Description

J. GREY ',JEWELL, OF WASHINGTON, DISTRICT COLUMBIA.

Letters Patent No. 70,222, dated October 29, 1867.

IMPROVED WINDOW-SASH STOP.

T0 ALL WHOM IT MAY CONCERN:

Be it lmown that I, JAMES GREYJEWELL, ofthe city and county of Washington, and District of Columbia., have invented` a new and improved Mode of asteningWindowSa-sh; and I do hereby declare that the following isa full and exact description of the same, reference being had to the accompanying drawings, and to letters of reference markedthereon. i v

The nature of my invention consists in providing a screw-bolt, with square nut and cap or handle complete, to be made of' iron, brass, steel, copper, or other metal or composition, which is to be inserted in or on the side of a window-sash, at'the point most desirable, and of the required length. This insertion is made by boring a gimlet-hole through the sash, from exterior to interior, at the side; then cutting a small mortise through the centre of the sash, midway of the aperture made by the gimlet; then place the nut in'the mortise square and tight, covering the same with a small piece of wood firmly; then pass the screw-bolt through the nut, until the head or face of the s`crew-boltcomes blui` with the face of the sash; then screw on the cap or handle, tight, or attach the screw-head or pad, (Figures 5 and 6.)` When it is desired to fasten the window at any' height or lower it to any angle, raise or lower the sash, and turn the screw until it presses hard against the window-frame and is compact and tight. The sash is then locked, and cannot be raised or lowered unless the fastener is unscrewed. This invention is not only applicable to window-sash, but may beI applied to any desirable sliding panel.

The following will be found to be a correct index to the drawings:

A is the screw with enlarged'head, to press against the window-frame, made either solid, or hollowed out und filled with rubber or suitable substance for preventing the abrasion of the window-frame.

B is the screw-cap or handle, by turning which the screw-head is forced against the window-frame. This head or cap is secured to the screw A by another screw, a.

O is the square nut through which .the screw A passes, and which resists the pressure of the screw-head against the window-frame, thereby forcing the sash over, and securing ,it tightly in any position.

Figure 2. D is the metal plate for attaching to car windows, or where the sash is too thin to allow .mortising for the use of a, iig. 1, to be made with Ltwo or four ilanges or wings, as may bedesired.

`Figure 3. E is the domestic windowsash.

Figurefl. E is the railway-car sash, with thefastener, as applied.

Figure 3. F is the domestic sash, with the fastener attached, showing the mortise for the scat of the nut, a gimlet-hole being bored from the exterior to the interior of the sash, to admit the screw through the'nut.

Figures 1 and 2; a is the screw securing the cap, handle, or button B to the screw A.

I claim the screw-head or pad A, made hollow, and lled with gutta perche., rubber, leather, composition, cork, or other substance that may be used for preventing the abrasion of Vthe window-frame.

I claim theibutton or handle, made in one piece with the main screw, and attached to a screw-head or pad by a swivel or shoulder-joint, with a small screw penetrating the screw-head or pad, as and for the purpose set forth.
