` PORT LIGHT.

Application filed January 6, 1922, Serial No. 527,376. Renewed June 5, 1925.

To all whom it may. concern.'

Be itknown that'I, HARRY B. HILLS, a citizen of the United States, vresiding at Hudson, in the Ycounty of Columbia and claims. v A

In the acompanyingdrawings, Fig. l is a front elevation of a port light embodying my invention. Fig. 2 is a 'cross-sectional view, the section being taken on the line 2-2 of Fig. l. Fig. 3 is a detail view of the hinge connection between the light and supporting frame. Fig. 4 is a detail view y y of a means for lifting the cover from its seat.

Similar letters of reference designate corresponding parts in all of the figures. y

A designates an annular rin which isl y suitably secured by bolts 'or rivets in an opening, which for the purposes of illustrating my invention, is formed vin a ships plating. vided with a flange @which extends into the opening, andy lafsecond flange al which is provided with a screw thread. The flange al is also provided with'a lip a which will be referred to later. It is also `provided with' a seat, here shown as being in the form of a gasket G against which acover E Yis levenly and firmly seated as hereinafter described.` 0 BV designates a-secoifd rino* which is interiorly' screw-threaded and ori-the flange 41,- andl is provided with la' flange b. 'The e ring Bis here shownY asv being provided'with State of New York, have invented certain point out the novel features thereof in As here shown, the ring is pro-V which the shaft C extends. The cover E is also provided with an ear e5, carrying a pin c6 which extends into an opening Z provided in the worm D, the opening d being of such length that the pin e6 can be moved inwards and outwards a short distance. It will be observed that when the worm D is rotated on the shaft C, it will cause the cover E to rotate with itvthrough the pin e6, the shaft C acting as the center on which theicover E rotates.

Rotation of the worm D is caused by the engagement therewith of spiral teeth f formed on or carried by a ring F which is revolved in the casing formed by the two rings A and B. The ring F is revolved by means of the gear teeth f1 formed on or carried by the ring F which are engaged by a spur gear f2, mounted on a shaft f3, which also carries an operating handle f4. The ring F is also provided with a series of wedging surfaces f5 which co-act with a like number of wedging surfaces c7 carried by the cover E, and which are beneath the wedging surfaces f5. The ring F is here shown as bein confined in the ring B by means of the flange b and the lip a2 which fits in a shouldered recess f formed in the ring F. By this arrangement the ring is not only confined to its seat, but distortion of its shape is prevented, thereby insuring correct gearing engagements with the gear f2 and worm D.

l Referring to Fig. 1 which shows the cover in its closed position, by turning the handle f4, the ring F is revolved in its casing, and the first part of its movement causes the wedging vsurfaces f5 and e? to be disengaged. The continued movement of the ring causes the teeth f to engage the worm D to rotate it onthe shaft C, and when it rotates it carries the cover yE'with it to thereby uncoverl the -f opening. A reverse rotation 'of the handle f4 causes the rotation of the cover E `inthe reverse direction to close the opening, and after the cover has reached its closed position on the gasket G, the teeth f are disengaged from the worm D. The further rotation ofthe ring F causes its wedging surfaces to engage the wedging surfaces e7,l which co-act to press the frame e evenly and firmly against the'gasket G, irrespective of the wear of the gasket to make a water-tight joint.V This vinward movement of the cover E is permitted because of the elongated openings in its ears e2, cf and the lengthened opening (l into which the pin e6 extends.

In the event that the cover E for the opening should remain closed for a considerable period, it may be that the edge of the cover engaging the gasket G will stick tast to the gl slet, and require some force to break itloose. To overcome this, I provide a lug o1' projection /t on the frame c (see Figs. l and a) which is engaged by a bevel edge k1, which as here shown, is formed on one of the wedges or it may be a separate projection. During the operation ot the pinion f2 'to open the cover, when the wedging surfaces f5 and el are about to be or are disengaged, the edge 71,1 engages the lug or projection to torce or lift the frame c out of engagement with the gasket Gr. The continued operation of the pinion f2 raises the cover as above described.

Having thus described my invention, what I claim as new is:

l. The combination with a casing for an opening; a cover for covering and uncovering the opening; a pivotal connection between the casing and cover; a ring having gear teeth for moving the cover on the pivotal connection; a shouldered recess on said ring; and a lip fitting in said recess to prevent its distortion when moving the cover on its pivotal connection.

2. The combination with a casing for an opening; a cover for covering and uncovering the opening; a pivotal connection between the cover and casing; means for moving the cover on its pivotal connection comprising a ring having gear teeth; a shouldered recess on said ring; and a lip carried by the casing for fitting in said recess.

3. The combination with a casing for an opening, said casing carrying a lip; a cover for covering and uncovering the opening; a pivotal connection between the cover and casing; means for moving the cover on its pivotal connection comprising a ring having gear teeth; a shouldered recess on said ring; and a second ring for holding the gear ring in engagement with the lip.

4. In combination, a casing provided with an opening and with a seat, a cover for said opening, a member mounted `to oscillate, means controlled by oscillation of said member for moving said cover into and out of closing position against its seat, and means also controlled by movement of said member in the opening direction for separating the cover from the seat.

5. In combination, a casing provided with an opening and with a seat, a cover for said opening, a member mounted to oscillate, means controlled by oscillation ot' said member for moving said cover int-o and out of closing position against its seat, a lug iXed -to the cover, and a shoulder fixed to said member and coacting with said lug to separate the cover from its seat during movement of the member in opening direction.

6.A In combination, a casing provided with an opening and with a seat, a cover for said opening, a member mounted to oscillate, means controlled by movement ot' said member in one direction for closing and locking the cover and in the other direction tor unlocking and opening the cover, and means also controlled by movement of said member in the opening direction tor separating the cover from its seat.
