JOSEPH NOTTINGHAM SMITH, of Jersey City, in the State of New Jersey, one of
the United States of America, Gentleman. "DRESSING CAR AXLES AND THE
CAPS FOR THE SAME, AND FOR LUBRICATING THE JOURNALS OF RAILWAY CAR-
RIAGE AXLES."
My Invention relates,―
First. To improvements in a machine for dressing the journals of railway carriage
axles, whereby the said dressing may be accomplished without the necessity of
taking the axle, with the wheels fixed thereon to a lathe.
Second. To improvements in a machine, whereby the bearing boxes or caps for
the journals may be truly dressed to a curvature of any desired radius within the
limits of the machine by means of a rotating table, capable of a variable and
eccentric movement with respect to a rotating cutter operating in connection
therewith.
Third. To improvements in oiling or lubricating apparatus for the journals of
railway carriage axles, whereby a better distribution and a saving in the oil is
effected.
Fourth. To improvements in dust excluding devices, applied to axle boxes for
railway carriages.
Fifth. To improvements in the ball-and-socket joint connection between the saddle
and axle box.

page_text: Sixth. To improvements in the door of an axle box, whereby it is caused to assist
in supporting the stopping bar, and to means for securing it when closed.
The exact nature of the improvements of which my Invention consists will
be readily understood from the following description and Drawings, in which the
first eight Figures illustrate my improved machine for dressing the axles or journals
of railway carriages, in which,―
Figures 1 and 2, taken together, illustrate my complete machine for this purpose
in proper position for dressing the journals of a car axlo; Figure 1 shows one
dressing head in mid-section, and Figure 2 shews the other in side elevation.
Figure 3 is an interior clevation, shewing the rotative and fixed mechanism.
Figure 4 is an elevation of the outer plate, bearing the stop mechanism.
Figure 5 is an elevation of the inner face plate and the cutter.
Figure 6 is a detached sectional view.
Figure 7 is n view, shewing the countersink for making a socket for the center.
Figure 8 is an end elevation.
It has been customary heretofore when the journals of a railway carriage axle
have become untrue from irregular wear, to remove the same from the truck to some
point, where it could be put in a lathe and the journals turned true again. This
involves considerable trouble and expense. With my machine, which is portable, it
is only necessary to remove the axle from the truck, when the dressing may be dono
without removing the wheels from the track.
Generally speaking, this machine embraces two dressing heads, constructed aliko
and connected by rods or ties long enough to bring the heads into proper relative
positions with respect to the journals. Both dressing heads operate alike, and inde-
pendently, and may be operated simultaneously by different operations. Ono only
therefore will be minutely described.
A, A, are end plates, bolted and tied firmly together by means of rods B, B.
Arranged adjustably upon the plate A is a collar a, bearing a foot pad C to rest
upon the tread of the wheel D. E is a carriage arranged to play in vertical guides
on the face of the end plate, and provided with an adjusting screw b. This carriage
bears another carriage F, which moves crosswise, and which is also operated by
means of a screw c. This latter bears two rollers d, d, arranged to revolve on hori-
zontal axes, as shown. The purpose of these will be explained farther on.
G is a
kind of fixed internal gear, formed of a flanged rim provided with internal teeth,
best seen in Figures 3 and 5. This rim has lugs e, e, which engage guiding grooves
or ways in the end plate A, and prevent the rim from rotating, while they permit
it to move along the ways. H is an inner, and I is an outer plate, between which
aro mounted the gears. J is a tubular flanged boss or hub, arranged to turn in a
cross bearing K, attached to or forming a part of the end plate A, and to receive a
cylindrical center L.
The slenderer portion or shank of this center, as well as that of the countersink,
illustrated in Figure 7, is fitted with a tubular sleeve held on by a nut, and this
sleeve is screw threaded to fit internal threads cut in the bore of the boss J, so
that by it the center or countersink may be fed in or out as desired.
In the flango of the boss J are rigidly secured feed screws f, f, which engage
rotating toothed nuts g, g, which have bearings in the outer plate I. The toothed
nuts g, g, are driven uniformly in one direction by means of sundry idler pinions h, h,
which derive motion from a pinion i attached to or forming part of the driving
pinion j, which latter meshes with the internal teeth on the rim G.
To provide a means for throwing the feed screws out of gear with the rim G, I
attach the pinions i, j, together by means of a square or polygonal rod k, which has
a flanged head, the edge of which engages a spirally-inclined groove in the edge of
a handled disk l, mounted upon the plate I, as shown. When the disk / is rotated,
the rod k is drawn part way out, and the connection between the pinions is broken,
thus stopping the feed by permitting the pinion i to revolve independent of the
driver j around the center. This arrangement is clearly shown in Figure 1.
With especial reference to Figures 3, 4, 5, and 6, m is a shaft or axle bolt, bearing

page_text: on one end, between a collar and nut, a spring plato n notched to receive the end of
a feed spring M secured to the plate I. On the same axle bolt is mounted a scale
plato o, interposed between the plate n and the plate I, and turning loosely on the
bolt. This plate and the plate n are connected together by an adjusting screw p,
and the former is normally pressed against a stop pin or stud q. This device is for
adjusting or regulating the depth of the cut, and will be referred to again.
Secured to the bolt m on the inside of the plate I is a radius bar N, on which is
mounted the cutter O, which may be provided with cutting edges, both on its faces
and its periphery. This cutter bears a pinion, which gears through an idler, with
a pinion on the bolt m. The pinion is compound, and its lesser part meshes
with the teeth on the rim G, whereby it derives motion and communicates it to the
cutter.
Having described the mechanism so far, I will now describe its operation.
The axle bearing the wheels is removed from the truck and car, but left standing
upon the track if desired. The pads C having been properly adjusted, the machine
is set upon the wheels, as shown in the Drawing. The re-inforce P being. less liable.
to demoralization than any other part of the axle outside of the wheel, and its
diameter being known or ascertained, the rollers c, d, aro lowered far enough to rest
upon the said re-inforce and support the head in its proper relative position with
respect to the axle centres. Some horizontal, as well as vertical adjustment, will
usually be necessary to effect this purpose, as the re-inforce rarely extends beyond
the concavity of the wheel.
The first operation is to dress the face of the button 8, which is done by setting
the cutter with respect to the button, so that it will dress a light chip off the face of
the latter. The feed is now thrown off by means of the grooved disk being
caused to act upon and draw out the square coupling rod k. To give the cutter the
necessary depth of cut or travel, the plate o must be properly adjusted with refer-
ence to the stud q by means of the screw p. All being now in readiness the head
is revolved by means of a crank Q or other equivalent device.
The stationary internal gear teeth on the rim G impart rapid rotary motion to tho
cutter O while it is being more slowly carried around the face of the button by the
crank, and fed up to the work by the feed spring M.
After the button has been faced off, the countersink shewn in Figure 7. may be
run in for the purpose of enlarging and truing the original center, or for making a
new one. Its work being accomplished, it may be replaced by the center L. As
soon as the center is in place, the frame bearing the rollers d, d, may be lifted as
they are no longer needed.
The cutter is now fed forward far enough to rest upon the flange of the button, .
and the stop plate o, adjusted to allow the cutter to take off just what is needed
and no more. The cutter having trimmed the edge of the button flange, it is now fed
forward far enough to take a light truing cut down the inner face of the button flange,
being allowed to cut into the journal only deep enough to effect a truing cut, unless
the journal is to be reduced, which may of course be done. Having run the cutter
down to the proper depth, and adjusted the scale plate to prevent any deeper cut,
the feed is put on, and the cutter is allowed to feed and traverse the journal at the
same time that it rotates on its axis and travels around the journal.
After having dressed close up to the shoulder of the re-inforce, the cutter may be
lifted upon the re-inforce and the latter be dressed.
The machine is readily removed by simply running back the centers.
The journal having been properly dressed, it is important that the antifriction
metal of the bearing be truly dressed to fit it. To accomplish this purpose the
second part of my Invention, comprehended in Figures 9, 10, 11, 12, and 13, is
especially adapted wherein.
Figure 9 is a vertical mid-section of this part of my Invention.
Figure 10 is a side elevation of the same.
Figure 11 is a plan view of the rotating table, a portion of which is broken away.
the coins

page_text: Figure 12 is a plan view of the machine, with the rotating table and the upper
parts removed.
Figure 13 is a plan view of the under side of the machine.
This machine is especially adapted to dressing out the caps of axle journals and
boxing for shafts to any given curvaturo, but it may also be used, and is well adapted
for milling plane surfaces and milling out hollows or recesses.
In the precise construction shewn in the Drawings A' is a bed piece, and B' is a
plate mounted over it upon posts. This construction gives free access to the gearing,
otherwise a hollow base might be used as well. C¹ is a cutter or tool, which may be
of any form or contour required for the work in hand.
This cutter is provided with an adjustable step or center al, which fits into a
bracket bolted to the plate B. At the top it finds a bearing in another
adjustable center c', in an arm or arch bolted to some fixed part of the machino.
On the lower part of the cutter is fixed a pinion d', which connects through
sundry intermediate spur wheels and pinions, which intermesh with mitro
gears e, el. These gears are driven by a crank or pulley D', as may be deemed
most desirable.
The intermediato gears are for the purpose of speeding up the cutter, and may be
varied to suit the speed of the driver and cutter, as in other machines.
E' is a bed adapted and arranged to receive a rotating table F'. This bed has a
diametrical dovetail groove across its lower face to engage a corresponding strip f'
on the plate B¹, and it is arranged to traverse on this strip by means of a traverso
screw g, which rotates in a collared bearing attached to the fixed plate. The upper
side or face of this bed has concentrically arranged flanged or ribs h', h', and its
internal periphery is undercut or beveled to receive a correspondingly beveled
ring i, which is screwed to the table F, thus affording a means of attaching the
table to the bed, and at the same time leaving it free to rotate thereon. Theso
screws also serve to clamp fast the table to its bed when rotation is not desirable.
On the margin of the table, or under the projecting edge of the same, are arranged
cogs or teeth, which mesh with an idler pinion j¹, and through it derive motion from
a pinion k¹, on the same shaft with one of the mitre gears e'. Thus rotary motion
is imparted to the table from the same motive power that actuates the cutter.
Gis a lever which turns on the shaft of the pinion as a fulcrum pivot. On
this lever is mounted a lever ', in which the idler pinion j' finds an eccentric bearing.
This eccentricity of the bearing is such that by manipulating the lever 1, the idler
may be thrown in and out of gear with the teeth on the table, and at the same time
remain in mesh with the pinion k¹.
When the table is caused to traverse by means of the before-mentioned traverse
screw, tho relative position of the idler pinion and the teeth upon the table will
change, owing to the rotundity of the table, and to preserve the proper contact I
provide a curved slot in the pivoted lever G' and a pin m' in a rigid arm attached
to and projecting from the bed E¹ to engage said slot, by which means the pinion is
caused to adjust itself properly to the teeth on the bed or table.
To compensate for the necessary wear arising from the movement of the bed E'
on the strip f¹, a portion of the latter is constructed in the form of a beveled or
tapered key n', arranged to be adjusted longitudinally by means of a screw o'.
It will be seen that the cutter is arranged within an opening in the center of the
table F, and that the radial adjustment of the table is limited by the size of this
opening. I contemplate however in some cases driving the cutter from above, and
permitting it to reach down no lower than the table, in which caso the table may
traverse beneath it.
To clamp the work fast while it is being dressed, and to present it properly to
the cutter,
provide a suitable chuck or holder, which I will now describe, with
especial reference to Figures 9, 10, and 11 of the Drawings.
H' is a bed piece attached to the table F1, upon which is arranged to traverso
laterally a carriage 1', the means of operating it being a traverse screw p', similar
to that used in lathes. Upon this is mounted another carriage J, which is arranged.

page_text: to traverse at right angles to the part upon which it is mounted, it being propolled
by a screw q¹.
Upon this is mounted a plator, bearing pivoted jaws 8', s', arranged to bo
brought together by means of right and left screws t', t, having a central boss or
nut arranged to play between lugs on the plate 7. This latter plate bearing tho
jaws is arranged to traverse the bed upon which it rests, being driven by tho
screw u'.
Krepresents a cap for a journal clamped fast in the jaws, and drawn back by
the scrow u' until it rests firmly against the bearing post v on the carriage J.
To enable the operator the more readily to adjust the table F1 to the proper
eccentricity, a graduated scale may be marked upon the strip f¹, whereby tho said
eccentricity can be noted by the travel of the periphery of the bed over the same
and the degree regulated.
The operation is simple. The proper shaped cutter being fixed in its bearings,
and the proper degree of eccentricity, if any, given to the table and bed by means
of the traverse screw, the machine is put in motion.
As the clamp passes around to the farther side of the eccentric circle of travel, a
cap or other article to be dressed or cut is slipped in and clamped fast. As it travels
around it nears and finally comes in contact with the cutter, which dresses it out as
indicated in Figure 11.
As the caps or pieces are dressed they may be removed and replaced by others
without stopping the machine or the rotation of the table.
The lateral adjustment of the clamp enables me to cut or dress out an elongated
or oblong recess adapted to cover two journals rotating in contiguous or adjacent
bearings.
By throwing the table out of rotative gear and setting tight the screws that
serve to clamp it fast to its non-rotative bed, the machine may be adapted to
dressing or milling a plane surface. This may be done by fixing the pieco properly
to the table, and carrying it past the cutter by means of the traverse movement of
the table.
The cutter C¹ being readily taken out when a cylinder or other interior opening
is to be dressed, it is first removed and passed through the aperture before being
finally fixed in its bearings.
The journal of the carriage being properly dressed and trued up, and the bearing
cap being truly milled out and fitted thereupon, they are in condition to be fitted
with my improvements in the axle boxes and saddles, and in oiling and lubricating
apparatus for the journal connected therewith, which latter improvements constitute
the third, fourth, fifth, and sixth parts of my Invention, and are illustrated in
Figures 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, and 26.
The axle box is herein shown as adapted to a skeleton truck, but many of the
novel features are as well adapted to be used in pedestals of special and common
forms.
A is the saddle which is provided with bored recessed or tubular lugs to receive
bolts, which secure it between the straps of the truss.
The lower lugs of the saddle are recessed to receive lugs a", all, cast on or
attached to the housing B", while a spherical segment b¹¹ on the latter rests in a
corresponding concave or hollow in the roof plate of the saddle.
A ball-and-socket support is shown in a Patent formerly granted to me, and I
make no broad claim to it herein, but in that case the ball was cast with and formed
a part of the housing.
This construction is objectionable, inasmuch as the ball should be chilled to adapt
it to the end in view, and this from the unequal strains produced in the casting
hazards the integrity of the housing.
In my present Invention the spherical segment 6" is cast separately of chilled or
hardened iron or steel, and adapted to fit in a recess or socket in the roof of the
housing. It may be attached by means of a wire staple, preferably cast in the

page_text: segment, the ends of which pass through holes in the roof of the housing, and are
clinched on the inside.
The lugs a, a, on the lower edge of the housing do not fit snugly into the
recesses in the saddle, but have considerable play, as indicated in Figure 18, so as to
permit a moderate degree of lateral swing to the car. They serve however to check
too much movement.
the same.
The stopping bar C", which is hollowed out to receive the vibrating oil pump,
shown in a former Patent granted to me, rests between lugs on the housing at both
bottom and top, and the upper back corner engages a notch c" in the door D" of
To add further support to the stopping bar it is provided with a lug nt
the back, which bears against the bevilled front of the housing, just below the door
opening. The bar is prevented from moving in the other direction by lugs on the
sides of the housing, and by the cap E", which is interposed between it and a
shoulder formed in the roof of the housing.
The door D is hinged above at ", and is provided with a catch e" on its inner
face, which engages, when the door is shut, a spring hook f", pivoted preferably to
the stopping bar; a groove at g" in the edge of the opening below the door
permits the insertion of a slender rod, by which the hook may be lifted and the door
released.
Improvements in the oil pump relate chiefly to the lower valve in the chambered
stopping bar, and to the method of securing a bottom to the chamber. It relates
also to means for preventing the oil when it falls from the pump spout from spattering
back of the pump.
'
Referring to Figures 22 and 23, it will be seen that the chamber is enlarged for.
the reception of the valve h". The bottom i is a plate, with a central opening
and grooves across its under side. These latter serve to admit oil to the pump
chamber, and to receive the fastening wires j", ". These wires extend across the
plate, and are secured by being wrapped around lugs or pins on the sides of the
chamber, as indicated in Figures 21 and 23.
The valve is a disc which fits somewhat loosely into the enlarged chainber, the
shoulder formed by the enlargement limiting its lift. This valve has holes or aper-
tures (see Figure 23), which do not coincide when the valve is seated with the
aperture in the seat or bottom plate ¿¹¹, but when the valve is lifted the oil is free
to pass up through both.
J
Referring to Figures 24, 25, and 26, the first shows a cross section, and the two
latter show respectively the upper and under sides of the bearing eap E", which
rests upon the journal.
In the shell of the cap is formed a recess k¹, into which the oil from the pump
spout falls; from this extends a channel or channels ", which lead the oil to
openings m", which communicate with a channel or channels n¹¹ in the lining of
the bearing.
.
By this arrangement the oil is first delivered to the journal at the inner or back
end, and from thence finds its way to the front again.
At ol is a notch or outlet from the recess k", which permits some portion of the
oil to find its way down the groove p" in the stopping bar, and on to the face of
the axle button.
Should any oil escape from the recess and channels in the cap, it will find its
way into an overflow channel q¹¹ around the margin of the cap, which will lead it
to the front.
The head of the vibrating pump is housed in on three sides by the chambered
stopping bar C, and its nozzle or spout vibrates between two adjacent lugs on the
housing walls. This prevents the oil from flying or splashing back of the pump,
and ensures the spray all entering the pump. The spout should be arranged to direct
the jet towards the inner end of the cap, so as to spatter as little as possible.
F is a lever shoe, the inner end of which catches underneath a flange on a dust-
excluding half collar G₁ in such a manner as to keep the latter snugly pressed.

page_text: against the re-inforce on the axle. The outer or front end of the shoe is adapted
to engage the sloping front of the housing, so as to drive the shoe to the back, and
thus keep the collar G" pressed closely against the back wall of the housing.
By reference to Figure 21 it will be seen that the nose of the shoo is rounded and
fitted to engage the hollowed fillet on the collar. This collar is adapted to catch
and return to the well such oil as may be thrown or collect upon the re-inforce.
The shoe F is hollowed out and provided with an overhanging lip. The purpose
of this is to catcb, deflect, and throw back the oil to the well should it be thrown
inward by the lateral swaying or surging of the car. The upward play of the
front end of the shoe may be limited by stops on the bar C", or upon the
housing.
In addition to the collar G" I contemplate using a dust-excluding device, located
outside of the housing and around the re-inforce, similar to one described in a former
Patent granted to me. H", H", are the bars or straps of the truss, I" is the car
axle, and J, J", represent the wheels.
