1 Claim. 4(cl. 292-148) This invention relates to a new and useful gate locking device particularly adapted for locking double fence gates, although as will become clearly apparent its utility is by no means limited thereto.

The locking of double gates is particularly diicult because each gate section is movable relative to the other, and it has been our experience that conventional double gate locking devices heretofore commonly used are subject to being pried apart.

Accordingly, a primary object of our invention is to provide a locking device adapted for use with double gates and which cannot be pried apart.

Another object of our invention is to provide a gate locking device wherein each part thereof comprises an integral part of the gate.

Still another object of our invention is to provide a double gate locking device which does not require a separate locking bolt.

In addition, it is an object of our invention to provide a double gatelock permitting movement of only one gate at a time.

It is also an object of our invention to provide the foregoing in a locking device which is relatively inexpensive, and which is extremely durable and dependable in use.

In accord with one aspect thereof, a Vgate locking device constructed in accord with our invention is characterized by the provision of a first lock part having a sleeve-like portion adapted to be secured to one gate upright, a second lock part having a sleeve-like portion slidable on another upright disposed closely adjacent the rst upright when the gateis in a position to be locked, the rst and second lock parts each having a normally generally vertically disposed plate portion projecting toward the other part when the gate is in locking position, with the upper edge portion of the second gate part being formed to provide an inverted channel section slipiitting over the upper edge portion of the rst lock part.

The foregoing and other objects, advantages and characten'zing features of a gate locking device constructed in accord with our invention will become clearly apparent from a perusal of the ensuing detailed description of a presently preferred embodiment thereof, in conjunction with the accompanying drawing forming a part hereof and illustrating such embodiment wherein like reference numerals denote like parts throughout the various views and wherein:

Fig. 1 is a side elevational view of a double fence gate with a locking device of our invention installed thereon;

Fig. 2 is a fragmentary elevational view thereof illustrating the operation of the locking device of this invention;

Fig. 3 is a sectional view of our gate locking device taken about on line III-III of Fig. 2;

Fig. 4 is a sectional view thereof taken about on line IV-IV of Fig. 2; and

Fig. 5 is a side elevational view of one of the locking device parts.


The presently preferred embodiment of gate locking device constructed in accord with our invention is illustrated in the accompanying drawing in conjunction with a double gate comprising gate sections 1 and 2 hinged to fence end sections fragmentarily illustrated at 3.

It Will be understood that the fence end sections 3 and gate sections 1 and 2 each carry fabric 4 secured thereto as by rail tie staples, together with brace rods 5, turnbuckles, tension bars and bands and other conventional fence hardware, all as is well known in the art.

'Ihe fence end sections 3 terminate in gate posts 6 adapted to be anchored in the ground in the usual manner, as indicated at 7, and gate sections 1 and 2 are oppositely hinged thereto as by upper gate hinges 8 and lower gate hinges 9. Hinges 8 and 9 pivotally support gate section uprights 11, with the gate sections having at their opposite ends uprights 12 adapted to be disposed closely adjacent one another when the gate is in locking position. The end uprights 11 and 12 are joined to top and bottom rails 13 and 14, respectively, as by gate corners 14' of known construction. Also, one gate section can be provided with a drop rod 37 slip-fitting through brackets 38 secured to one of uprights 12, the drop rod having a hand grip part 39 for movement in the direction of the arrow (Fig. 2) into and out of a center stop 40.

The foregoing is given by Way of illustration only, and is not per se a part of our invention.

The locking device of this invention is indicated generally at 15, and comprises a rst or keeper lock part 15 formed with a cylindrical sleeve portion 16 adapted to slip-fit over one of the gate section uprights 12. Embossments 17 are formed on diametrically opposed sides of sleeve portion 16, which embossments are .apertured in line with apertures in the associated upright 12 to receive a bolt 18 therethrough for xing lock part 15 in position on its upright 12 against movement relative thereto.

Lock part 15 has formed integrally with sleeve portion 16 thereof a generally vertically aligned -liat plate or ange portion 20 projecting generally radially of the associated upright 12 to lie substantially in a plane containing the longitudinal centerline thereof and of sleeve portion 16, the liange 20 being extended above the upper edge of sleeve portion 16 as indicated at 21. Flange 20 has an aperture 23 therein which is elongated generally radially of the upright 12 and sleeve portion 16.

The other locking device part 15 also is formed with a generally cylindrical sleeve portion 25 adapted to slipiit on the upright 12 of the other gate section. However, sleeve portion 25 is not fixed against movement relative to its upright 12, but is freely slidable and rotatable thereon, and is provided with laterally projecting, generally diametrically opposed hand grip portions 26 to facilitate lifting Vof-lock part 15" lengthwise of its upright 12.

It will be noted that sleeve portion 25 of lock part 15 is not completely closed, but has its opposite ends Aspaced apart by a generally longitudinal slot 27. One end of sleeve 25 terminates in a normally generally vertically aligned flat plate or flange portion 28 lying in a plane substantially parallel to a plane containing the longitudinal centerline of upright 12 and of sleeve 25. The upper edge of ilange 28 is extended above sleeve 25, as indicated at 29, and leads to a generally horizontal ange 31 in turn leading to a flange 32 substantially parallel to the upper end portion 29 of flange 28 and extending from the opposite end of sleeve 25.

The ange portion 28 of lock part 15" also is apertured, as indicated -at 33 (Fig. 4), the aperture 33 corresponding to aperture 23 of flange portion 20 and both apertures being adapted to receive therethrough the bow 35 of a padlock 36.

Lock parts 15 and 15" are slipped over the gate upj Y rights 12 priorato assembly of ithe gate sections'. Lock l v2,940,790Y

Thus, no separate, locking lbolt is necessary, and a simplerpadlock effectively holds the lock part 15" against movementlengthwise of itsV upright 12 out of locking engagement withz-thej loclrgpart 15'. So longV as the y' Y. locking'. parts V1&1" V'andV 15" are in locking position, the ange 'portions/29 and 32 of locking `part 15'f confine durable and dependable gateV locking device well adapted to secure double gate sections in locked position while obviously being adapted for use with single gate sections and with diierent types of gates from that illustrated in the drawing.

While only a presently preferred embodiment of our invention has been disclosedand described in detail here* in, the same has been dcne'by way of illustration only and without thought of limitation. AAlso, the term sleeve as used herein is meant to include other than cylindrical member-S. A .Y Y. Y, Y Y Y Having fully disclosedY and completely Vdezscribed Vour invention, together with its mode 'of operation, what we claim as new is as follows:

A gate locking devicevcomprisingya Ysliding lock part of one piece construction having" a sleeve portion and a flange portion projecting laterally thereof, said ilange portion being alined generally lengthwise of said sleeve portion andter'minating in ,an ,inverted channelY along its upperV edge, said sleeve portion having lateralprotubei anceson substantially diametricallyvopposite sides thereof for being manually grasped to facilitate lifting said slidingV lock part, ai keeper lock part of one piece con- Y struction having asleevewportionfa'nd alaterally project` ing flange portion alined generally lengthwise thereof, the upper edge `of said keeper lock part flange portion being received within said channel when saidk lock parts are iti flange portion 21 of lock part 15 therebetwee'nand pre- Y clude swinging of either Vgate section 1, 2Yby effectively precluding relative lateralpniovement between thjellocking device parts 15 and V15".v Theclose` confinement of an'ge portion "21 of one locking device part within the inverted channelr29, 31, `32 of the otherV locking device Y' part thus: positively holds the gate sections locked togethet-,iand Ythe flat tlange'rportions 20,21', 29 and 32, in'cooperation with the sleeve portions 16 and 25, eifectively hold'the gate sections Vagainst being'twisted out of alignment, thereby'etfectively resisting prying apart of either..V the gate sections or the locking device.

Accordingly, it is seen that the locking device of our invention fully accomplishes the aforesaid objects, and

lockingengage'ment, and'rneans providing an aperture in each of ,said flange portions, said apertures being alined wheny said lock parts are locking position to receive la lock member therethrough and one of saidrapertures being elongated laterally'of the associated sleeve por-1 tion, the depth of said channel being no Ymore than the z distance between said-upper edgeof said keeperlock part ange portion and the upper edge of the aperturetherein.
