WINDOW LOCK :Filed Aug. 22, 194e Patented `an. 9, 1951 UNITED STATES PATENT' 0F WINDOW LOCK Carl G. Carlson, Clu'cago, Ill. Application August'ZZ, 1946,' Serial No. 692,266
2 Claims.
' Another object is to provide window locking. means which is automatically retracted fromA locking position, whenever the rotatable member ofthe sash lock is moved toits locked position. 1 Another object' is to provide window locking means, having an extensible and? contractible locking member, whereby vthe lock may be adapt ed for windows ofk several widths, within certain given limits.
` Other objects and advantages will occur inthe course of this specicationand with said objects and advantagesin View, this invention consists in the several novel features of construction, arrangement and combination of parts hereinafter fully set forth and more particularly defined in the appended claims.
The invention is clearly illustrated in the drawing accompanying this specification, inrwhoh:
Fig. l is a view partly in pla-n and partly in horizontal Section through theupper sash and one of the window frame members, illustrating a Simple thereto;
Fig. 2 is a vertical crosssection taken on the line 2 2 of Fig. l, andr I Fig; is a view partly `in side eleva-tion and partly 'infverticaL longitudinalsection taken on the line ofFig. l'.
Referring to said drawing, which is merely illustrative of a simple embodiment of the invention, the reference character lll designates the upper sash, and ll the Ylower sash of a window, and l2 designates a sash lock of common and weil known construction. The member i3 of the sash lock is secured to the lower rail or" the upper sash as by screws and the rotatable cam member I 4 is secured to the upper rail of the lower sash by a plate ltd fastened to the sash by screws, and said cam member is formed with a cam ilange l5 which may be turned under a hook member It on the sash lock member It to lock the two sashes together. The cam member I4 has a handle or finger piece il by which it is rotated. The exact construction of the sash lock illustrated is immaterial to the present invention, broadly considered, as long as it includes a rotatable member which can function as means for 5 actuating the locking means disclosed herein.
sash, or the upper and formv of the present invention appiiedthe lower sash from being raised or lowered-fromV any given open position.
On the other end of-` the rod v head 23 having an upright cam-flange '24which is arranged to be encountered by the handle l' of the cam member itof the sash loeli when ever the' cam member is turned to its fully unlocked position, and as a result theerod 2i? isv moved in a directiontowardsthewindow frame bringing the blocker foot 22 into frictional con-- tact. therewith. A coiled compression spring 25 surrounds the rod 2? and' isinterposed between an enlarged part ofv the rod and an end wall 2l of' the guide memberlt; and functions-toyield'- ab'ly `thrust therod. toward the cam` member Mi be engaged by the Yhandle lill 'ofV said. cam mem-f ber whenever the' latter isturnedto its unlockedpostion.
l The part 28' of the rod 2G may be-of square-or f I non-circular crossseotion and slides in a corr-ee' spondingly shapedfl-hole man end wall' of the guide member i3; whereby the rod is kept from turning so that the' head 23 will always remainL in upright position tovbe engaged by the handle' Vl of thel cam member 'ofiit'he'sash lock.
The guide member I8 may be in the form of a housing to enclose the coiled spring 25, and the rod 2l] may be secured to the enlargement 26 thereof by means of a threaded connection between the two members.
For locking the upper sash as Well as the lower sash, the rod 26 is provided with a branch rod 28, secured thereto as by a tting 28a and said branch rod extends at an angle to the main rod toward the adjacent stile of the upper sash, and on the end of said branch may be secured a block 2S also preferably composed of rubber or other resilient material which is impinged against said stile whenever the rod is moved toward the window frame.
When both blocks 22, 29 are impinged, one against the window frame and one against theV stile of the upper sash, neither sash can be raised 5 or lowered from any given open position.
the window frame.
is secured a cam position to` in sections, one section 30 telescoping into the other section 3|, and secured therein byV a set screw 32 which is threaded in the outer section and is screwed up against the inner section to fasten the two together in any position of adjustment, thereby accommodating the device to windows of various widths.
In use, when the sash lock is locked the handle I1 occupies the position shown in dotted lines in Fig. 1, and the spring 25 yieldably holds the blocks 22, 29, spaced from the window frame and stile of the upper sash permitting either sash to be raised or lowered.
When the sash lock is partially unlocked, either sash can be partly opened, and by fully unlocking the sash lock and therewith swinging its handle into engagement with the head 23 of the rod 20, the latter is thrust toward the window frame and the two blocks 22, 29 are impinged, one against the window frame and one against the stile of the upper sash, thereby locking both sashes against movement.
1f desired, the rubber blocks may be omitted and the ends of the rod and its branch rod may engage directly with the window frame and stile of the upper sash or may engage in sockets formed therein.
Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence, I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.
What I claim as new and desire to secure by Letters Patent is:
. 1. A sash lock adapted to be mounted on a double sash window structure provided with a window jamb and having a rotatable latch member on a rail of the lower sash for locking the two sashes in closed relation. comprising a bracket adapted to be mounted on the lower sash adjacent to said latch member, a rod, one end o which is slidably mounted in said bracket, said rod being adapted to extend horizontally along the rail of the lower sash to operatively engage the window jamb in the latched position of the rod, a head on the'end of said rod adjacent said bracket adapted to be positioned in the path'k of and engageable with said latch member when the latter is in unlocked position, said head also in the unlatched position of the latch member adapted to move said rod outwardly toward the window jamb of the window structure, resil- 4 ient means associated with said rod and bracket operative to urge said head toward said latch member, a second bracket in which said rod is slidably carried adapted to be Vmounted on said two sashes in closed relation,
the outer end of said rod, and means on the outer end of said rod for engagement with said window jamb, in the outer position of said rod, for preventing movement of the lower sash relative to said jamb.
2. A sash lock adapted to be mounted on a double sash window structure provided with a window jamb and having a rotatable latch member on a rail of the lower sash for locking the comprising a bracket adapted to be mounted on the lower sash adjacent to said latch member, a rod, one end of which is slidably mounted in said bracket, said rod being adapted to extend horizontally along the rail of the lower sash to operatively engage the window jamb in the latched position of the rod, a head on the end of said rod adjacent said bracket adapted to be positioned in the path of and engageable with said latch member when the latter is in unlocked position, said head also in the unlatched position of the latch member adapted to move said rod outwardly toward the window jamb, resilient means associated with said rod and bracket operative to urge said head toward 'said latch member, a second bracket in which said rod is slidably carried adapted to be mounted on said lower sash adjacent the outer end of said rod, means on the outer end of said rod for engagement with said window jamb, in the outer position of said rod, for preventing movement of the lower sash relative to said jamb. an extension secured at one end to said rod and extending angularly outward therefrom toward an adjacent stile of the upper sash, and means carried by the free end of said stile of the extension engageable with said upper sash for preventing relative movement between said sashes.
