assembly ready'fer shipment.
