LAFAYETTE HUNTOON, OF NATIOK, MASSACHUSETTS, ASSIGNOR TO HIM- SELF AND EDWIN 0. HUNTOON, OF SAME PLACE.

SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 241,017, dated May 3, 1881.

Application filed January 19, 1881. (No model.)

To all whom it may concern Be it known that I, LAFAYETTE HUNTOON, of N atick, in the county of Middlesex and State of Massachusetts, have invented certain Improvcments in Blind Operating and Fastening Devices, of which the following is a specification.

This invention relates to attachments for outside window blinds and shutters, by means of which said blinds or shutters may be opened or closed from within the building without opening the window; and it consists in certain improved mechanism for performing said operation and for locking the blind or shutter 1 when open or closed, all of which I will now proceed to describe, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 represents an exterior view of a portion of a blind having an attachment embodying my invention, the blind being closed. Fig. 2 represents a similar view with the blind open. Fig. 3 is avertical section through the wall, the blind being closed. Fig. 4 represents 2 5 a horizontal section. Figs. 5 and 6 represent enlarged views of a part of my invention, Fig. 5 being an elevationand Fig. 6 a plan view.

The same letters of reference indicate the same parts in all the figures. 0 In the drawings, B represents a blind having attached to the under side of its lower rail a plate, a, carrying a metallic stud, c, which is cast upon said plate, said stud being located at a considerable distance from the inner edge of the blind. The stud 0 passes downwardly through a slot, d, in a metallic plate, 0, which plate is rigidly attached to a rod or lever, f, passing through the wall of the house below the level of the bottom of the blind, and having its inner extremity provided with a suitable knob or handle, 9. The leverfis movable transversely thi ugh the wall of the house, and its socket is provided with a suitable rubber packing, f, by means of which regularity of move- 5 ment is secured to the lever f and cold air is prevented from entering the house around said lever. The rubber packing f is maintained in position by the removable plate g, and by removing this plate access may be had to the packing for removing the same, when worn, without disturbing the other parts of the mechanism. The lever-f is jointed at i, so that the inner part of the rod carrying the handle may be brought to a vertical position against the inside ofthe house wall, as shown by the dotted 5 5 lines in Fig. 3, for the purpose hereinafter described. The stud-plate a is attached to the blind by means of a screw, to, (shown in Fig. 5,) cast upon said plate, and the stud 0 has its lower end provided with a foot, 0, adapted to bear upon a metallic shield, 70, attached to'the window-sill A when the blind is closed. The under side of the foot 0 is beveled to conform to the wash of the sill, and so adapted to slide upon the shield 70 when the blind is closed, as described. By means of this shield the sill is protected from injury from the stud c, and the stud c, in combination with the shield k, serves as a support for the blind, thus preventing it from sagging. 70

The operation of my invention is as follows: The blind being closed and the parts in the position shown in Figs. 1 and 3, the rod or lever f is given a quick outward push, thus causing one side of the slot to press against the stud c and push the blind open. hen the blind has swung more than half open, or in other words, passed the center, the rod is drawn inwardly, thus causing the other side of the slot to bear upon the stud 0 and force the blind against the side of the building. A reversal of this operation will close the blind. The blind may be looked in either position by bringing the inner part of the rod or lever f to a vertical position, as shown by dotted lines, Fig. 3, thus preventing the rod from being moved outwardly through the wall. The screw to is offset from the stud c, as shown, so that in rotating the plate a to withdraw the screw a from the blind the stud 0 0 has to move in a circle of greater diameter than the width of the slot (1. iVhen the plate 6 is locked by the outer end of the lever f assuming a vertical position the plate a cannot be rotated, because the sides of the slot cl prevent 5 the stud c from describing the circle in which it must move. It follows, therefore, that the plate a, with its stud 0, cannot be removed from the blind when the plate 0 is locked. The blind is thus prevented from being tampered with from without.

The foot 0 prevents the blind from being lifted upwardly and removed from its hinges by the wind or otherwise, as said foot cannot pass through the slot d.

I am aware that a blind or shutter has been operated from the inside by a sliding rod havslot plays a pin or stud on an arm or lever projecting outwardly from the inner edge of the blind. It is obvious that said arm or lever is neeessaril y very short, so that when the blind swings the outer end of the arm or lever will not strike the building. The pin playing in the slot is therefore close to the axial line of the blind, so that the sides of the slot can exert but a comparatively small amount of leverage on the blind in operatingthe same. By locating the stud c on the bottom edge of the blind I am enabled to place it as far as may be desired from the axial line of the blindsay four or five ing a transverse slot in its outer end, in which inches; and by employing a slot, 61, of suitable length, I obtain all the leverage needed to operate the blind, and also to enable the j ointed lever, when turned down at its inner end, to hold or look the blind firmly.

Having thus described my invention, I claim The combination of thejointed leverf, having a slot in its outer extremity, and the stud c, rigidly attached to the bottom of a blind and having its lower extremity provided with afoot, 0, adapted to bear on the window-sill, substantially in the manner and for the purpose set forth.

In testimony whereof I have signed myname to this specification, in the presence of two subscribing witnesses, this 15th day of Jan uary, A. I). 1881.
