UNITED STATES PATENT OFFICE.
JOSEPH BOHRER, OF PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT IN SUSPENDING VENETIAN BLINDS.
Specification forming part of Letters Patent No. 7,408, dated June 4, 1850.
To a/ZZ whom it may concern:
Be it known that I, JOSEPH BOHREE, ot' the county of Philadelphia, in the State of Pennsylvania, have invented a new and Improved Kind of Venetian Window-Blinds; and I do hereby declare that the following is a full and exact description of the same, lreference being had to the annexed drawings, making a part of this specification, in whichw FigureI represents one of my blinds when lowered, and Fig. II all its peculiarities and advantages.k
To both Figs. I and II the pulleys to wbe found in allVenetian blinds are marked a,b, c, and d, and the cord by means of which the blind is either hoisted or lowered is marked A A. Three additional pulleys (marked @,f, and g) are connected with an additional cord B B. By loosening the cord B B the slat next the top of the blind becomes detached from the top, and all the other slats under it resting upon each other move with it simultaneously downward until their further progress is stayed by fastening the cord B B to the knob. This can clearly be seen in Fig. Il, where D D represents the uppermost slatdetached from the top of the blind. l h hare the cords passing through the slats and common to all blinds. t'z'are 4two additional cords, passing only through the uppermost slat D D. la and Z are the pulleys upon which the whole blind works. C C is the cord by which the light is regulated, as in other blinds. Having lowered the .slats to any desirable distance, as seen in Fi'g. II, by loosening the'cord BB, they may instantly be connected Wit-h the top by pulling the cord B B downward until the uppermost slat D D reaches the 'top of the blind.` The lowering and hoisting t-he slats by detachin g them from or connecting them with the top may be done as often and as quickly as the lowering and hoisting of an ordinary blind. When thecord B B is left undisturbed, the blind works as an ordinary one.
The advantage of this improvement is obvious, no elevated positions being required by the person who is cleaning the blind, as all the slats can by loosening the cord B B be yinstantly brought within reach. Moreover,
JOSEPH BOHRER. Witnesses:
GEo., W. Asn, L. ARUMBHAAR.
