- and State of Michigan, have invented certaln new and useful Improvements in Auto-- matic Locks for Metallic Windows. of which the following is a specification, reference be ing had therein to the accompanying draw-.
mgs.
The invention relates to metallic window construction in which ventilation is provided through swinging sash sections.
The object of the invention is to provide a simple construction of automatically latching lock, which'permits the closing of the swinging sash and securely locks the same when closed.
In the drawings: Figure 1 is a front elevation of the lock, showing a fragment of the window sash to which it is applied; Fig. 2 is a side elevation thereof; Fig. 3 is a horizontal section. showing the lock in plan; and Figs. 4 and 5 are respectively diagrammatic front and side elevations, showing a stationary sash and ventilator with the locking mechanism applied thereto.
A is the stationary portion of a metallic window sash and B is the swinging sash or ventilator secured therein by suitable pivots (not shown).
C is a. notched brace bar or stay for holding the ventilator section in open position. being pivotallv secured to the latter at D by ear plates E secured to one of the sash bars F.
which is pivotally secured to the swinging or ventilator section so as to be movable in a plane parallel to the plane of the swinging sash. This lever is preferably pivoted to the sash bv being secured between angle plates TI and H. which are secured upon opposite sides of the web portion of the bar F so that their angle flanges are parallel to each other and to the plane of the sash.
T is the pivot pin or bolt for securing the lever between the angle plates H and H.
The lever G is preferably formed with a portion J normally projecting vertically downward from the pivot and terminating in a laterally-extending tapering nose portion K inclined to both the vertical and horizontal planes. Above the pivot the lever G is preferably offset or bent outward at L to giveclearance from the sash, and then extendsat right angles or parallel to the plane of the sash to form an operating. and
gravity-actuated. arm M. The construction is such that the inclined and tapering nose portion K of the lever swings in apath which is intercepted by the upper rail N of the stationary sash section, against which the lower rail 0 of the swinging sash section abuts to form a weather stop. The nose K is, however, so fashioned that upon contacting with the stop rail N it will ride over the same. turning the lever upon the pivot I and lifting the ravity arm M. This will turn the portion bl of the lever upward so as to clear the upper edge of the bar N, upon passing which the weight of the arm M will return the lever. moving the portion swung in a plane parallel to the sash, which permits of a suitable length of lever without projecting the same any considerable distance beyond the plane of the sash. Another advantageis that the latch, when it automatically engages to lock the sash, also has a wedging or drawing effect for tightly closing the same.
What I claim as my invention is:
1. The combination with a swinging window sash, of a stop for said sash, a gravityactuated arm pivotally secured to said sash to swing in a plane parallel thereto, provided with a portion for liftingsaid lever in passing said stop and a portion for wedging engagement with said stop when past the latter.
2. The combination with a swinging window sash and'a stop for said sash, of an automatically latching lever secured to said sash to swing in a plane parallel thereto and adapted to automatically clear said stop in passing the same and to have a wedging engagement with said stop when past the latter.
3. The combination with a swinging window sash and a stop for said sash, of an automatically latching lever seemed to said sash, said lever having a downwardly extending portion exitending into the path of said stop during the closing movement of the sash and parallel to said stop in closed sash and an arm portion extending substantially parallel to the plane of the sash.
4. The combination with a swinging window sash and a stop for said sash, of an automatically latching lever secured to said sash to swing in a plane substantially parallol thereto and adapted to automatically clear said stop in passing same, said lever having one end slightly tapered for a wedging engagement with said stop and its opposite end ofiset outwardly and extending substantially parallel with the sash.
In testimony whereof I affix my signature in presence of two witnesses.
