To all whom it may concern Be it known that I, JOSIAH QUINCY NEW- HALL, ot' Medford, in the county of Middlesex and Commonwealth of Massachusetts, have invented a new and useful Blind-Stop for securing movableblind-slats in any desirable position and I hereby declare that the following is a full and exactdescription.
The nature of my invention consists in a novel combination and arrangement of adj ustable jaws, pin, spring, locking devices, and offset, whereby endwise pressure is obtained and the slats held in desired position, as will be hereinafter more fully described and definitely claimed. a f To enable others skilled inthe art to make and use my invention, I will proceed to describe its construction and operation,usin g the accompanying drawing to aid in the explanation, like letters indicating like parts.
A A on said drawing represent movable jaws, whichclasp around the axle'of the blindslat. B represents a pin, on which the movable jaws A A are swiveled. O is a spiral spring, surrounding the pin, and which presses a the movable jaws A A against the end of the blind-slat D. E E are locks to hold the jaws flush on the slat side. H is an ofl'set on one of the jaws, which acts as a catch to hold the jaws in position when in use, and give a smooth surface for the ends of the slats to turn upon, the operation of the whole being simple and easily understood from the foregoing description.
What I claim as my invention, and desire to secure by Letters Patent, is
1. In combination with the jaws A A, the pin B, the spiral spring 0, the locks E E, and offset H, all constructed as described and shown, and arranged to operate, substantially in the manner and for the purposes herein set forth.
