Description

No 848,393. PATENTED MAR. 26, 1907. M PETROVIUS LOCK FOR: SWING SASHES. APPLICATION FILED MAY 9. 1906.
MAX PETROT ICQoF NEW YORK, N. Y.
LOCK FOR SWING-SASHES.
Specification of Letters Patent.
Patented March 26, 1907.
Application filed May 9, 1906. Serial No. 315,867.
To all whom it may concern.-
Be it known that 1, MAX PETROVIOS, a citizen of the Kingdom of Hungary, residing in New York, in the borough of Manhattan, county and State of New York, have invented certain new and useful Improvements in Looks for Swing-Sashes, of which the following is a specification.
The object of this invention is to furnish an improved lock for the socalled swingsashes which are used extensively, in connection with wire-glass, for factories, offices,v &c., so that the sash can be opened with great facility, held in any desired position, returned into closed position, and then looked automatically in the closed position and for this purpose the invention consists of a swing-sash which is pivoted intermediately of its height and provided at the lower part with a weighted latch and at the upper part with a guide-pulley, a chain extending from the latch over the guide-pulley to a suitable support on the window-casing, and a catch on the windowsill, with which the weighted latch interlocks when the sash is permitted to swing into closed position.
In the accompanying drawings, Figure 1 represents a perspective view of a swing sash window with my improved lock attached thereto, showing it in closed position. Fig. 2 is a perspective view showing the swing-sash in open position. Fig. 8 is a detail perspective view of the locking-latch of the swingsash. Fig. 4 is a vertical transverse section of the same, and Fig. 5 is a detail perspective view of the guide-pulley at the upper part of the swing-sash.
Similar letters of reference indicate corresponding parts in the difierent figures of the drawings.
Referring to the drawings, (t represents the frame of a swing-sash window, such as are used for ofiice-buildings, factories, and the like, which frame is'preferably made of metal, while the pane is made of wire-glass. The swing-sash is pivoted midway of its height to the window-frame and swung into open position on the pivots by releasing the locking device of the same. This locking device consists of a weighted latch Z, which is pivoted to an angular flange I), attached to the lower cross-rail 0 of the sash-frame, the weighted latch interlocking by its inclined recess with an inclined catch 0, that is attached to the window-sill c. The outer end of the weight ed latch Z has a transverse perforation to which is applied a chain f, which extends in vertical direction to the upper rail of the swing-sash and is conducted over a roller or pulley f, which is supported in a suitable keeper f attached to the upper rail of the swing-sash, said chain being then extended in downward direction onto a hook 1 to which the lower end of the chain is attached.
The pivots of the swing-sash are arranged slightly out of center, so that the lower part of the swing-sash is heavier than the upper part in order to permit the return of the sash by gravity into closed position. The weight of the lower part of the sash is increased by the weighted latch, so that as soon as the chain is released from the hook f 3 the swingsash is returned into vertical and closed position, while simultaneously the weighted latch engages the catch 0 and interlocks with the same, holding thereby the window in closed position. For opening the window the chain f is removed from the hook f then pulled in downward direction, so as to lift the latch clear of the catch 0. The unlocking of the swing-sash, as well as the locking of the same in closed position, are accomplished by the chain without requiring any other manipulation, as the pulling of the chain releases the weighted latch from the catch and opens the swing-sash, while on the return of the sash into closed position the locking of the catch is accomplished automatically and the swingsash locked in closed position.
My improved lock for swing-sashes has the advantages, first, that it can be opened or closed by means of the chain even when the same is of such height as not to be reached by hand; second, that the weighted lockinglatch assists in the closing and automatic locking of the window without any manipulation of the swingsash, and, lastly, that in case of fire all the windows can be closed quickly and locked effectively, so that protection against the spread of the fire is obtained.
