Improvements in Bolsters or Bearings for the Spindles of Spinning,
Doubling, and like Machinery.
We, WILLIAM HARDCASTLE, of 6, Bell Street, Newsome Road, Huddersfield,
Yorkshire, Mill Manager, and JAMES FOX HARDCASTLE, of 15, Bell Street, Newsome
Road, Huddersfield, aforesaid, Cotton Twiner, do hereby declare the nature of
this invention to be as follows:-
This invention has reference to bolsters or bearings in which are journalled the
spindles of spinning, doubling and other like machinery in which spindles
are employed and our improvements consist in modifying the construction of said
bearings or bolsters in such manner that friction will be reduced to a minimum
whereby the spindles will run much lighter and a saving in power and wear and
tear be effected.
In carrying out our invention we construct the bolster proper in two sections
one of which is secured to the bolster rail or board of the machine while the
second one is secured to the face or in front of the other. The first section, pre-
ferably, has three sided openings formed through from top to bottom and the mid-
portion of the section made hollow or provided at top and bottom with flanges
in order to receive the second section, though this may not be material. The
said openings are made at equal distances apart corresponding to the distance
apart of each spindle and they are either cut to the angle the spindles assume
or the section itself is brought to the corresponding angle against the bolster
rail. The second section of the bolster is provided at distances apart corresponding
to the openings aforesaid with projecting curved bearing surfaces so that when
the second section is secured to the first section the openings to receive the spindles
assume a D shape. When journalled in the bearings or bolsters provided as set
forth the spindles only touch the bearing surfaces at three points, one on each side
and the third at the back or on the same side as the pull of the bands on the
spindle, the opposite or front side of the spindle being supported and kept in
position by the curved surface on the outer or second section.
We may, however, secure a plain strip or bar to the bolster rail in place of the
first section above described and form openings having two sides straight and one
curved in the second section which will be secured to the face of the strip or bar
the latter giving the third straight side required. In the front of each bolster or
bearing is formed a slot or groove in order to enable those in attendance to oil
the whole of the bearings while the machine is in motion, a brush, tape, or
saturated cloth being used for the purpose, or the lubricant may be supplied by
its own gravity.
The front or second section of the bolsters or journals is made in suitable lengths
so as to be easily removeable for any purpose such as when taking out or replacing
a spindle, the withdrawal of said section allowing any spindle or spindles to be
lifted straight out and placed back again both easily and expeditiously.
By mounting spindles in journals or bolsters constructed as above described,

required, while the heat engendered by constant friction is very considerably
reduced.
Improvements in Bolsters or Bearings for the Spindles of Spinning,
Doubling, and like Machinery.
We, WILLIAM HARDCASTLE, of 6, Bell Street, Newsome Road, Huddersfield,
Yorkshire, Mill Manager, and JAMES FOX HARDCASTLE, of 15, Bell Street, Newsome
Road, Huddersfield, aforesaid, Cotton Twiner, 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:-
This invention has reference to bolsters or bearings in which are journalled the
spindles of spinning, dombling, and other like machinery in which spindles
are employed, and our improvements consist in modifying the construction of said
bearings or holsters to secure lighter running, free and thorough lubrication and
to enable any spindle to be removed without disturbing the others whether the
machine be in motion or standing.
In carrying out our invention we construct the bolster in two sections
one of which is secured to the bolster rail or board and the other secured to the
face of or in front of the first named section. In new machinery, or in applying
new bolsters to old machinery, the section of the bolster which is secured to the
bolster rail is provided at the front with openings forming three sides of a square
in which the spindles will fit nicely and only touch the sides thereof at three
points of its circumference. The front plate, when secured to the face of the
bolster, forms the fourth side of the openings and completes the bearings.
Slots or openings are cut or formed in the front plate opposite each bearing so
as to expose a portion of same and of the spindles to allow of lubricant being
supplied thereto at any time and while the machine is in motion. The front plate
is made in short lengths which can be readily removed singly and a spindle or
spindles taken out without stopping the machine or disturbing the neighbouring
spindles.
The front or rear sides of the square bearings may be slightly curved if desired.
In applying our improvements to old bearings of round section we cut away the
front side thereof and then cover the openings thus made by the front plate above
described, suitable strips of packing or ribs or extensions being provided inter-
mediate of the bearings to hold the front plate in the required position to form
the front side of the bearings.
In order that our said invention may be fully understood, reference is here-
after had to the annexed drawings forming a part of this Specification, in which:
Fig. 1 is front elevation of a portion of the carriage of a self acting mule, shew-
ing the application of our improvements.
Fig. 2 is plan view of Fig. 1 taken on line 1, 2.
Fig. 3 is a similar plan view shewing our improvements as applied to old or
round bearings or bolsters.
Fig. 4 is enlarged transverse section of the bolster or bearing shewn in Figs. 1
and 2.

described and for purposes set forth.
Secondly. The combination, with spindle bolsters or bearings of square angular
or round section having one side open or cut away, of a detachable plate or
plates, such as 9 adapted to be secured to or in front of said bolsters or bearings
and provided with transverse openings or slots such as h and a longitudinal groove or
channel or channels i, all arranged in the manner and for the purposes substan-
tially as herein shewn and described.

page_text: Referring to the drawings, letter a represents the bolster rail or board, to the
front of which is secured by screws or like means a bar or rail 6 composed of brass
or other suitable metal or material. In the front side of said rail 6 are
formed or cut at equal distances apart, vertical openings c forming three sides of
a square or the said openings may be angular wherein are journalled the spindles d
which rest in footsteps on the bottom board e of the carriage as ordinarily. To
the face of the rail b is attached by screws for like means a plate 9 which forms
the fourth or front side of the bolsters or bearings c and secures the spindles in
their bearings. In the said plate 9, opposite each bearing, are formed openings h
which expose a portion of each bearing and spindle, such openings preferably
being located at the back of a longitudinal groove or recess i formed in the face
of the plate somewhat as shewn, this groove acting as a guide along which the
spout of an oil can can be drawn to lubricate each bearing and spindle, any
lubricant lodging in the bottom of the groove i being conducted thereby to the
openings h. The front plate g is, by preference, made in short lengths, in order
that they may be easily removed when desiring to take out or replace any spindle,
the withdrawal of a length of said plate allowing any spindle in that section to
be lifted straight out of the machine, whether it is in motion or otherwise, and
placed back again expeditiously, and without disturbing any of the neighbouring
spindles. We prefer to employ square journals as seen at Fig. 2, for the reason
that the frictional surface with which the spindles are in contact is greatly
reduced and lighter running is therefore obtained and wear and tear very much
reduced, and the bolsters or bearings are kept quite cool.
When applying our improvements to the present round bolsters either old or
new, and single or formed in a rail similar to that shewn at Figs. 1 and 2, we
cut away a portion of the front side of each bearing or bolster 6 from top to
bottom and secure the plate g to the front of the bolster rail or board a, as shewn
at Fig. 3, to form the front bearing surface, and to secure the spindles in their
bearings.
As the plate g must be held at a short distance away from the front of the cut
bolsters to give the full diameter or area of bearing required, pieces of packing,
or ribs or extended surfaces are provided intermediate of each bearing, or the
same result could be obtained by providing the plate 9 with a curved surface
opposite each bearing. The plate g is provided on the face thereof with a longitu-
dinal groove i and with slots or openings h for exposing a portion of each bearing
and spindle to admit of lubrication of same, as previously described with reference
to Figs. 1, 2 and 4. The method set forth of lubricating the spindles, in addition
to facilitating the work and enabling it to be done at any time whether the
machine is in motion or not, also entirely avoids the danger of the lubricant
reaching the bases of the caps built upon the spindles or of being deposited
thereon when lubricating.
The improved bolsters or bearings above described may be applied to spindles
in any class of machine in which the spindles are so arranged as to admit of said
bolsters or bearings being used with advantage.
The precise construction and arrangement of the bearings or bolsters and plate g
with the oil inlets therein may be varied or modified as found best suited to
the particular machine or mounting of the spindles to which they are applied
without departing from the main features of our invention.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what we
claim is:-
Firstly. The combination, with square angular or circular spindle bolsters or
bearings open on one side, of a detachable plate or plates attached to or in front
of same to form the remaining side or portion of the bearings and secure the
spindles therein, said plate or plates being provided with openings or slots to expose
