COMPLETE SPECIFICATION.
Apparatus for Moulding or Pressing "Bunches" for Cigars and
the like Articles.
I, ASHER WOOLF, of Bruce House, 21, Victoria Park Road, London, E., Gentle-
man, 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:
My invention relates to apparatus for moulding or pressing "bunches" for
cigars and the like articles and has for its object to provide a handy tool whereby
to enable the workman to press or mould the "bunches" for cigars (or other
articles) to the desired form in small quantities as the work of manufacture pro-
ceeds and to leave them under pressure for the time necessary to bring them to
their required or finished form.
The invention consists essentially in the means whereby the parts of the mould
may be readily closed together and subjected to the required pressure and it will
be described with reference to the accompanying drawings forming part of this
specification wherein Figure 1 represents a front elevation (partly in section) of
a pair of moulds constructed according to my invention, the moulds being in the
closed position. Figure 2 is a plan of the same. Figures 3 and 4 are elevations
of one end, showing the closing mechanism in the operative and inoperative
positions respectively.
The moulding and pressing apparatus comprises a two-part mould of the usual
form namely a bed mould A having transverse cavities a of approximately semi-
circular section at the lower part with vertical sides at the upper part, and of a
length and configuration corresponding to the form to which it is desired to
mould the "bunches" for cigars (or other articles) and a removable top mould B
having on its lower face plungers or projections 6 of a form adapted to fit between
the vertical sides of the cavities a and of approximately half-round form in cross
section. The "bunches" for cigars (or other articles) to be moulded are placed
in the cavities a and the coincidence of the top mould with the bottom mould, and
the vertical motion of the former in the pressing operation, are ensured by steady
pins c on the one entering holes in the other. The pressure is applied and main-
tained by the following combination of mechanism:-D is a pressure bar pivoted
at d on top of the mould B so that its ends may be swung out of the way to admit
of insertion or removal of the mould, or be brought into such position that its
ends project sufficiently beyond the ends of the top mould B to enable them to be
engaged by the upper hooked ends e of presser slides E fitted to slide up and down
on the ends of the bottom mould A, the two presser slides being actuated simul-
taneously by a pair of cams F fast upon the same shaft G which extends
longitudinally through or beneath the bottom mould and is provided with a
removable lever handle H for operating it. The shaft G passes through a
vertical slot 9 in each of the presser slides E by which slots g and by fixed studs I
passing through slots i the said plates are guided in their up and down movement.
The cams F when rotated so as to effect the closure of the mould, act on outwardly

page_text: turned flanges f at the lower ends of the slides E and are of such radius that when
turned into operative position the hooks e will be caused to press upon the ends
of the bar D and draw down the top mould B tightly upon the bed mould A,
the extent of the downward movement of the slides E being slightly greater than
that of the top mould B so as to ensure perfect closure of the mould, the continued
descent of the slides E, after the top mould B has come to rest, being permitted
by the upturned ends of the presser bar 1) acting as very stiff springs. Said
springs also serve, in conjunction with a flat f¹ on each cam, to limit the motion
of the shaft so that the cams will be- self retaining in operative position and will
maintain the pressure on the moulds as long as may be required. The slides E
are raised, so as to permit of the bar I being swung. aside and the moulds A B
being separated by the cams F, when rotated in the reverse direction, engaging
with, studs e on the slides...

Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
-
Apparatus for moulding and pressing "bunches" for cigars and the like
articles, consisting in the combination with a two-part mould as described, of
mechanism for applying and maintaining pressure thereon, the said mechanism
consisting of cam-operated pressure, slides adapted to engage with a swing bar
upon the top mould, the mechanism at the two ends being adapted to be actuated
simultaneously from a shaft common to both substantially as shewn and described.
