" Whether used inc'onnection With one'or both This invention relates tol a fastening device adapted to 'be operatively applied ,in
connectionv with a sash, movable panel or other analogous movable member to Which the devicelmay be applicable. Y,
The primary object of the invention is to hold a Window sash, panel or analogous mov-y able member either locked in closed position or in partiallyopen position, and to have y'theimproved fastener of such construction thatl it may Vbe readily reversed 'to engage opposite portions of a sashfor Window frame, panel or other ,movable ymember to hold the .same against movement. y
A further object ofthe'invention is to lprovide Aa fastener-. of' the class specified, which is 'simple in construction and economical'` in'manufacture, the improved device,
sides of' a sash or Window frame, panel or other movable umember, being ,the same in construction, orwhere 'tivo of the improved devices are used, they will be duplicates.
i A" furtherl object fofthednvention is to` provide a fastening device ofthe class speci-y fied Which lmay also serve to eliminate' all vibratory noises or rattling of the Window sash, panel` or other movablemember, and also'to effect a tight joint, particularly of a Window sash With'respect tothe inner and outer stops of a Window frame, to'ezgclude cold air andthereby renderthe 'use of Weather stripsfand` lili@ air-eXcluding means.
A stillfurther object' of the invention is to provide a fastening device of the class specified, Which'may be readily appliedfin operative position Without requiring' any- `special mechanical knowledge, and more.-
over, toprovide a'fastening device which is*` `ofthe devices in full and dotted lines vto il-i lustrate the operationof the same.
Fig.V G'is'a detail perspective view of thepreferred form of the improved fastening device. l 1
Fig. 7 is an elevation of a slightly modi;
fied form of the fastening device;
Fig. 3 is a vieW similar to Fig. 2, showing one, 'of the improved fastening devices in "locking position to prevent `raising of the vc5 y YThe improved fastening deviceis shown applied to aivindow sash, a pair of the devices being illustrated as fastened to the side member. of the sash in Fig. 1but it Will be understood that the said fastening device Willoperate with equal efficiency if ap-f` plied to the inner opposite side portions "of the frame and bindagainst the adjacent-side members of the sash. Furthermore, it mayVv at'times be desirable lto. use only` one of the` V improved devices, and it is 'obvious that the:y invention will not be in the least modified by either a single or double use of theilnproved f device. Y
Structurally, the improved device comprises a flat body member 5, Vof suitable thickness, having the opposite ends 6 and 7 struck 0r bent up at right angles tothe body member in the'form of flanges. These endV flanges are curved in the arcs of. circles struck from the centers A and B inthe preferred form of `.thef device, Vand from the centers C and D in the modified formk shown by Fig.` 7. In the preferred form ofthe fastening devicel as shown by Figs. l to 6, inclusive, the opposite side edges are of'duplicate contour, there being .tWo parallel straight side edge portions intersected at their inner terminals by obtusely-arranged, shorter straight side edge portions 9,- which continue outwardlyi'to the curved outer. surfaces of the flanges 6 and 7, these` curved flanges with the body 5l essentially forming a double'cam for reversible operation. The flanges 6 and` 7 are equidistant from the Vcenter of the lbody 5, and the generall construction of Vthe improved device is such that one standardized form of the same may ln applying the improved device, it will Y be impossible to place the Vsame in a wrong position on fthe side members of the window sash oi' inner opposite sides of the window frame or panel casing, `for the reason that when the device is placed on the casing, it is only necessary to` dispose any one of the straight edges 8 or 9 parallel with the edge of the casing or sash or panel casing, as the case may be, with any point touching the edge of the window frame, sash or casing, and if this mode of application is properly followed, the device will be inproper position for operation. lVhen placed on the right side of the inner portion of the Vwindow frame or side member `of the sash, the device operates as a positive stopfto prevent the sash from being lowered, and when thel device is placed A on tlie le'i't side of the window frame or sash as shown byFig. 1, it operates to hold the window against raising movement, and
bythis means asafety device is provided and also all vibration and rattling noise Vwill be positively eliminated. When the device applied to both the right and left- :15 hand sidesof awindow frame or sash in prop-er operative position, a slight pressure thereon, either downwardly or upwardly as `ithe'casc may be, will immovably hold the sash or panel in place. When the window sash is 40 closed, as in cold or windyweather, thel iin` proved device is operated on both sidesto set up a binding` act-ion relatively to the window sash and Vseal the window or tightly 'hold the same in such manner as to obstruct Vall ingress of cold air 4and dust, and by this means the use of weather stripping is obviated. Vhen the window is closed and has the improved device applied to opposite sides thereof as shown in Fig. l, a sealing of the window sash to obstruct ingress of cold air and dust may be effectively obtained by. first pressing outwardly on the sash and then operating the device to lock the sash against movement On the other hand, when the improved devices are applied to thie inner opposing sides of the inner part of the frame or window casing, the pressure of the device on the side portions of `the sash will bepeXerted in an outward direction, either to lock the sash against upward and downward movement, or, when the sash is closed, to sealv the same, as above specified. n The curved surfaces or opposed cam `edges provided by the curved flanges 6 and 7 will,
"tinuing' outwardly to the Vouter surface of not mar the window sash or the inner opposing sides of the window casing or frame, as
`the device need only exert a slight binding be made invarious sizes, but for all practical purposes a standardized size will be adopted Y and manufactured and have such roportions asto renderthe device practical-,for the purpose for which it has been devised.
T e nn roved fastening device is secured in applie position through the medium of one screw 10, which is passedthrough anopening l1 in the intermediate portion of the body 5, thesaidscrew being of such construction that it firmly holds the devicein association with the window sash or innerl side of the window `frame and at thefsame time permits a re uisite:` pivotal or'swinging movement of the astening device thereon.v
In themodified `Structure,shown by Fig. 7 the features. are `essentially the same'asYA those,:described in connectionrwith the pre`` vferred form,- the diierencebeing in this instance'that one extremity 5*? of the body 5 ,serves as a weight gravitating A feature,v owing `to the eccentricity of thev openin 12V corresponding to the opening l1 in the form` shown by Fig. 6. Furthermore, theonesde edge 13 extends in a straight'line almost fully from the flan e 6 to the iange 7, there being a short angular straightedge 14' conthe flange 7. The opposite" side edge of this modified formis more nearly like the struc`` ture shown by 7 Vand comprises a straight edge 15 parallel with the edge 13` v and an angular straight ed e 16, continuing from the edge 15 outwar ly to the outeif surface of the flange 6. f
l The operation of this modified structure is essentially the sare as that heretofore described in connection with the referred form and both forms embody Yt e essential features .of the invention, namely, the flat body 5, pivotally mounted and having opposite side edges composed of Vstrai ht lines arranged at an angle to each Vot er and presenting two curved cam flangesfor engaging the window sash or adjacent ortion of the window frame or correspon ing parts of other `movable and. supporting strlctures with which the device may be use V What is claimed as new is: A reversible fastener for windows, con sisting of a fiat body formed of one piece of material and having the Vopposite ends provided with curved vflanges rojected solely from the outer` side of the ody `and struck from two different centers and whose outer sides present opposing eccentric cani portions at obtuse angles and which latter faces extending reversely over the center of edge portions terminate at the ends of said 10 the body, and also having opposite straight flanges opposite the outer terminals of the parallel side edge guiding portions extendsaid parallel side edge portions. ing part Way the length of the fastener and y InV testimony whereof I have hereunto set each terminating at one end with reverse my hand.
