Improvements in Building Blocks for Arches and the like.
1, FRANCIS WILLIAM HOLLOWAY of Paddock Hall Road Haywards Heath
Sussex Building Surveyor do hereby declare the nature of this invention to be as
follows:-
:-
To form out of stone, concrete, cement, burnt earth or any other available and
suitable material: blocks of such uniform shapes of their respective class, as
shall by the aid of key blocks, comprise when set in mortar, cement, fire .clay
or other adhesive material, arches without any cutting, each block or voussoir
being a repetition in shape, formed respectively with upright or sloping joint
beds, with ledge or bearing, so that each will fit the adjoining block, thereby
admitting and facilitating convenient hacking, crowding, or burning and formed
with or without, furrows frogs or other indents, being capable of adjustment to
any depth of arch or width of opening; and what I claim as novel besides the form
of shoulders to take bearing, and to reduce thrust, is the similarity in form and
system of each block respectively and the facility thereby given for manufacturing
or setting and adaptation to any width of opening; the accompanying elevations
being drawn, for exemplification, to a scale of 1 inch to a foot, the width of each
voussoir, or its depth not being material; with side sketches in illustration of the
system.
A. A. K being for arches, four courses of brickwork in height, with upright
beds, with or without the cross joints indicated by dotted lines.
B. B. K the same for arches three courses high.
C. C. K the same for arches two courses high.
D. D. K. the same for arches two courses of brickwork in height, with sloping
beds.
E. the same for arch or part of full height one and a half courses high, with
either upright or sloping beds.
F. FK for arch three courses high, with sloping beds, with or without cross
joints as indicated by dotted lines. Or, for any of them in combination for
arches of any required depth.

COMPLETE SPECIFICATION.
Improvements in Building Blocks for Arches and the like.
I, FRANCIS WILLIAM HOLLOWAY of Paddock Hall Road, Haywards Heath,
Sussex Building Surveyor do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
The object of my invention is to form from stone, concrete, cement, burnt
earth or any other available and suitable materials, blocks of such uniform shapes
of their respective class as shall, by the aid of key blocks, comprise, when set
in imortar, cement, fire-clay or other adhesive materials arches without any
cutting, each block or voussoir being a repetition in shape formed respectively
with upright or sloping joint-beds, with ledge or bearing so that each will fit
the adjoining block, thereby admitting and facilitating convenient hacking,
crowding or burning and formed with or without furrows, frogs or other indents,
being capable of adjustment to any depth of arch or width of opening.

page_text: In the accompanying drawings left with the Provisional Specification I have
shown various forms of blocks and key blocks made according to my invention
with side sketches of building work illustrating the applicability of each form
respectively.
A, A K are a block and key block suitable for arches, four courses of brick-
work in height, with upright joint beds, with or without the cross joints indicated
by dotted lines.
B, BK are a block and key block of the same kind as A AK but intended
for arches three courses of brickwork in height.
C, CK are a block and key block of the same kind as A AK but intended
for arches two courses of brickwork in height.
D, DK are a block and key block of a similar kind to A AK but having
sloping joint-beds.
E is a block similar to the block D but intended for arches one and a half
course of brickwork in height.
F, FK are a block and key block of the same kind as A. A K but having
sloping joint-beds.
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
1. Blocks or voussoirs for use in building arches or horizontally bridging
openings in brickwork, being moulded or formed with steps and vertical or
sloping joint-beds, the depth of such blocks or voussoirs being made to corre-
spond with any required number of courses of brickwork substantially as described.
2. In blocks or voussoirs, such as those described in the above first claiming
.clause, the formation of furrows, frogs or other indents in the joint-beds, by
which to bind the work in a manner more effectually to resist lateral pressure.
Dated this 5th day of April 1892.
