Leave June 6, 1933'. J. R. McALEAVEY WINDOW SASH FASTENER I Filed Feb. 6, 1952 Patented June 6, 1933 PATENT OFFICE JOHN R. MCALEAVEY, F MILWAUKEE, WISCONSIN WINDOW SASH, FASTENER Application filed February 6,1932. Serial No. 591,271. a

This invention relates to improvements in window sash fasteners.

One of the objects of the present invention is the provision of an improved type of window sash fastener adapted to be applied to i the upper sash of a window and provided with a locking bolt adapted to beiprojected out over theupper portionof the lower sash, whereby to prevent either the lower sash from being raised, or the upper sash from being lowered, so that when the fastener is in operative position, the sash members are retained against movement. a

Another object of my invention is the provision of a sash fastener comprising a locking bolt carried by the upper sash of awindow and adapted to benormally projected by a spring into locking position above thelower sash with means for restrictingthe outward movement of the locking bolt, releasable means being provided for retaining the locking bolt in a retracted, inoperative position.

i A further object of the present invention is the provision of a sash fastener which in- 5 cludes a housing having a spring-actuated locking bolt therein and adapted to be projected from one side of the housing, together with a pivoted catch member for retaining the boltin an inoperative position, the catch being so engaged with the bolt, thatmanual pressureon the catch member will release the bolt to permit the same to be moved to operative position.

A still further object of my invention is the provision of a novel sash fastener having means incorporated therewith, whereby the sashes can be held against movement in a completely closedposition, or against further opening movement in a partially raised position, so as topermit ventilation of a room. 1 With these and other objects in view, the invention consists in novel construction, ar- (rangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawing, in which:

'HF'gure 1 isa fragmentary front elevation of a window showing my improved sash fastener incorporated therewith, parts of the tener, showing the bolt in its projected operainner end of the bolt 20 can be provided with' view being shown broken away and in section. 7

Figure 2 is a vertical section taken on the line 22 of Figure 1, lookingin the direction of the arrows showing the application of my J55 fastenerto the upper Window sash.

Figure 3 is a detailed sectional view through the lower portion of the sash fasframe having slidably mounted therein the upper andlower window sashes 11 and 12. The window frame 10 and the sashes 11 and 12 are of the ordinary or any preferred construction, and the window has been shown to illustrate the use of my improved sash fastener 15. V j

My sash fastener 15 comprises a face plate 16 having formed thereon, adjacent to its opposite ends, the casings 17 and 18 for the' reception of the sash fastener bolts, as will be hereinafter more fully described. The fastener l5lis associated with one of the side rails of the upper sash 11, and its rail is mortised to receive the casings 17 and 18, as is clearly shown in Figure 5 of the drawing. The lower end of the base plate 16 terminates adjacent to the bottom rail of the upper sash, and the face plate 16 can be set into thelower rail, if so desired.

Suitable openings can be formed in the "face plate 16, so as to permit the fastener to be attached tothe window sash, by the use of suitable elements 19.

Each .of the casings 17 and 18 have slid-' ably mounted therein in the lockingbolt 20. This bolt is normally urged outwardly of the casing over the lower sash by means of an expansion coil spring 21. If preferred, the

a longitudinally extending bore for receiving one end of the spring 21. In order to limit the outward sliding movement of the bolt 20, the same is provided with an arcuate ear or lug 22, which is disposed in the path of a stop lug 23 formed on the inner face of the plate 16. The lug orear 22 also serves as a means for preventing outward movement of the bolt to an operative position, when the ear is engaged by themovable actuating dog 24. The movable actuating dog 24 is rockably mounted at its upper end on a pin 25 arranged within the casing. At a point intermediate its ends the dog is provided with a finger piece 26 which projects through an opening 27 formed in the base plate 16. The free end of the dog is normally urged toward the face plate by means of a spring 28, which spring is coiled about the pivot pin 25. The extreme lower end of the dog normally rests in the rear of the ear 22 when the bolt is in its retracted position, as shown in Figure 5 of the drawing.

When it is desired to release the bolt, it is merely necessary to press inwardly on the finger piece 26, which will rock the dog 24 on its pivot 25 against the tension of the spring 28. The inward movement of the dog 24 swings the lower end thereof over the ear 22, which will release the bolt and allow the same to be moved to its projected position by its spring 21. The projected position of the bolt is clearly shown in Figure 3 of the drawi vhen it is desired to hold the sashes in their completely closed position, the bolt 20 carried by the lower casing 18 is projected, and this bolt will then lie directly above the top rail of the lower sash 20. This will prevent the raising of the lower sash and the lowering .of the upper sash.

hen it is desired to move the sashes to a partly raised position, for the purpose of ventilation, the bolt 20 in the upper casing 17 is released. This will allow a limited opening movement of the sashes, but this movement is restricted by'the bolt and complete opening movement of the sashes is prevented. V

The sash fastener is arranged on the inner face of the window and is so disposed that theoperation thereof from the outside is impossible, which renders the fastener substantially burglar-proof. I

The top rail of the lowersash 20 can be pro vided with a wear and strike plate 29 against which the bolts 20 can rest, so as to prevent injury to the lower sash by said bolts.

My invention is capable of slight modification, and in Figure 4 I have illustrated another form of the invention. In this form an operating dog 30 is provided, which can be loosely mounted within the lock casing. This dog carries a finger piece 31 which projects through the front wall of thecasing,

and the upper end of the dog can be provided with bearing ears 32. The lower end of the dog is adapted to engage the projection 33 on a lock bolt 34 for normally preventing outward movement of the lock bolt. A single leaf spring 35 is provided for the purpose of urging both the bolt 34, and the dog 30, to their normal operative positions. It is to be noted that the leaf spring 35 is bent back upon itselfso that an intermediate portion thereof will bear against'the fastener casing, and so that the opposite ends of the same can engage the bolt and dog respectively.

This form of my fastener operates in exact ly the same manner as the preferred form previously described, and, obviously, by pressing in on the finger-piece 31 the dog will be moved beyond the projection 83, allowing the bolt to move outwardly under the influence of the spring.

In both the forms of my invention, when it is desiredto move the bolt back to its retracted, inoperative position, it is merely necessary to press in on the bolt itself, and the curved projection on the bolt will move the dog inwardly against the influence of the spring and the dog will ride over the surface of the projection and move in front thereof.

From the foregoing description, it can be seen that I have provided an exceptionally simple and durable form of sash fastener, which can be readily applied to a window, and which is substantially burglar-proof.

Changes in details may be made without departing from the spirit or scope of this invention, but what I claim as new is:

1. A sash fastener including a housing having a removable cover comprising one wall thereof, one wall of the housing having spaced openings, a spring-actuated locking bolt normally projected through one of said openings, means for limiting the outward movement of said bolt, a shoulder atone side of the bolt adjacent the inner end thereof, a pivoted catch within the housing and 1' adapted to engage the shoulder to retain the bolt against movement and in a retracted position, and a thumb piece carried by the catch and projecting through the second opening whereby pressure upon the thumb' piece will actuate the catch to release the locking bolt.

2. A sash fastener comprising a housing having spaced openings therein, a lock bolt slidably mounted in the casing, spring means normally urging the bolt out of one of the openings to a projected position, a shoulder on the inner end of the bolt, a catch pivoted at one end in said housing, the opposite end of the catch being disposed in the path of the shoulder for holding the bolt against movement to a pro ected position, means limiting swlnging movement of the catch in one direction, and a theimb piece slidably mounted in the other opening of the casing engaging the catch whereby pressure upon said thumb piece will swing the catch to move the same past the shoulder of the lock bolt.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wiscousin.
