COMPLETE SPECIFICATION.
Bacon Cutting Machine.
I, CHARLES WILSON, c/o J. Jeffrey 5 Chesterfield Street, W.C. Provision
Merchant, 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:-
The object of this invention is to facilitate the cutting or slicing of bacon or
other like substances.
In carrying ont ny invention, I employ an endless band saw, preferably of special
construction, and operated by means of sheaves or pulleys which may be driven by
hand, steam, or other suitable motor. This band saw is used in conjunction with,
or in proximity to, a table capable of being slid to and fro by the operator, and
upon which rests the article to be sliced or cut, adjustably held thereon by means
of points or guides projecting from the upper surface of the table. By these means
the bacon or other article may be pushed up against the cutting edge of the saw
and brought back again preparatory to repeating the operation.
In order to clean the saw of grease which accumulates thereon and which would
otherwise prevent the proper driving effect of the pulleys, I employ one or more
"grease-cleaners" which will be hereinafter described.
Having thus described the nature of this invention, I will now proceed to
describe the manner in which it may be carried into effect, reference being had to
the accompanying drawings which illustrate one form of my machine by way of
example.
The same letters of reference indicate like parts in the several figures.
Figure 1 shows by front view an elevation of the machine and
Figure 2 shows a side elevation of the same.
Figure 3 shows by a like view to Fig. 1. an elevation of the saw together with
the grease cleaning apparatus.
Figure 4 is a side view of the parts shown in Fig. 3 and
Figure 5 is a plan view of the same.
a is the band saw passing over two pulleys 6 and 6' which are rotated by means
of the driving axis c and upon the latter may be fixed the driving pulley c¹, the
handwheel and the crank c. The upper and lower sheaves b and 6' are carried
in suitable bearings and supported by means of brackets d' and d³, d² respectively,
which may be rigidly connected to, or form part of, a bed plate d. This bed-
plate d, which may be supported upon a counter or other suitable base, carries the
sliding table e, and is constructed with a number of ribs d having grooves d in the
upper parts thereof, in which run a series of rollers or bearings e¹ in order to reduce
the friction of the moving table e. This table e is provided with a convenient
number of spikes e³, e², or holders, which help to keep the article steady when cutting
г.

page_text: thin slices. The moving table is also formed with a long narrow slot, (not shown
on drawings) extending through the greater part of its length from front to rear,
(through which the saw passes) to allow the sliding motion to take place.
The "grease-cleaners" I preferably place immediately underneath the sliding
table e, see Fig. 1, but are shown more clearly in section by Fig. 3, and in plan
view by Fig. 5. which illustrate a convenient form of the apparatus. In the
drawings two cleaners are shown, one directly above the other, and each is con-
structed essentially of two blocks ff, say of wood, the inner surfaces of which, ff,
next to the saw, are covered with leather or other suitable substance. Part of the
upper surfaces of the blocks are sloped downwards and outwards so as to
allow the grease to run down clear of the saw, and down through the grooves or
slots, ff, into suitable receptacles. The blocks are shown fitted to the
framework of the bedplate d and provision is made for obtaining the necessary
amount of friction by means of a spring f which is inserted between the framework
of the bedplate d and one of the wood blocks f; or this friction may be obtained by
means of a thumbscrew or other suitable contrivance.
In order to effect a cut or slice cleanly and quickly, I form a band saw having
one of its cutting edges with its length partly saw teeth and partly knife edge, the
action of which is as follows:-In an ordinary piece of bacon, say with a bone
about the middle, I would commence the cut as soon as the knife edge was brought
around to the article and push the table along thereby slicing the fleshy part by
means of the knife-edged portion, when the length of the saw which is teethed
would arrive at the cutting point and saw through the bone whilst the remaining
fleshy part, if any, could be sliced by the knife edge coming around again. For
ordinary work I find that about 3 feet of saw teeth to about 5 feet of knife edge
to be very convenient, but I do not limit myself to these lengths. The other edge of
the saw blade may
be made either having a knife edge or entirely saw teeth, or a com-
bination of both. In order to get the necessary frictional contact between the saw
and its driving sheaves and b¹ I preferably cover the surfaces of the sheaves with
leather or other suitable material, which is assisted by having holes a' formed at
intervals in the saw blade a thereby sustaining the "grip." Attached to the
underside of the bedplate d, is a brush 2, close to the driving surface of the bottom
sheave and of such a form to overlap and brush the edges as well as the circum-
ference. The upper sheave is provided with a guard and a splash board 6 both
of which are so attached as to be readily removed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A bacon cutting machine in which the article to be cut is placed upon a
moving table capable of being operated in combination with an endless band saw
substantially as and for the purpose hereinbefore set forth.
2. The general arrangement and combination of bacon cutting machine com-
prising the band saw together with the moving table, in combination with the
apparatus described herein for automatically clearing the grease from the saw.
3. The construction of the band saw having a cutting edge partly toothed and
partly with a knife edge substantially as herein before described and shown.
