PATENT OFFICE.HIRAM TERRY, OF HEREFORD, TEXAS.
GATE.SPECIFICATION forming part of Letters Patent No. 733,684, dated July 14, 1903.
Application filed January 16, 1903, Serial No. 139,311. (No modeL)To all whom it ntay concern:
Be it known that I, HIRAM TERRY, a citizen
of the United States, residing at Hereford, in
the county of Deaf Smith and State of Texas,
; have invented a new and useful Gate,of which
the following is a specification.
My invention relates to gates, and is espe-
cially directed to gates which are adapted to
swing downward from a vertical to a horizon-
mo tal position and lie flush with the surface of
the ground in position for a vehicle to pass
over the same, and has for its object to pro-
vide a simple and efficient mechanism oper-
ated, preferably, by the wheels of a vehicle
15 to positively move the gate from its closed to
its open position, and vice versa.
The invention comprises the details of con-
struction and combination of parts more fully
hereinafter described.
20 In the accompanying drawings, Figure 1 is
a perspective view of the device. Fig. 2 is a
top plan view of the same.
Referring to the drawings, 1 indicates a
gate of any suitable construction, but prefer-
25 ably comprising end posts 2 and 3 and a cen-
ter post 4, having wires stretched between the
posts. The posts are pivoted at their lower
ends and adapted to swing upon horizontal
pivoting-rods 5, journaled in or otherwise se-
30 cured to horizontal base plates or beams 6,
fixed in any suitable manner at the surface
of the ground. The pivotal rods 5 project
laterally beyond the posts longitudinally of
the gate and are provided with suitable heads
35 for the purpose to be hereinafter described.
7 indicates a horizontal rod which extends
at right angles to the gate adjacent to the cen-
tral post 4 and is sustained for rotation in
suitable bearings 8. Mounted on the rod for
40 rotation thereby is a beveled gear 9, in mesh
with a similar gear 10, fixed in any suitable
manner to the lower end of the central gate-
post 4. 11 and 12 indicate bevel-pinions
mounted at the ends of the rod at opposite
45 sides of the gate and at a suitable distance
from the gate.
13 and 14 indicate two operating members
situated one at either side of the gate adja-
cent to the respective ends of the rod 7. Each
50 of these operating members comprises a short
shaft 15, mounted for rotation in a suitable
bearing 16 and provided at each end with afixed wing or blade 17 or 18, which lie, respec-
tively, in the path of passing vehicles in po-
sition to be actuated by the wheels thereof in 55
the manner and for the purpose hereinafter
explained.
19 indicates a bevel-pinion mounted on the
shaft 15 in mesh with the pinion at the end
of the shaft 7 and adapted when the shaft 15 6o
is rotated by the vehicle-wheels striking either
of the blades 17 or 18 to rotate the shaft 7 and
through the medium of the gears 9 and 10
positively swing the gate on its pivot from an
open to a closed position, or vice versa. 65
20 is a lever pivoted at 21 and lying in a
plane parallel with the longitudinal direction
of the gate. This lever is connected at its
inner end with a pulley 22, around which
passes a cable or the like 23, connected at its 70
ends to the upper and lower ends of the post
3. The opposite or outer end of the lever is
provided. with a suitable weight 24, which ex-
erts a pressure on the lever and causes the
same.to exert a suitable tension on the gate 75
through the medium of the pulley and cable,
and thus maintain the same in its normally
closed position,except when positively opened
by the mechanism above described. 25 is a
similar cable connected to the upper and 8o
lower ends of the post 2 and engaged between
its ends with a fixed stop 26 and serving, as
will be readily understood, to equalize the
tension on the gate exerted by the weight and
its attendant mechanism. Should the cable 85
25 become slack owing to expansion or other
causes, the gate is susceptible of a slight
movement in the direction of its length along
the extended pivots 5, thus permitting the
weight to move the gate and compensate for 90
such slack and maintain at all times the
proper tension.
In operation, supposing the parts to be in
the position illustrated in Fig. 1 and a vehi-
cle to be approaching the gate from the left, 95
the vehicle-wheel will come in contact with
the blade 17 and turn the same from a verti-
cal to a horizontal position, thus rotating the
shaft 15 and imparting motion therefrom
through the medium of gear-pinions 19 and 'Co
11 to the shaft 7. The shaft 7 in rotating will,
through the medium of gears 9 and 10, serve
to positively swing the gate downward until
it has passed the center of and falls by grav-
