WILLIAM C. MAYO AND JOHN HOULEHAN, OF EL PASO, TEXAS, ASSIGNORS OF ONE-THIRD
TO GEORGE EDWIN BRIGGS, OF EL PASO, TEXAS.
LIQUID-DISPENSING APPARATUS.No. 903,214.
Specification of Letters Patent.
Patented Nov. 10, 1908.
Application filed February 2, 1907. Serial No. 355,457.
To all whom it may concern:
Be it known that we, WILLIAM C. MAYO
and JoHN HOULEnAN, citizens of the United
States, residing at El Paso, in the county of
5 El Paso and State of Texas, have invented
a new and useful Liquid-Dispensing Appa-
ratus, of which the following is a specifica-
tion.
This invention has reference to improve-
10 ments in liquid dispensing apparatus, and
its object is to provide a means whereby
beverages or other liquids may be obtained
from the apparatus by a customer on the
deposition in the apparatus of a coin of
15 proper value.
To this end the invention comprises a suit-
able receptacle for the liquid to be dis-
pensed, means for ejecting from the appa-
ratus a predetermined quantity of the liq-
20 uid, a locking means for preventing the op-
eration of the apparatus except when a coin
of the proper predetermined value has been
introduced, which coin will release the lock-
ing mechanism and permit the liquid-eject-
25 ing mechanism to be manipulated by a cus-
tomer to an extent sufficient to cause the out-
flow of the liquid in a predetermined quan-
tity.
The invention further comprises a means
30 for presenting to the customer clean glasses
or other liquid receptacles, and means
whereby the used glasses may be automat-
ically cleansed and ultimately presented to
future customers, all by the operation of
35 the machine in the act of ejecting the liquid
to a customer.
The invention further comprises means
whereby the inserted coin is itself employed
for the operation of the lock mechanism
40 whereby the apparatus is released to the
manipulation of a customer; and means are
provided whereby any attempt of an un-
scrupulous person to work the machine by
a coin and then withdraw the latter will be*
45 prevented.
The invention will be clearly understood
from the following description taken in con-
nection with the accompanying drawings,
forming part of this specification, in
50 which,-
Figure 1 is a central vertical section of
tbe improved liquid dispensing machine,
with smie parts shown in elevation, and
with the parts in position to illustrate one
55 phase of the operation; Fig. 2 is a similarview of the portion of the machine contain-
ing the coin-operated mechanism, and show-
ing another phase of the operation of the ma-
chine; Fig. 3 is a cross section on the line
x-x of Fig. 1; Fig. 4 is a cross section on 60
the line y-y of Fig. 1; Fig. 5 is a section of
the coin conduit on the line z-z of Fig. 1;
Fig. 6 is a detail view of the operating pin-
ion; Fig. 7 is a detail view, partly in sec-
tion, showing a portion of the operating 65
mechanism for propelling the turn-table car-
rying the liquid-receiving receptacles; and
Fig. 8 is a detail view of the coin-engaging
end of the operating lever handle section.
Referring to the drawings, there is shown 70
a main casing 1 of cylindrical shape, the
bottom of which is supported upon an annu-
lar foot 2 having formed thereon so as to
surround the base an annular trough 3 de-
signed to receive waste liquid which will be 75
permitted to escape through a suitable ori-
fice, not shown. In the bottom of the casing
1. and concentric therewith is a pump cylin-
der 4 secured to the casing by screws 5, or
otherwise, and this pump cylinder has 80
formed in one side a conduit 6 which com-
municates with the interior of the pump
cylinder through an opening 7 at the lower
end thereof. This conduit 6 is continued up
above the pump cylinder and there carries a 85
valve 8 controlled by a spring 9, and the top
of the conduit is closed by a screw-cap 10
which also serves to confine the valve and.
spring in the conduit. Above the valve-seat
the conduit 6 communicates with a spout 11 90
screwed through the side of the casing into
a boss 12 formed on the side of the con-
duit 6.
Within the pump cylinder 4 there is a pis-
ton 13 provided with suitable packing rings 95
14, and through this piston is a passage 15
in which is located a valve 16 provided with
a valve head 17 seated in a suitable valve-
seat formed at the lower end of the passage
15. The stem of the valve 16 is guided by a 100
bracket 18 fast on the piston, and a spring
1.9, coacting with the bracket 18 and a head
20 formed on the valve stem, serves to main-
tain the valve head 17 normally against its
seat. The piston is carried on the lower end 105
of a piston-rod 21 which extends through
the piston and is there threaded to receive a
nut 22 which serves to clamp the niston
firmly to a flange 23 formed on the piston-
rod 21 near its lower end. 110
