Improved Cement Step.
I, DAVID JANZI, Contractor for Cement Work, of St. Imier, Canton of Berne,
Switzerland, do hereby declare the nature of this invention to be as follows; —
The steps made of compressed or agglomerated cement for staircases as in use
hitherto have the advantage of being more economical than those made of granite,
rock or other stone, whilst almost equally strong. The chief inconvenience in
the use of cement for such steps consists principally in the fact that the outside
parts, which are trodden on, very quickly wear away; besides which, the cement
being porous, grease spots show up very plainly.
The step forming the object of this invention has all the advantages of stone
as well as of cement; it is made of cement of good quality and its outside parts,
which are exposed to wear, are formed of small pebbles or pieces of silex or hard
stone introduced into the cement in the course of manufacture, the outside parts
being milled or partially rubbed down by any process, exposing the texture of
the pebbles or pieces of hard stone, and when polished having a very handsome
effect, similar to mosaic work.
The garnishing with pebbles or pieces of hard stone need not be confined to
the parts exposed to wear but may be applied to other outside parts or, in fact,
all such.
Thus formed, this step not only has a handsome appearance, but stands wear as
well as those made of rock or granite. It can be produced by compression,
agglomeration or in any other suitable manner, and in all shapes and sizes.

I, DAVID JANZI, Contractor for Cement Work, of St. Imier, Canton of Berne,
Switzerland, 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 steps made of compressed or agglomerated cement for staircases as in use
hitherto have the advantage of being more economical than those made of granite,
rock or other stone, whilst equally strong. The chief inconvenience in the use
of cement for such steps consists principally in that the outside parts, which are

grease spots show up very plainly.
The step forming the object of this invention has all the advantages of stone
as well as of cement. The accompanying drawing is a perspective view of a
step constructed according to this invention. The step a is made of cement of
good quality and its outside parts, which are exposed to wear, are formed of small
pebbles or pieces of silex or hard stone, a, a¹, c", introduced into the cement in
the course of manufacture, the outside parts being milled or partially rubbed
lown by any process, exposing the texture of the pebbles or pieces of hard stone,
and, when polislied, having a very handsome effect, similar to mosaic work.
The garnishing with pebbles or pieces of hard stone need not be confined to
the parts exposed to wear but may be applied to other outside parts or, in fact,
to all such.
Thus formed, this step not only has a handsome appearance, but stands wear as
well as those made of rock or granite. It can be produced by compression,
agglomeration or in any other suitable manner, and in all shapes and sizes.
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:-
A step made of cement, to be used for staircases, the outside parts of the step
being garnished with pebbles or pieces of hard stone of any kind, supported in
the body of the cement, and the surfaces smoothed or polished by any suitable
process.
