IMPROVEMENTS IN THE CONSTRUCTION OF PORTABLE BUILDINGS AND SIMILAR STRUCTURES
Year: 1884

page_text: COMPLETE SPECIFICATION.
I ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex
Engineer do hereby declare the nature of this invention for "IMPROVEMENTS IN
THE CONSTRUCTION OF PORTABLE BUILDINGS AND SIMILAR STRUCTURES," and in
what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The simple and movable trestles or frames which form the object of the present
invention may serve as supports or uprights for shelves for use in bread or biscuit
bakeries, for stowage, for use in shops, for goods, fabrics, utensils, camp furniture,
and the like.
In these cases the trestles or supports are used with ledges planks or rafters and
the like.
For use as sleeping accommodation all kinds of hammocks may be employed with
these frames but it is more practical to use two empty sacks and two ledges forming
a folding bedstead and these are extended in rows one above the other in the
several stories" of the frames.
The ledges are held at a suitable distance from one another by two small cross
pieces at their ends.
The trestles or frames may be equally used for tables, desks, beds, stairs etc.
By means of their accessories they may be very conveniently used' as a framing
to form camp barracks and in such case may be readily covered with tarpaulins,
curtains and fitted with gables to form temporary structures and the like.
In figure 1 of the annexed drawings the whole of this system is illustrated; it
consists substantially of trestles formed into trusses A. B by accessory pieces and
by their combination a bay or compartment is formed. The intermediary bays B
differ from those at the ends (A. C.) only by the shape of the foot or bottom part
which consists of a crossbar and several stays.
Each trestle or frame consists of a foot or bottom part with two uprights one of
which is shown in detail in figure 2, a cross bar such as used for trestles, an
ordinary crossbar and a suitable number of intermediary pieces. The parts are
connected by slides whose shape is represented in fig: 3.

page_text: Figure 1 clearly shows how the frames may be united into trusses and these into
bays. The intermediary pieces are simple ledges or brackets, say of pine, all the
other parts may be made of seasoned oak and are furnished with fittings of say
iron which may be screwed or rivetted so that in use their manipulation is simple
and rapid without. diminishing their solidity.
Such a trestle-tent may be covered by tarpaulin forming gables curtains and
the like. The gables may be pieces of linen of suitable size having at the top a
cloth window and at bottom a linen band which fits each side to the tarpaulin
furnished with strong fastenings.
In the remaining figures of the drawings fittings are represented which may 1
conveniently be used in connection with the trestles, but it will be obvious that
the form of these fittings is immaterial as numerous varieties of such fittings may
be employed as will be very readily understood.

Figure 4. shows how the parts are connected to form a gable and figure 5 shows
the top piece with a hook to connect it with another corresponding piece.
Figure 6. shows a cross piece for the trestles and its metal fittings.
Figures 7 and 7 show a hinge such as may be used in connection with the ridge-
piece, of a structure erected according to this invention.
Figure 8 screw for use with the stays.
Figures and 9b show the construction of a ferrule or bottom piece for a king
post or an upright.
Figures 10 and 10b represent a tip or cap for a post.
Figure 11 shows a cross bar with hooks to engage with corresponding staples
or eyes.
Figure 12 shows the construction of a tie piece or bearer.
13 and 13 show a hinge which may serve to connect rafters.
Figures 14. 15. and 15b show ties or bands for uniting divers parts.
Figure 16 and 16 show a cap for an upright Figure 17 and 18 are binges for use
with ties or braces.
Figures 19 and 19b show the construction of a staple for fixing the braces of the
trestles.
Figure 20 and 20 show a collar forming 4 staples.
Figures 21 show a tip for an upper tie fitted with a set screw.
Figs 22 and 22b show the inner side of the ties for the trestles.
Figures 23 and 23b outer views of the same.
Figure 24 a small socket plate.
Figure 25 another form of the same.
Figure 26 a turnbuckle fastener fixed on a plate and having a dowel, this may
be used for bottom plates.
Figure 27 shows a turnbuckle fastening mounted on a dowel plate and serving
for ties Figs. 28 and 28 ferrule for the inside of a tie bar or strut.
Figures 29 and 29b show a turnbuckle fastening on a simple plate and used in
connection with a socket plate.
Figure 30 and 30 show a tie piece with 3 staples and serving for the end pieces
of a structure.
Figures 31 and 31b show a tip or cap for a post.
Figures 32 and 32b show a bolt fastening for cross pieces. Figures 33 and 33b
hook with an angle piece for the ridge of a structure Figures 34 and 34b simple
hook for principal rafters and ridge pieces. Figure 35 shows a tenon brace piece.
Figure 36 is a mortice brace pieces. Figure 37 represents a morticed plate serving
as a base for an upright. Figures 38 and 38 show a tip for the top piece of a
gable. Figures 39 and 39b simple hook for the top of an upright. Figure 40 shows
a mortice plate. Figure 41 represents a tenon claw or fastening. Figure 42 and 42
show a dowel plate for the lower parts of the structure Figure 43 and 43 show
simple eyebolts for the rafters Figures 44 and 44° a simple form of fastening
therefore. Figures 45 and 45b illustrate the construction of a fastening plate with

page_text: dowel and tenon; figure 46 shows a staple for rafter ends. Figure 47 represents a
ridge piece. Figure 48 shows an iron fastening bolt or pin. Figure 49 shows a
plate with a conical dowel serving as a base for posts.
All the said fittings are so simple that their construction is evident from the
drawings, their particular form or arrangement is moreover immaterial and capable
of almost endless variety. It is also obvious that the essential feature of this
invention is the construction of barracks, temporary dwellings, tents, sheds or
similar erections by means of frames that can easily be fixed together and taken
apart and which may be covered with tarpaulings, canvas or any suitable material.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondent, I declare that what I claim is: The herein
described construction of Barracks, sheds, tents or similar structures consisting of
light tressels or frames connected arranged and covered substantially as set forth
and illustrated in the drawings.
