ALFRED H. NEWIPHER, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE ADAMS & WEST- LAKE COMPANY, A CORPORATION OF ILLINOIS.

SASH-FASTENER.

Specification of Letters Patent.

Patented May 18, 1915.

To all whom it may concern Be it known that I, ALFRED I-I. NEWPHER, a citizen of the United States, and resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Sash- Fasteners, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The object of the invention is to provide improved means for fastening the window either when closed or open and it consists of the parts and arrangement of parts as hereinafter described and as illustrated in the accompanying drawings, in which- Figure 1 is a front elevation of a window, some of the parts being broken away; Fig. 2 is a sectional view on the line 22 of Fig. 1, some of the parts being broken away; Fig. 3 is a detail of one form of lock which may be used; and Fig. 4 is a sectional detail showing the detent for the locking bolt.

A portion of a window frame is represented at 10 and a sliding sash mounted therein is shown at 11, this sash running between stops 12, 13. To the inner bearing face on the outer stop 12 there is secured a metal strip 14, which, at intervals, is offset outwardly, that is to say, away from the face of the sash, as shown at 15, 16, the stop 12, being recessed to receive such ofiset portions. The offsets 15, 16 are inclined from their lower ends to a shoulder at their upper en s.

The latch 17 shown in Figs. 1 and 3 is of ordinary form, being provided with a spring advanced reciprocating bolt 18 and a bolt actuating lever 19. This latch is secured to the outer face of the sash, its bolt 18 being in. line with the body portion of the strip 14 and hence will enter the recess in the offset 15, 16. The shoulder at the upper end of each of these recesses will prevent the raising of the window without first withdrawing the bolt. When the bolt is within one of these recesses the weight of the sash will carry it toward the bottom thereof and the inclined wall of therecess will have the eifect of camming the sash over against the inner stop 13 and thus prevent rattling. Preferably the strip 14 does not extend to the top of the sash when the latter is closed and above it a leaf spring 20 is housed within a pocket in the inner face of the stop 12 and bears against the sash urging it toward the stop 13 and preventing rattling. Preferably, also, a wear plate 21 is secured to the outer face of the side rail of the sash to make contact with the plate 14 and the spring 20. As the sash is raised and lowered the end of the bolt 18 will run on the edge of the strip 14, which may extend slightly beyond the face of the stop, and the marring of the paint is thus prevented.

If desired, the locking mechanism thus far described may be applied to both sides of the window, or, if omitted at one side, as shown in Fig. 1, there may be used an antirattling device, consisting of a metal plate 22 located between the sash and the outer stop 23 and urged toward the sash by springs, such as 24, 25, 26.

The offset 15 at the lower end of the strip 14 is so disposed as to permit the sash to be raised slightly without withdrawing the bolt, and in order to prevent any unwarranted movement of the sash asupplemental looking shoulder for engagement by the bolt when the sash is entirely closed is provided. This shoulder may be formed of a leaf spring 35 secured by a rivet at its upper end, its lower end fitting loosely through an aperture in the inclined wall of the offset 15.

I claim as my invention,

1. In a window, in combination, a casing having stops, the inner face of one of the stops having recesses decreasing in depth downwardly, a sash slidable between the stops, and a reciprocable bolt carried by the sash and adapted to project into the recesses, an inwardly bowing spring secured at its upper end within one of the recesses, the lower end of the spring forming an abrupt shoulder.

2. In a window, in combination, a casing having stops, the inner face of one of the stops having recesses decreasing in depth downwardly, a sash slidable between the stops, and a reciprocable bolt carried by the sash and adapted to project into the recesses, and a downwardly facing spring supported shoulder secured within one of the recesses.
