and Son, Patent Agents, 123, Chancery Lane, London, for the In-
vention of "IMPROVED MODES OF APPLYING CASTORS TO SEWING MACHINES,

Sealed the 10th February 1874, and dated the 13th August 1873.
PROVISIONAL SPECIFICATION left by the said Edward Thomas Hughes
at the Office of the Commissioners of Patents, with his Petition,
on the 18th. August 1878.
I, EDWARD THOMAS HUGHES, of the Firm of Hughes & Son,
Patent Agents, 123, Chancery Lane, London, do hereby declare the
nature of the said Invention for "IMPROVED MODES OF APPLYING CASTORS TO
SEWING MACHINES, FURNITURE, AND OTHER ARTICLES,” a communication to me
from abroad by Joseph B. Sargent, of New Haven, Connecticut, United
States of America, to be as follows:
This Invention consists in certain improvements upon one of the parts

page_text: of an Invention for which Letters Patent were granted to me, bearing
date the Twenty-second day of June, One thousand eight hundred and
seventy-one, No. 1640, and entitled "Improvements in Castors for
Furniture, Sewing Machines, and for like Purposes." In the Specification
of that Invention it is stated that this Invention relates to an improve-
ment in the construction and application of furniture castors especially
designed for sewing machines, but applicable to other articles of
furniture, and after describing five parts of the Invention it states, that
the sixth part relates to an improvement in castors for sewing machine
tables, to be operated in such manner that when desired to move the
machine the castor wheels may be made to take the bearing or weight of
the machine, and when at rest or in position the wheels are relieved
from the weight that the machine may stand firmly on the floor.
The present Invention relates to this sixth part, and consists in
improved mechanical arrangements for enabling the machine to rest
upon a set of four swivel castors, so that it can be easily removed from
one position to another, and also for enabling the feet of the standards
to rest on the floor when the machine is to stand firm in any required
position.
:
To the lower ends of the standards or framework carrying the table
are clamped metal blocks or brackets having holes, to which are fitted
pins fixed to cross bars mounted at their ends with swivel castors, and
having in the middle bearings or bosses carrying a horizontal shaft from
one end or side of the machine to the other. To this shaft is fixed a
treadle, lever, and two cams or eccentrics, in contact with shoulders on
the clamped blocks, and when the treadle is pressed by the foot the
standards and table are raised from the floor, the entire machine resting
securely on the four swivel castors, and when the treadle is raised by the
toe the machine again drops upon the floor and stands firm for sewing;
and it is evident that this improved arrangement can be applied to other
machines and articles.

successors, give and grant unto me, the said Edward Thomas Hughes,
Her special licence that I, the said Edward Thomas Hughes, my
executors, administrators, and assigns, or such others as I, the said
Edward Thomas Hughes, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to timë
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 Island's,
and Isle of Man, an Invention for "IMPROVED MODES OF APPLYING CASTORS
TO SEWING MACHINES, FURNITURE, AND OTHER ARTICLES,” a communication to
me from abroad by Joseph B. Sargent, of New Haven, Connectiont,
United States of America, upon the condition (amongst others) that I,
the said Edward Thomas Hughes, 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 Eetters
Patent.
NOW KNOW YE, that I, thế sâid Edward Thomas Huglies; do hereby
declare-the-nature of the said Invention, and in what manner the summe
is to be performed, to be particularly described and ascertained in áñď
by the following statement, reference being had to the accompanying
Sheet of Drawings, and to the figures and letter's marked thereon, that
is to say:-
This Invention consists in certain improvements upon one of the parts

page_text: date the Twenty-second day of June, One thousand eight hundred and
seventy-one, No. 1640, and entitled "Improvements in Castors for
Furniture, Sewing Machines, and for like Purposes." In the Speci-
fication of that Invention it is stated, that the Invention relates to an
improvement in the construction and application of furniture castors, 5
especially designed for sewing machines, but applicable to other articles
of furniture, and after describing five parts of the Invention it states,
that the sixth part relates to an improvement in castors for sewing
machine tables, to be operated in such manner that when desired to
move the machine the castor wheels may be made to take the bearing or 1
weight of the machine, and when at rest or in position the wheels are
relieved from the weight that the machine may stand firmly on the
floor.
The present Invention relates to this sixth part, and consists in
improved mechanical arrangements. for enabling the machine to rest 1
upon a set of four swivel castors, so that it can be easily removed from
one position to another, and also for enabling the feet of the standards
to rest on the floor when the machine is to stand firm in any desired
position.
On the accompanying Sheet of Drawings Fig. 1 is a perspective view
of the feet and part of the standards which support the table of a sewing
machine, provided with the improved arrangement and apparatus for
lowering and raising the castors.
Fig. 2, a perspective view of the apparatus detached; and Figs. 3, 4, 5,
and 6, are enlarged views of some of the parts.
To the lower ends of the standards or framework carrying the table
are clamped metal blocks or brackets a having holes or sockets 6, Fig. 3,
to which are fitted pins c fixed to cross bars d mounted at their ends
with swivel castors e, and having in the middle bearings or bosses f
carrying a horizontal shaft g which extends from one end or side of the
machine to the other. To this shaft is fixed a treadle h and two cams
or excentrics i, in contact with shoulders ; on the clamped blocks, and
when the treadle is pressed down by the foot so as to turn up the cams i
in contact with the shoulders; the standards and table are raised from
the floor, the entire machine resting on the four swivel castors, so that it
can be easily moved from place to place, and when the treadle is raised
and the cams turned away from the shoulders the machine again drops

page_text: upon the floor and stands firm for sewing; and it is evident that this
improved arrangement can be applied to other machines and articles.
Having now described the nature and particulars of the said Invention
and the manner in which the same is to be performed, I desire it to be
understood that for sewing machines, furniture, and other articles I
claim, the application and employment of blocks or brackets having
shoulders in contact with cams or eccentrics on a shaft to which a
treadle is fixed for the purpose of enabling the machine, piece of
furniture, or other article to be easily moved from place to place, and
also to rest firmly on the floor when required, as such improvements
are herein described and illustrated on the accompanying Drawings.
In witness whereof, I, the said Edward Thomas Hughes, have
hereunto set my hand and seal, this Twelfth day of February, in
the year of our Lord One thousand eight hundred and seventy-
four.
