THOMAS N. LUPTON, OF IVINCHESTER, VIRGINIA.

SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 503,866, dated August 22, 1893.

Application tiled November 16, 1892. Serial No. 452,213. (No model.)

' To aZZ whom it may concern:

Be it known that I, THOMAS N. LUPToN, residing at VIinchester, in the county of Frederick and State of Virginia, have invented a new and useful Improvement in Shutter- Workers, of which the following is a specification. v

This invention is an improvement in shutter workers and has for an obj ect to provide a novel, simple and Vcompact construction whereby the shutter maybe opened or closed from within the room and be locked and unlocked in both its open and closed positions without requiring the window to be opened, and the invention consists in certain features of construction and novel combinations of parts as will be hereinafter described and pointed out in the claims.

In the drawings-Figur'el is a perspective view of my improvement. Fig. 2 is a vertical section. Figs. 3 and are horizontal sections. Figs. 5 and 6 show different forms of connections between the sections, and Fig. 7 is a detail perspective view of the hinge.

The shutter A, which may be of ordinary construction is suitably hinged to open and close, one hinge A being of ordinary construction and the other hinge B being also of ordinary construction except in the respects hereinafter described.

In connection with the swinging leaf b, of the hinge B, I provide the roller or shaft C, having upper and lower roller surfaces C and C. These rollers C C2 are preferably grooved to better secure the operating chains, wires or bands to them, but manifestly these grooves may be omitted when the wire cables presently described are used. The roller or shaft C is arrangedin alignment with the pintle or center of movement of the hinge, so that the turning of the roller or shaft will operate to turn the swinging leaf of the hinge and so open or close the shutter according to the direction of movement given to the shaft O. A horizontal shaft D is arranged transversely of the roller C and has at its opposite ends r'oller surfaces D and D2 which are preferably grooved similarly to the corresponding parts of the shaft C and these end rollers D and D2 bear such relation to the rollers C and C2 that the cables or connections may pass from the upper side of one of them to the upper rollerof shaft C and from the lower side ofthe other one to the lower roller of said shaft. The said connections E and F are secured at one end to the rollers of one shaft and at their outer ends to the rollers of the other shaft and wind in reverse directions on the opposite rollers of the shafts C and D so that the turning of the shaft D in one direction will operate to positively open' the shutter and in the other direction to positively close the same.

In order to arrange the rollers C and D in close relation it is greatly preferred to form the shafts both with reduced portions between their end rollers and to t the reduced portion Vof one to that of the other so that they will occupy but a small space. This is desirable because it enables both the rollers to be arranged within the space around which the inner edge of the shutter swings and permits a casing G to be fitted over said shafts without forming any unsightly obstruction on the face of the building.

The connections E and F may be of wire cable as preferred or of chains, strips of tempered steel or other metal, leather, raw hide', or other suitable material as desired.

To operate the shaft D I provide a shaft H extended through the window frame having a handle H within the room and preferably made separate from and fitted at its outer angular end in a socket in the shaftD as will be understood from the drawings.

The operation will be readily understood. The shaft D may be turned to easily open or close the shutter. Vhen open the shutter -may be secured by its catch I engaging with the latch J. This latch J is L-shaped having one wing J arranged to secure latch I and its'other wing J2 pivoted at J3 to the fixed leaf of the lower hinge and extended inward beyond its pivot .I 3 forming a crank like extension .I4 which may be engaged by a slide rod J5 leading from within the room and by which the gravity latch .I may be conveniently operated to release the catch I when it is desired to close the shutter.

To lock the shutter closed I provide on its inner face a catch K, which engages a gravity latch L having a hinged plate L', such plate being provided with a crank like stem L2 for engagement by a push rod L3. from roller C also forms a part of such completed Vhinge which may be manufactured and sold` ready for appli cation. The catches I a'ndl have their shanks Z formed to taper toward their extremities so that they may be tight-l cned in place by'dravving. them inward '"by-a""` fastening nut or by driving them' into the- Wood of the shutter as may be preferred.

f ter off, it -isonly necessary to withdraw the shaft- H from the -shaft-D,When the shutter may be lifted olf as usual.
