may be extended to its full length or only a portion thereof as desired.
Another object of the invention is to provide means for drawing the outer end pales of the sections of the gate together and to lock said pales in said position.
Still another object of the invention isto provide means for pivotally supporting the sections of the gates and for adjusting the pivoted pales of the gate relatively yto the perpendicular.
The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims.

Like numerals refer to like parts throughout the several views of the drawings.
In the drawings, 12 and 13 illustrate two sections of 'a gate, one of which preferably 12 is shown extended, while the other is shown folded. The sections as shown in Fig. 1 are constructed of a plurality of pales 14, 14 preferably arranged parallel and adapted to be moved laterally relatively to eachother. One of said pales, preferably the vend pale `15, constitutes a pivot pale about'the axis of which the gate is adapted to be swung. The pales constituting said gate are `connected together preferably at opposite sides and adjacent opposite ends by pairs of links 16 which permit said pales to b e moved laterally relatively to each other and to thepivot pale 15 a limited distance, this distance being limited by the straightening of the links 16 as shown at 12 Fig. 1.
. Each of the pairs of links 16 is pivotally connected together at 17 and to the pales 14 preferably byrivets 18, said rivets 18 also constituting the pivots for the links extending in opposite directions from each pale. The links 16 are constructed of such a width 'that the pales 141 will be permitted to be moved close together when folded so as to touch one another as illustrated at 13 Fig. 1,
thus occupying the least amount of space j possible, this space being governed by the diameters of said pales. |lihe links 16 are however merelyfor the purpose of limiting theflateral relative movements of said pales, but have nothing whatever to do with the controlling of the vertical movements thereof. To control said vertical movements a bar 19 is provided, said barbeing attached at 20 to oneof said pales, preferably the pivot pale 15, and having slidable engagement with each of said movable pales in transverse slots 21 preferably formed in brackets 22 secured to one side-ofeach of said pales. Rollers 23 are arranged at the upper and lower ends of said slots to engage the upper and lower edges of said bar. kThe upper series of links which connect the adjacent pales is preferably arranged even Lthe pales 14.
with the bar 19 and when so placed the links upon the side of said pales to which the brackets 22 are secured are pivoted by rivets 24 to the brackets 22 instead of directly to rihe bar 19 extends from the pivot pale 15 through the slots in each of the pales 14 and terminates adjacent with the outer face of the outermcst pale 25 of the series of pales constituting said gate when said gate is extended as shown in Fig. 1.
The outermost pale 25 is provided at its lower end with a caster 26 which supports said pale and incidentally the pales intermediate said cuter pale and the pivot pale 15 through the instrumentalities of the bar 19 and the upper rollers on said pales. At
least this a the case when a narrow gate isl to be used. The bar 19 is jointed at a point 27 just outside of the outer faces of the outermost pale 25 when the gate is folded, see Fig. 1, said joint being provided to permit the portion cf the bar projecting beyond said pales being lowered into the position shown in dotted and full lines in the right hand portionof Fig. 1.
The joint 27 is constructed in such a manner that the movable portion 2S of the bar 19 may be moved to the Vhorizontal position shown in Fig. 10 and in alineinent with the stationary portion 29 thereof, further movements of said movable member 'being limitedv Yby stops 30,thus it will be seen that with the outer end 31 of said 'bar supported by the outermost pale 25 and its caster, said movable portion will constitute a support for the intermediate pales.
It often happens that the gates are very long and not very high and when such is the case the movable portion 28 of said bar would be too long to permit its being swung downwardly to the position indicated in dotted lines Fig. 1 as it would strike the ground before it reached its lowermost position. To provide for such, said movable portion is still further jointed at 32 and 33, the portion intermediate said joints constituting a link 34, thus permitting said movable portion to be folded as indicated in full lines AF ig. land in which position it is held by a. hook 341 pivoted on one of the arms of said movable memberat 342 andadapted to engage a pin 343 formed upon the other section of said movable portion. The hook 341 is arranged within a recess 344 formed in the sides of the sections of said movable member andr represented by the lines a-cz, which permit said hook to lie flush with the side of said bar so as not to interfere with the sliding movement of said pales. l/Vhen the link is employed the portion 2S will no longer be capable of supportingthe intermediate pales, consequently it becomes necessary to provide oneV of the intermediate pales 14 or at least the pale which alines with the link 34 when said gate is extended,with a caster,
the pale coinciding with this position being marked 35, Fig. 1.
ln erecting a gate it often becomes necessary Yto vary the position of the pale 15 relative to the perpendicular and to accomplish this result hinges 36 and 37 are provided adjacent the upper and lower ends respectively of the pivot pale 15, said hinges being adjustable.
rlhe hinge 36 preferably embodies in its construction a bracket 38 see Fig. 4 having a base 39 by means of which said bracket is secured to the wall or support 40. A lug 41 extends laterally from said base 39 toward the pivot pale 15 and a i-shaped member or clamp 42 is adapted to straddle a cylindrical portion 43 formed on the pale 15. rlhe legs of the member 42 engage opposite faces of the lug 41 to which they are secured by a bolt 44 preferably extending through a slot 45 in said lug. The extremities of the U- shaped member 42 are bent' outwardly at 46 to receive screws 47 having screw-tlireaded engagement with the base 39 by means of which said U-shaped member may be moved toward and away from said base. To retain n the cylindrical pc-rtion 43 of the pivot paleY 15 at the closed end of the U-shaped meinber 42, a block 47 is secured within said member in Contact with said cylindrical portion.
The lower hinge 37 see Fig. 5 preferably embodies in its construction a base 48 having a groove 49 extending longitudinally thereof within which is arranged a block 507 said block having a vertically disposed cylindrical hole 51 adapted to receive the lower end 52 of the pal-e 15. 1A screw 53 having screw-threaded engagement with the base 48 is adapted to rotatably engage said block and as said screw is rotated and moved thereby longitudinally on said base, said block will likewise be moved. Set screws 54 in said base are adapted to be moved to engage said block and clamp the same in a predetermined position.
ln gates of this nature it vis vsometimes dihcult to bring the outermost pales 25 of the two sections of the gate together in order that they may be locked. To accomplish this a latch 55 see Fig. 6 has been provided, said latch being pivotally and slidably mounted upon a stud 56 secured to a bracket 57 on the member 25 of one of the sections of the gate. A slot 58 has been provided in said latch to permit the same to slide.
The outer end of the latch 55 is provided with a hook 59 which is arranged to engage a portion 60 of a strike plate 61 see Fig. 7 secured to the member 25 of the other section of said gate.V As the members 25 are drawn toward each other the end of the latch 55 passes through a slot 62 in the strike plate 61 until the hook portion 59 thereof drops over the portion 60. A lever 63 is pivoted at the rear end of the latchv 55, said lever having formed thereon a cam 64 which is arranged to engage the rear side of the bracket 57 during the rotation of the lever 63 on said latch land retract said latch, thus firmly securing the members 25 in close lcontact one withY the other.
The outer end of the lever 63 is provided with an eye 65 located in a position to aline with an eye 66 on the other member 25 when said members are` locked together. A shackle 67 of a padlock 68 is then passed through both of said eyes to lock the same together.
Usually in folding gates it has been diflicult where two sections are employed to properly aline the abutting pales, or in fact to keep the pales of one section of said gate in the same plane with the pales of the other section thereof. In the present gate this difliculty has been overcome by extending the bars 19 beyond the outermost pale of their respective sections a distance equal to the spacing of the adjacent pales of said gate as at 69. The ends of said bars are somewhat reduced in width so ythat their combined widths are equal to the width of the main portion of said bars, see Fig. 11, and when the gates are to be closed said ends are matched and the outermost pales 25 drawn together over said matched portion. One of said bars or the reduced portion thereof is provided with dowel pins 7 0 which are adapted to fit corresponding recesses 71 in the other member and positively position and lock said bars in alinement.
In Fig. 9 I have shown a modied form of gate in which adjacent pales lil are piv otally connected together by a single pair of links 7 2, said links being pivotally connected at their upper ends, and slidably connected at their lower ends to the pales 14 in slots 73, said slots limiting the lateral relative movement of said pales.
lWhile I have herein shown and described one specific embodiment of my invention for illustrative purposes, and have disclosed and discussed in detail the construction and arrangement incidental to one specific' application thereof, it is to be understood that the invention is limited neither to the mere details or relative arrangement of parts, nor to its specific application herein shown, but that extensive deviations from the illustrated form or embodiment of the invention may be made without departing from the' principles thereof.
