page_text: LETTERS PATENT to John Edward Walsh of Halifax Leeds and Bradford all
in the County of York Patent Agent and Consulting Engineer for an
Invention of IMPROVEMENTS IN JOINTS, BEARERS, AND COVERINGS, FOR
ROOFING, PILLARS AND OTHER BUILDING MATERIAL communicated to him
from abroad by Martin George Mitter and Dr Ludwig August Hoffman
both of Berlin in the Empire of Germany
PROVISIONAL SPECIFICATION left by the said John Edward Walsh at the
Office of the Commissioners of Patents on the 9th December 1882.
JOHN EDWARD WALSH of Halifax, Leeds and Bradford all in the county of
York, Patent Agent and Consulting Engineer. "IMPROVEMENTS IN JOINTS, BEARERS,
AND COVERINGS, FOR ROOFING, PILLARS, AND OTHER BUILDING MATERIAL." Com-
municated to me from abroad by Martin George Mitter and Dr Ludwig August
Hoffman both of Berlin in the Empire of Germany
My improvements consists in various forms and arrangements of metal plates, to
form joints, bearers and channels for roofs, coverings platforms, bridges and ships
bottoms.
These coverings consists of hollow metal plates of various forms, so arranged and
joined together as to render the joints of roofs water tight, and in some cases forming
troughs to carry away the water falling upon the same and a method of attaching
the same to the roof also in shaping plates for joining and protecting the joints of
the rafters. In some cases, circular, partly circular and angular pieces of metal are
employed forming bearings or coverings for joints as well as forming troughs for
carrying away the water.
The shape and arrangements of such plates for building purposes are formed so
as to give greater strength, to be simple and easily put together, to hold the covering
fast, and to avoid nailing as much as possible, and to protect the building and
material employed therein.

DESCRIPTION OF DRAWINGS
Figs. 1, 15 and 26 shew profiles of hollow material which is applied as bearers,
beams and rafters
Figs 16 and 19 shew some profiles for pillars.
Figs, 20 and 23 shew profiles for pillars, laths, and ladderbeams.
Figs. 24; 25 and 26 show some examples of roof tops; in which the hollow, material
is used as tops, bearers, and rafters.
In Fig. 1 is represented a simple profile of a rafter the same form, two boxes with
a covering plate bent over it under which the covering material is put in.
Figs 2. and 3. shew another simple profile, however, without covering plate the
penetrating rain water runs away through: the channel formed.
Fig. 4 shews a similar profile with patches bent on the side and round bottom
which is let into a wood support and nailed
Fig. 5 shews a hollow profile combined of several boxes which bears on an axle
tree tin covering, therefor, the middle cross pieces is so high, the same can however
be lower for less thick covering material, a half round top forms here likewise the
'covering of the joint.,
J
Fig. 5 shews a box bearer in simple form as a bearer bent in one piece.
Fig. 5B shews a box bearer like the former, with profile laid in for strengthening.
Fig. 6 shews
box profile of a beam put together from several shaped
profiles with rolled joints on the lower edges, the tops may also be rivetted on the
middle cross piece.
เ
Fig 7 shews the former profile executed in a very low height without rolled
joints and upon a wooden bottom, the top as well as the profiles are nailed and the
former one, with especially tapered nails (through indiarubber supports) the profile
is however nailed with the side patches, the two channels formed take away the
rain water; corresponding rabbets are worked into the beams in which the hollow
profile is laid.
5.
... 12.
..
Fig. 8 shews a simple hollow profile likewise also a good support which is not
provided with corresponding rabbets, the nailing is done on the side.
Fig. 9 shews a hollow profile in which the rolled joints lie above; the top is pushed
here as by the former one over the middle cross beam in a T form.
Fig. 10 shews a hollow profile in which the top is bent from one piece; within the
middle cross beam is laid in besides a special shape of iron for strengthening which
is connected by some rivets with the chief profile...
1.
Fig. 11. shews a double T profile. in which upper part lengthwise the head is
pushed in.
1
'
Fig. 11 shews the imitation of one of the most usual T irons bent from one
piece.
Fig. 12 shews a simple round profile, with a lengthwise slit on the upper side in
which the covering material is pushed in.
Fig. 13 shews a round profile a little deviating from the former one, the fixing
of the covering material is done here by cramp irons especially pushed in

page_text: Fig 14 shews a slender hollow profile specially for glass roofs, the same is bent
from one piece with an inlaid strengthening iron and a particularly pushed up
head.
Fig. 14 shews a simple step profile likewise very much adapted for glass roofs.
Fig. 15 shews a hollow profile for the gable wall with a rabbet for the same (for
example axle tree tin).
Figs. 16 and 19 shew simple column profiles, which can be besides brought in
any other shape. In Fig. 19 is also shewn the appliance of a special central pipe
for heating or circulation purposes.
Figs 20 and 23 shew simple profile for posts, laths, ladderbeams, which through
their shape receive a greater stability and do not possess any sharp edges.
Figs 24 and 25 shew two examples of gable ends with rafters and the top
covering may be choosen from the profiles shewn before or also in a similar way
and according to modifications.
Fig. 26 shews the cross cut through right side spars of the Fig 25 which is
provided with covering in the form of staircase.
All the profiles represented and described there can consist of any length choosen,
in order to form greater lengths they are pushed on a shorter piece that they may
possess superficial firmness to secure the parts against length shifting, several rivets
are put in. In compound profiles especially for columns if they do not consist of
one piece the joints are always laid in such a way that the upper tin plates with its
free edges falls in one of the side column's edge; but it is advantageously laid to an
inner edge as Fig. 18 shews.
Having thus fully described the nature and particulars of this my said invention
and the manner in which the same is to be performed I would have it understood
that what I claim as the invention to be secured to me by the hereinbefore in part
recited Letters Patent is.—-
1 The support for the covering material formed with a channel for rain or other
water as represented in Fig 1 and 15.
2 That beneath the covering by bearers, beams or spars Figs 5. 6. 7. or 10 or
either the respective pillar there remains open a channel for air circulation.
3 That the covering material is only pushed in, therefor not fixed.
4. That through particular laying in of suitable profile iron shewn at Figs 10
14. 24 and 25 the capability of resistance of the profile can be increased.
5 The profiles chiefly so combined to be used for obtaining greater strength the
single ones having only to be pushed together and are secure without special
connection.
6 The head for protecting the covering material over the hollow profiles which
is pushed over and without further means of fixing firmly lies on and holds the
covering fast thus avoiding nailing
7. The combination of hollow profiles with wood supports and a nailing on one
side especially protected see Figs 7. and 8.
In witness whereof I the said John Edward Walsh have hereunto set my
hand and seal this eighth day of June in the year of our Lord one thousand
eight hundred and eighty three.
