SE'ECIFGATION forming part of Letters Patent No. 666,376, dated January 22, 1901,

Application filed May 21. 1900.

T0 all whom it may concern:

Be it known that I, JOHN WILLIAM CARSON, a citizen of the United States, residing at Sangerville, in the county of Augusta and State of Virginia, have invented a new and useful Gate, of which the following is a specification.

My invention relates to improvements in gates, but more particularly to that type of gate which is adapted to be opened by a person approaching the gate Without necessitating his alighting from a conveyance and which is closed in a similar manner after the gate has been passed.

The object in View is to provide simple and durable gate-operating mechanism which will not only facilitate the swinging of the gate, but which will automatically effect the unlatching of the gate and the subsequent swinging of the gate upon its hinges without necessity for other manipulation of the device than the single movement of the gateoperating element, which in its broadest aspect may be defined as means for unlatching and operating the gate. Subordinate to this general object are several others, which will more fully appear in the succeeding description, which is directed to that structure illustrated in the accompanying drawings and embraced within the scope of the appended claims.

In said drawings, Figure 1 is a perspective View of my gate complete, illustrating it in its closed position. Fig. 2 is a side elevation, on a somewhat-enlarged scale, of the hinged end of the gate and the gate supporting and operating mechanism, the gate being in the closed position; and Fig. 3 is a similar View of thegate in one of its open positions.

Referring to the numerals of reference employed to designate corresponding parts in the several views, 1 and 2 indicate a pair of gate-posts, between which in its closed position is disposed the gate 3. The post l constitutes the support for the gate, which is hinged thereto by hinges 4 and 5, composed, respectively, of lapping hinge-plates extending from the rear of the gate and from the post l and having vertically-alined pintles. Various other forms of hinging means may be substituted, however, if desired. The

gate is preferably made up of front and rear i Serial No. 17,446. (No model.)

standards 6 and 7 and horizontal bars or slats 8, braced by a pair of parallel diagonal bracebars 9 and by short supplemental braces 10.

Around the rear face of the gate-standard 7 is bent and suitably' secured an angular plate 11, from which extends rearwardly a horizontal lug l2, provided with an oblong slot-'13, which in the closed position of the gate is located over a similar slot or opening 14 in a fixed lug or bracket 15, extending forwardly from the gate-post 1. rlhese openings 13 and 14 in the oppositely-extending lugs 12 and 15 are designed for the reception of an element which for the purpose of succinct definition in the claims will be variously termed an actuator,7 an actuating and latch-controlling element, and a spiral plate. This plate 16 is formed from a Hat strip of metal the cross-sectional contour of which corresponds to the openings 13 and 14. The lower portion of the plate l-that is to say, that portion which engages the fixed lug l-is twisted to form a terminal spiral 17, while its upper portion, which is designed to move Within the opening 13 of the lug l2, is fiat and untwisted and terminates above the lug 12 in a reduced neck 18, extending through a hori- Zontal eyelet 19, formed at the lower end of a pitman 20, preferably having its lower portion bifurcated or looped, as indicated at 21, and having a hook 22 at its upper end for engagement with an eyebolt 23, piercing a comparatively long gate-operating lever 24. The lever 24 extends at right angles to the gate when the latter is in its closed position and is fulcrumed upon a bolt 25, passing through a lateral projection 26, ext-ending from the post 1, in order to locate the fulcrum of the operating-lever a sufficient distance to one side of the pitman connection to insure the longitudinal movement of the plate or actuator 16 when the gate-operating lever is swung in a manner which will be hereinafter more fully apparent.

The extremities of the gate-operating lever 24 are located at the side of the road and at suicient distances from the post 1 to permit a traveler approaching or passing the gate to swing the lever for the purpose of effecting the swinging of the gate without danger of the operation of the latter being interfered IOO with by the operator. To facilitate the swinging of the lever, handle-rods 27 may be loosely connected to the outer ends thereof.

By reference to Fig. 1 of the drawingsjit will be noted that in the closed position of the gate those portions of the plate 16 engaging the openings 13 and 14 will be disposed in properalinement to permit alined positions of the openings. If now the operating-lever2-t is swung to depress the plate 16, the spiral 17, by reason of its engagement with a fixed part, will cause the plate to rotate, and as the lug 12, fixed to the rear standard of the gate, is irrevolubly engaged to the plain portion of the plate the rotation of the latter will cause the gate to be swung upon its hinges to an extentcontrolled by the extent of rotary movement of the plate. Thus the swinging of the operating-lever 24 either upon approaching the gate or after it is passed will effect the swinging of the gate from its closed position, as shown in Fig. 1, to its open position, as shown in Fig. 3, or from its open position back to its closed position, the direction of movement of the gate being governed by the direction of movement of the plate 16.

The device thus far described constitutes a complete embodiment of my invention in its broadest aspect, inasmuch as we have seen that by the cooperation of the elements enumerated the gate may be easily operated by the passing traveler without necessitating his alighting from the vehicle. I prefer to pursue the development of the device still further, however, and to provide for the latching of the gate in its Various positions and for the automatic unlatching of the gate by the initial movement of the mechanism which subsequently operates the gate. l therefore provide the gate-post 2 wi-th a keeper 2S, having a center recess 29 in its upper edge and cam-faces 30 at opposite sides of the recess. At a suitable point upon the diagonal braces 9 I pivot, as indicated at 31, a comparatively long latch-lever 32,'the front end of which is designed to engage the keeper 28 in the ordinary manner as the gate is swung into alinement with the posts 1 and 2 from either side, and this front end of the latch-lever is normally depressed by a spring 33, which serves to urge the latch-lever into engagement with the keeper, but yields sufficiently to permit the former to ride upon the cam-faces 30 as the gate is swung to the closed position. The rear extremity of the latch-lever 32 is straddled by the forward bifurcated extremity 34 of a bell-cran k lever 35, fulcrumed atits angle in the elongated bifurcated end 36 of a bolt 37, which passes through the standard 7 and plate 11 and is secured by a nut, as usual. The horizontal arm of the bell-crank leveren- -gaging the latch-lever is much longer than the vertical arm 38, which is pivotally connected to the rear extremity of what may be termed the latch-bar 39, passed through the standard 7 and plate 11 and having a beveled end 4:0, which is designed to engage one of a series of V-shaped notches or recesses t1 in one edge of the plate 16. The shape ofthe cooperating portions of the latch-bar 39 and the latch-operating member 16 is immaterial, however, provided there is such relation of the contacting faces of said members as will insure the longitudinal movement of the latch-rod 39 when `the plate or actuator 16 is moved longitudinally.

Now by again referring to Fig. 1 of the drawings it will be seen that in the closed position of the gate the latch-bar 39 will be in engagement with one of the notches -tl and that the front end of the latch-lever 32 will be in engagement with the recesses 29 of the keeper 28. If now the actuator or plate 16 is depressed by the swinging of the operating-lever 24, the first effect of such movement will be to force the latch-bar 39 out of the recess in the plate 16, which will cause the bellcrank lever 35 to be swung, the adjacent end of the latch-lever to be depressed, and the forward end of the latch-lever to be elevated out of the recess 29 against the resistance opposed by the spring 33. Continued movement of the plate 16 in the same direction will compel its rotation by reason ot the progress of the spiral 17 through the opening 14 in the stationary lug 15, and this rotary movement will of necessity be accompanied by the swinging of the gate because of the engagement of the dat upper end of the plate 16 with the opening 13 in the lug 12, iixed to the gate. The spiral 17 is so proportioned that when suflicient longitudinal movement has been imparted to the plate 16 to present the gate ina position at right angles to its normal position-as, for instance, as shown in Fig. 3- the latch-bar 39 will be opposed to another notch 41 in the edge ofthe plate 16 and will be urged therein under the impulse of the spring 33. Ordinarily this will take place just as the end of the latch-bar arrives above the recess 29 in a keeper mounted upon supplemental gate-posts located to retain the gate in its open positions, one of these posts being indicated by dotted lines in Fig. l of the drawings. Attention is called to the fact, however, that the latch-bar 39 constitutes of itself a positive latch for the gate, inasmuch as it retains the plate 16 against that longitudinal movement which is necessaryto the swinging of the gate, and the latch -lever and its cooperating parts may therefore be omitted in some constructions, and the application of spring-power to urge the latch-bar in the direction ot' the plate may be effected more directly. The location of the latch-bar at the hinged end of the gate, however, makes it desirable in many instances to employ a supplemental latch, located at the free end of the gate, and the construct-ion illustrated and described in detail is therefore believed to be preferable.

From the foregoing it will be observed that I have produced a simple and ingenious gate equipped with latching mechanism and with IOO gate-operating mechanism which are operated in succession for the purpose of unlatching and swinging of the gate by a single movement of the gate-operating lever; out while the present embodiment of my invention appears at this time to be preferable l wish to reserve the right to effect such changes and modifications of the structural details defined as may be suggested by experience and experiment and maybe embraced within the scope of the appended claims.
