SHUTTER-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 407,845, dated July 30, 1889.

Application filed March 21, 1889. Serial No. 804,131. (No model.)

To all whom it may concern.-

Be it known that I, THEODORE THORN, a citizen of the United States, residing at St. Clair, in the county of Schuylkill and State of Pennsylvania, have invented new and useful Improvements in lVindow-Shutter Holders, of which the following is a specification.

My invention relates to improvements in window-shutter holders; and it consists in certain novel features hereinafter described and claimed.

In the accompanying drawings, Figure 1 IS".

a perspective view showing awindow-shutter partly open and held by my improved device. Fig. 2 is a horizontal section showing the shutter fully opened. Fig. 3 is a detail perspective view of the supportingor base plate.

The window-frame A and the shutters B are of the usual or any preferred construction, and the shutters are secured to the window-frame by the ordinary hinges C, as shown. A supporting or base plate D is secured to the Window-frame, and is provided at one edge with a cylindrical stud or pivot pin E, on which the holder or fastening-bar F is pivoted. This fastening-bar F is composed of two sections or members G G, which are hinged together at their meeting ends and extend through a guide or keeper plate H, secured to the shutter. A set-screw I is mounted in the guide-plate II, and is adapted to bear against the fastening-bar to bind it against the shutter. The inner edge of the shutter is cut away to form a recess J, through which the fastening-bar moves as the shutter is opened or closed, and the said recess is lined with rubber, so as to reduce the wear between the contacting parts. The inner member or section G of the fastening-bar is about equal in length to the distance between the pivot-pin of the base-plate and the edge of the shutter when it is entirel open, so

- that the fastening-bar will fold around the fastening-bar will extend to a straight line through the guide or keeper plate, and the set-screwis turned up against the bar to bind it against the shutter. The keeper or guide plate will thus be prevented from moving over the fastening-bar, and the shutter consequently secured in its closed position. As the shutter is opened, the fastening-bar will swing around on its pivot and at the same time will be drawn through the keeper-plate. The shutter is secured at any desired point by turning the set-screw up against the bar, so as to bind it against the shutter. When it is desired to remove the shutter for any reason, it can be readily lifted and the fastening-bar at the same time lifted from its pivot-pin without necessitating the removal of any securing-screws.

The fastening-bar being made in two sections hinged together, readily accommodates itself to the position of the shutter, and when clamped against the shutter by the set-screw effectually prevents movement of the shutter. My device is very simple and its advantages are thought to be obvious.

Having thus described myinvention, What I claim, and desire to secure by Letters Patent, 1s

1. The combination, with the shutter and the window-frame, of the keeper-plate secured to the shutter, the fastening-bar hinged to the window-frame and passing through the keeper-plate and provided with a series of vertical ribs on its outer side, and the setscrew mounted in the keeper-plate and having its inner end engaging between the ribs on the fastening-bar, as set forth.

2. The combination, with the shutter having a rubbenlined recess J and the windowframe, of the keeper-plate secured on the shutter, the fasteningbar pivoted to the window-frame, playing in the recess J and passing through the keeper-plate, and the setscrew mounted in the keeper-plate and bearing upon the fastening-bar, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two Witnesses.

THEODORE THORN.
