COMBINATION PORT HOLE SCREEN AND WIND SCOOP Filed Nov. 6, 1959 April 25, 1961 9" so'ml l in a P w 3 INVENTOR. EARL. L. VhLAN COMBINATION PORT HOLE SCREEN AND WIND SCOOP Earl L. Milan, 5101 Broadway, Galveston, Tex. Filed Nov. 6, 1959, Ser. No. 851,406 4 Claims. (Cl. 114-177) Thisinvention relates to a novel combination port hole screen and wind scoop for use on ships and elsewhere.

The primary object of the invention is to provide a of the character indicated above, wherein the frame is a single extrusion, having a channel which removably receives the inner end of the scoop, and a channel which removably receives the edge of the screen, and screen edge being secured in place therein solely by means of a spline ring; and the frame being secured in place in a port hole solely by frictional engagement therein.

A further object of the invention is the provision, in a device of the character indicated above, of a one-piece frame which is an extrusion which can be made of aluminum, brass, copper or other metals, and of plastics which include fabrics, rubber, and other synthetic materials.

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific form of the invention is set forth in detail.

In the drawings:

Figure 1 is an outside or front end view of a device of the invention, shown installed in a ships port hole;

Figure 2 is an inside or rear end perspective view of the device, per se;

Figure 3 is an enlarged outside or'front end elevation of the device; and,

Figure 4 is a horizontal section, on the scale of Figure 3, taken on the line 44 of Figure 1.

Referring in detail to the drawings, wherein like numerals designate like parts throughout the several views, the numeral generally designates a combination device of the invention, shown installed in a port hole 12 in a ships skin 14. The port hole 12 can be of any 1 suitable annular form which provides a smooth inner sidewall 16, with which the device 10 is frictionally engaged from the rear or inside, and need not be otherwise secured.

The device 10 comprises an annular frame 18 which is designedly a one-piece extrusion of metal or synthetics, which produces a relatively thin peripheral wall 20 which is composed of a plain inner or rear cylindrical portion 22 and an outer or front frustro-conical portion 24, with a lateral annular stop flange 26 on the rear edge of the inner portion 22. Integral with and formed on the radially inward side of the outer portion 24 is an annular extension 28.

The extension 28 comprises an L-shaped flange 30 having a foot portion 32 reaching inwardly away from the ice outer peripheral wall portion 24, and a standard portion 34 which extends forwardly from the foot portion 32 and is parallel spaced from the wall portion 24, so as to define a scoop-receiving channel 36.

The extension 28 further comprises another and smaller L-shaped flange 38 which has a foot portion 40 formed on and reaching inwardly from an intermediate part of the standard portion 34 of the flange '30, and a relatively short standard portion 42 which extends rearwardly from the foot portion 40, so as to define ascreen edge receiving channel 44. A retaining bead 46 is formed on the free edge of the standard portion 42 andextends part way across the channel 44. Hinged installing and removing handles 48 are provided on the inner surface of the rear frame wall portion 32. i

A disc screen 50, of suitable flexible material, islarger in diameter than the flange 38 and is positioned across the frame 18 and engaged with the rear side of the flange 38 and has a free peripheral edge portion 52 which is deformed and engaged into the channel 44, in which it is removably secured by means of a stiif resilient spline ring 54. The ring 54 is of sufficient cross-section and appropriate diameter that the screen edge portion 52 is clamped in the channel 44, with the ring retainably engaged behind or beneath the retaining bead 46. With this arrangement, removal of a damaged screen is merely a matter of prying the ring 54 out of the channel 44, with a suitable implement, and pulling the screen 50 free, installation ofa replacement screen being merely a matter of springing the ring54 into the channel 44 over the edge portion of the new screen.

An air scoop 56 comprises a preferably two-thirds circular forwardly tapered tubular form having arcuate ends 58, and a free inner or rear edge portion 60, which fits into the channel 36, and can be rotated therein to a desired position, until fixed removably in place, as by means of screws 62, which are threaded radially inwardly through forward frame wall portion 24, the scoop wall 64, and the standard portion 42 of the flange 3 8, as shown in Figure 4.

The screws 62 can be the same screws which held a replaced scoop in the channel 36, and be engaged through holes 64 and 66 already present in the standard portion 42 and the frame portion 24. Thus, replacement of a damaged scoop 56 is merely a matter of backing onto the screws 62, pulling the scoop out of the channel 36, re placing it with a new scoop, and threading the screws 62 in place through the new scoop.

It is to be noted that, heretofore, frames, corresponding to the extruded frame 18, have been expensively and disadvantageously made of sheet metal cut to shape and the resultant annular form then formed to provide flanges on the edges of the form to stiffen the same and to provide securement for the peripheral edge of the screen, the screen edge being then soldered to a flange, with the result that the frames so made by succeeding time-consuming and troublesome operations lacked desirable rigidity and finish and provided no desirable replaceability of the screens. All of these disadvantages are overcome by the present in cost of production.

While there has been shown and described herein a preferred form of the invention, it is to be understood that the invention is not necessarily confined thereto, and that any change or changes in the structure of and in the relative arrangements of components thereof are contemplated as being within the scope of the invention as Patented Apr. 25, 1961 I invention without a necessary increase surface beingdiametered for africtional fit in a port hole,
