Description

(No Model.) A. BOOKEL & E. LOOHMANN. SLAT FOR ROLLING SHUTTERS.
No. 422,707. Patented Mar; 4, 1890 UNITED STATES PATENT OFFICE.
AUGUST BUCKEL, OF ERFURT, PRUSSIA, AND ERNST LOCHMANN, OF LEIPSIC, SAXONY, GERMANY.
SLAT FOR ROLLING SHUTTERS.
SPECIFICATION forming part of Letters Patent No. 422,707, dated March 4, 1890.
Application filed October 21, 1889. Serial No. 327,683. (No model.)
To all whom it may concern:
Be it known that we, AUGUST BocKEL, of Erfurt, in the Kingdom of Prussia and German Empire, and ERNST LOCHMANN, of Leipsic, in the Kingdom of Saxony and German Empire, have invented new and useful Improvements in Slats for Rolling Shutters, of which the following is a specification.
The improved slat for rolling shutters con stituting this invention, and which is also applicable for partition-curtains, coverings for hot-house roofs, seats for garden-chairs, and the like, has the advantage over similar devices heretofore in use, in that it admits of being made up in the form of a flexible chainlike web and is self-fixing instead of being held together by canvas, hinges, or like contrivances, the slats being fitted endwise one into another and being interchangeable.
In the accompanying drawings, Figure I is an end view of one of the slats. Fig. II is an end view showing a series of seven such slats fitted together in the form of an arc of a circle.
Fig. III shows an elevation of part of a roll ing shutter formed by the slats.
Each slat is formed on one of its longitudinal edges with a tongue or round bead a. The other side of the slat is enlarged, and is provided with a longitudinal groove 5, formed between the curved lips c and (l, the distance between the edges of said lips being less than I only great simplicity in manufacture but also permits of rapid and easy fitting together and ready replacement of damaged parts.
What we claim as new, and desire to secure by Letters Patent, is r A slat for rolling shutters, formed with a round tongue or bead along one edge and an open groove along the other edge, the mouth of the groove being smaller than the interior, whereby the groove is adapted to hold and permit of movement within it of the tongue or bead of a like slat fitted endwise into it,
substantially as set forth.
In witness whereof we have hereunto set our hands in presence of two witnesses.
AUGUST BOOKEL. ERN$T LOCHMANN. Witnesses:
CARL BORNGRAEBER, THEODOR SOHUMANN.
