IMPROVEMENTS IN AND IN CONNECTION WITH MILL OR LINE SHAFTING
Year: 1885

page_text: I HERBERT FORD SMITH, of Hadfield Street Works, Cornbrook, Manchester, in
the County of Lancaster, Machinist do hereby declare the nature of the said
invention for "IMPROVEMENTS IN AND IN CONNECTION WITH MILL OR LINE
SHAFTING," to be as follows:-
My invention consists in improved combinations and arrangements of parts.
The hanger or carrier for the shafting is formed to have a bracket secured to it
by one or more bolts, which admit of slight adjustments and thore is a screw that
screws through a projection on the hanger and into a hole in the bracket to obtain
vertical adjustments thereof, and there is also a screw acting on the lower part of
the bracket to give horizontal adjustment one way.
The bracket is formed to receive a bearing the outer underside of which is partly
spherical and rests on two points of the bracket on one side, and upon one point on
the other side, and this allows the bearing to adjust itself to the journal on the
shaft, when it is secured by one bolt passing through the end of the bracket and
through an ear from the bearing, the opposite side of the bearing coming under a
projection on the bracket.
The bearing forms a complete cylinder at each end but the upper part is cut
away between each end to form a cap which can be readily removed for inspection
or lubrication, and then be replaced.
The shafts to be coupled are formed to come end to end, one shaft overlapping
the other to a short extent.
My improved coupling for the shafting is formed by a part which is or may be
a cylinder externally with an internal flange at one end-The interior of the
cylinder is bored out conically the cone being of the same inclination and direction,
from end to end.
In the cone of the coupling two loose cones are placed which are each bored out
to fit the ends of their respective shafts and two bolts or screws are used for each
loose cone to draw them within the internal cone of the coupling in the direction
of the line of the shafts, and thus cause each of them to firmly grip the end of
their respective shafts.
Both sets of bolts or screws pass through the internal flange at one end of the
coupling.

page_text: The two loose cones are formed out of one solid piece, first bored out to fit the
shafts and then turned on the exterior to fit or correspond with the internal cone
in the coupling and then they are cut apart, and are slit longitudinally so as to be
elastic and able to close upon the shafts when compressed by being drawn into the
internal cone of the coupling.
The holes or slots for the bolts or screws to pass through or screw into are
arranged so that the bolts or screws can only be placed in position, when the loose
cones are in the same position in relation to each other as they were when bored
and turned, before they where separated, so that should there be any slight
excentricity it will be thrown upon the exterior of the coupling and will not affect
the shafts which will remain true to each other-Both loose cones being tightened
by bolts or screws drawing into one cone, the couplings can be forced or driven
on and off in one direction.

page_text: I HERBERT FORD SMITH of Hadfield Street Works, Cornbrook, Manchester, in
the County of Lancaster, Machinist, 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 consists in improved combinations and arrangements of parts.
The hanger or carrier for the shafting is formed to have a bracket secured to it
by one or more bolts, which admit of slight adjustments and there is a screw that
screws through a projection on the hanger and into a hole in the bracket to obtain
vertical adjustments thereof, and there is also a screw acting on the lower part of
the bracket to give horizontal adjustment one way,
The bracket is formed to receive a bearing, the outer underside of which is partly
spherical and rests on two points of the bracket on one side, and upon one point
on the other side and this allows the bearing to adjust itself to the journal on the
shaft when it is secured by one bolt passing through the end of the bracket and
through an ear from the bearing, the opposite side of the bearing coming under a
projection on the bracket.
The bearing forms a complete cylinder at each end but the upper part is cut
away between each end for a cap which can be readily removed for inspection
or lubrication, and then be replaced.
The shafts to be coupled are formed to come end to end one shaft overlapping
the other to a short extent.
My improved coupling for the shafting is formed by a part which is or may be
a cylinder externally with an internal flange at one end-The interior of the
cylinder is bored out conically the cone being of the same inclination and direction
from end to end.
In the cone of the coupling two loose cones are placed which are each bored out
to fit the ends of their respective shafts and two bolts or screws are used for each
loose cone to draw them within the internal cone of the coupling in the direction
of the line of the shafts, and thus cause each of them to firmly grip the end of
their respective shafts.
Both sets of bolts or screws pass through the internal flange at one end of the
coupling. The two loose cones are formed out of one solid piece, first bored out to
fit the shafts and then turned on the exterior to fit or correspond with the internal
cone in the coupling and then they are cut apart and are slit longitudinally so as
to be elastic and able to close upon the shafts when compressed by being drawn
into the internal cone of the coupling.
The holes or slots for the bolts or screws to pass through or screw into are
arranged so that the bolts or screws can only be placed in position when the loose
cones are in the same position in relation to each other as they were when bored
and turned, before they where separated, so that should there be any slight
excentricity it will be thrown upon the exterior of the coupling and will not
affect the shafts which will remain true to each other-Both loose cones being
tightened by bolts or screws drawing into one cone, the couplings can be forced or
driven on and off in one direction,

a is the hanger secured to a floor beam or other carrier above it by bolts a¹.
b the bracket for carrying the bearing which bracket has one or more bolts b¹
(two are shown) passing through it which bolts also pass through vertical slots a² in
the hanger, so as to allow the bracket b to be adjusted vertically by a screw b²
which passes through and rotates in a hole or slot in the projection a" from the
hanger a the threaded end of which screw 6ª screws into and fits a screw tapped
hole in the bracket b.
In the lower part of the bracket b there is a horizontal screw tapped hole into
which the end of a screw b³ is screwed which screw has two screw nuts b* upon it,
one on each side of the hanger (a) so that by adjusting these screws the horizontal
position of the bracket b is adjusted, when the screw nuts 6* may then be firmly
screwed to the hanger (a) which has a vertical slot a to admit of the bracket b
and thus the screw 63 boing adjusted vertically which is first effected while the
screw b³ is free from the hanger before the horizontal adjustment is made.
The hollow of the bracket b for the bearing c has two projections 65 from it on
the hanger side and one on the opposite sido and the underside of the bearing c is
partly spherical, this spherical part resting upon and between the said projections b
which thus allow the bearing to adjust itself to the line of the shaft.
The inner edges of the bearing c comes under a projection 6 from the bracket b
and there is an ear c¹ from the outer edge of the bearing having a hole through it
for a bolt c² passing through a hole in the bracket bas shown in figs. 2 and 4.
By tightening this bolt c when the bearing has adjusted itself to the shaft x
the bearing is slightly drawn down on the outside and the upper inside edge of
the bearing is brought in close contact with the projection 66 on the bracket b.
The bearing c for a length at its two ends c³ completely encircles the shaft
but within the gap formed between the two ends of the bearing there is a cap d
placed which can be removed for lubricating or other purposes and replaced to
prevent adinission of dirt.
The bracket b at its lower edge has a projection 67 upon each side which have
or may have a double incline on their upper faces as shown in dotted line in fig. 2.
Upon these projections b' a dish e to catch any oil or lubricant flowing from the
bearing is suspended by projections e¹ from the dish & hooking upon the
projections 67.
Figs. 5 and 6 show the same arrangement of bearing as that above described in
reference to figs. 1, 2 and 4 except that the bearing is shown combined with a s
pedestal b bolted by bolts a¹ to any suitable carrier or support.
In figs. 1 and 3 the mode of coupling the shafts is illustrated.
The ends of the two shafts x to be coupled are made by preference to overlap as
shown best in fig. 1.
The coupling is a cylinder f with an internal flange f1 at one end, and it is
turned or bored out internally so as to be coned from one end (which is the larger
end of the cone hole) to the inner flange f¹ at the other end-the internal cone
being of the same inclination from one end to the other. Two cones g'and gx are
fitted into the coupling, but they are formed out of a part cast in one piece, bored
out to accurately fit the ends of the shafts and then the exterior ribs g¹ are 5
turned to accurately fit the interior cone in the coupling when the smaller end of
the cones g is about half an inch more or less from the internal flange f¹ then a

page_text: space is cut out of the middle of the casting to make the two cones g and g*
separate as shown in fig. 1.
There is a notch or projection on each cone at that end of it against which the
head of each bolt comes the bolt coming between one of the ribs g¹ and the
projection.
Two bolts g³ and g³ are used for each cone g and g* and they pass between the
notch formed between the projection and rib g and through corresponding holes in
the internal flange ƒ¹.
It will be seen that the two short bolts g³ for the inner cone g are on directly
opposite sides of the shaft x, so are the long bolts g³ for the outer cone g*, but it
will be observed that a plane passing through the centres of the two bolts g³ for
one cone is not at a right angle to the plane passing through the centres of the
other bolts g for the other cone and the cones thus can only be bolted in position
within the coupling when they are in respect to each other in the same position as
that in which they were turned when in one piece, so that when screwed tight
should there be any slight excentricity it will be thrown upon the exterior of the
coupling, the interior and the shafts remaining concentric.
The cones g and g* when bored and turned are slit open longitudinally and
being made thin with webs or ribs g¹ they are elastic and close firmly upon the
shafts when drawn into the coupling by the bolts g³ and g³.
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. The combination, arrangement and construction of hangers and bearings for
shafts, substantially as herein before described and illustrated by the drawings.
2. The combination, arrangement and construction of bearings and pedestals for
shafts, substantially as hereinbefore described and illustrated by figs. 5 and 6 of
the drawings.
3. The combination, arrangement and construction of parts for coupling the ends

the same direction, substantially as hereinbefore described and illustrated by figs. 1
and 3 of the drawings.
