EDWARD MATTOGKSOF LYNDON, VERMONT.

SHUTTER-OPERATOR.

Specification of Letters Patent No. 27,458, dated March 13, 1860.

To all whom it may concern:

Be it known that I, EDWARD MATTooKs, of Lyndon, in the count-y of Caledonia and State of Vermont, have invented a new and useful Improvement in Operating TWindow Blinds, Shutters, &c.; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which- Figure l, denotes a front elevation of a window frame having a blind applied thereto and provided with my improvement. Fig. 2, is an inner side elevation of the window fame showing the head of the guiding tube. Fig. 3, is a side view of the guide tube to be hereinafter described.

The nature of my invention consists in applying to a window frame and blind, certain. devices (as hereinafter set forth) for controlling the movements of the said blind, whereby it may be unlatched, opened oi closed, and relatched, without the necessity of raising' the sash of the window.

In the drawings above mentioned, A, represents a window frame (provided with a sash) and having a blind, B, hinged or applied thereto in the ordinary manner. From the lower side of the said blind, a spring catch bar, D, is attached, the same having a double catch, (o, a, constructed and disposed upon its outer end inthe usual way. Near the lower part of the window frame, A, and transversely thereof, a hole or passage, c, is formed, and within the same a cylindrical pipe is placed, and properly secured.

Through this latter pipe, the longer arm, (Z, of a rectangular tube, C, is disposed, the same being of such size as to be capable of being readily revolved, as well as slid longitudinally therein. On the inner end of said longer arm, (Z, a button or milled head, e, is secured, the same being for the purpose of actuating the said tube, C. The object of this peculiar formation and arrangement of the tube, C, is to obtain a ready means whereby, by the use of a single tube and cord, the line of traction may be varied so that the blind may be either drawn toward the window, or pulled backward therefrom,

as circumstances may require. Through the said tube a cord or rope, f, is carried and has one end attached at or near the outer part of the spring bar, D, or that which carries the double catch, the other end of such cord projecting from the button or head, o, as seen in Fig. 2.

Having thus described the construction of my invent-ion, I will now describe its operation.

If we suppose the blind to be closed, and we desire to open the same and fasten it back or to the side of the building, to which it may beapplied, we iirst grasp the button, e, on the inside of the window frame and push the tube outward; we next pull on the cord suiiiciently to slightly depress the spring catch bar, D, or enough to throw the catch out of engagement with its fastener; next we cause the tube to make one half of a revolution, or move through an are of ninety degrees, the shorter arm of the tube sweeping downward in the movement; next, pull upon the cord to cause the blind to swing around or into a proper position for being locked or fastened; next draw in the tube and cord, and the operation is completed.

From the above it will be seen that the object aimed at, is accomplished in a simple, easy, and edective manner, and that the mechanism employed is also very simple, and not liable to derangement.

Vhat I claim is- The combination of devices herein set forth, for controlling the movements of a window blind, whereby it may be unlatched, opened or closed, and relatched, (as circumstances may require) such devices being the rectangular tube, C, the spring catch bar, D, and the cord, f, the same being arranged and made to operate together, substantially in manner as set forth.

In testimony whereof I have hereunto set my signature this 25 day of July A. D. 1859.

EDWARD MATTOCKS.
