page_text: LETTERS PATENT to George Haseltine, of the "International Patent
Office, No. 8, Southampton Buildings, Chancery Lane, in the County of
Middlesex, Civil Engineer, for the Invention of "AN IMPROVED MODE OF
AND MEANS FOR ATTACHING CASTERS TO THE STANDS OF SEWING MACHINES."
A communication from abroad by Myron Perry, of the City, County,
⚫ and State of New York, United States of America.
COMPLETE SPECIFICATION filed by the said George Haseltine at the
Office of the Commissioners of Patents, with his Petition and Declaration,
on the 21st November 1866, pursuant to the 9th Section of the Patent
Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the " Internationl Patent Office," No. 8, Southampton Buildings,
Chancery Lane, in the County of Middlesex, Civil Engineer, send greeting.
WHEREAS I am in possession of an Invention for "AN IMPROVED MODE OF
AND MEANS FOR ATTACHING CASTERS TO THE STANDS OF SEWING MACHINES," and
have petitioned Her Majesty to grant unto me, my executors, administrators,.
and assigns, Her Royal Letters Patent for the same, and have made solemn
Declaration that it has been communicated to me from abroad by Myron
Perry, of the City, County, and State of New York, United States of
America.

page_text: NOW KNOW YE, that I, the said George Haseltine, do hereby declare
that the following Complete Specification, under my hand and seal, fully
describes and ascertains the nature of the said Invention, and in what manner
the same is to be performed in and by the following statement, reference
being had to the annexed Drawings making a part of this Specification
The nature of the said Invention consists, first, in so attaching casters to
the legs of sewing machines that though a wheel or roller of large diameter
is used the said machines will not be elevated too high or changed materially
from their normal position; second, in attaching the casters- durably to a
small surface of iron by means of screws and lugs or projections, and in
attaching them is such a manner that the machines will not move while
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side-view of a caster applied to the leg of a sewing machine}
Figure 2 is a top view of the same. Similar letters of reference indicate
corresponding parts in both Figures.
The frame or plate A is made of cast iron or other suitable metal, by pre-
ference about two and one-half inches in length and one-fourth of an inch in
thickness. The end of the frame where the wheel or roller B is inserted is
turned upwards. The said wheel or roller has a diameter of about one and
one-fourth of an inch, and the periphery of the said wheel comes from one-
eighth to one-quarter of an inch below the plate A. A roller of this size
which is necessary in moving a heavy weight over a carpeted floor can be thus
used without raising the machine or deranging its proportions. The wheel or
roller B is made and inserted in the usual manner. The frame or plate A is
provided with lugs D at the sides which project ppwards, and are fitted one
on each side of the leg of the machine, or a hole may be drilled into the
bottom of the said leg, and a single lug or a pair of lugs may be used, as
shewn at E. The object of these lugs is to prevent the caster from turning
and at the same time to form an easy and simple attachment to an iron foot.
Two methods of attachment are shewn in the Drawings. The one which
suits the form of the foot more generally used is to attach the plate A of the
caster to the said foot by means of the lugs D or by the projection or pin E, the
screw B¹ bringing the caster wheel on the inside. The screw B¹ is put through
the projection or foot of the leg, and is tapped into the plate A, and being at
the outer side it has the advantage of the leverage to ensure its completo
action. The frame or plate A is prevented turning aside by the lugs D when
placed at the side, or by the projection or pin E when placed centrally. In

page_text: the other method of attachment the pointed lugs F are employed. The said
lugs are cast on the curved portion of the frame or plate A, and are fitted into
corresponding notches, filed or otherwise formed in the leg to receive them.
The screw C is tapped through the flange A¹ of the frame or plate A,
and draws the lugs F properly into the spaces made for them. When the
foot is enlarged around the leg or at the sides the lugs are made to fit the
enlargement on one side and an elevation on the opposite side. A universal
caster might also be easily attached to the machine foot by simply drilling a
hole in the bottom of the said foot, but this has been found not to answer, as
the machine when mounted on universal casters will move when in operation
which is not desirable. By the use of these casters the machine can be moved
over a carpeted floor to any part of the room without injuring the carpet.
The said machine will not move when in use, as the pressure required to put
it in operation is against the side. The height of the machine is not increased
as would be the case if ordinary casters were employed. The lugs or other
devices described prevent the turning of the caster from its proper position,
and the use of the said lugs allows the casters to be permanently attached to
iron feet by a single screw.
Having thus fully described the said Invention as communicated to me by
my foreign correspondent, and shown how the same may be conveniently and
advantageously carried into practise, I claim the combination of the frame
or plate A, the wheel or roller B, with the leg or stand of a sewing machine,
the said frame wheel and leg being secured together by means of screws and
lugs, substantially as described.
In witness whereof, I, the said George Haseltine, have hereunto set
my hand and seal, this Twentieth day of November, in the year of
our Lord One thousand eight hundred and sixty-six.
Witness,
HENRY WILLIAM GILBY,
