PROVISIONAL SPECIFICATION.
Improvements in or relating to Balanced Covers for Jugs or
other Vessels.
I, CHARLES CLARKE BRUFF of Coalport in the County of Salop, China
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in or relating to balanced covers for jugs
or other vessels.
Jugs or other vessels fitted with balanced covers, are generally formed upon each
side of the mouth with an open-ended inclined slot, to receive corresponding
studs or axes carried by the lid, but these means of connection are not so secure
as is desirable, added to which the inclined slots are difficult and expensive to
produce.
Now the objects of my invention are to render the cover capable of ready
connection and disconnection with the jug or other vessel, and to simplify that part
of the connecting means carried by the jug.
For this purpose upon the under side of the balanced cover in suitable bearings
arranged transversely thereof, I mount with capability of sliding a long bolt or
spindle, and I connect this sliding bolt or spindle through a transverse slot formed
in the cover with a knob or button located upon the upper side of the cover and
furnished with a covering plate to conceal the slot.
The sliding bolt or spindle is so connected with the knob or button, that in one
position of the bolt, both ends thereof project an equal distance beyond the cover,
whilst in the other position one end is entirely retracted beneath the cover, whilst
the other end is correspondingly further projected, and this sliding bolt constitutes
that part of the connecting means which is carried by the cover.
The other part of the connecting means carried by the jug or other vessel consists
of two small holes formed therein one upon each side of the mouth. thereof near to
the lip or top edge, and in true alignment with each other, and these holes may
either be formed previous to firing the jug or other vessel or subsequently by drilling
as may be found most convenient, the operation in either case being of a simple and
inexpensive character.
The holes in the jug constitute bearings for the ends of the sliding bolt or spindle,
and the cover
placed in position by retracting the bolt or spindle, tilting the cover
to one side, inserting the doubly projecting end of the bolt or spindle in one hole or
bearing, then lowering the cover to a horizontal position and by the aid of the knob
or button, shooting the retracted end of the bolt or spindle into the corresponding
hole or bearing, & spring or other stop being employed to prevent the accidental
sliding back of the bolt or spindle.
According to a modified arrangement, I dispense with the sliding knob or button,
and substitute therefor, a turn button which gives motion to the sliding bolt or
spindle through a cam or eccentric.
According to a further modification I divide the bolt or spindle transversely
into two parts, and give motion to both parts by means of a turn button or
the like.

Improvements in or relating to Balanced Covers for Jugs or
other Vessels.
I CHARLES CLARKE BRUFF of Coalport in the County of Salop China
Manufacturer 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 :-
My invention relates to improvements in or relating to balanced covers for jugs
or other vessels.
Jugs or other vessels fitted with balanced covers are generally formed upon each
side of the mouth with an openended inclined slot to receive corresponding
studs or axes carried by the lid but these means of connection are not so secure
as is desirable added to which the inclined slots are difficult and expensive to
produce.
Now the objects of my invention are to render the cover capable of ready
connection and disconnection with the jug or other vessel and to simplify that part
of, the connecting means carried by the jug.
For this purpose upon the underside of the balance cover in suitable bearings
arranged transversely thereof I mount with capability of sliding a long bolt or
'spindle and connect this sliding bolt or spindle through a transverse slot formed
in the cover with a knob or button located upon the upper side of the cover and
furnished with a covering plate to conceal the slot.
The sliding bolt or spindle is so connected with the knob or button that in one
position of the bolt both ends thereof project an equal distance beyond the cover
whilst in the other position one end is entirely retracted beneath the cover whilst
the other end is correspondingly further projected and this sliding bolt constitutes
that part of the connecting means which is carried by the cover.
The other part of the connecting means carried by the jug or other vessel consists
of two small holes formed therein one upon each side of the mouth thereof near to
the lip or top edge and in true alignment with each other and these holes may either.
be formed previous to firing the jug or other vessel or subsequently by drilling as
may be found most convenient the operation in either case being of a simple and
inexpensive character.
The 'holes in the jug constitute bearings for the ends of the sliding bolt or spindle
and the cover is placed in position by retracting the bolt or spindle tilting the cover
'to one side inserting the doubly projecting end of the bolt or spindle in one hole or
bearing then lowering the cover to a horizontal position and by the aid of the knob
or button shooting the retracted end of the bolt or spindle into the corresponding
hole or bearing a spring or other stop being employed to prevent the accidental
sliding back of the bolt or spindle.

According to a modified arrangement I dispense with the sliding knob or button
and substitute therefor a turn button which gives motion to the sliding bolt or
spindle through a cam or eccentric.
According to a further modification I divide the bolt or spindle transversely
into two parts and give motion to both parts by means of a turn button or
the like.
And in order that the said invention may be more clearly understood and readily
carried into effect I will proceed aided by the accompanying drawings more fully to
describe the same.

page_text: Fig
Tigure 4 is a plan thereof.
Figure 5 is a transverse section taken on the line 3-3 of Figure 6 representing
a modified device for actuating the sliding bolt.
Figure 6 is a plan thereof.
Figure 7 is a transverse section taken on the line 4-4 of Figure 8 representing
a modified form of bolt and
Figure 8 is a plan thereof.
Figure 9 is a transverse section taken on the line 5-5 of Figure 10 representing
a further slight modification and
Figure 10 is a plan thereof.
In the several figures like parts are indicated by similar letters of reference.
Referring to Figures 1-4 a represents the jug and represents the balanced
cover upon the underside of which and transversely thereof is provided a tubular
guide within which is mounted with capability of sliding a long bolt or spindle cl
which is connected through a transverse slot & formed in the cover with a knob
or button located upon the upper side of the cover band furnished with a covering
plate to conceal the slot 6.
C
The sliding bolt or spindle c¹ is so connected with the knob or button c that in
one position of the bolt c¹ that is to say when the knob or button is at one end of the
slot it will occupy a central position with relation to the cover band both ends of
the bolt c will project an equal distance beyond the cover bas represented by the
full lines in the drawings whilst in the other position of the bolt cone end thereof
will be entirely retracted beneath the cover whilst the other end is correspondingly
further projected as represented by the dotted lines in Figure 3 and this sliding
bolt constitutes that part of the connecting means which is carried by the
cover b.
The other part of the connecting means carried by the jug or vessel a consists of
two small holes a¹ formed therein one upon each side of the mouth thereof near to
the lip or top edge and in true alignment with each other and these holes a' may
either be formed previous to firing the jug or other vessel or subsequently by drilling
as may be found most convenient the operation in either case being of a simple and
inexpensive character.
The holes a' in the jug a constitute bearings for the axes formed by the ends of
the sliding bolt or spindle c' and the cover is placed in position by retracting the
bolt or spindle c¹ as represented by the dotted lines in Figure 3 tilting the cover to
one side inserting the doubly projected end of the bolt or spindle c¹ in one hole or
bearing a then restoring the cover to a horizontal position and by the aid of the
knob or button shooting the retracted end of the bolt or spindle into the corre-
sponding hole or bearing a' a spring stop c* being employed as represented in
Figure 3 in order to prevent the accidental sliding back of the bolt or spindle c'.
In the arrangement represented a Figures 5 and 6 the slot in the cover bis
dispensed with and the sliding knob or button is substituted by a milled turn button c
which has fixed thereto a disc located upon the underside of the cover and
provided with an eccentric or cam slot c¹ which engages a stud c¹ carried by the
sliding bolt or spindle c' so that by rotating the turn button the eccentric slot c¹
will act upon the the stud c¹ to traverse the sliding bolt or spindle c' in the manner
herein before described with respect to the previous figures but in this arrangement
the spring stop c* is dispensed with.
In the example given at Figures 7 and 8 the sliding bolt or spindle c¹ is divided
transversely into two parts and each part is furnished with a stud c¹* whilst the
disc is provided with two eccentric slots c' so that by rotating the turn button c
in one direction both parts of the bolt c¹ will be simultaneously retracted beneath
the cover b as shown by the dotted lines in Figure 7 and the cover may be placed in
the mouth of the jug when upon rotating the turn button c in the opposite direction
both parts of the sliding bolt or spindle c¹ will be simultaneously projected as

page_text: shown by the full lines in Figures 7 and 8 when they will enter the holes a¹ of the
jug a and secure the cover in the desired position.
In the example given at Figures 9 and 10 the sliding bolt or spindle c¹ and its
tubular guide & are mounted upon the upper side of the cover but the bolt or
spindle is actuated by means of a sliding knob or button in a similar manner to
that described with respect to Figures 1 to 4 but in this case the bolt c¹ is divided
into two parts e¹ c** that part e¹ being connected with the knob or button e whilst
the part is fixed with the tubular guide .
The knob or button c is connected with the bolt c¹ through a slot which in this
case is formed in the crown of the tubular guide the covering plate c² being
shaped to fit the same a spring * being employed to normally retain the moveable
part in its projected position whilst an additional covering plate ** located upon
the underside of the cover closes a slot 2* in the cover b through which the
spindle of the knob or button c passes.
As a modification of the device lastly hereinbefore described the slot ** in the
cover b and the covering plate c²* may be dispensed with the spindle of the knob or
button c terminating at the moveable part c¹ of the bolt instead of passing through
the cover b.
By the means hereinbe're described I am enabled readily to connect and
disconnect the cover with the jug a or other vessel whilst when the cover b is in
position the projecting ends of the bolt care held securely in the holes a' in the
jug or vessel and it is thus rendered impossible for the cover b to accidentally
become disconnected therefrom.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
1. In a balanced cover for a jug or other vessel the combination of a long sliding
bolt or bolts forming axes for the cover a knob arranged centrally thereof for
actuating the same and a covering plate for concealing the connection of the
knob with the bolt substantially as herein shown and described and for the purpose
stated.
2. In a balanced cover for a jug or other vessel the combination of a single
sliding bolt normally projecting beyond each side of and forming axes for the cover
suitable bearings for the bolt and means for traversing the bolt and retracting one
end beneath the cover substantially as herein shown and described and for the
purpose stated.
3. In a balanced cover for a jug or the like the combination of a sliding bolt or
bolts normally projecting beyond the cover and a cam or eccentric for retracting
the bolt or bolts substantially as herein shown and described and for the purpose
stated.
