WINDOW-BLIND.
SPECIFICATION forming part of Letters Patent No. 421,047, dated February 11, 1890. Application filed November 30, 1889. Serial No. 332.083. (No model.)
To @ZZ whom it may concern:
Be it known that I, EMIL HANTscHE, Jr., of New York city, New York, have invented an Improved VindoW-Blind, of which the following is a specification.
This invention relates to a window-blind of the kind in which the rod which connects and operates the slats is concealed within the blindframe.
The invention consists in the various features of improvement, more fully pointed out in the claim.
In the accompanying drawings, Figure l is a sectional face View of myimproved blind. Fig. 2 is a vertical section on the line Fig. 1.
The letter a represents .an outer frame which I prefer to use and into which iits an inner frame h. One of the stiles b of this frame is slotted lengthwise to carry the slatoperating mechanism. c c are the slats, pivoted within frame Z9. The pivots d at one end of the slats are of the ordinary straight form; but the pivots d', that enter the slotted stile b', are crank-shaped, as shown-that is to say, the pivots d pass with their shanks through the stile, and are then bent twice at right angles Within the slot of the stile. The upper straight ends of the pivots d are connected by a perforated bar e, concealed within the slotted stile, each perforation engaging one of the pivots, so that the motion of the bar will uniformly operate all the slats. Across the slotted stile bthere is secured, near each end thereof, a plate f, by screws or otherwise. To these plates are pivoted toothed wheels g.
These toothed wheels are perforated, as at g',
to receive each the end of one of the pivots the latter will in turn revolve the two slats v with which they are connected. This motion is by the perforated bar e transmitted to all the slats of the blind to open or close the saine.
- By using a pair of toothed wheels-one near the top and one near the bottom of the blind-I drive the entire series of slats positively and without unduly straining any of the parts.
I prefer to bend the inner ends cl2 of the pivots d to al slight extent where they enter the slats c. As these pivots have to bear the entire working strain, theywo uld be apt to work loose in their seats when made perfectly straight. This difiiculty is overcome by bending them in the manner indicated.
Vhat I claim is- The combination of a blind-frame having a slotted stile with slats c, crank-shaped pivots d', u pon which the slats turn and which enter the slot in the stile, a perforated bar connecting the pivots d', a pair of toothed wheels engaging a pair of said pivots, and a rack engaging the toothed wheels, substantially as specified. l
