B SHAP
Year: 1885

page_text: FRANCIS BOYES 5 Graham Street East Hartlepool County of Durham I do hereby
declare the nature of my invention for THE MAKING OF COMON BRICKS OF ALL
SHAPES &C to be as follows:-
The construction of the die is a wood casing lined out with narrow Strips of
Brass or Steel-iron overlaping each other and feed from the top of die passing
through the wood casing and coming underneath stell strips and I propose to
fastening the whole together with a staple bolt and cross straps passing through
the ends of die.
And to my so aranging the distribution of Lubricant to assist the clay in
leaving the mill. Likewise each die as fixed under neath with iron dish for the
saving of oil wich can be used over again.
This invention relates to improvemts in moulds or dies as used in connection
with Brickmaking machines which latter may be of the ordinary class arrainged
either vertically or horizontally, and may be steam driven or otherwise
The
moulds as per my invention may be arranged and adapted for either plain or fancy
bricks and are constructed as follows Whereas. hitherto moulds of this class that
is to say moulds or dies so arranged with diagonally placed strips of suitable
witdh and overlaping each other (the said strips bieng constructed of tin) and the
front of the mould or die of brass In mine the several strips are constructed of
brass or other suitable metal and are reversable and the several strips are attached
to casing of die (which latter may be of wood or suitable) with screws Instead of
the outer casing bieng bolted together with the screwed bolts passing through the
said casing I propose to employ straps for the purpose The said bieng let into the
wood flush with that side of casing next to the machine It will be understood
that the class of mould or die described is of the Lubricating typo and what
I claim as my invention is increased durability and greater economy in lubricants
which latter may be gas oil water or steam &c Increased duribility is attained by
ny employing brass or other mettalac reversable strips instead of ordinary tin
Greater economy of lubricats is secured by my so arranging the distribution of

page_text: same that it shall be effective and this is attained in manner following Whereas in
the ordinary casing there is a centre feed hole at top corosponding feed holes bored
in the sides and bottom or groves leading therefrom to inside of casing which is
lined out with fustian all round to secure same.
I propose to provide casing with two feed holes one at either side as shewn and
pass down and along centre of casing and through small feed holes and coming up
close to brass strips or other mettalic linnings or plates of same along the bottom
The linnings bieng so closley fitted as with the aid of tap at cistern to properly
regulate and and distribute the flow of the lubricant The brass strips refered to
I propose to make of a great degree of hardness.

page_text: FRANCIS BOYES, 5 Graham Street Hartlepool County of Durham Joiner and
Builder, do hereby declare the nature of my invention for IMPROVEMENTS
LUBRICATING BRICK DIES and in what manner the same is to be performed, tỏ
be particularly described and ascertained in and by the following statement :-
This invention relates to improvements in moulds or dies, as used in connection
with brick making machinery which latter may be of the ordinary class arranged
either vertically or horizontaly and may be steam driven or other wise.
The moulds as per my invention may be arranged and adapted for either plain
or fancy bricks and are constructed as follows Whereas hitherto moulds of this
class that is to say moulds or dies so arranged with diagonally placed strips of
suitable witdh and overlaping each other (the said strips bieng constructed of tin)
and the front of the mould or die of brass, In mine the several strips are con-
structed of brass or steel or other suitable metal and are reversable and the several
strips are attached to casing of die) which latter may be of wood or other suitablo
materail) with screws.
Instead of outer casing bieng bolted together with screwed bolts passing through
the said casing.
I propose to employ straps for the purpose, the said strap bieng let into the wood
flush with that side of casing next to the machine.
It will be understood that the class of moulds or die discribed is of the Lubricating
type and what I claim as my invention is increased durability and greater
economy in lubricants which latter may be gas oil water or steam Increased
duribilaty is attained by my employing brass or other mettalic reversable strips
instead of ordinary tin.
Greater economy of lubricants is secured by my so arranging the distribution of
same that it shall be more effective and this is attaned in manner following
Wheras in the ordinary casing there is a centre feed hole at top and corresponding
feed hole bored in the side and bottom with a series of groves leading therefrom to
inside of casing which is lined out with fustian all round to receive same.
I propose to provide casing with two two feed holes one at either side as shewn
and pass down and along centre of casing and through small feed holes as shewn
coming up close to brass or mettalic strips or liners or plates of same along botton
the linnings bieng so closely fitted as with the aid of tap at cisteran to properly
regulate and distribute the How of the Lubricant the brass strips referd to I propose
to make of a great degree of hardness.
In my provissional specification I claim the use or employment of brass or other
metallic strips in substiation of the tin strips and fustian linnings as prevously
used for the purpose my experiance has led me to adopt rolled steel strips to be
used for the purpose and these are fitted throughout the last or terminating layer
of strips only bieng of brass.
Another important feature is the employment of corner pieces for the production
of bricks of different sections as for instance chamford-Bullnosed O. G. and other

page_text: formas This arrangement is shewn on the acompanying drawing and marked x
The said corner piece or pieces is or are detachable and when in use are screwed by
means of screw or screws In cases where one only is enployed it is prefered to
fit it in one or other of top corner of die thus securing more perfect lubrication
than would be the case if fitted on either of the bottom corners.
Refering to the drawing a aa a is the casing bbbb are the steel strips or
liners and which it will be understood are carried round the four sides 6¹ bieng
brass strip or liner cco are the passages of the lubricants da drainer for the
reciption of the spare lubricant e e are the straps refered for binding and securing
the mould or die together.
Having now particlaury discribed and acertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1st The employment of the combination of steel with brass liners or strips as
per manner discribed and with reference to the acompanying drawings.
2nd Improved mode of lubrication as discribed.
3rd The enployment of corner pieces of various sections for the purposes set
forth.
