PROVISIONAL SPECIFICATION.
Improvements in the Construction of Tents and Marquees.
We, MARY ANN BARNBY, of Great Western Arcade, Birmingham in the County
of Warwick, truding as "Barnby & Co.," and ERNEST MARQUOIS BARNBY of the
same place, Manufacturer, do hereby declare the nature of our said invention to be
as follows:
The object of this invention is to manufacture tents and marquees in such a
manner as to avoid the use of central poles; to simplify the erection, and to increase
the stability, when erected.
At each end of the tent or marquee, we form an A frame, consisting of two poles,
united at their upper ends, and spread out at their lower ends to the width of the
tent. To these poles horizontal cross poles are bolted or hinged near the apex of
the triangle. These cross poles are made equal in length to the width of the tent.
Or, instead of these cross poles, struts may be hinged or otherwise fitted to the
diagonal poles, so as to fold thereupon, when out of use.
Longitudinal stay ropes are fitted, from one A frame to the other, the rope to
the apexes forming the ridge of the roof, and the ropes from one cross pole to the
other forming the eaves.
Guy ropes are fitted to the apexes and the cross poles, or their equivalents,
the ends of the ropes being secured to ground pegs outside the tent.
The tent or marquce is covered in, in the usual manner, the whole of the enclosed
space being clear of poles or other obstructions..

COMPLETE SPECIFICATION.
Improvements in the Construction of Tents and Marquees.
We, MARY ANN BARNBY, of Great Western Arcade, Birmingham, in the County
of Warwick, trading as "Barnby & Co.," and ERNEST MARQUOIS BARNBY, of the
same place, Manufacturer, do hereby declare the nature of our said 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 manufacture tents and marquees in such a
manner as to avoid the use of central poles: to simplify the erection; and to
increase the stability, when erected.
At each end of the 'tent or marquee, we form an A frame, consisting of two poles,
united at their upper ends, and spread out at their lower ends to the width of the
tent. To these poles horizontal cross poles are bolted or hinged near the apex of
the triangle. These cross poles are made equal in length to the width of the tent.
Or, instead of these cross poles, struts may be hinged or otherwise fitted to the
diagonal poles, so as to fold thereupon, when out of use.
Longitudinal stay ropes are fitted, from one A frame to the other, the rope to
the apexes forming the ridge of the roof, and the ropes from one cross pole to the
other forming the eaves.
Guy ropes are fitted to the apexes, and the cross poles, or their equivalents, the
ends of the ropes being secured to ground pegs outside the tent.
The tent or marquee is covered in, in the usual manner, the whole of the enclosed
space being clear of ropes or other obstructions.

page_text: And in order that our said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.
Fig. 1 is an elevation of one of the A frames, and Fig. 2 is an elevation of Fig. 1,
at right angles thereto.
a a are the two diagonal poles of the A frame, hinged together or otherwiso
united at their upper ends. is a cross pole, which may be formed in two parts,
hinged together, fitted to the dingonals a a by bolts or other ordinary fastenings.
c. is a rope fastened to the two apexes, to form the ridge of the roof. d is one of
the ropes fastened to the cross poles bb, to form the eaves of the roof.
ee are the
top guy ropes, and ff are the side guy ropes, which are kept taut by means of the
main guy ropes g g in the usual manner.
Instead of the cross poles bb, we sometimes fit struts h h, as shown by dotted
lines in Fig. 1. These struts.are hinged or otherwise attached to the diagonals a a
and act as substitutes for the cross poles bb.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The improved construction of tents and marquees, by means of two A frames,
or their equivalents, placed at each end of the tent, for the purpose of providing a
clear space and dispensing. with central and corner poles, substantially as herein
before described and illustrated by the drawings.
2. The improvements in the construction of tents and marquees, substantially as
herein before described and illustrated by the drawings.
