Year: 1858

page_text: LETTERS PATENT to Asa Lees, of the Soho Iron Works, Oldham, in the
County of Lancaster, Machine Maker, and David Schofield, of the same
Place, Manager, for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION.
OP CARRIAGES FOR CERTAIN MACHINDS USED IN SPINNING AND DAR"
PROVISIONAL SPECIFICATION left by the said Asa Lees and David
Schofield at the Office of the Commissioners of Patents, with their
Petition, on the 10th April 1858.
We, ASA LEES, of the Soho Iron Works, Oldham, in the County of
Lancaster, Machine Maker, and DAVID SCHOFIELD, of the same Place,
Manager, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN THE CONSTRUCTION OF CARRIAGES FOR CERTAIN MACHINES USED IN
SPINNING AND DOUBLING," to be as follows:-
In constructing the carriages of mules and doublers, it has heretofore been
customary to make the framework of wood, and to attach thereto the requisite
brackets and bearings for supporting the tin drum, the faller shafts, and the
footstep, and bolster rails; now, our Invention consists in constructing such
carriages in the following manner :-Light cast-iron frames connected by
diagonal stay rods are placed at suitable distances apart; to these frames are
fixed the bearings for the tin drum and for the faller shafts. The sideboards
with the footstep and bolster rails, and the topboard, are secured to these
frames, and the back boards fit within grooves cast in the frames; the front
boards may be held by flanges cast to the frames or supported in the usual
manner.
The object of this Invention is to economise time in. constructing carriages,.

page_text: as the fitting together and glueing of the woodwork, hitherto necessary, is
dispensed with. Carriages constructed according to our improvements are
also more durable and rigid than those made in the usual manner.
Another part of our Invention consists in casting the footsteps of spindles
forming part of the said carriages with a flat-bottomed recess. These foot-
steps are then fixed in the footstep rail, and the hole for the spindle to work
in is then drilled; by thus casting the footsteps a saving in metal and in
planing or filing up is effected.
Our Invention also consists in making the bolster or collar of the spindle
with a bead or rib round three sides, the object of which is to prevent the oil
running on the bolster rail, and to economise labour in planing or filing up.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Asa Lees and David Schofield in the Great Seal Patent
Office on the 9th October 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ASA
LEES, of the Soho Iron Works, Oldham, in the County of Lancaster,
Machine Maker, and DAVID SCHOFIELD, of the same Place, Manager, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of April, in the year of our Lord One
thousand eight hundred and fifty-eight, in the twenty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Asa Lees and David Schofield, Her special licence that we, the 'said Asa
Lees and David Schofield, our executors, administrators, and assigns, or such
others as we, the said Asa Lees and David Schofield, our executors, admi-
nistrators, 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 CARRIAGES FOR
CERTAIN MACHINES USED IN SPINNING AND DOUBLING," upon the condition
(amongst others) that we, the said Asa Lees and David Schofield, our
executors or administrators, by an instrument in writing under our, or their,
or one of our or their hands and seals, should praticularly 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

page_text: Patent Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that we, the said Asa Lees and David Schofield, do
hereby declare the nature of our said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in
and by the following statement (that is to say):-
In constructing the carriages of mules and doublers it has heretofore been
customary to make the framework of wood, and to attach thereto the requisito
brackets and bearings for supporting the tin drum, the faller shafts, and the
footstep and bolster rails; now, our Invention consists in constructing such
carriages in the following manner:-Light cast-iron frames connected by
diagonal stay rods are placed at suitable distances apart; to these frames
are fixed the bearings for the tin drum and for the faller shafts, the side
boards with the footstep and bolster rails and the top board are secured to
these frames, and the back boards fit within grooves cast in the frames; the
front boards may be held by flanges cast to the frames or supported in the
usual manner.
Another part of our Invention consists in casting the footsteps of spindles
forming part of the said carriages with a flat bottomed recess; these footsteps-
are first fixed in the footstep rail, and then the hole for the spindle to work
in is drilled.
Our Invention also consists in making the bolster or collar of the spindle
with a bead or rib round three sides of the top flange.
And in order that our Invention may be fully understood and readily
carried into effect, we will proceed to describe the means pursued by us,
reference being had to the accompanying Sheet of Drawings, and to the
figures and letters marked thereon.
Fig. 1 is a transverse section of a carriage for a mule or doubler constructed
according to our improvements; Fig. 2 is a plan view on a reduced scale of
part of our carriage; Figs. 3 and 4 are detached views of our improved
bolster or collar for the spindles of mules or doublers; and Fig. 5 is a section
of our improved footsteps for spindles. In Figs. 1 and 2, a, a, are light cast-
iron frames, which are placed at suitable distances apart, and connected
together by the diagonal stay rods b, b; to these frames are bolted the bear-
ings c for the tin drum d, by which the spindles e are driven in the usual
manner, and the bearings f for the faller and counterfaller shafts g and h.
To the frames a, a, are also bolted the side boards i and j, the top board k,
the bolster rail, and footstep rail m; the back board n fits between grooves
cast to the frames a, and the front boards o, o, may either fit between grooves

page_text: cast to the frames a, or the upper one may be fixed to the bolster rail l, and
the lower one hinged to the foot step rail, as shewn in the Drawing.
By thus constructing carriages a considerable saving in time and labour is
effected, as the fitting together and the glueing of the woodwork hitherto
necessary is dispensed with. Carriages thus constructed are also more durable
and rigid, and are more conveniently packed for transport, than those made in
the usual manner.
The collar or bolster p shewn in section in Fig. 3, and in plan in Fig. 4, is
cast with a bead or rib round the two sides and at one end of the top flange,
the object of which is to prevent the oil or other lubricating material running
on to the bolster rail, and to economise labour in planing or filing up, as,
according to our improvements, it is only necessary to plane or file up the top
of the bead instead of the whole surface of the top flange. The footsteps q,
shewn in Fig. 5, are cast with a flat-bottomed recess; these footsteps, after
being turned up, are fixed into the footstep rail m, and then the hole in which
the spindle works is bored out; the object of the flat-bottomed recess is to
allow the boring tool to commence boring the hole, so that it will coincide
exactly with the hole in the bolster or collar p; a saving in metal and in labour
is also effected by casting footsteps with a flat-bottomed recess, as described.
Having thus fully described the nature of our Invention, and the manner
of performing the same, we wish it to be understood that we do not limit
ourselves to the precise details herein set forth; but what we do claim is,-
First, the improved construction of carriages for certain machines used in
spinning and doubling, as shewn and described, and particularly the cast-iron
frames marked a, a.
Secondly, casting the bolsters or collars of spindles with a bead for tho
purposes described.
And, lastly, casting the footsteps of spindles with a flat-bottomed recess, as
described.
In witness whereof, we, the said Asa Lees and David Schofield, have
hereunto set our hands and seals, this Eighth day of October, in
the year of our Lord One thousand eight hundred and fifty-eight.
