SPECIFICATION forming part of Letters Patent No. 448,498, dated March 17, 1891.

Application filed August 28, 1890. Serial No. 362,874. (No model.)

To aZZ whom it may concern:

Be it known that I, J OSEPH M. BROI-IARD, a citizen of the United States, residing at Clarksburg, in the county of Harrison and State of est Virginia, have invented new and useful Improvements in Sash-Fasteners, of which the following is a specification.

My invention relates to that class of fasteners employed for looking a movable window-sash and holding the same either in a closed position or at any point to which it may be adjusted.

It is the purpose of my said invention to 7 provide a novel and simple device of this charaeteigwherebythe sash maybe securely locked at any point within the jamb or frame without requiring the use of springs or the formation of interlocking apertures in the jamb within which the locking member of the fastener must enter, whereby the sash can only be secured at certain specified points.

The invention consists, to these ends, in the several novel features of construction and new combinations of parts, hereinafter fully set forth, and then definitely pointed out in the claims following this specification.

To enable others to understand and use my said invention, I will proceed to describe the samein detail, reference being had to the drawings accompanying this application, in which- Figure 1 is asectional view of a window jamb or casing, showing the construction and application of the fastener, the latter being shown partly in section. Fig. 2 is a similar view showing the parts in the position they occupy when locked. Fig. 3 is a detail view showing the parts of the fastener separated from the sash and from one another.

In the said drawings, the referencenumeral 1 denotes the casing or jamb of an ordinary window, and the numeral 2 designates the sash or the movable member thereof, which rises and falls within the casing in the usual manner. Within the vertical bar of the sash is formed a recess or chamber, within which is inserted the fastener consisting of two similar semi-cylindrical metallic bars 3 and 4:, fitting in said recesses in such manner as to hold their faces in contact and at the same time permit the free movement of one of said bars in the direction of its length. Upon the outer end of the bar 3 is formed or mounted a flat plate 5, lying in a shallow recess in the sash, whereby its surface is substantially flush with the outer face of said sash, to which it is fastened by one or more screws 6. Upon the outer end of the bar t is mounted a similar flat plate 7, also lying in a recess in the edge of the sash and flush therewith like the plate 5, but wholly disconnected from the frame. Upon the inner end of the bar 3 is pivotally mounted a cam-lever 8, which lies against the flat face of the said bar and is supported by a pivot 9, set therein and formed thereon. This cam-lever is formed of a flat plate of metal of suitable thickness and lies in a recess between the two half-round bars 3 and 4, formed by cutting away the rear end of the bar 4:, thereby forming a shoulder 10, against which the edge of the cam impinges. The inner ends of these two bars 3 and 4 project through the inner face of the sash-bar, thus exposing the lever to view and permitting it to be operated by means of a handle or prolongation 12. By throwing the lever away from the sash the edge of the cam is driven against the shoulder 10 of the bar 4, thereby forcing said bar outward and pressing the flat plate 7 against the jamb or casing with such force as to hold the window firmly at any point by the frictional contact alone. be restored to its normal position and the locking-plate 7 will be withdrawn and returned to the recess in the sash by the contact with the jamb alone, there being no obstacle or resistance to its movement the moment the lever is thrown downward.

This form of lock is simple, certain in operation, and of comparatively inexpensive construction and application.

Rectilinear movement of the bar a is insured by forming a rib 13 upon one part of the duplex. sash-locking device and a groove or channel 14.- in the other adapted to receive said rib. These engaging parts may, if de sired, be dovetailed; but I prefer to make them as shown in the drawings, that being the simplest and least expensive form.

What I'claim is- 1. In a sash-fastener, the combination of Upon releasing the lever the bar will Lil two substantially similar bars to be inserted in a recess or bore in the sash and onehaving means to firmly connect it with the sash, and a cam-lever pivoted upon one of the bars and having its edge constructed to bear against an abutment or shoulder on the other bar for projecting the latteragainst the Win clow-jmnb, substantially as described.

2. In EL sash-fastener, the combination of' two substantially similar bars to be inserted in a recess or bore in the sash and one having means to firmly connect it With the sash, and a cam-lever pivoted upon one of the bars and having its edge constructed to bear against anabutment or shoulder on the other bar for projecting the latter against the windoW-jzunb, one of said bars formed with a rib and the other with a groove, for operation substantially as described.

In testimony whereof I have affixed my 7 signaturein presence of two Witnesses.

JOSEPH M. BROHARD.
