Improvements in what are Commonly known as Silent Mincing
Machines."
I THOMAS WILLIAMS the Younger of 45 Myddelton Square in the County of
Middlesex Engineer do hereby declare the nature of the said 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 upon the machine described in the
specification to my patent No. 732 A.D. 1880. Its chief objects are to simplify and
cheapen construction and facilitate packing for transport.
It relates first to an improved arrangement whereby all the bearings for the bowl
spindle and the first motion shaft are mounted upon or carried by a single arm or
bracket conveniently secured by bolts or otherwise to the bowl plate of the machine,
in lieu of being mounted upon various parts of the supporting framework. I am thus
enabled to dispense with the cumbrous and costly framework before employed and
may support the machine upon light legs formed of angle iron and bolted or otherwise
detacheably secured to the bowl plate These legs or supports can be readily removed
when it is desired to pack the machine for transport, without interfering with the
working parts thereof, thus permitting the whole machine to be packed into a small
compass with very little labour.
My invention further relates to an improved arrangement for securing the knives to
and upon the knife boss so that any single knife may be quickly and easily removed
when required without interfering with the rest, whilst all loose collars are dispensed
with.
I will now proceed to describe my invention more particularly referring to the
accompanying drawings in which similar letters indicato similar parts in all the
figures.
Fig. 1 is an elevation of the machine looking from the back, shewing, attached to
the bowl plate thereof the bracket or arm carrying the bearings for the bowl spindle
and first motion shaft.
Fig. 2 is a detached end view of the bracket or arm, partly in section on line 1-2
in fig. 1.
Fig. 3 is a plan of the bracket or arm detached.
Fig. 4 is a detached view of the knife boss the knives being removed.
Fig. 5 is a detached view of one of the knives.
Figs. 6 and 7 are detached views of the knife boss with the knives secured
thereto.
a is the bowl plate of the machine to which are detacheably secured by bolts 6 or
otherwise the legs or supports & shewn in dotted lines. c is the bracket or arm which
carries the bearing d of the bowl spindle g and the bearings e and of the first motion
shaft, the extremities of this bracket or arm c being bolted to the bowl plate a of the
machine at c¹. It will be readily seen from this figure that the legs or supports are
quite independent of the working parts of the machine, and may be easily and quickly
removed and the whole machine packed into a small space for transport, while all
heavy and costly supporting framework is dispensed with.
i fig. 4 is the knife boss mounted on the cutter shaft k, 11 are grooves about equal
in depth to the thickness of the knives m (fig. 5) such grooves being formed one in
each face of the knife boss, and disposed at or about right angles to each other.
(fig. 5) is a recess formed in the butt end of each knife m to permit it to partially
embrace the cutter shaft .k, and thus secure additional firmness. The knives m are
placed two in each groove l, with their extremities abutting as shewn in figs. 6 and 7
and secured to the knife boss each by a single bolt and nut o, all loose collars being

page_text: entirely dispensed with. In order to secure adjustment of the knives m each is pro-
vided with a slot for its bolt o to pass through so that by simply loosening the nut on
such bolt the knife may be shifted in its groove and adjusted as desired. Should it
be desired to remove a knife all that is requisite is to remove a single nut when it can
be at once detached without disturbing or interfering with the other knives.
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
1. In a mincing machine of the class described, mounting all the bearings for the
bowl spindle, and the first motion shaft upon a single arm or bracket secured to the top
plate of the machine substantially as and for the purpose described and illustrated by
my drawings.
2. In a mincing machine of the class described, the use in combination therewith of
the arm or bracket c, carrying the bearings d, e, f, substantially as described and
illustrated in figs. 2 and 3 of my drawings.
3. In a mincing machine of the class described the peculiar arrangement for
securing the knives to the knife boss substantially as and for the purpose described
and illustrated by figs. 4, 5, 6 and 7 of my drawings.
4. In a mincing machine of the class described the use in combination with the
knives m, and fixing bolts and nuts o, of the knife boss i, having grooves formed one
in each face and disposed at or about right angles to each other substantially as
described and illustrated by figs. 4, 5, 6, and 7, of my drawings.
