SHUTTER-WORKER.-

SPECIFICATION forming part of Letters Patent No. 439,912, dated November 4, 1890.

Application tiled May 29,1890. Serial No. 353,662. (No model.)

To a/ZZ whom it may concern.-

' Be it known that I, ALEXANDER F. WARD, a citizen of the United States, residing at Detroit, in the county of Wayne, and State of Michigan, have invented certain new and 4useful Improvements in Blind-Operators, of

which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in blind-operators; and the invention consists in providing an ordinary window-blind with a plate carrying a gear adapted to mesh with another gear secured to the Window-casing, and suitable mechanism for operating said gears from the inside of the casing to either open or close the blind and lock it in any adjusted position without the necessity of opening the window.

The invention further consists in providing means for opening or closing the slats by the same mechanism used to operate the blind, and, still further, in the peculiar construction, arrangement, and combination of parts, all as more fully hereinafter described, and shown in the drawings, in which Figure l is a diagram front elevation of a window frame and blinds to which my improvement is attached, showing the blinds in several dilferent positions. Fig. 2 is a side elevation of a portion of a window casing, blind, and my improved operator. Fig. 3 is an enlarged front elevation, partly in seotion, showing the slat-operating mechanism. Fig. 4 is a plan with the blind shown in dotted lines. Fig. 5 is an enlarged vertical section on line a: a, Fig. 4. Figs. 6 and 7 are detail perspective views, more specifically referred to by letters of reference.

A is a window-casing; B, are blinds; C, the ordinary hinge, and I) my improved blindoperator, which is preferably formed integral with one of the hinges and consists of the following parts: E and E' are plates, the former being attached to the casing and provided with an arm a, terminating in a socket a', and the latter secured to'blind carrying the pin-gear F and pivot b, which engages in the socket a.

G is the shaft extending through the casing A, the inner end of which is provided with a knob G. On the outer end of this shaft are sleeved the gear-wheels H and I, the former being nearest the casing and provided on its inner side with a hub c, engaging in a suitable aperture or cut-away portion c in the plate E and on its outside with the recess'd, while the latter meshes with the pin-gear F.

e is a pin secured to the shaft G, which is normally in the recess cl, butis adapted to be engaged in suitable notches e and e" in thegear-Wheels H and I, respectively, by a suitable movement of the shaft, thus forming a clutch mechanism, by means of which either gear may be rotated with the shaft.

J is a spring bearing against the outside of the gear I and adapted to hold it normally in contact with the gear H. K is the lug, preferably secured to the arm a, engaging with the teeth of the gear I in its normal position and acting as a stop to preventit from being rotated.

L is a rock-arm centrally pivoted at f to the plate E', one end of which is connected by the link M and bracket N to one of the slats of the blind, and the other end terminating in a segmental gear O, adapted to mesh with the gear-wheel I-I.

The bearing k for the pivot is preferably slotted and contains a spring g, which normally holds the gear in mesh, but will allow them to be thrown out under sufficient strain.

In practice the operation of the device is as follows: The normal position of the parts in either the open or closed position of a blind is as shown in Fig. 5., the gear I being held in close contact with the gear I-l by the tension of the spring J, in which position it is locked from turning by the lug K. If the operator wishes to change the position of the blind, he rst presses on the knob G', which, through the medium of the shaft G and pin e, forces the gear I out of engagement with the stop K, and by then turning the knob in one way or the other the pin c is engaged in one of the notches e and the gear I rotated, which in turn moves the pin-gear F, thereby opening or closing the blind. As soon as the knob G is released, the tension of the spring .I will force the gear I into engagement with the IOO stop K and lock it from further movement; When the blind is in its closed position, the gear H is in mesh with the segmental gear O, as shown in Fig. 3. If the operator then wishes to open or close the slats, he first draws in the knob G bringing the pin e into contact with the gear H, when by turning thei former the pin e will be engaged into the notches e of the gear H, and in its further movement the Slat will be moved through the medium of .the rock-arm L, link M, and bracket N.

Although I have shown my device as applied to a hinge, it is vevident that it could be entirely independent thereof; but in practice I iind it advantageous to combine the two. It is also evident that any clutch mechanism may be employed which would enable me to operate either of the gears independent of the other in place lof the one shown and described.

What I claim as my invention is- 1. Ina blind-operator, the combination,with a rotary sliding shaft, of two independentlymovablegear-wheels loosely mounted thereon, a crown-wheel rigidly secured to the blind with which the outer gear meshes, a spring for normally holding the same outof engagement,

said gearwheels on the shaft, and means `on the blind for engaging the inner gear to .op-

erate the slats, substantially as described r2. In ablind-operator, the combinaton,with a rotary sliding shaft, of t-wo independentlymovable gear-Wheels having notches in their inner faces, pins -on said shaft for engaging in said notches, a yspring for normally holding the outer gear in contact with the inner one,

the gear upon the blind, of an intermeshing movable gear-wheel slidingly secured upon the drive-shaft held in a normally-locked position by engaging with a stationary abut-- ment, and mechanism for releasing said gear and rotating the blind, substantially as described.

4. In a blind-operator, the combinatiomwith the inverted crown-wheel F, rigidly secured to the blind, of the wheel I, slidingly secured on a shaft adapted to mesh with the wheel F, the stop K, adapted t0 engage with wheel I and retain the same in astationary position, spring J, for normally holding said wheel in contact with the lug, and aclutchmechanisrn between the said shaft and gear-wheel, substantially as described.

5. The combination of the shaft G, extending lthrough the casing, the gear-wheel H, loosely secured thereon, a lever upon the blind connected at one end to the shutters and carrying a rack at the otherend adapted to ymesh with the gear-Wheel H, said rack having a slot in which .the pin f is permitted to -slide,.and a spring-in said slot bearing against j said pin to normally hol-d the rack in its eX- tended position, .substantially as described.

6. The .combination of the `shaft G, extending through the window-casing, the gear-wheel H, a clutch for connecting the two, a lever piv- `oted upon the blind, having a slot therein, and

a spring in saidslot for normally holding said v s llever in mesh with said wheel H, connected pins on the shaft for engaging and locking :atone end to theshuttersand carrying a rack at the other end adapted to mesh with the gear-wheel H, `substantially as described.

7. The combination ot' the shaft G, gearwheels H and I, vthe pin e upon the shaft, recesses in the gear-wheels with which said pin is adapted to engage, the gear F, vmeshing with the wheel I, spring J, stop K, slotted ley ver having spring-bearing for its fulcrum, the `rack at one end of said lever meshing with `the wheel H,.and a connection between the `blind and the other end of said lever, substantially as described.l

In testimony whereof Iafix my signature .in presence of two witnesses.
