Fig. 9 illustrates this form of the clamping member in engagement with the frame of Fig. 8 to form a holder, and;

Fig. 10 is an end view of the frame member shown in Fig. 9.

The embodiment of the invention shown in Figs. 3 and 4 comprises a frame 3 with a clamping member 4 arranged to engage therewith. The frame 3 comprises thelegs 6 and I, of which the former terminates in the recurve or-bead 8 adja-' cent the upper edge thereof. An arcuate channel 9 is arranged at the point of juncture of the legs 6 and 'l in the frame 3. Adjacent the arcuate channel 9, and substantially parallel therewith is the second arcuate channel ill, or displaced portionarranged in the surface of the leg 1. The clamping member 4 is also formed by legs 6' and 1' having a channeled portion 9' at the point of juncture such elements being com plemental to elements having the same unprimed numbers in the frame 3. A rib-l3j arranged in the leg 6 provides resiliency in the clamping member, whereby after the channels 9 and 9' have been fitted together, the end M can be removably locked against the nether portion l5 ofthe recurve 8 by bending the clamping member along the bead I3, and snapping it into position adjacent the portion I5. A plurality of prongs 15 are arranged in the leg 1, which prongs are adjacent the arcuate channel or displaced portion ID of the leg I ofthe frame 3.

In order to engage screen or other foraminous sheet in the holder, the prongs [5 are passed through the fabric and the clamping member 4 is then positioned in interlocking relation with'the frame 3, which had been previously positioned on the opposite side of the sheet. The'prongs 15 pass into the arcuate channel, or displaced por tion It], and the complementary channels 9 and 9' are fitted together. The leg 6' of the clamping member 4 is then bent along the bead [3, so that its upper end I4 engages the recurve 8 along its portion l5, whereby the clamping member 4 and frame 3 are removably retained in looking relation, as better illustrated in Fig. 4. r In Fig. 1, a section of the holder, is illustrated as comprising two elements l6 and H, which are joined togetheralong their point of contact at l8.

as previously described. The holder may be of any suitable shape or configuration, and as practical matter it has been found that the usual form will be rectangular, which is the shape of the ordinary Window used for construction purposes today.

Figs. 8, 9 and 10 illustrate an alternate embodiment of the invention, wherein the clamping member 4 is shown as having its upper end 20 redoubled. Prongs l5 are arranged on the leg I, there being an arcuate channel 9 adjacent the point of juncture of the leg 7' With the leg 6. The frame 3' is best seen in Fig. 10 as comprising the legs 5 and l with the arcuate channel 9 adjacent their point of juncture. A displaced portion or arcuate channel I0 is arranged in the leg I adjacent the arcuate channel 9 to receive the prongs [5 when the frame and clamping mem- 4 and it is to be noted that little or substantially no damage will be incurred by the screen fabric, which has been mounted in the holder over a period of time.

A holder, in accordance with the present invention, can be formed of any suitable material. such as plastic, metal or the like, and will be substantially permanent throughout the lifetime of the screen fabric, which it holds.

Broadly, the invention contemplates a holder for a sheet of foraminous material such as screen fabric and the like, and in particular, to an imber are in interlocking relation, as best seen in Fig. 9.

A portion of the screen fabric 22 is engaged by the prongs l5, which fit in the displaced portion Hi. It is to be noted that the complementary arcuate channels 9 and 9 extend for more than half a circle, so that the lip 23 is formed at the point of juncture of the arcuate channel 9 and the leg I.

A similarly shaped lip 24 is formed at the point of juncture of the arcuate channel 9' with the leg I. In order to retain the screen fabric in position on the holder in this embodiment after the prongs 3 have been passed through such screen, the upper end 26 of the leg 6 is engaged in the recurve portion of the clamping member 3, and the complementary channels 9 and 9' are then snapped in interlocking relation, which channels remain in interlocking relation due to the configuration of the lips 23 and 24.

A third form of the invention is illustrated in Figs. 5, 6 and 7, wherein the clamping member 4" comprises the legs 6 and 1', having an arcuate channel 9, along their point of juncture. Prongs l5 are arranged in the leg I of such clamping member. Fig. '7 shows the configuration of the frame member 3", which has intersecting legs 6 and l, with the arcuate channel 9 formed along their point of juncture. The upper edge of the leg 6 is inwardly flanged to form a shoulder or abutment 28. The leg I is provided with an arcuate channel or displaced portion ID, to fit adjacent the prongs I5 when the frame and clamping member are in interlocking relationship, as best seen in Fig. 6. The upper end 29 of the clamping member fits immediately below the abutment or shoulder 28, after the prongs 15 have been engaged with screen fabric or the like, and the channels 9 and 9 assembled in interlocking relation. In order to remain the frame 3 and clamping member 4" in such relationship on opposite sides of the screen, a retainer strip 30 is provided to fit over the upper end of the frame and clamping adjacent the abutment or shoulder 28.

Fig. 2 illustrates a holder formed in accordance with the embodiment illustrated in Figs. 5, 6 and'l, wherein the screen fabric 3| is shown en gaged by the clamping member 4' .Several distinct advantages reside in the construction disclosed and claimed herein. The manufacture of the component parts is simple, and the cost thereof is relatively low. Additionally, the frame and clamping member can readily bepositioned on opposite sides of the screen in order to form a holder therefor. The manufacture of the holder is readily facilitated,

proved construction of holder for window screen.
