We, THOMAS WILLIAM SIMPSON, of The Mount, Bottle Manufacturer, and
WILLIAM HENRY BRADSHAW, of 58, Lower Oxford Street, Mechanic, both of Castle-
ford, in the County of York, do hereby declare the nature of this invention to be as
follows:-
The object of our invention, is to construct apparatus whereby screw threads,
indentations, projections, or other forms may be imparted to the exterior of bottle
necks, the said forms being imparted speedily and in an even and regular manner.
According to our invention, we employ a pair of tongs having a mandrel for
inserting within the neck of the bottle for the purpose of holding same in a central
position. On the ends of the arms of the tongs, rollers are provided, the said rollers
being connected together by means of a train of wheels or other gearing, in such a
manner that when they are rotated they turn with similar relative movements one
with the other, and these movements are the same whether the tongs are open or
closed. The gearing may suitably be composed of five or other uneven number of
toothed wheels, two of which are mounted on the rollers, the others being carried
on a folding frame situated between the arms of the tongs, and the interior of the
arms of the tongs are provided with stop surfaces which abut together or against
the central mandrel, so as to gauge the limit of contraction of the arms.
outer surface of the rollers, recesses are formed of the shape of the screw threads,
projections, or indentations which are required to be made on the exterior of the
bottle neck; and on the apparatus being applied to the bottle neck, the tongs are
closed thereby bringing the rollers against the surface of the neck.
On the
The rollers rotate by reason of their contact with the exterior of the bottle neck,
and as the said rollers are geared together, their movements are relatively the same
one to the other, thereby insuring the indentures of the rollers timing in with one
another, and preventing one roller cutting or pressing grooves in different positions
to the other roller.

We, THOMAS WILLIAM SIMPSON, of The Mount, Bottle Manufacturer, and
WILLIAM HENRY BRADSHAW, of Lower Oxford Street, Mechanic, both of Castle-
ford, in the County of York, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
The object of our invention, is to construct apparatus whereby screw threads,
indentations, projections, or other forms, may be imparted to the exterior of bottle
necks, the said forms being made speedily and in an even and regular manner.
In order that our invention may be clearly understood, we will proceed to describe
same with reference to the accompanying drawing, in which similar letters refer
to like parts in all the figures.
Figure 1 is an elevation of apparatus constructed according to our invention,
and Figures 2 and 3 are plans of same. Figure 4 is a plan view shewing a
modification.
According to our invention, we employ a pair of tongs consisting of the ordinary
central spindle A, side springs B, B and mandrel C, which latter is passed within
the neck of the bottle for the purpose of holding same in a central position. On
the ends of the arms B, B of the tongs, rollers D, D are provided, the said
rollers D, D being connected together by means of a train of wheels, preferably
composed of five toothed wheels E, E and F, F, F. The two wheels E, E are
mounted on spindles D¹, D¹ and are connected to the rollers D, D; whilst the other
three wheels F, F, F are carried on studs G, G, G between straight links H, H and
K, K, which links form a folding frame between the arms B, B of the tongs; so
that when the rollers D, D are rotated they turn with similar relative movements
one with the other, and these movements are the same whether the tongs are in the
open position as shown at Figures 1 and 2 or in the closed position as shewn at
Figure 3.
The arms B, B are provided with stop surfaces L, L, which abut against the
central mandrel A at M, M when the arms B, B are gripped together, thus gauging
the limit of contraction of the rollers D, D. The exterior of the rollers D, D are
formed with screw threads, projections, or indentations corresponding to the form
required to be made on the exterior of the bottle neck; and on the apparatus
being applied to the bottle neck, the tongs are closed thereby bringing the
rollers D, D against the surface of the neck.
The rollers rotate by reason of their contact with the exterior of the bottle neck,
and as the said rollers are geared together, their movements are relatively the same
one to the other, thereby ensuring the indentations of the rollers timing in with one
another and preventing one roller cutting or pressing grooves in different positions
to the other roller.
Instead of employing the spur gearing E, E, F, F, F for the purpose of carrying
the movement from one roller to the other. we sometimes employ chain gearing as
seen at Figure 4, and in this case we employ the wheels E, E and connect same by
chains P, P with two wheels R, R which are connected together and are carried
on a pin S at the junction of the links H, H and K, K.

page_text: Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is: —
1. The links H H, and K K carrying gearing for connecting the rollers D, D
together, substantially as and for the purposes set forth.
2. The combination of the rollers D, D, the spur wheels E, E, and F, F, F and
the links H, H, and K, K, substantially as and for the purposes set forth with
particular reference to Figures 1, 2 and 3 of the accompanying drawing.
3. The combination of the rollers D, D, the spur wheels E, E, and R, R, the
links H, H, and K, K, and the chains P, P, substantially as and for the purposes
set forth with special reference to Figure 4 of the accompanying drawing.
