AUTOMATIC REGISTER FOR IiIQUIlDS.

Patented June 6, 1922.

Original application filed March 19, 1920, Serial No. 367,045. Divided and this application filed March 5,

To all whom it many concern:

Be it known that EMORY SUDLER and CHARLES E. SUDLER, citizens of the United States, residing at Tarrytown, in the county of Vvestchester and State of New York, have invented certain new and useful Improvements in Automatic Registers for Liquids, of which the following is a specification.

The present invention relates to quantity and value indicating means for gasoline filling pumps and constitutes a divisional por-' tion of our parent: application, Serial No. 367045. 7

The principal object of the invention is to provide a device which will automatically indicate the amount and value of liquid dispensed, enabling the consumer to ascertain for himself the exact amount of liquid received by him and correspondingly the cost of this amount.

Another object of the invention is to provide quickly detachable and replaceable computing dials carrying indicia to prominently display the current price of the liquid in conjunction with the indicia which indicates the amount and value of liquid dispensed.

Other objects of the invention will be apparent from the following description taken in connection with the accompanying drawings, wherein:

chamber ,9, upon which is superimposed a The device of this invention consists of a stand generally designated 7, in the present instance being of substantially cylindrical configuration and formed to provide a base 8, intermediate measuring receptacle or ment to the shaft 38.

Serial No. 449,690.

casing 10. The casing 10 is shown in the drawlngs to be formed integral with the receptacle 9, and preferably is made of metal. Since it is necessary that the contents of the receptacle 9 be visible, a transparent panel, (not shown in the drawings) may be mounted in the receptacle. Or, if desired, the receptacle may be made of glass or other transparent material.

Arranged beneath the stand 7 is a gasoline worklng tank 11, which has communicating therewith a liquid supply pipe 12, and a vent pipe 13. Both of these extend upwardly through the base 8, as does also a compressed air plpe 14, the three pipes engaging a valve 15 whlch-is arranged at the juncture of the receptacle 9 and base 8.

A float 35 is movably mounted in the meassuring tank 9, and is guided in its movement through the receptacle by

pipes

16 and 17 which extend through suitable openings in the float. A rack bar 36 extends upwardly from said float and into the casing 10. Movement of the rack bar is adapted to impart movement to computing mechanism carr ed in the casing'lO. This mechanism QOIlSlStS of a main shaft 38 which is secured in the casing 10 and has loosely mounted thereon a gear wheel 39, the latter carrying a spring pressed pawl 40. The pawl is adapted for engagement with a ratchet 41 which 1s fixedly carried by the shaft 38. The gear wheel 39 is in mesh with a pinion 42 which latter is carried by a stub shaft 43, the stub shaft carrying a gear wheel 44 which is in mesh with the rack bar 36. From this construction it will be apparent that upward movement of the float" will not impart move- Reversely, however, downward movement of the float will be communicated through the train of gears to the shaft 38, causing rotation of the same and corresponding rotation of a graduated computing disc 45 which is carried thereby. The gear 39 may also be connected with other mechanism if desired, such for in stance, as a registering device to register the number of gallons of liquid dispensed from the measuring receptacle 9. On the upward movement of the float, the shaft 38 is held from movement by a pawl 70 and ratchet 71, the former being pivoted to a fixed part, (not shown) in the casing 10, and the latter secured to the shaft 38.

The computing dial 45 has gradnationsaround its entire circumference, the aggregate of which may be any multiple of the capacity of the measuring chamber 9. The ratio of the

gears

39, 42, 44 andrack bar 36 may be so arranged that a full'downward stroke of the float 35 will cause only a fraction of a revolution of each gear wheel. Thus, the-dispensing of the complete contents of the measuring receptacle will rotate the dial 45 only a partial revolution. Consequently, should the measuring receptacle hold only ten gallons and a customer desired thirty gallons, three full receptacles could be successively dispensed and their aggregate amounts indicated on the dial 45. However, if a customer should desire only a quantity equivalent toor less than the capacity of'the measuring receptacle, or even if he receives one or more full measures of the receptacle plus a fraction of the capacity of the latter, mechanism is providedto automatically return the dial to a neutral or zero position. This mechanism consists of a hook member-46, one end of'which is sleeved on a fixed shaft 47 The free end of the member is formed to provide a bill 48 which is adapted to receive a ring 49 attached to the end of a dispensing hose 18. The-bill is normally held'in its uppermost position by a spring 50 which is convoluted on the shaft 47 and has one end secured to the member 46 and the other end engaged with a fixed part 51 of the casing 9.

An arcuate arm .52 is formed on the member 46 and has teeth on its inner margin on the shaft38 attached to the pinion 53,

is secured thereto, and carries a spring 55, one end of which is turned outwardly to provide an abutment 54. A bell'crank'lever 57 is pivoted on the dial 45 and has one end normally held inthe path of the abutment 54 by a spring 58. Theopposite end of said lever is in pivotal connection with a bolt 59 which is slidable through a sleeve 60. The bolt is limited in its movement in the sleeve 60 by an offset car 61. One end of'a strap 62 is secured directly above the sleeve 60 and is either secured to or made an integral part thereof. The free end of said strap is flexed outwardly from the dial 45 in superposed relation to the bolt 59 and-has its terminal reversely folded to form a stop 63. This stop will, at times, be in the path of movement of a lug 64, which is formedon the member 46, to stop movement of the dial in a manner subsequently set forth.

A' charge indicatin dial is carried by the quantity indicating ia-l 45 and has charges inscribed thereon which are commensurate with and alignment with' the registered.

amount o f-- gasoline; dispensed. Therefore, the quant ty of gasoline-and. its charge-will be: vlstmhzedz through. an: opening. 65 in a cover plate 66, of the stand 7. This plate is removable to permit the charge indicating dial to be changed so as to harmonize with fluctuations in prices charged. The daily rice of the gasoline will be displayed centrally on the charge indicating dial as indicated at 67. This charge will be discernible through a transparent'opening 68 in the cover plate.

As is no doubt apparent from the above, gasoline is introduced into the receptacle 9 through the pipe 12. Action of the float 35 controls the dispensing of the liquid from the receptatcle 9 through the discharge hose 18. WVhile the gasoline is being dispensed from said receptacle through the discharge hose the computing mechanism automatically operates in the manner above described so as to indicate the quantity and value of the liquid or gasoline dispensed. After the liquid has been dispensed in this way the ring 49 of the discharge hose 18 is hung upon the bill 48 of the hook member 46. The weight of the discharge hose on said bill causes the member 46 to move downwardly in the are of a circle, thus rotating the pinion 53 and disc 56 through somewhat more than a complete revolution. Since this pinion and disc are free to rotate on the shaft 38, this movement does not rotate said shaft or the dial plate 45 as the latter is fixed to said shaft. In view of the fact that the dial 45 remains stationary after the discharge hose is hung on the hook, it will be apparent that the quantity and value of the liquid dispensed will be discernible to the customers served, this indication being retained until the discharge hose is removed from the hook. However, assoon as the discharge hose is removed from the hook to serve the next customer the spring-50 causes said hook member 46 to move upwardly, thereby rotating the spring 55 through an arc somewhat in excess of a complete revolution. At some 'point during this movement, depending upon the position of the dial 45 at that time, the abutment 56 will engage the bell crank lever 57 and exert pressure thereon so as to impart movement to the dial 45, until the projection 63 comes in contact with the lug 64, thus bringing the dial to a stop at the neutral or zero posltion.

Since the upper face ofthe lug 64 is formed as an arc of a circle, drawn from the center of the shaft 47, it is obvious that although the dial plate is brought-to a stop, in the manner above set forth, said lug will be carried by the hook member 46 further 11pwardly along the lower lateral margin of the strap 62 and will impinge the outerend of the sliding bolt 59. This bolt will-be causedato mOVe through the sleeve 60 there by rotating the bell crank lever on its .pivot to disengage it --from theabutment 5.4 ofe-the spring 55. This will release'the dial 45:.and

permit it to again rotate on the next downward movement of the float 35. Of course, during the upward movement of the hook member 46, the proportion of the parts will permit the lug 64 to have movement sufficiently far to the right of the projection 6;) to clear the latter. In this way danger of said projection being engaged by the lug during further rotation of the dial 4.5 will be eliminated until the discharge hose has again been hung upon the hook. Also, as a precautionary measure, the projection 63 is resilient to permit its flexure if perchance the lug 64 should contact therewith when the hook member 46 moves'downwardly.

Various changesmay be made in this device, especially in thedetails of construction, proportion and arrangement of parts within the scope of the appended claims.

What is claimed is:-

1.
