MARVIN MANUFAGTUR- me COMPANY, or URBANA, OHIO, A conronnrron or 01110 vEN'rILA'ron non wINnows Application filed August 30, 1927. Serial No. 216,473.
This invention relates to window screens,
it particularly relating to a screen in which the screening element is cloth stretched over and secured to a metal frame.
One of the objects of the invention is to provide improved means for securing the cloth to the metal frame; a more specific object is to provide means for so securing the screen cloth to the metal frame as to obviate 10 any tendency of the cloth to tear or loosen up at the pointsof attachment to thereby eliminate sagging of the cloth in the frame.
A further object of the invention is to provide a screen frame of this character which may be formed in sections slidably connected together and so constructed that additional sections may be added if needed without a1 tering the frame construction.
A further object of theinvention is to provide an arrangement whereby the screen proper may be readily removed for repairs or renewal. 7
Other objects of the invention will appear from the accompanying description and claims.
In the accompanying drawings:
Fig. 1 is an elevation of one side of a screen frame embodying my improvements, the frame being shown formed of a plurality of similarly formed sections, two complete sections being shown and a portion of a third section.
Fig. 2 is an end view.
Fig. 3 is an enlarged sectional view on the line aa of Fig. 1.
Fig. 5 is an elevation of the inner side of the cloth supporting sash, this member being alike in each section.
Fig. 6 is an end view of the same.
Fig. 7 is an enlarged view of a portion of the cloth sash showing one of the cloth securing prongs before bending to position to receive the cloth.
Fig. 8 is also a view of a portion of the cloth sash showing the prong bent to a position to receive the cloth.
Fig. 9 is a section on the line ee of Fig. 8.
Fig. 10 is an enlarged elevation of a porportion of the cloth sash and one of its prongs, together with a portion of the cloth,
showing the prongs bent to securing position; Referring to the drawings, each section of the frame is provided with a, rectangular cloth sash formed of sheet metal upon which the cloth is stretched and secured.- This sash as shown in Fig. 5 is formed with two longitudinal top and bottom strips 1 and 2" connected byvertical end strips3 and: l, these strips being connected together by spot -welding or in any other suitable manner. The inner edge of each strip is formed with a plurality of integral prongs 5, which when first cut occupy the position shown in Fig. 7 Each prong is then bent to the position shown'in Figs. 8 and 9 from which it will be seen that the base of the prong is bent in parallel spaced-apartrelation with the base of the sash, while the point of the prong is bent at right-angles to the base.- The cloth, indicated at 7, is then stretched upon the frame by inserting the prongs therethrough and each'prong then bent to the position shown in Fig. 11 in-which it will be seen that thecloth is firmlyclamped to the sash by the intermediate portion of the prongor that portion which formedthe bend between the base and point in the prong. By soforming the prongs, the intermediate portions of the prongs act as clampsto firmly clamp the cloth to the fiat surfaces of the sash and thereby prevent the openings in the cloth from enlarging due to the tension of the cloth and consequently obviates the cloth becoming loose on the sash and sagging.
The sashmembers, after the cloth has been stretched and secured thereon, are mounted in frames provided with interengaging parts edge of the end sash strips as indicated at 8, with the angularly projecting portion provided with small lugs or cars 9 bent against the faces of the end strips of the sash. The upper and lower portions of the frame consist of strips 11 each having its upper'edge bent at right angles as indicated at 10 so as to overlie the upper edge of the sash, with the outer edge of the portion 10 bent at rightthe prong and the sash.
3. A sash, a plurality of integral prongs formed on the inner edges of said sash to receive the cloth, each prong being so bent as to receive the cloth on the outer portion only thereof and clamp the cloth to the face of angles to form a laterally-offset tongue 12. 'the sash at a point removed from the metal The strips 8 and 10 are connected preferably by spot welding.
The frame of section B is constructed similar to that of section A with the exception that the upper and lower strips, indicated at 11, are each formed with a laterally-offset groove and to this end the upper edge of each strip 11 is bent at right angles as indicated at 13, thence inwardly at an incline as indicated at 14:, and thence outwardly in a direction parallel with the main portion 11 as indicated at 16, thus forming a groove 17 p In the present case section C is formed like section A with its tongue 12 engaged with the channel 17 of section B, although if desired section C could be formed with a channel portion 17 to slide on section A.
Each cloth supporting sash, after the cloth has been stretched and'secured thereon, is placed in its frame and secured thereto not only by the lugs 9 previously described, but also by tongues 18 which are punched inwardly from the overhanging portions of the frame members 11 and 11'. In assembling the sash with the frame, the sash is first slightly buckled so that its top and bottom strips 1 and 2 may be slipped under the tongues 18, after which the lugs '9 are bent against the sash frame to secure it in position; This arrangement enables the sash to be removed at any time for repairs or renewal.
By the manner described of securing th cloth to the sash, it will be seen that the material is firmly clamped to the flat face of the sash b an intermediate portion of each prong so that there is no opportunity for the holes in the cloth'made by the prongs enlarging thereby permitting the cloth to loosen in the sash and sag.
Having thus described my invention, I claim:
forming'the connection between the prong and the sash, and a sheet metal frame for said sash overlying said prongs.
4. A sash, a plurality of integral prongs formed on the inner edges of saidsash to receivethe cloth, each prong being so bent as to receive the cloth on the outer portion only thereof and to clamp the cloth to the face of the sash at a point removed from the metal forming the connection between the prong and the sash, a sheet metalframe for said sash overlying said prongs, and
means for removably connecting said sash with said frame. r
In testimony whereof, I have hereunto set my hand this 23rd day of August, 1927.
JOHN J. BITTER.
