LIQUID JSISI'ENSIN'G APPARATUS Original 1T0, 1,775,441, dated September 9, 1980, Serial 110.461422, filed June 16, 1930. Application reissue filed September 3, 1982. Serial No. 831,741.
This invention relates to apparatus of the type in which asoline or other liquid is delivered throng a flexible hose under control of a nozzle valve.
The objects of the invention are to provide simple, practical and efiicient mechanism for throwin a switch, or operating a valve or other from the nozzle end of the hose.
One of the important features of the invention is the provision of means by which pulling on the hose is made effective to operate the desired control mechanism.
Other novel features of the invention will appear as the specification proceeds.
The drawing accompanyingand forming part of the specification illustrates several difierent forms the invention may take, but it should be understood that the structure may otherwise vary without departure from the true spirit and broad scope of the invention. r
Fig. 1 is a general side view showing the invention incorporated in a'gasoline disensing pump or stand. Figs. 2 and 3 are roken details of the control means shown in Fig. 1; Figs. 4 and 5 are broken details illustrating other embodiments of the invention.
The resent invention is a continuation in part 0 applications 323,411, filed December 3, 1928, and 324,761, filed December 8,1928, and issued as Patents 1,713,102 of May 14, i 1929, and 1,717,274 of June 11, 1929, respeci tively.
In the first illustrated form of the invention, Figs. 1, 2 and 3, the control is efiected by means of hose 7 through the medium of an extensible or telescopic section rovided I at the upper end of the hose and s own as ow governing mechanism" for the pump motor will be operated to impel a flow of liquid through the supply pipe 12,
.In the second embodiment illustrated, the switch and valve are operated by a straight lever 22 connected by a link- 23 with a band '24 encircling the suspended'portion of the with a lever 29 operating a supply valve 30 in i the flow line and engaging the operating lever 31 of the switch 32, which controls the pump motor.
In all forms of the invention, it will be observed that the flow operation may be governed by simply pulling on the hose to start 'the fiow and by releasing pull on the hose to stop the flow. The natural efiect'of the hose to swing straight down from the goose-neck at the top will have a. tendency to restore the parts in Figs. 4 and 5, but this shutting ofi operation may be made certain by the suitable return springs 25 and 33. The parts may be arranged, so that pull on the swinging portion of the hose in any direction will be efiec tive to throw the switch or operate the valve, or both, so that the attendant may conveniently actuate the control no matter in what position he may be standing or no matter what position he may be in regard .to the pump stand. In constructions like those shown in Figs. 4 and 5, it will be evident, the same control may be effected by a push action on the hose toward the left in these views instead of a straight pull toward the left, so that the attendant may accomplish the same control ,eflects either by pulling toward the left or if he be at the right of the stand by pushing back on thehose, so as to effect the deflection on the hose as indicated in the dotted lines in Fig. 4. It will be understood therefore that the invention comprehends the deflection or shifting of the hose adjacent its supported end to effect mechanical actuation of the flow control mechanism, whether the latter be a switch or some other form of device. By this invention, the attendant at a pump stand is enabled to deliver continuously any desired volumes of liquid by simply operating the nozzle valve to start or to stop the flow and by using the hose in effect as a mechanical handle for throwing the switch or other control to start and stop the pump motor or the like, the meter at the pump stand at all times showing the amounts delivered in this way. The invention also involves a safety feature in that in the forms illustrated, the pump motor is automatically shut off as soon as the actuating pull on the hose is released. Inattention or carelessness on the part of the operator therefore. results in the flow being shut off. The terms employe'd herein are used in a descriptive rather than in a limiting sense, it being understood that equivalents may be employed as for in stance, in place of the return springs 18, 25 and 33, counter-balance weights, pressure actuated means or the like, may be used.
What is claimed is 1. A liquid metering and delivery system comprising a liquid delivery line terminating in a flexible hose, suspended for pulling movement and having a manually operable nozzle Y valve by which discharge of liquid from the hose may be accurately determined, an elecv tric pump for supplying liquid under pressure ;through said delivery line and hose, a meter in the delivery line for showing the amounts of liquid delivered by the hose under control of said nozzle valve, a switch for starting and stopping the electric pump and flexible mechanicalconnections from said susjpended pull portion of the hose to said switch for operating the latter to start and stop the pump by pulling movements on the hose, and whereby various desired quantities of liquid may be measured. and deliwlipd by control exercised at the nozzle end of the hose and the hose be drained by operation of the nozzle valve after shutting off the pump and the hose be left free of pressure after each delivery.
2A liquid metering and delivery system comprising a liquid delivery line terminating in a flexible hose, suspended for pulling movement and having a manually operable nozzle valve by which discharge of liquid from the hose may be accurately determined, an electric pump for supplying liquid under pressure through said delivery line and hose, a
meter in the delivery line for showing the amounts of liquid delivered by the hose under control of said nozzle valve, a switch for starting and stopping the electric pump and flexible mechanical connections from said suspended pull portion of the hose to said switch for operating the latter to start and stop the pump by pulling movements on the hose, and whereby various desired quantities of liquid may be measured and delivered by control exercised at the nozzle end of the hose and the hose be drained by operationeof the nozzle valve after shutting off the pump and the hose be left free of pressure after each delivery and valve means in said system connected to be actuated by said hose pull conber to said switch so that by pulling the said conduit outwardly from the stand the switch will be moved to starting position, and means for restoring the switch to stopping position when the pull on the conduit is released.
4.
