PATENT CHARLES E. TEFFT, OF PAWTUOKET, RHODE ISLAND.
BLIND-*FASTENER SPECIFICATION forming part of Letters Patent No. 678,322, dated July 9, 1901. Application filed November 30, 1900. Serial No. 38,257. (No model.)
My invention eonsistsin the improved com bination of an engaging knob upon the blind with the spring clasping-jaws of a keeper, as hereinafter fully set forth.
In the accompanying drawings, Figure 1 represents a detail elevation showing a portion of a Window and a blind provided with my improved blind-fastener. Fig. 2 represents a horizontal section taken in the line 2 2 of Fig. 1. Fig. 3 represents an enlarged top View of the screw-threaded bolt attached to the blind. Fig. 4: represents a side View of the-same. Fig. 5 represents an enlarged top view of the clasping-keeper adapted for attachment to the window-sill. Fig. 6 represents a side view of the same. Fig. 7 represents a top view of the clasping-keeper for attachment to the side of the building at the back of the blind. Fig. 8 represents an edge view of the same.
In the drawings, Arepresent-s the window,
and B a window-blind provided with a cylindrical perforation, into which is screwed the screw-threaded bolt 0, provided at its opposite ends with the engaging knobs D D, which may be made of any desirable form to fit within the opposite spring-jaws of their respective keepers E E. The keeper E for the window-sill F is preferably made of wire, bent as shown in Figs. 5 and 6 to form the opposite spring-jaws a a and the twisted attaching-shank b, and the keeper E for the side of the building is preferably made of wire bent as shown in Figs. 7 and 8. When the blind B is brought forward to close the same, the knobD will pass between the springjaws at a of the keeper E and be clasped and frictionally held thereby, and when the blind is thrown open the knob D will engage with the spring-jaws of the keeper E to hold the blind in its opened position. The twisted shank b of the keeper forms a screw-thread adapted for holding attachment.
I claim as my invention- In a blind-fastener the combination of the screw-threaded bolt provided with the engaging knobs, with the keepers provided with the spring clasping-jaws adapted for the engagement of the knobs, substantially as described.
