An Improvement in the Manufacture of Building Blocks or Bricks
and the like.
WALTER WRIGHT, 48, Chesterton Road, North Kensington, Gentleman, do
hereby declare the nature of this invention to be as follows:-
My invention relates to an improvement in the manufacture of concrete, terra
cotta, or other clay or cement, or composition blocks, or bricks, or any block,
or brick, of any other substance, for facilitating the use and handling of same.
The improvement consists of a handle or sunken or raised bar, or ring, or eye,
or a cavity, having a projecting part in it, to clutch with the hand, or with clips,
or tongs, or hook, for the purpose of lifting, and handling the blocks, or bricks.
The advantage of these handles, holders, clutches, or lifts is that blocks, or bricks,
made of any materials, ornamental, or otherwise and of any size, may be readily
handled laid or used. My invention consists of adding to any block, or brick,
the handle, clutch, grip or lifting arrangement.
Dated this 10th day of February 1898.

An Improvement in the Manufacture of Building Blocks or Bricks
and the like.
I, WALTER WRIGHT, of 48, Chesterton Road, North Kensington, London,
Gentleman, 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 the manufacture of concrete terra
cotta and other clay or cement or composition blocks, bricks, or slabs, or blocks,
bricks or slabs of any other suitable substance.
My improvements consist in forming or providing blocks or bricks with means
hereinafter described for handling same and in this my invention I prefer to
make the bricks of a larger size than the bricks hitherto used for building.
I do not confine myself to any particular method of making my blocks easy
to handle but I may use a metal or other bar in a recess of the block or a metal
or ring in the recess of the block or I may make a frog similar to the frog of a
brick and undercut the said frog so as to form a grip for the hand or so as to
form two grips, one for each hand. A further method is to make two frogs or
TT 977

page_text: recesses in a block and undercut them so as to enable the block, if large, to be
carried by tongs or other gripping arrangements. These blocks, for the purpose
of lifting may if required be mainly skeleton blocks and may be filled in with
cement, concrete or other suitable material which forms a binding material
between the blocks. The blocks may further be formed with tongues and
grooves to fit into each other if desired. Among the advantages of this my
invention are that building blocks may be made much larger than ordinary bricks
and may be handled as readily thus saving the labour of handling and selecting
the right side of bricks in building. Further I reduce the cost of the mortar
between the joints of bricks and the cost of laying same and in cottage property
the blocks require no plastering inside. As these blocks require no facing with
mortar a building may be erected from the inside without any scaffolding outside.
In order that my invention may be readily understood reference is made to the
accompanying drawing in which various forms of my improved blocks or slabs
are illustrated.
One form of my blocks is shown in side elevation and plan view respectively
in Figs. 1 and 2 the upper part of Fig. 1 being shown in section on the line x y
Fig. 2. In this form the block A is "stepped" about as shown and is formed
with ribs a and corresponding recesses a¹ so that in building said blocks up the
ribs of one block will enter the recesses of the adjacent block and thus more
or less lock them together. The upper part of said block is formed with a recess
or deep frog b across which I form a handle c of suitable shape and of the same
material preferably of which the block is made. I also leave frogs or grooves
into which the cement, mortar, or other material used for joining the blocks, is
placed.
Figs. 3 and 4 show in sectional side elevation and plan view respectively,
another form of block, the section being on line y Fig. 4. In these figures a
block A is shown which is too wide to be gripped by one hand excepting by
the application of my invention, and to enable said block to be grasped and lifted
by one hand I form said block with a recess e so as to reduce the width of the
block at about its centre on the top surface and I further preferably undercut
said top surface so as to leave a projecting part f, so that the said block may
be firmly grasped and lifted by one hand, the fingers of the hand being prefer-
ably placed along the sloping side of said part 7. Fig. 5 shows in sectional side
elevation a block similar to that shown in Figs. 3 and 4, but the width of this
block is greater than that shown in Figs. 3 and 4 and on this account is formed
with a recess e and undercut portion at each side so as to leave a part f at each
side of the block.
Fig. 6 shows in sectional elevation a block A formed with a handle e similar
to that shown in Figs. 1 and 2 but in this block, the lower part is formed with
an aperture thus leaving projecting ribs or the like so that a hook or other
device may be put through the aperture and engaged with the ribs to enable
said block to be slung and hoisted. In this block A the handle c is strengthened
by a metal strip c¹ which is embedded at its ends in the material of which the
block is made. Said strip which is applicable to all forms of my improved
blocks not only strengthens the handle, but, also forms a support to the handle
whilst drying when the block has been moulded or otherwise formed.
Fig. 7 shows in section a part of a block A formed with a deep frog or recess b
and is provided with a metal handle j shaped about as shown and having its ends
embedded in the body of the block.
Fig. 8 shows in section a part of a block A formed with a deep frog or recess
which is undercut as at 61 so as to leave projecting handle parts h by means of which
the block A may be readily lifted.
Among the advantages appertaining to this my invention are that blocks or
slabs used for building may be made much larger than they are at present and
yet handled with equal or even greater facility. Further, as the blocks may be
made of a size equal to several bricks hitherto employed thus reducing very

considerably the time required to build a wall or other structure. Very con-
siderably less mortar, cement or other material is required between the joints as
my improved blocks may be comparatively very large and further, as no "facing"
is required a building may be erected from the inside thus obviating the necessity
of scaffolding and in many buildings, especially of the cheaper kind such as
cottages, plastering on the inside may be entirely dispensed with as the blocks
themselves when properly moulded and laid, form a sufficiently smooth surface
to receive the wall paper. If desired my improved blocks or the like may be
mainly skeleton blocks so as to be adapted to be filled in with cement, concrete
or other suitable material to bind said blocks together.
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:-
-
Making building blocks, bricks or slabs so that they may be readily handled
for the purposes and in the manner set forth.
