PROVISIONAL SPECIFICATION.
Improvements relating to Sausage Filling Machines.
I, JOHN HUNT of Baldwin Street Iron Works, Bolton in the County of
Lancaster, Machinist, do hereby declare the nature of my said invention to be as
follows:-
This invention refers to improvements relating to sausage filling machines and
consists in means for driving the same in a ready and efficient manner to produce a
slow forward motion and a quick backward motion to the piston or ram employed
for forcing minced meat through the delivery spout to the sausage skins. This I
effect by fixing to the driving shaft or centre a pinion gearing into a wheel loosely.
mounted on the shaft for driving the rack attached to the aforesaid piston or ram.
To the loosely mounted wheel is attached a spur pinion gearing into a spur wheel
loosely mounted on the driving shaft. To this spur wheel is attached a spur pinion
gearing into a spur wheel fixed on the shaft for driving the aforesaid rack. When.
it is desired to make a forward stroke of the piston or ram for filling sausage skins
it is effected by rotating the driving shaft by means of a handle or other equivalents.
During the operations of driving the shaft it is held in position by a catch or clip
fitting in a groove or grooves. After the piston or ram has completed a slow
forward stroke a quick return or backward stroke is effected by raising the catch
or clip from the said groove to allow of the driving shaft being slid laterally to
remove the fixed pinion thereon out of action with the spur wheel it gears into,
after which the handle or its equivalent is placed on the end of the shaft for
operating the rack to rotate the same in a contrary direction. To dispense with
changing of the handle or its equivalent the driving shaft is fitted with a pinion
which slides into action with the spur wheel on the rack shaft as the other wheels
are disengaged from their respective wheels and pinions by sliding the driving shaft.
In another modification I employ worm and other gearing so arranged that the
worm will remain in gear when making a forward stroke and be slid out of gear
before making a backward stroke, after which the rack shaft may be rotated by a
handle or its equivalent. The whole of the shafts are mounted in bearings attached
to the framework of the machine.

Improvements relating to Sausage Filling Machines.
I, JOHN HUNT of Baldwin Street Iron Works, Bolton in the County of
Lancaster, Machinist, do hereby declare the nature of my 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 refers to improvements relating to sausage filling machines and:
consists in means for driving the same in a ready and efficient manner to produce a
slow forward motion and a quick backward motion to the piston or ram employed
for forcing minced meat through the delivery spout to the sausage skins. This I
effect by fixing to the driving shaft or centre a pinion gearing into a wheel. loosely
mounted on the shaft for driving the rack attached to the aforesaid piston or ram.
To the loosely mounted wheel is attached a spur pinion gearing into a spur wheel
loosely mounted on the driving shaft. To this spur wheel is attached a spur pinion

before making a backward stroke, after which the rack shaft may be rotated by a
handle or its equivalent. The whole of the shafts are mounted in bearings attached
to the framework of the machine.
Fig. is a longitudinal side elevation of a sausage machine with my improvements
applied.
Fig. 2 is a plan of Fig. 1.
Fig. 3 is a plan of gearing in position to produce a quick backward motion.
Fig. 4 is a longitudinal side elevation of a sausage machine with my improvements
applied.
Fig. is a plan of Fig. 4.
Fig. 6 is a side elevation showing worm out of action to allow of a quick backward
motion.
Fig. 7 is a plan of another modification of my invention for making or producing
a slow forward stroke, and Fig. 8 is a plan showing how to produce a quick backward
stroke by gearing in Fig. 7.
In all the figures the same letters are employed to indicate corresponding parts.
A is the cylinder of a sausage filling machine; B the piston; C the piston rod or
rack;
D the framework, and E the spout for delivering minced meat to the sausage
skins. In the framework D is mounted the driving shaft E on the outer end of
which is keyed the pinion F gearing into the wheel G loosely mounted on the
shaft H carrying the pinion I operating the rack on the piston rod D. To the
wheel G is attached the pinion J gearing into the spur wheel K loosely mounted
on the shaft E. To the spur wheel K is attached the spur pinion L gearing into
the spur wheel M keyed on the shaft H. When it is desired to make a slow
forward stroke of the piston B for the purpose of forcing minced meat through the
spout E to fill sausage skins the gearing is in the position shown in Fig. 2 and is
operated by means of a handle or its equivalent placed on the end of the shaft E.
During this operation the shaft E is held in position by the catch or clip N which
fits in the groove O located thereon. The catch or clip N is pivoted to the
framework D by the centre P. After the piston B has completed a slow forward
stroke to force the contents of the cylinder A through the spout E a quick return
or backward stroke is effected by raising or lifting the catch or clip N from the
groove to allow of the driving shaft E being slid laterally as shown in Fig. 3 to
remove the pinion F fixed thereon out of action with the spur wheel G, after which
the handle or its equivalent is placed on the end of the shaft H carrying the
pinion gearing into the rack C, by which the piston B and rod C are operated in
a contrary or backward direction. When the shaft E has been slid to displace the
pinion F from the wheel G as shown in Fig. 3 the catch or clip N is placed in the
groove R in the shaft E, by which it is held during the quick return stroke.
To dispense with the changing of the handle S or its equivalent from the shaft E
to the shaft H for the purpose of effecting the reverse action of the piston B the
driving shaft E is fitted with the extra pinion T as shown in Fig. 7, which is out of

page_text: action when making a slow forward movement to fill the sausage skins. When a
quick return motion is to be effected the shaft E is slid laterally to remove the
pinion L out of gear with the wheel M and place the pinion T in gear with the
wheel M on the shaft H as shown in Fig. 8. In this arrangement when the shaft E
is slid laterally the wheels F, K, and L'are slid therewith carrying or sliding the
wheels J and G on the shaft H as shown in Fig. 8.
In the modification shown in Figs. 4 and 5 the shaft E is fitted with the bevel
pinion U gearing into the bevel pinion V on the shaft W in the bearings X. The
shaft W is provided with the key or feather Y on which is mounted the worm Z
gearing into the worm wheel A¹ on the shaft H. When the piston B is making a
forward motion to fill sausage skins the worm Z is in gear with the worm wheel A¹
as shown in Figs. 4 and 5. When a backward stroke is to be effected the handle S
is removed from the shaft E and placed on the end of the shaft H, and when
the latter is rotated the worm wheel A' will slide the worm Z out of gear on
the shaft W as shown in Fig. 6. When it is desired to make a forward stroke the
worm is placed in gear with the worm wheel A' by hand, and the handle S is
placed on the shaft E.
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 :-
In a sausage machine the respective combinations and arrangements of gear for
driving same to produce a slow forward motion when filling sausage skins and a
quick backward or return motion, substantially as described and as illustrated in
the annexed drawings.
