GATE.

Application filed June 15, 1925, Serialy No.' 37,282, and in' Canada'irune 8, 1925.

This invention relates toy improvements'in gates, particularlycollapsible gates, Which may be operatedfrom these'at of a vehicle avoiding the necessity of dismounting there-- from. v

Further Y objects" aref to provide aA gate of simpleVIA and durable construction and easilyV operable.

With-'this and other objects iny view, the invention consists essentially ofthe combina# tion andiarrangement of par-ts 'hereinafter more fully described in the accompanying 'spfeccation and'dravvings, in which :y

Referring rnowV tothe drawings,I A indi#v cates the gate asa wholeiaiid comprises prin# cipally l posts* B and@ adjacent onefanother with the gate-operating mechanism D mount ed' therebetween. E indicates a single post placedl at a suitable 'distance' froml theposts B' and' C and connected thereto by the-gateforming chainl 10, thee'nds 11 of' which ,are connected' in any well-known manner to` the post EL Mounted on,k theinside 'of the posts B and; C are U-shaped' guidewaysorchannel members 12v in which the gate-operating mechanism D is adapted to travel.` This mechanism comprises an arm 13 pivotally mounted at 14. Secured to and extending frointhe upper extremity of the'1nember`13 are the links 16 and 17 pivotally mountedat 19 and 2O respectively, the link 17 being provided with a latch-operating pin or the like 21and is connected to a rod 22 to'which'in turn is connected at 23 cables 24 and 25. The cables 24'and 25 are adapted to extend over the pulleys 26 and 27 suitably mounted adjacent the top of the posts B' and C and extend from the posts 'a suitable distance, where they may be conveniently operated. The member 13 is suitably bent' at 13a and is provided with a pin 18,j another pin 20EL being provided on the link 17, both pins being designed tolimitthe closing movement of the members 13 and 17. v

Pivotally mounted on the arm 13 at 28is aninverte-d U-'shaped member 29l in" which' is supported by the shaftv 30l a sheave`v or groovedA roller 311. The upper or lead chain; 32, herelsho'w-n as"- an extension of the gate 10",?'may beseparate therefrom and securedthereto inl any" suitable manner. This lead chain is designedto travel over the grooved pulley 31 and to be suitablyanchored 'atits looseend to'the gate post B as lat"33f 1t will also be'noted that the pulley for the lead chain'is arranged adjacent thereto and preferably thereabove soy that' the leady lchain will be at an angle' to the top of thegate;

This construction, comprising the lead chain for the top of the gate adapted to'travel'over a movable pulley adjacent to and above the gate andto be anchored securely at its loose end, is'an essential and important feature of our invention. The shaft 30 of the sheave 31 is provided with rollers 36adapt`e'd on the operation of the gate vmechanism tov travel up and down in the guideways 12.'

Directly above the roller 31, as particularly illustratedV in Figure 5, is mounted between the posts B and C the shaft 37. On this shaft is the trip and lock'mechanism F. The lock member F is provided with a lip or eX- tension 38 which is designed to engage with the lupper extremity of the inverted U-,shaped member 29. lllxtendingr rearwardly and sloping downwardlyfrom the body vportion ofthe locky are the' engaofing hooks 39. As illustrated in Figure 1, tnese are adapted to form a substantially V-shaped slot 40 which permits the upward ordownward operation l of the member 17 therebetween. j

In operation, by'a pulll on either loable 24 or 25V the pin 21' engaging the hook meml bers 39 will cause the lip 38 to become disengaged from the member 29. The cable is then released and the gate 10 will by its own weight' drop to the ground'. as indicated by dot-ted lilies in Figure 1, the sheave 31 travelling downwardly in the guideways 12 permitting the chain gate 10 to assume that position; After a vehicle has passed over the gate on the ground, theother cabler is then' pulled causing` the .gate-operating mechanism D to be raised, the lip 38 engaging the U-shaped member 29 and retaining it in that position. It. should be noted here that as the mechanism for operating thegate is being raised, the pin 2l does not engage the hook members 39. Alter the lock F has Vengaged the member 29 and the pull has been released on the cable, the link l? which has in the operative pull been allowed to pass freely over these engaging members, will drop into normal releasing position as indicated in Figures l and 5; the gate is then closed and in a position to be operated further. y y i As many changes could be made in the above construction and many apparently widely dillerent embodiments of our invention,Y within the scope ot the claims, con* structed without departing from the spirit or scope tliereoii,'itis intended that all matter contained in the accompanying specification and drawings shall be interpretedv as illustrative and not in a limiting sense.
