COMPLETE SPECIFICATION.
Improvements in Gabled Roofs.
I, FERDINAND BOSSHARDT, of the firm of F. Bosshardt & Co., of 4 Corporation
Street, Manchester, in the County of Lancaster, Engineer and Patent Agent, do hereby.
declare the nature of this invention which has been communicated to me from abroad
by Hercelle-Leruste, of Tourcoing, in the Republic of France, Manager, and in what
manner the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
My invention relates to improvements in gabled roofs for factories, dye-houses,
laundries, and like buildings, where steam, smoke, gases or other vapours accumulate
and has for its object to facilitate the escape of the same which is injurious and often
causes great inconvenience to the operators. To obviate these defects my invention
consists chiefly in forming the upper portion of gabled roofs with an opening in
connection with one or more oscillating covers or hoods having its point of oscillation
either above or below the gable point and with or without plain or toothed arms
This
actuated by means of plain or toothed pulleys and cords or chains respectively.
may be carried out in various ways.
And in order that my invention may be more fully understood, I have caused to be
appended hereunto one sheet of drawings, which represent a cross section of a shed
showing my invention applied in four different manners.
Fig. 1 shows the application of a radial cover or hood, by means of which both sides
of the roof can be closed or opened simultaneously or independently of each other.
Fig. 2 shows the application of a straight cover or hood in a position to exclude the
wind from the left, while the right side of the roof remains open.
Fig. 3 shows the cover or hood positioned vice versa to Fig. 2.
Fig. 4 shows the application of a segmental cover or hood in its central position.
Fig. 5 in a position to exclude wind from the left, while the right side remains open
and
Fig. 6 in a position vice versa to Fig. 5.
Fig. 7 shows a modification of Figs. 4, 5 & 6, consisting in the application of a
balance weight a to the segmental cover or hood, so as to retain the latter in a central
position and in the use of two trap doors b, below the same hinged onto the cross beam
of the gable which serve to completely close the opening in the roof. The cord or
chain by means of which the cover or hood is actuated, in this case, is fastened to the
trap door band passed through an eye on the segmental cover or hood and round a
pulley, so as to cause the said trap door to move upwards on the cover or hood being
actuated by means of the said cord or chain and thus completely close the roof.
It will thus be understood that the various applications of the said cover or hood
permits of excluding the wind altogether or on one side of the roof only, while the
open portion permits the access of fresh and the escape of bad air, at the same time
preventing the access of rain.
The said cover or hood may be made of any suitable material, such as glass,
zinc, etc.
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 :-
In gabled roofs of the kind hereinbefore referred to.
1st. The general application and arrangement of parts hereinbefore described,
operated substantially as and for the purpose specified.
2nd. The openings formed in the upper portion of the gabled roof in combination
with one or more oscillating covers or hoods having their point of oscillation either
above or below the gable point, substantially as set forth.

page_text: 3rd. Providing the segmental cover or hood with a balance weight a, substantially
as and for the purpose set forth.
4th. The combination of the segmental cover or hood with two trap doors b,
substantially as and for the purpose specified.
Dated this 12th day of February 1890.
