Improvements in and connected with Hand and Machine Tools for
Tightening up Spokes, Drilling, Tapping, and the like.
We, JOHN HENRY PLAYER, of 5, Wren Street, Coventry, in the County of
Warwick, Tool Maker, and WILLIAM DREDGE PLAYER, of 112, Newhall Street,
Birmingham, aforesaid, Manufacturer, do hereby declare the nature of my said
invention to be as follows;
1
Our invention has for its object improvements in and connected with hand
and machine tools by which we are enabled when using our tool for tightening
up spokes to indicate when sufficient tension has been put upon each spoke in
building up a wheel, or when sufficient tension has been put upon a drill, tap or
the like.
In carrying our invention into practice we form a frame or case in one end
of which we mount a spindle provided with suitable bearings and on the inner
end of this spindle which is formed conical we mount a spur wheel and in the
flange formed at the back of this spur wheel we fix one end of a suitable spring
the other end of which bears against an eccentric formed on or attached to the
spindle. We then fix a cap or cover onto the flange of this spur wheel which
bears upon another conical bearing fixed on the spindle and this cap or cover
holds the spindle in position. We now mount another spur wheel on a hollow
tube or sleeve which gears with the spur wheel on the end of the spindle, and
this hollow tube or sleeve is mounted in suitable bearings in the frame or caso
at right or about angles to the spindle. A slot is formed in this hollow
tube or sleeve running its whole length and also in the spur wheel and in the
ends of the frame or case. One end of this hollow tube or sleeve is solid and
i. the centre of this end we form a square, or other suitably shaped hole having
a slot which communicates with the other slot. To tighten up a spoke it is passed
through the slot into the hollow tube or sleeve and then the tool is moved until
the head of the spoke nipple enters the hole in the solid end of this tube or
sleeve, the spindle is now revolved by attaching a flexible driving shaft to the
end which extends beyond the exterior of the frame of case or the spindle may
be revolved by hand power by attaching a handle or the like to this end of the
spindle, when the spindle revolves it causes the two spur wheels to revolve also
and consequently the hollow sleeve or tube and the nipple by which means
the spoke is tightened up but as soon as a sufficient tension has been put upon the
spoke the strain on the spindle overcomes the tension of the spring and the
spindle revolves in its bearings without operating the gear wheels. Instead of
placing the spring which indicates when sufficient tension has been put upon
the spoke in the interior of the case or frame it may be placed in any position
between the driving medium and the part which grips the nipple of the spoke
the parts being suitably arranged for this purpose. It will be quite evident our
tool may be used for other purposes such for instance as indicating when a certain
tension has been put upon drills, taps or the like by a slight alteration. Fixed

page_text: in the interior or on the exterior of the frame or case is a spring catch which
comes in contact with a peg or projection attached to the hollow sleeve when it
is revolved in the opposite direction so as to indicate when the slot in this sleeve
is opposite the slots in the frame or case to enable the tool to be withdrawn from
the spoke. Instead of using conical bearings ball bearings may be used in all 5
parts.

Improvements in and connected with Hand and Machine Tools for
Tightening up Spokes, Drilling, Tapping, and the like.
We, JonN HENRY PLAYER, of 5, Wren Street, Coventry, in the County of
Warwick, Tool Maker, and WILLIAM DREDGE PLAYER, of 112, Newhall Street,
Birmingham, aforesaid, Manufacturer, do hereby declare the nature of our said
invention and in what manner the same is to be performed. to be particularly
described and ascertained in and by the following statement:—
Our invention has for its object improvements in and connected with hand
and machine tools by which we are enabled when using our tool for tightening
up spokes to indicate when sufficient tension has been put upon each spoke in
building up a wheel, or when sufficient tension has been put upon a drill. tap or
the like.
In carrying our invention into practice we form a frame or case in one end
of which we mount a spindle provided with suitable bearings and on the inner
end of this spindle which is formed conical we mount a spur wheel and in the
flange formed at the back of this spur wheel we fix one end of a suitable spring
the other end of which bears against an eccentric formed on or attached to the
spindle. We then fix a cap or cover onto the flange of this spur wheel which
bears upon another conical bearing fixed on the spindle and this cap or cover
holds the spindle in position. We now mount another spur wheel on a hollow
tube or sleeve which gears with the spur wheel on the end of the spindle, and
this hollow tube or sleeve is mounted in suitable bearings in the frame or case
at right or about angles to the spindle. A slot is formed in this hollow
tube or sleeve running its whole length and also in the spur wheel and in the
ends of the frame or case. One end of this hollow tube or sleeve is solid and
in the centre of this end we form a square, or other suitably shaped hole having
a slot which communicates with the other slot. To tighten up a spoke it is passed
through the slot into the hollow tube or sleeve and then the tool is moved until
the head of the spoke nipple enters the hole in the solid end of this tube or
sleeve, the spindle is now revolved by attaching a flexible driving shaft to the
end which extends beyond the exterior of the frame or case or the spindle may
be revolved by hand power by attaching a handle or the like to this end of the
spindle, when the spindle revolves it causes the two spur wheels to revolve also
and consequently the hollow sleeve or tube and the nipple by which means
the spoke is tightened up but as soon as a sufficient tension has been put upon the
spoke the strain on the spindle overcomes the tension of the spring and the
spindle revolves in its bearings without operating the gear wheels Instead of

page_text: position between the driving medium and the part which grips the nipple by
suitably arranging the various working parts and also that the holding medium E
may be driven by other means instead of bevel wheels. Fixed in the interior of
the frame or case is the spring catch H which is set at an angle and which serves
as a stop piece for the peg or projection h¹ which is secured to the tube or sleeve
in such a position that when this tube or sleeve is revolved in one direction the
stop ¹ comes in contact with the spring catch H when the slot F is exactly
opposite the slots f, f and fa thus indicating when all the slots are opposite or
in a line to enable the tool to be withdrawn but when the tool is revolved in the
reverse direction this stop h¹ slides over the spring catch H.
It will be evident that we may use ball bearings in place of cone bearings and
that our tool may with equal advantage be used for other purposes such for
instance as measuring and limiting when a certain tension has been put upon
drills, taps, bits or the like by slightly modifying its construction.
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;-
CLAIMS.
First: The spoke tightening device herein set forth and shewn consisting of
a nipple holder or spanner driven by a train of wheels or their equivalents from
any convenient driving spindle B whether driven by hand or power but having
a spring S or its equivalent interposed between the power applied and the nipple
holder for the purpose of measuring and limiting the strain put upon each spoke
as the nipple is screwed up.
Second A hand or machine tool for tightening spokes comprising the case
or frame A the spindle B with its bevel wheel W and the limiting or measuring
spring S the tube or sleeve E with its corresponding wheel W all operated in
the manner and for the purpose substantially as herein set forth and as shewn
upon the drawings.
Third: A tool or spanner adapted for drilling tapping screwing and the like
composed of the drill holder or spanner or head E revolved by suitable gear, the
pressure applied being measured by the spring and the whole mounted in a
suitable frame or casing so as to constitute a handy tool and driven by hand or
power.

page_text: placing the spring which indicates when sufficient tension has been put upon
the spoke in the interior of the case or frame it may be placed in any position
between the driving medium and the part which grips the nipple of the spoke
the parts being suitably arranged for this purpose. It will be quite evident our
tool may be used for other purposes such for instance as indicating when a certain
tension has been put upon drills, taps or the like by a slight alteration. Fixed
in the interior or on the exterior of the frame or case is a spring catch which
comes in contact with a peg or projection attached to the hollow sleeve when it
is revolved in the opposite direction so as to indicate when the slot in this sleeve
is opposite the slots in the frame or case to enable the tool to be withdrawn from
the spoke. Instead of using conical bearings ball bearings may be used in all
parts.
In order that our invention may be clearly understood and easily carried into
practical effect we have appended hereunto a sheet of drawings upon which we
have shewn examples of our tool.
Figure 1 is a plan view of our tool complete.
Figure 2 is a side elevation shewing the sides of the case removed.
Figure 3 is a part sectional view of Figure 2.
.
Figure 4 is an end view of Figure 2 with the sides of the case fixed in position.
Figure 5 is an internal view of the tension portion of our tool.
In carrying our invention into practice we form the frame or case A in one
end of which we mount the spindle B in the cone bearing and on the inner
end of this spindle which is formed conical we mount the bevel wheel W
provided with the adjustable conical bearing wl in which the coned end of the
spindle fits. This wheel is also formed with the flange in which we fix the
end of the spring S the other end bears against the eccentric_or cam_b
formed on or attached to the spindle. We then fix the cap or cover D over the
flange and this cap or cover is formed with a conical hole which takes its
bearing on the cone fixed on the spindle immediately above the eccentric b³ by
which means the spindle and wheel are secured together. We now mount the
bevel wheel W on the tube or sleeve E which gears with the bevel wheel W and
this tube or sleeve which is formed with the conical bearing e¹ at one end is
mounted in the frame or case at or about right angles to the spindle B and is
held in position by the collar which is fixed at the other end by screws or
otherwise. The slot F is cut or formed along the length of this tube and also
in the spur wheel Ws and corresponding slots f, f and f³ are cut or formed in
the edges of the sides of the frame or case and in the collar e. The coned end
of the tube or sleeve E is formed solid and in the centre of this end we form the
square hole e¹ with the slot which communicates with the slot F. The distance
pieces or collars J and J are provided so as to keep the various parts in position
and the lock nuts and which screw onto the spindle hold the parts together.
The modus operandi is as follows:-
To tighten up a spoke the tool is passed onto the spokes by means of the slot F
so that the tube or sleeve E surrounds a portion of the spoke, the tool is then
moved until the nipple enters the hole e³, the spindle is now revolved by attach-
iug a flexible shaft to the end 6' or the spindle may be revolved by a hand wheel
fixed to this end of the spindle or by other means thus causing the two spur
wheels to revolve also and consequently the sleeve or tube E and the spoke
nipple, by which means the spoke tightened up and as soon as sufficient tension
has been put upon the spoke the strain on the spindle overcomes the tension of
the spring S which measures and limits the strain put upon such spoke which
bears against the cam 3 thus allowing the coned end 62 of the spindle to revolve
in its bearing to and the bevel wheels W and W to remain stationary thereby
indicating to the operator that sufficient tension has been put upon the spoke.
It will be evident that the spring which measures and limits the amount of tension
to be put upon the spoke may be of various shapes and may be placed in any
