sAsH-FASTENER.

SPECIFICATION forming part of Letters Patent N0, 266,799, dated October 31, 1882.

Application filed September 11, iSSQ.

To all whom it may concern:

Be it known that I, LoUIs FELsBURG, ot New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Sash -Fasteners5 and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a side view; Fig. 2, a top view with the covering removed; Fig. 3, a transverse section through the locking-lever; Fig. 4, the fastener as applied to use.

rIhis invention relates to an improvement in that class of sash-fasteners which are designed to be arranged upon the top of the upper bar 0f the lower sash, with. a locking mechanism which will engage both the upper sash and the jamb, whereby not only will the two sashes be locked together, but also locked to the jamb, and in any desired relative position, as open or closed, andso that disconnecting one sash from the other also disconnects the locking mechanism from thejamb; and the invention consists in the details of construction of the fastener, as hereinafter described, and more particularly recited in the claim.

A represents the case, which is of rectangular or any suitable form, and constructed to be attached to the top bar, B, of the lower sash,as seen in Fig. 4. Longitudinally through the case is the bolt C, which projects outward through the jamb end to form the nose a, and at the other end is provided with a suitable handle, D, by which itmay be moved. A spring, E, inside the case on the boit, serves to force it forward into its locking position, and so that in drawing the bolt, as seen in broken lilies, Fig. 2, the spring will be compressed.

F is a transverse belt, its nose b projecting' throughI the case on the back side, and so as to enter the upper sash, Gr, as seen in Fig. 4.

rlhe principal bolt C is constructed with a diagonal rib, d, which works in a corresponding diagonal groove in the bolt F. rlhe bolt F is free for movement in the direction of its axisthat is7 at right angles to the principal bolt. Hence, as the principal bolt is moved in one direction or the other it will, because of (No model.)

the inclined rib d working' into the transverse bolt, impart a movement to that bolt F at right angles to the axis ot' the bolt C to the extent of the inclination of the rib d. The normal condition ot' the nose of the bolt F is thrown out, as seen in Fig. 2. The drawing of the bolt C also draws the bolt F inward, as seen` in broken lines, Fig. 2.

' rlhe mechanism is inclosed within the case in the usual'nianner for securing like mechanism in other classes oflocks. It is secured upon the top of the lower sash by means of screws or otherwise, and a hole is lnade in the jamb corresponding tothe nose a ot' the bolt C, and a similar hole into the stile ofthe upper sash, G, corresponding to the end b of the bolt F, as seen in Fig. 4, and so that the spring ofthe bolt, when the parts are in their proper relation to each other, will throw the two bolts respectively into the jamb and into the upper sash, which will not only lock the two parts together by means of the nose of the bolt F, but` will also lock the two to thejamb by means of the nose a of the bolt C. The jamb may have several holes in the path of the bolt as the lower sash is raised, and `the stile of the upper sash may also have several holes in the path of the transverse bolt, so that the lower' sash may be raised to any desired position and there engage the jamb and upper sash; or the upper sash may be lowered to any desired point and engaged by its bolt, or the lower sash may be raised and the sash dropped to a certain extent and there engaged.

In order to loch the bolt to prevent the possibiliry of tampering with it from the outside, I arrange a locking-lever, H, in the case, pivoted at one end, as at c, the other end provided with a stud extending through a slot in the case, and there furnished with a suitable handle, L, by which the lever may be turned upon its pivot, as seen in broken lines, Fig. 2. The lever is provided with a finger, 7L, which engages a corresponding notch in the bolt. A spring, I, serves to press the lever toward the bolt and into engagement therewith. Then it is desired to unlock the bolt the linger h is withdrawn by turning the lever H, as indicated in broken lines, Fig. 2. In that condition the bolt is free for movement in either direction, and is locked when the bolts are thrown into IOO engagement with thejamband sash. A noteh in the bolt may also be provided, with which the finger h will engage when the bolts are drawn, so as to `hold the bolts in their withdrawn condition and leave both sashes free to be moved.

I have described my fastener as applied so that the principal bolt enters the jamb and the transverse bolt the sash. It Will be evident,however,tl1atthisordermay be reversedas, for illustration, the fastener in Fig. 4 may be plaeedat the opposite side of tbe lower sash. Then the nose b would enter the jamb and the nose a will enter the stile of the upper sash.

From the foregoing it will be understood that I do not claim broadly a saslrfastener attached to the lower sash and provided with spending transverse movement to the bolt F 3o and the locking lever H, substantially as described.
