COIN-CONTROLLED APPARATUS FOR INFLATING TIRES.

Application filed March 31, 1916.

To all whom it may concern:

Be it known that I, Ensures R. /VIN sLoW, a citizen of the United States, residing at Thirty-second street and Avenue B, Kearney, in the county of Buffalo and State of Nebraska, have invented certain new and useful Improvements in Coin Controlled Apparatus for Inflating Tires, of which the following is a specification.

This invention relates to coin controlling apparatus for inflating tires and has for one of its objects the provision of an apparatus operable only when a coin of the proper denomination is inserted in the inclosing casing of the apparatus.

Another object resides in the provision of an apparatus which may be installed within a garage or other building or in the front of a garage or anywhere along a roadway for the supply of air to inflate automobile, bicycle or other tires without the necessity of employing a caretaker and which is rendered operable and the air accessible to a motorist or others upon the insertion of a coin of the proper denomination into the casing.

A still further object is to provide an ap-.

paratus of the nature stated, embodying among other characteristics, a casing provided with an air storage chamber into which air may be forced under pressure and in which apparatus the air supplying means may be arrested and stopped automatically when the full capacity of the'storage chain ber has been reached.

It is still further designed to provide an apparatus for inflating tires embodying a casing provided with a normally locked door and in which casing is confined a tire inflatingtube and means operable to supply the air necessary for the inflation of the tires and in which the door may be unlocked and the inflating tube withdrawn from the casing only upon the insertion of a coin of the proper denomination into the casing, the door being movable to closed position and locked automatically and the supply of air to the inflating tube cut off when the operator has no further use for the inflating tube and releases the same.

With he above and other objects in view, the present invention consists in the combination and arrangement of parts hereinafter more fully described, illustrated in the Specification of Letters Patent.

cas-

ema n d Referring now more particularly to the accompanying drawings, 10 indicates a casing of any suitable material and which may be of any form in cross section and in which, intermediate the top and bottom thereof, is disposed partition 11 to form an air storage chamber 12.

The casing 10 is provided with a closure 13 and between the closure 13 and the partition 11 is disposed a second supporting partition 14: on which is fixedly secured an electric motor 15 and a pump 16 operatively connected to the motor by means of a suitable driving connection 17. The motor may be connected up with any suitable electrical circuit and operation of the pump 16 by the motor- 15 draws air from the atmosphere through the pipe 18 extending through the closure 13. The compressed air from the pump 16 is conveyed into the storage chamber 12 through. pipe or other suitable means 19 which leads through the partitions 11 and 1%.

When the air delivered to the storage chamber in the manner just described has reached the pounds pressure capacity thereof the electric motor may be stopped by the switch controlling mechanism A of any suitable character designed to open and close a suitable switch B. In the use of the switch controlling device A illustrated herein, the excessive air pressure passes from the storage chamber 12 through the pipe 20 into the lower end of a cylinder 21 supported by the partition 14- and acts against the piston head 22 held normally toward the lower end of said c -linder 21 b means of sirin 23 which encircles the piston rod 2%. The upper end of the piston rod 2 projects through a bushing 25 in the upper end of the cylinder 21.

An arm 26 is fixedly secured to the projecting end of the piston rod 2 1 and at its outer end is directed downwardly as indicated at 27 As the excessive pressure forces the piston head 22 and consequently the piston rod 24 upwardly against the action of said spring 23, the arm 26 is forced upwardly into engagement with a roller 28 journaled in one end of a curved lever 29 pivoted at 30 on a support 31 secured by means of rivets 32 or otherwise to the side of the cylinder 21.

A shelf 33 is supported above the supporting partition 1%, and a weighted lever 3% has its lower end pivoted at 35 'to the shelf 33. This weighted lever 3a is provided with teeth 36. A curved weighted lever 37 is pivoted at 38 to the shelf 33 adj acent the pivot 35 of the weighted lever 3-iand the extremity 39 of the curved portion of the weighted lever is adapted to normally engage between the teeth 36 of the lever 34 to hold the latter normally in an inclined plane against the action of the spring e0 which connects the lower end of the lever 29 with the lever 34:.

A hook 41 is adjustably secured to the aforesaid curved lever 29 and has its bill 1-2 arranged to engage a lateral projection L3 011 the curved weighted lever 37 so that when the arm 26 engagesthe roller 28 on the curved lever 29 and thereby wings the latter on its pivot 30 the hook 41 brings its bill A2 into engagement with said lateral projection 43 of the curved weighted lever 37 and releases it from cooperative engagement with the teeth 36 on the weighted lever 3%. Immediately upon the release of the weighted lever 3 in the manner ust stated, and by virtue of the spring connection between the weighted lever 3 1 and the curved lever 29, the weighted lever 3 1 is swung on its pivot 35 to the left to a position slightly beyond the vertical eil'ecting operation of the electric switch B, thereby stopping the motor. Thus, it will be seen that the said mechanism A controls the switch B, operating the same when the capacity of the air storage chamber has been reached.

The electric switch mechanism B may be of any suitable character, but the one illustrated embodies a fixed terminal l3 secured on the shelf 33 by a suitable binding post and a swinging contact member 15 pivotally connected at 46 to the relatively short upright 47 and with which swinging contact member the binding post 48 has operative electrical connection.

A spring 49 is connected. at one end to the said relatively short standard 4:7 and at its opposite end to the swinging contact member 45, normally tending to swing the contact member 4-5 on its pivot i6 away from the fixed contact 423, but this normal tendency of the contact 15 to swing is prevented by a holding element 51 carried by the lever 34 to bear against the yieldable element 50 on the swinging contact Thus, when the lever 3% is swung on its pivot 35 in the manner stated, the spring 19 will disconnect the contact members 13 and 45 and thereby break the circuit, between the motor and the switch and thereby shut off the motor, and maintain the storage tank 12 always filled with compressed air.

When the piston head '22 lowers in the cylinder 21 under the influence of the spring 23, and which it will do as the pressure in the storage chamber 12 falls below normal, the inclined edge 27 of the downwardly directed end 27 of the arm 26 will engage the lateral projection 3 1 on the weighted lever 31 to push the same to the right to a point slightly beyond the vertical when the weighted end of the lever 3 5i will cause the latter to fall and the part 51 to engage the yieldable element 50 of the swinging contact 15 and tirow the latter into engagement with the fixed contact 43 to thereby close the circuit and start the motor to bring the pressure in the storage chamber 12 to normal.

The supporting partition 11 is provided with a central screw threaded aperture 52 in which is screwed a plug 53 having a central passage The plug. 53 extends above the supporting partition 11 for the connection therewith of the hub C of a wheel 55 whose periphery is flanged, as indicated at 56, for a purpose presently explained.

The hub G includes the cup shaped portion 57 adapted to loosely receive the bushing 58 provided with a depending screw threaded collar 59 for a screw threaded fit with the upper end of the said plug 53. This bushing 58 and its collar 59 remain stationary with the plug 53 while the cup 57 of the hub C is adapted to rotate around the bushing 58 and its collar 59, there being a bushing 60 fitted in the cup 57 above the bushing 58 and having screw threaded connection with the cup.

The bushings 58 and 60 have air passages 61 and 62 respectively which are arranged in alineinent with each other and with the air passage 54 in the plug 53. The bushing 60 has a projecting bearing 63 which is embraced by the lower end of a sleeve 64: whose upper end is connected to the under side of the supporting partition 14:, the sleeve being adapted to steady the wheel 55 or to maintain a substantially true horizontal rotation of said wheel.

A flexible tube 65 of suitable length is adapted to be wound onto and oil of the flanged rim 56 of the wheel 55 for the purpose of conveying the compressed air from the storage tank 12 to a tube or tire (not shown) for the purpose of inflating the lat ter. To this end the flexible tube 65 is connected in any suitable manner to a rigid or other tube 66 which leads from the flanged rim inwardly to the hub C oit'the wheel. into communication with the passage 67 in the bushing of the hub and which passage has constant communication v-.* ith thepassages 51, 61 and 62, so as to establish communlcation between said tube 06 and the storage chamber 12.

The passage 54 has a tapered valve 68 i dition on the wheel is normally inclosed within the casing 10 against access and the valve 68 normally maintained closed, until a coin of the proper denomination is deposited in the casing to permit the actuation of check controlled mechanism D.

To the end, just alluded to, the closure 13 of the casing 10 is provided with slots 69 and 70, the slots 69 communicating with a coin chute '71 whose lower end leads to a coin holding device 72. The coin drops through the chute 71 into the coin holding device 72 where it is held adjacent one end of a hollow tube 73 slidably nounted in supports 71 and 7 5 secured to the part on 14. One end of this tube 73 is held normally adjacent the coin holding device 72 by means of a spring 7 6 which connects with the tube 73 and with the support 7 1. I

It a. slug be inserted into the chute 71 the magnet 77 on the lever 7 8 pivoted 7 9 will be attracted and drawn through the slot 80 in the chute 71. The pivotal movement of the lever 78 will cause a linger 81 carried thereby to engage the slug holding lever 82 and cause the finger 88 thereof to be pro jected through the slot 8 1 in the coin chute 71 and hold the slug in the chute above the coin holding device 7 2, partly projectel out of the slot 69, and thereby prevent operation of the check controlled device. The slug projecting partly out of the casing through said slot 69'may be readily grasped and withdrawn.

if a coin other than the proper denomination be dropped into the chute it will pass entirely through the same and beyond the end of the tube 73 and through a slot 85 in a shelf 86.

'It a coin oi the proper denomination be dropped into the chute 71 it will pass into and be arrested by the coin holding device 72 adjacent the right hand end of the sliding tube 73 and held in position adjacent the right hand end of the tube for engagement by the bar 87 slidably mounted in the standards 88 mounted on the partition 11. This bar 87 is held in normal'position with its handle 89 normally adjacent the outer end of the aforesaid slot 70 in the closure 13 by means of a suitable spring 90. lhe coin held in the coin holding device 72 is engaged by the inner end of the bar 87 when the handle 89 is grasped and the bar 87 given a sliding movement in the supports SS against the tension of the spring 90 and t 1e tube 73 is then slidably moved in the supports 71 and '75 against the action of the spring 7 0, the coin or proper denomination being eventually dropped into the receptacle 91 as will be explained.

A vertically swinging lever 92 has a sliding pivotal connection 93 with the tube 73. This lever 92 extends through the slot 1 1 in partition 11 and is pivoted at 91 on the bracket 95 depending rom the supporting partition 1% and at its lower end said leve 92 has sliding movement in a short slot 96 in one end of horizontally swinging lever 97 pivoted intermediate its ends at 98 on a bracket 99 secured to the aforesaid sleeve (34. The lever 97 has spaced ears 100 in whicha dog 101 is pivoted and which is adapted to engage the toothed ra k 102 on the aforesaid wheel 55 for a purpose presently explained.

The lever 97 is adapted in the performance of one of its functions to effect an unlatching and a swinging movement of the door 108 or" the casin 10. This door 103 has its hinge 101 provided with a crank arm 105 which has pivotal connect-ion with a link 106 loosely connected in the slot 107 in the end of the lever 97. Fixedly secured. to the slotted end 107 of the lever 97 is a latch operating bolt 108 which is loosely connected at 109 to a pivoted bell crank latch 110 adapted to engage in the keeper 111 on the door 103 to maintain the latter normally locked.

Thus upon sliding movement of the tube 73, the lever 92 is rocked on its pivot 91 and its lower end fitting in the slot 96 in one end of the lever 97 causes the latter to swing horizontally on its pivot. The swinging movement of the lever 97 causes the latch bar 108 to rock the latch 110 on its pivot to disengage the latch from the keeper 111 and immediately upon the unlatching of the latch 110 the connection 106 between the lever 97 and the arm 105 of the door hinge 10 1 causes the door 103 to swing to open position on its hinge to permit access to the casing 10 through the door opening. is the door is opened, under the influence ot' svvinging movement of the lever 97, the

dog 101, being swung with the lever 97 and being in engagement with the toothed rack 102 of the wheel 55, gives the latter a slight rotative movement substantially equal to the distance of swinging movement of the door.

The flexible tube has its valved tire engaging nipple 112 disposed normally against a loop shaped member 113 carried by a rock shaft 11% journaled in suitable brackets 115. Then the door 103 is opened this rock shaft 114: is rocked against the tension of the spring 116 to turn the loop 113 to such position that the valved nipple 112 of the flexible tube 65 may be readily grasped to pull the tube 65 and rotate the wheel 55.

As the loop 113 is swung outwardly in the manner just stated, it engages the upturned end 117 of a valve stem 118 connected to the tapering valve 68 mounted in the aforesaid bushing 53 so as to rotate said stem 118 against the action of the spring 120 and thereby rotate the tapering valve 68 to bring the port 121 thereof into registration with the passages 5-1, 61, 62, and 67 in the hub of the wheel 55 and thereby permit the passage of compressed air from the storage chamber 12 into and through the tube 66 and into the flexible tube 65 for discharge from the latter into a tube or tire to inflate the same.

The rock shaft 114 has a crank arm 122 at its upper end which slidably en ages in a slot 123 in the arm 124: of a bell crank lever 25 pivoted at 126 and whose arm 127 is provided with a shoulder 128 adapted to en gage behind the aforesaid lever 97 after said winging movement of same, andthereby hold the lever 97 to prevent accidental closing of the door 103.

The wheel 55 carries a trip 128 which is adapted to engage the aforesaid dog 101, after the latter has given the wheel 55 its said initial movement, and lift the dog on its pivot onto the aforesaid horizontal lever 97 where the dog remains until it is engaged by a projection 129 depending from the upporting partition 14:, and upon engagement with which, the dog 101 is thrown on its pivot from the top of the said horizontal lever 97 to operative relation with the rack 102 on the wheel 55. lVhile the dog 101 is in its upper position on the lever 97 the trip 128 does not engage the same because the trip passes under the lever 97 during rotation of the wheel. When the door 103 of the casing 10 is closed the lever 97 is swung on its pivot 98 to a position where the dog 101 will be brought into contact with the trip arm 129 which will throw the dog down on its pivot 01f of the lever 97 into cooperative relation with the rack 102 of the wheel 55.

When the door has been opened, the motorist or other person pulls on the slightly advanced flexible tube 65, rotating the wheel 55 until a sufficient length of flexible tube has been withdrawn from the casing 10 as will enable the appllcation of the valved nipple 112 of the tube 65 to be coupled with the valve of the tube or tire to be inflated. During thi withdrawal of the flexible tube from the casing 10 the operator must hold on to the tube because if he releases his hold on the same the tube will be retracted into the casing under the influence of reversed rotation of the wheel 55. In other words, when the wheel is rotated in one di rection by a pull on the flexible tube 65, the wheel is rotated forward against the tension of a spring 130 connected to the tube 6-1 and to the hub C of the wheel 55. Consequently, upon release of the tube 65 the spring 130 will rotate the wheel 55 in a reversed direction and consequently draw the tube into the casing, winding it on the wheel. The valved coupling nipple 112 of the flexible tube 65 is of such size that it cannot be drawn through the loop 113 of the rock shaft 11% whereby the valved coupling nipple 112 i always accessible when the door 103 is open.

An indicator E is mounted on a suitable bracket 130 in the casing 10. This indicator is designed to register the number of coins of the proper denomination inserted into the apparatus and may be of any suitable construction, preferably that cha *acter which embodies one or more rotatable disks, actuated by a pawl 131 engaging the toothed disk or disks to rotate the same one step upon the insertion of each coin of the proper denomination. As shown, the pawl 131 is pivoted on a swinging rod 132 whose lower end is arranged to be engaged by the upper end of the lever 92 so that as the latter is swung on its pivot 91 in the manner already stated, the upper end of said lever will swing said rod 132 to cause the pawl 131 to rotate the disk one step. On the reverse swinging movement of the lever 92 the upper end of I the same engages the lower end of the rod 132 which swings the latter, but on this backward swinging of the lever 92 and the consequent swinging of the rod 132 the pawl 131 rides over the teeth of the disk and does not rotate the disk.

The operation of the apparatus may be stated briefly as follows:

A coin of the proper denomination is dropped into the chute 71 through the slot 69 and falls into the coin holding device 72. The handle 89 is grasped and moved in the slot of the closure 13 to slide the bar 87 a ainst one side of the coin whose opposite side is held in the coin holding device 72 against one end of the tube 73. The tube 73 is thus slidably moved in the standards 7- l and by the aforesaid sliding movement of the bar 87 and the coin interposed between the tube and bar, the sliding movement of the tube being against the tension of the spring 76. Unless the coin be interposed between the tube 73 and the bar 87 the apparatus could not be operated because the bar 87 if moved toward the tube 73 would project into the same.

When the handle 89 reaches the inner end of said slot 70, the handle 89 of the bar 87 is released and the spring 90 retracts the bar 87 to normal position. The tube 73, however, is held in locked position because of the vertically swinging lever 92 being connected to the tube 73 and being eventually locked against return swinging movement. To this end the vertically swinging lever 92 is connected to the tube 73 and caused to swing in a vertical plane on its pivot 91 as the tube 73 slides. The lower end'of the lever 92 being connected with the horizontally swinging lever 97, the vertical swing ing movement of the lever 92 causes a horizontal swinging movement of the lever 97 on its pivot 98. The dog 101 being pivotally connected to the lever 97 and normally in mesh with the toothed rack 102 on the wheel 55, the latter is given an initial rotative movement as the lever 97 is swung. This lever 97 in its swinging movement operates the latch 110 to unlatch the door, and by virtue of the connection 106 between the lever 97 and the arm 105 on the hinge of the door 103, the door is swung open under the horizontal swinging action of the lever 97.

The rock shaft 111 is rocked under the in fluence of the spring 116 when the door opens and the loop 113 moves forwardly toward the door opening and engages the stem 118 of the valve 68 and rocks the latter to throw the port 121 of the valve into alinement with the air passages 5st, 61, 62 and 67 in the hub of the wheel admitting compressed air into the flexible tube 65.

The rock shaft 111 has an arm connection 122 in the slot 123 of the bell crank lever 125 and as the shaft 11% rocks it causes its said arm 122 to swing said bell crank lever 125 on its pivot 126 and force its shoulder 128 against the lever 92 to hold the door 103 in open position and the aforesaid tube 73 locked against accidental return movement.

The flexible tube 05 may now be pulled upon and applied to the tube or tire valve to inflate the same. The pulling action on the flexible tube rotates the wheel and the trip 128 on. the wheel engages the dog 101 and throws the same up on top of the lever 97.

Assuming that the operator is through with the flexible tube 65, he releases the same. T he spring 130 connected to the hub of the wheel 55 causes the latter to rotate in the reverse direction which draws the flexible tube 65 back into the casing onto the wheel through the door opening until the valved nipple 112 of said tube engages the loop 113, said valved nipple being pulled against said loop 113 causing the rock shaft 111 to rock against the action of its spring and immediately upon the loop 113 being released from engagement with the projection.

117 on the shaft 118 the valve 68' is closed under the influence of the spring 120.

The rocking movement of the shaft 116% causes its arm 122 to trip the bell crank lever 125 to remove the shoulder 128 of the latter from behind the lever 92 when the lat ter will assume its normal position under the influence of the spring 76 which also returns the tube 73 to its normal position. As the lever 92 assumes its normal position it swings the lever 97 which operates the crank arm 105 on the door 103 and closes the latter and also effects automatic latching of the latch 110 in the keeper 111. When the lever 97 is thrown in such a position as to close and latch the door 103 the dog 101 is tripped by the trip arm 129 and thrown down to operative relation with the toothed rack 102 on the wheel 55.

The electric motor 15 continues to operate the pump 16 to supply the storage chamber 12 with compressed air through the pipe 19 until the full capacity of the chamber 12 has been reached when the excess pressure will pass through the pipe 20 into the cylinder 21 and thereby actuate the switch mechanism B, in a manner which has already been explained, to shut off the current and thereby stop the motor when the chamber 12 ms reached its full capacity.

Th re are times when it may be desired to dispense with the storage chamber 12, in which event, as shown in Fig. (i, a flexible tube 133 is connected with the-lower end of the pipe 19 and with the passage 54 of the plug 53 so that the air from the pump 16 may be supplied directly to the passage 54 by way of said connection 133. The switch mechanism A-B before described, is dispensed with, and a switch mechanism F is substituted therefor. This second form of switch mechanism F consists of a fixed contact 13a and a swinging contact 135. The swinging contact member 135 is in a form of a bell crank pivoted at 136 and its arm 137 is held normally out of contact with the fixed contact 138 connected to the arm 137 and to a post 139. An arm 1410 is secured to the sliding tube 73 and carries a cam 1 11 at its free end adapted to ride upon the arm 1412 of the bell crank shaped contact member 135 and through the same on its pivot 136 against the tension of the spring 138 into engagement with the fixed contact 134: when the tube 73 is moved in its bearings 7 1 and to shift the lever 92 and through the instrumentalities connected with the latter to actuate the various parts of the apparatus before described, including the opening of the door 103, the pump 16 is operated. to supply the air to the inflating tube 65 as should be well understood.

In both forms of the invention the electric motor is shut oil under the influence of movement of the tube 73 and in both forms of invention, it may be stated that there is a connection between the pipe 19 and the passage 54: in the plug 53 for the reason that the storage chamber 12 forms such a connection as does also the connection 133.
