IMPROVEMENTS IN CAR AXLES
Year: 1887

page_text: I, EDGAR PECKHAM, of the City of Syracuse, County of Onondaga, and State of
New York, United States of America, Manufacturer, do hereby declare the nature of
my invention for IMPROVEMENTS IN CAR AXLES, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to the class of car axles which are provided with detachable
journal bearings of the form of sleeves slipped onto the ends of the axles for the
purpose of preserving the axle and admitting of renewing the journal bearings
thereof when required.
My present invention consists in an improved construction and combination of
parts which facilitate the removal of the journal bearings and are also adapted to
inore securely retain the same on the axle while in use.
The invention is fully illustrated in the annexed Drawing wherein Figs. 1, 2 and 3
are longitudinal sections of car axles embodying my improvements, Fig. 4 is a
detachably perspective view of the journal bearing, Fig. 5 is a perspective view of
the collar by which the said journal bearing is retained on the axle, and Fig. 6 is an
end view of the axle as constructed in the manner shown in Fig. 2 of the drawing.
Similar letters of reference indicate corresponding parts.
A-represents the car axle formed preferably of wrought iron,--B-denotes the
journal bearing which consists of a tube mounted detachably on the end portion of
the axle and is preferably composed of steel and case hardened.-C-represents a
collar which I rigidly secure to the end of the axle preferably by shrinking it thereon.
Said collar abutting against the end of the journal bearing-B-serves to securely
retain the same on the axle.
To prevent the journal bearing from turning on the axle [form the outer end
thereof with notches-n-n-or other suitable clutch face, and form the adjacent
face of the collar-with lugs or projections locking into the notches-n-
the journal bearing-B.
-n-of
"
To facilitate the removal of the journal bearing from the axle I taper the end
portion of the latter from the outer face of the wheel toward the end of the axle and
taper the interior of the tubular journal bearing-B-correspondingly. By drilling
J

page_text: a hole in the axle at the rear end of the journal bearing-B-as shown in Fig. 1
of the Drawing, and driving into said hole a wedge or key, the journal bearing-B-
is readily forced outward and loosened from its seat on the axle so as to permit of
readily removing said journal bearing.
'
The retaining collar-(-is to be previously removed from the axle by heating
said collar so as to expand it and loosen it on the axle sufficiently to permit of driving
the collar off from the axle.
The tapered end portion of the axle I prefer to terminate with a circumferentially
reduced nipple-D-and shrink the collar-C-on said nipple, thus requiring the
collar to be enlarged in thickness and imparting increased strength to the same.
The usual shoulder on the inner end of the journal bearing I form of a separate
collar F-which I also shrink onto the axle immediately back of the inner end of
the journal hearing--B-as represented in Fig. 3 of the drawing.
When the axle is thus constructed the car wheel will either have to be pressed onto
the axle before the aforesaid collar is shrunk on the latter, or the car wheel has to be
constructed with a hub which is detachable from the body of the wheel and divided
diametrically and clamped onto the axle. In order to obviate undue enlargement of
the journal bearings I form the axle with circumferentially rabbetted end portions-A-
as shown in Fig. 2 of the drawing and slip the tubular journal bearings onto the
said rabbetted portions of the axle.
On street car axles which require an extra collar on the extremity of the axle
I provide the free end of the nipple-D-with a circumferential rabbet-a-and
shrink on the rabbetted portion a secondary collar-C-which is sufficiently remote
from tho collar-C-to form the desired bearing--between them.
If desired to further insure the attachment of the secondary collar-C-to the
nipple D, a washer-d-of sufficient diameter to lap onto the exterior of the said
collar may be secured to the end of the nipple by a tap bolt passing through the
washer and into a screw threaded socket in the nipple as shown in Fig. 2 of the
drawing.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
-The combination of the axle-A-formed with the nipple-D,-the tubular
journal bearing-B-embracing the axle back of the nipple and provided with
notches-n-n, and the collar-C-permanently secured to the nipple and provided
with lugs or projections locking into the notches-n-n,-substantially as described
and shown.
2-The combination of the axle tapered from the outer faces of the wheels toward
the ends of the axle, tubular journal bearings mounted on the tapered end portions
of the axle and collars permanently secured to the ends of the axle and abutting against
the tubular journal bearings, substantially as described and shown.
3-The combination of the axle tapered from the outer faces of the wheels toward
the ends of the axle and terminating with the nipples-D-D,-the tubular journal
bearings-B-B-mounted on the tapered end portions of the axle and collars
permanently secured to the aforesaid nipples substantially as described and shown.
4-The combination of the axle tapered from the outer-faces of the wheels toward
the ends of the axle and terminating with the nipples-D-D-the tubular journal
bearings B-B-mounted on the tapered end portions of the axle, and collars
permanently secured to the nipples and of a greater diameter than the exterior of the
aforesaid journal bearings, substantially as shown and described.
5-The combination of the axle formed with tapered end portions terminating
with nipples-D-D,-tubular journal bearings--B-B-mounted on said tapered end
portions and provided with notches-n-n-at their outer ends, and collars-C-C-
permanently secured to the nipples and provided with lugs, locking into the aforesaid
noiches, substantially as shown and described.
-The combination with an axle of tubular journal bearings detachably mounted

page_text: on said axle and collars shrunk on the axle at opposite ends of each of said journal
bearings, substantially as described and shown.
7 The combination of an axle formed with tapering end portions, tubular journal
bearings formed cylindrical externally and tapered internally to correspond to the
end portions of the axle and detachably mounted on the latter and collars shrunk on
the axle at opposite ends of the said journal bearings, substantially as described and
shown.
8 The combination of an axle formed with tapering circumferentially rabbetted
end portions, tubular journal bearings tapered internally to correspond to the said
end portions of the axle and mounted detachably thereon and collars shrunk on the
ends of the axle and abutting against the ends of the aforesaid journal bearings,
substantially in the manner specified and shown.
9 The combination of an axle formed with tapering circumferentially rabbeted
end portions terminating with circumferentially reduced nipples, tubular journal
bearings tapered internally to correspond to the aforesaid end portions of the axle and
mounted detachably thereon, and collars shrunk on the nipples and abutting against
the ends of the said journal bearings substantially as described and shown.
10 The combination of an axle formed with circumferentially reduced nipples on
its ends, tubular journal bearings mounted detachably on the axles back of the
nipples, retaining collars shrunk on the nipples and abutting against the ends of the
said journal bearings, and secondary collars shrunk on the ends of the nipples remote
from the retaining collars, substantially in the manner set forth and shown.
