This'inventionv relates to' gates, and nior'el particularly to an entrance gate for vehicles, inter'- posed yin the length of va fence', and a'dap'td'wtd be opened by contact with the bumper ofzan automobile -or other vehicles to open the saine when approaching in either'direotion, and to'delay-the closing thereof, so that the vehicle may clear the gate vbefore the latter closes,

An object of the invention is to provide novel means for mounting the gate and for releasing a springV catch` therefor normally engaged with a keeper when the' gate is in a closed position, and to release the catch by bumping engagement of an'Y autonobile or other vehicle with mechanis-rn on the" gate, and to further provide means for engagement with the gate and on said gate and a post disposed near the free end thereof when open, t delaythe closing of the gate.

Another objectof the invention is to provide a simple and novel means and construction for the above purpose, which is relatively simple, can be readily applied to a gate and which is not likely to get out of working order.

Other objects and advantagesreside in the details'of-'construction and operation as more fully hereinafter described and claimed,-reierence beinghad to the accompanyingdrawings forming part hereof, wherein like numerals refer to like parts throughout, and inA which: Y

Referring to the drawings' in dtail, the gate is`nteposed in` the linev of a fence at ailgalt opening-having a gateV supportingpost l5-` and akeeper supportingposti spaced therefrornfa suitable distanee according to the length ofthe gate. Both of theseposts may be reinforced by braces il Yand i3 as shown eitendi'ngat an angle from the posts near their upper ends ton the ground tor eie'etivel'y 'support the" posts in upright positions. The gate i9 is shown comprisin-gfa reetan'gular frame having a vertical hinge bar ne the hinged endV and anA outer vertical bar 2ly near the tree end, as distinguished from the inner or hinged' end, connected b-y horizontal upperand lowe'`bars 2L" and 23 An intermedia e oli-'third' horizontal bar 2li is provided bei. tiv'eeifi the vertical bars 2i! and '2l spacedabove the lowferfb'ar '2S-'and spaced a greater distance froni theotop'oriupper bar 22 and parallel theretol while anadditional vertical bar' is disposed near the free end'parallel to the bar'Zl' andloetiee'n theupper bar andthe bar 2Q, all: of saidbars'be'in'g"rigidly connected'or welded togethet as desired andv comprising tubular-Y* or other suitable4 itie'talrneinbersl In addition, wires or'cable'sfi" are esten-ded betweenthe bars fil andhorizontallyin parallel Yrelationand connected theretoVV through they medium of loops, u-bitsfor the like 2i, wane a brace 2s extends beneath Va web-or gusset plate 279 at the corner between the bars 2Q and 22,'and a similar gusset orwwehpiate atthe corner where the bars 24 andY 25 join'to prevent sagging of the gate.

bar"J 3T are 3 with the ends of the bar 31 and form receiving and retaining means for rubber or like cushions 4I which are retained in position at the ends 42 of the channels 4Q by means of bolts 43 imbedded in the rubber of the cushions or bars formed thereby and extending through apertures in the upper and lower ends of the channels. The channels may be of right angular or other shape,l as depicted in the Figures 1l and l2 of the drawings. the channels are rigidly. secured to the ends of the bar 31 extending cross-wise and :upon opposite sides of the connection of the arm 36 with the cross-bar 31, the latter is provided with flexible connections or chains 44 converging outwardly and connected to a similar exible member or chain 45 having its free end adjustably connected to a rod 46 as by means of a turnbuckle 41, one end of which is provided with a hook 48 connected to the chains 45 and the opp-osite end of which is provided with an eye connected to ,a loop 49 formed at the inner end of the rod 46 which isin turn connected at its outer end to a normally contracted coil spring 56 having its opposite or -outer end connected to the vertical post 2i as at 5I by means of loops, U-bolt and eye or otherwise in connection with a plug 52 on one of the links or loops 5l extending into the adjacent end of the coil spring G and locked thereto by a lug 53. A similar plug and

lug

52 and 53 respectively are provided between the rod 46-and the inner end of the spring 50 and an adjustable latch release bar 54 is secured to a U-bolt 55 and to the bar 46 and offset upwardly therefrom with means 5t for coupling the sections'thereof to render the same adjustable in length and the forwardly extending free end of the loop 55 in its projection in front of the bar 2| vertically at the free end of the gate.

`Inrorder to hingedly mount the gate, the inner end of the upper horizontal bar 22 of the frame I9 Aof the gate is internally threaded t0 receive a threaded shank 51 having a vertical openended sleeve 53 at its inner end receiving a pivot pin 59 therethrough. A collar 60 is clamped around the post I5 near its upper end and is split to provide a clamp having coacting apertured jaws V6I bolted to the post i5 as indicated at 62 as shown in Figures 1, 4 and 10 of the drawings. A horizontal plate 63 is welded or otherwise rigidly secured to the collar 60 and extends outwardly therefrom to a point adjacent the vertical bar 26 at the pivoted end of the gate. The plate 63 is provided with an elongated slot 64 near its inner end, in which the-pivot pin 59 is adjustably held on either side, by means of nuts 65 threaded on the pin 59 t0 clamp opposite sides 'of the plate 63, while adjustment is effected through the medium of a threaded stem 66 threaded through a threaded bore in the end of the plate 63 at its bight portion formed with the slot 54, said stem being in the form of a screw and held in adj-usted position by a nut 61 threaded thereon against the end of the plate 63 adjacent the threaded bore. In this way, the upper pivoted end of the gate may be held in adjusted position.

At its lower end, the post i 5 is provided with a similar collar 6o split and correspondingly held in Vposition on the post, the yparts thereof being correspondingly constructed and indicated by reference characters. A shorter fiat plate or arm 68, with respect to the plate 63, is provided upon the lower collar El) and carries a rigid vertical pivot pin 69 offset inwardly with respect to the At intermediate points of their length,

4 pivot pin 59. The pin 59 is engaged by a sleeve 16 forrnedv at the outer end of a threaded stem 1l loose in the inner end of the lower frame member or bar 23 and adapted to be clamped in adjusted position by a nut 12 engaged on the threaded shank or stern 1i against the inner end ci the smooth bored lower bar 23 projecting from the vertical bar 2Q and also adapted to be held by a set screw 13 threaded through the bar 23 in'engagement with the shank 1| as indicated in Figure 5 of the drawings. In this way, adjustment can be made without removing the pivot pin 69 as is the case with stem 51 which is of necessity threaded in bar 22 because the thrust is outward on account or theweight of the gate. The gate is adapted to swing on two pivots spaced horizontally from each other or off center, so as to tend to swing upwardly to an inclined position whereby it will return to a closed position by gravity under the weight thereof from an open position.

The lower pivot plate 34 may be connected at a point Yintermediate the two lower horizontal bars 23 and 25:1 by a wire rod or cable 14 to the vertical end bar 2l of the gate frame as indicated at 15 in such a manner as tc intersect the vertical bumper or cushion bars 4.-@ and 4l below the arm 36 and

chains

45 and 45. `'lhe length of the latter vertical bumper bars, provide means for engagement by the bumpersof automobiles or other vehicles at different heights, thereby insuring the actuation of the catch releasing mechanisrn. The latch bar 16 has a cross-bar 16 and is pivoted at 11 t0 a bracket 18 co-mprising spaced ears of U-shaped formation rigidly welded or secured to the vertical bar 2 l, with its long arm extending downwardly and a short arm extending upwardly. The lower end of the latch bar 16 is engaged by the release loop 55 of release bar or arm 54 and is normally held outwardly by la spring or other resilient means 19 inter- Y posed between the latch bar 16 and the vertical bar 2l. The pivotal movement of the bar 16 is limited by an adjustable stop member shown in the form of a threaded screw 86 adjustable through the upper end of the latch bar 1S and adapted to be held by a nut 8! threaded thereon,

in engagement with the front of the bar 2|.

The latch bar 16 is adapted tc engage a keeper consisting of a collar B2 of the same construction asthe collars Sii and similarly clamped'thereon at the post i t with which the free end of the gate cooperates. An inwardly extending plate 63 is rigidly secured 'to the collar. 82 by welding or otherwise and has pivoted thereon keepers Bt as indicated at on opposite sides and having eX- tensions et forming handles by which they may be hand operated. The spaced heads of the latchesV Se cooperate to receive the latch bar 16 therebetween and have bevelled outer edges 81, to permit autcmatic engagement of the latch bar 16 therewith in either direction when closing from an open position at either side ofthe post l5. The latches 35i are provided with apertured lugs 88 connected by a spring 89 so as to permit movement of the latches in either'direction in permitting engagement and Vdisengagement of the latch bar therewith. This is facilitated by spacing the inner sides or edges of the latches 84 as indicated at Se, it being understood that the lower endof the latch bar-1S at its point of engagement by the arm 5ft is received within the loop 55 formed at the free-end of the arm 54 as shown in Figure 7 of the drawings, so that when the bumper of a car strikes the vertical bumpi assegno? Ti to disengage the latch bar frornfthe'keepers- 8s* 4while exp anding' the `vspring 501- and compress spring le, andi-upon'y release thereof, permitting the springiito contractand provide aforce to swing'the gate open'when" the latch is disengagedbyv a push by an automobile;*which` should bein low gear.

More push or thrust' is notY necessary after vthe latch` releases. When the gate closes, the latch bar 'i5 under the action of its spring |0`will` again engage the keepers. This action is automatic upon the closing of vthe gate from either side, upon being swung to an open position at either side by reason of the opposite projection of the bumper bars from the opposite sides of the gates. Thisv action. isA also, facilitated by reason of the pivotal" mounting of the horizontal arm or bar St. on which the bumper bars are provided.

In order to momentarily hold. the gate in an open position at either side and delay the closing thereof, to` permit the clearance of the automobile or other vehicle after having passed through the gate opening and opening the gate as. described, Va third post 9| is disposed upon opposite sides of the gate post l5 and offset outwardly therefrom at either side, one of said posts being shown in Figure'Zv of' theV drawings at a proper distance from the gatev post l5 and related' and. pivoted. tothe adjacent portion of thehorir zontal bar Y2d as indicated at 91 toswing laterally on said pivot or rigid therewith if desired, asV The cylinder' shown' in Figure 6 of the drawings. EltisV provided' withY a bypass'Y 03" connected to opposite' ends 'ofthe' 'cylinder internally andv havingfa Vcontrolled'needle 'valve'gil' at one end vto regulate the fl'ow of' the oil or other fluid contained within the cylinder, from one end of the cylinder to the other. A piston operates in the cylinder 96 and its rod |0| passes through a packing gland |02 and nut |03 on the piston rod at the head or top end of the cylinder and carries a U-shaped yoke or fork |04 adjustably on its upper end in which a pair of upper and lower spaced' rollers |05 are journaled on horizontal shafts having bearings in the tines or vertical legs of the yoke or fork |04.

Also piston |00 is provided with holes |00' which are drilled through it between the center and outside circumference and which are covered at the lower end of the piston by a disc or valve |0I which unseats downwardly and lets the uid pass through holes |00 allowing the piston to move upward quickly when upper roller |05 Latc'hes 8'@ are limitedk intheir move4 mentsoutwardlyl away'irornl veach other'on pivots' 6, strikes arm 55. andy leaves only the bypass @d for the duid to-pass through as the piston comes down thus allowing the piston` to move downward very slowly. The vpiston rod it! does not pass through the lpiston but is screwed into it only a short way and is secured bya lock or jam nut |02.

rEhe disc or valve is heldin place by a small screw Iii through the middle but which is of just Ythe right longth'to all-ow the disc to drop away from the piston slightly as the piston rnoves upward thus allowing the fluid to through the piston instead of or in addition to the bypass 00. Thus, no rings or packingare needed on the piston because the iluid furnishes all the seal that is necessary between the piston and the cyl-- cushioning means determinedlby theJ/o'luineffof# fluid passing throughl the holes orpassagesliii'f as disc or valve 10i uncovers holes let' ward movements or reciproca-tion of the piston iilii within the cylinder ed whenthe holes- Veld TheY inclinedL track or are closedv by disc mi.

arm 93 is adapted to singularly eetweenf rollers lde'when the gato is swung to an open position toward the post Eiifat eithersideof the gate openingk and raiser they piston |05 within the cylinder 0e, so that its downwardmovement along the inclined trackl as the rollers |05 move thereon, will be retarded by the-fluidL within the cylinder to momentarily'd'elay'and ree'- tard the closing of the'gate when in anopenYV position, so that the vehicle may pass therethrough without obstruction and clear the gate before the latter olfses. This action isautomatic, since the rollers |635 are so positioned as to' be engaged by the inclined'track or rod assistedV by the horizontal or upturned portion 95 andthe spacing of the rollers |95 a greater distance than the thickness of the track 93 as particularly shown inY Figures 3 and' 6 of the'drawings, while the rollers are guided by llhe trackways'iormed' by the vert'cal channels il?? on the pests 2| andy 25, intheir reciprocating or up and down movements when actuated in the manner justA den scribed..

Thus, with the gate closed and the latch 'bar' i6 engaged with keepers S6, between the spaced inner edges thereof, when bumper of the automobile strikes the cushion bars ffii, the latter' willbe swung to one .side or the other and swing-the cross-bar Sil' on its pivot. By reason of the connection of the cross-arm or lever formed' by the bar 3'? through the chains id and d5, providing a flexible connection with the latch rclease arm 513 and loop or Ubolt 55 which engages the lower end of the latch bar le, the latter is moved inwardly on its pivot 'il to disengage the latch bar le from the keepers 8K1 and permit the gate to open under further impact. Inasmuch as the hinge pins or pivots of the gate are spaced horizontally or ofi center and the lower pivot is xed while the upper pin is adjustable, the gate will tend to swing to an inclined position so that it will automatically return to a closed position by gravity. As the gate swings to an open position toward one of the posts 0 i, the inclined track 03 will engage between the rollers |05 and elevate the piston. In the closing of the gate, the

The disc`v |01" seats upwardly and" through the ductv or bypass 9S; during' the dow-ner movement of the gate to a closed position willl be momentarily restrained or retarded by the piston o-r hydraulic retarding means, so that the vehicles can clear the gate opening and the gate before the latter closes. Upon the gate swinging to a closed position, the latch bar 'i6 will automatically move between the keepers 84 and be held in a closed position.

In View of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and d scribed a preferred embdiment oi invention the same is susceptible to certain changes iully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

What I claim is:

1. In a gate, a gate post, a gate hinged to said post, a keeper member suitably supported adja cent the free Vend of the gate and comprising a collar adapted to be clamped to a gate post and its pivot and having a resilient connection with` the free end of the gate to normally heid the cross bar at right angles to the length ci the gate, a pivoted latch bar extending vertically of the free end of the gate, means t0 adjust and limit the movement oi the latch bar, said latch t bar being engageable between the keepers and a loop at the free end of the release bar to engage around the lower end of the latch bar to disengage the latter from the keepers upon im pact with an impact member and swinging of the cross bar.

2. In a gate, a gate suitably hinged, a post supported at a distance from the gate equal to the length of the gate, a rigid inclined track carried by said post, a cylinder mounted vertically on the gate near its free end, a piston operating in said cylinder, a bypass connecting opposite ends of the cylinder, said piston having a rod operating through the upper end of the cylinder,

spaced rollers mounted on the upper end of theV piston rod adapted to be engaged by said track to raise the piston when the gate is opened and tracks mounted on the gate guiding said rollers up and down in the openinDV and closing movements of the gate, said therethrough to permit quick opening of the gate and to retard the closing of the gate to cause slow closing thereof.

3. In a gate, a post, a gate comprising a frame hinged to the post, a second post, keepers carried by the second post, a latch bar pivoted on the free end of the gate to engage said keepers, said gate having horizontal members between the hinged and free ends thereof forming part of the gate frame, a horizontal bar pivoted to the hinged end of the gate, a cross bar pivoted intermediately to said horizontal bar at its inner end intermediate the length of the gate, vertical cushion members mounted on the ends of said cross bar and projecting from either side of the gate, adapted to cause swinging of the cross bar upon impact of an automobile bumper or vehicle therewith, a release arm projecting from the free end of a gate and looped around the lower end of the latch bar, means normally projecting the free end of the release arm from the free end of the gate, and adjustable exible connections between said release arm and the cross bar upon opposite sides of the pivot thereof to cause retraction of the release arm upon pivotal movement of the cross arm to disengage the latch bar from the keepers, whereby further impact with the cushion members will cause opening of the gate.
