PROVISIONAL SPECIFICATION.
Improvements in Adjustable Hangers, Brackets, and other similar
Adjustable Supports for the Bearings of Shafting and the like..
I, FREDERICK LISTER CROFT, of Lower Ernest Street, Bradford, in the
County of York, Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in adjustable hangers, brackets and other:
similar adjustable supports for carrying the bearings of shafting or the like and its
object is to provide simple, cheap and efficient means of adjustment.
For this purpose I form the usual cylindrical socket or sockets in the hanger,
bracket or the like adapted to receive an adjustable cylindrical piece or pieces to
support the bearing as in the ordinary manner. But to adjust these cylindrical
pieces axially in the said sockets I employ a screw stud projecting from the bottom
of each socket arranged to engage a female screw thread formed in axial holes in
said cylindrical pieces. Thus by turning the cylindrical piece or pieces upon
Baid stud or studs it or they may be adjusted further in or out of the socket or
Bockets.
The said stud may be fixed by a couple of nuts in a concentric hole through the
bottom of the socket or in any other convenient manner.

COMPLETE SPECIFICATION.
Improvements in Adjustable Hangers, Brackets, and other similar
Adjustable Supports for the Bearings of Shafting and the like.
1, FREDERICK LISTER CROFT, of Lower Ernest Street, Bradford, in the,
County of York, Engineer, do hereby declare the nature of this invention and
5 in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to improvements in adjustable hangers, brackets and other
similar adjustable supports for carrying the bearings of shafting or the like and its
object is to provide simple, cheap and efficient means of adjustment.
For this purpose I form the usual cylindrical socket or sockets in the hanger,
bracket or the like adapted to receive an adjustable cylindrical piece or pieces to
support the bearing as in the ordinary manner. But to adjust these cylindrical
pieces axially in the said sockets I employ a screw stud projecting from the bottom
of each socket arranged to engage a female screw thread formed in axial holes in
Baid cylindrical pieces. Thus by turning the cylindrical piece or pieces upon
said stud or studs it or they may be adjusted further in or out of the socket or
sockets.
The said stud may be fixed by a couple of nuts in a concentric hole through the
bottom of the socket or in any other convenient manner.
Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification, in which similar letters of reference indicate corresponding parts
in each of the figures.
:

page_text: Figure 1, represents an elevation of a bearing pedestal constructed in accordance
with my invention.
Figure 2, represents a plan view of the same.
Figure 3, represents a diametrical section of the upper cylinder and socket on
the broken line a, b Figure 2.
Figure 4, represents a similar section of the lower cylinder and socket.
The pedestal is of the usual form but its upper socket A is fitted with an internal
concentric stud B fixed in the hole C in the top of the socket by the nuts D
and D' on said stud, respectively bearing against the upper and underside of said
hole. The stud B is cut with a screw thread from end to end to fit the female
thread cut in the upper end of the cylindrical piece E. By this.construction it is
simply necessary to turn the cylinder on the stud in one direction or the other to
adjust it up or down as required to adjust the bearing F and shaft G carried
between this cylinder and the lower cylinder E'. The lower cylinder is also
mounted in a socket A' upon the stud B³in a similar manner to the upper cylinder
and is adjusted in the same way. But as in a pedestal it is not desirable for the
stud to project below it may be formed with a head or disc H at the base lying in
the recess J formed in the underside of the pedestal and large enough to allow two
or more screws K to be passed through into the top of J to secure the stud in
position. Holes R may be formed in the cylindrical pieces adapted to receive the
end of a lever to facilitate turning said pieces.
It is obvious that the stud may be fixed in various other ways and that in case
of a hanger both the upper and lower studs may be fixed in the same way. In any
case a set screw L is preferably fitted by which the cylindrical piece may be rigidly
clamped in its socket.
Having now particularly described and ascertained the nature of my said inven-
tion, in what manner the same is to be performed, I declare that what I
claim is:
1. A cylindrical bearing support fitting a socket provided with a concentric stud
having a male screw thread thereon engaging a female screw thread formed in
said bearing support, substantially as herein shown and described and for the purpose
specified.
2. The combination with the socket provided with a concentric screw stud, of
the cylindrical piece having a screw thread to fit said stud and a set screw or
equivalent device adapted to clamp said cylindrical piece in said socket,
substantially as herein shewn and described and illustrated in the accompanying
drawings.
