i. a: :citizeneof vthe United States, and resident of thezborough of Garwood, in. the county of -.U-nion and State of New-'Jersey, have inventechcertain new @and useful lmprovements in GateiLocks, of' which the: following isa;specification.

This invention relatesto locking mecha- 10 nism zfor :gates,aand it has for its, object to provide a simple, inexpensive and durable construction whereby ax-gate when closed can be "readily locked -.orunlocked-ras de- "sired;

'With this object in iview my invention comprises :novel structural features land combinations: of parts which will be hereinafter described: and claimed.

Inthe -draw=ings- I Figure-lis asidev elevation of aiswmging ggate structure equippedwith locking mechanism embodying the preferred :formof my invention the full and 1 dotted lines showing said :mechanism' int locking 1 and unlock- Zing rpositions, respectively.

Fig. 2 is a vertical isection'through the st'ructure,-:-as-=on'lthei line 2-'12='of Fig. 1, but showing the mechanism in unlocking position.

The form of gate frame herein selected for illustration comprises upper and lower rails 10 and end bars 11, 12. One end of the frame is hinged, as at 13 to spaced-apart brackets on an adjacent post 14, and the other end of the frame is equipped with my improved mechanism whereby the gate when closed can be locked to the adjacent post 15. In the present instance the rails 10 and the bars 11, 12 are united by paired channelled check members 16, as set forth in Letters Patentof the United States No.

I 1, 273,359, dated October 29, 1918.

Fitted in and secured to the channels of the respective cheek members of the end bar 12 are the limbs of two guide brackets 17 for a vertically-movable gravity bar 18 which is adapted to be moved into and out of locking relation with a suitably disposed keeper when the gate is closed. In the pres- 50 ent form of my invention the keeper comprises a metal loop 19 which is suitably located near the base of the post 15 so as to extend immediately under the lower guide bracket 17. The upper end of the locking 55 bar 18 extends above the upper guide the post. The upper end of the bar 18 has -formed-onor otherwise fixed to it a-longibracket 17 and is bent oifset', as at 20, to afford ashou-lder which co-acts with the top of the bracketin-a manner to limit the downward movement ofthe bar, asshown. The upper end of-the bar 18-is coupled to a vertically swinging member-21 which is plvoted atone endto the Lip-projecting, portion ofthe frame-bar, as at 22, the coupling beingfof such character that the-upward and downward motion of the member is positively translated to thelocking bar so as to move the latter respectively into and out of lockingengagement with thekeeper.

-Inthe present'instancethe member 21 con- .slstsofa hasp which is mounted and arranged to be-swung to and from the top of the adjacentpost 15, whichpost has an upstanding eye-extension23 which is embraced by the hasp when the latter is swung upon tudinally-slottedhorizontal arm 2& which is looselyembraced by the limbs of the hasp,

and the hasp is'providecl intermediate its 'endswith -a cross-bolt .25 which extends freely through the longitudinal slot'26 of the arm 24, thus providing-a pivotalslidable coupling between the arm and the "hasp.

The construction and relative arrangement of the parts just described are such that when the hasp is swung toward and from the top of the post 15, the bar 18, by virtue of the connection between the hasp and the arm 24, is lowered and raised into and from looking engagement respectively with the keeper, as shown by the full and dotted lines, respectively, in Fig. 1. When. the hasp is swung upon the post 15 a suitable padlock can be applied to the eye-extension 23 so as to lock the hasp to the post and the bar in engagement with the keeper, thus effectually locking the gate in closed position.

It is to be noted that when the hasp is swung upward to the position indicated by the dotted lines in Fig. 1 the bolt connection between the hasp and the slotted arm is to the left of the pivot 22 of the hasp, thus holding the bar 18 in its raised position until the hasp is manually swung toward the ad- 1 5 jacent post in the locking operation.

The locking mechanism above described is extremely simple, effective and durable. The constituent parts being few and their connections positive there is little liability vention and the scope of the appended claims.

I cla1m I 1. The combination with a grate structure, of a vertically-movable locking bar thereon having an angularly-disposed member fixed on the bar, said member having a longitudinally extending guide portion, a stationary keeper for said bar, a swinging member pivoted to said structure, and a connector relatively fixedon said swinging member in spaced relation to thepivot of the latter and slidably mounted in said guide portion, whereby the bar is raised and lowered concurrently with the swinging member.

2. The combination with a gate structure, of a vertically-movable lockingbar thereon having a longitudinally slotted angularlydisposed arm, a stationary keeper for said bar, a swinging member pivoted to said structure, and a bolt mounted on said member intermediate its ends and extending loosely through the slot of said arm, whereby the bar is raised and lowered concurrently with the swinging member.

3. The combination with a gate structure having guide members thereon, of a vertically-movable locking bar mounted in said members, a support located adjacent said bar when the gate is closed, said support having a hasp-receiving element, a stationary'keeper for said bar, a hasp. member pivoted to the gate structure and movable to and from said element, and a couplingbetween said hasp and bar whereby the motion of one is transmitted to the other to effect the looking or the unlocking of the hasp and bar in relation to the hasp-receiving element and the keeper respectively.

4. The combination with a gate structure having guide members thereon, of a vertically-movable locking bar mounted insaid members, a support located adjacent said bar when the gate is closed, said support having a haspreceiving element, a stationary keeper for said bar, a hasp-member pivoted to the gate structure and movable-to and from said element, an angularly-disposed arm on said bar, and a pivotal slidable coupling between the-hasp and said arm.

5. The combination with a gate structure having guide members thereon, of a vertically-movable locking bar mounted in said members, a support located adjacent said-- bar when the gate is, closed, said support having a hasp receiving element, a stationary keeper for said bar, a hasp-member pivoted to the gate structure and movable to and from said element, a longitudinallyslotted angularly-disposed arm on said bar, and a cross-bolt extending through the hasp Signed at Garwood, in the county of Union and State of New Jersey, this 15th day of March, 1921;
