SHUTTER-WORKER.

Specification of Letters Patent.

Patented Feb. 4, 1908.

Application filed November 8, 1907; Serial No. 401.267.

To all whom it may concern:

Be it known that I, WILLIAM J. AUMEN, citizen of the United States, residing at Allentown, in the county of Lehigh and State of Pennsylvania, have invented new and useful Improvements in Shutter-Workers, of which the following is a specification.

My invention pertains to shutter-workers, and consists in the peculiar and advantageous means, hereinafter described and specifically claimed, for adjustably fixing the mechanism through the medium of which a shutter is Worked.

In the drawings accompanying and forming part of this specification: Figure 1 is an elevation of shutters equipped with my improvements one of the shutters being shown open and the other closed. Fig. 2 is a vertical section taken in a plane at the right of the open shutter and. looking toward the same. Fig. 3 is an enlarged detail horizontal section taken through the closed shutter in a plane above the gearing complementary thereto, and: Fig. 4 is an enlarged detail elevation of that portionof my improvements located on the inner side of one of the side stiles of the window frame. 7

Similar letters designate corresponding arts in all of the views of the drawings, referring to which:

A is the window frame. B B are sashes slidable therein, and C C are the shutters which are hinged adjacent to their upper ends at a in the ordinary well known manner or in any other manner compatible with the purpose of my invention.

The mode of hinging the lower portions of the shutters C is similar with reference to both shutters, and the mechanisms for working the two shutters are identical, and for these reasons a detailed description of the manner in which the shutter shown in Figs. 2 and 3 is hinged at its lower end and worked will suflice to impart a definite understand ing of my improvements as applied to the two shutters. The said shutter of Figs. 2 and 3 is suitably fixed to a hinged member D, and this hinged member, in turn, is fixed to the upper end of a pintle E which is journaled in a hinge member F fixed to one side stile of the frame A and is provided at its lower end with" a gear G, preferably a mutilated beveled gear, such as shown in Fig. 3.

Extending through and journaled in suit- :said positions,

able bearings in the side stile of the window frame is a shaft H which is provided at its outer end with a gear I intermeshed with the gear G, and, at its inner end, is equipped with a toothed wheel J and a handle K; the latter being in the form of a T-head as clearly shown in Fig. 4. 1:

Connected at its upper end to the inner side of the side stile of the frame A is a spring locking strip the lower end of which tends to assume and rest in the same plane as the toothed wheel J and in one of the interdental spaces of the said Wheel. By virtue of this it is evident that the said strip which is let- .tered M will serve to lock the shaft H against rotation and the shutter connected with said shaft against swinging; and it is also evident that when the lower, free end of the strip M is pressed toward the face of the stile and out of engagement with the wheel J, the shaft I-I may be readily turned through power applied to the handle K to either open or close the shutter.

By'reference to Fig. 2 it will be understood that when the spring strip M is pressed out of engagement with the wheel J, the shutter may, by the operator turning the handle K, be opened or closed to a greater or less extent, and when said shutter is either opened or closed or is at a point intermediate it may be securely locked by the operator simply releasing the strip M, for when this is done the said strip M will immediately assume a position in one of the interdental s aces of the wheel J.

It will be gathered from the foregoing that the spring locking strips M are simple and inexpensive in construction, are reliable in operation and are adapted to be quickly and easily manipulated to release the shutterworking mechanism; also, that when pressure is removed from said strips M the same positively spring into position to engage the toothed wheels J.

Having described my invention, what I claim and desire to secure by Letters-Patent is:

The combination with a window frame, a shutter hinged thereto, a shaft j ournaled in the frame and extending from the inner side to the outer side thereof, gearing connecting said shaft with the shutter, a toothed wheel fixed on the portion of the shaft at the inner side of the frame, and a handle also fixed on said portion of the shaft of a spring strip In testimony whereof I have hereunto set fixed to the inner side of the frame and havmy hand in presence of two subscribing wit ing a free end normally arranged in one of nesses.

the intermediate spaces of the toothed wheel i WILLIAM J. AUMEN. Y 1 i 5 and also arranged to be sprung toward the l/Vitnesses:
