UNITED` STATES MENDEL SCHWARTZ, 0F BROOKLYN, NEW YORK.

PORT-LIGHT.

Application led December 2, 1919, Serial No. 341,856.

T 0 @ZZ whom t may concern Be it known lthat I, MENDEL SCHWARTZ, a citizen of the United States, residing formerly in the city and county of Philadelphia, State of Pennsylvania,now residing at Brooklyn, in. the county of Kings, State of New York, have invented a new and useful Port-Light, of which the -following is a specification.

My invention consists of a port light which is constructed of interfitting ring-like outer and inner members which are connectible by a movable oint which also permits the disconnection of said members, a ring-like iframe carrying reticulated material which is received in the outer ring-like member and is adapted to admit ventilation through the device and prevent the entrance of insects therethrough, means on the ringlike members for retaining sai-d frame firmly in position, and additional means on the outer member adapted to tighten the peripheral portion of said frame Vin the re-V ceiving ring.

rlfhe invention is satisfactorily illustrated in the accompanying` drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific details shown and described, as long as they are within the spirit or scope of the claims.

Figure 1 represents a front elevation of a port light embodying my invention.

Fig. 2 represents a rear view thereof.

Fig. 3 represents a rear view of the eX- terior member of the device.

Fig. 4 represents a diametrical section of the reticulated member of the device.

Fig. 5 represents a diametrical section on line 5-5 Fig. 2.

Fig. 6 represents a diametrical section on line 6-6 Fig. 2, including certain portions of the place of application of the device.

Fig. 7 represents a diametrical section of portions of the members of the device in separated condition. Y Figs. 8 and 9 represent other embodiments of the invention.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings. f

1 designates the exterior member of the device, the same consisting of a ring having on its front portion the outturned bead 2, and the inturned rim or flange 3.

4 designates a ring-like frame to which the peripheral portion of the piece 5 of Specification of LettersPatent.

gauze or other reticulated` materialV is secured, said frame being seated against the flange 3 and so prevented from being displaced outwardly.

In order to hold said frame 4 in position on the flange 3 there are secured to the inner e face of the ring member 1 the inturned lugs 6 whose outer ends are adapted to contact with the outer periphery of the frame 4 at intervals and grip tightly against the same whereby said frame 4 is prevented from rotation.

7 designates the inner member of the device, the same consisting of a ring having on its front portion the outturned flange 8, and on its rearv portion the inturned flange 9, the diameter of said member 7 being slightly less than the diameter of the member 1, it being noticed said member 7 is adapted to enter the member 1 concentric therewith. Then the flange 8 bears against the frame 4 of the reticulated material and holds the sameV against inward motion and displacement while the flange 9 contacts with and overlaps the inner edge of the member' 1 and forms av close joint therewith and correctly positions thev member 7 for subsequent locking of the two members as will now be described.

On the inner face of the member 1 are the inturned studs 10 at intervals. In the member 7 are the Lshaped slots 11 at intervals adapted to receive said studs forming bayonet-joints Yfor connecting the two members, it being evident that when the studs enter the receiving portions of said slots, the member 7 is turned when said studs ride into the other portions of said slots and so the members are locked as most plainly shown in Fig. 5, a feature not new per se.

When, however, the member 7 is turned in reverse direction, the studs are in communi cation with the receivingk portions of the slots 11, then said member 7 may be drawn out of the member 1 and entirely removed therefrom when so required.

On the inner side of the member 7 are the thumb or finger piecesv 12 for convenience or" turning or rotating the member 7.

In Fig. 6 is shown the collar 13 on the side of a ship or other place of service of the port light, the same being connected with said side or place by the bolts 14, and nuts thereon or other suitable means, it being noticed that the device is adapted to be ttted in said collar from without, when rections on the collar 13, and soV remainingv reliably in its applied position.

In order to hold the device tightly in the collar 13 there are secured to the exterior of the side of the outer ring 1 the resilient tongues 15, see Figs. 5, 7, 8 and 9, which project outwardly from said side and are adapted to enter said collar 13 and engage the inner face thereof, and press against theV same, as most plainly shown in Fig. 9, while also being resilient 1n their nature,

and providing cushions which take up any strain or shocks on the port light.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, isc- Y 1. In a port light, inner and outer ring members, a reticulated material in the outer member, and means adapted to connect said members, the outer ring member having an inturned rim on which the peripheral frame of said reticulated material is adapted to be seated, the inner ring member having in front an interned rim which is adapted to bear against said frame, and at the rear an outturned flange which is adapted to overlappingly engage the inner edge of the outer 4ring member.

2. In a port light, inner and outer ring members, a reticulated material in the outer member, and means adapted to connect said member, the outer ring member having an inturned rim on Which the peripheral frame of said reticulated material is adapted to be seated, the inner ring member having in front an inturned rim which is adapted to bear against said frame,rand at the rear an outturned flange which is adapted to overlappinglyengage theinner edge ofthe outer ring member, said outer ring member having also in front an outturned bead which j is continuous with the inturned rim on said member.

3. In a port light, inner and outer ringV terial, means on the inner ring adapted to4 engage said frame and resilient cushions on the outer side of the outer ring.
