Year: 1862

page_text: LETTERS PATENT to Bernardo Fabbricotti, of 150, Leadenhall Street, for
the Invention of "A POLISHING AND GRINDING BELT FORMED OF LEATHER OR
OTHER FLEXIBLE OR PLIABLE MATERIAL, HAVING PLUGS COMPOSED OF EMERY OR
OTHER GRITTY SUBSTANCE, AND A PROPER CEMENT INSERTED IN IT SUBSTAN-
TIALLY." A communication from abroad by George Rutger Vanderbilt,
of 116, Nassau Street, New York, United States of America.
Sealed the 7th November 1862, and dated the 21st June 1862.
PROVISIONAL SPECIFICATION left by the said Bernardo Fabbricotti at
the Office of the Commissioners of Patents; with his Petition, on the
21st June 1862.
I, BERNARDO FABBRICOTTI, of 150, Leadenhall Street, do hereby declare the
nature of the said Invention for "A POLISHING AND GRINDING BELT FORMED OF
LEATHER OR OTHER FLEXIBLE OR PLIABLE MATERIAL, HAVING PLUGS COMPOSED OF
EMERY OR OTHER GRITTY SUBSTANCE, AND A PROPER CEMENT INSERTED IN IT SUBSTAN
TIALLY," to be as follows:-
The ordinary belts used for polishing and grinding cutlery and other articles.
of metal are composed generally of leather, and fitted either over two rollers
or wheels so as to form an endless belt, or secured to the periphery of a wheel
so as to form what is commonly termed a "polishing wheel." The cutting,
grinding, or polishing capacity is obtained by placing emery on the surface of

page_text: the belt, and this requires to be done frequently as it graduany works on O
the belt or wheel.
The object of the Invention is to obtain a polishing belt which will retain its
cutting, grinding, or polishing capacity until it is completely worn out, without
requiring to be fed or supplied with emery, and to this end I insert in the belt,
at suitable or proper distances apart, plugs extending entirely through the belt
so as to form permanent polishing or cutting surfaces, as herein-after fully
shown and described.
In the accompanying Drawings illustrating this Invention, Figure 1 is a
face view of the Invention; Figure 2 a transverse section of the same taken
in the line x, x, Figure 1; Figure 3, a longitudinal section of the same applied
to two wheels; Figure 4, a longitudinal section of the same applied to the
periphery of a single wheel. Similar letters of reference indicate corresponding
parts in the several Figures.
A represents a belt, which may be of leather, india-rubber, or other suitable
flexible fabric. Leather, however, is the material most generally used for
polishing belts. This belt is perforated with holes at a suitable distance apart,
and in the holes plugs B are fitted, the thickness of which corresponds with
the thickness of the belt. The plugs are made of a slight taper form, the
smaller diameter being outermost in order to prevent them dropping out from
their holes, a contingency which would otherwise be liable to occur. If the
belt be used as and endless one, as shown in Figure 3, it will be found necessary
to line the belt with canvass or leather. The plugs are composed of emery or
other gritty substance and any suitable cement properly mixed and 'moulded
in the desired form. Liquified quartz is the substance I design to use as a
cement, but I do not confine myself to any particular kind. The holes in the
belt should be cut of slightly taper form to correspond with the taper of the
plugs, and the latter may be cemented in the holes. The plugs may be of
cylindrical form in their transverse section. This would be probably the most
preferable shape, as the holes in the belt which receive them can be more
readily cut in that form than in any other. As regards the working of the
belt practically, however, any form of plug may be used. The belt should
have a sufficient number of plugs inserted in it to ensure a requisite area of
cutting, grinding, or polishing surface, at the same time it will be observed
that the belt must not be cut away so much as to render it liable to break or
part. The arrow in Figure 1 shows the direction in which the belt runs. The
plugs B, it will be seen, form permanent cutting, grinding, or polishing-sur-
faces, which will last as long as the belt, as they form a part of and extend
entirely through it. Hence the cutting, grinding, or polishing capacity of the

page_text: belt will be constant. The ordinary belt with emery simply sprinkled upon it
varies materially in its action owing to the emery working off from it and the
inattention of workmen in keeping it properly supplied. A great deal of
emery is also wasted by their use.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Bernardo Fabbricotti in the Great Seal 'Patent Office on the
13th November 1862.
⚫ TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BERNARDO
FABBRICOTTI, of 150, Leadenhall Street, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of June, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Bernardo Fabbricotti, Her special licence that I, the said
Bernardo Fabbricotti, my executors, administrators, and assigns, or such
others as I, the said Bernardo Fabbricotti, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "A POLISHING, AND GRINDING BELT FORMED OF LEATHER OR OTHER FLEXIBLE
OR PLIABLE MATERIAL, HAVING PLUGS COMPOSED OF EMERY OR OTHER GRITTY SUB-
STANCE, AND A PROPER CEMENT INSERTED IN IT SUBSTANTIALLY," a communication
to him from abroad by George Rutger Vanderbilt, of 116, Nassau Street, New
York, United States of America, upon the condition (amongst others) that
I, the said Bernardo Fabbricotti, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands, and seals, should
particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Bernardo Fabbricotti, do hereby
declare the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement :-
.
The ordinary belts used for polishing and grinding cutlery and other articles

page_text: of metal are composed generally of leather and fitted either over two rollers,
or wheels so as to form an endless belt, or secured to the periphery of a wheel
so as to form what is, commonly termed a "polishing wheel." The cutting,.
grinding, or polishing capacity is obtained by placing emery on the surface of
the belt, and this requires to be done frequently as it gradually works off from
the belt or wheel.
The object of my Invention is to obtain a polishing belt which will retain
its cutting, grinding, or polishing capacity until it is completely worn out
without requiring to be fed or supplied with emery, and to this end I insert in
the belt, at suitable or proper distances apart, plugs composed of emery or
other gritty substance and any suitable cement, said plugs extending entirely
through the belt, so as to form permanent polishing or cutting surfaces, as.
herein-after fully shown and described.
In the accompanying Drawings illustrating this Invention, Figure 1 is a
face view of my Invention; Figure 2, a transverse section of the same taken in
the line Figure 1; Figure 3, a longitudinal section of the same applied to two.
wheels; Figure 4, a longitudinal section of the same applied to the periphery:
of a single wheel. Similar letters of reference indicate corresponding parts in
the several Figures.
A represents a belt, which may be of leather, india-rubber, or other suitable:
flexible fabric. Leather, however, is the material most generally used for
polishing belts. This belt is perforated with holes at a suitable distance apart,.
and in the holes plugs B are fitted, the thickness of which corresponds with
the thickness of the belt. The plugs are made of a slight taper form, the.
smaller diameter being outermost in order to prevent them dropping out from
their holes, a contingency which would otherwise be liable to occur. If the.
belt be used as an endless one, as shown in Figure 3, it will be found necessary;
to line the belt with canvas or leather. The plugs are composed of emery or
other gritty substance and any suitable cement properly mixed and moulded
in the desired form. Liquified quartz is the substance I design. to use as a
cement, but I do not confine myself to any particular kind. The holes in the
belt should be cut of slightly taper form to correspond with the taper of the
plugs, and the latter may be cemented in the holes. The plugs may be of

varies materially in its action owing to the emery working off from it and the
inattention of workmen in keeping it properly supplied. A great deal of
emery is also wasted by their use.
A belt for polishing, grinding, &c., formed of leather or other flexible or
pliable material, having plugs composed of emery or other gritty substance
and a proper cement inserted in it, substantially as herein shewn and
described.
In witness whereof, I, the said Bernardo Fabbricotti, have hereunto set
my hand and seal, this 13th day of November, in the year of our Lord
One thousand eight hundred and sixty-two.
