To LZ/ lwhom t may concer/n.:

Be it known that l, MARoUs l?. WIELAGE, a citizen of the United States, and resident of Cleveland, inthe county of Cuyahoga have invented certain new and useful Improvements in Dirigible Spotlights, of which l hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the saine.,

The objects of the invention are to provide a simple, eliicient and practical form of adjustable suppo'rtffor a dirigible spot light for a rnotor car, by means of which the lamp can be revolved, upon vertical and horizontal axes, to direct its rays in any required direction. I

This support is so constructed and positioned that the lamp can be adjusted by the operator without leaving his seat in the car, and without exposure to the elements when the sides of the car are enclosed. Also all movements of the lamp can be controlled froni|one operating point, and the lighting switches can also be operated'siniultaneously therewith.

lin this manner all thelnecessary movements required for lighting and operating the lamp can be performed with one hand from within the car.

A further advantage is provided by the' perfect insulation afforded to the conduction wires for the lighting current, which are always enclosed in tubular guides, fwhich prevents frictional contact of the moving parts of the device.

'llhe invention is hereinafter described, illustrated in the accompanying drawings, and specically pointed out in the claims ln the accompanying drawings, Fig. l is a horizontal section of the device; Fig. 2 is a vertical section thereof; `Fig. 3 is a bottorn plan thereof; F ig. d is a transverse section of the lamp support, on line w-a, lilig. 1; Fig. 5 is a transverse section, on line b-b, F ig. lglhig.. 6 is a horizontal section, l

similar to Fig. l, showing a modified clamping means.

ln these views, A represents a standard, supporting the wind shield or canopy of the car. y

B and C are concentric outer and inner tubular shafts which pass through the Serial No. 442,390.

standard, the inner shaft its bearing upon the outer shaft.

D is a bearing in which the outer shaft is secured inl such a manner as to permit free rotation thereof, but to prevent longitudinal movement. This bearing is secured by means of the clamping nut, E, upon the inner portion of the bearing, a shoulder, F, upon the outer end of the aforesaid bearing, apd the outer shaft is secured in the bearing by ineansl of the shoulder, G, upon an elbow, H, upon the inner extremity of said outer shaft, and nuts, ll and J, upon the outer portion thereof. Spring washers, l, l, permit making a close but resilient joint between the moving and stationary parts.

Upon the outer end of the outer shaft is secured the split elbow, lli, or curved continuation of the shaft. Screws, M, lid, se cure the parts together. Upon this elbow is pivoted the lamp, M', vupon the hollow stem, N, to which a bevel gear, O, is secured To the outer end of the central hollow shaft is secured a similar bevel gear, P, so that by revolving. the central shaft the lamp can be horizontally rotated upon its vertical axis.'

Also when the outer hollow shaft is revolved in the bearin the lamp will revolve about the horizonte axis of the aforesaid shaft.

'llo make it possible to revolve these shafts independently from within the enclosure of the car, the s lit elbow, L, or connection H., is secured to t e inner end of the outer shaft.

Revolvably secured in the outer extension, lt, of this elbow, is shown'the short shaft', S, to the inner end of which is secured the bevel gear, T, which intermeshes with the bevel gear, V, upon the inner hollow shaft,

A set screw S', entering a groove, S2, in this shaft, retains the shaft in place and permits adjustment yto malte the shaft loose or tight in its bearing, and prevents the lamp from being moved by the vibration of the car.

A knurled knob, lV, upon the outer end of this short shaft permits revolving the shaft, the inner shaft, and the stein upon which the lamp is mounted, thus enabling the operator to revolve the lamp upon its vertical axis.

Also the outer shaft can be revolved on its horizontal axis without removing the fingers preferably finding 55 with and a shoulder, Z, and nuts,

n V claun as new,

nects the inner tubular shaft with the hol- ,low lamp ste'm, and prevents the abrasion of the insulation from contact with the bevel gears in the elbow, L.v Any ordinary switch, as at X', can be used for closing the electric circuit.

In Fig. 6, a simple form of bearing is shown where the sleeve bearing is dispensed Z,Z,upon the outer shaft, secure it revolvably in place.

Plates, Z2, Z2, can be employed where the standard is made of wood.

This construction is used ard is too narrow to permit of the use of the bearin sleeve.

Havlng described the invention, what ;I and desire to secure by Letters Patent, 1s: y

1. In a dirigible lamp, in combination, a standard, concentric through said standard, provided with an upwardly turned outer end, and a laterally turned inner end, a lamp provided with a hollow stem, vertically pivoted upon the upwardly curved outer end of said outer shaft, and engaging gears upon the adjacent ends of said hollow stem and inner shaft, a shaft within the laterally turned inner end of s aid outer shaft, gearing connecting-the adjacent ends of said last men- -tioned shaft and central shaft, and means. for rotating the same independently of the outer shaft, to revolve said lamp on its vertical axis, the aforesaid laterally turned inner end of said outer shaft serving as an arm for rotating sald outer shaft, and said lamp, on its horizontal axis.

2. In a dirigible lamp, 1n combination', av

standard, concentric hollow .shafts passing through said standard, said outward shaft provided with an upwardly turned outer end, and a laterally turned inner end, a lamp provided with a hollow stem, vertically pivoted upon the upwardly curved outer ends of said outer shaft, and engaging gears upon the adjacent ends of said hollow stem and ashort tubular elbow, Y, conwhen the standextension,

hollow shafts passing' said outward shaft t `centrlc hollow outer and liexible conductors for the lighting current passing through said hollow inner tube and stem.

3. In a dirigible lamp, in combination, concentric hollow outer and inner shafts, said outer shaft provided with an upwardly turned extension at the outer end, and av i laterally turned extension at the yinner end, a lamp pivoted upon of said outer shaft, a shaft revolvable in said inner extension, geared connection between said inner shaft and said shaft in said inner and between said shaft and said lamp, a support and inner-shafts pass, and clamping means on said outer shaft, said clamping means permitting rotation of said outer shaft, but

'the said outer extension through which said outer adapted to prevent longitudinal movement thereof.

4. In a dirigible'lainp, in combination, coninner shafts, said outer. shaft provided with an upwardly turned extension at the outer end, and a laterally turned extension at the inner end, a lamp pivoted upon the said outer extension of said outer shaft, a shaft revolvable in said inner extension, geared connection between said inner shaft and saidv shaft in said inner extension, and between saidl shaft and said-lamp, a support through which said outer@ and inner shafts pass, and clamping means on said outer shaft, said clamping means permitting rotation of said outer shaft, but adapted to prevent longitudinal movement thereof, frictional means forl controlling the rotation of the lamp on its horizontal axis, and frictional means for controlling its rotation on its longitudinal axis. i In testimony whereof, I'hereunto set my hand this 28th day of January, 1921.
