An Improved construction and arrangement of Rubber for Abrading
the Surface of Rubber Bricks or like Substances.
HENRY JOHN SEYMOUR MOUNTAIN, Builder, Bude House, Heyward Road,
Barton Hill, Bristol, do hereby declare the nature of this invention to be as
follows:-
I employ a series of flat cutters or scrapers, set on edge, separated by washers,
and bolted, riveted or clamped together.
The under or working edges of the cutters may either be straight so as to produce
a flat surface on the brick, or they may be similarly modified to any desired
form, so that when the whole set of cutters is worked to and fro transversely
across the brick the surface thereof is either equally or differentially abraded.
The two outermost cutters may be lengthened and curved upwards to bear
handles.

An Improved construction and arrangement of Rubber for Abrading
the Surface of Rubber Bricks or like Substances.
I, HENRY JOHN SEYMOUR MOUNTAIN, Builder, Bude House, Heyward Road,
Barton Hill, Bristol, 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:-
I employ a series of flat cutters or scrapers, set on edge, separated by washers,
and bolted, riveted, or clamped together.
The under or working edges of the cutters may either be straight so as to
produce a flat surface on the brick, or they may be similarly modified to any
desired form, so that when the whole set of cutters is worked to and fro trans-
versely across the brick the surface thereof is either equally or differentially
abraded.
The two outermost cutters may be lengthened and curved upwards to bear
handles.
My invention will be clearly understood by reference to the annexed drawings.
Figure 1 perspective elevation of apparatus of flat form to be laid upon a table
or bench, over the grating like surface of which a rubber brick can be moved to
and fro between the handles, or as an article to be moved to and fro, or otherwise
on a rubber brick, if laid upon a table or bench.

Figure 3 perspective elevation, and
Figure 4 plan of a stepped apparatus provided with feet, so that the dust
from a rubber brick during the rubbing may sift through and so prevent the
spaces between the scrapers becoming clogged.
I have shown the scraping surfaces on edge as a flat for scraping the rubber
bricks flat or square faced but by making the top edges of the scrapers of curved,
undulatory, or spiked shaped, any desired contour can be given to the face of a
rubber brick according to the position it has to occupy within or to a building.
The rubber brick abrader of my invention consists of steel strips A with holes
and distanced apart by washers B, through which and the holes, the bolts C pass
and the series of strips A which form a kind of grating held firmly in position by
the screw nuts D, or such bolts of pin shape may have their ends riveted for
permanent fixture of the steel strips.
The outside strips E may be of greater length and be of the same thickness as
the plates themselves, as at Figure 1, or of stouter material, as at Figures 3 and 4,
to ensure great stiffness and said end strips may be curved and be provided, with
handles F, F, in any desired manner or a diagonal cross bar may be fitted as a
handle, which will give freedom of action to the operative when working the
apparatus over a brick when rubbing it down.
The arrangement of the steel strips as scrapers A¹ similarly distanced and
located shown at Figures 2 and 3 and provided with feet G, G, serve to rub down
one face of a brick, and these scrapers may be of the desired shape to chamfer,
to score, or to make a pattern after the ogee or other moulding, as desired.
This tool will rub down two sides of a rubber brick at once and finish it square.
I prefer that the scraper strips A¹ be separated from the strips A and held in
place by separate bolts C¹ passed through the ears E¹.
The outside strips may have their holes elongated to allow for adjustment of
the steel strips A.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:
The construction of rubbers for abrading the surfaces of rubber bricks from a
series of steel strips A and washers B secured together by bolts or rivets C to side
strips E the several parts being arranged adjustable or not as and for the purposes
specified.
