Specification of Letters Patent. Patefited Aug, 3O, 1921 Application filed August13, 1919. Serial No. 317,294.

T 0 all whom it may concern:

Be it known that I, JOSEPH l3. MCMUL- LIN a citizen of the United States, residing at (5skaloosa, in the county of Mahaska and State of Iowa, have invented a new and useful Hose-Reel, of which the following is a specification.

This invention has reference to hose reels, and'its object is to provide a reel and hose particularly adapted for use in connection with supplying air under pressure for the inflation of automobile tires, but is at the same time susceptible of other uses.

The invention comprises a hose reel and stand therefor, which stand may be of a character to permit it being located at or adjacent to a street curb so that the hose may be withdrawn from the reel for the purpose of connecting the hose to automobile tires for inflating them, the arrangement being such that on releasing the hose the latter will automatically re-wind upon the reel in accessible but protected position. Ordinarily the hose is under the control of locking means whereby indiscriminate use of the hose is prevented and by providing a coin lock the assurance is had that the hose will only be used as needed and not be open to malicious use.

In order that the public may be notified of the service provided, a. suitable sign, visible either in daylight or at night, may be carried by the stand and in addltion thereto a gage is provided indicating the air conditions available.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming partof this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims. a

Fig. 11 is Fig.10. a

' casting.

Fig. 12 is a section on the line i21;2- of Fig. 10. Referring to the drawings there is shown a base 1 which may be a casting of any suit-.

able shape or be otherwise formed than by The base 1 is designed to be mounted on a pavement near a curb or at any other suitable point. Rising from the base 1 is a column 2 whichmay also be a casting or 'be of other suitable formation and this column mergesinto a casing 3, which, being intended to house a hose reel 4, is of cylindrical shape in most part, to

avoid waste of material, although the hose.

reel casing 3' need not necessarily be of such shape. Moreover, the casing 3 may be offset laterally with respect to the column 2, because of certain parts which are located within the column to one side of the hose reel 4. Various mechanisms are located within the column 2 and easing 3, and for convenience of manufacture and to properly protect such mechanisms as well as to integral part of the casing. The plate 7 is providedwith an axialstud 8 from which a section on the line 11+11 of render them readily accessible whenvdesired,

to the stud and extending toward the-other face or coverplate 5. Mounted on the arthere projects anarbor 9 in'fixed relation bor 9 is a hub 10 carried by roller bearings 11 between the hub and the arbor. One end of the hub has an inturned flange 12 for confining a set of roller bearings 10 and there is another set of such roller bearings near the opposite end of the hub, separated from the first-named set by a spacing sleeve 13.

The outer end of the hub 10 is internally screw-threaded to receive a hollow plug 14 and this plug is closed at the outer end by another plug 15 leaving a chamber 16 between the two plugs. At one side of the plug 14 there is formed a nipple 17 to which is screwed a pipe 18. The arbor 9 is provided with an axial passage or bore 19 extending throughout the greater portion of its lengt and opening at the outer end of the arbor close to the plug 14. Screwed into or soldered in the open end of the bore 19 is a pipe or tube 20 extending into the chamber 16 through the base of the plug 14 and packed, where passing through the bottom of the plug 14, by suitable packing material 21 held in place by a gland 22. In this way the hub 10 may readily rotate about the arbor 9 without danger of leakage between the bore 19 and the chamber 16 and with free assage of air from the bore to the chamber.

ormed on the hub is a radial circumferential flange 23 carrying an annulus 24 forming one face plate of a hose reel. Attached to the face plate 24 by means of rivets 25 and spacers 26, or in any other suitable manner, is another annulus 27 forming the opposite face plate or wall of the hose reel. The arrangement is such that the hose reel is supported by the one flange 23, although formed of two spaced face plates so located as to receive a hose 28 between them.

When the hose is wound on the reel it forms a spiral as is customary. One end of the hose is extended through and held by a li 29, shown in Fig. 3, while the other end of the hose carries a nipple connection 30 such as shown, described andclaimed in my application Number 310,144, for tire pump connection, filed July 11, 1919.

The casing 3 is provided at a suitable part of it, say, at the upper portion near one side, with an outstanding neck 31 through which the hose 28 is carried, and a ball 32 or other stop meanson the hose outside of guiding and retaining rollers 33 in the neck 31 prevents the complete indrawing of the hose into thecasing 3 and also avoids injury to the nipple connection 30, leaving the latter exposed to an extent permitting it, to be grasped by the hand of the user. The pipe 18 at the end remote from the plug 14 is connected to the inner end of the hose 28 in a manner that the pipe 18 and hose 28 are, always in communication. Since the pipe 18 rotates with the hose reel such connection is never .broken and no strain occurs on the parts. j

The hub 10 is provided with a circumferential series of gear teeth 34 which are elongated in the direction of the, length of the hub to facilitate the making of the casting. At one point the continuity of the teeth is broken by a circumferential groove 35 to accommodate a circumferentially elongated tongue 36 formed on the inner surface of a shield 37 overlying the gear teeth on the hub. This shield is made fast to the stud 8 by screws 38 or otherwise. Meshing with the gear teeth 34 is agear wheel 39 carried by a drum 40 inclosing a spiral spring 41. The drum 40 with the spring 41 is mounted upon a hub 42 in turn carried by a spindle 43 projecting from a boss 44 on the inner face ofthe plate 7. The arrangement is such that as the hose is withdrawn, from the hose reel the hub 10 is rotated and through the gear teeth 34 and gear wheel 39 the spring drum 40 is also rotated, thus winding the spring 41, which latter, when the device is originally installed, is placed under some tension, at least sufficient to retract the hose after having been pulled out from the casing 3 for use. One face of the drum 40 is provided with a spiral groove 45 shown in Figs. 3 and 4 and in this groove there is engaged a pin 46 projecting from one arm 47 of a lever 48, the pin 46 being located about midway of the length of the arm 47. Formed on the grooved face of the spring drum 40 is a socket 49 containing a compression spring 50 serving as a buffer, this sprin being in the path of the, pin 46 at one limit of its movement along the groove 45. When the hose 28 is fully retracted the pin 46 is at the socket 49 and engaging the spring 50 lodged limit of its movement toward the left as seen" in Fig. 3. When the hose is withdrawn from the reel, the spring drum is given a clockwise movement thereby causing the groove 45 to propel the pin 46 and with it the arm 47 toward the right. A stop 51 in the column 2 limits the movement of the arm 47 toward the left in Fig. 3. In the path of the outer or lower end of the arm 47 which end is provided with an antifriction roller 52, is a beveled extremity 53 of one arm 54 of a rock lever 55 having the other or short arm 56 at an angle to the long arm 54 so that the lever 55 is in the nature of a bell-crank lever.

The purpose of the lever 55 is to cause the actuation of a valve structure 57 shown on a small scale in Fig. 3 and on a larger scale in Figs. 10, 11 and .12, to which reference is particularly had in the following description of such valve. The valve 57 comprises a casting including two chambers 58 and 59 respectively,which may be arranged side by side for convenience of construction and compactness. The chamber 58 ispermanently closed at one end and at the other end is closed by a screw plug 60. The interior of the chamber is provided with a series of circumferential grooves 61 all joined along the side toward the chamber 59 by a groove 62. lVithin the chamber 59 there is lodged a cylindrical screen 63 including all the grooves 61 and at one end opening through a port 64 into a pipe connection 65 to which a pipe 66 is made fast. The pipe 66 is intended to and may be assumed to-be connected to a source of air under compression, such as is provided at the usual air stations. The chamber 58 is connected to the chamber 59 through a port or passage 67 intermediate of its length.

' Within the chamber 59 there are located two washers or packing members 68 and 69 respectively. The packing member 69, which may be in the form of a rubber washer, is lodged against a shoulder 70 formed in the wall of the chamber 59 and the packing member 68 is lodged against a screw plug 71 forming a closure for the corresponding end of the chamber 59. The two washers 68 and 69 are separated by a spacing sleeve 72 which also serves in connection with the plug 71 to tightly lodge the two washers in the chamber 59 against the possibility of leakage by them. The spacing sleeve 72 has an exterior circumferential groove 73 and this groove is connected with the interior of the sleeve at intervals by passages or ports 74 so that the interior of the sleeve has free communication with the groove 73. Through the wall of the chamber 59 there is a port or passage 75 with which there communicates a pipe 76 ultimately connected to the bore 19 of the arbor 9, as shown in Fig. 4. Extending through the plug 71 is a rod 77 also extending through'the packing washers 68 and 69 into that end of the chamber 59 with which the port 67 communicates. The washer 69 has a conical face 78 forming a valve seat for a valve 79 engaged by the neighboring end of the rod 77. The valve 79 is constantly urged toward the valve seat 78 by a compression spring 80 between the Valve and the inner wall of the chamber 59 remote from the plug 71. The last-named end of the chamber 59has a port 81 therethrough terminating in. a nipple 82 which, by means of a coupling 83, is made fast to a pipe 84, which latter, as shown in Figs. 2 and 3, is carried up through the casing 3 and into a post 85 to a pressure gage 86 near the upper end of the post' and so arranged as to be readily visible to an observer who may at any time ascertain the pressure within the pipe 84. The post 85 is surmounted by a globe 87, which may be of glass or other suitable light-transmitting material, containin-g insignia 88 to indicate the purpose ductedinto the tire.

angle of the whole structure. In the special instance shown in the drawings, the insignia consists of the words Air service thereby informing the reader that air for charging tires or the like may be obtained from the device. Within the globe 87 there is contained an electric lam 89 fed by current delivered through a cont ucting cord 90 coming from any suitable source of electric supply.

The end of the rod 77 outside of the chamber- 59 has a screw-threaded portion 91'carrying a nut 92 which may be utilized as an abutment for the arm 56 of the lever so that when the lever 55 is actuated by thearm 47 the rod 7 7 is moved through the washers 68 and 69, causing a like movement of the valve 79.

The rod 77 adjacent to the end engaging the valve 79 has a longitudinal bore 93 with branches 94 and 95 leading to the exterior of the rod. The branch 94 opens into the interior of the spacing sleeve 72. The branch 95 opens into the interior of the valve 79 which is chambered for the purpose. WVhenever the valve 7 9 is opened there is communication between that portion of the chamber 59 communicating with the pipe 8t and the pipe 76. In this manner air under pressure from the source of compressed air may be conducted, when the valve 79 is opened, into the chamber 58 through the screen or strainer 63. thus preventing anything but clean air entering the chamber 58 within the screen 63. This air then passes by way of the port 67 into the compartment 59 from which the clean air passes by the valve 79 through the ports 95. 93 and 94 respectively, to the pipe 76 which finally conveys the air to the hose. and. assuming that tie latter is withdrawn and applied to the valve. nipple of an automobile tire, the air is conis indicated on the gage 86 by way of the tube or pipe 84, chamber 59, passage 67, chamber 58 and pipe 66.

While the lever 48 may be actuated or controlled in any suitable way, by hand or otherwise, it provides a convenient means whereby coin-controlled mechanism may be utilized, such mechanism being best shown in Figs. 6 to 9 inclusive. I

At asuitable point within the casing 3 is located a compartment .96 entered by and containing a coin chute 97. The coin chute in the particular showing of the drawings is upright, although this is not at all obligatory, and below the coin chute there is located a stud 98. Mounted on the stud is one end of a pendent rock arm 99 having an extension or finger 100 normally so situated as to be in line with a series of notches 101 in the outer margin of the face plate or annulus 24, whereby the face plate 24 is in effect a ratchet wheel and the finger '100 serves as a ratchet acting as a stop preventing rotation of the hose reel in one direction but permitting it to rotate freely in the other direction. Mounted on the stud 98 is a rock lever 102 shown separately in Figs. 7 and 8. The lever 102 has a passage or perforation 103 about midway of its length fitting the'stud 98. At one end the lever 102 is provided with an expanded plate-like head 104 with a perforation or passage 105 therethrough. At the other end the lever 102 has an angle extension 106 from the extremity of which there is an angular projection 107. Adjacent to the projection 107 the extension 106 carries a stud 108 serving as a pivotal mounting for a latch plate or trigger 109 held to the stud by a screw 110 or otherwise. The latch plate 109 is held yieldably in a desired osition by a spring 111 and adjacent to t e spring carries a laterally projecting pin 112. The arm 99 is connected to the lever 102 by a spring 113.

Mounted inthe compartment 96 so as to project through the wall of the casing 3 is a push-button 114, having a stem extension 115 projecting into the chute 97 but normally out of the path of a coin inserted in the cute. A spring 116 on the stem of the push-button 114 is arranged to hold the latter in the normally projected position accessible to an operator. The stem extension 1151s in line with the passage 105.

The lever 48 has an arm 117 at an angle to the arm 47 and said arm 117 terminates in a laterally expanded cam head 118 extended into the compartment. Fast to the hub 42 to which the spring 41 is secured, is an arm 119 whereby the initial tension of the spring 21 may be adjusted. To hold the arm 119 in any desired position of adjustment,

the free end of the arm carries a screw 120 capable of setting in any one of a series of perforations or sockets 121 in the casing 3.

In considering the operation of the hose reel structure, it may be assumed that the structure is mounted in accessible position, say, adjacent to a street curb and that the spring 41 is suitably adjusted and the hose 28 1s wound on the reel within the casing 3 with only the nipple connection or chuck 30 exposed for access. If, now, a person des1r es to use the hose for inflating a tire, a suitable coin is dropped into the coinchute 97 and its progress is arrested opposite the head 104 of the lever 102 in the path of the stem or extension 115 of the push-button 114. If no coin be introduced the push-button may be manipulated, and the stem 115 will pass freely through the perforation 105 and perform no function. With the coin in place, pushing on the button 114, causes the coin to engage the head 104 and thereby rock the lever 105 against the action of the sprin 111. The lever 102 engages a lug 122 on the arm 99, thus rocking the latter in a direction to clear the finger 100 from the particular notch 101 in which the finger rested, so that the hose reel is no longer locked but may be freely turned. As the lever 102 is'moved in the manner described the latch plate or trigger 109 is brought into engagement with another lug 123, thereby holding the arm 99 and lever 102 in the position to which they have been moved by the push-button114, and on release of the push-button it is returned to the first or projected position by the spring 116. The coin originally engaged by the push-button then drops through a slot 124 out of line with the coin chute and may find lodgment in a suitable coin box. The hose reel being thus released permits the withdrawal of the hose to any needed extent and the rotation of the hub 10 causes the winding of the spring 41 through the intermediary of the teeth 34 and the gear wheel 39. As the unwinding of the hose proceeds with the corresponding winding of the spring 41, the spiral groove 45 on the spring drum, by engaging the pin or stud 46 on the arm 4( causes the roller 52 to ride along the beveled edge 53 of the arm 54 of the lever 55, thereby rocking the arm 56 in the direction to move the rod 77 sutficiently to open the valve 79. Now, air under pres sure coming from a suitable reservoir, not shown, through the pipe 66, may fiow into the chamber 58 and out therefrom through the port 67, being in the meantime cleansed or filtered by the strainer 63. A portion of the air flows by way of the port 81 through the pipe 84 to the gage 86, thus indicating the air pressure. Another portion 81 of the air passes around the valve 79 through the ports 95, 93' and 94 to the pipe 76,, and thence to the passage 19, tube 20, chamber 16 and pipe 18 into the hose 28. However, the air cannot esca e from the hose becaus of the presence of the chuck or nipple coupling 30. This chuck is of a character permitting the passage of air from the hose into the inner tube of the tire when applied to the inner tube nipple, but automatically closes as soon as the chuck is removed from the inner tube nipple. During this time the hose is held extended against the pull of the spring 41. As soon as the operator is finished with the hose he has but to let go of it, whereupon, the expansion of the spring 41 causes a turning of the hose reel and a rewinding of the hose thereupon until further movement of the hose is stopped by the engagement of the enlargement 32 with the rollers 33. The re winding of the hose causes the reverse movement of the arm 47 of the lever 48 and a corresponding reverse movement of the arm 117 and the head 118, which latter then engagesl g the latch plate or trigger 109 and releases it from the stop '123, thus permitting the lever 102 to return to its first position and the arm 99 to also return to its first position together with the lever 1 02. The'fingerlOO is, by this operation, moved into a notch 101 thereby preventing a re-withdrawalof the hose from the reel and lock the parts all in the first position from which they-maybe released only by the deposition, of another coin.

,WVhile theugage 8(5- and lamp 89 may be supported in various ways it is preferred to provide a lug 123 projecting inwardly in the column 85 and this lug is provided with a passage. to accommodate the bolt 124 threadedlinto, the back of the casing of the gage 86,; thereby holding the latter in the column: ,locknut 125 servesto-hold the artsfirmly togetheivandvalso to clamp one egof anangle bracket 1-2.6 to the lug 123,
