4 Claims.

The present invention relates to hose wells, and particularly to a well and hose retrieving mechanism of the kind used in automobile service stations to house and protect air and water service hoses.-

Hose wells of the kind referred to generally comprise elongated casings adapted to be sunk below the surface of the ground to provide subsurface compartments for the reception of hoses. The delivery ends of th hoses project through a cap on the upper end of the casing and any desired length of the hose may be withdrawn for use. Weights Within the well serve to retrieve the withdrawn portions of the hoses when they are released.

It is to the hose well cap and the retrieving mechanism that the present invention is'particularly directed, and it'is the object of th invention to provide a hose well in which the cap and retrieving mechanism insure smooth, positive operation upon withdrawal and retrieving of the hoses.

Further objects of the invention are to provide a compact and convenient arrangement of antifriction bearings with which the hose engages upon being withdrawn; to provide a cap in which leakage of water into thewell is minimized; to provide means for insuring against breaking and damaging of the hose; and to provide means for conveniently locking the hose in the well beneath the cap when the hoses are not in service.

Further objects and advantagesof the invention will be made apparent in the following specification, wherein one form of the invention is described in detail by reference to the accompanying drawing.

' i In the drawing Fig. 1 is a central vertical section of a hose well embodying the present invention;

Fig. 2 is a plan view of the hose well;

Fig. 3' is a view similar to Fig. 2 witha portion of th cap of the well removed; and:

Fig. 4 is a similar view with a second portion of the cap removed.

As illustrated in Fig. 1 of the drawing, the well casing HJ is of cylindrical form with its lower end closed by an end member I l. The cylindrical form of casing is preferred because a conventional post-hole digger may be used in preparing a hole suitable for its reception, and because of its relatively high resistance against compression forces in case the earth about it settles and tends to press inwardly on its walls.

The casing I0 is divided by an interna wall [21 to form twoserni-cylindrical chambers, s indicated at I3 and I4 in Fig. 3. This wall is illustrated as formed of a single sheet of material but may be made of spaced sheets to provide a narrow compartment for the reception of an electric heating element of conventional design for use in localities where there is danger of freezing temperatures damaging the Water hose in the well.

Each of the chambers 13 and I4 encloses one of a pair of valves l5 supported. by fittings l6 (see Fig. 4) which extend through the wall of the casing ID for connection with conduits not shown which lead to sources of supply of compressedair and water. Depending from each of the valves l5,is a flexible hose I! which passes under a sheave l8xjournaled on a pin l9 which extends through a recess in a Weight 29. The delivery ends of the hoses ll extend through suitable openings in the cap of the cylinder and are provided with enlarged fittings 2| to prevent them from being withdrawn through the openings in the cylinder cap. When it is desired to use either of the hoses, the end which extends through the cap is withdrawn and as the hose passes over the sheave l8 it raises the weight 20 in the casing.

The downward gravitational movement of the weight 20 serves to retract the hoses into the casing when the ends are released.

As the hoses are connected with the valves IS in a manner to cause them to extend downwardly therefrom, there is a tendency upon withdrawing them from the casing too far to bend them too abruptly and cause weakening and breakage at their point of juncture with the valves. In order to prevent damaging the hoses in this manner, the distance that they may be Withdrawn from the casing is limited by a stop member in the form of a rod 22 which extends upwardly from the upper end of each of the weights 2!! so that upon upward movement of either of the weights, its rod 22 will strike against the under side of the cylinder cap and prevent further withdrawal of the hose before the inner end thereof has been caused to kink at its juncture with the valve l5.

The top closure of thecas'ing ID comprises an annular collar 25 fitting the upper end of the cylindrical casing, preferably internally as shown,

and secured thereto by any suitable means such.

for example, as'cap screws 26 threaded through the collar and projecting through registering openings in the casing wall. A closure capsupported by the collar 25 comprises

separablesections

21, 28, and 29. The section 21 which is the smallest of the three cap sections, is permanently securedto the collar 25 and may, as illustrated,

be formed integrally therewith. The section 29 is also secured to the collar but is adapted to be removed to permit access to the valves 15 for the purpose of making repairs or replacements and. to permit convenient removal of the weights 2!] when necessary. This section is secured to the cap by some semi-permanent means, such, for example, as screws 38 which project downwardly through th cap and enter lugs 3| formed integrally with and projecting inwardly from the collar 25. The screws 36 may project through the lugs 3i and have nuts 32 threaded to their lower ends and accessible from th interior ofv I g a roof or table 4| supported directly above the cap of the well on an upright post 42, the lower th casing only in order to prevent their un authorized removal. The central section 28 is only temporarily se to each other and the consequent difficulty in making repairs.

The entire top surface of the cap which is formed by the

separate sections

21, 28, and 29 is formed with suflicient curve or slope, as indicated in Fig. 1, so that moisture will tend to drain away from the openings through which the hoses extend instead of draining toward said openings and eventually flowing into the casing. As it is undesirable that any appreciable quantity of moisture be allowed to enter the casing, further precaution is taken against rain or snow falling directly on top of the casing by the provision of end of which is received in a socket 43 which is cured to the collar 25 by means presently to be described sothat it may be readily removed when it is desired to store the hoses entirely within the-- well and lock them in an inaccessible position, as maybe desired-after business hours or when the service station is closed. To facilitate withdrawal of the hoses l1, anti-friction rollers are provided to clrcumscribe openings in the cap through which the hoses are withdrawn. One side of each of ithe openings, which are'generally rectangular inshape, is formed on the permanent cap section 21, while the other three sides of the openings are formed in the removable cap section 28, so that upon removal of this section, th ends of the hoses may be removed from the openings and let down into the well.

The anti-friction rollers on the side of the openings formedion section 2'! are shown at 33 v rated for the reception of a cap screw 39 passing upwardly through the plate and threaded into a suitable opening in the removable section 28. This cap screw thus supports the plate 38 with respect to the section 28. The plate 38 also has an outwardly projecting tongue, 39A which underlies the inner edge of the permanent cap section 21..

The top of the removable section 28 and the top of the section 29 are provided with upwardly extending lugs 40 which have registering perforations through which a pin, padlock, or other securing means may be inserted. 'When the removable section 28 is in place, the tongue 39A underlying the section 21 and the pin or padlock through the perforated lugs serve to lock the section 28 against removal. This prevents unauthorized tampering when the hoses are in service and whenthe hoses are out of service, that is to say, when the section 28 has been removed and the delivery ends of the hoses let dowrrinto the well, the section;28 maybe replaced and. locked to prevent access to the hoses.

The plate 38 which supports the bearing lugs 31,-for therollerstii maybe removed by removal of the single cap screw-.39 so that. upon wear or breakage of any of these rollers or their-bearings, a new set or six rollers maybe installed in a single Op ation- T i is as d n e b a of t gloss e i iriv t e-mllsnsae theirsbearings formed integrally with the cap section 29. This socket maybe internally threaded and a thread provided on the lower end of the post 42, but it is preferable that a slight taper connection be made to facilitate removal of the table 4| and post. 42 when it is desired to remove the cap section 29. .This'table 4| serves not only to protect the well from moisture but may be used to support a cash drawer or to support receptacles for cloths or tools used in the ordinary servicing of an automobile.

While the present invention has been more or less specifically described for purposes of illustration, it is to be understood that various changes may be resorted-t0 in the construction and arrangement of its several parts within the scope of the appended claims. i i Having thus described'my invention, what I claim and desire to secure by Letters Patent is:
