SHUTTER- WORKER.

SPECIFIGATION forming part of Letters Patent No. 474,831, dated May 17, 1892.

Application filed August 5, 1891.

To all whom it may concern.-

Be it known that I, ABIJAH H. HULL, a citizen of the United States of America, and a resident of Odebolt, in the county of Sac and State of Iowa, have invented an Improved Shutter-Operating Device, of which the following is a specification.

My invention relates to that class of sh utter-openers described in my application, Serial No. 385,973, filed in the United States Patent Office March 23, 1891.

My invention consists in the combination, with a hinged shutter-blind, of a spring-rod, a stop to engage the spring-rod, and a clip to engage the stop, as hereinafter set forth, pointed out in the claim, and illustrated in the accompanying drawings, in which Figure 1 is an outside view of a hinged shutter-blind closed and with my shutter-operating mechanism applied thereto as required for practical use. Fig. 2 is an enlarged sectional view looking upward from the line a: w in Fig. 1. Fig. 3 is an enlarged rear face View of my clip and stop device for securing the shutter-actuating spring to the outside face-casing of the window.

Referring to the drawings, A designates the stool, and A the window-casing, which may vary in size and style, as desired.

13 and B designate the upper and lower window-sashes, respectively, which are secured in the window-frame in the ordinary way.

0 represents a shutter-blindsecured to the casing A of the window-frame by means of common automatically-locking hinges which look when the shutter-blind is open.

D designates a steel spring-rod, which is preferably circular in cross-section and has angular end portions. One end of the springrod D, preferably the upper, is secured in an angular opening in a clip D which is fixed to the shutter-blind. The central portion of said rod is confined in a circular opening in and supported by a clip D which is fixed to the casing A The other or lower end of said rod is confined in a circular opening in a clip which is fixed to the casing A A dishshaped stop F, having an angular central opening, is placed on the end of the springrod D and is mounted in the bifurcated end $erial No. 401.768- (No model.)

portion of the clip F This opening in the stop F, through which the spring-rod D passes,

to engage a projection f on the stop F, which shoulder f limits the rotation of said stop F in one direction. It is provided that the projection) of the stop F will cease to be engaged by the shoulderf of the clip F just before the shutter-blind drops into the notches in the automatically-locking hinge. A metal plate H, having a central slot H is adj ustably connected to the rear face of the clip F by means of the screw that fastened the clip F to thecasing. Thisscrewpassesthrough theclip F and also through the slot H and when sent home presses the clip F down upon the metal plate H, holding the two parts fixed in the desired position. The metal plate is to take the place of the shoulder on the clip F to engage the projection f on the stop F at different positions when it is desired to increase or decrease the tension on the springrod D to operatelarge or small shutter-blinds with equal facility. It is therefore obvious that the metal plate H may be omitted.

In the practical operation of my invention when the shutter-blind is entirely open the spring-rod D has no power stored therein to effect any movement of the shutter-blind whatever, the projection f on the stop F will be free from engagement with the shoulder f" on the clip F and the spring-rod D will be free to move longitudinally through the opening in the stop F, so that the shutter-blind may be lifted, as required, to unlock the interlocking hinges preparatory to closing the shutter-blind. Swingingthe shutter-blind inward toward the window rotates the springrod D and the stop F, bringingthe projection f on the cam F into engagement with the shoulder f on the clip F attached to the window-casing. This engagement of the stop F with the clip F prevents the further rotation of the lower end of the spring-rod D in that same direction; but the further rotation of the shutter-blind continues to rotate the upper end of the spring-rod D, causing force rod one end of which is secured to the shutter-blind and the other end is confined in a clip thatis secured to the Window-casing, and

a stop placed on the end of the spring-rod to 15 engage a shoulder on the clip, to operate in the manner set forth, for the purposes stated.
