UNITED STATES PATENT OEEIcE.

G. G. MORTON AND E. LAMASURE, OF PHILADELPHIA, PENNSYLVANIA.

DEVICE FOR CLOSING AND OPENING SHUTTERS.

Specitication forming part of Letters Patent N0. 419,909, dated September 12, 1865.

To all whom t may concern Be it known that we, G. G. MoEToN and E. LAMAsURE, of Philadelphia, Pennsylvania, have invented an Improvement in Devices for Opening and Closing Shutters; and we do hereby declare the following to be a full, clear, and exact description ofthe same, reference being had tothe accompanyingr drawings, and to the letters ot' reference marked thereon.

Our invention consists ot' a device, fullydescribed liercinafter, for opening, closing, and retaining shutters.

In order to enable others skilled in the art to make and use our invention, we will now prooeed to describeits construction and operation.

On reference to the accompanying drawings, which forni a part ot' this specification, Figure lis a sectional elevation, representing thelower portion of a window frame and shutter with our improved device for opening and closing the shutter; and Fig.2, a sectional plan on the line l 2, Fig. l. I

A represents a portion oi' the wall of a building, to which is secured a window-frame, B, of the ordinary construction, C being the usual sill, beneath which is a metal casing, D,extend ingl nearly through the wall A.

To the window-trame is hung the usual shutter, E, the lower hinge, F, of which consists ot' the two portions a and a', the former being secured to the frame and the latter, which rests on the portion a, being attached to the shutter.

In the portion a ofthe hinge F turns a rod,

G, the upper square end of which fits into a square opening in the portion a of the hinge, so that the rod cannot be turned without Inoving this portion of the hinge as well as the shutter. The lower portion of the rod G passes through the casing D and through a horizontal worm-wheel, H, in the same, and into the teeth ofthe said wheel gear those of a worm, b, on a shaft, I, the latter extending through the easing and into the interior ofthe building, where it is provided with a crank-handle, J.

When it is desired to close the shutter the crank J and the rod I and its worm are turned so as to impart a rotary motion, in the direction of the arrow, Fig. 2, to the wheel H and its shal't G, by which means the shutter will be gradually brought toward the window -t'raine, the shutter being opened by reversing the inotion ofthe shat't.

It will be seen that by this device the opening and closing of the shutter may be readily effected Jfrom the interior ofthe building` without the necessity otq raising the window-sash, and that the appliances used are such as can easily be operated even by a child.

It will also be seen that the device can be readily applied to any of the shutters now in use, and that the shutter may be readily removed when the saine has to be repainted or repaired.

A most important feature of our invention is the reten tion by the worm ofthe shutter in any position to which it may be adjusted.

We claim as our ini ention and desire to secure by Letters Patentl. The casing I), constructed and arranged as and for the purpose set forth.

2. In combination with the subject-matter of the above, the worin-wheels b and H, piutle G, and crank-shaft I, substantially as set forth.

In testimony whereofl we have signed our names to this specification in the presence ot two subscribing witnesses.

GEO. G. MOlt'lON. EDWIN LAMASURE.
