PROVISIONAL SPECIFICATION.
A Travelling Iron Roof.
JOHN LAING, Builder & Contractor 4 St. James Road Carlisle. I do hereby
declare the nature of this invention to be as follows:-
A travelling iron roof constructed of galvenized sheets, iron frameing & tie rods
fixed on flanged iron wheels to run on an elevated railway constructed on either
wood or iron pillars supported on the ground & braced with tie rods. The idea
is to meet a long felt want to protect from weather brick kilns where carried on
invariabley in the open field, it woud do away with the labour of running out
where permanent kilns are used, the advantage of such a roof would protect from
weather when setting & burning, & could be easily moved on another length setting
& burning going on without intermission.

COMPLETE SPECIFICATION.
A Travelling Iron Roof.
JOHN LAING Builder & Contractor No. 4 St. James Road Carlisle. I 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 primary object of proposed roof is to meet a long felt want in protecting
kilns of bricks while setting & burning from inclement weather, this work is to a
great extent carried on in the open field without any protection from the rain &
considerable loss is thus constantly being caused both in the diminution of the
quantity & the deteriation of the quality of the bricks made, besides being a
protection from the weather such a roof would cause a great saving of time, after
the kiln was set & got to burning, the roof could be moved forward & setting go
on continuously instead of waiting till the bricks are cool & run out which at
present has to be done where permanent kilns are used before the kiln can be got
ready for use again.
This roof could be used to great advantage for general purposes in such places
as dock yards, wharfs, engineers & contractors works, new buildings &c.
My scheme is to fix a continuous line of rails on pillars of such lengths as will
be best suited to meet each particular case for roof to travel upon, the drawing
No. 1 shows two horisontal rails R placed paralell supported by iron columns c,
& caps with flanges formed to receive the rails R, the columns c, are fixed into
the ground with cement concrete footings & bolted to same with wrot iron stay
bars S, as shown on plan No. 1.
The roof as shown on drawing No. 1. is made of wrot iron frame & covered
with corrugated iron, at terminus of principals of roof is formed a framework as
shown on detail A, for wheels to work in, the main tie rod of principal of roof
acting as axle for wheels on detail A. B represents a strong iron guard attached
to frame on each side of wheels to keep the roof from oscillating or getting off
the rails R. R. either by wind pressure or other cause, a stop will be formed at
each end of rails to prevent running over.
The roof may be formed in sections as shown on drawing No. 1, D, or otherwise
if required, where sections of roof meet they will be so arranged that one will
overlap the other & sheets so placed as to prevent rain coming through, the eaves

page_text: spout fixed in such a manner as to allow a drop with hollow stop end to prevent
leakage & will empty into a down pipe fixed to pillar. A clasp will also be so
constructed as to secure the sections together when placed in position, also a brake
attached to wheels in the form of a small wedge shaped shoe, so that the wheels
may be braked in any position required.
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
1st. The combination of frame with roof principals for locomotion, as shown on
detail A. at F.
2nd. For construction & use of guard as shown on detail A. at B. & main tie
rod acting as axle.
3rd. For the application of the several component parts as a whole for the
purpose of forming a travelling iron roof.
Dated this 28th day of August 1893.
