SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 301,899, daten July 15, 1884.

Application tiled November 14, 1883. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM KAUEMAN,

v and ABRAHAM KAUEMAN, of the city, county,

and State of New York, have invented a new and useful Improvement in Shutter-Adjust-v ers and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making apart of this specification.

Our invention relates to an improved shutter-adj uster, and vhas for its object the provision of a simple and easily-applied mechanismV for operating the outside hinged shutter of a window to open or close the same without raising the sash.l

It consists of a horizontal swinging arm, pivoted at one end to the sill of the windowi'rame, and connected at the other by a sliding attachment to a horizontal guide or traveler .bar fixed upon the shutter, this swinging arm being operated to open and close the shutter by means of a toothed segment or cogged wheel formed upon its pivoted end concentric with its pivot-bearing, to engage a toothed rack upon a sliding bar, which, projecting through the casing of the window beneath the closed sash, terminates at its inner endV in a knob or handle, to facilitate its being-moved in or out to operate the swinging arm.

In the accompanying drawings, Figure 1 is a perspective view of a portion of av windowframe and its hinged shutter fitted with our improved shutter-adjuster; and Fig. 2 4is a transverse section through the-window-frame above the sill, illustrating the several parts of the device and their loperation.

A is a shutter hinged in the usual manner to the frame B. Upon the sill of the frame, and within the clear space between the shutter when closed and the lower sash, is pivoted the swinging arm` G, adapted to swing in a horizontal plane and in the same angle rela- -tively to the face of the building as the shutter which it is intended to operate.

D is a traveler or guide-rod secured upon move. The ends of the rod'are bent at right angles to the length thereof, and terminate in plates D D, by means whereof the rod is securely attached to the shutter with woodscrews d d. A portion, C', of the length of the swinging arm at its outer end is bent at right angles to the bodythereof and toward the shutter, and is slotted horizontally to embrace the guide-rod D, to which it is confined by means of a transverse pin, o, at the outer end of the slot. The inner end of the arm C is pivoted to the sill of the window by means of a pivot-pin, G2, and is formed or iitted with a toothed segment or segmental rack, C3, having the pivotal bearing of the arm as its axis. The pivot-pin C2 projects upward from a plate, E, adapted toxbe attachedV to the sill of the window-frame by means of screws, and which is preferably -m'ade long enough to extend inwardly from the pivot-pin CZ-to the inner-face of the window-casing.. Upon its inner end is formed or fitted a perforated block, E', adapted to serve as a guide for a bar, F, fitted to slide with a free longitudinal movement upon the plate E, andv to extend through the guide-block E. The inner end of the bar F is toothed to engage the toothed segment C3, and is kept in contact therewith by means of a lateral iiange, f formed along the edge of the plate E. The end of the bar F projecting through the guideblock terminates in a handle, F2, to facilitate its movement. The block E is iittedV with a clamp-screw, G, adapted, when screwed down, to bear upon and lock the bar F and firmly clamp it, and thus prevent a movement of they swinging arm C.

In the operation of our improved shutteradjuster, the movement in or out of the bai' F will, by means of the rack and toothed segment C3, operate the arm C, and. cause it to swing outward or inward upon its pivot-pin Cz. The outer end of the arm C, traveling in its vibration along the rod D upon the shutter, will carry with it the shutter A, (see dotted lines in Fig. 2,) and the bar F and arm C, and with it the shutter A may be iixed and i locked by means of the clamp-screw G at any desiredl point in its movement.

We claim as our inventiony 1. A shutter-adj uster consisting of a pivotal substantially in the manner and for the pur- Rose herein set forth.

In testimony whereof we have signed our naines to this specification in the presence of 15 two subscribing witnesses.
