IMPROVED SASH-FASTEN ER.

Specification forming part of Letters Patent No. 16,595, dated February 10, 1857.

To @ZZ whom t 71u03/ concern:

Be it known that I,- WV. W. KELLocG, of Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented a new and useful Double-Acting Sash-Fastener; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, mal;- ing a part of this specification, and to the letters and figures of reference marked thereon.

A A is a common window-frame.

B and C are the lower and upper sashes.

I) is the cleat for confining the lower sash.

E is the inner cleat for confining the upper sash.

l 2 3 4t are small holes, round or otherwise, cut through the cleat E, and also into the side of the upper sash C, to the depth of half an inch, more or less. The holes in E and C are of the same size and the same distance apart.

-If desirable, for the sake of greater durability the holes may be fitted with metallic tubes. The holes in E and C may be cut at once after the sash is fastened into the frame.

F is a thin plate of brass or other suitable metal fastened to the top of thelower sash by means of screws.

G is the hasp or bolt, shaped as seen in the gure and either cast or cut out of brass or other suitable metal, one end of which, as seen in the figure, passes through the holes in cleat E into corresponding` holes in the side of the upper sash.

H is a pin passing through G and made fast in the plate F. This pin answers both as an axle for G to turn on and also as a fulcrurn for the wire spring J, which is wound loosely about it. The shorter end of J, as seen, is fast in the plate F, the longer end being continued so as to press against the back side of the upright pin I, which is made fast in G. The effect of this spring J will obviously be always to press the farther end of the hasp G into the holes in E and C.

In order to withdraw the hasp from any ot' the holes, the operator has only to put his thumb or finger on the pin I and press it toward the glass. It will thus be seen that the hasp G, in combination with the holes in E and C, confine at any point and at the same time both the upper sash and lower, Whether they are both entirely closed or partly open, as seen in the figure. It is also obvious that either the upper or lower sash may be raised or lowered at pleasure more or less independently of the other whenever the hasp G is withdrawn from the holes.

I am aware that fasteners have been applied to the top of the lower sash and the bottom of the upper in the middle for confining the two sashes when both are completely shut; but in order to'coniine both sashes simultaneously at any point it is necessary that thetwo should not only be united together, but also at the same time made fast to some part of the window-frame, and this I have done by making the holes in the inner cleat E, as well as in the side of the upper sash C, as described.

What I claim as my invention, and desire to secure by Letters Patent, is-

The use of the hasp G, constructed as described and operating in connection with the perforated cleat E and upper sash C, in the manner and for the purpose set forth.
