IMPROVEMENT lN SHUTTER-WORKERS.

Specification forming part of Letters Patent No. 138,879, dated May 13, 1873; application filed February 12, 1873.

To all whom it may concern:

Be it known that I, AUGUSTUS H. Games, of Norwalk, in the county of Fairfield and State of Connecticut, have invented a new and Improved Device for Operating Window- Shntters; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled. in the art to make and use the same, reference'being had to the accompanying drawing forming part of this specification, in which drawing- Figure 1 represents a horizontal section of this invention. Fig. 2 is a transverse vertical section of the same.

Similar letters indicate corresponding parts.

This invention consists in combining with a v'indow-shutter a bell-crank lever, which has its fulcrum on a pivot secured in the windowsill outside of the window, and one arm of which connects by a link with a bracket secured to the shutter, while its other arm connects with a button that slides in a segmental slot in the window-sill inside of the window, in such a manner that, by moving the button in its segmental guide-slot, the shutter can be opened or closed without opening the window. The button is so arranged that it can be secured in any part of its guide-slot so as to retain the shutter in any position into which it may be brought.

In the drawing, the letter A designates a shutter, which swings on hinges a in the usual manner. Close to the lower hinge is a bracket, 1), secured to the shutter, and this bracket connects, by a curved link, c, with one arm, (I, of the bell-crank lever (Z c. This bellcrank lever has its fulcrum on a pivot, f, secured in the window-sill outside of the window, and its arm 0 connects with a button, g, which slides in a segmental guide-slot, h, in the windowsill inside of the window. By moving this button in its guide-slot the shutter is opened or closed. The button 9 is screwed into the arm 0 of the bell-crank lever, and it is provided with a flange which bears on the surface of the guide-plate h, so that by screwin g up said button the arm c is drawn up tight against the inner surface of the guide-plate, and the shutter is retained in the position which it may occupy.

When the shutter is constructed in two halves, as shown in the drawing, each shutter is provided with its distinct device for open ing, closing, or fastening the same; and I am enabled to secure the shutters in their closed position or in their open position, or in any intermediate position in which the same may be brought; furthermore, the shutter can be operated without raising the windows, and the ordinary devices for retaining the shutters when the same are open or closed can be dispensed with.

My device has also the great advantage that it does not produce any objectionable projection on the interior of the window-frame, and, if properly constructed, it will form an ornament for the window.

I do not claim a chain, made up of a series of links, Working in a guide and operated upon by a thumb-screw for opening and closing a shutter; neither do I claim, broadly, operating a shutter from the inside of the windowsash by means of the two pivoted curved 1evers, for such devices are old and well known, and require much strength to operate them, besides, the operating-lever projects on the interior beyond the sill, and while the 1necl1- anisrn upon the shutter and its lever are exposed on the outside, thus disfiguring the finish of the shutters.

What I claim as new, and desire to secure by Letters Patent, is

1. The bell-crank lever d c pivoted at f on the outside sill, one arm of which is pivoted to the curved link 0 of the bracket b, while its other arm connects with the adjustable button g, moving in the guide-plate h, secured to the sill inside of the Window, the whole combined and arranged, substantially as described, for operating a windowshutter or blind, as set forth.

2. The bell-crank leverd e pivoted at f on the outside sill, in combination with the curved link 0, said link being pivoted to the bracket and to the lever, as shown, for operating in connection with the button g moving in the guide-plate h arranged on the sill inside of the window, the several parts being constructed, substantially as described, for opening and closing a window-blind, as set forth.
