To all: whom it mag concern Be it known thatI, JOHNv SPENCE, of the;

city of Lethbridgaa in the Province of Al-v bert'a', Canada, have invented certain newand useful Improvements" in Grate-@pening- Devices, of which the following is the speci-f fication.

My invention relatesto a device for open-o ing gates, and the object of the invention is? and durable deviceof this class. a

With the above object in view the 1nven-1 tion consists essentially in the arrangement and construction of parts hereinafter more! i particularly described and later pointed: out in the appended claims. a 1

Fig. 5 is an enlarged de-: tailed side view of the rollers carried by the top cross beam. Fig. 6 is al'sectional View; through the track secured to one of the fence boards. Fig- 7 is a sectional view; through the track carried by the spannen;

Inthe drawings like characters of refer-1 ence indicate corresponding parts in each figure. J a v 1 and 2 represent upright gate posts firmly embedded in the ground 3 andrcon: nected at the top by a spanner 4. j

end of the spanner andhaving the ends thereof supported by braces (ija-nd 7 which pass angularly between thecrossbeam and the post 1. a

8' represents afence post whichis con:- nected to the gate post by the usual fence boards 9.

10 is a gateformed from inner and outer upright end beams 11 and 12- connectedby cross bars 13. The beam 12 is considerably longer than the beam 11 and it is reinforced by an angularly disposed brace beam 14:,

15 is a track secured permanently to the upper of the fence boards 9, which track supports a roller 16 fastened to'the upper end of the upright beam 11. i

17 is. a track secured permanently to the spanner andsupporting a roller 18 carried by a special casting 18 tothe upper end of the upright beam 12. 'These rollers it will be seen support the gate so that it can be shifted backwardly and forwardly as desired. The casting '18 presents a sheath for the' roller 1 8 and is supplied at, the inner side-with two opposing lugs 18 and at the outer side with a single lug 18 19 is a locking bar pivotally secured by a pm 19 tothe lugs-18;, and having the free end more or less in theform of a spear point presenting notches. 20 and 21', The body. of

the locking. bar is. provided with an opening I i A 23 in which i-s-located a roller 24'. to provide an lnexpenslve, easily operated I 25 is a spring pressed latch pivotally faswardend designed to, pass over. a pin 2-7; se-

, cured to; the post 21 A is a ring located directly under the ;locking bar and; carried by two cables 28 and 29 which pass upgwardly through the open- ;i'ng 23 over the, roller 2 L around pulleys i 31 located on the underside of the; top; beam loafter which they, are passed in opposite directions, outw-ar ;ly over further pulleys 32 located at. the end of the cross beam 5.

The endsof the cables are supplied with hand, grips 3,4 respecti'trely, while weights 35 are tied tothem between the pulleys 32 andthe hand grips A wire 13 connectsthe ring A with ;j the spring. latch QbfThe ring A is supgplied large enough so that it will not. pass throughth'e opening 23 in the locking bar and it is positioned sufficiently far below the locking bar to-a'llow the cables to release t the spring latch 2 5gprior to, the ring. en 5' is a top beam secured centrally to one gaging with the locking bar; I

36 is a dividing plate appearingbetween the pulleys 31, 37 are short catch rods It will at this point be readily seen that if one pullson one o -other of the cables 28 or 29 he willfirst lift the latch 25 to release the gate and then he will swing the catch bar to one side" or other so the catch bar will lock the gate open as soon as it engages with one or other of the catch rods 37.

38 is a cable or rope tied to the lug 18 and passing over a pulley 39 carried by the post 3; The free endof said cable carries a weight 40 sufliciently heavy to draw the gate closed when the catch bar is released.

The operation of the attachment is 'now described assuming a person approaching the gate in a vehicle and that the gate is closed. At the time the driver comes within range ofthe piece he grabs it and pulls, which action causes the gate to be opened, the pulled cable initially raising the latch and finally drawing the gate over so that the locking bar engages with one of the catch pins. When this occurs the cable can be released as the gate is locked open and the vehicle can then pass through the gate opening. Upon reaching the opposite side bracket 41 to the base of the post 1. Two

stops 42 are also fastened to each side'of the post 2 and receive the outer end of the gate when it is closed assisting the latch in holding it firmly. What I claim as my invention is 1. The combination with a gate and tracks 'suppor'ting'the gate, of weighted means holding the gate'normally closed, hand grips connected to the gate and located at the approach to and beyond the same, and means for locking the gate in the open position,

said; latter means being set in'the locking position by a pull on the hand grip on the approaching side of the gate and released from the locking position by a pull on the hand grip located'beyond the gate, as and for thepurpose specified.

2. The combination with a gate, a track supporting one end of the gate and located at the end thereof, and an elevated track supporting the other end of the gate and located above the same, of weighted means designed to continuously close the gate, re-

leasable means for locking the gate in the open position, elevated hand grips at the approach to and beyond the gate, such hand grips being connected by cables with the locking means, said locking means being arranged to be set in the locking position by a pull on the hand grip on the approaching side of the gate and released by a pull on the hand grip beyond the gate, as and for the purpose specified.
