GATE-OPENER.

To all whom ttmcy concern:

Be t known that I, FRANK A. Scnusrnn, a resident -01 Pittsburg, South Side, in the county of Allegheny, and State of Pennsylvania, have invented a new and useful Irnprovernent'in Gate Openers and I do hereby declare the iollowingto be a full, clear, and exact description thereoi.

My invention relates to devices for opening and closingswingingigates, and has special reference to such devices operated by the vehicle inpassing over the same;

The object of my, invention is; to provide a cheap, simple and 'eflicient apparatus for opening and closing swinging gates through the wheels of a vehicle engaging with such devices in such ainanner that the gateswill be insured "of opening and closing when demy invention appertains to construct and use my improved apparatuslor opening and closing swin ing gates, I will describe the same more hill referring to the accompanying drawing in which Figurell is atop plan view of a pair of swinging gates showing my invention applied thereto.

spiral spring'5 around the same and. connected thereto at one of its ends, while the other ends of said springs are adapted to bear against said posts.

Connected to the lower end of each of the bars 4 is an arm 6 which extends under said gates from their inner sides a to the outer sides I) of the drive-way A and said gates, and

a rope orchai-n 7 is connected at one end to each of said arms and passesaround a pulley 8 in a bearing 9 on the inner side of the driveway A andon each side of the same. A rope or chain 7 is connected at one end to the rope or chain 7 and passes around a pulley 8 in said bearing, and the rope or chain 7 passes from its pulley 8 into a pipe 10 extending under the gates 1 from the one side of said bearing to the outer sideof said gates andsecured in bearings 1 1' on each side of the driveway A, while the other ro as or chain 7 passes from its-pulley 8 into a like pipe 10' extending from the other side of the said bearing on theinner side of said gates and secured in like bearings 11 on each side of said driveway. The ropes or chains 7 and 7 are each connected at their other ends to one end of a spiral spring 12 in each of the pipes 10, and the opposite end of said spring is connected to one end of a rod- 12 which passes throughthe outer ends of said pipes and is connected at its other end to one end of alever 13 of the operating devices 14. These operating devicesll are four in number, twobeing located on each side of the gates 1- and each of such set of two being located on each side of the drive-way A.

The levers 1'3 of the operating devices 14. are each adapted to fit loosely at their ends around a in 1. 4e rigidly mounted in abearing block 15 in said devices and passing through a boss 16-above said endsa-nd through a gear segment 17 'at the upper end of said boss. An operating bar 18 extends through and is journaled in each of the blocks 15 and in the bearing 1 9 at the inner endsof the same,. and such ends are provided with a crank portion 20 within the same. A gear segment 21 is loosely mounted on each of the bars 18 for engagement with thegear segment 1-7 on the levers 1'3 and the hub 22 on the segment 21 is provided with a raised portion or lug 23 to engage with the crank 20 on said bars in operating' said segments 17 and 21. The outer ends of the bars 18 are loosely connectedto one end of the rods 24 which are mounted in bearings 25' and are provided with a crank arm 26 at their inner ends connected to said bars and engaging with a pin 18 thereon. An arm 24 is formed on the outer ends of the rods 24 and a rod 27 is adapted to be connected to said arms on the inner side of the gates 1 and the inner ends of the two spring latches 28 and one end of the levers 33 on the outer side of the said gates. These latches 28 are each located on the inner side of the drive-way A and on each side of the same and are pivotally mounted at 29 in a bearing 30 on a post 31, while the outer ends of said latches are connected by the rods 32 with the arms 24 on the outer side of the said driveway and with one end of the levers 33 on the inner side of said driveway. The levers 33 g are pivotally mounted on a pin 34 in a bearing 35 and are provided with a stop portion 36 at the other ends of the same. A spiral spring 34 is connected around the pin 34 and is secured at its ends to the bearing 35 and the portion 36 on the levers 33.

Extending out from the upper ends of the bars 4 is an arm 37 which is connected to the handle end 38 of a bell crank lever 38 pivoted on the gates 1 through a jointed rod 39, and a vertical rod 40 connects the other end 38 of said lever with a lug 41 on a spring latch 41 secured to the under face of said gates. Each of the latches 41 on the gates 1 are adapted to engage with a central block 42 located in the drive-way A, and such block is provided with sloping or inclined sides 42' and with a slot 43 within the same for the reception of said latches when the said gates are in their closed positions to lock the same.

8 A lug 44 is formed on the gates l for the arms 37 to engage with in the closing of said gates.

The use and operation of my improved apparatus for opening and closing swinging gates is as follows-With the parts in position as shown in Fig. 1, and the gates 1 closed, the wheels of a vehicle to operate said gates will strike the crank 20 in moving toward said gates on either side of the same, and depress or rock said cranks toward said gates, as shown by the dotted lines of the inner drive-way side a Fig. 2, so that the vertical portion of said cranks will engage with the lugs 23 on the hub of the gear segments 21, to rotate said segments and in turn the se ments 17 carrying the levers 13, which wil move said levers in a direction away from said gates. These levers 13 in their rearward movements will operate through the rods 12, springs 12 and chains 7 to rotate the spring hlnge bars 4 upon the gates 1 through the arms 6 on said bars, and as the bars 4 are thus rotated the ate latches 41 are first operated by being re eased through the lugs 44 at the tops of said bars drawing upon the jointed rods 39, which in turn operate the bell cranks 38 to lift the said latches from their seats 43 in the blocks 42 and through the connecting rods 40 to open the gates 1. While the latches 41 are thus being released in the manner just described, the

springs 12 connecting the chains 7 with the tion shown in Fig. 1*, while at such time the said gates are held open by the spring latches 28. When the levers 13 reach their most rearward position they engage with the spring actuated stop levers 33 and passing same they are held in their rearward positions by the stop portions 36 on said levers 33. After the gates 1 are thus opened they are held on the inner side a of the drive-way A and at the sides of the same by means of the latches 28 engaging with the sides of the same until the vehicle in passing through the gates and upon the wheels of the vehicle coming in contact with the crank arms 20 on the outer side I) of the said drive-way they will depress said arms in a direction away from the gates 1. In this movement of the cranks 20 the gearing 1.7 and 21 on the outer side I) of the drive-way A will not be operated by reason of said cranks moving away from the lugs 23 on gear segments 21, but operated only to rock the shafts 18 of said cranks and rods 24 through the pins 18 on said shafts engaging with the arms 26 on said rods, which rocking movement operates through the rods 32 to operate the latches 28 and release the gates 1 which are held closed by the springs 5 on the bars 4 through the arms 37 contacting with the lugs 44 on said gates. The rods 32 being continued past the latches 28 and attached to the ends of stop levers 33 will act to release the arms 13 from the levers 33 simultaneously with the releasing of the gates 1 and thus allow all the previously operated parts to assume their normal positions. As the gates 1 close the latches 41 ride up the inchned side 42 on block 42 and become seated in the recess 43 in the said block to hold said gates closed until again operated either by a vehicle as above described or by hand, and when said gates 1 L are to be opened from the outer side I) of the drive-way a, the operation is the same, except that said gates open away from instead of toward the vehicle by reason of the chains 7 being first passed around the pulleys 8 and returning and being attached to gate operating arms 6.

It will thus be seen that my improved devices for operating swinging gates will enable them to be handled automatically by the wheels of the vehicle passing over the drive way and from either side of said drive-way, as well as such devices will enable the gates to be operated by hand, and all the arts being exposed and above the ground wilFperfected by thefweathenor elements, either in their operation or wear.

The devices can be applied to a single gate, and various other modifications and changes in the design, construction and operation of thevariousnparts of my improved devices for operating swinging gates may be resorted to, without departing from the spirit of the invention or'sacrificing any of its advantages. What I claim as my invention, and desire to secureby Letters Patent, is
