By the construction and arrangement of
parts described oil will be successively ap-
plied to the rails by lubricating devices at
the opposite ends of the car when the-latter
is traveling around a curve, thus insuring
effective and thorough lubrication. Also by
this construction and arrangement of de-
vices the rails will be lubricated irrespective
of the direction of movement of the car,
10 either end of which may travel forwardly
without the loss of efficiency in the lubricat-
ing operation, as will be readily understood.
The valve 11 in each pipe 9 and 10 has its'
stem provided with a' crank arm which is
15 coupled by a' connecting rod- 21 with the
lower end of a-lever 22 extending upwardly
through and pivotally mounted upon a plat-
form at the end of the car adj acent the pro-
jecting end of the particular supply pipe;
20 the upper end of the lever being so-arranged
as- to be conveniently manipulated by the
motorman, who may thus open and' close
the cut-off valve as occasion requires to pre-
vent discharge of lubricant when its use is
25 not necessary or desired.
Having thus described the invention what
we claim as- new is
1. The combination of a car having a
wheeled. truck pivotally mounted, a lubri-
30 cant feed' pipe extending transversely of and
mounted for swinging movement with the
truck, a lubricant reservoir, a supply pipe
extending therefrom to- said feed pipe, a
valve forming a pivotal' connection betweensaid pipes, said valve being governed by the 35
swinging movement of the truck to admit or
cut-off the flow of lubricant from the supply
pipe to the feed pipe, automatic means con-
trolled by the swinging movement of the
truck for supplying compressed air to the 40
lubricant reservoir, discharge devices car-
ried' by the feed pipe, a cut-off valve in the
supply pipe, and means for manually op-
erating said valve.
2. The combination of a car having a 45
wheeled truck pivotally mounted, a' feed
pipe extending transversely of and mounted
upon the truck to swing therewith' dis-
charge nozzles carried by the said pipe, a
lubricant reservoir, a, supply pipe extending 50
therefrom to said feed pipe, a valve forming
a pivotal connection- between said pipe and
automatically controlled- by the swinging
movement of the feed pipe to cut off or ad-
mit lubricant to. said pipe; an air reservoir' 55
having a valved connection with the lubri-
cant reservoir, a connection between the
valve thereof and the tr:'ck for automati-
cally opening and closing said valve; a cut-
off valve in the' supply pipe, and manually 60
operable means for controlling said valve.
In testimony whereof we affix our signa-
tures in presence of two witnesses.
