COMPLETE SPECIFICATION (AMENDED).
"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
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 car trucks intended more especially for electric railway
service, and the object of the invention is to improve that type of car truck known
as the maximum traction truck in which each swiveling truck is provided with two
driving wheels and with two pilot wheels. In practice the car is mounted upon two
trucks, and the trucks are equipped with suitable brake appliances capable of
being operated from either platform of the car so as to apply the brakes to the
wheels of both trucks simultaneously.
My
improvements-inelude-means-for-obtaining--increased--traction-on-the-driving
wheels-and-for-automatically-adjusting--the--weight--of--the--ear--body-on--the-pilot
wheels-when-running-through-eurves:
The construction which I have adopted provides for a swinging bolster to which
the car body is pivotally connected, the bolster being supported on a combination of
spiral and elliptic springs which give the same easy inotion of car body that is
obtained with swing-bolster swiveled trucks, while at the same time providing more
weight on the driving wheels.
Preferably the truck will be provided with 33" driving wheels and 20" pilot
wheels for closed car work. The size of the pilot wheels permits them to swing
under the sills of closed cars or the steps of open cars.
The bolster is provided with king pin and swivel plates so that when the car
body is mounted on the trucks the point upon which the truck turns in curving
will be fixed, thus obviating the wear incident to the play of the trucks under the
car body and the kicking of the brakes, objectionable features in all previously
constructed maximum traction trucks.
When-the-car-body-is-mounted-on-the-trucks the weight-is--earried-on-side-plates
elastically-supported-on-the-truck-frame-and-working-under-suitable-rub-plates-pro-
vided-on-the-ear-body.
A-leading feature-st-my-invention-comprises-the--means--whereby--the-weight-for
the-pilot-wheels--is-automatically--adjusted. For--this--purpose-I-preferably-use--a
drum-or-roller-co-operating-with-a-track, these-parts-being located-at-that-end-of-the
track-which-earriss-the-pilot-axle-and--being--there--fixed--respectively--to-the-trnele
frame-and-the-bottom-of-the-ear-body-as--hereinafter explained. Various-modifica-
tions--in-the---form--of--these---appliances -rare--practicable,---some--of-which--are

The truck is especially designed with a view of securing great strength and
onduranco and it embodies peculiar and novel features and combinations as will
horeinafter appear.

Referring now to Figares 9, 10-and-11-ef the drawings. 4, 4", indicate the pedestals
which are connected together by the upper duplex beauis 5 and the lower
beams (both sides of the truck frame being in all respects, the same), and
7, 7, are the journal boxes. The pedestals 4 are provided in their top members
with recesses to receive spiral springs S which seat on top of the journal
boxes 7 to spring-cushion the truck frame at that point, and on the tops of
tho journal boxes 7° aro scated the spiral springs 8 which extend between the
members of beain 5 and bear against the top members of the pedestals 4",
thus spring cushioning the truck frame at that point. The duplex beams 5 aro
riveted in channels formed in the sides of the top members of the pedestals 4"
and extend beyond the pedestals, such extensions being supported by the under
truss beans 9 riveted to beams 5 and to the bottoms of pedestals 4. To the
outside of pedestals are riveted the duplex end beams 10 supported from below
by the truss beans 9 which are riveted to the bottoms of pedestals 4 and to snid
beams 10. At the bottom of the pedestals are secured the removable
repairing pieces 11.
The duplex benins 5 and 10 aro carried around at the ends of the truck and
extend transversely of the truck, with their members 5 and 10 respectively in
contact, and serve to strengthen the structure at those points; and to each end of
the truck there is riveted an angle beam 12. By forming the duplex beams 5
of continuous pieces extending from pedestals 4 beyond the pedestals at the
pilot wheels, to which latter pedestals said beams are independently riveted, and
continuing said beams transversely at the end of the truck without break, there is
afforded superior strength to the structure.
The side frames of the truck are connected together centrally by the transverse
tie-beam 13 of a depth corresponding to the space between boams 5 and 6, and is
riveted to said beams, thus serving to hold the side frames in proper alignment.
The driving wheels are indicated at 14 and their axle at 14, and the pilot wheels
at 15 and their axle at 15ª.
The bolster 16 which is elastically supported is provided with the usual
swivol connections to receive the car body and is swung from links pivoted to

page_text: transoms supported on the duplex boatns 6. The transoms 17 are arranged noar
tho pedestals 4 so as to bring the bolster 16 which is supported thereby near
the axle of the driving wheels thus placing a larger percentage of the load on
the driving wheels than on the pilot wheels. The transoins are rivoted to
plates 18 which in turn are riveted to the duplex beams 5. The bolster 16 is
suspended between the transoms 17 which serve as a guide for it and prevent
it from moving in a direction longitudinal with the car.
The means for olastically supporting bolster 16 and affording to it a limited
swinging movement transverse of the truck, comprise the spring plank 18
having end brackets 18 to which are pivoted the lower onds of four links 19
the upper ends of said links being pivoted to the upper bearings of rubber
springs 19 which are suitably mountod upon the transoins 17 as shown. Tho
links 19 have normally a slight outward inclination, as seen in Figuro H, the
effect of which is to raiso that sido of the car body toward which the bolster 16
noves when the truck runs into a curvo, thereby giving the effect of an additional
super-elevation of the outside rail of the curve. The spring plank is provided
with pockets 20 in which sent the spiral springs 21 whose upper ends seat in
pockets 22 secured to the bottom of the bolster 16. Between the spiral springs 21,
one near each end of the spring plank, there is arranged a half elliptic spring 23
whose ends rest in sockats 23 on the spring plank, the said spring 23 being
connected to the bottom of the bolster 16 by a suitable elliptic spring-socket 23.
The motor for propelling the truck is indicated at 24 and it is sleeved on the
axle 14 of the driving wheels in any approved manner, with its opposite end sup-
ported by the bar 25 which rests on spiral springs 26 suitably arranged in
brackets 27 which are riveted to the transverso duplex beams 10° at that end of the
truck. The weight of the motor augments the traction on the driving whools.
At that end of the truck outside the pilot wheels there is secured to the anglo
bar 12 the plane track 28 preferably in the form of a sector of a circlo whose centre
is the swivel connection 16 betwooh the truck and the car body, its central portion
being on the longitudinal axis of the truck. To the car sill which is indicated at 29
is fixed a bolt 30 screw-threaded below its point of attachment to the car sill and
provided with a pocket 31 and a nut 32 on said screw-threaded portion, which nut
may be screwed up or down to increase or decrease the tension of spiral spring 33
which at its bottoin seats in a pocket 34 resting on the housing 35 whose upper
oxtonsion is surrounded by the spiral spring 33 and in whose lower extension is
journaled the roller 36 which is adapted to travel on tho track 28 as the truck
swivels under the car when running through a curve.
By turning the nut 32 the tonsion on spring 33 may be increased or decreased
as desired so as to increase or decrease the pressure of the roller 36 on its
track 28. By this means the desired amount of weight is socurod on the
pilot wheels and the traction on the driving wheels regulated as required.
Instead of fixing tho bolt 30 in the car sill, it may be securod to the lower
pocket 34 and work loosely in a threaded bearing socured to the said sill and shown
in Figure 4. In this case the upper pocket for the spring is threaded internally to
engage the threaded bearing and is provided with means, such as recesses or pro-
jections, whereby it may be turned to adjust the tension of the spring.
The braking appliances are not illustrated in the prosont caso, but they will be of
such character as to porinit the application of most of the pressure on the driving
wheels and only an aimount on the pilot wheels in proportion to the weight carried
by the latter. This will provent skidding and flattening of the pilot wheels.
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:
