ADJUSTABLE LIGHT FOR INSERTION IN THE HULL 0F BOATS Filed NOV. 30, 1948 2 $HEET$'$HEET l FIEl FIG; 2, JOHN 1522?)?- April 15, 1952 J. F. MORSE 2,593,171

ADJUSTABLE LIGHT FOR INSERTION IN THE HULL VOF BOATS Filed Nov. so, 1948 2 sums-mm 2 INVENTOR. JOHN F. MORSE Patented Apr. 15, 1952 OFFICE ADJUSTABLE LIGHT FOR INSERTION IN H HULL OF BOATS a John F. Morse, Hudson, Ohio V 1 The present invention relates to improvements in lighting installations for boats and particularly for craft of the power-operated type.

Boats-of this type have usually been-provided with searchlights located at some position above the deck of the vessel as the sole means for illuminating the channel and docking area'ahead of the boat. When'making a night landing the searchlight will throw areas not in the direct path of-the light rays in absolute darkness and this is particularly objectionable in night navigating because the deck of the vessel casts a heavy shadow over the water immedately ahead ofthe boat and the reflections from the deck in terfere with the clear vision ahead.

The present invention has as its object the construction of a new form of lighting installation which will reduce the hazards associated with docking, craft after dark or navigating at nightin narrow and dangerous channels or dark Waterways. The invention therefore not only consists in the construction of the light elements per se but also in the combination of the light elements with the hull construction, particularly at the prow of the boat.

Application November 30, 1948, Serial No; 52,680 2 Claims. (01. 240-26.)

ferred form of the invention is disclosed hut it will be understood that changes, modifications and improvement therein may be: made without departing from the principles of the-inventionas set forth in the claims.

In approaching the dock at night, the pilot will turn on the lights and the area of water ahead of the boat and the piling, docks and berth for the boat will be brightly illuminated by a clear flood of light issuing from below the deckand beneath the eyele /e1. The deck of the boat is not illumi nated as is the case with the ordinary'searchli'ght and, even in rain or haze, the objects ahead stand out in clear relief. The installation is also useful in navigatingthroughjtreacherous water or narrow channels for-floating logsQbuoys and other articles on the waterare clearly visible. Practically no light isr'efiected back to the-pilot even from the smoothest waterand objectson the waterwill stand out in bold relief, beihgeven more readily visible than-in daylight. The light shown and describedherein also makes an attractive and decorative addition to all types of watercraft. The invention shown and described-hei-einis a very substantial and efiective aid to night boating; relieving much of the strain upon the pilot an'd reducing the risks attendant upon night navigation. The present applicatio isin the nature of an improvement upon the inventiondisclosed in applicantsprior application on Docking Lightj" Serial No. 663,518, filed .May 9, 194.6, mm Patent No. 2,504,215 g f v ,In the 'drawings andiri the description accompanyingthis application thejbest known and pro- I Fig} 4 is a diagrammatic View oftlie-prow of a boat showing the -manner' i which" -the light rays are projected onto the area ahead and at the sidesoftheboat. In the drawings, the -"numeral I denotes;- the hull of a boat equipped with the improved dock ing lights," the numeral 2 shows theribs andi the batten strips. 'A bulkhead is shown at 4.

In equipping a boat with the improved lighting installation, the boat ow'n'er selects a location well toward the pro'w of the boat in a positionso that the raysbflight from the two installations will properly illuminate the-area ahead of the-boat as isshown-in 4; and ata point somewhatbelotv the rub rail 5 so that the light willstrikethe water-at the most favorable angle. Fi'gi l shows the average position on a medium siz cruiser,

The docking light aQWhole is I given the numeral-8.- In'the preferred form shown, it is-oval in shape with the long axisof the oval extending-=fere and-aft.-= Itis provided with'a-deepwell which is conical in form; the axis of thecone being set at an angle so'that the rays of light from each lamp will project across the pro'w'of the boat and also towards the side to the extent shown in Fig. 4, which represents an ideal are rangement. It will be seen that-the light from the two lamps will cover an area degrees-or somewhat less, in frontoi-the boat.

, The firststep in mounting the lights in the hull is to cut oval-shaped openingss in the hull ofxthe boat, care being taken tofmake'th'e hole as closely to theproper size as possible to receive the frahiefi Each [light comprises .an oval-shaped, 'rigid mainframe indicated by the numeral IO formed Withia, verticalwal1l I2 and a flanged rim; l4

preferably painted a dark color so as to minimize stray light reflections. At the base of the socket the frame is provided with the flange portion IS, the inner surface of which is formed with the curved seat l8 to receive the frusto spherical lamp housing indicated as a whole by the numeral 20.

Through the flanged rim [4 pass the securin bolts 22, the inner ends of which are threaded to receive the nuts 23. The stems of the bolts pass through an adapter in the form of a mounting block 25 located against the inside of the hull and through holes bored in the hull. The heads of the bolts bear against the oval-shaped clamping plate or ring 26 which fits closely around that portion of the wall l2 which projects outwardly of the hull.

.It will be noted that the hull of a boat at the region where the docking lights are .located is on a curve both fore-and-aft and also in a ver- In order to adapt the light to the surface to which it is attached, the mounting block 25 should be curved on its outer surface 25a to fit the curvature of the inside of the hull and the inner surface 25b should be flat to fit against the surface of the flange rim 14. In the form shown herein the mounting block 25 is a wood block which extends from the bulkhead 4 to the rib 2 and is provided with a central hole to receive the vertical Wall l2 of the body ID. The block 25 is channelled to accommodate the battens 3. After the surface 250. is properly formed, the surface 25b is planed to the proper angle to present a'flat surface against which the underside of the flanged rim I4 will fit, and this operation may be done after the block is secured in place.

Because of the compound curvature of the hull, the clamp plate or ring 26 is made of a material which will allow it to bend sufiiciently so that its inner surface will bear tightly against the side of the hull when the nuts 23 are drawn up. The clamp plate or ring is therefore preferably made of a ductile metal or it may be made of a plastic material if desired. It is important to have the ring 26 conform to the outer surface of the hull both for the appearance of the installation and also for watertightness.

After the hole 9 is cut in the hull, and the block 25 is in place, the wall I2 is passed through the opening and seated therein. The undersides and shanks of the bolts 22 and the underside of the ring 26 are thoroughly coated with a good grade of seam compound and then the ring and the bolts are put in place and the nuts 23 tightened to fasten the frame securely in position, drawing the ring 26 all around against the outer surface of the hull. The crack between the frame and the hull is now calked with the sealing com- Dound as shown at 28.

The lamp housing 20 is spherical on its outer surface so that it may be set at the desired angle in the socket l8. It is composed of an outer section 32 and an inner section 33 threaded together as shown in Fig. 3. Located in the holder is a sealed-beam lamp 35 which is held in position by a castellated clamp ring 36 threaded into the section 32, sealing gaskets 38 being located on either side of the lamp and held between a shoulder 39 on the section 32 and the lower edge of the ring 36. The wires 31to the lamp pass through a socket 40 on the section 33.

Before the lamp housing is placed in the frame the surface I8 is coated with a waterproof grease. The housing is then placed in position and a waterproof gasket or sealing device 42 is placed in the recess at the rear of the socket. This may either be a soft plastic ring, preferably made of neoprene which is liberally coated with the waterproof grease or it may be a special gasket shaped more or less closely to the cross-section of the :space which is to receive it. The clamp ring 44 is then placed over the inwardly projecting portion of the lamp housing and the screws 45 are passed through the ring and into sockets 46 on the outside of the flange portion l6. Before the screws 45 are fully tightened, the lamp housing is carefully adjusted and then the screws 45 are driven home to hold the housing in its final position, which, if the adjustment is correct, need not be changed. The tightening of the ring will force the gasket 42 to seal the crevice around 7 the outside of the lamp housing.

The final adjustment of the lamp housing on each side of the boat should be accurate. Each light should, for best results, be so set as to give light areas as shown in Fig. 4 with the beams from the two lamps blending directly ahead and covering wide areas on either side of the boat.

The light should strike the surface of the water at-a long angle.

It will be seen that with the equipment provided for herein, the boat owner is supplied with a new and highly efficient means of illuminating the areas of water ahead of and at the sides of the boat, which is set within the lines of the boat. The equipment not only serves to give the pilot muchbetter facilities for night navigation but the device adds to the appearance of the boat. While the equipment has been described with particular emphasis upon its use at the prow of the boat, it may also be employed at the sides or on the stern. While the frame is preferably oval or elliptical so as to give the desired range to the light rays, this is not essential.
