Specification of Letters Patent.

Application led March 1,1912, Serial No. 680,807. Renewed J'une 7, 1916. Serial No. 102,351.

To all whom t may concern:

Be it known that I, JAMES D. 'ELsoM, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Registering Mechanism, of which the following is a specification.

My invention relates, more particularly, to registering mechanism for use in connection with electrically-propelled vehicles for registering the number of stops made by the vehicle, the length of thel stops, and the number of ing from period of time, I and length of stops made by the vehicle being of value in determining the speed at which lthe vehicles should be run during difperiods of-the day for operating the passengers boarding and alightthe Vehicles lduring any given erent vehicles with the maximum economy, and the record of the number of passengers boarding and alighting fromY the vehicles being of value in determining the number of vehicles required to be run during different periods of the day to accommodate the patrons of the road to the greatest possible practical extent. f'

' lReferring to the 'accompanying drawings,

inlwhich have illustrated my invention'as embodied in` a register intended for -use on an -electrically-propelled car for registering the numberand duration of stops and the passengers boarding and alighting from the car- Figure l is a view in vertical sectional elethe section `being Fig. 2 and viewed arrow. Fig. 2 is a vation of the register, taken at the line l on in the direction of the view in elevation, partly sectional, taken at viewed in the .direc-v the line 2 on Fig. l and tion of the arrow. Fig. 3 is a section taken at the line 3 on Fig. 2 and viewed in the direction of the arrow. section takenat the line 4 on Fig. 1 and 5 is a longitudinal sectional View of one of the indicating devices illustrated in Fig. 4;' and Fig. 6, a diagrammatic'view-of the, cir-` cuit connections for operating the yregister illustrated in connection with a trolley car.

Referring to the construction.illustrated lve, the casing of the register is 'represented at 10 and, in practice, would be secured on the lvehicle in -connection with which it is to beused in any dethe record of the number surrounding Fig. 4 is a broken` of the arrow. Fig..

most reel having-wou`nd lthereon paper in` strip form as represented at 17, the free end of the strip being connected with the lower reel 16.

The strip 17 p upon which the records, hereinafter referred to,l are to be made, and which, in the operation' of the f register, is unwound from the upper reel l5 and wound upon the lower reel 16 by rotatany desirable manner, as is well known `in the art, passes over idlers 18 and 19 supported on shafts 2O and`21, respectively, journaled in the casing`10, and in its movement passes closely adjacent to a ing the reel 16 in vertically-disposed plate 22 paralleling the strip 17 and secured to the sides of the casing v10, as indicated at 23, this plate containing an opening 24 for a purpose hereinf after set forth. Located at the other side of the strip 17 'is an hour impression wheel 25 and a minute impression wheel 26, the wheell 25 being fixed on a shaft 27 j ournaledl in bearings 28 on the sides ofthecasing, and the Vwheel 26 beingfsecured to a sleeve 29 and journaled on the shaft 27, whereby the wheels 25 and 26 may be rotated independently of each other. The numbers onl the wheels 25 and'26 are spaced equi-distantly apart as represented, and eX- tend beyond the periphery of the wheels, as is common in recording devices whereinv rovision is made for impressing upon a s cet `the hour and minute when such impression is made, these wheels opposing the opening 24 in the plate 22, i

It will be understood from the foregoing that the wheel 25 is to be intermittently ro` tated. a one-twelfth of' a 'revolution every In the drawings,'the shaft 27 and Vsleeve 29 are shown as provided with pulleys 30 and 31, respectively, these pulleys, in practice,

i to the casing as indicated at 36 and conopening 24 and taining an opening 37 registering with the through which a portion of the peripheries ofthe ,Wheels 25 and 26 project. Confined y and the strip 17 of paper is an inked ribbon 38'which passes through opening 39 inthe plate near its ends andis rolled upon suitably supported spools 40, these spools,

lin practice, any suitable mechanism for shiftmg the riby being .preferably connected with bon 38 to successively present to the type -on the Wheels 25 and 26 fresh portions of the ribbon, in order that a clear impression may be 'made on the strip 17. L* I Coperating with the ribbon`38 and the type on the wheels 25 and 26 is a striker 41 .which is carried on the end of one arm of a bell-'crank lever 42 forming the armature of 'if an electro-magnet 43 in the casing'lO and secured -to a Wall thereof, the striker 41 being so `arranged that when the armature 42 is `attracted to the magnet 43 it will be projected through the opening' 24 in the plate which oppose` the 22, thus causing the type,

the

saidstriker, to make an impression` on strip 17.

. In the operation of the register, the striker 41 is operated at predetermined intervals, in

.the construction illustrated it beingintended that said striker be operated once every minute, and in time with the movement of the wheel 26,whereby the strip 17 of paper, as

. it is drawn through the machine, will have printed thereon, 1n longitudinally-'spaced relation, numerals indicating each succeeding` minute.

- Any suitable mechanism may be provided for operating vthe striker 41. In the con-jV struction illustrated, the striker is operated electrically through the medium of an electric circuit vby momentarily closing the circuit once every minute, this beingeifected,vv

in'theconstruction shown, through the mediumof a disk which, in practice, would be so connected with the clockfmechanism in the casing I'34 as to kcause the disk 44 to make acomplete rotation once every minute'. The peripheryof this disk is insulated as represented'at 45,l with the exception. of a small v'section of metal 46 which serves to close the circuit between two contact-fingers 47 and between the wheels 25 and 26 l 48 interposed in circuit with a source of electrical energy and the magnet 43 as hereinafter described.

In the arrangement illustrated, means are y provided for indicating onthe strip 17 the number of passengers getting on or off the car at either end of the latter, these devices in the illustrated embodiment of my invention being manually controlled and comprising` the following mechanism:

Depending from brackets 49 secured to the casing and extending transversely thereof are a plurality of electro- magnets 50, 51, 52 and 53, the armatures of which, represented at 54, are of bell-crank form, being fulcrumed, as indicated at 55, to spaced lugs 56 depending from the brackets 49. The lower arms 57 ofthe bell-cranks 54 coperate'with the cores 58 of the magnets 5Q-to 53 inclusive, and the upper arms 59 of these ybell-crank levers are provided with fingers 60 which, respectively, oppose openings 61, 62, 63 and 64 in the plate 35. In practice, the fingers would be provided with any `means for making a mark, as for example a pencil point, and, in operation, the respective,electro-magnets 50 to 53. inclusive would be energized, as hereinafter described, Vto cause'the fingers 60 to be momentarily moved into contact with the sheet 17 for making a mark thereon,` the bellcrank levers 54 being yieldingly held in the position illustratedfof the one shown in Fig. l with the strip 17 by means of springs 65 -connected at opposite ends with the arms 59 of the respective levers 54 and with pins 66 Arising from the plates 49. Each of the lein which the finger 60 is out of contactvers 54 is controllable independently of the others thereof through `the medium of electrical circuits hereinafter described, the opening and closing o f which are controlled by switches 67, 68, 69 and 70.v In practice, the marks made by the respective fingers 60 would indicate the number' ofpassengers boardin and alighting from the car at the r forwar and rear platforms, respectively. Inv the arrangement illustrated, two ofthe circuit devices 67 to 70 inclusive would be vlocated on the frontplatform accessible to the motorman, and the other two on the rear platform accessible tothe conductor. One of each of these pairs of switch-devices would be the medium through which the cooperating magnets of the series 50 to 53 thereof wouldbe operated for actuating the respective fingers 60 to make such the paper `17 as willindicate thereon the giumber of passengers'boarding thecar at any. given period of time, and the other of the switch-devices 67 to 70 inclusive would be the medium through which tlie other two of the .magnets 50 'and 53inclusive would beoperated for causing the fingers 60 cooperating therewith to make marks on the sheet 17 indicating the number of passengers alighting from the car.

In the ypreferred illustrated embodiment of my invention, means are provided for indicating on the sheet 17 'the number of times the car stops and the length of the stops during any given period of time, a description of these means being as follows: Located lin the casing and supported therein on a bracket 71 secured to the'casing-Wall is an electro-magnet 72, the armature of which, represented at 73, is of bell-crank form and fulcrumed, as indicated vwhile such current is turned on,

'at 74, to spaced arms 75 on thevbracket 71.

The arm 76 of the bell-crank 73 forms the armature-proper of the magnet 72 and coperates with the end of the magnetizable core 77. The other arm 78 ofthe bell-crank 73 is provided with lany desirable means for projection through an opening 35",L in the plate 35 to make a mark upon the sheet. 17 when the magnet 72 is energized, drawing the armature 76 toward the core 77 andV swinging the arm 78 toward the paper y17 against the action of a coiled spring- 7 9, secured to the last referred-to arm and to a `pin 80 von the bracket 71. The illustrated means carried by the arm 78 formaking thel desired marking on the paper 17 comprises an angular extension 81 carried by the-arm 7 and provided with a chamber 82 contain-` ing an ink-soaked wicking 83 held in place by a plug 84. The end ofthe extension 81 is slotted as indicated at 85 and contains a marking disk 86 which is journaled there- 1nl on a pin 87 to extend into engagement with the wicking 83, wherebythe periphery of the disk 86 is constantly supplied with ink. y l In the arrangement illustrated, the magnet 72 is caused to be energized aty all times,

excepting when the car 1s at a standstill, Aso that the marking disk 85 will be in contact with the sheet 17 during theentire time the car is in motion,.,but will be withdrawn from Vcontact therewith when the car is at rest,

and to effect this operation ofthe marking device I provide circuit connections and electrical devices, hereinafter more fully described, whereby the' magnet is energized by the current supplied to the motor of the car, and upon shutting' olivn the current to the motor the magnet 72 is energized by the regenerative current produced by the rotation of the Inotor-armature under the momentum of the car when the current to the motor is Shut olf.

Desirable circuit connections for the various indicating devices hereinbefore de-y scribed when the registering device is usedl in connection with a trolley-car, are'represented in Fig. 6, a description of which is as' follows: A trolley wire is represented at 88, this wire, as is common in practice', leading from the power station where vit is oonlwhich, in practice,

connects with a wire 118 nected with one side of a dynamo (not shown), the` other side thereof being grounded. A trolley is diagrammatically represented at 89, a .wire 90 connecting the trolley with the movable arm 91 of a 'switch would be the usual cur` rent-controller `provided on trolley cars. The stationary contact of the switch or controller, represented at 92, is connected by a wire 93 with one of the brushes 94 of the car-propelling motor 9,5, the other brush 96 thereof being, grounded as represented at' 97, thedescrlbed circuitv connections between the' trolley, motor vand controller corresponding to the usual circuit connections in trolley cars. A relay 98 has one of its termlnals connected with Vawire 99 leading armature of the relay 107 being represented atl 110. This armature, which is grounded as represented iat 111,` is

to be moved into and out of'enga'gement with ka, contact-point 112, a spring 113 being provided for the purposeof normally lholding the armature 110- out of engagement with the contact-point 112 and against a stop 114. The terminals Y connected, respectively, with wires 115 and 116, the wire 115 connecting with the conadapted of the electro-magnet 72 are tact-point 112 and with a wire 117 connected with the contact-point 103. The wire `'116 connects with one of the terminals of 'the magnet 53, the other terminal of this magnet connecting with a wire 53, which grounded as represented at l119, the push-switch70 being interposed in the wire 53a. One of the terminals of each ofthe magnets 50, 51, and 52 is connected withv the wire 11,6 through the medium' of wires 120, 121 and 122, respec- .i

tively, the `other terminal of the magnet 52 being connected' with the wire 118 through the medium of a wire 123, in which latter the push-switch 69 is interposed; The other vterminal of the magnet 51 is connected -with a wire 124 in which the switch 68 isv interposed, this wire connecting with a wire 125 groundedv as, represented at 126. A wire 127 leads from the other terminal of the.

magnet4 50 and connects with the wire 125, the wire 127 having interposed therein the switch 67. The wire 116is connected with a Wire. 128 which is joined to a' 'wire 129 arrangement connected with one terminal of a battery 130 or any other suitable source of electrical supply, theother terminal of the battery being grounded through a wire 131 as represented at 132. The contact-arm 47 is connected with, the wire 129, its coperating` arm 48 being connected with a wire 133' which connects with-one of the`terminalsof the magnet 43, the other terminal of this magnet being connected with a wire 134 grounded as indicated at 135.

1t will be understood from the foregoing that the paper is gradually drawn from the reel 15 and wound upon the reel 16 by rotating the latter, the sheet 17 having periodically marked thereon, by the actuation of the 'striker 41, numerals representing successive periods of time, as for example each. succeeding minute, whereby the spaces loe-.-

its metal portion l46 contacts the arms 47 and 48, to complete a circuit from the ground at 132 through the wire 131 to the battery 130, thence through wire 129 to contact-arm 47, the section 46 of the disk 44, the contact-arm 48 to wire 133, thence through the magnet 43 and through the wire 1.34 to the ground at 135.

Assuming that the switches 67 and 68 are located on the front platform and the swlitches 69-'and 7 0 on the rear platform, the indicating mechanism controlled by the closing of the switches 67 and 69 being provided foi-.indicating the number of passengers boarding the car, and the indicating mechanism controlled by the switches 68 .and 70 beingl provided for indicating the number ofl passengers alighting from 'the car, whenever a passenger boards the car or leaves -t at either the front or rear platform,I the operator, whether he be the'motorman or the conductor, as'the case may be, switches 67 to 70, which thereby causes the respective one of the magnets 50, 51, 52 or 53, lwhich is controlled bythe switch oper' -by the switch operated, and thence through said coil and to the ground through either the wire 118 or 125, as the case may be, a from the-y ground through the wire' 131 to the battery 130.

vthrough wire 131 a illustrated, makes a complete rotation once every minute, serving, when 102 to the ground coil 72, the current Aat 1111 through armature 110, contact-point i 112, wire 115, magnet 72,-wires 116, 128 and '129 to battery closes the appropriate one. of the push- '1`he effect ot thus operating an electromagnet as stated, is to cause its finger 60 to be projected against the sheet 17, thereby making a mark thereon.

The operation of the runningtime indicator of which the disk 86 forms a part -is as follows The movement ofthe 4controllerarm 91 by the operator into engagement with the 'contact 92 to close the circuit in which the motor 95 is located for operating the motor, closes the circuit through the dynamo at the power house, the trolley-` wire 88, trolley 89, wire 90, controller-arm 91, contact 92, wire 99, magnet 98, wire 100 to ground at 101 ythus cmpleting 'the circuit and energizing` the magnet 98. Thus energizing this magnet causes the arm 102 to be moved into engagement with the contact-point 103, thereby establishing a circuit through the wires 128 and 116, magnet 72, wires v115 and 117, armature 102 to ground at 105, and .from ground at `132 nd battery 130. So long as current 'is flowing from the ywire 88 through the motor 95, the armature 102 will be held in engagement with the contact 103, with the result of causing the disk 86 carried by the armature 76 to vbe held against the paper 17. As soon as the controllerswitch 91 is operated to open the circuit in which the motor 95 is interposed, the armature 102 assumes the position illustrated in Fig. 6 under the action of the spring 106, wherein it bears against the contact-point 104. ,The rotation of the armature of the motor 95,y after current thereto is shut ofi', due to the momentum of the car in coasting, causes a regenerative current to be produced which travels from the brush 96 through the armature of the motor to the brush 94, thence throu wire 108 to coil 107, and from the coil 157 through the wire 109 vto contact-point 104, and armature l at 105, thereby completing the circuit through the grounded brush at 97. Energizing the magnet 107 causes the armaturey 110 to engage l 112, thereby closing the circuit through the passing from the ground 130 and from the latter through the wire 131 to ground `at 132. The effect of energizing the magnet 72 by the closing of the circuit through the inedium of the armature 110' is the same las that described of the closing of the circuit with the contact-point through the armature 102. It willbe understood from the foregoing that as the coil 7 2 is energized by current traversing a cir-l cuit which is held closed during the entire time that the current is passing from vthe wire 88 to the motor 95, and ,by a separate circuit traversed bythe regenerative cur' rent produced by the rotation of the arma- I period of time.

'72, the current may be taken from ture of the motor 95, which circuit is created immediately following the break in the circuit controlled by the current passing from the wire 88 to the motor 95, that the marking roller 86 will be held against the paper 17 duringthe entire time that the car is in motion.

It will be manifest that one observing the sheet 17' after it has passed through the registering mechanism,lmay readily determine the number of times that the car was stopped during any period of time, the length of time that the car wasfin motion and consequently the'length of time it was standing still, and the number of passengers boarding and alighting t'rom fthe car during any fore the operating department of an electric railroad, certain of the valuable factors are -presented which are necessary in determining the speed at which the car should be ruin# during different periods of the day for operating the cars with the maximum economy, and determining the number of cars required to be run during different periods ofthe day to accommodate the patrons of the road to the greatest possible practical extent. Furthermore, by' proving means for indicating the number of passengers boarding and alighting from the car stops made by the car, the relative length of time' per passenger required for loading and unloading cars of different types may be readily determined.

Instead of providing a separate source of electrical supply, as for example ajbattery or storage cell, represented at 130, for energizing the magnets 43, 5() to 53 inclusive, and the trolley 89, as'will bey readily understood by those skilled in the art, f

Various other modifications and alterations may be-made in trated without departing froml the spirit of my invention, the particular construction shown being illustrated merely for the purpose of disclosing what I now regard as'the preferred embodiment of my invention, `but without any intention of limiting my invention furtherthan the prior art may require.` 4 What I claim as new, and desire to secure by Letters Patent, is-
