APPARATUS FOR MOVING .AND` SECURING` `Sli-IU'JT'.IIIERS, &c.

` Specification/ ofiLetters Patent 1\To. 7;,998, dated March 25, 1185,1. A

T0 all whom t may concern: y

Be it known that I, N. W. SrEERs, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful apparatus for opening and closing window shutters from the inside of the house to which they are attached and fastening. them at any desired point in their semicircuit without raising the sash, whichiis described as follows; reference being had to the annexed drawings of the same, making partof this specification. i i

Figure 1, is a topor birdS-eye view of the apparatus applied to a window; the sill and shutter of the window being represented in horizontal section. Fig. 2, is a section of the salne at the line ag of Fig. 1. Fig. 3, is a top view of the apparatus, applied vto a window shutter hinged or hung in the ordiy their semicircuit, and secured, when closed,

against all danger of being opened from the outside. i

To enable others skilled in the art to `make and use my invention, `Twill proceed to de-l scribe its construction andmode` of application. i

A is the lower portion of the frame of the window.

B is a horizontal metallic screw shaft inserted in an opening, formed by an auger, diagonally through the frame, and turning in suitable metallic boxes at its ends, secured in the window. frame. These boxes may be either connected to the extremities of a cylindrical or rectangular metallic casing C, having` i a movable top and inclosing the screw shaft B, andfastened at its outer end to the window frame as represented in Fig.

1; or the casing `may be dispensed with and E is a metallic nut surrounding the screw shaft which passes through the same, connected by a pin at its lower part to a horizontal bar or arm F, extending through a space in the window frame to the outside of the same and attached at its outer end by a pin to a metallic plate or arm Gr, secured by screws to the lower edge of the shutter, and extending at right angles from one wing of the lower `hinge of the shutter, which is in this case (when the hinge and apparatus are cast together to be applied to a new shutter, as represented in Fig. 1) secured at the extreme lower end of the shutter-the other wing of the `hinge being cast with, or otherwise attached to the plate H to which the casing is connected, which secures it firmly to the window fram`e.` 4

In case it is desired to apply this principle of apparatus toa shutter hung on the ordinary hinges, it is formed` after `the manner of the section marked Fig. 3, in the annexed drawings; the plates or armsGr, H, being cast distinct from the wings of the hinge.

In applying the-.apparatus to a window, it is only necessary to mark on the lower portion of the frame the distance from the axis on which the shutter moves to the point on the outer face of the frame where the line of the screw shaft is to intersect, and ascertain on the inner surface of the frame where the line is to intersect there, and after arriving at these points to bore an auger hole through the frame suitable to receive the screw shaft and its attachments; said hole being afterward covered on the inside by a brass, silver, or other plate, perforated to allow the entrance of the key D, and on the outside by the plate. The crank or key for turning the screw shaft may be made as represented, or ofany ornamental form desired.

When it is desired to either open or close the shutter the crank or key D is either turned to the left or right as the? case may be, causing the metallic nut E to be moved out-or in, forcing orldrawing the shutter with it in its movements with a speed and power commensurate with the angle of the threads of the screw with the line of the shaft on which they are formed.

After the shutter is `once moved to the position desired, either entirely open, or closed, or at any intermediate point, it will be held there iirmly by thebar or plate F attachedV to the nut E, through whose agency it was moved-the binding of the nut on the screw shaft B, preventing it from moving either Way, Without the screw shaft being turned.

What I claim as my invention and desire to secure by Letters Patent is The manner of opening and closing` Window shutters from the inside and securing them firmly at any point in their semicircuit by means of the horizontal screw shaft B inserted in an opening in the lower portion 10 of the Window frame, metallic nut E surrounding the same7 and the bar or plate F attached to the shutter, substantially as described.
