SHUTTER.

SPECIFICATION forming part of Letters Patent No. 380,914, dated April 10, 1888.

Application filed October 24, 1887. Serial No. 253,224. (No model.)

To ctZZ whom it may concern:

Be it known that l, JOHN T. lVIILLER, a citizen of the United States, residing at Thayer, in the county of Neosho and State of Kansas, have invented a new and useful Improvement in Shutters, of which the following is a specification.

My invention relates to an improvement in fire, burglar, and storm-proof shutters or curtains for windows and doors; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective view of a window provided with a shutter embodying my improvements. Fig. 2 is a vertical sectional view of the same, taken on the line 0000 of Fig. 1. Fig. 3 is a horizontal transverse sectional view taken on the line y y of Fig. 1. Fig. 4 is a detail section on the line z z of Fig. 1.

A represents a window-frame, to the outer side of which at opposite edges are secured apair of vertical guide-plates, B,which are provided in their opposing edges with grooves O. The said guide-plates are made of any suitable metal and may be either cast or wrought, and are secured to the frame of the window by being provided at their outer edges with rearward-extending flange-plates D,whicl1 extend rearward on the outer sides of the frame and are secured thereto by screws or bolts E. At the upper side of the frame, on the front side thereof, are secured a pair of brackets, F, in which brackets are journaled the ends of a shaft, G. One end of this shaft is provided with a drum, H, to which is secured and on which is coiled a cord, I. The said cordpasses through an opening, K, in the upper side of the window-frame and hangs downward in the room, and is adapted to be grasped by a person in the building. A weight may be attached to this cord to balance the shutter, if desired.

L represents a shutter or curtain, which is composed ofa number of transverse slats, 'M, made of steel or other suitable material and of suitable length, width, and thickness. The ends of these slats fit in the grooves O in the opposing sides of the guide-plates, and the said slats have their opposing edges hinged together by means of LJ-shaped straps N, which are passed through openings in the upper edge of each slat, and have their arms rigidly secured to opposite sides of the next super-incumbent slat, so as to dispose the slats in thesanie plane, the curtain or shutter being thus made flexible, as will be readily understood. The upper side of the flexible curtain or shutter is connected to the shaft G by means of short chains 0.

1? represents a cap or cover, which is substantially semi-cylindrical in shape, is made of any desired ornamental configuration and of any suitable metal, and has its upper edge connected to the upper side of the frame A by means of hinges B. By this construction the cap or cover is adapted to be turned downward, so as to conceal the shaft, the brackets, and the upper portion of the curtain or shutter from sight, and the said cap or cover is adapted to be turned upward, so as to expose the said shaft, brackets, and the upper portion of the curtain or shutter to View.

The operation of my invention is as follows:

When the curtain or shutter is pulled downward,it is guided and retained in place bythe grooves in the guideplates, and its lower end, when it reaches the bottom of the window or door frame, may be secured in any suitable manner.

I have herein shown a hook connected to the sill of the frame and adapted to engage an eye at the lower end of the shutter or curtain; but I do not limit myself in this particular. As the curtain or shutter is drawn downward, it imparts rotation to the shaft, as will be readily understood, and causes the drum to wind up theoperating-cord. Vhenitisdesiredto raise the curtain or shutter, the operatingcord is grasped and drawn downward, which causes the shaft to rotate in the contrary direction, and thereby raise the shutter or curtain and coil the same upon the shaft, as will be readily understood.

Other suitable means may be employed for rotating the shaft and thereby raising or lowering the curtain or shutter, and I do not therefore limit myself in this particular.

Having thus described my invention, I claim- I 1. The combination of the rotating shaft, the flexible metallic curtain connected thereto and adapted to be coiled thereon, said curtain com- IOO prising the slats arranged in the same plane with their opposing edges in contact, and the ,U shaped straps engaging openings in the upper edge of each slat and having their arms secured to opposite sides of each superincumbent slat, and the guides to retain and direct the edges of the said metallic flexible curtain or shutter, substantially as described.

2. The guide-plates B, having the grooves G on their inner edges, for the purpose set forth, and provided with the flan ge-plates D at their outer edges, adapted to bear against the outer sides of the door or window frame, substantially as described.

3. The combination of the frame having the brackets at its upper side, the'shaft journaled in the said brackets, the flexible metallic curtain or shutter having its upper edge connected to the shaft and adapted to be coiled thereon, and the cap or cover hinged at the 20 upper inner corner to the frame and adapted to be folded downward over the shaft and the bracket to conceal the same from view, substantially as described.

In testimony that I claim the foregoing as my 25 own I have hereto affixed my signature in presence of two witnesses.

JOHN T. MILLER,
