ANCHORS FOR METAL WINDOWS Filed Oct. 31. 1962 2 SheecQs-Sheet 2 INVENTORS United States Patent O ,184,016 ANCHORS FOR METAL WINDOWS Arthur Smith, Amityville, and Peter Lacoppola and John S. Daugherty, Plainview, N.Y., assignors to General Bronze Corporation, Garden City, L.I., N.Y.

Filed Oct. 31, 1962, Ser. No. 234,440 6 Claims. (Cl. 189-75) This invention relates to a metal window and easing combination, particularly constructed of metal.

An object of the invention resides in the provision of a window frame assembly which includes a sash frame and positioning and retaining anchor members which may be twisted on to the jambs, sill and header and which may be attached in window openings defined by various wall constructions and in walls of dilferent thicknesses.

A further object of the invention resides in so constructing the anchor members that they will serve to rigidify the sash frame to the metal casings of various depths when such are employed, and to maintain the casings in a given relation to the sash frame and in the Window opening, without the additional anchorage usually employed.

Other objects of the invention will appear as the description of the illustrated embodiment of the invention progresses.

In the drawing which illustrates this embodiment,

FIGURE 1 is a vertical sectional View disclosing a position of the sill and header anchors in relation to the window sash frame and easing;

FIGURE 2 is a horizontal sectional view showing the relative position of a jamb anchor; and

FIGURES 3, 4 and 5 are perspective views of the header, sill and jamb anchors.

Referring to the drawings, the sash frame is indicated generally by the reference character A, the casing by the reference character B and the anchor members on the sill, header and jambs by the characters C, D and E, respectively.

In the metal frame window industry, the sash frame A and the casing B are attached together in a number of different ways, but in the drawings, we have shown a recess or horizontal channel 2 in the sill 3 of frame A formed by rearwardly extending spaced parallel flanges 4 and 6 at the inner edge of said sill. The recess or channel 2 receives and secures between said flanges the depending flange 8 at the front edge of the horizontal lower plate or wall portion 10 of the casing B which flange is forced or snapped into the channel 2.

The header 16 of the sash frame and the upper horizontal wall portion 10 of the casing are secured together in a similar manner to that employed in securing lower wall 10 to the sill.

The jambs are each provided with similar but vertical channels 12 defined in part by rearwardly extending inclined flanges 61, FIG. 2 and each receives a similar flange 14' on the vertical wall portions 14 of the casing, FIG. 2.

According to our invention one or more anchors are used in connection with each of the sills, headers and jambs to secure and position the sash frame and casing in respect to the window opening. In the drawings, we have shown, for the purpose of illustrating our invention, one anchor for each of said frame elements.

The anchor C for the sill is attached to the sill and to the framing of the window opening regardless of the character of the material of that framing.

To effectuate this attachment the sill 3 is, adjacent its outer edge and at its under side, provided with a longitudinally extending channel-20 which, so. far as the anchoring at the sill is concerned may extend the full length of the sill or partially thereof. This channel is formed in part by an inwardly directed flange 22 in cooperation with the sill. The opposite or inner edge of said sill 3 is provided with a similar channel 24 which is formed in part by a flange 26 in cooperatioin with the sill. Additionally, when a casing is used, its lower wall portion 10 is formed with an angle flange 60 to provide a channel 28 at the rear edge thereof, said flanges 8 and 60 in eflect defining with wall 10 an open side channel of which ,rear channel 28 is a part.

These channels in sill 3 and wall 10 are for the purpose of receiving various parts of the sill anchor C which comprises, FIG. 4, a toe portion 30, a heel portion 32, an intermediate portion 34 and a shank portion 36, a supporting base 38 and an attaching plate 40 for attachment of the anchor to the building structure.

The heel portion 32 is provided with a resilient laterally extending projection 33 which extends therefrom at an angle somewhat greater than a right angle so that when the anchor is twisted and snapped into place in the position indicated in FIG. 1 and with projection 33 bearing yieldingly against the inner surface of the base of channel 28, the projection 33 will assist in maintaining the anchor in effective operative position wherein the end of the toe portion 30 is seated in channel 20, the intermediate portion 34 in channel 24 and the heel portion 32 in channel 28.

The shank portion 36 supports the inner edge of sill 3 and the lower plate 10 of the casing so that no additional reinforcing of said sill and said casing is required to prevent deflection or deformation of the assembly of said parts when the sill or the casing is subjected to weight.

When manually positioning the anchor C in engagement with the sill as described, the anchor is initially canted off at an angle to its final position and, as shown in FIG. 1, the toe portion 30 is placed in the channel 20. As the anchor is swung from said initial angular position to normal substantially perpendicular position, the intermediate portion 34 will snap into the channel 24 due to the slight resiliency of the metal of the anchor and, as the swinging movement is continued, the heel portion 32 and laterally projecting flange 33 will snap into the channel 28 in the casing due to the resiliency and position of the projection 33.

The flanges defining these channels, as 20, 24 and 28, and the resiliency of the metal of the anchor will hold the anchor in position so that when it is attached to the building structure as by a bolt, or the like, not shown, passing through a hole 5 in attaching plate 40, the sill and the casing will be anchored and positioned at once.

Although the header anchor D is of somewhat different form than the sill anchor it has portions which act in substantially the same manner to anchor and position the frame and easing at the header.

Thus, the header 16 of the frame has an outer channel 20 formed by a flange 22' in cooperation with the header, and an inner channel 24' formed in part by a flange 26 in cooperation with the header and an outer channel 9 formed in part by a bent down flange 11. The top wall portion 10' of the casing B has a channel 28 defined in part by angle flange 60 at its rear edge and an upturned flange 8' at its front edge which is operatively retained in channel 9 by flange 11 of the frame.

The header anchor D is provided with a toe portion 30', FIG. 3, an intermediate portion 34' and a rear portion 32' which portions snap into the channels 24' and 28', respectively.

The heel portion of anchor D includes a resilient projection 33' which extends therefrom at an angle somewhat greater than a right angle so that when the anchor D is snapped into place, FIG. 1, the resiliency of the projection will assist in maintaining it in its proper position.

The toe portion of the header anchor D is also provided with a positioning slot 42 which engages the adjacent flange 22' of the frame; and the anchor D advantageously includes a fastening plate 38' having holes 48 adapted to receive bolts or the like for attachment to the building structure.

In assembling, the header anchor D is canted and moved manually into position in a manner similar to that employed in connection with the application of the sill anchor C, the slight resiliency of the metal cooperating to facilitate operation when the fit is tight.

The jamb anchor E is functionally similar to the sill and header anchors, differing, however, in some structural details. Thus, FIG. 5, it has the toe portion 50, the heel portion 52, the intermediate portion 54 and the shank portion 56 all conveniently embodied in the form of a flat plate. Toe portion 50 thereof has a slot 51 and intermediate portion 54 has a slot 55. To operatively position anchor E the toe and intermediate portions 5% and 54, respectively, are initially canted and, as seen in FIG. 2, snap into channels in the jambs of the sash frame, similar to those in the header and sill, while the heel portion52 snaps into the channel 28" defined in part by rear angle flange oil" in the casing. Also slot 51 engages flange 57 and slot 55 engages flange 59.

The shank portion 56 of this jamb anchor E has bolt holes 58 adapted to receive bolts by which the plate may be attached to the building structure either in a previously formed window opening or as the masonry is built up.

in the case of anchor C, the distance preferably between the open sides of the toe channel 263* and of the intermediate channel 24 is less than the distance between the extremities of the toe portion 30 and the intermediate portion 34 of said anchor C; and the intervening portion of the anchor is somewhat resilient so that, when the toe and intermediate portions of the anchor are snapped into the channels 26 and 24 from a canted position, the anchor will be maintained in its predetermined relation to the frame.

For a like purpose the distance between the open side of the toe channel 20 and that of the heel channel 28 in the casing is less than the distance between the extremities of the toe and'heel portions of the anchor so that the heel portion resiliently will be held in position.

For more effective interlocking of the parts and as seen in FIGS. 1 and 4, an edge of anchor C is notched at 35 to engage flange 26, FIG. 1; an edge of anchor D is notched at 37 to engage flange 26; and anchor E is notched at 51 to engage flange 57 as above noted. These notches operatively engaging the corresponding flanges serve along with the resilient characteristic of the anchors to effectively stabilize said anchors in their several operative positions in the assembly.

From the foregoing description it appears that we have provided anchors for the sash frame and easing which may be manually snapped into effective locking or engaging relationship with the sill, header and jambs and be attached to the building structure to anchor and maintain the sash frame and casing in position in a window opening regardless of the material employed in the building structure.

Thus by manually canting the anchors and applying pressure thereto in assembling, the casing, sash frame and anchors may be installed in minimum time and with minimum effort without the use of tools. When so assembled, the sash frame and casing and anchors will maintain the desired relationships and rigidity when installed in a window opening.
