PROVISIONAL SPECIFICATION.
A Machine for Rolling Bacon and other Substances.
I, JAMES SMYLIE, of 16 Fenuel Street, Manchoster, in the County of
Lancaster, Provision Merchant, do hereby declare the nature of this invention
to be as follows :-
My invention relates to a machine which is particularly applicable for rolling
sides and shoulders of bacon but it is also adapted for rolling hams, rounds of beef
and other substances.
The machine consists of a suitable frame work which carries say four or other
convenient number of wooden or other rollers which are geared together by bands,
chains or toothed gearing so that they all rotate preferably in the same direction.
In addition to the rollers specified there are say two other weighted rollers each of
which is mounted on links or their equivalents so that both rollers can be moved
simultaneously in order to open or close the entrance to a cage or nest formed by
the first named rollers. When the two rollers are opened a side or shoulder of
bacon or other substance to be rolled is introduced into the cage the weighted
rollers are then closed and rotary motion is imparted by hand or power to the
nest of rollers which acting upon the bacon or other substance cause it to be rolled
upon itself under the pressure of the weighted rollers which also rotate.
After the bacon has been sufficiently rolled it is tied by twine applied while the
machine is in motion by a traversing thread guide or by a spiral groove cut along
one of the rollers or in any other convenient manner.

COMPLETE SPECIFICATION.
A Machine for Rolling Bacon and other Substances.
I, JAMES SMYLIE, of 16 Fennel Street, Manchester, in the County of
Lancaster, 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 :-
My invention relates to a machine which is particularly applicable for rolling
sides and shoulders of bacon but it is also adapted for rolling hams, rounds of beef
and other substances.
The machine consists of a suitable frame work which carries say four or other
convenient number of wooden or other rollers which are geared together by bands,
chains or toothed gearing so that they all rotate preferably in the same direction.
In addition to the rollers specified there are say two other weighted rollers each
of which is mounted on links or their equivalents so that both rollers can be moved
simultaneously in order to open or close the entrance to a cage or nest formed by
the first named rollers. When the two rollers are opened a side or shoulder of
bacon or other substance to be rolled is introduced into the cage the weighted"
rollers are then closed and rotary motion is imparted by hand or power to. the

page_text: nest of rollers which acting upon the bacon or other substance cause it to be rolled
upon itself under the pressure of the weighted rollers which also rotate.
After the bacon has been sufficiently rolled it is tied by twine applied while the
machine is in motion by a traversing thread guide or by a spiral groove cut along
one of the rollers or in any other convenient manner.
And in order that my invention may be fully understood and readily carried
into effect I will describe the accompanying two sheets of drawings reference being
had to the figures and letters marked thereon.
Fig. 1 is an end elevation of a machine made according to my invention showing
the two movable rollers open,
Fig. 2 a sectional view of the rollers with the movable rollers closed and a sido
of bacon being rolled, and
Fig. 3 is a front view of Fig. 1.
In the drawings, a represents the frame of the machine, 6 the driving shaft on
which is fitted a pair of fast and loose pulleys 6'; this shaft forms the axis of one
of a nest of four rollers c, d, e and f, which have their bearings in the end
frames a; these four rollers are all driven in the same direction from a spur wheel e
keyed upon the driving shaft b which by means of two carrier pinions 9 and h
gives motion to spur wheels d' and f' one of which is mounted on the axis of the
roller d and the other on the axis of the roller f; the spur wheel d' gears
into a carrier pinion which transmits motion to a spur wheel c¹ fixed
on the axis of the roller c; these four rollers are also connected by
short bands, shown clearly in Figs. 2 and 3, which assist in rolling
the bacon or other substance. On the axis of the roller c are pivoted a pair of
levers and a similar pair of levers k are pivoted to the axis of the roller each
of these pairs of levers carries a roller j' and ' respectively the bearings of which
rest upon springs j' and ' to allow the rollers to yield under excessive pressure
and follow any irregularities in the substance being rolled; these rollers are driven
by bands and from the rollers c and respectively; the ends of the levers k
are connected by cords or chains, see Fig. 1, which pass over guide pulleys/
carried by the levers j; these cords pass down under guide pulleys m carried on
studs in arms a mounted upon a shaft n' which is turned in its bearings by means of
a treadle lever n² and the cords are then carried upward and secured to the frame
at a' the levers ; are connected to the levers k by cords or chains j³, which pass
over guide pulleys o; and from links p attached to the levers k are suspended
weights 9 by cords p¹. The ends of the machine between the rollers j' and k¹ and
the nest of rollers c, d, e and f, are made up by filling up pieces a one only of
which is shown in Fig. 3 a cord's which passes over a guide pulley t supports a
weight and to the other end of this cord is attached a hook, not shown, which
passes through a hole in the end piece a²; a similar weighted hook is employed at
the other end of the machine.
To operate the machine the rollers c, d, e and f, are set in motion and the
attendant puts his foot upon the treadle n³ and pushes it down thus by the cords k³,
lifting the weights 9 and opening and moving the levers j and k into the position
shown in Figs. 1 and 3; a side of bacon or other substance is then doubled and
placed between the rollers and a piece of string u, shown in Fig. 2, is tied to one
end of it the hook on the cords is then hooked into the other end of the bacon
which is drawn by the weight s' up to the filling up piece and is kept square
thereby to complete the rolling process the attendant releases the treadle and the
weights y bring the rollers j' and ' into contact with the bacon and as the rolling
proceeds the attendant guides the string u along a rod u carried by the levers / 30
as to wrap it spirally; when this is done the treadle n³ is then depressed to open
the levers j, k, and allow the roll of bacon to be removed.
;
I wish it to be understood that the machine may be considérably modified in the
details and arrangements of the parts and mechanism without departing from the
nature of my invention which consists essentially in the combination of a nest of
driven rollers with a movable weighted and preferably driven roller or rollers.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. In a machine for rolling bacon and other substances the combination with a
nest of driven rollers, of a movable weighted and preferably driven roller or
rollers arranged to open and close as required the cage or uest formed by the first
named rollers substantially as and for the purposes herein set forth.
2. The general combination and arrangement of parts forming a machine for
rolling bacon and other substances substantially as herein described with reference
to the accompanying drawings.
