UNITED STATES PATENT OFFICE.
JOHN B. CORNELL ANI.) WM. XV. CORNELL, OF NEW YORK, N. Y.
ROLLING SHUTTER.
Specification of Letters Patent No. 28,259, dated May 15, 1860.
To all 'whom it may concern:
Be it known that we, JOHN B. CORNELL and VVILLIAu W. CORNELL, of the city, county, and State of New York, have invented a new and Improved Rolling Metallic Shutter; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings which form a part of this specification.
Figure 1, being a front view of our improved shutter; Fig. 2, a rear View of the same, and Fig. 3, a section in the line of Fig. 2.
ufactured in accordance with the directions in the aforesaid patent of John B. Cornell, have been found to be faulty in the follow ing particulars, viz
First. Unless the sheet-metal slats employed in the manufacture of said shutters are otherwise unnecessarily thick and heavy, the rivets which combine the said slats with the hinge-plates, are liable to have their heads drawn through the slats; and if the rivet heads are not drawn through the slats by the careless handling of the shutters before they are put up, they can afterward be easily driven inward through the same by a punch and malletin the hands of a burglar.
Second. Unless the hinge-plates of the aforesaid shutter are placed at very short intervals from each other, a large opening can be easily made through the shutter either by slitting one of the slats thereof by a properly tempered cutting instrument, or by prying apart the edges of a pair of slats, and then widening the opening thus made by bending outwards the slats each side of said opening.
Third. In rolling up the aforesaid (John B. Cornell) shutter, the contact of the sides of the slats thereof against each other soon wears the paint from them and greatly mars the appearance of the shutter, while at the same time portions of the surfaces of the slats of said shutter are exposed to oxydation.
Now all the aforesaid John B. Cornell rolling completely remedied by stamped metal bosses c, c, at frequent intervals to the face of each of the slats of our improved shutter.
First. The portion of the aforesaid bosses which are placed opposite to the hingeplates of our improved shutter, are firmly secured in their positions upon the faces of the slats thereof by means of the outward extension into said bosses of the rivets which unite the slats to the hinge-plates; the said bosses forming broad bearing heads for the said rivets upon the slats, and the outer ends of the rivets being countersunk into the bosses, the position of the rivets is entirely concealed by an ordinary coating of paint upon the bosses.
Second. Each boss upon our improved shutter has an overreaching curved projection which is of such a shape that when the boss is riveted in its proper position upon a slat, the said projection will pass over and embrace the overlapping sectorshaped portion of the adjoining slat, as shown in Fig. 2; and consequently it will be perceived that while the bosses upon our improved shutter serve the purpose of preventing the longitudinal slitting of the slats thereof, they also serve the purpose of preventing the overlapping curved edges of the series of slats from being pried outward from the innermost curved edges of said slats.
Third. In rolling up our improved shutter, the bosses upon the face thereof will be brought in contact with each other, and consequently the face of the slats will be protected from the possibility of defacement or injury during said process. And furthermore, by giving an ornamental shape to the bosses upon our improved shutter, it will greatly surpass all other rolling metallic shutters in artistic elegance of appearance.
What we claim as our invention and desire to secure by Letters Patent, is-
1. Preventing the longitudinal slitting of the individual slats of a rolling metallic objections to the shutter, we have riveting cast or shutter by combining a series of bosses With ing forcibly separated from each other subthe face of said shutter substantially as herestantially as herein set forth.
in set forth. JOHN B. CORNELL.
2. We also claim giving the metallic bosses WILLIAM W. CORNELL. 5 upon the face of our improved rolling shut- Witnesses: Y
ter such a shape that they Will prevent the ADDISON A. SAYRE, edges of the slats of said shutter from be- IRA L. CARBY.
