UNITED rSTATES PATENT OFFICE AMOS A. JAQUA, OF NEW YORK, N. Y.
IMPROVEMENT IN WINDO'WK-BLINDS, 84C.`
Specification forming part of Letters Patent No. 156,400, dated October 27, 1874; application filed September 272, 1874.
To all whom it may concern:
Y Be it known that I, AMoS A. J AQUA, of the city, county, and State of New York, have invented a certain new and useful Improvement in Device for Holding and Operating Blind- Slats from their Ends; and to enable others skilled in the art to make the same, I will proceed to describe it by referring to the drawing, in. which the same letters indicate like parts.
The object of this invention is to secure and operate the slats more perfectly than has hitherto been done; and to this end it consists, more particularly, in a slat having one round and one square tenon, in combination with a suitable orifice, pinion, rack, and case, all constructed and operated as will hereinafter be more fully and particularly set forth.
. A is an elongated plate or case, having riinedges E and bearing-orifices B to receive the hub-bearings B ofthe pinion O. F is a rack, the teeth of which are itted to work into and between the teeth of the pinion O and the rim said slats is rounded in the common way. The
opposite end is left square to be compressed into a squareor oblong orifice of a pinion or tooth Wheel. This pinion is provided with hubbearings on each side, which are tted closely and turn freely'in bearing-orifices in the elongated case and cap, which is secured into a rabbet or groove formed in the edge of a door or b1ind-stile, where the Vslats are to work. A tooth-rack is tted into said case, between the rim of the. case and the pinion, so that the pinion-teeth shall t closely and Work freely in the teeth of the rack, and so that the pinion, through the action of the rack, will operate the slats to open and close uniformly one with the other, and the slats may lbe locked in an open or closed condition by a thumb or lever catch working into the teeth of the rack at any desired point. v
These slats, operating-rack, and pinioncase may be'arranged and secured in the edge of the stile of the door or blind at the time of putting the frame together, or afterward, as desirable.
What I claim, and desire to secure by Letters Patent, is-
l. The case A, rack F, pinion O, having square orifices G in the bearing-hubs B to receive the square tenon G, substantially as and for the purpose set forth.
V 2. A slat having one round land one square tenon, in combination with a square orifice, pinion O, rack F, and case A, as and for the purpose set forth.
AMOS A. J AQUA.
