Application filed June 12,

My invention relates towaterfountains and more particularly to a device of that character for servicing automobiles and like vehicles at filling stations and constitutes 5 improvements over my co-pending application Serial Number 451,237, the principal object of my invention being to provide means for elevating a servicing fountain from alevel below the line of frost to a convenient position for operating-the'device.

It is a further object of this invention to embodysimple and effective means for sustaining the fountain at difierent elevations and to cushion the return of the device to lowered position. i

In accomplishing these and other objects of my invention I have provided improved details of structure the preferred form' of which is illustrated in the accompanying drawings, wherein:

Fig. 1 is a central vertical section of a servicing fountain embodying my invention, illustrating the elevating mechanism, parts being broken away to more clearly show the I construction of the device.

Fig. 2 is a fragmentary, perspective view of a hose support and locking member, and of a guide associated therewith.

Fig. 3is a cross section ofthe container and servicing mechanism on the line 3 -3 Fig. l.

- Referring more in detail to the drawings 1 designates a container, preferably constructed of metal andinserted-in an opening-2 at some convenient location on the filling station premises, the upper end of the container extending through a concrete floor 3. I I

Extended through an opening 4 in the icontainer wall and leading from a source of water supply is an inlet line 5 provided on the end projecting into the container with a valve 6 for controlling flow'of liquid into a flexible conduit 7, secured to the valve by a clamp 8.

, In order that the outer endof the hose, provided with the usual bib 9 for filling radiators and the like, may be readily moved from a position below freezing depth to a .imore accessible location, adjacent the ground 1930. Serial no. 460,698.

surface, I have provided a supporting and elevating mechanism generally designated 10. The elevating-apparatus includes a pair of parallel'shafts 11 and 12, connected at. their upper ends, and spaced sufliciently to be mounted astride .the wall of the container, the shaft 11 slidably engaging a longitudi-' nal, tubular guide 13 having outwardly directed'fianges 14 fixedto the outer wall of the container by welding or the like as in}, dicated at 15. I

Integralwith the inner shaft, relatively near the lower end thereof and projecting inwardly from the shaft is an apertured arm 16. A supporting bracket 17 in the form of a band is secured to the arm by a bolt 18 and surrounds the cylindrical barrel 19 of a jacl: 20. p

Externally threaded lower and

upper ends

21 and 22 of the cylindrical barrel are adapt ed to respectively receive a foot member 23 and a cap screw 24, a fitting25being threaded into a port 26 of the foot member to communicate the cylinder with a hose 27 leading from the jack through the open end of" the container so that the ad: may, thereby, be connected toa source of compressed air or the like for elevating a piston 28 reciprocably mounted in the barrel.

The piston 28 preferably includes a pair of spaced cups, 29 and 30 secured to the lower end ofanelevating rod 31- .by nuts 32. A concentric opening 33 in the cap screw 24 is adapted to slidably receive the rod 31 which terminates at'its upper end in a reduced shank 34, adapted to be received in an opening 35 adjacent theend of a supporting arm 36 maintained in fixed position on the end of the rod by a washer 37 and by a nut38 applied to the threaded end 39 of the shank 34. (lush ioning springs 40 and 41 arerespectively provided in'the bottom of the cylinder and on the rod 31 above the piston. V A relief port 42 in the cap screw 24 permits discharge of air compressed in the cylinder above the pump plunger on its upward stroke, and a series of ports 43 near the top of the cylinder relieves the pressurein the cylinder when the pump plunger has reached its upper limit of travel so that only suiiicient resistance n as will be offered the piston on its return or downward stroke to effect a smooth and slow return of the supporting arm.

The supporting arm includes an integral ring portion 44, substantially concentric in relation with thecylinder for receiving the conduit? ,apherical member 45 secured on the hose, adjacent the bib being adapted to rest on the arm when the hose is returned to 19 retracted position in the container by a weight 46 suspended on the hose by: apull'ey'47;

Threaded on the outer end of the supporting arm is a head 48 having anenla-rgedsocket 49 for receiving a bearingballbO. yieldingly urged outwardly against the'inbent edge 51. of the socket byan expansion spring- 521 seatedinzthe. supporting, arm, adjacent the en, larged socket 49. j

A. channel. member 53 preferably Ui-shaped ina-crossasection. having outwardly directed flangesfi l, is fixedto the inner face of the container Wallb- Welding orthe liketo serveas a guide, for tiiehead 48 in itsreciprocate ing travel, in, the container, and sockets 55 may be; provided in the base ofthe channel: for seating the ball 50 urged into'saidsocketf under-tension of the spring52so thatthe sup porting'arm and the discharge end of the liose will be sustained'in: elevated relationin; the container.

To facilitate manual elevation ofthe supporting arm when air pressure for the 'j ack is not available I have pivotaljly attached ahandle 56 to'the upper end of the shaft 12 by bolt 57,. the handle normally remaining; in! lowered position adjacent the shaft Wit-Iran apparatus constructed assembledfas described and with the supportingarm inilowered position-in the container, compressed, air may be admitted to. the jack throughthe port 26 to forcethe-piston upwardly,.thereby elevating the supportingarni, andthe discharge endof the hosetoan acces-' sible position near the'surface of the ground.

Upon reaching its upper limit of travel the bearing, ball in the head of the supporting. arm engages the upper socket, in the guide channel, thus preventing return ofthe supporting 1 armintothe container until asufficient amount of pressureis applied on the anntordisengage the ball from the socket against-t-hetension of the spring.

Duringthe, warm seasons of'the year the discharge: bib: may be maintained in entirely elevated position, however, when; there is danger 'of light frost the lower socket 555 maintainsthe-supporting arm sufficiently far be low the surface of the ground to' admit the bibinto thecontainer so that the container may be covered, While this position of the" support isnotlasaccessible as the entirely elevated-position, it'eliminates the necessity of elevating the supporteach time a car is to be; serviced As soon asthe danger-of heavy frost approaches the supporting arm is moved to its lower limit of travel when not in use to prevent freezing of the water in the conduit 7.

If, for any reason, it is desirable to manually elevate the bib the operator pulls up- 7 Wardly on the handle 54 until the bearing ball is seated in the upper socket With the structure heretofore described the bib may be readily elevated either manually or automatically and While other means 7 such as along conical spring may be substituted for elevating the bib, the present mechanism-has proven most satisfactory.
