Improvements in Side Frames for Railway Vehicle Trucks.
1, HERBERT HILLS HEWITT, of No. 743 Elmwood Avenue, in the City of
Buffalo, County of Erie, State of New York, United States of America,
Manufacturer, do hereby declare the nature of this invention, and in what manner
the same is to be performed, to be particularly described and ascertained, in
and by the following statement:-
The present invention consists, primarily, in providing a car-truck, the side
frames of which are furnished with bifurcated ends forming open-ended spaces, with
pedestals that are formed each with two vertical jaws connected by a top plate,
but open at the bottom for receiving the oil-box (and springs if desired).
A further feature of the invention consists in forming the pedestal with a
spring-cap in piece with the side jaws and top of the pedestal.
The invention further consists in various features of improvement hereinafter set
forth, illustrated in the accompanying drawings, and particularly defined in the
several claims at the end of this specification.
Figure 1 is a view in side elevation of the side frame.
Fig. 2 is a view in side elevation of the side frame with the pedestals in place.
Fig. 3 is a plan view of the side frame, showing the portions of the bolster
attached thereto.
Fig. 4 is an end view of a side frame with the pedestals in place.
Fig. 5 is a view in vertical cross-section through the side frame at the center of
the pedestals.
Fig. 6 is a view in horizontal section through the end portion of the side frame
and one of the pedestals.
The side frame is shown as formed from a plate-girder or beam of metal
(preferably steel) that is rolled to the shape shown in Fig. 1 of the drawings; that
is to say, the side frame has a central web or body A, the top and bottom edges of
which are thickened, preferably by lateral flanges a, preferably on both sides, and
beyond these lateral flanges are formed the vertical reinforce-ribs a'. The end
portions of the web or body A are cut away to form the spaces to receive the
pedestals wherein the oil-boxes (and preferably also the springs) of the trucks in
such manner that the pedestals can be withdrawn horizontally or endwise from the
side frames for the purpose of repairing or replacing parts.
In the preferred practice of my invention each of the pedestals consists of the
inner and outer vertical sides or jaws B and B', that are united together by the
top portion B2, and preferably these parts are formed from a single casting.
The bottom of each pedestal is left open to receive the oil-box, &c., but when the
pedestal is set in place within the side frame the bottom of the pedestal will be
.

page_text: closed by the corresponding projecting part at the end of the side frame.
Preferably, although not essentially, each pedestal has its inner jaw provided
with flanges b, between which will be received the end of the web or body A of
the side frame, and suitable bolts c will removably connect the pedestal to said web
or body. By preference also the top B2 of each pedestal is formed with vertical
rihs 6, that will extend at each side of the upper projecting arm or portion at
the end of the truck-frame, and similar projections 6 are shown as formed at the
lower ends of the pedestal-jaws in order to more securely retain these ja vs in
position upon the lower projecting portion of the side frame. Through the outer
jaw of each of the pedestals is formed a vertical hole to receive a retaining.
bolt D, that will pass through the reduced ends of the top and bottom projecting
portions of the side frame, suitable, nuts d being used to retain the bolt D
securely in place. By preference each of the pedestals has formed in piece with
its top and jaws a cap B³ to receive the upper end of the spring that is interpose 1
between the pedestal top and the subjacent oil-box.
In placing the parts in position for use the truck-frame is first adjusted to the
proper height in the horizontal position, and the pedestals are then placet
over the oil-boxes (as are also the springs when springs are used on top of such
boxes). The wheels are then rolled toward the truck-frame, the pedestals being
guided into the open-ended spaces formed by the bifurcated or projecting end
portions of the side frame. The pedestals are then secured in place by the bolts c
and by the through-bolt D, and the opening at the bottom of each pedestal is
closed by the lower projecting end portions of the side frame. It will thus be
seen that the lower ends of the pedestal-jaws are securely tied together and braced
by the projecting lower portions of the side frame, so that the necessity of using
separate parts for this purpose is avoided. By this means simplicity of structure
is obtained and the number of parts is reduced, and, moreover, greater strength is
given to the parts and the danger of their working loose is avoided. When the
wheels, axles, oil-boxes, or the like are to be removed for replacement or repair,
the trucks will be jacked up slightly, the bolts D and c will be withdrawn, and
the pedestals will be removed endwise from the side frames, thereby permitting the
oil-boxes, &c., to be removed from the bottoms of the pedestals.
с
Preferably the side frames of the truck will be connected together by a bolster
consisting of channel-bars E and E', the bent ends of which will be riveted, as
shown, to the web or body A of each of the side frames and the flanged edges of
which will be riveted to plates F, that in turn are riveted to the inwardly-projecting
flanges at the top of the side frame.
Having now particularly described and ascertained the nature of my said inven
tion and in what manner the same is to be performed, 1 declare that what I
claim is:
1. A side frame for car-trucks formed of a rolled beam having open-ended spaces
at its ends to permit the pedestals to be inserted into and removed horizontally
therefrom, in combination with three-sided pedestals formed with open bottoms
and removably held within the end spaces of the side frame, substantially as
described.
2. A side frame for car-trucks formed of a metal web, or body having top
and bottom thickened edge portions projecting from its ends to form open-ended
spaces for the pedestals within the end spaces of the side frame, the bottoms of said
pedestals being closed by the bottom thickened end portions of the side frame,
substantially.as described.
3. A side frame for car-trucks formed from a single rolled-plate girder or beam
having a thin web or body and having integral with said web or body top and
bottom thickened edges projecting at its ends, in combination with three-sided
pedestals removably held within the end spaces of the side frame, the bottoms of
said pedestals being closed by the bottom projecting thickened portions of the side
frame, substantially as described.

page_text: 4. A side frame for car-trucks comprising a metal web or body provided at its.
ends with top and bottom projecting portions forming pedestal-spaces, in com-
bination with three-sided pedestals formed with open bottoms, said pe lestals being
removably bolted to the web or body and to the top and bottom projecting end
portions of the side frame, substantially as described.
5. A side frame for car-trucks comprising a metal web or boly provided at its
ends with top and bottom projecting portions forming pedestal-spaces, in com-.
bination with three-sided pedestals provided at top and bottom with verticil
projections to engage the projecting end portions of the side frame, substantially
as described.
6. A pedestal for the side frame of a car-truck formed of a single piece consisting
of integral jaws or sides and top the inner jaw being flanged to engage the web.
and the top being flanged to engage the projecting end of the side frame and a
spring-cap formed in one piece therewith, substantially as described.
7. A pedestal for the side frame of a car-truck consisting of integral jaws or
sides and top the inner jaw being formed with double flanges to straddle the end
of the body of the side frame, substantially as described.
8. A pedestal for the side frame of a car-truck consisting of integral jaws or
sides and top, one of said jaws having a vertical hole therethrough to receive a
bolt and the other of said jaws being flanged to permit it to be attached to the-
body of the side frame.
