ABIJAH H. HULL, OF ODEBOLT, IOWA.

SHUTTER- -OPENER.

SPECIFICATION forming part of Letters Patent No. 484,098, dated October 11, 1892. Application filed March 23, 1891. Serial No. 385,973. (No model.)

To all whom it may concern;

Be it known that I, ABIJAH H. HULL, a citizen of the United States of America, residing at Odeb'olt, in the county of Sac and State of Iowa, have invented an Improved Shutter- Opener, of which the following is a specification.

The object of my invention is to provide improved means whereby a shutter may be closed, locked, and released from the inside of the room without opening the window.

My invention consists in the combination, with a window-shutter normally held open by yielding pressure, of a crank-shaft located, preferably, at one side of the window-frame and projecting within the room, which shaft is connected to the shutter by means of a rope and is provided with means for locking the same.

My invention. consists, further, in certain details of construction hereinafter set forth,

pointed out in the claims, and illustrated by the accompanying drawings, in which- Figure 1 is side view of the crank-shank and its attendantmechanism and support therefor. Fig. 2 is a perspective view of a portion of a window-frame, having the crank mechanism fixed thereto. Fig. 3 is a sectional view on the line x m of Fig. 1. Fig. 4 is an outside view of the window and shutters, portions of the shutter and frame being broken away to reveal interior parts.

Referring to the drawings, A designates the stool; A the jamb; A the inside face-casing; A the stop; A the parting-bead; A, the blind-stop, and A the outside face-casing of a window-frame, which may vary in size and style, as desired.

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

0 and 0 represent the shutter-sections, which are secured to the casing A of the frame by means of common automaticallylocking hinges, which look when the shutter is open. A plate J, having a hook formed integral therewith and projecting therefrom, is fixed to the top portion of the casing A and the hook engages one end of a lever J which is fulcrumed thereon and pivoted near its central portion to the top rail of one of the shutters. The free end of the lever J 2 is provided with an eye, to which one end of arope J 3 is fixed. This rope J 3 passes fromits point of attachment with the lever through a perforation in the top rail of the shutter a short distance above said lever. From thence the rope passes around a sheave J 4 in the head casing of the frame, near the center thereof. The rope then follows along the saidhead casing to the corner of the window-frame. The rope then passes over asheave and downward along and within a groove formed in the rear portion of the parting-bead A to and under a sheave K which is pivoted within a bearer K which is fixed to the said partin g-bead. The end portion of the rope is then fixed to a reel L, which is loosely mounted on a crank-shaft M, which latter is supported by means of a case N, fixed to the rear side of the jamb A and projects through the casing A and through a plate N fixed to said casing. On the outer end of this shaft M is a crank-handle N fixed thereto, by means of which it is rotated.

The reel L has a plurality of pins 0 projecting from the inner end thereof in the plane of the shaft M, which pins are normally engaged by the projecting ends of a pin P, fixed to the shaft M, to rotate the reel synchronously with the rotation of the shaft.

A sleeve S, carrying a ratchet-wheel S is mounted loosely upon the shaft H between the reel L and the end of the case N, which sleeve has longitudinal slots in its inner end portion to admit the pin P to rotate the sleeve isochronously with the rotation of the said shaft. That end of the sleeve S which is in juxtaposition to the end of the case N fits closely on the shaft M, and a spiral spring T is inserted within the sleeve S and coiled about the shaft M, one end of which spring impinges against the outer end of the sleeve, and the opposite end impinges against the pin F and normally holds said pin in engagement with the pins 0. V represents a pawl pivoted to the inside of the end of the case to engage with the ratchet-wheel S on the outer end of the sleeve 8.. It will therefore be obvious that by rotating the crank-shaft the reel L will be rotated and wind the rope thereon, which operation will elevate the free end of the lever J 2 and cause the opposite end thereof to press upon the hooked plate J, thereby elevating the shutter and unlocking the hinges, after which the continued rotation of the shaft and reel will close the shuter, which is locked by the engagement of the pawl V with the ratchet S A longitudinal movement of the shaft M, compressing the spring T, will release the pin P from engagement with the pins 0, as required, to allow the shutter-blind to be opened. Opening the shutter-- blind revolves the reel backward by the pulling outward of the rope. The longitudinal pressure on the shaft being released, the 'springT will cause it to assume its normal position and the pin P to again engage the pins 0 of the reel L.

I claim as my invention- 1. In a shutter-operating device, the combination, with the shutter, of a reel connected to the shutter by a rope adapted to bewound on the reel and a crank-shaft normally connected to said reel by means of a clutch, for the purposes stated;

2. In a shutter-operating device, the combination, with a shutter and an automatic locking device secured thereto, of a lever pivoted to said shutter and fulcrumed to a hook or stop fixed to the casing and a rope and manually-actuated reel to operate thelever, for the purposes stated.

3. In a shutter-operating device, the combination, with a spring-operated shutter, of a rope fixed to and connecting the shutter with a reel, which latter is normally held in engagement with a manually-actuated shaft by spring actuated clutch mechanism, as set forth.

4. In a shutter-operating device, the combination, with a shutter normally opened by yielding pressure fixed thereon, of a rope fixed to and connecting said shutter with a reel mounted on a manually-actuated shaft and connected thereto by a manually-releasable clutch which is normally held in engagement by yielding pressure and a pawl for preventing backward movement of said shaft, for the purposes set forth.

5. In a shutter-operating device, the combination, with a shutter-blind hinged with locking-hinges, of a lever J pivoted to said shutterblind and fulcrumed to a hook or stop J, fixed to the window-casing, and a rope connected with said lever and extended through said hinged shutter-blind, for the purposes stated.

6. In a shutteroperating device, a reel mechanism comprising a frame N, a crankshaft M, mounted in bearings in the frame N and having a fixed pin P, a reel L, mounted loosely on the crank-shaft M and having projections O to be engaged by the pin P, a sleeve S, mounted loosely on the crank-shaft M and having slots on its inner end to admit the pin P and a ratchet-wheel S on its outer end, a pawl V to engage the ratchet-wheel S and a rope J wound on the reel L, for the purposes stated.
