OF" ONE- LIQUID-DISPENSING MEANS.

Original .No. 1,599,105, dated September 7, 1926, Serial No 756,665; filed' necemher 15, 924. Application for reissue filed'November 21, 1927. SeriaLNo. 234,880. l y I This invention relates'to improvements in liquid dispensing means.

In the accompanying drawings which serve for illustrating the invention:

Fig. l is a View in side elevation otthe improved mechanism;

Fig.2 is a detail View of a. joint for connecting the mechanism to a source of liquid supply;

Fig. 3 is a detailv sectional view of a telescopic joint for extending the mechanism; Fig. 4 is a detail sectional view-taken on line 4;-4 of Fig. 2;

Fig. 5 is a cleta1l sectional View taken on line 55 of Fig. 4; i

Figs. 6 7 are detail views of a holder for the'liquid dispensing device when not in use.

The invention consists, as here shown, in

a telescopically arranged, extendible tube in cluding' a section of flexible hose, adapted to be attached at one end to a source of liquid supply, as the discharge outlet of a liquid dispensing pump, and to be' extended and connected at its opposite end to-a' receptacle for receiving liquid dispensed. through the tube, as the'gasolin'e tank ot'a motor' vehicle,

the extendible t-ube being a substitute for the common type of hose used'onliquid dis' v I I for suitable packingmaterial 6 which is pensing pumps.

tubes connected to the sourceof liquid sup' ply by a variably adjustable joint which compensates for the variousturns and angular positions of thejtubeiwhich' are necessary positions of the machines relative to the pump.

The straight line extension of the metallic tube serves the'double purpose of overcom-' ing flexingand the torsional stresses of the" hom. which result in ordinary liquid dispensing'hose incident to draining'the. liquid therefrom, and of insuring complete'draining' of the tube and full measure of liquid to thecustomenf i In ordinary liquid dispensing" hose, as is;

Theobjec-ts attained in the invention conj sist in a metallic tube comprising a plural-f ity of telescopically arranged, .extendible hose. The necessity of holding the hose in raised position also results frequently in failure to effect" complete drainage of the hose and, accordingly, in delivering'short measure of liquid .to the customer.-

Referring to the accompanying drawings, the numeral 1 designates a di sch'argeftube' on a liquid dispensing pumpor tank (not shown). The tubel is exteriorly threaded at its lower end to receive an internallythreaded coupling sleeve 2 by which there'is connected to the tube'l, an intermediate-tube 3. The latter is forme d with an external annular shoulder i which'i's'engaged byan' annular internal shoulder 5 on the coupling sleeve 2 that is externally threaded-at its lower end to receive a nut-6. V The lower Wall of the coupling sleeve '2 isb'eveled inwardly to form ane'nlarged cavity Within the'niit,

pressed against the'outer' surface of-the tube 3 for efi'ectiiig' a liquid fight connection be-' tween the tubes 1 and 3. (See Figures'1,2" a'nd4.) l i At its'oute'ren d the tube 3 is exteriorly threaded for connecting itto. a threaded boss 7 on a cylindricalcasting 8 intowhich there is preferablydrilledfrom'one end, a hole 9 that communicates with the outer endpf tube 3 through the boss 7: The innerfend of the casting s is internally threaded around the external surface of the tube 10, to effect a liquid ti 'ht connection between the latter I and the T. (See Figures 1 and 4.)

Threaded into the side outlet of the T 12 is one right-angled end 17 of a tubular casting 18 which is'in substantial parallelism with the casting 8. The casting 18 is formed, preferably in radial alinement with the boss 7, with a right-angled bend 19 'thatis tapped to receivevtheinner end of a tube 20. The outer end of this-tube 20 telescopes into a tube 21, the inner wall of which is formed with an annular enlargement 22 whichis adapted to be engaged by an annular shoulder 23 formed on the outer end of the tube Ito prevent the tube 21 from being pulled ofilf (See Fig-- ures 1 and 3.) c

Surrounding the inner end of the tube 21 is I an exteriorly threaded sleeve 24v the inner' 20 edgeotwhich is chamferedJ 1 Between this sleeve 24 and a gland 25 beyond it, is suitable packing 26 which is adapted to, be pressed against the tube 20- by the gland -When-a sleeve nut 27 is screwed onto'the sleeve. (See Figure 3.)' A :liquid ti htconnection is thus formed betweenflthe te escopie tubes 20 and 21 without interfering with-the axial move ment of the'tube 21 over thetube 20. I

I The tube 21 is telescopically connected in .a

si nilar manner to 'a. tube 28,- and the latter in a like manner to a tube 29. WSecuredin a liquid tight mann er to the outer end of the tube29 is a short section of flexible hose 30 to the outer end of which a wcured; (See Figur'e .1.) v e Formed on the close end of/the casting 8,

is a Wide-flange 32;, Axially projecting ,be-

yond the latter from the castingS is a cylindrical extension33 terminating in a squared -4o-=, reduced portion34, (See Figures 4 and 5.) 4

The extension 33 ends be 0nd its; squared portion in a reduced roun end 35 which is externally threaded to receive a nut 36.' (See- F igure 4.) 'f

-. Free to revolve upon theaxial projection 33; is'am'etal disc'j37 which is formed at its inner end with an. extension that is turned to providega part,38 parallel with its disc part,

'forat-tachmentby suitable fastening elements 50, such'as screws 39, to the end surface, of the bend 19 of the casting 18. ,Between the disc 37 and the flange 32 on the casting 8, is a friction disc {10 and between disc 37 and a disc 42 I applied tothe squaredportion 34 of the extension 330i the cast-ingis a friction disc 41.

(See Figure 4.)

I tension 33 is a washer 43 which is adapted to be ,engaged by the-nut 36 to press the disc e0 42,with=the desired degree of tension, against the remai-ning discs and the flange 32 onthe casting to control the frictional resistance which the fiber discs-4O and 41 oflfer to the rotation of the metal disc 37, onthe casting extension 33.

nozzle 31' isse- Referring to Figure 1, there is secured to the T 12, opposite its side outlet, an arm 44 which carries on its outer end a counterweight 45 for the purpose of balancing the telescopic delivery tube unit. However, this counterweight may be dispensed with. if desired;

Pivotally secured by a screw 16 to the middle portion of the casting 18, is an arm 47 to the outer end of which is secured a springfork clamping member 48 which is adapted to be applied to the tube 29 below the sleeve nut 27 on its inner end, to hold the telescopic tubes in their nested positions. (See Figures 1, 4, 6 and 7.)

'The tube 3 is free to revolve Within the coupling 2, to enable thedevice to be turned about the axis of the pump outlet tube 1. With the T 12 free to be revolved about the tube 10, and "the. metal disc 37 free to beturned around the c'astin telescopictube unit may e raised and lowerjed when desired. This telescopic tube unit,

extension 33, the" being balanced by the counterweight 45, may

'be easily raised and lowered by a filling Sta-- tion attendant, and held in an adjusted position by the frictional resistance voffered to therotation of the Inetal disc 37 by the'fiber discs 40 and 41'. Furth ermore,the telescopic umt maybe easily extended or contracted to bring the nozzle directly over the opening in an-automobile tank, .into which the full amount; of liq'ui d fuel drawn from the pump will, flow, since there are no in the device totrap it. v I

'-Wh1le the extendible tubes, ashere shown,

pockets or loops are provided with suitable packing at the joints,"it will be seen that leakage at the Joints ill not occur 'in the normal use of the tubes as liquid dispensing means of the character claimed, as 'the flow of the liquid is from. the Smaller to larger tubes, the outer' ends of the sections at the'joints being extended inverse direction to the movement ofthe-lliquid, and there'being no back pressure on the liquid, leakage at the joints will about, one end of the horizontal tubular I structure, and apivotal braking connection Mounted on the end 35 of the cast ng ex- 2 .Liquid dispensing means comprising a: pump outlet, a horizontal casting open at one end, means for connecting the casting pivotally to sa idoutlet, a tubular structure connected to the open end of said casting for rotation about its longitudinal axis, a disc member rotatably secured 'to the other end of said casting and having an extension fixed to the tubular structure, a friction disc on each side of the disc member, and means on the casting for pressing the friction discs against the disc member for the purpose specified, said tubular structure-having universal manually controllable movement from its connection with the pump outlet.
