well as serving to overcomeL the liability of' forgetfulness to lock the gate vatthe, re-

quired time whicli'frequently occursfowing to the present forms of gates ofthis class being 'usually locked by the use of-separate locking means, such as padlocks which are frequently misplaced or forgotten at the n time when the gate should be locked.A n

" The invention consists broadly of means providinga'socket on onefof the opposing end rails ofl the; collapsible members of 'a `i foldable gate, and thesocket has preferably a substantially'rectangular ent-rance of Vless dimension than the socket so that the edge portions `of the sides of the:y socket provide overhanging flanges. On the second-end rall is locking meanswhi'ch 4is operative only by a vkey lof 'a given form, and the locking means includes an approximately T-shaped Abolt for allowing its cross-arms toenter, the entrance lengthwise of said socket when the end rails are closed ftogether by theikeyk be- Y ing partly turned to unlock theflocking means yand to allow the cross-arms of the bolt kto engage the overhanging sidev flanges Vof thesoclret when the boltiis subsequently partly rrotated byl turning' the key to a position forlocking the locking means. ,The members of the gate being extensibly .ad-v

justable ytoward and from each other may thereby be effectually locked when closed against being surreptiti'ou'sly opened.v i

A further object of the invention is'gto provide a foldablegate of asimple, eiicient yand Vdurable construction -Which may be made in appropriate sizes and shapes. .i With these and otherobjects inv View, the invention willv be hereina'jffter more l fully explained with reference Ato the accompanying drawing forming a part of thisv speci-l fication in which similar 'characters offref? erence indicate corresponding parts in all the'views, and will then be pointed out in the claims at'th-e end of the description.

The foldable gate has twoV collapsible members' y10 11 which maybe of any of the commonly used extensibly adjustable forms, though the members ofthe gate illustrated are of the well known Bostwick type having structural parts whichneed not'V be lherein describedv since their construction is gener# ally understood.V The "opposite ends of the members 10, 11 of the gate yare suitably. supported in fixed positions -forallowing the spaced parallel verticalmails 12 ofk eachk membertobe slidably moved onthe lower and upper longitudinally disposed tracks or

rails

13, 14 toward and from each other in ythe usual fashion when the gate is opened Y lengths, and the bars of each end rail are cacho-fa U-shape in'crossl-section as well as .beingspaced apart 'at similar distances sothat the spaces between the bars of both rails' are in alinement.V The Ushaped bars of each end rail are disposed :with the free edges of their legs inopposed relation and eachpair of the bars are securedk together byv spaced cross-bars vor bolts v19. Y Between' the lower ends of the

bars

17, 18 of the end rail 15 is secured at 20 one end of a short bar or block, as 21, and between the upper ends of the

bars

17, 18 of this end rail is secured at 22 one end of a second short bar or block 23. Both of the

short bars

21, 23 protrude angularly from the end rail 15 for heilig received between the

bats

17, 18 of the end rail 16 to guide the bars of the end rail 16 into contact with the bars of the end rail 15 when the collapsible members 10, 11 of the gate are closed.

In the central part of the end rail 15 between its

bars

17, 18 is a socket 24 of substantiallY a rectangular shape having a bottom wal 25, side walls 26, 27 and a front wall 28. In the central part of the front wall 28 is an approximately rectangular' o ning or entrance 29 of a less dimension t 1an the socket so that the edge portions of the entrance provide

ovcrhanging flanges

29, 29", 29, 29d. This socket may be formed by flattening a tube to a size so that the side walls 26, 27 snugly tit in the pair oit U-

shaped bars

17, 18 of the end rail 15, and theside walls of the socket may be secured, as at 30, 31 to the U-shaped bars ot the end rail. The sockethas a lower end wall 32 and an upper end wall 33. Both of the

end walls

32, 33 are preferably in the forms of bars which may be welded or otherwise secured between the U-shaped bars of this end rail.

Between the central parts of the bars 17 18 of the end rail 16 is means providing a lock 31 having a casing 35 which is pref erablv of a form composed of a block or bar 36 of a length Somewhat longer than the socket The block 36 is arranged between the pair of bars of the end rail 16, and the end portions of this block are bolted, as at 37, 37, to the bars. Through the central art of the block 36 is an opening 38 which is adapted to be alined with the center of f the entrance 29 of the socket 24 when the

end rails

15, 16 are in contact with the closing of the members 10, 11 of the gate, and the other end of the opening 38 may lead into a recess 39 provided in the central part of the outer face of the block. On the recessed face of the block 36 is another block or short bar 40 havingr its end portions fastened. as at 41, 41, to the block 36. In the central part of the block 40 is an opening 42 which is larger than the recess 39 of the block 36, and the lower part of the opening 42 leads into the recess. In the opening 42 of the block 40 is suitably xed the cylinder 43 of a lock 44 which may be of any well known combination type having the spring actuated spaced tumblers 45 adapted to be moved into and out of the spaced orifices 46 of the barrel 17 having a determined form of socket 48 for receiving the stem of a key, as 49, of a given type as may be required to an angular hole. Protruding from the barrel 47 is an angular stem or pin 52 which extends `through the hole 51 of the cap plate 50 and through the recess 39 into the opening 38 of. the block 36. The projecting portion of the stem 52 is seated inthe recess 53 in the free end of the leg or arm54 of a substantially T-shaped lock bolt 55. The crossarm `56` of the lock bolt is shorter than the length of the entrance 29 of the `-ocket-24 of the end rail 15, but this cross-arm is `of a length so that .its protruding ends are adapted to engage the overhanging side flanges 29, 29b of the wall of the entrance of the socket. The lock bolt is also of such a length that when inserted in the socket 24 its cross-` arm 56 may be rotatively moved to `and from` crosswise and lengthwise positions in the socket.

In order to lock the gate the members 10, i

11 are moved toward each other so that the

end rails

15, 16 are in proximity and so that the guide bars l21, 23 of the endl-ail 15 `are moved between the pair others 17 18 of the end rail 16. must be in a position so that the head or` arm 56 of the lock bolt `55 extends crosswise of the end rail 16 before the key can be inserted in the barrel of the lock.` Whenthe key is :inserted inthe barrel for operating the tumblers 45 the barrel and lock bolt are then turned half of `a revolution to dispose the cross-arm 56 of the lock bolt in a vertical position. The members 10. 11 are then moved to cause contact of the

end rails

15, 16 at which time the lock holt with its crossarm will pass into the socket 24 through its entrance 29, and by rotating the key one- The barrel 47 of the lock 34 i half of a revolution the barrel and bolt of the lock will be likewise revolved `for positioning the cross-arm of the bolt crosswise of the interior of the socket into engagement with the edge portions of the sides of the wall of the entrance. as shown in dotted lines in Figs. 2 and .4 of the drawing. Thus the end rails 15. 16 of the members of the gate must be locked together before the key can be withdrawn from the lock. and b v requiring the use of the ke)Y in this manner the liability offorgetfnlness to `lock the` any of the advantages ofthis invention,

therefore, I kreserve-torx'nyselfthe right to make such changes as fairly fall within the Y Y be moved to and from eachother, said ra1ls sco ethereof.: y
