GATE.

Application filed September 11, 1922. Serial No. 587,625.

To all whom/15 may concern j Be it known that I, JOHN MoCoRMroK. a citizen of the Dominion of Canada, and resident of Ottawa, in the county of Carleton and Province of Ontario, Dominion of Y Canada, have invented certain new and use ful Improvements in Gates, of which the fol* lowing is a specification.

This invention has rela-tion to certain new anduseful improvements in gate structures and has for its primary object the provision of a gate structure which will be of simple and inexpensive construction and which may bc readily opened, if desired, from a distance thereof.

The invention has for another object the provision of a gate which will be automatically locked when closed but which may be readily unlocked or unlatched and opened by the operation of a single rock shaft controlled by levers on opposite ends thereof at a considerable distance from either side of the gate. j

A further object of the invention resides inthe provision of a gate of the character stated, which willv be of such construction that the longitudinal bars thereof will swing on their rear ends and move toward and away from one another at their forward ends as the gate is opened and closed.

The invention has for a further object the provision of a gate of the character stated in which will be included a novel form of latch releasing mechanism connected with and controlled bythe rock shaftcarrying the gate lifting'or opening members, so that the gate latch will be thrown into inoperative position at the beginning of the operation `of the. rock shaft which opens the gate. 1

The invention has for a still further object the provision of a gate of the character set forth, which will be composed of the minimum number of parts of simple and inexpensive construction yan arrangement, which will be strong andsubstantial, highly efficient in use and which will include a the gate.y

when approaching the gate from either side Y balancing member' adjustably mounted on- Vith the foregoingjand other objects in view, ceeds as will appear as the description prothe invention consists inthe novel construction, combination and arrangement of co-operating elements as hereinafter more specifically set forth, claimed and shown in t-he accompanying drawings forming a part of the present application, in which:

Fig. 1 is an elevation of the improved gate in closed position, the gate being indicated in partially open position by dott-ed lines.

Fig. 2 is a plan view of the gate in closed position.

Referring more in det-ail to the drawings, 1n which similar reference characters design ate corresponding parts throughout the several views, 5 indicates the latch carrying g and carries the link 6 which is of substanf ate post which is slotted longitudinally tially U-shaped form and pivotally mounted e at the free ends of its legs on the pivot mem- `lower inwardly directed end ofthe depending` latch member 8 engages upon the upper face of the projecting forward end 9 of one of .th

the central bar, as shown in Fig. 1.

e longitudinal gate bars 10, preferably The projecting forward end 9 of this longitudilatch `nal gate bar 10 extends through the latch carrying gate closed position.

A' substantially 11 is post 5 when the gate is in U-shaped bracing member extendedover theupper portion of the carrying gate post 5 and mounted on 1 the pivot. members 12 on opposite sides thereof. It will therefore be seen that while the substantially U-shaped bracing member 11 serves to brace the latch carrying gate post will not interfere with opening and closing of the gate, as the substantially U-shaped bracingmember 11 may be turned away from the lugs.'

gate, as shown in the drawe gate' post lf3' is at the other side of the gate opening and is anchored in upright position, as will be seen by referring to Fig. 1. The inclined gate carrying post 1-1 is connected at its upper end to the upright gate post 13, as shown in the drawings and ext-ends downwardly and forwardly from one side thereof, as will be readily understood by referring to Fie'. 1. The inclined gate carrying post 14 is formed of parallel spaced members vconnected at their upper ends by the connecting bolt 15.

The connecting members 16 extended through the forward end of the horizontal post bracing member 17 arealso extended through the lower portions of the spaced members forming'the inclined gate carrying post 1i. Suitable connecting members 18 are passed through the rear end `of the horizontal post bracing-member 17 and into the lower portion of the gate post 13, as shown, clearly in `Fig. 1. It is therefore evident that th'ehhorizontal post bracing member 17 serves to connect and rmly brace the gate post l?) and the inclined gate carrying post 14.

The several longitudinal gate bars are mounted on their/rcspectiye pivot bolts 19 which extend through the rear ends of the longitudinal gate bars 10 and through the spaced members of the inclined gate carry- 'ing post 111 to permit the longitudinal gate bars V10 to swing in a vertical plan from the inclinedgate carrying post 14. The several longitudinal gate bars 10 are connected near their forward ends by the parallel connecting bars 20 positioned on opposite sides of the. gate and extending downwardly and forwardly with the lower ends of said parallel connecting bars 2O `depending below the bottom or lowermost longitudinal gate bar 10. Pivot bolts 21 are extended through the parallel connecting bars 20 andthrough the respective longitudinal gate bars 10, as shown inthe drawings. By referring to Fig. 1. it'will be evident that the parallel connecting bars 20 permit the longitudinal l gate bars 10 to swingfreely on their respective pivot bolts 19 and as the gate swings upwardly, the forward free ends of the longitudinal gate bars 10 will move closer toether, as indicated by dotted lines.

The reinforcing plates 22 are `secured upon the sides ofthe lowermost longitudinalgate bar 10 at the rear end thereof, as shown clearly in Fig. 1. `Similar reinforcing plates 23 are secured on the sides of the uppermost longitudinal `gate bar 10 and mountedV on; the gate operating shaft 24 extended transversely through vthe inclined gate-carrying post '14 in lplace of a pivot bolt 19 for this uppermost longitudinal gate bar 10. y Therear end of the uppermost longitudinal gate'bar 10 is cut away, as shown in Fig. 1 and the v purpose of which will presently appear.

By referring to Fig. 2, it will be seen that the gate operating shaft 24 extends for some distance to either side of the gate and then Iterminates in downwardly directed operat ing ends 25. It will also be seen by referring to Fig. 2 that the reinforcing plates 23 have their main portions offset outwardly from the sides of the longitudinal gate bars 10 and positioned outwardly of the sides of the inclinedgate carrying post 14. This is also true of the reinforcing plates 22, as shown in Fig. 2.

Rigidly mounted on the centre of the gate yoperating shaft'24t is the upwardly and rearwardly directed lever arm 26, to the upper end of which i'spivotally connected one end of therod 27,`the other or forward end of which is pivotally connected to the upper end of the latch releasing linger 28. This latch releasing finger 28 is mounted on the pivot bolt 29 provided 'therefor in the 'forward end portion of the uppermost longitudinal gate bar 10, while the downwardly and outwardly directed lower end 30of the latch releasing fingerv 28 worlts freely through the latch vcarrying gate post 5. This downwardly and `outwardlydirected lower end 30 of the latch 'releasing finger 28 engages the inner side ofthe depending latchfmember 8 to force the same outwardly to inoperative position and release the ygate when the latch releasing finger'28 isfoperated through the medium of the rod 27 and upwardly and rearwardly directed lever arm 2G when the .gate operating shaft 24: is turned in one direction.

Rigidly mounted on the gate operating shaft 24E, outwardly of the sides of the inclined gate carrying post 14 and adjacent thel latter,.-are the gate raisingmembers 31 which are inclined doivnwardly and `forwardly and then extended forwardly in a Ahorizontal plane. as shown clearly in Fig. 1.

Thesegate raising members `terminate in turned 'forward free ends directed toward one another and extending` beneath vthe-reinforcing plates 23 and normally spaced slightly below the same.

lVhen turning ofthe .gate operating shaft 211 is continued after lthe releasing of `the depending latch member 8` from the gate, theturned forward free ends 82 of the 'gate raising members 31 will contact with the reinforcing plates 23 and raise the 'gate to open position byrswinging the longitudinal gate bars10 upwardly on their pivotally mounted rear ends. This maybe readily understood'by reference to Fig. 1. in which the gate is shown by dotted lines in partially 'open position.

Tn order that the gate may be properly balanced at allt'imes andl opening and closing 'thereof more readily accomplished, a counterbalanoing weight 33 is employed. This counterbalancing weight 33 is adjustlll) ably "mounted between the extended rear ends of the longitudinally slotted weight supporting bars 53a by means of the mounting members adapted to be secured in adjusted position along the slots of the -longitudinally slotted weight supporting bars 231i. y

One of the central or inner longitudinal gate bars 'l0 carries the longitudinally slotted weight supporting bars 34 which are slidablymounted on the pivot bolt 19 for said longitudinal gate bar l() and a clamp ing` nut 3G is employed on an additional guide bolt 37 projecting from one side of the said longitudinal gate bar lO and through the slots of the longitudinally slotted weight supporting bars Se, so that the latter may be securely fastened in adjusted position hingitudinally of the longitudinal gate bar l0.

It is evident that a line adjustment of the (.:ounterbalancing weight 38 on the gate may be accomplished by adjustment of the counterbalancing weight 323 on the longitudinally slotted weight supporting bars 34: and also adjustment of the latter on the longitudinal gate bar l supporting the same, Downward swinging movement of the gate is limited by means of a stop block 38 within the latch carrying gate post 5.

From the foregoing pay 1agraphs taken in connection with the accompanying drawings, the complete construction and operation should be apparent. It may be briefly stated, however, that Whenever the gate is closed7 the depending latch member 8 will automatically engage the projecting forward end 9 of one of the longitudinal gate bars 10 and lock or latch the gate in closed position; as shown in F l.

lllhenever it is desired to open the gate when approaching the same from either direction; the downwardly directed operating end Q5 of lthe gate operating shaft 24 on this side of the gate is grasped and the gate operatingY shaft 24 rotated or turned in the proper direction to draw back thevupwardly and rearwardly directed lever arm 26 and actuate the latch releasing finger 28 to disengage the dependinglatch member 8 and swing the saine together with its link 6 on the pivot members 7 until the depending operating ends and as the gate closes, the depending latch member 8 will automatically catch upon the projecting forward end 9 of one of the longitudinal gate'bars l() and again latch or lock the gate in closed position. l

lVhile the preferred embodiment of the intention has been disclosed, it is to be understood that minor changes in the details of construction, combination and arrangement of co-operating elements may be resorted to within the scope of what is claimed without departing from the spirit of the invention.
