Description

UNITED STATES PATENT OFFICE.
THOMAS M. WORCESTER, OF CINCINNATI, OHIO.
IMPROVEMENT IN ADJUSTABLE WINDOW-SCREENS.
Specification forming part of Letters Patent No. 129,200, dated July 16, 1872.
Specification of an Improved Adjustable Window-Screen, invented by THOMAS M. WORCESTER, of Cincinnati, Hamilton county, Ohio.
Nature and Objects of the Invention.
This is an improved form of those screens which consist of a pair of open rectangular frames filled with wire-gauze, said frames being made capable of being slid out or in upon each other so as to fit andfill any width of window.
- "GenemFDescript'ion.
Figure 1 is a perspective view of an adjustable screen, embodying my invention. Fig. 2 is a section in the line :0 w. Fig. 3is a section in the line 3 3 showing the panels separated. Fig. 4 is a perspective view of one corner of a panel. Fig. 5 is an enlarged transverse section through two horizontal rails of the panels.
A and A represent two precisely-similar rectangular frames or panels, open in the middle, and having said open middle covered with sheets of wire-gauze B B. So far as described my apparatus does not differ materially from others of its class.
The feature of my improvement consists wholly in the devices for holding to each other the two frames with capacity for mutual adjustment by sliding one upon the other, so as to fit any particular window. These devices are as follows: The frame A has projecting from its rear side, near its left hand end, two T-formed tongues or tenons, of which the tenon O is in the upper and tenon G in the lower bar or position of the frame. Similarly the frame A has two tenons, C 0',- projecting from its front right-hand portion.
There are provided in the contiguous face of each frame two under-cut grooves, D D and D D, having open ends (1 d d d, which in the closed condition of the frames, permit the insertion of the said tenons into .their proper grooves, when, the frames being drawn slightly out, the parts remain securely retained to each other, and in such a manner as to effectually exclude insects, when placed between the sill and the lower sash of a window.
These tenons may be secured to their proper panels in any convenient way. That adopted by me, and which proves to be cheap and effectual, is to form the catch-tenons with a spreading base, 0, which,.being inserted in the open end (I of the groove in said panel, is pushed to the further end of said groove and permanently secured thereto by a pin or a screw.
This arrangement is simple, strong, and effectual, and permits the utilization of almost the entire width of both screens for a wide window.
, Claim.
I claim the pair of sliding screens having the tenons G O O 0', and grooves D d D d D d D d in their contiguous sides, as and for the purpose set forth.
In testimony of which invention I hereunto set my hand.
THOS. M. WORCESTER.
