I CARL BRADER of. Oldenburgh in the Empire of Germany Mill Manager do
hereby declare the nature of my invention for AN IMPROVED COVERING FOR STEAM
OB HOT WATER PIPES, CYLINDERS AND BOILERS, AND IMPROVED APPARATUS FOR
PREPARING THE SAME and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :--
The invention relates principally to the utilization of artificially or otherwise
dried peat or turf for the purpose of covering steam or hot water pipes, cylinders
and boilers to prevent the radiation of heat therefrom, preference being given to a
very fibrous kind of peat or turf found in the Grand Duchy of Oldenburg.
The peat or turf is dried, by artificial means or otherwise until it is perfectly
deprived of moisture and assumes an appearance very much resembling cork, and
it is then formed into the required shape for covering the surface to which it is to
be applied by means of grinding or rasping rollers prepared and formed as herein-
after described.
The dried and ground peat or turf having been properly fitted round the pipe
or other surface is then secured thereto by coiling round it wire, cord, or metallic
bands to keep it in place and by uncoiling this the covering can readily be
removed.
The construction of the grinding or rasping rollers which I propose to employ
for reducing the dried peat or turf to the required form and dimensions for utilization
for this purpose will be readily understood on reference to the sheet of drawings
annexed to this Specification in which Figs. 1. 2. 3 and 4 represent various forms
of rollers for grinding or rasping the dried peat or turf.
The rollers are made of metal.
In Figs. 1. and 2 these rollers are formed with a spiral groove a, a which is filled
in with coarse emery or emery cloth cemented thereto.
In place of coarse emery or emery cloth I sometimes make the grinding or
abrading surfaces of the rollers of tin or other thin metal having holes pierced from
the back so as to leave a sharp burr on the face like a nutmeg or bread-grater..

page_text: Rollers of this construction and of various forms are employed for grinding both
the inside and the outside and edges of the pieces of dried peat or turf which may
be made in two or more sections according to the diameter of the pipe, cylinder, or
boiler, to be covered..
For pipes of small diameter I take blocks of the dried turf, and I bore them
through with boring tools made in the same way as the rollers and I thread these
blocks onto the pipes before they are connected together.
Fig. 3 represents a roller formed with circumferential grooves b, b adapted to
grind the insides, or interior surface and the radial edges at the same time, and
Fig. 4. is a similar roller to grind the outside or exterior surface. I also employ
other forms of grinding or abrading tools according to the form of the article to be
covered.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
First the use of artificially or otherwise dried peat or turf ground or rasped to
the required form for the purpose of covering pipes, boilers and cylinders to
prevent the radiation of heat therefrom and
Secondly I claim the particular construction of grinding or abrading rollers or
tools the grinding or abrading surface whereof is covered with coarse. emery or
with perforated tin or other thin metal substantially as herein before described and
illustrated by the drawings annexed for the purpose of grinding or reducing the
said dried peat or turf to the required form for such use.
