GATE.

Application filed September rl`he object of my invention is to provide a gate of simple, durable and comparatively inexpensive construction, having a remote control.

A further object is to provide a gate which can be easily opened or closed by pulling a control cord, which may be located wherever convenient.

Still a further object is to provide such a gate having a hollow gate post at t-he hinged end in which the operating mechaism is enclosed.

Still a Afurther object is to provide novel means whereby the gate is automatically unlatched when the control cord is pulled for opening the gate.

l/Vith theseand other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objectsconn teniplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying draw ings, in which:

Figure 1 is a plan view of my gate illustrating it in closed position.

Figure 2 is a side elevation of the same.

Figure 3 is a sectional view on the line 3w3 of Figure 2.

Figure 4 is a sectional view on the line 4 4 of Figure 3; and

YFigures 5 and 6 are views of the mechanism within the hollow gate post showing them in different positions, which they asysume during operation.

On the accompanying drawings, I have used the reference numeral to indicate a fence, which is of any construction desirable'. Two gate posts 11 and 12 are provided, and they are preferably set in concrete to maintain their alignment.

yHinge members 13 are secured to the gate post 11.

A gate 14 has hinge members 15 secured thereto.

A hinge pin 16 extending through the members 13 and 15 permits the gate 14 to swing about the 'post 11.

On the gate post 12, a stop rail 17 is pro- -v-idedfor the gate 14to swing against when the gate is closed. For retaining the gate 14 in closed position, a catch member 18 is secured to the post 12.

A second latch member 19 is slidably mounted in the end member 20 of the gate 10, 1925. Serial No. 55,520.

14, and is positioned to coact with the catch 18 when the gate is closed leaf spring 21 holds the latch 19 in po.- sition to engage the catch 18, and as clearly shown in Figure 1, the latch 19 will be pushed bacl against the action of the spring 21 by the cam surface 22 of the catch 18.

Before opening the gate, it is necessary to unlatch the latch 19 and the mechanism for accomplishing this result, will be later described.

A hollow box-like post 23 is composed of sides 24 and ends 25, and is secured to the lgate post 11. Three sets of guide grooves 28 are formed in sides 24 of the post 23.

A weight member 27 is slidably mounted in the center groove 26, and engaging mem bers 28 and 29 are slidably mounted in the outside grooves 26.

Loosely mounted on the top of the hinge pin 16 is a pulley 30. A cable or rope 31 is attached at its center to the pulleyv30 by a screw or clamp 32.

The-ends of the cable '31 extend through openings 33 in one of the sides 24 of the post 23 and thence over pulleys 34, and down to the engaging members 28 and 29 to which they are secured. Two stop Vmembers 36 and 37 are formed on the pulley '30 in positionto engage opposite sides of the gate 14 and toy allow slight rotation of the pulley 30 relative to the gate 14. The pulleys 34 are supported by a partition in the post Hinged at 38 to each of the engaging members 28 and 29 is plate 39 having at its center an extending portion 40. At the edges of the plate 39 are extensions 43 which are bent as clearly shown in the lower part of Figure 3.

The extensions 43 extend through openings 44 in the engaging members 29.

A light leaf spring 42 bearing against the extension 4() normally holds the plate 39 in. the position shown in the lower part of Figure 3. The extensions 43 limit the position of the plate 39 as it is forced outward by the spring 42.

On each end 25 of the box 23, stronger leaf springs 41 are mounted in the path of the extensions 40.

It will be seen that when the engaging member 29 or 28 is raised so'that the extension strikes the spring 41, the spring 41 will cause the plate 40 to assume the positiim ilhiistrated in the upper part ol Fig ure 8, against the action of the weaker spring 42. The weight member 27 provided with ears which are designed to coact with the extensions 43 when said extensions are held away from the members 28 and 29 by reason oit the springs 42.

Additional weights 46 in the quantity necessary to operate my gate, are hung by chains 47 on the weight member 2T.

A control cord or rope 48 is secured to the weight member 27, and extends upward through a hole 49 in the partition 85 and through a` hole 50 in the top 51 ot the post 23.

The rope 48 extends to any point convenient 'for operating the gate trom, or a plurality of control cords 48 may extend to a plurality ot remote control points so that when any one of said cords are pulled, the gate is caused to operate.

An ear 52 is secured to the pulley 8O to which a short cable 55 is attached. rllhe cable 53 extends around a pulley 54, and has its other end attached to a lever 55, which is pivoted to the gate 14 at 60.

A rod 56 extends through an opening 59 in the latch 19, and terminates in a head 58.

From the foregoing, it will be seen that when the pulley 30 is moved clockwise in Figure 1, the stop 37 will leave the gate 14 and the stop 36 will engage the gate. This slight movement will pull the cable 58, swing the lever 55 and cause the rod 56 to slide to the lett in Figure 2.

The head 58 engaging the latch 19 will cause it to slide against the action of the spring 21, thereby unlatching the gate to allow it to be opened. lt is obvious, retorring to Figure 2, that the latch 19 is tree to move to the left without aillecting the rod 56, which it does when the latch is pushed back by the cam surface 22 ot the catch 18 when the gate 14 is nearly closed.

In the operation of my gate, the cord 48 is pulled, raising the weight member 27 and the weight 46.

As the member 27 nears the upper limit of its movement, the ears 45 engage the extensions 423, and force them against the engaging member (28 or 29 as the ease may be) against the action oi the spring 41, as clearly shown in Figure 5.

Further movement of the member 27 causes the ear 45 to pass the extensions 48, thereby allowing the spring 41 to cause the plate 40 to again assume the position shown in the upper part ot Figure 3.

Upon releasing the control cord 48, the member 2T starts to descend due to its weight and that oit the weights 46. The ears 45 then engage the extensions 48, and thereby cause the engaging member 28 to also descend. This pulls the cable 31 secured to the member 28 and rotates the pulley 30.

Lessines rlhis causes the gate to be unlatched as above described, and then the stop 36 engages the gate and swings it to the open position, shown in dotted lines in Figure 1.

rihe post 6l has a bumper 62 made ot rubber or other suitable material to cushion the gate in open position. Before the gate 14 is fully opened, the weights 46 rest on the ground as illustrated in Figure 6, the chain 4T being slack.

rthis automatically relieves the cable 48 ot the weights 46 so that the gate 14 is not SlammerL so violently against the stops or 1T at the end of its travel when opening or shutting.

Vlhe weight member 27 is su Ylicient to continue the opening or shutting ot the gate 14 thn weights 46 rest on the ground and nly hold the gate in open position against the bumper 62 or to latch the gate when closing it.

ililhen the control cord 48 is again pulled lor raising the weight member 27, the ears 45 are disengaged from the extensions 48, and a similar engaging action takes place between the weight member 27 and the engaging member 29. T his action rotates the pulley 30 counter-clock wise in Figure 1, the stop 37 engages the gate 14, and it is then closed.

1t is obvious that movement downward ot the engaging member 28 raises the member 29 to position to be engaged by the weight member 2l' and vice versa..

For access to the parts of my device for oiling or adjusting the weights 46 etc., l provide a door 63, which may be hinged at 64 and latched at 65.

lt is also obvious that the weight member 27 holds the gate 14 open and therefore no latch is necessary to keep it open.

F rom the description here given, it will be seen that l have provided a gate which accomplishes the objects contemplated and does so with a minimum ot parts.

1n operation, l have found that ten pounds weight is sufficient to quickly open an ordinary size gate, and it is therefore seen that but little energy is required to operate a gate of this type.

Some changes may be made in the construction and arrangement of the various parts ot my invention, and it is my intention to cover by my claims, any modilied orms of structure or use of mechanical equivalents, which may be reasonably in-v cluded within their scope.
