IMPROVEMENTS IN MACHINERY OR APPARATUS FOR CONCRETE BUILDING
Year: 1884

page_text: COMPLETE SPECIFICATION,
We WILLIAM JOHN EARLE HENLEY and EDWARD JOHN EARLE HENLEY both
of Anerley in the County of Surrey Builders do hereby declare the nature of our
said Invention for IMPROVEMENTS IN MACHINERY OR APPARATUS FOR CONCRETE
BUILDING" and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :—
The object of our improvements is to afford increased facilities for erecting
buildings, or portions of buildings, of concrete, by means of a novel arrangement of
portable apparatus for moulding, forming, shaping and coring the various portions
of the building; the apparatus being retained in position only so long as is
necessary for the structural work to set and harden after which the apparatus is
removed and is available for other analogous operations.
Our said Invention is not only applicable to concrete building but also in
combination with ordinary masonry and brickwork, to terra cotta, compo, cement,
and analogous building materials; and to the construction of plinths, skirtings
ribs, string courses, copings, panels and cornices, and effects a great saving in
labour and in working.
In order that our said Invention may be understood reference is hereby made
to the accompanying Drawings in which similar letters of reference indicate
corresponding parts in the several figures.
Figure 1 represents our Invention in elevation. se shew the boards in position
for buildingz shew the method of lowering and lengthening the boards in the
independent carriage pieces d d. b b are the wall guages.
Fig. 2 and 3 represent details shewing the method of connecting the working
parts together.
Fig. 4 is a section of a wall in process of erection, with the plinth and skirting
formed.
Fig. 5 is a section of a wall shewing plinth's panels and cappings formed.
Fig. 6 shews other sections such as string couses in process of formation.
Fig. 7 is a ground plan shewing the mode of laying down the apparatus.
Fig. 8 is a section and Fig. 9 an elevation of my improved collapsible core. On
moving the lever y towards the core is reduced in diameter and rendered capable
of being easily removed-The rod w extends from end to end in order to actuate

page_text: 00
the whole of the core simultaneously. When the lever is moved towards it is
pinned back in that position.
In carrying out our Invention we employ a revolving and adjustable apparatus
which may be constructed of wood or metal, or a combination of wood and metal.
We form the uprights a with flanges of metal of any suitable length and
thickness, fastened or riveted together, providing suitable spaces for the wall
guages and having round or slotted holes placed therein at suitable distances for
the purpose of receiving the bolts or pins and the wall guages b.-We form the
wall guages b of flat or square metal having round holes or slots to receive the
bolts or pins c which pass through one side of the upright; then through the wall
guage and through the other side of the upright, thus bolting or pinning the three
straps of metal together, the bolt or pin ends to receive and fasten the revolving
and adjustable metal carriage pieces or clasp end plates thereto, viz., on each side of
the uprights; the carriage pieces are independent of the panels or boards, the top
and bottom ends of the uprights are slightly rounded to allow them to revolve on
the top bolts or pins without being unfastened or disconnected from the wall
guage or from the rovolving carriage pieces or clasp ends. The angle uprights are
formed in a similar manner with the flanges of metal before described, but are
screwed or fastened to wood so as to allow the wall guages to stand at right
angles.
The uprights may also be formed of wood and cased on each side with metal,
and shoes are placed on the top and bottom ends and slotted pieces of metal are
placed in the centre to receive the wall guages as shewn in Fig. 3 and suitable
fastenings are also attached to connect the carriage pieces or clasp ends to the
uprights or to connect the wall guages to the uprights.
The extending adjustable and revolving carriage pieces or clasp end plates d are
formed of metal in one or more parts, having reversible slots or holes on the ends
to revolve and to fasten on the ends of the bolts or pins each side as placed
through the wall guage and through the uprights on the said carriage pieces or
clasp end plates we form a series of holes or slots on the two sides in order to
adjust and to regulate the revolving panels or boards e to the various forms of
construction as may be required, and by this arrangement the panels or boards cau
be easily raised, lowered or lengthened out or placed in the inside or attached on
either side, or to the various forms required for construction with the single
boards. The carriage pieces or clasp end plates are securely held by means of bolts
or pins passing through them as required, and without unfastening or "disconnecting
the carriage pieces or clasp end plates from the uprights. By this arrangement,
plinths skirtings, string courses, panels cappings and cornices may be readily
formed in concrete as the work proceeds.
We form the revolving panels or boards e of wood or metal, but preferably of
wood with square edges with boards making one panel and they are sometimes
formed with single boards which we use in preference as shewn in Fig. 1. On the
ends of the panels or boards we place metal plates. bands or straps having a series
of holes or slots, similar to those formed on the sides of the carriage pieces or
clasp end plates, to receive the bolts or pins or other suitable fastenings. The
panels or boards work between or on either side of the carriage pieces or clasp end
plates and are securely held at the various positions by means of bolts or pins
passing through one side then through the holes in the panel or board and out
through the other side of the carriage pieces, or clasp end plates. The carriage
piece or clasp end may be formed to work on one side of the plate only, of metal-
Angles and projection pieces are formed in a similar manner.
We form the adjustable guides ƒ of pieces of square or flat metal, with holes
formed at each end, and various holes are formed throughout their length inclining
to the centre, to receive the bolts, and to fasten the small hanging pieces and
which may be adjusted as required to keep the panels or boards in the necessary
ningitione

page_text: These adjustable guides are fastened together with bolts, and are placed around
on the outside faces, and over and under the top and bottom edges of the reversible
panels or boards; the hanging pieces are also riveted or bolted to the same and
hang down at the sides when not in use, but when in use they are raised.
We form the flue cores g of metal with metal bands having the joints lapping
over each other, and the inside laps turned as shewn in Figs. 8 and 9, holes being
formed therein to receive pins to grip over the lever action; -These bands are
placed at the top and at the bottom of the core and are covered with thin metal
and made to any suitable size or length-On the outside lap or joint we place a
strap of metal the length of the core with the ends turned in, and over the top and
bottom ends of the core the turned ends of the metal strap have a hole formed
therein to receive and fasten the pivots, which we attach to a rod of metal and
which we place in the inside of the core.
It will be seen on reference to Fig. 8 that the action of this lever on being moved
from y to a reduces the diameter of the core, and by dropping a pin in the small
hole formed on one side of the handle the core is kept contracted, so as to allow of
its being readily withdrawn :-On the bar at the bottom of the core we fix a
similar arrangement but the handle is there unnecessary as the rod w communicates
the necessary motion thereto.
Having now particularly described and ascertained the nature of our said said
Invention and in what manner the same is to be performed we declare that what
we claim is:-
1. The manufacture and use of reversible uprights as and for the purposes
described and shewn on the Drawings, Figs. 1 to 7.
2. The manufacture and use of independent revolving adjustable carriage pieces
or clasp end plates as and for the purposes described and shewn on the Drawings
Figs. 1 to 7.
3. The manufacture and use of reversible panels or boards as and for the purposes
described and shewn on the Drawings, Figs. 1 to 7.
4. The manufacture and use of central guides as and for the purposes described
and shewn on the Drawings Figs. 1 to 7.
5. The manufacture and use of flue cores as and for the purposes described and

6. The manufacture and use of the several and respective parts, together forming
