UNITED STATES PATENT OFFICE.

JOHN B. DAVIS, OF SPRINGFIELD, MASSACHUSETTS, ASSIGNOR TO GILBERT & BARKER MANUFACTURING COMPANY. OF WEST SPRINGFIELD. MASSACHUSETTS. A COR- PORATION OF MASSACHUSETTS.

LIQUID-DISPENSING APPARATUS.

Application filed April 13, 1923.

To whom it may concern in it known that 1, JOHN B. Unis, a 'li ZLH of the United States, resid ng at Tfln'ingtieid, in the county of llanipd n and State of Massachusetts. have invented new and useful Improvements in Liquid l lispens ing .;\pparatus, of which the following i a specificatione- This invention relates to liquid dispensing apparatus, such for example as is used for dispein-iing gasoline or other oils. and is more particularly concerned with improvements in the means for receiving the drip from the dispensing faucet and conducting the same back to the supply reservoir.

One example of the general type of apparatus with which this invention is; eoncerned will be found in United States Letters Patent No. 1,305,289, granted June 3, 1915) on an invention of Charles V. Kincaid. In general, such apparatus con'iprises a reservoir, in which is mounted a n'ieasuring or dispensing pump to draw oil from the reservoir and deliver it through a dispensing faucet, and a movable drip receiving and conducting tube normally held by \'ieldahle means beneath the faucet.

Outfits of this character arev oftentimes supplied without charge to the retai er for use *ith a certain brand of oil and the tilling opening of the reservoir may he loci-ml or sealel to prevent the retailer from using the 01 with .another brand of oil l lo ever, it; is possible to swing the drip tube away t'rtin he dispensing fainr Jillttfll a hose to this tube and thereby illl the tescP voir with another brand of oil in an unintended manner. This invention is con ccrned with the provision of means to prevent, such misuse of the apparatus.

The invention has for its broad object to provide means for closing ofl' ('onnnunicat ion between the drip tube and reservoir whenever the drip tube is moved away from, or out of drip receiving relation with, the dis pensing faucet.

Other objects and advantages will. appear in the following description and in the illus trative embodiment of the invention in the accompanying drawings in which Fig. 1 is a fragmentary elevational view. with parts in section, of a liquid dispensino apparatus embodying the invention; and

Serial No. 631.843.

Figs. and I) are sectional plan views taken on the lines and l fl, respc tiv ly, of Fig. 1.

.l ieferring to thesidrawings; there has been shown, by way of illustrative example. one type of liquid dispensing apparatus with which the invention is adapted to he us d. The in ention, however, is largely. independent of the constructional features of the dispensing apparatus and many other sui ahie types will readily occur to tho e l ll il in the art. hat type'ilhistrated herein is sul'istantxially like that disclosed in the above named patent.

The apparatus includes a tank or supply reservoir 5- to receive the oil and a nieasuu mg or dis 'iensing pump mounted thereon. The pump includes a cylinder ti which is. disposed within reservoir 5 and Hu'iported by a cap plate 7 secured to the top wall of the reservoir. The piston rod of the pump is shown at and is attached ti. a rack bar 9 which ma be i'eciproeated vertically by means of a crank handle 10 in the usual and well known manner. The upper frame, 11 of the pump is attached in upright relation to plate 7 and on this frame may be mounted one or more quantity stops 12, adapted to eooperate with an abutment 13 on the i bar 9. all in the usual and known 1 The intake pipe for the pump is sh 14 and the discharge pipe at 1.3. ln: extending nnwardly from p guided in t ie 11, and ha, end turned f grin angles and s. a dispensing taut-ct it having l dire ted noZAle 1T.

'lhe drip tube laterally i'iti sct an"; .ertically di pow tion l one of whi-rh is adapted to the nozzle 17 to receive the. drip. The other portion is mounted to turn in a. pipe 15 which is tapped into and depends from plate 7. Pipe 19 is capped at its lower end, as shown at 231'), and is provided with a lon gzitudinal slot 21. Tube 18, at its lower end. is provided with a similar slot 22 Fig. 3) and the slots and 252 are adapted to r411;- ister when tube 18 occupies the'position in dieated by full lines in Fig. 1. hen moved out of such position,toward that indicated by dotted lines in Fig. .1, the slots and :22 are moved out of registration discharge pipe 15.

and, since. cap 20 closes the lower end of tube 18, no liquid can then be supplied to the reservoir 5 through the drip tube.

Tube 18 preferably has a conical ring 23 which rests upon a similar ring 24 on plate 7, the purpose of this arrangement being to prevent water from entering the reservoir around tube 18, where it passes through plate 5.

The nozzle 17 may likewise have a conical li,ood 25 to overlie the inlet end of tube position just described, such as a torsion spring 28, which encompasses the tube 18 and has one end 29 received in a recess provided in a circumferential flange 30 fixed on the tube. The other end 31 of 1 spring 28 is extended tangentially (Fig. 2)

and strikes against one inner wall of a two part casing 33. The parts of casing 33' are drawn together by a bolt 34 and clamped to This casing 33 encompasses spring 28 and forms a guide for tube 18 in its swinging movement. The upper wall of casing 33 overlies flange 30 and prevents withdrawal of tube 18 from pipe 19.

The operation of the apparatus will read ily appear from the foregoing description.

The invention has been disclosed herein, in an embodiment at present preferred, for illustrative purposes but the scope of the invention is defined by the appended claims rather than by the foregoing description.

I claim: I

1. The combination with a reservoir, of means through which liquid may be with drawn therefrom including a delivery spout, a drip conductor including an inlet portion movable into and out of .drip receiving relation with said spout and an outlet portion opening into said reservoir, and means operable by movement of said conductor out of drip receiving relation with the spout to cut off communication between said inlet and outlet.

2. The combination with a reservoir, of means for delivering liquid therefrom including a dispensing faucet, conducting means to convey the drip from said faucet back-to the reservoir including an inlet portion movable into and out of drip receiving relation with the faucet and an outlet opening into said reservoir, means to yieldingly hold the inlet portion in drip receiving relation with said faucet, and valve means operable by movement of said portion out of drip receiving relation with the faucet to close off communication between said portion and said outlet.

3. The combination with a reservoir, of means for delivering liquid therefrom including a faucet, a drip conductor mounted to move toward and away from said faucet, means for yieldingly holding the conductor in position to receive the drip from said faucet, said conductor communicating with said reservoir when thus positioned, and means operable by movement of the conductor away from the faucet to cut off the communication between the conductor and said reservoir.

4. The combination with a tank, of means for delivering liquid therefrom including a faucet, a drip conductor mounted to swing toward and away from the faucet, means for normally holding the inlet'end .of said conductor beneath the faucet, means on the tank depending into the interior thereof and forming a cylindrical socket in which the outlet end of said conductor is mounted for turnin movement, and openings provided in said means and conductor adapted to register when the conductor is disposed in drip receiving position. y p

In testimony whereof I have atlixed my signature. I

JOHN B. DAVIS.
