page_text: I ROBERT JOHN WORRALL of The Iron Gate Works 24 Byrom Street, &
9 Cuerdon Street, Liverpool in the County of Lancaster Designer & Art Metal
Worker do hereby declare the nature of this invention to be as follows:-
According to my invention I arrange the punctured bars of a fence longitudin-
ally approximately horizontal, and latterally inclined and I may arrange a number
of my bars that pass through the punctures vertical and in such relation to each
other and to the punctured bars as that open spaces are formed.
I may fill these open spaces with plates of metal, glass or other material suited
to the filling up of such spaces.
In order to prevent the withdrawal of a vertical bar from its connection with my
fence I form upon one or both ends thereof a neck and shoulder.
I thrust the neck through a puncture in a related bar and on the plane of the
iaiter opposite to the shoulder I form a rivet head.
Or I cause the direction of the punctures in one or more of my punctured metal
bars to be at or nearly at right angles to the general direction of the bars which
pass through the punctures. And in one or more portions of these latter bars I
change their direction so that it describes a crank, or U form, having parts at
or nearly at right angles to each other.
Thus I slide or hook a bar into its related puncture and rotate it laterally into
such relation thereto that one portion of it is within the puncture and that
opposite portions of it are without the puncture.
And that the direction of the opposite portions of it without the puncture are at
or nearly at right angles to the direction of the portion within the puncture.
And that the opposite portions without the puncture are against opposite planes
of the punctured bar.
Or I cause the direction of the punctures to be parallel to or in line with the
general direction of the bar which passes through.
And in one or more portions of this latter I may change its direction so that it
describes a double crank form, having several parts at or nearly at right angles to
each other. Thus I slide or hook a bar into its related puncture and radiate it
longitudinally into such relation therewith that one portion of it is within the
puncture and that opposite portions of it are without the puncture.
And that the direction of the opposite portions of it without the puncture are at
or nearly at right angles to the direction of the portion within the puncture and
that the opposite portions without the puncture are against opposite planes of the
punctured bar.
And yet that the direction of the remaining part remains parallel or nearly
narallel to the direction of the puncture.

page_text: I may further crank, set or curve the bar or bars which pass through punctures
so that they occupy given planes and form the required relationship with other
parts of the fence."
Or or and I prevent the withdrawal of a metal bar from its connection with my
fence by causing it to pass through a puncture in a related metal bar, having
within it a groove or grooves preferably spiral and by forming without the bar
corresponding groove or grooves, and in such relationship that a keyway or key-
ways are formed. Into these I insert keys generally of metal while in the molten
state. Or to the same end I so incline cr otherwise arrange my punctured bars
that the wall or walls of the punctures enter notches or grooves prepared to receive
them and formed in the bar which passes through the puncture. I may however
connect a series of metal bars with metal bars approximately at right angles
therewith by forming in the latter dovetail punctures preferably countersunk on
each side and on the ends of the former a dovetail head slightly greater laterally
than the related dovetail puncture I place the dovetail head within the dovetail
puncture and spread by pressure until it form a rivet. In order to accomodate
my Bars to ground that is inclined ramped or stepped or or and to their inter-
section at various angles and to facilitate the adjustment thereof to such angles I
connect the bars at their intersection by any detachable hinge. In order to open
a fence or any portion of it, so as to admit goods or passengers, or to protect an
opening therein I introduce any suitable gate or door. I slide the same laterally
and to this end I use in a horizontal position and running laterally from the
principal plane of my fence or the opening fenced any of the Guides described in
my Specification of Patent No. 2195, 1893 and illustrated in the drawings there-
with by Figure 4, 5, 6, 7, 8, 9. In such case I suspend my Gate or door from its
guides and cause it while preserving its parallel relation to the principal plane of
my fence or the opening fenced to slide in a direction at right angles therewith
or I cause my gate or door to rotate upon hinges. In such case I form the axle of
my hinge conical and the bush in which it fits correspondingly conical I form a
space between axle and bush and therein may insert friction balls or rollers or I
may form my gate or door as described in my Specification of Patent No. 2195,
1893 from line No. 34, page 3 to line No. 27 page 4 both inclusive.
I may arrange that the height of my fence or its door or gate reduced by teles-
coping as described in my Specification of Patent No. 2195, 1893 lines 34 & 35
page 3, be in such relation to the ground and the height therefrom of the floor of
a vehicle that while it form a fence to persons it permits loads of goods slung by a
hoist or the like to pass over it to and fro such vehicles.
To this same end I may fix one or more leaves rigid and one or more leaves
hinged and above the rigid leaves and free to rotate within a segment on a hori-
zontal axis and to move out of the path of a load of goods slung by a hoist, over 'the
leaf or leaves fixed rigid.
The movement of the hinged Icaf to be actuated by the hoist or otherwise I
form an aperture in or under the rigid leaf to accommodate the feet of the Hoist-
man and allow him to draw near & bend over the fence or Gate or door of same.
I may dispense with the rigid leaf & fix the hinged leaf to a fixed support and
free to rotate & move out of the math aforesaid.
I may so connect the bars of my fence with hinges that they may slide horizon-
tally or vertically and fold and pack closely together and be drawn apart & held so at
given distances & to accomodate them in the change in their relationship caused by
the movements of the hinge I may cause one portion of a bar to slide telescopic-
ally into another portion or I may connect my hinge to any or all of my bars by
means of a sliding collar.
In order the better to resist lateral strains I set my hinge with its lesser plane
towards the eye.

I, ROBERT JOHN WORRALL of the Iron Gate Works Cuerden Street and
24 Byrom Street, Liverpool in the County of Lancaster Designer, Gatesmith, and
Art Metal Worker, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
The words and numbers herein contained refer to drawings herewith and like
letters refer to like parts on the said drawings.
Figs. 1, 7, 23, 31, 33, 34, 35, 36, 37, 39, 45, 46, 53, 54, 61, 62, 65, 17 are
elevations.
Figs. 10, 11, 12, 16, 71, 79 are elevations enlarged.
Figs. 13, 32, are side elevations.
Figs. 81, 78, 9, 18, are end elevations.
Fig. 82 is sectional elevation.
Figs. 24, 25, 26, 27, 48, 58, 59 are part elevations enlarged.
Figs. 2, 3, 4, 5, 6, 8, 38, 66, 67, are plans.
Figs. 50, 51, 52, 72, are plans enlarged.
Figs. 43, 49, 57, 60, 73, are plan sections enlarged.
Figs. 14, 15, 19, 20, 21, 22, 28, 29, 30, 40, 41, 42, 44, 47, 63, 64, 80 are sections
enlarged.
According to my invention I arrange the punctured bar or bars A Fig. 1 pre-
ferably or rolled metal approximately horizontal and laterally inclined Fig. 18,
& I arrange the bars B which pass through the punctures preferably of rolled
metal vertical.
The punctured bars and the bars which pass through the punctures being in
such relation to each other as that open spaces C Fig. 1 arc formed.
I may fill these open spaces C with plates D Fig. 7, 9, 5, 8 of metal, glass or
other material suited to the filling up of such spaces and may pack/the spaces Y
Fig. 18 formed by the inclination of my punctured bar with any suitable pack-
ing Z, Fig. 9 and may add further to the weather resistance of my punctured bar
by adding thereto the parts A2, B2. Fig. 19 and may in such case omit the lateral
inclination.
In order to prevent the withdrawal of a vertical bar B from its connection with
my fence, I form upon one or both ends thereof a neck E Fig. 10 and shoulder F,
Fig. 10.
I thrust the neck E, Fig. 12 through a puncture G, Fig. 11 in a related bar H
and on the plane J Fig. 12 of the latter opposite to the shoulder F, Fig. 12 I forin
a rivet head K, Fig. 12 or I cause the direction of the punctures in one or more of
my punctured bars to be at or nearly at right angles to the general direction of the
bars which pass through the punctures and in one or more portions of these latter
bars, I change their direction so that it describes a crank P, N, O, Fig. 14, or
U form Q, R, S, Fig. 44 having parts at or nearly at right angles to each other
Fig. 13, 14, and 44. Thus I slide or hook a bar Binto its related puncture M,
Figs. 14, 44 and rotate it laterally into such relation thereto that one portion of
it N, Fig. 14, R2, Fig. 44 is within the puncture M and that opposite portions of
it O, P, Fig. 14, S2, Q2, Fig. 44 are without the puncture M and that the direction
of the opposite portions of it O, P, Fig. 14, S2, Q, Fig. 44 without the puncture M are
at or nearly at right angles to the direction of the portion N, Fig. 14 R2 Fig. 44
within the puncture and that the opposite portion O, P, Fig. 14, S2, Q2, Fig. 44,
without the puncture are against opposite planes R, S, of the punctured bar, or I

page_text: cause the direction of the puncture Z, Fig. 16 to be parallel to or in line with the
general direction of the bar B which passes through.
And in one or more portions of this latter bar BI may change its direction so
that it describes a double crank, form Fig. 17 having several parts U, V, W, X
at or nearly at right angles to each other. Thus I 'slide or hook a bar B, Fig. 17
- into its related puncture T, Fig 16 and rotate it laterally or longitudinally into
such relation therewith that one portion of it W is within 'the puncture T and
that opposite portions of it V, X, are without the puncture T. And that the
direction of the opposite portions of it V, X, without the puncture T are at or
nearly at right angles to the direction of the portion W within the puncture T
and that the opposite portions V, X, without the puncture T are against opposite
planes Y, Z, of the punctured bar.
And yet that the direction of the remaining part U remains parallel or nearly
parallel to the direction of the puncture T.
Or I cause the bar B, Fig. 15 to be formed at its lower end, as at B¹ and to pass
through the punctures C, D, in the punctured bar E which latter has
plates F, G, approximately at right angles to each other. It will be readily seen
that any bar B treated as shewn by Figs. 13, 14, 16, 17, 33, 44 or similarly
permits of more or less rotation longitudinally with the fence, and is therefore
capable of being set at various angles longitudinally and that while sustained by
the support J Fig. 13, 33 or similar support in any of the relationships with a
punctured bar or bars shewn at Figs. 13, 14, 15, 16, 33, 44 it is locked in the
puncture and cannot be withdrawn from, its connection witli the fence and that it
may be unlocked and withdrawn therefrom when released and rotated in a given
direction to a given angle.
It will be seen further that I may make other modifications in my treatment of
the bar B which would answer my purpose of causing it to be locked in its puncture
by the action of rotation laterally or longitudinally and that various sections of
punctured bars and various forms of punctures will answer my purpose as also the
movement of the punctured bar in place of that of the bar B or the invertion of
the described arrangements.
I may further crank set or curve as at A¹ Fig. 14, P2 Fig. 44 the bar or bars B
which pass through punctures so that they occupy given planes, and form the
required relationship with other parts of the fence and I may serrate my punctured
bar as at Figs. 65, 66, 67, or, or and I prevent the withdrawal of a metal bar B
Fig. 40, 41, from its connection with my fence by causing it to pass through a
puncture H, Fig. 20, 21, in a related metal bar Ji having within it a groove or
grooves K' Fig. 20 preferably spiral L¹ Fig. 21 and by forming without the bar B,
Fig. 40, 41, corresponding groove or grooves M, Fig. 40 or N Fig. 41, and in such
relationship that a keyway or keyways are formed.
Into these I insert keys generally of metal while in the molten state.
Or to the same end I so incline or otherwise arrange my punctured bars that
the wall or walls of the punctures enter notches or grooves 0 Fig. 22 prepared to
receive them and formed in the bar B which passes through the puncture O
Fig. 22.
13
I may however connect a series of metal bars with metal bars P, Q, Fig. 23
approximately at right angles therewith by forming in the latter P, Q, dovetail
punctures R, Fig. 24 preferably countersunk on each side and on the ends of
the former B, Fig. 25 a dovetail head S Fig. 25 slightly greater laterally than the
related dovetail puncture R¹ Fig. 24. I place the dovetail head S Fig. 25 within
the dovetail puncture R¹ Fig. 24 and spread by pressure until it form a rivet.
Or I adopt a triangular cross section solid or hollow as is ordinary angle-iron
for my bars B and I may form a dovetail puncture in one or several of my bars A
as in Fig. 43 thus I am able to slide my bar B into the puncture in my bars A
and whether I arrange the bars A horizontal or vertical the bar B cannot be with-
drawn laterally from its connection therewith.
In order to accomodate any of my bars such as B, J, Fig. 13, B 26, Ja, 27, A, B

page_text: Fig. 1 to ground that is inclined, ramped or stepped or, or and to their intersection
or meeting with each other, or with other bodies at various angles and to facilitate
their adjustment to such angles I connect them at their intersection or meeting by
any detachable hinge such as T', Fig. 26, 27, T2, Fig. 59, 60 & I provide spaces
such as U2 for expansion.
In order to open a fence or any portion of it so as to admit goods or passengers,
or to protect an opening therein I introduce any suitable gate or door. I slide the
same laterally and to this end I use in a horizontal position & running laterally
from the principle plane of my fence or the opening fenced any of the guides
described in my Specification of Patent No. 2195, 1893, and illustrated in the
drawings therewith by Figures 4, 5, 6, 7, 8, 9, 10. In such case I suspend my
gate or door from its guides and cause it while preserving its parallel relation to
the principal plane of my fence, or the opening fenced to slide in a direction at
right angles therewith.
Or I may form my gate or door as described in my Specification of Patent
No. 2195 1893 from line No. 34 Page 3 to line No. 27 Page 4 both inclusive.
When my gate or door formed with my bars A or J2 and B or otherwise, rotates
upon hinges I form a portion of the axle U Fig. 28, 29, 30, of my hinge conical
and the bush VI in which it fits correspondingly conical I form a space W between
axle and bush and therein insert friction balls or rollers X¹.
I may arrange that the height of my fence or its door or gate constructed with
my bar A or 2 and B or otherwise reduced by telescoping as described in the
lines 34, 35, of my Specification of Patent No. 2195, 1893 be in such relation to
the ground and the height therefrom of the floor of a vehicle that while it form a
fence to persons it permits loads of goods slung by a hoist or the like to pass over
it to and fro such vehicles. To this same end 1 may fix one or more leaves C2,
Figs. 31, 32, rigid and one or more leaves D2 Fig. 31, 32, hinged and above the
rigid leaves and free to rotate within a segment such as E, F, on a horizontal
axis G2 and to move out of the path of load of goods slung by a hoist or the like
over the leaf or leaves C2 fixed rigid.
For it will be evident that a load of goods may be so slung or suspended from a
cathead or other central point or axis above my fence, and caused so to swing to
and fro within the radius of my hinged leaf that it collide therewith and thus force
it to rotate upon its hinges and out of the path aforesaid.
I form an aperture H2 in or under the rigid leaf to accomodate the feet of the
hoist-man and allow him to draw near and bend over the fence.
I may dispense with the rigid leaf C2 and fix the hinged leaf D² to a fixed
support and free to rotate and move out of the path aforesaid.
Again in order to open a fence or any portion of it so as to admit goods or
passengers I so connect the bars B with hinges K2 Fig. 34, 35, 36 that they may
slide horizontally or vertically and fold and pack closely together Fig. 37 be drawn
apart and held so at given distances.
And to accommodate them in the change in their relationship caused by the
movement of the hinge I may cause one portion of a bar to slide telescopically into
another portion L, Fig. 36.
Or I may connect my hinge to any or all of my bars by means of a sliding
collar M Figs. 34, 37 or to the same end I form in my bar B one or several slots G³
Figs. 81, 82 & therein fit one or several wheels or rollers D³ preferably having a
grooved periphery in which the sides of my slot fit.
To this or these wheels or rollers I pivottally attach a portion of my hinge so
that it is free to move along my Bar B, and the 'friction resulting from such
motion is reduced and the hinge is held in position laterally with my fence by
means of the wheel or roller D and the groove E3 in the periphery of the latter
lolds my hinge in its position longitudinally with my fence when my bar B is
vertical and in its position vertically with my fence when my bar B is horizontal.
When several of my bars B are joined by my hinges K2 I place the described

page_text: wheel or roller between two of my hinges K and working in the slot and the
bar B.
Or in place of the wheel or roller I may use a packing piece of any suitable
form to work in the slot C3 and with or without the groove E³ and attach thereto
my hinge or hinges K2 on one or both sides thereof.
In order that the general plane of my fence may the better resist lateral strains
I set my bars B, or, or and my hinge 2 Figs. 38, 39 both having unequal planes
with their lesser planes N2 Figs. 38, 39 parallel or in line with the general plane of
my fence, and to the same end I may adopt the knuckle form of hinge with its
axis running laterally or at right angles with the general plane of my fence or
I form the joint of my hinge by connecting the parts Fs Figs. 71 and 72 with my
bars B the latter being duplicated laterally Figs. 73, 79.
Further in order to open my fence so as to admit goods or passengers I connect
my bars B with my punctured bars as described and shown in Figs. 14, 44 or more
particularly at Figs. 63, 64, 61.
Or I connect my bars B with bars of any suitable section the angle form pre-
ferred, Fig. 49, 47 by means of studs V attached to my bar B by means of a
collar W Figs. 45, 47, 49 and attached to my bar of suitable section, angle form
preferred Figs. 47, 49, by means of a screw passing through a puncture and being
secured by a mut or by rivetting Figs. 47, 49.
Thus my bars Bare pivottally connected Figs. 47, 49, 45, 64, 63, 61, with bars
of suitable section which latter are free to rotate upon the hinges X, Y Figs. 48,
51, 45, 50, 52 and may be collapsed as shown by Figs. 46, 62.
It is often desirable that the opening portion or the protection to the opening
portion of a fence please the eye.
Those in common use which are capable of folding collapsing, or closing
together as shown in Figs. 61, 34, 37, 35, 36, do not so please and in order that
they may so please, and as ornament cannot be placed between the bars which fold
together I attach such ornament as 7 Fig. 53 by means of a lug A³ attached to or
integral with my bars B and so that my bars B may juxtapose on one of the
principal planes of the ornament Fig. 54.
Further I may attach ornament as B³ to the top horizontal bar as in Fig. 61, 62
which will permit the bars B to juxtapose as at Fig. 62.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:-
I. In a fence a series of rolled metal bars B of any cross section passing through
punctures in a series of laterally inclined rolled metal bars A forming the space C
