Description

0. L. RAINHART. Blind Adjuster and Fastener! (ModeL) No. 230,496. Patented July 27, 1880.
INVENTOR ATTORN Y UNITED STATES PATENT OFFICE.
CHARLES L. RAINHART, OF OAT SKILL, NEW YORK.
BLIND ADJUSTER AND FASTENER.
SPECIFICATION forming part of Letters Patent No. 230,496, dated July 27, 1880.
' Application filed April23,1880. (ModeL) To all whom t't may concern:
Be itknown that I, CHARLES LEROY RAIN- HART, of Catskill, in the county of Greene and State of New York, have invented a new and useful Improvement in Blind Adjusters and Fasteners, of which the following is a specification.
Figure l is a side elevation of the improvement, showing the blind opened. Fig. 2 is a sectional plan taken through the line a; a Fig. 1. Fig. 3 is the same section as Fig. 2, but showing the blind closed.
Similar letters of reference indicate corresponding parts.
The object of this invention is to furnish blind adjusters and fasteners so constructed as to hold the blinds in any position into'which they may be adjusted, hold the blinds from rattling, and be operated from the inside of the window, and without raising the sash.
The invention consists in constructing a blind adjuster and fastener of a gear-wheel carrying a bar having an arm hinged to its outer end, the keeper to receive the arm, the jointed rack-bar having slots in its inner part, the wedge-key, and the socket, whereby the blind can be adjusted and fastened from the inside of the window.
A represents the sill, and B the frame or casing, of a window. (J represents the blind, which is hinged to the casing B in the ordinary manner, and with any desired kind of hinges.
To the sill A, near the side of the casing B, is pivoted a gear-wheel, D, which is attached to or formed upon the widened inner end of a bar, 15.
To the outer end ofthe bar E is hinged an upwardly-projectin g arm,F, which passes through a long keeper, G, attached to the inner side of G, whereby the blind may be opened, closed,
the bottom rail of the blind O.
The teeth of the gear-wheel D mesh into the teeth of the rack-bar H, which passes through a hole in or beneath the base of the casing B. The inner part of the rack-bar H passes through a keeper, 1, attached to the inner side of the base of the casing 13, and has a number the blind shut the inner part of the said bar H maybe turned to one side along the base of the casing B. to prevent the bar from projecting into the room and being in the way.
To the lower corner of the outer side of the casing B is attached an outwardly-projecting arm, K, the upper side of which is inclined.
When the blind G is swung open its bottom rail will slide up the said arm K, so that the said blind G will be raised and supported by the said arm, and will be held firm and rigid by the adjusting mechanism.
With this construction the blind can be opened and closed and adjusted at any desired an gle'by operating the jointed rack-bar H, and will be held firmlyin any position into which it may be adjusted, so that there will be no rattling.
With this construction the blind cannot be moved in either direction from the outside of the window.
Having thus described my invention, Iclaim as new and desire to secure by Letters Patent An improved blind adjuster and fastener, constructed substantially as herein shown and described, consisting of the jointed rack-bar H, having slots in, its inner part to receive the wedge-key J, the pivoted gear-wheel D, the bar E, having hinged arm F, and the keeper and fastened from the inner side of the window, asset forth.
