JOHN H. MONK, OF BROOKLYN, E. D., NEW YORK.
BLIND-=SLAT ADJUSTER.
SPECIFICATION forming part of Letters Patent No. 234,317, dated November 9, 1880.
Application filed April 29, 1880. (No model.)
To all whom it may concern Be it known that I, JOHN H. MONK, of Brooklyn, in the county of Kings and State of New York, have invented anew and useful Improvementin Blind-SlatAdjusters, of which the following is a specification.
Figure l is a front elevation of theimproven'1ent,illustrating its use. Fig.2 is a sectional elevation taken through the broken line 00 00, Fig. 1, a portion of the case being broken away.
The object of this invention is to furnish an adjuster for the slats of window and door blinds, so constructed that the slats can be adjusted into any desired position and will be securely held in place.
The invention consists in combining, with the frame and the slats of a blind when the said slats are connected by a bar, a forked pivot, a gear-wheel, a sliding rack, a knob, a double springmwl, a stationary rack, and thumb-pieces, whereby the slats may be adjusted into any desired position and securely held in place, as will be hereinafter fully described.
Similar letters of reference indicate corresponding parts.
A represents the frame, and B the slats, of a blind. The corresponding corners of the slats B are pivoted to a bar, 0, so that all the slats will move together. All the pivot-holes in the bar 0, except the hole for the pivot 01" one of the middle slats, B, are elongated, as shown in Fig. 2, to give the pivots such a play as will allow the slats B to shut together closely in either direction.
To the end of one of the slats B is attached the forked end of a metal pivot, D, which .passes through a hole in a plate or case, I at tached to the side bar of the frame A, and enters a recess in the said bar.
To the end of the pivot D is attached a small gear-wheel, F, into the teeth of which mesh the teeth of a rack, G, so that the gearwheel F, and withit the slats B, may be turned by the longitudinal movements of the rackbar G. i
To the center of the rack-bar G is attached the shank or stem of a knob, H, which shank passes through a slot in the outer part of the case E.
To the shank of the knob H, at a little distance from the case E, is attached the center of a spring, I, the ends of which are curved inward to engage with teeth or corrugations J, formed in the outer part of the case E, orin a plate attached to the said case E.
To the end parts of the spring-pawls I are attached thumb-pieces K, for raising the said spring-pawls I away from the rack-teeth J.
With this construction, by drawing the thumb-pieces K toward the knob H and moving the said knob up and down, the slats may be folded together or closed, or may be adjusted in horizontal positions or at any desired angle, as circumstances may require.
WVith this construction, also, when the slats B are folded together they cannot be opened from the outside of the blind.
Having thus fully described myinvention,I claim as new and desire to secure by Letters Patent- 1. In a blind'slat adjuster, the combination, with the shank of the knob H, to the inner end of which is attached the sliding rack G, of the stationary rack J and the spring-pawls I, attached to the said shank, and provided with the thumb-pieces K, substantially as and for the purpose set forth.
2. The combination, with the frame A and the slats B, connected by a bar, 0, of the forked pivot D, the gear-wheel F, the sliding rack G, the knob H, the spring-pawls I, the stationary rack J, and the thumb-pieces K, substantially as herein shown and described, 8 5 whereby the slats may be adjusted into and held securely in any desired position, as set forth.
JOHN H. MONK.
