SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alexander Browne in the Great Seal Patent Office
on the 30th December 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
BROWNE, of the Firm of Browne and Company, Patent Agents, of 5,
Southampton Buildings, Holborn, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of June, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Alexander Browne, Her
special licence that I, the said Alexander Browne, my executors,
administrators, and assigns, or such others as I, the said Alexander
Browne, 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
Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF CASTERS," a commu-
nication to me from abroad by Adolphe Drevelle, Paul Petitjean, and
François Labbé, Manufacturers, all of Paris, in the French Republic, upon
the condition (amongst others) that I, the said Alexander Browne, my
executors or administrators, by an instrument 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 immediately
after the date of the said Lotters Patent.
NOW KNOW YE, that I, the said Alexander Browne, do hereby
declare the nature of the said Invention, and in what manner the

page_text: same is to be performed, to be particularly described and ascertained
in and by the following statement, that is to say :—
This Invention consists in constructing casters of several parts cut or
stamped out of sheet metal, and fitted together.
And in order to explain this Invention more fully I now proceed to
describe the details of construction and means by which this Invention
may be effected, reference being had to the illustrative Sheet of Drawing
accompanying these Presents, and to the numeral figures and letters of
reference marked thereon respectively, as follows :-

roller.
Figures 12, roller made in sheet metal cut or stamped out, and filled
at c with cardboard or paper pulp; b, the rolling surface of the roller.
Figures 13 are sectional and side views of copper discs used to
construct the improved casters.
:
Figures 14, roller made of two small discs of sheet metal ƒ, ƒ, of a
small tube d, and filled in at c with paper or cardboard, the exterior
being. varnished.
Figure 15 is a modified construction of roller hereafter described.
At each of the above-mentioned Figures similar letters of reference
are placed upon corresponding parts.
The piece represented at Figure 1 is cut or stamped into the shape
shown, then bent into the shape shown at Figure 2. The pieces. shown
at Figure 3 occupy and are soldered in the spaces marked A. at Figure 1,
the holes B therein being intended to receive the spindle C, as shown at
Figure 6, for connecting the caster to any article of furniture requiring
casters. The holes a, a, support the axis 6 of the roller of the caster;
the roller is provided with a tube across its centre, which fits upon and
revolves around the axis b, which is rivetted in the holes a, a.

The above parts are employed in the construction of casters having
one roller only.
To construct casters with a double roller or two distinct rollers arranged
side by side proceed as follows with reference to Figures 7, 8, 9, 10:-
Figure 7 shows the shape of the piece of sheet metal required to form
one side of the frame which carries the other parts of the caster;
Figure 8 shows the side of the double caster, with roller connected
thereto; Figure 9 shows the tube F, which carries the two rollers; bis
the axis passed through the tubo F; the ends of this axis are rivetted
to the side frame, as shown at Figures 7, 8, 10, 11; Figures 10 and 11
shew the shapo, of the side frames when cut out to form a joint, as at
C, Figure 8, through which passes an upright pin for connecting the
caster to the foot or leg of a piece of furniture.
For large casters the rollers are made in the manner represented at
Figures 12 and 13, where 6 marks a piece of sheet metal bent into the

page_text: shape shown, and its ends brazed or soldered together. a, a, are discs of
metal, the space between which at c is filled with paper pulp or other
suitable material, and finally the edges of the piece bare turned over to
hold the discs a, a, firmly in position. The hole at x is for the axis of
the roller to pass through.
For small rollers simple discs of metal fare employed, embracing
paper pulp, the whole being connected together by a tube = rivetted
over at its ends, the axis of the said roller passing through the tube z.
Figure 15 shows the periphery of the roller made irregular instead of
plain; the sides are turned over and embrace two discs of metal of the
shape shown at Figure 5, the space between the said dises being filled
in with paper pulp, cardboard, or other suitable substance.

Having now described the nature and object of this Invention for
Improvements in the Construction of Casters," as communicated to
me by my foreign correspondents, and the means by which it may be 1
effected, I hereby declare this Invention to consist in, and I claim,―
First. Constructing casters of several pieces of sheet metal cut or
stamped out and bent into shape and fitted with the other parts of the
caster in the manner abovo described with reference to the accompanying
Drawing.
Second. Constructing the rollers of casters by combining metal
with cardboard, paper pulp, or other like material, as above described
and represented.
In witness whereof, I, the said Alexander Browne, have hereunto
set my hand and seal, this Twenty-ninth day of December, in 1
the year of our Lord One thousand eight hundred and seventy-
five.
