lMPROVEMENT IN DECK-LIGHTS.
Specification forming part of Letters Patent No. 136,299, dattd FCbIllfilY 25, 1573.
To all whom it may concern:
Be it known that I, ISAAC M. BEARSE, of Boston, Suflolk county, State of Massachusetts, have invented an Improved Deck Light; and I do hereby declare the following description and accompanyingdrawing are sufficient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvement without further invention or experiment.
My invention relates to an improved arrangement for securing what is known as the 'bulls-eye deck-light in the decks of ships and other places where such lights are used, by which several advantages over the ordinary method are secured.
In order to explain my invention so that others will be able to understand its construction and object, reference is had to the accompanying drawing forming a part of this specification, in which- Figurelis a vertical section of my invention. Fig. 2 is a plan view.
Let A represent a section of the deck or other floor in which it is desired to place a glass sky-light of the class above mentioned. The glass deck-light, which is usually employed for this purpose, and which is known as a bulls-eye light, consists of a solid piece of glass, the downward-projecting portion of which is rounded in the form of a hemisphere. This bulls-eye is usually screwed into the deck from below, so that its rounded or hemispherical portion will project down into a bell-shaped 0r flaring concavity on the under side of the deck, the upper flat side coming up level with the surface of the deck or floor. As the deck wears down this upper flat side of the glass bulls-eye is left projecting above the surface of the deck, and the corners or edges become nicked and broken from one cause or another, rendering its appearance unsightly, and frequently causing them to leak. By my arrangement I construct the bulls-eye B with a horizontal flange, O, which projects entirely around it a short distance below its upper flat surface, as shown. The lower side of the deck I then provide with a flaring concavity in the same manner as is ordinarily done, in order to allow the rays of light to diverge in all directions from the bulls-eye, after which I countersink the upper side of the deck at m, so that it will admit the flange O, leaving a shoulder or seat, 6, for the flange or a washer, as the case may be, to rest upon. This countersink communicates with the concavity below. In some cases I shall first place a washer, f, on the seat 0, which will prevent theflange c from sinking into thewood. The glass bulls-eye is then placed in the hole, so that the flange will rest upon the washer, and above the flange I will place a metal ring, 9, which is provided with ears 1?, which rest in corresponding recesses in the deck. The upper face of the ring will then be flush with the deck, and also with the upper flat face of the deck-light, so that the whole will present a level and even surface. Screws can be inserted through the ears iinto the deck be neath, and the proper luting applied around the edges to render it water-proof. By this arrangement the edge of the bulls-eye is pro tected by the metal binding, and when the deck wears down the upper recess can be slightly deepened, and the surfaces again made to correspond.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
The bulls-eye B with its flange G, in combination with the countersink m, seat 0, and upper fastening-ring g, either with or without the washer f, all combined and arranged substantially as and for the purpose above described.
In witness whereof I hereunto set my hand and seal.
