Be it lrnownthat '1, EDwAnD B. Hnvn,

a citizen of the llnited States, residing at ongmeadow, in the county of l'lampden and State of Massachusetts, have invented new and useful mprovements in Registers, of which the following-is a specification.

This invention relates to improvements in l'egisters of the type which are intermittently actuatecL-usually from a machine, to give cumulative indcations of the extent of motion of some part of themachine.

The inventfion according to most of its features, is capable of a variety of uses and is thus. la'rgely independent of the particular use to which it is put.

The invention, however, finds one advantageous use in connection with the Wellknown measuring and dispensing pumps, which are generally used in connection with the sale of gasoline and lile Aoils. For such use, it is highly desirable to prevent fraudulent operation of the register., which is the means for apprising the customer of the quantities displaced zfrom the pump. f such means can, without great difliculty, be fraudulently manipulated, tlish'onest operators will take advantage of this ,fact to mislead and chcat the customer.

One object of the invention is to provide in a register indicator-operating mechanism with an actuator adapted to be moved intermittently to cause the indicator to progress and give the desired cumulative indications such mechanism arranged to prevent such progress by any other means than said actuator and, while pcrmitting "everse movement of the indicator to zero positionv prevents such n'iovcment beyond such position.

Another object of the invention is to provide a reciprocable actuating means for periodically engaging the actuator on each strole and capable of moving it on only one, said means including a part which can yield readily when it cngages the actuator on its inoperative strolce and can also yield after it has engaged and moved the actuator on its operative stroke but less readily than on the other stroke.

Another object of the invention is to provide. as indicator-operating mcchanism. an

escapment wheel and an associated oscillating Operating level', the teeth of said'wheel for the most part permitting retrograde Serial No. 465,789.

vent such movement, whereby the indicator cannot be moved backwards beyond. a predetermined point7 such, for example, as the o zero point of the register.

Another object of the invention is to encase the Operating mechanism in such a` manner that it cannot be, taken apart when mounted on the machine from which it is operated, and to encase such machine, or at least the above-described actuat'or and its actuating means, leaving only the indicator of the register and some controlling device for the machine accessible from outside the casing.

The invention, in an embodimentat present preferred, is disclosed for illustrative purposes in the accompanyng drawings, in which,- Fig. l is a cross-sectional view of a register, embodying the invention` illustrative also of the mounting of the register on the machine by which it is operated;

Fig. 2 is a fragmentary elevational view of the register-Operating mechanism, the enclosing casing of which has been largely broken away; w

Fig. 8 is a. 'sectional elevational view, taken on the. line 8-3 of Fig. 1 and illustrative of the preferred construction of the actuator; and

Fig. 4' is a small-Scale clevational view showing the cncased machine with the register mounted. thereon.

Referring to these drawings, the operating mechanism is completely enclosed in a suitable casing which, as illustrated consists of front. and back members 5 and 6, respectively, one of which, as 5, has a circular rim 7 to suitably space the members and complete the enclosure. These members are suitably secured together, as by screws 8,' which vare preferably applied from the back of the register for the purpose of rendering them inaccessib'le for rcmoval after. the back plate has been mountcd, as shown in Fig. l., on the machine by which it is to be driven.

The outer face of the front member 5 carries a dial suitably graduated in the desired units. as indicated at 9 in Fig. 4. For the sake of illust-ration` these units may be considered as gallons, inasmuch as the machine illustrated in connection with the register is oensinp' nuino. The instril'ze low iJ l a ineasnging` and L dioatoi', as illustrated., consists of apointer 22 to e'ngage and be aifi'e- 10 fixed to the outer end a shaft 11 w 23.

The practical result ofthis construction is to provide a projection 27 which is yieldable when engaged on either side by another projection, such as 28, but much less readily yieldable in one direc-tion than the other. Thus, on the upstroke of member 28, it will engage projection 27, but the latter tends to bcnd from its point of contact with 'collar 32 and offers considerable resistance to the projection 28. It is intended that, under such circumstances, the projection will not yield to any substantial degree until the lever 13 has been moved, butvas soon as the latter is arrestcd, it can yield, if necessary, to permit projection 28 to pass it. n return stroke of the latter, the projection 27 yields readily to permit projec-' scription that indicator 10 cannot be moved o forwardly except by means of the actuator. To further discourage improper actuation of the register7 the actuator itself is eno cased with the machine by 'which it is operated, leaving only the dial 5 and indicator 10 eXposed together with a controllingmember, as the Vhandle a (Fig. 4), for the machine. Such machine, as illustrated, is a measuring and dispensing pump which may be of the general type disclosed in Letters Patent No. 1,302,014, granted April 2-9, 1919, onan invention of John B. Davis. to' which reference is made for a full disclosure of the pump, its actuatng mechanism and enclosing casings. F or the present purposes, it will suflice to state that the pump is enclosed by a'casing b' upon which is superimposed a casing c, to 4which the register is attached, and upon the .casing c, another casing d. The casings c and d house reciprocating members for Operating the pump piston, of which members bar 29 is an exemplification. Doors e are provided to permit access, by authorized persons, to the parts enclosed within casing c. Into this casing the shaft 15 is inserted through an 'opening f, and the register is secured 'to this casing by screws 35 applied from within the casing through one of lthe doors e. With 'these doors closed and locked, the operator has accessible only the pump-operat-v `ing handle a, and the indicating and reset-s ting portions of the register. .Thus, the register is rendered proof against fraudulent actuation.

The invention has been disclosed herein,

in an embodiment at present preferred, for illustrative purposes, but the scope of the vat least one of whichis' formed to engage with said lever' to prevent turning of the wheel in said direction beyond a predetermined point and all of which teeth are formed to prevent the wheel from being turned in thev other direction except by oscillation of said lever.

2. In a register, having relatively movable indicating elements, an escapement mechanism for actuating one of said elements, including a wheel and an oscillatable lever having two arms alternately engageable with the wheel, said wheel having teeth all of which have one face so formed as to preventmovement of thewheel in one direction except by said lever and most of which have the other face so formed as to per'mit the wheel to be turned in an 'op posite direction, at least one of said teetfi having its other face so formed as to en-` able indicating elements, an escapem'ent mechanism for actuating one of said elements, lncluding a ratchet-wheel and an oscillatable lever having two arms alternately engageable with the wheel` to rotate it in one direction, the inclined face of one' of the teeth of said wheel being cut away to provide a substantially radial shoulder'adapted to cooperate with one of said arms to limit the rotation in the opposite direction of said wheel.
