To all whom it may concern:

Be it Known that l, YOSHIMASA Masozswa,

a snbj set or": the Mikado of lapan, anda resi dent of l irmona, in the county of Kings and State of Calii'ornia, have invented certain new and useful improvements in Swinging Gates, of which the following is a specification.

My invention relates to swinging gates and has for its object the-provision of a gate operating means comprising a gate mechanism, operated by the wheelsof vehicles appreaching the gate, to open the gate away from the vehicles and to hold it in a latched position until the vehicle has oassed through the gate, when the latch may be released by the wheels of the departing vehicle and the gate is returned to its closed position by a weight. A latch is alsoprovided for the gate in its closed position that'is operated by the gate swinging mechanism.

ltly invention will be described in detail hereinafter and illustrated in the accompanying drawings in which- Figure 1 is a front viewof the gate, showing the boxing containing the gate and latch operating mechanism in section, Fig. 2, an

view of the gate with the boxing in section. Fig. 3, a top plan view of the operat ingmechanism, Fig. 1, a detail view of the latch lever operating mechanism, and Fig. 5, a detail of gate latch operating mechanismjlfig 6, a sectional view onthe line of Fig. 5, Fig. 7, a View of the latch postand latches, and Fig. 8, a detail View of one of the latch levers for holding the gate an open position.

In the drawings similar reference characters indicate corresponding parts in all of the views.

1 indicates the hinge post and 2 the latch post between which is swung the gate 3 secured to a vertical shaft- 4; journaled on post 1 and having its lower end resting in a socket 5 secured to the base 6 of a housing; or boxing 7 for the operating mechanism.

8 indicates a dish secured to shaft 4 and having an upstanding flange 9 thereon iormed with e-Qnotch 10,

11 indicates a lever fnlcrumed on shaft 4 and having one end mounted innotch while its other end has ropes, chains or other flexible elements 12 secured thereto that extend through branches 13 of housing 7 to to arms 1 1 of shafts 15 gonrnaled at a distance from the gate at either side thereof. Shafts 15 are formed with upwardly extending crank portions 16 that are positioned to he engaged the wheels of vehicles approaching or leaving the-gate 17 indicates springs secured to disk 8 and engaging opposite sides of le 11 to hold it normally midway between the sides of notch 10.

18 indicates latch rods slidably mounted on latch post 2 which have their upper ends bent and inclined downwardly as shown at 19 to receive a pin or projection 20 secured to and extending outwardly from the end of the gate. 18 are pivotally secured to levers 21 ful- The lower ends 'Of latch rods crumed on. bar 22 secured to cars 23, said le- I vers and their support being mounted in housing 94: under gate 3.

25 indicates carved wings pivotally secured to a support 26, the free ends of levers 21 being loosely secured to said wingsand 27 indicates triangular shaped plate secured to the end of lever 11 and positioned so that two of its sides engage the wings 25 when the lever 11 is moved by the crank shafts 15 as hereinbefore stated, it being understood that when the shaft 15 at one or the other side of the gate is rotated by an approaching vehicle, the first efiect is to swing the lever 11 so that the end of lever 21 secured to the latch rod 18 atthe farther side ofthe gate from the vehicle is raised by the triangular plate 27 engaging wings 25, then when the lever 11 engages the side of notch 10 the disk 8 and shaftis rotated carrying with it gate 3.

28 indicates counter balance weights mounted .on levers fllthat tend to hold the latch rods 18 in their raised position to en gage pin 20.

29 indicates levers journaled on the inner sides of top plates 30 or branch housings 13 that have upwardly extending portions .31 that extend through openings 82 in the top plates and formed with downwardly in- (lined ends 33 to engage the bottom of gate 3 when swung open, the other ends of the levers having; plates 34 thereon to engage. arms 14 of. shafts 15 .when rocked by the vehicle passing over the crank 16 of the shaft after passing through the gate. 35 indicates a counter balance weight-on each lever 29 to hold the upwardly extending end 31 in position to engage the gate when swung open,

36 indicates a weight connected to the.

disk 8 by means of a ropeor chain 37 mounted on sheave 38 and extending through tubular guide 39"that operates to closefthe gate whenthe end 31 of either lever'29 is released therefrom.

When the gate is opened, as heretofore described, by the approaching vehicle, passing overcrank 16 of shaft 15, it swings the gate 3 away from the approaching vehicle and-into engagement with the end 31 of lever 29, the inclined end 33 of the lever by engaging the gate causes the end 31'to be depressedqso that the gate passes itand it operates as a latch to prevent the'gate from closing. .After the vehicle passes through gate. The weight 36 will then close the,

the wheels are driven over the crank 16 of shaft' 15 on the side of the gate opening. to which the gate has-swung so that the arm 14: is swung into contact with the plate 34: on the end of the lever lifting it'and swinging the end 31 'out of engagement with the gate, the pin 2O on the end of the gate, by engaging the inclined ends 19 of the latch rodat the near side'of the latch post 2, depressing the rod until the gate closes, when i the counterbalance weight 28 on the lever will return the latch 'rod to its normal position' and the gate will beheld in a closed position.

Having thus described my invention what I claim is tively secured to the latch "40 shaft, a disk 1. Agate operating mechanism comprisshaft, the gate secured to the ing a vertical secured to the shaft, a lever mounted on the disk, latch rods suitably mounted to engage the gate, levers operarods, curved wings. pivotally mounted and loosely engag-' 7 ing the latch operating levers,

the first mentioned lever constructed to engage the wings aforesaid, and mechanism operated by the weight of a vehicle approaching the gate to swing thefirst mentioned lever.

"2. A gate operating mechanism comprising a vertical shaft, the gate secured to the, shaft, a disk secured to the shaft, an up standing flange around said disk and having a notch therein, a lever mounted on the disk seatedin thenotch, springs secured to the diska'nd engaging the levers to normally hold it" from engagement with the sides of the notch, "latch rods suitably mounied to engage the gate, levers operatively secured to the latch rods, "curved wings pivotally fioples of this patent-may be obtained for five cents each, by adfiressing' the tance eachside of the mounted and loosely engaging the latch operating levers, a triangular plate mounted on one end of the first mentioned lever and engaging the wings aforesaid, and means operated by the Weight of avehicle approaching the gate to swing the first mentioned lever.

mg a vertical shaft, thev gate secured to the.

shaft, a disk secured'to'the shaft, an upstanding'flange around said disk and having a notch therein, a lever mounted on the disk and seated in the notch, springs secured to the disk and engaging the lever to normally hold it from engagement with the sides of the notch, latch rods suitably mounted to engage the gate, levers operatively secured to the latch rods, curved wings pivotally mounted and loosely engaging the latch operating levers, a'triangular plate mounted on one end of the first mentioned lever and engaging the wings aforesaid, crank shafts 3. A gate operating mechanism comprisjournaled at a distance on each side of the gate and adapted to be actuated by a vehicle approachingthe gate, arms on said shafts,

and flexible members connecting the first mentioned lever and said arms.

4. In combination with a swinging gate,

a lever fulcrumed at a distance each side of the gate, one end of each lever extended upwardly to engage the gate when opened, the other end of each lever extended horizontally, crank shafts positioned to be engaged by a vehicle passing through the gate opening, and a swinging arm on each shaft and positioned to engage the horizontal portion of the adjacent lever and move its upwardly. extending end from engaging the gate.

. 5. A of a vertical shaft, the gate operatively connected to saidjlshaft, crank shafts at a disbe rocked by avehicle passing over them, a disk secured to said vertical shaft, an upwardly extending flange on said disk and having a notch therein, a-ievercon thedisk and mounted in said notch, and operative connections shafts.

In testimony whereof" I hereto afiix my gate and adapted to between said lever and the crank gate operating mechanism consisting signature in the presence of two witnesses.
