Warren STATES PATENT ACHILLE BATAILLE, OF NEW YORK, N. Y.

METAL DOOR OR GATE.

SPECIFICATION forming part of Letters Patent No. 448,314, dated March 17, 1891.

Application filed April 21, 1890.

T0 aZZ whom it may concern.-

. Be it known that I, AOHILLE BATAILLE, a citizen of the United States, residing in the city and State of New York, have invented an Improvement in Metal Doors or Gates, of which the following is a specification.

In elevators for buildings and in warehouses gates have been made use of that are composed of parallel bars crossing each other and pivoted at the intersections and known as lazy-tongs gates but these gates are not well adapted to separating one portion of a warehouse from another, as they do not prevent the passage of fire.

Doors have been made of sheet-iron upon iron frames; but these doors are heavy and require considerable space for opening and closing, and in instances Where such doors are fitted to slide they require a large recess in the wall or a space for movement equal to their own width, and these conditions often cannot be obtained in buildings. Besides this the doors become warped in cases of fire and bind in their frames in such a manner that they cannot be opened.

My present improvements are for combining with the lazy-tongs gates or doors metal slats that are attached to the lazy-tongs and move with them, and in opening and closing the doors the slats slide one upon another and overlap to a greater or less extent, and the lazy-tongs door or gate provided with these metal slats occupies but little more space when it is open than the ordinary lazy-tongs gate, and the sheet-metal slats can be made to entirely close the doorway and form a fireproof door, or they can occupy onlythe lower portion of the doorway in cases Where it is desired tohave the upper portion of the doorway open; or the sheet metal can be perforated with ornamental openings in cases where the portions of the slats do not require to be plain sheet metal.

In the drawings, Figure 1 is an elevation of the gate complete with portions of the intersecting bars removed to show the connections to the slats. Fig. 2 is a plan view in section at the line or w, and Fig. 3 is a sectional plan view below the line yy, representing the slats as slipped one over the other when the door is opened.

The doorway is of any desired size or char- Serial No. 348,774. (No model.)

acter, and in the same is the sill-rail A, usually in the form of a trough, and there is a lintel-guide B for the top of the door, and at O is the doorjamb, against which the door closes, and D is a door jamb or post to which the lazy-tongs are partially connected, the parallel crossing bars of such lazy-tongs being shown at E and pivoted together at their intersections, and F is the vertical bar at the moving edge of the door.

The lazy-tongs gate is pivoted at 2 to the post D, and the rivets or bolts 3 slide in slots in the upper and lower portions of the post D, and the connection between the lazy-tongs bars E and the vertical bar I is made by the rivets 4, which form pivotal connections, and the rivets or bolts 5 in slots in the upper and lower portions of the vertical bar F, and it is usual to provide a roller 6 at the lower end of the vertical bar F, resting upon the sillrail A to support the gate or door as it is opened or closed.

The gate thus far described is to be of any desired size or character, and it corresponds generally with lazy-tongs gates that have heretofore been made use of.

The metal slats are of any desired height and width. They may extend from the sillrail A to the lintel-guide B and slide at top and bottom in such rails, or the slats may only extend a portion of the distance vertically in the doorway, and such metal slats may be plain or perforated to a greater or less extent, and when perforated the openings may form ornamental designs. Each slat is stiffened by flanges or corrugations running vertically and lengthwise ot' the same. I have shown flanges 7 and corrugations or ribs at S, and I have shown four of these sheetmetal slats; but the number may be more or less. Each slat is permanently connected with the lazy-tongs bars at or near one of its edges. The slat nearest the moving edge of the door is permanentlyconnected to the vertical bar F, so that it moves with the same. The other sheet-metal slats are connected at the intersections of the lazy-tongs bars permanently by the rivets 9 to form pivots for the lazy-tongs bar and are in line with the

pivots

2 and 4, and upon the slats G are slide-guides 10 and 11 above and below the pivotal connections 9 and in line with the too same, and in these slide-guides 10 and 11 are pivot blocks or studs 12, connected with the pivot bolts or rivets at the intersections of the lazy-tongs bars. When the dooris closed in the doorway, the slats G lap upon each other slightly at the adjacent edges, and as the door is opened and the crossing bars of the lazy-tongs gate come nearly parallel-to each other the sheet-metal slats G can slip bodily one over the other and assume the position shown in Fig. 3, and they do ,not interfere with the opening or closing of the lazy-tongs gate, and when such gate is opened the slats may occupy the same space widthwise as the folded lazy-tongs bars, and if the number of metal slats is less and the slats are wider such slats may project at their free edges past the vertical post D into a recess in the wall adapted to receive them; or in cases where the door-post D is pivoted at the top and bottom, as is frequently the case in this class of doors, and as shown in Patent No. 358,956, granted March 8,1887, the lazy-tongs door and the slats may be swung upon such post D into a position at right angles to that occupied by the door when closed.

It is to be understood that the slide-guides 10 and 11 for the pivot-blocks 12 need not occupy more space than the lazy-tongs bars when folded together. Hence the addition of the sheet-metal slats does not permit the lazy-tongs door or gate being actuated in the ordinary manner and shutting up as closely as usual.

The metal slats are sometimes made either partially or wholly of open-worksuch as strips of sheet metal or wires interwoven and supported by suitable frames or borders and these slats are preferably placed at slightlyincreasing distances from the plane of the lazy-tongs bars, so as to allow one slat to slide over the other and remain parallel to the gate or door.

I am aware that in metallic shutters the metal slats have been fitted with crossing or lazy-tongs bars to raise or lower them and maintain their parallelism; but in this case they would if the surfaces of the sheets of v metal coincided. In my improvements these difficulties are avoided, and the metal slats slide closely one against the other.

I claim as my invention 1. The combination, with the lazy-tongs door or gate, of metal slats lapping one upon the other and having flanges on their edges turned toward the lazy-tongs and pivotal connections against the flanges for the lazytongs bars, substantially as set forth.

2. lhe slats G, having flanges at one edge and stiffening-ribs at the other edge and the flat surfaces contiguous to each other, in combination with the 1azy-tongs door or gate, the attaching-pivots 9,and the slide-guides upon the metal slats against the flanges and the pivot blocks or studs contiguous to the intersections of the lazy-tongs door or gate and within the slide-guides, substantially as set forth.

3. The lazy-tongs door or gate, the post D, to which the same is connected, and the vertical bar F at the moving edge of the lazytongs door, in combination with the metal slats G,having flanges at their edges and the flat surfaces lapping upon and against one another, and one of which slats is connected to the vertical barF,the slide-guides 11 upon the slats and against the flanges, the pivots for the lazy-tongs, and the pivot blocks or studs within the slide-guides, substantially as set forth.

Signed by me this 16th day of April, 1890.
