Year: 1861

page_text: LETTERS PATENT to William Kempe, of Holbeck Mills, Leeds, for the
:
Invention of "IMPROVEMENTS IN SCRAYS OR TABLES APPLICABLE TO GIG MILLS,
BRUSHING MILLS, AND OTHER LIKE MACHINERY."
Sealed the 17th June 1862, and dated the 21st December 1861.
PROVISIONAL SPECIFICATION left by the said William Kempe at the
Office of the Commissioners of Patents, with his Petition, on the 21st
'December 1861.
I, WILLIAM KEMPE, of Holbeck Mills, Leeds, do hereby declare the nature
of the Invention for "IMPROVEMENTS IN SCRAYS OR TABLES APPLICABLE TO GIG
MILLS, BRUSHING MILLS, AND OTHER LIKE MACHINERY," to be as follows:-
This Invention has for its object improvements in the scrays or tables which
are attached to gig mills, brushing mills, and other similar machines, so that
where the cloth or fabric has to pass more than once through the machine it
may be supplied in the exact quantity and position required by such mill or
machine without any undue pull or strain upon the fabric, reducing the
amount of attendance required, and rendering the machine to a great extent
self-acting.
These improvements I accomplish in the following manner:-In place of
the flat or inclined table or scray or the trough scray of the gig mill, brushing

page_text: mill, or other similar machine, I fix parallel to each other two frames having
the form of an inverted semicircle or curve, but having projecting feet to fix
them firmly to the floor. These frames are of cast iron and fastened together
by any suitable and convenient arrangement. Through the top of each limb
of the semicircular or curved framing on one side I pass a shaft at right
angles to the framing, continuing such shaft through the top of each limb of
the semicircular or curved fratning on the other side. It will thus be seen
that there are two shafts extending across the machine at the top of each limb
of the semicircular or curved framing, parallel to each other, but at right angles
to the two curved frames which form the sides of the machine. At each end
of these two shafts, but within the framing, I fix a pulley, known as a "chain
wheel," or pulley having projecting knobs cast on its periphery for gearing into
the square links of a suitable chain (or the chain and chain wheels may be
otherwise formed); over these pullies I pass two endless chains parallel to
the two semicircular or curved frames, these chains are put on sufficiently
"slack" that they may rest upon the semicircular or curved sweep of the
frame through its entire curve. To these chains I fasten, by screws or any
other suitable way, a series of laths across the machine, that is to say, at right
angles to the chain, one end of each lath being fastened to a link of one chain,
and the other end of the lath being fastened to a corresponding link of the
other chain. This part of the machine therefore becomes a continuous plat-
form free to move as the chain pullies are moved. The two shafts upon which
the chain wheels or pullies are fixed are coupled together by a system of bevel
wheels and shafts or any other convenient arrangement for obtaining the
simultaneous and uniform motion of these two shafts, having motion com-
municated to them by the driving shaft, placed in any convenient position. It
will be evident from the two shafts working uniformly and simultaneously that
one part of the 'endless chains with the laths affixed, forming the scray, will
descend one limb of the semicircular or curved sweep in the same time and
quantity as another part of the scray is ascending the other limb, so that the
scray will always retain its semicircular or curved form. The cloth or fabric
being delivered from the gig mill or other similar machine in plaits or folds at
the top of one limb of the semicircle or curve travels down with the scray and
is carried up the other limb of the semicircle or curve ready for delivery
agáin to the gig mill or other similar machine. It will thus be seen that the
cloth in travelling round the semicircle or curve changes its position, that
which was underneath at one limb of the curve being uppermost at the other.
It is also preferred that the 'curve should be a semicircle, but that is not
absolutely necessary, neither do I confine myself to the application of endless

page_text: chains, as the same result may be obtained by means of straps or belts of any
suitable material with drums or pulleys suitably formed to insure accuracy of
movement of the two straps or belts.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Kempe in the Great Seal Patent Office on the
21st June 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
KEMPE, of Holbeck Mills, Leeds, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of December, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Kempe, Her special licence that I, the said William Kempe,
my executors, administrators, and assigns, or such others as I, the said
William Kempe, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 "IMPROVE-
MENTS IN SCRAYS OR TABLES APPLICABLE TO GIG MILLS, BRUSHING MILLS, AND OTHER
LIKE MACHINERY," upon the condition (amongst others) that I, the said William
Kempe, 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 Letters Patent.
NOW KNOW YE, that I, the said William Kempe, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
This Invention has for its object improvements in the scrays or tables which
are attached to gig mills, brushing mills, and other similar machines, so that
where the cloth or fabric has to pass more than once through the machine it
may be supplied in the exact quantity and position required by such mill or
machine without any undue pull or strain upon the fabric, reducing the

page_text: amount of attendance required, and rendering the machine to a great extent
self-acting.
These improvements I accomplish in the following manner:-In place of
the flat or inclined table or scray, or the trough scray of the gig mill, brushing
mill, or other similar machine, I fix parallel to each other two frames having
the form of an inverted semicircle or curve, but having projecting feet to fix
them firmly to the floor. These frames are of cast iron and fastened together
by any suitable and convenient arrangement. Through the top of each limb
of the semicircular or curved framing on one side I pass a shaft at right
angles to the framing, continuing such shaft through the top of each limb of
the semicircular or curved framing on the other side. It will thus be seen
that there are two shafts extending across the machine at the top of each limb
of the semicircular or curved framing parallel to each other, but at right angles
to the two curved frames which form the sides of the machine. At each end
"chain
of these two shafts, but within the framing, I fix a pulley, known as a
wheel," or pulley having projecting knobs cast on its periphery for gearing into
the square links of a suitable chain (or the chain and chain wheels may be
otherwise formed). Over these pullies I pass two endless chains parallel to
the two semicircular or curved frames; these chains are put on sufficiently
"slack" that they may rest upon the semicircular or curved sweep of the
frame through its entire curve. To these chains I fasten, by screws or in any
other suitable way, a series of laths across the machine, that is to say, at right
angles to the chain, one end of each lath being fastened to a link of one chain,
and the other end of the lath being fastened to a corresponding link of the
other chain. This part of the machine therefore becomes a continuous plat-
form free to move as the chain pullies are moved. The two shafts upon which
the chain wheels or pullies are fixed are coupled together by a system of bevel
wheels and shafts or any other convenient arrangement for obtaining the
simultaneous and uniform motion of these two shafts, having motion com-
municated to them by a driving shaft, placed in any convenient position. It
will be evident from the two shafts working uniformly and simultaneously that
one part of the endless chains with the laths affixed, forming the scray, will
descend one limb of the semicircular or curved sweep in the same time and
quantity as another part of the scray is ascending the other limb, so that the
scray will always retain its semicircular or curved form. The cloth or fabric
being delivered from the gig mill or other similar machine in plaits or folds at
the top of one limb of the semicircle or curve travels down with the scray and
is carried up the other limb of the semicircle or curve ready for delivery again
to the gig mill or other similar machine. It will thus be seen that the cloth

page_text: in travelling round the semicircle or curve changes its position, that which
was underneath at one limb of the curve being uppermost at the other. It is
also preferred that the curve should be a semicircle, but that is not absolutely
necessary, neither do I confine myself to the application of endless chains, as
the same result may be obtained by means of straps or belts of any suitable
material with drums or pulleys suitably formed to insure accuracy of movement
of the two straps or belts.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that I make no claim to the
mechanical parts separately; but what I claim is, the combination of mechanism
herein described, whereby the folds of cloth received on to a moveable scray
are caused, by the form and motion of the scray, to be turned over before
passing off the scray, and in such manner that that which was undermost
when received on to the scray is uppermost when about to pass off the
scray.
In witness whereof, I, the said William Kempe, have hereunto set my
hand and seal, this Seventeenth day of June, in the year of our Lord
One thousand eight hundred and sixty-two.
WILL". KEMPE. (L.S.)
