VISIONAL SPECIFICATION.
Improvements Appertaining to Burners for Incandescent Gas
Lighting.
We, WILLIAM RICHARD CLAY and BEN WALMSLEY, both of 12, Great Moor Street,
Bolton in the County of Lancaster, Engineers, do hereby declare the nature of this
invention to be as follows, that is to say:-
It relates more particularly to the burners for incandescent gas light-
ing of the class usually styled "by-pass burners" and wherein resilient or
spring bearings are used for supporting said burners, which as is well known, are
formed of only sufficient strength as to support such burners, so that when any extra
force or weight is brought to act upon them, they are readily pulled out of position
or otherwise damaged, and our said invention consists of the application of means
whereby it is rendered impossible for those lighting such lamps or turning the taps
to let the gas flow or shut it off from flowing to said burners, to so pull or otherwise
force the levers connected with said taps as to interfere with said bearings in
anyway to their detriment.
To attain this object, in accordance with one arrangement we employ a stop
piece which is slotted to allow the usual chains attached to the extending arms of
the tap's lever mounted on a burner of the by-pass type, to pass through it, while
it prevents enlargements, formed on said chains by the securing of any suitably
formed parts thereto, from descending below it, thus when the chain on either
side or arm has to be pulled or moved through a sufficient space to turn the tap,
it is arrested by the stop piece, which in this manner withstands all extra forces
above what are necessary to operate the tap, which is thus, together with the burner
to which it is attached, left undisturbed.
Instead of the stop piece above described, we may employ an additional lever
pivotted upon the fixed supports which carry the burner and its resilient bearings,
and this lever we may couple by chains or rods to the tap's lever, while we then
mount stop pieces for arresting the movements of this secondary lever in both
directions, or these stop pieces may be fixed or formed on the secondary lever to come
into contact with this lever's bearings on the desired position being reached.
Further, stop pieces may be secured to the fixed support and made to extend up
to the lever on the tap, but for neatness and simplicity we prefer the arrangement
first before described.

We, WILLIAM RICHARD CLAY and BEN WALMSLEY, both of 12, Great Moor Street,
Bolton in the County of Lancaster, Engineers, 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, that is to say:-
It relates more particularly to the burners for incandescent gas light-
ing of the class usually styled "by-pass burners" and wherein resilient or
spring bearings are used for supporting said burners, which as is well known, are
formed of only sufficient strength as will support such burners so that when any extra
force or weight is brought to act upon them, they are readily pulled out of position
or otherwise damaged, and our said invention consists in the application of means
whereby it is rendered impossible for those lighting such lamps or turning the taps
to let the gas flow or to shut it off from flowing to said burners, to so pull or otherwise
force the levers connected with said taps as to interfere with said bearings in
anyway to their detriment.
This object we attain by the devices hereinafter explained and as illustrated
by the accompanying sheets of drawings in which :-
Fig. 1 is an elevation of a street lamp with a portion shown as cut away so that
the resilient bearings for the burner and our improved attachment thereto may be
more clearly seen.
Fig. 2 is a sectional view on line ab of Fig. 1 and as seen from above.
Figs. 3, 4, 5 and 6 are similar views to Fig. 2 but illustrate the formation of our
improved attachment when used in connection with two, three, and four or more
burners respectively when same are supported or mounted in close proximity
with each other.
Fig. 7 is an elevation showing how our attachment when formed as illustrated
by Figs. 1 and 2 may be used in connection with two burners.
Figs. 8 and 9 are elevation and plan view respectively of a modified form of our
device.
Fig. 10 is an elevation also showing a modification in the formation of our
improved attachment.
Fig. 11 is an elevation showing our improved attachment constructed so as to
reach or extend into contact with the tap's operating lever thus dispensing with
certain parts as is hereinafter explained.
Fig. 12 is an elevation of a device whereby any excessive movement of the
burner is prevented by arranging it so as to come into contact with a stop-piece
that is entirely clear of the tap's operating lever.
Fig. 13 is an elevation illustrative of an incandescent burner mounted on resilient
bearings and a flexible tube for supplying gas to said burner together with our
improved attachment for operating as hereinafter explained.
Fig. 14 is a similar view to Fig. 13 but illustrates a well known modification in
the formation of the flexible tube or device through which the gas is supplied to
the burner, and is intended to show that our improved attachment may be used
in connection with these devices.
Fig. 15 is a drawing in detail showing how a modified form of our improved
attachment may be made.
Similar letters and figures of reference indicate similar parts throughout the
several views.

page_text: In Figure 1, the burner c is shown as being supported by a coiled supply pipe d
which forms its resilient bearings, while in Figs. 7, 8, 10 and 11 the resilient bear-
ings (which may be any, of the well known kind as a spiral or other class of spring)
are not shown, yet we would have it understood that the said burners c (which
also are only partly shown) are supported by resilient bearings (somewhat as is
shown by Figs. 13 and 14 wherein the springs S form these resilient bearings) while
their supply pipes e are of indiarubber or of other flexible or elastic substance or
substances and do not support the burners c.
To carry our invention into effect we construct a stop-piece f so that we may
secure it upon the fixed or rigid part g of the gas supply pipe g', its slot f¹ enabling
us to adjust it relatively with the lever of the tap k in order that its slot f² may
be in a suitable position for the chains (or these may be cords or the like) m m¹
secured to the outer ends of the lever h, to pass through it.
On these chains m m¹ we secure small hoops or balls n n which are too large to
pass through the slot f so that by securing them in the proper position on their
chains m m (one hoop say n, being in contact with the stop-piece f when the lever h
is in position shown by Fig. 1, at which time the hoop n is raised clear of it while
when the chain m¹ is pulled or forced down the hoop n' will descend into contact
with said piece f and the other hoop will be lifted from contact with it, the two
said positions of the lever h being the closed and open positions of their tap k or
vice versa it will be seen that it is impossible for any force greater than is necessary
to open the tap k to be transmitted thereto through the operating chains m m³,
since, when said chains are moved to open or close said tap k, on this being effected
any further movement of them is prevented and the extra force transmitted to
them is withstood by the stop-piece f.
The stop-pieces f shown by Figs. 3, 4 and 5 are respectively arranged to meet
the requirements when two, three and four burners are grouped together, while that
shown by Fig. 6 will answer the purposes of any one or all of these or even when
more than four burners are grouped together.
The arrangement shown by Fig. 11, wherein the stop-piece p is made to extend
so that the ends of the lever may come into contact with it, is a device whereby
the hoops n n may be dispensed with and yet the object of our invention is thereby.
attained.
In Fig. 7 an arrangement is illustrated of two burners c with their levers h
joined together by bars s s¹ so that only two chains m m¹ are required for operating
them, while the single stop-piece f will answer for both. Provided inconvenience
is encountered in the application of any of the stop-pieces above described, the pro-
jecting stop-piece y shown by Fig. 12 may be used, in which case, on the cord m er
m being pulled down the whole burner e descends so that its lower surface c¹ enters
the hollowed end y₁ of said stop-piece y and is thereby held securely in both the
vertical and lateral directions, while when the cord is released the resiliency of its
bearings raises said burner c so that its end c¹ is entirely clear of the stop-piece y
which is thus free to act as is desired of it.
Instead of the stop-piece f being used an extra levert may be employed while
a projecting piece u (see Fig. 8) arrests it in its extreme positions. Or projec-
tions (for over-hanging the supply pipe 9) may be formed on this lever tas
shown by Fig. 9, instead of the projecting piece u being employed, while by the
projecting arm the said levert may be operated as desired.
Or again instead of the lever t a simple lever we may be employed as shown by
Fig. 10, in which case, projections a¹ formed on the supply pipe g determine the
extent of the path through which the lever wo is permitted to be moved. Further a
similar result is attained by the stop link 3 mounted within the resilient bearing
spring 4 shown by Fig. 15, in which case on the burner being pulled down the
nut 5 comes into contact with the said link 3 and so prevents further motion,
while since the distance between the nut 5 and link 3 is only very little, it is im-
possible for the burner to be thereby jerked or unduly shaken.

page_text: Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. As an attachment for incandescent-gas-burners supported by resilient bearings
a stop-piece formed so that it may be rigidly secured in position, chains or cords secured
to the arms of the lever for operating the tap of said burner and hoops or other pieces
secured to said chains or cords substantially as set forth.
2. In combination with an incandescent-gas-burner supported by resilient bear-
ings, a stop-piece slotted to allow its adjustment, chains or cords secured to the lever
arms for operating the tap of said burner, and means secured on said chains or cords
for arresting same by coming into contact with the stop-piece substantially as set
forth.
3. In combination with two or more incandescent-gas-burners supported by
resilient bearings, a stop-piece formed so that the cords or chains from the lever
arms of the taps on said burner may pass therethrough, said chains or cords and
means secured on said chains or cords to come into contact with said stop-piece,
substantially as herein specified.
4. In combination with an incandescent-gas-burner supported by resilient bear-
ings, a stop-piece arranged to prevent said burner from descending too far or
moving in a lateral direction on its tap being opened or closed, and means secured
