IMPROVEMENT vIN APPROACH-GATE.

The Schedule referred to in these Letters Patent and making pari: of the same.

To all whom tit may concern:

, this specification- Figure 1 being an isometrical perspective of the gate as closed; y

Figure 2, a plan of the gate open. AFigure 3 is a 'view of the triangular eye enlarged. i Like letters of reference designate corresponding part-s `in'all the figures. v

-This invention has for its object a simple, cheap, and durable gate, one perfect in its action, and not liable fo get out oit order. I t belongs to that class known-as approach-gates, which are opened by equestri-ans, or those riding in vehicles, without dismounting, and possesses features of novelty and utility over all others now knowpy Y One important feature in my invent-ion consists in allowing the upper piutle of the hanging stile of the gate to turn in a triangular eye in a plate attached to the main or back gatepost, which allows the front stile of the gate to be raised, so as to release the lat-ch from its catch when opening the'gate, and also serves to release it from the bevelen stops when the gate is to he closed.

Another important feature of my invention consists in the use of elbow-levers pivoted to the oblique faces of the back gatepost,'which visset obliquely to` the roadway. The short suspended arms of these levers gate by means ofv chains, and the long horizontal arms project obliquely from their fulcrums to the axis of the roadway, or nearly so, so as to enable the rider to reach the short chains suspended from their cnds,'aud open the gate without dismounting.

A represents the gate.

13, the front gate-post.l

O, the main or back gate-post.- v l The hanging -stile D ot' the gate is pivoted at the bottom in the usual manner, and is provided with a pintle at the upper end, which turns iu an eye, c, iu a plate, t', secured to the post C. Tliis eye is in the form ot' au equilateral triangle, with the corners rounded, so as not to bind ou the pintle.

.E E represent the long arms oi' the levers, to the extremities of which the hand-chains b b arcattached. `To the rear ends are framed the levers S S, mak- 4 ving the proper angle therewith, as shown.

To the lower ends of these latter are attached chains ot' suitable length, at e e, the other ends ofthe said' chains being secured to the upper bar of the gate,

as'at d el.

In 4the frout'part of the gate is pivoted lthe latch 9 which wipes into the catch h, secured to post B.

G G are beveled stops, for holding the gate open, and

a a are the pivots on which the le vers E E are fulcrumed. Y

The Operation of the lifechanism. .The rider, on a load of hay, for instance, drives un -der the end of the lever, and, taking hold of the end ot' the chain suspended therefrom, pulls down. This action, through the medium of the chain connected with the lever on the otherside of the gate, and to the top rail of the gate, lifts the forward stile, thus releasing the latch ,from the catch, and, at the same time, pulls the gate open until the bottom ruil catches behind the beveled stop, which holds it open. After passing through, a similar pull ou theothcr lever. llisengages the gate from the stop in the same manner that the latch was released, and draws it shut, the latch wiping into its catch, as will be seen.

The action rcquiredin opening and closing, the gate is positive, and does not, in any degree, depend on gravity.

The triauguiar-shaped` eye in which the pintle turns I consider novel, and its action peculiar. When the gate is closed, the piutle rests in the forward corner of the triangle, (see tig. 3;) but when the chain which connects the lever with thegate is drawn upon, it will be seen that the strain, owing to the oblique position of the levers, is in the direction of lthe side ot' the triangle. This draws the pintle to thel Anext adjoining corner.

\V hen the gate is to be closed, and the other lever is pulled, the` piutle passes `to the third'coruer, and releases the gate from the stop.

It will be seen that, as the 'lever-chains hang alymost directly over thev axis ot' the road, and not at one side, as in other gates o'f this class.. They may. at all times, and under all circumstances, be within reach from a loaded vehicle, which they could not be if at the side of the road. Having thus described my invention, l What I claim as new, and `lesire to secure by Letters Patent, is- 1. The elbow-levers, composed ofthe arms E E and S S, when arranged to operate vsubstantially as shown and for the purposes set foi-th.

2. In combination with the triangular eye c and `elbow-levers the main or back post G, when the same isI set obliquely to the roadway, so as to form faces on which to'pivot the said levers, substantially as shown, and for the-purposes specitied.
