This invention relates to a lubricating system, and has
as its primary object the provision of an improved lubri
of which is connected to a ?exible tube 16 and 17.
One of the corner posts 12 is provided interiorly with
a plate-like support 18 through which extends an operating
handle 19 exteriorly of the front of the machine. By a
pull on operating-handle 19 certain of the parts of the
mechanism may be lubricated in a manner to be more fully

One of the most important points requiring lubrication
An additional object of the invention is the provision of
a lubricating system of this character which, by means of
internal connections with certain parts which require fre
quent lubrication, will enable the machine to be lubricated

for the main drive pulley. ‘conventionally, such a shaft
comprises a substantially solid shaft and in order properly
to lubricate the same, the pulley must be removed there
completely without the necessity of disassembly thereof.
