WILLIAM 2A. SUBLTT, OF SAN FRANCISCO, CALIFORNIA.
Letters Patent No. 85,973, dated January 19, 1869.
IMPROVEMENT IN -SASH-LOCKS.
To all whom it mar/y conce/rn:
and accompanying drawings are sufficient to enable any person skilled in the art or science to which it most nearly appertains, to make and use my said invention or improvements without further invention or expeiil ment.
The object of my invention is to provide an improved device for supporting the sash of windows at any desired elevation, in such a manner as to preclude all possibility of their falling, unless it is desired to lower them by operating the device.
IMy invention also relates t0 a mode of securing the windows when closed, so that they cannot be opened from the outside; and
It consists in forming, in the casing, opposite the sash, an opening, deepest at the upper end`,`and tapering to the bottom, forming an incline slot, in which a round metal ball is placed, which, falling to the lower part of the slot, binds the sash tightly, and prevents its falling.
A lever, with a projecting handle, is so arranged that, by pressing down upon it, the ball is raised to a wider part of the slot, and the window is allowed to fall.
A small catch is pivoted above the handle of the lever, which may be turned down, and 4thus lock the sash,l so that it cannot be raised until the catch is freed.
To more fully illustrate and describe my invention, reference is had to the accompanying drawings, and letters marked thereon, Vof which- Figure 1 is a front elevation of a window, with the front casing of the frame removed; and
Figure. 2, a sectional elevation of the frame, as seen edgewise.
Figures 3 and 4 show the locking' apparatus on a large scale. v
A ,is the casing of a window-frame, up and down which the window-sasl1 B slides.
Inl order to give a durable face'for the ballG to work on, I form a metal plate, D, with a chamber, E, at one end. I
This chamber is larger near its topthan at the bottom.
'Ihe plate D is let into the casing, and so placed `that the inclined depression or chamber E will be hid by the sash when it is inplace.
A lever, F, having one end operating up and down in the chamber E, is attached, by means of a screw, a, to near the centre ofthe plate, which is counters'unk, so as to receive it, and give it room to be moved 11p and down. l v
A second plate, G, is then placed over the i501), and conned by the screw a, which also passes through it.
The plate Gr is provided with openings at each end,
one, H, being directly -over the chamber E, and made,
circular at the top, and larger than at any other part, in order to admit the ball into the chamber, while the opening I, at the opposite end, is made circular in form, and through which the handle bprojects, andmoves the lever up and down, describing, in its movement, the arc of a circle.
The whole is then secured to the casingiby screws,
the plate G being flush with the face of the casing.
The ball O is then placed inside the Ychamber by passing it in at the circular top, whenk it will fall until it is caught by the side of the incline chamber and sides of the opening, in which position a portion of the ball will protrude from between them.
Thewindow-sash being placed in position, it is al lowed to rise, as desired, the ball receding to a deeper portion of the chamber, but, the instant the upward pressure is discontinued, the ball willdrop down, and bind between the sash and incline, and prevent its further lowering, when, by simply pushing down onI the handle l1, the point of the lever, which is under the ball, will raise it, and allow the window to descend.
In order to prevent the ball from indenting and l ber, causing it to bind above instead of below, thus` securelyfastening down the sash.
-The upper sash need not be supplied with this hook, as Ythe ball always keeps it up, and it is necessary to operate the lever to lower it.
By thus constructing window-supporters and fasteners, the danger of the sash falling is avoided, the window can be raised as much or little as desired, when it immediately binds, while the cost of applying it to the frame is very small.
Having thus described my invention,
What I claini, and desire to secure by Letters Pate ent, is-
In combination with the detached ball G and lever F, the slot E,narrowed-both at top and bottom, and the catch P, for holding the ball against the upper inclne in the lower sash, to fasten'it down, substantially as described.
In witness whereof, I have hereunto set my hand and seal.
