WINDOW-SHUTTER-OPERATING DEVICE.

Specification of Letters Patent.

Patented June 11, 1907.

Application filed January 27,1906. Serial No. 298,264.

To all whom, it may concern.-

Be it known that I, HARRY N. LOWEN- THAL, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Vindow-Shutter-Operating Devices, of which the following is a specification.

My invention relates to that class of window shutter operating devices which permit of the manipulation of the shutters from the inner side of the house, in order that the shutters may be opened or closed without raising the sash, the object of my invention being to provide a simple and effective device of this class which will permit of the ready moving of either shutter from a fully opened to a fully closed position, or to any desired inter mediate position will serve to lock the shutter ineither position of adjustment, and will not expose to an objectionable extent on the inside of the window frame the mechanism whereby the movements of the shutters are effected.

In the accompanying drawing Figure 1, is a sectional plan view on the line a-a, Fig. 2, of so much of a window frame, a pair of shutters and operating mechanism for the latter, as is necessary to illustrate my present invention, and Fig. 2, is a view, partly in side elevation and partly in transverse section, on the line l)b, Fig. 1.

1 represents part of a window frame, 2 part of the lower sash, and 3-3 the window shutters which are hung to the side portions of the frame in the usual manner.

In the sill portion of the frame 1 are formed horizontal slots 4, one for each shutter, each of these slots being open at the outer face of the sill and having at one of its inner corners a chamber 5, which is normally closed at the top by the movable cap plate or facing 6 of the sill, as shown in Fig. 2.

To the base of the chamber 5 is secured a plate 7, having a central upwardly projecting pin 8 and a series of openings 9 equidistant from said pin, the latter serving as a pivot post for a lever 10, which is free to swing in the slot 4, and has a hub 1 1 with upwardly projecting stem 12, said stem passing through an opening in the facing plate 6 of the sill and through an opening in an escutcheon 13 on said facing plate, and being provided at the top with a suitable knob or handle 14, whereby it can be readily turned. The free end of the lever 1 0 is connected by a link 15 to a bracket 16 on the shutter, and on the underside of the lever, at points equidistant from the hub of the same, are downwardly proj ecting pins 17 which, when said hub portion of the lever is in its lowered position, as shown in Fig. 2, enter diametrically opposite openings 9 in the plate 7, and thus serve to lock the lever 10 against movement in either direction. \Vhen, however, the hub portion of the lever is lifted by means of the knob or handle 14 until these pins 17 are free from engagement with the openings 9 of the baseplate, the lever 10 can be freelyswung in either direction by turning said knob or handle so as to open or close the shutter.

At the left hand side of Fig. 1, a shutter is shown in the fully opened position, and at the right hand side of said figure a shutter is shown in the fully closed position, the shutter being locked in either of these positions by engagement of the pins 17 with the openings 9 in the base-plate, and being also susceptible of being locked in either one of a number of intermediate positions, depending upon the number of openings 9 with which said base-plate is provided.

As the stem 12, with its knob or handle 14, are the only portions of the mechanism exposed on the inner side of the sill the device is not objectionable in this respect.

I claim 1 The combination of a window frame, hav ing a window a shutter, and a sill, said sill having a horizontally slotted recess open on its outer face and a chamber at one of the innor corners of the recess, opening on the upper surface of said sill inside the window, a cap plate closing the opening of said chamber, a plate secured to the base of the chamber and provided with an upwardly projecting pin and a series of openings concentric therewith, a lever pivotally mounted 011 the pin and vertically movable thereon, a hub for the lever having a stem projecting upwardly through the cap plate, a handle on the upper end of the stern, downwardly proname to this specification, in the presence of jecting pins Oil the lever plllacedhto engage the two subscribing Witnesses. 0 enin s in t e p ate Wit in t e chamber, a bi acke on the shutter, and a link connecting HARRY LOWENTHAL' 5 said bracket With the lever, substantially as WVitnesses:

described. WM. E6 SHU'PE, In testimony whereof, I have signed my Jos. Ii KLEIN.
