SLAT-OPERATOR FOIR SHUTTERS.

SPECIFICATION forming part of Letters Patent No. 546,845, dated September 24, 1895.

Application led February 9, 1895. Serial No. 537,731. (No model.) I

To all whom t may concern.'

Be it known that I, THnoDoRn M. FULLER, a citizen ofthe United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Slat-Operators for Shutters, of which the following is a specification.

The object of my invention is to provide a simple and cheap device by which the slats of shutters can be turned to any desired angle and locked or fastened in position, which device can be applied to shutters of various sizes within reasonable limits, so that if the vertical side bars of a shutter should be somewhat wider apart than the length of the slats to be attached the said device will provide for the difference in size between said parts.

In carrying out -my invention I provide channeled metal plates, which are placed parallel to the vertical side bars of the shutter and at such a distance from the inner surfaces of said side bars as to form a space between said plates and said bars.

The accompanying drawings form part of this specification and represent what I consider the best means of carrying out the invention.

Figure lis a face view of a shutter provided with my improvements, showing the slats in the closed position. Fig. 2 is a corresponding view showing the slats in the open position. Fig. 3 is a perspective view of the plate provided with the curved slots, which is fastened to one of the vertical sides of the shutter. Fig. 4t is a face view of said plate, looking in the direction of the arrow l in Fig. l, showing in dotted lines the slats in the closed position, and thereby illustrating the dilferent relations of the parts. Fig. 5 is a face view of the pivotplate at the opposite side of the shutter, locking in the direction of the arrow 2 in Fig. 1. Fig. 6 is a detail face view of the sliding plate having the oblique or inclined slots. Fig. 7 is a perspective view ofthe plate shown in Fig. 5, looking at its interior; and Fig. 8 is a perspective view of the sliding plate. Figs. 4, 5, 6, 7, and 8 are taken on an enlarged scale.

In the accompanying drawings, in which similar letters of reference indicate corresponding parts in the several views, the letter ,/.Andicates the frame of a shutter, which may be of any suitable construction, having the vertical side bars A and A2, and B are the slats pivotally carried between said side bars A A2.

C is a plate adapted to lie parallel with the side bar A and may be suitably secured thereto, so as to leave a space between said side bar and said plate. The plate C is channeled-that is to say, provided with two side webs c, which extend substantially at right angles to the main portion of the plate, whereby the space between said plate and the side bar A is covered. The sides c of the plate C are shown provided with lugs c2, having apertures c3 to receive screws 04, by which the plate C can be secured to the shutter. By this means also the plate C can be adjusted at a greater or less distance from the vertical side bar A in order to provide for different lengths of slats B when necessary.

The plate C has a series of apertures c5, adapted to receive pivots Z2, carried by the slats B. The pivots Z) are placed near one edge of the slats B, whereby said slats are eccentrically pivoted in contradistinction to the usual concentric pivots for the slats of shutters.

The plate C is provided with a series of curved slots D, the curve of the slot D being derived around the apertures c5 as a center, there being one slot D for each pivot b.

ol are pins carried by the slats B and passing into the corresponding curved slots D of the plate C, whereby said pins are allowed to travel in the plate C when the slats are turned, the metal at the ends of the slots D serving to limit the motion of the pins d. When these pins d are raised or lowered, they will move the slats B correspondingly, the latter turning on their pivots b.

E is a sliding plate or bar located in the space between the vertical barA of the shutter A and the plate C. The plate E is adapted to have a sliding movement in the said space, and said plate is provided with oblique or inclined slots e, receiving the pins al of the slats B. The slots e extend across the slots D of the plate C substantially at right angles thereto, as shown in Fig. e. When the plate E is raised or lowered, its oblique or inclined slots e will act upon the pins CZ of the slats B, and thereby cause said slats to turn on their pivots b, and the pins d thereupon traverse their respective slots D of the plate C. By this means the slats B can be turned more or less, as desired, to open or close them, as the case may be.

It is designed that the sliding plate E can be held in any desired position, and for this purpose I have shown said plate as provided with a stud F, screw-threaded to receive a thumb-nut G, the sides c of the plate C having a slotf, through which the stud F passes, and in which slot it travels. The thumb-nut G is adapted to press against the side c of the plate C when screwed down, and by this means serves to hold the sliding plate E locked in any desired position; but of course other suitable means may be provided for operating the plate E and for holding it in any desired position.

The vertical bar A2 of the shutter A is also provided with a channeled plate C2, corresponding to the plate C and having similar apertured lugs c2 for connection with the bar A2 ofthe shutter. The plate C2 is also provided with a series of apertures c5 c to receive pivot-pins b2 at the ends of the slats B opposite to the pins b, the pins b2 being in line with the pins b. The plate C2 can be adjusted toward or from the side bar A2 of the shutter, in accordance with the length of the slats to be used.

By preference the pivots l) b2 `and the operating-pins d of the slats B will be made separate from the slats (such as metal pins) and driven into the slats at the desired points, by which means I am enabled to save the cost o1' forming the pivots for the slats from the material ofthe slats, as is customary with the slats of ordinary shutters. The parts C, C2,

and E may be made of tinned iron or other suitable sheet metal of proper thickness and can be applied to shutters already in use, or can be made directly with the shutters in their manufacture. The parts are so simple and so readily adjusted that almost any one can apply them to a shutter without the necessity ot' calling upon a skilled mechanic for that purpose. By setting the pivots b ou which the slats turn near one edge of their respective slats the pins d may be at a greater distance therefrom, and thus a greater' leverage can beobtained, the friction due to the traverse of the several pins d in the oblique slots e being usually suiiicient to hold the Whole against gravity and Wind and the clamping-arms F G being available to additionally secure them when required,

I do not limit my invention to the precise details of construction shown and described, as they may be varied without departing from the spirit of my invention.

Having now described my inventiomwhat I claim is The combination with a shutter frame and the slats thereof, oi' a pivot plate interposed between the side bar of the frame and the slats and provided with pivot holes for said slats, a slat operating bar between the plate and. side bar, and webs extending from the pivot plate, covering said operating device, and overlapping the side bar, whereby said plate may be adjustably secured to said side bar at variable distances therefrom, substantially as described.

In testimony that I claim the invention above set forth I afiix my signature in presence ot two witnesses.
