I ROADWAY earn.
Application jalea August eo, l1920. serial No. 406,942.
To' all 'whom t may concern.'
Be itjlrnown thatjLdAooe HAnsnN,a citizen orf the United States, residing at New York city, New` York, haue invented certain new Aand useful, Improvements Iin Roadway Gates,1of which thefollovring' isa clear, full, and exact description.` i
' lll/ly invention relateslto gates and more especially to those gates adapted tobe moved acrossav roadway to-,temporarily prevent passage oftraflic, moreespecially vehicles,
and an object of my invention is to improve the, construction ofzgates of this character V.whereby they are` rendered safer. 115
@ther -objects and Aimportant features will become apparent from the following` detaileddescription and claims when taken in connection with the accompanying draw 1- ings, in Which- Fig.` 1 isi-asidey elevation of af portion of a gate showing electrically controlled means therefor;
Fig. 2 is asirnilaryieu showing pneugrnatic means -for controlling` the this view` also showing .the outorfendofthegate Eig. 3 is a view similar to Fig. 2 but show- `engagedby a suitable keeper;
the Vpartsin a different position; l. f Fig". .et is .broken planyiew showing the manner of connectng; they cable to the gate ,structure; and 4 A y, Fig. 5V isaldetailof the keeper.
It has been customary lt )pr'ov'idei vertically swinginlrgates to temporarily block traflioat roadways, especially at railway 'crossings and these gates hayeusuallycomlp rised one or more 'piyotedinemhers adapt ed to he operated by 'powermeans usually pneumatic. the atesvbeing balanced so that they mayjrather easily be swung from closed .to open'position, or`.v1ce versa When in Yclosed positionathe? merely extends across the roadway` but if a vehicle runs finto such a gate, there is -`@great4 danger of theigate lifting` and permitting: theV vehicletopass under it.,` ,lMy invention directed Yso more lpartijcularly'- tof a grate structure Vin .-Whicht-he grate is locltedli'n Vclosedposition so that it would be almostiinpossible for a vehicle to --lorealrl through, even should y accidentally run the gate. It is obvious thatthe kindV of -poyver employed is immaterial, and in ztheparticnlar,embodiment of my invention lpghave shown a gate operated `both hy electrical and luy-pneumatic power.
.Referring to. the draWings, Fig. 1 indicates my improved gate operated electrically'. ln this form of device, a support 1 provided which may form the fulcruiin for the gate and may also provide a housing for the motoil 2, which motor is adapted to move the gate by means of a beveled pinion 3 connected to the motor shaft 4.-, said pinion cngjapjing beveled gear 5 mounted on a shaft 6, which carries a Worm .7 engaging a sector` 8 forming' part of, or rigidly attached tothe ,frate 9, said gate'pivoting'about a Vfulcrum 10. rEhe motor is adapted to be run in either direction and, `as will be readily seen, movement thereof in one-.direction will act to move the gate from closed position indicated in Fi 1 to open position. rlhe motor is supplied- With current `from line Wires 1l and 12 under control.l of a switch indicated atfl, the circuits being indicated diagrainniatically in the figure.
When the 'switch 13 is in full line position,
' .which is that shown in Fig. 1, current Will flow through the Wire 12 to the Wire 14, through the field magnet of the motor, through `Wire liandback through the switch to the Wire 11; Current Will also flow throunhthe ivire 1G to the motor armature,
returning; through the Wire 17 to theother the keeper between it and the hook when the gate is closed, so that When'the lock is in operative position it will be impossible to raise the .frate until the bolt'is again released. lirclerahly l control the bolt auto- `matically in .such amanner that it is moved to locking position as the gate reaches closed. position. and I also preferably'provide nleans whereby the holt is released concomitantly *with the Startin of the openingr movement ofthe `gatefln order to control the lock in the device illustrated inhig. V1, Whereinfthe gate is shown as electrically controlled, theA bolt 21 is connected to the core 22 of a solenoid 23. Mounted in alignment with this solenoid 23 is a second solenoid24, the core 22 being common to both solenoids. As the gate movesV to closed position, af contact 25 on the sector S makes Contact at 26 so that a circuit is closed through the solenoid 22, the circuit tiowing' troni the Wire 1 2, through the Wire 14, to the point 27. Yifi-oni this point the current flows through the wire 28 and the Wire 29 to the contact 25, to the Contact 26, Wire 80, through solenoid 22, retui'iiing` to the other side of the line through the Wire 31.
FifergrizationA othe solenoid 122 results in shooting the bolt to positiouto loc t the gate aiidth'is occurs just as Vthe gate reaches closed position, the hoolt 2O having' passed throuiih the keeper 18, as illustrated in Fig. 2. Vihen the sivitch 13is inoved to dotted line position shown in lig.V l, so as to reversethe V(flirection oit 4cuarent passing through the ii'iotor, current Will also beV suppliedgto the solenoid'l., and under these` conditions current rivill liioiv trein the wire to thepivire 32, togthe point 53, through Wire 345,'to solenoid 2l; returning,r through Wire to the point 36, through the switch, to p int? and back to the o thrrI side of the line.` The bolt will theretoie be .released dueto,'energiiatioii of the solenoid 24 coneoni-itantly with the supplying' of current i to the rnotor to raise tlie Lgat@ ln the forni of device shown in ligzjsl 2 and 3, the isoperated by air pressure. andV in this rtorni ot device l have also utilized the air pressure to operate the bolt, both to lock and Vto unlock the saine. ln this torin v"l-f" fl'l l "V l'lQl v"l vorc ei ice. a uic piessuie cy int ei et, unie i maybe of usuali construction, inay pro- :vided vvitliin the housing 1, said cylinder having a piston which inay he c(iunectedV With a rack 39 engaging a toothed wheel. 4.-() carried .by the gate, which is pivoted 'at'.vftl.. Fluid pressure is suppliedto the cyliiulerT 38*l hy ineansot pipes 42 and 43. Thesepipes inav lead to an Vau' pump or to -any suitable source Vot 'l'liiid supply. Vln Fig. 2 ytheparts vare shown in the position Y they occupy when the gate is closed and locked. With the parts in this position, therefore, the first thing to be done is to releasethe lock, ,and this is accomplished by admitting Kfluid vpressure `to the rightA side of a fluid pressure cylinder 44 mounted on the Q;ate, saidcylinder having, a piston tol ivhichlis connected the holt. 21. An
air` supplyl pipe- 11G leads from the cylinder onA the rinfht side of the 'piston to a diaphragnied chamber 1LT. The 'pipe 413 also leadsinto this chamber and opening' from Vit is a pipe 18 supplying' fluid pressure to 'the cylinder above the piston. '.llhereloi'e7 ivhenair or other fluid isradinitted to the Ipipe 411B, it passes into thediaphragm chainber .117 and thence tothe pipes 4G and 48, actuatingthe bolt 21 and Aalso supplying "tluid pressure to the cylinder 38 yto move 'the gate to open; position. l
ln order that the bolt inay be moved to i/ieeavi Y im thei'noveinent of the gate to opened position'.`
When the valve is in the position indicated in Fig. 3, passageway from' the chamber '56 to a pipe 57 leadingto the other end of the cylinder 4A is closed. l/Vhen 4it is desiredto close the gate,` fluid pressure fis admitted th rough the :pipe d2 and enters the chamber 56. A pipe 58 leads from the chamber V56 Y to the loiver portion of the cylindergso that when the pipe l2 iszo'peneth'tluidjpressure enters the underside of the piston in the cylinder SS'raisingthe same and causing the gate to lower. VSince the passageway to the pipe 57 is elosedby the valveflQ', as indicated in 3, no `tluid pressure will be supplied at this time to the cylinder 14, and
therefore the `bolt will remain inoperative. However, aszthe gate reaches closed posi# tion, the pin 52 bears on the. earn edge 59 of a-,canilever 6 0, said leverat its other end engaginga pinl'on thelever', thisfent Y gageinentwresulting inthe rocking vet said i'e'ver and moving the valve 49V from' lthe position shown in Figto thatshoyvn in Fig. 2, thereby permitting the fluid pressure in the chamber 56 to il'oiv through the pipe 57 and into the cylinderlld at its. lef't'tviiandend,
outto the position shown in Fig. 2, thereby locking the'gateto the keepeu In bothfconstructions described, the bolt is moved "to locking positionas the gate reachescclosed position,- and asthe power1 is applied to inove as shoivnfcin Fig. 2. Theholt is then shotf ilo the gate, the bolt is autoni iticallyreleased.V 'i Since the framework otgates oi this general character is made comparatively light and would not be suiiicientlystrong to resist breaking WheninV locked position if .struck by a vehicle `at tiers-time, in order tov strengthen the gate and to vprevent ac-vehicle from breaking it andpassing through the 4fate in case lit should accidentally strike it', l provide a cable indicated at 6 J.l`his cable has its'ends Vfastened into screw 'eyes Y Gil whichscreiv-eyes are connected to across piece 65 forming. the end of a sleeve 'nieni- 1 ber 66, this member engagingoveran en-V 1arge`d .portion 67 connected totheibolt. A

VWhile I haveshown at least two practical embodiments of my invention, it is of course to be understood that various other forms maybe used within the spirit of the inyention and that some of the parts Vmay beused without others. i
