WINDOW FASTENER. AAAAAAA TIOH rILn'n my. a. 00000 4.

EEEEEEEEEEEE 1- ADOLPH ROSENBERG, OF CHICAGO, ILLINOIS. WINDOW-FAS-TENER.

To aZZ whom u: may concern:

Be it known that I, ADoLrH Rosnnnnno a citizen of the United States, residing at 4139 Calumet avenue, Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Window- Fasteners, of which the following is a specification.

My invention relates particularly to window-fastening devices by means of'whieh the window may be secured either in a whollyv closed or partially-closed position.

My primary object is to provide a simple and inexpensive fastening which will serve so to secure a window asto prevent the entrance of unauthorized parties, while permitting the window. to be kept partially open for ventilation purposes.

The invention is illustrated in the accompanying drawings, in which Figure'l represents a broken inner view of the upper and lower sashes of a Window Fig. 2, a vertical section taken as indicated at line 2 of Fig. 1; Fig. 3, a plan section taken as indicated at line 3 of Fig. 1; Fig. 4., a view similar to Fig. 2, but showing the window opened slightly; Fig. 5, a perspective view of the fastener member for the upper windowsash; Fig.6, a view similar to Fig. 1 and showing a modification of the fastener; Fig.

- 7, a section at line 7 of Fig. 6; Fig. 8, a section at line 8 of Fig. 6; Fig. 9, a perspective view of the upper fastener member shown in Fig. 6, and Fig. 10 a perspective view of thelower fastener member shown in Fig. 6.

In the preferred construct-ion, which is shown in Figs. 1 to 5, inclusive, A represents the upper sash of a window; B, the lower sash; O, a vertically-disposed fastener member attached to the upper sash, and D a horizontally-disposed fastener member attached tothe lower sash.

The member. 0 is an elongated member, which may be a stamping or a casting, said member being dished to provide side flanges c and a bottom flange 0, bearing against the sash, and a raised wall c parallel with the sash and supplied with a vertical slot 0 at the lower end of which is a relatively large opening 0 at the lower end of which is attached a tongue 0 which slopes inwardly and upwardly and contacts at its free end with the sash. The Wall 0 slopes inwardly at its ,upper end to meet the sash, as shown, and 1s Specification of Letters Patent.

provided with screw-holes-c, which receive screws 0 serving to secure the member to the sash.

The member D comprises acasing (i, having a horizontalibore and provided with attaching-flanges d, a bolt 1 and a spring (i confined between a shoulder on the bolt and the outer end of the casing. The inner end of the casing is open, and the normally projecting head of the bolt is provided with lateral vertical grooves (1*, which engage with the Walls of the slot 0 when the window is partially open, as shown in Fig. 4. At ,the opposite endthe bolt has a small smooth stem d which projects through a perforation at the outer end of the casing.

The manner of use will be readily understood from the foregoing detailed description. hen the window is wholly closed, the bolt projects beneath the bottom of the member 0 and locks the sashes against relative movement. When it is desired to open the window, the bolt is retracted by means of the stem d, which permits relative movement of the sashes. After the initial movement of opening the bolt is released and enters the perforation c whereupon further movement causes the bolt and member'C to become interlockingly engaged. The relative movement of the sashes in opening the window is limited by the engagement of the bolt with the upper end of the slot 0 which constitutes a locking-shoulder, and it is noteworthythat the bolt cannot be disengaged from the upper fastener member for keeper except by practically closing the window. The importance of this lies in the fact that it is im-, possible for a burglar to tamper with the fastener, as by reaching through above the upper sash or below the lower sash and employingan implement to retract the bolt. Moreover, the small stem employed as a handle for the bolt enhances the diflicultyof with drawing the bolt for any one not within the room.

In the construction shown in Figs. 6' to- 9, inclusive, C represents the upper fastener member or keeper, and D the lower fastenermember, equipped with a bolt or spring-held stop. In this case the keeper has the general conformation of the keeper C, but instead of having provision for continuous interlocking connection with the bolt; is provided with a series of perforations or sockets f for recelving said bolt, according to the relatlve positions of the sashes. The sockets are trlangular-sha ed, and the head of the bolt is corresponding yshaped and also grooved, as shown at f, to interlockingly engage the sockets. At the 'upper and intermediate sockets are inclined tongues f upon which the bolt may ride in entering the sockets.

In both constructions, it will be observed, the bolt may be readily disconnected from 1ts keeper by a person within the room to P61111113 the window to be opened wide, and in the closing movement of the window the bolt will ride over the inclinations at the upper end of the keeper and at the socket or sock ets and finally securely engage the lowermost locking-shoulder of the keeper.

Preferably the upper fastener member is secured upon the inner surface of the upper sash, as shown, and the lower sash is provided with a vertical groove g to accommodate said member. It will be understood, however, that the upper fastener member may be set into a suitable socket in the upper sash, and the groove 9 may then be omitted.

It will be understood that changes in form I and materials may be made and thatthe ar- "rangement of parts may be varied without departure from my invention. I Hence I de s 1re to be understood .as intending no undue hmitation by the particularity of the de scription given.
