Improvements relating to Railway and like Vebicles.
I, EDGAR PECKHAM, of 20 Cortlandt Street, in the City and 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:-
This invention relates to improvements in car trucks particularly intended for
heavy elevated or suburban electric cars. It is also adapted for cable and other
street railways.
The truck relates to the class known as double trucks employed for supporting
long car bodies, the car body being mounted upon a pair of the trucks which are
equipped with compound brake lever appliances.
The object of the present improvements is to provide a truck particularly
adapted for supporting heavy cars made use of in high speed service, and the parts
are therefore heavily constructed.
My improvements comprise a certain novel construction of the side frames
intended to afford great strength to the truck and render it capable of sustaining
the weight of the car body mounted upon a center-bearing bolster; also novel
means of supporting the center-bearing swing bolster on the truck; also novel
means of obtaining increased traction on the driving wheels of the truck, and
also means for ensuring an even application of the brakes when running through a
curve.
My present improvements are illustrated in the accompanying drawings which
form part of this specification and wherein like parts are indicated by like
numerals of reference in the several views and wherein,
Figure is a plan view of the truck embodying the invention.
Figure 2 is a side elevation of the truck shown in Figure 1.
Figure 3 is a longitudinal sectional view on the line 3, 3, of Figure .1, certain
parts being broken away.
Figure 4 is a transverse sectional view on the line 4, 4 of Figure 1.
Figure 5 is a side elevation of a truck illustrating certain features hereinafter
described.
Figure 6 is a plan view of Figure 5, and
Figures 7 to 13 show details pertaining to Figures 5 and 6.
Referring to the drawings, it will be seen that the side frames comprise the
yokes or pedestals 14, upper longitudinal beams 15, preferably duplex as shown,
and which connect the yokes 14 together near the center of their vertical height,
and lower longitudinal beams or trusses 16 connecting said yokes together at their
bottoms also end beams 17 connected to the yokes at the front on the same plane
as beams 15, and the under truss beams 18 extending from the outer lower ends of
the yokes 14 upward to the end beams 17.
The truck has a short wheel-base, and the side frames are constructed to afford
great, strength, the beams consisting of soft steel hot riveted to soft steel pedestals
into which the upper beams are inlaid before riveting. The lower beam 16 is
secured by rivets in pockets cast in the lower sections of the pedestals. Between

page_text: the lower and upper beams 15 and 16 of each side frame is secured a bridge
truss 19 rivuted to said beams and braced against the lower sections of the pedestals.
The side frames trussed as shown renders it possible, in a truck having longitudinal
beatus commeering the pedestals together, to locate the car body supporting bolster
at the center of the wheel-base, the bridge truss giving to the side frames the
requisite strength to sustain the weight of the car body with safety.
Within the yokes 14 the journal boxes 20 are arranged to operate in the usual
manner, and above the tops of the journal boxes are placed spiral springs 21, us
shown in dotted lines, Figure 2, the said springs entering recesses in the top
member of the yokes 14, and serving to spring-cushion the truck on the journal
boxes and thus assist in preventing the pounding of the rail joints. The axles of
the truck are indicated at 22 and the wheels at 23.
At the longitudinal center of the truck frame there is located the swing bolster 24
composed of two channel bars set on edge and held together by being riveted to
the hearing plates 25, the swivel plate 26. land the spring sockets 27. The
bolster 24 is carried upon the spring plank 28, being supported thereon by a
system of springs comprising the half elliptic spring 29 and the spiral nest
springs 30. The half elliptic spring 29 has its ends loosely seated in pockets 1
and is provided centrally with a strap 32 having a concave depression in its top
which receives a convex bearing 33 attached at the bottom of the swing bolster,
thus providing a flexible connection between the holster, and said spring. Spring
cups 27 to receive the spiral nest springs are also provided on the spring plank 28
and are preferably formed integral with the pockets 31 for the half elliptic spring.
The bolster of the car may be provided with side hearing plates adapted to rest
on the hearing plates 25 of the swing bolster 24 to admit of a limited rocking
motion of the car, governed by the stiffness of the spiral nest springs 30, and thus
greatly to the case of riding since it permits the wheels on one side of the
truck to rise independently of the car body.
a
The spring plank 28 is suspended by four links 34, two at each side of the truck,
the links being carried by the two transverse bars or transoms 35 which rest in
pockets 36 in the side beams 15 of the truck frame. The transverse bars or
transoms 35 are rigidly bolted to the side beams 15 and thus serve to hold the
transverse end beams 36 of the truck frame in rigid alignment. The transverse
bars or transoms 35 also serve as a guide for the swing bolster 24 preventing it
from moving in a direction. longitudinal with the car.
To the transverse bars or transons 35 are also riveted pocket 87 which receive
the spiral springs 38 upon which rest. the support 39 for the nose of the motor.
The four links 34 have normally a slight outward inclination as shown in
Figure 4. The effect of this is to raise that side of the car body ward which the
bolster 24 moves when the truck passes onto a curve, thus giving the effect of an
additional super-elevation of the outside rail of a curve.
The brake rigging is fitted with flat bruke beams 40 equipped with the brake
shoes 41. The brake shoes 41 are pivoted to links 42 which are in turn pivoted
to brackets 43 supported on the imusverse end beams 36. To the inner sides of
the brake shoes at one end of the truck, there are pivotel, at each
side of the truck, the upright levers 44 and to the heads of these
levers is secured the equalizer or floater 45. The floater 45 is provided
with a segmental piece 46 on which the rod 47 (leading to the sway bar secured
to the bottom of the car at its longitudinal center) works through a roller 48
journaled in the strap 49 embracing the floater 45 and segmental piece 46, the
Said roller 48 being so mounted with relation to the inner segmental curve of the
piece 46 as to ensure an even application of the brakes when the car, mounted upon.
the pair of trucks, is rounding curves.
The means for obtaining increased traction on the two wheels supporting the
motor, known as the driving wheels, will be seen in Figures 5 to 13. In Figures 5
and 6 the holy supporting springs 50) are of the half elliptic type and have their
lands seated in pockets 51 on the side beams 15 of the truck frame and are con-

page_text: nected to the center bearing bolster 52 upon which the car body indicated at 53
rests. Spiral springs may of course be employed in lieu of the half elliptic
springs for supporting the bolster on the truck.
At one end of the truck frame, preferably the inside end, its transverse beam 36
is provided with the bracket 54 having an elongated portion serving as a guide
for bolt 55 which is connected by a sirap or frame 56 to the half elliptic spring 57.
In the frame 5, centrally over the top of the half elliptic spring 57, is journaled
the roller 58 which is adapted to come in contact with a plate or bolster 58"
attached to the under side of the car body.
The ends of the half elliptic spring 57 seat in pockets 59 riveted to the end
bean 36. These pockets 59 may be made in various ways with a view of rendering
them adjustable so that the height of the surface upon which the ends of the half
elliptic springs seat may be increased or decreased as desired, to increase or decrease
the tension upon the half elliptic spring 57. In Figures 8 and 9 the pockets 59
are adapted to receive a series of plates 59" so grooved as to interlock with the
inside surface of the pocket, and also with one another, and thus prevent their
displacement. In Figure 10 the shank of the pocket 59 is provided with a series
of holes to adapt it to be connected to the end beam 36 at different elevations. In
Figures 11 to 13 the device is made in two parts, one part 59 being riveted to
end beam 36 and adapted to receive the shank of pocket 59°, and be secured in
place by a bolt as shown. The pocket 59°, thus formed, is easily removable and
between it and the fixed part 59, there is placed a washer of indurated fibre 60
as shown. With a series of pockets 59° of varying heights the desired tension on
Spring 57 may be obtained by selecting a pocket of the requisite height. With
these several forms of pockets, which are modifications of one another, the tension
on the half elliptic spring 57 may be varied as desired and thus the traction on
the truck wheels regulated.
It will be observed that the traction regulating appliances are located outside
the wheels of the truck, at the extreme end of the truck. By this arrangement, in
a truck equipped with a center bearing bolster, weight is trown on the end of the
truck outside the wheels which are between the bearing of the bolster and the end
of the truck frame, thus rendering it possible, by suitable adjustment of the tension
of the half elliptic spring of the traction regulating appliances, to put about
75 per cent. of the traction on said wheels, and without interfering with the
freedom of action of the car body.
It will further he observed that the motor is suspended from the axle of the
pair of wheels which is between the center-bearing bolster and that end of the
truck upon which the traction-regulating appliances are secured.
By this arrangement 'the greatest amount of traction is obtained on the driving
wheels, located between the two points indicated, as they thus receive in addition
to the weight of the car-body the weight of the motor.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. In a car truck, a side frame comprising a pair of pedestals and upper and
lower longitudinal beams connecting the pedestals together and a bridge truss

"Improvements relating to Railway and like Vehicles"
I, EDGAR PECKHAM, of 26 Cortlandt Street, in the City and State of New York,
United States of America, Manufacturer, do hereby declare the nature of this in-
vention, and in what manner the same is to be performed, to be particularly

My present improvements are illustrated in the accompanying drawings which
form part of this specification and wherein like parts are indicated by like numerals
of reference in the several views, and wherein, Figure 1 is a plan view of the truck
embodying the invention. Figure 2 is a side elevation of the truck shown in
Figure 1. Figure 3 is a longitudinal sectional view on the line 3, 3, of Figure 1,
certain parts being broken away. Figure 4 is a transverse sectional view on the
line 4, 4 of Figure 1. Figure 5 is a side elevation of a truck illustrating certain
features hereinafter described. Figure 6 is a plan view of Figure 5, and Figures 7
to 13 show details portaining to Figures 5 and 6.
Referring to the drawings, it will bo seen that the side frames comprise the
yokes or pedestals 14, upper longitudinal beams 15, preferably duplex as shown,
and which connect the yokes 14 together near the center of their vertical height,
and lower longitudinal beams or trusses 16 connecting said yokes together at their
bottoms; also end beams 17 connected to the yokes at the front on the same plano
as beams 15, and the under truss beams 18 extending from the outer lower ends
of the yokes 14 upward to the end beams 17.

page_text: The truck has a short wheel-base, and the side frames are constructed to afford
grent strength, the beams 'consisting of soft steel hot riveted to soft steel pedestals
into which the upper beams are inlaid before riveting. The lower beam 16
is secured by rivets in pockets cast in the lower sections of the pedestals. Between
the lower and upper beams 15 and 16 of each side frame is secured a bridge truss 19
riveted to snid beams and braced against the lower sections of the pedestals.
The side frames trussed as shown renders it possible, in a truck having longitudinal
beamus connecting the pedestals together, to locate the car body supporting bolstor
at the center of the wheel base, the bridge truss giving to the side frames the
requisite strength to sustain the weight of the car body with safety.
Within the yokes 14 the journal boxes 20 are arranged to operate in the usual
manuer, and above the tops of the journal boxes are placed spiral springs 21, as
shown in dotted lines, Figure 2, the said springs entering recesses in the top
member of the yokes 14, and serving to spring-cushion the truck on the journal
boxes and thus assist in preventing the pounding of the rail joints. The axles of
the truck are indicated at 22 and the wheels at 23.
At the longitudinal center of the truck frame there is located the swing bolster 24
composed of two chanuel bars set on edge and held together by being riveted
to the bearing plates 25, the swivel plate 26, and the spring sockets 27. The
bolster 24 is carried upon the spring plank 28, being supported thereon by a
system of springs comprising the half elliptic spring 29 and the spiral nest
springs 30. The half elliptic spring 29 has its ends. loosely seated in pockets 31
and is provided centrally with a strap 32 having a concave depression in its top
which receives a convex bearing 33 attached at the bottom of the swing bolster,
thus providing a flexible connection between the bolster and said spring. Spring
cups 27' to receive the spiral nest springs are also provided on the spring plank 28
and are preferably formed integral with the pockets 31 for the half elliptic spring.
The bolster of the car may be provided with side bearing plates adapted to rest
on the bearing plates 25 of the swing holster 24 to admit of a limited rocking
motion of the car, governed by the stiffness of the spiral uest springs 30, and thus
add greatly to the ease of riding since it permits the wheels on one side of the
truck to rise independently of the ear body.
The spring plank 28 is suspended by four links 34, two at each side of the truck,
the links being carried by the two transverse bars or transons 35 which rest in
pockets 30* in the side beams 15 of the track frame. The transverse bars or
transoms 35 are rigidly bolted to the side beans 15 and thus ɛerve to hold the
transverse end benuus 36 of the truck frame in rigid alignment. The transverse
bars or transoms 35 also serve as a guide for the swing bolster 24 preventing it
from moving in a direction longitudinal with the car.
To the truusverse bars or transoms 35 are also riveted pockets 37 which receive
the spiral springs 38 upon which rest the support 39 for the nose of the motor.
The four links 34 have normally a slight outward inclination as shown in Figure 4.
The effect of this is to raise that side of the car body toward which the bolster 24
moves when the truck passes outo a curve, thus giving the effect of an additional
super-elevation of the outside rail of a curve.
The brake rigging is fitted with flat brake beams 40 equipped with the brako
shoes 41. The brake shoes 41 are pivoted to links 42 which aro in turn pivoted to
brackets 43 supported on the transverse end beams 36. To the inner sides of the
brake shoes, at one end of the truck, there are pivoted, at each side of the truck, the
upright levers 44 and to the heads of these levers is secured the equalizer or floater 45.
The floater 45 is provided with a segmental piece 46 on which the rod 17 (loading to
the sway
bar secured to the bottom of the car at its longitudinal center) works through
a roller 48 journaled in the strap 49 embracing the floater 45 and segmental piece 46,
the said roller 18 being so mounted with relation to the inner segmental curve of the
piece 46 as to ensure an oven application of the brakes when the car, mounted upon
the pair of trucks, is rounding curves.

page_text: The means for obtaining increased traction on the two wheels supporting the motor,
known as the driving wheels, will be seen in Figures 5 to 13. In Figures 5 and 6
the body supporting springs 50 are of the half elliptic type and have their ends seated
in pockets 51 on the side beams 15 of the truck frame and are connected to the
center bearing bolster 52 upon which the car body indicated at 53 rests. Spiral
springs may of course be employed in lieu of the half elliptic springs for supporting
the bolster on the truck.
At one end of the truck frame, preferably the inside end, its transverse beam 36
is provided with the bracket 54 having an elongated portion serving as a guide for
bolt 55 which is connected by a strap or frame 56 to the half elliptic spring 57. Io
the frame 56, centrally over the top of the half elliptic spring 57, is journaled the
roller 58 which is adapted to come in contact with a plate or bolster 58 attached to
the under side of the car body.
The ends of the half elliptic spring 57 seat in pockets 59 riveted to the end beam 36.
These pockets 59 may be made in various ways with a view of rendering them ad-
justable so that the height of the surface upon which the ends of the half elliptic
springs seat may be increased or decreased as desired, to increase or decrease the
tension upon the half elliptic spring 57. In Figures 8 and 9 the pockets 59 are
adapted to receive a series of plates 59 so grooved as to interlock with the inside
surface of the pocket, and also with one another, and thus prevent their displacement.
In Figure 10 the shank of the pocket 59 is provided with a series of holes to adapt it
to be connected to the end beam 36 at different elevations. In Figures 11 to 13 the
device is made in two parts, one part 59' being riveted to end beam 36 and adapted
to receive the shank of pocket 59°, and be secured in place by a bolt as shown.
The pocket 59, thus formed, is easily removable and between it and the fixed
part 59, there is placed a washer of indurated fibre 60 as shown. With a series of
pockets 59 of varying heights the desired tension on spring 57 may be obtained by
selecting a pocket of the requisite height. With these several forms of pockets,
