Referring in detail designates. a service station-in the form of apparatus for vending oil, gas and water to motorists, and for like purposes. Said stato the drawings, 10 I tion comprises a metal casing 11 secured to the grooved or other suitable base 12, at its lower ed e portion 13. Said casing comprises a ront ,wall 14, side walls 15,\16 .and a top wall 17. The latter wall may be rounded or otherwise suitably shaped for ornamental purposes. Mounted on'said top wall 17 is lamp 18 of any'suitable attractive construction for illuminating or advertising purpose. At the lower rear portion thereof, said casing is formedf-with an-extension 19 having an opening 20. A door 21 hinged at its upper edge 22 may be locked to said casing as by lock 23 shown in Fig 2.

In the front face 14 of saidv casing are a number of slots for receiving coins for controlling the operation of the dispensing devices. The kind of liquid dispensed and the character of the coins to be inserted are in dicated by suitable markings adjacent the respective slots. Thus at the left of 'said front wall, a slot 25 may be marked Oil. and 1 Quarter. Secured to said front wall 14 below said slot, and extending rearwardly from said wall is an elongated horizontal sleeve 26 of rectangular cross-section. A coin guide member 27 communicating with slot 25 leads down to said sleeve 26 which is provided with a slot 28 for permittingthe coin deposited in said slot 25 to drop into said sleeve.

Mounted within said sleeve 26 is a rack 29 having gear teeth 30 formed at the lower edge thereof. An elongated plate 31 is slidably mounted within said sleeve 26 in par allel relation to said rack 29. Integrally formed with said plate 31 is an elongated stem or rod 32 extending within said sleeve and thru a slot 33 formed in the front wall 14 of the casing. Said rod 32 terminates in a handle member 34 for reciprocating said plate 31 within said sleeve 26. An upstanding arm portion 35 integrally formed with Said plate 31 at one end thereof, is adapted. to ride in slot 36 formed in the upper wall 37 of sleeve 26 and serves to limit the movement of said plate 31 in both directions. A projection 38 fixed to the inner face of said plate 31 extends between said plate and rack 29. A pair of spaced projections 39 intogrally formed with said rack 29 extend in- Wardly from the inner face thereof, substantially in alignment with said projection 38. Extending beneath said plate 31 which is of less height than the sleeve 26, is a wall 40 slidably supporting the plate 31. It will now, be understood that a. coin 41 inserted thru slot 25 and passing downwardly thru guide 27 and slot 28 will drop on said wall 40 and between the projections 38 and 39. Should this occur, a pulling force on the handle 34 will cause sliding movement of both plate 31 and rack 29 since these members are interlocked by the coin 4'1 abutting the projections 38 and 39. Should the coin. 41

be smaller than the space between the upper and lower projections 39. the projection 38 will merely push said coin thru said space and the rack 29 will hence not be moved by pulling the handle 34. Extending beneath said sleeve member 26 is a. coin guide ,inined quantity of oil when a proper coin has been inserted inslot '25 and the rack bar moved as described above. To this end,'a gear 45 is rotatably mounted on shaft 46, a one-way roller clutch 47 being interposed between said gear and saidshaftQ Fixed to said shaft 46 is a plate 48 adapted to be rotated only when the rack 29 is being moved forward toward wall 14., Return movement of the rack will only rotate gear 45 without affecting either shaft 46 or the plate 48. Said return movement of the rack 29 is effected by a coil tension spring 49 fixed on its bottom end 50 in any suitable manner within the easing and connected to the rear end 51 of plate 31 as by a belt 52 rolling over a pulley 53. A pin and slot connection 54 between the plate 31 and rack bar 29 is adapted to return said rack bar to the position shown in Fig. 6 when said plate is moved to the right under the influence of tension spring 49.. The relative sizes of the gear 45 and rack 29 is such that a single forward stroke of the plate 31 will cause complete revolution of said plate 48. Mounted on a bottom supporting plate 55 fixed within the casing 11 adjacent edge portion 13 is a cylinder 56,- disposed directly beneath said plate 48. Within said cylinder is a piston 61 having a piston rod 62 extending thru a suitable opening 63 in the top wall 64 of said cylinder. A connecting rod 65 pivotally connects said piston rod 62 and an ec entric pin fixed to plate 48 as at 66 and 67 respectively. Mounted within the casing 11 as on plate 55 is an oil. barrel 68 supported within said casing 11. in a slightly inclined position as shown in Fig. 1 of the drawings. interconnecting the barrel 68 and the bottom of the cylinder 56 is a short pipe 69 having a one-way check valve 70 interposed therein for a purpose hereinafter appearing.

The front wall 14 of casing 11 is provided with an opening 71. Mounted on the inner surface of said front wall adjacent the lower edge of said opening is a trough member 72 having a bottom wall 73. Flow-off or drip pipe 74 interconnects the bottom of said trough with the top portion of the barrel 68. Mounted on said bottom wall 73 is a container 75 adapted to be inserted thru the'opening 71 of front wall 14. A handle member 76 may he provided for manipulating said container 75.

A retrieving mechanism 77 is provided for drawing said container 75 back into its position as shown in Fig. 6 when said container has been withdrawn from said/opening and released after use. Said retrieving mechanism 77 comprises a drum 77a rotatably mounted on a shaft 78, said shaft and drum being interconnected by a spiral spring 79. A chain 80 is adapted to wind on the outer surface of said drum and interconnects the latter with the container 75. A pipe 81 connected to the bottom of the cylinder 56 extends upwardly and terminates in a downwardly curved portion 81a disposed directly above the container 75. A one-way check clear. The purchaser need merely insert a coin in slot 25 for interlocking plate 31 and rack member 29. If the coin is too large, it

will not enter the slot 25.' If it is too small it will not interlock with said members 29 and 31. If the coin is of the proper denomination, said members will be interlocked and the plate 48 given a complete revolution. This movement of plate 48 will cause the piston 61 to reciprocate vertically in the cylinder 56.

. On the upstroke of the piston, oil will be rack 29 to the normal position.

drawn in from the barrel 68 thru pipe 69 and check valve 70 and, on the down stroke, the oil will be forced out thru check valve 82,-

Said register is preferably mounted on the front wall 14 directly above the sleeve 26, and may be provided with'a pivoted arm 86, the end portion 87 of said arm extending in, the path of an upstanding projecting "87a" formed with rack 29. Upon movement of said rack forpumping oil-, the arm 86 will I thereby be movedfor actuating the register. A spring 88 is adapted to return the arm86 to its original position upon return of the Said register may be further provided with a disc 89 adapted to rotate progressively as the arm 86 is actuated. Saiddisc 89 is formed .with

peripheral notch 90. Pivotally mounted on a fixed shaft 91 is a bell crank 92 having an arm 93 maintained in contact with the periphery of disc 89 as by a light spring 94. The upper portion 95 of said bell crank is adaptedto support a plate 96 which slidably extends within the 'sleeve 97 fixed to the .front face of wall 14 above slot 25. When the disc 89 hasbeen rotated a complete revolution, by a predetermined number of oscillations of arm 86, the end portion 93 of the bell crank 92 will enter the notch under the influence of spring 94. This movement will disengage the upper end of said bell crank from the plate which is thereby permitted to drop behind the slot 25 forobstructing the same. Further deposit of coins will not thereafter be possible until prop readjustment of the parts. The register 85 may be so adjusted that the plate 96 is caused to obstruct the slot 25 when the oilbarrel 68 is substantially empty.

The service station 10 is further provided with means for dispensing gasoline. To said end, a gasoline tank 100'is preferably embedded in the ground beneath the casing 11 in the usual manner. Said tank is connected to an ordinary gasoline hand pump 101 by a pipe 102. A crank handle 103 extending beyond said casingis fixed to a shaft 104 rotatably mounted within the casin and extending thru said wall 16 thereof: Fixed on said shaft 104 are spaced gears 1 05 and 106 which mesh with a pair of vertical racks 105a and 106a interconnected by a cross bar 107. Said racks extend into the pump 101 and are adapted when moved upwardly by rotation of handle 103- in the proper direc-. tion to pump gasoline thru thepipe 108 and a hose 109 mounted in a manner hereinafter described. v I

A coin control mechanism is provided for permitting the purchaser to pump predetermined quantities of gasoline. Forthis purpose the front wall 14 in the casing is provided with two coin slots 110, 111. One of said slots 110 may be marked Half dollar and the other slot 111 may be marked 2 Dimes. Extending inwardly from said wall 14 below said slots 110, 111 are horizontal sleeve members 110a and 111a respectively. Coin chutes 110?), and 1116 provide passages for coins from said slotsto the interior of sleeves 110a, and 111a respectively. Slidably mounted within said sleeves 110a, 111a are plates 112, 113, respectively. Said plates 112, 113-are provided with stems 112a, and 113a respectively, extending thi'u openings 112b and 1136 in a front wall 14 and terminating in heads 1120, 1130. Said plates 112, and 1.13 are formed with vertical slots 114, respectively'on the inner faces thereof. Slot 114 is adapted to receive the half dollar de posited into slot 110. Should a coin of a smaller denomination be inserted in slot 110,

said coin being thinner than the half dollar will drop thru a slot 116 formed in the bottom wall 117 in sleeve 110a. Slot 115 in plate 113 is'adapted to receive the dimes in serted thru-slot 111. The height of the plate 113 is equal to the height of the two dimes as clearly shown in Fig. 3. Tension springs 116a secured to the rear end portions 112d, 113d ofsaidplates 112 and 113are adapted to normallyretain said plates-in retracted position as shown in Figs. 3 and 5. Rotatably mounted on a shaft 117 a journaled in bearing brackets 118 fixed to wall 14 are a air 1 20. Lever 119 is provided with an arm 119a having an ofi-set portion 1196 and an extension 1190 projegting into the lower portion of slot 114. Likewise, lever 120 is provided with an arm 120a having an off-set portion 120?) and an extension 1200 projecting into the upper portionof slot 115. It will now be of substantially symmetrical levers 119,

understood that upon insertion of the proper coin into-chute 1106, the coin dropping into slot :114 will be interposed between the end ortion 112d and plate 112, said extension 1190 of the lever 119.- When the half dollar I Thus, should. a smaller coin be inserted in "126 at its lower end slot 110, the coin would not be retained within said slot 114 by said projections 121, but would fall thru slot 116. Likewise, when the two dimes. are inserted in slot 111 and said dimes are lodged within slot 115, one above the other, the upper one of said dimes is interposed between the extension 1200 of lever 120 and the end portion 113d of plate 113. A pulling force on head 1130 will hence cause pivotal movement of the lever 120. The lower dime may be supported by a pair of spaced projections 122 formed at the inner surface of said-plate 113. Obviously, if only one dime is inserted into the slot 111, said dime would be ineffective to interlock the plate 113 and the lever 120. Upon out-ward movement of either of plates 112, 113 the coins are brought into alignment with the coin chutes 124 and 125 respectively'whence the coins are conveyed to the coin deposit box 44.

Means are provided for preventing operation of the pump 101 until the proper coins have been deposited in slots 110, and 111, and for preventing the purchaser from pumping more than a predetermined quantity of gasoline, corresponding to the coins deposited.

, Attached to lever 1.19 adjacent the off-set portion 119?) thereof, is a depending integral arm 126 ext-ending below said sleeve members 110a, 111a. Pivotally attached to said arm portion 127 as by a pin and slot connection 128, is a horizontal slidably mounted member 129. The latter com-- prises a bar 130 mounted on a pair-of fixed aligned guides 131 disposed on either side of the shaft 104. Formed with said bar 130 are a pair of symmetrically spaced horizontal U-shaped members 131, 132, and slidably mounted within member 131 is a plunger 133 having a pin and slot connection 134 with said member. A coil compression spring 135 interposed between the rear end of said plunger and wall 136 of said member 131 normally maintains said plunger in extended position, as shown in Fig.3. Attached to the cross bar 107 which interconnects the racks 105a, 106a is a vertical depending member 137 disposed in alignment with said U- shaped members 131 and provided with one way ratchet teeth 138 adapted to engage a tooth portion 139 formed at one end of plunger 133.

Thus when the parts are in the position illustrated in Fig. 3, turning movement of the handle 103 for pumping gasoline is prevented since the racks 105a, 106a connected to the pump mechanism within pump 101', canno move upwardly due to the locking lnteren gagcment of teeth 138, 139. However, when the lever 119 is rotated in clockwise directlon as seen in Fig. 3, the bar 130 is translated to the left for releasing member 137. Said member 137 is further provided with oneway ratchet teeth 140 disposed in a direction opposite to teeth 138. A plunger 141 slidably mounted in U-shaped member 132 1n a manner similar to the mounting for plunger 133 is provided with a tooth 142 and adapted to interlock with said teeth 140 of member 137 upon movement of the bar 139 to the left. Such movement of course, takes place when the lever 11.94 is rotated in clockwise direction topermit actuation of the pump for dlspensing the gasoline. Thus, actuation of the pump handle in a direction for moving the racks 105a, 106a downwardly is prevented while the bar 130 is moved to the left. As will hereinafter be pointed out, said bar 130 will be automatically moved to the right only when the full and proper amount-of liquld has been pumped.

Attached to the upper ends of levers 119, 120 as by a pin and slot connection 150, 151 are a pair of stop members 152, 153 for limiting the upward movement of ratchet member 137 and consequently the actuation of the pump 101 for dispensing the gasoline. Said stop member 152 comprises a horizontal arm 154, an upstanding vertical arm 155 extending from one end of said arm 154,, and a horizontal arm 156 extending from the upper end of said arm 155. Said arm 154 1s slidably received in, the guide member 157, whereas the arm 156 is slidably received in a guide member 158; Actuation of the lever 119 will thus cause reciprocation of said member 152. The stop member 153 comprises a horizontal arm 159, a depending vertical arm 160 and a horizontal arm 161 extending from the lower end of said arm 160. Arm 159 of said member 153 is likewise slidably received in the guide member 157, whereas thearm 161 is slidably received in a guide member 162 simila r to and spaced directly below said guide member 158. Said arm 154 of member 152 is provided with a slot 163- wherein is received at the right end thereof as shown in Fig. 3, a pin 164 fixed to the inner surface of arm 159. It will now be understood that rotation of lever 119 will move member 152 to the right without moving member 153. However, upon rotating the lever 120, both members 153 and 152 will be moved to the right since pin 164 Which is fixed to arm 159 contacts a portion of arm 154 at the end of slot- 163. Thus, lever 119 is rotated in a counterclockwise direction upon actuation of either plate 112 or 113.

The arm 156 is provided with a ramped member -158 is a ball 16.8 normally pressed against upper surface of said arm l56.by spring 169. Formed in the upper surface of said arm 156 is a notch 170 adapted to receive the lower portion of said bell 168 upon movement of saidmember 152 to the right, for retaining said member against accidental movement. A tension spring 171 fixed at one end 172 thereof, attached to said member 152 at its opposite end, normally tends to move said member 152 to the left. Arm 161 is, likewise provided with a ramped portion 165a and notch 170a for receiving a spring pressed ball 168a.

Upon insertion of a half dollar in slot 110, the coin drops thru chute 110?) into slot 114, thus interlocking the extension 1190 of lever 119 with plate 112. The plate may then be pulled outwardly for rotating lever 119 in a clockwise direction. Such rotation will release plunger 133 from engagement with the ratchet member 137 and will simultaneously move member 152 to the right, bringing the ramped portion 165 and extension 166 directly above cross member 107. This movement will also cause the spring pressed plunger 141 to abut teeth-140 of said ratchet handle 133 may then be rotated for pumping liquid but not in a reverse direction. During such pumping action, the gears 105, 106 meshing with rack 105a, 106a, will move the cross member 107 upwardly. This movement, which is now permitted since the plunger 133 is retracted, may then continue until said cross membermember. The pump 107 strlkes the ramped portion 165 of member 152. Upon contact with said ramped portion 165, the member 152 will be caused to slide slightly and to the left causing the ball 168 to be lifted from the notch 170 and thus permitting the spring 171 to move the member 152 to the left, and thereby rotating lever 119 in a counterclockwise direction to again bring plunger 133 into contact with ratchet 137. Further pumping is thereafter prevented, and the pump handle must be rotated in the opposite direction to again lower the ratchet member 137 before any pumping action may again take place. Upon" insertion of 2 dimes in slot 111, the same aption takes place except that and120 are rotated simultaneously (due to the pin and slot connection 163, 164) Thus the'lower arm 161 is brought into alignment above with the bar 107 and only the lesser uantity of liquid can 'then be pumped. QlVhen the bar 107 strikes the ramped portion 165a of the arm 161, a similar unseati'rrg action ofthe spring pressed 'ball 167axtakes place to permit return movement of member 153 under the influence ofj'tension spring 171a. At the end, such return movement of member 153, the pin 164 moving in the slot' 163 in arm .154 strikes said arm for unseating ball 168 to permit retraction of memboth levers 119 her 152 by spring 171. It will be notedthat the purchaser will not be able to rotate the handle 103 for lowering the bar 107 until said bar strikes either arm 161 or'156.

The hose 109 for receiving gasoline is wound on a drum 175provided with a retrieving spring 176. Thus, before starting the pumping operation, drawn by pulling the nozzle 177 and inserting the tip of said nozzle within the propergas tank opening. Said nozzle is provided with a small bell crank 17 8 which is movable by pin ing the hook end 17 8a of said bell crank to engage the undersurface of the gas tank adjace'nt the mouth while the gas is being pumped. The 'nozzle is thus rigidly suppkprted in themouth of the gas tank while t e After the full quantity of liquid hasbeen pumped, pin 179 may be pushed downwardly for releasing the bell crank 178. Upon being released, the nozzle may then be drawn back to the casing since spring 17 6 will then wind the hose 109 on the drum I7 5.

Coin control means is provided for vending water. To this end, the front wall 14 of the casing 11 isprovided with a slot 180 marked \Vat er. Below said slot may be designated the coin to be inserted as for instance 1 Nickel. Secured to said wall 14 is a coin chute 181 for guiding the coin deposited in said slot. A bell crank 182 pivotally mounted beneath the outlet opening 183 of said chute is provided with an arm 1'84 adapted to receive thecoin 185 as shown in Fig. 8. Said bell crank is provided with a second arm 186 adapted to contact the rear portion of said coin. Attached to said front wall 14 is a tubular member 187 having an opening 188 in the end wall 193 thereof. Slidably mounted within said tubular member and extending thru said opening 188 and an opening 190 in said front wall, is a plunger 189 having a fixed collar 191 extending within said tubular Infill?! 187. A coil compression spring 192 in erposed between the hose is with- 179 connected thereto for causpurchaser is operating the handle 103.

iiially presses said collar against the rear surface of said front wall 14. Said plunger is further provided with a portion 194 extending beyond said wall 14 and having a head 195. It will now be obvious that upon pushing the plunger 189 inwardly against the pressure of the spring 192, the force is trans.- mitted thru the coin 185, thus causing clockwise rotation of the bell crank 182. v The coin thereafter drops into any suitable receptacle. If no coin has been inserted in the slot 180, the inward movement of the plunger will not affect the bell crank. Mounted.

drum 198.- Said drum peripheral helical groove is provided 199 for thec with a 1 water hose 200. The inner end 201 of said hose is connected to, a valve 202, which may be connectedthru a pipe 203 to any suitable water-supply under pressure. Pivotally attached to said valve 202 is an actuating member 204, the mechanism being such that rotation of said member 204 in a counterclockwise direction will open the valve to permlt flow of water from the hose. A spiral spring 205 normally maintains the hose in wound condition on the drum, the nozzle 206 of said hose being normally drawn against the front wall 14 of the casing. Arm 184 of the bell crank 182 is provided with a detent 207 adapted to engage within the groove 208 formed in a tubular portion 209 adjacent the nozzle of the hose. Thus the hose cannot be drawn out while the detent 207 extends within the groove 208. However, upon the insertion of a proper coin in slot 180, rotation of the bell crank 182 may be effected for lifting the detent and for permitting with-- drawal of the hose.

Means is provided for automatically pivoting the actuating member 204 fromthe normally valve closing position shown in Fig. 8 upon drawing the hose out to start the flow of water. To this end, an .end wall 210 of the drum 198 is provided with a spiral groove 211. A pin 212 fixed to a block 213 slidably mounted on the actuating member 204 extends into said groove 211. Upon drawing the hose from the casing, the drum 198 rotates and the pin 212 moves. inwardly towards the center of the drum because of the spiral groove 211. When said pin'212 contacts the portion of the wall 210 on the inner end of the spiral groove, as designated by numeral 214, further outward movement of the hose will rotate said actuating arm 204 for opening the valve 202. The nozzle 206 obviously may be inserted in the automobile radiator opening. After use of the water, release of the hose will permit the retrieving. spring 205 to rewind the hose and close thewater valve and bring the parts to their original position.

Although the oil and gasoline pumps shown herein are hand operated, it is understood that electric motors or the like means may be provided for actuating said pumps.

It will thus be seen that there is provided a deyice in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use. r

As various possible embodiments might be made of the above invention, and as various changes might'be made in the embodiment set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
