JNO. L. BASSETT, OF BRIDGEPORT, CONNEC'IIGU'I.4

WIDOW-BLIND FASTENER.

Specification of Letters Patent No. 5,305-, dated September 2,5, 1847.

To all 'wh-0m t may concern Be it known that I, JOHN L. BASSETT, of Bridgeport, in the county of Fairfield and State of Connecticut, have invented a new and useful Improvement on Window-Blind Shutters and Door-Fastenings; and do here-y by declare thatV the following is a full, clear, and exact description of the construction andV operation of the same, reference being had to the annexed drawings, making a part of this specification, in which.d t

Figure 1, 1s a perspective view of the latch piece disconnected from the plate and spring. Fig. 2 is also a perspective view ofv the latch piece plate and spring connected, the latch piece having been slipped into the mortise of the plate and the spring put around the prong. Fig. 4 represents the fastening turned upside down. Fig. 6 repsesents the blind fastening plate.` Fig. 3`

represents the spiral spring.

The nature of my improvement consists in providing a latch for a blind or shutter or door fastening with certain parts which connect it to the plate. One ofsaid parts is set 0H on the edge or side of the latch which I name a shoulder F. This sets on the plate. Another 2d one of these parts is a projecting branch A, setting out some distance onthe other edge of the latch and rests on the plate. Another 3d one of said parts is a narrow strip. I name it prong B, which is plate is D, the point ranging with the edge of the plate. I call it notch. The center of the notch D sets against the edge of first mentioned makes one'side ofsaid notch.

Theother side of the notch is made 'by a jut called E.

To enable others skilledin the art to make lthe plate. They under part of they shoulder and use my improvement, I will proceed to describe its construction and operation. *n

I construct my appendages to hold back against and to the building in any of the known forms; also the hook part on the ends of the latch pattern are shaped like any of' the known forms. VButpin orderto obviate the expense and labor` arising from boring vout from the plate by riveting on the sides of the mortise projecting pieces for holding a pivot for t-he latch to swing on, I make a notch in the edge of the latch piece so that it rests immediately on the plate as shown at l F in the accompanying drawing.

I in general cast the latch piece of brass 'or iron, first having made a correct pattern.

I construct a sufficient number in imitation of it and arrange them on a plate of metal'or a board in rows in a manner most convenient for molding. They maybe cast'out of any of themetals generally used for such articles or if more convenient they may be stamped out with a die and plate.

What I claim as my improvement and desire to secure by Letters Patent is- Connecting the latch to the plate by the notch D and projecting branch A in combination with the prong B and spring 3;

Witness my' hand this fteenth day of` September 1847.
