MAX PETROVICS, OF NEW YORK, N. Y.
LOOK FOR SWING-SASHES.
esaosa.
To all whom it may concern:
Be it known that 1, MAX Pn'rnovrcs, 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 SwingSashes, of which the following is a specification.
This invention relates to an improved lock for swing-sashes of that type which are used extensively with wire glass panes for factories, ware houses, oifice-buildings and the like, the lock permitting the swing-sash to be opened with great facility, held in position for ventilation or cleaning, and returned and locked automatically into closed position.
In the accompanying drawings, Figure 1 represents a perspective view of a swingsash window with my improved automatic locking device, Fig. 2 is a detail front-elevation showing the locking device at the upper part of the sash on a larger scale, and Fig. 3 is a side elevation of the parts, shown in Fig. 2.
Similar letters of reference indicate corresponding parts throughout the several figures.
Referring to the drawings, a represents the frame of a swing-sash of that type which are used for factories, storage warehouses, oflice and other buildings. The frame a is preferably made of sheet metal, while the pane is made of wire-glass. The swing-sash is pivoted slightly above the center of its height to the window-casing and swung into open position for cleaning or ventilating purposes on fixed pivots Z).
The locking of the swing-sash is accomplished by means of a weighted latch pivoted to ears f on the upper part of the window-casing and adapted to drop by gravity into engagement with a U-shaped catch f that is attached to the upper crossrail of the swing-sash a. A wire cord or chain it is attached to the lower perforated end f of a knuckle 7, said cord or chain being provided at the lower end with a ring it. The upper end of the knuckle f is rounded off so as to engage the lower end of the weighted catch 7. When the swing-sash is to be opened, the chain or cord 72, is pulled in downward direction. This produces the lifting of the knuckle f and the lifting and releasing of the weighted latch 7 from the catch 7, so that the swing-sash is moved Specification of Letters Patent.

Serial No. 547,490.
on its pivots 6 into inclined position for the purpose of ventilating the factory or other building. "When the chain it is released the swing-sash is returned by gravity into closed position, the latch f being also returned by gravity into its former position, and into engagement with the catch f while the knuckle resumes its place under the weighted latch The locking device of the swing-sash is thereby returned to its normal position. The latch 7 may be held in substantially horizontal position by a suitable stop or shoulder such as the weather strip of the window frame as shown in Fig. 3. As in sOme factories the swingsashes are arranged at a considerable height from the floor, the operating chain or cord it has to be made of such a length that the swing-sash can be operated from the floor of the factory.
The pivots of the swing-sash are arranged slightly out of center in such a manner that the lower part of the swing-sash is heavier than the upper part in order to return the sash by gravity into closed position. The pulling of the chain releases the weighted latch f from its catch f and causes by continuing the pulling of the chain the opening of the swing-sash and the holding of the sash in open position, while on the return of the swing-sash into closed position the locking of the weighted latch to its catch is accomplished automatically, and the swing-sash locked in closed position as described.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
The combination, with a swing-sash arranged to be normally held in closed position, of a locking device applied to the upper part of the sash and window and consisting of a base secured to the sash, a pair of perforated members integral with the base and extending away from the sash, a catch-bar integral with the outer ends of said members, and having an outwardlyexposed beveled shoulder, a pair of cars secured to the upper part of the window-casing, a latch pivoted at its inner end between said ears and extending outwardly away from the casing and having a weighted outer end having a downwardly-extending projection having an inwardly-disposed shoulder adapted to engage said outwardlyexposed shoulder, a pin passed through said perforated members, a knuckle fulcrumed I y In testimony, that I claim the foregoing on said pin and having a Weighted outer end as my invention, I have signed my name in adapted to engage under the weighted outer presence of two subscribing Witnesses.
