HENRY JAMES HOGG KING and THOMAS HOOSLEY ABBOTT, both of Newmarket,
in the County of Gloucester. "IMPROVEMENTS IN SAUSAGE-FILLING MACHINES."
This Invention has for its object, by constructing sausage-filling machines in an
improved manner and so as to be automatic or partly so to save labor and time
in their use.
A machine fitted with the improvements comprises a horizontal cylinder which
is open at one end for the introduction of the meat, and has at its other end a small
tube through which the meat is forced into the sausage skins. A piston is used for
forcing the meat and is drawn back quite out of the cylinder to allow the meat
to be introduced, being held and guided so as to re-enter the cylinder end without
difficulty. In one modification the piston is moved by a screw spindle driven
by means of a spurwheel fixed on its outer end, and this spurwheel gears with
spurwheels driven in opposite directions and with different speeds by means of two
pulleys having between them a third and loose pulley for a driving belt. The fork
for shifting the driving belt is connected to a hand lever, and the worker starts the
machine by setting this lever over so as to put the belt on the pulley which gives
the motion for forcing the piston into the cylinder. On the piston approaching the
end of its stroke a catch on a bar fixed to it acts on a lever connected to the belt-
shifting lever and to a weighted tumbling lever, which last, on the stroke being
completed, causes the belt to be shifted to the pulley giving the return motion.
The return movement is made rapidly, and on its completion a second catch on the
piston bar causes the belt to be shifted back again, but only as far as the inter-
mediate loose pulley which brings the machine to rest, a catch falling into a notch
keeping the parts from shifting. The worker restarts the machine after refilling
the cylinder.
In another modification the piston has a rack-toothed bar attached to it, and is
moved by means of a pinion on a shaft driven from a shaft carrying three pulleys,
as in the first modification. The pinion shaft has fast on it a bevil pinion by
which it receives the quick return motion, the slow forcing motion being imparted
to it by means of a bevil wheel which is loose on it and is fitted with a stud
carrying a long pinion. This stud pinion gears with a fixed spurwheel and with a
11

teeth forming what is known as a differential arrangement, giving a very slow
motion. The belt-shifting lever is connected to a treadle and is acted on by a
weight tending always to shift the belt to the pulley giving the quick return
motion. A movable catch prevents the lever from shifting the belt further than
to the middle or loose pulley, until it is moved out of the way by a projection on
the rack bar on the piston completing its inward stroke. The worker can thus
hold down the treadle whilst a pound or other particular quantity of meat is being
forced out of the cylinder, and then by lifting his foot temporarily stop the machine.
An indicator and dial may be fitted in connection with the piston to show the
quantities of meat being forced out of the cylinder, and a ball or gong may be
arranged to be struck as the piston passes positions corresponding to the successive
pounds or other quantities of meat.
