Year: 1861

page_text: LETTERS PATENT to William Ryder, of Bolton-le-Moors, in the County
of Lancaster, Roller and Spindle Maker, and Thomas Ryder, of the
same Place, Foreman, for the Invention of."IMPROVEMENTS IN MACHINERY
FOR FLUTING ROLLERS."
PROVISIONAL SPÉCIFICATION left by the said William Ryder and
Thomas Ryder at the Office of the Commissioners of Patents, with their
Petition, on the 28th October 1861.
We, WILLIAM RYDER, of Bolton-le-Moors, in the County of Lancaster,
Roller and Spindle Maker, and THOMAS RYDER, of the same Place, Foreman,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY FOR FLUTING ROLLERS," to be as follows:-
The object of the first part of this Invention is to regulate the depth of cut
of all the cutters simultaneously, instead of regulating each cutter indepen-
dently of the others, as now customary. In performing our Invention we
support the bar to which the tool boxes are connected in eccentric bushes,
each of which is furnished with a toothed wheel driven by pinions fixed to a
side shaft. To this shaft is attached a hand wheel, with divisions on its
circumference; by turning this hand wheel partly round, the eccentric bushes
acting on the bar cause all the cutters to rise or descend simultaneously,
thereby regulating the depth of cut of the cutters. The details may be con-

page_text: siderably varied, and each cutter can be regulated independently of the others
as usual.
The second part of this Invention consists in an improved combination of
machinery for cutting diagonal flutes in or on rollers. In order to accomplish
this, a slight lateral motion is given to the cutters by means of a template
fixed to the carriage acting on a lever, which communicates the requisite
to-and-fro motion to the boxes or slides supporting the cutters; by this means
the rollers remain stationery while the cut is given, and they are turned
partly round after each cut in the usual manner.
The above improvements may be used in combination with each other or
separately.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Ryder and Thomas Ryder in the Great Seal Patent
Office on the 28th April 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
RYDER, of Bolton-le-Moors, in the County of Lancaster, Roller and. Spindle
Maker, and TномMAS RYDER, of the same Place, Foreman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of October, 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 us,
the said William Ryder and Thomas Ryder, Her special license, that we, the
said William Ryder and Thomas Ryder, our executors, administrators, and
assigns, or such others as we, the said William Ryder and Thomas Ryder,
our 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 MACHINERY FOR FLUTING
ROLLERS," upon the condition (amongst others) that we, the said William
Ryder and Thomas Ryder, our executors or administrators, by an instrument
in writing under our, or their, or one of our or 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

page_text: NOW KNOW YE, that we, the said William Ryder and Thomas Ryder,
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):-
The object of the first part of this Invention is to regulate the depth of cut of
all the cutters simultaneously, instead of regulating each cutter independently of
the others, as now customary. In performing our Invention we support the
bar to which the tool boxes are connected in eccentric bushes, each of which
is furnished with a toothed wheel driven by pinions fixed to a side shaft.
To this shaft is attached a hand wheel with divisions on its circumference; by
turning this hand wheel partly round, the eccentric bushes acting on the bar
cause all the cutters to rise or descend simultaneously, thereby regulating the
depth of cut of the cutters. The details may be considerably varied, and
each cutter can be regulated independently of the others as usual.
The second part of this Invention consists in an improved combination of
machinery for cutting diagonal flutes in or on rollers. In order to accomplish
this, a slight lateral motion is given to the cutters by means of a template
fixed to the carriage, acting on a lever which communicates the requisite
to-and-fro motion to the boxes or slides supporting the cutters; by this means
the rollers remain stationary while the cut is given, and they are turned partly
round after each cut in the usual manner.
The above improvements may be used in combination with each other or
.separately.
And in order that our Invention may be fully understood and readily carried
into effect, we will proceed to describe the accompanying Sheet of Drawings,
reference being had to the figures and letters marked thereon.
Fig. 1 is an elevation of a machine for fluting rollers to which our improve-
ments are applied; Fig. 2 is an end view, and Fig. 3, a plan of part of the
same.
a is the framing of the machine; b, the carriage or table on which the
rollers to be fluted are secured; c, the bar to which the tool boxes d are
connected. These parts, and the machinery for moving the carriage or table
to and fro are made in any approved manner, but the bar c, instead of being
supported in the bearings e, pass through the eccentric bushes f, see Fig. 4, and
these bushes are supported in the bearings e. To each bush f is cast or fixed
a spur wheel g, and the pinions h fixed on the cross shaft i gear in the
wheels 9. The hand wheel j, fixed to one end of the shaft i, has divisions on
its circumference, and a pointer k is fixed to one of the bearings e; by
turning this hand wheel partly round, the pinions h turn the wheels 9 and

page_text: eccentric bushes ƒ partly round, thereby raising or lowering all the cutting
tools simultaneously, according to the direction in which the hand wheel is
turned. The cutting tools being connected to the tool boxes d in the usual
manner can also be adjusted independently of each other.
Our improved combination of machinery for cutting diagonal flutes in or
on rollers consists of the following parts:-To, one end of the bar c, to which
the cutting tools are connected in the usual manner, are fixed the two set
washers c¹ and c, between which the end of the lever enters. This lever is
supported on the fulcrum stud.m, and to it is fixed the arm, at the extremity
of which is an antifriction roller, which is held in contact with the template n
by the spring o. The template is made, by preference, of a round bar of
steel, on which are turned conical surfaces corresponding in number to the
number of bosses on the fluted roller to be. cut. The peculiar construction of
the template may however be considerably varied; it is supported in two
bearings fitting in a groove in the table b, and its length must also vary
according to the length of the fluted rollers under operation. The bar c must
have a little play. between. the bearings or between the wheels g, to allow
for the lateral motion given to the cutters for producing the diagonal flutes;
when the lateral motion is not required to be given, the space allowed for
play is filled up by a washer at each end of the bar. The mode of operation
is as follows: When the carriage or table 6 is moving towards the cutters,
and the flutes are being cut in the rollers fixed on the table, the bar c is
moved to and fro in the direction of its length by the conical surfaces of the
template n acting on the antifriction bowl in the arm l' of the level 1, the
upper end of the lever being slightly rounded where it enters between
the two set washers c¹ and c³ on the bar c, to impart a uniform motion to the
bar c. When the larger diameters of the cones on the template n act on
the lever the tension of the spring o has to be overcome, but when the anti-
friction bowl is acting on the smaller diameter of the cones on the template,
the spring o, acting on the lever l, moves the bar. c and the cutting tools in the
contrary.direction, thus alternately cutting.diagonal flutes in or on the rollers.
The lever. fixed to the end of the bar c is for the purpose of elevating the
cutters above the rollers during the return of the carriage, but forms no part
of our present Invention. The rollers are turned partly round after each cut
in the ordinary manner.
Having thus stated the nature of our Invention, and described the manner
of performing the same, we wish to observe that our improvements may be
used in combination with each other, or separately; and we declare that we
claim,―

page_text: First, the improved combination of machinery for regulating simultaneously
the depth of cut of all the cutters employed in machines for fluting rollers, as
shewn and described.
Secondly, the combination of machinery shewn and described for cutting
diagonal flutes in or on rollers, or any modification of machinery for producing
the same result, by moving the cutting tools laterally while the rollers are
moving in the direction of their length.
In witness whereof, we, the said William Ryder and Thomas Ryder,
have hereunto set our hands and seals, this Twenty-sixth day of
April, in the year of our Lord One thousand eight hundred and
sixty-two.
