GATE-LATCH on THE LIKE.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, EDWARD J. BRADY, a citizen of the United States, residing at Cedar Falls, in the county of Blackhawk and State of Iowa, have invented-certain new and useful Improvements in Gate- Latches or the like, of which the following is a description.

My invention belongs to that general class of devices known as gate latches, and relates particularly to a device for locking swing ing gates, the same being particularly adapted for that style of gate that may be swung in either direction. The invention has among its objects the production of a gate latching device of the kind described. that is simple, convenient, durable, efficient and satisfactory, that will not easily get out of order nor be affected in its operation by weather conditions, and which may be used wherever found applicable. The invention has particularly among its objects the production of a device that will securely and automatically lock or secure the gate against opening, regardless of whether the gate is of the rigid or tilting type, or of wood, steel or other material. It has among other objects the production of a device that I will not be rendered inoperative or ineifi- 30 cient when, the gate sagsror is tilted, or if the fence or gate posts shouldsag or settle, and which cannot he accidentally operated by stock or otherwise. It has among other objects the production of a device which may consist of a plurality of locking elements or arms, all of which may be operated or controlled simultaneously in a simple manner, but which elements are independ? cntly operative and controllable, so that in case any of the elements are notoperated or are rendered inoperative, for ,any reason whatsoever, the efficiency and effectiveness of the device will not be impaired, butthat the operative parts will perform theirusual functions and accomplish the result desired.

Many other objects and advantages of the construction herein shown and described will appear to those skilled in the art from the disclosure herein made.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims, r 5

In the drawings, wherein like reference characters indicate like or corresponding parts, V Figurevl 1s a view in elevation ofan adjustable tilting type of gate with my latch the complete device, the upper portion being partially shown in section;

Fig. 9 is a side elevation of a portion of the device; v

. Fig. 10 is a sectional view, similar to Fig.

8,'illusti'ating a-slight modification;

Fig. 11 is a sectional view taken substantially on line 11 11 of Fig. 10, and

Fig. 12is a front elevation of the device, illustrating the independent action and control of the parts.

Referring to the drawings, in which the preferred embodiment of the invention is shown, 1 and 2 represent any style of fence or gate posts between which is arranged the gate which, as previouslystated, may be the rigid type or that type known as a tilting gate, that illustrated being adapted to swing in either direction. Referring particularly to Fig. 1, the gate shown consists of the end bars 3 and 4:, and connecting bars 5 and 6,

the partsbeing suit-ably connected in any desired manner. The gate maybe covered with any suitable wire, wire netting or fabric, this depending on the particular use.

to which the gate is to be put. In the gate shown end bar 3 is pivotally secured to and supported by the post 1, the opposite end being the free end of the gate, which may be swung in either direction past the post 2.

The, gate illustrated is of the tilting or adjustable type, so that the free end of the gate may be raised orlowered as desired, the

locking device being applicable'for the same, regardless of its adjustment or the means for supporting the free end of the gate.

The complete latch or lock illustrated in the drawing consists substantially of two or more latch or locking devices arranged to be ception of the slight differences hereinafter referred to. It is immaterial whether or not the devices are placed on the gate post and arranged to engage the end bar of the gate or on the gate and arranged to engage the gate post, but the first arrangement being preferred, I have illustrated that.

Each latch preferably consists of a base plate 11, provided with a. pair of extending

parallel flanges

12 and 13, arranged one above the other. These are formed with the shoulders or abutments 14c and 15 (see Figs. 3 and 9) and the plate is preferably recessed or cut away as shown at 16 (see Fig. 8). I also provide an inclined or cam face 17 on each side intermediate the shoulders 1d and the face of the plate, the purpose being more fully described hereafter.

Carried between the flanges is a gate engaging member 18, or latch, provided with the extending arms 19, the same forming substantially a V-shaped member or fork arranged to embrace the bar at when the gate is closed (see Fig. 5), the ends of the fork 19 being preferably enlarged so as to guard against injury to stock that might rub against the same in passing through the gate opening. In the preferred construction shown, I pivotally secure the member 18 between the flanges by a tubular pin or

bushing

20, 21 being a spring washer which may be inserted as shown to act as a brake or yieldingly oppose the pivoting movement of part 18 about the pin 20, he pin 20 is shown with the'tubular opening tapered as at 22, and the same is supported in place by the shoulder or flange 28 formed on flange 18. Tapering the pin 20, as shown, prevents binding on the rod.

was before mentioned, two latching devices are shown as constituting the omplete latch or lock. Extending through the tubular pins 20 on the upper and lower flanges, as well as through any intermediate pins, in case more than two latch devices are employed, is an operating or latch release controlling rod 24;, which carries means for engaging the several members 18. I have shown two forms of engaging or latch locking members,the same beingsubstantially similar, except that the upper one is capped over,.as will be hereinafter referred to. The upper member 25 is shown in Figs. 4, '5, 6

and 7, and consists of the part 25 formed with a chamber or recess 29 therein, hooded or closed at the top, the same having a depending leg or fork engaging member 27 at each side. In the construction shown the recess in the head is elongated rather than circular. The member 26 is substantially identical, the legs 28 being similar to the legs 27 of the upper member, except that the top. is open so that the rod 24 may pass therethrough. Obviously, member 26 might be employed at the top of the rod in lieu of member 25, and in the case of intermediate latches, members similar to 26 would ordinarily be employed. The

members

25 and 26 are secured to the rod by means of the pins 30, or their equivalents, for the purpose As is obvious, the head locking members may be tilted on the operating rod without binding. I preferably place a collar or stop 31 at the lower end of the rod, and, if desired, a spring 32 may also be arranged as shown (see Fig. 6).

In the modified construction shown in Figs. 10 and 11, 2 represents the fence post, 36 the plate carrying the flanges, between. which is arranged the forked member 37. 39 represents the legs of a fork engaging member. In this case, in lieu of the spring washer previously described, or supplemental thereto, I roughen the top face of the fork member, as at 38, and similarly form the lower end of the legs 39, as shown at 40 in Fig. 11. This tends to retard the movement of the forked member and prevent back throw when the gate is thrown from one side to the other.

The operation of the devices may be briefly explained as follows: Assuming that the gate is shut, so that the forks and fork engaging members and rod 21- are substantially as shown in 1, 4:, 5, 6 and S, if it is desired to open the gate, the same is released by raising the rod 24:, thereby raising the fork engaging members. (See Fig. 2, in which engaging member 26 is raised). Pressure applied on the gate will cause movement of the fork members substantially as indicated in Fig. 8, and by the dotted lines in Fig. 5, the

legs

27 and 28 being raised out of engaging position between the shoulders 14 and 15 on the base plate and shoulders 18 on the forked member, as shown in. Fig. 8. The fork member moves sufiiciently to release the gate end bar a, permitting the gate to be swung open as muchas desired. The fork members remain in their adjusted or open position so as to engage the gate when again moved to closed position. Any back throw or accidental movement is normally prevented by the spring washers 21, these acting substantially as yielding brakes. Of course as soon as the forked members have moved sufiiciently so that the fork members are under the ad- .ber, the engaging member drops into position to engage the shoulder on, the other side, thereby not only stopping the movement of the gate, but automatically engaging the fork so as to lock the gate shut until the parts are again manipulated as described. It is obvious that the operation would be the same regardless of how many forks were employed. V

The device is operative if only one fork is engaged, so that the efficiency oroperation of the device is in no way impaired in case the gate is tilted sufliciently to engage only one'fork, or if the gate or gate posts should sag or otherwise get out of normal arrangement the device would still be operative. This may best be described by referring to Fig. 12, in which the upper fork is shown in closed or locking, position by the full lines and by dotted lines as thrown to the right, while the lower fork is shown as thrown to the right. -Assuming that both forks are to the right andthe gate is opened, the upper fork and engaging member will be as indicated in the dotted lines, and the lower fork .and engaging member as indicated in the full lines. In this case it will be noted that the pins 30 are in engagement with the lower end of the slots 29 in the

members

25 and 26. Assume that the gate is moved to closed, position, but that the lower fork is not engaged or moved, the upper fork being moved to the position shown in the full lines: As soon as the fork reaches the closed position shown the leg 27 will drop down so as to engage be.- hind the shoulder, locking the fork against movement. The member may drop to engaging position, due to the slot 29, even though the rod 24 does not drop. Referring to Fig. 12, it will be noted thatin the dotted lines the locking member rests one side upon one of the flanges, this point being substan-' tially a fulcrum point, so that when the latch is moved to closed position the leg 27 (Fig. 12) moves faster than the ordinary drop, due to gravitation on account ofthe leverage at the .ful'c'rumpo nt mentioned.

In case that'the "upp'er'f ork is not moved, .but the lower fork movedback, member 26 would likewise drop into operative engaging position by virtue of its weight. and

leverage, so that the lower pin 30 would engage in the upper end of the slot 29.of

part 26. -This is important, as while the devices, regardless of the number of'forks, may be. simultaneously released or locked, they are also independently operable. Owing to the open spaces between the

shoulders

14, 15 and 18, the parts are freely operable and but slightly affected by weather conditions. In case the rod carrying the fork engaging member should turn or partially rotate, owing to the cam or beveled faces 17, the fork engaging mem bers will be guided to operative position, thereby bringing the rod back. to proper adjustment. From the above description it will be seen that the device is substantially applicable for any type or style of gate;

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit .of my invention, hence I do not wish to be understood as limiting myself to the exact construction, arrangement or combination of parts herein shown and described, or uses mentioned.
