SPECIFICATION forming part of Letters Patent No. 439,460, dated October 28, 1890.

Application filed March 13, 1890.

To aZZ whom it i12/ay concern:

Be it known that I, THOMAS J. AUSTIN, of .Belle Plain, in the county of Callahan and State of Texas, have invented certain new and useful Improvements in Gates; and I do hereby declare that the following is a: full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to gates, and has for its object to provide an improved gate which is strong, durable, economical of manufac ture, and reliable in operation 5 and to these ends the said invention consists in the novel construction and new combinations of parts, 'as hereinafter described and claimed, refer ence being had to the accompanying drawings, in which- Figure l is a perspective View showing my improved gate in its closed position. Fig. 2 is a front View of the same in its open position, omitting for the sake of clearness the outlying standards. Fig. 3 is a detail vertical central section. Fig. it is a view showing a portion oi' the endless chain, and Fig. 5 is a detail view of the latch.

In the said drawings, the reference-letters B designate vertical posts or standards, to the upper ends of which is bolted or otherwise sustably secured the horizontal beam or bar C.

The letters O indicate top rails or bars, depending frorn which are the gate-sections D, and extending upwardly from which are brackets H, in which are journaled frictionrollers I, said rollers traveling on any suitable track (not shown) on the upper surface of the beam or rail O.

Secured at one end to the verticalstandards 4o and at the other to the cross beam or bar C are yokes or stirrups G, each of which is provided with an axis S, upon which is j ournaled a pair of pulleys E. y

Vithin each yoke or stirru p G and arranged between the pulleys E is a spur-wheel E, upon which travels the endless chain J. These pulleys E and spur-wheels E are either made integral or are securely fastened together in order that they may move in unison, as may 5o be found preferable. The chain J is contion.

Serial No. 343,813. (No model.)

nected with the two inner brackets H by a link, as shown, or other suitable means, one

of said brackets being extended in order that it may be connected to that part of the endless chain which is uppermost asit lies upon the spur-wheels F.

To the standards B are secu red brackets T, cach of which is provided with a series of three horizontal arms, between which are arranged two pulleys T one above the other.

Arranged at a suitable distance froln the gate, at each side thereof, are four posts or standards lettered K, to the upper ends of which are secured brackets L, within which are arranged pulleys L.

Secured at one end to each of the four pulleys E is a cord, chain, or wire n, which cords are wound around said pulleys several times, (according to the distance traveled by the gatesections in opening and closing) then 7o passed around their respective pulleys T', and thence over their respective pulleys L. The two cords for operating each gate-section are wound in reverse directions upon the corresponding pulleys E, so that a pull upon one of the cords will cause the gate to open, while a pull upon the other will close the same. To the ends of said cords, chains, or wires, opposite the ends secured to the pulleys E, are secured counter-weights N', the object of which 8c is to retain the cords, chains, or wires in a taut condition and to alford a convenient hand-hold.

The letters B. indicate any suitable guides for the bottom edges of the gate-sections.

To one of the gate-sections is secured a latch P, consisting of a vertical arm, preferably extending through an orifice in the top rail or bar C and engaging with the endless chain J, and a lateral extension having a lug to en- 9o gage a suitable device on the other gate-sec- The said latch is thrown into locking engagement, and there normally held by a suitable spring O, as shown.

In Fig. et I have shown the preferred form of chain L, in which the links are in form somewhat acute-angled, and each link is open at one end and its ends are turned into engagement with the next following link.

The operation on my improved gate is as roo follows: To open the gate, the operator pulls the cord n, (at the right-hand side of the gate, for example) which causes the pulleys E, to which it is attached, and at the same time the spur-wheels F to revolve, the latter operating the endless chain, whose initial movement throws the vertical arm of the catch P and releases the gate-sections, whereby said gate-sections are caused to move in opposite directions by reason of their connection-one with the uppermost and the other with the lowermost portion of the endless chain-as it lies on the spur-wheels F, as hereinbefore describedE After the operator has passed through the gate he operates the corresponding cord n, and the gate is closed through the same instrumentalities by reason of this 'cord being wound on the pulley E in a direction the reverse of that which was operated to open the gate. It will be observed that should either of the ropes for operating the gate-sections become broken the construction is such Ythat the connection between the gates will remain unimpaired, and until the broken rope is replaced the gates can be operated in that direction by hand.

Gates of this class have heretofore been operated by an endless rope running over a series of pulleys, said rope having an attached handle, which is moved toward and from the gate to operate the same. In this construction if the handle nears the pulleys the power becomes weakened, and the handle is also liable when the rope becomes slack by reason of rain to work under the pulleys, thus obstructing its free operation. Again, in such gates it is necessary to have out-posts at a considerable distance from the gate, according to the distance the gate -sections are to move in opening and closing, and the operator is obliged when opening the gate to move a considerable distance. All these obj ections are avoided by myinvention, which provides a gate which is durable, economical, and ei'- fective in operation.

Vhat I claim is- 1. In a gate, the combination of a top beam or bar supported upon vertical standards,

' gate-sections hung thereupon, the pulleys E,

the spur-wheels F, the endless chain thereon connected with the gate-sections, the horizontal pulleys T', and the cords n, wound in reverse directions upon said pulleys E, substantially as described.

2. In a gate, the combination of verticall standards, a top beam or bar supported thereby, gate-sections, brackets H, secured to the top rails of said gate-sections, friction-rollers j ournaled in said brackets and moving on the said top beam or bar, brackets secured to said vertical standards, pulleys and spurwheels E and F, journaled therein, an endless chain upon said spur-wheels connected to the two inner of said brackets H, horizontallyarranged pulleys T, journaled in brackets secured to said vertical standards, the posts K, having pulleys L', and the cords n, passing over said pulleys L and T and wound in reversed directions upon the pulleys E and secured thereto, substantially as described.
