GATE.

SPECIFICATION foiming part of Letters Patent No. 558,188, dated April 14, 1896. Application filed May 9, 1895. Serial No. 548,748. (No model.)

To all whom it may concern;

Be it known that 1, PETER M. LINQUIST, a citizen of the United States, residing at Elsmore, in the county of Allen and State of Kansas, have invented a new and useful Gate, of which the following is a specification.

The invention relates to improvements in gates. i

The object of the present invention is to improve the construction of tilting gates and to provide a simple and inexpensi ve one which will not be affected by snow-drifts or the like and which may be readily opened and closed by the wheels of a vehicle or by hand.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective View of a gate constructed in accordance with this invention and shownclosed. Fig. 2 is a side elevation, partly in section, the gate being open. Fig. 3 is a horizontal sectional view of the rear portion of the gate, the latter being closed.

Like numerals of reference indicate corresponding parts in all thefigures of the drawings.

1 designates a tilting gate composed of top and bottom longitudinal bars 2 and 3 and vertical pickets 4, located at opposite sides of the longitudinal bars 2 and 3 and pivoted to the same. The upper longitudinal bar 2 is provided with a rearward extension and is pivoted by a horizontal pin 5 between sides 6 of a hinge-post 7, and the gate is adapted to tilt or swing upward on the pivot 5, as illustrated in Fig. 2 of the accompanying drawings. The lower longitudinal bar 3 of the gate is provided at its rear end with a projecting loop 8, which passes through an opening of a block 9 and receives a transverse pin 10, which limits the swing or longitudinal movement of the lower bar 3. The block 9 is interposed between the sides 6 of the post 7, and the lower bar abuts against it whenthe gate is closed, and when the gate is being opened the rear end of the lower bar 3 of the gate moves upward and outward from the block 9 the length of the link 8, after which the bar 3 has a steady rearward swing.

A weight 11 is mounted on the rearwardextending arm of the gate and is adapted to counterbalance the weight of the gate and to enable the same to be swung upward and downward with little labor, and also to cause a large and heavy gate to operate as easily as a smaller and lighter one. This weight may be of any desired construction, and the rearwardly-extending arm of the gate is formed by the extension of the upper bar 20f the gate and side pieces 12, secured to opposite sides of the bar 2.

The opening and closing of the gate is facilitated by a sliding weight 13, provided at its top with grooved rollers 14 and depending from an inclined track 15, extending upward and rearward from the front of the gate and consisting of a rod or the like. The grooved rollers 14 are journaled in a hanger 16, which is substantially U-shapedin cross-section, and between the sides of which the track is arranged.

As the gate is elevated sufficiently to incline the track in the opposite direction from its position when the gate is closed, the weight 13 slides from one end of the gate to the other, overbalancing the front portion of the gate and causing the same to swing upward under the impulse of a very slight pull on operatingropes 17. When the gate is closed by operating-ropes 18, the track bar or rod is returned to its normal inclination and the sliding weight 13 returns automatically to its initial position. The rear end of the track is supported by a suitable post 19, and has, mounted on it a cushion 20 to receive the blow of the weight 13 and to prevent the gate from being racked or otherwise injured by the sliding of the weight. An arched support or shield 22 is mounted on the rearward-extending arm of the gate and straddles the track and extends a sufficient distance above the same to permit the sliding weight to pass freely, under it.

The gate is further supported by a pair of links or plates 23', pivoted to the outer faces of the sides 6 of the posts 7 and to opposite sides of the counterbalancing-weight of the gate. These link-plates support the gate and prevent the pivot thereof from being twisted or wrenched by the opening and closing of the gate.

A pair of operating ropes orconneotions 17 and 18 extend from opposite sides of the gate to enable the latter to be opened and closed from a distance without leaving a vehicle. The inner ends of each pair of operating- ropes 17 and 18 are secured directly to the counterbalancing-weight and extend upward and downward therefrom in order to swing the rearward-extending arm of the gate upward or downward to effect an. opening or closing comparatively inexpensive in construction,

of the gate. The operating-rope 17 extends downward below the rearward-extending arm and passes around a pulley 24 at one side of the post 7, and then upward over a pulley 25 of a post 26 and over a sheave of a double pulley 27 of an upright 28; The other operatin g-rope 18 extends upward from the counterbalancing-weight and the rearwardly-extending arm of the gate and passes over a sheave of a double pulley 29 of an upright 30, located in rear of the gate. The operating-rope 18 then extends outward from the upright 30 and passes through a guide at the top of the post 26 and over the other sheave of the double-pulley block 27 of the upright 28. The guide of the post 26 maybe of any desired construction and is preferably provided with a pulley 31 to enable the operating-rope 18 to run smoothly through the guide.

The outer ends of the operating- ropes 17 and 18 of each pair are attached, respectively, to arms 32 and of rock- shafts 34 and 35. The rock'shafts are journaled in suitable hearings on the surface of the ground and extend transversely of the roadway and are provided at their outer ends with crank-bends 36 and 37, adapted to be engaged by the wheels of a vehicle. The arm and the crank-bend of one shaft are arranged at right angles to the arm and bend of the other shaft. and when one crank-bend is in a vertical position to be operated or depressed by the wheels of a vehicle the other is in a horizontal position and is elevated to a vertical position as the firstmentioned crank-bend is swung downward. The outer crank-bend 36,0r the one the greater distance from the upright 28, is adapted to be swung downward toward the gate to open the same. The opening of the gate raises the crank-bend 37 of each rock-shaft into a vertical position andv prepares it to be engaged by the wheels of a vehicle after the latter has passed through a gate for the purpose of clos ing the same.

Instead of operating the gate by the wheels of a vehicle it may be operated by the weight of a person stepping on the crank-bends, and, if desired, handles may be provided for the outer portions of the operating-ropes depending from the arm of the upright 28.

It will be seen that the gate is simple and ward and provided with a rearward extension, a weight mounted on the rearward extension and adapted to counterbalance the gate, links located at opposite sides of the post and pivoted to the same, and to the counterbalancing weight, and a sliding weight mounted on the gate, substantially as described.

2. The combination of a post, a gate pivoted to the same and arranged to swing upward, and provided with a rearward extension forming an arm, a counterbalancingweight mounted on the arm, a track bar or rod carried by the gate and arranged at an inclination, a sliding weight depending from the track bar or rod and provided with rollers to travel on the same, a cushion located at the rear end of the same and arranged to be engaged by the sliding weight, and operating-ropes extending upward and downward from the arm of the gate and adapted to swing the same in either direction, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.

PETER M. LINQUIST.
