Improved Means for Constructing Scaffolding so as to Render the
same Readily Adjustable and Portable, which Invention is also
Applicable for Connecting Bars, Strips, Rods, and the like to each
other without Morticing and Tenoning,
We GEORGE BECK of 8 Pierpoint Street in the City of Worcester Architect and
EDWARD ALBERT HANCOCK of Hazeldine in the same City Chemist do hereby declare
the nature of our said invention to be as follows
Our invention is designed to provide improved means for constructing scaffolding
so as to render the same readily adjustable and portable which invention is also
applicable for connecting bars strips rods and the like to each other without mortising
or tenoning.
In carrying out our invention say as applied to scaffolding we may use vertical
poles advantageously of square wood having holes or slots formed therein at equal
distances apart. These holes or slots serve to regulate the height of each tier or
platform of scaffolding..
Each pole is fitted at one end with a metal socket or shoe, into which another
pole is inserted to increase or lengthen the height of the standards supporting the
superstructure.
Additional poles can be fitted as desired. We provide also (advantageously square)
horizontal putlogs fitted at each end with metal brackets having holes or slots formed
therein to correspond with and fit over the pole holes and to which poles they are
secured by screws advantageously of the thumb variety.
We also arrange horizontal ledgers (advantageously of square section) fitted at
each end with metal brackets, the same as those on the putlogs with the addition of
two or more ears to each bracket and with a swivel plate on the head of the bracket
for use when required for securing returned scaffolding.
We for all holes in our structure to correspond so that all pins or bolts used to
connect the parts of the structure are interchangeable.
To effect a return portion of scaffolding one hole is made in the centre of each
ledger to correspond with and fit the hole in the swivel plate on the head of the
bracket, also other holes are made in the ledgers adapted to fit swivel angle strap
plates, secured by screws or bolts. We arrange an adjustable ladder fitted with
sockets to lengthen it out as required by the height of the scaffolding erected.
The ladder or the sections thereof can be secured to the putlogs' or ledgers with
metal clips with screws or bolts.
A putlog and ledger guard is used at convenient heights as required to any
or every tier to guard workmen from falling off the platform or platforms. of the
scaffolding.
The vertical poles may be strengthened by metal if desired.
The bracket joint before referred to may be used in constructing articles of
furniture or for other woodwork or like frameing, whereby speed in construction
labour and expense is saved. Also the parts are always portable.

Improved Means for Constructing Scaffolding so as to Render the
same Readily Adjustable and Portable, which Invention is also
Applicable for Connecting Bars, Strips, Rods, and thè like to each
other without Morticing or Tenoning.
We GEORGE BECK of Pierpoint Street in the City of Worcester Architect and
EDWARD ALBERT HANCOCK of Hazeldine in the said City Chemist 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 our invention is to provide a method or means of constructing
scaffolding trestles and the like whereby the same may be adapted to a variety of
purposes and may be of any suitable size and shape compatible with rectangular
construction. The different parts are correspondent and interchangeable and may be
stowed away in comparatively small compass and can be readily transported from
place to place whilst the different parts may be without difficulty put together by
unskilled workmen and in a short space of time.
Our method of scaffolding may be self supporting entirely or may partly depend
upon the structure against which it is erected for support thus it is equally applicable
for painting &c. the inside or ceilings of large or small rooms or for use outside in
the erection of buildings and other structures.
Referring to the accompanying three sheets of Drawings-
Figure 1. Sheet 1., is a plan of our scaffolding as in use.for the erection of a
building.
Figure 2 Sheet 2 is a view of one angle of the scaffold as at A, Figure 1 shewing
'brackets supporting ledger and putlog also the swivel strap.
Figure 3 is a view of an intermediate putlog.
Figure 4 is an elevation shewing the jointing of a vertical support (bere shown
horizontally reclining).
Figure 5 Sheet 3 is a view of a ledger with its bracket and swivel plate.
Figure 6 is an elevation of the upright supports or scaffold posts shewing holes for
bolts.
In constructing our scaffolding say in accordance with plan shewn by Figure 1. Sheet 1.
we provide rectangular poles or uprights B in which at regular and corresponding
intervals are holes or slots b. We also provide ledgers Cupon the ends of which are
fixed brackets D of peculiar construction. These brackets are provided with a shoe E
on the upper portion or arm to receive the ledger and in the lower or downward
arm G with a side flange F to partially embrace the post or upright in the said
downward arm G and its side flange F are holes 6' to correspond with holes b in the
uprights or supports and it will be seen that according to the shape of the scaffold
either the downward arm G or side flange F'may be bolted to the supports and the ledger
thus turned in either direction and this arrangement is found necessary in returning
an angle. The putlogs H shown in Figure 2 are provided with brackets I also having
holes 6 to correspond with holes in uprights.
Thus say that four posts or uprights B are held or supported temporarily. Two
ledgers CC Figures 1 and 2 are held one against each pair of uprights and bolts or
the like provided for the purpose are passed through the holes 6' in the side flange F
and through the holes 6 in the uprights or ports corresponding thereto. The put-
logs H H Figs. 1 and 2 are then placed against the uprights and at right angles
to the ledgers the holes 6 in the downward arm of the bracket I coming opposite
the holes in the upright post and holes in flange F of ledger C and the bolts already
therein. The bolts are then driven through and secured by nut or other device
as at c Fig. 2.
On the ledger Cand clear of the bracket shoe and on the underside are pivotted
at K two angle straps L L' which when either or both are not required may lie
under said ledger-one of these is now swivelled round and rests under the putlog H

page_text: at the end of each angle strap is a hole or slot and through this and a hole provided
on the putlog is driven a bolt or key. An intermediate putlog is provided as shewn
in Fig. 3 sheet 2 having on one end a fixed clip or saddle M' to ride on the ledger C
and at the other end a swivelling clip or saddle M* pivotted at M³ and capable of
being turned free of the end of the putlog as shown by dotted lines so that the
end thereof may be inserted in a wall when the scaffolding is not self supporting.
The ledgers C are perforated with holes vertically and at regular intervals to
receive the bolts securing the angle straps of other ledgers which may be secured
thereto and opposite any such holes without the necessity of using an upright by
means of a swivelling cap or shoe N Fig. 5 pivotted at N' and which when required
for this purpose is turned on its pivot until it assumes the position shewn by dotted
lines at N'.
The uprights or posts are cut out of suitable lengths and are jointed so as to carry
up the structure to any desirable height as shewn in Fig. 4 sheet 2. The said joints
being preferably metal sockets secured on one end of the lowermost support into
which is passed the foot of the next length of upright which stands therein."
Planks boards or other platform may be arranged on the putlogs and ledgers in the
usual way and intermediate ledgers may be attached to the uprights to form guard
rails ladders jointed in a similar manner to the uprights and provided with clips to
attach them to the ledgers or putlogs can be conveniently used and it will be seen
that the method of attaching the ledgers and putlogs to the uprights or posts may be
applied to various other constructions other than scaffolds or trestles.
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. In scaffolding and the like the method of attaching horizontal supports such
as ledgers and putlogs to their vertical supports or posts substantially as described
herein and illustrated in the accompanying drawings.
2. The method and means of constructing scaffolding trestles and the like
substantially as described herein and illustrated by the accompanying drawings.
