Year: 1867

page_text: LETTERS PATENT to James Reid, of the Firm of Neilson and Company,
of Glasgow, in the County of Lanark, North Britain, Engineer, for the
Invention of "IMPROVEMENTS IN APPARATUS FOR FINISHING PARTS OF
LOCOMOTIVE WHEELS."
Sealed the 10th March 1868, and dated the 13th September 1867.
PROVISIONAL SPECIFICATION left by the said James Reid at the Office
of the Commissioners of Patents, with his Petition, on the 13th September
1867.
I, JAMES REID, of the Firm of Neilson and Company, of Glasgow, in the
County of Lanark, North Britain, Engineer, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN APPARATUS FOR FINISHING PARTS OF
LOCOMOTIVE WHEELS," to be as follows, that is to say :-
This Invention relates principally to the crank pin holes in locomotive
wheels, and the improved apparatus comprises arrangements for accurately
adjusting a pair of wheels by means of the journals of their axle for insuring
the crank pin holes being accurately at right angles to each other and parallel
to the journal axis, and for forming these holes with a uniform and correct
taper. The improved details for forming the taper are also applicable to the
axle holes.
The apparatus is by preference mounted on truck wheels so that it can be
run under any convenient crane to receive a pair of wheels to be operated
upon, and to be thence transferred to any locality where a pair of driving belts

page_text: can be conveniently be applied to it. The pair of wheels having been previously
fixed on their axle, this is placed horizontally in the machine with the journals
in bearings provided for them and adjustable at different distances apart.
These bearings are also provided with accurately formed lining pieces adapted
for different diameters of journals. Between the bearings the framing or
body of the apparatus is formed with equally inclined surfaces made accurately
at right angles to each other, and on these surfaces are fixed two bracket
castings or heads carrying drill or tool spindles with their driving and feeding
gear. These heads can be fixed at either diagonal pair of corners of the body
to suit axles with either the right-hand pin or the left-hand one leading; and
provision is made for different throws of crank by having gauge holes
corresponding to the various throws ordinarily adopted accurately bored in the
inclined body surfaces to receive pins or bolts in the brackets or heads. Each
tool spindle is made tubular and is not fed longitudinally, but the cutter is
fed along a groove or slot formed through the side of the tubular spindle
which is at that part shaped with the required taper so that the cutter follows
this taper and shapes the crank pin hole accordingly.
The driving gear
preferred consists of short horizontal shafts with fast and loose pulleys to be
driven by belts and actuating the tool spindles by worm wheel or bevil
gearing.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Reid in the Great Seal Patent Office on the 12th
March 1868.

page_text: an instru-
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS FOR
FINISHED PARTS OF LOCOMOTIVE WHEELS," upon the condition (amongst others)
Lat I, the said James Reid, my executors or administrators, by
ment in writing under my, or their, or one of their hands and seals, should par-
ticularly describe and-ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said James Reid, do hereby declare the
ature of my said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
in writing, reference being had to the accompanying Drawings, that is to
say-
My said Invention relates principally to the crank pin holes in locomotive
wheels, and my improved apparatus comprises arrangements for accurately
adjusting a pair of wheels by means of the journals of their axle for insuring
the crank pin holes being accurately in planes at right angles to each other
and parallel to the journal axis, and for forming these holes with a uniform
and correct taper. The improved details for forming the taper are also
applicable to the axle holes.
And in order that my said Invention and the manner of performing the
same may be properly understood I have hereunto appended a Sheet of
explanatory Drawings to be herein-after referred to and representing a
modification of my improved wheel finishing apparatus.
Figure 1 is a plan; Figure 2 is a transverse vertical section, and Figure 3
is a sectional side elevation; Figures 4, 5, 6, and 7, are enlarged views of
one of the tool spindles and its accompanying details. The same reference
numerals are used to mark the same or like parts in all the Figures.
The apparatus is represented as mounted on a truck frame 1, with wheels 2,
but it can if wished be fixed to a stationary foundation. I however prefer to
arrange it as shown, so that it can be run under any convenient crane to
receive a pair of wheels to be operated upon, and to be thence transferred to
any locality where a pair of driving belts can be conveniently applied to it.
The pair of wheels 3, 4, having been previously placed and keyed on their
axle 5, this placed horizontally in the machine with the journals 6 in
bearings 7, 8, provided for them and furnished with accurately formed
lining' pieces 9 (Figure 2) adapted for different diameters of journal. The
bearings 7, 8, are also adjustable at different distances apart; to obtain which
adjustment the body of the machine is made in two separate castings 10, 11,

page_text: and one 10 has a rack 12 fixed to its under side, having in gear with it a
pinion 13 on a shaft 14 carried in the truck frame 1, and formed with
squared ends to receive keys or handles. Elongated holes are provided in the
truck frame 1 for the bolts, by which the adjustable body part 10 is fixed to it,
and these bolts are loosened when a change is required in the adjustment.
The provision for adjusting the bearings 7, 8, more or less apart is convenient
for a private establishment for constructing locomotives where various gauges
have to be provided for; but when only one gauge has to be provided for,
as at the works of a railway company, the body of the machine may be
made in a single casting. For such works also it may be convenient to
have the machine permanently fixed to a stationary foundation. Between
the bearings 7, 8, the body or framing 10, 11, is formed with equally
inclined surfaces or seats 15, 16, on opposite sides of the longitudinal centre
line, and the surfaces 15, 16, on one side are made accurately at right
angles to the corresponding surfaces :15, 16, on the other side. On these
inclined seats a series of bracket castings or heads are fixed for carrying the
boring bars or tool spindles with their driving and feeding gear. There are
two boring bars which are set at diagonally opposite corners, but for the sake
of clearness I will describe the details connected with one only, those of the
other being exactly alike. The boring bar 17 is carried in two bearing heads
formed on one casting 18, and has on it between these heads a worm wheel 19
which turns it by means of a key and groove, and which is driven by a
worm 20 on a shaft 21 carried in bearings in the same casting 18. The
shaft 21 is provided with fast and loose pulleys 22 to receive a driving
belt from any convenient shaft. The back end of the boring bar 17, which
end is of reduced diameter, has on it a tube 23 screwed externally to work
in an internally screwed bush 24, which is held in a bearing head 25,
and which has a spur feed wheel 26 keyed on its projecting back end. The
screwed tube 23 is prevented from turning by means of a groove and key, and
it is held on the boring bar 17 so as to make this bar move longitudinally with
it by nuts 27 screwed on the outer end of the bar. The feeding is effected
by means of an eccentric formed on the side of the worm wheel 19, the strap
of which eccentric actuates a rocking spindle 28. A lever and link at the
other end of the rocking spindle 28 imparts a reciprocating motion to an
armed ring 29 loose on a flange on the feed spur wheel 26, on which the
armed ring acts by means of a reversible catch 30. The front end of the
boring bar 17 is formed with a transverse slot, and in this a small block 31
which is the tool holder has the small transverse movement necessary for pro-
ducing the taper of the crank pin hole 32. The steel tool or cutter 33 fits

page_text: in a square socket in the holder 31, and is fixed by a pinching screw. The
holder 31 is formed with flanges at one end, and a flange piece is fixed upon
the other end after the holder is put into its slot. These flanges bear on the.
outside of a tube 34 fitted on the boring bar 17, so that this bar can move
longitudinally in it.. The tube is formed with longitudinal slots in which the
ends of the holder move as the bar is fed along; and the outside of the tube
is turned concentric with an axis slightly inclined to the axis of its bore in a
plane passing through the centre lines of the slots, which causes the edges
at the slots that the holder flanges bear on to be slightly tapered or inclined.
With this arrangement as the tube 34 is stationary from bearing against the
casting 18 the longitudinal movement inwards of the boring bar 17 causes
the slight transverse movement of the tool that produces the required taper.
The tube 34 is kept against the casting by a lever collar clutch 35, which
prevents it from moving outwards with the boring bar. The castings 18 and 25
which carry the boring bar and its accessories can be shifted in such a way that
the two tools can be placed at either diagonal pair of corners of the body or
frame to suit either a pair of wheels with the right-hand crank pin leading, or
a pair with the left-hand one leading. When effecting a change from one
diagonal disposition to the other the various parts are separated, the boring
bar 17 and the screwed tube 23 are entered into their places the opposite
way; and the castings 18 and 25 are respectively fixed on the seats 15 and 16,
represented in the Drawing as unoccupied. If the parts are shifted to the
opposite ends of the same sides the larger casting 18 has not to be turned
about, but the smaller one 25 has to be so turned. Duplicate lugs for carrying
the rocking spindle 28 are required and provided, and the worm wheel 19
is formed with eccentrics on both sides of it, so that it can be put into its
place either way. Provision is made for different throws or effective lengths of
crank by having gange holes 36 corresponding to the various throws ordinarily
adopted accurately bored in the inclined body surfaces or seats 15, 16, to
receive pins fixed in the under sides of the brackets or castings 18, 25, or
screw bolts, by means of which these castings are fixed to the seats, the holes
and pins or bolts being carefully bored and turned to fit each other accurately.
The surfaces of the seats 15, 16, are parallel to planes at right angles to each
other, and passing through the centre line or axis of the journal bearings 7, 8,
and the boring bar bearings in the castings 18, 25, are accurately constructed
so that their centre lines are in the said planes in all positions of those
castings.
Having thus particularly described my said Invention, and the manner in
which the same is to be performed, I have to state that I do not restrict

page_text: myself to the precise details herein described or delineated; but that what I
believe to be novel and original and claim as the Invention secured to me
by the herein-before in part recited Letters Patent is,-
The arrangingand combiningtogether of the parts of apparatus for finishing
parts of locomotive wheels, substantiallyin the improved manner herein-before
described.
And the setting or adjusting of the various parts of the apparatus in relation
to bearings provided for the axle journals of thewheels operated upon substan-
tially as herein-before described.
In witness whereof, I, the said James Reid, have hereunto set my hand
and seal, this Eleventh day of March, in the year of our Lord One
Witness,
IND HUNT,
Patent Agent,
Glasgow.
