f Application filed July 30.1907. Serial No. 386.286.

To all whom it may concern.'

Be it known that I, BERTRAND E. BEYER, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Shutter-B owers; and I do hereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention relates to an adjusting device to be attached to blinds, shutters, doors and similar structures, and is designed to hold the swinging member, for instance a shutter, at any 'point in its radius of movement, and to securely lock it in the position in which it has been adjusted.

The invention provides an article of this kind embodying a slide-piece that is adapted to lock the shutter, the slide-piece having ngers which provide for its manipulation, whereby the shutter is opened by means of the adjuster, and one hand can be used for the whole operation, this handle providing also for releasing the locking means when it is grasped for its mani ulation. In this way the releasing and the ocking are coincident with the respective grasping and letting go of the finger-piece by the person operating the device.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a perspective view of the device mounted on a window casing and shutter. Fig. 2 is a section of the slide-piece and locking mechanism. Fig. 3 is a section of the window frame, but showing the shutter and the adjusting mechanism in elevation, and illustrating the shutter in its open position by a dotted outline.-

I secure to the window casing or frame 10, the standard 11, securing it preferably by means of the screws 12, and on this standard is pivoted an arm 13 which swings when the shutter is opened or closed, the other end of the arm 13 being pivoted between the ears 14 of the slide-piece 15. The slide-piece is hollow and has perforations 16 through which passes the rod 17. The rod 17 is secured, on its two ends by means of the plates 1S and the screws 19, to the shutter 20.

This vstructure allows the slide-piece to travel along the rod 17, and the shutter can be swung open to its full extent, as shown in Fig. 3, in which position the slide-piece 15 is on the end-of the rod nearest the hinge 21. One wall of the slide-piece 15 has the perforations 22 through which project the iinger-pieces 23, the inner ends 24 of the iingerpieces being perforated, the perforations allowing the passage of the rod 17. The finger pieces are thus fulcrumed, intermediate of their ends, in the perforations 22, and are normally pushed toward one another by means of the springs 25. The inner ends 24 of the finger-pieces are thus inclined at an angle to the rod 17, and are thereby made to bite the rod 17 at any point where -the iinger-pieces are released.

When the iinger-pieces 23 are grasped between the thumb and forefinger of the operators hand, the inner ends 24 of the iingerpieces are forced against the action of the springs. 25, and the. perforations in the ends 24 are 1n line, or approximately so, and they thus offer no resistance to the slide-piece traveling on the rod 17, and by sliding the slide-piece, by means of the finger-pieces along the rod, the shutter is operated, and when there are two shutters to a window they can be opened simultaneously, one hand being used on the iinger-pieces of each shutter. Whenever the shutter is in the position it is desired to have it, the operator simply releases the iinger-pieces, the springs 25 force the inner ends of the iinger-pieces so that they bind on the rod, and the shutter is held against any movement. The standard 11 is so disposed that the arm 13 will not interfere with the hinge of the shutter, when the shutter is thrown open as indicated in the dotted outline in Fig. 3.

If desired, I can replace the two compression springs 25, shown in Fig. '2, by any other usual style of spring that will bring about the binding of the ends 24 of the fingerieces on the rod 17.

T e articular shapes and outline of the respectlve parts of this invention can be altered to suit the style of house or building on which it is to be used.

Having thus described my invention, what I claim is:q

In combination with a casing having a swinging member, of a standard secured to the casing, an arm having one end secured to the standard and arranged to L swing inner ends of the finger-pieces in engage- 1 thereon, a sliding member pivotally secured ment with the rod to lock the same.

to the projecting end of the arm, a rod se- In testimony that I claim the foregoing, cured to the swing g member, the sliding I have hereunto set my hand this 27th day member being mounted on the rod, `a pair of July 1907.
