EDWARD THOMAS HUGHES, of the Firm of Hughes and Son, Patent Agents,
123, Chancery Lane, London. "IMPROVEMENTS IN SHAFT HANGERS." A com-
munication from abroad by Henry Dewey Cone, of Stockbridge, County of Birk-
shire, State of Massachusetts, United States of America.
This Invention relates to an improvement in that class of hangers or bearings
used to support shafting employed in the driving or working of machinery, appli-
cable alike to "overhead," "post," or "floor" supports, the object being to adjust
the bearing after the hanger and shaft are in place, and so that the shaft may be
removed and re-turned to place without the necessity of re-adjustment, and it
consists in the construction as hereinafter described.
On the accompanying Sheet of Drawings,-
Fig. 1 is a front view.
Fig 2a sectional side view
Figs. 3 and 4, detached views.
As represented in Figs. 1 and 2, the Invention is shewn as applied to a post
hanger, and in which A. is the plate by which the hanger is secured to the post.
From this an arm B projects outward with a horizontal opening C, or it may be a
pair of arms with a space between, or simply a single arm. In the open space C,
or between the two arms, or on the top of the single arm, a nut D is arranged with
convenient provision for turning, here represented as perforations in the periphery
Figs. 3 and 4, detached views.
As represented in Figs. 1 and 2, the Invention is shewn as applied to a post
anger, and in which A. is the plate by which the hanger is secured to the post.
From this an arm B projects outward with a horizontal opening C, or it may be a
pair of arms with a space between, or simply a single arm. In the open space C,
or between the two arms, or on the top of the single arm, a nut D is arranged with
convenient provision for turning, here represented as perforations in the periphery
of the nut. Through this nut a correspondingly threaded shank E is introduced,
and so that by turning the nut, which is stationary in the direction of its axis,

page_text: the shank E will be raised or lowered, accordingly as the nut is turned to the right
or left.
Below the support of the nut the shank E is divided to form a pair of supporting
arms F, F. At the lower end of these arms, extending from one to the other, is a
bolt G, and on this bolt is a screw threaded sleeve H arranged so as to be turned
freely on the bolt, but so as to be prevented from longitudinal movement, here shown
as extending from one arm to the other, the two arms forming stops to prevent
such longitudinal movement.
Lis the lower part of the box or bearing, and has upon its under side a trans-
verse socket N, screw threaded to correspond to the sleeve H, is introduced before
being placed upon the bolt G, and so that by turning the said sleeve H the box
supported thereon will be moved to one side of the opening between the arms F, F,
accordingly as the sleeve is turned to the right or left.
Thus arranged the box may be elevated or depressed by turning the nut D, or
moved toward either arm F, F, to adjust the shaft, making such adjustment
universal. The box hanging upon the sleeve Hwill oscillate thereon to adapt itself
to the level line of the shaft.
In arrangement for the floor it it will be understood that the preferable mode
would be to invert the parts, making the shank below the shaft, but the adaptation
of the adjusting device to either floor, ceiling, or other places will be understood
from this description.
When it is desirable to remove the shaft it is only necessary to take out the
bolt G, and without disturbing the relative position of the sleeve H in the socket N;
then when the shaft is replaced the sleeve H will return to its previous position
without any change in the position of the box, and consequently re-adjustment of
the shaft is avoided.
The transverse adjustment made by the sleeve H may be used in a hanger
without the vertical adjustment, or with other vertical adjustments than that
described.
In boxes for shaft hangers it is the usual plan to secure the cap to the other part
of the box by bolts or screws, and in such arrangement that the oil used for lubri-
cation works out onto the shaft and drips therefrom, necessitating the hanging of drip
cups beneath the bearing. To avoid the difficulty I pack the ends of the boxes by
constructing the two parts with a screw thread a at each end, and fit to this screw a
packing box or collar fitting over the shaft, and turning on to the threaded ends of
the box with packing between, as seen in Fig. 3, thus making a close joint around
the shaft, and preventing all possibility of drip.
The meeting edges of the two boxes must be formed so that the joint between
them will be tight, and this is best done by making a diagonal joint, as seen at n,
Fig. 2, or a packing may be introduced if preferred.
In order that the packing boxes or collar may be removed from or placed upon
the shaft after the shaft is set they are divided, as seen in Fig. 4, and a horizontal
lock joint e made on each side diametrically opposite each other, and so that a
longitudinal movement of one upon the other will engage or disengage the two
parts, so that they may be held upon or removed from the shaft; but when the
collar is screwed upon the end of the box such longitudinal movement of the two
parts is prevented, and they are held together as one. This locking device may be
variously constructed, it only being essential that they shall be connected together
before being screwed on to the ends of the box, and that such screwing on shall
prevent their separation.
As a means for lubricating the bearing there is made upon the top of the cap one
or more cavities f, in which is set a weighted follower h. The lubricating material
is placed in the cavity f, and the follower holds it down or forces it upon the shaft
to supply consumption.

EDWARD THOMAS HUGHES, of the Firm of Hughes and Son, Patent Agents,
123, Chancery Lane, London. "IMPROVEMENTS IN SHAFT HANGERS." A com-
munication from abroad by Henry Dewey Conc, of Stockbridge, County of Birk-
shire, State of Massachusetts, United States of America.
This Invention relates to improvements in that class of hangers or bearings used
to support shafting employed in the driving or working of machinery, applicable
alike to "overhead," "post," or "floor" supports, the object being to adjust the
bearing after the hanger and shaft are in place, and so that the shaft may be
removed and returned to place without the necessity of re-adjustment, and it
consists in the construction as hereinafter described, and more particularly recited
in the claims.
On the accompanying Sheet of Drawings,—
Figure 1 is a front view; Figure 2, a sectional side view; Figures 3 and 4,
detached views.
As represented in Figs. 1 and 2, the Invention is shown as applied to a post
hanger, and in which A is the plate by which the hanger is secured to the post.
From this an arm B projects outward with a horizontal opening C, or it may be a
pair of arms with a space between, or simply a single arm.
In the open spaco C,
or between the two arms, or on the top of the single arm, a nut D is arranged with
convenient provision for turning, here represented as perforations in the periphery
of the nut. Through this nut a correspondingly threaded shank E is introduced,
and so that by turning the nut, which is stationary, in the direction of its axis, the
sbank E will be raised or lowered accordingly as the nut is turned to the right or
left. Below the support of the nut the crank E is divided to form a pair of supporting
arms F, F. At the lower end of these arms, extending from one to the other, is a
bolt G, and on this bolt is a screw threaded sleeve H arranged so as to be turned
freely on the bolt, but so as to be prevented from longitudinal movement, here shown
as extending from one arm to the other, the two arms forming stops to prevent
such longitudinal movement.
L is the lower part of the box or bearing, and has upon its under side a trans-
verse socket N, screw threaded to correspond to the sleeve H, is introduced before
being placed upon the bolt G, and so that by turning the said sleeve H the box
supported thereon will be moved to one side of the opening between the arms F, F,
accordingly as the sleeve is turned to the right or left. Thus arranged the box
may be elevated or depressed by turning the nut D or moved toward either
arm F, F, to adjust the shaft, making such adjustment universal. The box
hanging upon the sleeve H will oscillate thereon to adapt itself to the level line of
the shaft.
In arrangement for the floor it will be understood that the preferable mode
would be to invert the parts, making the shank below the shaft, but the adaptation
of the adjusting device to either floor, ceiling, or other places will be understood
from this description.
When it is desirable to remove the shaft it is only necessary to take out the
bolt G, and without disturbing the relative position of the sleeve H in the socket N;
then when the shaft is replaced the sleeve H will return to its previous position
without any change in the position of the box, and consequently re-adjustment of
the shaft is avoided.
The transverse adjustment made by the sleeve H may be used in a hanger
without the vertical adjustment, or with other vertical adjustments that that
described.
In boxes for shaft hangers it is the usual plan to secure the cap to the other part
of the box by bolts or screws, and in such arrangement the oil used for lubrication

page_text: works out onto the shaft and drips therefrom, necessitating the hanging of drip
cups beneath the bearing. To avoid this difficulty I pack the ends of the boxes by
constructing the two parts with a screw thread a at each end, and fit to this scrow a
packing box or collar fitting over the shaft, and turning on to the threaded ends of
the box with packing between, as seen in Fig. 3, thus making a close joint around
the shaft, and preventing all possibility of drip.
The meeting edges of the two boxes must be formed so that the joint between
thom will be tight, and this is best done by making a diagonal joint, as seen at n,
Fig. 2, or a packing may be introduced if preferred.
In order that the packing boxes or collar may be removed from or placed upon
the shaft after the shaft is set they are divided, as seen in Fig. 4, and a horizontal
lock joint e made on each side diametrically opposite each other, and so that a
longitudinal movement of one upon the other will engage or disengage the two
parts, so that they may be held upon or removed from the shaft; but when the
collar is screwed upon the ond of the box such longitudinal movement of the two
parts is prevented, and they are held together as one. This locking device may be
variously constructed, it only being essential that they shall be connected together
before being screwed on to the ends of the box, and that such scrowing on shall
prevent their separation.
As a means for lubricating the bearing thero is made upon the top of the cap ono
or more cavities f, in which is set a weighted follower h. The lubricating material
is placed in the cavity f, and the follower holds it down or forces it upon the shaft
to supply consumption.
Having now described the construction and operation of the said Invention, I
would observe in conclusion that I do not claim an adjustable hanger, but what I
do claim as the Invention is,―
First. In a shaft hanger the combination of the box which forms the bearing
constructed with a transverse screw threaded socket, a transverso correspondingly
threaded sleeve stationary in the direction of its axis, but so as to be rotated thereon,
and a support for said sleeve, substantially as described.
Second. In a shaft hanger the combination of the box which forms the bearing
constructed with a transverse screw threaded socket, a transverse correspondingly
threaded sleeve stationary in the direction of its axis, but so as to be rotated
thereon, a screw threaded shank at right angles to and carrying said sleeve and box,
with a correspondingly threaded nut supported stationary in the direction of its
axis, substantially as and for the purpose described.
Third. In a bearing for shafting the combination of the two parts of the box
screw threaded at each end with a collar correspondingly threaded, substantially as
and for the purpose described.
Fourth. In a bearing for shafting the combination of the two parts of the box screw
threaded at the two ends and a collar correspondingly threaded made in two parts,
interlocking with each other by a longitudinal movement, and secured by the said
screw threads, substantially as described.
Fifth. In a bearing for shafting the cap or upper part of the box, constructed with
one or more lubricating cavities, combined with a follower arranged in said cavity,
and substantially as described.
In witness whereof, I, the said Edward Thomas Hughes, have hereunto set my
hand and seal, this Fourth day of September, in the year of our Lord One
thousand eight hundred and seventy nine.
