WINDOW-LOCK.

Patented Jan. 16, 1906.

Application filed February 2'7, 1905. $eria1 No. 247,464.

To all whom it may concern Be it known that we, ELIAs E'rznNHoUsnR and ROSANNAH L. Monss, citizens of the United States, residing at San Jose, in the county of Santa Clara and State of California, have invented new and useful Improvements in Vindow-Locks, of which the following is a specification.

Our invention relates to a device which is especially designed for locking the sashes of' vertically-slidable windows to each other and also to the casing, so that the sashes may be locked either closed or one or both of them partially opened and rendered immovable while so locked.

The invention consists in the combination and arrangement of parts by which the looking may be effected, and in details of construction which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a perspective view of our locking device, partly in section. Fig. 2 is a side view of same applied to a window. Fig. 3 is a front view of Fig. 2. Fig. 4 is a view of locking-bolt 11.

It is the object of our invention to provide a means for quickly and safely locking window-sashes together and also to the casing.

As shown in the drawings, A and B are two plates, the plate A being fitted to be secured upon the top of the lower sash 2 and near one edge, and the plate B is hinged to the plate A, as shown at 3, so as to extend upon the inside face of the vertical side of the upper sash 4. The plate A has the housing of a bolt 5, which is slidable within the housing, and the point is adapted to engage in openings, as at 6, made in the channel in which the lower sash slides. The bolt may be moved by a knob in the usual manner of such bolts, but it is preferably actuated by a spring 7, inclosed within the housing of the bolt and pressing against the rear end thereof. The point of the bolt is preferably rounded or tapered, as shown, so that as the sash is pushed up the spring will impel 5 ing which may be found desirable.

The plate B is hinged to the plate A, as

shown at 3, the hinge-joint being at such point that the plate B when standing vertically lies flat against the vertical portion of the upper sash. It has a hole made through it to receive a 'turnable locking-bolt.

Upon the side of the sash is fixed a plate 9, having holes made through it at intervals with slots extending transversely of the holes, as shown at 10. The side rail of the upper sash has recesses corresponding to those of the holes in the plate 9.

The locking-bolt consists of a conicallyshaped head 11, having wings or projections 12 upon opposite sides, and these wings or projections and the cone are adapted to slip into either of the openings 10 and the radial slots thereof when the wings are in line with these slots. The bolt being then turned so that the wings stand transversely and not in line with the slots it will be seen that the device is perfectly locked. In order to conveniently turn this locking-bolt, the stem has fixed to its outer end a plate or handle 13, which may have a loop or turned-over portion, knob, or other attachment, as at 14, by which to conveniently operate it.

The channel having the holes with which the bolt 5 engages is also preferably provided with a lining-plate through which the holes are made.

The lower sash having been locked at any desired point, as previously described, it is only necessary to move the upper sash to such point as may be desired by bringing one of the openings 10 into line with the conical bolt 11. Then by turning the handle 13 until the Wings 12 are in line with the radial slots of the opening 10 the bolt may be pushed into the central opening, and, the handle being turned, the wings 12 will pass beneath the plate, the opening below the plate'being of sufficient size for the purpose, and will then stand transversely of the opening and form a perfect look. When both sashes are closed, it will be understood that one of the openings for the bolt 5 will be in line with the bolt, which will be caused to engage with the opening by the action of its spring, and one of the openings 10 will be in line with the tapered or conical bolt 11, which can thus be pushed in and locked by turning its handle. If it is desired to open either or both the sashes, it may be done by disengaging the lock-bolt 11 and tilting the hingeplate B, when the upper sash may be lowered and again engaged with its bolt, and the lower sash may in the same IIO manner be raised and engaged with the easing, so that a sufficient ventilating-opening may be had both above and below the sashes and the two will be so looked that they cannot be further moved.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

A sash-fastener having in combination two flat plates hinged together along their meeting edges one of said plates adapted to be fixedly secured on the top rail of the lower sash and having a housing which extends parallel with the hinge of said plates said housing having a closed rear end and a longitudinally- I extending slot offset at the front end, a spring in the rear portion of the housing, a bolt slidable in the housing and normally projected by the spring, said bolt having a knob operable in the slot of the housing, a turnable bolt mounted in the other plate said bolt having a conically-shaped head and lateral Wings or projections, and a handle-piece by which the bolt is turnable, a plate adapted to be secured to the upper sash having keyhole-slots engageable by the head and wings of the turnable bolt, and a plate adapted to be secured to the window-casing having openings engageable by the spring-actuated locking-bolt.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
