VISIONAL AMBULANCES AND OTHER PURPOSES."
"
PROVISIONAL SPECIFICATION left by the said Casimir Honoré Tollet at
the Office of the Commissioners of Patents on the 10th May 1878.
CASIMIR HONORÉ TOLLET, of Paris, Rue d'Amsterdam, No. 21, Civil Engineer.
FIXED OR MOVABLE HUTS FOR PROVISIONAL AMBULANCES AND OTHER PURPOSES.",
My Invention relates to the construction of fixed or moveable huts available as
provisional ambulances, lodgings for troops or bodies of men and such like purposes,
the object of such construction being to provide accommodation cheaply and rapidly
by the use of materials readily accessible, arranged in such a manner as to give
warm, healthy, and water-tight shelter.
In all cases, whether for stationary or moveable huts, I employ for the structure
the sectional form of a Gothic or pointed arch, springing either from the ground or
from a low base wall or plinth.
For stationary huts I build the low side walls of brickwork, concrete, or other
suitable material, introducing at their upper parts courses of perforated bricks for
ventilation. On those walls I place iron ribs or principals bent to the arched form,
and meeting at the apex or ridge. I tie these together by tie rods, and between
the ribs I fill in with hollow bricks, which J cover externally with wooden planks,
nailing over these zine sheet or tarred felt or paper. I floor such huts with
a layer of gravel or cinders covered with concrete, and then with a layer of
asphalt.
For moveable huts I employ arched ribs made of iron of H section, which at the
bottom are secured by angle pieces to longitudinal foundation plates of like section,
and at the top are in like manner secured to a longitudinal ridge piece, being tied
together at intervals by bolts.

page_text: To the two foundation plates I secure by angle pieces cross bars, on which, lay
the floor.
I cover in the carcase in the following manner:-To each principal I bolt on
each side of it pieces of wood narrower than the space between the ribs, and in the
grooves left between these ribs and the edges of the wooden pieces I insert boards,
thus forming a double casing enclosing an air space.
I cover the exterior boards with zine or pitched felt or paper, or I employ for the
exterior covering fenther edged boards, each overlapping the board below it.
Instead of employing iron of H section, iron of T section may be used, the con-
struction of the wooden filling-in being in this case so far modified that the pieces
of wood bolted on each side of the principals are made wide enough to extend to
their outer edges, so that the exterior timbering can be nailed upon them.
The principals may be made of wood cut to arched-shape bolted together in
several thicknesses, crossing joints.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Casimir Honoré Tollet in the Great Seal Patent Office on the 14th
October 1878.

"FIXED OR MOVABLE HUTS FOR PROVISIONAL AMBULANCES AND OTHER PURPOSES."
My Invention relates to the construction of fixed or moveable huts available
as provisional ambulances, lodgings for troops or bodies of men, and such like
purposes, the object of such construction being to provide accommodation
cheaply and rapidly by the use of materials readily accessible, arranged in such a
manner as to give warm, healthy, and water-tight shelter.
In all cases, whether for stationary or movable huts, I employ for the structure
the sectional form of a Gothic or pointed arch, springing either from the ground or
from a low base wall or plintl.
For stationary huts I build the low side walls of brickwork, concrete, or other
suitable material, inttoducing at their upper parts courses of perforated bricks for
ventilation. On these walls I place iron ribs or principals bent to the arched form,
and meeting at the apex or ridge. I tic these together by tie rods, and between
the ribs I fill in with hollow bricks which I cover externally with wooden planks,
nailing over these zinc sheet or tarred felt or paper. I floor such huts with
a layer of gravel or cinders covered with concrete, and then with a layer of
asphalt.
For moveable huts I employ arched ribs made of iron of H section, which at tho
bottom are secured by angle pieces to longitudinal foundation plates of like section,
and at the top are in like manner secured to a longitudinal ridge piece, being tied
together at intervals by bolts.

page_text: Figs. 8 and 9 shew a part side view and part vertical section of a principal made
of wood. This is composed of three layers of planks n, n, secured together by screw
bolts o, o, and arranged so as to break joint. To these principals inner and outer
coverings of wood p, p, are secured, having an air space between them as in the
previous cases.
The outer covering may be made with the boards overlapping as shewn, so as to
prevent the rain from entering between the joints.
Having thus described the nature of my said Invention and in what manner the
same is to be performed, I claim,—
First. Constructing portable huts of arched ribs or principals secured at their
base to longitudinal plates tied together by transverse ties, the spaces between the
principals being enclosed by a double covering of wood or other material with air
spaces between, substantially as herein described.
Second. In portable huts, such as are referred to in the preceding claim, securing
the double covering to the principals of H section by fixing on the webs of the
principals wood cheeks to which the covering is attached, substantially as herein
described.
Third. In portable huts, such as are referred to in the first claim, the use of wood
or motal boxing for enclosing the spaces between the principals when these are
made of iron, substantially as herein described.
Fourth. The construction of wood principals with double wood covering for
portable huts as herein described with reference to Figs. 8 and 9 of the
Drawings.
Fifth. The combination of parts for forming portable huts as herein described
with reference to Figs. 3 to 7 of the Drawings.
Sixth. The combination of iron principals, with brick walls and hollow brick
covering, for permanently fixed huts, substantially as herein described with reference
to Figs. 1 and 2 of the Drawings.
In witness whereof, I, the said Casimir Honoré Tollet, have hereunto set my
hand and seal, this Eighth day of October, in the year of our Lord One
thousand eight hundred and seventy-eight.
