ADOLF HUNDERT, OF NEW YORK, N. Y.
LOOK FOR WINDOWS.
Application filed November 26, 1913.
To all whom it may concern:
Be it known that I, AnoLr HUNDERT, a subject of the Austro-Hungarian Emperor, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Looks for Windows or the like, of which the following is a specification.
The present invention relates to looks for windows and has for its object to provide a construction that can be easily manipulated and that could not be opened from the outside. It is well known that with the hitherto used locks, where one part, a socket, is secured to the lower cross piece of the upper sash and the other, a horizontally turning bolt, is fulcrumed to the upper cross piece of the lower sash, the lock can be easily opened, by piercing an instrument through the space between the two sashes and turning the second named part out of engagement with the socket.
My device consists of a trigger shaped bolt, which is adapted to be fixed to the lower sash, so as to extend toward a hole provided in one of the side pieces of the upper sash. The bolt is fulcrumed to a handle and extends through a casing in which the handle is pivoted and which is adapted to be fixed to the lower sash. A spring is adapted to lock the bolt in look ing position.
In the accompanying drawing, Figure 1 is a cross section of a window, with the lock applied thereto; Fig. 2 is a longitudinal section of the lock and Fig. 3 is a cross sec tion on line 38 of Fig. 2.
a, 6- denote respectively the upper and lower sashes. The upper sash has a hole 6 in one of its side bars in which'hole a metal socket b may be fitted. Fixed to the upper surface of the cross bar a of the lower sash a near the side where the hole Z) is arranged, is a metal casing c, which is hollow and in the end facing the window has a guide opening 0. The opposite end of the Copies of this patent may be obtained for Specification of Letters Patent.
Patented May 18, 1915.
Serial No. 803,127.
casing is open, as at 0 and fulcrumed in the upper part of the casing, as at cl, is ahandle (Z which has pivoted to it, as at c, a bolt 6 that extends longitudinally through the easing and is loosely guided in said opening 0. Fixed to the bottom of the casing is a bent plate spring f, the upper arm f of which is slightly bent upwardly, as at 7, forming a nose adapted to engage a notch c in the bolt, when the latter is in looking position, as shown in Figs. 1 and 2. l/Vhen the bolt is projected outwardly or toward the window its free end enters the socket b and locks the two sashes.
No access can be had from the outside to the bolt and therefore the opening of the look from the outside is impossible. No force is required to swing the bolt into looking position or unlocked position, whereas a considerable axial pressure on the bolt would be required to displace the bolt should an attempt be made to force the bolt back from the outside by drilling a hole in the woodwork.
What I claim and desire to secure by Letters Patent is:
The combination with window sashes, of a hollow casing fixed to one of the sashes and having a guide opening at one end, a handle fulcrumed at the opposite end of said casing, a bolt pivoted to said handle at a point intermediate between the fulcrum and the free end thereof and inovably extending through said casing and guided in said end opening thereof, a plate spring in said casing having an outwardly projecting nose and engaging a notch of said bolt in looking position and a socket in the other sash engaging the bolt in looking position.
In testimony whereof I affix my signature in presence of two witnesses.
ADOLF HUNDERT.
