Aren't ALVIN H. DODD, OF HUDSON, NEW YORK.

SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 316,131, dated April 21, 1835.

Application filed December 29, 1884. (X0 model.)

To (ZZZ whom it mayc0ncern:

Be it known that I, ALVIN H. DODD, of Hudson, in the county of Columbia and State of New York, have invented a new and useful Improvement in Shutter-Workers, of which the following is a'specificatiou,

My invention relates to those shutter-workers in which one member or leaf of the'blind or shutter hinge has formedmpon or connected with it a toothed segment or wheel, and the other member or leafhasjournaled in it a worm or screw which engages with the toothed segment, and has a shaft which extends to the inside of the window,and may be there operated by a crank or handle. The operation of the crank or handle turns the worm or screw, and the latter by its engagement with the toothed segment or wheel, opens and closes the blind or shutter and holdsit in any position to which it is adjusted.

My invention consistsin novel details of construction and combinations of parts in a shutter-worker of the kind above described,whereby its construction is oh eapened, and it is rendered more easy of application to various window frames, casings, and shutters or blinds, in connection with which it is desired to use such a shutter-worker. These features of novelty are hereinafter particularly described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a horizontal section of a portion of a windowcasing and frame and a shutter, showing my improved shutter worker applied thereto. Fig. 2 is an inverted plan of the parts of the worker; and Fig. 3 is a vertical section of the parts of the worker on the plane of the dotted line :0 as, Fig. 1.

Similar letters of reference designate corresponding parts in all the figures.

A designates the shutter or blind. B designates the Window frame and casing, which is constructed with the usual weight-box, B,and G is the sash. All these parts are of ordinary construction, and G O are the weights which are applied to the lower sash, O, and the upper sash, not here shown.

D D designate the members or leaves of the hinge, the former, D, being secured to the shutter A, and the latter, D, to the window-frame B. These leaves have bearers d d, which are connected bya pivot or pintle, e. The bearer (1,011 the member orleaf D, is cast with a gear or worm segment or wheel, 01*, upon it, andin the member or leafD isjournaled aworm or screw, E, which engages with the gear or worm segment or wheel (1*. The worm or screw E has a stem orjournal, E, which is fitted to a bearing in a hub, (1 projecting outward from the leaf or member D, thereby leaving the inner side or face of the saidleaf or member flat, and requiring no cutting away of the frame. As most clearly shown in Fig. 2, the hub d is connected with the bearer d 'bya brace or web, (1", formedintegral with them in casting, and both thehub or bearing d and the bearer d are thereby strengthened. The worm or screw E should have at least three threads to the inch,

because if it has less the angle of obliquity of the threads will be such that the shutter may be turned by force applied'directly to it, and hence may be opened by any one outside the building. The worm or screw E and its stem or journal E may be made in one piece, either by casting or as a drop-forging.

E designates the worm or screw shaft, which extends to theinner side of the window casing and frame B. This must obviously be of a length adapted to the depth of the casing and frame, and hence ashaft of definite length cannot be provided for all situations. To provide for this I make the shaft E of a separate rod joined to the worm-stem or journal E by a sleeve, E As shown in Figs. 1 and 3, the stem E and shaft E enter opposite ends of the sleeve E and are held therein by pins 9 inserted through them, or in any other suitable way. This sleeve E may be of cast metal.

F designates a flanged bearing, in which the inner end of the shaft E is journaled,and which may be secured to the inner side of the frame and casing 13 by screws or other means. To the inner end of the shaft E adjacent to the bearing F, is secured or may be applied a handle or crank, G, for turning the shaft and worm to open and close the shutter or blind.

I am aware that it is not new to employ in connection with the two leaves of a shutterhinge a toothed segment on one hinge-bearer, and a worm or screw journaled in the other leaf, and a shaft for turning the worm or screw extending inward to the inner side of the window-casing, and there provided with a crank. Hence I do not claim, broadly, such a shutterworker as of my invention, and only seek to include those features of construction and combinations of parts which are hereinabove described, and which enable me to produce a very cheap and simple device, which may be applied to window-casings of different depths or thicknesses, and which will not require cutting away or recessing the casing.

The construction of the leaf D with a flat inner side and an outwardly-projecting hub, d and the combination therewith' of a worm extending outside of and beyond the hub, and having a stem journaled in the hub and projecting inward of the inner face of the leaf, enables me to apply the leaf to the casing without any cutting away thereof, and to employ the shortest possiblelength of worm, and still have an adequate bearing in the leaf.

The construction of the worm with its stem and the crank separate from the shaft E and the connection of the shaft and stem by a sleey e and pins, enables me to employ for the shaft 9. heavy wire or light iron rod of any suitable length adapted to the thickness of the windowcasing.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination,with the hinge composed of two leaves, D D, with their bearers, one of said bearers having the toothed segment d*,of

the worm E, projecting outside of and beyond the leaf D,and its stem E, projecting inward, through, and beyond said leaf, and having a bearing therein, the shaft E made separate from the worm and its stem, and the sleeve E made separate from the shaft and worm-stem, and connecting them together, substantially as herein described.

2. The combination,with the leaf D,with its bearer d and toothed segment (1*, of the leaf D, with its bearer d and outwardly-projecting hub d the worm E, outside the said hub, and its stem E, journaled in said hub, and projecting inward beyond the inner face of the leaf D, the operating-shaft E and the separate sleeve and pins E g, for connecting said shaft and the stem E, the bearing F, for the inner end of the shaft E", and the crank or han dle G, made separate from the shaft and secured thereto inside the bearing F, all substantially as herein described.
