H. F. G UTH GATE 2 Shets-Sheet 1 Filed Aug- 15 1921 I Referring now more particularly to the v-meohanism permitting of an operation of I ing of the. ready. response the gate-withthe expenditure-of but a minimum of energy, it is my purpose to provide a panel and mounting. therefor, such gate panel. swinging in a vertical plane and being counter-balanced by a weight insurof the gate panel to but a slight impetus. This purpose is accomplished by mounting the panel and.

the counter-balancing weight therefor in such amanner that the panel when-intermeh ated to its fully open position.

This result is accomplished by pivotally securing,.in a manner hereafter more fully specified, the panel 11 to a pair of posts 12 .clearly shown in Figure 3. The panel. as will be noted, swings through a vertical plane and the outer end oi the same. is adapted to lie; in the closed position of the gate'adjacent a latch post 1.3. The gate in its closed position is held from movement withurespect to this latter post by virtue of latch 14 normally engaging the under side of a latch plate 15 by virtue of any suitable 7 type of spring 16 serving to'cause the for- 'm'er to normally lie in this position. A retraction of the latch 14 is conveniently effected by'a latch rod 17 passing through guide eyelets 18 provided for this purpose,

so that upon a pull being exerted upon. the

rod '17 aretraction of the latch 14 will result, permitting this ,member to clear. the latch plate 15.

Now with a view of providing suitable means which will serve, upon the gate being lowered, to guide the outer end of the same roper position, Y-shaped guide 1rons to its p are associated with the latch post 13. These irons conveniently comprise a Y-sh'aped body portion 19 provided with outwardly extending flange 20 adjacent their side edges. In this connection, it is to be noted that the uppermost of the guide irons conveniently terminates in the latch plate 15 so that asingle packed. unit may be provided.v .The lower guide iron is provided with i a stop 21 of any suitable character which is adapted to coact with a cushioning member such as a spring 22 positioned adjacent the outer end of the lower edge of the gate panel' 11. It will nowbe understood that upon the panel swinging downwardly, that the outerend of the same will be moved to its proper position should any slight mis hen moved past" thisesa-505 alignment of the operating parts of the same occur by virtue of the fact that the gate stud 23 associated withthe panel 11 will engage the outwardly extending flanges 20 oi; the body portion 19, upon the descent of the panel simultaneous with the engagement of the spring 22 with the guide iron provided for this purpose adjacent the lower end of the latch post 18, thus guiding the gate to a point at which the outer edge of the panel will be in perfect alignment, i, e., its proper position with respect to-the latch post 13. Upon the continuation of the downward swinging of the panel11, the latch 14 will. be retracted by virtue of the engagement of the spring 16 by the latch plate 15, subsequent to which the latch 14 will ride past the edge of the plate 15 and snap into the position indicated-in Figure 4, thus preventing any further motion on the part of the panel 11 with respectlto the fence. In this connection, it is to be'noted that the panel 11 will have to move with a relatively large amount of speed to overcome the retarding action incident to the operation of the latch 14, insuring that these parts will be in their proper position upon the completion of the movementof the panel. adjust the movements of the parts with that degree of niccty insuring this operation and an immediate stoppage of movement on the part ofthe panel; and with a view of cushioning any shocks incident to the closing of the panel 1.1, it will be noted that the spring 22 will coact with the stop 21 so that a cushioning action. will be set up, thus insuring a gradual braking of the movement of the panel without any danger of the parts of the gate becoming injured.

Necessarily, it will be impossible to i Now with a view of providing operating mechanism for a gate in such manner that it will be possible for an operator to actuate'the gate panel irrespective of which. side ota vehicle he may be occupying, suppleinent posts or stanchions 24 are provided,

one pair being conveniently locatedin ad.- vance of the gate and upon each'side of? the roadway, the second pair being in asimilar position to the rear of the gate, contrary to the conventional construction which provide single postin advance of the gate, a second post being positioned to the rear thereof. Associated with each of the supplemental posts 24 is handle 25, to which is conveniently connected a cable 26 extending over guide members 27 and having its inner end secured as at 28 to the panel 11. It is to be noted that a further cable or other suitable connecting member 29 has one of its ends secured to each of the cables I a pull in anrupward direction."

To now properly counter-balance-the panel 11 so as vto insure a ready response upon the part of the same, it'is now primarily to be noted that the pivotal con nection existing between the panel and the gate posts 12 is eifectedby providing a gate pivot clearly shown'in Figure 5, which piv- 0t preferably includes a rod 30 which has its ends rotatably housed in bearings of any suitable character 31, this rod being'secured to thegate panel 11 in any convenient man. ner. Bolts 32 pass one through each of the gate posts 12 and have their inner ends engaging and supporting the bearings 31. Springs 33 are conveniently interposed between the gate posts 12 and the outer, ends Of the bolts 32, thujs'retracting the'latter-to a position at which the pivot bearin'g'will be firmly held against the faces of the gate posts. a

It will be noted that thebolts 32 extend through the posts 12 at an angle and it will be understood that any jars incident to operation of the gate, even though the same may be somewhat unusual such as the slight collisionon the part of a vehicle and the gate panel, that the pivot thus provided will be capable of giving so that a movement of the panel may be effected with respect to thesupporting posts 12,-without any material injury of the gate resulting. I

Referring now more particularly toFigure 2 it will be seen that an actuating link 34 has one of its endspivotally secured adjacent thelower edge of the panel 11, its upper end being'pivotally associated with an actuating arm 35, which latter is rigidly aflixed to a pivot shaft 36 rotatably secured by means of any suitable type of bracket 37 to one of the posts 12. Associated with the opposite end of the shaft 36 is an arm 38, which latter is conveniently'slidably secured to the shaft 36 and is aflixed in any desir able position by any suitable means such as a set screw 39. By this latter construction, the length of the arm 38 may be varied and the leverage exerted by means of the weight 40, which is afiiXedto the outer end of the arm, may accordinglybe varied.

F or a purpose hereinafter more fully specified, a spring 41 is provided at a point directly below the outer end of the arm A pawl, more particularly shown in Figures 6 and 7 is associated with the outer end of the arm 38, which pawl may be of any convenient type such as a foot 42 p-ivotally secured as at 43 to the arm38 and provided of the operating parts with a'stop 4A, which permits ofthe swinging of the foot 42 in but one direction;

It is now to he noted that the actuating arm 35 is of less length than the distance betweenthe point of pivotal connection of the link 34' and panel, 11 and the pivot exist v ing between t'he gate post 12and the latter.

hus formed, the panel. 11;:swinging through an arc ofsubs'tantially ,Qi. e., to the position indicated in dottedlines in Figure, 2,"

at whichthe inner edge of the panel illseats upon the rest 45, the weight 4:0 aud ts associated arnr38 will-travel through an arc greater than 90, in other "words, to the*eX- treme. positionindicated .inxdotted lines in H Figure 2. It will readily -be.appreciated .that bythis construction when thefgate' is half way open, that it is perfectly balanced by the weight and will remain at rest at this point assuming thatthe length ofth arm 38 has been adjusted so that the proper leverage 1s. secured). If the gate is .now

given animpetus towards its closed or'low-- I ered position, it will continue to gain momentum untilit reaches this position and is locked by the, latch, the gUlClQuIIOlIS ins suring it proper position on the outer end ofthe gate. Ashas been afore described,

the spring 22 will reduce and gradually re-.- tard the momentum of the gate, so that any unusual ar incidentto the same reach ng its closed position is eliminated.

rissuming. aga1nthat the gate is half raised, i. e., in this balanced position, it will i be. appreciated, assiuning that an impetus in an upward direction s lmparted to the 100, panel .11, that by virtue of the arrangement of the actuating arm and pivotal mounting of v the ga'te, the"weight4l0 will actuate the same.

in such a manner that the niouientuln'of the panel "movement in' anupper direction is increased. Thus, the center position, ,i. e., the positionin which the parts perfectly counter-balance one another might be said to represent the dead center? position of the gate so that upon the panel 11 being moved through a vertical plane either upwardly or downwardly, this motion will be continued and accelerated to a point 'resulting in a complete opening or closing of the gate panel. As afore stated, the gate will now move-to its: fully open position and this motion will be continued and accelerated to a point at which the pawl associated with the outer end of the arm 38 strikes the spring 41 and it will be understood that by virtue of the frictional engagement incident upon this operation taking ef fect, the motion of the panel will-be retarded. Also, by reason of the arrangement ofthe spring 11, the outer end of the arm 38 will meet with increasing resistance to a point at which the motion of the arm and consequently the panel 11 are. nearly checked, .at which point the latter will be in almost its full position. Upon the arm reaching a point at which the momentum of position indicated in dottedlines in Figure '2, thus perfectly counter-balancing thepanel. and preventing any accidental closing of v the gate. 1

A'closing of the gate may now be effected by a second pull upon any of the cables 26, which pull in tiie nature of a jerk will inipart to the panelsutficient momentum to permit it reaching its 3 dead center position, below which point, as atore described, the closing will automatically continue. As

has been 'aforedescribed, the same pull or jerk when the gate has been closed will reverse the operation, with the exception that in addition to the movement of 'tlieparts described, the latch rod 17 will be actuated to eifectrelease of the latch 1e. Thus I have constructed a gate which i shall be extremely easy to operate-in that the parts are semieautoinatic in'operation,

the actuating means therefor being entirely accessible from any type ofvehicle or being capable of operation on the part ofa pedes trian from any number of different points.

It will further be. appreciated thatI have constructed a gate which is mounted in such 'a manner that, as afore described, the parts will always remain in alignment, not only upon receiving ars incident to normal op- 1118i plane of travel.
