(amongst other) that we, the said Edmund Hartley, George Little, and
John Hinchcliffe, by an instrument in writing under our hands and seals,
or under the hand and seal of one of us, 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 George Little, do hereby declare the
nature of our 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 and accompanying Drawings (that is to say):-
Our Invention consists in submitting spindles, shafts, or rods to the action of
two rollers, which extend in the direction of the length of the said articles, in
combination with a stop-piece, against which the articles are caused to abut.
This method of rolling or straightening is applicable to the manufacture of
spindles of preparing and spinning machinery, or to other purposes in which
cylindrical or tapered rods or shafts are required, and is intended to avoid (in

page_text: some cases) the necessity for turning. In operating upon tapered articles we
use rollers of a conical form.
The Figures on Sheet 1 of the accompanying Drawings represent the
machinery we employ for rolling or straightening cylindrical articles.
Fig. 1 is a side elevation; Fig. 2, a section taken in the line A, B, of
Fig. 1, and looking towards the left hand; Fig. 3 is a plan view of Fig. 2,
taken in section through the lower roller, and Fig. 4 is a detached view of the
rollers and stop-piece connected therewith. The framework is at 1, carrying
bearings, within which is mounted a roller 2. Above this is another roller 3,
mounted in bearings 4, which are capable of being moved upwards or down-
ward within guides formed by the framework; to these bearings are jointed
connecting rods 5, their upper ends being adapted to excentrics 6 mounted
upon a cross shaft 7, upon which a lever 8 is fixed; this lever carries studs 9
situate within slots formed in a bracket 10, and by which the extent of motion
of the said lever is determined. Upon the framework I are formed guides 12,
upon which is mounted a sliding piece 13, carrying a pinion 14, taking into a
rack 15, and upon the said pinion therefore being turned by means of the
handle 16, the sliding piece 13 may be caused to travel upon its guides. At 17
is a weighted cord or chain passing over a guide pulley 18, by which the
sliding piece 13 is constantly drawn, and at 19 is a clamp mounted in the
At 20 is a plate
sliding piece 13, so as to be capable of turning therein.
of metal extending the width of the rollers, and fixed upon a piece 21, which
is mounted after the manner of a slide rest, and is capable of being adjusted
to or fro, so as to regulate the position of the plate 20 by turning the screw 22.
At 23 is the main driving pulley fixed upon a shaft 24, which shaft at its other
end carries a pinion 25, taking into a wheel. 26 carried by a cross shaft 27.
On the other end of this shaft is a pinion 28, taking into two carriers 29 in
gear with pinions 30, 31, fixed upon the axes of the rollers 2, 3; these rollers,
as shewn in the Drawing, as constructed by placing rings of steel upon spindles,
but this is merely a matter of construction; in order to save the expense of
constructing the said rollers entirely of steel, some of the rings in the upper
roller are omitted, but they may be continuous, so as to form a cylinder of
one diameter like the lower roller, if desired. When a bar is to be rolled or
straightened the attendant elevates the lever S, and by thus turning the ex-
centrics 6 causes the roller 3 to be raised from the lower roller 2.
The article to be operated upon is placed in the clamp 19, and secured
therein by the screws, after which it is introduced between the rollers 2, 3, by
turning the handle 16, so as to cause the sliding piece 13 to travel upon its
guides. The lever S is then pressed downward, so as to cause the roller 3 to

page_text: be forced to any required amount upon the article to be rolled or straightened;
motive power being now applied through the pulley 23, the rollers 2, 3, will
be caused to revolve in opposite directions, rolling or straightening the article
between them, during which operation it will be drawn forward by the weighted
cord or chain 17, and allowed to turn upon its axis by means of the clamp 19
being at liberty to revolve within the sliding piece 13. The rollers are geared
according to the Drawing to work at the same speeds, but the position of the
stop-piece 20 is so regulated as to allow the article under operation to be a
short distance beyond the centre line, and it is therefore kept against the said
stop-piece. We may here state, that we have found rollers with threads chased
upon them to answer.
Sheet 2 of the accompanying Drawings represents the machinery we employ
for rolling or straightening articles of a tapered form, and is peculiarly applicable
to the treatment of spindles of spinning machinery; Fig. 5 is an elevation in
section; Fig. 6 a plan view in section; and Fig. 7, an end view of Fig. 5,
also partly in section. The framework is at 30, within which are bearings 31
carrying a conical roller 32. Above this is another conical roller 33, mounted
in bearings 34, which are carried by a separate frame 35, mounted upon a
hinged joint 36. The other end of this separate frame 35 is situate with a
slot formed in a standard 36, and is connected to an excentric 37 mounted
upon a shaft 38. The end of this shaft is provided with a square for the
adaptation of a hand lever; and the shaft 38 being by these means turned, the
excentric 37 will elevate or depress the roller 35. At 54 is a plate extending
the width of the rollers, and mounted upon a part constructed as a slide rest,
so that the said plate may be adjusted in position; as described in reference to
Sheet 1. The main driving pulley is at 39 mounted upon a shaft 40, which
carries a pinion 41 taking into a wheel 42 upon a cross shaft 43. The other
end of this shaft is provided with a pinion 44, taking into two carriers 45, 46,
which are in gear with pinions 47,48, upon the axes of the two rollers. When
an article of a tapered form is to be rolled or straightened, the attendant by
turning the shaft 38, raises the upper roller 33, and the said article is then
introduced, as shewn at 49, the excentric 37 being turned so as to cause any
desired pressure thereon, and motive power being then applied through the
pulley 39, the rolling or straightening will be effected.
It will be perceived that in the Drawing a portion only of the spindle can
be rolled, such only being required in the example given, but the rollers may
of course be of any width.
In the above description we have supposed that articles of one degree of
taper only are operated upon, but we provide means whereby the rollers may

page_text: be caused to accommodate themselves to articles of different degrees of taper.
For this purpose the separate frame 35 is provided at each end with studs
50, 51, mounted in sockets 52, 53, the former of these being the part which
slides in the standard 36, by these means therefore the roller 33 is at liberty to
swivel to a certain extent, and thus adapt itself to various degrees of taper.
In the plan view of the machine the ends of the rollers and certain other
parts would of course be seen in an elliptical form, but for the sake of
simplicity we have shewn them as though their axes were horizontal.
Having thus described and ascertained the nature of our said Iuvention and
the manner in which the same is to be performed, we desire it to be understood
that we do not limit ourselves to the precise arrangement of parts shewn and
described; but claim as secured to us under the above in part recited Letters
Patent, and for the purposes above set forth, the use of two rollers, the axes
whereof extend in the direction of the length of the article to be operated
upon, in combination with a stop-piece, as illustrated at 20 and 54.
In witness whereof, I, the said George Little, have hereunto set my hand
and seal, this Thirtieth day of October, in the year of our Lord One
thousand eight hundred and sixty-two.
GEORGE LITTLE. (L.S.)
