and more particularly to lubricant dispensers for
use with interchangeable factory-?lled lubricant
containers.

'
For the purpose of servicing a machine, differ-1‘
cut parts of which require di?erent types of
lubricant, it is desirable to be able to change the
lubricant supply to a dispenser or' ‘pump quickly
and easily. Where this can be‘ done a single dis
penser or pump can be used to perform in suc
cession a series of different lubricating opera
tions requiring different types of lubricant, thus
providing great-savings in investment and ‘space
over that required where a separate pump must
be provided for each operation.
One of the objects of the present invention is
to provide a lubricant dispenser which utilizes an
to appear later. A connecter plate I7 is secured til
to the body 5 concentrically with the stud l6 and
is formed at its outer periphery with a series of
slots and cam portions for making a bayonet con
nection with lugs i8 carried by an annular ?ange
I 9 on the body portion 20 of a magazine element. 10
The body portion-20 is formed with a central out
let opening' having a concave spherical wall as
indicated at 2| for sealing engagement with the
spherical surface of the inlet stud l6. An open
inlet tube 22 formed with screw threads on its 15
outer surface throughout its length is secured to
the bbdy portion in communication with the out
let opening and carries a piston 23 having a nut
24 for screw threaded engagement with the. tube
