DOMINICK P. MAMMLLI, OF NEW ORLEANS, LOUISIANA.

WINDOW-LATCH.

specification of Letter Patent.

To all whom t may concer/n.'

Be it known that 1,-DoM1nioK P. Maisi- MnnLr, a citizen of the United States, residing at New Orleans, in the parish o Orleans and State of Louisiana, have invented new and useful Improvements in Window- Latches, of which thefollowing is a specication.y

This invention relates to window latches, and itV has specific reference to a latch f or securely locking the lower sash of a wmdow in position with respect to the window frame.

he invention has for its object to *p roduce a simple and eiective latch of 1mproved construction whereby the bottoni sash. when lowered to its closed position will be effectively secured until released by means provided for the purpose. .20

A further object of the invention is to produce a device of the class described i n which the latch may be releasedto permit a window to be opened by means of a push button, avoiding the use of keys or the like.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists -in the improved construction and novelv arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing hasbeen illustrated a simple and preferred form of the invention, it being, however, understood that no limitation the precise structural details therein exhibited, but that changes, alterations and modifloat-ions within the scope of the claims may be resorted to when desired..

ln the drawing, Figure l is a perspective view showing the sill and the lower portion of a window frame, together with a portion of the bottoni sash, the same having the invention applied thereto. Fig. 2 is a vertical sectional view taken substantially on the line 2-2 in Fig. 1, Fig. 3 is a vertical sectional view similar to Fig,l 2, but enlarged, and showing the bottom sash in locked position. Fig. -Clis a perspective detail view of the latch casing. Fig. 5 is a `perspective detail view of a pivoted latch member. Fig, 6 is a perspective detail view showing the latch engaging catch member which is to be mounted on the bot-tom rail of the bottom sash.

is necessarily made to j threaded, as shown.

Patented May 30, 1916.

Application led January 17, 1916. Serial No. 72,523.

Corresponding parts in the several iigures are denoted by like characters of reference. The sill l5 of the window to which the device is to be applied is provided with a mortise or recess in which the casing or housing 16 of the improved device is mounted, said casing having at its upper edge a flange 17 which is apertured for the passage of fastening members, such as ordinary wood screws 18, the heads of which are preferably countersunk in the Hangs.

The housing includes wall members which for'convenience will be designated as the front and rear wall members 19, 20. The rear wall member 20 is provided on the inner face thereof near the upper edge. of the housing with bearing sleeves 2l for the reception of a. pin or pivot member 22 on which is hingedly supported a latch member consisting of a plate 23 havingr at the upper end thereof a bearing sleeve 2i and a beveled head portion 25 having a shoulder 26. A spring 27 interposed between the plate 23 and the rear wall of the housing serves to force the lower end of the latch member in a. forward direction toward the front wall of the housing. The said front wall is provided near the lower edge thereof with an aperture 27 for the reception of a nipple 28 projecting at one end of a cylindrical socket 29 which by moans of the said nipple is connected with the front wall of the housing, as clearly seen in Figs. 2 and 3, the nipple` being preferably extcr? nally threaded to enable it to be conven iently assembled with the housing. the aperture 27 of -which is correspondingly threaded.

Extending through the nipple 28 and the socket member 29 is a rod 30 having at one end a head 3l which is positioned within the housing 1G in such fashion as to abut on the lower end portion of the latch plate 23. Coiled about the rod 30 within the housing 29 is a spring 82 which is tcnsioned by means of a disk or washer 8B which is in threaded engagement with the rod BO, the outer or forward end of which is screw The tension of the spring 32 is exerted against the washer 33 to' force the rod in a forward or outward direction throu f h a horizontal aperture 3i in the sill l5. A push button is placed in 'threaded engagement with that portion u of the rod which extends beyond the inner face of the sill, and 6 is mounted on the push button.

Secured on the under face of the bottom rail 37 of the bottom sash 38 is a catch member consisting of a plate 39 having a flange 40 provided with apertures 41 for the pas# sage of fastening members, such as ordinary screws. At its lower end the plate 39 has a catch hook 42 adapted to engage with the beveled head 25 of the latch member 23 to secure the bottom lsash in locked position, the parts being protperly proportioned so that when the bottom sash is forcibly moved down to engage the sill, the catch member 39 will enter the housing 16, causing the catch hook 42 to engage beneath the shoulder 26 of the beveled head 25 of the spring projected latch member. In order that the catch member 39 may readily engage and enter into the' housing 16 the said catch member is downwardly beveled, as shown.

an escutcheon plate sill surrounding the of alinement with the housing, it will still enter the same and be guided safely within housing without danger of injury or breakage oi any of the parts.

In order to release the latch so as to permit the bottom sash to be opened it is only necessary to manipulate the push button 35, whereby the rod 30 will be pushed in a rearward or inward directiol, causing the head 31 to engage the springr projected latch plate 23, forcing the latter agalnst the tension of e spring 27 in the direction of the rear wall of the housing and disengaging the shoulder 26 from the hook 42. f

It will be seen that I have produced a very simple and effective window latch which by reason of its construction as herein set forth may be easily and inexpensively installed on any window casing of ordinary construction. i 1

Having thus described the invention, what is claimed as new, is z` 1. In a latch of the character described, a housing open at its upper end and provided with an attaching flange at its upper edge, the rear wall of said housing havmg bearing sleeves on its inner face the upper edge f thereof, a latch member consisting of a plate havl g at its upper end a beveled head and at its upper edge a bearing sleeve, a pin engaging the bearing sleeves on the rear and at the upper edge of the latch p plate, and a spring interposed between the lower portion of the latch plate and the rear wall of the housing.

2. In a latch of the character described, a ousing open at its upper end and provided with an attaching flange at its upper edge, the rear Wall ot said housing having bearhousing, the forward wall of the housing being provided with an e ge; socket member having a. nipple engaging the aperture, a headed bolt extendingthrough thereof, plate having at its upper end a beveled head and at its upper edge a bearing sleeve, a pin engaging the bearing sleeves DOMINICK P. MAMMELLI.
