FOLDING GATE.

SPECIFICATION forming part of Letters Patent No. 417,898, dated December 24, 1889.

Application filed May 8, 1889. Serial No. 310,012. (No model.) i

. ous patterns have heretofore been made of a system of bars or levers of the well-known lazy-tongs pattern. It is frequently required that these devices be closed up into a space the boundaries of which are limited, and it has heretofore been difficult to construct gatos or guards of this pattern so that they would shut up or close within a given limit,

and it has also been inconvenient always to' open and close gates or guards of this pattern by the usual handle, and occasionally it is de# sirable that these gates or guards be susy pended overhead and have their movement vertically, and in such cases it is necessary that the same be opened and shut otherwise than by a simple handle. y

The object of my invention is to construct a gate or guard of the lazy-tongs pattern so that the same can be closed within a limited space, and also to provide means for opening and closing said gates or guards from a given point without the use of the usual handle; and in carrying out my invention I employ narrow bars or levers in the construction of the gate or guard, in combination with outer overlapping bars that aire wide. These wide bars provide the necessary strength and stiffening to the gate or guard, and because they overlap the narrow bars the whole gate can be shut up into a smaller compass than would be possible if all the bars were sufficiently wide to provide the necessary strength; and I employ also a spring device for assistingin opening the gate, and lever systems actuated by hand at a given point for opening and shutting the gate, so that the person who operates the gate or guard does not have to walk or move with the saine its full length of movement, but can operate the same while standin g still.

In the drawings, Figure l is an elevation of a gate or guard made according to my improvement. Fig. 2 is an elevation of a modification of the saine; and Fig. 3 is a section at the line c a: of Fig. l, with the bars or levers closed.

The gate or guard, l, is composed of a system of levers of the lazy-tongs pattern, in which a are the bars pivoted together at their intersections and forming the gate. The vertical bars or frames h b form the ends of the gate, and the vertical bars or frame c the center of the gate, and 2, 3, and e are the Iixed points at which the bars a are pivoted to the uprights h b' c, and the usual slideways and blocks are provided in these bars, at 5 and 6, for the motion of the pivots in closing or opening the gate. The bars a composing the system of levers are made quite narrow, their width being governed by the length of the gate and the space into which the same is to be shut up. Said bars are always made much narrower than in similar gates as heretofore made, and I provide external overlapping bars d of much greater width than the bars a, and said bars d are arranged as shown in Fig. l, forming groups of X-ligures, their extreme ends and centers being held together by the same rivets that hold the bars a, and these bars d, being', because of their width, of greater strength than the bars a, act to stiften the gate and provide the necessary strength to the same; and it will be seen that these bars d are connected to every alternate bar a and overlap the intermediate bars of; and these bars d may be of sufficient Width almost entirely to overlap the intermediate bar a if it is found necessary for the strength of the gate. These bars d might, if desired, be connected to every third or fourth bar a, it being evident that the size of the gate and the circumstances under which the same is to be used will govern the location, the number, and the width of these bars d.

At e, I provide a tube, vertically placed and parallel to the bars or frames b b c, and pivoted at 7 to one surface of the series of levers or bars c. The upper end of the tube e is slotted, and said slot receives at 8 an arm of the pivot, to which one end of the helical spring f is connected. This spring f is within the tube e, and its lower end is connected to the pivot 7. The action of this spring is con- IOO tractile, tending to draw toward each other the points 7 and 8, and this assists in openin g the gate by spreading the system of levers.

For opening and closingthe gate a rightangled or bell-crank lever 7L is employed, pivoted at 9 to the system of levers, and also connected thereto by a link pivoted at 10. There is a link 7c and rod 7o connected to t-he other end of the lever h, and one end of said rod lo is provided with a handle, and by the vertical movement of the rod 7o and link 7c the lever h is swung upon the pivot 9, and the linkt' moves the pivot lO nearer to the bar b or farther from it to open the gate, or the reverse. Instead of using the rod 7.a', an endless rope or chain Z (shown by dotted lines) may be employed, the same having` a handle and passing around pulleys, the respective ends of said rope or chain Z being connected to link lc at 11 and 12. This device will operate the lever hand link e' as effectively as the rod c, and the rope or chain l maybe of any desired length, so that a gate upon one floor may be operated from a floor above or below it.

The device shown in Fig. 2 is a hanging gate adapted to open and shut vertically, the system of levers a being centrally pivoted at 2 to the horizontal bar b, the slideways and blocks 5 and 6 being at the ends of the bars.

In this device I provide right-angled levers m n, pivoted at 12 14 in lugs fastened to the frame or bar b. These levers m n have pivoted to them links 0 o', which links in turn are pivoted to the ends of the bars a at 15 and 16, and a rod r connects the other ends of the levers fm n, so that the two levers operate together. By pulling upon the rod s the gate formed of the system of levers a is raised or lowered and opened or shut. The weight t, connected to an arm of the lever n, acts as a counterpoise to balance the Weight of the gate as the same closes, the efiiciency of the weight t increasing as the same descends to a horizontal position.

I do not limit myself to the exact construction of the operating-lever systems-for opening and closing the gate, as the same might be varied by existing circumstances.

I claim as my invention- 1. In a gate or guard composed of a system of levers of the lazy-tongs pattern, the combination, with the narrow bars a, of the Wider external overlapping bars d, substantially as and for the purposes set forth.

2. In a gate or guard of the lazy-tongs pattern,v the combination, with the bars a, oomposing thesystem of levers, of the vertical tube @,pivoted at 7 at its lower end and slotted at its upper end, and the internallyplaced helical spring f, connected at its respective ends, substantially as and for the purposes set forth.

3. In a gate of the lazy-tongs pattern, the combination, with the narrow bars a and the wider external overlapping bars d, forming the system of levers, and the metal end bar h, to which one end of such system of levers is connected by a pivot and slides, of a pivotedbell-crank lever, a link pivoted at its ends to one arm of the lever and to one intersection of the bars, and a rod connected to the other arm of the lever and adapted to be moved by a hand device for opening and closing the gate, substantially as specifi-ed.

4. In a gate of the lazy-tongs pattern, the combination, with the bars 0 forming the system of levers and With the horizontal bar b, of the levers m mpivoted to lugs upon the bar b, the links o o', pivoted to the levers and to intersections of the bars c, the rod r, connecting-arms of said levers m n, the operating-rod s, connected to the lever m, and the Weight t, substantially as and for the purposes set forth.

Signed by me this 3d day of May, A. D. 1889.
