JAMES G. WILSON, OF NEW YORK, N. Y.
IMPROVEMENT IN ROLLING SHUTTERS.
Specification forming part of Letters Patent No. 155,398, dated September 29, 1874; application filed August 26, 1874.
To all whom it may concern:
Be it known that I, JAMES GODFREY WIL- SON, of the city, county, and State of New York, have invented a certain new and useful Improvement in Rolling Shutters, of which the following is a specification:
This invention relates to rolling shutters; and consists in securing the slats or laths to each other, edge to edge, by means of bands of steel or other suitable material passing transversely in mortises through the slats, and jagged or cut in such a manner as to form a series of barbs or teeth, each inclined in the same direction. The bands are inserted in the slats by passing them backward, with respect to the barbs or teeth, so that their points extend opposite to the direction of insertion and form a succession of inclined planes which move readily past the sides of the mortises. When, however, the bands are drawn into their proper places, the projecting points of the teeth prevent any motion of the bands in the opposite direction, because they will engage the sides of the mortises in that direction, and consequently the slats or laths are held securely to each other and to the bands, and, as the bands are elastic, they permit the slats to be rolled or wound up, their edges being fitted with a rounded ton gue-and-groove joint which permits the slats to move on each other at their edges, and serves to conceal the bands where they pass through from the front edge of one slat to the back edge of the next.
This invention is illustrated in the accompanyin g drawing, in which Figure l is an elevation of aportion of a shutter made according to my invention. Fig. 2 is a vertical section thereof, taken in the plane of the line :10 a: of Fig. 1.
Similar letters indicate corresponding parts.
The letter A in -these drawings designates the shutter, composed, in this example, of narrow slats B, of wood, to which material for such shutters my invention is especially suitable. The slats are arranged edgewise to each other, the edge 0 of one slat being rounded and placed in a groove, D, made in the adjacent edge of the next slat, so that the edges of the groove of one slat will overlap and conceal the edge 0 of the other slat, and yet permit the free movement of the slats on each other at their adjacent edges. The slats of the shutter are mortised transversely from edge to edge, as indicated in dotted outlines, there being as many lines of mortises as there are bands to be employed. In this example there are three lines of mortises, E, to receive three bands, F, on which the slats are mounted. The bands F are, preferably, made of steel or other metal possessing a good degree of elasticity and strength, provided with teeth G, which may be produced, as in this example, by cutting or punching and forcing out on one side a series of angular teeth from the body of the band at suitable intervals, according to the width of the slats, so that there will be a tooth for each slat. The bands may, however, be serrated or provided with teeth in any other convenient manner which will accomplish the result sought after. The teeth on any particular hand must point in the same direction.
The slats having been prepared and mortised, and arranged edge to edge, toothed bands F are drawn, in the manner above described, through the mortises at the ends of the slats in the direction of the arrow, and another band is then drawn through the central mortises in the reverse direction, the c0nstruction and arrangement being such that the slats are automatically engaged by the teeth of the bands, so that they cannot shift from their places nor move laterally on the bands; but, by reason of the elastic nature of the bands and the character of their fastenings, the slats are free to move on their joints when the shutter is rolled up.
The ends of the bands are fastened to the upper and lower slats of the shutter by means of a screw, H, or other fastening, and the ends of the mortises are concealed by strips like that shown at I.
What I claim as new, and desire to secure by Letters Patent, is-
The toothed bands F, arranged in the slats of a rolling shutter so that the teeth of one or more of the bands point in opposite directions from the teeth of the other bands ot the shutter, substantially as set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 19th day of August, 1874..
J AS. G. WILSON.
