METAL GATE.

" SPECIFICATION forming part of Letters Peten-t No. 673,192, dated Api-i1 so, 1901.

Applicant nea June 28,1990. seria No. 21,892. (No modera in Metal'Gates, of which the following is a` specification.

My invention relates to foldingiron gates for use on railway-cars, boats, elevators, &c. These gates are sometimes made of the lazytongs pattern and sometimes of parallel bars connected by lazy-ton gs bars. Heretofore in making such gates it has been usual to employ flat bars of metal placed face-.to face and pivoted together. These gates when closed occupy considerable rooln, because ,theadjacent meeting edges of the bars simply come together; and the object of my invention is to lessen the space occupied and to be able to compactly close the gate and at the same time retain the strength and effectiveness of the gate.

In carrying out my invention I employ bars each having two parallel longitudinal ribs upon one surface at either side of the center of the bar, and the respective bars forming the gate are connected in alternate oppositelyplaced pairs, so that when closed the adjacent meeting edges overlap. These bars may be connected directly together in the wellknown lazy-tongs form, or these bars may be placed vertical and parallel with one another and connected by a lazytongs system of smaller intermediate bars.

In the drawings, Figures l and 2 are elevations representing forms of gates embodying my improvement. the form of gate shown in Fig. 1 as closed. Fig. 1 is a sectional plan at a; of Fig. l in larger size, and Fig. 5 is a sectional plan at y y, Fig. 3, in still larger size, showing the gate closed and the bars overlapping. Fig. 6 is an elevation of the form of gateshown in Fig. 2 as closed. Fig. 7 is a partial plan view, in larger size, of the parts shown in Fig. 2; and Fig. 8 is a sectional plan at z z of Fig. 6 in larger size with the gate closed and the respective bars overlapping.

The main or principal bars a, composing the forms of gates, are each provided with two parallel longitudinal ribs b b upon one Fig. 3 is an elevation of` `surface at either side of the center of the bar and spaced at substantially the same distances from the edges that they are apart. These bars are to be arranged in alternate oppositely-placed pairs-that is to say, two connected bars will be placed with their fiat surfaces opposite or adjacent and the next pair of bars with their ribbed surfaces opposite or adjacent-and the bars are preferably connected together by pivot-pins c, the heads of which where the flat faces of the bars come adjacent are received in the grooves formed between the parallel longitudinal ribs.

In Figs. l, 3, 4, and 5 the form of gate shown comprises vertical parallel bars a, in pairs, with a system of lazy-tongs bars d e between and connecting the vertical bars a and which systems of bars d e close together, spreading vertically as the bars a. close and overlap, as shown in Fig. 5. The fact that the bars ct are adapted by their peculiar form to overlap at their edges enables the gate to be closed into smaller compass than has heretofore been possible.

In the form of gate shown in Figs. 2, 6, 7, and 8 the bars a are groupedin pairs of the lazy-tongs pattern and are connected to similar vertical end bars ff. These bars are of the form heretofore described, and when the gate is closed the edges overlap, so that the bars are brought closely together 'into compact form, occupying but little space.

In the construction and placing of the'gate, Figs. 1 and 2, the vertical right-hand bar is preferably movable and provided with a handle and roller in the lower end and the lefthand bar rigidly or pivotally fixed, Aso that the bars composing the gate are moved up to or away from the said left-hand bar in opening or closing the gate.

Both forms of gate shown are well known, my in vention relating particularly to the form of` bar employed for the gate. These bars are light in weight and stiff and rigid both length- Wise and crosswise, and because of these qualities a much smaller bar in cross-section can be employed in a gate of given capacity' than would be possible in the usual flat-bar gate.

I claim as my invention- 1. A metal gate composed of pairs of parallel bars, each bar having two parallel longitu- IOO dinal -ribs upon one surface at either sideof the center, `and 4spaced at substantially the same distance from the edges that they are apart, the bars of the pairs being oppositely and alternately placed and adapted when closed to koverlap at :the edges and-*pivotal devices for connecting the bars, snbstantially as set forth.

2. A metal gate composed of pairs of parallel bars, each bar having two parallel Elongitndinal ribs upon one surface at either side of the center and spaced at substantially the same distance from the edges that -gthey are apart, said bars being so placed thatthe bars of one pair are connected with their fiat faces turned inward and the bars of the next pair with theirA rib-faces turned inward, \the several bars being adapted when closed to over- .lap at :the edges, andineans for kconnecting the bars, substantially as set forth.

3. A metal gate composed of pairs of parallel bars, each bar having two parallel lpngitn- `subsirmltially as set forth- Signed by me this 20th day of June, 1900. ACHILLE F. BATAILLE.
