JOSEPH SAMUEL TAYLOR and STEPHEN WILLIAM CHALLEN, of the Derwent
"AN IMPROVED
Foundry, Birmingham, in the County of Warwick, Engineers.
COMBINATION SHAFT BRACKET WITH BEARING, ADJUSTABLE AND SELF-ADJUSTING,
APPLICABLE AS HANGERS AND WALL BRACKETS, PEDESTALS, AND BEARING BLOCKS,
AND DESIGNED FOR CARRYING Line, Single, AND OTHER ROTATING SHAFTING OR
SHAFTS."
The nature of our Invention, relating to the construction of brackets and bearings
for line and other rotating shafting and shafts, consists in their capability of
adjustment after the soles or bed plates of such brackets have respectively been
durably fixed in a line, without much regard to precision, to the underside of beams
or floors in the position of hangers, to walls as projecting brackets, upon floors as
pedestals, and in other positions and places.
Our object is to provide a shaft bearing in combination with such bracket, tho
true lineal arrangement whereof does not depend as heretofore on the accuracy with
which the sole or bed plate of the bracket is permanently fixed to or upon its seat
or bed. This being otherwise accomplished by our Invention, we are enabled to
save nearly all the expenso for skilled labor and valuable time of the workmen,
which the tedious operation of fixing and setting in the ordinary manner line and
other shafting alway entails. The true lineal position of a series of our bearings is
with the utmost precision capable of being regulated subsequently by adjusting

page_text: screws, assisted by a tendency in each bearing to adjust or bed itself to the true
axial line of the shaft.
Our Invention may be advantageously employed in all mills, factories, work-
shops, and places were line shafting and single or other shafts are employed. Also
where power is used in mining and engineering operations, for contractors' work
generally, and in all cases where the frequent shifting of bracket blocks and beams
is indispensable, and new adjustments are constantly required according to the rato
of progress of the work. Our new combination bracket and bearing consists of two
adjusting screw bolts with lock nuts, and three other principal parts (viz.). The
base or bracket piece which carries the bed or sole plate; the bearing proper or
piece that supports the shafting; and the adjustable extension piece which form the
connection between the other two.
The base or bed plate of the bracket piece is as usual furnished with holes
for the reception of the bolts commonly employed to fix it firmly to the underside
of beams when used as a hanger; to the surfaco of walls when used as a bracket;
or upon floors when used as a pedestal, the parts combined answering for all such
purposes. Two strong spurs respectively either curved or straight are cast on the
upper surface of the base plate. They spring from the face of the plate respectively
at or about a right angle near the ends, and thence inclining one towards the other
meet exactly over the centre of the base plate in the form of either an arch or a
gable. The free or meeting end of each spur has the form internally of a semi-
circular groove, so that the two together form a coupling, and each is laterally
provided externally with lugs for cramping bolts. This coupling is vertically bored
out to receive the straight end of the adjustable extension piece, which is turned
and finished to a corresponding size.
The extension piece forins the adjustable connection between the base or bracket
piece, and the part which carries the shaft bearing or bearing proper. The
extremity of its straight end is T-slotted crosswise to receive the flat round head
of one of the adjusting bolts. The other end of this bolt screws into a threaded
hole drilled through a boss cast on the centre of the base plate in a direct line with
the axial centre of the coupling, and by means of this screw bolt the straight end
of the extension piece is caused to slide longitudinally in the coupling, according to
the direction in which the screw is turned, so as either to draw it inwards towards
the plate, or force it out in the contrary direction. The other or longest portion of
the extension piece is suddenly cranked to a right angle, and then takes the shape
of a quadrant. On its extreme end it carries a half split boss which is cast on and
provided with lugs to receive a cramping scrow, and also a bridge piece to receive
the end and engage with the other adjusting screw. This half split boss is so
placed and bored out that its axial line intersects the diametral plane of the
straight end of the extension piece.
The bearing proper is cast or otherwise fixed (by preference at an anglo of 45°)
on the end of a strong shank that is turned to fit and slide in the half split boss on
the end of the extension piece, the extreme end of the shank being like the straight
end of the latter piece also T-slotted crosswise for the reception of the flat round
bead of the other adjusting screw bolt.
By this means (it will be seen that in the case of a hanging bracket) the vertical
adjustment of the extension piece is effected by the adjusting screw that engages
in the base plate, and the horizontal adjustment of the bearing proper is regulated
by the screw that engages in the bridge piece, and moves the shank with the
bearing proper in a direction at right angles to the line of shaft, and until the
cramping screws are tightened up, all the several bearings of the series that carry a
line of shafting have full liberty in all directions fairly to bed themselves to the
shaft.
Some of the advantages derivable from the use of our new combination bracket
bearing embraco the expeditious fixing of the bracket base plates, which, as no
special exactness is required, is very quickly accomplished, and consequently the great
saving effected in the cost of skilled labor is very considerable, besides avoiding all

page_text: slack bolts, or necessity for the use of packing. An uniform pressure always
existing between that portion of the shaft which rests in the bearing throughout
the length of the latter in consequence of its ability to adjust itself, results in less
wear, less oil consumed, and smooth running with less power. Another great
advantage consists in being able at any future time without disturbing any of the
base plates or the screws whereby they are held, to readjust the level or lineal
truth of a line of shafting, if in consequence of the subsidence of foundations, the
loading of floors, or from other causes it has suffered derangement.
We make the coupled shaft bearings proper of our combination bracket either
of solid metal bored out to the size of shaft, or we fit them internally with
bronze or bell-metal couplings, line them with metaline, or otherwise mount them
according to any or all of the numerous ways known to mechanics and engineers,
the style of the bearing employed and the mode of fitting it being in most cases
dependent, more or less, upon the nature, weight, and intended speed of the
rotating shaft.

by the said Joseph Samuel Taylor and Stephen William Challen in the Great
Seal Patent Office on the 13th August 1880.
JOSEPH SAMUEL TAYLOR and STEPHEN WILLIAM CHALLEN, of the Derwent
Foundry, Birmingham, in the County of Warwick, Engineers. "AN IMPROVED
COMBINATION SHAFT BRACKET WITH BEARING, ADJUSTABLE AND SELF-ADJUSTING,
APPLICABLE AS HANGERS AND WALL BRACKETS, PEDESTALS, AND BEARING BLOCKS,
AND DESIGNED FOR CARRYING LINE, SINGLE, AND OTHER ROTATING SHAFTING OR
SHAFTS."
The nature of our Invention, relating to the construction of brackets and bearings
for line and other rotating shafting and shafts, consists in their capability of
adjustment after the sole or foot plates of such brackets have respectively been
permanently fixed in a line, or otherwise, without much regard to precision, either
to the side or underside of beams, or of floors in the position of hangers, to walls,
pillars, or columns as projecting brackets, upon floors as pedestals, and in other
positions and places, the bearings of such brackets having sometimes formed withia
them, in the usual way, a cavity to contain a liquid lubricant which, by well-
known means, is supplied to the frictional surfaces both mechanically and by
capillary attraction.
Our object is to provide, in combination with such brackets, a shaft bearing,
either furnished with soft metal coupled linings, and self lubricating when required,
or a plain hored bearing, the true lincal arrangement whereof does not so much
depend as heretoforo upon the accuracy with which the sole or foot plate of the
bracket is permanently fixed to or upon its scat or bed. The necessary adjustment
being afterwards accomplished by the adjustability of the bearing, we are enabled
to save nearly all the expense for skilled labour and valuable time of the workmen
which the tedious operation of fixing, levelling, and setting in the ordinary manner
line and other shafting always entails. The true lineal position of a series of our
bearings is, with the utmost precision, capable of being regulated subsequently by
adjusting screws, assisted by a tendency in each bearing to adjust or bed itself to
the true axial line of the shaft. And, what is very important after adjustment,
the parts of the bracket are, by means of cramping bolts, so secured in their
adjusted position as to be made quite as immovable and rigid as they would be if
the separate parts of the bracket and bearing were all cast in one piece.
Some of the many advantages derivable from the use of our combination bracket
bearing embrace the expeditious fixing of the foot plates of the bracket base piece
which, as no special exactness is required, is very quickly accomplished, and con-
sequently the saving in the cost of skilled labour is very considerable, beside the
avoidance of all slack bolts or necessity for the use of packing. Also a uniform
pressure always existing between that portion of the shaft which rests in the
bearing throughout the length of the latter in consequence of its ability to adjust
itself, results in less wear, less oil consumed, and smooth running with less power,
particularly in the case of those bearings which are provided with a self-lubricating
appliance. Another great advantage consists in being able, at any future time
without disturbing any of the base plates or the screws whereby they are held, to
readjust the level or lineal truth of a shaft or a line of shafting if, in consequence of
the subsidence of foundations, the over-loading of floors, or from other causes it has
suffered derangement.
Our Invention may be advantageously employed in all mills, factories, workshops,
and places where line shafting and single or other shafts, whether horizontal,
vertical, or diagonal, are required. Also where power is used in mining and
engineering operations, for contractors' work generally, and in all cases where the

page_text: frequent shifting of bracket beds, blocks, and beams is indispensable, and new
adjustments are constantly required according to the rate of progress of the work.
Our new combination bracket and bearing consists of three principal parts (viz.).
The base or bracket piece which carries the foot or sole plate; the bearing proper
which receives and supports the shaft; the adjustable extension swivelling piece
which is interposed and connected at one end to the bracket base piece, and at the
other end to the bearing. These parts in collective relation to each other are
capable of being adjusted by two suitable or special adjusting screws, and by means of
cramping bolts subsequently they can be fixed in a variety of positions respectively
suited to carry either horizontal, vertical, or diagonal shafting, although the
foot or sole plates of the brackets be fixed as may be most convenient, either to an
overhead beam, the surface of a wall, to a pillar or column, or upon a floor, and it
is this general power of adaptation in addition to its many other advantages
that, we believe, gives to our Invention a pre-eminence that will soon become
established.
We will now proceed (in the first place) to describe and show the construction
of our adjustable combination bracket bearing according to our primary arrangement
and configuration of the several parts; in the second place we will describe and
show divers arrangements of our bracket bearing, wherein respectively one or more
of the parts are modified in configuration, the adjusting screws in some cases being
also modified in form and variously applied; and in the third place we will describe
and show some of the various positions and adaptations to which our Invention
can be advantageously applied. In cach case we make reference to the one or
other of the Figures on the Drawings hereto annexed, and the letters and digits
used in our description to distinguish the several parts and details will be found to
agree with the letters and digits marked on the corresponding parts and details as
shown on the Drawings by the several Figures thereon, that is to say.
The primary arrangement of our bracket bearing is exhibited on Sheet 1, Fig. 1
being a front view of the several parts in combination; Fig. 2, a side view of the
bracket affixed to a wall; and Fig. 3 is a plan view of the same.
The sole or
foot plate A' of the bracket base piece A is, as usual, furnished with holes for the
reception of the bolts employed to affix it firmly to beams, walls, pillars, or floors,
it being shown in this case as a bracket affixed to a wall. Two strong curved
spurs forming a part of the bracket base piece A are cast upon the upper surface
of the sole plate A They spring from the face of the plate respectively
at or about a right angle near the ends, and thence inclining one towards
the other in the form of an arch, meet exactly over the centre of the base
plate. The free or meeting cud of each spur has the form internally of a seini-
circular groove, so that the two ends (which do not unite) form a cramping
coupling marked A³, and cach is laterally furnished externally with A³, which
marks two projecting lugs that have holes for the reception of two cramping
bolts marked A'. This coupling in our best brackets is vertically bored out
to receive the straight end marked B' of the adjustable extension swivel piece
B, which end is turned and finished to a corresponding size so as to be capable
of rotating and sliding endwise in the coupling. The extension piece B forms the
adjustable connection between the bracket base picce A, and the adjustable part A¹
that carries C, which marks the shaft bearing. That portion which adjoins the
straight end of the extension piece B is suddenly bent or cranked to a right angle,
and thence it takes the shape more or less of a quadrant. On its extreme outer end it
has (cast in one piece with it) a split boss marked B2, which boss carries B³ that
marks two lugs, one lug being placed on one side and the other on the opposite
side of the split part of the boss, and both have corresponding holes to receive a
cramping bolt, marked B'. A small projecting bracket B is also cast on the outer
end of the extension piece to carry one end of D, which marks the screw that
adjusts the projecting shank C₁ of the bearing proper C. The shank C₁ of the
bearing of our best brackets is also lathe turned to suit the internal size of the split
boss B³, which is so placed on the extension piece and bored out that its axial line

page_text: intersects at a right angle the axial line of its straight end B'. The shaft bearing
proper C is by preference cast in one piece with its shank C¹, and at an angle
therewith of about 45°. C' marks the metallic linings of the bearing; C³, the cap;
C', the cap screws, and C³ oil passages.
Fig. 4, D marks the adjusting screw that regulates the longitudinal position of
the straight end of the extension picce in the cramping coupling A² of the bracket
base piece. The lower end of this screw is seen to be firmly confined in a hole
made in the centre through the sole plate A¹, but it has liberty to rotate; the
other end of the screw is screw-threaded and furnished with a lock nut; it is
screwed into a threaded hole concentrically made in the straight end of the
extension piece, and according to the direction in which the screw is turned will
draw the extension piece either up or down, or inwards and outwards, as may be
required to effect (in the case of a wall bracket) the lateral adjustment of the
bearing C, the vertical adjustment whereof is effected by the screw E (Fig. 5), the
plain end of which is firmly secured with liberty to turn in a hole made through
the small bracket piece B³ in the direction of the end of the bearing shank C¹, in
which there is a threaded hole made to receive the opposite end of the screw E,
which is screw-threaded to correspond, and by this means the shank of the bearing
is moved endwise in either direction and the vertical or levelling adjustment of the
bearing is thereby effected. When however our combination bracket is fixed to
the underside of an overhead beam the vertical or levelling adjustment is effected
by the screw D, which then moves the extension pieco either up or down, and the
lateral adjustment is then effected by the screw E. After the lineal adjustment
of the line of shafting is complete and the several bearings have separately bedded
themselves to the shaft the nuts on the cramping bolts of the coupling A² and of
the split boss B³ respectively are thoroughly tightened up, so as to cause the
cramping coupling to grip the end B' of the extension pieco and the split boss to
grip the shank of the bearing so forcibly that the whole of the parts combined are
immovably secured in their adjusted position, and so that they are held as rigidly
as if they consisted only of one piece. Knowing however that constant dropping
will wear away stone, so we believe that the constant jarring and rattling of tooth
wheels might in time alter the adjustment, we therefore as an additional security
in the case of those brackets that are placed contiguous to tooth gearing pass steel
dowls or keys or steady screws through the parts held by the cramping bolts.
The several details and parts of our combination bracket bearing are shown
separately on Sheet 1 by the following Figures (viz.):-Figs. 6 and 7 exhibit
respectively a plan and a front view of A, which marks the bracket base piece,
A' being the sole or foot plate, A² the cramping coupling, and A³ the lugs for tho
cramping bolts; Figs. 8 and 9 show respectively a side view and an end view of
B, the extension swivel piece, B¹ marking the straight end, B³ the split boss, B³
the cramping luge, and B the small bracket piece; Figs. 10 and 11 respectively
show a side view and a plan of our bracket bearing C, the body of which is made
in one casting with C', which marks the shank, C² the metallic linings, C³ tho cap,
C' the holes for cap screws, and C5 oil passages.
Figs. 12, 13, and 14 exhibit respectively a side view, an underneath view, and
an end view of our bracket bearing adapted as a hanger secured to the under
surface of an overhead beam, and arranged for carrying one end of a counter-shaft,
the strap guide support being attached to the bracket bearing. This bracket is
the same in most respects as that already described with reference to the Figs. 1,
2, and 3, excepting that no adjusting screws are employed. A (as before) marks
the bracket base piece, which is the same in form with sole plate A' and cramping
coupling A. As before, B marks the extension swivel piece, B' its straight end,
and B the split boss, the small bracket piece being dispensed with. C marks tho
shaft bearing, which in this bracket is shown to be a plain bored out boss cast
with a shank C¹. The annular clip F is fastened on one end of the bearing by
incans of a screw bolt F¹. The outer end of F, which marks the projecting arin of
the clip, has the form of a chain link made so to receive F3, which marks a small

page_text: pulley, the axle whereof F finds a bearing in two plain holes made respectively
coincident in the opposite sides of the link-formed end of the clip, the pulley filling
up the space between. A certain length at the end of the axle is screw-threaded
externally, and the hole through the centre of the pulley is screw-threaded to
correspond. The periphery of the pulley is formed with recesses to receive an
endless chain, marked F5, which chain hangs from the pulley in the form of a long
loop. When the chain is pulled on either side it causes the pulley to rotate, and
the pulley being confined between the sides of the link-formed end of the arın of
the clip, by means of its internal screw effects the necessary longitudinal movement
of the axle, to which the bar which carries the strap guides F is welded. Figs. 15
and 16 respectively show a side view and an end view of the plain shaft bearing C
with its shank C', and Figs. 17 and 18 show two views of the extension picce B
minus the small bracket piece.
Figs. 19 and 20 represent respectively a transverse section and a longitudinal
section of one of our best class shaft bearings C, cast with a shank C', showing
the shaft C, the oil cavity P, and the endless cotton wick feeder Q. This mode of
self-lubrication however forms no part of our present Invention, and all the
novelty we shall hereafter claim in respect thereof consists in casting in one piece
or conjoining the body piece of a self-lubricating shaft-bearing with or to an
adjustable shank.
It will now be seen that wo make the shaft-bearings of our combination adjustable
brackets (in order to meet all requirements) sometimes cylindrical or of solid metal,
being simply bored out to the size of the shaft (as described with reference to
Figs. 12 and 15), but generally we furnish them internally with bronze or with bell-
metal coupled linings, or with metalline plugs, or otherwise mount them according
to any or all of the numerous ways known and practised by mechanics and by
engineers, the size and strength of the bracket and parts, the style of the bearing
employed, and the manner of fitting it being more or less dependent upon the nature,
weight, and intended speed of the rotating shaft, and the limit by which we are
compelled to regulate the cost.
Figs. 21 and 22 represent two views of a bracket piece designed for attachment
to the side of a beam; and Figs. 23 and 24 two views of another form of bracket
pieco designed for attachment to the underside of a beam. Both of these bracket
pieces are furnished with our split bosses B for holding and cramping the adjustable
end B¹ of the extension piece B; or when the latter (for want of room or from any
other cause) is omitted, the shank of the bearing C, such forms of bracket pieces
being used occasionally when a line shaft runs close beneath or alongside a beam ;
but in cases where a shaft or a portion of line of shafting runs a considerable distance
from a beam to which we desire to affix a bracket we employ a long bracket piece,
such as is shown by Figs. 25 and 26, which: respectively represent a side and an
edge view. This bracket piece, it will be seen, is also furnished with our split
boss B, wherein the straight end of an extension picce, when the bracket pieco is
fixed, may be inserted either at the upper or the underside of the split boss, and by
this means any reasonable distance or position of the shaft may be reached.
Sheet 2. On this Sheet of Drawings we show by one or more of the different
Figures thereon the several modifications herein before mentioned as relating
chiefly to changes in the configuration of two of the principal parts (viz.), the
bracket pieco A and the adjustable extension swivelling piece B, the bearings C
being (with one exception) in all the other inodifications furnished with an adjustable
shank.
Figs. 1 and 2 show in a modified form one of our combination bracket bearings
adapted as a hanger depending from a beam. In this modification the bracket base
piece is solid, and as usual is furnished with a sole plate A' and two projecting
lugs marked A³, one being cast at each side of its outer end As, which is made
hollow like a half-bearing to receive and form a bed for the adjustable portion B¹
of the -formed extension pieco B, which (sco Fig. 2) is held in its place by G,
that marks a staple-formed cramping bolt, screw-threaded and furnished with a nut

page_text: at each end. The extension piece of this bracket is provided with a split boss B'
to receive the shank C¹ of the bearing C, which is mounted with coupled linings
and capped, the cap and the linings being respectively held in place by one hook-
headed bolt marked H, the other end of this bolt being screw-threaded and furnished
with a nut for tightening up. The cap C³ is provided with a transverse recess to
receive the hooked head of the bolt H, by which means the cap is kept in position
endwise, and for a similar purpose the ends of the linings respectively are provided
with small projecting nibs (see Fig. 1) that prevent them sliding endwise or turning
with the shaft. The two adjustments of this bracket (vis.), of the extension piece
and of the shank of the bearing respectively, are made by means of duplex adjusting
screws marked J, both ends of which screws are screw-threaded, and provided with
nuts. These duplex screws carry, laterally projecting at their midlength, a small
square nib J¹ that is designed for entering an annular recess J* formed in the
adjustable part of the extension piece. The duplex adjusting screws are disposed
in grooved recesses formed, as shown, in the solid or the stationary parts respectively
of the bracket base piece and the split boss of the extension piece, but so contiguous
to the parts to be adjusted (see Fig. 15) that the projecting nibs of the screws enter
the annular recesses respectively of the said parts. These duplex screws may be
used in any of the modifications hereafter to be described, and also in the brackets
already described and exhibited on Sheet 1. After adjustment the parts are main-
tained in permanent position (viz.), the extension piece adjustment (which in this
case is horizontal) by the thorough tightening up of the nuts on the ends of the
staple-formed cramping bolt G, and the shank of the bearing by the cramping bolt
of the split boss B₁ on the extension piece. Figs. 4 and 5 show the half-bearing of
the base piece of this bracket, placed in a different position to that shown in Figs. 1
and 2, and which in some cases is preferable; Figs. 6, 7, and 8 show three separato
views of the extension piece of this bracket in its modified form, and furnished
with a split boss having lugs and a cramping bolt.
Figs. 9 and 10 represent the second modification of our bracket bearing, the parts
A and B being further changed in configuration but similarly arranged. On referring
to the Drawing it will be seen that the bracket base piece A is a solid block cast on
the sole plate A¹, by which it is affixed to an overhead beam (as shown), but may
be disposed otherwise. It carries a split boss placed horizontally, and is furnished
with lugs for cramping bolts, the whole being cast in one piece. The extension
piece B of this modification will be seen to have another form that enables its
adjustable end B' to enter horizontally the split boss B³ of the bracket base piece,
so as to bring the centre of the split boss which it carries coincident at a right
angle with the axial line of its adjustable end. A plain bored out bearing C with
shank vertically disposed is shown combined in this modification, but it will be
understood with regard to this, as in most of the other modifications, that any of
the shank bearings that have been or have to be described may be adapted thereto.
The adjustments in this bracket bearing are effected by two of the duplex adjusting
screws already described with reference to Figs. 3 and 15.
Figs. 11, 12, and 13 represent three views of a 7-formed extension piece B
made in two parts, fixed together by a bolt that is seen to pass lengthwise through
the adjustable part, and by this means an extension piece of this form may be
employed either with a cramping coupling or a split boss. The two free ends form
a cramping coupling to receive and secure the shank of a bearing after adjustment,
for which latter purpose a duplex screw J is shewn.
Figs. 14, 15, and 16 represent our third modification, which is presented as a
hanging bracket, the base piece A of which has the form of a truncated tube, one
end whereof is centrally cast to its sole plate A', and at a right angle projects
therefrom an annular recess, being formed round the tube to receive the nib J of a
duplex adjusting screw J. Formed on each of the ends respectively of the extension
piece of this modification there is a kind of half-bearing, marked respectively Aº
and A7, the former being adapted to one side of the truncated tube or base piece A,
and the latter to the shank of the bearing, the body part of the extension piece B

page_text: being so quadrantally curved that the half-bearings stand relatively one at a right
angle to the other, and both of them are furnished with two lugs, one lug on each
side, and bored for the reception of the screwed ends of staple-formed cramping
bolts G, there being two of these bolts to each. By means of these half-bearings
and cramping bolts the parts of the bracket are held in position during adjustment,
which (as shown in the Drawings) is effected by two duplex adjusting screws,
respectively disposed in grooves in the half-bearings and made therein for their
reception. The bearing of this bracket may be either one of our best lined or ono
of the simplest and cheapest kind, as shown in the Drawing, but whichever is used
its shank must have an aunular groove made round it to receive the nib of tho
duplex adjusting screw. After the adjustment is complete the nuts on the end of
the staple-formed cramping bolts respectively are thoroughly tightened up, and by
means of this powerful grip the parts of the bracket are immovably fixed in the
adjusted position.
Fig. 17 shows a simple contrivance for adjusting the round end of the extension
piece in the clamping coupling of an arch-formed brackot piece. Fixed crosswiso
on the end of the extension piece B is a small carrier K having one end projecting,
which end has a screw-threaded hole made through it to receive the adjusting
screw K1, the end whereof rests on the end of the clamping coupling. By turning
the screw either to the right or to the left the extension piece is caused or is free
to slide either upwards or downwards in the coupling, and by this means its
ndjustment is effected.
Fig. 18 exhibits another mode for adjusting the end of the extension piece in a
clamping coupling. In this case it is accomplished by means of a long screw-
threaded bolt, marked L, the T-formed end whereof is shown fixed to the solc
plate of an arch-formed bracket base picce; the fixed bolt projecting thence at a
right angle passes concentrically through the cramping coupling A. A clearing
hole to receive the bolt is drilled or made lengthwise completely through the
straight end of the extension piece; the extreme end of the bolt issuing at that
part of the extension where it is suddenly bent is provided with a nut, and thero
is another nut placed on the bolt near its fixed end. The screwed bolt boing
immovable it will be seen that the adjustment is effected by the nuts.
Figs. 19 and 20 show respectively a side view and a section of a hanging bracket
similar to that already described with reference to Fig. 12 on Sheet 1, excepting
that a split boss B is seen to take the place of the cramping coupling, and a duplex
adjusting screw is adapted to the split boss for the purpose of effecting the vertical
adjustment of the extension piece.
Fig. 21 represents our fourth modification adapted as a hanging bracket to a
beam. The base picce A of this bracket comprises a round truncated tubular piece
cast projecting from the sole plate and having a triangular support on each side.
The body of the extension piece B has the form of a quadrant, and at both ends it
is furnished with a split boss B respectively disposed on the same plane, and
relatively standing one at a right angle to the other. These split bosses are as
usual fitted with cramping bolts, and when making up or combining the parts of.
the bracket one of the split bosses is slid on the tubular part of the bracket base,
and in the other is inserted the shank of the bearing C. In this modification no
adjusting screws are shown, but, when required, those of the duplex kind aro
preferable.
Fig. 22 exhibits a dwarf bracket base piece applied as a hanger to the undersido
of a beam and consisting of a split boss furnished with lugs and a cramping bolt,
and cast upon a sole plate. The straight end of an extension piece is shown on the
split boss. Such a bracket base piece as this at times is found to be very useful
in places where, for want of space, one of the larger kind cannot be used.
Figs. 23 and 24 exhibit respectively a side view and an end view of the fifth
modification of our bracket bearing fixed as a hanger to an overhead beam. The
base piece A of this bracket will bo scen to consist of a truncated tubo centrally
projecting from its sole plate at a right angle, and having an adjustable split boss

page_text: fixed by a cramping bolt on its outer end, which is reduced to the required size.
The plate of the extension piece B is affixed to the back of the boss by two screws
which pass through slotted holes made in the plate, and are screwed into threaded
holes made for their reception in the back of the split boss. Also cast upon the
outer end of the extension piece is a split boss with lugs, and furnished with a
cramping bolt for fixing in this boss the shank of the bearing C. The vertical
adjustment of the extension piece is effected by the screw M, and the cramping
bolts when screwed up make the parts relatively immovable.
Figs. 25 and 26 exhibit respectively a side view and an end view of an adjustable
swivelling bracket and bearing, the sole plate A' of the bracket base A being
affixed to a wall. The base of this bracket has the form of a circular hub, and the
two adjusting screws N¹ and N as adapted to the extension piece B, have, along
with the latter, liberty to rotate on the central screw N³, for the purpose of
adjustment, or for bringing the bearing O (which is one of the ordinary kind) into
suitable position for receiving the shaft. After adjustment the extension piece is
finally fixed to the base piece by tightening up the screw N³. The projecting part
of the extension piece P (which is shown in section by Fig. 27, and in plan by
Fig. 28) carries a plain coupled bearing, the cap part whereof being separated at an
angle of about 45°. The position of the bearing is adjusted laterally by the
screw N, and it is afterwards fixed by the screw No.
Figs. 29 and 30 represent respectively a front view and a section of one of our
combination brackets in a modified form, so far as regards the base piece A, which
is dwarfed for the purpose of adapting the bracket to a wall box, the base picce
consisting of a split boss cast upon a sole plate, similar to that described with
reference to Fig. 22. The straight end of the extension piece B is correspondingly
shortened, and the round shank of a plain coupled bearing is shown fixed in the
split boss B, that is cast on its upper end. In the above Figures no adjusting
screws are shown.
Figs. 31, 32, and 33, exhibit respectively an end view, a side view, and a top
view of a bracket affixed as a hanger to the side of a beam, the bracket base piece A
carrying a split boss B for receiving and finally securing the end of the extension
piece B, which is so arranged that (as shown in the Drawing) the bearing can be
brought into a position suited to receive a vertical shaft, the novelty in this bracket
being chiefly confined to the configuration of the base piece, in combination with a
split boss.
Figs. 34 and 35 represent respectively the plan and side view of a bracket
having its sole plate fastened to a wall. The base piece A' of this bracket is
modified in form, whilst the other parts (viz.), the screws for adjusting the extension
piece B, and the bearing C, are in all respects the same as previously described
with reference to the Figures 1, 2, and 3, on Sheet 1. Instead however of casting two
curved spurs upon the sole plate to form the base piece and the cramping coupling,
as previously shown and described, it will be seen that the foot plate A' has only
one spur cast thereon, but the substance of this spur is so increased that it possesses
strength sufficient to carry all the combined parts of the bracket and bearing,
besides it is capable of being furnished with a split boss B², having the necessary
lugs and a crainping bolt for receiving and rigidly securing the end of the extension
piece after its final adjustuient.
Figs. 36 and 37 exhibit respectively the side view of a bracket secured to a wall,
and a plan of its base piece. This bracket is in all respects the same as that
described and shown by Fig. 22, which exhibits a hanger affixed to a beain,
excepting that the bearing is coupled. It is therefore unnecessary to repeat the
description here.
Figs. 38 and 39 represent respectively an elevation and a plan of a bracket
having the sole plate A' of its base piece aflixed as a pedestal to a floor. Its novelty
consists in the peculiar construction of its base piece A, which is a modification of
the arch-formed class, having a cramping coupling as described in our primary
arrangement (shown by Figs. 1, 2, and 3, Sheet 1). The two segments or side spurs

page_text: of the arch, it will be seen in the Fig. 38, vary in substance, that marked A' being
inflexible, and so much stronger than the other that it is capable of supporting the
whole weight and strain of the bracket. The other spur A is intentionally made
weaker, and consequently lighter, in order that it may more readily yield when the
bolts of the cramping coupling A2 are tightened up to secure the end B¹ of the
extension piece B, our object in this arrangement being the avoidance of all reaction
against the cramping bolts when finally tightened up, and which we effect in our
arch shaped bracket base pieces by modifying their construction as above
described.
Figs. 40 and 41 exhibit respectively an end view and a side view of one of our
brackets having a base picco A suited for attachment to the side of a beam, being
the same base piece as we show in Fig. 32. The novelty consists in the means
whereby we adjust the end B¹ of the extension piece in the split boss B2 of the
bracket base. This is effected by two screws marked K¹ and K², the former being
screwed through a threaded hole made in the end of a carrier piece K, which is
fixed to the extreme end B¹ of the extension piece, at the midlength whereof is cast
a small projecting lug marked K³, through a threaded hole in which the screw K° is
placed. In whichever direction the extension piece may require to be turned to
suit the position or line of the shaft, the ends of the adjusting screws can operate
against the opposite ends of the split boss, and by slackening one screw and
tightening up the other, the round end B¹ of the extension piece is caused to slide
in the split boss in the direction required. The shank of the plain bearing of this
bracket is shown to be adjusted by a tail screw, as in our primary arrangeinent,
but any of the other means of adjustment herein shown may be applied.
Figs. 42 and 43 exhibit respectively an end view and a side view of an elongated
bracket base piece A furnished with a split boss 132, and adapted as a hanger to a
beam. Occasionally we find the use of such a bracket base piece as this very
desirable, as it may be combined with most of the extension pieces and shanked
bearings heretofore described. For adjustment the duplex screws or the two
screws K and K³ mentioned in the last paragraph would be found very
suitable.
Fig. 44 exhibits a bracket bearing similar to the last, but fixed to the surface
of a wall. The bearing is coupled but not lined, and is placed in a position to
receive a horizontal shaft.
Fig. 45 represents a bracket bearing similar to that shown and described with
reference to Fig. 32, excepting that the sole plate of its base piece A is fixed to the
top of a beam instead of to the side, and its extension piece and bearing are fixed
in a position to receive a horizontal shaft instead of a vertical shaft, as shown by
the Figure referred to.
Sheet 3. Our object in supplementing our Specification by the addition of this
Sheet of Drawings is to show the general adaptability of our combination bracket
bearings, and their capability of adjustment according to the various positions in
which they are, can, or may be fixed for the purpose of carrying either horizontal,
diagonal, or vertical shafting or shafts. For example:
Figs. 1, 2, and 3 represent three brackets constructed according to our primary
arrangement, as shown and described with reference to Figs. 1, 2, and 3 on Sheet 1.
These three brackets are all alike, and it will be seen are fixed in three different
positions for the purpose of carrying horizontal shafts (viz.), Fig. 1 is employed as .
a hanger bolted to an overhead beam; Fig. 2 is disposed in the position of a wall
bracket fixed to a pillar; and Fig. 3 is mounted as a pedestal bearing, and is bolted
to a floor.
Figs. 4, 5, 6, and 7 exhibit a range of our bracket bearings constructed according
to some of the modifications described and shown on Sheet 2, and carrying a line
of horizontal shafting under conditions where the means of fixing the sole plates of
the brackets vary considerably. Thus, Fig. 4 is a similar bracket to that shown by
Fig. 45 on Sheet 2, excepting that instead of the sole plate of the bracket base
being shaped for attachment to the top surface of a beam, it is altered in form and

page_text: made concave for the purpose (as shown) of fixing it to the vertical surface of an
upright pillar; Fig. 5 is disposed as a hanging bracket, and in construction is like
the modification shown by Fig. 43 on Sheet 2; Fig. 6 is disposed in a wall box,
and is similar to Fig. 29 on Sheet 2; Fig. 7 is seen as a hanging bracket, being the
same as the inodification described with reference to Fig. 36 on Sheet 2, and which
is there shown as a wall bracket.
Figs. 8, 9, and 10 represent three bracket bearings disposed for carrying a diagonal
shaft, Fig. 8 being a bracket similar to Fig. 12 on Sheet 1, excepting that the sole
plate is made concavo for attachment to a pillar; Fig. 9 shows a bracket of the
same construction attached to a wall, for which purpose its sole plate is, as usual
in such cases, made flat; and Fig. 10 shows a bracket disposed as a pedestal fixed
to a floor. This last bracket is the same as the modification shown by Fig. 43,
which is seen on Sheet 2 disposed as a hanger attached to an overhead beam.
Fig. 11 represents a bracket with its base picco attached to the side instead
of to the top of a beam, as is shown and described with referenco to a similar
bracket exhibited by Fig. 45 on Sheet 2, both of these brackets being arranged for
carrying horizontal shafts.
Fig. 12 represents a bracket fixed to a wall, and having its extension piece and
bearing arranged for carrying the upper end of a vertical shaft; and
Fig. 13 exhibits a bracket fixed as a pedestal upon a floor, and having its bearing
partly bored out and turned upwards to act as a foot stop to receive and support in
position the lower end of the vertical shaft mentioned in the last paragraph. This
same bracket is shown fixed as a wall bracket by Fig. 26, Sheet 2, and is thero
arranged for carrying a horizontal shaft.
Having now fully described the nature, the object, and the advantages derivablo
from the use of our Invention, as shown and described with reference to the Figures
on Sheet 1, and also to the several modifications shown and described with reference
to the Figures on Sheet 2, we wish it to be understood that we lay no claim to the
exclusive construction of brackets with adjustable plummer blocks or bearings
because we have for many years been accustomed to make and use such brackets
and bearings, and adjust them by means of wedges and slotted holes; and we have
occasionally seen and used extension or distancing pieces with such brackets when
from necessity they have been so placed that their bearings fell short of a line of
shaft or otherwise did not reach the position required. We also know that
other combination bracket bearings have at times been introduced, but none
of such bracket bearings that we have ever seen have the unlimited power and
freedom of adjustment, the adaptability to all conditions, positions, and purposes,
and (what is of the utmost importance) the means after adjustment of immovably
and rigidly fixing the several parts so completely in their adjusted positions relatively
that such position is permanently inaintained; therefore what we claim as our
Invention consists as follows, vis.,—
First. We claim the construction of bracket base pieces of the several forms
herein described and shown in the Drawings hereto annexed, such base pieces
having severally a sole plate and either a cramping coupling, a split boss, or a half
bearing, respectively furnished with lugs for cramping bolts, either straight or
staple formed, for the purpose of gripping and rigidly holding the adjustable ends
of extension pieces after their final adjustment, in the manner and for the purposes
herein described; and we include in this claim the base piece described with
reference to Fig. 26 on Sheet 2.
Second. We claim the construction of bracket extension pieces having each either
of the several forms herein described and shown in the annexed Drawings, such
extension pieces severally having one end suitably fashioned for entering or
consorting with either the cramping coupling, the split boss or the half-bearing (as
the case may be) of the bracket base piece, and carrying at the other or outer end
either a split boss with lugs and cramping bolt or a half-bearing with lugs and a
staple formed cramping bolt or bolts, for the purpose of receiving and after adjust-
ment gripping and rigidly holding permanently the shank of the bracket bearing,

page_text: all after the manner and for the purposes herein described; and we also include
in this claim such extension pieces as are described with reference to Figs. 14
and 21 on Sheet 2, as having either a split boss or a half-bearing formed at both
ends.
Third. We claim the construction of shaft and other bearings when such bearings
are severally furnished with a long projecting shank, as herein described and shown
in most of the Figures on the Drawings hereto annexed, the shank of such bearings
being specially designed to enter the split boss, or (as the case may be) engage with
the half-bearing formed on the outer end of the extension piece of the bracket with
which it is combined, and after adjustment by screws or otherwise to be gripped
and rigidly held thereby by means of cramping bolts, in the manner and for the
purposes described.
Fourth. We claim the use of cramping couplings and split bosses respectively,
furnished with lugs and one or more cramping bolts; also the use of half-bearings
and staple-formed bolts as a means of connecting, and after adjustment permanently
fixing together the principal parts of our combination bracket bearing (viz.), the
base piece, the extension piece, and the shanked bearing, after the manner described
with reference to the several Figures shown on the Drawings hereto annexed, and
for the purposes herein set forth.
Fifth. We claim the modes of adjusting the extension pieces of our brackets after
being adapted and connected to their several base pieces, and the shanks of our
bearings after being adapted and connected to the outer end of extension pieces
by means of adjusting screws, either single or duplex, and severally constructed
and applied after the manner and for the purposes herein described with reference
to the Figures on the Drawings hereto annexed.
Sixth. We claim the construction and use of such self-lubricating bearings as are
cast with a long shank, for the purposes herein described and as shown by the
Figures 19 and 20 on Sheet 1 of the Drawings hereto annexed; and
Seventh. We claim the mode described and shown by the Figures 12, 13, and 14,
on Sheet 1 of adapting a strap guide to the end of a bearing, vis, by means of an
annular clip, when such bearing is cast with a long shank, for the purposes herein
set forth.
In witness whereof, we, the said Joseph Samuel Taylor and Stephen William
Challen, have hereunto set our hands and seals, this Twenty second day of
July, in the year of our Lord One thousand eight hundred and eighty.
