Complete Accepted, 23rd Sept., 1887
I JOSEPH TALL of Belvoir Road, Lordship Lane, Dulwich, Surrey, Concrete
Buildings Constructor, do hereby declare the nature of my said invention to be as
follows:-
:-
The object of this invention is certain detail appliances to be used in the construction
of concrete walls in order to facilitate an easier connection and disconnection of the
stages, frames or panels.
For the purpose of my present invention which is based upon prior patents dated
23rd March 1865, 21st August 1868, 30th August 1877; 16th November 1880, I
make and use a long hooked spike, the upper end of which is at right angles and has
a depending leg, between which and the shank or main stem, a crutch is arranged for
keying the panels together by means of a tapered rotatable bolt, which by a half round
turn in one direction secures the panels and a half round turn in the reverse direction
allows them to be detached.
Further, for the corners or other parts I make and use bolts which have a head or
shoulder on one side of the head only, which can by a turning operation, after passing
through a hole, bear against an inclined surface of the backing plate to be nipped
tightly.
The opposite ends of the bolts are threaded and have nuts, the threads being right
or left handed according to the side or end of the panel occupied by them.

Construction.
I, JOSEPH TALL, of Belvoir Road, Lordship Lane, Dulwich, Surrey, Concrete
Buildings Constructor 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:-
The object of this invention is certain detail appliances to be used in the construction
of concrete walls in order to facilitate an easier connection and disconnection of the
stages, frames, or panels.
For the purpose of my present invention which is based upon prior patents granted
to me and dated 23 March 1865, 21 August 1868, 30 August 1877, and 16 November
1880, I make and use a long hooked spike A see Figures 1, 2, and 3, the upper end B
of which is at a right angle and has a depending leg Cover or between which and the
shank or main stem A a crutch D is arranged for keeping the panels E, E, together
by means of a tapered rotatable bolt F, which by a half turn round in one direction
secures the panels E, E, and a half turn round in the reverse direction allows the
bolt F to be withdrawn for the panels to be detached.
Further, for the corners or other parts I make and use bolts G G, each of which has
a head or shoulder H on one side of the head only see Figures 4 and 5, which
bolts can by a turning operation after passing through a hole or a notch I bear
against an inclined surface of the front plate J, see Figures 6 and 7, to be nipped
tightly.
The opposite ends of the bolts G G are threaded and have nuts K embedded, the
threads of the bolts G G being right and left handed according to the side or end of
the panel E occupied by them, said bolts G, G, being in the corner pieces L.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :-
1. The detail appliances herein before set forth and substantially as represented in
the annexed drawings for the purpose explained.
2. The spike A, B, C, arranged as and for the purpose described.
3. The tapered bolt Fas and for the purpose described.
4. The plate J in combination with the single headed bolt G as and for the purpose
described.
