Year: 1878

page_text: LETTERS PATENT to George Bedson, of Manchester, in the County of Lancaster,
Manager of Iron Works, for the Invention of "IMPROVEMENTS IN MACHINERY
FOR ROLLING WIRE, RODS, OR BARS OF METAL."
Sealed the 7th January 1879, and dated the 9th July 1878.
PROVISIONAL SPECIFICATION left by the said George Bedson at the Office
of the Commissioners of Patents on the 9th July 1878.
GEORGE BEDSON, of Manchester, in the County of Lancaster, Manager of Iron
Works. "IMPROVEMENTS IN MACHINERY FOR ROLLING WIRE, RODS, OR BARS OF
METAL."
My Invention relates to improvements upon that machinery for which Letters
Patent were granted to me, dated 2nd July 1862, No. 1935. According to the
arrangement therein specified I used a series of rolls, placed alternately on hori-
zontal and vertical axes; but I now propose to arrange the axes on one plane only,
and to employ spiral guides in a special manner, and I also propose to construct the
rollers in a special manner.
To the axes disposed in one plane I adapt rollers, each of which is provided with
a number of grooves of the required shape to roll the metal alternately from one
section to another, and between each pair of rolls I adapt a spiral or curved guide
which turns the metal before it is presented to the next pair of rolls..
Each roller is provided with a series of grooves, and the guides are adapted so
that they can be moved from one pair of rolls to another, or the alternative of
moving the rolls to the guides may be adapted.
The width included by the series of grooves may be divided into sections, for
operating upon two or more rods or bars of metal side by side..

- the said George Bedson in the Great Seal Patent Office on the 9th January
1879.
GEORGE BEDSON, of Manchester, in the County of Lancaster, Manager of Iron
Works. "IMPROVEMENTS IN MACHINERY FOR ROLLING WIRE, RODS, OR BARS OF
METAL."
My Invention refers to that description of rolling in which the metal is operated
upon by rollers, which successively roll it from one section to another, as, for
instance, alternately from oval to diamond, or square, or other forms. For this
purpose I employ a succession of pairs of rollers, provided with grooves of the
alternate required forms, and arranged in a line one after another, their axes being
all on the same plane. The metal passes successively through this line of rollers
back, but between each pair it is turned partly around by a spiral guide.
The spiral guides are so adapted that they may be moved from one roller groove
to another, for which purpose the said rollers are provided with extra grooves to
be used when desired, as will hereafter be explained.
In the accompanying Drawing, Fig. 1 represents the machine in side view;
Fig. 2 is a plan view thereof; and Figs. 3, 4, and 5, detached views upon an
enlarged scale.
At a is the main frame to be placed upon masonry or disposed in any other
convenient manner, and upon this frame are pedestals b, which support the axes of
a series of pairs of rollers marked from c to 8 inclusive. The axes of these rollers
extend transversely, and are supported by bearings as at t.. At u is a line shaft
driven by the motive power, and carrying bevil wheels (not shewn in the Drawing)
which take into other bevil wheels mounted on the axes of the bottom rollers c, &c.,
each of the lower shafts being in this manner driven, and each pair of rollers is
geared together by toothed wheels w, shewn in the plan view only.
The pairs of rollers c, &c., are each provided with a groove x alternately, of oval,
diamond, or other sections, as may be selected, those of the last pair 8, however,
being of that section which the finished wire, rod, or bar is to assume.
Between each pair of rollers is placed a guide y, shewn particularly at Figs. 3, 4,
and 5, formed with parts z, by means of which it may be secured to a table 1,
bolted, as at 2, to the pedestals b. The guides y are provided with interior cavities
of a spiral form, as shewn by the dotted lines 3, 4, in Figs. 3 and 4, and in the
section Fig. 5, the metal under operation being shewn at A and the ends of the
said guides project within the circunferences of consecutive pairs of rollers, by
which means the metal in process of being rolled is received near the grip of the
said rollers and is passed through the spiral groove to the nip of the next pair,
being partly turned round, so that what are technically called cold edges are
presented to successive rollings. The heated metal is presented to the first pair of
rollers C, and is passed on thereby to succeeding pairs, by which means it is rolled
from one section to another and turned over by each guide y, as above mentioned,
the finished article of the required form issueing from the last pair 8.
It has been stated that the rollers are driven by bevil wheels, and these wheels
are so arranged in numbers of teeth that the rotations of the rollers gradually
increase in speed in proportion to the gradual decrease in section of the wire, rod,
or bar to be produced.
At 6. is a second series of grooves formed in the rollers and provided with con-
ducting spiral guides y*, the said grooves being alternately oval, diamond, or of
other form, as above described, and the heated metal is in like manner passed from
the one to the other, and in this arrangement two wires, rods, or bars of metal may
be rolled at the same time, each of them being partially turned over between
successive operations; but instead of the arrangement shewn the rollers may be

page_text: provided with three or more series of grooves and then as many wires, rods, or bars
of metal will be rolled at the same time.
In Fig. 1 the guides y are only partially shewn, but of course they are repcated
between each pair of rollers.
Referring now to Figs. 3 and 4, at 6x are additional grooves on the rollers,
formed to operate as those above described but not at the same time. The guides
y, y, are secured to the table 1 by bolts which pass through slots 8, and these
bolts being loosened the said guides may be slidden on the table, and then again
tightened opposite to the extra grooves 6x, the object being that when the first
pair of grooves is worn the second may be used by bringing the spiral guides
opposite them, and this arrangement may of course exist between each pair of the
rollers of a series, as at Fig. 1, and instead of the arrangement shewn more additional
grooves may be formed upon each roller to which the guides may be successively
adapted as required.
Having thus described and ascertained the nature of my said Invention, and the
manner in which the same is to be performed, I desire it to be understood that I
claim as secured to me under the above in part recited Letters Patent, and for the
purposes above set forth,-
Firstly. The use of a series of rollers with axes on the same plane, and provided
with grooves for operating on two or more wires, rods, or bars of metal at the same
time, the said wires, rods, or bars being turned over and conducted from one pair
of rollers to another by intervening spiral guides.
Secondly. The use of the additional grooves illustrated at 6×, together with the
transferable guides.

eight hundred and seventy-nine.
