SPECIFICATION forming part of Letters Patent No.' 292,225, datedJanuary 52, 1884,

v Application filed Novembcrl2-l,1883. (Nomodel.)

To all whom, 4it may concern,.-

Be it known that I, WILLIAM HAWN, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented certain new and useful Improvements in Shutter-VVorkers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a partv of this specification, and to the letters and gures 'of reference marked thereon.

. Figure 1 of the drawings represents a portion of a window-frame in cross-section with my invention applied; Fig. 2, a vertical section through line x x, Fig. l; Fig. 3, a per-- spective view in detail ofthe slide-bolt and outside shell or casing cover in an inverted position; and Fig. 4 a similar view ofthe shutter-connection.

This invention relates to certain new and useful improvements in shutter-workers, and has for its object to improve the construction of this class of devices, so as to do away Awith the usually-employed rods or bars projecting either in or outside from a building, and at the same time provide such a device simple and durable in its construction, easy of opertion, inaccessible Vto burglars, and its mechanism so shielded as to prevent its being tampered with or designedly broken, at the same time admitting of the shutter being locked in an opened, closed, or intermediate position, thereby preventing it from slamming orrat- Ifling. The device being operated entirely from the inside` of a building, the raising of windows in cold or stormy weather is avoided, and the usual lower hinge for the shutter is dispensed with, as said device and its shutterconnection takes the place and performs the function of such a hinge.

The invention therefore consists in the general construction and arrangement of the several operative parts, as will be hereinafter more fully described with reference to the accompanying drawings.

In the drawings, A represents a suitable shell or casing adapted to be secured to the outside of a window-frame, B, and has journaled therein a pulley, C, preferably cast with its axle in one piece, said axle being extended and squared at its upper end, as shown at a,

l for the purpose hereinafter described. The

upper rim of this pulley C is provided with a series of slots adapted to receivea slide-bolt, D, and are arranged at such intervals as to come in line with said bolt when the shutter is moved in certain positions, said shutter having secured thereto a connection, E, (shown inv detail by Fig. 4,) which, with the pulley, takes the place and performs the function of the usual lower hinge, said connection, acting as the upper leaf or wing to such hinge, terminates in a socket, b, which fits upon the squared end a of the pulley7 s axle. The slidebolt D is provided with a slot, c, atv its outer end, and is 'secured to the under side of a removable cover, F, for the shell or casing A, by means of a binding-screw, d, passing through said slot and entering the shell or casings cover. The inner or free end. of this slidebolt terminates in a handle or knob, e, and passes Vthrough a shell or casing, G, adapted to be secured upon the inner side ofthe win` -I -dow-fra'me B. This shell or casing GrV has journaled therein a pulley, H, having the upper end of its axle adapted to extend above the top of said shell or casing and connect with a crank or hand-lever, I, as shown at f, Fig. 2, a spring or other suitable stop being interposed between the upper face of the pulley and the top of its shell or casing to prevent said pulley having too much play or becoming displaced.

In the application of my invention, the pul-1 ley C, having thereon -a suitable band, K, is placed in its shell or casing A, and the cover F, having secured to its under side the slide-bolt D, is then put on and, with the band, is passed through an aperture made in the window-frame B, the shell or casing being secured upon the outside. The inside shell or casing, G, and pulley H having been adjusted and secured in position uponA the interior of the Window frame, the-band Kv is fastened around said pulley, ,and the several parts are thus ready for operation, the sliding bolt being in engagement with one of the notches in the upper rim of the pulley C, as shown by Fig. 1, and the crank or hand-lever I in the position indicated by dotted lines. The socket b of the connection E, secured to the shutter L, is now en- IOO gagedwith the vsquared end a of the axle of outside pulley, C, so as to bring said shutter in its closed position or on a line parallel with the position of the crank or hand-lever I. Vhen it is desired to open the shutter, the slide-bolt is drawn out of engagement with the notch in the rim of pulley C and the lever I op` erated in the direction of arrow, thus imparting motion to the pulley H, and that, through the inediuln of the band II, to the pulley C, which, with the connection E, forms the lower hinge for said shutter, and by its partial revolution causes the same to open, and when thus opened is locked in such position by the slide-bolt being pushed up to engage with the notches in the rim of said pulley C, though, if desired, a suitable spring may be employed to automatically operate this bolt. Then the shutter is entirely opened, the pulley C will have made one-halfa revolution, and any intermediate opening inay be obtained by having the notches in the rim ot' said pulley arranged to correspond, and when either opened or closed the shutter is securely locked in such position and cannot be blown to or tampered with from the outside; and as the same is operated entirely from the inside, the necessity of raising the window is obviated, while the several operative parts are entirely protected from the weather, and will last for an indefinite period of time; also, the mechanism is kept clean and free from dust, rendering the device less liable to get out of order.

Though I have described the inehanisni for operating the shutter as consisting, principally, of a band and pulleys, a sprocket mechanism may be as readily employed.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

An interior pulley or sprocket-wheel arranged within a shell or casing and kept in position by a spring or stop, and provided with a crank or lever, in combination with an eXterior pulley or sprocket-wheel similarly arranged and provided with an extended axle and notched rim, said pulleys being connected by asuitable band, a slotted sliding bolt provided at its inner end with a handle or knob, and se cured at its outer end to the under side ofthe cover of the exterior shell or casing, and a suitable socketed connecting device adapted to be secured to a shutter, all arranged to operate substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
