In my prior application, referred to above, I have disclosed and claimed a dispensing pump, such as is used for gasoline and other liquids, which has connected therewith an indicator and counter and an adjustable non-slip driving mechanism for driving pinion 27 therefor.

May 17, 1920. Serial in. 381,869.

operating said indicator and counter from thev drive shaft for the pum As explained m that application, the cy inders for such pumps are not absolutely uniform in size and for-this and other reasons, it is necessary to adjust the length of stroke of'the various pumps in order to discharge a definite quantity of the liquid to be dispensed. This makes it necessary to adjust the drivmg connection between the pump mechahim and the indicator and counter in order that the movement of the indicator and 7 or slip between the driving mechanism and the counter in order that as soon as the pump beginsjto operate, the counter will be- .gin to register the liquid which is bein discharged. The operator of a pump, such This application is a division of my prior application," Serial No. 193,257, filed Sep is-on the other side, and consequently itis desirable to provide an indicatin' dial on each ofthe op osite sides of t e' pum'.

The. customers ial 10 is shown more clear in"'Fig.,4,'and the operators dial 11, whicl comprises simply a pointer 12, is shown in Fig.1-.'--The customers dial is also provided with a pointer 13 which is mounted on a common shaft 14Jwith the other pointer 12.

Secured to the operating shaft 15 of thepump isa plate 16"formed with outwardly curved slots 17 in which pins 18 are slidable. Thesepins are secured to arcuate' segments 19 andthe segments may be moved radially outward from the axis of the shaft '15 by a relative movement of the plate 16 and the segments 19. To one of the segme'nts'a fiexi ble band 20, preferably of metal, is secured by means of a fastening device 21. This bandor ribbon 20 is wound upon and Se I I cured to a drum 22 which in turn is rotatably mounted upon 'a'hub portion 23 of a fixedplate 24'. the face of which plate constitutes the dial 10. Secured to the plate a 24 and the drum. 22 is a spring 25 which .tends to keep the band 20 taut and to draw the lost motion ump and the n the plate 24 and extending ,around the graduations o the dial 10, is a-circular slot 28 through upwardly on it to take 11 between the rack 26 of (no which projects a pointer 29 extending from the ribbon drum 22. At one 'end of the slot is the designation and at other points.

the pointer .29, it being obvious that the rotation of the gear 35in one direction causes pointer will assume these positions upon the actuation of the pump rack because of the connection of the band 20;

Freely rotatable on the hub of the member 24:, between it and the ribbon drum'22,

is a Geneva stop gear 30 which has'lugs 31 adapted to be engaged by a projection 32 of the ribbon drum 22. This gear also has rearwardly extending toothed portions 33 which are spaced from the lugs 31. At the bottom of the plate 24, as shown in Figs. '2 and 3, is a Geneva pinion 3 1 with which the gear 30 engages .torotate the pinion a predetermined amountupon each engagement of the toothed portion 33 with the pinion. As the particular pump illustrated is a two gallon measure and as it. may be set to pump either one or two allons at each stroke, it is obvious that the eneva pinion must be moved twice for a full stroke of the pump; in other words, .ifthe ribbon drum 22 is simply rotated until the pointer 29 rachesthe one gallon mark, the stop 32 will engage only the uppermost lug 31, Fig. 4, which will move the lowermost toothed portion 33 to engage the pinion 3 1 but if the stop 32 is movedthe entire length of the slot 28 both toothed portions 33 will engage the pinion 34, causing it to be twice. actuated. Of course, the reverse rotationof the Geneva stop gear 30 engagesthe pinion 34 and moves it backwardly the same amount so that the gear 30 is simply oscillated back and forth one ortwo unit spaces by the engagement of the stop 32, depending upon the length. of stroke of the pump. "Meshing with the pinion 34 is a gear 35 which carries a pawl 36 and this pawl engages a ratchet gear 37 fixed on the shaft 14. The

' the pawl 36 to actuate the ratchet gear 37 and cause a corresponding rotation of the pointers 12 and 13 which are attached to the shaft pawl 36 is moved reversely and idly over the gear.

* The ribbon drum 22 is preferably formedwith a hub extension 40 upon which is freely mounted a driving gear 41. Between this gear and the ribbon drum 22 is a springpressed roller clutch 42 which causes the rotationof the gear 41 when the ribbon drum is rotated in one direction. Between in one thefixed' member 38 and. the gear 41 is a roller clutch 43' which prevents the rotation of the gear ll in the reverse direction. Meshing with the gear ll is a spur and bevel pinion 44 which isdirectly connected by a driving member. 15: with a register l6 visible from the outside of the casing. As the driving gear 4:1 is actuated only in one direction of rotation and as the mechanism described is a single-action pump, it is obviousthat the register will accurately record cate. The dials 10 and. 11' are preferably the pointers 12and'13 can be freely rotated direction to set them at-the zero points. a This is desirable forthereason that when a customer buys a quantity of the liquid dispensed, thev pointers are set at zero marks and the operation "of the pump, as above described, will cause the actuation of the pointers to record the units of the quantity pumped whereupon the pointers can again be set upon the zero marks without in any way effecting the quantity register 46 which records thetotal amount. pumped.

In varying the length of stroke of the pump rack to insure the accuracy of the "the total amount discharged by the pump .even though an insuflicientquantity has I been discharged to cause the units registers at the front and rear ofthepump-to indipump, it is obvious that the graduation *ofv the slot 28 would not remain the same for the different lengths of stroke that is, if the 19 which are attached to the plate 16, forby moving them inwardly and outwardly, the length of the path of travel of the pointer 29 may be varied whenever the length of stroke of the pump rack is varied so that the pointer will always register with the graduations of the slot, thereby insuring also that the total register 46' will accurately record the amount pumped.

Briefly stated it may be said that the segments 19 will be moved inwardlywhen the length of the pump stroke is increased. and vice versa. The reciprocation of the rack 26 causes the actuation of the unitsregistering mechanism which records the number of units of measure (gallons) of the fluid umped and also the-actuation of the regisibring counter which thereupon measures the entire discharge of the pump pump were set so that the pointer 29 would regardless ofthe number of units measure pumped. The various adjustments for'the accuracy of the pump 'are,'of eourse, made whenever necessary, it being observed, however, that with this style of pump it is unnecessary to have any access-whatever to the interior of the easing of the pump in order to effect the ordinary operation thereof.

In the modified form of the invention shown in Figs. 5, 6 and 7, a pump, casing '50 is illustrated having a shaft 51 journaled thereinand arranged to be rotated by a hand crank 52 to operate a pinion 53. The pinionf53mesh'es with and drives a ump rack 54' which operates-a pump cy inder in a well'known manner. Meshing with the pinion 53 is a second pinion 55 rotatably mounted on 'a stud shaft 56 and secured to a sleeve 57 which carries a sprocket wheel 58. A sprocket chain 59 engages the sprocket wheel-5.8 and passes around an expansible-drum 60. Instead of providing an intermediate gear 55 and stud shaft 56, the sprocket wheel 58 may be mounted directly on the pump shaft 51. This will eliminate any back lash or lost motion that may be present between the intermeshing gears 53 and 55. The side links 61 of the sprocket chain 59 are provided with comparatively fine notches or serrations 62 which cooperate with similar serrations-63 on the adjustable segments'64 of the drum 60. The segments 64-are provided with tongues mounted to slide in grooves 65' formed in the face of a plate 66. The face of the segments 64 opposite' the plate 66 are provided with pins 67 which extend into inclined slots 68 formed in a cover plate 69. Screws 70 pass through elongated slots 71 in the plate screws.70,are .loosenedj and the plate'69' '69 and are threaded into the plate 66. To

adjust the diameter of the, drum 60 the slightly rotated relative tothe plate 66. This willforce the-pins 67 toward or away from xthecent'erfof the drum, depending upon the direction ofrelative rotation of the plates 68 and '69.,When the drum is adjzusted' 'tothe proper diameter the screws 0 are again tightened and. clamp the plate 69 and segments 64 in fixed position relative 'to the plate 66. The plate 66 is provided'with a projecting hub portion 72 which extends into a circular recess in a rotary member 73. Ratchet rollers 74 are provided between the members 72 and 7 3 to constitute a one-way drive between the plate 66 and the rotary member 73. The

rotary member 73 is seated in a recess formed by a fixed flange 75 on the pump casing 50 and ratchet rollers 76 constitute a one-way .holding ratchet between the members 73 and 75. lVhen the drum 60 is driven by the sprocket chain 59, during the pumping stroke of the rack 54, the projection 72 on the plate 66 will operate the secured to the rotary elements in the man- 125 rotary member 73 through the ratchet drive 74. On the reverse stroke of'the rack 54 the member 7 3wi11 be held against rotation ,by theratchet rollers 76 and the projection 72 will rotate freely in a reverse direction in the recess in the member 73. The member 73.is provided with a sleeve 77 rotation 79 is connected by suitable gearing 80.

to any well known form of counter. By this arrangement the counter will be driven durin but Wlll remain stationary during the idle stroke of the rack. chain-tightener comprising a roller 81 carried by an arm 82 pivotally mounted on a pin 83 is provided for maintaining constant tension in the driving run of the chain 59. The tension on the chain 59 is produced by a spring 84 which bears upon the arm 82on the side of the pin 83, opposite the roller 81 g In the form of expansible drum shown in Figs. 8 and 9, a plurality of segments 85 are provided with tonguesv 86 arran ed to slide in grooves 87 in a plate 88. he

plate 88 is provided with a projecting hub 89 threadedto receive a cone 90 which extends into a central opening in a cover plate 91 and bears against the inner faces of the segments 85. A spring 92 is housed-in a recess 93 in the segments 85. and. normally draws the segments 85--against the beveled face of the cone 90.. Screws 94 pass through openings in the plate 91 and'are threaded into the plate 89. To adjust the diameter of the drum,thescrews 94 are loosened and the cone 90 is rotated on the threaded hub 89 to cause it to move in or out'and thus shift the segments 85 to adjust the diameter of the drum. When the desired diameter has been secured, the screws 94 are again,

tightened to hold the segments. in their adjusted positions. The construction of this form of drum may be in other respects the pumping stroke of the rack 54.

similar to that. shown in. Figs. 5, 6 and 7.

It will be understood that the drum shown in Fig. 2'may be provided with expansion 'mechanism. similar to that shown in either Fig. 7 or Figs. 8 and 9, and that the form of flexible driving element shown in Figs. 8-' and '9 ma shown in ig. 1.
