WILLIAM E. BROCK, OF NEW YORK, N. Y.
IMPROVEMENT IN METAL SLATS FOR SHUTTER-BLINDS.
Specication forming part of Letters 4Patent No. 122,806, dated January 16, 1872.
To all whom it may concern:
Be it known that I, WILLIAM E. BROCK, of the city, county, and State of New York, have inventedva new and Improved Metal Slat for Shutter-Blinds; and I do hereby declare that the following is a full, clear, and exact descrip tion thereof, reference being had to the accolnpanying drawing forming a part of this specilication.
This invention consists in a novel manner of securin g the rod, whose ends form the tenons or pivots, to the slat, whereby greater strength is given the slat, and the rod is more rmly secured thereto.
In the accompanying drawing, Figure l is a face view of a portion of a slat made according to my invention, and Fig. 2 is a transverse section of the same.
Similar letters of reference indicate corresponding parts in both figures.
Formed longitudinally in the slat is a central,
groove-like bend, b, which is of a size to it a rod, B, whose ends form the pivots of the slat, and of a depth to encircle about two-thirds of the circumference of the said rod. At suitableintervals throughoutthe length of this bend the so-bent portion of the plate is slit or cut across, as shown at wa in Fig. 1, and alternate portions bounded by these slits are bent back in a reverse direction through the groove b to form bearings for the other side of the rod; and as the groove b, as has before been described, is of such size as to encircle twothirds of the circumference of the rod, if the portion between the slits a a were all bent back it would be more than sufficient to encircle the uncovered third; consequently, the
surplus metal is doubled over to form rib-like projectn g folds e e above and below the center of the rod, thereby giving additional strength to the slat, and very firmly securing the pivotrod B thereto by stiliening the connections of the loop-like portions e e with the body of the slat.
What I claim as my invention, and desire to secure by Letters Patent, is-
The slat formed with a groove-like bend, b, reversed bends c e, and projecting folds e c, and receiving the pivot-rod B, substantially as and for the purpose herein described.
W. E. BROCK.
