ELISHA G. HOLDER, OF MARQUEZ, TEXAS, ASSIGNOR OF ONE-HALF TO
ALVERDA J. VESTAL, OF SAME PLACE.
GATE.
SPECIFICATION forming part of Letters Patent No. 564,281, dated July 21, 1896.
Application filed December 27, 1895. Serial No, 573,429, (No model.)To ca l Ivhols it 7ay concern:
Be it known that I,ELISHA G. HOLDER,a citi-
zen of the United States, residing at Marquez,
in the county of Leon and State of Texas, have
5 invented certain new and useful Improve-
ments in Gates; and I do declare the following
to be a full, clear, and exact description of the
invention, such as will enable others skilled in
the art to which it appertains to make and use
io the same, reference being had to the accom-
panying drawings, and to the letters of refer-
ence marked thereon, which form a part of this
specification.
My invention relates to improvements in
15 rotary gates; and it consists in certain novel
features of construction hereinafter described
and claimed.
In the annexed drawings, Figure 1 is a per-
spective view of my improved rotary gate.
20 Fig. 2 is a detail section of the same, and
Fig. 3 is a detail view showing the mechan-
ism for operating the latches by pedestrians.
In carrying out my invention I erect at the
opposite sides of the roadway the latch-posts
25 A, and at the center of the roadway I erect
the cylindrical pivot-post B, all of which posts
are firmly secured in the ground. The cen-
tral or pivot post B is provided at the surface
of the ground with a shoulder C, and its up-
30o per end is reduced, as shown at D. Fitting
loosely over the upper extremity of the pivot-
post is a beam E, which extends entirely
across the roadway between the latch-posts.
Depending from the ends of this beam E is
35 a pair of standards F, the lower ends of which
are connected by the rails or beams G, pass-
ing on opposite sides of the pivot-post and
free of said post. In order to give additional
rigidity to the structure, I secure to the stand-
40 ards the side rails H, which extend between
the upper ends of the same and serve as
guards to prevent the upper end of the pivot-
post being broken by shocks and blows to
which it maybe subjected. At proper points
45 between the pivot-post and the latch-posts
I secure to the beams E and G the braces I,
which converge downward and have their
lower ends resting on the shoulder C of the
pivot-post. It will thus be seen that the en-
50 tire weight of the gate is borne by the annu-
lar shoulder of the pivot-post through thebraces, and that it is supported from the top
so that it may be easily swung when unlatched
without necessitating the application of a
great force and unduly tiring the operator. 55
The beam E does not rest on the upper shoul-
der of the pivot-post, so that there is very lit-
tle friction thereon. The reduced upper end
of the said post serves to steady the gate and
furnish the necessary stay without weaken- 6o
ing the upper beam.
On the upper side of the beam E, I secure
the frame or box J, within which I pivot the
levers K, extending out from the gate and
running longitudinally of the roadway. The 65
longer or operating arms of the levers project
in opposite directions from the gate and are
connected with the shorter arms of the other
levers by the links L, as clearly shown. The
end of the shorter arm of each lever is fur- 70
ther connected by a connecting-rod M with a
latch N at the adjacent end of the gate, and is
supported by a vibratory brace 0, having its
upper end connected to the lever and its
lower end pivoted to the lower beam of the 75
gate, said brace serving to prevent sagging
of the lever and consequent twisting and
bending of the pivots. The latches N con-
sist of spring-rods rigidly secured at their
lower ends to the end standards of the gate 80o
and having their upper ends bent outward
and projecting through the said standards to
engage notches or keepers P in the latch-
posts. The resiliency of the spring - rods
keeps the latches normally in engagement 85
with the notches in the latch-posts, so as to
keep the gate closed, but when the levers are
swung toward the end of the gate the latches
are released and the gate may be opened.
The levers, it will be readily understood, pro- 90
ject some distance from the gate, so that per-
sons approaching the gate on horseback or
in a vehicle may open the gate without dis-
mounting.
Persons approaching the gate in a vehicle 95
or on horseback grasp the lever and push it
forward as they approach and pass through
the gateway. One half of the gate is thus
made to swing away from the path of the
passenger while the other swings around be- Too
hind him, so that when he has passed through
the gateway the gate will have made one-
