- IMPRovEMENT IN GATES.

The Schedule referred to ln thee'ietters Patent and making pari. ol' the name.

I, URIAH W. HARDY, of Abingdon, 'in the countyof Knox and State of Illinois, have invented .certain Improvements in Gates, of which the following is a specilication- Nature and Objects of the Invention.

The nature of my invention relates to improvements in that class of gates known as folding-bar gates, 'in which the bars fold up and assume a vertical position when the gate is opened l; and the invention Aconsists in the combination bf a stay with the pivotposts and operating-levers, so constructed as to allow of the free working of' the levers, as required, and at 'the same time keep the levers in place, all as hereinembodying my invention, and representing the gatel clgsed.

Figure 2 lis a perspective view of a gate complete, embodying my invention and representing the gate open.

General Description. Letters A represent the horizontal gate-bars.

Letters B represent the cross-bars.

C is the latch-post, with ledges c c c c, at its upper and lower ends; to form guides for .the end of the gate while -opening and closing, and stays, when the gate is shut.

D D are the pivot-posts or side-posts,

E E are the operating-levers." i vl? E are posts, on which the levers E E are pivoted. l

G is a stay, attached to and projecting upward from the side of one the posts D, and its upper part inclined, as shown in the drawing. i

H is the latch, pivoted on the upper side of the upper horizontal bar, by hinges I I, either on top of the said bar with a stop-pin at its rear end, or in a suitable place cut in the bar, as shown-in the drawing, so that when 'the latch is drawn back its rear end will 'strike the shoulder a; i

`The lhinges I I are attached, as shown plainly, so

that, when the latch His drawn back, the hinges still incline forward, kin order that when the latch is released 'and in a horizontal position it will drop downwardand forward by the force of its own gravity, and engage with any suitable recess iu the post O.

The adjacentends of the levers. EE areconnected by a ring, e, and staples c'c'.

J is a chain, extending from the :ring c to the staple h, ou the rear end ot' the latch H.

K is a chain, connecting the adjacent ends 'of' the levers E E with the top bar A, at a point alittle ,forward of the point at which the bar A is pivoted in the posts D D.

- to the edge ofthe posts D D, as 4shown by the dotted lines at g. 1,"to assist in holding the gate aslast de- L is a weight on the bar A, which is extended for its attachment in the usual manner in this class of gates, land. is so poised that the weight and gate balance each the other when the gate stands at an angle of about vseventy degrees; passing which in closing p the gate will close itself, and passing which in opening it will open itself. p

The posts C D D F F, may beset in the ground, or they may be set in a frame, M. v

The construction and operation are as follows:

The bars A are pivoted on a slope line, between the posts D D, at the points a wa a a a af a so that they may stand side by side when the gate is open, and their. lower ends rest between the posts/D D, holding the` gate iirmlyagainst wind, or vibration sidewise, from any cause, while open and while being opened.` v

Iheends ofthe upper bars A A A A AA, are eX- tended back past their pivoted -points a.' a a a a a',

scribed.

Iuopening the gate, the personv approaching it takes. hold'of the free end of one of the levers E, which are pivoted loosely ou top of the posts F, and, drawing it slightly horizontally, releases or draws back the latch H by the chain J then by drawing the same end of the lever E vdownward the chain K will raise the gate to the angle of seventy degrees, passing which it will, with `the aid of the momentum acquired, carry itself to a vertical position.

In closing the gate the outer end of either lever E isthrown back horizontally, and its other end striking the upper gate-bar A, will carry it past the inclination of seventy degrees from the horizontal, from which point it will close itself.

'llo enable the levers E to have side motion suiicieutly in closing the gate, the upper end of the-,stay

.G is inclined, as showu plainly at figs..1 and 2, and

when the gate is open the ends ofthe levers E E, adjacent to.each other, are brought up opposite said incline. When the gate is closed the saine ends of the levers drop to the vertical part of the stayI G, which holds them in position for convenience in reaching by the approaching horsemau or other person.

. Claim.

yI claim as my invention- The stay G, when constructed as described, with an inclined top, and combined with the posts D, levers E E, and bar A, substantially as described, and for the purpose specified.
