'CONCEALED HOSE DISPENSING APPARATUS I Filed NOV. 26, 1938 2 Sheets-Sheet 2 Patented Sept. 9, 1941 Harvey E. Marvel, Fort Wayne, Ind., assignor'to S. F. Bowser & Company, Incorporated, Fort Wayne, Ind., a corporation of Indiana Application November 26, 1938', Serial No. 242,553

6 Claims.

This invention relates to liquid dispensing apparatus of the concealed-hose type in which the greater portion of the dispensing hose is con tained within the housing of the apparatus on a hose reel. a

'While the broad idea of storing the hose in this manner is old, as shown by Carroll Patent Number 2,113,676, issued April 12, 1938, certain difficulties have been encountered in attempting to fit a hose reel in a housing of the -'usual size.

In attempting to do this, it has been found necessary to resort to the use of a reel of small diameter having the hose wound thereon in-laterally adjacent courses or convolutions, and this brought with it the problems of guiding the hose on to the reel so that it would wind properly upon the reel without jamming.

Some difliculty was also encountered in securing a free operation of the reel itself, since the combined resistance of the retrieving spring and rotary seal constituted a considerable load.

Accordingly, it is an object of the invention to provide, in a dispensing apparatus, a free running and sure winding hose reel.

Another object of the invention is to provide a hose reel adapted to store the hose in laterally adjacent courses together with means for guiding the hose into proper position thereon.

Yet another object of the invention is to prostudy of the following specification and the accompanying drawings in which:

Figure 1 is a side elevation of a dispensing pump showing the hose in retrieved position Figure 2 is an end elevation of the apparatus of Figure 1. j

Figure 3 is a vertical section of the hose reel,

rotary seal and retrieving spring.

Figure 4 is a vertical section showing the slid ing. connection between the air release and the dispensing line.

Figure 5 is a side elevation of the lower portion of thedispensing apparatus with the housing removed.

Figure 6 is a vertical end elevation of the mechanism of Figure 5.

Figure 7 is a section taken on the line 1-1 of Figure 2 showing the arrangement of the rollers.

' Numeral II in Figure 1 represents, generally,

a dispensing apparatus which is provided with a hose hook l3 which is adapted to supporting noz zle l5, which is attached to the dispensing hose The lower portion of the apparatus is provided with a bracket I9 which supports a primary guiding roll 2| at an angle of about 45 degrees from the vertical.

As shown in Figure 5, the apparatus ll comprises a base member 23 to .which is affixed a per side of bracket 21. A motor 35 and a pump 3'! are mounted upon the air release 33 and are connected by a belt 39.

An openin 4! (Figure 4) is provided in the upper wall of the air release, and is internally threaded to receive a threaded nipple 43; Before the nipple is screwed into the opening, a piece of pipe 45, which is of sufiicient length to reach to a point adjacent to the bottom of the'air' release is welded to the lower end 47 of the nipple. The nipple iscounterbored at 49 to receive the lower end of a pipe 5|, which forms a portion 01 a dispensing line which is connected with the meter:

nectedby piping to the meter, so that unless some provision is made in one or the other of the pipe lines to take care of inaccuracies of manufacture and assembly, one or more of the units would be unduly strained and this would lead to trouble. In view of the fact'tlzgat it is sometimes necessary to replacethe separator, the

slip connection, which is a separable one, is 10- cated at the separator so that replacement of the separator may be made without disturbing the hose reel mechanism. On the other hand, since the hose reel is disposed down stmf the separator and meter, it may be replaced without disturbing either of these elements.

The pipe 5| is connected to'the' meter 3i through a combined check and relief valve 8|.

This valve is preferably of the composition type and occupies a horizontal position. It is adapted to open with the flow or liquid from the air release to the meter against the pressure of a light the connection I 35 increases, and after the anguspring which is adapted to urge the valve to-- ward a closed position so that it will seat readily when the pump is shut down. The valve contains a small relief valve (not shown) which is adapted to open with the flow of liquid from the meter to the air release, which may occur when .the pressure in the system above the check valve increases .due'to rising temperatures.

- From the meter, the liquid being pumped passesthrough a pipe 63 to the sight glasses 65 (Figure 1) and then downwardly through a pipe .1 to the inletconduit I which leads to the hosereel. Thisconduitformsapartofasupporting member II, which is flxed to the columns 25 by means or supporting lugs I3 on conduit i9 and similar lugs on IS.

The member II also comprises a vertical arm I1 which is attached to the cross member 21. The conduit "is formed with a tapered opening I! which is adapted to receive a hollow axle member ll, which is adapted to support the hose reel. Two concentric flanges It and 85 are formed about the axle 8| and the outer one of these serves to anchor one end of the retrieving spring .1 which is flxed at its otherend to an .inwardly directed flange 88 on the reel. The

other flange ll serves to limit the inward move- 'ment of the reel on said shaft.

A hardened ringsl abuts the flange us, while .5.

' similar ring 83 abuts the hub 95 of the hose reel.

A perforated ring '1 lies between rings SI and 93 and carries roller bearings II. These elements The inner portion of the hub adjacent the lar distance of 360 degrees is covered, the two grooves I31 and I39 areof equal depth and are defined by a. rib or flange Ill. This rib is interrupted at a point less than 360 degrees from the connection I35 so that the hose may cross from groove I31 into groove I38 after about one revolution has been made, and groove III will take up the hose remaining to be retrieved.

' As shown in Figure 6, the hose reel is disposed at oneside of a plane running centrally through the dispensing unit in a transverse direction. Since the hose should preferably issue on the line of intersection of this plane and the side of the pump, it is necessary that the reel axle be axis is inclined from a perpendicular to said central plane and so as to direct the hose toward the desired outlet point.

Aplanar element M5 is attached to columns 25 by means of screw fastenings I 41 and supports the bracket I9 heretofore referred to.

The bracket I9 is provided with a pair of rolls I" which are mounted upon axles I, one on each side of a plane passing centrally and edgewise through the dispensing unit. The right handroll I43 (Figure 6) is disposed at a greater distance from the central plane than is the left hand roll, so that the hose II will be deflected toward the right of the plane'as it enters the unit, and thus is biased. toward the hose reel. The rolls I" are inclined so that their respective axes extend at about3'7 degrees upwardly from the horizontal, the object of this being to maintain the axes of the rolls at substantially 90 dogrees to the direction taken by the axis of the axle ll is provided with an annular recess Ill,

which is counterbored at Ill to receive one part m of the thrust bearing, which is formed of stainless steel or bronzeand which is provided with a radial, flange. Said flange serves to compress a "Corpren'e" or other packing ring llll against the axle and the walls of the counter-bore.

A carbon ring III forms the other part of. the

hose so as to eliminate, as far as. possible, any friction between the metal roll and rubber hose.

The bracket I9 carries axles 'I5I upon which are rotatably mounted the rolls 2| which are of large diameter. Applicant prefers to' use rolls of at least three inches diameter where a synthetic, lined hose of about 1 outside diameter is used although this roll dimension is not the thrust bearing and is disposed on" the axle ad- 'Jacentthe element I". A packing ring III, of -Corprene or other suitable material, having a radial and an axial flange is disposed on the axle 'adiacent thecarbon ring. Ametal ring III surrounds the axial flange, while a cupped ring III encloses the radial flange. The ring Ill serves as seat for spring I". F

. A retaining element in is pinned to tneexie ll by means ofa-pin III and isprovided with a seat I23 which is adapted to .receive one end of the spring II! of the rotary seal. A flange I21 on the retaining element'lll abuts the face I28 on thehosereel and serves to retain it against axialmotionontheshaft.

A chamber! is formed in the hose reel at the side opposite spring :1 and a c n is tached to the :hose reel as'by cap screws I" so as toi'orm a discharge chamber into which conu ites wmemptr by way of the hollow axle u.

.Chamber III isconnectedbya channel I to vent sharply kinking the hose as it is withdrawn from the housing. Kinking leads not only to undue wear-Lon. the hose but also tends to cause and are' inclined upwardly and to the right as breakage of the ground wires which are usually embedded in the hose and which connect the fittings on each end of the hose.

The axles oi these rolls. are disposed at an angle of about 45 degrees from the horizontal tially. perpendicular to the axis of the hose.

The reel and sets of rolls 2| and m are so that a plane eontaining the center lines of the sets will also contain the inner flange I.

rolls are disposed above and below rolls II and serve merely to prevent thefhose from coming in contact withsharp cornersor edges ofthehoiiising. L

Thebearingbracket iealsosupports horizontal I ,axles III upon which are mounted rolls Ill.

of groove I31 prevents the hose from passing provision of the slidable air release discharge Operation In operating this device, the station attendant will first remove the hose nozzle I from the hose hook I3 and carry it to the tank which is to be filled. If more hose'than that which extends between the-rollers 2I and the nozzle is required, the operator will simply pull on the hose from the position which he occupies and additional hose will be supplied by the unreeling of the hose reel and the paying out of hose through therollers I49, 2| and I53.

After dispensing is complete,-it is necessary merely to relax tension on the hose and the retrleving-spring 81 which was energized during the withdrawal of the hose will rotate the reel in a direction to retrieve the hose. The rolls 2| and I43 are so directed that they tend to urge the hose into the groove formed by. the flanges III and the outer flange. However, the depth' over at the start of rewinding; and as the groove I31 diminishes in depth, the flange I'll increases in height, so that there is always enough of a wall to prevent the hose from passing over toward the outer flange. However, as soon as the interruption in the flange is reached, as shown in Figure 6, the hose will cross over and will wind up in the second course; I It is quite obvious that the tendency of the rollers to urge the hose toward the outerflange must be limited to prevent the hose from leaving the groove which is provided to receive the first course. As the hose is wound up on the reel it will first occupy the groove I31 until a little more than one revolution has. been completed, whereupon the hose will cross over into the groove I39 where the remainder of it will be taken up. The rollers 2| and I43 are so disposed as to tend to guide the hose toward the groove I39.

The hose is prevented from going into this groove first by reason of the diflerence in depth of the groove, and as this difierence in depth approaches zero, the hose is prevented from crossing by means of the flange I; however, at the point where this flange terminates, the hose will be free to cross over into groove I39 and be taken up in that groove. It is to be noted that the effect of the rollers must be such as to urge the hose toward groove I39 but it must not be sufllcient to force the hose into this groove in spite of the depth of groove I31 or the flange HI.

It has been found that the rollers 2| must beof substantial length and diameter, and spaced from rolls I43, so that bending of the hose in 55 the retrieving operation will not be so severe as to either prevent it from crossing into groove I39 at the proper time or to compel it to cross over into said groove before the proper time.

pipe and the packing gland shown in Figure 4.

The pipe 5|, before it is fixed to the other pipe,

can be provided with the packing gland 51 and 5 nut 59 and be dropped down into the nipple 43.

After the pipe 5| is connected with the rest of.

the pipe, the packing 55 can be supplied and the packing. gland can be drawn down by nut 59 to make a tight joint at this point. The air re- 10 lease and pumpingassembly can be readily removed by reversing the process.

It is obvious that various changes may be made in the form, structure and arrangement of parts without departing from the spirit of the invention. Accordingly, applicant does not desire to be limited to the specific embodiment disclosed herein primarily for purposes of illustration; but instead, he desires protection falling fairly within the scope of the appended claims.
