Patented Jan. 13, 1953 WINDOW SASH CLAMPING DEVICE Dewitt Tappan, Irondequoit, N. Y., assignor to Ada I. Tappan, Irondequoit, N. Y.
Application July 24, 1950, Serial No. 175,580
3 Claims. (Cl. 292140) This invention relates to a window sash clamping device for securing a window sash or the like in any desired position for safety and ventilation.
An object of the present invention is to provide a window sash clamping device that permits opening a window by lowering the upper sash, or by raising the lower sash, or by both, and that will secure both sash against rattling or movement.
Another object of the present invention is to provide a window sash clamping device that presents a liberal clamping area to the surface of the sash against which the clamping pressure is applied and thereby avoid marring the sash surface.
A further object of the present invention is to provide a window sash clamping device that secures the upper and lower sash to each other and locks them together so that the selected total opening cannot be increased by forceable movement of both sash together from the outside of the window and thereby permit undesired entry through the window.
A still further object of the present invention is to provide a window sash clamping device with a minimum number of parts.
Still another object of the present invention is to provide a window sash clamping devic with removable operating means thereby preventing children or unauthorized persons from changing the size of the opening.
Other objects, purposes and characteristic features of the present invention will be in part obvious from the accompanying drawings, and in part pointed out as the description progresses.
In considering the present invention in detail reference will be made to the accompanying drawings in which like reference characters are used to designate corresponding parts in the various figures and in which:
Fig. 1 is a sectional view of a portion of a window and the sash clamping device taken along the line I-l in Fig. 2 drawn to a reduced scale;
Fig. 2 is a plan view of the device attached to the upper cross rail of the lower sash of a window and applying clamping pressure against the vertical stile of the upper sash with the stile, jamb, parting strip and stop shown in section as viewed from the line 2-2 of Fig. 1;
Fig. 3 is a sectional view taken along the line 33 of Fig. 2;
Fig. 4 is a sectional view taken along the line 4-4 of Fig. 6;
Fig. 5 is a front elevation;
Fig. 6 is a plan view with the clamping member retracted;
Fig. 7 is a sectional view taken along the line 7-1 of Fig. 6;
Fig. 8 is a sectional view taken along the 1ine 88 of Fig. 7; v
Fig. 9 is a plan view of an alternate construction with the operating lever removed, and
Fig. 10 is a sectional view taken along th line ID-10 of Fig. 9 as it would appear if the operating lever were assembled.
In Figs. 1 and 2 are shown parts of a conventional window frame and window sash with the present invention applied thereto. l is the side piece of a window frame normally known as the jamb, 2 is the facing, 3 is the blind seat, 4 is the parting strip and 5 is the stop of the window frame, 6 is the cross rail of the upper sash, I is the upper sash glass, 8 is the stile of the upper sash, and 9 is the cross rail of the lower sash.
The window sash clamping device as embodied in the structure shown attached to the sash in operating position in Figs. 1 and 2 comprises two parts or members only exclusive of the fastening screws which also act as parts of the device. In this embodiment part No. 10 is the clamping member and part No. 11 is the operating cam. In the alternate structure, Figs. 9 and 10, part No. 16 is used instead of part No. 11 and an added part No. 17 is used. The following description applies to either structure except where the difference is pointed out.
The clamping member I [I is preferably constructed of sheet metal and is roughly an L- shaped piece before bending. It has a round hole suitable to serve as a bearing at the juncture of the arms of the L, and slots [8, Figs. 2 and 6, formed parallel to the long arm'of the L in suitable position to leave a flat pressure pad [9 after the short arm of the L is folded: back to form a retaining lip 20. This structure is shown in Figs. 6 and 8. At each end of these slots 2. portion of the metal is left to secure the pad l9 and the lip 26 to the body of the member If). This securing portion being reduced in cross section permits the lip 20 to spring out slightly to admit the cam H for assembly.
Cam H is also preferably constructed of sheet metal of a thickness similar to that of member H). In the structure shown in Fig. 2 it has an arm 2| terminating in a flat upturned portion 22 suitable for turning the cam on its pintle. The body portion of the cam is circular in form except that portion forming the operating arm. Concentric with the outer periphery a disk 23, of suitable diameter to fit into the bearing in part I0, is punched out for a distance about equal to or slightly more than the thickness of the member IO but left secured to the body portion by spokelike portions 24 shown in Figs. 2 and 6 and in section in Figs. 7 and 10. At l5, Fig. 6, a hole is formed offset from the center and eccentric to the circumference of the disk for mounting the cam H directly on the top rail of the lower sash by means of screw l3. the body. of which serves as a pintle on which cam ll rotatesas shown in Figs. 2 and 3. The outer periphery of cam H is of suitable size to bear against the pressure pad" H] as the outer surface of disk 23 rotates. in its bearing in member I 0. Thus it will be notedthat cam H has two laterallydisposedperipheries,
concentric with each other but eccentrieto the.
mounting screw and pintle 13, one of which bears against the pressure pad 19 andthe other-on the inner bearing surface of the hole in partxlhboth of which apply effective; clamping pressure.
An angular slot25 is formedin the. long arm of the clamping member A screw l2 serves tosecurepart I ii to the upper surface of the top rail of the lower sash and also to actasa guide on which part. ldisfree to slide back and forth Within the. limits of the slot 25. InFig. 2 the: window sash clamping device is shown in fulll'line'sin the position it is in when applying pressure against the side. stile oil the upper window sash. In broken linesitis shown in its retracted. position. It willibenotedthat'the-move ment. off the clampingmember is angular with respect tothe-window sash and that the angularity'correspondsto. that of slot 2 5. Thus the angular slot 25 and screw 12' serve to maintain the pressure pad I91 parallel' to the surface of the. upper sash stile 8 sothat thesurfaceof the same is not unduly marred by the window sash clamping; device...
IrrEig. l are shown screws 14 insertedatspaced intervals into the-uppersash. stile 8 and .so placed as tov be in thepathof thepressurepad 19 as the window sash are operated inothe window frame: The functionof these'screws is to form positive; stops toprevent forceable opening of the window from. the outside by slipping the pressure pad along the surface of. the upper sash'stile.
In-oper-ation, after the window sash clamping device has been properly attached,. the cam is rotated by means of the pad 22-, or the-operating lever H, in a direction to cause the clamping member In to. travel toward the. stile of the upper sash and apply sufficient pressure against the upper sash to hold both sash in the selected positions To. releasethe clamping pressure the cam isrotated' in the-opposite. direction;
In the. alternate construction, Figs. 9 and 10, cam. I! withits integral arm 2! has. been replaced by' cam 16 which is the sameas cam. H except that the integral arm has been removed and a-socketZfiformed to admit a removable operating lever N. This construction provides a window sash clamping device wherein the operating means maybe removed and placed out of reach of children or other unauthorized persons. Otherwise this alternate constructionis the same as that heretofore described.
From-the foregoing it will lie-seen that I have provided a new and useful window'sashclamping device that permitsasash adjustment to give a selected window opening at the top, at the bottom, or both,- the operation ofwhichdoes not unduly mar the sash surface, is simple in structure, easy to. operate, andeconomicaL to manufacture.
While the invention has been described with reference to the structural details disclosed, it is not confined to this particular embodiment, and the application is intended to cover any modification or departures coming within the purposes of the improvements and the scope of the following claims.
