Cox, Los Angeles, Calif., assìgnor'of one-half to Daniel W. Cox, Los Angeles, Calif. Application April l, 1936, ScrialNo. 72,096 14 Claims. This invention relates to dispensers for ñuids; such, for example, as are used in and about serv ice stations for automotive vehicles. As shown and herein described, it is used primarily for dis CTl pensing water and air. It is to be understood, however, that it is adaptable for dispensing other` fluids and for use in places other than service stations. on or about March 4, 1935, 1 med application' , l0 N0. 9,189 for a patent covering an apparatus for the same general purpose. Subsequently, I made some changes in that >apparatus which changes are embodied in the present invention. As re spects the subject matter that is common to these l5 applications, the present case may be considered a continuation in part of the said earlier appli cation, although the latter has now become aban-, doned. - (Cl. 299-77) ' view on the line 2_2 of Fig. l; Fig. 3 is a similar vview as on lthe line 3_3 of Fig. 1 but showing a modified structure and illustrating a means for maintaining the temperature within the well above the freezingv point; Fig, 4 is a plan view 5 showing the upper face of the cover, the dispens ing valves being removed;- Fig. 5 is a transverse or horizontaly section taken on the line 5_5 of Fig. l; Fig. 6 is a similar view on the line 6_5 of Fig. 3; Fig. 7 is a side elevation of a modiñed 10 structure embodying my invention; Fig. 8 is an isometric view of the removable part of the cover; Fig. 9 is a fragmentary sectional View taken dia metrically through one of the sheaves; Fig. 10 'is a sectional View taken centrally through yone of l5 the balls for supporting the dispensing pipes; and Fig. 11 ls a sectional view taken longitudinally through the outer end of one of the dispensing , The principal objects of the invention are the pipes. 20 provision of a dispensing apparatus which shall Taking up a description of the invention by 20' be economical in manufacture and reliable in-use; reference to the drawings, omitting for the pres'- Y which shall not be subjected to excessive wear . ent the modification shown in Fig. ‘7, 2B is a. casing ‘ and will be durable; which will not permit abra or well which is usually embedded in the ground, sion of the dispensing hose against the guides or standing vertically therein with the ground level 25 the kinkingv of the hose; which is capable -of ready at 2 l.

In its simpler form, as shown in Figs. 1 and 5, it is made up of two channel-shaped, section into which the hose is retracted after use; 35 which provides a closure for the upper end of the side members, a and b, each of which has out- 35 . v well or guide with anti-friction rollers associated wardly-turned ñanges 2|a on its longitudinal therewith for guiding the hose pipes as they are v edges. When these two members are assembled, moved in and out of the well; which maintains as- in Fig. 5, they provide a long, rectangular the service pipes for the hose underground to chamber which is substantially closed at one .end-A 40 prevent freezing of the ñuid and provides means and open at the other en_d.

The casings, therefore,'form not only guides for the result in rupture or leakage of the pipe. vTo pre vent such excessive movement of the sheave, I ' sheaves b_ut retaining walls for holding the surattach to the part 3l of the cover _a stop mem~ rounding earth.

This movement from place to place. In the service stop may be, and> preferably is, integral with the' stations referred. to, it is a common practice to member 34, hereinbefore'described. As shown in - position containers for and dispensers of various Fig. 2, the stop is centrally positioned over the kinds or grades of oil on a sort of carriage which partition and projects far enough on both sides-to can be moved about.

Thereafter, the pipe can be » uncoupled and removed. . Figs. Band 6 show a modified form of the ap paratus. In them, the reference characters here tofore used will be employed as far as applicable. 40 The casing membersa" and b'are the same as the corresponding members a and b except that the parts forming the bottom of the casing are somewhat extended _to abut at the center. Be-- balls 29. The pipes are kept taut by the sheaves, outlined‘at dii. In fact, the structure of the cas ings and the dispensing elements are the saine 35 as have been described except that they are mounted within the pedestals instead of being beneath the ground. Therefore, further illustra tion and description are deemed unnecessary. The service supply pipes 58 are above ground 40 and are, of course, long enough to permit the carriage to be moved about as may be required when in use. ' When the apparatus is not _in use, as when the station is closed for the night, the cover 3i 45 tically from top to bottom of the casing, thereby or 3|a is moved and the outer ends of the dis separating the sheave chambers and providing. pensing pipes with their cocks 28 are dropped a third chamber 46.

The interposition of the space 55 46 between the sheave chambers'necessitates a the bottoms of the casing and the pipes taking a shape such as is indicated in dotted lines in 50 Fig. 1.
