UNITED STATES PATENT QFFICE.
JOSEPH F. GRAHAM, OF WARRENSBURG, MISSOURI, ASSIGNOR OF ONE- HALF HIS RIGHT TO ALEXANDER BETTES, OFSAME PLACE.
IMPROVEMENT IN SASH-HOLDERS.
Specification forming part of Letters Patent No. 138,494, dated May 6, 1873; application filed September 4, 1 872.
To all whom it may concern:
Be it known that I, JOSEPH F. GRAHAM, 0t Warrensburg, in the county of Johnson and State of Missouri, have invented certain new andusefullmprovements in Window-Sash Supporters; and I do hereby declare that the follo win g is a full, clear, and exact description there of, that will enable others skilled in the art to which it appertains to make and use the same, reference bein ghad t0 the accompanying draw ing and to the letters of reference marked thereon which form a part of this specification'.
In the drawing, Figure 1 presents a view, in section and elevation, of the device attached to a window-frame, in which A is the upper sash; B, the lower sash, to which the device is attached; 0, the windowcasing. D is the screw, which forms the principle upon which the securer acts. This screw D is operated by means of a movable handle or wrench, E, attached to it by means of a rivet, 0. This wrench E is raised up vertical- 1y, without turning on the pivot e, and thus turns the screw D one-half revolution. It is let fall around the pivot e and is raised again, as before, and the operation repeated until the screw D is run through against the metallic strap I*, which is fastened by screws f f at one of its ends; it forces this strap against the window-casing, so that, without injuring the surface of the latter with the end of the screw, the friction can be made great enough to securely fasten and secure the window at any point.
The screw D may operate in a thread worked into the wood of the sash directly; or it may pass through a metal plate sunk flush with the sash next to the window-casin g, as shown at G.
This sash-supporter presents such a combination of appliances as would render it proof against picking, as it lies so close to the glass that the screw cannot be turned. without these successive operations with the lever or wrench August, 1872.
JOSEPH F. GRAHAM.
