FARE-REGISTER.

SPIECI ICATION forming part of Letters Patent N o. 476,741, dated June '7, 1892.

Application iiledMay 25, 1891. Serial No. 393,967. (No model.)

To all whom, t may con/cern:

Be it known that I, JOSEPH H. GREENLEAF, a citizen of the United States, residing atNew Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Fare-Registers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain novel and useful improvements in fareregisters for street-cars, stages, and other public vehicles; and the objects of my invention are, first, to provide a inachinehaving a novel form of indicating device capable of operation up to a certain given number and of indefinite repetition; second, in combination with such indicating mechanism additional registering mechanism which shall not only tally with the detail addition of the indicating-wheels, but shall also preserve a strict account of the repetitions of the indicating mechanism which have occurred; third, to provide a novel form of mechanism for this totalizing-register, and, fourth and in general, it is an object of my invention to provide a machine which shall be simple and compact in construction, positive in its operation, and not likely to get out of order; and with these ends in View my invention consists in the construction and combinations of elements hereinafter fully explained, and then recited in the claims.

In order that such persons as are skilled in the art to which this invention appertaius may fully understand its construction and method of operation,I will describe the same in detail, reference being had to the accompanying drawings, which form a part of this specification, and in whichV Figure 1 is afrontelevation of my machine; Fig. 2, an end elevation from the right hand of Fig. 1; Fig. 3, a front elevation with the case sectioned; Fig. 4, a section at the line :n @c of Fig. 3, certain internal parts being shown in end elevation; Fig. 5, a horizontal section on the line y y of Fig. 3; Fig. G, a section on theline z .c of Fig. 3; Fig. 7, a vertical section on the line n o of Fig. 3; Fig. 3, a vertical section on the line tu w of Fig. 3; Fig. t), a detail plan view of the stationary figure, Fig. l0, a

detail end elevation, substantiallylike Fig. 2, with the registering mechanism removed. This view is the actual size of the machine, preceding views havi ngbeen reduced one-half.

Like numerals of reference denote the same parts iu all the tigu res of the drawings.

The fare-register, which forms the subjectmatter of this specification, is adapted to be fastened to the end or other convenient point against the wall of the street-car or other vehicle in connection with which it is to be used. To this end the inclosing case 1 is provided with means of attachment, such as the perforated ears 2. This case has within it and attached to the back thereof a base or frame 3, upon which the moving parts of the register are mounted.

4 represents a pair of standards projecting outward at right angles to the base, and in these standards is journaled a horizontal shaft 5, which constitutes the main shaft of the machine.

6 is a units-indicating wheel fast upon and adapted to revolve with said shaft. Near its outer end said wheel carries a ratehet-wheel 7, having ten teeth, and also a grooved wheel S, around which extends a friction-band 9, having its ends L.ecured to the frame. The contact of said band against the wheel is rendered elastic by means of a spiral spring 10, interposed in the length of the band.

The outer end of the main shaft heretofore referred to bears a spur-pinion 1l, whose function will be hereinafter explained.

12 is a bell-crank lever with its arms substantially at right angles. At its elbow it is fulcru med about the main shaft 5.

One of the arms, which I denote by the numeral 13, carries a pivoted actnating-pawl 14., whose end engages the periphery of the ratchet-wheel 7 and is held in contact therewith by means of a spring l5. The other arm of said lever, denoted by 1G, has pivoted thereto a draw-link 17, which projects outward through the case and is adapted for the attachment of the pull strap or cord in any desired manner. A stop IS, having two abutment-shoulders, limits the throw of the bellcrank lever by engagement with its arm 13. Said bell-crank lever is spring-retracted by means of a spiral spring 19, whose ends are IOO connected, respectively, with the arm 16 of the bell-brank and a bracket 20, secured to the frame. Another bracket 2l projects upwardly from the frame and has pivoted thereto a retaining-pawl 22, held in engageuient with the ratchet-wheel by means of a spring 223 and provided with a bell-hammer 24, which operates in connection with a bell 25, mounted upon the frame and adapted to ring at each registering action of the machine.

The operation of this part of my invention is as follows: By pulling the operating cord or strap the bell-crank lever will be vibrated about its center and the operati ng-pawl, whose end engages the face of one of the ratchetteeth, will carry the ratchet and the unitsindicating wheel one step, the abut ment-stops permitting' to the bell-crank sufficient movement for this purpose. As the ratchet-wheel moves forward the end of the retaining-pawl will ride upon the back of the tooth beneath it, and this movement will retract the hammer away from the bell 25. When the tooth has passed entirely beneath the retainingpawl, the latter will be drawn downward over the face of the tooth by its spring, thereby preventing any retrograde movement oi' the ratchet-wheel and at the same time causing the bell-hammer to strike the hell. The spring 19 will carry the bell-crank lever back to its original position upon release of the strap, when it drops into engagement with the next toot-h.

Upon its peripherythe units-ind icator wheel bears numerals from O7 to 9, and upon its left side (see Fig. 3) said wheel is provided with an extension 2G, which is in the form of an outwardly-projecting metallic band, having openings therethrough, ten in numberone opposite to each of the units upon the main portion of the indicator-wheel. At its eXtreme left said extension is provided with a single narrow opening 27, whose purpose will be presently explained.

.lournaled about the same shaft as the unitsindicator wheel and in line with said wheel and with its periphery inside the extension of the units-wheel heretofore referred to, is a tens-indicator wheel 2S, having its periphery numbered like the units-wheel. lts figures appear through the openings in the part 26. At the extreme left it is provided with an opening 20 in the same plane and adapted at certain times to register with the similar opening at the extremeleft of the extension of the units-wheel. The purpose of this construetion is to disclose at every hundred operations of the actuating-lever the figure 1, which is borne upon a fixed tablet 30, whose end projects inward beneath the peripheries of the units and tens wheel to a point in line with the two small openings just described. This tablet is carried upon theleft-hand standard or is otherwise secured to the frame. The

tens-wheel carries a friction-wheel 31, similar to the same parts on the units-wheel and engaged by a spring-tensioned friction-band 32.

The function of both these friction-bands is to prevent the wheels from overthrowin g, and this is necessary when the initial movement imparted to the bell-crank is particularly quick or severe. The tens-indicating wheel carries a ten-toothed ratchet-wheel 33, and the units-wheel upon its inner side carries a pivoted actuating-pawl, which projects laterally outward, so as to liein the same vertical plane as the ratchet-wheel 33. This pawl performs the earryin g movement whereby one complete revolution of the units-wheel will actuate the tens-wheel one step. This pawl 35 is normally held out oi engagement with the ratchet-wheel 33 by means of a springet, and therefore would be carried round said ratchetwheel without moving it. It is thrown into engagement with and moves it one step at each complete revolution of the units-wheel by means of a cam 36, which is aflixed tothe frame and engages a toe 37 upon the pawl in such manner as to throw the latter into engagement with the ratchet-wheel and retain it in such engagement so long as the toe engages the surface of the cam. The length of the cam is sufficient to hold the pawl against the ratchet-wheel through one operation of the bell-crank, and as soon as the toe passes out of engagement with the cam the spring throws the pawl out of contact with the ratchet-wheel, there to be retained until again brought into contact with the cam at the next revolution. Thetoe, as shown at Fig. it, projects through t-he periphery of the units -indicating wheel just at one side of the face of the tens-wheel. The inclosing case is provided with openings A, through which the figures on the indicatingwheels are seen` and also once in one hundred operations the ligure l upon the tablet in conjunction with the two zero characters upon the indicating-wheels. This stationary figure can only be seen when the two openings at the left hand of the indicating-wheels are in conjunction over this figure. Of course this only occurs once in ahundred operations of the machine, because while the units-wheel opening is over the tablet once at each rovolution and the opening in the tens-wheel once at each revolution the two will only be in conjunction with the tablet once in every ten revolutions of the units-wheel oroncein each one hundred operations of the machine.

The parts heretofore described constitute an indicating mechanism capable of automatic operation up to one hundred when made with two wheels and the stationary digit above referred to and up to one thousand when three wheels are employed and capable of repeating this indicating operation indefinitely. In connection with this indicating mechanism I use a registering mechanism, whereby not only is each operation of themachine up to one hundred duly reckoned, but each hundred is also reckoned up to ten thonsand, an d in this respect, also, indefinite repetition maybe had. The parts of the machine IOO IIO

- 44 being journaled on the shaft.

whereby this is effected are now to be described.

As has heretofore been described, the end of the main shaft bears a spur-pinion ll. This meshes with two gears 3S and 39, the former having one hundred and one teeth and the latter one hundred teeth. Both of these are upon a short shaft 40, whose bearing is in the top of a standard 41, projecting from the base. The gear38,as shown at Fig. 7, is mounted upon said shaft in such 1nanner as to carry the latter. The gear 39 is loose and revolves upon said shaft as an axis. The outer face of the gear 39 bears an annular dial 42, `graduated into onehundred equal parts, as shown at Fig. 2. The face of said dial is recessed, as appears at Fig. 7, and within this recess and at the bottom thereof is contained a gear 43, whose hub is fastened to the shaft 40, and therefore revolves with the gear 38. Like said gear 3S it has one hundred and one teeth. Around the hub of this dial 42 and journaled thereon is a double part consisting of a gear 44, having one hund red teeth, and a pointer-plate 45, upon whose outer surface, as shown at Fig. 2, is a representation of a pointer which operates, in conjunction with the figures, upon the annular dial 42. The gear 39 carries within the recessed outer face, heretofore described, a spurpinion 46, which engages with two gears 43 and 44. A fixed pointer 47, which is secured to one of the standards orother fixed portion of the machine, projects over the outside edge of the dial 42 and is adapted to indicate in connection therewith. For the sake of convenience said dial bears two sets of graduations, one adapted to operate in connection with the fixed pointer just referred to and the other in connection with the pointer on the plate 45. The pointer-plate is made in the form shown for the purpose of securing the internal gearing as against the entrance of dirt. Except for this function an ordinary pointer or dial-hand would answer every purpose.

The operation of this portion of my machine is as follows: As the pinion 1l is revolved by the shaft the two gears 38 and 39 are moved thereby one tooth at each operation of the bell-crank lever. As heretofore set forth, the gear 43 is carried with the gear 38, the gear The 'onehundred-toothed gear 39 being driven by the pinion ll,will impart to the annular dial one full turn in one hundred operations. This dial carries with itin its revolution the pinion 46, which, as before explained, meshes with both the gears 43 and 44. It is intendedthat the fixed pointer shall, in connection with the outer dial, indicate units from l to 100 and then repeat. It is intended that the finger or arrow on the pointer-plate shall indicate the rotations of the dial past the fixed pointer-that is, one step for each one hundred steps of the latter. This is accomplished by means of the gears 39 and 44,

which have teeth one hundred in number, and therefore equal to the index-spaces on each of the dials, and thc gears 38 and 43, which are given each one more tooth than the gears 39 and 44 and the index-spaces on the dial, or one hundred and one. By this differential gearing, when the dial is rotated intermittently by the operation of the pinion to bring the numbered edge of said dial into the relation which it assumes to the fixed pointer and when the dial has made a complete revolution, then by reason of the one extra tooth in the gear 43, which is carried by the similar gear 3S, and the intermeshing of the pinion 4G with said gears 43 and 44 the finger on the pointerplate will, at the conclusion of the revolution of the dial-plate, be brought into line with the first in dex-line beyond the zero-point on such dial, and thus indicate the sum of such whole revolution or one point representing one full hundred. In other words, if the finger on the pointer-plate shall indicate 9 and said dial, in connection with the fixed pointer, shall indicate 50, then it is certain that said dial, has completed nine whole revolutions of one hundred points each, and fifty steps of the tenth revolution, or nine hundred and fifty operations in all.

I claiml.
