Application May 3, 1949, Serial No. 91,137

This invention relates to a gate operating mechanism, and more particularly to a mechanism for opening and closing a farm gate.

The object of the invention is to provide a .mechanism which will enable the occupant of a vehicle to open and close the gate without alighting from the vehicle.

Another object of the invention is to provide a gate operating device which is constructed so that a person can open and close the gate without dismounting from a horse, or alighting from a vehicle.

A further object of the invention is to provide a gate operating device which is extremely simple and inexpensive to manufacture. I

with the operating mechanism, according to the present invention;

Figure 2 is a side elevational view of the gate provided with the operating mechanism;

Figure 3 is an enlarged sectional view taken on the line 3-3 of Figure 1;

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

Figure 5 1s an enlarged side elevational view of the shaft support shown in Figure 4.

Referring in detail to the drawings, the numeral I designates a roadway which may run in any direction as for example, east and west, or north and south. Supported in the ground is a vertically. disposed hollow post II, and a gate I2 is mounted for swinging movement about the vertically disposed post II. A pair of spaced parallel brackets I3 and I4 hingedly connect the gate I2 to the post I I and the position of the brackets I3 and I4 can be varied as desired in order to support gates of various sizes.

The present invention is directed to a device for automatically opening and closing the gate I2. Thus, an occupant of a vehicle or a person mounted on a horse can open the gate without alighting from the vehicle or without dismounting from the horse. Arranged in spaced parallel relation with respect to the post I I is a vertically disposed upright I and the gate I2 and the upright I5 are provided with a conventional coacting latch mechanism I6 which normally maintains the gate I2 locked when the gate I2 is in its closed position as shown in Figure 2.

Rotatably supported by the top of the post II is a first horizontally disposed shaft I1, and an 2 Claims. (01. s9- -51) actuating arm I8 is, connectedto the firstishaft I! by means of a pin I8, Figure 4. Connected to one end of the arm I8.is a pair of cables or lines 28, while connected to the other endyoi the arm I8 is a similar pair of cables or cords 2 I. The cables 28 and 2I extend parallel with the roadway I0 and are adapted to be grippedand I pulled by the user to rotate the arm I8 when the gate is to be opened or closed. .The cables 20 and 2I may have a counterweight connected-to their outer or free ends so that after the user has pulled on the cables to open the gate, the counterweights will return the gateto its normal 'or closed position. The shaft I'I projects'through an opening 22 in the post II, and a sleeve 23 is circumposed on the shaft H, the sleeve 23 serving to maintain the arm I8 in proper spaced relation. A washer 24 is circumposed on the shaft I1 and is arranged within the post I I. A bevel gear 25 is mounted on the inner end ofthe shaft I1 and is secured on'the latter by means of a pin 26. Arranged in meshing engagement with the bevel gear 25 is a second bevel gear 21 which is mounted on a second shaft 28. A pin 29 serves to maintain the bevelgear 2'I fixed on the shaft 28. Thus, upon rotation of the shaft H, the shaft 28 is caused to rotate since the gear 25 and gear 2'! are arranged in meshing engagement with each other. However,'-in place of using intermeshing gears for connecting the shafts together, other coupling means may be used, such as a universal joint, or a flexible shaft.

The shaft support 30 is provided for maintaining the shaft I1 and 28 in alignment and the shaft support 38 includes a pair of diverging socket members 3I and 32 which rotatably receive therein the inner ends of the shafts I! and 28 respectively. The support 38 is provided with a pair of interiorly threaded

recesses

33 and 33 which threadably receives therein set I screws 34, Figure 4, for maintaining the shaft support 30 immobile. Circumposed on the shaft 28 and arranged contiguous to the inner surface of the post II is a washer 35. A sector shaped plate 36 is arranged contiguous to the outer surface of the post II, and suitable securing elements, such as screws 31, secure the plate 36 to the post II. The plate 38 is provided with a plurality of spaced openings 38 therein for receiving and snugly holding

stop members

39 and 48, and the

stop members

39 and 48 can be positioned in any of the openings 38 desired in order to limit pivotal or swinging movement of the bar M. A pin 42 connects the bar M to the shaft 28, so that movement of the arm l8 causes the bar 4| also to move, the bar 4| beingarranged contiguous to and in sliding relation with respect to the plate 36.

The upper end of the bar 4| is provided with a plurality of spaced openings 42 which are adapted to selectively receive a wire hook 43 therein. Carried by the wire hook 43 is a pair of

cables

46 and 48, thecable 46 being connected to a springffl. 'j'llhejspring 41 is connected tothe slide bolt of thelatchlS, so thatrotation of the arm 4| disengages the slide bolt of the latch lfi v, I

to thereby permit the gate to be swung open.

The line or cable 48 is connected to a spring 49, and the spring 49 is connected to an eye bolt 50 which is connected or secured td the nd'ofth'e gate l2. Thus, movement of the bar;-4l ;.wi-1l h'e'ctin'g"said'gat'e to saiwpost, a vertically discause swinging movement of the gate l2 at the same time that the latch I6 is being opened.

A cap 5| is arrangedin threaded engagement i'wtih the' threadedzex-terior portion 52 ofthe post 2-:'||:to protect the inner working parts of :the gate iop'eliating mechanism from adverse weather coniqditions, such as'rain, dust, snow and thelike.
