I SAMUEL DAVIS, of 47 Cote Street, in the City and District of Montreal, Province
of Quebec, and Dominion of Canada, 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 has for it's object to prevent the trucks "slowing" or turning to a
greater extent than demanded by the maximum curvature of the track, so that in case
of derailment the truck will be kept under the car in running position. In this my
invention the car-truck, near it's end, is joined to the under side of the car body by
pieces of wire rope extended longitudinally of the car, the combination of the parts
and their construction and operation becoming such as to permit the car-truck to turn
under the car-body sufficiently to enable the truck to "slew or turn for the
maximum curve in the track, and thereafter serve as stops, or checks to any further
turning.
By the employment of a wire rope having flexibility, (instead of a rod, which has
heretofore been used,) I am enabled to secure greator strength in the connections, and
and at the same time have connections less liable to be bent or wrenched asunder by a
blow or sudden strain. I have also provided the truck and car with a set of auxiliary
connections, which supplement the action of the main connections, when, for instance,
a wheel meets a sleeper, or some other obstruction on the track.
Figure 1. is an under side view of a sufficient portion of a railway car to enable my
improvements to be understood; Figure 2. a side elevation of a portion of the car
shown in Fig. 1., and Figure 3. is a detail to be referred to.
The car-body A, truck B, pivoted at C, and having wheels D, are, and may be as
usual. The truck has bolted to it, at or near it's corners, brackets or stands a, having
strong bolts a', with which is engaged one end of each of the connections a², made of
strong wire rope or cable, the opposite ends of the said connections, as herein shown,
being extended through or suitably attached to a slotted metallic loop or eye, as a³,
fitted to slide to a limited extent on a strong bolt as, extended through the ears of a
stand, a bolted to the frame work of the car-body, the length of the slot in the loop
or eye forming a part of the wire rope being sufficient to permit the truck to turn

page_text: under the car body to accommodate the truck to the maximum curvature of the track
on which the truck is to run.
In case of an obstruction on the track, or the derailment of the truck, or the
striking of a wheel against a tie, the longitudinally arranged connections between
the car-body and truck prevent the latter slewing about, and as the truck cannot
slew it must keep it's leading end forward in running position.
The blow of the wheel of a rapidly running car against an obstruction on a
track or against a tie is very great; so to afford additional security and safety I
have added to the car an auxiliary set of connections, as b, also preferably mado
of wire rope, so constructed, or attached at opposite ends to the car-body and truck
as to permit the truck to turn under the car-body for a determined distance, and
then act as stops to any further turning of the truck.
The auxiliary connections b, are joined to the stands b', 62, or bolts thereon
attached, respectively, to the truck and car-body.
In Figure 4, I have shown an alternative method of effecting the object of my
invention. Upon the frame work of the car body is a plate E, securely bolted down,
and having a projecting stud F, having a wide key-way G. Upon the said stud F
is the crank arm H, in which is fitted the feather , which is adapted to work in the
koyway G. By this means the crank arm is allowed to swing a limited distance,
determined by the width of the key way G, thus answering the purpose of the slotted
loop a³ Fig. 3.
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. The car-body, the stands a³, containing bolts, and attached to the car body
near it's sides, the truck and it's attached stands a', and bolts a, combined with
slotted metallic loops or eyes a³, and with the two independent longitudinally arranged
flexible connections a², composed of wire rope operatively joined, respectively, to
the truck, and to the car-body, to permit the truck to swing and accommodate itself
to the maximum curvature of the track, and thereafter serve as stops to prevent
further turning of said trucks, substantially as described.
2. The car-truck, and the car-body pivoted thereto, combined with two sets of
flexible connections, a, b, composed of wire rope having attached slotted eyes, and
extended longitudinally from the truck in opposite directions, and connected, substan-
tially as described, to the car-body, and to the corners and sides of the truck, to
operate all substantially as described.
3. The car-truck and car body pivoted thereto in combination with the plate E
bolted thereto, the stud F having key way G, and the crank arm H, having the
feather, all substantially as described.
