TREWR EN 5 3 I HINGED LIGHT Filed Ma 16, 1944 v Extented Aug. 19, 1947 UNITED STATES PATENT OFFICE HINGED LIGHT John Charles Frederick Trewren, Sidcup, England, assignor to J. Stone & Company, Deptford, England, a British company Application May 16, 1944, Serial No. 535,865 In Great Britain May 21, 1943 3 Claims. (01. 114-178) 1 2 This invention of improvements in hinged lugs (1 with a handle 1 (Figure 1). For m ll lights such as are used for ships port-holes, has light, only two wedge lugs h may be required and for its object to provide a simple but effective these would be disposed so as to be spaced by a tightening means for securing the glass door considerable angle from the hinge lugs a as tightly against its seating in the closed position 5 shown in Figure 1. At a point on its periphery and, in combination therewith, means for enaadjacent to one of the hinge lugs, the wedging bling the glass door to be held in different ang l ring R is formed fitted With a P j io h positions when opened so that the amount of which may have a form somewhat like that of ventilation through the door opening is readily a pinion tooth. The circular fixed frame or is t ll d, formed at appropriate points with claw-like lugs According to this invention, a revoluble wedg m having wedging surfaces for co-operating with ing ring, revolubly mounted on the hingedly those of the wedge lugs h of the wedging ring h. mounted glass door, is provided with a locking Also, it is formed with two fixed hinge lugs m m device such as a pin projection or tooth, which, ith which the hinge h of t d are by turning the ring, when the glass door is in an 5 hingedly engaged. One of these fixed lugs, open position, can be brought into engagement namely the lower one marked m is formed with a selected one of several indentations or around its periphery with a number of teeth or teeth ona fixed hinge lug, such engagement being indentations so that this lug has somewhat the effective for retaining the glass door in a corappearance of a segment of a fixed pinion as responding angular position. Various degrees of seen clearly in Figures 3 and 4. When the door opening between minimum opening and full openis closed, as in Figures 1 to 3, the wedging ring it ing can be provided for. is turned clockwise by means of its handle Z In order to enable the invention to be readily through a small arc. This turning movement understood, reference is made to the accompany-- may be limited by a stop pin it (Figure 1) on the ing drawing, whereindoor ring engaging in an arcual slot 0" in the Fi e 1 s an Elevation. as n from the inwedging ring, and is effective for causing the terior of a ship, of a closed port-hole light emwedge lugs h to engage the Wedge surfaces of bodying the present improvements. the claws m and efiect a tight seating of the door Figure 2 is a plan section taken on the line a. When the door is to be opened, the wedging IL-II of Figure l. ring h is turned reversely and this removes the Figure 3 is a plan section taken on the line wedge lugs h from behind the claws m so that IIIIII of Figure 1, and the lugs h clear the claws m as the door is turned Figure 4 is a section similar to Figure 3 but upon its hinges. When the door has been opened Showin t e hinged o r light a tened in an to a desired extent, the wedging ring is turned open position. in the same direction as that for producing the Referring t the drawing the inged door 01' wedging action but this movement now causes light Comprises a Circular un metal ring (1 having the tooth-like projection k to enter between two lugs a and formed with an annular and interof the teeth formed on the fixed hinge lug in so nally screw threaded flange b within which is that the door a is now locked in the desired open inserted the glass 0 and a screw threaded glazing 40 position. This will be understood from Figure 4 ring d for securing the glass. In one face, the which shows the door a swung to a position at door ring is formed with a circular groove in right angles to the fixed frame g and locked in which is fixed a packing ring e for making waterthat position by engagement of the projection 71 tight engagement with a seating lip 3 on the fixed in the notch between the second and third teeth frame g. In its periphery, the door ring is of the fixed hinge lug m If the hinges are dis formed with a rectangular groove one side of posed at the side of the door, the position of the which is open towards the other face of the ring. handle Z, when the door is locked in an open In this groove there is revolubly inserted a wedgposition, is a little lower than the position seen ing ring it, which is retained in the groove by a in Figure 1 and is such that its weight tends to housing ring 9' secured by screws it (Figure 2) to keep the ring it in locking engagement and to rethe said other face of the door ring. Around its sist vibrational effects which otherwise might periphery, the wedging ring it is formed with possibly cause the ring to turn in the direction two or more lugs b with inclined faces to serve for unlocking the projection h from the teeth of as wedges. It is also formed or fitted at another the lug m point on its periphery, and distant from the hinge The advantages of the device are its simplicity,
the quickness and ease with which the door can be closed and tightened on its seating, the absence of gears or screw fastenings, and the utilization of a single part, namely the wedging ring it, for the dual purpose of tightly sealing the door in a closed position and for locking it in a selected open position.
If desired, a dead light can be fitted and can either be hinged separately or on the same hinge pin as the door a. This dead light may also be fitted with a wedging ring of the kind described.
I claim:
1. A hinged port light comprising, a fixed circular frame, a swingable circular frame, hinge means connecting the two frames so as to permit swinging of the swingable frame relative to the fixed frame, a wedging ring revolubly mounted on said swingable frame for circular adjustment around the latter, wedge lugs on said wedg'i'ng ring, claw lugs on said fixed frame for cooperating with said wedge lugs when said wedging ring is circularly adjusted in one direction, a series of stop formations spaced around the hinge axis in a pla e perpendicular to such axis, and means on said wedging ring to be brought into interlocking engagement with a selected one of said stop formations by a circular adjustment of said wedgin ring after said swingable frame has been swung to an open position in which it is angularly disposed in relation to the fixed frame. 7
2. A hinged port light comprising a fixed circular frame, a swingable circular frame, hinge means comprising hinge lugs and a hinge pin connecting the two frames so as to permit swinging of the swingable frame about the axis of the hinge pin, a wedging ring revolubly mounted on said swingable frame for circular adjustment around the latter, wedge lugs on said wedging ring, claw lugs on said fixed frame for cooperating with said wedge lugs when said wedging ring is circularly adjusted in one direction, a series of indentations in alternation with projections formed on one of the hinge lugs, and a projection on the wedging ring adapted for being brought into interlocking engagement with a selected one of said indentations by a circular adjustment of said wedging ring in an appropriate direction after said swingable frame has been swung to an open position in which it is angularly disposed in relation to the fixed frame.
3. A hinged port light as claimed in claim 2, and. further comprising an operating handle on the wed'ging ring, the said handle being so disposed that its weight tends to turn the wedging ring in the direction for preserving interlocking engagement between the projection on the wedging ring and a selected one of the said indentations.
