as follows:
The object of my invention is to provide by simple and efficient means for opening
5 and closing a gate from a distance by pressure or pull applied to suitably arranged parts
of the apparatus as I will now proceed to explain with the aid of the accompanying
illustrative drawings.
Referring to these drawings,
Fig. 1, shows in elevation (closed) a gate mounted so as to be operated according
C to my invention.
Fig. 2 is a corresponding plan.
Fig. 3 shows an elevation of the gate in its open attitude.
Fig. 3 shews the gate stop at right angles to Fig. 3.
Fig. 4 shows in side elevation on an enlarged scale the arrangement for supporting
5 the gate.
Fig. 5 is an elevation at right angles to Fig. 4.
Fig. 6 is a plan.
Fig. 7 is a sectional view of apparatus located at a distance from the gate and
which is connected by rod to the rod represented in Figs. 2 and 5 for the purpose of
O causing the gate to be opened in advance by a vehicle approaching it and afterwards
closed by the vehicle as it travels away from the gate.
Fig. 8 is an elevation partly in section at right angles to Fig. 7.
Fig. 9 is a plan.
Figs. 10, 11, and 12, indicate diagrammatically the relative positions of parts of
5 such an apparatus as above referred to corresponding to different positions of the
gate.
Figs. 13, and 14, are elevations at right angles to one another of apparatus for
operating the gate by hand from a distance.
Figs. 15, 16, and 17 show respectively elevations at right angles to one another
and a plan of an arrangement that may be substituted for that represented in
Figs. 4 to 6 inclusive.
Referring to Figs. 1, 2, 3, 4, 5 and 6, it will be seen that the lower hinge pin 1 of
the gate 2 is carried by an arm 3 fixed on a pin 4 able to rotate in a bracket 5
attached to the gate post and which pin 4 has fast on its lower end a second
5 arm 6 to which the operating gear is connected.
To the free end of the upper
arm 3 is connected one end of a chain 7 which passes between guide rollers 8
and whose other end is attached to a weighted lever 9 which tends to keep the arm 3
in or to return it to the attitude corresponding to the closed position of the
gate.
The dotted positions of the arms 3 and 6 indicated in Fig. 6 correspond to open
positions of the gate.

page_text: 10 is a rod shown slotted at 10" and connected by a pin to the free end of the
arm 6 so as to operate that arm when the rod is moved longitudinally in either
direction. The rod 10 is jointed or connected to gear located at a distance and
adapted to impart to it the required longitudinal movements as I will now explain;
premising. that to the end of arin 6 might simply be jointed the ends of two
separate operating rods (see Fig. 6^).
Referring to Figs. 7 to 12 inclusive 11 is a rod with crank 12 normally (i.e. when
the gate is shut) occupying its uppermost position as represented in Figs. 7, 8 and 9,
in which it projects above the roadway so as to be acted upon by wheels of a passing
vehicle 13 is a counter-weight tending to keep the crank in or to return it to its raised
position. 14 is an arm fixed on the rod 11 and provided with an anti-friction roller 15.
16 and 17 are lever arms able to rotate about the axis 18, the lever arm 17 being
jointed to the rod 10b which is connected to the before mentioned rod 10. 19 and 20
are other lever arms able to turn about the axis 21; the arm 20 is also jointed to the
rod 10b.
The positions represented in Figs. 7 to 9 and in Fig. 12 correspond to the closed
position of the gate. Now assuming the crank 12 to be depressed by the wheels of
a vehicle travelling from left to right (see the arrow marked A) then the arm 14 will
be brought into contact with the arm 16 and the latter will be depressed into the
position represented diagrammatically in Fig. 11 so that by the corresponding pull
upon the rod 10h the gate will have been opened.
Assuming a duplicate arrangement of operating gear to be located at the opposite
side of the gate then the arms 16, 17, 19, and 20 of that duplicate operating gear
will have been caused to assume the positions indicated to the right in Fig. 11. Then
after the vehicle shall have passed through the gateway if its wheels depress the
crank 12 of the second set of operating gear the effect will be to cause the arm 14
thereof to act upon the arm 19 in such wise as to depress it into the position
represented to the right in Fig. 12 thereby through the rods closing the gate
and so on, as will be evident. If it be desired to operate the gates from a
distance by hand this may be effected by an arrangement such as represented in
Figs. 13 and 14 comprising a post 22, a lever 23 pivotted at 24 and provided
with a pull 25 connecting the rod 26, the bell crank lever 27 pivotted at 28
and the connecting rod 10.
In the modification shown in Figs. 15 to 17 inclusive the hinge pin 1 of the
gate is connected to the rod 10 and the bracket 5 is formed with a doubly
inclined slot 29 so that if the rod 10 be moved end-wise in either direction the
effect will be to cause the pin 1 to travel along the correspondingly inclined side of
the slot 29 so causing the gate at its outer or free end to rise and also giving it more
or less of a side wise tilt in such a manner as to cause it to open. In Fig. 17
the position of the parts represented correspond to the closed position of the
gate.
The details of construction may be varied more or less to suit circumstances.
I, ROBERT EDWIN DOWNING RUDMAN, of Old Road, Chippenham, in the County of
Wilts, Builder and Contractor, do hereby declare the nature of this invention and 50

page_text: in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The object of my invention is to provide by simple and efficient means for opening
and closing a gate from a distance by pressure or pull applied to suitably arranged
parts of the apparatus as I will now proceed to explain with the aid of the illustrative
drawings filed with my Provisional Specification.
Referring to these drawings,
Thoms in slauation an
Fig. 6 is a detail view.
Fig. 7 is a sectional view of apparatus located at a distance from the gate and
which is connected by rod to the rod represented in Figs. 2 and 5 for the purpose of
causing the gate to be opened in advance by a vehicle approaching it and afterwards
closed by the vehicle as it travels away from the gate.
Fig. 8 is an elevation partly in section at right angles to Fig. 7.
Fig. 9 is a plan.
Figs. 10, 11, and 12, indicate diagrammatically the relative positions of parts of
such an apparatus as above referred to corresponding to different positions of the
gate.
Figs. 13, and 14, are elevations at right angles to one another of apparatus for
operating the gate by hand from a distance.
Figs. 15, 16, and 17 show respectively elevations at right angles to one another and
a plan of an arrangement that may be substituted for that represented in Figs. 4 to 6
inclusive.
Referring to Figs. 1, 2, 3, 4, 5 and 6, it will be seen that the lower hinge pin 1 of
the gate 2 is carried by an arm 3 fixed on a pin 4 able to rotate in a bracket 5 attached
to the gate post and which pin 4 has fast on its lower end a second arm 6 to which
the operating gear is connected. To the free end of the upper arm 3 is connected one
end of a chain 7 which passes between guide rollers 8 and whose other end is attached
to a weighted lever 9 which tends to keep the arm 3 in or to return it to the attitude
corresponding to the closed position of the gate.
The dotted positions of the arms 3 and 6 indicated in Fig. 6 correspond to open
positions of the gate.
10 is a rod shown slotted at 10ª and connected by a pin to the free end of the arm 6
so as to operate that arm when the rod is moved longitudinally in either direction.
The rod 10 is jointed or connected to gear located at a distance and adapted to impart
to it the required longitudinal movements as I will now explain; premising that to
the end of arm 6 might simply be jointed the ends of two separate operating rods
(see Fig. 6A).
Referring to Figs. 7 to 12 inclusive 11 is a rod with crank 12 normally (i.e. when
the gate is shut) occupying its uppermost position as represented in Figs. 7, 8, and 9,
in which it projects above the roadway so as to be acted upon by wheels of a passing
vehicle, 13 is a counterweight tending to keep the crank in or to return it to its
raised position. 14 is an arm fixed on the rod 11 and provided with an anti-friction
roller 15. 16 and 17 are lever arms able to rotate about the axis 18, the lever arm 17
being jointed to the rod 10b which is connected to the before mentioned rod 10. 19
and 20 are other lever arms able to turn about the axis 21; the arm 20 is also jointed
to the rod 10b.
The positions represented in Figs. 7 to 9 and in Fig. 12 correspond to the closed

page_text: position of the gate. Now assuming the crank 12 to be depressed by the wheels of a
vehicle travelling from left to right (see the arrow marked A) then the arm 14 will be
brought into contact with the arm 16 and the latter. will be depressed into the position
represented diagrammatically in Fig. 11 so that by the corresponding pull upon the.
rod 10 the gate will have been opened.
.
Assuming a duplicate arrangement of operating gear to be located at the opposite
side of the gate then the arms 16, 17, 19, and 20 of that duplicate operating gear will
have been caused to assume the positions indicated to the right in Fig. 11. Then
after the vehicle shall have passed through the gateway if its wheels depress the
crank 12 of the second set of operating gear the effect will be to cause the arm 14
thereof to act upon the arm 19 in such wise as to depress it into the position repre-
sented to the right in Fig. 12 thereby through the rods closing the gate and so on,
as will be evident. Fig. 10 shews the position the parts will first be moved into by a
vehicle travelling from right to left, (in which position the gate is open) and from
which the parts will be moved into the position shewn in Fig. 12 on the vehicle in
its further travel acting on the lever arms at the left hand side of the figure.
If it be desired to operate the gates from a distance by hand this may be effected
by an arrangement such as represented in Figs. 13 and 14 comprising a post 22, a
lever 23 pivoted at 24 and provided with a pull 25ª connecting the rod 26, the bell
crank lever 27 pivoted at 28 and the connecting rod 10.
In the modification shown in Figs. 15 to 17 inclusive the hinge pin 1 of the gate
is connected to the rod 10 and the bracket 5 is formed with a doubly inclined slot 29
so that if the rod 10 be moved end-wise in either direction when the gate is closed
the effect will be to cause the pin 1 to travel along the correspondingly inclined side
of the slot 29 so causing the gate at its outer or free end to rise and also giving it
more or less of a side wise tilt in such a manner as to cause it to open. In Fig. 17
the position of the parts represented correspond to the closed position of the gate,
and the hinge pin is supposed to be provided with a weighted lever that tends to keep
the parts in the attitude corresponding to the closed position. To close the gate the
hinge pin is moved along the slot to its initial position thus tilting the gate in the
opposite direction and raising its free end, which during the swinging open of
the gate has dropped as indicated in Fig. 3.
The accompanying drawings illustrate a modification of the arrangement illustrated
in Figs. 15 to 17 of the drawings filed with my Provisional Specification.
Fig. 18 is a front view;
Fig. 19 a side view; and
Fig. 20 a plan of as much of the apparatus as is necessary to illustrate this way of
carrying out my invention.
The bracket 5 is formed with an inclined slot 29 and has fitted beneath it a sliding
bar 30 that is formed with a transverse slot 31 through which the hinge pin 1 of the
gate depends. To the ends of the bracket are pivoted weighted balance levers 32
which are bent and so arranged that their approximately upright portions bear against
studs or pins 33 that project rearwardly from the bar 30 and thus tend to keep it in
its middle position, and consequently the gate in its closed position. To each end of
the bar 30 is attached a chain or wire rope by means of which the bar can be moved
in either direction, whereby the pin 1 will be caused to travel along the inclined side
of the slot, 29, the transverse slot 31 allowing it to move outward freely, and so open
the gate.

the gate post and in which is rotatably fixed a vertical pin provided at each of its ends
with an arm the upper one carrying the hinge pin 1 of the gate and the lower one
being adapted to be moved so as to open or close the gate through a rod or rods

page_text: operated by apparatus such as shewn in and described with reference to Figs. 7, 8 and 9
or to Figs. 13 and 14 of the drawings filed with my Provisional Specification,
substantially as shewn and described.
2. Gate opening and closing apparatus comprising a bracket formed with a doubly
inclined slot, a hinge pin and means by which the one may be moved endwise in
either direction relatively to the other thereby tilting the gate sidewise and causing
its free end to rise so as to cause the gate to open or close, substantially as described.
3. In gate opening and closing apparatus the combination of weighted cranked
rod 11, 12 arm 14 levers 16, 17 19 and 20 and rods 10 and 10 for the purpose
mentioned the arrangement being such that, according to the direction in which a
vehicle is proceeding the said apparatus will, operate either to open or to close the
gate, substantially as described.
4. Gate opening and closing apparatus substantially as shewn in and described
with reference to Figs. 1 to 6 and Figs. 7 to 9 of the drawings or as modified according
to Fig. 6, or to Figs. 15 to 17 of the drawings filed with my Provisional Specification
or according to the drawings hereto annexed.
