ALEXANDER W. STEELE, OF SALT LAKE CITY, UTAH.
WINDOW-SASH LOCK.
Specification of Letters Patent.
Patented Aug. 1 1, 1908.
Application filed April 16, 1908. Serial No. 427,501.
To all whom it may concern: r
Be it known that I, ALEX ANDER W. STEELE, a citizen of the, United States, residing at Salt Lake City, in the county of Salt Lake, State of Utah, have invented certain new and useful Improvements in Window-Sash Locks, of which the following is a description, reference being had to the accompanying drawing, and to the letters and figures of'reference marked thereon.
My invention relates to improvements in window fastening devices, by means of which a window may be secured in either a fully or partially closed condition, the extent of opening being controllable within the limits for which provision is made.
The primary object of the invention is to provide a simple, durable and comparatively inexpensive window lock of novel construction, which will serve to securely look a window to prevent the entrance of unauthorized persons, while permitting the same to be locked also in partially open position for ventilating purposes.
The fastener is so constructed that it may be readily and quickly attached to any window, without cutting or defacing either sash, the only tool necessary to be used in applying it being a small screw driver, and the device may, therefore, be used without damage and readily removed.
With these and other objects in view, therefore, the-invention consists in the matters hereinafter described and referred to in the appended claims.
The invention is illustrated in the accompanying drawings, in which,
Figure 1 is a side elevation of a portion of a window, to which the invention is applied Fig. 2 is a front view of the fastening device; Fig. 3 is a detail view of the upper sash plate Fig. 4 is a detail ofone of the pivoted boltholding plates; Fig. 5 is a top plan view of the appliances used on the lower sash; and Fig. 6 is a sectional side view of the fastening device.
In these drawings, A represents the window casing, B the lower sash and O the upper sash.
D represents the locking plate having countersunk screw holes, secured to the up per sash, and thin enough so that the lower sash may be raised past it. It is slotted, as shown at a, and has cut out notches b, b,==at top and bottom, these being locking notches when the window is in raised and lowered position respectively. The central or intermediate notch c, may be cut at any point intermediate the top and bottom, this notch being round and large enough to allow the head of the bolt E, hereinafter referred to, to be withdrawn. This is used when it is desired to unlock and open the window to its full extent. There may, of course, be provided as many locking notches b, b, as desired. The plate D is so constructed as to permit the bolt head to slide in the slot a, and also laterally in the notches, while the under surface of the plate is in close contact with the window sash.
Upon the upper frame of the lower sash is attached a metal plate F, of very thin material and secured to the sash by screws or pins (Z, which serve also to hold in position and permit sliding lateral movement thereon of the metal plate G, formed integral with the block H, which supports the sliding bolt E, headed at one end to move in the slot a and notches b, 6, without withdrawal therefrom and at its outer end having a thumb nut 6. Two finger plates or arms f, f, are pivoted to the block as shown at i by pivot pins 1c. fitting openings in said block (see Fig. 6). These finger plates have openings 9 through which the bolt E passes and nor mally the edges of said openings, by pressure of spring h, against the plates, are caused to bind a ainst the bolt and hold it from longitudinad displacement. In order to release the bolt to allow its movement longitudinally, the plates f, f, are swung toward each other, and the bolt may then be withdrawn by the operator. The bolt being threaded on one end and provided with a thumb nut, can be adjusted to various sizes of windows, and this adjustment can also be made use of to bind the sashes together to prevent rattling.
The operation of the device will be readily understood, and its advantages from a practical standpoint readily appreciated by any one. When the parts are in position shown in Figs. 1 and 2, the head of the bolt, by moving the block to the left, so that said bolt head is in lower notch 11, securely locks the lower sash against vertical movement. To raise the lower sash, the block is moved so the head of the boltwill pass out of the notch into the slot (1, and the sash can then be raised to a position where the bolt can be moved to engage another notch b, and the lower sash held in that position. sired to withdraw the bolt, so the lower sash "can be raised to its full extent, the bolt is moved into the round large notch c, and the head can then be withdrawn, the bolt being released by pressing the finger plates f, f, toward each other, thus allowing the bolt to be slid out of the block.
Having thus described my invention, what I claim and desire to secure by Letters Patent, is
1. A window sash lock, comprising a slotted plate, a headed bolt ada ted to move in said slot, locking notches eading oli said slot, and a laterally sliding block carrying said bolt, whereby the latter may be moved into engagement with said notches.
2. A window sash lock, comprising a slotted plate, a headed bolt ada )ted to move in said slot, locking notches eading off said slot, and a laterally sliding block, carrying said bolt, whereby the latter may be moved into engagement with said notches, a notch through which the head of the bolt may be If it is deremoved, and means for releasing the bolt to allow its longitudinal movement.
3. A window sash lock, comprising a slotted plate fixed to the upper sash, a headed bolt adapted to move therein, means for supporting said bolt comprising a block having a lateral movement, and pivoted plates on said block having perforations through which the bolt passes, the walls of saidperforations embracing the bolt.
4. A window sash lock, comprising a slotted plate, with locking notches therein, a laterally sliding block, and a bolt carried on said block adapted to run in the slot of said plate and to engage the locking notches when the block is moved laterally, means for clamping and releasing said bolt to allow it to be moved longitudinally.
In testimony whereof I afliX my signature, in presence of two witnesses.
ALEXANDER W. STEELE.
