An Improved Engine for Moving Yarns and other Materials in Vats
and similar Vessels.
We, WILLIAM HEWETSON LORIMER, Dyer, and JOHN WASHINGTON BIRKEY,
Machinist, both of Bristol, in the County of Bucks, State of Pennsylvania, United
States of America, 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 :-
Our invention relates to improvements in machinery for dyeing yarns or other
substances, and the object of our invention is to furnish an improvement in engines
for moving the yarn or other substance in the' dye liquid in the kettle or vat so
that it will be quickly and evenly dyed throughout.
In the accompanying drawings forming part of this Specification and in which
similar letters of reference indicate similar parts throughout the several views,
Figure 1, is a front elevation of a dyeing kettle, the cage in which the yarn is
held, and our engine for moving the cage up and down in the liquid in the kettle;
Figure 2, an enlarged front elevation of our engine for lifting the cage ;
Figure 3, a plan of Figure 2, and
Figure 4, a plan of disk, Figures 1 and 2, showing handle by means of which
this disk and the parts connected thereto may be moved by hand.
A is an upright cylinder which is furnished at its upper end with a stuffing box B
and within which is a piston C and a piston rod D which passes upward and out
through the stuffing box B. E, F, G, H, are pipes the former of which, that
is E, F, enter the upper part of the cylinder, A, preferably at opposite sides as
shown, and the latter of which, or G, H, onter the cylinder, preferably at opposite
sides, at its bottom. Upon the pipes E, F, G, H, are valves E', F, G, H', which
control the flow of the stoam or water to the cylinder A or away from the cylinder.
In the drawings E', G', are the inlet valves, and F, H', the exhaust valves.
Connected to the valves E, F, G, H', are levers E, F, G, H, and connecting
the ends of levers E, F, is a link I, and connecting the ends of levers G³, H', is
a link J. K is an adjustable rod connecting the ends of levers E, G. Lan
adjustable rod connecting the ends of levers F, H. The rods K, L, are made in
two pieces the inner ends of which are threaded and connected by a sleeve nut M
as shown. Pivoted to the cylinder A is a disk N which carries rollers O, P, the
former adapted to strike and raise the link to open the inlet valve El and close
the exhaust valve F', the latter to strike and lower the link J to open the inlet
valve G and close the exhaust valve HI, or vice versa as hereinafter described.
R is a pio secured to disk N. S a connecting rod carried by the upper end of
piston rod D which is furnished with two hooks or catches S, S', the former of
which is adapted to engage piu R and move this pin downward when the piston rod
has almost reached the end of its downward stroke, and the latter of which is
adapted to engage and move this pin upward when the piston rod has almost
reached the end of its upward stroke.
To the upper end of the piston rod is attached one end of a cord or chain T, Fig. 1,
which passes around pulleys U and has its other end attached to the cage V which
carries the yarn to be dyed.
The machine being in the position shown in the drawings, steam or water is
admitted into the lower part of the cylinder A and raises the piston C and piston
rod D which draws up conuecting rod S and hook S' upon its lower part which

page_text: presently engages pin R on disk N causing this disk to turn upon the pin N' by
means of which it is secured to cylinder A. The roller O now engages and lifts
link I which throws over arms or levers E, F, opening the inlet valve E' and
closing the exhaust valve F¹. Steam or water is now admitted to the upper part
of cylinder A and forces the piston rod C and its connected parts downward until
the hook S' on connecting rod S strikes pin R and moves disk N around causing
roller P to strike and move down link J, which, through arms G', H', closes the
exhaust valve H' and opens the inlet valve G' when the movement of the parts is
reversed as already described.
The roller P may be done away with if desired and the valves operated by the
falling of the arms and levers connected to them when the pin R is struck by
hook S' aud the roller O moved away from link I.
slot a.
a is a slot in disk N, ba pin carried by the cylinder A which passes through
This pin and slot limit the movements of the disk N in either direction.
c, best shown in Fig. 4, is a handle by means of which the disk N may be
operated by hand.
The device is preferably set so that during its operation the stroke of the
piston C will be considerably shorter than the length of the cylinder A.
When it
is desired to remore the cage from the kettle the connecting rod S is moved out of
operative contact with the pin R and steam or water is admitted to the upper
part of cylinder A and drives the piston down to the bottom of the cylinder and
the cage is lifted clear of the kettle, the cage can now be moved away from the
kettle and steam or water admitted to the bottom of the cylinder when the piston
will rise and lower the cage to the floor, or to a truck upon which the cage and
yarn may be carried away. The same effect may be produced, if the machine
is worked at the full stroke of the cylinder A, by securing the cage V when it is
in its highest position in the kettle, then raising the piston and piston rod to their
highest positions, shortening the cord or chain T, and then lowering the piston and
piston rod which will lift the cage clear of the kottle.
In Fig. 1, d is a valve by means of which the flow of steam or water to the
inlet valves E', G', may be controlled.
Having now particularly described and ascertained the nature of our said inven-
tiou, and in what manner the same is to be performed, we declare that what we
claim is:
1. The combination of an upright cylinder, a piston and a piston rod within
said cylinder, un inlet and an exhaust valve at the upper end of said cylinder, an
inlet and an exhaust valve at the lower end of said cylinder, arms or levers
connected to said valves, links connecting the ends of the levers on said inlet and
exhaust valves, adjustable rods connecting the levers on said inlet valves, adjustable
rods connecting the levers on said exhaust valves, and means, operated by the
movements of the piston rod, for alternately opening and closing said inlet and
exhaust valves.
2. The combination of an upright cylinder, a piston and a piston rod within
said cylinder, an inlet and an exhaust valve at the upper end of said cylinder, an
inlet and an exhaust valve at the lower end of said cylinder, arms or levers
connected to suid valves, links connecting the ends of said levers on said inlet
and exhaust valves, adjustable rods connecting said levers on said oxhaust valves,
a disk, pivoted to said cylinder and adapted to alternately engage the links connecting
the inlet and exhaust valves, a pin on said disk, a connecting rod carried by said
piston rod, and hooks on said connecting rod adapted to alternately engage said
pin and to move said disk.
3. The combination of an upright cylinder, a piston and a piston rod within said
cylinder, an inlet and an oxhaust valvo at the upper end of said cylinder, arms or
levers on said valves, a link connecting said arms or levers, an inlet and an
exhaust valve at the lower end of said cylinder, arms or levers on said valves, a
link connecting said arms or levers, adjustable rods connecting anid arms on said

page_text: inlet valves, adjustable rods connecting said arms on said exhaust valves, a disk
pivoted to said cylinder, a stop for limiting the movements of said disk, a pin on
said disk, a handle formed by said pin, rollers carried by said disk adapted to
engage links connecting said arms ou said inlet and exhaust valves, a connecting
rod carried by said piston rod, and hooks on said connecting rod adapted to
alternately engage said pin on said disk.
