JAMES G. WILSON, OF NEW YORK, N. Y.

COMBINED ROLLING AND FOLDING SHUTTER.

SPECIFICATION forming part of Letters Patent No. 663,554, dated December 11, 1900.

Application filed June 13,1900.

To all whom it may concern;

Be it known that 1, JAMES GODFREY WIL- SON, a subject of Victoria, Queen of Great Britain, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in a Combined Rolling and Folding Shutter; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in combined rolling and folding shutters such as are to be used in connection with large windows and doors, and has for its object to improve the appearance of the shutter and to make it stronger, more durable, and quicker in operation and more economical in cost.

With these ends in view my invention consists in the details of construction and combination of parts, such as will hereinafter be fully set forth and then specifically designated by the claims.

In the accompanying drawings, which form a part of this application, Figure l is a front elevation showing my improvedshutter in closed condition. Figs, 2 and 3 are sectional elevations at the line w of Fig. 1 and showing, respectively, the position of the parts of my improvement when the shutter is lowered and raised; Fig. 4, a detailed broken eleva-' tion, on an enlarged scale, showing the two upper leavesin folded condition and the manner of attaching the upper short leaf to the angleiron which is secured to the lower edge of the rolling shutter, and also showing, in side elevation, the trunnion on the lower leaf; and Fig. is a detail broken sectional elevation showing the construction of the shutter and trunnion guides, with the end of one of the shutters in position therein.

Similar numbers of reference denote like parts in the several figures of the drawings.

Prior to my invention the ordinary corrugated iron rolling shutter has been commonly used, and I therefore do not wish to be understood as laying any claim to such construction.

1 is the usual corrugated iron shutter, capafierial No. 20,174. (No model.)

ble of being rolled over the drum 2, secured in position at the top of the door, the ends of said shutter being guided within ways 3 and 9 at the sides of the doorway.

4 is an angle-iron which is secured to the lower edge of the rolling shutter. 5 is a plain leaf-shutter one of whose edges is hinged at 6 to this angle-iron, 7 is also a plain leafshutter which is hinged at one of its edges to the free edge of the leaf 5, and 25 is also a plain leaf shutter one of whose edges is hinged to the free edge of the leaf 7, these points of hinging referred to being so arranged that the leaves will fold in reverse directions, as will be presently explained.

The ways 9 at the sides of the doorway extend upward only a distance substantially equal to the combined widths of the leaves 5, 7, and 8. 10 11 are trunnions which extend axially from the ends of the leaves 7 8 and are preferably provided with friction-rolls 12 13, and 14 15 arecords or cables secured to these trunnions at each side of the leaves and passed upwardly over the grooves of double pulleys 16 17, that are suitably journaled above the doorway and at each side thereof, and to these cords are attached weights 18 19.

The ways 3 and 9 are in vertical alinement and are practically a continuation one of the other; but the ways 9 are a trifle wider and extend inwardly, so as to inclose the ends of the leaves when the latter are in closed position. The trunnions 1O 11 are always within the ways 3, so that it will be readily understood that the shutters will always be guided in a true vertical plane by reason of the fact that they are properly cen tered by these trunnions. The cords'la are secured to the trunnions 10 and are passed up through the ways over one set of grooves in the pulleys 16 17, and from the free ends of these cords the weights l8 depend. The cords 15 are attached to the trunnions 11 and are passed up through the ways overthe other set of grooves in the pulleys 16 17, and from the free ends of these cords depend weights 19.

is an eye which is secured to the lower leaf 8 for convenience in operating the shutter, both in elevating the same and in pulling it down by any suitable means.

The construction, arrangement, and opera- Presupposing the shutter to be in closed I condition, as shown at Fig. 1, if the same is now raised the leaves will maintain their re- 3 lation in the same vertical plane until the lowest leaf has been raised clear of the guideways 9, and then the action of the weights upon the leaves 7 8 will cause the same to rapidly fold up into the position shownat Fig. 3, the trunnions meanwhile preserving their position within the guideways 3. The Ways 9 overlapping, as they do, the shutters at their ends will prevent any folding of the latter on their hinges until the leaves have entirely cleared the ways 9. When it is desired to lower the shutter, any proper hook device is simply engaged with the eye 20, and the leaves are then pulled down in a vertical position and are readily lowered into the position shown at Fig. 1.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. Theherein-describedshuttercomprising the reversely-hinged leaves suspended from an element capable of being raised and lowered said leaves being provided with trunnions suitably guided within ways, the guideways which inclose the side edges of said leaves, and the cords secured to said trunnions and passed over pulleys and having their free ends connected with weights, substantially as set forth.

2. In a shutter, the combination of the reversely-hinged leaves guided and maintained in a vertical plane throughout a predetermined distance, means for elevating and lowering said leaves in a vertical plane, and

weights connected by cords to the ends of said leaves whereby the latter are caused to fold against each other, substantially as set forth.

3. The combination of the corrugated iron shutter capable of being elevated and lowcred and having the angle-iron secured at its lower edge, the narrow leaf having one of its edges hinged to said angle-iron, the upper and 3 lower wide leaves hinged together while the free edge of the upper leaf is hinged to the narrow leaf, the guideway extending at the I sides of the doorway throughout its height,

the trunnions extending from the wide leaves into said guideway, the guideway at the sides of the doorway and extending throughout a portion of the height of the latter and inclosing the ends of said leaves, the pulleys suitably supported at the top of the doorway at each side thereof, and the weighted cords passed over said pulleys and having their free ends connected to said trunnions, substantially as set forth.

4. In a shutter, the combination of a series of leaves hinged to each other so as to fold in horizontal disposition alternately in opposite directions, means for elevating and lowering said leaves while in extended condition, means for axially guiding said leaves, a guideway for holding said leaves as against folding on their hinges throughout a predetermined extent of their elevation while in extended condition, and means for effecting the folding operation of said leaves after they have cleared said guideway, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JAS. G. WILSON.
