This invention appertains to liquid dispensers
and more particularly to a novel device for dis
pensing a measured quantity of liquid soap upon
each operation thereof by a user.
One of the primary objects of my invention is
to provide a liquid soap dispenser of the type
embodying a supporting bracket and a bowl orA
jar for the soap connected with the bracket and
having a novel pump mechanism for delivering
the soap from the bowl directly into the hand of
the user.
Another salient object of my invention is to
provide a novel pump mechanism for liquid soap
dispensers in which the necessity of packing
washers, gaskets and the like is eliminated, there
by insuring the effective operation of the pump
at all times.
i `
A further object of my invention is to provide

With these and other objects in view, the in

hereinafter more specifically described, claimed
and illustrated in the accompanying drawing, in 50

from the face plate I3 is the body portion I8 of
the bracket, and this body portion has formed
thereon and depending therefrom, an internally
threaded sleeve I0 for the reception of the neck
20 of the bowl or jar IIL The thread'ZI formed
on the neck of the bowl or jar Il can be inter
rupted as at 22 and a machine screw 23 can be
threaded into the bracket and into the inter-`
2,407,765
rupted portion of thel thread 2l so as to prevent
the accidental displacement, or removal by un
authorized persons, of the bowl Il from the
bracket.
The bracket has formed therein a ver
tically disposed filling opening 24 which corn
municates with'the interior of the sleeve I9, and
consequently with the bowl II. Hence, the bowl
can be filled through this opening without the
necessity of.~removing the bowlfromjthe bracket.
A novel closure plug 25 is provided for this opens»
ing, and this plug will be later described in de
tail. rllhe body portion 'I8 of the bracket also.
has formed therein a centrally disp’osedhori
zontal bore 26 which bisects the opening 24. This
bore 26 opens out both through the front and
rear of the body portion of the bracket. If de-`

Referring back to the filling plug 25, it will be
noted that the same includes a depending sleeve
42 and this sleeve has formed therein on oppo
site sides thereof spiral bayonet slots 43. In plac
ing the plug in position, the slots are placed over
the plunger 3l and upon the turning of the
filling plug, the plunger 3l will ride into the
recessed ends 4t of the bayonet slots d3.
This
will lock the plug in position and' discourage the
unauthorized removal thereof. The top wall of
the filling plug can be provided with Spanner
wrench openings 45 to facilitate the renewal
. thereof by an attendant.
From the foregoing description, it can be seen
that I have provided an especially simple and
durable liquid soap dispenser in which the neces
sity of packing gaskets and the like is entirely
be reinforced by side walls 21 which join with
