PROVISIONAL SPECIFICATION.
An Improved Mode of Preparing, Fitting, and Laying Blocks, for
Floors, Walls, or Ceilings, of Wood or other material.
I, HENRY HUMPHRIES CRIBB, of the firm of Marsh, Jones, & Cribb, of Boar
Lane, Leeds, in the County of York, Cabinet Makers, do hereby declare the nature
of this invention to be as follows:-
This invention which bears relationship, as to its system of interlocking, to a
former one of mine, for which provisional protection was granted, under No. 21,004,
Dec. 2nd 1891, refers to a modification in my method of treating the abutting edges
of the blocks which are to be joined, and has for its object the interlocking of the
blocks one into the other, in such a way that they hold one another in position, and
in true plane with one another; and, when desired, also lock themselves in every
direction into cement, or other similar substance, such as may be squeezed into
grooves prepared for its reception on the innermost sides of the blocks.
I accomplish my object as follows, taking a rectangular block as an example:-
I cut, cast, or otherwise prepare, projections on two adjacent sides of each block,
and, further, sink corresponding channels on the other sides, opposite to those with
the said projections. These projections and corresponding channels are prepared
on all blocks, at a relative distance below the outer surface which has afterwards to.
be brought into true line.
When blocks thus prepared are laid, it follows that the projections on one block,
may be, and are, fitted into the recessed portions in the neighbouring blocks, and
so on; each block interlocking with those with which it is laid in contact.
Some shapes of blocks, for example, triangular, will not lend themselves to the
arrangement in which two sides interlock into two other sides; in these and in
other cases, my system may be modified, by making some pieces with nothing but
projections, and others with nothing but recesses, on their sides.
The inner portions of all blocks, may be recessed on every side near their inner-
most surface, to enable them to surround and fasten themselves to cement, or the
like, squeezed therein, for the purpose of fixing the blocks to their backing.
Where no cement is used, certain of the blocks would require pinning to the
backing, here and there, in any suitable way.
Dated this 5th day of January 1892.

COMPLETE SPECIFICATION.
An Improved Mode of Preparing, Fitting, and Laying Blocks, for
Floors, Walls, or Ceilings; of Wood or other material.
I, HENRY HUMPHRIES CRIBB, of the firm of Marsh, Jones, & Cribb, of Boar
Lane, Leeds, in the County of York, Cabinet Makers, 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:-
This invention, which bears relationship as to its system of interlocking to a
former one of mine, viz. that described in Specification No. 21,004, Dec. 2nd 1891
refers to a modification in my method of treating the abutting edges of the blocks
which are to be joined; and has for its object the interlocking of the blocks one
into the other, in such a way that they hold one another in position, and in true

page_text: plane with one another; and, when desired, also lock themselves in every direction
into cement, or other similar substance, such as may be squeezed in process of
laying into grooves prepared for its reception on the innermost sides of the
blocks.
In order to fully explain my mode of proceedure I have annexed a drawing on
which
Figs. 1, 2, 3 and 5 are plans of groups of different shapes of blocks ready for
laying, but separated' from one another for the sake of showing their respective
formations. Fig. 4 is a vertical section on the line X Y in Fig: 3. Figs. 6, 7,
and 8 are enlarged vertical sections showing joints between neighbouring blocks.
The same letters refer to the sanie parts in all the figures.
I accomplish my object as follows, taking a rectangular block as an example,
such as shown in Figs. 1 and 2 :-I cut, cast, or otherwise, prepare, projections a. a.
on two adjacent sides of each block, A, and, further, sink corresponding channels b, b,
on the other sides, opposite to those with the said projections. These projections
and corresponding channels are prepared on all blocks, at a relative distance below
the outer surface B which has afterwards to be brought into true line-see
Fig. 6.
When blocks thus prepared are laid, it follows that the projections a. a. on one
block, may be, and are, fitted into the recessed portions b, b, in the neighbouring
blocks, and so on; each block interlocking with those with which it is laid in
contact..
When blocks are oblong, as in Fig. 1, two classes have to be made ;-one with
the projections on a given end and on the right hand side, as at A', Fig. 1, and the
other with the projections on the same end but on the left hand side, as shown
at A Fig. 1.
Small blocks, such as those in Fig. 3, may either be treated in the same manner
as the larger ones, as at A' Fig. 3, or they may be held by projections as at A¹ in
Fig. 3, and, in section, in Fig. 4. In the latter case the projections or recesses, as
the case may be, are run round all sides of the blocks, and the corners of the larger
ones are arranged to suit.
Some shapes of blocks, for example, triangular, will not lend themselves to the
arrangement in which two sides interlock into two other sides; in these and in
other cases, my system may be modified, by making some pieces with nothing but
projections, and others with nothing but recesses, on their sides, and then using
them alternately. This is clearly shown in Fig. 5, the block A having projections
on all three sides (with their points cut away somewhat to clear one another)
whilst A has nothing but recesses.
The section of joint shown in Fig. 6 is so arranged that in addition to its inter-
locking, block with block, it allows waves of cement to be swept-by a cornerwise
advance of the block into position-into the two spaces, C, prepared for its
reception; one such space being at the end and the other at the side of the block.
The section in Fig. 7 shows the joints to be made by the use of ordinary pro-
jections and recesses. In this example no space is shown for receiving cement.
Fig. 8, which is a section of a waved tongue and groove similar to Fig. 6, shows
how nails or spikes may be used in fixing the blocks, a suitable substance being
arranged for receiving the point of the spike.
As already stated the inner portions of all blocks, may be recessed on every side
near their innermost surface, to enable them to surround and fasten themselves to
cement, or the like, squeeged therein, for the purpose of fixing the blocks to their
backing as shown in Fig. 6. In this way when a given block has had its surrounding
blocks laid it will be imbedded on all four sides, and this mode of fixing, when
practicable, is the one to which I give preference.
When no cement is used certain of the blocks would require pinning to the
backing, here and' there, in any suitable way, as already referred to in describing
Fig. 8.
*Blocks must, of course he understood to auchmoen tilos and the like a

page_text: The drawing must be taken as showing examples only, as ennumerable variations
may be arranged without departing from the essential features of the invention.
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) The improved mode of preparing, fitting, and laying blocks for floors, walls,
or ceilings, substantially as described herein and shown on the drawing.
(2) The use of blocks having projections on two adjacent sides, and recesses on
those opposite, substantially as described herein and shown in Figs. 1 and 2 with
the object and for the purpose set forth.
(3) The use of blocks having projections on several adjacent sides, with recesses
on those opposite, substantially as described herein and shown in Fig. 3, with the
object and for the purpose set forth.
(4) The use of oblong blocks, having projections and recesses as set out in
Claim 2, made and arranged in right and left hand fashion for laying in or after
the manner shown in Fig. 1, with the object and for the purpose set forth.
(5) The mode of arranging and laying interlocking blocks-having joints of the
class described herein-substantially as shown in Figs. 3, 4 and 5, with the object
and for the purpose described.
(6) The waved sectional form of projections and recesses for the class of blocks
under consideration, substantially as shown in Fig. 6, whether the inner sides are
made to embrace layers of cement (or its equivalent) or not.
(7) The hereindescribed blocks whether the projections and recesses be of a
special character, or of the ordinary type as in Fig. 7.
(8) The form of block and spike and manner of fixing substantially as described
herein and shown in Fig. 8 with the object and for the purpose set forth.
Dated this 4th day of October 1892.
