COASTING'BECOBD DEVICE.

Specification of Letters Patent.

Patented Nov. 23, 1909.

Application filed January 28, 1909. Serial No. 472,842.

To all whom it may concern:

Be it known that we, FRANK Hunter and J.-\ .ues S. Dornn, both citizens of the United States, and residents of the city, county, and State of New York, have made a certain new and useful Invention in Coasting- Itccord Devices, of which the following is a specification.

This invention relates to coastin record devices for use in connection with tile operation of street curs, railway trains or the like.

The object of the invention is to provide means for recording the coasting tune or distance of street or other cars, railway trains or the like, that is, the time consumed or distance covered by a street car, train or the like when running with the motive power shut oil', as, for instance in coming to a street crossing, or station, thereby indicating the saving effected in the amount of current or power consumption required in the operation of the train.

Other objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location and relative arrangement of parts, all as will he more fully hereinafter set forth, as shown in the accompanying drawin and finally pointed out in the up )ended c aims.

In the drawing,-I igurc 1 is a view in diagram showing an arrangement of coasting record device embodying the n'inciples of our invention. Fig. 2 is a bro (on detail view showing a form of record controlling release mechanism employed in connection with our invention. Fig. 3 is a detail view of a record shoot. Fig. 4 is a diagram of a owcr or current curve showing graphica ly the portion of operating current. the saving of which is to he recorded. Fig. 5 is a view similar to Fig. .2 showing another form of recording mechanism included within the scope of our invention. Fig. 6 is a detail view in side elevation, parts in section, showing the record moving mechanism.

In the practical operation of street or other curs, railway trams or similar or other derives, the operating mwor is cut oil from the driving molor ho ore the our, train or lhr lilorcuclu-s tho point where a slop is to he made. In such cases the headway or monu-olmo of the on r or train carries the Hlllllt! along until the lu'akos are finally applied.

This movement of the car or train during the time the owcr is cut oil is commonly called coasting, and the time consumed in coastin represents a saving, during such interval 0 time, of current or other power employed to operate the train or car. Here tofore, so far as we are aware, no effort has ever been made to keep a record of the saving of power effected in this manner, the motormen or engineers, without special incenttve, merely exercising their individual discretion as to when to shut off the power in approaching a stopping point, and without regard to t it: idea of etlecting a measurable saving of power or current with prearranged ca culatlon. The result has been in practice, that one motorman will shut off his power at one point and another will shut oif the power at another point, with total lack of system, and, frequently without cffecting the degree of savin of wer or ourrent eonsumptiou that ot ierwxse might be possible.

In accordance with our invention we propose to em lay a recording apparatus, controlled con ointly bv the power controller and the bralte cont roller, whereby the coasting record of the car or train may he made. This record may he of the time consumed during the coasting travel of the train or car, or it may be of the distance covered during such coasting travel, or it may be of some other element which may he made to calculate the savin of current or other power by reason of ihe coasting" travel of the car or train.

\Vilh such a record as above indicated, an incentive on the part of motormen or engineers to systematically control their cars or trains with reference to the coasting travel thereof, in such maum-r as to effect the greatest amount of savin v of operating power or current, thereby rodhciug the cost of operation of the system, may he all'ordod by oflcring to such motormcn or engineers, as a bonus, a crceutage of the saving, thoroby cfi'cctcd, In the power or current cousumptiou. Any disposiliou on the part of the luolorluuu or engineer to build up a large consting" record at the expense of the time schedule for the (narration of his car or truiu may he provcuh-d or roulrolhnl by a strict luuiulcuuume of the limo schedule, or a proportional deduction from the "coasting" icons by reason of any loss from the time schedule. Of course other methods of management based on the records of consting" travel of the car or tram sccurcd the operation of our invention might readily occur to those familiar with the cond tions and circumstances of street or other railway management.

From the foregoin description it willbe seen that, in its broa est scope our invcntlon contemplates the provision of means controlled conjointly the motor and brake controllers for ma ing a record of the coastin travel of cars, trains or other moving dies.

The specific structure of the record apparatus is immaterial. In one for1n of ar rangernent, as exemplifying the principles of our invention, we em loy a cylinder indicated at A, upon whici may be carried a record sheet B, suitably prepared and ruled. This record sheet is merely indicated diagrammatically in Fig. 1. pencil or other marker, indicated at I), may is arranged to bear upon the record sheet carried b the cylinder A. This cylinder may be riven by any suitably arranged motor, such, for instance as a clock spring motor, indicated at S. Under normal running conditions of the train the record cylinder driving mechanism is looked a inst operation b a releasable and cont-r0 lable locking mec anism. One form of controllable locking mechanism which is of sim le construction is shown wherein a lockin deg C, cooperates with a ratchet disk E, 51c latter forming1 part of the cylinder driving mechanism. is dog may be normally eld in locking engagement with the ratchet disk E, in any convenient manner, as, for instance, by means of a spring F, and the release of the dog from engagement with the ratchet disk may be effected by any suitable means controlled by the proper conjoint manipulation of the motor controller and brake controller.

In one form illustrated in the drawin the release of the locking dog is effected hv means of a magnet G, the circuit of which is controlled by the main motor controller and the brake controller conjointly as will be explained hereinafter. In this form of application of our invention it will be observed 'that the record cylinder is held a inst rotation during the normal running 0 the car or train under its usual power. As the car or train approaches a station or stopping point the power is out oli' from the mam motor and the car or train continues its travcl under its gathered headway or momentum. The cutting oil of the supply of motive power eli'r-cls a release of the record cylinder operating inmahunisin. as, for instance, by oomph-tin the circuit. of magnot G, and mo-( Malitho pencil or ollun' marker l) clients a record ol'" the coasting time or (listnluin of the car or train, and

when finally the brakes are a plied to stop the car or train the record cy indcr is again arrested, and the time consumed, or the distance covered by the train or car in the interval between the shutting oil' of the motive power and the ap lication of the brakes, marks the saving e ectcd in power consumption.

In Fig. 5 we have indicated another ar rangement embodying the principles of our invention wherein instead of starting and stopping the record cylinder, the pencil or other marking device H, is automatically moved into and out of marking position with reference to the record sheet. This result is accomplished in this instance by means of a solenoid J, the core of which carries the pencil or other marker, and the circuit of the coil of which is controlled conjointly by the main motor controller and the brake controller.

It is obvious that many other specifically different arrangements of recordui mechanism may be employed and still fafi within the spirit and scope of our invention as defined in the claims.

\Ve will now describe an arrangement for effecting the control of the recording apparatus through the conjoint operation of the main motor controller and the brake controller and embodying the principles of our invention.

Reference si L, designates a solenoid, the core M, 0 which, operates a brid ing contact piece N arranged to open an to closle a circuit between the contact points 0, r.

The main motor controller handle is designated by reference sign 0, and is arranged, when in one position to close circuit between contacts c, f, and when in another position to close circuit connection between contacts g, ii.

The brake controller handle is indicated by the IEft'lt'fltfi sign 1, and is arran ed when in oli'" or. release position to cliisc circuit connection between contacts j, k, and between contacts m, 'n.

The motor controller handle 0, is shown in full llm's in position to close circuit conncction hrtwccu contacts 0, f, and to open the (llt'llli hctwccu contacts {1, /t, and the brake conh'ollcr handle I, is shown in oil or release position, thereby completing the circuits bctwccn contacts Iv, and between in, n. Under those conditions, circuit is completed from any suitable or convcnicut source through main supply wire a, Wire A, contact I. handle 0. contact 1'. wire p. coil l4, and return or grmnnl 'll'l r. lhcrcby (HUI- gizing roll I. and causing Ilia contact st rip N, to close the circuit la-lwoun contacts. I, I. 'llu-n-upon another circuit through the coil It is completed as follows from main stillply wiru a, through contact r, contact J,

wire q, wire 6', contact or, brake control handle 1, contact 16, wire t, coil L, and to return or ground wire 1'. The completion of this circuit supplies energizing current to coil L. even though the circuit throng? contacts c, f, above traced, is broken y the manipulation or movement of the main control handle 0. In other words the movement. of the handle 0 into the position indicated in full lines serves to establish a preliminary energizing circuit for the coi L, but once this coil IS energized by the c0mplctiou of this preliminary circuit, the resultin actuation of the contact strip N, estahlis ies another circuit through the brake control handle and the coil L, energized without regard to the main motor control handle 0. Ordinarily the handle 0 is moved into )osition to close circuit; between contacts a, preliminary to the movement. of said handle into complete "05 position to shut, otl' power from the main motor. This handle 0, is then moved into its 01f position as indicated in dotted lins thereby closing circuit between contacts 9, It. Thereupon a circuit is com leted through the record controlling inec ianism as follows from wire a, through contacts 0, ll, wire g, wire c, contact 9, handle 0, contact It, wire 1!, contact j, handle I, contact k, wire I, the record controlling device, as coil G, or coil J, wire 3 to return or ground wire 2*, The completion of this circuit results in the proper actuation of the recording devices to ctl'cct the desired record, and since this operation is inaugurated coincidently with the shutting off of power from the main motor, and continues as long as the brake controlling handle is in full release position it resulls that the record made is of the coastiug travel of the car or train and may be, as above explained, either the distance, or the time or other element of such travel, as may he desired. in order to furnish a basis for a calculation of the power saving and economy of operation cfi'ectcd by such coasting" travel. By the movement of the hrakc control handle I, to effect. an application of the hrakcs thc circuits of both the recording mechanism and also of the control magnet coil Ii. arc hrokcn and the recording operation is arrcsted. 'lhis,of course, marks thc end of the free com-sling travel of the car or train, and the apparatus is placed in condition for the next operation.

Having now sct forth the object and lltlllll't of our invention. and an arrangement: clnluul \'llll the principles thereof, and haring oxplaincd tho samc and its purposes, function and lumlo uf operation, what we claim as new and uscl'ul and ol our joint illrcnliou and dcsirc to Ht't'lll't!
