DIRIGIBLE LIGHT '2 SheetsSheet 2 Filed May 10, 1945 Fig. 5,

Imventor eson attorney 3 which is welded thereto and in use, the arm 29 is disposed horizontally. The upper cleat 25 is similarly provided with a horizontally disposed arm 21, as shown in Figure 1.

The upper arm 21 is provided with an apertured bushing 28, the bore of which is disposed at a right angle with respect to the arm 2'! and the bushing 29 of the lower arm 26 is similarly provided with a bore. The above mentioned pipe I!) extends through the bores of the

bushings

28 and 29.

As best shown in Figure 1, the threaded bushing M of the nut |3 rests upon the upper side of the bushing 29 of the arm 26 and the bushing M of the nut I2 abuts the lower surface of the upper bushing 28 of the upper arm 21. The bushing M of the nut rests upon the upper surface of the bushing 28 of the upper arm 21. The nuts l2 and I?) are compacted, as above described, after the parts are fitted together in a manner whereby the pipe H) is free to have horizontal turning movements. The pipe I is prevented from vertical sliding movement through the

bushings

28 and 29 by means of the nuts I I, I2 and I3.

As shown in Figure 1, the pipe ||l extends below the lower arm 26 and at the lower end of the pipe H), a sleeve 30 is welded or otherwise suitably secured thereto. Between the bushing 29. and the sleeve 30, a coiled spring 3| is disposed about the pipe ||l.

A collar 32 is slidably disposed on the pipe ||l below the spring 3|. The collar is provided with a set-screw 33 having wings 34, whereby the operator may manipulate the set-screw for disposing the collar 32 in a selected position on the pipe H! for governing the tension or urge of the spring 3|.

The sleeve 39, at the lower end of the pipe I0, is provided with an outwardly disposed arm portion 35, having a pivot-pin 36 which is employed for attaching a lever-link 31 thereto. The lower end of the lever-link 31 is provided with a pin 38 for pivotally attaching an elongated lever 39 thereto.

A push-pull pipe 40 is employed having a lower end which is provided with two outwardly disposed stub-pins 4|. The pins 4| are disposed at each side of the pipe 40 and through the lever 39 for providing a pivotal attachment between said lever and said pipe.

At times when the operator moves the lever 39 up or down, the push-pull pipe 40 is provided with a corresponding movement since the lever-link 31 swings slightly on its pivot 36 to permit the same.

The sleeve 30, at the lower end of the pipe I0, is provided with a set-screw 42 having an inner end which bears against the push-pull pipe 4!], whereby the operator may look the push-pull pipe 40 to the sleeve 30 after he has made a suitable adjustment of the lever 39 for preventing longitudinal movement of the pipe 4|] for purposes later described.

As best shown in Figure 1, the upper end of the outer pipe IE is provided with screw threads 43, having a threaded engagement with a cylindrical member 44.

The push-pull pipe 46 extends through the The bottom of the junction box is provided with two oppositely disposed ears 46 and a bolt 41 extends through and between the spaced-apart ears 46. The bolt 41 provides a pivotal mounting for a link 48, the latter extending downwardly and having a pivotal connection, by means of a pin 49, with a pair of arms 50. The arms 50 are disposed one at each side of the cylindrical member 44, being pivotally connected thereto by means of suitable keepers 5|, as shown in Figure 1.

It will be seen that at times when the handle of the lever 39 is moved upwardly, the push-pull pipe 40 is provided with a corresponding upward movement for raising the ears 46 and the junction box 45 upwardly. Said upward movement applies an upward movement to the link 48 and to those ends of the arms 50 which are pivotally connected to the link 48 for purposes later described.

As best shown in Figure 4, the pin 49 not only provides a pivotal connection between the link 48 and the arms 50, but also provides a mounting for the U-shaped supports 52, respectively disposed at the ends of the pin 49 and between their respecial pairs of

nuts

53 and 54, said nuts being threadedly engaged with their respective ends of the pin 49 for clamping the U-shaped members therebetween. The outer ends of the U-shaped members 52 each support an incandescent light socket 55.

Referring to Figure 1, the socket 55 is provided with oppositely disposed pins 56 which extend through suitable apertures 51 provided through the outer ends of the arms of the U-shaped support for said socket. The pins 56 are provided with screw threads having threaded engagement with the wing-nuts 58 for locking the socket 55 to its support. The other socket is provided with the same arrangement of threaded studs and wing-nuts.

By manipulation of the wing-nuts 58, the sockets 55 may be disposed and maintained in parallelism with each other or inclinedly with respect to each other for causing the incandescent light bulbs 59 to converge their rays of light upon a selected area. For normal use, said sockets are disposed and maintained in approximate parallelism with respect to each other.

As best shown in Figure 1, an insulated electric light cord 60 extends through the push-pull pipe 40. The lower end of the cord is provided with a push-in plug 6| having two

electrodes

62 and 63. An insulator 64 encircles the cord 60, being disposed against the lower end of the push-pull pipe 40. The upper end of the cord 60 is bifurcated, whereby the branch 65 of said cord extends to a socket 55 and the other branch 66 extends to the other socket.

It will be seen that at times when the electrodes of the push-in plug 6| are engaged in an electrically energized receiver socket of an electrical circuit that said energy is communicated through the cord 60 to the sockets 55 respectively for correspondingly energizing the filaments within the bulbs 59, whereby beams of light emanate from the transparent envelopes of said bulbs 59.

In operation, the clamp 8 being secured to the wall or object l1 so that the hooks, 22 of the clamp converge upwardly and the upper clamp l9 being disposed in position with its side walls converging downwardly, the other parts of the device being assembled as above described, the operator then causes the upper cleat 25 to become engaged in its socket I9 and he then moves the 3| since the bushing 29 must be moved downwardly for said purpose at this time.

Then the bushing 29, arm 26 and lower cleat 24 are released, thereby permitting the spring 3| to move the cleat 24 upwardly and into engagement with its socket or clamp I8.

The set screw A is now employed for causing the bushing 29 to become locked to the outer pipe H] at desired times, whereupon the device is in operative position and it will be seen that the device may be readily moved from one location to another as may be desired, provided each new location is equipped with further clamps like the clamps l8 and I9, said duplicate further clamps being secured to the side walls of selected buildings, trees, posts or the like.

In order to move the device from one location to another, the set screw A is released and the arm 26 moved downwardly, against the urge of the spring 3 E for releasing its cleat 24 from the the lower clamp l8, whereupon the device may be moved upwardly for releasing the upper cleat 25 from its holder or clamp l9.

At times when the new device is in position, as shown in Figure 1, and at times when the setscrew 42 is released, the lever 39 may be manipulated for causing the sockets 55 to be swung in vertical directions and to a selected position, simultaneously the set screw A being released, the lever 39 may be manipulated for turning the sockets 55 in a horizontal direction until the beams of light from the light bulbs 59 converge upon work such as a pile of wood to be chopped or the like. At times when the set screws A and 42 are disposed inwardly sufiiciently, the sockets 55 are not movable vertically or horizontally.

From the foregoing description, it is thought to be obvious that a dirigible light constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason, I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as claimed.

I claim:
