GATE.

SPECIFICATION forming part of Letters liatentl No. 589,134, dated August 31, 1897?` Application filed May 24, 1897. Serial No. 637,842.. (No model.)

To @ZZ whom it may concern: Y

Be it known that I, JACOB B. MIESSE, a citizen o f the United States, residing at Nobles-A Y Ville, in the county of Hamilton and State of Indiana, have in vented'a new and useful Gate, of which the following is a specification.

My invention relates to an improvement in automatic sliding gates.

The object'of my invention is to provide mechanism by means of which a sliding gate, may be automatically opened or closed by the passage ofa vehicle along the roadway leading through such gate.

The accompanying drawings illustrate my invention.

Figure 1 is a side elevation showing the gate closed. Fig. 2 is a side Velevation showing/the gate open. Fig. 3 is a plan of Fig. l. Fig. 4 is a sectional detailof the pivoted guide and the sliding weight mounted therein.

In the drawings, 6 indicates the gate-posts, to the'upper ends of which is secured a transverse track 7. Posts 6 consist, preferably, of two sections, between which the gate may move, but single posts may be'used,if desired. Mounted beneath track 7 and suspended therefrom by means of rollers 8 are two gatesections 9 andlO, the arrangement being such that the said gate-sections may be mpved along said track ac ross the roadway. Mounted to one side of the road, near one of the posts 6, is a post 11.` Pivoted upon post 11, so as Ito swing in a plane substantially parallel with the plane of the gate, is a guide l2, within which is mounted a sliding weight 13, provided with suitable .rollers 13". Extending upward from weight 12 is a shank 14, through which an opening 15 is formed substantially at right angles to the path of movement of l oted to the gate-section 9.

the weight. Mounted in opening l5 and secured therein by means of a set-screw 16 is an arm 17, the outer end of which lies within a slot 18, formed in the outer or free end of an arm 19, 'the opposite end of which is piv- Pivoted near post 11, so as to swing in a substantially horizontal plane, is a lever 20, to each end of which is secured a cord 2l. Each of cords 2l is passed beneath a pulley'22, which is carried by a yoke 22", pivoted so as to swing in a substantially horizontal plane, and the ends of said cords are secured to guide 12, one to each side of the pivot thereof.

Mounted at each side of the gate, at some distance along the roadway therefrom, is an operating-lever 23 of the usual well-known form,`the said lever being provided with a pair of

arms

24 and 25, which are adapted to be engaged by the wheels of vehicles. Secured to lever 23 is a link 26, the opposite end of which is pivoted to one arm of lever 20, the throw of said lever being regulated by placing the end of said link within any one of a series of holes 27, placed at different distances lfrom the center of the lever. In order to cause the two gate-sections to move simultaneously in opposite directions, I secure to the upper end of section 9 a rack-bar 23, and to section 10 is secured a similar rack-bar 29, the said rackbars lying parallel with each other andthe teeth thereof engaging opposite sides of a small pinion 30. By this means any movement of section 9 causes, through the rackbars and pinion, a corresponding opposite movement of section lO. The rack-bars23 and 29are hield in engagement with pinion 30 by means of small idlers 3l. In order to protect the interior of guide 12 from rain, snow, dsc., I mount over the upper part thereof a hood 32, beneath which shank 14 of the sliding'weight moves, a slot 33 being formed .through one side of said 'hood to permit the passageof arm 17. The hood 32 is shown in detail in Fig. 4, but has been omitted from the other figures for the sakel ofclearness. It is advisable to protectutra'ck7 and the parts operating thereon, and for this p urpose I-fprovide a 'oof 34. (Indicated in dotted lines in Fig. 1.

The operation is as follows: Supposing the gate to be closed, the-various parts will be in the position shown in Fig. y1. The wheels of one side of a vehicle passing along the roadway toward the gate will comein contact with arm 24 of one of levers 23 and force the said lever forward and downward. This movement of lever 23 causes-a swinging movement of lever 20, which, through cords 21, causes guide 12 to swing upon its pivot, thus raising weight 13 above the pivot of .the guide. Weight 13 then slides downward along guide 12, carrying with it arm 19 and gate-section IOO 9, to whieh itis pivoted. The outward movement of section 9 Causes, through rack-bar 2S, pinion 30, and1aek-bar29,a Corresponding outward movement of gate-section 10. The vehicle then passes through and comes into engagement with arm 25 of the other lever This causes guide 12 to return to its original position, when weight 13 again slides downward along the guide and returns the various parts to the original position.

It will be noticed that in either position of the gate weight 13 holds arm 17 in engagement with one end or the other of slot 1S of arm 1), so that the said weight operates to prevent the accidental opening or closing of the gate.

I claim as my invention- 1. The combination with a gate, of a pivoted guide, a weight mounted so as to slide along said guide, an arm pivoted to the gate, an arm carried by the weight and adapted to engage said rst-mentioned arm, and means for swinging the guide.

2. The combination with a gate, of a pivoted guide, a weight mounted so as to slide along said guide, intermediate connecting mechanism between said weight and gate whereby a down ward movement of the weight along the guide will cause a movement of the gate, an operating-lever 23 mounted in the roadway, and intermediate oonneeting meehanism between said lever and the pivoted guide whereby the operation of said lever will eause a swinging movement of the guide.

3. The combination with a gate, of a pivoted guide, a weight mounted so as to move along said guide, an arm Carried by said weight, an arm pivoted to the gate and adapted to engage said iirst-mentioned arm, an operatinglever 23 mounted in the roadway,

lever 20, eords 21 connecting the ends of said lever with opposite ends of the pivoted guide, and a

link connecting levers

23 and 20, all combined and arranged to cooperate substantially as and for the .purpose set forth.

l. The combination with a pair of sliding gate-sections, of a pivoted guide, a weight mounted so as to slide thereon, intermediate connecting mechanism between said weight and one of the gate-sections, means for swinging the pivoted guide, and intermediate eonneeting mechanism between the two gate-seetions whereby a movement of one of said sections will eause a similar opposite movement of the other seetion.

rlhe Combination with a pair of sliding gate-sections, of a pivoted guide, a weight mounted so as to move along said guide, intermediate connecting mechanism between said weight and one of the gate-sections, means for swinging the pivoted guide, a raekbar Carried by each oi the gate-sections, and a pinion engaging both oi' said rack-bars, all combined and arranged to cooperate substantially as and for the purpose set forth.

6. The Combination with a pair of sliding gate-sections, of a pivoted guide, a weight mounted so as to slide thereon and provided with suitable rollers7 an arm earried by one of the gate-sections and adapted to engage the weight, a rack-bar carried by eaeh gatesection, a pinion engaging both rack-bars, lever Q3 mounted in the roadway, lever 20, eords 2l, and link 2G, all combined and arranged to cooperate substantially as and for the purpose set forth.
