SASH-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 424,454, dated April 1, 1890.

Application filed January 24, 1890; Serial No. 337,912- (No model.)

To ctZZ whom it may concern:

Be it known that I, JAMES S. BIERY, a citizen of the United States, residing at Allentown, in the county of Lehigh and State of Pennsylvania, have invented certain new and useful Improvements in Sash-Fasteners; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i

This invention relates to saslrfasteners, and is intended more particularly to fasten the two sashes of a window against lateral movement in the window-frame, as when the wind is high, although it may also be used to lock the said sashes when desired.

The invention consists, broadly speaking, of a casing seated in the edge of the sash, a catch pivoted in said casing on a vertical pivot and having a serrated tip adapted to engage the head in the window-frame, and a thumb-screw for throwing said catch into operative position, with a spring for retracting it.

The invention also consists in certain details of construction and arrangement of parts for carrying out this general idea, all as more fully described in this specification and illustrated in the accompanying drawings, forming a part thereof, and in whieh Figure 1 is an inside View of a window with the upper and lower sash-fasteners applied thereto. Fig. 2 is a. perspective View of the beads on the windowsash, showing the trans- Versely grooved or serrated strips applied thereto. Fig. 3 is a plan, and Fig. 4 a horizontal section,of the catch used on the upper sash. Fig.5 is a plan, and Fig. 6 a horizontal sectional view, of the catch used on the lower sash; and Fig. 7 is a perspective detail of the thumb-screw and slotted plate and nut used in the lowensash catch. Fig. 8 is a perspective view of the modification shown in Fig. 6 without the thumb-screw.

It will be understood that I prefer to use two forms of this improved fastener, one on the upper and the other 011 the lower sash, although that for the upper sash may be used on both sashes if preferred. Although the drawings illustrate but one fastener on each to the entire window. These two forms of fasteners possess certain details common to both, which will now be described.

Referring by letter to the said drawings, 0

designates a casing, preferably of metal, pro-' vided with a transverse recess R in its center and a hole H through its rear face at its outer end. Mounted on a vertical pivot-pin P within this casing is-a catch K, which is shaped like an arc of a circle and at one end has a circumferentially-projeeting tip T with a serrated face, the serrations S therein running horizontally, as shown. The casing O is set into a mortise or recess in the edge of the sash, and is preferably cut away, as .shown at A, so that that portion of the casing which surrounds the hole H, through which the tip projects, shall stand flush with the outer edge of the sash, whereas the remainder of the casing will be embedded within such sash. The outer end of the casing is provided with vertically-extending perforated ears E, which are sunk within shallow recesses in the edge of the sash, and screws are passed through the perforations therein and into the sash above and below the casing, whereby the latter is removably retained in position, all as will be obvious to and clearly understood by an experienced sash-builder or carpenter without more explicit explanation or illustration.

The recess R in the upper sash-fastener is closed at its inner end by a shoulder 4 and the catch K is shaped in the form of a quarter of a circle, its inner end normally abutting against this shoulder and held there by a coiled or other shaped spring G. A threaded opening is bored through the body of the fastener in a horizontal plane parallel with the window-pane when the fastener is in place, and in this opening works the thumbscrew M, whose point when screwed in bears against the rear face of the catch K and turns it on its pivot to throw its tip T outwardly,

all as shown in Figs. 3 and 4. The thumbscrew has a flattened head m, which is of such a size that it can be turned without striking the glass and the catch operated thereby.

The lower sash-fastener has its recess R provided with an enlargement or opening 0 at its inner end, in which a nut N plays horizontally and at right angles to the plane of the glass. The catch K in this instance is in the shape of a semicircle and has a horizontal slot in its face at its rear end, as shown. The thumb-screw M in this instance enters the fastener at about right angles to the glass, passes loosely through said slot, and engages the threaded hole in the nut N. A metallic plate may be provided at the base of the opening 0, against which the end of the thumbscrew bears, whereby when said thumb-screw is turned the nut N is drawn inwardly. The inner end of the catch K is thereby forced inwardlyand the outer end or tip T projected through the hole H in the same manner as above described. A coiled or other shaped spring G is also provided in this instance, which presses the catch into its normal position against the force of the thumb-screw; or a metallic plate or disk D may be provided, having a slot d extending from its center to its periphery and screwed or otherwise fastened to the inner face of the sash, and an annular groove 9 in the body or shank of the thumb-screw engages this slot, whereby when the'thumb-screw is turned the nut N is drawn up in the same manner with the same result; or both the plate and disk D may be used, if desired, in order to give the device greater strength. A plate W, having lateral serrations or notches w, is applied to the inner face of the outer bead in each groove within which the sashes slide, and when the catches K are pressed outwardly the serrations S in their tips T engage with the serrations w in said plates, whereby the sashes are locked against vertical movement, thus rendering the device a sash-lock, although it will be understood that said serrations and plate may be entirely omitted, if preferred, Without defeating the principal aim of the device.

The important end and object of this invention, as will be at once apparent from the above description of its details and their operation, is to prevent lateral movementof the sashes in the grooves in the window-frame. In their normal positions the catches K do not in any way interfere with the raising and lowering of the sashes; but when the tips of said catches are thrown outward by turning the thumb-screws the sashes are pressed inwardly thereby closely against the inner vertical beads of the groovesin which they slide, and all rattling of the sashes is prevented. At the same time the employment of the serrations in the ends of the tips and of the plates upon said beads in no way interferes with such action of the catches or prevention of lateral movement of the sashes, but simply adds the feature of a vertical locking of the sashes and renders the ordinary sash-lock between the central cross-bars of the sashes unnecessary.

Considerable departure may be made from the construction above described without changing the nature and scope of the inven tion, and I therefore do not limit myself tothe details set forth. I prefer, however, to

use the lateral thumb-screw and its casing on the upper sash, in order that the fastening may pass freely by the upper rail of the lower sash, and the transverse thumb-screw on the lower sash or wherever possible, because it extends straight into the room and can be more easily operated by the user. I also prefer to provide the tips with the serrations described and to employ the notched plates in the grooves, because they add but little to the cost of the completed article and considerable to its value, as above set forth.

This improved fastener can be put into the sash when the window is newly made, and as the sash and frame contract by drying and shrinking,and more lateral play between them is thereby created, it will be useful for tightening and fastening the sash until the latter has the unusual play of half an inch, that being preferably the length of the tip. As is well known, the sill of a window-frame slopes outward. The fastener on the lower sash presses it inwardly into the obtuse angle formed by this sill at the lower part of the frame, thus preventing cold air and rain from blowing in under the lower sash. r

In order to accommodate the fastener to sashes of different thicknesses, a longer or shorter thumb-screw may be used or a catch of a greater or less circle.

Having thus described my improved sashfastener, what I claim as the salient. points thereof is-= 1. The herein-described sash-fastener, the same comprising a catch seated in the edge of the window-sash, and means, substantially as described, for moving it transversely to the plane of the window and throwing its tip against the bead in the window frame, as and for the purpose set forth.

2. A sash fastener comprising a casing seated in the edge of the windowsash, a catch mounted on a pivot therein and having a tip, a spring holding said catch in normal position, and means, substantially as described, for turning said catch on its pivot and throwing its tip against the bead in the window-frame, as set forth.

3. A sash fastener comprising a casing seated in the edge of the window-sash and provided with ahorizontal recess, an arcshaped catch loosely mounted in said recess on a vertical pivot and having a tip projecting outwardly through the side of the casing, a spring holding said catch in normal position, and means, substantially as described, for turning said catch on its pivot and throwing said tip against the bead in the windowframe, as set forth.

4.. A sash fastener comprising a casing seated in the edge of the window-sash and provided with a horizontal recess opening inwardly and a hole opening outwardly, an areshaped catch loosely mounted in said recess on a vertical pivot and having a circumferentially-projecting tip adapted to pass through said hole, a spring holding said catch in nor mal position, and a thumb-screw engaging a threaded opening and turning said catch against the force of said spring, as and for the purpose set forth.

5. A sash fastener comprising a casing seated in the edge of the Window-sash and provided with a horizontal recess opening inwardly and a hole opening outwardly, acatch comprising a straight bar loosely mounted in said recess on a vertical pivot through one end and an arc-shaped bar leading from the other end thereof around said pivot and having a tip adapted to pass through said hole, a coiled spring bearing at one end against the interior of the casing and at the other against the front of said straight bar, and a thumbscrew engaging a threaded opening and turning the catch against the force of said spring, as and for thepurpose set forth.

6. In a sash-fastener, the combination, with the casing 0, seated in the edge of the Windowsash, said casing having a horizontal recess R, With a shoulder r at its inner end and an outwardly-opening hole H from the outer end of said recess, of the catch K, having atip T,

adapted to pass through said hole, a spring G, for retaining said catch in normal position,

- and a thumb-screw M, engaging a threaded opening in said casing and bearing upon the rear end of said catch, the whole constructed as and for the purpose set forth.

7. In a sash-fastener, the combination, with the catch K, mounted on a pivot in the sash and having a tip T, provided With horizontal serrations, of a plate WV, secured to the window-frame and provided with horizontal serrations w, and means, substantially as described, for turning said catch on its pivot, asand for the purpose set forth.

8. In a sash-fastener, the combination, With the catch K, mounted on a vertical pivot in the sash and having an extended tip T, passing laterally outward through the side of said sash, the face of the tip being laterally ser rated, of a plate W, secured to the outer bead of the groove in the Window-frame and provided with horizontal serrations w, and means, substantially as described, for turning said catch on its pivot, as and for the purpose set fortha In testimony whereof I aihx my signature in presence of two witnesses.
