IMPROVEMENTS IN COVERS OR HACK-CAPS FOR COVERING BRICKS IN THE FIELD
Year: 1884

page_text: I WILLIAM SQUIRES. CODNER of 83 Upper Thames Street in the city of London
do hereby declare the nature of my said invention for "IMPROVEMENTS IN COVERS
OR HACK-CAPS FOR COVERING BRICKS IN THE FIELD to be as follows:-
This invention relates to certain improvements in covers or hack-caps for covering
bricks in the field.
The ordinary covers are made of wood with cross pieces of flat board or splines
standing across or longitudinally of the space between the pent-house like covering
and these cross pieces rest upon the bricks leaving air way under the covers at the
same time that the bricks are preserved from rain or moisture. Covers or hack-
caps for like purpose have also been made of arched sheets of metal corrugated or
not but these have been somewhat heavy and damaging to the edges and so forth
of the soft bricks.
According to this invention I. make metal covers or hack caps for bricks much
lighter and stronger and conveniently made for their support upon the soft bricks.
I proceed as follows:-Either curved sheets of light rolled iron corrugated or not
or sheets bent in a pent-house form are employed and cross pieces of sheet iron are
employed standing across the open way or space under the covering sheets and
bolted or rivetted at their ends to the said covering sheets. These cross pieces are
made as follows:-Strips of metal are taken and the longitudinal edges are bent
up at each side at about right angles thus giving rigidity to the cross pieces and
these pieces are rivetted or bolted in position as aforesaid under the covering sheets
so as to present the flat side of the so formed cross-pieces to the top surfaces of
the bricks as a flat bearing surface.
The outer extremities of the turned up edges of the cross pieces are turned over,
outwards (dogs eared) to provide convenient lugs for the bolting or rivetting. The
cross pieces may in some cases be tied together for additional strength.
By these rigid supporting cross-pieces lighter sheet can be employed yet greater
strength is given to the covers or hack-caps produced, together with the requisite
bearing surface which will prevent damage to bricks.
Handles are provided for lifting and so forth.

page_text: I WILLIAM SQUIRES CODNER Iron merchant of 83 Upper Thames Street in the
city of London do hereby declare the nature of my invention for "IMPROVEMENTS
IN COVERS OR HACK CAPS FOR COVERING BRICKS IN THE FIELD" and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention relates to certain improvements in covers or hack caps for covering
bricks in the field.
The ordinary covers are made of wood with cross pieces of flat board or splines
standing across or longitudinally of the space between the pent.house like covering,
and these cross pieces rest upon the bricks, leaving air way under the covers at the
same time that the bricks aro preserved from rain or moisture.
Covers or hack caps for a like purpose have also been made of arched sheets of
metal, corrugated or not; but such metal coverings as heretofore constructed, havo
been somewhat too heavy and damaging to the edges and form of the soft bricks.
According to this invention, I make metal covers or hack-caps for bricks, much
lighter and stronger and possessing a more convenient bearing surface for their
support upon the soft bricks.
In the construction of such improved covers or hack-caps, either curved sheets of
light rolled iron, corrugated or not, or sheets bent in a pent-house form, are
employed, and cross pieces or stretchers of sheet iron are employed standing across
the open way or space under the covering sheets, and bolted or rivetted at their
ends to the said covering sheets.
In the drawings hereunto annexed Figs 1 and 2 respectively represent the curved
and pent house form of hack-caps constructed according to this invention; and
Figs 3, 3 and 4 are details of the special form of crosspieces or stretchers.
The cross pieces or stretchers above referred to, are made as follows:-
:-
Strips of sheet metal a are taken of any convenient length suited to the span of
the cover, and their longitudinal edges b are bent up at each side at about right
angles as shown in Fig 3. The extremities c of the turned up edges b of the cross
pieces u, are turned over outwards (dogs-eared) at the points indicated by dotted
lines, so forming convenient lugs c¹ as represented in Fig 3*.
The cross pieces a thus constructed, are rivetted or bolted in position under the
covering sheets d, so as to present the flat side of the so formed cross piece or
stretcher to the top surface of the bricks as a flat bearing surface.
A modification of such cross pieces or stretchers is shown in Fig 4 wherein the
strip of metal a is turned or rolled up on either side and "wired" as shown; the
projecting ends of the said enclosed wires e being passed through piercings in
the covering sheets d, and secured thereto by nuts or otherwise.
By these supporting cross-pieces or stretchers great rigidity and firmness is
obtained and lighter sheet metal can be employed whilst greater strength is given
to the covers or hack-caps produced, and the requisite broader bearing surface
which will prevent damage to the bricks is thereby secured.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
The improvements in the manufacture of hack caps or covers of metal with the
light binding stretcher pieces, a with their turned up side b secured to the covers d
suid stretcher pieces also providing a smooth bearing surface for contact with and
support upon the bricks as and for the purpose herein specified.
