I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Engineer do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in apparatus for the fastening of capsules on
bottles, jars, and the like and it has for its object to provide an arrangement which
besides giving the radial moving jaws of the apparatus a uniform motion, transmits a
great pressure onto the capsules by a proportionately small pressure on to its lever.
In the accompanying drawings:-
Figure 1 represents an apparatus the levers of which are only shown as straight
lines.
Figuro 2 is a front view of an improved apparatus the jaws of which are closed.
Figure 3 the same with the jaws open.
Figure 4 is a side elevation without the india rubber jaws.
Figure 5 a back view of the apparatus with closed jaws.
The jaws a' a² a³ constructed as usual of india rubber or other elastic material are
attached to slide blocks 6 6 6 which move radially towards the centre in the
guides ccc which latter are fastened to the frame d.
The slide blocks are moved by the lever e which transmits the power to the toggle
levers f¹ff.
In Figure 1 an apparatus is represented in which all three slide blocks are moved
by toggle levers. The knees g' g³ of the toggle joints f¹fare in direct communi-
cution with the working point i of the lever e by the arms h h while the knee g³ of
the toggle joint is operated by the lever e through a cord k¹ running over a pulley A
fastened to the frame d and attached to the knee gas well as to the working point i of
Duine 1111

page_text: the lever e. The backward i.e. upward movement of the slide & results from the
falling of the counterweight G attached to the cord which running over a pulley (*
is attached to the knee of the toggle joint ƒ³.
Figures 2, 3, 4 and 5 represent an apparatus in which the toggle joint transmission
is only used for two of the slide blocks while the third upper one is directly in
communication with the lever e by the arm h³. In this case the arm ³ must be
placed nearer to the fulcrum or pivot m of the lever e so that the directly moved slide
block may have the same power transmitted to it as the slide blocks operated
by the toggle joints ƒº¹ƒ”.
As the transmission of power by the toggle joints may be increased at will by
altering the angle of the toggle levers it follows that the fixing of the capsules can be
done in a minimum of time or with a minimum of power on the hand lever e.

page_text: I, ALFRED JULIUS BOULT of 323 High Holborn in the county of Middlesex,
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention relates to improvements in apparatus for the fastening of capsules on
bottles, jars and the like and it has for its object to provide an arrangement which
besides giving the radial moving jaws of the apparatus a uniform motion, transmits a
great pressure onto the capsules by a proportionately small pressure onto its lever.
In the accompanying drawings: -
Fig. 1 represents an apparatus the levers of which are only shown as straight
lines.
Fig. 2 is a front view of an improved apparatus the jaws of which are closed.
Fig. 3 the same with the jaws open.
Fig. 4 is a side elevation without the indiarubber jaws.
Fig. 5 a back view of the apparatus with closed jaws.
Fig. 6 is a front view of a further improved apparatus.
Fig. 7 is a side view of the same partly in section.
Fig. 8 is a front view of another modification.
Fig. 9 is a side view of the same, partly in section.
The jaws a', a', a³ constructed as usual of india rubber or other clastic material
are attached to slide blocks b', 63, 6 which move radially towards the centres of the
guides c, c², which latter are fastened to the frame d. The slide blocks are moved
by the lever e which transmits the power to the toggle lovers ƒ³‚ƒ³‚ƒ³.
In figure 1 an apparatus is represented in which all three slide blocks are moved by
toggle levers. The knees g', g³ of the toggle joints f¹, f' are in direct communication
with the working point i of the lever e by the arms h', ' while the knee g of the
toggle joint is operated by the lever e through a cord k³ running over a pulley
fastened to the frame d and attached to the knee g³ as well as to the working point i
of the lever e. The backward i.e. upward movement of the slide results from the
falling of the counterweight G attached to the cord which running over a pulley /
is attached to the knee g of the toggle joint f³.
Figs. 2, 3, 4 and 5 represent an apparatus in which the toggle joint transmission
is only used for two of the slideblocks while the third upper one 6 is directly in
communication with the lever e by the arm h³. In this case the arm ³ must be
placed nearer to the fulcrum or pivot m of the lever e so that the directly moved
slide block may have the same power transmitted to it as the slideblocks 6', b³
operated by the toggle joints ƒ³,ƒ³.

page_text: As the transmission of power by the toggle joints may be increased at will by
altering the angle of the toggle levers it follows that the fixing of the capsules can
be done in a minimum of time or with a minimum of power on the hand lever e.
Figs. 6 and 7 represent an apparatus in which all three slideblocks are operated
by toggle joints.
In this instance the lever e is formed as a large ring provided with a handle E
and working in suitable guides m³, m³, m³ on the face of the apparatus. To this
ring e are pivotted tho rods ', 2, 3 which are attached with their other ends to the
knees of the toggle joints as before so that when the ring e is turned by the handle
these rods ',, will operate the toggle joints and the slideblocks in the manner
already described.
Figs. 8 and 9 represent a modification of the apparatus especially adapted for small
work. The construction of the apparatus is substantially the same as the one
represented in figures 6 and 7 only that in this instance the whole of the slide-
blocks are directly operated by the rods 1, 2, 3 which are pivotted at one end to
the ring e and at the other to the slideblocks direct the rods being preferably of
such length that they are not parallel with the path of the slideblocks when the jaws
are closed.
Having now particularly described and ascertained the nature of the said invention,
as communicated to me by my foreign correspondent, and in what manner the same
is to be performed, I declare that what I claim is :-
1. In an apparatus such as described the combination with one or more of the
slideblocks 6, 3, 63 carrying the compressing jaws of toggle joints f,f³, ƒ³ operated
directly or indirectly from the lever e substantially as specified.
2. In an apparatus such as described the combination with lever e and toggle
joints of cords k¹, and weight G substantially as specified.
3. In an apparatus such as described the combination with lever e which operates
the toggle joints and slide blocks of a lever ³ connected at one end directly with the
slideblock and at the other to lover e but nearer the fulcrum m than the point i
from which the toggle joints are operated in such manner that the power applied
to the slideblock by shall be equal to that applied to the toggle joints substantially
as specified.
4. In an apparatus such as described the combination with the circular lever e the
toggle joints, and slideblocks b¹, b³, b³ of the rods h³, h³, h³ pivotted at one end
to the ring e and at the other to the knoes of the toggle joints substantially as and for
the purpose specified.
5. In an apparatus such as described the combination with the circular lever e and
the slideblocks b', 63, of the rods h1, h2, h3 pivotted at one end to the ring e and at
the other to the slideblocks direct, substantially as and for the purpose specified.
