PATENT FFICEe- LEON ARD F. NORRIS, OF BROGKTON, MASSACHUSETTS.

SHUTTER-WORKER.

SPECIFICATION forming part'of Letters Patent No. 425,450, dated April 15, 1890.

Application filed June 22,1889, Serial No. 315,219. (No model.)

To all whom it may concern;

Be it known that I, LEGNARD- F. NORRIS, of Brockton, in the county of Plymouth and Commonwealth of Massachusetts, have invented a new and useful Improvement in Shutter-Vorkers, of which the following is a specification, reference being had to the accompanying drawings, which form a part hereof.

My invention relates to a shutter-worker having a shaft which passes through the window-frame and is connected at its outer end with a device for turning the shutter on its hinges when the shaft is revolved, the shaft being operated from within.

My invention consists of a shaft passing through the window-frame and having upon its outer end a sector gear-wheel which meshes with a sector gear-wheel attached to the shutter, the shaft having its bearing in a box which extends beyond the face of the frame and being operated by a crank working through aslot in the box; also, in combining with the handle locking devices to hold the shutter in the position to which it may be set.

In the drawings, Figure l is a front elevation with the blind closed and 1ocked,looking from the outside. Fig. 2 is an edge elevation of the sash and blind with the blind closed. Fig. 3 is a vertical section through the sash with the blind open. Fig. 4 is a horizontal section on line fl 4 of Fig. 3 with the blind open. Fig. 5 is a longitudinal section through the operating handle and shaft detached. Fig. (3 is a cross-section on line 6 6 of Fig. 5.

The shutter A is hinged to the window-frame B at top and bottom by hinges a a in usual manner. The horizontal shaft D passes through the frame B, having its bearing in the box E E. The enlarged portion E of the cylinder extends beyond the frame, and is formed with a transverse slot 6, through which passes the shank f of the crank or operating handle F. The shank f is formed with an eye which fits over the end of the shaft D, as shown in Fig. 6. A pin (Z passes through the shaft and lies in a groove across the face of the eye, and the nut 19 on the end of the shaft clamps the eye against the pin in the groove to pre vent the crank from slipping on the shaft. The slot (2 is of sufficient length to allow the instead of the screws on m.'

handle F to revolve in a vertical plane at least a half-circle. A screw-cap c closes the end of the cylinder. On the end of the shaft which extends outside the window-frame is a sector gear-wheel G, clamped to the shaft, so as to revolve with it.

Attached to the edge of the blind A by means of a plate H is a sector gear-wheel H, Whose teeth mesh with those of the sector gear-wheel G, the planes of the two wheels being at a right angle with each other. An armL is at tached to the window-frame, having a downwardly-projecting pin I, which serves as an axis or hinge on which the gear-wheel l-l turns and prevents the wheels from being thrown out of gear. When the window-fra1ne is flush with the outside wall of the house, the wheel H is pivoted in the center, as shown in the drawings; but where the windowfra-me is recessed and the shutter has to be thrown out in order to swing back against the wall a curved slot in the wheel furnishes a shifting center for the pin I, allowing the shutter to be swung farther out.

The handle F has a staple f or equivalent device adapted to catch in a groove or notch in the head of a screw on in the side of the casing above the shaft when the shutter is closed and the handle is raised, as shown in Fig. 2. The catch is so adjusted that the handle has to be sprung outward to pass the catch into the groove. The metal shank f gives sufficient spring for this to be done. A similar screw m below the shaft engages the handle when the shutter is open. A grooved plate or other equivalent device may be used One or more slots e in the periphery of the cylinder E are so arranged as to receive the slide-bolt r, carried 011 the side of the shank f, and lock the shutter at different angles of opening, according to the number and arrangement of the slots. A spring 5- gives tension to the bolt 0'.

To open the sh utter when closed and looked, as shown in Fig. 2, the handle is sprung out from engagement with the grooved catch and revolved downward, thus rotating the shaft D and wheel G, whose teeth mesh in those of wheel H, and cause the shutter to open. If desired to hold the shutter partially open, the handle is turned until the bolt r comes against one of the slots 6 in the cylinder, into which the bolt is slid, holding the shutter from further Swinging. If desired to swing the shutter full open, the crank is revolved until it points vertically downward, and the handle is sprung into engagement with the groove in screw 0%, as shown in Fig. 3.

What I claim is- 1. In combination with a window frame and shutter, a shaft passing through the windowframe, having its bearing in a box which projects beyond the frame and operated by a crank working through a transverse slot in the box, the shaft having upon its outer end a gear-wheel which meshes with a gear-Wheel attached to the shutter, substantially as described.

2. In combination with a window frame-and shutter, a shaft passing through the windowframe, having its bearing in a box which projects beyond the frame and operated by a crank working through a transverse slotin the box, the shaft having uponits outer end a gear-wheel which meshes with a gear-wheel attached to the shutter, the latter gear-wheel turning on a hinge attached to the windowframe, and the handle carrying a bolt which is adapted to enter a slot or slots in the periphery of the box to lock the shutter at any angle for which the slot may be arranged, substantially as described.

3. In combination with-a Window frame and shutter, a shaft passing through the windowframe, having its bearing in a box which projects beyond the frame and operated by a crank working through a transverse slot in the box, the shaft having upon its outer end a gear-wheel which meshes with a gear-wheel attached to the shutter, and the handle being provided with locking devices for locking the shutter full or partially open or closed, substantially as described.
